[0067] First of all, FIG. 1 shows a special, already existing toilet bowl 100 in a longitudinal section, which is suitable for separating urine and the solid components of the excrement, including the toilet paper used and the flushing water, at the source. For this purpose, this toilet bowl 100 has an additional platform-shaped base 101 at the front, which extends from the front towards approximately the middle of the bowl 100 and ends there in a sloping draining nose 102. The urine is collected on this base 101 and then runs over this draining nose 102 into a collecting chamber 103 at the bottom and is drained off via a small siphon 104 through a separate, small-dimensioned pipe 105. It can thus be led into a separate container and collected there for separate further use. The solid excrement falls downwards behind the drainage nose 102 into the siphon water 106 of the large siphon 108 and then enters the discharge pipe 107, which leads out of the back of the siphon 108 from the toilet bowl 100. Furthermore, the invention deals with the treatment of these solid parts of the excrements as well as the toilet paper used, which is also discharged through this large siphon 108 together with the excrements and the flushing water.
[0068] FIG. 2 shows a conventional installation unit for wall installation, for subsequent installation of a wall-mounted WC, in a plan view. It includes an installation frame 200, which rests on associated feet 202 in a height-adjustable manner and fits as a whole into a bay cut out of a wall. Such a bay in the rear wall generally measures 500 mm in width and 280 mm in depth, as well as up to approx. 1500 mm in height. In order to create more space in new systems for the installation module for the tubular bag packaging of solids, which is still to be introduced, the bays could also be extended upwards to room height. Within this installation frame 200, the cistern 201 can be seen at the very top in this example. Below this, a cover 206 can be seen, in which the buttons 209 for operating the cistern 201 are located. The connection pipe 205 for the flush is located above the connection support 204 for the discharge pipe 107 from the siphon in FIG. 1, and next to it, slightly below, the threaded bushes 203 for screwing on the wall-mounted toilet can be seen, as well as any electrical connections 207 for connecting an under-shower toilet and signal lines for controlling the entire system via a keypad 209 with display 210 above the toilet. This can be used to trigger a flush and, if an under-shower toilet is installed, to check its maintenance status.
[0069] As FIG. 3 shows on the basis of a sectional view of a house with sewer connections, there is a discharge pipe 110 from the water closet toilet 100 for urine, and a larger 111 for the solid excrement still to be treated, as will be shown. Next to it is a drainage pipe 112 from a bathtub 113, from a washbasin 114 and from a washing machine 115, which leads in the conventional manner into the sewer 119, then into a sewer 109 and from there finally into a sewage treatment plant. The solid excrements as well as the toilet paper, on the other hand, are specially treated according to the present concept and hermetically packed in buoyant bags, and these bags are then transported away floating in the flushing water. They can be retained in a collection container 117 as shown here and are disposed of from there from time to time, or they float with the flushing water in the sewer 119 and into the sewer 109 to the sewage treatment plant, where they are separated from the waste water and disposed of separately.
[0070] The bags are therefore either collected in decentralized collection containers in collection stations for a single house or several houses, for example, or collected somewhere on the way to the sewage treatment plant and removed from the sewage system, or this only happens in the sewage treatment plant. In any case, it is important that human waste does not get into the sewer system water in the first place. Both urine and faeces increasingly contain pharmaceutical residues, which are difficult or impossible to remove from sewer water. Water enriched in this way can have a negative impact on the fauna and flora of bodies of water despite being treated. For example, it has already been established that hormones in wastewater, such as excreted active ingredients from contraceptive pills, have a negative impact on the fertility of fish and other aquatic organisms. It is therefore advisable to tackle this problem at the very beginning and not to contaminate the rinsing water with urine and excrement, but rather to use it solely as a transport medium. This is precisely the thrust of the present concept, namely that the faeces should pollute as little water as possible, but that the flushing water should be used solely for transporting hermetically packed bags and its pollution should be avoided as far as possible. Firstly, this relieves the burden on wastewater treatment plants and, as mentioned above, also helps to prevent pharmaceutical residues from entering rivers and lakes and ultimately groundwater.
[0071] In the following, it is shown how such hermetic packaging of the solid excrements according to this concept and the device required for this can be implemented in a compact manner. The device, if realized as a built-in unit, then has a width dimension like all other common standard elements of 500 mm or, more advantageously, 750 mm. The connection points for the flush water inlet and outlet must have the usual dimensions so that commercially available WC systems can be connected to this module. Toilet models as shown in FIG. 1, which are able to separate the solid and liquid outlets in the toilet, such as those already available from TOTO of Toijs Toki Co. Ltd. in Japan, or the Urine Trap toilet from Keramik Laufen AG, Wahlenstrasse 46, CH-4242 Laufen, are advantageous. The actual treatment of the solids to produce hermetically sealed, pillow-shaped bags is carried out exclusively by the device according to the invention. In various stations, the solids are portioned and hermetically packed to such an extent that a bag can float independently through the pipe system in an existing or new drainage pipe system. The advantage of this disposal method is, among other things, that there is no additional burden on the user or operator for the operation of the facility in the household, except that a packaging material cassette has to be replaced periodically or disinfectants have to be refilled. However, this only corresponds to a maintenance cost similar to that of a shower toilet.
[0072] FIG. 4 shows a built-in unit 1 for implementing the concept of packing the solids in a built-in bay installed as a complete built-in module, similar to the way a module is conventionally used for installing a cistern in a bay in the wall behind the toilet.
[0073] The built-in unit 1 is enclosed by a steel frame 49, which stands on the bottom of the bay in the wall. The connection pipe 2 for the discharge pipe 107 of the toilet bowl 100 from FIG. 1 can be seen at the bottom of the installation module. This leads into a solids separation tank 3. A riser pipe 4 leads up from the solids separation tank 3 to a solids tank 5, at the bottom of which is a portioning device 6 in the form of a drum with a valve 7 underneath. From this, a downpipe 8 leads into a tubular bag packaging unit 9. In its lower area, a change cassette 10 can be seen, which contains tubular bag material on a roll. The waste water pipe 11 leads from this tubular bag packaging unit 9 into the sewage system. The rinsing tank 12 with fresh water is located centrally at the top and to the right of it is a gray water tank 13. A brown water tank 14 is installed at the bottom right, the water from which is used for the first rinsing cycle. The connection 16 for the rinsing water can be seen in the middle of the cross strut 15 of the steel frame 1. On the right above the waste water pipe 11 is the power supply 17 and above it an electronic computer unit 18 for controlling the entire system. In the uppermost area on the right-hand side of the built-in unit is an ultraviolet disinfection unit 19 for disinfecting the rinsing liquid in the grey water tank 13. To the left of this is a control panel 20 with displays and buttons for controlling and operating all the system components. It is clear that the entire post-treatment of the solid components of the outlets must be carried out absolutely odor-tight in a hermetically sealed system, but the components of the system must still be accessible for technical maintenance or repair if necessary. Appropriate odor-tight doors are provided for this purpose, which can be opened if necessary.
[0074] FIG. 5 shows the lower area of the installation unit as seen from behind, shown separately. In particular, the tubular bag packaging unit 9 can be seen here on the right and the solids separation tank 3 below it. To the left of this, a distributor in the form of a rotary valve 21 can be seen. The discharge pipe 107 (FIG. 1) from the toilet is connected to this distributor or this rotary valve 21 and the solids arriving from above as well as the flush water and the urine then enter the solids separation tank 3 via pipe 23 in normal operation or, in fault operation, directly into the downpipe 24 via pipe 22, which leads into the sewer system. It is clear that the arrangement of the individual components within an installation module can be designed differently, depending on the design of the individual components. However, the solids tank 5 as well as the rinse water tank 12 and the gray water tank 13 must be arranged as high up as possible.
[0075] FIG. 6 now shows a schematic representation of all components of the built-in unit according to the invention for separating and bagging the solid excrements. The toilet waste, i.e. the solid excrement, the toilet paper and the urine, if it is not drained off separately beforehand, passes from the gray water tank 13 arranged at the top, which contains approx. 4 liters of gray water, from the toilet bowl 100 via the siphon and rotary valve 21, when the latter is in position 1, into the solids separation tank 3 after a flush triggering by the gray water valve 93. The solids sink downwards therein and solids sensors 89 are activated. These switch on the solids pump 28 with integrated chopper 26 and the solids pump 28 pumps the solids, mixed with grey water, upwards via the open valve 30 via the riser pipe 4 into the solids tank 5 placed as high up as possible in the installation module. As soon as the solids sensors 89 detect the absence of solids in the lower solids separation tank 3, the solids pump 28 switches off and the valve 30 closes to prevent the aqueous solids slurry from flowing back. The riser pipe 4 also serves as a reservoir for the solids slurry. The riser pipe 4 is always filled.
[0076] At the same time, the excess gray water flows passively via the retention strainer 29 and the open brown water valve 97 from the lower solids separation tank 3 through the overflow pipe 78 into the brown water tank 14 with its approximately 4 liters of usable volume, measured up to the mouth of the feed opening of the overflow pipe 78. A vent line 96 branching off from the top of the brown water tank 14 discharges the excess pressure generated by the filling into the sewer system. After reaching the 4 liter limit in the brown water tank 14, the overflow valve 91 is opened to lower the content of the brown water tank to 2 liters.
[0077] Once this is achieved, a post-rinse from the fresh water tank 12, which is supplied with fresh water via valve 97, is triggered with approximately 2 liters through valve 95. This flushes the toilet siphon. This relatively clean water now also flows passively into the brown water tank 14. At the end of this second flushing and filling process, 4 liters of the brown water, the quality of which has thus been improved, is conveyed by the feed pump 32 into the UV disinfection system 19 arranged above. The feed pump 32 is switched on intermittently in order to convey only as much brown water as the UV disinfection system 19 can process. If the grey water tank 13, which is supplied with fresh water via the valve 98 and fed by the disinfection system 19 via the line 99, is not filled to 4 liters by the feed pump 32 after delivery is complete, it is automatically refilled with fresh water. This two-stage rinsing process, first with gray water and then with fresh water, proves to be particularly economical. Only 2 liters of fresh water are required and supplied for a 6-liter flush. This saves precious fresh water.
[0078] As usual, the toilet control panel has a small and a large flush button. The large button is used for the toilet flush with fixed outlets, the small button for urine flush only. The following situations can be distinguished: [0079] A) Pure urine output: With pure urine output, the small button triggers flushing through the fresh water tank 12. The rotary valve 21 is switched to position 2 immediately before flushing and the urine flows conventionally into the outlet pipe 31 and thus into the sewage system. [0080] B) Incorrect manipulation with large button: If the large button is accidentally pressed after no solids have been dispensed and the solids sensors 89 have not detected any solids in the solids separation tank 3, a 4-litre grey water rinse is triggered. Therefore, no 2-liter fresh water flush is triggered. The unused gray water flows into the brown water tank 14 in which the overflow valve 91 is closed. The feed pump 32 intermittently pumps the unused grey water back into the UV disinfection system until the grey water tank 13 is filled again. [0081] C) Overloading the system: If the toilet is used frequently, for example at parties or when there is a large number of guests in the home, the system may be overloaded: It may be that the processing of the previously discharged solids has not yet been completed. In this case, the system switches to emergency operation. The rotary valve 21 switches to position 2 and valve 94 on the fresh water cistern 12 in the module opens and flushes 4 to 5 liters of solids into pipe 31 for the sewage system. As soon as the processing of the solids in the background is complete, the system switches back to normal operation.
[0082] A separate drain 25 for the separately collected urine leads out of the toilet 100 into a separate collection container, not shown here. The rotary valve 21 below the siphon of the toilet 100 is motor-controlled and can assume three positions: A first position 1 for normal operation, in which the incoming flush material consisting of water, possibly also urine if this is not collected separately, and solids such as excrement and toilet paper is passed into the subsequent solids separation tank 3. A second position 2 is used for malfunction operation, in which the rotary valve 21 discharges the flushed material directly into the drain pipe 31 in the conventional manner and then into the sewage system, and a third position 3 is intended for cleaning operation, for backwashing the subsequent solids separator tank 3; both the rotary valve 21 and the solids separator tank 3 can be cleaned and flushed through by cleaning nozzles arranged inside them. It is planned to connect the computer 18 of a PLC controller (FIG. 4) to a web server so that the status of the system can also be queried and displayed decentrally. Webcams installed in the interior can also be used for this purpose, which in turn can be cleaned by cleaning nozzles as required.
[0083] During the rinsing process, the excess gray water flows passively via the retention strainer 29 and the open brown water valve 89 into the brown water tank 14 with approx. 4 liters of usable volume from its feed opening. A vent line 96 discharges the excess pressure generated by the filling into the sewer system. The overflow valve 91 is open and a filling volume of approx. 2 liters is reached after a defined time. Once this is reached, flushing from the fresh water tank 12, also with 2 liters, is triggered by valve 95 and the overflow valve 91 is closed. This relatively clean water now also flows passively into the brown water tank. At the end of the second filling process, the 4 liters of brown water improved by fresh water is intermittently conveyed into the UV disinfection system by the feed pump 32. The solids separator tank 3 is always filled up to the L.sub.max mark. When the level L.sub.min is reached, the solids feed pump 28 switches off in any case, as no more material can be sucked in below this level.
[0084] From the solids tank 5 placed at the very top of the built-in unit, the viscous slurry of excrement, toilet paper and a small amount of water is dispensed into the tubular bag packaging unit 9 arranged below via a portioning device 6 and a valve 7. The filling level of the solids tank 5 is monitored by a sensor so that the solids pump 28 can only run if the level in the solids tank 5 is not too high. The valve 7 is opened and closed under the control of the portioning unit 6.
[0085] A vent line 33 leads from the solids tank 5 into the drain pipe 31 to the sewer system so that excess pressure can never build up in the solids tank 5. Down from the portioning device 6, an emergency line 34 leads via a solenoid valve 35 into the drain pipe 31 and into the sewer system. If, for any reason, the tubular bag packaging unit 9 should be defective, the solids tank 5 can be emptied directly into the sewage system.
[0086] The concept presented so far relies on a fecal matter pump arranged at the bottom of the solids separation tank 3 for the upward transport of the solids, which crushes the solids and transports them together with rinsing water into the upper solids tank. An alternative realization for this upward transport of the solids is presented below, in order to subsequently ensure the further processing of the solids or the slurry of solids in the dosing device for dispensing into the packaging unit. As an alternative to the system described above, the 120 degree rotary valve could/should not be omitted here and the upper gray water tank could also no longer be necessary, and thus also not a WC flush in two phases. This would simplify the system considerably and would result in conventional water consumption during flushing.
[0087] A lift system is used for this purpose, with a lift basket that can be moved up and down, as this lift system is shown in FIGS. 7 to 10. When the toilet flush is triggered, the solids and the flush water enter the lift basket 121 via the inlet pipe 120 of the lift system. The solids are deposited in the lift basket 121 and the flush water is discharged directly into the sewer system via the side slots 122 in the lift basket 121. The bottom of the lift basket 121 is formed by a lift basket bottom flap 123, which is held in the closed position by means of a tension spring or torsion spring. Once filled, the lift basket 121 is raised. For this purpose, a drive is provided by two threaded rods 124 arranged symmetrically to the lift basket 121 with the two threaded guide nuts 125 on the lift basket 121. A drive motor 126 is connected to the two threaded rods 124 via a toothed belt 127. Magnetic switches signal the positions of the lift basket 121 to the control unit. The lift basket 121 is kept on track by guide profiles 128 arranged on both sides. For this purpose, complementary guide ribs 129 are fitted on both sides of the lift basket 121. Both profiles 128, the fixed lateral ones and the guide ribs 129 on the lift basket 121 are V-shaped at their ends, so that correct guidance is always restored when the lift basket 121 is lowered.
[0088] FIG. 8 shows the situation when the lift basket 121 is moved upwards. of its lateral guide ribs 129 have already moved upwards out of the profiles 128. Once the lift basket 121 has reached the upper position, the guide ribs 129 on the sides of the lift basket 121, which previously slid upwards in the guide profiles 128, have moved out of these and the lift basket 121 thus hangs freely on the two opposing guide thread nuts 125. These nuts 125 are pivotably mounted on the lift basket 121, so that the lift basket 121 can now be tilted about the pivot axis 130 in this freely suspended position.
[0089] In FIG. 9, the lift basket 121 is shown in the position swung out laterally about the axis 130. In this swung-out position, it protrudes into a discharge chute 131. For the swing-out, for example, a catch hook not shown here grips the lift basket 121 at a lower lateral connection point and swivels or tilts it until the lift basket 121 is aligned with the discharge chute 131. A further catch hook grips the lift bottom flap 132 and opens it against the acting spring force until the solids stored in the lift basket 121 slide out of the lift basket 121 for further processing and enter the portioning device. It is also possible to combine the two movements of swinging out the lift basket 121 and folding out the bottom flap 123 by means of a kinematic drive.
[0090] If the lift basket 121 is emptied, its movements run in the reverse direction and sequence analogous to that described above. The spring on the lift bottom flap 123 closes the lift basket 121 again and during the subsequent downward movement of the lift basket 121, it is centered by the V-shaped guide profiles 128 and held in place. In the event of a malfunction of the system, the lift basket 121 can be positioned at half height and the solids are transported directly into the sewer system as usual or conventionally.
[0091] These can be pressed into cylindrical solids by screw compression (meat grinder principle) or a similar principle. The solids are dosed by the number of turns of the screw compression. They are then dispensed in the packaging unit described below. Alternatively, the solids could be dosed with the addition of water and then mixed to form a slurry with a defined viscosity in order to then pass through the dosing device into the packaging unit.
[0092] FIG. 11 shows the solids tank 5 and the portioning device 6 for the portioned dropping of solid portions from the solids tank 5 into the tubular bag packaging unit 9 in an exploded view along a central axis of rotation. At the top, the solids tank 5 is shown open at the top. Below this, the portioning device 6 can be seen with a rotor housing 36 and an inlet opening 37 and a swivel lever 38 to be inserted therein. The rotor 43 is shown below the rotor housing 36 and has a through channel 39. At the bottom you can see a stationary rotor housing base 40 with its outlet opening 41 and below it an electric double drive 42 with two coaxial axles. One axis 47 rotates the rotor 43, another axis 48 rotates the swivel lever 38 into the two intended rotational positions.
[0093] FIG. 12, which shows this portioning device according to FIG. 11 viewed from below at an angle, is used to explain it further. The through-channel of the rotor 43 is located under the inlet opening 46 of the rigid rotor housing 36. The swivel lever 38 rotates slowly over the inlet opening and fills the through-channel of the rotor 43. The swivel lever 38 can be operated in a 360 rotation or also in a reversed direction. The rotor 43 then continues to rotate until its passage channel 39 is located above the outlet opening 41 in the rotor base 40. The mixture now flows downwards via the valve 7 into the tubular bag packaging unit 9. Two lateral openings at the top of the through-channel 39 of the rotor 43 and in the opposite rotor housing 36 prevent the formation of a vacuum, which would hinder the discharge of the mixture portion, by means of an air supply.
[0094] FIG. 13 shows the assembled portioning device 6 seen from diagonally above and FIG. 14 shows it seen from diagonally below. This portioning device 6 thus dispenses measured, equally sized portions into the tubular bag packaging unit 9 via the dispensing valve 7 arranged below it. This tubular bag packaging unit 9 is described in more detail below, based on its mode of operation on the time axis.
[0095] FIG. 15 shows the interior of the tubular bag packaging unit 9, initially in an initial state. It includes an endless roll 50 of a tube 51, from which tubular bags can be produced by transverse welding. The unrolled section passes through two spring-loaded press rollers 52, 53 which roll against each other. At the upper end of the unrolled section, a vacuum strip 54, 55 can be seen on both sides, each with an electrically heatable sealing strip 56 integrated into it.
[0096] From this initial state, the two vacuum bars 54, 55, which suck tightly on both sides of the tubular material 51 and are then moved upwards by a motor, are pressed on while the tubular material 51 is unrolled from the roll 50 and pulled through the two pressing rollers 52, 53, so that the state as shown in FIG. 16 is finally achieved. The pressing rollers 52, 53 can be motor-driven if necessary, torque-controlled if necessary, so that under no circumstances can the mouth of the tubular bag be torn off the vacuum strips 54, 55. In the illustration according to FIG. 12, a tubular section has been pulled up to form a single tubular bag and it is still held in this position by the vacuum bars 54, 55.
[0097] The next step is shown in FIG. 17: Two electrically heatable welding bars 58, 59 with heating strips 57 for welding are moved above the press rollers 52, 53 from both sides to the tubular material 51 and pressed together. The tubular material 51 is then transversely welded at this point, forming a bag from the tubular section that is tightly sealed at the bottom and open at the top.
[0098] What happens next is shown in FIG. 18, where the vacuum pumps 76, 77 for the vacuum bars 54, 55 are shown. The two lower welding bars 58, 59 have already moved apart into the state shown here, and the two upper vacuum bars 54, 55 also move apart a little. As a result, the end areas 60, 61 of the hose material 51 detach from the vacuum bars 54, 55 and their heating or welding bars 56, as indicated by the curved arrows, while one half of the hose width in the middle area remains held in place by the vacuum bars 54, 55. As a result, a square opening 62 of the tubular bag 63 is formed. At the bottom of the tubular bag 63, a welded, band-shaped area 64 extending across the tube 51 can be seen.
[0099] In the next step, as shown in FIG. 19, the tubular bag 63 is cut along the center of this band-shaped area 64 by a cutting device 65 with a cutting blade 66. The cutting blade 66 moves along a beam of the cutting device 65 and its cutting edges 67, which run at an angle to the plane of the tubular material, cut through the tubular bag 51. Meanwhile, the welding beams 58, 59 with their electrically heatable welding bars 57 are moved away from the hose 51 in a translatory manner by their drive.
[0100] Now the bag 63 is held freely suspended by the upper vacuum bars 54, 55. As shown in FIG. 20, the cutting device 65 is also moved away from the tube 51 in a translatory manner and a motorized displaceable support plate 75 is moved underneath the hanging bag 63. The vacuum bars 54, 55 are then moved downwards until the bag 63 stands up loosely on the support plate 75, i.e. is no longer hanging. In this state, a feed tube 68 is lowered from the valve 7 (FIG. 6) arranged above the tubular bag packaging unit 9 a little way into the bag 63, which is held open at the top, and a portion of solid material 69 is dropped into the bag 63.
[0101] The next FIG. 21 shows the tubular bag packaging unit 9 with the filled bag 63 still held open at the top and resting on the support plate 75 after retraction of the feed tube 68 and after insertion of an air tube 70 into the bag 63 from above. The contents of the bag 63 are now removed. FIG. 22 shows the tubular bag packaging unit 9 during the subsequent closing of the upper bag mouth 62 of the bag 63. The vacuum bars 54, 55 move towards each other as indicated by the dotted arrows and clamp the bag mouth 62 between them. FIG. 23 shows the state reached at the end. Now, as required, some air is pumped into the bag 63 via the air tube 70 so that it bulges out to contain an air portion so that it can be reliably floated in the sewer system later. The extent of these bulges in the resulting bag 63 can be controlled via the internal pressure. As soon as a set pressure is reached, the air pump switches off. Or the bag bulge is limited by the extent of the bulges, for example with light barriers 83 on both sides. As soon as the light barriers 83 are interrupted, the air pump stops.
[0102] Finally, the bag is welded at the entry point of the air tube 70, as explained with reference to FIG. 24, and then the air tube 70 is withdrawn upwards from the bag 63. The bag 63 is thus hermetically sealed with its contents and an air portion. In this state, the bag 63 is again firmly clamped at the top and held securely, while it still rests on the support plate 75 at the bottom. The vacuum strips 54, 55 closing around the air tube 70 weld the mouth of the bag with their integrated welding strips 56.
[0103] FIG. 24 shows a solution for how the vacuum strips 54, 55 with their welding bars 56 are designed so that the bag 63 is first welded along the straight welding bar sections 56, while air is then blown into the bag 63 via the air tube 70. The vacuum bars 54, 55 each have a recess 79 in the middle so that they close tightly around the inserted air tube 70. At this recess point, they each extend downwards into a hollow extension 82 towards the air tube 70, into which the mouth 80 of the air tube 70 extends. Curved welding bars 81 extend along the edge of this extension. When the vacuum bars 54, 55 are still retracted and tightly enclose the air tube 70 in their center, the straight sections of the welding bar 56 on both sides of the air tube 70 are first activated to weld the bag 63 and the bag is welded along these welding bar sections. Air can then still be pumped into the bag 63 via the air tube 70 and its mouth 80 until it bulges sufficiently. Only then are the curved welding bars 81 also activated and weld the area of the bag 63 around the opening 80 of the air tube 70. The bag is thus hermetically welded and closed and is still held by the vacuum bars 54, 55.
[0104] The situation as shown in FIG. 25 arises, in which the filled, hermetically sealed bag 63 hangs freely on the two vacuum bars 54, 55 after the support plate 75 has been moved away laterally. In the next step, as shown in FIG. 26, a sliding plate 71 is moved at an oblique angle under the hanging bag 63 and then the vacuum bars 54, 55 are moved apart after ventilation into the position in which they are shown in FIG. 26, and thus they allow the bag 63 to fall, which then slides on this sliding plate 71 into the drain pipe 31 and then into the sewer system, as indicated by the arrows. The drain pipe 31 is equipped here with a spring-loaded odor flap 87 to prevent odors from the sewer system from entering the entire device.
[0105] A particularly advantageous implementation of the bag packaging for producing bags that are rounded at the top and bottom is shown in the following figures. FIG. 27 shows the special arcuate design of the lower sealing bars 83, 84. When a piece of tubular bag material is pulled up from the vacuum bars 55, 54, these two arcuate sealing bars 83, 84 move together as shown by the arrows and clamp the tubular material 51 between them. Next, a weld is made by these two welding bars 83, 84, whereby the tubular bag material 51 is welded at the bottom in an arc-shaped seal. At the same time, the material outside or below the welding beams 83, 84 is cut away by special arc-shaped knife blades on the welding beams 83, 84 and falls downwards into a collecting container, not shown, from which these shreds can be emptied from time to time.
[0106] FIG. 28 shows the situation after the two arcuate welding bars 83, 84 with their electrically heatable welding strips 56 have been moved apart. Here, the lower sealed weld can be recognized with a thick dashed line, so that a bag 63 open at the top has now already been created, as is held open in a square shape by the upper vacuum strips 55, 54, as already described. This figure also shows one of the two curved upper sealing bars 85. After the solids are dropped from the portioning device in this state of the tubular bag 63 and fall into the tubular bag 63, which is held open at the top, it must also be sealed at the top.
[0107] This is shown in FIG. 29. For this purpose, the upper vacuum bars 55, 54 move together and close the upper opening or mouth of the tubular bag 63 around the air tube 70 still projecting into the bag. Now a controlled amount of air is blown into the bag through the air tube 70, so that the bag assumes a desired curved shape bulging to the front and rear. The purpose of the air is to ensure that the finished tubular bag generates sufficient buoyancy in the sewer system so that it floats or at least approximately floats with sufficient buoyancy in the sewer pipes. After this filling with air, the two upper curved welding bars 85, 86 move together as shown by the arrows and clamp the tubular bag 63 between them. The tubular material is then tightly welded and at the same time the excess pieces of film above the welding bars 85, 86 are cut or punched away by the curved blades of knives which extend along the length of the actual electrically heatable welding bars 56 above them. The foil snippets fall into the aforementioned collecting container.
[0108] After the sealing bars 85, 86 have been moved away from the finished tubular bag 63, the situation is as shown in FIG. 30. A tubular bag 63, curved at the top and bottom, with straight edges on both sides and bulging towards the front and rear, contains a defined portion of solids together with a defined amount of air. It is still suspended here between the vacuum strips 55, 54, which were responsible for the welding at the bottom around the lower opening of the air tube 70.
[0109] FIG. 31 shows what now follows. The air tube 70 is pulled upwards a little. After a sliding channel 71 or a sliding plate has been moved under the support plate 75 from below, the support plate 75 is pulled away. The tubular bag 63 is released downwards via this sliding channel 71 or this sliding plate by venting the vacuum bars 55, 54 and then moving them apart into the position shown here. The tubular bag 63 then slides into a collecting pipe 31 and through a spring-loaded odor flap 87, which is pivotably arranged in a housing 88, it falls downwards and finally into the sewage system.
[0110] FIG. 32 shows the design of an arcuate welding bar 83-86. It has an arcuate, electrically heatable welding bar 56, and an arcuate knife 73 with a sharp blade extends parallel to this electric welding bar 56 in the radial direction outside the same. These arcuate blades 73 are advantageously arranged with their rear side in the arcuate welding bar 83-86 so as to be slightly elastically flexible, for example by means of a spring plate arranged underneath or by means of a rubber-elastic profile as shown.
[0111] Finally, FIG. 33 shows the finished welded and punched bag 63 in its final state. Apart from two straight sections, the bag 63 is curved, i.e. almost circular and bulging at the top and bottom. Such bags 63 slide or float along with the wastewater in the sewer system without any problems and finally arrive intact either in a separate collection station for sporadic emptying, or to a sewage treatment plant, where they float in the clarifier and can be removed for further processing.
[0112] FIG. 34 shows a photographically captured tubular bag 63 from a prototype system, with which technical proof was successfully provided that such tubular bags 63 with a proportion of solids in them can actually and easily be produced and can easily be washed along in the sewer system without being damaged.
[0113] Overall, this concept uses much less fresh water and significantly reduces the load on wastewater treatment plants, as the solids are specifically separated from the rinsing water and do not mix with it and then have to be laboriously separated from it again in the wastewater treatment plant.
[0114] The method of disposal of the bags 63 with the solids contained therein can in principle be left open here. It is probably best to recycle them thermally, whereby the heat generated can then be used as process heat, or to treat hot water in decentralized systems.
[0115] This should also be mentioned as an afterthought: [0116] The entire device and all its components are automatically monitored and controlled by a PLC controller with computer 18, which controls all the functions described. [0117] The device preferably includes remote monitoring so that any faults are immediately detected and indicated by a visual and audible alarm, or such a message can be transmitted via an electronic network or via the Internet to the smartphones of the occupants of the building and/or a service company. For example, it can be used to indicate when the roll 50 of tubular film material 51 is running low and will soon need to be replaced by a new roll. When the roll is used up, the tubular bag packaging unit 9 is stopped so that no more solid encapsulation is possible until the new roll 50 in the form of a replacement cassette 10 (FIG. 4) is installed ready for operation. Until this is completed, the rotary valve 21 switches to direct discharge into the sewage system and the toilet 100 is used conventionally. [0118] In the case of domestic or residential depots 117 (FIG. 3), their fill level is monitored and also reported to the residents or directly to a disposal service provider, who assumes responsibility for ensuring that these depots 117 are always emptied in good time and always have sufficient free capacity. If the fill level reaches an adjustable maximum, the tubular bag packaging unit 9 is blocked so that no further bag disposal is possible, but instead the rotary valve 21 is switched to direct discharge into the sewer system and the toilet can be used conventionally. [0119] Because the device can be housed as a complete unit in an installation module 1, it can ideally be designed so compactly that it can also be connected to existing toilets as an optional replacement solution. In contrast to the conventional toilets already installed, the discharge of the hermetically packed bags 63 must be ensured by a separate supply line and inlet into the existing drain pipe. Otherwise, the entire installation module fits into the standardized installation bays for the installation of cisterns in wall-mounted WCs. [0120] The facility significantly reduces the burden on public sewage treatment plants, which is very much welcomed by the wastewater industry. [0121] Depending on the post-treatment or further treatment of the excrement encapsulated in pillow-shaped bags 63, there is the possibility of a sensible further use of the excrement. [0122] The system or concept with this facility offers the option of using standard toilet bowls from well-known manufacturers. [0123] Installation in frame elements (Duo Fix) with the specified connection dimensions can be used for the built-in modules and also for standard WC bowls. [0124] The serviceable part of the system, i.e. installation module 1, can be replaced as a unit (slide-in module). [0125] The operation of this facility does not result in any additional costs compared to the conventional disposal system-on the contrary, it can ultimately be more cost-effective overall compared to the current disposal system. [0126] The device is odorless, as it is completely hermetically sealed. [0127] The device can be operated by an operator with minimal effort and comfort. A replacement cassette with a new roll 50 of hose material 51 simply needs to be inserted from time to time. [0128] Optionally, LEDs and webcams can be installed inside the solids separation tank 3 and the solids tank 5 arranged at the top, as well as inside the tubular bag packaging unit 9, so that the processes in the individual components can be tracked from the outside on a screen or control panel 20 as required, and any faults can thus be inspected and analyzed without having to open anything. [0129] If necessary, film clips can be sent to a service center so that they know immediately what needs to be done. [0130] The bags 63 and, optionally, the accumulated urine are drained into a specially installed pipe system in the building and removed. [0131] This installation can be realized as a modular box with commercially available dimensions, such as the current lightweight systems from Geberit (Duofix & GIS) or Nussbaum (Optivis-Tec) or Grohe Germany. The standard width for wall installation is 500 mm or 750 mm, the height is variable and can be 1120 mm, for example, and the depth approx. 280 mm. These standard dimensions are the same for all other suppliers. This means that it is possible to connect and operate any type of WC with a corresponding module for this installation.
