DETAILED DESCRIPTION

[0052] FIG. 1 shows a schematic representation of an embodiment of the system 100 for pulp processing and resupply of production-quality pulp 160 to at least one fiber molding system 200, wherein the system 100 is constructed in scalable modular form. Here, a supply module 110 is arranged between two process modules 120. The supply module 110 comprises the machines 112 necessary for the operation of the system, such as for example pumps etc. and infrastructure supply units 114, such as for example water, power, compressed air, gas, data cables etc., or controls components of the process modules 120. In contrast, the process modules 120 are there to reprocess and/or resupply and then provide the pulp. In the system, the supply module 110 and the process modules 120 are equipped with a plurality of interfaces 150, matched to one another in each case, in order to connect supply and process modules 110, 120 to one another, in order to guarantee the infrastructure supply of the process modules 120 and to receive the pulp or the constituents and starting materials thereof via at least one inlet 130 and to transport them between the process modules 120, and to provide the production-quality pulp 160 via an outlet 140 for use by at least one fiber molding system 200. For this, the interfaces 150 are implemented at least partially according to the plug-socket principle. All interfaces 150 are possibly implemented according to the plug-socket principle. As can be seen, the number of interfaces exceeds the number necessary for the operation of this system, which makes a later extension of the system at any time possible since the modules 110, 120 to be added later can be supplied via the free interfaces or connected to other modules 110, 120. Here, the outlet 140 is designed as a multiple outlet and can be matched to the throughput of pulp of the connected fiber molding systems 200 via a corresponding controllable valve 145. The system 100 can thus be operated such that it continuously provides a minimum amount of pulp at the outlet 140 to be taken off by the connected fiber molding system 200. Furthermore, the system 100 is designed and controlled so as to be operated in a continuous mode at the inlet 130 and at the outlet 140, with the result that a continuous amount of starting material for the pulp is taken off at the inlet 130 and a continuous amount of production-quality pulp is provided at the outlet 140. Furthermore, the system 100 is provided so as to permit, in a continuous mode, a material flow varying between a minimum amount and a maximum amount at the inlet 130 and/or at the outlet 140, without the continuous material flow at the inlet 130 and at the outlet 140 being interrupted. Since the system 100 in the process module or modules 120 is operated in a so-called batch process, for this it comprises one or more buffer tanks in the process modules 120. In this case, the process modules 120 are here equipped with the processing tank 3 and the buffer tanks 5 and 12. Here, the supply modules 110 and process modules 120 can be implemented as mobile containers.

[0053] FIG. 2 likewise shows a schematic representation of another embodiment of the system 100 for pulp processing and resupply of production-quality pulp 160 to at least one fiber molding system 200, wherein this system 100 is also constructed in scalable modular form. Here too, the supply module 110 is arranged as central module, wherein the several process modules 120 are arranged around the supply module 110. In FIG. 2, in contrast to FIG. 1, the supply module 110 is composed of two sub-modules 110a, 110b, in order to be able to operate the process modules 120 (in a greater number here than in FIG. 1) accordingly. Here, the sub-modules 110a, 110b can fulfil different supply tasks, for example, for which purpose they are correspondingly equipped with a different number of machines 112. For the further components not explained in detail here, reference is made to the statements regarding FIGS. 1 and 3. In the process modules, here in FIG. 2 the processing tanks 3, 6, 7, 8 and 11 and the buffer tanks 5, 9, 10, 12 as well as a water tank 4 are shown by way of example. Here, the tanks 1-12 are likewise only shown as an illustration of the pulping process. For a more detailed explanation of the functions of the tanks 1-12 shown here, reference is made to FIG. 3.

[0054] FIG. 3 shows a schematic representation of the scalability of the system 100 according to the disclosed embodiments. Different systems 100 can comprise different modules, which manifests itself in the different equipping with the tanks 1-13. Here, the equipping with the tanks 4, 8, 11 and 13, for example, can also be optional. As the modules 110, 120 comprise a large number of interfaces 150, matched to one another in each case, which exceeds a minimum number of necessary interfaces 150 in a basic configuration (for example the top configuration with the tanks 3-5 and 12-13), a free scalability of the system 100 remains guaranteed at all times, as is shown by the four different system types 100. The components or tanks 1-13 shown have the following functions:

[0055] Component 1 denotes a weighing machine for the entering cellulose or fiber pulp material as starting material for producing the fibrous material. The weighing machine acts as inlet 130 for the cellulose or fiber pulp material. Component 2 denotes a tank with a tilting-lever device for pouring the fiber pulp material into the tank 3, which acts as a so-called pulper, where a first mixture of solvent with fiber pulp material is produced or made up. Tank 4 denotes a water tank. Tank 5 denotes a buffer tank, tank 6 denotes a centrifuge for a fiber concentration of more than 8 wt.-% (percent by weight), in which the material present can be separated according to weight. In the pulp, tanks 7 and 8 denote a grinder for conditioning the fibrous material or a deflaker, in which small agglomerates of fibrous material can be separated or dissolved. Tanks 9 and 10 denote buffer tanks, in which additives are added. Tank 11 denotes a rotary sifter. Tank 12 likewise denotes a buffer tank and tank 13 again denotes a centrifuge, here for a fiber concentration of approximately 1 wt.-% (percent by weight).

[0056] FIG. 4 shows a tank 1-13 of the system 100 according to the disclosed embodiments with sloping base B in lateral section. Tank 1-13 has a base B with a slope, here in the direction of the right-hand edge R of the tank 1-13. In other embodiments, the edge can also be arranged on another side of the tank. A reversibly sealable cleaning opening RO is arranged on this edge R. Here, the slope is implemented continuously in that the base B is a planar sloping surface. As slope, the base B can have an angle α relative to the horizontal H between 2 degrees and 10 degrees. This angle is preferably 3 degrees.

[0057] FIG. 5 shows a schematic representation of a fiber molding system 200 according to the disclosed embodiments comprising a system 100 for pulp processing and resupply of production-quality pulp 160 to a pulp reservoir 210 of the fiber molding system 200 as well as a return line 220 from the reservoir 210 to the system 100 for processing the used pulp.

[0058] FIG. 6 shows a schematic representation of a method 300 according to the disclosed embodiments for the construction of the system 100 according to the disclosed embodiments for pulp processing and resupply of production-quality pulp 160 to at least one fiber molding system 200, comprising the steps of providing 310 a supply module 110, which comprises or at least controls the machines 112 and infrastructure supply units 114 necessary for the operation of the system 100; providing 320 one or more process modules 120, in which the pulp is reprocessed and/or produced for resupply and then provided; and connecting 330 the supply module 110 to the process module or modules 120 via the plurality of interfaces 150, matched to one another in each case, of the supply and process modules 110, 120, in order to guarantee the infrastructure supply of the process modules 120, in order that the pulp or the constituents and starting materials thereof can be received via at least one inlet 130 and can be transported between the process modules 120 for processing or resupply, and the production-quality pulp 160 can be provided via an outlet 140 for use by at least one fiber molding system 200.

[0059] FIG. 7 shows a schematic representation of a method 400 according to the disclosed embodiments for extending the system 200 according to the disclosed embodiments for pulp processing and resupply of production-quality pulp 160 to at least one fiber molding system 200, comprising, utilizing a scalable modular form of the system 100, the following steps of connecting 410 the process modules 120 needed for the extension to the still free interfaces 150 of the already present process and supply modules 110, 120; and of operating 420 a system 100 extended in this way for pulp processing and resupply of production-quality pulp 160 to at least one fiber molding system 200. Here, the method 400 can comprise the further step of adding and connecting 430 at least one further supply module 110 to the already present process and supply modules 110, 120 via the still free interfaces 150 of the already present process and supply modules 110, 120.
