DETAILED DESCRIPTION

[0028] The multiple filtering device is composed of 83 items including parts and components as can be seen in the figures and will be detailed below.

[0029] The filtering elements of the multiple filtering device (1 to 3) are mounted concentrically on the lid (9) in the sequence EF1 (1), EF2 (2) and EF3 (3) with mesh sizes of different microns arranged concentrically, that is, they are staggered in such a way that a smaller filtering element is surrounded by a larger filtering element with the formation of an intermediate space between the casing, a filtering element and another called filtering chambers, forming four filtering chambers which called multiple filtering.

[0030] The multiple filtering device has the function of retaining the solid particles of the fluid more efficiently, avoiding any possibility of obstruction in the spray nozzles.

[0031] The lid (7 to 10) has the function of coupling the filtering elements and seals (1 to 6) and closing the body of the device (68). The junction of the cover (09) with the body (68) forms the device's chamber. The junction of the lid (09), the body (68) and the filtering elements (01 to 06) form the four chambers of the device.

[0032] The waste discharge valves (11 and 12) are attached to the lid (9), with three valves (one for each chamber) having the function of expelling the accumulated residues in the filter element chambers (1 to 03).

[0033] Handle to lock and unlock the lid (13 to 18), where the handle facilitates the locking and unlocking of the lid without the need for the aid of tools for the same. The ring (13) seals the lid (9) and the spindle bushing (14), the ring (15) seals the spindle, spindle bushing (14) and the spindle (16), the spindle is coupled to the lid bearing (46). The locking pin (18) has a locking/unlocking device in a drive button to facilitate the decoupling of the cover (09) in case of need for cleaning, the same makes the fit between the crank (17) and the spindle (16).

[0034] Safety lock system (19 to 23, 38, 40 and 49) when the threaded sleeve (7) and the central rod (72) are uncoupled, the lid (9) is unlocked and the stop (49) is engaged to the trigger (21) limiting the sudden fall of the lid (9), to lower the lid it is necessary to press the trigger button (38).

[0035] Indexing disk (24, 25, 30 to 35) lid centering function (9) with central rod (72). The spring (32) compresses the indexing pin (31) against the indexing disk (24), the indexing disk has a channel in which, aligned with the roller (35), it reaches the locking point of the cover (09).

[0036] Lid lift (26 to 29, 36, 37) has the function of lowering the lid safely to clean the filtering elements, when necessary, and raising the lid to lock it.

[0037] Lid rod (39 to 51) lid rod assembly (39), guide roller (43), guide roller with groove (42), guide roller spacers (41), cover bearing (46), guide rod (48) and the guide rod pivot bushing (47) allow lateral displacement of the lid to remove the filtering elements.

[0038] The lid lifting cable (51) at one end is fixed to the base of the body (76), its other end is fixed to the cable holder (28), its segment passes through the guide roller with channel (42) and when turning the crank (37) the cable will wind on the reel (26).

[0039] Inlet and outlet system (52 to 56), where the fluid passes from the pump to the multiple filtering device through the inlet and outlet connection and from the system to the spray equipment segments.

[0040] In the event of obstruction of the filtering elements, the device has a relief valve (60 to 67) that prevents the device from having excess pressure by diverting excess fluid from the body of the device (68) through the return to the spray tank. The relief valve needle (67) has holes with the function of passing fluid to an antechamber between the needle and the relief valve spring tensioner (64), in order to dampen the relief valve needle (67) making it stabilize the work of the valve, avoiding vibration. Also, it has a relief valve adjustment handle (63) for regulating the working pressure limit of the system.

[0041] Body of the multiple filtering device (68) with the lid junction (9) and the filtering elements (1 to 6) form four filtering chambers in the device. Accommodates the central rod (72) which has the function of locking the lid (09), audio sound pressure switch (69.1) with the function of monitoring the obstruction of the device and alerting, through audible and visual signal (82, 83), the need device cleaning.

[0042] Vision pressure switch (69.2), when the operator activates the spray pump, it will cause a pressure in the system which will activate the pressure switch activating all the electronic components for the operation of the system, not requiring manual activation, in the same way when the operator turns off the spray pump, the lack of pressure will shut down the system.

[0043] Pressure transducers (77) reads the system pressure and transmits data to the monitor (79).
