Self-cleaning filtration system for use in agricultural sprayers

A self-cleaning filtration system applied to agricultural sprayers, comprising:

• a filter element (14);
• a settling filter (36);
• a casing (1) adapted to receive a settling compartment (33) with a lid (4);
• and
• an open/close clamp (40) adapted to maintain the settling filter (36), wherein a filter element compartment (34) of the filter element (14) is provided with a lid (35) to maintain the filter element (14), wherein said casing (1) includes an inlet for a fluid to be filtered (37), an outlet for pesticide control (38) and an outlet for the settling filter (36) and for subsequent return to a reservoir (39);
• wherein the filter element compartment (34) of the filter element (14) has a supporting cylinder (11) provided inside the filter element compartment (34),
• the filter element compartment (34) of the filter element (14) further includes a fluid diffuser (15), wherein the filter element (14) and the fluid diffuser (15) are seated inside the supporting cylinder (11), wherein the supporting cylinder (11) is secured by a fixing handle (18) and a fixing spindle (17), wherein the fixing handle (18) is adapted to tilt to release a cylinder head (16) and the filter element (14),
• wherein the filter element (14) is provided with internal vanes (65) and external vanes (66) that are held in grooves formed on first flanges (63, 64) of the filter element (14), wherein the first flanges (63, 64) are attached to upper and lower fixers of the filter element (14), the filter element (14) further includes 150μ cylindrical mash (68) arranged around the filter element (14),
• wherein the filter element (14) is controlled by an electronic module (41) having a IHM outer connector (42) and another connector (43) connected to valves (44, 45, 46, 47) provided in the system, wherein the electronic module (41) controls a primary pressure transducer (48), and a secondary pressure transducer (49), wherein the inlet for the fluid to be filtered (37), the outlet for pesticide control (38), and the outlet (50) for the settling filter (36) are visible on the casing (1);
• wherein the electronic module (41) is provided with three second-outlets and is configured to control the outlets, wherein one second-outlet being connected to a spray down sensor (51), another second-outlet being for connection to a HMI unit (52) and other second-outlet being connected to an equipment battery;
• wherein the filter element (14) having a fluid outlet for settling filtration (54), a filter outlet (55) and a fluid inlet (56) at an upper part of the filter element (14);
• wherein the settling filter (36) containing rigging (57) to be tied to an end of a second flange (58) of the filter element (14);
• and
• wherein the system further includes a supply unit (UA) having a three-way valve (69) adapted to receive an adapter (71) and two first terminals (72 and 73), wherein the adapter (71) is connected to a flow meter (70), and a first one of the two first terminals (73) is connected to a nut (75) that secures the first one of the two first terminals (73) to a housing (76), which is closed by screws (74), in such a way as to expose the two first terminals (72 and 73), and a second terminal (79) of the flow meter (70).
