Abstract
The following abstract of the invention concerns the development of a filtration system applied to agricultural sprayers so that the operator does not come into contact with residues from the applied product, having a cooperative system of a filtering element (14) and a settling filter (36), where the system is managed by an electronic module (41), having obstruction sensors that indicate the need for self-cleaning and recommend the time it should be replaced.
Claims8
1- A SELF-CLEANING FILTRATION SYSTEM APPLIED TO AGRICULTURAL SPRAYERS so that the operator does not come into contact with residues from the applied product, characterized by having a cooperative system of a filter element (14) and a settling filter (36), where the system is managed by an electronic module (41), using a casing (1), containing a settling compartment (33) with a lid (4) and an open/close clamp (40) to maintain the settling filter (36), a compartment (34) of the filtering element (14) provided with a lid (35) to maintain the self-cleaning element (14), said box (1) also containing at its base an inlet for the fluid to be filtered (37), an outlet for pesticide control (38) and an outlet for the settling filter and for subsequent return to the reservoir (39).
2- A SELF-CLEANING FILTRATION SYSTEM APPLIED TO AGRICULTURAL SPRAYERS according to claim 1 and characterized by the existence, inside the compartment (34) of a filtering element (14), a supporting cylinder (11), and inside this supporting cylinder (11) the fluid diffuser (15) and the filtering element (14) are seated, and this supporting cylinder (11) is secured by a fixing handle (18) and by a fixing spindle (17), and said handle (18) can tilt, releasing the cylinder head (16) and, consequently, the filtering element itself (14).
3- A SELF-CLEANING FILTRATION SYSTEM APPLIED TO AGRICULTURAL SPRAYERS according to claim 2 and characterized by the filtering element (14) being composed of internal vanes (65) and external vanes (66) that are held in grooves present on the flanges (63 and 64), where said flanges (63 and 64) (Patent 870170081021, dated Oct. 23, 2017, page 16/36 2/3) are attached to the upper and lower fixers (67), and a 150μ cylindrical mash (68) is arranged around it.
4- A SELF-CLEANING FILTRATION SYSTEM APPLIED TO AGRICULTURAL SPRAYERS according to claim 3 and characterized by the filtering element (14)| being controlled by an electronic module (41) containing an IHM outlet connector (42) and another connector (43) that is connected to the valves (44, 45, 46, and 47), and said module also controls the primary pressure transducer (48) and the secondary pressure transducer (49), and it is also possible to see the inlet for the fluid to be filtered (37), the outlet for pesticide control (38), and the outlet (50) for the settling filter (36).
5- A SELF-CLEANING FILTRATION SYSTEM APPLIED TO AGRICULTURAL SPRAYERS according to claim 4 and characterized by the electronic module (41) allowing three outlets, one of them for connection to the spray shutdown sensor (51), another for connection to the HMI unit (52) and the other (53) connected to fittings connected to the equipment battery.
6- A SELF-CLEANING FILTRATION SYSTEM APPLIED TO AGRICULTURAL SPRAYERS according to claim 5 and characterized by the filtering element (14) having a fluid outlet for settling filtration (54), a filter outlet (55) and a fluid inlet (56) at the upper part of the filter (14).
7- A SELF-CLEANING FILTRATION SYSTEM APPLIED TO AGRICULTURAL SPRAYERS according to claim 6 and characterized by the settling filter (36) containing rigging (57) to be tied to the end of the flange (58).
8- A SELF-CLEANING FILTRATION SYSTEM APPLIED TO AGRICULTURAL SPRAYERS according to claim 1 and characterized by the supply unit (UA) being composed of a three-way valve (69), which receives, connected to it, an adapter (71) and two terminals (72 and 73), with the adapter (71) connected to a flow meter (70) and the terminal (73) connected to a nut (75) that secures this terminal (73) to the housing (76), which is closed by screws (74), in such a way as to expose the terminals (72 and 73), the terminal (79) of the flow meter (70) and the connector (77) with the cable and its connector (78) in the electronic unit.
