[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Please refer to Figure 1-7As shown, this utility model provides an agricultural irrigation filter, including a base 1. A main filter 3 and a secondary filter 5 are installed on the top of the base 1. A first cover 4 and a second cover 6 are respectively installed on the top of the base 1. An inlet pipe 7 is installed on the top of the first cover 4. An outlet pipe 8 is installed on the bottom of the main filter 3. An inlet water pipe 9 connected to the inlet pipe 7 is installed on the top of the second cover 6. An outlet water pipe 10 connected to the outlet pipe 8 is installed on the bottom of the secondary filter 5. A valve 11 is installed on one side of the inlet pipe 7, the outlet pipe 8, the inlet water pipe 9, and the outlet water pipe 10. Filter cartridges 15 are connected to the inner sides of the main filter 3 and the secondary filter 5 through a snap-fit mechanism that is easy to disassemble and assemble. A multi-stage filtration mechanism is detachably installed on the inner side of the filter cartridge 15.
[0025] Specifically, irrigation water enters the filter through the inlet pipe 7, which is equipped with a valve 11 to control the flow and volume of water. The diversion design of the main filter 3 and the auxiliary filter 5 allows for flexible adjustment of the filter's operating status according to actual irrigation needs, facilitating maintenance during operation. The multi-stage filtration mechanism installed inside the filter cartridge 15 effectively removes various impurities from the water, ensuring the cleanliness of the irrigation water. The filter cartridge 15 is connected to the main filter 3 and the auxiliary filter 5 via a snap-fit mechanism, making cleaning or replacing the filter cartridge 15 and its internal multi-stage filtration mechanism simple and convenient. This structure effectively improves the filter's filtration accuracy and ensures its filtration effect, while also facilitating cleaning and maintenance, greatly enhancing operational convenience.
[0026] The multi-stage filtration mechanism includes a coarse filter 28, a fine filter 29, and an activated carbon filter layer 30. Three sets of retainers 27 are arranged from top to bottom on the inner side of the filter cylinder 15. The coarse filter 28, fine filter 29, and activated carbon filter layer 30 are respectively placed inside the three sets of retainers 27. The coarse filter 28 is typically made of stainless steel and has large mesh openings to intercept larger particles of impurities in the water. The fine filter 29 uses high-precision filter material to filter out even finer particles, further improving the purity of the water. The activated carbon filter layer 30 utilizes the adsorption properties of activated carbon to remove organic matter, odors, and some heavy metal ions from the water, improving the quality of irrigation water and providing a better water source for crops. This design effectively improves the filtration precision of the filter and ensures its filtration effect.
[0027] The filter cartridge 15 has a cover plate 26 on one side. Two sets of first fixing plates 31 are symmetrically arranged on the outer ring of the filter cartridge 15. Second fixing plates 35 are provided at both ends of the cover plate 26. A first through groove 32 is opened on one side of each of the two sets of first fixing plates 31. A lead screw 33 is rotatably connected to the inner side of each of the two sets of first through grooves 32 and a locking cap 34 is threaded onto it. A second through groove 36, adapted to the lead screw 33, is opened on one side of each of the two sets of second fixing plates 35. The second fixing plates 35 at both ends of the cover plate 26 are aligned with the first fixing plates 31 on the outer ring of the filter cartridge 15, so that the second through groove 36 aligns with the first through groove. The positions of 32 correspond, and then, by rotating the two sets of lead screws 33 and making them pass through the second through groove 36, and then by rotating the locking cap 34, it is rotated along the thread of the lead screw 33. As the locking cap 34 rotates, the lead screw 33 is gradually tightened, and the distance between the first fixing plate 31 and the second fixing plate 35 gradually decreases until the cover plate 26 is tightly attached to the filter cartridge 15. At this time, stop rotating the locking cap 34 to complete the installation and fixing of the cover plate 26. In this way, the coarse filter screen 28, the fine filter screen 29 and the activated carbon filter layer 30 can be easily disassembled, cleaned and maintained.
[0028] The locking mechanism includes a locking block 24. Two sets of mounting seats 12 are symmetrically installed near the top of the inner walls of the main filter 3 and the auxiliary filter 5. Each set of mounting seats 12 has a fixed shaft 16 at its top, and a fixed boss 17 at its end. A movable boss 18, opposite to the fixed boss 17, is slidably connected to the outer ring of the fixed shaft 16. An abutment ring 20 is fitted around the outer ring of the movable boss 18, and the abutment ring 20 is connected to the mounting seat 12 via four sets of first springs 19. A mounting plate 13 is fitted near the top of the outer ring of the filter cartridge 15, and two sets of handles 14 are installed on its top. Two handles are symmetrically opened at the bottom of the mounting plate 13. The movable groove 21 has two sets of sliding grooves 22 symmetrically formed on its inner wall. Each set of sliding grooves 22 has a fixed rod 23 on its inner side, slidably connected to a locking block 24. One side of the locking block 24 is connected to one side of the inner wall of the sliding groove 22 via a second spring 25 sleeved on the outer ring of the fixed rod 23. One end of the locking block 24 is sloped. When installing the filter cartridge 15, by pushing the mounting plate 13 towards the mounting base 12, the fixed shaft 16 and the fixed boss 17 can penetrate the inner side of the movable groove 21. While the mounting plate 13 is continuously pressed, the two sets of locking blocks 24, through their contact with the fixed boss 17, can move into the inner side of the two sets of sliding grooves 22. Lateral movement allows both sets of locking blocks 24 to simultaneously compress the two sets of second springs 25. When the two sets of locking blocks 24 move to one side of the fixed boss 17, the reaction force of the two sets of second springs 25 drives the two sets of locking blocks 24 to move towards the center position, allowing the two sets of locking blocks 24 to pass through one side of the fixed boss 17. Then, through the action of the abutment ring 20 and the four sets of first springs 19, the two sets of locking blocks 24 can be abutted and fixed to the fixed boss 17, thus completing the installation and fixing of the mounting plate 13 and the filter cartridge 15. When it is necessary to disassemble and remove the filter cartridge 15, by continuing to press the mounting plate 13, the mounting plate 13... The two sets of locking blocks 24 can be moved to one side of the movable boss 18. When the mounting plate 13 loses its pressing force, under the action of the reaction force of the contact ring 20 and the four sets of first springs 19, the mounting plate 13 and the corresponding two sets of locking blocks 24 can be moved upward. The two sets of locking blocks 24 can move the movable boss 18 upward. When the movable boss 18 abuts against the fixed boss 17, the two sets of locking blocks 24 can slide upward along the movable boss 18 and disengage from the fixed boss 17, thereby completing the disassembly and removal of the mounting plate 13 and the filter cartridge 15. Thus, by setting up the system, the disassembly, assembly, cleaning and maintenance of the filter are facilitated, and the ease of operation is greatly improved.
[0029] The base 1 has two sets of mounting holes 2 on each of its two sets of support legs. The mounting holes 2 allow for easy installation and fixation of the device.
[0030] Working principle: First, when disassembling and assembling the filter cartridge 15, by pushing the mounting plate 13 towards the mounting base 12, the fixed shaft 16 and the fixed boss 17 can pass through the inner side of the movable groove 21. While the mounting plate 13 is continuously pressed, the two sets of locking blocks 24 can move towards the inner side of the two sets of sliding grooves 22 through the abutment action with the fixed boss 17. At the same time, the two sets of locking blocks 24 can compress the two sets of second springs 25. When the two sets of locking blocks 24 move to one side of the fixed boss 17, under the action of the reaction force of the two sets of second springs 25, the two sets of locking blocks 24 can be driven to move towards the center position, so that the two sets of locking blocks 24 can pass through one side of the fixed boss 17. Then, under the action of the contact ring 20 and the four sets of first springs 19, the two sets of... The locking block 24 abuts against the fixed boss 17, thereby completing the installation and fixing of the mounting plate 13 and the filter cartridge 15. When it is necessary to remove the filter cartridge 15, by continuing to press the mounting plate 13, the mounting plate 13 can drive the two sets of locking blocks 24 to one side of the movable boss 18. When the mounting plate 13 loses the pressing pressure, under the action of the reaction force of the contact ring 20 and the four sets of first springs 19, the mounting plate 13 and the corresponding two sets of locking blocks 24 can be driven to move upward. The two sets of locking blocks 24 can drive the movable boss 18 to move upward. When the movable boss 18 abuts against the fixed boss 17, the two sets of locking blocks 24 can slide upward along the movable boss 18 and disengage from the fixed boss 17, thereby completing the removal of the mounting plate 13 and the filter cartridge 15.
[0031] When disassembling and assembling the multi-stage filtration mechanism, align the second fixing plates 35 at both ends of the cover plate 26 with the first fixing plate 31 on the outer ring of the filter cartridge 15, so that the second through groove 36 corresponds to the first through groove 32. Then, rotate the two sets of lead screws 33 and make them pass through the second through groove 36. Then, rotate the locking cap 34 to make it rotate along the thread of the lead screw 33. As the locking cap 34 rotates, the lead screw 33 is gradually tightened, and the distance between the first fixing plate 31 and the second fixing plate 35 gradually decreases until the cover plate 26 is tightly attached to the filter cartridge 15. At this time, stop rotating the locking cap 34 to complete the installation and fixing of the cover plate 26 and the multi-stage filtration mechanism. By reversing the operation, the disassembly and maintenance of the multi-stage filtration mechanism can be conveniently carried out, thus completing the entire operation process.
