Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a pre-pump mesh swirl jet power filter. Background Technology

[0002] With the rapid development of water-saving irrigation technology in farmland, the technical requirements for irrigation filters are becoming increasingly stringent. To improve the filter's effectiveness in treating poor water quality containing large amounts of silt, willow catkins, floating leaves, and plankton, and to automatically clean up clogged impurities during filtration, a pre-pump mesh cyclone dynamic filter is typically used.

[0003] A search revealed Chinese patent number CN221933227U, which proposes a pre-pump mesh-type swirl jet power filter, comprising a filter structure mounted on a bracket; a self-cleaning structure disposed inside the filter structure and rotatably connected to the filter structure; and a swirl jet structure coaxially mounted on one side of the filter structure, which drives the self-cleaning structure to rotate, and the swirl jet structure is connected to the self-cleaning structure.

[0004] In the aforementioned patent, the filtration cycle and cleaning cycle can be performed simultaneously, reducing filtration and cleaning time and improving filtration efficiency. It can automatically clean the impurities clogging the filter. However, the self-cleaning structure is simple. When the rotating mechanism sprays water to clean the impurities clogging the filter cartridge, the pump body draws liquid for filtration and then adsorbs the impurities on the filter cartridge inward. This makes it impossible to clean the impurities on the filter cartridge completely, thus reducing the cleaning effect on the filter cartridge. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a pre-pump mesh-type swirl jet power filter, comprising:

[0028] The filter frame 11 has an inner wall with a rotatable outer filter cylinder 12. One end of the outer filter cylinder 12 is rotatably connected to a pump body 13. The outer wall of the filter frame 11 is fixedly provided with a scraper 15, and one end of the scraper 15 is in contact with the outer wall of the outer filter cylinder 12.

[0029] The water inlet pipe of the pump body 13 passes through the filter frame 11, and one end of it is rotatably connected to one end of the filter outer cylinder 12. The scraper plate 15 is used to scrape off impurities on the filter outer cylinder 12. The scraper plate 15 is set horizontally.

[0030] The rotating component includes a first bearing 21 and a gear ring 24. The upper and lower ends of the first bearing 21 are respectively fixedly disposed on the inner wall of the filter outer cylinder 12. A connecting shaft 22 is fixedly disposed on one side of the first bearing 21. A rotating fan blade 23 is fixedly disposed on one end of the connecting shaft 22. One side of the gear ring 24 is fixedly disposed on the other end of the filter outer cylinder 12. A first transmission gear 25 is meshed on the tooth edge of the gear ring 24. A second transmission gear 26 is meshed on the bottom end of the first transmission gear 25.

[0031] The rotating fan blade 23 is used to drive the outer filter cylinder 12 to rotate. The gear ring 24 does not contact the inner wall of the filter frame 11. The first transmission gear 25 is used to provide driving force so that the gear ring 24 and the second transmission gear 26 rotate in opposite directions.

[0032] A water spray component is installed inside the outer filter cylinder 12 and is connected to the outer filter cylinder 12 via a rotating component;

[0033] The water spray component is used to spray water outward to rinse the outer filter cylinder 12.

[0034] The water spraying component includes a water spray pipe 31. The outer wall of the water spray pipe 31 is fixedly installed on the inner wall of the second transmission gear 26. Several high-pressure nozzles 32 are connected to the top of the outer wall of the water spray pipe 31. One end of the water spray pipe 31 is rotatably connected to a water collection plate 33. The top of the water collection plate 33 is connected to a guide pipe 34. One end of the guide pipe 34 is connected to the top of the water inlet pipe of the pump body 13.

[0035] Several high-pressure nozzles 32 are equidistantly arranged, and the guide pipe 34 is used to transport part of the filtered water to the spray pipe 31.

[0036] The rotating component also includes a second bearing seat 27, with both ends of the second bearing seat 27 fixedly mounted on the inner wall of the water inlet pipe of the pump body 13, and the outer wall of the connecting shaft 22 penetrating through the second bearing seat 27;

[0037] The second bearing seat 27 is rotatably engaged with the connecting shaft 22. The second bearing seat 27 is used to connect the connecting shaft 22 for rotation, thereby improving the overall stability when the connecting shaft 22 rotates.

[0038] The rotating component also includes a support shaft 28, one end of which is fixedly connected to the inner wall of the first transmission gear 25, and the other end of which is rotatably connected to the inner side wall of the filter frame 11.

[0039] The support shaft 28 is used to support the rotation of the first transmission gear 25, thereby ensuring stable meshing and transmission between the first transmission gear 25, the gear ring 24, and the second transmission gear 26.

[0040] The outer walls of the water spray pipe 31 pass through one side of the filter frame 11 and the other end of the filter outer cylinder 12, respectively.

[0041] The water spray pipe 31 is rotatably engaged with the filter frame 11 and the outer filter cylinder 12.

[0042] Working principle: The filter is placed in the water body. The pump body 13 pumps water and filters it through the outer filter cylinder 12. The filtered impurities adhere to the outer filter cylinder 12. Part of the filtered water pumped by the pump body 13 is used for irrigation, and the other part enters the water collection tray 33 through the guide pipe 34. From the water collection tray 33, it is transported to the spray pipe 31 and sprayed outward through the high-pressure nozzle 32. At the same time, the filtered water pumped by the pump body 12 passes through the rotating fan blade 23. Under the action of the water flow, the rotating fan blade 23 rotates. The rotation of the rotating fan blade 23 drives the first shaft seat 21 to rotate through the connecting shaft 22. The filter outer cylinder 12 is rotated, which in turn drives the gear ring 24 to rotate. This rotation, in turn, drives the second gear 26 to rotate in the opposite direction via the first transmission gear 25. The rotation of the second transmission gear 26 drives the water spray pipe 31 to rotate and spray water, thereby clearing the impurities clogging the filter outer cylinder 12. When the impurities on the filter outer cylinder 12 come into contact with the scraper 15, they are scraped off by the scraper 15. Through the opposing rotation of the water spray pipe 31 and the filter outer cylinder 12, and with the cooperation of the scraper 15, the impurities on the filter outer cylinder 12 can be cleaned, thereby improving the cleaning effect of the filter cylinder.

[0043] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment.

[0044] One end of the outer filter cylinder 12 is fixedly provided with an inner filter cylinder 14;

[0045] The inner filter cylinder 14 can perform secondary filtration.

[0046] A cleaning brush 35 is fixedly installed at the inner top of the water spray pipe 31, and the bottom end of the cleaning brush 35 contacts the outer wall of the filter inner cylinder 14.

[0047] The cleaning brush 35 is used to clean the outer wall of the filter inner cylinder 14.

[0048] Working principle: When the pump body 13 draws liquid, the water will pass through the outer filter cylinder 12 and the inner filter cylinder 14 in succession. The two filter cylinders improve the filtration effect of the water. At the same time, when the filtered water drives the outer filter cylinder 12 to rotate through the rotating fan blade 23, it also drives the cleaning brush 35 to rotate through the water spray pipe 31, so that the cleaning brush 35 cleans the outer wall of the inner filter cylinder 14 and prevents it from becoming blocked.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
