Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This utility model embodiment provides a microfilter with fish backwashing function, including a top plate 1, exemplarily, such as... Figure 1 , Figure 2 and Figure 4As shown, a base 2 is located directly below the top plate 1. An installation cavity 3 is formed at the top of the top plate 1, and a top cover 4 is installed inside the installation cavity 3. A water inlet pipe 5 is connected to the top of the top cover 4. A first water pump 6 is fixedly sleeved on the outer wall of the water inlet pipe 5. Vertical plates 7 are symmetrically installed between the top plate 1 and the base 2. Two sets of transparent plates 8 are symmetrically installed between the two sets of vertical plates 7. The transparent plates 8 have an arc-shaped structure. One set of vertical plates 7 has a discharge port 9. An installation box 10 is installed at one end of the vertical plate 7. A collection cavity 11 is formed at the bottom of the installation box 10. The collection cavity 11 and the discharge port 9 are connected... The collection chamber 11 is connected to the collection box 12, which has an open top and a slot 13 at the bottom edge. A first filter screen 14 is installed in the slot 13. A handle 15 is installed at the bottom center of the collection box 12. An installation plate 16 is installed at the bottom edge of the collection box 12. The top end of the installation plate 16 away from the collection box 12 slides against the bottom edge of the installation box 10. A screw 17 is installed below the installation plate 16. The output end of the screw 17 passes through the installation plate 16 and is threaded to the bottom of the installation box 10.

[0026] For example, such as Figure 1 , Figure 2 and Figure 3 As shown, another set of the upright plates 7 has a water outlet 18 at its bottom, and a screen is installed inside the water outlet 18. Two sets of water storage boxes 19 are symmetrically installed on one side wall of the upright plate 7. Several sets of nozzles 20 are installed at equal intervals on the top of each set of water storage boxes 19. A transport pipe 21 is provided between the top plate 1 and the base 2. Two sets of second water pumps 22 are fixedly sleeved on the transport pipe 21. The transport pipe 21 is connected to the two sets of water storage boxes 19. The two sets of second water pumps 22 are respectively installed on the two sets of water storage boxes 19. A storage container is provided at the center of the top of the base 2. The groove 23 has a motor 24 installed at the center of the bottom inner wall of the base 2. The groove 23 has a partition 25. The output end of the motor 24 passes through the partition 25 and is connected to a mounting column 26. Two sets of mounting frames 27 are symmetrically installed between the two sets of upright plates 7. Two sets of mounting rings 30 are movably sleeved on the mounting column 26. A second filter screen 28 is connected between each set of mounting frames 27 and mounting rings 30. Two sets of scrapers 29 are symmetrically arranged on the top of each set of second filter screens 28. Each set of scrapers 29 is installed on the mounting column 26.

[0027] Working principle: The first water pump 6 starts, transporting water into the equipment through the inlet pipe 5. After being filtered by two sets of second filter screens 28, the water falls onto the top of the partition plate 25 and is then output to the outside of the equipment through the outlet 18. The dual-layer filtration mechanism (first filter screen 14 and second filter screen 28) can more thoroughly remove impurities from the water, ensuring water quality cleanliness. Simultaneously, the transparent plate 8 design allows for direct observation of the filtration process, increasing the transparency and reliability of the equipment. The second water pump 22 starts, transporting water through the transport pipe 21... The water is transported to the water storage box 19 and sprayed by the nozzle 20 to backwash it. The motor 24 drives the mounting column 26 to rotate and moves the scraper 29. The scraper 29 scrapes off the impurities filtered down from the top of the second filter screen 28 and pushes them through the discharge port 9 and the collection chamber 11 before they fall into the collection box 12 for collection. Turn the screw 17 to pull out the mounting box 10 and the mounting plate 16. Pull the handle 15 downward to move the collection box 12 out of the collection chamber 11. The impurities collected in the collection box 12 can be processed. The reverse operation can be used for installation.

[0028] The motor 24 drives the mounting column 26 to rotate, which in turn drives the scraper 29 to move along the surface of the second filter screen 28. This effectively removes impurities from the filter screen, achieving an automatic cleaning effect, reducing the workload of manual maintenance, and maintaining the high-efficiency operation of the equipment.

[0029] Rotate screw 17 to remove mounting box 10 and mounting plate 16, pull handle 15 downward to move collection box 12 out of collection chamber 11, which can process the impurities collected in collection box 12. Reverse operation to install, which improves convenience.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
