The scraping portion includes a first scraper 10 and a second scraper 11;

[0036] The collecting assembly is arranged in an annular shape on the outer wall of the filter body 1, and includes a collecting box 5 and a filter plate 13.

[0037] like Figure 2 and Figure 3 As shown, the servo motor 3 is fixedly connected to the top axial position of the filter body 1 through the motor frame, the top of the rotating shaft 8 is set at the output end of the servo motor 3, and the bottom end of the rotating shaft 8 is rotatably connected to the top position of the filter assembly 7. The stirring blades 9 are arranged in a circle and fixedly connected to the two ends of the outer wall of the rotating shaft 8. The first scraper 10 is fixedly connected to the stirring blade 9 on the same side close to one end of the inner wall of the filter body 1. The second scraper 11 is fixedly connected to the bottom end of the outer wall of the rotating shaft 8 and fits with the top of the filter assembly 7.

[0038] The collecting box 5 is annular and fixedly connected to the outer wall of the filter body 1 at the top and bottom of the filter assembly 7. The inner wall of the filter body 1 is located at the top of the filter assembly 7 and is provided with a plurality of circumferentially arranged penetrating impurity removal ports 12, which extend to the inner wall of the collecting box 5. The inner wall of the bottom of the collecting box 5 is provided with a plurality of circumferentially arranged return ports 15, which extend to the inner wall of the filter body 1, and the bottom of the cross-section of the return port 15 is inclined.

[0039] The filter plate 13 is fixedly connected to the middle position of the inner wall of the collection box 5 . The filter plate 13 is annular and fits the inner wall of the collection box 5 . The filter plate 13 is provided with a plurality of filter holes 14 arranged in a circumferential pattern.

[0040] like Figure 4 As shown, first scraping grooves 16 are provided at both ends of the outer wall of the first scraper 10. The first scraping grooves 16 are connected to the inner walls on both sides of the first scraper 10. The first scraping groove 16 is concave at one end close to the inner wall of the filter body 1, and is convex at one end away from the inner wall of the filter body 1.

[0041] By setting up the first scraping groove 16, the concave design of the first scraping groove 16 can reduce the contact area with the inner wall of the filter body 1, increase the pressure, and improve the scraping effect. The convex design guides the scraped impurities to fall, avoiding the impurities being retained in the first scraping groove 16 and affecting the cleaning effect on the inner wall of the filter body 1.

[0042] like Figure 4 As shown, a plurality of linearly arranged rotation holes are provided on the outer wall of the first scraper 10 close to the filter body 1 , and balls 17 are rotatably connected to the inner walls of the rotation holes.

[0043] The ball 17 is provided and designed to reduce friction with the inner wall of the filter body 1 , thereby preventing excessive friction between the two from causing jamming and affecting the cleaning effect of the inner wall of the filter body 1 .

[0047] The working principle of the utility model is as follows: when filtering is needed, water is injected into the filter body 1 through the feed inlet 2, and impurities in the water are filtered out through the filter assembly 7 and fall into the bottom position of the filter body 1. The water can be injected into the filter body 1 again through the water pump in the reflux pipe 4 for filtration. At this time, the servo motor 3 is turned on, and the servo motor 3 can drive the stirring blade 9 to rotate through the rotating shaft 8 to stir the raw materials and improve the filtration efficiency of the raw materials. When the rotating shaft 8 rotates, the impurities on the inner wall of the filter body 1 and the top of the filter assembly 7 can be scraped off by the first scraper 10 and the second scraper 11. When the second scraper 11 rotates, the scraped impurities can be moved along the arc surface of the second scraper 11 to the end away from the rotating shaft 8, and enter the collection box 5 through the impurity removal port 12, and the impurities are filtered out through the filter holes 14 on the filter plate 13 and stored at the top of the filter plate 13. The aqueous solution entering the collection box 5 can fall into the bottom of the filter body 1 through the return port 15, and reflux through the reflux pipe 4 for filtration again.
