The backwash pipe 14 corresponds to a number of nozzles 17 evenly distributed along the length of the pipe body inside the mesh cylinder 4. The liquid sprayed from the nozzles 17 is in the shape of an umbrella, and the spacing between each nozzle 17 is the connection point of the umbrella. The design of the nozzles 17 is conducive to the overall uniformity of the spray.

[0028] The filter screen is covered by several scraper strips 15 evenly distributed on the circumferential surface of the screen cylinder 4. The scraper strips 15 press the middle of the filter screen tightly, and the two sides of the filter screen are sealed by pressure strips or clamps.

[0029] The filter storage tank 1 is divided into a sewage zone and a slag discharge zone by a weir plate 10. The mesh cylinder 4 is located in the sewage zone, and the brush roller 3 is located above the slag discharge zone of the weir plate 10. The upper edge of the weir plate 10 is higher than the center of the mesh cylinder 4, forming a slag discharge port to prevent water overflow.

[0030] The slag-discharging plate 5 is tilted, and the highest point of the slag-discharging plate 5 is located at the intersection of the mesh cylinder 4 and the brush roller 3. The lowest point of the slag-discharging plate 5 extends out of the filter water storage tank 1 and extends above the sludge collection tank 6.

That is, a scraper strip 15 is provided at the circumferential surface of each mesh cylinder reinforcing rib 4.2.

[0036] Understandably, various impurities such as suspended solids, slurry, and lint enter from the inlet 7 of the housing 1. The liquid permeates into the screen cylinder 4, where the impurities are trapped or precipitated by the filter screen. A suitable water pump can be connected through the exposed siphon pipe 8 to extract the liquid from the screen cylinder 4. As the screen cylinder 4 and brush roller 3 operate, the impurities quickly adhere to the surface of the filter screen with the water flow. The sediment is scraped off by the scraper 15, and the brush roller 3 cleans the surface of the screen cylinder. The impurities are then transported to the collection box 6 by the slag discharge plate 5. The backwash pipe 14 can select a water pump to return water or connect to other cleaning liquids from the backwash inlet to clean the screen cylinder 4 from the inside out, achieving a self-cleaning and non-clogging process.
