[0026] Furthermore, the mud removal mechanism also includes a lower rod 401 , which is fixedly connected to the cleaning box 4 . A lower spray head 402 is provided on the lower rod 401 , and the lower spray head 402 is located directly below the screen belt 53 .

[0027] Furthermore, an upper mud removal assembly is plugged into the outlet right plate 103. The upper mud removal assembly includes a plug-in sleeve, which is fixedly connected to a support plate 406, and a mud shoveling plate 408 is provided at one end of the support plate close to the inlet left plate, and plugging plates are provided on both sides of the support plate. The plug-in sleeve, the support plate, and the two plugging plates form a mud storage bin, and a plurality of upper spray heads 407 are provided below the support plate, and the upper spray heads 407 are located directly above the screen belt 53.

[0028] The scheme is detailed. The plug-in sleeve includes a plug-in left plate 403, a plug-in top plate 404 and a plug-in right plate 405. The two ends of the plug-in top plate 404 are respectively connected to the plug-in left plate 403 and the plug-in right plate 405.

[0033] In working mode, sewage can enter the water inlet box 2 along the water guide sleeve. Since a screen belt is provided at the bottom of the water guide sleeve, and a plurality of filter holes are provided on the screen belt, the sewage falls into the bottom of the water inlet box after being filtered by two layers of screen belts, and a layer of silt or other debris is attached to the surface of the screen belt at this time, and the driving motor is activated to move the screen belt with silt attached for a distance, so that the screen belt facing the bottom of the water guide sleeve can perform filtering work again. Since the water inlet box, the connecting component and the water outlet box form a communicating vessel, the sewage flows into the water outlet box after being filtered by the filter cotton 33 in the connecting pipe. Since the water outlet 105 is above the screen belt, when the water outlet is connected to a water pump, the sewage in the water outlet box is filtered by the secondary screen belt again and flows out from the water outlet.

[0034] At the same time, the screen belt with silt attached to it is gradually moved from the water inlet tank to the cleaning tank under the drive motor. Because of the mud shoveling plate 408, the mud shoveling plate 408 can shovel the silt on the surface of the screen belt into the mud storage bin, and the remaining silt on the surface of the screen belt is sprayed into the lower cone tube under the spray of the upper spray head. After cleaning, the screen belt continues to move to the water outlet tank to complete the subsequent water filtering work. When the screen belt in the water outlet tank is driven by the drive motor to move into the cleaning tank, a lower spray head is provided under the screen belt, which can be used for spraying and desilting the screen belt.

[0035] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
