Working principle:

first, sewage is discharged to the surface of the mesh plate 2 through the drain pipe 4, liquid sewage flows to the back through the mesh 201 of the mesh plate 2, and solid dirt in the sewage slides down along the surface of the mesh plate 2 and enters the interior of the screw conveyor 301. The third motor 302 is started, the solid dirt is transported by the screw conveyor 301, and in the transporting process, the solid dirt is extruded by the thrust of the screw blade of the screw conveyor 301.

The second motor 602 is started to drive the sewage discharge pipe 4 to move left and right, so that sewage is uniformly discharged on the surface of the sieve plate 2, the utilization rate of the sieve plate 2 is increased, and the efficiency of separating sewage from solid dirt is improved.
