[0036] From the above description, it can be seen that: when the cleaning mechanism 4 cleans the filter plate 26, the motor III 41 starts, drives the screw II 42 to rotate, and causes the wire brush 45 to slide along the sliding shaft 43 to clean the filter plate 26, and pushes the fiber material on the filter plate 26 into the sewage discharge bin 103, and finally the fiber material is discharged from the sewage discharge port at the bottom of the sewage discharge bin 103.
