The excess sewage liquid can be discharged through the leakage groove 111 of the solid conveying pipe 113, which can avoid the accumulation of solids in the sewage inside the filter separation box 102 and cause blockage, and effectively improve the separation of liquid and solid in the sewage.

[0025] like Figure 1 and Figure 3-4 , Figure 5 As shown, one end of the spiral blade shaft 117 is connected to the inside of the first waterproof gasket 118 and the second waterproof gasket 121 by passing through, and one end of the first waterproof gasket 118 is connected to one end of the solid conveying pipe 113 by bolts.
