[0038] The working principle of the above-mentioned embodiment is that sewage enters the sedimentation tank 3 and the suspended solids, particulate matter and the like in the sewage gradually deposit at the bottom of the sedimentation tank 3 to form a sludge layer, and clean upper water is left above the sedimentation tank 3.

Finally, the motor 14 drives the conveying shaft 6 to rotate, thereby driving the auger blade 7 to rotate between the sedimentation tank 3 and the extension pipe 4. The helical structure of the auger blade 7 pushes the sludge at the bottom to the right end and opens the electric valve, and finally the sludge is discharged to the external sewage pump through the sludge discharge pipe 5, thereby realizing the automatic cleaning of the sludge.
