Mud and sand precipitation treatment recycling device

The utility model provides a mud and sand sedimentation treatment recycling device which comprises a sedimentation tank and further comprises a mud and sand tank arranged at a slurry outlet in the lower side of the sedimentation tank, a mud discharge pipe is connected to the other end, opposite to the sedimentation tank, of the mud and sand tank, and the other end, away from the mud and sand tank,of the mud discharge pipe is communicated with a sewage inlet of a sewage pump installed on a fixing base. The driving motor is powered on to drive the connecting shaft to rotate, so that the spiralplate mounted on the connecting shaft rotates along with the connecting shaft, the rotating spiral plate drives the mud to move forwards, and the mud and the water in the mud are separated through centrifugal force generated in the rotating process of the rotating spiral plate, so that the mud and the water in the mud are separated. And separated water flows into the water collecting pool throughthe water outlet holes to b
