Engineering muck slurry recycling and dewatering device

The invention relates to the field of slurry reutilization, in particular to an engineering muck slurry reutilization dewatering device which comprises a supporting frame, a separation assembly is arranged at the lower end of the supporting frame, a drainage assembly is arranged on the side wall of the supporting frame, a driving assembly is arranged at the upper end of the supporting frame, an extrusion assembly is arranged at the lower end of the driving assembly, and the separation assembly comprises a rotating shaft. The rotating shaft is rotationally connected to the side wall of the upper end of the supporting frame, the rotating shaft is rotationally connected to the two L-shaped plates, the rotating frame is pushed to be attached to the supporting frame, then the U-shaped shaft is rotated to move to a gap between the supporting frame and the rotating frame, the gap is blocked through a rubber strip, and then the arc plate is rotated to enable a rubber pad to be attached to the outer wall of the rotati
