Sludge dewatering device for ecological management of water conservancy river channel

The utility model relates to the technical field of river sludge dewatering, in particular to a sludge dewatering device for ecological management of a water conservancy river, which is characterized in that a dewatering part is arranged in an outer cylinder, and a feeding part is mounted at one end of the outer cylinder. Sludge input is achieved through the arrangement of the feeding piece, the spiral conveyor is driven by the rotating shaft to rotate, then sludge extrusion and conveying are facilitated, the extruded sludge is output from the other end of the inner barrel, continuous operation of equipment is facilitated, water can flow into the water storage bin conveniently through the arrangement of the water leakage holes, and the water leakage effect is improved. And the inner cylinder is rotated through the transmission part, so that the high-pressure spray head and the brush can continuously wash the inner cylinder, the water leakage holes are prevented from being blocked, and the practicability of th
