Valves are arranged on the feed pipe 6, the mud discharge pipe 7 and the drainage pipe 4. The extrusion conveying mechanism is mounted on the conical cylinder 5. The extrusion conveying mechanism has the function of extrusion conveying.
[0022] When dewatering the sludge, the valves on the drain pipe 4, the sludge discharge pipe 7 and the feed pipe 6 are opened, and then the sludge is continuously added into the cavity of the conical cylinder 5 through the feed pipe 6, and then the sludge is transported from left to right in the cavity of the conical cylinder 5 by the extrusion conveying mechanism, and the sludge is squeezed while the sludge is squeezed, and the water in the sludge is squeezed out of the sludge, and then the sludge falls into the chamber of the sealing box 3 through the multiple groups of drainage holes at the lower part of the conical cylinder 5, and then the water is discharged through the drain pipe 4 and collected, and at the same time, the squeezed and dehydrated sludge enters the sludge discharge pipe 7 through the right part of the conical cylinder 5 and is discharged and collected; it can automatically discharge the dehydrated sludge, which improves convenience, and other sludge can be dehydrated while discharging the sludge, and the dehydration has high continuity, higher dehydration efficiency and high practicality.
