[0001] The utility model relates to the technical field of sludge treatment, in particular to a new type of sludge dehydration device. Background Art

[0002] After concentration and digestion, the sludge still has a water content of about 95% to 97%, and its volume is still large. Sludge dehydration can further remove the interstitial water and capillary water in the sludge and reduce its volume. After dehydration, the sludge water content can be reduced to 50% to 65%, and its volume is 1 / 10 to 1 / 4 of the original volume, which is conducive to subsequent transportation and treatment.

[0003] Chinese patent CN217377681U discloses a sludge dewatering device. The utility model provides a sludge dewatering device, including a cylindrical treatment box and a recovery box.

A telescopic cylinder is arranged on the side of the cylindrical treatment box, and the piston rod of the telescopic cylinder is connected to the filter plate. The lower part of the cylindrical treatment box is connected to the recovery box through a pipeline, and the recovery box is provided with a drain port. A grid plate is fixedly arranged on the upper part of the cylindrical treatment box corresponding to the filter plate, and the cylindrical treatment box is provided with a stacking screw body on the upper part of the grid plate, and the stacking screw body is composed of a motor and a screw shaft.
