Technical Field

[0001] The utility model relates to the technical field of sludge dewatering, in particular to a screw stack type sludge dewatering device. Background Art

[0002] Sludge is an inevitable product of sewage treatment and contains a high amount of water. In order to reduce the pollution of sludge to the environment, sludge is often dehydrated before being discarded.

[0003] The screw stack sludge dewatering machine is a water treatment equipment widely used in municipal sewage treatment projects as well as petrochemical, light industry, chemical fiber, papermaking, pharmaceutical, leather and other industrial sectors. The common working process of the screw stack sludge dewatering machine is as follows: sewage and chemicals are introduced into the flocculation tank, and the sewage is stirred by the stirring blades driven by the stirring motor. Then the sewage enters the main body of the screw stack, and the main shaft motor drives the screw shaft to rotate. Under the action of the screw shaft, the sludge is transported to the concentration section and the dewatering section, and the water separated from the sludge flows into the water collection tank.

[0004] However, since the sludge contains large hard impurities, the conventional screw-type sludge dewatering machine does not have a filtering effect, which makes the screw shaft easily damaged.

[0005] Therefore, it is necessary to provide a screw stacking sludge dewatering device to solve the above technical problems. Utility Model Content

[0015] Beneficial effects:
