The snail sludge dewatering machine belongs to the screw press dewatering machine to a certain extent. In the process of operation, the sedimentation tank and the sludge concentrating tank can be reduced, so that the construction cost of the sewage station can be saved, and the snail sludge dewatering machine is in operation. Ingenious use of multi-ring automatic cleaning and filtering technology instead of traditional filter filtration, self-cleaning filtration technology to ensure continuous and stable mud-water separation of the dehydrator, strong extrusion force generated by screw diameter and pitch change, and swimming ring and fixed A small gap between the rings to achieve sludge extrusion and dewatering is a new type of solid-liquid separation equipment.
The main body of the snail sludge dewatering machine is stacked on each other by a fixing ring and a swimming ring, and the spiral shaft penetrates the filtering device formed therein during operation. The front part is a concentrating part and the rear part is a dewatering part. The filter slit formed between the fixed ring and the swimming ring and the pitch of the screw shaft gradually become smaller from the concentrating portion to the dewatering portion.
The rotation of the screw shaft of the snail sludge dewatering machine drives the sludge from the concentrating part to the dewatering part, and also drives the swimming ring to clean the filter joint to prevent clogging. After the sludge is concentrated by gravity in the enrichment section, it is transported to the dehydration section. During the advancement process, as the filter joint and the pitch gradually become smaller, and the back pressure plate blocks, a large internal pressure is generated, and the volume is continuously reduced. To achieve the purpose of full dehydration.
