spiral type screw press sludge dewatering machine food factory sludge solid liquid separation sewage treatment equipment
The stacked screw type sludge dehydrator skillfully uses the multiple ring piece automatic cleaning and filtering technology to replace the traditional filter screen filtering. The self cleaning and filtering technology ensures the continuous and stable sludge water separation effect of the dehydrator. The squeeze dewatering of sludge is realized through the strong squeeze pressure generated by the change of screw diameter and screw pitch, and the small gap between the movable ring and the fixed ring. It is a new type of solid-liquid separation equipment.
Main Features
1. The screw stacking dehydrator has the characteristics of small floor area, less flushing water, low noise, good workshop environment, etc.
2. It is used for the direct dehydration of activated sludge in small sewage stations, and the design of sludge thickener can be canceled in the construction of sewage stations to save costs.
3. At the same sludge treatment capacity, compared with the centrifugal dehydrator, the spiral type dehydrator can save 85% energy and occupy only half of its floor space; In terms of surface cleaning, it can save 95% water compared with the belt dehydrator.
