The screw type sludge dewatering machine is a new solid-liquid separation equipment which uses the screw extrusion principle, through the strong extrusion pressure produced by the change of screw diameter and pitch, and the tiny gap between the moving ring and the fixed ring.
Construction principle:
The main body of the screw type sludge dewatering machine is composed of multiple fixed rings and swimming rings, and the screw shaft runs through the filter device. The former section is the concentration part and the latter is the dehydration part. The sludge concentration and pressing dehydration work is completed in a cylinder. The traditional filter cloth and centrifugal filtration mode are replaced by the unique and delicate filter body mode.
Dehydration principle:
Sludge is transported to the dehydration part after gravity concentration in the concentration part. During the process of advance, with the decrease of filter gap and pitch, and the blocking effect of back pressure plate, the sludge will generate great internal pressure and the volume will be reduced continuously to achieve the purpose of full dehydration.
