Fold the screw type sludge dewatering machine can be widely used in municipal wastewater treatment engineering and petrochemical light chemical fiber papermaking pharmaceutical leather industry of water treatment systems, such as the actual operation proves that the stack of screw type sludge dewatering machine for customers to create considerable economic benefits and social benefits.
Working Principle:
1. concentrate when screw drive shaft rotation, is located in the drive shaft periphery of multiple solid laminated relative movement, under the effect of gravity, the water from the relative motion of laminated clearance leach, achieve rapid enrichment.
2. dehydration: after enrichment of sludge as the rotation of the screw axis moves forward continuously;Along the outlet direction of the mud cake, the screw pitch of the spiral shaft gradually becomes smaller, and the gap between the ring and the ring decreases gradually, and the volume of the spiral cavity shrinks constantly.Back at the exit pressure plate, under the action of internal pressure increased, the screw drive shaft, in turn, continuous operation, driven by the water squeezed out of the sludge, filter cake higher solid content, the realization of ultimate sludge dehydration.
3. consecutive self-cleaning: the rotation of the screw axis, constantly promote swimming ring rotation, swimming equipment rely on the retaining ring and ring to move between consecutive since the cleaning process, thus avoided ably to traditional dewaterer widespread congestion.
