Sludge dewatering screw press

for wastewater treatment

Volute sludge dewatering machine can be widely used in municipal sewage treatment engineering and water treatment systems in petrochemical, light industry, chemical fiber, paper, pharmaceutical, leather and other industrial industries. The actual operation shows that the volute sludge dewatering machine can create considerable economic and social benefits for customers. Working principle: 1. Concentration: When the screw pushes the shaft to rotate, the multiple solid laminated plates set on the periphery of the thrust shaft move relative to each other. Under the action of gravity, water is filtered out from the gaps of the relatively movable laminated plates to achieve rapid concentration. 2. Dehydration: The concentrated sludge moves forward with the rotation of the screw shaft; along the mud cake outlet direction, the pitch of the screw shaft gradually becomes smaller, the gap between the ring and the ring also gradually becomes smaller, the volume of the spiral cavity Continuously shrinking; Under the action of the back pressure plate at the outlet, the internal pressure gradually increases. Under the continuous driving of the screw pushing shaft, the water in the sludge is squeezed and discharged, the solid content of the filter cake is continuously increased, and finally the sludge is realized. Continuous dehydration. 3. Self-cleaning: The rotation of the screw shaft promotes the continuous rotation of the swimming ring. The equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, thereby cleverly avoiding the common plugging problem of the traditional dewatering machine.
