Dairy Sewage Screw Press Sludge Dewatering Machine for Waste Water Treatment Plant
Screw press sludge dewatering equipment is a new kind of sewage treatment facility developed by . It uses multilaminated filter and spiral rotation to separate moisture from sludge. Benefiting by the special structure of fixed rings and moving rings, it allows continuous automatic operation in 24 hours without blocking.
As equipment starts running, sludge flows into the filter cylinder and moves forward to sludge cake outlet under the thrust from screwshaft. The whole filter cylinder is composed of fixed rings, moving rings and shaft. The first two sections are thickening zone, last two are dewatering zone, The space between screw blades gets more and more narrower, which means the inner pressure gradually gets bigger. Under this pressure, liquid is squeezed out from the sludge and leaks from the small gaps between rings. And the left dry solid is pushed to the sludge cake outlet.
