Automatic sludge dewatering screw filter press machine for industry wastewater

Fold screw type sludge dewatering machine belongs to screw press dewaterer, can reduce the sedimentation tank and sludge concentration tank, saving the cost of sewage plant construction. Fold screw type sludge dewatering machine is provided with multiple ring plate automatic cleaning filter technology replaces the traditional filter sieve, self cleaning filter technology to ensure continuous stability of mud dehydrator separation effect, through the screw diameter and pitch changes produce strong extrusion, and the tiny cracks between swimming ring with fixed ring, implementation to squeeze dewatering of sludge, is a new type of solid-liquid separation.

Structure principal:

1. The body of the dewatering machine is composed of a fixed ring and swim ring overlapping, screw axis running through the formation of the filtering device. The front is enrichment, posterior segment is dehydration
2. The filtering space between fixed ring and moving ring  and pitch of screw axis from concentration to the dehydration of gradually become smaller.

The rotation of the screw axis in promoting to the dehydration of sludge from the enrichment of conveying the same time, constantly bring swimming ring cleaning filter seam, to prevent clogging.

4. Sludge in the enrichment department after gravity concentration, by the ministry of transport to dehydration, in the process of forward with seam filter and pitch became smaller, as well as the back plate under the action of blocking, produce great internal pressure, volume shrinking, achieve the goal of fully dehydration.
