Product Overview

Description


Dewatering Sludge Machine Screw Press is a kind of economic and environmental friendly sludge dewatering equipment. It is a new type of sludge extrusion dewatering equipment by using the principle of screw extrusion, through the strong squeezing force generated by the change of screw diameter and screw pitch, and the tiny gap between the floating ring and the fixed ring, to realize solid-liquid separation. Gdewatering screw press is composed of fully automatic control cabinet, flocculation modulation box, sludge thickening and dewatering device, and liquid collecting tank. GN dewatering screw press is with automatiNc control technology, which can realize the flocculation fully automatic operation, and continuously complete the sludge thickening and squeezing, finally return or discharge the collected filtrate liquid.

ADVANTAGES OF SCREW PRESS DEWATERING MACHINE



  1. Suitable for wide range sludge dewatering and can be used for oily sludge treatment.

  2. Operating continuously and automatically, not easy to block.

  3. Low investment and operation cost, no secondary pollution.

  4. Energy saving and environmental friendly, compact design with small footprint.

  5. Sludge can be dewatered under aerobic conditions to avoid phosphorus release from anaerobic sludge dewatering.


FEATURES OF SCREW PRESS DEWATERING MACHINE





  1. The main body of the screw press sludge dewatering machine is a filtration device composed of fixed ring and moving ring, in which the screw axis runs through. The front section is for concentration and the back section for dewatering.

  2. The filtering gap formed between the fixed ring and the moving ring of the dewatering screw press and the pitch of the screw axis gradually decreased from the concentration section to the dewatering section.

  3. The rotation of the screw press shaft not only pushes the sludge from the concentration section to the dewatering section, but also continuously drives the moving ring to clean the filtering gap to prevent clogging.

  4. After gravity concentration in the concentration section, sludge is transported to the dewatering section. In the process of advance, with the gradual decrease of filtering gap and screw pitch, and the blocking effect of back pressure plate, a great internal pressure is generated; leading the volume is constantly reduced, so as to achieve the purpose of full dewatering.

  5. Dewatering screw press is generally applicable to sludge concentration of 2000mg / L-50000mg / L
