Product Description

Screw Press Sludge Dewatering Machine is suitable for sludge dewatering of large, medium and small sewage plants. The dewatering machine replaces the traditional filter cloth and plate frame sludge dewatering method, reduces the investment cost and improves the treatment efficiency. It is suitable for municipal sewage treatment project and sludge dewatering treatment in food processing, printing and dyeing, paper making, pharmaceutical, leather and other industries, especially for slaughtering, petrochemical oily sludge dewatering treatment.

Working Principle

Composition: The equipment is mainly composed of frame, screw shaft, moving ring, static ring, separation ring, filtrate collecting tank, flocculating mixer, drive reducer, electrical control box and so on.

Basic Working Process:

  1. Sludge is transported to the flocculation reaction tank via sludge pump.
  2. Sludge and flocculant (PAM) are fully mixed into large flocs.
  3. The solid-liquid mixture enters the spiral cavity through pipe gravity flow.
  4. The spiral axis rotation moves sludge from concentration to dehydration parts.
  5. Filtrate flows from gaps between rings; mud cake is discharged through the back pressure plate.
Main Features & Advantages
  • Oily Sludge Treatment: Effectively handles oily sludge compared to traditional belt and plate frame dehydrators.
  • Anti-Clogging: Unique dynamic and static ring filter joint structure with self-cleaning function.
  • Compact Design: Space-saving, convenient installation, and small footprint.
  • Durable Construction: Made almost entirely of stainless steel for a long service life.
  • Automatic Operation: Simple operation and maintenance through various induction devices.
