2025Best-Selling Screw Press Sludge Dewatering Machine for Poultry Wastewater Treatment
Product Overview
The volute-type sludge dewatering machine consists of two main
sections: the concentration zone and the dewatering zone. Both
sections are formed by fixed rings and moving rings. The moving
rings are equipped with an independent automatic cleaning system.
During operation, the moving shaft drives the rings to continuously
clean the filter gaps, effectively preventing solid clogging and
ensuring stable, continuous performance with minimal clean water
consumption.
Working Principle
The machine is supported by a four-point walking beam spanning the
sedimentation tank. It operates on rails installed along both sides
of the tank. As the equipment travels from one end to the other, it
simultaneously extracts sludge. Upon reaching the end of the tank,
it reverses direction and continues the suction process, completing
a full working cycle automatically.
Main Components
The system includes:
Main working bridge
Sludge suction and discharge pipes
Submerged suction pump
Bilateral drive mechanism
Electrical control cabinet
Track and sliding cable system
Key Advantages
Compact Design
Integrates electrical controls, metering, flocculation mixing, and dewatering in one unit.
Small footprint, easy operation, maintenance, and part replacement.
Anti-Clogging Performance
Self-cleaning mechanism avoids manual filter cleaning.
Reduces water usage and internal circulatory load.
Ideal for oily and challenging sludge types.
Low-Speed Operation
Screw rotation at only 2–3 RPM ensures low energy consumption.
Minimal noise, vibration, and mechanical failure for safe, reliable performance.
User-Friendly Operation
Full automation through the control cabinet.
Synchronized with aeration units, sludge pumps, and dosing systems for 24/7 operation.
Easy and infrequent maintenance.
Durable Construction
Manufactured using high-quality stainless steel for extended service life.
Only the screw shaft and traveling ring require occasional replacement.
