Machine screw volute sludge dewatering press for sludge dewatering treatment
Product Overview
Description
Multi Disc Dehydrator QY-SPD series Multi-Disc Screw Press is designed to handle various types of sludge in different capacities. The processing capacity is available from 1.5 m3/h to 180m3/h at 0.2% sludge concentration and 0.3m3/h to 28m3/h at 2% sludge concentration.Due to its modular design and compact construction, the capacities can be easily scaled up by running system in parallel to meet almost any capacity as required. Single-screw, double-screw, triple-screw and quadruple-screw makes 1-screw series, 2-screw series, 3-screw series and 4-screw series separately.
Our experienced and trained team of engineers will help you with the installation, operation and maintenance training.
Working Principle
The main unit of the multi-disc screw press dehydrator contains a multi-disc mechanism where ring-shaped “fixed discs” and “movable discs” are alternately arranged at a regular clearance around a “screw shaft”. The main unit consists of a “support frame” that supports the multi-disc structure and a “dam Plate” at the end of the screw shaft. The filtered sludge cakes will be pushed forward by the shaft and finally discharged from the end.
Strcuture and Advantages
Technical Parameters
Working Process

Application The series of finely machined fixed and moving rings placed alternately provides efficient filtration that remains clog free due to the continuous movement of the rings. This eliminates the needs for consumables like filter cloth etc. As clogging is avoided, the Multi-Disc Screw Press is able to handle oil sludge easily. The Multi-Disc Screw Pressis widely used for sludge dewatering and a solid-liquid separation of municipal and industrial wastewater from variety of industries including petroleum, food and beverage, feeds, pharmacy, paper making and painting industry.
