10m³/H Integrated Screw Press Sludge Dewatering Machine – Concentration, Frying & Solid-Liquid Separation All-in-One System

This screw-type sludge dewatering machine features a robust structure comprising multiple fixed rings, moving rings, and a spiral filtration unit. It seamlessly integrates filtration, concentration, and pressing dehydration into a single, efficient system, enabling continuous processing within one enclosed cylinder.

In the concentration zone, the relative motion between fixed and moving rings allows rapid discharge of filtrate without clogging. In the dehydration section, the volume of the spiral chamber gradually decreases, significantly increasing internal pressure. Combined with an adjustable back-pressure plate mechanism, this system achieves efficient solid-liquid separation without relying on traditional filter cloths or centrifugal methods. Its innovative self-cleaning technology ensures continuous operation with minimal maintenance, setting a new standard in sludge dewatering.

Working Principle
During operation, sludge is fed into the filtration cylinder and conveyed by rotating spiral blades toward the discharge end. As the pitch of the blades gradually decreases, mechanical pressure on the sludge increases, progressively squeezing out moisture. The released water escapes through gaps between the fixed and moving rings. Simultaneously, the self-cleaning action between these rings prevents clogging and maintains consistent filtration performance. Finally, the dewatered sludge cake is discharged through the outlet.

Main Features

Laminated dehydration body:
The stacked screw body is a cylindrical filter structure formed by stacking the fixed ring and the traveling ring and inserting
the screw shaft therethrough. While conveying sludge, the screw shaft drives the traveling ring to make a circular motion. It hasthe function of automatically cleaning the filter slot and is not easy to block, so that the dehydrator can operate continuously and stably.
Wide treatment area, suitable for sludge dewatering in all walks of life:
Municipal wastewater, papermaking wastewater, chemical wastewater, food and beverage processing wastewater, industrial production wastewater, papermaking wastewater, petroleum processing and mining wastewater, etc.
Various product models, exquisite design, small footprint:
Compared with the traditional belt type, plate frame and centrifugal dewatering machine, the stacked screw sludge dewatering machine adopts the three-dimensional integrated design of dewatering body, flocculation mixing tank and electric control device.
It is portable to install, occupies a small space, and has good compatibility with auxiliary supporting equipment, greatly reducing the design and construction cost in the early stage. At the same time, as for the replacement project, due to the exquisite design of the overlapping screw, there is no need to carry out the civil construction again.
Simple operation and maintenance:
It can realize 24-hour full-automatic unmanned operation through PLC Remote Control and other methods, reducing the employment and maintenance costs of on-site operators. At the same time, because the design is exquisite, the operation is simple, there is no complicated requirement, and it is easy to learn.
Water saving, power saving and low noise
Since the laminated dehydration main body has the function of self-cleaning filter slot, it does not need a large amount of cleaning water for blocking. Compared with the dehydrator with the same processing capacity, the washing water consumption of the stacker is 1% of that of the belt dehydrator The screw shaft for conveying and compressing sludge has a rotation speed of 2-5 revolutions per minute, low power consumption and economic applicability. The power consumption is 5% of that of the centrifuge.At the same time, due to the small rotating speed and intermittent flushing, the equipment operates without noise.
