Screw Press Sludge Dewatering Machine

The screw press sludge dewatering machine is a low-energy-consumption, small-footprint sludge dewatering equipment. It achieves solid-liquid separation of sludge through a combination of screw extrusion and gravity concentration, and is widely used in various types of wastewater treatment scenarios.


Description

Working Principle:

After the sludge undergoes flocculation to form flocs, it is fed into the thickening section by a feed pump, where gravity is used to achieve initial dewatering. Subsequently, the material is pushed to the dewatering section, where the rotating screw shaft propels the sludge forward. At the same time, the gap between the screw shaft and the fixed and moving rings gradually narrows, creating a continuously increasing squeezing force that squeezes out the water from the sludge. The water is discharged through the gaps between the rings and the filter slots, and the dewatered sludge cake is discharged from the outlet.

 

Structural Composition: 

The core components consist of a fixed ring, a moving ring, a spiral shaft, a flocculation mixing tank, a drive unit, and a cleaning system. The fixed and moving rings are stacked alternately to form the filter chamber, through which the spiral shaft passes. The cleaning system uses high-pressure flushing water to prevent filter clogging and ensure continuous equipment operation.

 

Key features: 

Not prone to clogging, requiring no high-pressure cleaning water or large amounts of flushing water; compact structure, occupying only 1/3 the space of traditional dewatering equipment; highly automated, capable of 24-hour unattended operation; low energy consumption, low operating noise, and low maintenance costs.
