Product Details

The screw press sludge dewatering machine adheres to principles such as force and water in the same direction, thin-layer dewatering, appropriate pressure application, and extended dewatering path, solving technical challenges like clogging, inability to process low-concentration and oil-containing sludge, high energy consumption, and complex operation faced by previous generations of dewatering equipment. It achieves the goal of efficient and energy-saving dewatering. The dewatering machine can perform efficient flocculation under fully automatic operation and continuously complete sludge concentration and squeezing dewatering, with the collected filtrate recycled or discharged. It is widely used in municipal wastewater treatment projects and water treatment systems in industries such as food, starch, oil, pharmaceuticals, chemicals, papermaking, and leather.

Structural Principles

The Screw Press Sludge Dewatering Machine integrates an automatic control cabinet, flocculation conditioning tank, sludge thickening and dewatering unit, and liquid collection tank into one. The main body consists of stacked fixed rings and sliding rings, with a spiral shaft running through them to form a filtration device. The front section is the thickening section, and the rear section is the dewatering section. The gap between the fixed and sliding rings, as well as the pitch of the spiral shaft, gradually decreases from the thickening section to the dewatering section. The spiral shaft continuously drives the rings to sweep the filter gap, preventing clogging. As the spiral shaft rotates, it pushes the sludge from the thickening section to the dewatering section, generating a high internal pressure due to the back pressure plate, continuously reducing the volume to achieve complete dewatering.
