The Screw Press 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 in previous-generation dewatering equipment, inability to process low-concentration sludge and oil-containing sludge, high energy consumption, and complex operation. It achieves the goal of efficient and energy-saving dewatering. The dewatering machine can achieve efficient flocculation under fully automatic operation and continuously complete sludge concentration and squeezing dewatering, ultimately recycling or discharging the collected filtrate. It is widely used in municipal wastewater treatment projects, as well as in water treatment systems for industries such as food, starch, oils, pharmaceuticals, chemicals, papermaking, and leather.

Structural Principle

The Screw Press Sludge Dewatering Machine integrates an automatic control cabinet, coagulation conditioning tank, sludge thickening and dewatering unit, and liquid collection tank. The main body consists of stacked fixed rings and floating 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 floating rings, as well as the pitch of the spiral shaft, gradually decreases from the thickening section to the dewatering section. The spiral shaft continuously sweeps the gap with the rings to prevent clogging. As the spiral shaft rotates, it drives the sludge from the thickening section to the dewatering section, generating a significant internal pressure due to the back pressure plate's resistance, continuously reducing the volume to achieve complete dewatering.
