Product Details

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, resolving technical challenges like clogging in previous-generation dewatering equipment, inability to handle low-concentration sludge and oil-containing sludge, high energy consumption, and complex operation. It achieves the goal of efficient and energy-saving dewatering. The machine can achieve efficient flocculation under fully automatic operation, continuously complete sludge concentration and squeezing dewatering tasks, and recycle or discharge the collected filtrate. 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, coagulation and conditioning tank, sludge thickening and dewatering unit, and collecting tank into one unit. 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 to the dewatering section. The spiral shaft continuously drives the rings to sweep the gap, preventing clogging. As the spiral shaft rotates, it pushes the sludge from the thickening section to the dewatering section, generating a significant internal pressure due to the back pressure plate, constantly reducing the volume to achieve thorough dewatering.
