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 handle low-concentration and oil-containing sludge, high energy consumption, and complex operation faced by previous generation dewatering equipment. It achieves an efficient and energy-saving dewatering goal. The dewatering machine can achieve efficient flocculation under fully automatic operation and continuously complete sludge concentration and squeezing dewatering tasks, ultimately recycling or discharging 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, flocculation conditioning tank, sludge thickening and dewatering unit, and a collecting tank. The main body consists of stacked fixed rings and moving rings, with a spiral shaft running through them to form a filtering device. The front section is the thickening section, and the rear section is the dewatering section. The gap between the fixed and moving 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 pushes the sludge from the thickening section to the dewatering section, generating a significant internal pressure due to the back pressure plate, continuously reducing the volume to achieve complete dewatering.
