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, resolving technical challenges such as clogging in previous generations of dewatering equipment, inability to process low-concentration and oily sludge, high energy consumption, and complex operation. It achieves an efficient and energy-saving dewatering goal. The dewatering machine can achieve efficient flocculation under fully automatic operation, continuously complete sludge concentration and squeezing dewatering, and ultimately 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 conditioning tank, sludge thickening and dewatering unit, and collecting tank. The main body consists of fixed rings and movable rings stacked together, with a spiral shaft running through them, forming a filtering device. The front section is the thickening section, and the rear section is the dewatering section. The gap between the fixed and movable 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's obstruction, continuously reducing the volume to achieve complete dewatering.
