Product Details

The screw press sludge dewatering machine adheres to principles such as force and water flowing 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 and oily sludge, high energy consumption, and complex operation. It achieves the goal of efficient and energy-saving dewatering. The dewatering machine can perform efficient flocculation under fully automatic operation, continuously completing sludge concentration and squeezing dewatering, and 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 a full-automatic control cabinet, a coagulation conditioning tank, the main dewatering body of sludge concentration, and a collection tank. The main body consists of a fixed ring and a movable ring layered on top of each other, with a spiral shaft running through it to form a filtration device. The front section is the concentration part, and the rear section is the dewatering part. The gap formed between the fixed and movable rings, as well as the pitch of the spiral shaft, gradually decreases from the concentration to the dewatering section. The spiral shaft continuously drives the rings to sweep the filter gap, preventing clogging. As the spiral shaft rotates, it propels the sludge from the concentration to the dewatering section, generating a significant internal pressure due to the back pressure plate's resistance, continuously reducing the volume to achieve thorough dewatering.
