Product Details

The screw press dewatering machine follows principles such as water and force in the same direction, thin-layer dewatering, appropriate pressure application, and extended dewatering path, overcoming technical challenges such as easy clogging, inability to process low-concentration sludge 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 perform efficient flocculation under fully automatic operation and continuously complete the tasks of sludge thickening and pressing dewatering, 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 and conditioning tank, sludge thickening and dewatering unit, and collecting tank into one unit. The main body consists of fixed rings and floating rings stacked together, 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 filter gap formed 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 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, while the back pressure plate blocks it, creating a high internal pressure. The volume continuously shrinks, achieving the purpose of full dewatering.
