Stacked screw dewatering machine Stacked screw sludge dewatering machine

Stacked screw dewatering machine Stacked screw sludge dewatering machineMainly used for sludge concentration and dewatering in sewage treatment plants, it has the characteristics of small footprint, light weight, and simple automatic operation and maintenance. For general municipal sewage treatment plants, the moisture content of the treated sludge is generally 80%.

working principle

When the equipment is running, the sludge enters the filter cartridge from the feed port and is pushed towards the discharge port by the spiral blades. As the pitch of the spiral shaft blades gradually decreases, the sludge is subjected toThe pressure also increases continuously and begins to dehydrate under the action of pressure. Water flows out from the gap between the fixed ring and the moving ring. At the same time, the equipment relies on the self-cleaning function between the fixed ring and the moving ring to clean the filtering gap and prevent blockage. After dehydration, the mud cake is discharged from the discharge port under the pushing action of the screw shaft.

main structure

The spiral dewatering machine is mainly composed of fixed rings, moving rings, spiral shafts, driving devices, collection tanks, and sludge outlets. Among them, the fixed ring and the moving ring are arranged at intervals, forming multiple filtering chambers. The spiral shaft runs through it, driving the moving ring to make circular motion to prevent blockage.

Features and Advantages

Efficient dehydrationThe stacked screw dewatering machine can dewater sludge with a moisture content of up to 99% to a moisture content of less than 80%, greatly reducing the volume of sludge and facilitating subsequent treatment and disposal.

Energy-saving and environmental protectionThe device has low energy consumption and low noise during operation, and adopts a multi overlapping spiral filter pressing method with self-cleaning filter seams, which is non clogging, water-saving and energy-saving.

stable operationThe device has a simple structure, small footprint, high degree of automation, and stable and reliable operation.

widely usedSuitable for various sludge treatment scenarios, including municipal sewage treatment, industrial wastewater treatment, food processing, aquaculture, and other fields.
