The stack screw sludge dehydrator is a specialized equipment used for sludge dewatering. It operates on the principle of the double screw type enrichment dehydrator. The sludge enters the screw press through the sandwich screw propeller and travels along the spiral axis of the screen tube, where it is enriched and dehydrated. As the press rotates continuously, the sludge is separated from water for effective dehydration. The benefits of the superposed spiral sludge dehydrator are its easy maintenance and operation, compact size, cheap running costs, and excellent dewatering efficiency. In addition, the spiral sludge dehydrator operates without the need for chemical additions and poses no risk of secondary pollution, according to the fundamentals of sustainable development and successfully resolving issues with the sewage treatment process. The screw type sludge dehydrator is a crucial component of the sewage treatment plant because it can quickly remove water from the sludge, thicken the sludge, reduce volume, and lower the water content of the solid sludge, making it easier to process and transport while also lowering environmental pollution.

Features of sludge dewatering machine

Metering tank: The conveying pump moves the sludge to the metering tank, and the return pipe returns the excess material to the sludge storage tank.
Flocculation mixing tank: To create a nice alu m flower, the measured sludge is thoroughly mixed and agitated in the flocculation mixing tank along with the injected polymer flocculant.
Dehydration body: The majority of the filtrate is discharged at the dehydrated part, where it is completely dehydrated as a result of a constant increase in pressure in the internal cavity. The sludge enters the dehydration body through the mud inlet, where gravity concentration happens instantaneously in the concentration part of the front section. There is no dewatering portion in the sludge thickener's dewatering body.
Sludge outlet: The sludge is more fully dehydrated and is released from the sludge outlet in the form of mud cake. The back pressure plate placed at the sludge outlet creates a blocking force in the opposite direction. The sludge outlet is concentrated so that the pressure in the body cavity is further increased. The concentrated sludge was released through the sludge outlet by the sludge thickener. The sludge thickener's side with the sludge outflow does not have a back pressure plate.

Detials of of sludge dewatering machine

Benefits of Performance of sludge dewatering machine

Sludge enters the filter cartridge through the feed port when the device is operating, and the spiral shaft revolving disc pushes it toward the discharge port.
The pressure on the sludge rises as the pitch between the spiral shaft spinning disc gradually decreases.
The water starts to dry due to the pressure difference, and it exits the filter gap between the active ring disc and the fixed ring disc.
The mud cake is released from the discharge port under the assistance of the spiral shaft after adequate dehydration, and the apparatus depends on the self-cleaning mechanism between the fixed plate and the moving plate to clear the filter gap and prevent clogging.
The company has created a focused machine that is more economically priced to operate and has a more practical construction based on the various qualities of sludge.
