Screw Press

The Sludge Dewatering Screw Press utilizes the dewatering principles of force-water homo-direction, thin-layer dewatering, proper pressure and extension of the sludge dewatering path. The new equipment, more advanced than the traditional dewatering equipment which are easily blocked, unsuitable for low-concentrated sludge and oily sludge, of high consumption and difficult to operate, well eliminate these problems and are of higher efficiency and power saving.

Sludge dewatering press is equipped with unique Technology, which allows dewatering sludge while automatic self-cleaning the filter mesh. This enables stable and constant dewatering without clogging. The filtering device formed by fixed rings, moving rings, and a spiral in the middle. With screw extrusion principle, strong extrusion pressure generated when the screw diameter and pitch change, tiny gap between the moving ring and the fixing ring to achieve sludge extrusion dehydration.

Sludge goes from the feed inlet into the metering tank, moved to the flocculation mixing tank, then moved to the dewatering tank, by the push of the spiral shaft rotary vane, the pitch is gradually reduced, the pressure is increased, the pressure difference makes sludge to be dehydrated, water outflow from fixed rings and moving rings. The device has self- cleaning function between the fixed rings and the moving rings, and the clearance between the filter and the filter is prevented from being blocked. After sludge is full dehydration, sludge cake is discharged from the discharge port under the action of the propeller shaft.

With self-cleaning function, clogging is avoided. It can handle oily sludge without any trouble while separating the water from the sludge easily. Also, don’t need large quantity of flushing water, reduce water consumption.

Small Type Design :

It includes electric cabinet, dosing tank, flocculation mixing tank etc. The compact appearance takes small space, easy on repairing, replace and moving.

Operation Easy :

It can operate automatically for 24 hours, unmanned, Daily maintenance is easy and saving time.
