ZDL stacking screw type sludge dewatering machine
ZDL screw type sludge dewaterer integrates automatic control cabinet, flocculation and conditioning tank, sludge thickening and dewatering body and collecting tank. It can achieve high efficiency flocculation under the condition of full automatic operation, and continuously complete sludge thickening and pressing dewatering, and eventually return or discharge the collected filtrate. When the equipment is running, the sludge is pushed from the inlet to the filter cartridge and moves to the unloading port by the screw-shaft rotating plate. As the pitch between the screw-shaft rotating plates is gradually reduced, the pressure on the sludge is also increasing, and the sludge begins to dehydrate under the action of pressure difference, and the water flows out from the filter gap between the fixed plate and the movable plate. At the same time, the equipment relies on the self-cleaning function between the fixed plate and the movable plate to clean the filter gap to prevent clogging. After sufficient dehydration, the mud cake is discharged from the discharge port under the push of the spiral shaft.
1. Screw-stacked sludge dewaterer, suitable for the concentration of 2000mg/l-5000mg/l, not only can treat high-concentration sludge, but also can directly concentrate and dehydrate low-concentration sludge. It has a wide range of sludge concentration, up to 2000mg/l-5000mg/l.
2. The movable fixed ring replaces the filter cloth, self-cleaning, non-clogging, easy to treat oily sludge. Under the rotating action of the spiral shaft, the movable plate moves steadily relative to the fixed plate, thus realizing the continuous self-cleaning process and avoiding the blockage problem commonly existing in the traditional dehydrator. Therefore, it has strong oil resistance, easy separation and no blockage.
3, automatic control, simple operation and management.
