Abstract
The utility model provides a powerful sludge dewaterer. The utility model comprises a plurality of parallel plates which can move relatively forward and backward along the arraying direction. The dewaterer is equipped with a hydraulic compacting mechanism for pressing a plurality of plates. Some or all of the plates are equipped with a hydraulic oil chamber which can be filled with oil and a press plate driven by the hydraulic pressure from the oil chamber. The press plate faces to the neighboring plate, the plate surface at the side of the press plate and the neighboring plate surface facing to the press plate are equipped with a filter cloth respectively. The periphery of the plates is in the seal coordination when the plates are pressed tightly. The plates are equipped with a sludge convey channel and a filtrate outflow channel. By using the hydraulic oil chamber as the power source for the sludge dewatering, the dewatering pressure can reach 3 to 5 Megapascal per square centimeter, the squeezing force is greater than that of the plate and frame filter, the drum centrifuge and the belt filter press, which greatly promote the squeezing efficiency, reduce the sludge water content to below 45 percent, moreover, the utility model has the higher sludge treatment productivity and is suitable for the processing requirement of the municipal sewage sludge.
Description
Technical field
