Extrusion type sludge dewatering device

Abstract

The invention relates to an extrusion type sludge dewatering device, and solves the problems that the water content of mud cakes cannot be ensured, the filter pressing efficiency is low, the working strength is large, and the energy dissipation is high in the prior art. According to the technical scheme, the extrusion type sludge dewatering device comprises a drum, wherein the drum is internally provided with a rotating shaft, the rotating shaft is provided with a first rotating block, the first rotating block is provided with a first extrusion plate, the rotating shaft is provided with a second rotating block, and the second rotating block is provided with a second extrusion plate; the drum is internally provided with an inner bucket, the inner bucket is provided with liquid outlet holes,each liquid outlet hole is internally provided with a filter net, the drum is provided with a feed port, the drum is provided with a rotating block, the rotating block is provided with through holes,the rotating block is provided with clamping blocks, the inner bucket is provided with a check block, the drum is provided with a discharge port, the discharge port is provided with a pressure switch, and the drum is provided with a fixing device; the first extrusion plate is fixed, the second extrusion plate rotates to extrude sludge, the inner bucket rotates, the rotating block rotates, the feed port is opened, the sewage enters into the feed port, the discharge is opened, and the sewage falls off; the inner bucket rotates and resets, the feed port is closed, the first extrusion plate rotates, and the second extrusion plate is fixed; efficient dewatering of the sludge can be achieved.

Description

technical field [0001] The invention relates to the field of sludge treatment machinery, in particular to an extruding sludge dewatering device. Background technique [0002] Sludge is an inevitable product of sewage treatment in sewage treatment plants and sewage stations. Untreated sludge entering the environment will directly bring secondary pollution to water bodies and the atmosphere, and it will also affect the ecological environment and human activities. It will pose a serious threat. When dealing with sludge, dehydration must be carried out first; the existing dehydration process is generally dewatered by pressure filtration, but the working pressure in the pressure filtration process is unstable, and the operation of the delivery pump can be realized solely by the experience of the operator. Start and stop, and valve opening and closing, which are not conducive to energy saving and consumption reduction, and at the same time cannot ensure the moisture content of the...
