A squeeze type sludge dewatering device

Abstract

The invention relates to a squeeze type sludge dewatering device, which solves the problems in the prior art that the water content of the mud cake cannot be ensured, the filter press efficiency is low, the work intensity is high, and the energy consumption is high; the technical solution is: comprising a drum , there is a rotating shaft in the drum, a first rotating block is arranged on the rotating shaft, a first extruding plate is arranged on the first rotating block, a second rotating block is arranged on the rotating shaft, and a second extruding plate is arranged on the second rotating block; There is an inner barrel with a liquid outlet hole on the inner barrel, a filter screen in the liquid outlet hole, a feed port on the drum, a rotating block on the drum, a through hole on the rotating block, a block on the rotating block, and a Block, there is a discharge port on the drum, a pressure switch on the discharge port, and a fixing device on the drum; the first extrusion plate is fixed, the second extrusion plate rotates, the sludge is squeezed, the inner drum rotates, and the rotary block rotates , the feed port is opened, the sludge enters, the discharge port is opened, and the sludge falls out; the inner barrel rotates and resets, the feed port is closed, the first extrusion plate rotates, and the second extrusion plate is fixed; it can realize the high efficiency of sludge dehydration.

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...
