Problems solved by technology

[0003] The traditional sludge dewatering device is relatively large in size and complex in structure. For example, the centrifugal dewatering machine has a relatively high rotation speed and high noise. In addition, the filter screen of the traditional dewatering device is easy to be blocked and needs to be cleaned frequently, and the dehydration efficiency is not high.

Abstract

The invention relates to a sludge dewatering machine, in particular to a stacked spiral type sludge dewatering machine which comprises a stirring flocculation device and a dewatering device. The dewatering device comprises a first sludge inlet, a first sludge outlet, a stacked spiral body, a support plate, a spiral shaft, a rack and a first power device. The stacked spiral body comprises fixed rings and movable rings. The fixed rings are fixedly connected with the support plate. The spiral shaft is located in a cylindrical cavity formed by the fixed rings and the movable rings. The spiral shaft is fixedly connected with the first power device. The support plate and the spiral shaft are fixed to the rack. By the adoption of the structure, the sludge dewatering machine is not prone to being blocked, the dewatering rate is increased, and operation is very convenient.

Description

technical field [0001] The invention relates to a sludge dewatering machine, in particular to a screw stacking sludge dewatering machine. 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. would pose a serious threat. Therefore, the sludge treatment is very cautious. Sewage will produce a large amount of sludge after sedimentation treatment. Even after concentration and digestion treatment, the water content is still as high as 96%. The area occupied by mud piles. [0003] The traditional sludge dewatering device is relatively large in size and complex in structure. For example, the centrifugal dewatering machine has a relatively high rotation speed and high noise. In addition, the filter screen of the trad...
