Abstract

The invention provides a sludge dewatering device for sewage treatment. The sludge dewatering device for sewage treatment comprises an outer cylinder, a first inner cylinder, a separation component, awater pumping component and a first driving mechanism, the first inner cylinder is contained in the outer cylinder, the first inner cylinder is rotationally connected to the outer cylinder, a plurality of through holes are formed in the peripheral side of the first inner cylinder, and the separation component comprises a filter cloth wrapping the peripheral side of the first inner cylinder and aplurality of spiral blades fixed to the filter cloth. The water pumping component comprises a water pumping pipe, wherein one end of the water pumping pipe extends into the first inner cylinder, and the other end of the water pumping pipe extends out of the outer cylinder; and the first driving mechanism is fixed on the top of the outer cylinder to drive the first inner cylinder to rotate. Sludgeis separated from water under the action of centrifugal force, water enters the first inner cylinder through the filter cloth and the through holes, and the water in the first inner cylinder is pumpedout by a pumping pipe to realize sludge dehydration and improve dehydration efficiency.

Description

Technical field [0001] The invention relates to the field of mechanical equipment, in particular to a sludge dewatering device for sewage treatment. Background technique [0002] Sludge is an inevitable product of sewage treatment in sewage treatment plants and sewage stations. After the sludge that has not been well treated and disposed of enters the environment, it will directly cause secondary pollution to the water body and the atmosphere, and also affect the ecological environment and human activities. It will pose a serious threat. Therefore, the sludge is treated very carefully. The sludge can be divided into two types: sludge dewatering process and sludge drying process. The following mainly introduces different types of sludge dewatering machines. Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, e...
