Sludge concentrating filter belt mechanism

Abstract

The present invention relates to a sludge concentration mechanism, particularly to a sludge concentrating filter belt mechanism, and belongs to the technical field of environmental protection equipment. The mechanism comprises a housing, left and right sides of the housing are respectively provided with a driving roller and a driven roller, a concentrating filter belt is sleeved between the driving roller and the driven roller, and a sludge feed inlet is formed in the housing and positioned on one side of the driven roller. A rectifying mechanism is mounted on the concentrating filter belt, and tightly compresses the concentrating filter belt. A washing nozzle is mounted at the lower end of the concentrating filter belt, and the driven roller is provided with a tensioning mechanism. The sludge concentrating filter belt mechanism provided by the present invention is simple, compact and reasonable in structure, and operates stably and reliably. The filter belt can sufficiently concentrate the water content in the sludge, improves the dehydration efficiency and the dehydration quality of the sludge, and reduces the running costs.

Description

technical field [0001] The invention relates to a sludge thickening mechanism, in particular to a sludge thickening filter belt mechanism, which belongs to the technical field of environmental protection equipment. Background technique [0002] With the development of social economy and the acceleration of urbanization, the amount of urban sewage treatment plants and the accompanying sludge has increased rapidly. According to relevant materials, in 2010, the sludge produced by my country's sewage treatment plants reached 300 million tons. Since the sludge must undergo biochemical and flocculation treatment during dehydration, and the dehydrated sludge contains a large amount of cell water and attached water, at present, almost all the existing equipment and technologies of sewage treatment plants can only reduce the water content of sludge to About 80%, if you want to meet the requirements of incineration - the water content of the sludge is lower than 50%, it will cost a lo...

AI Technical Summary

Problems solved by technology

This sludge treatment method, firstly, requires a large investment in equipment, takes up a large space, consumes a lot of energy, and has high operating costs; secondly, the existing sludge thickening device is prone to blockage, resulting in low work efficiency and high operating costs. Limited effect on sludge thickening

In recent years, some people have also reported the concentration and dehydration integrated machine, but the treatment effect of the existing concentration and dehydration integrated machine is significantly lower than that of the traditional concentration and dehydration device.
