Spiral sludge dewatering machine with good drying effect and use method of spiral sludge dewatering machine

Abstract

The invention provides a spiral sludge dewatering machine with a good drying effect and a use method thereof.The spiral sludge dewatering machine with the good drying effect comprises a workbench and a dewatering box arranged at the top of the workbench and further comprises a collecting box fixedly connected to the top of the workbench, and a first fixing device and a second fixing device are connected to the top wall of the collecting box; the air cylinder is fixedly connected to the outer wall of the dewatering box, the output end of the air cylinder penetrates through the dewatering box to be connected with an extrusion cleaning device, and the end, away from the air cylinder, of the extrusion cleaning device is connected to the top of the dewatering box; a filter plate matched with the cleaning end of the extrusion cleaning device is arranged in the dewatering box and is used for carrying out secondary dewatering on the sludge; the sludge dewatering device is simple in structure and convenient to operate, the dewatering and drying effect of the device is greatly improved, the water content of sludge is effectively reduced, the phenomenon that sludge is blocked in the dewatering device is avoided, and silt is conveniently discharged.

Description

technical field [0001] The invention relates to the field of sludge dewatering equipment, in particular to a spiral sludge dewatering machine with good drying effect and a use method thereof. 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 the moisture content of sludge is lower than 50% to meet the requirements of incineration, it will cost a lot of money. Therefore, almost all s...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is: the dehydration and drying effect of the existing device is not good, the water content of the sludge after treatment is still high, and the work efficiency is low; if it is used for a long time, sludge congestion is likely to occur inside the dehydrator, which is inconvenient The discharge of sediment will affect the subsequent dehydration operation; the device is not convenient for compression molding of the dewatered sludge, and it is difficult to realize continuous operation
