Improved sludge vacuum dehydration device

Abstract

The invention discloses an improved sludge vacuum dehydration device. The device comprises a box, wherein a mud pump is arranged on the box, a mud inlet pipe is connected to the mud pump, a mud outletpipe is connected to the mud pump, the mud outlet pipe is inserted into the box, a conveying device is arranged in the box and comprises a rack and a conveying belt, the conveying belt comprises a belt body and filter cloth, the filter cloth is bonded to the belt body, the belt body is provided with multiple groups of air holes, the multiple groups of air holes are uniformly distributed on the belt body, the conveying belt is provided with a connecting pipe in a contact mode, the connecting pipe and the conveying belt are in sealing contact, the connecting pipe is connected with a buffer box,the buffer box is connected with a vacuum pump through an air pipe, the right side of the rack is fixedly connected with an L-shaped connecting rod, and one end of the L-shaped connecting rod is fixedly connected with a scraping component. The device is high in dehydration efficiency, low in cost, small in working strength and extremely convenient to use, and less auxiliary equipment is adopted.

Description

technical field [0001] The invention relates to the technical field of sludge dewatering, in particular to an improved sludge vacuum dehydration device. Background technique [0002] With the continuous increase of domestic sludge production, the rapid and effective treatment of sludge is urgent. Before sludge treatment, sludge dehydration is required. After dehydration, the moisture content of sludge can be reduced to 55%. Up to 80%, depending on the nature of the sludge and sediment and the efficiency of the dewatering equipment. The further dehydration of sludge is called sludge drying, and the moisture content of dried sludge is less than 10%. [0003] The dehydration treatment of sludge generally adopts filtration method, and the equipment used in filtration method includes vacuum filter, plate and frame filter press and belt filter. The vacuum filter continuously enters mud and continuously discharges mud, and operates smoothly, but there are many auxiliary facilitie...

AI Technical Summary

Problems solved by technology

Manually operated plate and frame filter presses are very labor-intensive, and most of them are replaced by mechanical automatic operations. Therefore, it is necessary to design a sludge dewatering device with high dehydration efficiency and low operating costs.
