Plate-frame type anti-blocking sludge dewatering machine with long service life

Abstract

The invention relates to a plate-frame type anti-blocking sludge dewatering machine with long service life. The dewatering machine comprises a conveying mechanism, a pressing mechanism, a water tank,a controller, a cleaning mechanism and a dewatering mechanism; the conveying mechanism comprises a hopper, a material pipe, an oblique tube and a cleaning room, the dewatering mechanism comprises a frame, a stencil, filter cloth, two rotating assemblies and four supporting assemblies, and the cleaning mechanism comprises a water pump, a moving tube, a second filter screen, two translation assemblies and a plurality of nozzles. According to the dewatering machine, sludge is transported through the conveying mechanism, large debris is isolated by a first filter screen to prevent the filter clothfrom being scratched and damaged when the sludge is squeezed, the service life of the filter cloth is ensured, the sludge flows smoothly, the debris on the first filter screen is removed in time through a cleaning assembly, the filter cloth is turned over under the driving of a first motor, the filter cloth is washed and cleaned by the cleaning mechanism to prevent the sludge from adhering to thefilter cloth to cause blockage, and the smooth progress of subsequent sludge dewatering is ensured.

Description

technical field [0001] The invention relates to the field of environmental protection testing equipment, in particular to a plate and frame sludge dehydrator with long service life and anti-clogging. Background technique [0002] Sludge is an inevitable product after treatment in sewage treatment plants and sludge stations. Untreated sludge entering the environment will directly cause secondary pollution to water bodies and the atmosphere, and will also affect the ecological environment and human activities. Therefore, people usually use sludge dewatering machines for sludge treatment. Among various sludge dewatering machines, plate and frame sludge dewatering machines are widely used. Its working principle is that in a closed Under normal conditions, the injected sludge is squeezed by the plate frame, so that the water in the sludge is discharged through the filter cloth to achieve the purpose of dehydration. It has the advantages of simple structure, easy operation, stable...

AI Technical Summary

Problems solved by technology

[0003] However, during the operation of the existing plate and frame sludge dewatering machine, since the sludge contains relatively hard large substances such as stones, metal objects, and branches, these hard substances are easy to scratch the filter during the process of squeezing the sludge. Cloth will damage the filter cloth and reduce the service life of the filter cloth. Not only that, after squeezing, some sludge will remain on the surface of the filter cloth. The circulation is not smooth, which affects the subsequent sludge dewatering operation, thereby reducing the practicability of the existing plate and frame sludge dewatering machine
