High-precision large-flux belt-type filtration and concentration equipment based on filter cloth

Abstract

The invention relates to high-precision large-flux belt-type filtration and concentration equipment based on filter cloth, and relates to the technical field of concentrated mechanical equipment. The belt-type filtration and concentration equipment comprises a frame, a mud inlet, a filter device, a splash guard, a regulating plate and a bottom plate, wherein the filter device comprises a driving roller and a driven roller; the driving roller is connected with the driven roller through the filter cloth; a filter cloth tensioning mechanism and a filter cloth offset adjusting mechanism are also connected to the filter cloth; side-leakage-proof hold-down mechanisms are arranged on the left and right sides of the filter cloth; a mud turning mechanism is arranged above the filter cloth; a filter cloth support rack is arranged under the filter cloth; drainage openings are formed in the filter cloth support rack; a water receiving plate is arranged under the filter cloth support rack; a mud outlet is formed near the driving roller; a scraper plate is arranged above the mud outlet. The belt-type filtration and concentration equipment has the advantages of small size, good treating capability and high precision, and the operation method is easy to grasp.

Description

technical field [0001] The invention relates to the technical field of concentrating mechanical equipment, in particular to a belt-type filter concentrating device based on high-precision and large-throughput filter cloth. Background technique [0002] In the field of solid-liquid separation such as river dredging and dehydration, sludge dehydration in sewage treatment plants, and fiber slurry concentration in paper mills, due to the high moisture content of the initial slurry, directly entering the dehydration equipment will greatly reduce the processing capacity of the dehydration equipment. Before dehydration, the initial mud will be preshrunk to achieve the purpose of increasing the dehydration rate. At present, a sedimentation and concentration treatment method is usually adopted, such as building a relatively large sedimentation tank for concentration treatment, but this operation method has a fixed pre-shrinking site, a long pre-shrinking time, and poor flexibility. ...

AI Technical Summary

Problems solved by technology

At present, a sedimentation and concentration treatment method is usually adopted, such as building a relatively large sedimentation tank for concentration treatment, but this operation method has a fixed pre-shrinking site, a long pre-shrinking time, and poor flexibility. In the application occasions, such as river dredging, dehydration and drying mobile equipment, it is necessary to use a concentration equipment that requires a large operating load, a small footprint, a small volume, a light operating weight, and high processing accuracy. Filtration and concentration equipment meeting the above requirements
