Thickening and dewatering filter

Abstract

The invention discloses a thickening and dewatering filter comprising an upper cavity and a lower cavity and being characterized in that a meshed pore plate is arranged between the upper cavity and the lower cavity; the upper cavity, the meshed pore plate and the lower cavity are fixedly connected to form an integrated structure; filter cloth is arranged on the meshed pore plate; two opposite sides of a connection part of the upper cavity and the meshed pore plate are provided with side holes; the filter cloth extends out of the side holes; a sealing bracket is arranged out of the upper cavity; a sealing bar is arranged on the sealing bracket; the sealing bar corresponds to the side wall of the upper cavity and the side holes; and a compacting cylinder is connected to the sealing bracket. Compared with the prior art, the thickening and dewatering filter provided by the invention is composed of the integrated upper cavity and lower cavity, namely the upper cavity and the lower cavity are integrated, the meshed pore plate is used as a demarcation line between the upper cavity and the lower cavity, and the pressures in the cavities are controlled by the sealing bracket arranged at the side, so that the thickening and dewatering filter has the following advantages that control elements are reduced, the equipment structure is simpler and is optimized, the filter is convenient to operate, and meanwhile, the purposes of energy saving and emission reduction are achieved.

Description

technical field [0001] Concentrated dehydration filter is widely used in the filtration of cooling lubricant (oil) in high-precision machining processes such as steel rolling, grinding, and grinding, so as to improve the processing technology, improve the surface processing quality of workpieces, and prolong the service life of cooling lubricant (oil) , and can also be used in the field of environmental protection. The invention provides a concentrated dehydration filter with improved structure. Background technique [0002] The concentrated dehydration filter is a new type of filtration product. It uses a recirculating filter belt as the medium to arrange the sewage on the filter medium, and makes full use of the gravity of the sewage itself and the positive pressure difference between the upper and lower chambers to achieve solidification. Liquid separation, the dirty liquid accelerates through the filter medium to form a filter cake, and then the filter cake also partici...

AI Technical Summary

Problems solved by technology

[0003] The structural characteristics of the existing concentration dehydration filter are: the upper and lower chambers are separated, and the upper and lower chambers are generally compressed and sealed by the movement of air bags or hydraulic cylinders. The disadvantages are complex structure, cumbersome operation steps, and high production costs.
