Rubber belt type vacuum filter

Abstract

The invention belongs to the technical field of filters, and discloses a rubber belt type vacuum filter which comprises a rubber belt conveying assembly, a filter belt conveying assembly, a filter belt cleaning assembly and a modular vacuum disc. The rubber belt conveying assembly comprises a driving roller, a driven roller and a conveying belt. The filter bag conveying assembly comprises a guide roller, a limiting roller and a filter belt, and the filter belt is of an annular structure and is flatly laid and arranged on the outer surfaces of the driving roller, the driven roller and the guide roller in a surrounding mode; the limiting roller is limited between the guide roller and the driving roller and is in contact with the outer surface of the filter belt; the driven roller, the guide roller and the limiting roller are matched with one another, so that the filter belt below the driven roller forms a V-shaped structure; the filter belt cleaning assembly is arranged between the guide roller and the limiting roller, and the filter belt cleaning assembly comprises a flushing device arranged on the inner side of the filter belt and a cleaning roller arranged on the outer side of the filter belt; and the modular vacuum disc is formed by combining a plurality of single discs and arranged in the annular conveying belt.

Description

technical field

[0001] The invention belongs to the technical field of filters, in particular to a rubber belt vacuum filter. Background technique

[0002] The rubber belt vacuum filter is a belt vacuum filter with an annular rubber belt as the transmission mechanism. The main filter medium of the rubber belt vacuum filter is filter cloth. When the rubber belt vacuum filter is running, the filter cloth is spread on the ring rubber. Driven by the motor, the two move together to complete the filtration and dehydration. But still there is certain deficiency for existing rubber belt type vacuum filter, for example:

[0003] 1) The overall machine is large in size and complex in structure, which is inconvenient for transportation, installation and maintenance;

[0004] 2) After the existing rubber belt vacuum filter is used for a long time, more residues will be attached to the filter belt, which will cause the filter belt to be blocked and affect the filtering effect; The bel...
