A rubber belt filter

Abstract

The invention provides a rubber belt filter. The filter comprises a support, a feeding device, filter cloth, a rubber belt, vacuum filtration boxes and a refuse vessel. The support is provided with vertical columns used for supporting the rubber belt horizontally arranged; the filter cloth is arranged above the rubber belt in parallel; both ends of the filter cloth are respectively provided with the feeding device and the refuse vessel; the vacuum filtration boxes are arranged below the rubber belt. The rubber belt filter has the improvements that a supporting plate is horizontally arranged between the vertical columns and the rubber belt; supporting seats are vertically arranged on the supporting plate at intervals; thermal insulation water is injected between the supporting plate and the supporting seats; the rubber belt is supported through the supporting seats and the thermal insulation water. Compared with the prior art, the rubber belt filter provided by the invention has the advantages that the flow rate of filter liquor is increased; the condition that channels are blocked due to the fact that the filter liquor scales is avoided; material crystallization and filter liquor scaling caused by the fact that environment temperature is reduced are avoided.

Description

technical field [0001] The invention relates to a filter, in particular to a rubber belt filter. Background technique [0002] The rubber belt filter is a machine that separates liquid and solid by vacuum suction. When the rubber belt filter is separated from the solid and liquid, the liquid is sucked under the filter cloth by vacuum suction, the solid is trapped on the filter cloth by the filter cloth, and the sucked filtrate flows through the rubber belt, and the suction converges to the There is only one vacuum suction filter box in the center of the whole machine, and then it is discharged through the liquid discharge device, and the solid filter residue is washed and dried and then discharged into the slag hopper. [0003] The main flow channels of the filtrate of traditional rubber belt filters, such as rubber belts and vacuum filter boxes, are installed in a horizontal state, which is prone to crystallization and scaling. After crystallization and fouling, the chann...

AI Technical Summary

Problems solved by technology

During solid-liquid separation and filtration, many materials are prone to crystallization and scaling due to the influence of low temperature, making it difficult to filter. Filter cloths and vacuum filter boxes are prone to scaling and clogging and cannot be filtered, especially in winter and northern regions.
