Pressure-adjustable belt filter press

Abstract

The invention discloses a pressure-adjustable belt filter press. The pressure-adjustable belt filter press comprises a rack, a drive mechanism, a press-filtering mechanism, a pressure adjusting mechanism, shaft distance compensating mechanisms, a filtering belt deviation rectifying mechanism and a filter belt back flushing mechanism. The press-filtering mechanism comprises an upper filtering belt ring formed by a plurality of rollers and a lower filtering belt ring formed by a plurality of rollers. A material inlet and a material outlet are formed between the upper filtering ring and the lower filtering ring. The exterior of the upper filtering belt ring is sleeved with an upper filtering belt, and the exterior of the lower filtering belt ring is sleeved with a lower filtering belt. The pressure adjusting mechanism comprises a floating roller, a bearing pedestal, a sliding block, a hydraulic oil cylinder, wherein the floating roller is pressed onto the inner side of the upper filtering belt. Each shaft distance compensating mechanism comprises a compensating roller, a bearing pedestal, a sliding block and an air cylinder. The upper filtering belt ring and the lower filtering belt ring are provided with the shaft distance compensating mechanisms respectively. The compensating roller in the upper filtering belt ring is pressed onto the inner side of the upper filtering belt, and the compensating roller in the lower filtering belt ring is pressed onto the inner side of the lower filtering belt. The pressure-adjustable belt filter press has the advantages that pressure can be adjusted conveniently, and it is guaranteed that materials do not penetrate through filtering cloth.

Description

technical field [0001] The invention relates to a filter press, in particular to a pressure-adjustable belt filter press. Background technique [0002] Filter press is a commonly used solid-liquid separation equipment. It was used in chemical production in the early 18th century and is still widely used in chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and environmental protection industries. [0003] It is inconvenient to adjust the pressure of the filter press in the existing filter press. It cannot work when the material is pressed through the filter cloth. Not convenient enough to use. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a pressure-adjustable belt filter press for the deficiencies of the prior art. [0005] In order to achieve the above object, the measures taken by the present invention: [0006] A pressure-adjustable belt filter press, comprising a frame, a drive mec...
