Diaphragm-type filter press capable of mechanically and automatically falling off filter cake

Abstract

The invention discloses a diaphragm-type filter press capable of mechanically and automatically falling off a filter cake, which is characterized in that a plurality of sets of filter plates are stacked between a pressing plate and a thrust plate, and limiting sliding assemblies are arranged on two sides of the plurality of sets of stacked filter plates; filter grooves are formed in the two sides of the filter plates, filter cloth is installed in the filter grooves of the filter plates, filter cavities are formed by the filter cloth in the adjacent filter plates, and the filter cavities are communicated with the flow guide holes; a flow guide cavity formed between the filter plate and the filter cloth is communicated with a liquid outlet hole; a plurality of fixed bulges and a plurality of lifting bulges are fixedly arranged in the flow guide cavity of the filter plate, and the fixed bulges are fixedly connected with nozzles; and the plurality of lifting bulges are fixedly connected to the same extrusion plate, and a second pressurization pipeline communicated with a high-pressure channel is formed in the middle of the filter plate. According to the invention, the filter pressing effect is improved, the water content of the filter cake after filter pressing is low, the mechanical and automatic falling of the filter cake of the diaphragm-type filter press is realized, the labor intensity of workers is reduced, the working efficiency is improved, and the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the field of filter presses, in particular to a diaphragm type filter press with mechanical automatic filter cake shedding. Background technique [0002] Diaphragm filter press is a kind of equipment to realize the separation of solid and liquid in suspension in industrial production. It is widely used in coal washing, petroleum, chemical industry, medicine, food and other fields. Materials and other industrial wastewater and urban sewage treatment and other fields that require solid-liquid separation. The working principle of the diaphragm filter press is that a certain number of filter plates and filter cloths arranged between the plates are tightly arranged in a row under the action of strong mechanical force to form a filter press group, and a filter chamber is formed between the filter plate surfaces. , the filter slurry enters each filter chamber under the push of the feed pump, and the filter slurry is separated from so...
