Automatic desludger for filter press

Abstract

The invention discloses an automatic desludger for a filter press. The automatic desludger comprises frameworks and rotating mechanisms, wherein the frameworks are provided with side pipes and top pipes; one framework is arranged on each of two sides of a filtering plate; the frameworks are connected with filter cloth at the same side; adjacent top pipes of two adjacent filtering plates are connected; one rotating mechanism is arranged between the two frameworks of the same filtering plate; each rotating mechanism comprises a fixed plate and pipe sleeves; the fixed plates are fixed on two sides of each filtering plate; a notch is formed in each fixed plate; each pipe sleeve is arranged in the corresponding notch; the tail ends of the frameworks sleeve the inner parts of the corresponding pipe sleeves. The automatic desludger for the filter press, disclosed by the invention, has the advantages of simple and compact structure, reasonable design, as well as flexibility and convenience inuse; sludge can be cleaned quickly and effectively, the use efficiency of equipment is improved and labor intensity is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an automatic desilting device for a filter press. Background technique [0002] The filter press is to pressurize and dehydrate the sludge to make it a mud cake with low water content. The filter press has several filter plates and diaphragm plates placed at intervals, and filter cloth is wrapped on the filter plates and diaphragm plates. When the filter press presses the sludge, the filter plate and the diaphragm plate are attached to each other. When the filtration is finished, the filter plate is dragged piece by piece by the drag mechanism that comes with the filter press. The filter cloth on the diaphragm plate does not contain mudcake. The mud cake remains on the filter cloth on one of the two sides of the filter plate. Due to the stickiness between the mud cake and the filter cloth, the mud cake cannot fall off by itself. At present, the res...

Due to the stickiness between the mud cake and the filter cloth, the mud cake cannot fall off by itself

At present, the residual mud cake is mainly scraped off by hand-held scraping tools. This method has the following disadvantages: low operating efficiency; the thickness of the residual mud cake is inconsistent, and it is difficult to control the scraping when scraping the mud cake Removal efforts; high labor costs and rising operating costs have brought a lot of burden to the company; the harsh working environment has adversely affected the health of workers
