Rotary extrusion type filter

Abstract

The invention provides a rotary extrusion type filter which comprises screen supporting wheels, screens, a filtering channel, a shell, an inner interval wheel, a deflecting plate, a reducer, a motor, a muddy material inlet and a filter residue outlet, wherein the screen supporting wheels are positioned on the outer sides of the screens; the filtering channel is positioned in the screens; the shell is positioned at the upper end of the filtering channel; the inner interval wheel is positioned at the lower end of the filtering channel; an outlet of the filtering channel is provided with a flashboard; the inner interval wheel is fixedly connected with the screen supporting wheels; the screen supporting wheels comprise a first screen supporting wheel and a second screen supporting wheel; the screens comprise a first screen and a second screen; the first screen supporting wheel is fixedly connected with the first screen; the second screen supporting wheel is fixedly connected with the second screen; and the shell and the deflecting plate are integrally molded. According to the rotary extrusion type filter, the production cost of the rotary extrusion type filter can be reduced, the service life of the rotary extrusion type filter is prolonged, the energy consumption is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machinery for dehydrating various municipal sludge, paper mill sludge, food industry muddy slurry, pharmaceutical industry muddy slurry, and chemical industry muddy slurry, in particular to a solid-liquid dehydration method for sludge-like fluids. Separate rotary squeeze filter. Background technique [0002] There are many kinds of solid-liquid separation machines for dehydrating various municipal sludge, paper mill sludge, food industry muddy slurry, pharmaceutical industry muddy slurry, and chemical muddy slurry, mainly including centrifuge, plate and frame type Filter press, belt filter. The rotary extrusion filter is a relatively late solid-liquid separation machine. Compared with the centrifuge, the rotary squeeze filter has the advantages of low energy consumption and less maintenance; compared with the belt filter, the rotary squeeze filter has the advantage of good airtightness.

Problems solved by technology

In the prior art, the outer partition plate is very thick, and the left and right shells are also very heavy. The fixation of the outer partition plate and the left and right shells and the fixing method of the deflection plate and the left and right shells make the structure of the machine very complicated. In the prior art, the deflection plate is as follows: If it is not firmly fixed to the left and right shells, the deflection plate will rub against the inner partition plate, which will increase the torsional load of the reducer and motor, and increase energy consumption
