Compared with the prior art, the filter press disclosed by the invention is good in sealing property, free from leakage and excellent in filtering effect.

Description

Filter press
Technical field
The present invention relates to solid-liquid separation mechanics equipment technical field, especially a kind of filter press produced for lithopone.
Background technology
Filter press is a kind of low power consuming, the intermittent pressure filtration facility of high efficiency, for various slurry Separation of Solid and Liquid, rely on hold down gag to be compressed by filter plate, again by slurry with being pumped into filter chamber, reach solid particle and fluid separation applications by filter cloth, because its filter area is large and efficiency advantages of higher, and be widely used.Existing filter press mainly comprises frame, crossbeam, thrust plate, the oil gear of band pressure strip and multiple filter plate, filter frame and filter cloth, frame is fixed with two crossbeams, crossbeam is alternately arranged with multiple filter plate and filter frame, filter cloth is separated with between filter plate and filter frame, four angles of filter plate and filter frame are equipped with through hole, and the center of filter plate starts there is charging aperture.There is following deficiency in the filter press of this structure: poor sealing performance, and slurries easily spill between gap from filter plate and between filter frame and filter cloth, and the leakage slurries in these places can enter in the feeder of below, and reduce filter effect.
Summary of the invention
The object of this invention is to provide a kind of filter press, this filter press can solve the problem of existing filter press poor sealing performance.
In order to solve the problem, the technical solution used in the present invention is: this filter press comprises frame, crossbeam, thrust plate, oil gear with pressure strip and filter plate and filter cloth, described frame is fixed with two described crossbeams, described crossbeam upper bracket has multiple described filter plate, filter cloth is separated with between adjacent described filter plate, described filter plate and described filter cloth all offer centre bore, four limits of described filter plate extend to two sides protrudes the convex frame of formation, a described convex frame wherein side is provided with ring rib, another side is provided with annular groove, the described ring rib of described convex frame and the described annular groove tabling of adjacent described convex frame, four angles of described convex frame are equipped with through hole, described through hole be all positioned at ring rib around within scope, at least one side of described filter plate is provided with described filter cloth, the outward flange of described filter cloth is pressed on described filter plate by exterior deckle board, the centre bore inward flange of described filter cloth is pressed on described filter plate by inner ring plate, and described exterior deckle board is all connected with described filter plate by securing member with described inner ring plate.
In the technical scheme of above-mentioned filter press, technical scheme can also be more specifically: the centre bore periphery in described filter plate on described filter plate is provided with annular boss.
Further, two sides of described filter plate are all provided with described filter cloth.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, good airproof performance, ne-leakage; Filter plate four limit stretches out to protrude and forms convex frame, eliminate the gap of filter plate and convex frame, and the convex frame on two sides is respectively equipped with ring rib and annular groove, when can make that filter plate is compacted to be drawn close, ring rib and the annular groove of the convex frame of adjacent filter plate are just in time fitted together to, thus prevent outside seepage.
2, filter cloth is firmly fixed on filter plate by pressing plate, and filter cloth is not subjected to displacement, and ensure that the working face of filter cloth is smooth, and can prevent slurry from directly entering between filter cloth and filter plate from charging hole, improves filter effect.
