Abstract

A membrane-type press filter comprises a filter plate, a press plate, a rubber grid plate and filter cloth, wherein the left surface and the right surface of the filter plate are provided with grooves and are paved with the filter cloth; the upper end of the filter plate is provided with a feeding passage, and the lower end is provided with a liquid flowing hole; the lower parts of both surfaces are provided with slots; the lower part of the rubber grid plate is provided with a slot, and the lower part of the press plate is provided with an air inlet hole; the left surface and the right surface of the press plate are respectively provided with a groove; the shape of the rubber grid plate is matched with that of the press plate and is arranged on the surface of the press plate; one surface of the rubber grid plate is provided with a small prejection; and the other surface is paved with the filter cloth. The utility model has the advantages that the press plate is only provided with one groove, and the shape of the rubber grid plate is matched with that of the surface of the press plate. Thus, the impact and the abrasion of the rubber grid plate and the filter cloth are reduced, the service lives of the rubber grid plate and the filter cloth are prolonged, and the space of the filter cavity of the press filter is increased; because the small prejection is arranged on the rubber grid plate, the impact force between the rubber grid plate and the press plate is reduced, and thus, the work noise of the press filter is obviously lowered. In addition, the use cost is lowered, the production efficiency is increased, and the noise pollution is reduced.

Description

A kind of membrane type press filter
Technical field
The utility model relates to a kind of equipment for separating liquid from solid, particularly a kind of membrane type press filter.
Background technology
Present membrane type press filter is extensively adopted by industries such as chemical industry, fermentation, environmental protection, and as the capital equipment of Separation of Solid and Liquid, its result of use is also more satisfactory.As shown in Figure 1, prior art adopts following technical scheme mostly: it comprises frame, filter and hydraulic system, frame comprises fixed seal head, movable end socket, sliding pull bar, hydraulic system comprises hydraulic press and pumping plant, filter comprises more than one identical filter element, and described filter element comprises filter cloth, rubber grid plate, pressing plate, filter plate.Left and right two surfaces of described filter plate are provided with more than one cavity, and top is provided with a feeding-passage; Correspondingly, on left and right two surfaces of described pressing plate with respect to filter plate on the position of cavity also be provided with more than one cavity, described rubber grid plate has with the clamp surface shape adapting and is arranged at about described pressing plate on two surfaces, is provided with filter cloth on the surface of rubber grid plate and filter plate.Hydraulic machine piston bar promotion activity end socket, clamping platen and filter plate, pressing plate, filter plate and fixed seal head form an airtight filtering container.Be filtered material in the feeding-passage on filter plate top is imported each filter chamber of this container, the solid content that is filtered in the material just is retained in the filter chamber by filter cloth, and liquid then passes the groove of filter cloth along rubber grid plate and filter plate, discharges by fluid hole.After being filtered material input and finishing, feed compressed air, force rubber grid plate to be heaved, be filtered liquid remaining in the material, reach the effect of filtration thereby further squeeze out towards the cavity of filter plate by the air admission hole of fixed seal head bottom.
But still there is very big defective in present membrane type press filter, be exactly it in use for some time, the rubber grid plate of using as film, under the intact situation of rubber grid plate at the cavity position that is in filter plate, be in the rubber grid plate of the boss of filter plate, because all will contact with the boss of pressing plate in each work period, the rubber grid plate that is between two boss of filter plate and pressing plate will be subjected to very big impact, frictional force, so its very likely very fast breakage.Though just local damage even the monoblock rubber grid plate does not also use under the situation of degree of aging, also can not continue to use again, just need to change this rubber grid plate, shorten its service life greatly, cause huge waste.Equally, the filter cloth that is between two boss of filter plate and pressing plate also is easy to brokenly, and also must change.Like this, just increased user's use cost.Because pressing plate is provided with more than one groove, that is a plurality of boss are arranged on it, has correspondingly dwindled the filtering chamber space, has reduced production efficiency.Also have, a last work period finishes, and when needing emptying filtering chamber before carrying out next cycle, rubber grid plate will produce collision with pressing plate, makes the filter press work noise strengthen.
Summary of the invention
Technical problem to be solved in the utility model is is provided at above-mentioned prior art present situation a kind of service life that can prolong rubber grid plate and filter cloth, increases the filtering chamber space, reduces the membrane type press filter of noise.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of membrane type press filter, comprise filter, and described filter comprises filter element, described filter element comprises filter plate, pressing plate, rubber grid plate and first filter cloth; Described filter plate all is provided with groove on left and right two surfaces, and two surfaces all are equipped with described first filter cloth, and the filter plate upper end is provided with a feeding-passage, and the lower end is provided with a fluid hole, and the bottom on left and right two surfaces of described filter plate all is provided with groove; Described pressing plate bottom is provided with an air admission hole; On described rubber grid plate, be provided with groove towards the bottom on the surface of filter plate, it is characterized in that: on two surfaces about described pressing plate, with the corresponding position of filter plate upper groove a groove is set, pressing plate two surfaces are provided with described rubber grid plate, and described rubber grid plate has and the clamp surface shape adapting; The edge of described rubber grid plate is connected with pressing plate.
On the described rubber grid plate, be equipped with second filter cloth towards the surface of filter plate; Groove on the described filter plate is more than one; Described filter element is more than one; The connected mode of the described filter plate and first filter cloth, rubber grid plate and second filter cloth is adhered; Described rubber grid plate adopts hasp type to be connected with pressing plate or is spirally connected.
In order to reduce the impulsive force of pressing plate and rubber grid plate, increase the service life of rubber grid plate, can described rubber grid plate on, be provided with small embossment towards the surface of pressing plate; Described small embossment is regularly arranged.
Compared with prior art, advantage of the present utility model is, because whole pressing plate two surfaces all only are provided with a groove separately in the utility model, and rubber grid plate has and the clamp surface shape adapting, just make first filter cloth on second filter cloth, filter plate surface on rubber grid plate and its surface when the utility model is worked, only contact the boss on filter plate surface, reduce impact, wearing and tearing when their two boss that are original suffered, that come from filter plate and pressing plate are converged, prolonged the service life of rubber grid plate and two filter clothes; Because whole pressing plate two surfaces all only are provided with a groove separately, remove original boss position simultaneously, just made the space of filter press filtering chamber increase, made the treating capacity of each work period also increase thereupon; And, reduced the impulsive force between rubber grid plate and the pressing plate owing to be provided with regularly arranged small embossment on the rubber grid plate, make the filter press work noise obviously reduce.In a word, the utility model had both reduced user's use cost, had improved its production efficiency again, the pollution from environmental noise when also having reduced work.
