Abstract
The utility model discloses a kind of filter-plate structures of plate and frame type filter-press, it is inserted into special filter plate in filter plate and filter cloth constitute several groups filtering group, it is not provided with filter cloth on the special filter plate, it is located in special filter plate on external face and stock inlet is set, and the through-hole pipe of setting connection stock inlet is used for into slurry or air inlet on special filter plate.The utility model changes the working method of entire plate and frame type filter-press due to increasing special filter plate, into when slurry evenly, feed liquid separation is more abundant, shortens 4 hours mud extraction time, and the mud cake water content of formation is uniform, non-environmental-pollution, mud cake easily fall off, and outward transport is convenient.
Description
Technical field
The utility model is related to a kind of plate and frame type filter-press more particularly to a kind of filter-plate structures of plate and frame type filter-press.
Background technology
Plate and frame filter press constitutes one group of filter chamber by alternately arranged filter plate and filter frame.There is groove on the surface of filter plate, protrusion
Position is to supporting filter cloth.Have through-hole on the corner of filter frame and filter plate, complete channel constituted after assembling, can be passed through suspension,
Washings and extraction filtrate.Plate, frame both sides respectively have handle rest on crossbeam, by pressing device pressure plate, frame.Between plate, frame
Filter cloth play gasket seal.Suspension is pressed into filter chamber by charging pump, forms filter residue on filter cloth, until full of filter
Room.Filtrate passes through filter cloth and flow to sheet frame corner channel along filter plate groove, concentrates discharge.Filtering finishes, and can be passed through washing washing
Wash the filter residue on filter cloth.After washing, also needs to be passed through compressed air sometimes, remove remaining cleaning solution, then turn on filter press and unload
Except filter residue, filter cloth is cleaned, again pressure plate, frame, starts subsequent work cycle.
Since existing plate and frame type filter-press is all by the stock inlet in pressure filter thrust plate one end is arranged into slurry, liquid outlet
Drain, by multigroup filter plate and filter cloth, is gradually filled to the other end, what this structure generated asks from stock inlet into slurry by one end
There are many topic, mainly have：1, cake moisture is high, and the mud extraction time is long, and outward transport is difficult, seriously polluted.2, filter cake bonding can not fall off,
The labor intensity manually removed is big, is easy shovel and breaks filter cloth.3, filter cake is removed not clean, residue can be caused to harden, be filtered when putting into operation again
Cloth is easy breakage.
Utility model content
To solve the above problems, providing a kind of filter-plate structure of plate and frame type filter-press, which can shorten the utility model
The mud extraction time keeps the cake moisture to be formed uniform, and non-environmental-pollution, filter cake is easy to fall off, and outward transport is convenient.
The utility model in order to achieve the above objectives, is adopted the technical scheme that：A kind of filter plate knot of plate and frame type filter-press
Structure is inserted into special filter plate in filter plate and filter cloth constitute several groups filtering group, filter cloth is not provided on the special filter plate, special
Filter plate, which is located on external face, is arranged stock inlet, and on special filter plate the through-hole pipe of setting connection stock inlet be used for into slurry or into
Gas.
Further, the special filter plate is arranged several pieces, is distributed between filtering group.
Further, in the special filter plate at least one piece close to pressure plate be arranged.
Stock inlet on the special filter plate and the stock inlet on thrust plate are simultaneously into slurry, when into compressed air,
Air inlet simultaneously, inlet period are 6~9 hours.
The utility model has the beneficial effects that：Due to increasing special filter plate, the work of entire plate and frame type filter-press is changed
Make mode, into evenly, feed liquid separation is more abundant, shortens 4 hours mud extraction time, the mud cake water content of formation is uniform, nothing when slurry
Environmental pollution, mud cake easily fall off, and outward transport is convenient.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the special filter-plate structure schematic diagram of the utility model.
In figure：1, filtering group, 2, special filter plate, 3, stock inlet, 4, pressure plate, 5, thrust plate.
Specific implementation mode
As shown in Figure 1, 2, a kind of filter-plate structure of plate and frame type filter-press constitutes several groups filtering group 1 in filter plate and filter cloth
It is middle to be inserted into special filter plate 2, it is not provided with filter cloth on the special filter plate 2, is located in special filter plate 2 on external face and stock inlet is set
3, and the through-hole pipe of setting connection stock inlet is used for into slurry or air inlet on special filter plate 2.
The special filter plate 2 is arranged several pieces, is distributed between filtering group 1.
It is arranged close to pressure plate 4 at least one piece in the special filter plate 2.
Being arranged so as to of special filter plate allows feed liquid to be rapidly introduced into filter press, and pressure is balanced, from thrust plate to
Pressure plate is two ends, and simply from one end, affirmative pressure is difficult equilibrium, and even if being added in the middle part of filter press into slurry still
Optimum efficiency cannot be reached, be most preferred embodiment close to pressure plate setting therefore.
Stock inlet 3 on the special filter plate 2 and the stock inlet 3 on thrust plate 5 are simultaneously into slurry, into compressed air
When, while air inlet.
The inlet period is 6~9 hours.
Initial trial air inlet uses 8 hours, first time mud extraction, and aqueous 11.9, the slight foundry loam of filter cloth；Then it is small that 9 are increased to
When, it is aqueous to be down to 9.8, but filter cloth foundry loam is serious；Then it is down to 6 hours, discovery aqueous 14.8, the slight foundry loam of filter cloth, degree is low
In 8 hours.
It is preferred, therefore, that the inlet period is 6 hours.
Filter press is into slurry structure type at present：Slurries enter filter press by unique pulp-inlet pipeline；Filter press filter board
After group is compacted, slurries enter each filter element by filter press pulp-inlet pipeline, by every piece of filter plate centre bore, carry out filtrate point
From.This structure type has the following defects：Due to being determined into slurry structure into slurry only at one, cause in filter press into slurry, filter
Liquid detach when, close into slurry side filter cake it is thicker, filling filter pad chamber it is fuller, moisture content is relatively low, but with distance into
Slurry mouth gets over the filter plate of distant place, and for the filter cake of chamber than relatively thin, moisture content is larger.
The function of common filter plate can only carry out the filtrate separation of slurries, by the improvement to filter-plate structure, in filter plate sheet frame
Slurry-feeding hole is arranged in top, due to increasing special filter plate, changes the working method of entire plate and frame type filter-press, into when slurry more
Uniformly, feed liquid separation is more abundant, shortens 4 hours mud extraction time, the mud cake water content of formation is uniform, non-environmental-pollution, mud cake pole
Easy to fall off, outward transport is convenient.
The embodiment of the present application is only intended to illustrate that technical characteristic disclosed in the present application, those skilled in the art pass through simple
The change that is carried out of replacement, still fall within the range that the application is protected.
