Abstract
The utility model relates to a filter pressing board, which comprises a filter board, a feed inlet, a washing water inlet and a filter liquid outlet. The utility model is characterized in that the circumference of the filter board is provided with elastic pads, the cross section of the elastic pad is a middle convex shape, the maximum thickness of the elastic pads at least is 8 mm, and the elastic pads adopt compressible elastic materials with good recoverability. The utility model has the advantages of simple structure, convenient processing and convenient installation. The utility model can effectively reduce cost and can obviously reduce the moisture contain rate of filter cakes.
Description
The utility model relates to filter, mainly is a kind of Filter pressing board.
In the prior art, filter plate comprises membrane filter plate 3 ', charging aperture 8 ', washing water inlet 9 ' and filtrate (liquid 10 ', barrier film 4 ' covers the surface of whole membrane filter plate 3 ', charging aperture 8 ' locates also will be provided with outer screwed pipe 1 ' and charging aperture volution 2 ' seals, filtrate (liquid 10 ' locates to be provided with filtrate (liquid volution 6 ' and perforated lid 5 ' seals, if further reduce rate of cake moisture content, then to adopt compressed air to blow bulging diaphragm of rubber and could realize.The deficiency of this structure is: complex structure, processing are installed all inconvenient, thereby cost is higher, and sealing device is fragile, keeps in repair very inconvenient.
The utility model is in order to overcome above-mentioned deficiency, and a kind of Filter pressing board is provided.It is simple in structure, and processing is installed convenient, can effectively reduce cost and can reduce the moisture percentage of filter cake significantly.
The purpose of this utility model is achieved through the following technical solutions.This Filter pressing board comprises filter plate, charging aperture, washing water inlet and filtrate (liquid, it is characterized in that being provided with elastic insert around filter plate, and the cross section of elastic insert is the shape of intermediate projections.
The purpose of this utility model can also be come further perfect by the following technical programs.The maximum ga(u)ge of elastic insert is at least 8mm, and that elastic insert adopts is compressible, restorability elastomeric material preferably.
The utility model has the advantages that: owing to being provided with elastic insert around the Filter pressing board, the sealing device that does not need barrier film and clamping barrier film, greatly reduce production cost, because the cross section of elastic insert is the shape of intermediate projections, and adopt compressible, restorability elastomeric material preferably, thereby under the situation that increases crush, can reduce the moisture percentage of filter cake significantly.
Fig. 1 is the filter plate master TV structure schematic diagram of prior art.
Fig. 2 is the filter plate A-A sectional structure schematic diagram of prior art.
Fig. 3 is a main TV structure schematic diagram of the present utility model.
Fig. 4 is a sectional structure schematic diagram of the present utility model.
Fig. 5 is an operation principle structural representation of the present utility model.
The utility model will be further described below in conjunction with embodiment.This Filter pressing board comprises filter plate 3, charging aperture 8, washing water inlet 9 and filtrate (liquid 10, is provided with elastic insert 4 around filter plate 3, and the cross section of elastic insert 4 is the shape of intermediate projections.The maximum ga(u)ge of elastic insert 4 is 12mm, and that elastic insert 4 adopts is compressible, restorability elastomeric material preferably.Whole system comprises thrust plate 12, a plate 13, filter plate, filter cloth 14, tailgate 15, pressure strip 16, crossbeam 17, hydraulic cylinder 18, cylinder seat 19, Hydraulic Station 20, drawing-plate mechanism 11 and varicose mechanism 21 etc.Wherein filter plate is totally 5, and 3 of Filter pressing boards are established a common filter plate between the every Filter pressing board.Operation principle: hydraulic oil promotes piston and pressure strip 16, and all filter plates are compressed, and pressure is controlled on the value that can guarantee the sealing of filter chamber periphery.Carry out charging filtration, water inlet washing respectively and go out filtrate by charging aperture 8, washing water inlet 9, filtrate (liquid 10, filtration finish or washing leaching cake after, adjust hydraulic fluid pressure to a high value (can effectively revert to principle) with elastic insert 4, filter cake is squeezed once more, reduce moisture percentage.Drawing-plate mechanism 11 and varicose mechanism 21 can finish block-by-block arm-tie and slag dumping work automatically.
