Fig. 1 is a kind of structural representation of diaphragm filter board of filter press; Fig. 2 is the A-A cutaway view in Fig. 1; As Fig. 1 and Fig. 2Shown in, the filter plate of filter press of the present utility model, comprises sheet frame 1, sheet frame 1 both sides are provided with the barrier film 2 of being made up of elastomeric material,Between the barrier film 2 of sheet frame 1 and both sides, sealing into one can be filled with or the medium cavity volume 14 of discharge pressure medium; Fig. 3 is barrier film 2Structural representation; Fig. 4 is the B-B cutaway view in Fig. 3; As shown in Figure 3 and Figure 4, barrier film 2 comprises for being situated between with pressureThe medial surface 21 of matter contact, the lateral surface 22 for contacting with sewage, barrier film 2 middle parts are provided with mud hole 225; As Fig. 1 and TuShown in 2, between the mud hole 225 of the barrier film 2 of sheet frame 1 both sides, be provided with mud passage 25, sheet frame 1 is provided with exhalant canal 15,The lateral surface 22 of 225 peripheries, mud hole is provided with press filtration region 226 (seeing Fig. 3), and press filtration region 226 is laid with multiple projections221 (seeing Fig. 3). Projection 221 can be the arbitrary shape that can form in press filtration region 226 multiple raised zones, for the ease ofManufacture processing, projection 221 can be arranged to the column of regular geometric shapes, as cylinder, rectangular column etc., protruding 221 topsFor plane; In order to make the mud in mud cavity volume be subject to pushing relatively uniformly, can be by the projection in press filtration region 226 221Distribute equably. Connect together when multiple filter plates are folded, on barrier film 2 surfaces of filter plate both sides, be coated with filter cloth (not shown),Between the relative barrier film 2 of two adjacent filter plates, form mud cavity volume (not shown); Hold to mud by mud passage 25In chamber, be filled with mud, then mud pass into pressure medium between filter cloth in medium cavity volume 14, under the effect of pressure medium,The outwards support and heaving of the pressurized medium of barrier film 2, pushes and makes sludge dewatering the mud in mud cavity volume. Due at filter plateThe surface of both sides is provided with multiple protruding 221, between projection 221, has formed the drainage gap 222 that is beneficial to draining, from mud, squeezesThe sewage extruding can be discharged by drainage gap 222; Projection 221 is less with the contact area of mud, in medium cavity volume 14Pass in the situation of medium of uniform pressure, surface has that projection 221 filter plate compares can be to mud with the filter plate of surface smoothingProduce larger pressure, make the moisture in mud discharge more abundant.
As depicted in figs. 1 and 2, as a kind of embodiment of filter press filter board of the present utility model, filter plate props up in the middle of having oneSupport part 17, the central authorities of intermediate supports portion 17 have a duct (not indicating in figure), close on barrier film 2 medial surfaces 21 of filter plateThe medial surface 21 in outer edge place, mud hole 225 is equipped with the sealing ring 24 for coordinating with the sheet frame 1 of filter plate, apopore 23Sealing ring 24 outsides that are positioned at close outer edge place on barrier film 2 medial surfaces 21, mud hole 225 is positioned on barrier film 2 medial surfaces 21The inner side of the sealing ring 24 at close outer edge place, the duct place of the two sides of sheet frame 1 and intermediate supports portion 17 is provided with and sealing ring24 corresponding seal grooves (not indicating in figure), the barrier film 2 of filter plate both sides is embedded in seal groove and the intermediate supports portion of sheet frame 1 sideIn the seal groove in 17 ducts place, between the duct of intermediate supports portion 17 and mud hole 225 inwalls of barrier film 2, be also provided with a corePipe 16, the external cylindrical surface of core pipe 16 and mud hole 225 wall tight fits, by mud hole 225 walls and the intermediate supports portion of barrier film 217 duct compresses so that positiver sealing between the two, and the inner cylinder face of core pipe 16 forms described mud passage 25. Sheet frame 1Between the barrier film 2 of intermediate supports portion 17 and filter plate both sides, form left and right two medium cavity volumes 14, on the sheet frame 1 of filter plate, establishThere are medium import 11 and media outlet 12; Between the medium cavity volume 14 on medium import 11 and left and right both sides, respectively pass through two companiesThrough hole 13 be communicated with (in Fig. 2, due to the selection of split surface, in Fig. 2 left side medium cavity volume 14 and medium import 11 betweenIntercommunicating pore 13 can not show), intercommunicating pore 13 is arranged on sheet frame 1 inside; And between medium import 11, medium cavity volume 14Mode of communicating similar, between the medium cavity volume 14 on media outlet 12 and left and right both sides, be also respectively communicated with by two intercommunicating pores 13.In the embodiment of above-mentioned filter press filter board, intermediate supports portion 17 is set on filter plate is mainly for can be to 2, the barrier film of filter plateTo certain supporting role, prevent that the barrier film 2 of filter plate is to medium cavity volume 14 inner side depressed deformations; But intermediate supports portion 17 is notBe essential structure, can also support the barrier film 2 of filter plate in case it is to medium cavity volume 14 inner side depressed deformations by other mode.In the above-described embodiment, between the two sides of intermediate supports portion 17 and the barrier film 2 of filter plate both sides, forming respectively a medium holdsChamber 14, also can get through intermediate supports portion 17, the medium cavity volume 14 of intermediate supports portion 17 both sides is connected and is merged into oneThe medium cavity volume 14 of individual entirety.
As shown in figures 1 and 3, be provided with the apopore 23 running through on barrier film 2, apopore 23 can be arranged at press filtration region226 periphery, press filtration region 226 multiple protruding 221 between form drainage gap 222, drainage gap 222 is interconnected alsoAnd between apopore 23, be communicated with, between the exhalant canal 15 on apopore 23 and sheet frame 1, be connected by communicating passage 26,Communicating passage 26 is located at sheet frame 1 inside. For the ease of going out being communicated with between water space and apopore 23 on barrier film 2, everyFilm 2 is provided with drainage trap 223, between drainage gap 222 and apopore 23, is communicated with by drainage trap 223. Using filter pressWhen mud is carried out to extrusion dehydration, multiple filter plates are folded to connect together, and between the relative barrier film 2 of two adjacent filter plates, forms mudCavity volume, in order to prevent that the sewage in mud from oozing out from the binding face of two adjacent filter plates, can be on the lateral surface of barrier film 2 22 limitsBe provided with a circle sealing lip 224 along place, in the time that multiple filter plates are folded even, the sealing lip 224 of relative barrier film 2 on adjacent two filter platesBonded to each other and compress, sewage can not ooze out from the binding face of two adjacent filter plates.
The barrier film 2 of filter plate both sides can be made up of rubber, in order to pass into pressure medium in the medium cavity volume 14 of filter plateUtilize pressure that the moisture in mud cavity volume is extruded, can also be to passing into thermal medium in the medium cavity volume 14 of filter plate with to mud cavity volumeIn mud heat, make the moisture vaporization of mud in mud cavity volume and overflow, can adopt heat conductive rubber to make filter plate both sidesBarrier film 2. Because the press filtration region 226 in barrier film 2 outsides is laid with multiple protrudingly 221, increase area of dissipation, medium cavity volumeThe heat of the thermal medium passing in 14 can pass to the mud in mud cavity volume quickly, makes the moisture in mud can be quicklyVaporize and overflow.
The above is only preferred embodiment of the present utility model, it should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model know-why, can also make some improvement and replacement, these improvement and replacingChange and also should be considered as protection domain of the present utility model.
