Abstract
The utility model relates to a plane board micro-hole hollow filtration board applicable to the purification and filtration of low-viscosity fluid, which comprises a upper flirtation board, a lower filtration board, a framework composed of a long and a short reinforcement bar in between the upper and lower filtration boards, a clean fluid cavity enclosed by the upper and lower filtration boards, a framework and an external brim and a clean fluid outlet communicated with the clean fluid cavity. The upper and lower filtration boards have dual-layer structure; the framework in between the upper and lower filtration boards has integral structure formed in one piece; the wrapping layer at the end surface of the external brim of upper and lower filtration boards is provided with integral structure formed in one piece. Compared with existing filtration boards, the utility model can adopt the processing technique of forming in two times; the clean fluid cavity is formed with rigid mould; the internal surface of the formed clean fluid cavity can form precise filtration layer; a plurality pieces of framework can be arranged freely to connect the two filtration boards, so as to enhance the strength of the plane filtration film in enduring the internal and external pressure and ensure that no residual materials are left in the clean fluid cavity. Besides, the dual-layer upper and lower filtration boards, with excellent integration, can improve the service life of the utility model.
Description
Technical field:
The utility model relates to a kind of various low-viscosity (mobile) liquids, the filter plate that gas cleaning filters or solid-liquid (gas-solid) separates, hollow filter plate of specifically a kind of flat plate porous film of being applicable to.
Background technology:
The known filter plate such as the patent No. are 00205767.0 the hollow filter plate of microporous barrier, adopt plastic welding to connect between the upper and lower filter plate periphery of its clean sap cavity part, filter plate outer rim end face does not have edging layer, therefore is subjected to the effect of the inside and outside pressure in chamber in use, easy to crack, the distortion of weld seam part; Also having a kind of filter plate such as the patent No. is 96215536.5 liquid filtering sheet, though the outer rim end face has the edging layer that is combined into one with upper and lower filter disc, can overcome the former described defective, but when it makes clean sap cavity, the material that must adopt fusible material (as paraffin wax) or water-soluble material (as yellow mud, gypsum) or dissolve in some chemical solvent is made inner bag, make inner bag dissolving or the clean sap cavity of fusing back formation through high temperature sintering, the clean sap cavity that this mode forms exists inner surface loosely to fall slag, many quality problems such as residue is arranged.
Summary of the invention:
Goal of the invention of the present utility model is intended to solve defective and the problem that the above-mentioned background technology exists, and provide a kind of filter membrane globality strong, bear big, the clean sap cavity surface smoothness height of external and internal pressure, can improve the hollow filter plate of flat plate porous film in filtering accuracy and service life.
The technical scheme that realizes the foregoing invention purpose is: the hollow filter plate of this flat plate porous film comprises: upper and lower filter plate, place the skeleton of forming by long muscle and short muscle between this upper and lower filter plate, the clean sap cavity that constitutes by this upper and lower filter plate and skeleton and outer rim shutoff, the clean liquid outlet that is communicated with described clean sap cavity, this upper and lower filter plate is double-decker, and upper and lower filter plate of internal layer and skeleton between the two are the one-time formed overall structure of mould; Outer upper and lower filter plate is one-time formed overall structure with the edging layer of the upper and lower filter plate outer rim of this internal layer of sealing end face.
The hollow filter plate of flat plate porous film according to this case realization, compare with known filter plate, can adopt contour machining procedure twice, the rigidity mould is adopted in the moulding of clean sap cavity, the clean sap cavity inner surface of making thus can form the secondary filter layer, and the skeleton (muscle) that multiple tracks connects the two sides filter plate can be set arbitrarily, improving the intensity that dull and stereotyped filter membrane bears external and internal pressure, and clean sap cavity does not have residue; Double-deck upper and lower filter plate constitutes an integral body by the edging layer of its outer rim end face, and therefore the globality of dull and stereotyped filter membrane is strong, can improve service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A section structure schematic diagram among Fig. 1.
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.
The hollow filter plate of the flat plate porous film that present embodiment provides is by forming with lower member: upper and lower filter plate 1, place the skeleton of forming by long muscle 2 and short muscle 3 between this upper and lower filter plate 1, outer rim shutoff 4, by the clean sap cavity 5 that this upper and lower filter plate 1 and skeleton and outer rim shutoff 4 constitute, the clean liquid outlet 6 that is communicated with described clean sap cavity 5.
This upper and lower filter plate 1 is double-decker, and upper and lower filter plate 7 of internal layer and skeleton between the two are the one-time formed overall structure of mould; Outer upper and lower filter plate 8 is one-time formed overall structure with the edging layer 9 of the upper and lower filter plate 7 outer rim end faces of this internal layer of sealing.
Claims (2)
1, the hollow filter plate of a kind of flat plate porous film, comprise: upper and lower filter plate, place the skeleton of forming by long muscle and short muscle between this upper and lower filter plate, the clean sap cavity that constitutes by this upper and lower filter plate and skeleton and outer rim shutoff, the clean liquid outlet that is communicated with described clean sap cavity, it is characterized in that this upper and lower filter plate is double-decker, upper and lower filter plate of internal layer and skeleton between the two are the one-time formed overall structure of mould; Outer upper and lower filter plate is one-time formed overall structure with the edging layer of the upper and lower filter plate outer rim of this internal layer of sealing end face.
2, the hollow filter plate of flat plate porous film according to claim 1 is characterized in that described long muscle is radial arrangement by clean liquid outlet to the filter plate periphery, arranges some short muscle between per two long muscle.
