Description

The high strength membrane filter plate

Technical field

The utility model relates to a kind of high strength membrane filter plate that can make diaphragm seal faying face and the highly reliable sealing of central layer sealed faying face, belongs to membrane filter plate and makes the field.

Background technology

All CN101091845A of the applicant, title " high efficiency long-life multifunctional membrane and filter plate and forming method ", it comprises filter sheet core and barrier film, is positioned at the directly injection mo(u)lding on filter sheet core of barrier film on the filter sheet core.Barrier film is directly injection-moulded on the filter sheet core, avoid the secondary smear metal, chamfering, technologies such as deburring, the saving of labor, save time, the efficient height, and quality of fit of the two and sealing reliability have reached 100% of initiative, and realized ultra-thinization of membrane thicknesses, but elastification, when particularly eardrum filters squeezing, but the barrier film of ultra-thin elastification can make eardrum touch the filtrate (especially filtrate seldom time) at each position in the filter plate effectively, the barrier film and the bonding difficult problem of filter sheet core injection moulding that constitute the eardrum crushing chamber have fundamentally been solved, the more important thing is, this structure has fundamentally realized the precisionization in eardrum crushing chamber space, effective eardrum, energy efficient not only, and eardrum is effective, the efficient height, and the life-span is long.

Summary of the invention

Purpose of design: on the basis of background technology, design a kind of barrier film that makes under the situation of bearing the high pressure eardrum, guarantee highly reliable sealing between diaphragm seal faying face and the central layer sealing surface and the high strength membrane filter plate that can not torn or tear or leak by the high-pressure fluid eardrum.

Design: in order to realize above-mentioned purpose of design.1, the design of core metal sheet in the central layer is one of feature of the present utility model.The purpose of doing like this is: the setting of core metal sheet, as in central layer, being equipped with reinforcement, can fundamentally improve resistance to compression, the bending strength of central layer so especially, and improve the whole service life of central layer.2, the sealed faying face of central layer has 1 or 2 or a plurality of nail groove or nail hole, and the design of adopting ailhead to fix or adopt the nail bar to be connected between the barrier film that is positioned at the central layer two sides and barrier film is two of a feature of the present utility model.The purpose of doing like this is: be positioned on the sealed faying face of central layer two sides and diaphragm seal coupling and have at interval a plurality of nail grooves or nail hole, this nail groove is equipped be connected with barrier film ailhead or nail hole and is built-in with the nail bar, the both ends of the surface of nail bar are whole syndeton with the diaphragm seal face that is positioned at the central layer two sides respectively, make and be in nail bar that heat melts state in the injection moulding process and be in heat and melt the diaphragm seal composition surface fusion of state and be connected, and in the process that its cooling is shunk, owing to be subjected to the influence of the coefficient of thermal expansion and contraction of material own, the barrier film that progressively will be positioned at the central layer two sides is pinned on the sealing surface of central layer tightly, thereby greatly improved the sealing intensity between diaphragm seal face and central layer sealing surface, greatly improved the effect of barrier film high pressure eardrum; And the ailhead that is positioned at the barrier film back side is in central layer injection mo(u)lding during as template, when barrier film is injection-moulded on the central layer, molten plastic injects in the nail groove or nail hole of central layer sealed faying face, make barrier film in injection mo(u)lding, form ailhead and hammer into the effect of central layer, thereby barrier film firmly is fixed on the central layer with central layer.

Technical scheme: high strength membrane filter plate, the sealed faying face of two barrier films is complementary with the sealed faying face of central layer respectively, the sealed faying face of described barrier film is provided with 1 or 2 or a plurality of ailhead or nail bar, and the sealed faying face that is equipped with core metal sheet and central layer in the described central layer is provided with nail slotted eye that 1 or 2 or a plurality of and ailhead or nail bar be complementary and is provided with 1 or 2 or a plurality of ailhead or follows closely bar with the sealed faying face of barrier film and is complementary.

The utility model is compared with background technology, and the one, thus greatly improved sealing intensity between diaphragm seal face and central layer sealing surface, greatly improved the effect of barrier film high pressure eardrum; The 2nd, greatly improved filtration, squeezing effect, not only greatly improve the utilization rate of resource, and reduced production cost and energy resource consumption.

Description of drawings

Fig. 1 is the structural representation of first kind of embodiment of high strength membrane filter plate.

The specific embodiment

Embodiment 1: with reference to accompanying drawing 1.High strength membrane filter plate, the sealed faying face of two barrier films are complementary with the sealed faying face of central layer respectively, and the processing and fabricating of barrier film 1 and central layer 2 is a prior art, is not described herein at this.The sealed faying face of described 1 barrier film is provided with 1 or 2 or a plurality of ailhead 3 or nail bar 4, the sealed faying face that is equipped with core metal sheet 7 and central layer 2 in the described central layer 2 is provided with nail groove 5 that 1 or 2 or a plurality of and ailhead 3 or nail bar 4 are complementary or 6 holes and is provided with 1 or 2 or a plurality of ailhead 3 or nail bar 4 with the sealed faying face of barrier film 1 and is complementary, hole on central layer 2 sealing surfaces and the hole in the core metal sheet 7 connect, that is to say, when adopting central layer 2 as the module of barrier film 1, central layer 2 is put into mould, when molten plastic was directly injection-moulded in two of central layer 2, molten plastic flowed into 2 or a plurality of perforation nail hole 3 and makes barrier film 1 sealed faying face on 2 two sealed faying faces of central layer be linked to be integral body and shrink gradually in the process of plastic cool, barrier film 1 sealing surface that will be positioned at central layer 2 two sides sealed junction firmly is combined on the sealed faying face of central layer 2.The diaphragm plane periphery is provided with by the inclined-plane or by the elastic ring shape potted line that convex is formed, and can guarantee diaphragm filter press sealing property when compressing use, does not have fluid to leak in the time of can not making the eardrum squeezing.Outer end around the barrier film is the inclined-plane and combines with central layer skewed slot all around, can prevent when diaphragm plane is badly damaged, when squeezing eardrum fluid leaks, the inclined-plane of outermost end and central layer can compress sealing automatically under the effect of fluid pressure, the pressure that leaks is big more, thrust is also big more, and is tight more from movable sealing, thereby reliably prevented the generation that leaks once more.

What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; it is text description to the utility model mentality of designing; rather than to restriction of the present utility model; any combination, omission or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
