Description

A kind of novel nano filter cloth
Technical field
The invention belongs to technical field of sewage purification more particularly to a kind of novel nano filter clothes.
Background technique
Filter cloth is the filter medium that industrially purposes is most wide.Filter cloth is divided into weaving filter cloth and two kinds of non-thermoplastic filter cloth.Mesh Before, filter cloth of largely weaving on domestic market is made of multifilament or short fibre, and tissue is mostly the single layers groups such as plain weave, twill, satin weave It knits, in use, suspension is contacted with filter cloth, and under the effect of the pressure, the molecule less than filter cloth aperture passes through filter Cloth, the particle greater than filter cloth aperture stay in filter cloth surface layer, form filter cake, constantly shut off particle, to realize separation of solid and liquid.
China Patent Publication No. is 207047463 U of CN, entitled a kind of monofilament filter cloth of innovation and creation, using polypropylene fibre The filter cloth of monofilament integrally becomes frivolous, mitigates the heavy feeling of filter cloth, effectively improves the drainability of filter cloth, filters out with certain viscosity Material, extend the service life of filter cloth, the high-temperaure coating wrapped up outside monofilament makes filter cloth, and the service life is longer, reduce at This.But there is contaminant filters to be not thorough for existing filter device, the service life is short, is easily damaged, and filter effect is undesirable, influences to make The problem of with experience.
Therefore, a kind of novel nano filter cloth is invented to be very necessary.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of novel nano filter clothes, are deposited with solving existing filter device It is not thorough in contaminant filter, the service life is short, is easily damaged, and filter effect is undesirable, the problem of influencing usage experience.It is a kind of novel Nanometer filter cloth, including particle film layer, coarse filtration layer, reverse osmosis permeable layers collect water layer, water conservancy diversion protrusion, edge sealing and protective layer, wherein：Slightly Filter layer is bonded in the upper surface of particle film layer, and the lower surface of particle film layer is bonded with reverse osmosis permeable layers；The collection water layer bonding In the lower section of reverse osmosis permeable layers, and the lower surface for collecting water layer bonds several rubber bumps；Edge sealing sewing is in whole filter layer Periphery, and be sewed with above edge sealing and protective layer.
The particle film layer uses Nano granules of stannic oxide film, and particle film layer uses three layers, is conducive to the greatest extent The impurity in water is filtered out, prevents large-scale impurity from blocking whole filter cloth.
The reverse osmosis permeable layers are deposited between reverse osmosis permeable layers and other structures using the artificial semi-permeable membrane between 0.5~10nm In gap, in the case where being conducive to above filter cloth hydraulic pressure and be greater than lower section hydraulic pressure, using pressure difference as power, by pure water out of filter membrane It squeezes out.
The collection water layer or water conservancy diversion protrusion use super absorbent resin thin layer or flexible rubber particle, and collect water layer and reverse osmosis There are gap between permeable layers, be conducive to for the clean water stream of generation being collected, and flow out water flow boundling by water conservancy diversion protrusion, Prevent excessive water impact from damaging filter cloth.
The protective layer uses ultra-thin rubber layer, and protective layer is provided with several permeable holes, is conducive to protect filter cloth Core filter structure prevent by hard object scratch damage.
Compared with prior art, the present invention has the advantages that：
1. the setting of particle film layer of the present invention is conducive to filter out the impurity in water to the greatest extent, prevents large-scale impurity Block whole filter cloth.
2. the setting of reverse osmosis permeable layers of the present invention, in the case where being conducive to that hydraulic pressure is greater than lower section hydraulic pressure above filter cloth, with pressure Power difference is power, and pure water is squeezed out out of filter membrane.
3. the setting of present invention collection water layer or water conservancy diversion protrusion, is conducive to for the clean water stream of generation being collected, and pass through Water conservancy diversion protrusion flows out water flow boundling, prevents excessive water impact from damaging filter cloth.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure：
1- particle film layer, 2- coarse filtration layer, 3- reverse osmosis permeable layers, 4- collection water layer, 5- water conservancy diversion protrusion, 6- edge sealing, 7- protective layer.
Specific embodiment
The present invention is described further below in conjunction with attached drawing：
Embodiment：
As shown in Fig. 1
The present invention provides a kind of novel nano filter cloth, including particle film layer 1, coarse filtration layer 2, and reverse osmosis permeable layers 3 collect water layer 4, Water conservancy diversion protrusion 5, edge sealing 6 and protective layer 7, wherein：Coarse filtration layer 2 is bonded in the upper surface of particle film layer 1, and particle film layer 1 Lower surface is bonded with reverse osmosis permeable layers 3；The collection water layer 4 is bonded in the lower section of reverse osmosis permeable layers 3, and collects the lower surface bonding of water layer 4 Several rubber bumps；The sewing of edge sealing 6 is on the periphery of whole filter layer, and the top of edge sealing 6 is sewed with and protective layer 7.
The particle film layer 1 uses Nano granules of stannic oxide film, and particle film layer 1 uses three layers, is conducive to utmostly The impurity filtered out in water, prevent large-scale impurity from blocking whole filter cloth.
The reverse osmosis permeable layers 3 use the artificial semi-permeable membrane between 0.5~10nm, and between reverse osmosis permeable layers 3 and other structures There are gap, in the case where being conducive to above filter cloth hydraulic pressure and be greater than lower section hydraulic pressure, using pressure difference as power, by pure water from filter membrane Interior extrusion.
The collection water layer 4 or water conservancy diversion protrusion 5 use super absorbent resin thin layer or flexible rubber particle, and collect water layer 4 with There are gap between reverse osmosis permeable layers 3, be conducive to for the clean water stream of generation being collected, and pass through water conservancy diversion protrusion 5 for water flow collection Line goes out, and prevents excessive water impact from damaging filter cloth.
The protective layer 7 uses ultra-thin rubber layer, and 7 surface of protective layer is provided with several permeable holes, is conducive to protection filter The core filter structure of cloth is prevented from being scratched by hard object and be damaged.
Working principle
In present invention, it is desirable to the water of filtering enters filter plant by the permeable hole on 7 surface of protective layer, pass through particle first Film layer 1 filters out the impurity in water to the greatest extent, prevents large-scale impurity from blocking whole filter cloth, subsequently into reverse osmosis permeable layers 3, In the case where being conducive to above filter cloth hydraulic pressure and be greater than lower section hydraulic pressure, using pressure difference as power, pure water is squeezed out out of filter membrane, most The clean water stream of generation is collected by collection water layer 4 afterwards, and and water flow boundling is flowed out by water conservancy diversion protrusion 5, prevented Big water impact damages filter cloth, completes filtering.
Using technical solution of the present invention or those skilled in the art under the inspiration of technical solution of the present invention, if Similar technical solution is counted out, and reaches above-mentioned technical effect, is to fall into protection scope of the present invention.
