Abstract
The utility model discloses a folded filter element with high filtration flux, and belongs to water treatment devices. The structure of the folded filter element is as follows: a layer of elastic supporting grids are stuck to each of the two lateral sides of a plate-type filtration film, then the filtration film is folded into an arc-shaped filtration film through a folding machine, and two ends of the filtration film are cohered together to form a cylindrical filtration film, an inner layer of stainless steel wire mesh and an outer layer of stainless steel wire mesh are used to reinforce and shape the filtration film, and finally the filter element fixes a sealing head, and the top end and the bottom end of the cylindrical filtration film are fixed in a sealing manner, thereby forming a cylindrical folded filter element. As the elasticity of the supporting grids enables the filtration film to be folded to an arc-shaped filtration film, the utility model avoids the dead corners generated in the prior folded shape, and greatly increases the filtration flux of the filtration film.
Description
Technical field:
The utility model relates to a kind of water treatment facilities, particularly has the foldable filter element of high filtration flux.
Background technology:
At present, the filter core that is used for water treatment both at home and abroad mostly is folding cylindrical filter cartridge, can be divided into polymeric membrane filter core and metal film filter core etc. according to the filter core material.Wherein the collapsed shape of foldable filter element has: pleat shape, W are corrugated, zigzag, corrugation shape etc., and common ground is all to have angular structures.The problem that the foldable filter element of these shapes in use exists is: filter core is when carrying out water treatment for a long time, and pollutant can accumulate in the angle folding place of filter membrane, makes the easy pollution of filter membrane and causes filtration flux to descend; These collapsed shape of filter membrane can make its effective filtration area reduce rapidly along with the pollution of film, and this is the another reason that causes filtration flux to descend; After the filter membrane pollution simultaneously, filter the dead angle owing to exist, the DeGrain that carries out backwash, filter membrane flux recovery rate reduces, and filter core shortening in service life causes cost of use to increase.
Summary of the invention:
The purpose of this utility model provides a kind of foldable filter element that is used for the high filtration flux of water treatment, to overcome the deficiency of existing water treatment foldable filter element.
The technical scheme that the utility model adopted is: adhere to one deck resiliency supported grid on the inside and outside two sides of filter membrane respectively, when filtering, normal-temperature water makes to support grid with glass cross, be higher than 30 ℃ then make to support grid if filter water temperature with nylon wire, to adhere to the filter membrane that supports grid afterwards is folded into cylindric, reinforce with the typing of columned internal layer and outer stainless (steel) wire again, at last in columned folding filter membrane top and bottom by filter core fixed seal head sealing and fixing.Wherein filter membrane can be macromolecular filter membrane or metal filtration film.
Because the upper and lower surface of filter core adheres to one deck resiliency supported grid respectively, makes filter membrane be folded into circular shape, the dead angle of having avoided prior folding shape to cause, thus having increased the effective filtration area of filter membrane, filtration flux has obtained large increase.
Description of drawings:
Fig. 1 is according to foldable filter element with high filtration flux structural representation provided by the utility model.
Fig. 2 is according to foldable filter element with high filtration flux cross-sectional structure schematic diagram provided by the utility model.
Among the figure: 1-filter core fixed seal head, 2-internal layer stainless (steel) wire, 3-filter membrane, the outer stainless (steel) wire of 4-.
The specific embodiment:
Further describe structure of the present utility model below in conjunction with accompanying drawing.
As shown in the figure, adhere to one deck resiliency supported grid respectively, when normal-temperature water is filtered, do to support grid, be higher than 30 ℃ then make to support grid with nylon wire if filter water temperature with glass cross in the inside and outside two sides of filter membrane 3.Outside the support grid, also there are internal layer stainless (steel) wire 2 and outer stainless (steel) wire 4 to make the typing back-up coats respectively.The manufacturing process of this filter core is: adhere to one deck resiliency supported grid respectively in the inside and outside two sides of filter membrane 3, with folding machine it is folded into circular-arc folding filter membrane 3, to fold again the filter membrane two ends be bonded together form cylindric, to fold filter membrane 3 with internal layer stainless (steel) wire 2 and outer stainless (steel) wire 4 and add fixed, with filter core fixed seal head 1 columned folding filter membrane 3 tops and bottom end seal are fixed at last, made the foldable filter element shown in accompanying drawing 1 or 2.The foldable filter element of this filter core and same material compares, and filtration flux is greatly improved.
Claims (3)
1. the foldable filter element of a high filtration flux, comprise filter membrane, internal layer and outer stainless (steel) wire, filter core fixed seal head, it is characterized in that on the inside and outside two sides of filter membrane, adhering to respectively one deck resiliency supported grid, afterwards filter membrane is folded into cylindric, reinforce with the typing of columned internal layer and outer stainless (steel) wire again, at last in columned folding filter membrane top and bottom by filter core fixed seal head sealing and fixing.
