Abstract
The invention relates to a filtering device with a polytetrafluoroethylene membrane. A plurality of through holes are evenly formed in a corrugated pipe which is sleeved with a polytetrafluoroethylene microporous membrane hollow tube; one end of the corrugated pipe is sealed by the polytetrafluoroethylene microporous membrane tube, and an opening is formed in the other end of the corrugated pipe; a liquid extracting device is connected with the opening in a sealing manner; the thickness of a polytetrafluoroethylene microporous membrane layer is 0.3mm-0.9mm; micro air pores are evenly formed in the polytetrafluoroethylene microporous membrane; the diameters of the micro air pores are 0.5micron-3microns; the hole diameter of the corrugated pipe is 5mm-50mm; the diameters of the through holes in the corrugated pipe are 2mm-3mm. Through the filtering device, the corrugated pipe is placed in a filtering container; the liquid extracting device is arranged outside the filtering container; in the filtering container, a solution permeates into the corrugated pipe through the polytetrafluoroethylene microporous membrane layer and the through holes in the corrugated pipe, and then the liquid extracting device is used for extracting out a filtered pure solution in the corrugated pipe.
Description
Technical field:
The present invention relates to filter field, relate in particular a kind of filter with polytetrafluoroethylene film.
Background technology:
Now all need in a lot of fields to adopt filter that solution filter is clean, eliminate impurity, acid-base solution, bacterium and microorganism etc. in solution, existing filtration all can not thoroughly be eliminated, and needs a lot of process, complicated operation, thereby the use that also rear product is filtered in impact.
Microporous teflon membran is a kind of pliable and tough and whippy poromerics, porosity is high, even aperture distribution, there is the characteristic of filtering pervious function, it is outstanding that it has advantages of that many traditional filter membranes do not have, and its applicability is wide, is widely used in clothes, family, the fields such as medicine and chemical industry.
Summary of the invention:
The object of the invention is for the deficiencies in the prior art part, a kind of filter with polytetrafluoroethylene film is provided, it has filtration pervious function, can sterilization, sterilization, removal microorganism, be applied to filtration art.
Technology solution of the present invention is as follows:
With a filter for polytetrafluoroethylene film, it comprises bellows, is evenly equipped with multiple through holes on described bellows; Microporous teflon membran hollow tube of described bellows overcoat, and bellows one end is by microporous teflon membran duct occlusion, bellows other end opening; The salable pumping device that is connected with of described opening part.
As preferably, the thickness of described microporous teflon membran layer is 0.3～0.9mm, is evenly provided with micro-pore on microporous teflon membran, and micro-air vent aperture is 0.5～3um.
As preferably, described bellows aperture 5～50mm.
As preferably, the aperture of the through hole on described bellows is 2～3mm.
Beneficial effect of the present invention is:
Microporous teflon membran layer of the present invention can sterilization, sterilization, removal microorganism degraded automatically, when use, bellows is placed in filtering container, pumping device is positioned at filtering container outside, in filtering container, under pressure, solution can penetrate in bellows by the through hole on microporous teflon membran layer and bellows, and then pumping device is extracted the purified solution after bellows inner filtration out.The present invention is simple in structure, easy to use, and filtering accuracy is high.
Brief description of the drawings:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
Embodiment, is shown in accompanying drawing 1, a kind of filter with polytetrafluoroethylene film, and it comprises bellows 1, is evenly equipped with multiple through holes 2 on described bellows; Microporous teflon membran hollow tube 3 of described bellows overcoat, and bellows one end is by microporous teflon membran duct occlusion, bellows other end opening; The salable pumping device that is connected with of described opening part, pumping device is convenient to the purified solution after bellows inner filtration to extract out.
The thickness of described microporous teflon membran layer is 0.5mm, on microporous teflon membran, be evenly provided with micro-pore, micro-air vent aperture is 1um, microporous teflon membran, porosity is more than 80%, filter efficiency is more than 99%, the present invention can not hardened along with the time or embrittlement, the characteristic of good springiness and high-low temperature resistant-240 DEG C～260 DEG C, pH value 0-14, antifouling stifled, surface lubrication is outstanding, is applicable to the sewage disposal that various corrosivity is strong, salty buck distillation desalination, liquid-solid separation, gas-water separation, water-oil separating etc.
Described bellows aperture 40mm, multi-field use can, according to different conditions and the product that requires to be made into different size, be convenient in bellows aperture.
The aperture of the through hole on described bellows is 2mm, and through hole is convenient to entering of solution, also can ensure the balance adjustment of bellows external and internal pressure.
Above-described embodiment is the specific descriptions that the present invention is carried out; just the present invention is further described; can not be interpreted as limiting the scope of the present invention, those skilled in the art according to the content of foregoing invention make some nonessential improvement and adjust all fall into protection scope of the present invention within.
