Description
Technical field
This utility model relates to a kind of filter element, refers more particularly to a kind of double-component with high porosity and rigid structure
Takeup type filter element.
Background technology
Existing melt-blown filter membrane typically uses one-component fiber to make, when hot melt molding, owing to one-component fiber easily produces
Raw high temperature melt, easily causes the phenomenons such as torsion of fibers, high network density and hole subside so that filter membrane mistake in grid contact position
The concordance of filter precision is poor, reliability is low and intensity is not enough, it is impossible to meets and uses requirement.
Utility model content
This utility model mainly solves existing melt-blown filter membrane and can produce node when fiber hot melt merges because of rigidity not and melt
The technical problem that change, torsion of fibers and hole subside；Provide a kind of double-component winding with high porosity and rigid structure
Formula filter element.
In order to solve the technical problem of above-mentioned existence, this utility model mainly uses following technical proposals:
A kind of double-component takeup type filter element of the present utility model, including the filter membrane in tubular structure, the material of described filter membrane
For double-component hot-melt prepreg machine material, filter membrane hot melt winding forms multiple filtration structure, and the inner chamber of filter membrane forms liquid and flows out
Passage, filter membrane use bicomponent fibers hot melt winding formed multilayered cylindrical structure, bicomponent fibers when hot melt is shaped, rigidity and
The sandwich layer tissue that fusing point is higher can maintain structural strength and the hole precision of fiber, will not occur node fusing, torsion of fibers and
The phenomenon that hole subsides, it is ensured that the rigidity of filter membrane, high porosity and filtering accuracy, the relatively low cortical tissue of soft and fusing point is then
Can partial melting and mutually bond, make filter membrane form entirety and have the fine grid blocks of high degrees of fusion, it is ensured that filter membrane structure steady
Qualitative, concordance and rigidity, effectively extend the service life of filter element.
As preferably, described double-component hot-melt prepreg machine is ES fiber, and cortical tissue is PE fiber, and sandwich layer is organized as PP
Fiber, as the cortical tissue in double-component skin-core structure composite fibre, PE fiber has the feature that fusing point is low, flexibility is good,
After the hot melt through special producing technique, a part of PE fibers melt and mutually bond, make bicomponent fibers connect fully, and
As sandwich layer tissue, PP fiber then has the feature that fusing point is high, intensity is good and percent thermal shrinkage is little, through special producing technique
After hot melt, still retain its stable fiber condition so that the structural strength of filter membrane is highly improved.
As preferably, described membrane filtration precision is 1 μm～150 μm, fully meets the filter element requirement of different filtering accuracy.
The beneficial effects of the utility model are: filter membrane uses bicomponent fibers hot melt winding to form multiple structure, double-component
Fiber is when hot melt is shaped, and the sandwich layer tissue of rigidity can maintain structural strength and the hole precision of fiber, and node will not be occurred to melt
The phenomenon that change, torsion of fibers and hole subside, it is ensured that the rigidity of filter membrane, high porosity and filtering accuracy, cortical tissue then may be used
Partial melting and mutually bond, make filter membrane form entirety and have the fine grid blocks of high degrees of fusion, it is ensured that stablizing of filter membrane structure
Property, concordance and rigidity, effectively extend the service life of filter element.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the schematic top plan view of Fig. 1 structure.
1. filter membrane in figure, 2. liquid outflow channel.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment: a kind of double-component takeup type filter element of the present embodiment, as depicted in figs. 1 and 2, including in tubular structure
Filter membrane, filter membrane material is double-component hot-melt prepreg machine, and filter membrane forms multiple filtration structure, the inner chamber of filter membrane by hot melt winding
Forming liquid outflow channel, double-component hot-melt prepreg machine is ES fiber, and membrane filtration precision is 50 μm.
During use, directly being installed on the filter by filter element, now, liquid flows to filter membrane 1 from outside to inside, passes through double-component
Flow into the liquid outflow channel 2 of filter membrane after the multiple filtration of filter membrane, finally flow out filter element, complete the filtration of liquid, due to filter element
Bicomponent fibers multiple structure so that filter membrane will not occur what node fusing, torsion of fibers and hole subsided to show when hot melt
As, make filter membrane have the fine grid blocks of high degrees of fusion, the reliability of filter course and concordance are preferable, can conveniently remove in liquid relatively
Big particle and agglomerate, will not peel off again the less acceptable or particle of needs simultaneously, be greatly prolonged the use longevity of filter element
Life.
In description of the present utility model, technical term " on ", D score, "front", "rear", "left", "right" " interior ", " outward " etc.
Represent that direction or position relationship are based on direction shown in the drawings or position relationship, be for only for ease of description and understand this practicality
Novel technical scheme, described above not work this utility model limits, and this utility model is also not limited to described above
Citing, change that those skilled in the art are made in essential scope of the present utility model, retrofit, increase
Or replace, it is regarded as protection domain of the present utility model.
