Abstract
PP cotton filter element is laminated in takeup type, including one or more layers laminar PP cotton layer is bonded to each other, and coaxial gradual layer-by-layer annular winding forms circular cylindrical filter element body, is formed with centre bore at the center of circular cylindrical filter element body.In processing, it first passes through melt-blown and obtains laminar PP cotton layer, the PP cotton layer can be single layer structure, it is also possible to multiple-layer stacked structure, then the coaxial gradual layer-by-layer annular of PP cotton layer is wound, and its center is hollow, the filtering accuracy of circular cylindrical filter element body internal layer after winding in this way is high, outer layer has certain stretching in winding, filtering accuracy after stretching is lower, inside and outside filtering accuracy is different, outer layer carries out thick effect filtering in this way, it is not easy to plug, internal layer carries out high efficiency filter, filter effect is good, just entire PP cotton filter element is replaced to avoid the occurrence of outer layer blocking, long service life, reduce replacement frequency and replacement cost.
Description
Technical field
The utility model relates to PP cotton filter elements, and PP cotton filter element is laminated more particularly to takeup type.
Background technique
Tubulose filter core, the filtering essence of surface layer and internal layer is made generally by melt-blown is directly surrounded in existing PP cotton filter element
Degree is the same, and filtering accuracy is single, and in use for some time, surface layer blocking just causes whole branch filter core to be scrapped, needs PP cotton filter element
Entire replacement, filter core inside serious waste, frequently, filter element replacing cost is excessively high for the short replacement of filter core service life.
Summary of the invention
The purpose of this utility model is to overcome prior art there are the shortcomings that, it is simple to provide a kind of structure, manufacturer
Just, PP cotton filter element is laminated in long service life, the takeup type for reducing replacement frequency and replacement cost.
The technical solution of the utility model takeup type stacking PP cotton filter element is: including one or more layers laminar PP
Cotton layer is bonded to each other, and coaxial gradual layer-by-layer annular winding forms circular cylindrical filter element body, in circular cylindrical filter element body
Center be formed with centre bore.
The utility model discloses a kind of takeup types, and PP cotton filter element is laminated, and in processing, first passes through melt-blown and obtains flake
PP cotton layer, which can be single layer structure, is also possible to multiple-layer stacked structure, then by PP cotton layer it is coaxial it is gradual by
Layer annular winding, and its center is hollow, the filtering accuracy height of the circular cylindrical filter element body internal layer after winding in this way, outer layer exists
Certain stretching is had when winding, the filtering accuracy after stretching is lower, and inside and outside filtering accuracy is different, and such outer layer progress was slightly imitated
Filter, is not easy to plug, and internal layer carries out high efficiency filter, and filter effect is good, just filters entire PP cotton to avoid the occurrence of outer layer blocking
Core replacement, long service life reduce replacement frequency and replacement cost.
PP cotton filter element is laminated in the utility model takeup type, and the one or more layers laminar PP cotton layer is plane
Circular cylindrical filter element body is formed after rolled.The one or more layers laminar PP cotton layer is plane through organ type
Winding forms circular cylindrical foldable filter element ontology after folding.It after PP cotton layer is passed through organ type foldable, then is wound, can increase
Its filter area, to can be further improved filter effect.
Detailed description of the invention
Fig. 1 is the schematic top plan view that plane PP cotton layer is wound as circular cylindrical filter element body；
Fig. 2 is the schematic top plan view that organ type foldable PP cotton layer is wound as circular cylindrical foldable filter element ontology.
Specific embodiment
The utility model relates to a kind of takeup type be laminated PP cotton filter element, as shown in Fig. 1-Fig. 2, including one layer or one layer with
Upper laminar PP cotton layer 1 is bonded to each other, and coaxial gradual layer-by-layer annular winding forms circular cylindrical filter element body, in annular
The center of column filter element body is formed with centre bore 2.In processing, first passes through melt-blown and obtain laminar PP cotton layer 1, the PP cotton layer
1 can be single layer structure, be also possible to multiple-layer stacked structure, then wind the coaxial gradual layer-by-layer annular of PP cotton layer 1, and its
Center be it is hollow, the filtering accuracy of the circular cylindrical filter element body internal layer after winding in this way is high, and outer layer has centainly in winding
Stretching, the filtering accuracy after stretching is lower, and inside and outside filtering accuracy is different, and such outer layer carries out thick effect filtering, is not easy to plug, interior
Layer carries out high efficiency filter, and filter effect is good, just replaces entire PP cotton filter element to avoid the occurrence of outer layer blocking, service life
It is long, reduce replacement frequency and replacement cost.The one or more layers laminar PP cotton layer 1 is the rolled rear shape of plane
Circularize column filter element body 3.The one or more layers laminar PP cotton layer 1 is rolled up after organ type foldable for plane
Around formation circular cylindrical foldable filter element ontology 4.It after PP cotton layer 1 is passed through organ type foldable, then is wound, its filtering can be increased
Area, to can be further improved filter effect.
