Abstract
The present invention provides a kind of detachable melt-blown filter structure, the problem of can avoiding causing internal layer filter core utilization benefit too low after the too early dirt of outer layer filter core is stifled, it is characterised in that：The layer of meltblown fibers that in sleeve and adjacent layer is also adapted is placed in including filter core sleeve, with what sleeve was adapted, the filter core sleeve includes covering on sleeve body and sleeve, the layer of meltblown fibers has 25 layers and successively density increase, aperture also successively reduce from outside to inside, the upper and lower ends of every layer of layer of meltblown fibers are all annular hard stainless steel frame, it is connected between two annular hard stainless steel frames of the upper and lower ends with stainless steel stent, is allowed to easily install to strengthen the rigidity of the layer of meltblown fibers, reduce the coefficient of friction between adjacent layer.
Description
Technical field
The present invention relates to a kind of melt-blown filter structure applied to water purifier.
Background technology
Melt-blown filter is to use nonpoisonous and tasteless polypropylene particles, through heating melting, spinneret, traction, receive shape and
Manufactured tubulose filter core.If raw material based on polypropylene, just turns into PP melt-blown filters.Melt-blown filter in water purification high-volume
Use, there is good chemical compatibility, suitable for the filtering of strong acid, highly basic and organic solvent, its pollutant carrying capacity is strong, uses the longevity
Life length, cost are low.
A kind of melt-blown filter that water purifier uses at present is the meltblown fibers formed using the heating melt-blown of PP materials through layer by layer
Compression forms certain thickness hollow circular cylinder filter core, the filter core filter bores aperture that meltblown fibers are formed layer by layer from outside to inside and
Tight ness rating is consistent, and filter core can only carry out a kind of filtering of required precision.It has also been found that, the filter bores of filter core outer layer are often very in use
Just blocked soon by the various impurity in water, influence current by causing the service efficiency of filter core internal layer too low, actually not only contracting
The short Acceptable life of filter core, also actually reduce the utilization benefit of filter core.
One utility model of application number 201220082954.8 entitled " melt-blown filter structure " provides a kind of improvement side
Case, a column is formed using the melt-blown of PP materials, through hole is formed in the middle part of filter core, filter core is by the molten of more than at least two different densities
Spray fibrous layer is combined, and the layered filtration of different accuracy is realized with this, extends the service life of filter core.But consider different densities
Layering meltblown fibers be actually still one it is non-removable, when outer layer low-density meltblown fibers be blocked after, interior floor height
Density meltblown fibers are still to be continuing with, therefore the efficiency problem that still unresolved internal layer service efficiency is too low.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of detachable melt-blown filter structure, it is characterised in that：Including filter core set
What cylinder and sleeve were adapted is placed in the layer of meltblown fibers that in sleeve and adjacent layer is also adapted, and the filter core sleeve includes set
To be covered on cylinder body and sleeve, the layer of meltblown fibers has 2-5 layers and successively density increase, aperture also successively reduce from outside to inside,
The upper and lower ends of every layer of layer of meltblown fibers are all annular hard stainless steel frame, two annulars of the upper and lower ends
It is connected between hard stainless steel frame with stainless steel stent, between strengthening the rigidity of the layer of meltblown fibers, reduce adjacent layer
Coefficient of friction is allowed to easily install.
It is too low and then make filter that detachable melt-blown filter structure provided by the invention thoroughly solves internal layer filter core service efficiency
The problem of core entirety utilization benefit is low, when outer layer meltblown fibers are blocked by impurity, it can be taken off filter core taking out sleeve, by outer layer
Meltblown fibers are changed or go the removal of impurity, and internal layer meltblown fibers can continue to play a role.
Brief description of the drawings
Fig. 1 is the filter core sleeve overall schematic of the present invention.
Fig. 2 is the stainless steel frame structural representation nested layer by layer of the present invention.
Covered on 1- sleeves, 2- sleeve bodies, 3- layer of meltblown fibers upper and lower side annular hard stainless steel frames, 4- stainless steels
Support.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
Such as Fig. 1, a kind of 2 detachable melt-blown filter structures provided by the invention, it is characterised in that：Including filter core sleeve, with
What sleeve was adapted is placed in the layer of meltblown fibers that in sleeve and adjacent layer is also adapted, and the filter core sleeve includes covering on sleeve
1 and sleeve body 2, the layer of meltblown fibers haves three layers and successively density increase, aperture also successively reduce from outside to inside, described every
The upper and lower ends of layer layer of meltblown fibers are all annular hard stainless steel frame 3, two annular hard of the upper and lower ends
It is connected between stainless steel frame 3 with stainless steel stent 4, to strengthen rubbing between the rigidity of the layer of meltblown fibers, reduction adjacent layer
Coefficient is wiped to be allowed to easily install.
It is too low and then make filter that detachable melt-blown filter structure provided by the invention thoroughly solves internal layer filter core service efficiency
The problem of core entirety utilization benefit is low, when outer layer meltblown fibers are blocked by impurity, it can be taken off filter core taking out sleeve, by outer layer
Meltblown fibers are changed or go the removal of impurity, and internal layer meltblown fibers can continue to play a role.
