Specific implementation mode
To keep the purpose, technical scheme and advantage of this patent clearer, below in conjunction in the utility model embodiment
Attached drawing, the technical scheme in the utility model embodiment is clearly and completely described, below in conjunction with the accompanying drawings with specific reality
Mode is applied to be described in further detail the utility model.
The utility model provides a kind of ladder filtering type filter core, including：Filter layer, filter layer be inner hollow and with the external world
Perforation, filter layer inner hollow flows through filter layer outside filter layer and enters filter layer inner hollow for storing or exporting
Fluid, it to quality is in closely step increments that the filter material density of filter layer is loose from quality from outside to inside.
The basic demand of filter core is filtered to the fluid for flowing through filter material, adsorb liquid in some particulate matters, impurity,
The harmful substance such as chlorine, the harmful substance in liquid is reduced in acceptability limit, by filter core on this basis
Internal structure design is density step increments, enhances the filtering traffic in the unit interval, loose in filter core filter material quality
In the range of, the density of filter layer is larger, and flow rate of liquid is very fast, can also obstruct the particle that a part is relatively large in diameter, simultaneously
There is certain adsorption capacity to some magazines and noxious material, there is the dense of the impurity and noxious material centainly reduced in liquid
The ability of degree；It is traveled further into the more close range of filter core filter material in liquid, flow velocity has certain decline, and same barrier is fallen
The particle of a part of diameter, while having certain enhancing to the adsorption capacity of impurity and noxious material in liquid, further drop
The concentration of impurity and noxious material in low liquid；And so on, filter core filter material density is carried out continuing to increase, is realized to smaller
The absorption of the barrier of diameter particle and impurity, noxious material.
Selection for the number of plies of the filter material density step increments to filter layer, be to the rate of filtration and filter capacity it
Between index coordinate as a result, when the ladder number of plies is excessive, ultimate attainment, the filter material density of filter layer will present linear distribution, although
Have iris action still because layering excessively will appear a kind of two kinds of extreme, situation progress thickness thickenings a variety of particles, though
So it ensure that absorption and obstructing capacity, but the rate of filtration is difficult to ensure；Another situation is to ensure that overall thickness is constant to every layer
Thickness carries out skiving, although can be ensured by the time liquid, because every layer of thickness is all very thin, although ensure that resistance
Every the ability of particle, but layered structure excessive on the whole reduces the ability of absorption noxious material.
If filter core of the selection such as the same filter material density in current technology, the institute other than a kind of diameter can be obstructed
There are particle, cartridge surface to need, in face of the amounts of particles much larger than its ability to bear, cartridge surface can be caused complete by particle quickly
All standing, but still possess a large amount of gaps inside filter core for adsorbing, but subsequent liquid can not be gone successively in filter core, reduce filter
The service life of core wastes a large amount of vacant filter material.Meanwhile this structured filter speed is also poor, and can be after use
The case where rate of filtration die-offs is presented in phase.
First embodiment：
Please with reference to Fig. 1, Fig. 2 and Fig. 3, in the first embodiment of the utility model, filtering velocity is crossed in order to coordinate liquid
Degree and filter capacity, filter layer 1 are the Carbon fibe and activated carbon powder compound of cylindrical shape, and the hollow space of cylinder will be for that will filter
Liquid afterwards is stored or is exported, and the material of Carbon fibe and activated carbon powder compound is easy to be molded and press, production process
In the control of 1 density of filter layer is relatively easy to.Meanwhile Carbon fibe and activated carbon powder compound are to various impurity and noxious material
Adsorption capacity it is very strong, disclosure satisfy that the requirement of product filter capacity.
Filter layer 1 includes three layers：The filter material density domination of outer layer 11, middle level 12 and internal layer 13, outer layer 11 is allowing diameter
Particle and particle less than 30 μm pass through, and the filter material density domination in middle level 12 is allowing particle of the diameter less than 10 μm and particle logical
It crosses, the filter material density of internal layer 13 allows to control to be passed through in particle of the diameter less than 5 μm and particle.
The filter material of outer layer 11 can obstruct particle of the diameter more than 30 μm and particle passes through, and diameter is less than 30 μm of particle
Passed through with particle, liquid is filtered through speed, but because only particle of the meeting diameter more than 30 μm and particle can be hindered
Every, therefore surface of filter medium is capped complete speed and substantially reduces.
The diameter of particle and particle into outer layer 11 is already confined to 30 μm hereinafter, therefore the filter material in middle level 12 can
Barrier diameter is more than 10 μm and the particle less than 30 μm and particle passes through, and liquid is filtered through that speed is opposite to be weakened, because of filter material
Only barrier diameter is more than 10 μm and particle and particle less than 30 μm, therefore the speed that surface is completely covered is more slow.
The diameter of particle and particle into middle level 12 is already confined to 10 μm once, therefore the filter material of internal layer 13 can
Barrier diameter is more than 5 μm and passes through with the particle less than 10 μm and particle, and it is the slowest that liquid is filtered through speed, to impurity,
The Adsorption ability of noxious material and chlorine is most strong because filter material only obstruct diameter more than 5 μm and the particle less than 10 μm and
Grain, the speed that surface is completely covered are the slowest.
The service life speed that all thus three layers of density filter core are completely covered of entire filter layer 1 determines, when outer layer 11,
Any surface of middle level 12 and internal layer 13 is completely covered, this filter core can not be continuing with, but outer layer 11, middle level 12 and internal layer
13 increase surface of filter medium area, speed is completely covered compares and substantially reduced using the filter layer 1 of a filter material density, use the longevity
Life greatly enhances；Meanwhile the particle of three layers of density filter core selection barrier is different with the diameter of particle, needs the particle obstructed
It is shared among outer layer 11, middle level 12 and internal layer 13 with particle, corresponding every layer of filtering quantity also accordingly reduces, therefore outer layer
11, the speed that middle level 12 and 13 surface of internal layer are completely covered further decreases, then the service life of filter core further enhances.
In order to realize that the thickness ratio of outer layer 11, middle level 12 and internal layer 13 is 1 to chlorine residue better place to go effect:2:4, because
For the removal ability for requiring to chlorine residue in filter core functional parameter, filter core depends on filter core filter material to the adsorption capacity of chlorine residue
Density, the larger filter core filter material of density is also stronger to the place to go ability of chlorine residue, therefore, in order to reach the finger of removal chlorine residue ability
Mark needs the thickness for accordingly thickening the larger internal layer 13 of filter core filter material density, enhances place to go ability of the entire filter core to chlorine residue.It is logical
The thickness ratio for crossing control outer layer 11, middle level 12 and internal layer 13 is 1:2:4, the liquid flow velocity of outer layer 11 is very fast.To chlorine residue
Place to go ability is 20%；The liquid flow velocity opposed outer layer 11 in middle level 12 is slack-off, and the place to go ability to chlorine residue is 30%；Internal layer
13 liquid flow velocity becomes slower with respect to middle level 13, and the place to go ability to chlorine residue is 50%.
Specifically, the thickness of filter layer 1 is between 5mm to 30mm, the diameter of inner hollow between 8mm to 50mm it
Between.The thickness of filter layer 1 is controlled between 5mm to 30mm, ensures the ratio between 1 inner hollow of filter layer and filter layer 1, is protected
The inner hollow of card filter layer 1 in time exports filtered liquid, prevents the thickness because of inner hollow for the thickness of filter layer 1
Degree ratio, it is too small to cause liquid to remain in inner hollow to export in time, cause liquid pressure subtractive inside and outside filter layer 1 small
Influence the rate of filtration.The diameter of the inner hollow of filter layer 1 is between 8mm to 50mm, the opposite both sides substantially symmetrical about its central axis of filter layer 1
The sum of 1 thickness of filter layer is between 10mm to 60mm, then the ratio between inner hollow and filter layer 1 is stablized near 1, in internal
Sky can export filtered liquid in time.
Fig. 4 is please referred to, Fig. 4 is filter core provided by the utility model and time used in existing filter element filtering same traffic liquid
Comparison diagram.In order to ensure to filter index, existing filter core generally selects the material for core less than 5 μm, this comparison diagram is using 5 μm
Material for core, which is used as, refers to object, this comparison example controls the thickness one of existing filter core and filter core provided by the utility model simultaneously
It causes, filter core provided by the utility model is equally reached the requirement of filtering index, liquid pressure inside and outside control filter core thickness, filter core
By force, filtering each variable of index is consistent, and the time of the liquid of existing filter element filtering same volume flow is considerably longer than the utility model
The filter core of offer, because existing filter core is filtered using 5 μm of consistent material for core, therefore than 5 μm of filter core provided by the utility model
The thickness of core material increases at least two times, and filtration time increases significantly；Filter core provided by the utility model uses three layers of filter core
Material, outer layer 11 and the 12 liquid rate of filtration of middle level are compared the 13 liquid rate of filtration of internal layer and are greatly enhanced, and 5 μm of internal layer 13 filters
The thickness of core material is again smaller than the existing filter core for using 5 μm of consistent material for core, and filtration time also accordingly shortens, by three
The combination of layer material for core reach it is even better reach filtering index while, greatly strengthen the rate of filtration, and existing
Filter core needs as far as possible to increase filter core density, phase using the material for core of consistent in density in order to reach filtering index request
That answers sacrifices the rate of filtration.
Fig. 5 is please referred to, Fig. 5 is the comparison diagram of filter core provided by the utility model and existing filter core service life.In order to protect
Card filtering index, existing filter core generally select the material for core less than 5 μm, this comparison diagram is using 5 μm of material for core as ginseng
Object is examined, therefore existing filter core can obstruct particle of all diameters more than 5 μm and particle and be attached to surface, it is straight more than 5 μm
Diameter range is very wide in range, and corresponding particle and number of particles also can be very huge, therefore surface can be various in use
Particle attachment blocks, and filter core can not continue to filter soon, and still has the ability for continuing filtering inside filter core；This
Utility model uses three layers of material for core, is equivalent to the surface area for providing and being three times in prior art filter core, meanwhile, mistake respectively
Particle and particle that diameter is more than 30 μm are filtered, diameter is more than 10 μm of particles and particle for being less than 30 μm, and diameter is more than 5 μm and is less than 10
μm particle and particle, particle to filtering and particle carry out selective filter, the number of particle and particle that correspondence can obstruct
Amount is just obstructed by the filter material of each density respectively, the corresponding quantity being blocked also accordingly is reduced, therefore surface is completely covered
Speed slows down significantly, and filter core service life greatly increases.And the specific service life of the utility model is by outer layer 11, middle level
12, the speed that any layer in internal layer 13 is completely covered determines, the different use longevity is had according to different use environments
Life, but generally, in most routine use environment, the service life of the utility model is considerably longer than existing filter core.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution, improvement and etc. done should be included in the utility model
Within the scope of protection.
