Abstract
The present invention provides a kind of big flux security personnel filter core, and outer layer filter core can be avoided, which to be blocked up too early by dirt, causes the problem of service life is small, internal layer filter core utilization benefit is low, it is characterised in that：Including upper and lower end cap, internal layer support frame, among filter medium, outer layer fix skeleton, inner layer sleeve, the internal layer support frame, filter medium intermediate layer, outer layer fix skeleton close fit together, be fitted on inner layer sleeve and up and down at end cap of filter core be fixed on by hot melt adhesion, the filter medium intermediate layer is the fold shape for the polypropylene material that density gradually increases from outside to inside, hole is gradually reduced, and the internal layer support frame, outer layer fix skeleton and be stainless steel grid and be adapted with the fold shape in filter medium intermediate layer.
Description
Technical field
The present invention relates to water treatment field, is a kind of big flux filter core, more particularly to big logical in a kind of water treatment process
Amount security personnel's filter core.
Background technology
Security personnel's filtering refers to water from microstraining core（Precision is generally less than 5 μm）Outside enter filter core inside, trace suspension
Thing or fine impurities particulate matter are trapped within the process outside filter core.Cartridge filter also known as accurate filter, are generally located on
Before pressure vessel, to remove the fine particles of more than 1 degree of turbidity, to meet requirement of the subsequent handling to water inlet；Sometimes also set
Put in the end of whole water treatment system, to prevent fine particles from entering product water.From structure, cartridge filter mainly by
Filter shell, filter core etc. form, and filter shell is largely R304 stainless steels, is such as used in acid and alkali-resistance special occasions
Then shell can be done using R316 stainless steels, flange form and clamping hoop type can be divided into, it is larger that flange form shell is used primarily in filtering traffic
Occasion.Filter core mainly also uses Wire-wound filter core or active carbon filter core, the installation number of filter core using PP filtering cotton cores, some occasions
It can mainly be determined from one to tens according to the size for the treatment of capacity.
But this filter core flux is small, easy to be dirty stifled, replacement frequency is big, can not meet big flux term purpose requirement.It is and common
Foldable filter element typically there are angular structures, can there are problems that in use, for example, filter core long-time carry out water process work
After work, due to being impacted by current, adjacent several folds can press together the fold of filter core, so on the one hand cause dirt
Dye thing can be deposited at these folds, accelerate the dirt of filter core to block up, the pressure drop of filter core increases rapidly；On the other hand, due to part pleat
Wrinkle is pressed together, and reduces the effective filtration area of filter core, and contamination capacity DHC is reduced.Therefore, this flux is small, easy dirt is stifled,
Replacement frequency is big, can not meet big flux term purpose needs, need to improve.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of big flux security personnel filter core, it is characterised in that：Including upper and lower side
Among lid, internal layer support frame, filter medium, outer layer fix skeleton, inner layer sleeve, the internal layer support frame, filter medium
Intermediate layer, outer layer fix skeleton close fit together, be fitted on inner layer sleeve and filter core be fixed on by hot melt adhesion
At upper and lower end cap, the filter medium intermediate layer is the polypropylene material that density gradually increases from outside to inside, hole is gradually reduced
Fold shape, the internal layer support frame, outer layer fix skeleton be stainless steel grid and with the pleat in filter medium intermediate layer
Wrinkle shape is adapted.
A kind of filter medium intermediate layer of big flux security personnel filter core provided by the invention is formed in one structure, is used for
Increase contamination capacity can avoid flux caused by the blocking of outer layer filter cloth from declining phenomenon, improve filter core service life.Simultaneously as increase
Add internal layer to fix skeleton, outer layer fixation skeleton, when filter core is by water impact, has avoided adjacent pleats from being squeezed together and make
Into dead angle, to greatest extent using the filter area in filter medium intermediate layer, increase the contamination capacity of filter core, can also reduce pressure difference.
Brief description of the drawings
Fig. 1 is the overall separation structure schematic diagram of the present invention.
Fig. 2 is the part section structural representation that the filter medium intermediate layer of the present invention and ectonexine fix skeleton.
Fig. 3 is the overall schematic of the present invention.
End cap, 2- filter mediums intermediate layer and ectonexine fix skeleton assembly to 1- up and down, and 21- internal layers fix skeleton, 22-
Filter medium intermediate layer, 23- outer layers fix skeleton, 3- inner layer sleeves.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
Such as a kind of big flux security personnel filter core provided by the invention of Fig. 1,2,3, it is characterised in that：Including upper and lower end cap 1,
Internal layer support frame 21, filter medium intermediate layer 22, outer layer fixation skeleton 23, inner layer sleeve 3, the internal layer support frame 21,
Filter medium intermediate layer 22, outer layer fix skeleton 23 close fit together, be fitted on inner layer sleeve 3 and viscous by heating
Connect at the end cap up and down 1 for being fixed on filter core, the filter medium intermediate layer 22 gradually increases for density from outside to inside, hole is gradual
The fold shape of the polypropylene material of reduction, the internal layer support frame 21, outer layer fix skeleton 23 be stainless steel grid simultaneously
It is adapted with the fold shape in filter medium intermediate layer 22.
A kind of filter medium intermediate layer 22 of big flux security personnel filter core provided by the invention is formed in one structure, uses
To increase contamination capacity flux caused by the blocking of outer layer filter cloth can be avoided to decline phenomenon, improve filter core service life.Simultaneously as
Add internal layer and fix skeleton 21, outer layer fixation skeleton 23, when filter core is by water impact, avoid adjacent pleats from being squeezed
Dead angle is caused together, to greatest extent using the filter area in filter medium intermediate layer 22, is increased the contamination capacity of filter core, can also be dropped
Low voltage difference.
Claims (1)
