Description
Technical field
The utility model belongs to filter technology field, is concretely related to a kind of air filter.
Background technique
Air filter (as shown in Figure 1) by tubular construction filter core 1 and be respectively arranged at the upper and lower end 2,3 of the filter core
Back cover 4 and the flange nozzle 6 that can be connect with pipeline 5 constitute；Induced draft fans 7 will enter filter by outside by pipeline when use
The filtered air of core is extracted out by the central passage 8 of filter core, to realize the filtering to air；After using the time of setting, by
It is deteriorated in the activity for the adsorbing contaminant for constituting the active carbon in filter core, the filter core or entire filter that can more renew.But constituting should
In the tubular filter core of structural gap filter active carbon layer be uniformly arranged, therefore its close to filter core bottom active carbon benefit
It is relatively low with rate, and it is just higher close to the utilization rate of the active carbon of end thereon, therefore just will form the activity on 11 top of oblique line
The activity of charcoal 21 is deteriorated, but the active carbon 22 of oblique line lower part still has the good activity for capableing of adsorbing contaminant；It changes the filter
Core is a kind of waste.
Utility model content
The purpose of this utility model is just to provide the sky that a kind of structure is simple and can easily use filter core inversion
Air filter.
To achieve the above object, the technology employed by the present utility model is
A kind of air filter, including tubular filter core；It is separately provided in the upper and lower end portion of the tubular filter core solid
The upper and lower annular end cap of the fixed filter core, is provided with sealed end that is fixed thereto and can dismounting on the lower annular end cap
Lid, is provided with the flange that can be connect with pipeline that is fixed thereto and can dismounting on the upper annular end cap.
Constitute a kind of additional technical feature of above-mentioned air filter further include:
--- it fixes or connects and fixes by screw between the lower annular end cap and end cover；The upper annular end
It fixes or connects and fixes by screw between lid and flange；
--- sealing rubber ring is provided between the upper annular end cap and flange；
--- sealing rubber ring is provided between the lower annular end cap and end cover；
--- the end cover centre is in recessed cylinder corresponding with the central passage of the tubular filter core；
--- the depth of the recessed cylinder is arranged in 1/6th of the tubular filter core length between a quarter.
A kind of air filter provided by the utility model compared with the existing technology, have the advantage that first, due to
It is separately provided for fixing the upper and lower annular end cap of the filter core in the upper and lower end portion for the tubular filter core for constituting the filter,
End cover that is fixed thereto and can dismounting is provided on lower annular end cap, be provided on upper annular end cap it is fixed thereto simultaneously
The flange that can be connect with pipeline that can be dismounted, therefore after the filtration core for being provided with active carbon is using the time of setting, it can
By the way that filtration core is removed and is reused after turned upside down installation, it can so that the activity that original lower part does not make full use of
Charcoal inversion is fully used to the upper end of air filter, can not only extend the service life of filter, Er Qiejie
About resource；Second, since the end cover centre for being set to filter core bottom is in corresponding with the central passage of tubular filter core
Recessed cylinder, therefore can control filter core active carbon use the time, can to filter core turned upside down use when active carbon use
Effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of prior art air filter；
Fig. 2 is a kind of structural schematic diagram of air filter of the utility model.
Specific embodiment
The structure and working principle of a kind of air filter provided by the utility model are made into one with reference to the accompanying drawing
The detailed description of step.
It referring to fig. 2, is a kind of structural schematic diagram of air filter provided by the utility model.Constitute the air filtration
The structure of device includes tubular filter core 1, the upper and lower end of the tubular filter core 3,2 be separately provided for fixing the filter core it is upper,
Lower annular end cap 10,9 is provided with the sealing of screw 13 fixed (in order to be able to easily dismounting) on lower annular end cap
End cap 12, be provided with screw 13 fixed (in order to be able to easily dismounting) on upper annular end cap can be with pipeline 5
The flange 6 of connection；Sealing is provided between lower annular end cap 9 and end cover 12 and between upper annular end cap 10 and flange 6
Ring 14.
Its working principle is that: starting 7 air of exhaust fan is oblique into filter core along arrow F, will be in air through active carbon layer
After dust and solid impurity absorption, filtered air enters in central passage 8 and is exported by flange by pipeline；When one section of use
Since the absorption property of the active carbon 21 along 11 top of oblique line is deteriorated after time, then upper and lower annular end cap is fixed on by laying down
10, after 9 screw 13,1 turned upside down of filter core (or fixing end cover and flange transposition) reuses i.e. so that original place
Active carbon in lower end is fully utilized.
In constituting a kind of above-mentioned structure of air filter,
--- it can both be fixed, be also possible between the two by screw between above-mentioned lower annular end cap 9 and end cover 12
It connects and fixes, purpose convenient for disassembly and assembly between the two also may be implemented, that is, facilitate the dismounting of end cover 12 and lower annular end cap 9
And the inversion of filter cylinder uses；Structure between above-mentioned upper annular end cap 10 and flange 6 is same；
--- in order to control the active control of active carbon in tubular filter core, i.e., it will not be formed in use process oblique line 11
The active carbon transition of above part consumes, so that oblique line 11 declines in the bottom of tubular filter core, then is inverted tubular filter core, will be upper
It states end cover centre and is arranged to recessed cylinder 15 corresponding with the central passage 8 of tubular filter core, which can prevent down
Consumption of the outside air of end to corresponding 11 or less active carbon of tubular filter core bend；It can be with according to the service life of filter core
The depth H setting of recessed cylinder is designed 1/6th of above-mentioned tubular filter core length (namely height) between a quarter；I.e. this is recessed
The depth of cylinder determines this upper and lower position of oblique line 11 in filtration cartridges: the more deep corresponding oblique line 11 of the depth H of recessed cylinder is more top, on the contrary
Following side can be located at.
