Description
Technical field
The present invention relates to air filter unit technical field, particularly relate to a kind of blower fan filtering unit.
Background technology
Clean room and ultra-clean chamber are widely used in electronic workshop, bio-pharmaceuticals laboratory, hospital surgical
Room or laboratory etc..In clean room, most important Con trolling index is cleanliness factor, it is ensured that splendid is clean
Between Jing, cleanliness factor is to protect for the quality that the production in clean room and experimental result are most basic
Card.Clean air quantity in high-level clean room relies primarily on blower fan filtering unit and carries.Blower fan
The advantage of filter element is the air that air conditioning unit conveying comes to be carried out ultra-clean filtration,
Small particle can control to no more than 0.3um, and is transported in the clean environment of servo by blower fan,
Ensure clean environment with this, reach clean or ultra-clean requirement.
Blower fan filtering unit includes filter, cover body, blower fan and block terminal, filter tight ground
Being embedded into the aperture position of cover body, assembling is in the bottom of cover body, positioned opposite with filter；
Distribution closes and is connected with blower fan, is used for controlling blower fan work.During use, by the edge of opening of cover body
Fasten hermetically on the carriage formed on the ceiling, make filter and cover body by carriage
Supporting.During work, open blower fan by block terminal, under blower fan drives, air conditioning unit conveying
Air be admitted in cover body, owing to other positions of cover body are all closed, air can only be from filter
Pass through, filter filtered air enter clean room through carriage, so that clean room
Air reaches purity requirements.
In use, the cover body of blower fan filtering unit is continuous running parts, is not related to disappear
The problems such as consumption, but the filter of cover body aperture position is by the continuous pollution of outside air, empty
Adjusting unit limited filtering capacity, filter exceedes the reasons such as service life, needs periodically to carry out more
Change, to ensure the clean requirement of clean room or ultra-clean chamber.Filter is arranged on carriage, and
It is embedded into closely in cover body, to ensure that other pollutions extraneous will not be between cover body and filter
Gap enters in clean room.When filter replacement, need to lift cover body entirety to remove,
Just can carry out the replacing of filter.Owing to high-level clean room top is all large-area blower fan mistake
Filter unit is abound with, and is the hugest and to expend personnel a large amount of for changing the workload of filter
Blue-collar work, and the cover body removed in Renewal process can not pile up other cover body it
On, operating process has great difficulty.Traditional blower fan filtering unit needs when changing filter
Whole cover body entirety is lifted and put down, and owing to the weight of cover body own is the most heavy, and edge is the sharpest
Sharp, after changing brand-new filter, the when that cover body being placed on above filter,
Sharp-pointed for the edge of cover body place may be touched during fan box para-position or personnel are moved cover body
Contact brand-new filter, cause the damage of filter.
Therefore, for above-mentioned a kind of blower fan filtering unit of not enough needs, ensureing that air filtration is clean
On the premise of clean effect, it is simple to change, ensure clean requirement with this.

Detailed description of the invention
Make to retouch the most in detail to the detailed description of the invention of the present invention with embodiment below in conjunction with the accompanying drawings
State.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
As it is shown in figure 1, the blower fan filtering unit of the present invention, including cover body 1, filter 7, wind
Machine 3 and block terminal 2.Cover body 1 is made up of steel, aluminium alloy or copper alloy, and it has an opening,
Filter 7 is entrenched in the aperture position of cover body 1.Blower fan 3 is connected on cover body 1, concrete,
Blower fan 3 and filter 7 are oppositely disposed at bottom cover body 1.Block terminal 2 is arranged on cover body 1
Bottom outer wall on, be connected with blower fan 3, for controlling the work of blower fan 3, as controlled blower fan 3
Switch or regulation blower fan 3 speed.This filter element also includes a cover plate 4, cover body 1
Bottom be provided with an installation through hole 11, for passing through for filter 7.Cover plate 4 is by hinge 5
It is rotatably coupled and is arranged on cover body 1, be used for covering installation through hole 11.Preferably, cover body
1 is rectangular cover, and the sidewall of rectangular cover is surrounded by long sidewall 14 and broad side walls 13, installs through hole
11 is rectangular, and is arranged on the cover body 1 side near broad side walls 13.
Further, the edge installing through hole 11 is provided with sealing ring 12, improves and installs through hole 11
Sealing property after covering.
Further, between cover body 1 and cover plate 4, it is additionally provided with snap close 6, is used for pinning cover plate.
Further, the cross section of the aperture position of cover body 1 is less than the cross section of bottom.Preferably
, the medial wall of cover body 1 has 0.1～2 ° of gradient, makes aperture position transversal of cover body 1
Face is less than the cross section of bottom.When filter 7 is installed into cover from the bottom of cover body installation through hole
During body, filter can be preferably chimeric with cover body aperture position, improves filter and cover body
Tightness.
Preferably, the end of filter 7 has to hold draws portion's (not shown), is convenient to construction
Personnel's installation and removal are held and are taken.
During use, the opening of cover body 1 is buckled on the carriage of ceiling mounted formation,
Make edge of opening fit with carriage, open cover plate 4, from installing through hole 11 by filter 7
It is installed to the aperture position of cover body 1, covers cover plate 4, and pin cover plate with snap close.When needs more
When changing filter, first the cover plate 4 on cover body 1 is opened installation through hole 11, utilize front end in
Hook-shaped rod shape instrument, deeply installs in through hole 11, catches on the filter of lower section by holding a portion
7, the most slowly mention, filter 7 is taken out smoothly by installing through hole 11；Then, will
Ready brand-new filter 7 removes outer package both hands and holds both sides frame and slowly pass through cover body
The installation through hole 11 of 1 is put into, and again covers cover plate 4, completes the replacing of filter.
In sum, the blower fan filtering unit of the present invention, when changing filter, it is not necessary to will
Whole cover body is pulled down, and Renewal process is convenient and swift, saves substantial amounts of manpower, reduces the damage of cover body
Bad, improve filter effect.Concrete:
1, by the installation through hole just replaceable filter at cover body above blower fan filtering unit, whole
Individual operating process one people is the most operable in ten minutes completes, it is to avoid more than two people operates and lifts
The operation of cover body, saves manpower and activity duration, also saves the physical labor intensity of personnel,
Make operating process more simple and efficient.
2, brand-new filter is preferably protected.Installation through hole bottom cover body changes filter,
Without mobile cover body, the damage to filter can be avoided the most completely.
3, stop personnel and article to fall from blank region.During changing filter, will cover
During body and filter are all removed, the whole position of framework on ceiling and lower floor
Clean room communicates, and the height of general clean room at least at three to five meters, falls if any personnel
Fall behind fruit hardly imaginable, drop equipment or the personnel of clean room can be impacted if any article.
And the installation through hole bottom cover body changes high efficiency particulate air filter, do not have blank position and occur, keep away
Exempt from that the accidents such as personnel's injury occur.
The above is only the preferred embodiment of the present invention, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from the technology of the present invention principle, it is also possible to
Making some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
