Description
Technical field
The present invention relates to air filter unit technical field, particularly relate to a kind of blower fan filtering unit.
Background technique
Clean room and ultra-clean chamber are widely used in electronic workshop, bio-pharmaceuticals laboratory, hospital operating room or laboratory etc.In clean room, most important Con trolling index is cleanliness, ensures that splendid clean room cleanliness is for the production in clean room and the most basic QA Quality Assurance of experimental result.Clean air quantity in high-level clean room mainly relies on blower fan filtering unit to carry.The advantage of blower fan filtering unit is that the air that air-conditioner set can be transported carries out ultra-clean filtration, and minimum grain size can control to and be not more than 0.3um, and is transported in the clean environment of servo by blower fan, ensures clean environment with this, reaches clean or ultra-clean requirement.
Blower fan filtering unit comprises filter, cover body, blower fan and block terminal, is embedded into the aperture position of cover body filter tight, and assembling is in the bottom of cover body, positioned opposite with filter; Distribution closes and is connected with blower fan, for controlling blower fan work.During use, the edge of opening of cover body is fastened on the supporting frame formed on the ceiling hermetically, filter and cover body are supported by supporting frame.During work, blower fan is opened by block terminal, under blower fan drives, the air of air-conditioner set conveying is admitted in cover body, because other positions of cover body are all closed, air can only pass through from filter, enters clean room by air permeable supporting frame after metre filter, thus makes the air of clean room reach purity requirements.
In use, the cover body of blower fan filtering unit is continuous running parts, do not relate to the problems such as consumption, but the filter of cover body aperture position is subject to the continuous pollution of ambient air, air-conditioner set limited filtering capacity, filter exceedes the reasons such as working life, needs regularly to change, to ensure the clean requirement of clean room or ultra-clean chamber.Filter is arranged on supporting frame, and is embedded into closely in cover body, to ensure that other pollutions extraneous can not enter in clean room from the gap between cover body and filter.When filter replacement, need cover body entirety to lift to remove, just can carry out the replacing of filter.Because high-level clean room top is all that large-area blower fan filtering unit is abound with, workload for replacing filter is extremely huge and expends a large amount of blue-collar work of personnel, and the cover body removed in Renewal process can not pile up on other cover body, operating process has great difficulty.Traditional blower fan filtering unit needs whole cover body entirety to lift and put down when changing filter, because the weight of cover body own is very heavy, and edge is comparatively sharp-pointed, after changing brand-new filter, time cover body is placed on above filter, fan box contraposition or personnel being moved in cover body process and sharp-pointed for the edge of cover body place may being touched brand-new filter, cause the damage of filter.
Therefore, need a kind of blower fan filtering unit for above-mentioned deficiency, under the prerequisite ensureing the clean effect of air-filtering, be convenient to change, ensure clean requirement with this.

In figure, 1: cover body; 2: block terminal; 3: blower fan; 4: cover plate; 5: hinge; 6: snap close; 7: filter; 11: through hole is installed; 12: seal ring; 13: broad side walls; 14: long sidewall.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, blower fan filtering unit of the present invention, comprises cover body 1, filter 7, blower fan 3 and block terminal 2.Cover body 1 is made up of steel, aluminum alloy or Cuprum alloy, and it has an opening, and filter 7 is entrenched in the aperture position of cover body 1.Blower fan 3 is connected on cover body 1, concrete, and blower fan 3 and filter 7 are relatively arranged on bottom cover body 1.Block terminal 2 is arranged in the bottom outer wall of cover body 1, is connected with blower fan 3, for controlling the work of blower fan 3, as controlled the switch of blower fan 3 or regulating the speed of blower fan 3.This filter element also comprises a cover plate 4, and the bottom of cover body 1 is provided with an installation through hole 11, for passing through for filter 7.Cover plate 4 is mounted on cover body 1 by hinge 5 rotationally, installs through hole 11 for covering.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 rectangular, and is arranged on the side of cover body 1 near broad side walls 13.
Further, the edge installing through hole 11 is provided with seal ring 12, improves and installs the sealability of through hole 11 after covering.
Further, between cover body 1 and cover plate 4, be also provided with snap close 6, 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 madial wall of cover body 1 has 0.1 ~ 2 ° of inclination, makes the cross section of the aperture position of cover body 1 be less than the cross section of bottom.When filter 7 is installed into cover body from the bottom installation through hole of cover body, filter can be chimeric with cover body aperture position preferably, improves the tightness of filter and cover body.
Preferably, the end of filter 7 has to hold draws portion's (scheming not shown), is convenient to workmen's installation and removal and holds and take.
During use, the opening of cover body 1 is buckled on supporting frame that installation formed on the ceiling, edge of opening and supporting frame are fitted, opens cover plate 4, from the aperture position installing through hole 11 and to be installed to by filter 7 cover body 1, cover cover plate 4, and pin cover plate with snap close.When filter changed by needs, first by the cover plate 4 opening installation through hole 11 on cover body 1, front end is utilized to be hook-shaped rod shape instrument, deeply install in through hole 11, catching on the filter 7 of below by holding a portion, slowly mentioning afterwards, filter 7 is taken out smoothly by installing through hole 11; Then, ready brand-new filter 7 is removed exterior package both hands and hold both sides frame and slowly put into by the installation through hole 11 of cover body 1, again cover cover plate 4, complete the replacing of filter.
In sum, blower fan filtering unit of the present invention, when changing filter, do not need whole cover body to pull down, Renewal process is convenient and swift, saves a large amount of manpowers, reduces the damage of cover body, improves filtering effect.Concrete:
1, by the installation through hole just replaceable filter at cover body place above blower fan filtering unit, whole operating process one people just can operate in ten minutes, avoid the operation that cover body is lifted in more than two people operation, save manpower and activity duration, also save the physical labor intensity of personnel, make operating process more simple and efficient.
2, brand-new filter is protected better.Change filter from the installation through hole bottom cover body, without the need to mobile cover body, therefore can avoid the damage to filter completely.
3, personnel are stopped and article fall from blank region.During replacing filter, in the process that cover body and filter are all removed, the whole position of framework on ceiling board communicates with the clean room of lower floor, the height of general clean room is at least at three to five meters, hardly imaginable if any personnel's consequence that drops, drop can impact the equipment of clean room or personnel if any article.And change high efficiency particulate air filter from the installation through hole bottom cover body, not having blank position occurs, avoids occurring the accidents such as personnel injure.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
