Abstract
The utility model discloses a harmful gas purifies updraft ventilator aims at a simple structure, and low in manufacturing cost, filter layer change conveniently, purification updraft ventilator that the purifying rate is high. The utility model discloses a following technical scheme realizes: two air exhauster (2) set up respectively in aiutage (3) preceding tip suction opening (1) and back tip gas vent (7) aiutage passageway, are equipped with the at least two -stage filtration who arranges along axial direction parallel in the aiutage passageway and purify mesh screen (5), and every grade of filtration purification mesh screen all is equipped with to purify changes end cover (6). The utility model discloses an every grade of change end cover that the filtration purification mesh screen set up, the filter layer is changed conveniently. The multi -stage filtration who sets up in the aiutage passageway purifies the mesh screen and has improved the purifying rate.
Description
Technical field
The utility model relates to a kind of cleaning harmful gas extractor fan, especially for when retouching the various paint of painting, and the cleaning harmful gas extractor fan in retouching paint and covering.
Background technology
Air cleaning unit designs mainly for operating room, the carbon dioxide (CO be used in filtering confined space
2), carbon monoxide (CO), methane (CH
4), hydrogen sulfide (H
2the toxic and harmful such as S), also can steam in filtering air and stink etc., simultaneously according to hedging number adjustment release oxygen.Prior art air cleaning unit utilizes storage pressure to drive clearing machine work, clearing machine is according to the filtering purification feature of different pernicious gas, same equipment adopts flow to carry out governor motor power, and modulating high-power Pneumatic fan provides large ventilation to carry out the pernicious gases such as filtering CO; This purifier adopts compressed air or nitrogen to promote separately Pneumatic fan work, adopt the draft type of lower exhausting, namely during Pneumatic fan work, be vented outside case thus make to form negative pressuren zone in purification casing, gas flow in confined space is through chemical drugs oxidant layer, enter in purification casing, and along with the suction of Pneumatic fan is discharged to outside purifying box.Pernicious gas carries out chemical reaction or catalytic reaction through chemical drugs oxidant layer and chemical agent, is transformed into solid matter or other gas, to reach the object of filtering purification.The extractor fan volume of prior art air cleaning unit is large, and purification filtering mode is complicated, and chemical drugs oxidant layer is changed inconvenient, and equipment cost is high, and uses when just reprocessing part coating removal, oil removing for factory.And retouch without extractor fan in paint cover, retouching in paint process, pernicious gas is discharged into by the exhaust outlet retouching paint cover self and retouches paint room, and the health of operator is endangered.Extractor fan plays the effect of exhaust, and can purifying harmful gas.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the utility model provides a kind of structure simple, low cost of manufacture, and filter course is changed convenient, the cleaning harmful gas extractor fan that purifying rate is high.
The utility model solves the technical scheme that its technical problem adopts: a kind of cleaning harmful gas extractor fan, comprise: aiutage bracing frame and air exhauster, it is characterized in that: two air exhausters 2 are separately positioned in aiutage 3 leading section suction opeing 1 and rearward end exhaust outlet 7 aiutage passage, be provided with at least double-filtration purification mesh screen 5 arranged in parallel vertically in aiutage passage, every grade of filtration, purification mesh screen is all provided with purification and changes end cap 6.
The utility model has following beneficial effect compared to prior art.
Structure is simple, low cost of manufacture.The utility model is adopted use two air exhausters (2) be separately positioned in aiutage leading section suction opeing and rearward end vent cylinder passage and is formed exhaust passage, the active carbon of purifying harmful gas can be reused, structure is very simple, and manufacturing cost is not high.Body weight is light, and volume is little, is conveniently placed on and retouches in paint cover.Solve prior art and retouch the interior defect without extractor fan of paint cover.
Filter course is changed convenient, and purifying rate is high.The replacing end cap that the utility model every grade filtration, purification mesh screen is arranged, filter course is changed convenient.The multi-stage filtration purifying mesh screen arranged in aiutage passage improves purifying rate, the utility model retouch paint cover in can move with hand, by suction opeing aligning retouch directly over part.Also the position of extractor fan can be adjusted according to the actual needs retouching lacquerer.Thus reach the object purifying and retouch and paint the air in covering and safety dumping.
Accompanying drawing explanation
Fig. 1 is the stereogram of cleaning harmful gas extractor fan.
In figure: 1 leading section exhausting, 2 air exhausters, 3 aiutages, 4 aiutage bracing frames, 5 filtration, purification nets, 6 purifications change end cap, rearward end exhaust outlet 7.
Detailed description of the invention
Be described in further detail with accompanying drawing 1 pair of the utility model below in conjunction with actual.
With reference to accompanying drawing 1.A kind of cleaning harmful gas extractor fan comprises: aiutage bracing frame 4 and air exhauster 2, wherein: two air exhausters 2 are separately positioned in aiutage 3 passage of aiutage 3 leading section suction opeing 1 and rearward end exhaust outlet 7, be provided with at least double-filtration purification mesh screen 5 arranged in parallel vertically in aiutage passage, every grade of filtration, purification mesh screen 5 is all provided with changes end cap 6.Aiutage 3 is shaped with the hole being communicated with filter purification mesh screen 5 and the purification of conveniently opening changes end cap 6, and purification is changed inside end cap 6 and is accompanied with seal washer.Aiutage 3 is made with aluminum alloy materials.Front end suction opeing is trumpet type, and osculum one end connects firmly described aiutage oral area.Be welded outside two aiutage bracing frames 4 and described aiutage 3.In the three-stage filtration purification mesh screen that the present embodiment is arranged, be placed with active carbon bag in every grade of filtration, purification mesh screen, conveniently change active carbon bag, the handle that end cap 6 is fixedly connected with a handled easily is changed in each purification.Pernicious gas is drawn in aiutage 3 by leading section air exhauster 2, and the filtration, purification mesh screen through three ranks purifies, and extracts out, be discharged into flue by exhaust outlet 7 through rearward end air exhauster 2.The active carbon of purifying harmful gas can be reused, when active carbon in first class purification needs to change, change in first class purification by the active carbon in secondary purification, the active carbon in purifying three grades changes in secondary purification, adds new active carbon in three grades of purifications.Active carbon cost is low, replacing is convenient.Pernicious gas, by after extractor fan process, is not dispersed into and retouches paint room, be conducive to the healthy of operator.
Leading section air exhauster 2 is fixed on suction opeing place of aiutage Inner Front End portion, is drawn in aiutage by starting wherein said air exhauster 2 by the pernicious gas retouched in paint cover; First class purification, secondary purification, three grades of purification activated carbon bags are by the pernicious gas stage purification in aiutage; Rearward end air exhauster 2 is fixed on exhaust ports in aiutage, starts air exhauster 2 and purified gas is drawn through exhaust outlet is discharged into special flue.
