Description

A kind of negative-pressure air fan that can purify weldering cigarette
Technical field
It the utility model is related to a kind of negative-pressure air fan that can purify weldering cigarette.
Background technology
The negative-pressure air fan that the country generally uses at present, generally use electrically as power, with air quantity is big, consume energy small, cost The features such as low, the ventilation and air circulation cooling of ground power house are mainly used in, but there is no air cleaning unit generally. Welding technique can produce a large amount of weld fumes, pass through in operation as indispensable a kind of technique in modern industry Atmosphere pollution can be caused by not welding the negative-pressure air fan discharge factory building of fume purifying apparatus.
The content of the invention
The utility model overcome the deficiencies in the prior art, there is provided a kind of negative-pressure air fan that can purify weldering cigarette, main application Cool in the ground power house ventilation for having electric welding field and air circulation, while tobacco can be purified.
To achieve these goals, the utility model uses following technical scheme:A kind of negative pressure wind that can purify weldering cigarette Machine, including blower housing, motor, fan blade, power transmission shaft, the Blower Housing include air inlet and air outlet, and air inlet is set It is set to horn-like, Chain Link Fence is provided with air outlet;By being driven axis connection between motor and blade;Air inlet and motor it Between be provided with three-stage filtration purifying layer, the first order is stainless steel filter layer, and the second level is high polymer material filter layer, and the third level is lives Property charcoal adsorption layer.
The beneficial effects of the utility model are:
A kind of negative-pressure air fan that can purify weldering cigarette, is provided with three-stage filtration purifying layer, the first order between air inlet and motor For stainless steel filter layer, the second level is high polymer material filter layer, and the third level is activated carbon adsorption layer.This three-stage filtration net plays Filter the venomous injurant in tobacco and reduce the effect of the air pollution degree outside factory building.The utility model is simple in construction, easily In installation and operation.
Brief description of the drawings
The utility model is described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the principle schematic diagram of the utility model embodiment.
Label in figure:1st, blower housing;2nd, motor;3rd, fan blade;4th, power transmission shaft;5th, horn-like air inlet;6、 Fan outlet;7th, Chain Link Fence;8th, stainless steel filter layer;9th, high polymer material filter layer;10th, activated carbon adsorption layer.
Embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with accompanying drawing.
A kind of negative-pressure air fan that can purify weldering cigarette, including blower housing 1, motor 2, fan blade 3, the connection motor 2 and power transmission shaft 4, horn-like air inlet 5, fan outlet 6, the Chain Link Fence for being arranged on exit of fan blade 3 7th, stainless steel filter layer 8, high polymer material filter layer 9, activated carbon adsorption layer 10.
When the negative-pressure air fan is opened, the foul atmosphere containing weldering cigarette in factory building enters from horn-like air inlet 5 Negative-pressure air fan cavity, after then passing sequentially through stainless steel filter layer 8, high polymer material filter layer 9, activated carbon adsorption layer 10, weldering The purification efficiency of cigarette receiving dirt can reach 95%, and finally the pure air by purification is discharged to air by fan outlet 6 and worked as In.
It is to limitation of the present utility model that described above, which is not, and the utility model is also not limited to the example above, this technology Change that the technical staff in field makes in essential scope of the present utility model, remodeling, should also belong to guarantor of the present utility model Protect scope.
