Detailed description of the invention
As shown in Figure 1, the present invention is provided with: air-intake device and air exhausting device, wherein, air-intake device comprises: explosion-proof air intake air filtering core device 7, air inlet fan 3 and blast pipe 5, explosion-proof air intake air filtering core device 7, air inlet fan 3 are connected successively with blast pipe 5, and wherein, explosion-proof air intake air filtering core device 7 adopts pipeline to be connected with between air inlet fan 3, and explosion-proof air intake air filtering core device 7 is placed in the outside of electric welding canopy 4, for inhale fresh air.Air due to import must be obtain in the safety zone of incombustible gas, so connecting pipe need be arranged on longer-distance safety zone between explosion-proof air intake air filtering core device and air inlet fan; Air inlet fan 3 adopts axial flow blower SF type or ventilating fan FA type usually, also can select explosion-proof type blower fan; Blast pipe 5 is installed on the inside of electric welding canopy 4, and blast pipe 5 adopts has plasticity flexible pipe, makes mouth of pipe direction adjustable, thus fresh air is floated equably in whole electric welding canopy 4.
Air exhausting device comprises: discharge pipe 6, blowing machine 2, water spray adsorbent equipment 10 and explosion-proof air-out air filtering core device 8, and discharge pipe 6, blowing machine 2, water spray adsorbent equipment 10 are connected successively with explosion-proof air-out air filtering core device 8, and discharge pipe 6 is installed on the inside of electric welding canopy 4; Discharge pipe 6 adopts has plasticity flexible pipe, makes mouth of pipe direction adjustable, thus guides poisonous and harmful flue dust 9 to the drift of discharge pipe 6 entrance, reduces the concentration of the poisonous and harmful flue dust 9 in electric welding canopy 4; Blowing machine 2 adopts axial flow blower SF type or ventilating fan FA type usually, also can select explosion-proof type blower fan; Water spray adsorbent equipment 10 can adsorb and reclaims poisonous and harmful flue dust 9, to keep the clean of air in electric welding canopy 4; Explosion-proof air-out air filtering core device 8 is placed in the outside of electric welding canopy 4, for filtering poisonous and harmful flue dust 9 gas be discharged.
Because electric welding canopy 4 is interim canopies, be difficult to accomplish to seal completely, so must be malleation in interim electric welding canopy 4, to ensure that the fuel gas outside electric welding canopy can not enter in electric welding canopy 4, this just needs intake slightly larger than exhaust air rate.
During use, the present invention is arranged on the scaffold being positioned at electric welding canopy 4 top, from the maximum local sucking-off flue dust of poisonous and harmful flue dust 9 concentration, to make flue dust more easily be eliminated.This is because: a large amount of poisonous and harmful flue dust 9 that can produce in electric welding field and oxyacetylene torch cutting operation process, due to poisonous and harmful flue dust 9 proportion lta, so, can drift about to electric welding canopy 4 top.
Lighting 1 is installed, by demand for providing illumination in scaffold and electric welding canopy 4 in electric welding canopy 4.Lampshade can turn an angle with vertical direction in the horizontal direction, that is: can do to rotate adjustment around horizontal axis line and vertical central lines, guarantee the visibility of operating position.
Lighting, blowing machine, air inlet fan, air filtering core device, water spray adsorbent equipment is prior art or adopts prior art manufacture.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
