Embodiment
The utility model provides a kind of welding shop, and the welding shop includes plant building 10, to the plant building The supply air system 11 of 10 conveying pure airs and the air return system 12 from the plant building 10 discharge flue dust, the supply air system 11 include including the ajutage 13 in the pure air feeding plant building 10, the air return system 12 by the car Between the aspiration channel 4 that siphons away of air in factory building 10, the mouth of pipe of the ajutage 13 is located at the bottom of the plant building 10, described The mouth of pipe of aspiration channel 4 is located at the top of the plant building 10.
With reference to the structure shown in figure 1, the welding shop provided using the application, supply air system 11 can send pure air To plant building, because the position of the mouth of pipe of ajutage 13 is located at the bottom of plant building, the fresh air being passed through can be in car Between the ground (welding carry out workspace) of factory building 10 form air layer, and hot-air dirty caused by welding can be due to buoyancy And rise, and constantly volume inhales the air of surrounding, fresh air above the ground slowly moves up, and passes through air return system 12 Aspiration channel 4 is sucked away.The dirty hot-air on the ground of plant building 10 constantly can be substituted by follow-up fresh air, so as to It can ensure that the ground of plant building 10 is in the air ambient of a cleaning, effectively increase the air quality of workspace.
Because the position that aspiration channel 4 is set is higher, the suction of aspiration channel 4 does not interfere with the work on the ground of plant building 10 Make the welding protection gas in area;And the purpose for the pure air that ajutage 13 is sent out is by the foul atmosphere on the ground of plant building 10 Drive upwards, thus ajutage 13 send out pure air can select slower flow velocity so that will not welding quality cause Detrimental effect.
Aspiration channel 4 and ajutage 13 can select appropriate height, it is preferable that the mouth of pipe of the ajutage 13 is away from described The ground 0-2m of plant building 10, ground 8-10m of the mouth of pipe of the aspiration channel 4 away from the plant building 10.From above-mentioned height Angle value so that it is fresh that the fresh air layer that the air that the mouth of pipe of ajutage 13 is sent out is formed can make staff be fully located at this In air layer, while cause the mouth of pipe suction of aspiration channel 4 to have a certain distance apart from welding job area, do not interfere with the guarantor of welding Protect gas.
In order that the air that supply air system is sent into does not influence the quality of welding, it is preferable that the supply air system 11 is to described The wind speed of the pure air of conveying is 0.1-0.5m/s in plant building 10, to cause the air velocity of supply air system feeding It will not blow away or take away the protective gas of welding;In addition, the temperature of the pure air is less than in the plant building 10 Room temperature, so that the pure air being sent into can sink, maintain the stable formation of fresh air layer.
The air return system 12 that the application provides can use appropriate structure, it is preferable that the air return system 12 includes taking out Suction pipe part, the clarifier 1 for purifying weld fumes and the blower fan 2 for providing suction force, the suction pipe fitting include mother Pipe 3 and the multiple aspiration channels 4 being arranged in the main pipe 3, the entrance and exit of the clarifier 1 connect the wind respectively Machine 2 and the main pipe 3, wherein, the caliber of the main pipe 3 reduces along the direction away from the clarifier 1.
As shown in Fig. 2 the suction force that blower fan 2 provides causes the air in plant building 10 to enter by the mouth of pipe of aspiration channel 4 Enter to aspirate the main pipe 3 of pipe fitting and moved to one end for being provided with blower fan 2 of main pipe 3, the air being sucked reaches meeting before blower fan 2 First it is cleaned device 1 to purify, cleaned air is discharged to the external world eventually through blower fan 2, so as to avoid the dirt to external environment Dye.In addition, the caliber of main pipe 3 reduces along the direction away from the clarifier 1, so as to keep the suction of 3 each position of main pipe The suction effect of airduct 4 is roughly the same so that each position obtains identical clean-up effect in plant building 10.
Preferably, the main pipe 3 includes the pipeline section for the different tube diameters being sequentially connected, and each pipeline section has constant caliber. As shown in Fig. 2 main pipe 3 includes the first pipe 5, second pipe 6 in stage casing and the 3rd pipe 7 of near-end of distal end, these three pipeline sections by In with constant caliber, main pipe 3 can be spliced into a manner of directly by welding, method is simply convenient to carry out.
Also it may be preferred that the caliber of the two neighboring pipeline section, which becomes, turns to 50-100mm.In the application, the first pipe 5 it is straight Footpath is 250mm, a diameter of 300mm of the second pipe 6, a diameter of 400mm of the 3rd pipe 7, and the diameter of aspiration channel 4 can be selected 160mm。
In order that aspiration channel 4 has preferable suction effect, it is preferable that the end of the aspiration channel 4 is provided with suspended hood 8, the cover body of the suspended hood 8 is downwardly and outwardly expanded.As shown in Fig. 2 the cover body that is downward and extending out of suspended hood 8 can be effective The air of ground draw ambient, improve the aspiration ranges of single aspiration channel 4.Preferably, the suspended hood 8 forms cross section as circle Horn-like structure, aspiration channel 4 can form the fan-shaped air suction areas that extend out along the cover of horn-like suspended hood 8, enter One step improves the suction effect of aspiration channel 4.
Preferably, the aspiration channel 4 includes the end aspiration channel for being arranged on the end of the main pipe 3.It is as shown in Fig. 2 female The distalmost end of pipe 3 is connected with end aspiration channel so that main pipe 3 forms the structure of insertion, improves the pumping efficiency of blower fan 2.
In order to adjust the suction position of aspiration channel 4, it is preferable that the end of the aspiration channel 4 is provided with flexible duct, described Suspended hood 8 is arranged on the end of the flexible duct, such as when the welding region in plant building 10 concentrates on a position, The suspended hood 8 of aspiration channel 4 can be directed at by the welding region with pivoting flexible pipeline, focused on dirty caused by the welding region Turbid air.
The clarifier of the application can select appropriate structure, it is preferable that the clarifier 1 includes entrance, outlet, close Fore filter that the entrance is set, the filter screen set close to the outlet and it is arranged on the fore filter and described Electrostatic filter device between filter screen.The air that fore filter can aspirate blower fan 2 is tentatively filtered, then using quiet Electric filter device carries out electro static filtering to preliminary filtered air, final to recycle filter screen to carry out most the air after electro static filtering Filtering eventually so that be discharged into the air in the external world by fully filtering, reach the standard of discharge.
Preferred embodiment of the present utility model, still, the utility model and unlimited is described in detail above in association with accompanying drawing In this.In range of the technology design of the present utility model, a variety of simple variants can be carried out to the technical solution of the utility model, It is combined in any suitable manner including each particular technique feature.In order to avoid unnecessary repetition, the utility model Various combinations of possible ways are no longer separately illustrated.But these simple variants and combination should equally be considered as the utility model institute Disclosure, belong to the scope of protection of the utility model.
