Abstract

The invention relates to a device for solving the problem that smoke dust is unlikely to remove during the welding in a small space, in particular to a small-space dust absorption device for welding repair. The small-space dust absorption device is characterized by comprising an exhaust pipe connected with a connecting pipe which is sequentially connected with a rubber pipe and a compressed air valve. The small-space dust absorption device is unique in structure, positive and negative pressures are formed in an inner part of a cavity by compressed air, smoke dust inside the inner cavity is driven by the flowing compressed air to be discharged out of the cavity along the low-pressure direction of a pipeline, and thus an effect for clearing the smoke dust in the inner cavity can be realized.

Description

A kind of welding is reprocessed and is used the small space dust exhaust apparatus

Technical field

The present invention relates to a kind of device that small space position when welding flue dust is difficult for the removal problem that solves, especially relate to a kind of welding and reprocess and use the small space dust exhaust apparatus.

Background technology

In narrow and small cavity inner chamber welding process, can produce a large amount of weld fumes on every side, these flue dust can't be discharged in time, make after welding and have both affected personnel's operation, can produce injury to human body again.Cleaning for this type of flue dust adopts the band electric exhaustion fan to be extracted at present, if but narrow and small cavity bore hour can't be used the smoke evacuation of band electric exhaustion fan, can only eliminate by natural way, if things go on like this will have a strong impact on health, and also can affect welding efficiency.

Up to the present, also do not overcome the device of above-mentioned defect.

Summary of the invention

The objective of the invention is to overcome the defect of prior art, a kind of structure uniqueness is provided, utilizes compressed air to form positive/negative-pressure to cavity inner chamber position, in the situation that the flue dust of the mobile drive of compressed air cavity inner chamber is outside pipeline low pressure direction discharge side, thereby a kind of welding that reaches the effect that the flue dust of inner chamber is cleared up is reprocessed and is used the small space dust exhaust apparatus.

When energy solves the welding of small space position, flue dust is difficult for the problem of removal.

The present invention realizes in the following way:

A kind of welding is reprocessed and is used the small space dust exhaust apparatus, it is characterized in that: comprise exhaust tube, be connected with an adapter on exhaust tube, be connected with successively hose and compressed air valve in adapter;

Described exhaust tube is 30 ° ~ 60 ° with taking over two pipe axis angles, and in the nested described exhaust tube of described adapter, the degree of depth is 10 ~ 50mm.

The present invention has following effect:

1) structure uniqueness: device provided by the invention comprises exhaust tube, is connected with an adapter on exhaust tube, is connected with successively hose and compressed air valve in adapter; Described exhaust tube is 30 ° ~ 60 ° with taking over two pipe axis angles, and in the nested described exhaust tube of described adapter, the degree of depth is 10 ~ 50mm.

2) use easy to operate: device provided by the invention is put into cavity inside by dust exhaust apparatus integral body, will be placed in 80 ~ 200mm place, position to be welded apart from taking over a nearlyer end, and the other end is outside the mouth of pipe.Before welding, air pressure switch is opened, observed the air draft situation, after test weld is qualified, get final product normal operating.

3) the small space weld fumes is eliminated in time, reduces dust concentration, makes in the foundry goods welding process molten bath high-visible, and solder yield is by using front 50% to bring up to more than 80%.

4) this apparatus structure is simple, and cost of manufacture is low, and more common dust collection equipment is single saves several thousand yuan, and promotional value is higher.

The accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

The specific embodiment

A kind of welding is reprocessed and is used the small space dust exhaust apparatus, as shown in Figure 1: comprise exhaust tube 1, be connected with an adapter 2 on exhaust tube 1, take on 2 and be connected with successively hose 3 and compressed air valve 4;

Described exhaust tube 1 is 30 ° ~ 60 ° with taking over 2 liang of pipe axis angles, and the interior degree of depth of the nested described exhaust tube 1 of described adapter 2 is 10 ~ 50mm.
