Abstract
The utility model discloses a low noise air curtain and blow washing device of a mine-used lifesaving cabin. The low noise air curtain and blow washing device of the mine-used lifesaving cabin comprises an air compressing bottle inside a transitional cabin. The air compressing bottle is connected with a blow washing pipe on the top of the transitional cabinet through a pipeline, and the blow washing pipe is provided with a plurality of air sprayers. The pipeline is further connected with an air curtain pipe on the edge of a transitional cabinet door, and a silencer is installed on the pipeline between an outlet of the air compressing bottle and a connector of the blow washing pipe. According to the low noise air curtain and blow washing device of the mine-used lifesaving cabin, noise is reduced from 90 decibels in the prior art down to 69 decibels, environment is obviously improved, and fitness of people is benefited.
Description
Technical field
The utility model relates to a kind of mine escape capsule, is specifically related to low noise air air curtain and bubbling device in a kind of mine escape capsule transfer chamber.
Background technology
Incident mining Frequent Accidents in coal production process, cause a tremendous loss of lives is the safety problem that perplexs in recent years coal industry always.Because coal mining accident exists that destructive power is large, reason is complicated and easily causes the characteristics such as Secondary cases accident, make mine disaster occur after the external world can't in time launch rescue.So place in the mine down-hole scope of operation possess resistance to compression, gas defence, waterproof, heat insulation and can provide the escape capsule of essential life condition to be very important.Mine escape capsule is the security closed space that a kind of miner that can't in time withdraw after having an accident for mine provides, externally can resist blast impulse, high-temperature flue gas, isolated toxic and harmful, internally can provide oxygen, food and water for stranded miner, remove toxic and harmful, win long life span.Simultaneously, trapped personnel can also be by Communication Monitoring equipment in the cabin, the extraneous rescue of guiding.
Mine escape capsule all is comprised of transfer chamber, survival cabin and equipment compartment basically.The compressed air bottle group is being put in the transfer chamber the inside, and be connected with the air curtain tube that is arranged in transition hatch door edge and the blowing pipe at top, air nozzle is installed on blowing pipe, the necessary oxygen of surviving for the hedging personnel is provided on the one hand, the air curtain that forms of pressure-air on the other hand, stop that effectively extraneous hazardous contaminant enters in the cabin, the high-pressure aerial fog of blowing pipe ejection can be fast, effectively, hazardous contaminants such as dust on the purge health neatly, guarantee hedging personnel's safety.The noise that produces when spraying due to pressure-air reaches more than 90 decibels, and is irksome and be detrimental to health.
Summary of the invention
Technical problem to be solved in the utility model is to provide low noise air air curtain and the bubbling device in a kind of mine escape capsule transfer chamber of environmental protection.
For solving the problems of the technologies described above, the low noise air air curtain of mine escape capsule of the present utility model and the technical scheme that bubbling device adopts are: comprise the compressed air bottle in transfer chamber, compressed air bottle is connected with the blowing pipe at transfer chamber top by pipeline, several air nozzles are installed on blowing pipe, pipeline also is connected with the air curtain tube at transition hatch door edge, on the pipeline between the interface of the outlet of compressed air bottle and blowing pipe, noise damper is installed.
Technique scheme is being installed noise damper on the pipeline between the interface of the outlet of compressed air bottle and blowing pipe, noise is down to below 69 decibels from original 90 decibels, therefore, has obviously improved environment, is conducive to the healthy of hedging personnel.
Description of drawings
Accompanying drawing is the utility model mining low noise air air curtain and bubbling device structural representation.
The specific embodiment
By accompanying drawing as seen, the low noise air air curtain of mine escape capsule of the present utility model and bubbling device comprise that transfer chamber 1, compressed air bottle 2 are placed in transfer chamber 1, compressed air bottle 2 is connected with the blowing pipe 4 at transfer chamber top by pipeline 3, and several air nozzles 5 are installed on blowing pipe 4; Pipeline 3 also is connected with the air curtain tube 6 at transition hatch door edge, on the pipeline 3 between the interface of the outlet of compressed air bottle 2 and blowing pipe 4, noise damper 7 is installed.
Claims (1)
1. low noise air air curtain and the bubbling device of a mine escape capsule, comprise the compressed air bottle in transfer chamber, compressed air bottle is connected with the blowing pipe at transfer chamber top by pipeline, several air nozzles are installed on blowing pipe, pipeline also is connected with the air curtain tube at transition hatch door edge, it is characterized in that: the upper noise damper (7) of installing of the pipeline (3) between the interface of the outlet of described compressed air bottle (2) and blowing pipe (4).
