Description
Technical field
The present invention relates to a kind of mining survival capsule, be specifically related to a kind of transfer chamber of mining survival capsule.
Background technology
Incident mining accident takes place frequently in the coal production process, and cause a tremendous loss of lives is the safety problem that perplexs coal industry in recent years always.Owing to coal mining accident exists that destructive power is big, reason is complicated and is prone to cause characteristics such as Secondary cases accident, make mine disaster that the external world, back take place and in time to launch rescue.So in the mine underground work face place possess resistance to compression, gas defence, waterproof, heat insulation and can provide the escape capsule of essential life condition to be very important.Mining survival capsule is a kind of for after mine has an accident. the safe confined space that the miner that can't in time withdraw provides; Externally can resist blast impulse, high-temperature flue gas; Isolated toxic and harmful; Internally can remove toxic and harmful, win long life span for stranded miner provides oxygen, food and water.Simultaneously, trapped personnel can also be through communication monitoring equipment in the cabin, the extraneous rescue of guiding.Therefore, all drop into a large amount of man power and materials both at home and abroad mining survival capsule is used development.
Mining survival capsule can be divided into fixed and portable two types.Owing to portable survival capsule can move along with the transition of operation place, can change decorating position as required, have convenient, flexible characteristics, so use extensive day by day.Fixed or portable mining survival capsule all is made up of transfer chamber, existence cabin basically.The compressed air bottle group is being put in the transfer chamber the inside, supplies the hedging personnel to blow down the health pollutant and provide existence necessary oxygen.Transfer chamber is that the hedging personnel remove the important cabin body that the health pollutant gets into the existence cabin; But because the transition hatch door of present mining survival capsule is not provided with the device that effectively stops extraneous poisonous and harmful substance, pollutant is prone to get into transfer chamber and existence cabin with opening of hatch door.The removing of health pollutant does not simultaneously have good method yet, and artificial checkout time is longer, does not clean up, and has influenced hedging personnel's escape to a certain extent, also might bring pollutant into the existence cabin, thereby it is healthy to influence personnel.If remove the pressure rises that hedging personnel health pollutant must cause transfer chamber, must in time discharge out of my cabin, manually exhaust plant, very inconvenience with pressure-air.Mining survival capsule is a seal; Can protect the hedging personnel not receive the injury of extraneous toxic and harmful; But the hedging personnel want deliver from vault to save oneself in the cabin, must know whether extraneous environment allows deliver from vault, and extraneous temperature and toxic gas what will know at least.At present, the testing staff is the sampling of handheld device deliver from vault, and at this moment, toxic gas causes the injury that can not estimate to personnel in testing staff and the cabin probably in the moment of opening the door.In a word, existing survival capsule exists the not high problem of security performance.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can effectively stop environmental contaminants, and the health pollutant is removed the transfer chamber of the mining survival capsule effective, that the security protection performance is high simultaneously.
For solving the problems of the technologies described above; The technical scheme that transfer chamber adopted of mining survival capsule of the present invention is: comprise the compressed air bottle in the transfer chamber; This compressed air bottle is connected with the blowing pipe that is arranged in the transfer chamber top, and several air nozzles are installed on the blowing pipe; Compressed air bottle also is connected with the air curtain tube that is located at around the transfer chamber doorframe inner side edge through air inlet pipe; Installation and control valve on the air inlet pipe; Air curtain tube is provided with many little ventholes, and control valve is installed on the holder of doorframe outer side edges, its valve rod passes holder and be connected with elastic clip on the holder; The bulkhead of transfer chamber is provided with automatic control valve, and this automatic control valve is connected with pipeline, leans on the end in the cabin to be provided with ball in the automatic control valve body, and this ball contacts with the valve gap that is provided with through hole through spring, and valve gap is threaded with the other end of application valve body; The bulkhead of transfer chamber is provided with probe tube, and this probe tube is connected with valve, and suit elasticity is inhaled the appearance ball on the valve tube connector; The hatch door edge of transfer chamber is inlaid with rubber weather strip, and the periphery of rubber weather strip is inlayed the asbestos seal bar again.
The aperture of described venthole is towards outdoors, and the aperture face is not more than 45 ° with the angle of door vertical plane.
Hand-operated valve and pressure meter are installed on the described pipeline.
Technique scheme is installed the air curtain tube that is provided with many little ventholes around the doorframe inner side edge; When opening the transition hatch door, elastic clip is upspring, and places the pressure-air in the cabin to get into air curtain tube through control valve; And from many little ventholes, blow out; Thereby the formation air curtain stops that effectively extraneous hazardous contaminant gets in the cabin, has the good characteristics of security protection performance.The blowing pipe of several air nozzles is installed at the transfer chamber top; Therefore; When the hedging personnel get into transfer chamber, the high-pressure aerial fog of air nozzle ejection can be fast, effectively, hazardous contaminants such as dust on the purge health neatly, guarantee hedging personnel's safety.The present invention can effectively stop environmental contaminants, the health pollutant is removed effective simultaneously.The structure that adopts pipeline, valve, elasticity to inhale the appearance ball, as long as open valve, personnel must deliver from vault inhale a kind ball with elasticity and just can not obtain air sample out of my cabin in the cabin in, have protected effectively that the hedging personnel's is healthy.Adopted the automatic control valve that is made up of valve body, ball, spring and valve gap, regulated the pressure of spring, when cabin internal pressure during greater than pressure out of my cabin, automatic control valve is promptly opened exhaust.Inlay rubber weather strip at the hatch door edge, rubber weather strip has good sealing performance, inlay the asbestos seal bar again in the periphery of rubber weather strip simultaneously, and the asbestos seal bar has well heat-resisting, heat insulation and load performance.The present invention uses reliably, and the security protection performance is good.
