Description
Technical field
The invention belongs to the safety of coal mines apparatus field, relate to a kind of air self-help apparatus of the Novel pressure for colliery.
Background technology
The gas of all can gushing out under most of coal mine, once the gas containing finite concentration gas is met Mars, just may set off an explosion, and airborne oxygen concentration is sharply descended, or cause that other pernicious gases are gushed out suddenly, roof fall, the disaster such as cave in, the field operation personnel are injured.In this type of accident, many workmans breathe self-help apparatus and death by suffocation owing to lacking.Isolated type protection self-help apparatus is while under coal mine, above-mentioned disaster occurring, one of main hedging self-helping tool of personnel in the pit.
" the improving the notice of coal mine downhole safety hedging " six large systems " about construction " of Administration of Work Safety Supervision of country, the issue of national Supervisor Bureau of Coal points out: coal mining enterprise must require to set up on the basis of compressed-air system according to " safety regulations in coal mine ", the requirement of pressing the wind air feed can be provided during catastrophe according to all digging operations place, further build and improve compressed-air self-help system.But the existing compressed air self-help apparatus in each mining area is also mainly continued to use, to take the patent of Chongqing Inst., Academy of Coal Science, Ministry of Coal Industry in 1987 application be the compressed air self-help equipment that main models is produced, overlong time, and defect exposes and increases gradually, such as complicated operation, restriction personnel activity, be unfavorable for finding rapidly, application life is short, the smell of performance to human body deposit toxic action, install not attractive in appearance, do not meet the Modern Pit standardization and require, can not solve that communication problem, the noise of aboveground down-hole is excessive, weak effect etc. purifies air.
Summary of the invention
The present invention seeks in order to solve existing compressed air self-help apparatus complicated operation, restriction personnel activity, be unfavorable for finding rapidly, application life is short, the smell of performance to human body deposit toxic action, install not attractive in appearance, do not meet that the Modern Pit standardization requires, noise is excessive, the weak effect that purifies air, can not solve the problems such as communication of aboveground down-hole.
A kind of compressed-air self-rescue device used for coal mine, the outside of compressed air self-help apparatus is by triplate line, electromagnetic valve, LED alarm lamp, form with the cabinet door of electromagnetic lock, the casing that pastes high fluorescent bar.Wherein, triplate line is in the casing top, and two, its top pipeline is connected with supply air line respectively, and one of its underpart pipeline inserts casing from the casing center of top.Electromagnetic valve is arranged in the periphery of triplate line bottom pipeline, and next-door neighbour's casing.Top position, the outside of every fan cabinet door arranges a LED alarm lamp.The inside of compressed air self-help apparatus is comprised of case chamber and the oronasal mask of air feeding device, installation control panel.Air feeding device and oronasal mask are located in casing.Casing is hexahedron, and every forms with electromagnetic lock, the cabinet door that can open downwards by one, and separated by the dividing plate in casing.Air feeding device is comprised of air feeding device main body and the air pipe be connected on main body.The air feeding device main body is separated by the casing internal partition, and its center of top and triplate line lower nozzle are joined.Five of air feeding devices are comprised of the built-in case chamber with spirality appendix oronasal mask, and one side is comprised of the case chamber that control panel is installed.The air feeding device main body consists of the double-deck copper mesh shaped through the hot pressing of certain particle size copper powder, foam, thickness quartz sand alternating layers, porous plate, plenum chamber, collecting chamber and drainage switch.Wherein, double-deck copper mesh, foam, thickness quartz sand alternating layers, porous plate one, plenum chamber are successively arranged from inside to outside round the main shaft of air feeding device main body.Their below, be also the bottom of air feeding device main body, arranges successively from top to bottom porous plate two, collecting chamber.Drainage switch is located at the collecting chamber bottom by edge.When the compressed air of 0.3 ~ 0.7MPa from pressure ventilation pipe by the road, electromagnetic valve is while entering the air feeding device main body, first by electromagnetic valve, pressure wind is decompressed to below 0.1MPa, through double-deck copper mesh and the foam be sandwiched in therebetween, filter for the first time again, enter again the double-deck copper mesh of the second layer and thickness quartz sand alternating layers and carry out filtering for the second time and de-noising, then filter for the third time through porous plate, breathe for keeping away the calamity personnel by the flexible spirality appendix of tool inlet port nose cup.Steam unnecessary in air collects the inflow collecting chamber through porous plate, on ordinary days can open drainage switch and discharge ponding.When pernicious gas occurs in down-hole, prominently gush, roof fall, cave in, during the accident such as blast, control panel is accepted early warning signal, buzzer and LED alarm lamp automatic alarm, cabinet door is opened automatically, blast is regulated automatically, relends and helps high fluorescent bar, and the personnel in the pit can carry out and save oneself efficiently rapidly.By the compressed-air self-help system of networking, ground control centre and personnel in the pit can rake in and contact, thereby arrange rescue work better.
The present invention has following features: disaster easily finds while occurring, and has better decompression, Flow-rate adjustment, purification, removes the function of making an uproar, and using method is simple; Adopt the oronasal mask air feed, make personnel be easy to observe the condition of a disaster; Five oronasal mask share a set of blower, and cost is low, and the compressed air utilization rate is high, easy to utilize, also meet one group of down-hole five people's training custom; Install attractive in appearancely, meet the requirement of modern mine standardized set reduction; Can realize networking communication and the warning function of down-hole hedging; Air feeding device corrosion-resistant being difficult for gets rusty.
