Abstract
The utility model relates to a pressure wind self-rescuer, which comprises a pipeline, a switch, an air feeder, an oral-nasal mask, a box body and the like. The air feeder and the oral-nasal mask are both arranged in the box body, and the plurality of oral-nasal masks share one set of air feeder to be used by a plurality of disaster-avoiding personnel at the same time, so that the manufacturing cost is low, and the utilization rate of compressed air is high.
The self-rescuer not only has the functions of pressure reduction, flow regulation, purification and noise elimination, but also creates the advantages of complete refuge conditions for disaster-avoiding personnel and the like. Moreover, the structure is more reasonable, and the disaster prevention personnel can observe the disaster at any time by adopting the air supply of the mouth-nose mask, so as to be beneficial to taking measures. The use is convenient, simple, reliable and flexible.
Description
The utility model is a kind of compressed air self-help device.Keeping away calamity for the miner in coal and gas outburst danger mine are arranged uses.
The outstanding danger of coal and gas is often arranged, the life security that directly threatens the miner under coal mine.Rich coal resources in China, various places coal-forming environment and geological conditions differ greatly, and the different coal gas bearing capacity is also different, and existing 20
The coal and gas outburst mine coal production is occupied sizable ratio.At present, many in the world main coal minings national for example Britain, Japan etc. all adopt fixed compressed air self-help system and device in the mine that coal and gas outburst danger are arranged, but price is expensive, and the characteristics in incompatibility China's coal-mine tunnel.The isolated self-rescuer of domestic usefulness, AZL-40 type filtering type self-rescuer.Chongqing Branch, Coal Science Research General Inst was developed the system and its apparatus of saving oneself of calming the anger before more than 2 years, and Patent Office of the People's Republic of China authorizes utility model patent, its patent No. 87214112.8 on August 10th, 1988.After using, remain in weak point, higher as cost, keep away calamity personnel inconvenience in protecting band and observe outside the condition of a disaster etc.
The purpose of this utility model is exactly in order to adapt to the development of China's coal-mine safe practice, and the fixed system and its apparatus of saving oneself of calming the anger of inventing and be installed in the down-hole is improved, and makes it to become more perfect self-rescuer.When the outstanding disaster of mine generation coal and gas, the miner can use this self-rescuer to keep away calamity nearby, and is significant to ensureing miner's life security.
Structure of the present utility model and principle
Compressed air self-help device (Fig. 1) is made up of pipeline 1, switch 2, air feeding device 3, oronasal mask (or pocket) 4, casing 5.Wherein air feeding device and oronasal mask are critical components.Air feeding device 3 and oronasal mask 4 all are contained in the casing 5.
Air feeding device 3(Fig. 2) forms by valve head 6, valve rod 7, overcoat 8, interior cover 9, seal washer 10, valve tail 11, locking nut 12, air chamber 13.Air chamber 13 is the garden tubular construction, and there are several ports of giving vent to anger on surface, outer garden.The port of giving vent to anger is connected with the corrugated tube of an oronasal mask.Be the shared cover air feeding devices of a plurality of oronasal mask.
Oronasal mask 4(Fig. 3) forms by corrugated tube 14, body 15, exhaust check valve 16.
Operation principle: when the compressed air of 0.3～0.7MPa by the road 1, switch 2 enters air feeding device 3, it is following and carry out filtering through overcoat 8 and eliminate noise and enter air chamber 13 that 7 pairs of valve head 6 in the air feeding device 3 and valve rods press wind to reduce pressure to make it pressure to reduce to 0.1MPa, breathe for keeping away the calamity personnel through the body 15 of flexible, telescopic corrugated tube 14 inlet port nose cups 4, unnecessary gas and waste gas are discharged through exhaust check valve 16 again.What of its air demand are relative distance between valve rod 7 and the valve head can regulate.The size of wind supply quantity is by the quantity Z decision that is contained in oronasal mask on the air chamber 13, and wind supply quantity should be 150～200 liters/minute * Z.Overcoat 8 is the micropore garden covers that processed shape by the copper powder hot pressing that certain particle size is arranged.Oil in the compressed air, water and other impurity are filtered through micropore and remove, and purify; The noise that produces in throttling step-down process can also be reduced to simultaneously and be beneficial to keep away the stable of calamity personnel mood about 80 decibels.
The effect of the exhaust check valve 16 in the oronasal mask (or pocket) 4 is the air unnecessary in the outlet nose cup 4 and the waste gas of exhalation.Oronasal mask 4 internal gas pressures sharply descend when air-breathing, thereby exhaust check valve 16 is closed rapidly and prevented in the pernicious gas inlet port nose cup 4.
Installing of the present utility model and use
The compressed air self-help device can be installed in the mine laneway or chamber in, also can be installed in the working face or in the heading end, that is to say and allly all can install in the place that has the people to work.Each self-rescuer can be adorned several oronasal mask, uses for many people disaster relief.One or several compressed air self-help device can be installed in a job site, and the sum of oronasal mask must be greater than staff's number of this job site.Often enough self-rescuers can be installed in the someone job site of flowing.This self-rescuer is connected with air supply pipe with threeway.
Meet calamity when using, keep away the calamity personnel and the handgrip of switch 2 (Fig. 1) is upwards pulled made itself and horizontal vertical, case lid just automatically springs open, and connects and press wind regime, and conveying end nose cup 4 is breathed rapidly.The material of oronasal mask 4 should rubber be good, also available other materials.
Must check earlier when the staff advances class that the reliability of compressed air self-help device can carry out Job Operations, mainly check handgrip whether flexibly, whether ventilation connect with ponding, the oronasal mask of getting rid of in the pipeline 4, has or not damage etc.
The utility model advantage:
After improving, this self-rescuer removes has the function of decompression, Flow-rate adjustment, purification, elimination noise, has created the safe condition of taking refuge for keeping away the calamity personnel.Outside the advantages such as using method is simple, reliable, flexible, also have following advantage:
1, structure is more reasonable, adopts the oronasal mask air feed.Keep away the calamity personnel and can observe the condition of a disaster at any time, in order to taking measures.
2, by the shared cover air feeding device of a plurality of oronasal mask, not only cheap; And compressed-air actuated utilization rate height, easy to utilize.
Claims (2)
1, the utility model is a kind of compressed air self-help device, it is characterized in that the compressed air self-help device partly is made up of pipeline, switch, air feeding device, oronasal mask, casing etc.Air feeding device and oronasal mask all are contained in the casing.
