Abstract
The utility model discloses a gas pumping self-save system and devices thereof, wherein, the gas pumping self-save device is composed of a pipeline part, a switch and a gas conveying part. The gas pumping self-save system is formed by a plurality of gas pumping self-save devices to form a set of self-save system. Every two gas pumping self-save devices are connected by a gas pumping pipe. The gas supply source of the self-save system can share the same pipeline with a mine gas pumping system. The utility model has the advantages of cost saving, convenient management, simple use method, reliability, flexibility, etc., and has the functions of reducing pressure, regulating flow, purifying and removing the noise and creating safe and comfortable refuge conditions for refuge people.
Description
The utility model is made up of calm the anger system of saving oneself and device, keeps away calamity for the miner and use in coal and gas outburst danger mine are arranged.
The outstanding danger of coal and gas is often arranged, the life security that directly threatens the miner under coal mine.The national routine Britain of many in the world main coal minings, Japan etc. all adopt fixed system of saving oneself and the device of calming the anger 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.At present, the isolated self-rescuer of domestic usefulness, AZL-40 type filtering type self-rescuer are not also developed fixed system of saving oneself and the device of calming the anger.
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 205 pairs of coal and gas outburst mine coal productions occupy sizable ratio.Along with the development of safety of coal mines technology, invent a kind of system and its apparatus of saving oneself, significant to ensureing miner's life security.The miner goes into the well and carries self-rescuer; Fixed system of saving oneself and the device of calming the anger of installing in the tunnel again, when mine generation coal and gas were given prominence to disaster, the miner can enter this device nearby and keep away calamity.This has just formed the more complete system of saving oneself.Reach the purpose of safety in production.
Structure of the present utility model and principle
One, the self-help apparatus of calming the anger
Calm the anger self-help apparatus (Fig. 1) partly by pipeline, switch, air feeding device is partly formed.Pipeline partly is made of threeway 1, air pipe 2, elbow 3, joint 4, air pipe 6.Air pipe 2 is to select different specification size with air pipe 6.Switch 5 is the ball valve straight-through structure.Air feeding device partly is made of air feeding device 7, protecting band 8, clamp 9.
Air feeding device (Fig. 2) is a critical component of the present utility model, is made up of valve head 10, valve rod 11, overcoat 12, interior cover 13, pad 14, valve tail 15, jam nut 16.Reduce pressure to calming the anger, Flow-rate adjustment realizes by valve head 10, valve rod 11.Decompression is that the compressed air with 0.3～0.7MPa reduces to below the 0.1MPa, and the Flow-rate adjustment of gas is to 2 times of the human body maximal breathing capacity, promptly 150～200 liters/minute.Purify air and eliminate noise and realize that by overcoat 12, interior cover 13 overcoat is with there being the poromerics of certain particle size to be made.Purify air promptly is that the dirt in the compressed air is sneaked in filtering in producing and carry the compressed air process.Eliminating noise is that the noise that produces in decompression process is reduced to about 20 decibels, is beneficial to keep away the stable of calamity miner mood.The air feeding device of this device is made best of copper material, but because its anticorrosion is difficult for getting rusty.
Two, the system of saving oneself of calming the anger
The design of the system of saving oneself of calming the anger is that the actual conditions according to mine carries out.At first should be 0.35～0.7MPa pressure at pressurized air source; Its air demand should be 1.3～1.5 times of air consumption (air consumption when being the disaster relief), and air consumption should be total air consumption of employed self-help apparatus in the mine and adds and start other total air consumption sums with wind devices during this period of time during the disaster relief.Air supply system can be separate payment, also can with the shared pipe-line system of down-hole voltage supply wind system.
Installing of the present utility model and use
The self-help apparatus of calming the anger 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.Form one group of system of saving oneself by three or five self-help apparatus of calming the anger (Fig. 1) and keep away calamity for three people or five people.A job site can be adorned one group or several groups, but the number of installing must be greater than this place staff's number.Often there is the place of flow of personnel also must install enough self-help apparatus.Respectively calm the anger between the self-help apparatus and to connect (Fig. 1) with air pipe 2 and link to each other with supply air line in the mine laneway with flexible pipe again.
When meeting the calamity use, keep away the calamity personnel switch 5(Fig. 1) handgrip open, the position of opening is that handgrip is consistent with the pipeline direction, creep in the protecting band rapidly then, the calming the anger after the decompression throttling in the pipeline of calming the anger forms positive draft to be higher than atmospheric pressure, and fresh air is full of protecting band, and the pernicious gas of outside can not enter protecting band, keeps away the calamity personnel and obtains rescue.Protecting band can be that plastics or rubber are made.
The utility model advantage:
This system of saving oneself can with the shared circuits of mine compressed-air system, not only cost saving and also be convenient to the management.
This device has the function of decompression, Flow-rate adjustment, purification, elimination noise, has created safe, the comfortable condition of taking refuge for keeping away the calamity personnel.Advantages such as using method is simple, reliable, flexible.
Claims (2)
1, the utility model is a kind of system and its apparatus of saving oneself of calming the anger, calm the anger self-help apparatus partly by pipeline, switch, supply gas and partly form, it is characterized in that pipeline partly is made of threeway, air pipe, elbow, joint, switch is the ball valve straight-through structure, supplies gas partly to be made of air feeding device, protecting band, clamp.The system of saving oneself of calming the anger forms one group of system of saving oneself by several self-help apparatus of calming the anger, respectively calm the anger between the self-help apparatus to connect with air pipe, the air feed of the system of saving oneself of calming the anger be separately or with the shared pipe-line system of down-hole voltage supply wind system.
2, a kind of system and its apparatus of saving oneself of calming the anger according to claim 1, the self-help apparatus that it is characterized in that the calming the anger air feeding device partly of supplying gas is made up of valve head, valve rod, overcoat, interior cover, pad, valve tail, jam nut.
