Introduction of compressed air self-rescue device

The invention is mainly used for disaster relief and protection of coal mines with coal and gas outburst. The compressed air self-rescue device is installed in the copper room of the coal mine or at the proper position of the entrance of the ventilation roadway of the coal mining face or in the place where there are many people floating, as well as in the valve head, bottom hole, transportation and return air roadway, various station houses and other places. When roof caving, coal and gas outburst or prominent signs occur in the roadway, workers run into nearby places and places where coal respirators are installed to avoid disasters, put on respirators and wait for rescue. The box-type compressed air self-rescue device consists of an outer pipe system, a compressed air interface, an air inlet valve ali04, an air inlet connecting pipe, an air supply regulating device, a pneumatic pressure reducing valve, a drainage device and a mask. The model of bag-type compressed air self-rescue device is ZYJ, and the model of box-type compressed air self-rescue device is ZYJ-A. The invention consists of an outer pipe system, a compressed air interface, an air inlet valve, an air inlet connecting pipe and a mask. Two. Brief introduction of box-type compressed air self-rescue device ZYJ-A mine compressed air self-rescue device is aimed at the actual situation of coal dust, gas and carbon dioxide outburst in coal mines in China. Combined with the actual experience of respiratory rescue site, the box-type compressed air self-rescue device was innovated and developed into a new type of compressed air self-rescue device with practical invention. Because the box-type compressed air self-rescue device has a constant gas supply, a manual and stable high-pressure device and a device for discharging accumulated water, it is a very popular respiratory protector for miners. Second, the application place of box-type compressed air self-rescue device This device is mainly used for disaster relief protection in coal mines with coal and gas outburst. The box-type compressed air self-rescue device is installed in the proper position of the entrance of the mechanical air lane in the copper room or coal mining face in the underground coal mine, or in the place where there are many people floating, as well as the valve head, the bottom hole, the transportation return air lane, various station houses and other places. When roof caving, coal and gas outburst or prominent signs occur in the roadway, workers run into nearby places and places with respirators to avoid disasters and wear respirators to wait for rescue. Third, the structure of box-type compressed air self-rescue device ZYJ-A mine compressed air self-rescue device, built-in six breathing masks connected into a group, installed in a stainless steel box to form an underground self-rescue system, which is supplied by the ground pump room. (How many groups are installed in gas outburst mines depends on the size of the shaft and the number of underground workers. Under normal circumstances, the number of underground respirators shall not be less than one third of all underground personnel.
