Problems solved by technology

At present, our country has not yet entered the experimental stage. The main reason is that the mine conditions in foreign countries are very different from those in China, and it cannot be directly applied to mines in China.
[0003] With the frequent occurrence of mine accidents in our country, our country has also begun to pay attention to the development of emergency shelters in mines-rescue cabins, which do not have a compressed air system

Embodiment 1

[0019] A compressed air system for an underground shelter, which consists of: a main cabin 1, the main cabin is connected to a transition cabin 2, and a manual ball valve 9 and a one-way valve communicating with the transition cabin are installed on the inlet pipeline of the main cabin 12. The air intake pipeline 7 connected to the main cabin in the transition cabin is equipped with a precision pressure regulating valve 6, a high-performance air filter 5 and a pressure reducing valve 8. The transition cabin A manual shut-off valve 3 and a pair of one-way shut-off valves 4 are installed on the hatch upper side.

[0020] In the compressed air system of the underground refuge, the connection between the main cabin 1 and the transition cabin 2 is equipped with a manual shut-off valve 11, and the manual shut-off valve 11 and the second pair of one-way valves 12 are respectively placed On the upper side of the hatch of the main cabin.

Embodiment 2

[0023] According to the compressed air system of the underground shelter described in Example 1, the manual ball valve 3 is connected to the high-performance air filter 5 with a pipe 13, and the lower part of the high-performance air filter 5 is connected to the row Air hose 14, described high-performance air filter has one group. When the pressure in the main compartment is too high, a part of the gas in the main compartment is discharged to the transition compartment by the one-way stop valve; similarly, when the pressure in the transition compartment is too high, the gas in the transition compartment is discharged by the one-way stop valve Expelled overboard. The necessary condition to satisfy the work of the one-way stop valve is that the pressure difference of each connecting compartment is 0.2. This ensures that the cabin is always under positive pressure.

[0024] After the outdoor air enters the air pipe through the manual ball valve, the air is purified by the filte...

Abstract

The invention relates to a compressed air system of an underground shelter. A mine emergency shelter which is arranged and used in an underground mine is taken as an important measure for mine emergency rescue, and many experiences of successful rescue have already been obtained. The compressed air system of the underground shelter comprises a main cabin (1), wherein the main cabin is connected with a transitional cabin (2); a manual ball valve (9) and a one-way valve (12) communicated with the transitional cabin are arranged on the air inlet pipeline of the main cabin; a precise pressure regulating valve (6), a high-performance air filter (5) and a pressure reducing valve (8) are arranged on the air inlet pipeline (7) connected with the main cabin in the transitional cabin; and a manual stop valve (3) and a pair of one-way stop valves (4) are arranged at the upper side of the cabin door of the transitional cabin. The system of the invention is used for supplying air for life saving in mine accidents.

Description

Technical field: [0001] The invention relates to a compressed air system on an underground refuge, in particular to a compressed air system for an underground refuge. Background technique: [0002] Setting up and using mine emergency shelters in underground mines is an important measure in mine emergency rescue, and there have been many successful rescue experiences. For this reason, some countries with developed mining industry have done a lot of research on emergency shelters and rescue cabins. At present, our country has not yet entered the experimental stage. The main reason is that the mine conditions in foreign countries are very different from those in China, and it cannot be directly applied to mines in China. [0003] Along with mine disaster accidents occur from time to time in my country, my country has also begun to pay attention to the development of mine emergency shelter-rescue cabin at present, and this rescue cabin does not have compressed air system. Inv...
