Mine pressure self-rescue device (Coal Safety Certificate No.:) is mainly used for underground disaster relief and protection in coal mines. When an accident occurs underground in a coal mine or harmful gases appear and workers cannot breathe normally, workers can enter the compressed air self-rescue device nearby to avoid disasters. The fresh air delivered by the mine compressed air self-rescue device enables disaster evacuees to breathe for a long time. Relaxed to achieve the purpose of safely avoiding disasters and stabilizing work mood. Under normal circumstances, the number of mine pressure air self-rescue devices installed underground shall not be less than one-third of all underground personnel. The mine pressure air self-rescue device has the functions of decompressing, silencing, flow adjustment, and filtering oil and water of the pressure air gas. It has the characteristics of easy installation, beautiful appearance, long service life, low noise, fresh and hygienic air, etc.
: > The structure of the mine pressure air self-rescue device
The mine pressure air self-rescue device is a new type of isolated gas respiratory protection device. This device comes in six groups in a box (groups can be designed according to requirements), and can be used by six people at the same time. To achieve the effect of taking care of each other.
The mine pressure air self-rescue device consists of a box, a mounting plate, an air inlet pipe, a door lock, a respirator (multiple sets), etc. The box body, mounting plate and air inlet pipe are made of stainless steel. The respirator is installed in the box and consists of a regulating valve, a pressure reducing filter valve, a spring hose, a self-priming filter mask, etc. The pressure reducing filter valve filters impurities, water and oil in the air, reduces pressure air noise, and can accurately adjust and control the air supply pressure so that workers can breathe unimpeded, smooth and comfortable.
: >Working principle of the mine pressure air self-rescue device
The mine pressure air self-rescue device uses a self-priming filter mask to be worn directly on the mouth for breathing, and is connected through a spring hose, which does not affect the user's sight. The spring The hose can be freely expanded and contracted, and the user can move freely within the expandable range of the spring hose.
The air supply to the mine pressure air self-rescue device generally adopts the mine pressure air pipeline.
