Problems solved by technology

[0003] (1) The temperature of the equipment is high;
[0004] (2) The heat dissipation performance of the oxygen-generating drug chamber is poor, and the chemical reaction heat in it is not easy to dissipate, which leads to the oxygen temperature at the mouthpiece plug being higher than the comfortable temperature range of the human body;
[0005] (3) The tightness of the airbag and the overall system is poor, which cannot meet the requirements for the airbag and the overall tightness under high standard conditions;
[0006] (4) The arrangement of cooling components and medicines is unreasonable, resulting in high breathing resistance and unsmooth breathing process

Abstract

The invention relates to an isolation type chemical oxygen self rescuer comprising a seal housing, a respiratory system, an oxygen candle, a drug tank and an airbag. The respiratory system and the oxygen candle are communicated with the top of the drug tank, the airbag is communicated with the bottom of the drug tank, and the respiratory system, the oxygen candle, the drug tank and the airbag are placed in an accommodating space of the seal housing. The self rescuer is a 45 min one, the drug capacity, the entire size and the size of the drug tank are researched comprehensively, so that the device is capable of meeting the requirements of 45 min respiratory capacity and time through the minimum size; aiming to improve the tightness performance of the device, the upper and lower cover sealing manner, airbag manufacturing process and connection process of various ventilation components are optimized, so that the tightness performance of the device is improved, and the safety is higher.

Description

technical field [0001] The invention relates to safety equipment for coal mines, in particular to an isolated chemical oxygen self-rescuer. Background technique [0002] The structure of a common chemical oxygen self-rescuer mainly includes a breathing assembly arranged in a single-layer shell, an airbag assembly, an oxygen candle, and an oxygen-generating medicine chamber with oxygen-generating tablets inside. The oxygen-generating medicine chamber and oxygen candle are located in the shell The lower part, and the bottom of the oxygen-generating medicine chamber and the oxygen candle in the shell is an air chamber, the air chamber communicates with the airbag assembly, and the breathing assembly communicates with the airbag assembly. When in use, the operator absorbs oxygen through the mouthpiece plug in the breathing assembly. During long-term use, it is found that this type of self-rescuer has the following disadvantages after working for a long time: [0003] (1) The te...
