One of its shortcoming is exactly that the potassium superoxide tablet filled in this self-rescuer has a slow oxygen release rate during the early and late stages of wearing and using, so that the oxygen supply is insufficient; Excess, causing a large amount of oxygen-enriched air to be wasted outside the airbag through the exhaust valve; resulting in shortened protection time, increased breathing resistance, and excessively high inhalation temperature.

Embodiment Construction
[0022] as attached Figure 4 As shown, when manufacturing, processing and assembling the isolated chemical oxygen self-rescuer for mines, while filling the oxygen generator tank with potassium superoxide tablets, several bags of calcium hydroxide are evenly mixed in the potassium superoxide The other assembly processes are consistent with those of various existing isolated chemical oxygen self-rescuers for mines.
[0023] And when the well-entering operator escapes in distress and wears and uses this novel self-rescuer, it is also consistent with the method steps of wearing and using the existing various mine-used isolation type chemical oxygen self-rescuers.

The invention relates to an oxygen release speed balance novel mining isolation type chemical oxygen self-rescuer. The oxygen release speed balance novel mining isolation type chemical oxygen self-rescuer has a series of advantages that oxygen generating tablet tanks of the novel self-rescuer are filled with potassium superoxide tablets, bagged calcium hydroxide is arranged in the potassium superoxide tablets in a mixed manner, accordingly, the oxygen release speeds are balanced and stable, the protection time can be prolonged, respiratory resistance can be reduced, the inspiration temperatures can be lowered, technologies for producing mining isolation type chemical oxygen rescuers in China can reach a new level, and the like.
Description
(1) Technical field [0001] The patent of the present invention relates to a new type of isolated chemical oxygen self-rescuer for mining with balanced oxygen release rate. (2) Background technology [0002] The isolated chemical oxygen self-rescuer is a mine-used personal self-rescuer that most coal mines in my country provide for the workers who enter the well to wear and use when escaping from distress. Compared with other types of self-rescuers, this self-rescuer has many advantages, but also has some disadvantages. One of its shortcoming is exactly that the potassium superoxide tablet filled in this self-rescuer has a slow oxygen release rate during the early and late stages of wearing and using, so that the oxygen supply is insufficient; Excess, causing a large amount of oxygen-enriched air to be wasted outside the airbag through the exhaust valve; resulting in shortened protection time, increased breathing resistance, and excessively high inhalation temperature and ma...
