Problems solved by technology

For a long time, this type of self-rescuer has had a problem that is not easy to solve, that is, if an oxygen cylinder with a water volume of 0.38L is used in this self-rescuer, its volume will be smaller, its quality will be lighter, and its price will be lower. It will be lower, and it is very popular among miners who enter the well. However, when doing factory inspection and type inspection, it is often because the amount of medical oxygen filled in the 0.38L oxygen cylinder is slightly less than a few liters, and the safety margin is higher than that of 0.4L. The oxygen cylinder of the self-rescuer is slightly smaller; if a 0.4L oxygen cylinder is used, although the safety margin is larger, it will increase the volume, weight and price of the self-rescuer due to the increase in the volume of the oxygen cylinder. unpopular with coal mine workers

Embodiment Construction

[0016] like figure 2 As shown, in the manufacture, processing and assembly of the new isolated compressed oxygen self-rescuer, on the premise that other assembly processes are consistent with the existing isolated compressed oxygen self-rescuer assembly process, two processes are added, one process is to put the oxygen candle Fastened on the lid above the clean tank, another process is to fill the clean tank with a sufficient amount of calcium hydroxide medicament, and then fill some appropriate amount of lithium hydroxide medicament.

[0017] And when the operator who enters the well is in distress and escapes and wears the novel isolated compressed oxygen self-rescuer, the operating procedure is to open and throw away the upper shell of the self-rescuer, start the starting device on the oxygen candle, and wait until the oxygen released by the oxygen candle makes the airbag When inflated, pull out the mouthpiece plug of the airbag breathing hose, clenched the mouthpiece toot...

Abstract

The invention relates to a novel mine isolating compressed oxygen self-rescuer with protection time being 45 min. On the premise of not changing the basic structure of an existing self-rescuer of the type, an appropriate amount of lithium hydroxide is added into a cleaning tank in the self-rescuer, a solid oxygen source called oxygen candle for short is arranged on the cleaning tank, and in this way, the production and manufacturing technology of the self-rescuer reaches the international advanced level. The novel self-rescuer can meet regulations and requirements of related standards and rules in china and actual requirements of the market and coal mine workers.

Description

(1) Technical field [0001] The patent of the present invention relates to a new type of isolated compressed oxygen self-rescuer for mining with a protection time of 45 minutes. (2) Background technology [0002] Mine compressed oxygen self-rescuer is a kind of personal respiratory protection equipment with scientific principle and mature manufacturing technology. When a sudden major disaster occurs in a coal mine, the surviving miners wear this type of self-rescuer in time, so that they can escape from danger, escape from the disaster area, and save their lives. This type of self-rescuer is currently implemented and implemented according to AQ1054——2008 "Isolated Compressed Oxygen Self-Rescuer", the safety production industry standard of the People's Republic of China. This standard stipulates several types of compressed oxygen self-rescuers with a protection time of 30min, 45min, 60min, 90min, and 120min; The actual use time required by the performance; it can be seen tha...
