AI Technical Summary

Technical Problem

The carbon dioxide absorber in the clean tank of the existing mining isolated compressed oxygen self-rescuer is prone to seep out, resulting in blockage of the doping hole and pressure reducing valve, affecting the oxygen supply, causing oxygen waste and insufficient oxygen supply.

Method used

The fixed sealing plate and the rotary sealing plate are provided on the shell of the cleaning tank. The rotary sealing plate and the ventilation ports of the fixed sealing plate are controlled to be misaligned or overlapped by the rotary air conduit, so as to achieve isolation and conduction of the cleaning tank, limit the flow rate, and avoid overflow of carbon dioxide absorbent.

Benefits of technology

Effectively prevent carbon dioxide absorber from overflowing and blocking the dosage hole and pressure reducing valve, ensure the stability of oxygen supply and quantitative oxygen supply, avoid oxygen waste, and extend the service life of the self-rescue device.

Abstract

A mining isolated compressed oxygen self-rescuer comprises a self-rescuer body, an oxygen bottle and a breathing assembly. According to the isolated compressed oxygen self-rescuer for the mine, the fixed sealing plate and the rotary sealing plate are arranged on the cleaning tank shell, the fixed sealing plate and the rotary sealing plate are both provided with air vents, the air guide pipe is matched with the rotary sealing plate, and the rotary sealing plate is driven to rotate by rotating the air guide pipe; a rotary sealing plate ventilation opening in the rotary sealing plate and a fixed sealing plate ventilation opening in the fixed sealing plate are controlled to be staggered and overlapped, so that the flow of the cleaning tank is limited by controlling the shell and the air bag to be isolated and communicated, and the cleaning tank is controlled to be opened and closed in good time; and the carbon dioxide absorbent is prevented from overflowing from the cleaning tank to block the quantitative hole and the pressure reducing valve.
