Automatic air quantity controller

Abstract

The invention discloses an automatic air quantity controller, which comprises a main air barrel and branch air barrels, wherein the side surface of the main air barrel is connected with the branch air barrels; a transmission shaft I passes through the main air barrel; two ends of the transmission shaft I are arranged on the main air barrel through bearings; a transmission shaft II passes through the branch air barrels; two ends of the transmission shaft II are arranged on the branch air barrels through bearings; the transmission shaft I and the transmission shaft II are engaged with each other through fan teeth; a main fan blade is arranged on the transmission shaft I; a branch fan blade is arranged on the transmission shaft II; and the other end of the transmission shaft II is provided with a switch seat. By the automatic air quantity controller, the working efficiency of a first-aid team during discharging of gas is improved, the automation level is increased, the gas can be discharged more scientifically and rescuers is safer, the economic benefit of mines is improved and safety and reliability are realized.

Description

technical field [0001] The invention relates to an air volume controller for mine rescue team to discharge gas, in particular to an automatic air volume controller. Background technique [0002] In recent years, the country has invested more and more in safety, and has paid more and more attention to safety. The rescue brigade of the Jujube Mining Group is responsible for the safety work of 45 pairs of local mines and 12 pairs of mines of the group company within the jurisdiction. With the gradual deepening of mine production, the extension of the production front, and the frequent succession of mines, the task of unsealing and liberating the roadways is also increasing; during the process of gas discharge by the national mine rescue team, the rescue team suffered an accident of their own casualties a lot of. In 1995, when the rescue team of a mine in Southwest China was discharging gas, a gas explosion was caused due to improper measures taken by the rescue team, causing 1...

AI Technical Summary

Problems solved by technology

Especially in the process of gas discharge, it is difficult to control the air volume accurately and automatically. It is either large or small. If it is too large, it will easily cause gas to exceed the limit; if it is too small, it will delay the discharge time and affect the production of the mine.
