针对目前被动式、自动式阻隔爆技术所存在的局限性,提出一种矿用旋叶风门,阐述了该装置的结构设计及动作原理。该风门集自动阻隔爆、自动实现反风功能于一体,可消除爆炸产生的高温及爆炸冲击波超压,对井下二次爆炸及多次爆炸发挥阻隔爆作用;同时,也可以在井下发生火情时,缩短井下反风所需的时间。 Aiming at the limitations of passive and automatic barrier explosion technology, a mine rotary vane damper is proposed, and its structure design and operation principle are expounded. The damper automatically blocks explosion, automatic wind function in one, eliminating the explosion caused by high temperature and explosion shock wave overpressure, the underground explosion and multiple explosions to play a blocking explosion effect; the same time, you can also occur in the underground fire When, shorten the downhole wind time required.
