摘要
煤矿胶带输送机是煤矿运输系统中的主要运输设备.在运输过程中,胶带与滚筒、托辊滚动及胶带与物料间都会发生摩擦而产生较大热量,容易引发火灾,甚至会发生瓦斯爆炸事故,直接威胁矿工的生命安全.基于此,分析煤矿胶带输送机发生火灾的原因,针对火灾诱因,在胶带机上设计自动灭火装置、设置自动喷淋系统、合理布置水幕群喷头等,同时预防"危险托辊",防控电缆和胶带间、金属支架和转动部门间的摩擦,并推广应用离心式耦合器等,以尽可能降低胶带输送机发生火灾的概率.
Abstract
The coal mine belt conveyor is the main transportation equipment in the coal mine transportation system.During the transportation process,there will be friction between the belt and the drum,the rollers,and the belt and materials,which can generate large amounts of heat and easily cause fires.In severe cases,gas explosions may even occur,directly threatening the safety of miners.Based on this,this article analyzes the causes of fires in coal mine belt conveyors.In response to the causes of fires,an automatic fire extinguishing device is designed on the belt conveyor,an automatic sprinkler system is set up,and water curtain group nozzles are reasonably arranged.At the same time,it is necessary to prevent"dangerous rollers",prevent friction between cables and belts,metal supports and rotating departments,and promote the use of centrifugal couplers to minimize the probability of fire in belt conveyors.
