摘　　要：为了有效降低井工煤矿胶带输送机转载点的扬尘,并满足国家要求,井工煤矿转载点应当采用自动喷雾降尘。本文根据单体柱快速升降器压力越大出水量越大的原理,研究了一款转载点机械式自动喷雾装置。该装置安装在胶带输送机机头向后5 m处,上下胶带之间,通过软胶管连接,喷雾口安装位置正对胶带输送机落煤点。胶带输送机上层胶带在重力的作用下,下压到自动喷雾连接装置上,连接装置打开水阀的程度和下压幅度成正比,当胶带输送机上层胶带煤量变大,机头喷雾水量也随之变大,能够充分捕捉煤尘,有效降低落煤点的扬尘。结果表明,转载点机械式自动喷雾装置能够满足有效降尘和自动喷雾的要求。In order to effectively reduce the dust from belt conveyor transfer point in mine and meet the requirements of the state,the transfer point in coal mine should adopt automatic spray dust removal.According to the principle that the higher the pressure,the higher the water yield,a mechanical automatic spray device was studied.The mechanical automatic spray device of the reshipment point was installed at the back 5 m of the machine head of the belt conveyor,between the upper and lower tape,connected by the soft rubber pipe,and the placement of the spray nozzle was directly opposite to the coal drop point of the belt conveyor.Under the action of gravity,the upper rubber belt of the belt conveyor pressed down on the automatic spray connection device.The degree of water valve opened by the connecting device was directly proportional to the pressure range.When the amount of belt coal in the upper part of the belt conveyor increases,the spray water amount of the head of the conveyor increased accordingly,which can fully catch coal dust and effectively reduce the dust of the coal drop point.The results showed that mechanical automatic spray device of reshipment point can meet the requirements of effective dust removal and automatic spray.
