梳型喷嘴清扫器在选煤厂的应用

为提高选煤厂输送带清扫器的工作效果,利用高压风通过梳型喷嘴形成的风幕隔离作用,使黏附在输送带回程段的物料较好地进行回收,避免污染输送带栈桥,有效改善了作业环境,降低了人员劳动强度,并减少了设备磨损及材料消耗。结果表明,梳型喷嘴清扫器在产品输送带上可以较低的风压和风量除去99%以上的回程物料。 In order to improve the working effect of conveyor belt cleaner in coal preparation plant,the high pressure air through comb-type nozzle was used to separate the air curtain,so that the materials adhered to the return section of the conveyor belt can be recovered well and the conveyer belt trestle can be avoided.It can effectively improve the working environment,reduce the labor intensity,equipment wear and material consumption.The results show that the comb nozzle cleaner can remove more than 99% of the backhaul materials with lower air pressure and air volume on the conveyor belt after washing
