一种干法选煤机内煤粉清理装置
本技术一种干法选煤机内煤粉清理装置,涉及一种在干法选煤机维养时,对干法选煤机内的残留粉尘进行清理的装置,属于煤矿设备领域。特别涉及一种通过振动破碎将干法选煤机内粉尘清理掉的装置。
技术介绍
目前,在煤炭采掘后,需要进行分选,目前使用较多的是干法选煤,干法选煤是利用煤与矸石的物理性质差异,在空气流中、机械振动或摇动的共同作用下进行分选,粒度大的块状物不参与流化沉在床层底部,而粒度小的颗粒能够流化并不断溢出床层,从而达到分离的目的,在流化过程中,由于选煤机内的结构阻碍,会使得参与流化的小颗粒沉积在受阻区域,同时临界点的颗粒物也会悬浮在选煤机内,使得选煤机内的各处充满粉尘,虽然选煤机上自带有除尘的风机,但对于死角位置积攒的粉尘,受阻区的粉尘很难进行清除,长期下去,粉尘结垢附着在洗煤机内壁上,使得后期清扫更加困难,尤其当环境湿度增加时,煤粉更容易凝结成块,残留选煤机内,使得除尘口堵塞,影响除尘效率。
技术实现思路
为了改善上述情况,本技术一种干法选煤机内煤粉清理装置提供了一种通过振动破碎将干法选煤机内粉尘清理掉的装置。结构简单,方便实用。本技术一 ...
