【技术实现步骤摘要】
方便清理的煤炭风选机主通风道
本专利技术涉及煤矿设备
,具体涉及一种方便清理的煤炭风选机主通风道。
技术介绍
煤炭风选机是一种将大块煤炭粗碎、细碎及风力输送的常用的煤炭生产用机械设备,目前,在对粉碎后的煤炭进行风力输送时,通常是在风道的一端设置风机,通过风机将细碎的煤炭颗粒输送至布袋式除尘器进行细粉煤的回收,在风力输送过程中,会有煤炭颗粒附着在风道的四壁,尤其是当风机长时间使用后风力不足时,风道四壁的煤炭颗粒附着现象十分严重,必须对风道进行清理,但是,风道长度较长,通常都在八米以上,在清理时,往往需要操作工人从风道的一端钻入风道内部,清扫时间较长,劳动强度大,清理十分困难。
技术实现思路
综上所述,为了克服现有技术问题的不足,本专利技术提供了一种方便清理的煤炭风选机主通风道,它是在风道的下端沿风道的长度方向设置多个清扫用的开口,开口上设置可翻转开合的挡板,同时开口上设置封盖,煤炭风选机正常使用时挡板闭合,同时封盖将封口密闭,当清理风道时,打开封盖,挡板打开,清扫工人从挡板的间隙清扫风道四壁,不需要人工钻入风道内,从而减少清扫风道的难度,提高清扫效率,降低清扫所需 ...
