【技术实现步骤摘要】
本技术涉及一种除尘器,具体的说是一种开合式防喷孔复合吸尘罩。
技术介绍
目前,煤炭在国民经济能源结构中占据很重要的地位,随着国民经济的发展,煤炭的需求也越来越大,在原煤产量快速增长的同时,也必须保证矿井的安全高效开采。现在矿井瓦斯是煤矿开采中,通常需要在煤层中进行钻孔,由于煤层干燥,在钻孔时煤尘飞扬,同时还夹杂着瓦斯,给操作工人的身体造成极大的伤害,也给煤矿安全带来很多不安全因素。
技术实现思路
本技术所要解决的技术问题是,克服现有技术的缺点,提出一种开合式防喷孔复合吸尘罩,从而有效防止煤尘与瓦斯大量从孔内涌出。为了解决以上技术问题,本技术提供一种开合式防喷孔复合吸尘罩,包括吸尘罩本体,所述吸尘罩本体由上盖体和下盖体组成,所述上盖体与下盖体之间一侧由轴销连接,另一侧由快速搭扣锁紧密封;所述上盖体上部设有吸尘通道,所述下盖体下部设有粉尘排出口;所述吸尘罩体的前端设有通向煤孔的管道,所述管道上连接有快卡钢圈;所述吸尘罩本体内部和外壁至少设置两道能通过钻杆的开孔钢板,所述钢板的开孔轴线与所述通向煤孔的管道轴线一致。本技术进一步限定技术方案是:前述的开合式防喷孔复合吸尘罩,所述开孔钢板中间夹有硅橡胶密封垫对钻杆进行密封。进一步的,前述的开合式防喷孔复合吸尘罩,所述通向煤孔的管道内衬有H62铜板,管道的另一端伸进预先开好的钻煤孔内,能做到与煤孔连接处密封不漏气。与现有设备先比,本技术设计极大方便了井下窄小孔口处吸尘罩的快速安装和拆卸,提高了工作效率,既保证全部粉尘和瓦斯被完全收集,又能分别合理处置,同时通过吸尘罩下端落下的大颗粒煤粒情况观察到钻孔内回风情况,以确定是否有塌 ...
