J IngXIo印sulZhon tongfeng ehae帕n井下破碎站通风除尘(dust Colltrol in stationof treaker)井下破碎酮室通风换气和破碎机系统的密闭除尘措施。井下破碎铜室应有独立的回风系统,如果无独立的回风系统,则含尘气流需经除尘器净化,达到卫生标准后,排往进风巷道。铜室的通风量一般按每小时换气4一6次计算。破碎酮室中,破碎机的供矿系统、破碎机构和卸矿系统都应有密闭抽尘装置(见图)。当直接给矿,落差小于lm时,可设密闭罩,同时向矿石喷雾洒水。如果用长溜槽或格筛给矿,在设密闭罩的同时,还应有抽尘系统。如果落差较小,且上部又有抽尘系统,则下部卸矿口可只设密闭罩而不抽尘;如果落差大,则应设抽尘系统。抽风量的大小,可根据破碎机规格、给矿方式和矿石落差来确定。稼衅 破碎机密闭抽尘系统示意图 l一破碎机密闭;2一吸尘罩;3一除尘器和风机; 4一排风巷道;5一卸矿井;6一进风巷道 (陈荣策)
