自动配煤过程中若干问题的优化技改

Optimization of Technical Innovation on Some Problems in the Process of Automatic Coal Blending

孝义市金晖煤焦有限公司备煤车间采用电子秤自动配煤,但煤仓空气炮控制却采用手动控制。在运行过程中存在手动打空气炮不及时,造成单种煤断煤时间长,经常引起断煤联锁停车,甚至影响到焦炭质量;在启停车过程中,因个别煤仓距离汇总皮带较远,导致在启停车5 min时间内单个或多个煤种缺失,直接影响了入炉煤质量。后经过对系统进行优化技改,完善了配煤系统缺陷,保障了配煤执行精度。

The electronic scale is used to control the coal blending automatically in the workshop of Xiaoyi Jinhui Coal Coke Co.,Ltd,but the air gun is still applied manually in the coal bunker,which takes a long time to supply single kind of coal and makes a nocoal linkage stopping of equipment; even the coke quality is affected when it cannot be operated in time. The coal quality as fired is effected as single or several kinds of coal cannot be feed in time in the process of start-stop by 5 minutes since the distance is too far between the coal bunker and main transfer belt. After the improvement and utilization for the coal blending system,the precision of blending coal is enhanced.
