摘要
基于五里堠煤矿选煤厂在选煤过程中脱介筛筛板频繁出现脱落,导致脱介筛上大量精煤进入介质系统内,造成管路堵塞以及筛选系统瘫痪等,严重制约着选煤厂安全高效选煤的问题,五里堠煤矿通过技术研究,决定对选煤厂脱介筛筛板安装一套在线脱落监测装置。通过实际应用效果来看,该装置投入使用后,脱介筛筛板脱落故障率降低3%以下,提高了选煤效率,取得了显著应用成效。
Based on the frequent shedding of the desmearing screen plate in the coal processing plant of Wulizhou coal mine, which causes a large amount of fine coal on the desmearing screen to enter the media system, resulting in blockage of the pipeline and paralysis of the screening system, which seriously restricts the safe and efficient coal processing in the plant, Wulizhou coal mine decided to install an online shedding monitoring device for the desmearing screen plate in the coal processing plant through technical research, and analyzed the structure principle of the device. The device has been put into use to reduce the failure rate of the desmearing screen plate by less than3%, which has improved the coal separation efficiency and achieved significant application results.
