一、引言 我厂配煤工段原设计是某型号电子皮带秤7台。配煤小皮带电动滚桶到从动滚桶之间轴心距是4m。皮带短小,设备拥挤。由于秤体几乎对着下料口,冬天经常有冻煤块的冲击和过负荷,称重传感器易损坏。另外,秤的配套机械复杂,机械故障率高。又因环境恶劣,设备安装非常紧凑,这给维护带来极大困难,所以这套设备自投产以来就没能正常运行起来。几经改造都没成功。只好采用土办法“跑盘”进行炼焦配煤比。这种办法不但劳动强度大,且焦炭质量是无法保证的。 I. INTRODUCTION Our original design of coal blending section is a model of electronic belt scale 7 sets. Small coal belt motorized drum to the driven drum between the axis distance is 4m. Short belt, equipment crowded. As the scale body almost against the feed, in winter, often the impact of frozen coal and overloading, weighing sensor vulnerable. In addition, the balance of mechanical complexity, high mechanical failure rate. Due to the harsh environment, the installation of the equipment is very compact, which brings great difficulties for maintenance. Therefore, the equipment has not been able to operate normally since it was put into production. After several reforms did not succeed. Had to use the soil method “running plate” coking coal ratio. This approach not only labor-intensive, and coke quality can not be guaranteed.
