煤炭翻车机冻煤滞留问题的成因分析与处理技术研究OA

During the long-distance railway transportation and the process of coal unloading operation in North China in winter,the frozen coal always adheres to the inner walls of car dumpers and of wagons,which frequently challenges the coal unloading operation in winter,such as the reduction of coal unloading efficiency,hopper blockage,unbalanced freight wagon and other safety hazards.In addition,the wear and tear of equipment leads to higher operation costs.Based on the above issues,a systematic research was carried out for the treatment technologies of frozen coal based on the combination of the traditional and advanced approaches,including such innovations as deformable discharge hoppers and a frozen coal monitoring system.The research findings could technically support the efficient operation of coal unloading systems in severe cold regions.
