基于解决选煤厂脱落筛板卡堵输煤管道的问题研究
Research on Solving the Problem of Coal Conveying Pipeline Blockage Caused by Falling Sieve Plates in Coal Preparation Plants

煤炭作为我国的主要能源资源，不仅为主要的能源消耗燃料，更是不可或缺的工业生产原料，为了煤炭高效清洁利用，煤炭洗选必不可少。煤炭洗选工艺中筛分设备发挥着至关重要的作用，筛分设备的高效稳定运行直接关系着生产安全、经济效益。筛板脱落在筛分设备运行中非常常见，也不可避免，难于及时发现，其引发的堵管堵仓事故导致设备损毁，系统瘫痪，处理起来更是耗时费力，给正常生产带来很大威胁。本文经过系统分析，着力于通过转换信号传导方式及时发现报警筛板脱落，减少事故影响，提高系统生产安全和效率。
As the main energy resource in China, coal not only consumes fuel as the main energy source, but also is an indispensable industrial production raw material. In order to achieve efficient and clean utilization of coal, coal washing is essential. The screening equipment plays a crucial role in the coal washing process, and the efficient and stable operation of the screening equipment is directly related to production safety and economic benefits. The detachment of sieve plates is very common and inevitable in the operation of screening equipment, which is difficult to detect in a timely manner. The blockage of pipes and warehouses caused by it leads to equipment damage, and sys-tem paralysis, and processing is time-consuming and laborious, posing a great threat to normal production. Through systematic analysis, this article focuses on timely detecting the detachment of alarm screen plates by converting signal transmission methods, reducing the impact of accidents, and improving system production safety and efficiency.
