为提高选煤厂过滤机工作效率，避免过滤机主轴出现堵转问题，在对过滤机结构以及现场运行存在问题分析基础上，从主轴转速、放料过程等方面对过滤机系统进行优化，并对具体优化过程进行阐述。优化的过滤机系统不仅可保证产品含水率在合理范围内而且矿浆槽放料不受上料筒液位限制，从而有效避免主轴堵转问题。现场应用后，主轴堵转发生间隔由平均 3 个月提升至 9 个月，年可减少投入约 10.3 万元，取得较为显著的优化效果。研究成果可为类似情况下其他选煤厂过滤机优化提供经验借鉴。“,”In order to improve the working efficiency of the filter in the coal preparation plant and avoid the blocking problem of the filter spindle, based on the analysis of the filter structure and on-site operation problems, the filter system is optimized from the aspects of spindle speed, discharge process, etc. , And elaborate on the specific optimization process. The optimized filter system not only ensures that the moisture content of the product is within a reasonable range, but also that the slurry tank discharge is not restricted by the liquid level of the upper barrel, thereby effectively avoiding the problem of spindle blockage. After the field application, the interval between the occurrence of spindle stalls has been increased from an average of 3 months to 9 months, and the annual investment can be reduced by about 103,000 yuan, and a more significant optimization effect has been achieved. The research results can provide experience and reference for the optimization of filters in other coal preparation plants under similar conditions.
