对跳汰选煤行业的发展情况进行了调查研究,制定了以井下跳汰机排料系统的自动化为研究对象。首先对跳汰机排料系统的电气自动化控制的发展现状进行了分析,然后对于跳汰机控制系统的结构技术方面进行分析,主要包括排料系统电气自动控制的基本要素、工况条件、结构组成、模糊控制计算进行探讨。最后对排料系统的自动化控制技术的优势与不足进行了相互对比分析。对跳汰机排料系统在实际中的应用提供一个可靠的理论价值。 The development of the jigging coal dressing industry was investigated and the automation of the discharge system of the underground jig was set as the research object. First of all, the status quo of the electrical automation control of the jig discharge system was analyzed. Then the structural technology of the control system of the jig was analyzed, including the basic elements of electric automatic control of the discharge system, working conditions, structure Composition, fuzzy control calculation to explore. Finally, the advantages and disadvantages of the automatic control technology of the discharge system were compared with each other. The jig discharge system in practice provides a reliable theoretical value.
