摘　　要：对新余钢铁股份有限公司焦化厂备煤车间以阻旋式感应器为主体的煤斗堵塞保护控制器在工作中存在的问题进行分析,然后针对这些问题实施有效的技术改造.实际应用证明,以限位开关为核心的新型煤斗堵塞保护控制器可以替代阻旋式感应器.采用新型煤斗堵塞保护控制器,对于延长保护控制器的使用寿命、避免满斗堵塞、降低运行成本与维护费用、提高生产效率具有重要的意义.This paper analyzes the problems existing in the work of the coal bucket blocking protection controller with the anti-rotary sensor as the main body in the coal preparation workshop of the Coking Plant of Xinyu Iron and Steel Co., Ltd., and then carries out effective technical transformation for these problems. The practical application proves that the new type of coal bucket blocking protection controller with the limit switch as the core can replace the anti-rotary sensor. It is of great significance to adopt a new type of coal bucket blocking protection controller for prolonging the service life of the protection controller, avoiding full bucket blockage, reducing operation cost and maintenance cost, and improving production efficiency.
