摘　　要：针对深锥沉降槽耙机容易发生过载的问题,对耙机搅拌过程受力进行分析,建立了沉降槽耙机扭矩与传动装置输出功率之间数学模型。设计了基于PLC的沉降槽耙机的负荷监控系统,对耙机扭矩进行实时监控,并与DCS系统之间相互通信,当耙机过负荷运行时,进行报警、停机等措施。运行结果表明,该系统能够避免耙机过载运行,降低系统能耗,保障了系统运行的可靠性。As to the issue of overload in deep cone thickener, force in raker agitating was analyzed and mathematic model between thickener raker torque and actuator power was built. The thickener raker load monitoring system was designed in this paper based on PLC. The system can monitor raker torque in real time, and can communicate with DCS system. The system would alarm or shutdown if the raker overload. The results show that this system can avoid the taker machine overload, and can reduce the energy consumption, and can guarantee system operation reliability.
