摘　　要：为了揭示变频对给料机物料参振质量的影响,采用离散元对实际干熄焦振动给料机的物料参振质量进行了模拟研究,探讨了变频时给料机的物料参振质量的变化。模拟结果表明：当进料量为185 t/h时,振幅为3.5 mm,频率在25~35 Hz变化时,物料参振质量在800~1 370 kg变化。以上所做的工作为给料机的电机功率的准确确定及变频工艺顺利实现提供了理论支持。In order to reveal the influence of variable frequency on vibratory feeder materials weight participating in vibration, it adopts discrete element to make simulation research on the actual coke dry quenching vibratory feeder, and discusses the changes of vibratory feeder materials weight participating in vibration by variable frequency. The simulation results show that when the feed rate is 185 t/h, the amplitude is 3.5 mm,and the frequency changes from 25 Hz to 35 Hz, the materials weight participating in vibration changes between 800 kg to 1 370 kg. The work above provides the theoretical supports for accurate determination of the feeder motor power and smooth realization of variable frequency process.
