摘　　要：为了提升选矿厂设备的自动化覆盖率,针对目前部分井下矿山选矿厂由于原矿湿度大引起皮带下料口堵料时,需要依赖人工手动调节振动电机的偏心铁块以改变其振动幅度,从而疏通下料漏斗堵料的问题,采用变频调速控制方法对振动电机进行了研究,设计了一种变频调速控制系统,根据料仓下料口原料的潮湿程度,无需停机,通过本地或远程给定速度,变频调速控制系统自动控制振动电机的振动幅度,使下料顺畅,避免下料口堵料现象。该系统实现了远程启动/停止和数据显示同步,还可扩展使用触摸屏进行远程显示和控制。系统投入使用后,设备运行平稳正常,系统结构简单,维护方便,具有很高的实用价值和推广价值。In order to improve the automatic coverage of concentrator equipment,in some under⁃ground mine concentrator,when the raw ore humidity is high and the belt feeding port is blocked,it is nec⁃essary to manually adjust the eccentric iron block of the vibration motor to change its vibration amplitude,so as to dreg the blocking of the feeding funnel.The vibration motor is studied by adopting the frequency con⁃version speed control method.A frequency conversion speed regulation control system is designed.Accord⁃ing to the humidity of the raw materials at the discharge port of the silo,there is no need to stop the ma⁃chine,and the frequency conversion speed control system automatically controls the vibration amplitude of the vibration motor through a local or remote given speed,so that the blanking is smooth and the blocking phenomenon of the blanking port is avoided.The system enables remote start/stop and data display synchro⁃nization,and can also be extended to use the touch screen for remote display and control.After the system is put into use,the equipment runs smoothly,the system structure is simple,the maintenance is convenient,and it has high practical value and popularization value.
