颚式破碎机自适应控制系统的设计与实现

Design and Realization of Adaptive Control System for Jaw Crusher

以美卓C140颚式破碎机为控制对象,利用激光物位检测技术,设计配套传感器系统,通过在破碎机上方合适位置安装2台激光物位计,解决了破碎腔中的料位和下部矿仓料位检测的难题。以破碎机电流和破碎腔料位为控制变量,利用自适应控制算法,调节重板给矿机的给矿速度和启停,实现了美卓C140颚式破碎机自动给矿运行。3条颚式破碎系统实现自动化后操作人员数量由原来的14人减少至5人,操作内容也由原来机械重复式操作改为简单的定时巡检,达到了人员优化和减轻作业人员劳动强度的目的。该系统填补了地下矿山颚式破碎机自动控制的空白,具有很好的推广价值。

Taking Metso C140 jaw crusher as a case,the laser level detection technology is adopted to design a matching sensor system.Two laser level meters are installed in the proper position above the crusher,which solves the problem of material level detection in the crushing chamber and the lower ore bin.Taking the crusher current and the level crushing chamber as control variables,the automatic feeding operation of Metso C140 jaw crusher is realized by adjusting the feeding speed and start-stop set of the heavy plate feeder and using adaptive control algorithm.After the three jaw crushing systems are automated,the number of operators is reduced from the original 14 to 5,and the operation content is changed from the original mechanical repetitive operation to simple regular inspection,which achieves the purpose of personnel optimization and labor intensity reduction of operators.The system fills the blank of automatic control of jaw crusher in underground mine and has a good popularizing value.
