摘　　要：掌握矿浆性质参数对后续煤炭洗选效率以及经济性等均有较大影响,现阶段采用的人工检测方式存在检测间隔时间长、检测难度大以及劳动强度高等问题。为此,提出一种浮选矿浆性质多参数在线监测系统,该系统通过传感器、PLC等实现矿浆参数的实时测定,并依据现场实际情况对各传感器安装位置进行阐述。现场应用后,该系统可每隔2 h即可监测一次矿浆性质参数,监测结果与现场人工检测结果一直,取得较好应用效果。研究成果可在一定程度上提升矿浆参数监测自动化水平。Mastering the pulp property parameters has a great impact on the subsequent coal washing efficiency and economy.The manual detection method adopted at this stage has the problems of long detection interval,difficult detection and high labor intensity.Therefore,a multi parameter on-line monitoring system for flotation pulp properties is proposed.The system realizes the real-time measurement of pulp parameters through sensors and PLC,and expounds the installation position of each sensor according to the actual situation on site.After field application,the system can monitor the pulp property parameters every 2 hours.The monitoring results are consistent with the field manual detection results,and good application results are obtained.The research results can improve the automation level of pulp parameter monitoring to a certain extent.
