Abstract:
According to the conditions of the low level of automation and low labour productivity,an automatic control system for flotation process was designed and developed innovatively based on the ControlLogix series software and hardware platform of Rockwell Company. The structure and function of the control system are introduced carefully. The control strategies of the pulp level,the air flowrate and the flotation reagent feeding are described in detail. The control software and human - machine interface are designed and developed. The actual industrial application results show that the control system operates steadily,safely and reliably,the worker labor intensities are decreased obviously,and the work condition is improved,the competitiveness of the enterprise is enhanced.
Key words: flotation, control system, process control
摘要:
针对我国赤铁矿浮选生产过程自动化水平不高、劳动生产率低、工艺指标精矿品位和尾矿品位波动严重的现状,采用美国Rockwell 公司的ControlLogix 系列软硬件平台设计开发了浮选过程自动控制系统。详细介绍了控制系统结构、控制系统功能、智能优化设定层和底层回路层的控制策略,以及浮选过程自动控制系统应用软件和人机交互监控界面的开发过程。将本文提出的自动控制系统应用于酒钢选矿厂,长期运行结果表明,系统运行稳定、安全可靠,减轻了现场操作人员的劳动强度,提高了劳动生产率,进而提升了选矿厂的企业竞争力。
