摘要
针对高压管道粉料输送现场存在人工取样劳动强度大、不安全、污染空气、取样不及时、不均匀及取样量不好控制等一系列问题,开发了一种智能粉料输送在线取样系统。通过详细介绍该系统自动控制的要点及难点,给出了分析和解决方案。经过在平阴山水水泥厂实践证明,该取样系统可产生良好的经济效益。
In view of a series of issues during manual sampling in high-pressure pipeline powder conveyance field such as high labor intensity,unsafety,air pollution,untimely sampling,uneven sampling and poor control of sampling amount,an intelligent on-line sampling system for powder conveyance was developed.The key points and difficulties of automatic control of the system were introduced in detail,and analysis and solution scheme were offered.The practice in Pingyin Shanshui Cement Plant showed the sampling system produced excellent economic efficiency.
