摘要
针对国内粉末生产过程中粒度分布检验的滞后性,提出了在线颗粒分析仪智能控制系统设计。通过控制采样速度和喂料速度实现样品的在线分析,并实现分析数据的实时采集和传输,实现在线监控。实验结果表明,该系统测试范围达到4～300μm,可持续工作8小时,延时小于1分钟,测试准确度,重复性均达到在线控制的需要。
In order to solve the hysteretic nature problem of particle size distribution in civil powder processing,this paper puts forward a new design of intelligent control system online in particle sizing.Sampling and feeding rate can be controlled in this system.At the same time,analysis online,data collection and transmission real time can be accomplished in this system. The results of experiment show that the test specification is 4-300μm,continuous working period is 8 hours and delayed time is less than 1 minute.The accuracy and repeatability of this system can be reached satisfied effects.
