粉料生产气力输送中的自动称重控制算法

Auto-weighting control arithmetic in the feed of powder lot production

介绍了用于粉料生产气力输送中的自动系统的组成和工作原理,分析了粉料自身的理化特性,由变频器控制的螺旋加料器 送料的快慢,管路中残余剩料以及称重仓中悬浮料等因素对称重准确度、称重速度的影响,提出了“四段式”和“模糊控制”两种控 制算法,并给出了适用的范围和技术条件,通过实践证明这两种控制算法在料粉加工生产中具有良好的应用价值。

This article introduces the composition and working principles of the automatic weighting system in the air and force transportation of powder lot production. It analyzes rational characteristics of powder lot. According to the influences on the weighting-speed of the speed of feeding powder lot of the technology of speed-adjusting by changing frequency and the residual material in the pipeline and the suspended powder lot in the auto-weighted cabinet, and so on, the auther puts forward“four-section”and“fuzzy-control”arithmetic and the suitable fields and the technical conditions. It was proved by practices that these two controlling-methods have high value in powder lot production, and they have been in good use.
