| 摘 要： | 浮选机内各动力学分区的流动特征复杂。本文选取单槽容积0.2m3KYF型充气机械搅拌式浮选机为研究对象,采用PIV测试技术开展运输区的结构特征和动力学特征的研究。研究表明运输区在半个槽体的取截面内的轮廓形状整体呈现为左边为直线,右边折弯线,上下近似直线的近梯形结构,具有高度和宽度两个主要结构特征。运输区轮廓边界处的动力学特征存在明显差异。本研究加深了对浮选机运输区特征的理解,有助于通过调控运输区特征方法解决大型机械搅拌式浮选机粗粒矿物回收率低的难题。

| Abstract: | The flow characteristics of each dynamic region in the flotation machine are complex. In this paper, 0.2m3 KYF air-forced mechanical flotation machine was selected for research object, and PIV test technology was used to study the structural and dynamic characteristics of the transportation area. The results shows that the contour shape of the transportation area in the section of half of the tank is presented as a straight line on the left side, a curved line on the right side, and a nearly trapezoidal structure with a straight line on the top and bottom. There are significant differences in the dynamic characteristics at the boundary of the transport area. This study has deepened the understanding of the characteristics of the transport zone of flotation machine, which is helpful to solve the problem of low recovery of coarse mineral in large-scale mechanical stirred flotation machine by regulating the characteristics of the transport zone. |
