摘要
利用CFD软件,模拟了XJM-S型机械搅拌式60 m3圆筒形浮选槽初始虚拟样机的三维流动状态,分析了该样机的流场特征,发现:在各稳流板流道内矿浆流动不均衡,稳流效果不理想;在浮选槽入料口处,存在入料未经假底和叶轮而直接进入浮选槽,以及槽内部分矿浆回流到入料口的不合理现象。根据流场特征分析,提出了对该样机的入料口、稳流板等结构进行改进和优化的建议。
Simulation of the 3D flow pattern in a prototype XJM 60 m^3 cylindrical flotation cell is made using CFD software. Through the analysis of the characteristics of the flow field indicates that ： unideal flow stabilization effect due to imbalanced pulp flow in each stabilizer channel; flow of pulp directly into cell from feed inlet without passing through the false bottom and impeller, causing a port of pulp to flow back to feed inlet. Based on the analysis of the characteristics of the flow field, the measures for structural improvement and optimization of the feed inlet, and stabilizer are proposal.
