摘要(Abstract)：

针对传统稀土萃取混合澄清槽存在的问题,提出了在澄清室增加搅拌装置以提高澄清效率的方法。通过对四斜叶搅拌桨、Intermig桨及框式搅拌桨等不同桨型搅拌对澄清度影响的研究,证实四斜叶桨是合适的桨型,经搅拌之后,澄清室两相分离效果明显优于传统混合澄清槽,澄清度平均提高30%以上。在转速20,30,40和50 r·min-1条件下,搅拌桨离底距离分别为4.0,5.5,7.0,8.5和10.0 cm,搅拌桨距溢流口距离分别为10,13和16 cm时,对四斜叶桨搅拌澄清度的研究结果表明,低转速下澄清效果更好,搅拌桨距离溢流口越近澄清效果越好,而搅拌桨离底距离8.5cm,即处于两相混合带附近时澄清效果最佳。在此基础上,根据因次分析原理和试验数据建立了澄清度因次公式。
