摘要
提出了最新结构的自然吸气式浮选旋流器. 分析了结构特点及浮选原理, 利用流体力学理论对射流喷嘴作了理论分析, 并确定了该喷嘴的最佳结构及主要参数. 通过实验确定了入料压力是影响旋流器处理量及浮选效果的主要参数,即入料压力越高,旋流器的处理量就越大.入料压力对浮选效果的影响, 其最佳压力大小需经实验加以确定.
The newest structure floatation cyclone of natural inlet air has been designed,the structural characteristics and floatation principle of the floatation cyclone have been analysed. Jet nozzle is studied theoretically by fluid mechanics and optimum structure and main parameters are decided. Feed pressure is a main parameter influencing on the production capacity and floatation results of the floatation cyclone through the experiment. The higher the feed pressure, the more the production capacity. Optimum feed pressure of being better floatation results is determined only through the experiment.
