摘　　要：针对目前铝土矿石品位逐年下降,导致赤泥量增加,影响沉降槽沉降性能,同时结合现有沉降槽的生产实践现状,介绍了将高效深锥槽的中心井进料系统由文丘里改为溜槽式进料系统的改造方法及具体实施步骤。利用沉降槽高度落差,实现管道自溢流,退出溢流泵,通过具体方案的落地实施,实现降低用电能耗及提高沉降槽处理能力的目的。In view of the present situation that the ore grade of bauxite which decreases year by year leads to the increasing amount of red mud and affects the settling performance of the settling tank,and combining with the current production practice of the existing settling tank,this paper introduces the upgrading method and implementation steps of the central shaft feed system of efficient deep cone tank from venturi to chute type.The self-overflow of pipe be realized by using the height drop of settling tank,so that the overflow pump can be removed.Through the implementation of a specific plan,the purposes of reducing power consumption and improving the treatment capacity of the settling tank are realized.
