Background

The mixer-settler has the advantages of simple structure, low investment, stable operation, high extraction grade efficiency and the like, and is widely applied in the liquid-liquid extraction process. In a typical mixer-settler, a front chamber is arranged at the bottom of a mixing chamber to ensure the suction force of a stirring paddle on a light phase and a heavy phase, and under the process of treating materials with higher viscosity or easily precipitating impurities in the mixing process, the mixer-settler is often required to be cleaned regularly to ensure the stable operation of the mixer-settler, but the front chamber has small operation space and is difficult to clean, and even the safety accident is easily caused in the cleaning process; typical mixer-settler mixers, typically of the paddle or pump type, not only allow for thorough mixing of the heavy and light phases, but also draw the heavy phase from the upper clarification chamber into the mixing chamber. The paddle type or pump type stirrer has large design workload, complex calculation and slightly improper design, and particularly, the suction force is often insufficient in the design process of an industrial mixer-settler, the contradiction that the stirring rotating speed is reduced and the sufficient suction force is obtained appears, and the production accidents of 'flooding', 'serial phase' and even trough overflowing and the like often occur in the operation process of equipment.
