Cyclone extraction device and separation system using same

The invention discloses a cyclone extraction device, relates to metal melting, and aims to solve the problem that the extraction mass transfer efficiency is low. The device is characterized in that: the device comprises a cylindrical shell, a main shaft arranged along the central axis of the shell, at least four cyclone reaction discs coaxially fixed on the main shaft, and a cyclone extraction motor used for driving the main shaft, wherein a liquid inlet and a liquid outlet are formed in the upper end and the lower end of the circumferential outer wall of the cylindrical shell respectively, aconnector is arranged between the top end of the shell and the cyclone extraction motor, and the cyclone reaction discs are arranged at equal intervals in the length direction of the main shaft. The cyclone extraction device provided by the invention assists in extraction or back extraction, effectively improves the mass transfer efficiency, and effectively reduces the influence of mass transfer reaction heat. 本发明公开了一种旋流萃
