[0044] Working principle of the present invention:

[0045] When the present invention is used, the staff places the crucible containing the rare earth on the upper end of the support plate 27, and then the staff can install the sealing top cover 8 stably, and then the staff controls the heating plate 24 to start working to heat the rare earth. Then, after the temperature inside the purification tank 6 reaches the set height, the water vapor inside the liquid mixture of the rare earth will evaporate, and then the components in the mixture have different saturated vapor pressure properties at the same temperature, so as to separate and purify the rare earth mixture inside the crucible. Then, when the heat inside the purification tank 6 is radiated, the staff will cool the coolant from the heat dissipation water injection pipe 9 and the heat dissipation water inlet pipe 12. Correspondingly injected into the sealed top cover 8, the sealed bottom cover 15 and the interior of the purification tank 6, the coolant will then be separated and guided by the diverter plate 29, the diverter hole 30 and the guide partition plate 31, thereby effectively increasing the efficiency and uniformity of heat dissipation of the sealed top cover 8, the sealed bottom cover 15 and the purification inner tank 18. At the same time, the coolant will then be discharged from the heat dissipation drain pipe 10 and the heat dissipation outlet pipe 17, and the coolant will be reused. Later, when the rare earth crucible is taken out from the interior of the purification tank 6, the staff can control the adjustment motor 5 to work, which will drive the sealed bottom cover 15 to descend through the screw 14, thereby facilitating the staff to take out the rare earth crucible.
