Embodiment Construction
[0025] The present invention will be described in detail below in combination with specific embodiments.
[0026] see figure 1 , figure 2 and image 3 , the rare earth electrolytic cell of this embodiment includes a cell shell, a cell liner, a cathode group structure, an anode assembly, a column girder frame, a cell cover plate, a blanking system, a shell breaking system, a gas collection system, an anode lifting and a bus transfer system And intelligent slot control system. The electrolysis current of the rare earth electrolyzer is 10-200kA, the electrolyte system used is REF3 (86-97%)-LiF (3-14%), the electrolysis temperature is 850-1250°C, and the anode current density is 0.7-2.0A / cm2, The cathode current density is 0.6-3.2A / cm2.
[0027] The tank shell 1 is a rectangular structure welded with steel plates, and the sides are welded with a coaming plate, a tank edge plate 7 , a stiffener plate and a cooling air duct 13 .
[0028] The trough cover plate 2 is a double-la...
