The utility model relates to a metallurgical device, in particular to a rotary electrolytic device.

Background

At present, the rare earth metallurgy industry usually adopts an electrolysis mode to produce single rare earth metal or rare earth alloy. At present, the mode of producing rare earth metals by electrolysis is usually of an electric tank fixed type, namely, an electrolytic tank is fixedly arranged, a furnace cover plate is arranged above the electrolytic tank, a graphite flake of an anode is arranged in a graphite tank, a current conducting plate of the anode is arranged on the furnace cover plate, a crucible containing alloy liquid is arranged at the lower part of the electrolytic graphite tank, positive electricity is conducted on the anode, negative electricity is conducted on a cathode for electrolysis, and the problems exist that firstly, in the electrolysis process, the electrolytic tank is stirred by tools regularly for balancing the temperature and/or components of a molten salt system of the electrolytic tank, so the labor intensity in the electrolysis production process is higher; secondly, the distances between the anode graphite sheet and the cathode and between the cathode and the crucible at the lower part of the graphite tank are smaller, if the stirring is too large, the stability of electrolysis is easy to damage, and if the stirring is too small, the effect of balancing temperature and components cannot be achieved, and a stirring tool is required to be kept vertical during stirring, otherwise, the anode and the cathode are easy to generate a short circuit phenomenon through the stirring tool, electrolysis is damaged, or the cathode and the crucible are short-circuited through the stirring tool to damage the crucible, so that the requirements on operators are particularly high, and the recruitment and the culture of electrolysis production operators are not facilitated; thirdly, because the anode conductive plate covers the upper pores between the anode and the graphite tank, tools cannot be put in the anode conductive plate, so that molten salt between the anode and the graphite tank cannot be stirred, and the temperature and/or the composition of the region are greatly different from those of the molten salt between the anode and the cathode.

In view of the above problems, there is a need for an electrolysis production apparatus that is simple to operate and easy to use.
