Dumbbell-shaped rare-earth metal electrolytic graphite tank

Abstract

The invention relates to a dumbbell-shaped rare-earth metal electrolytic graphite tank. The dumbbell-shaped rare-earth metal electrolytic graphite tank comprises a tank body, wherein an anode tank is arranged in the tank body, an anode group is arranged in the anode tank, the anode group comprises a plurality of arc-shaped anodes and special-shaped anodes which are positioned among the arc-shaped anodes, symmetrical inward concave cambered surfaces are formed on both sides of the special-shaped anodes, the radius of the cambered surfaces is equal to that of the arc-shaped anodes, and the central angles of the cambered surfaces and the arc-shaped anodes are complementary; a hollow circle is enclosed by the arc-shaped anodes and the special-shaped anodes, and a cathode is positioned in the center of the hollow circle. By adopting the dumbbell-shaped rare-earth metal electrolytic graphite tank, the surfaces of the anodes are all on an equipotential surface which uses the cathode as the center to the maximum, so that ions in an electrolyte are easy to diffuse, rare-earth electrolytic reaction is uniform, the single yield is effectively increased, and additionally, electrolytic energy consumption is greatly reduced.

Description
