Abstract

The utility model is related to a round electrolytic tank with 10,000 ampere for producing rare earth metal by fusion electrolysis. The tank comprises a multilayer anode and a plurality of cathodes. In the embodiment provided in the utility model, the anode 1 has double layers, wherein the inner layer is cylindrical and positioned in the center of round electrolytic tank, the outer layer is annular; a plurality of the cathodes are evenly distributed in a ring shape and are equipped in the center of the double-layer anode 1. The electrolytic tank in the utility mode has large effective volume, strong current intensity, low electricity consumption, improved yield and stable and even quality.

Description

Circular Wan An training electrolyzer of rare earth metal is produced in fused salt electrolysis

Affiliated technical field

The utility model is circular Wan An training electrolyzer that rare earth metal is produced in fused salt electrolysis, belongs to the electrolyzer technical field of rare earth metal.

Background technology

At present, being used for fused salt electrolysis produces the electrolyzer of rare earth metal and has two kinds.A kind of is Wan An training electrolyzer, and this electrolyzer is square, and non-circular, its main drawback is that the electrolyzer volume is big, but useful volume is little, electrolyzer cost height, non-uniform temperature, compares with little electrolyzer, and power consumption does not reduce or reduces few.Another kind of electrolyzer is the circular little electrolyzers of 3 kiloamperes, though its relative useful volume is big, strength of current is generally below 4000 amperes, and anode is individual layer, and its output is not high, quality is also unstable, and power consumption is also high.

The utility model content

In order to overcome above-mentioned two kinds of deficiencies that electrolyzer exists separately, the utility model provides a kind of fused salt electrolysis to produce circular Wan An training electrolyzer of rare earth metal, to increase the electrolyzer useful volume, improves strength of current, increases output, and stabilised quality reduces power consumption.

The technical scheme that its technical problem that solves the utility model adopts is: circular Wan An training electrolyzer of rare earth metal is produced in fused salt electrolysis, comprises crucible, negative electrode, anode etc., and anode 1 is a multilayered structure, and negative electrode 2 is many root architectures.

The beneficial effects of the utility model are: the electrolyzer useful volume is big, and strength of current is big, and it is low to consume energy, and output increases, steady quality.
