Abstract

The utility model relates to an electrolytic device used in rare earth metal production. The utility model can provide a rare earth metal production used electrolytic equipment with high power, big electrolytic current and high product yield. The utility model consists of four rectifiers, four groups of electrode elevator, an electrolyzer, an ingot cast machine and a cable. The anodes of four rectifiers separately connect with four graphite anode tubes of the electrolyzer through a cable, and cathodes connect with horns of four groups of electrode elevator through the cable. The other end of the horn connects with the four cathode cores of the electrolyzer. The ingot cast machine is fixed on the lower part of the electrolyzer. The utility model has high electrolytic equipment power, big electrolytic current, low unit product current drain and high metal recovery rate; greatly improves unit output and product quality stability; reduces production cost; and lightens labor intensity.

Description

A kind of rare earth metal production electrolyzer

Technical field:

The utility model relates to a kind of electrolyzer, particularly a kind of rare earth metal production electrolyzer.

Background technology:

It is 2000-3000A mostly that existing rare earth metal is produced electrolyzer power, and Faradaic current is little, unit product power consumption height, and efficient is low, and rare earth metal output is few, and is second-rate, and metal recovery rate is low, the product cost height.

Summary of the invention:

The utility model can provide a kind of plant capacity height, and Faradaic current is big, the rare earth metal production electrolyzer that product production is high.Its four rectifier, four groups of electrode positioning mechanisms, electrolyzer, pig moulding machine and cable constitute, four rectifier anodes are connected in four graphite anode tubes of electrolyzer by cable respectively, negative pole is connected in the horn of four groups of electrode positioning mechanisms by cable, and the horn the other end connects four negative pole cores of electrolyzer, and the electrolyzer below is fixed with pig moulding machine.

Electrolyzer described in the technique scheme includes four graphite anode tubes, outer wall is a steel plate, inwall is a graphite cuvette, it between steel plate and graphite cuvette flame-proof thermal insulation material, the negative pole core is tungsten or molybdenum, the electrolyzer bottom is a conical tube, is fixed with Medium frequency induction coil and thermoelectric lotus root conical tube week, and the mouth of pipe is fixed with slide gate nozzle.

The rated current of rectifier described in the technique scheme is 5000 peaces.

Pig moulding machine described in the technique scheme can be according to the speed governing of rare earth metal flow quantity.

The utility model electrolyzer power height, Faradaic current is big, and the product yield in unit time improves greatly, and the unit product power consumption is low, the constant product quality raising, production cost reduces, the metal recovery rate height, labor strength alleviates.
