Abstract

The invention relates to an electrolytic furnace and belongs to the technical field of rare-earth metallurgical equipment and application of the rare-earth metallurgical equipment. The electrolytic furnace comprises an adjusting component (3), a sealing cover (4), a negative electrode (8), a positive electrode (9) and an impermeable insulating component (20). The negative electrode (8) and the positive electrode (9) are vertically distributed in parallel, and the positive electrode (9) can move to adjust the distance between the negative electrode and the position electrode. The electrolytic furnace has the beneficial effects that reaction gas is prone to escaping and easy to collect, products are easy to collect, slag generated in reaction is easy to clean, a product taking out component is easy to install, and the products are easy to take out; the service life of the negative electrode is long; a plurality of negative electrode and positive electrode sets can be arranged in the same electrolytic furnace to bring convenience to achieving large-scale and automatic production; energy is further saved, and clean production is achieved; and the negative electrode can be cooled by a cooling device to enhance the effect of preventing electrolyte from leaking, slow down oxidation loss of the negative electrode and reduce the resistance of the negative electrode.
