Reinforcement type rare earth electrolysis graphite crucible

Abstract

The invention discloses a reinforcement type rare earth electrolysis graphite crucible. The reinforcement type rare earth electrolysis graphite crucible structurally comprises a fixed plate, a cathodeadsorption rod, graphite, a graphite anode sheet, a fixed frame and a metal receiver. The cathode adsorption rod is provided with a cathode magnetic rod, a rotating device and a flowing mechanism. Rare earth irons are collected on the cathode adsorption rod, and therefore a liquid state is formed, the rare earth irons flow into the rotating device through the cathode magnetic rod and then fall onto the surface of a pressure plate, a rubber plate on a contraction mechanism bears force, the diameter of flowing holes is increased, the effect that rare earth liquid forms water drops at the momentof falling is achieved, resistance to liquid flowability is enhanced, and dispersion is avoided; by means of the bending degree of a sliding plate, rare earth liquid is prevented from splashing put in the rotating mechanism of a sliding mechanism, and therefore rare earth liquid is converged to a clearance between a ball and the sliding mechanism; and the sliding mechanism rotates through the ball under gravity of rare earth liquid, rare earth liquid flows through the ball in a gathered manner through steering force, and residues in the ball are avoided by means of steering force.

Description

technical field [0001] The invention relates to the field of graphene processing equipment, in particular to an enhanced rare earth electrolytic graphite crucible. Background technique [0002] The rare earth molten salt electrolysis process is the mainstream method for the production and preparation of rare earth metals. The electrolytic cell used is an open type. During electrolysis, a cathode rod is inserted in the middle of the crucible, and graphite anode sheets are hung around the crucible, thereby forming an electrode to generate an electric field and oxidation. After the rare earth is added to the graphite crucible, the high temperature and molten salt help to dissolve the oxidized rare earth, and the precipitated rare earth ions tend to the cathode to form a liquid by the action of the electric field. The rare earth droplets generated by the reaction are enriched on the cathode rod, and the rare earth droplets reach a certain weight. Falling from the bottom of the c...

[0002] The rare earth molten salt electrolysis process is the mainstream method for the production and preparation of rare earth metals. The electrolytic cell used is an open type. During electrolysis, a cathode rod is inserted in the middle of the crucible, and graphite anode sheets are hung around the crucible, thereby forming an electrode to generate an electric field and oxidation. After the rare earth is added to the graphite crucible, the high temperature and molten salt help to dissolve the oxidized rare earth, and the precipitated rare earth ions tend to the cathode to form a liquid by the action of the electric field. The rare earth droplets generated by the reaction are enriched on the cathode rod, and the rare earth droplets reach a certain weight. Falling from the bottom of the cathode rod to the metal receiver, the rare earth droplet is easily affected by the flow of the molten salt system itself during the process of falling from the cathode rod, and its falling track is prone to shift, and finally falls outside the metal receiver, which is different from other Impurities are mixed to form slag, which increases the difficulty of recovery and reduces the purity of metals
