Description
Technical Field
The cathode and crucible receiving structure of the invention belongs to an important component of an electrochemical instrument and is applied to high-temperature electrochemical production and manufacturing industries such as metallurgy, molten salt electrolysis preparation, molten salt electrolysis refining and the like. The method comprises the fields of ionic conduction, electrochemical inertia, good mechanical stability, electrode material selection, material contact, material collection, forming and the like.
Background
In the research of electrolytic refining technology, because the metal to be purified has extremely high chemical activity, the metal with chemical inertia is used as a cathode in order to avoid the chemical reaction between the metal and the cathode, and the metal is required to be easily assembled and disassembled on an electrolytic furnace; in addition, the material receiving crucible works in a high-temperature molten salt environment, and the requirement that the crucible has chemical inertia must be met.
The lower part of the tantalum pipe with good conductivity is selected as a metal collecting tank on the basis of considering high temperature resistance and molten salt corrosion resistance in the early stage, the effect is poor in the using process, and the tantalum pipe is processed into a perforated fan-shaped structure at the molten salt contact part later. Both of these cathodes have drawbacks. Firstly, the contact area is small, the current density is too large, the overpotential of the electrode is obviously reduced, and the enrichment of metal ions is influenced; secondly, the poor flowing property of the integrated metal beads on the tantalum tube causes the poor product collection and poor forming effect.
Therefore, it is necessary to use a cathode structure with a large surface area for the convenience of product enrichment and product separation of the cathode.
Disclosure of Invention
The invention aims to: the electrolytic refining furnace is simple in structure, resistant to corrosion of chlorine salt and fluorine salt, good in conductivity, convenient for metal cation enrichment, capable of enabling electrolytic refining to be normally carried out, and capable of obtaining a cathode product in a collecting crucible. The main functions of the electrolytic refining cathode structure are as follows: the cathode and the anode are conducted into a loop by conducting electricity in the molten salt, and the current density of the cathode is small due to the increased surface area of the cathode. The resulting metal beads can be smoothly dropped from the cathode into the collection crucible.
The technical scheme of the invention is as follows: a cathode and crucible receiving structure comprises a conducting rod, a magnesium oxide ceramic protection tube, a cathode contact surface and a receiving crucible, wherein the magnesium oxide ceramic protection tube is sleeved outside the conducting rod, the lower end of the conducting rod is connected with the cathode contact surface, and the cathode contact surface is positioned above the receiving crucible.
The conducting rod is provided with a thread structure.
The conducting rod, the magnesium oxide ceramic protecting tube and the cathode contact surface form a cathode.
The invention has the following remarkable effects: the novel electrolytic refining cathode structure can not only enable electrolytic refining to be carried out smoothly, but also enable generated metal beads to drip, and enable electrolytic reaction to occur rapidly in practical application.
