Abstract
A cathode structure for electrolytic refining includes a cathode surface portion having a circular ring shape and having holes formed therein; the cathode surface portion is connected with the clamping rod. The cathode structure material for electrolytic refining is tantalum.
Description
Technical Field
The invention relates to a cathode structure, in particular to a cathode structure for electrolytic refining.
Background
In the research of electrolytic refining technology, the electrolytic refining parts are high temperature resistant, chlorine salt resistant, fluorine salt resistant, stable and durable work of materials, high current efficiency, low overpotential, good conductivity and good ion enrichment. In the early stage, a tantalum pipe with good conductivity is selected on the basis of considering high temperature resistance and molten salt corrosion resistance, holes are formed in the part in contact with molten salt in the using process, but the test effect is not obvious, and then the tantalum pipe is processed into a fan-shaped structure with the holes in the molten salt contact part. Both of these cathodes have drawbacks. Firstly, the contact area is small, and the metal ions after migration are not easy to enrich due to overlarge current density; secondly, poor product collection and poor forming effect.
In order to enable the electrolytic refining process to be smoothly carried out, an electrolytic refining cathode structure which is simple in structure, resistant to molten salt corrosion, good in electric conductivity, large in contact area, good in ion enrichment and good in collection effect needs to be designed.
Disclosure of Invention
The invention aims to: the design one kind simple structure, resistant chlorine salt, villiaumite corruption, electric conductive property are good, and the metal cation of being convenient for takes place reduction reaction at surface deposition, can make the electrorefining normally go on, and the electrorefining cathode structure mainly is the integrated process who realizes the electrolysis in-process stirring and electrolysis positive pole, adopts such electrode connection mode, has simplified the device in the testing process and has connected, and the experimental effective of being convenient for goes on. The contact area of the electrolytic refining product is large enough, and the electrolytic refining yield can be guaranteed.
The technical scheme of the invention is as follows: a cathode structure for electrolytic refining includes a cathode surface portion having a circular ring shape and having holes formed therein; the cathode surface portion is connected with the clamping rod.
The cathode structure material for electrolytic refining is tantalum.
The cathode surface portion is connected to the clamping rod by a nut.
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 metal ions to be enriched quickly, and enable electrolytic reaction to occur rapidly in practical application.
