AI Technical Summary

Problems solved by technology

The disadvantages of the existing rare earth alloy electrolysis production equipment are: 1. The electrolyte in the graphite electrolytic cell is static. During the electrolysis process, the back side of the graphite anode is prone to carbide slagging, so that the graphite anode can directly The voltage and current transmission to the graphite electrolytic cell, this part of the electric energy is a waste of no effect on the electrolytic reaction, so the energy consumption of the electrolytic reaction is large; 2. When the graphite anode directly transmits the voltage and current to the graphite electrolytic cell during the electrolysis process, The abnormal conversion of the cathode and anode of the graphite electrolytic cell leads to the abnormal production loss of the graphite electrolytic cell in the electrolytic production and increases the production cost; 3. Since the graphite anode will be continuously consumed during the electrolysis reaction, the distance between the graphite anode and the cathode 4. During the production process, the electrolyte is not fluid, so the temperature of the electrolyte in the graphite electrolytic cell cannot be uniform, and slagging is easy to occur
