Rare earth electrolytic cell is the main equipment for producing rare earth metal.Currently,most of electrolytic cells on the market tend to be miniaturized,and they have many disadvantages,such as scattered distribution,low electrolytic efficiency,and large manpower required,which are not suitable for large-scale production needs of enterprises.In view of this situation,a rare earth electrolysis cell,namely 10 KA rare earth electrolysis,which has high electrolysis efficiency and large output and is suitable for large-scale production by enterprises,is designed to solve the shortcomings of the above-mentioned small electrolysis cell.Specific work contents are as follows:Study the 10 KA rare earth electrolytic trough type according to design requirements,determine the structural shape of the electrolytic,calculate the initial cathode,anode and other electrolytic structural parameters,use UG software to establish three-dimensional model diagram of various parts of the electrolytic Completed the establishment of the entire model.Calculate the parameters of the 3D flow field of the 10 KA rare-earth electrolytic cell before solving the calculation,establish a mathematical model of the three-dimensional flow field of the electrolytic cell,and use fluid simulation software FLUENT to three-dimensional flow field of the electrolytic cell.The simulation analysis was conducted to study the formation process of anode bubbles in the electrolytic cell,the rising diffusion motion in the electrolyte,and the velocity and distribution of the gas phase.The formation of vortex flow in the electrolyte cycle,the velocity of the electrolyte,and the movement of the gas bubbles to the electrolyte were studied.The effect of the three-dimensional flow field at different transverse pole pitches and different longitudinal pole pitches of the 10 KA rare-earth electrolytic cell was simulated and analyzed.Finally,the best value of the optimal lateral pitch and longitudinal pitch of the electrolytic cell was obtained.The mathematical model of the three-dimensional electric field of the 10 KA rare earth electrolytic was established,and the three-dimensional electric field of the 10 KA rare earth electrolytic was simulated and analyzed using COMSOL software.The distribution area of the electric field in the electrolytic cell was obtained: graphite anode area,tungsten cathode area,Intermediate electrolysis zone and bottom metal collector zone.In the middle electrolysis area,the potential lines are dense,the anode potential is high,the cathode potential is low,the current flows from the anode to the cathode,the collector wire in the region of the collector is sparse and the potential is low,which is conducive to the collection of rare earth metal elements;10KA rare earth electrolysis is studied.The effects of different cathode diameters and different depths of cathode insertion on the three-dimensional electric field,and the target cell voltage and current density,yielded the best cathode diameter and cathode insertion depth.Development and design of 10 KA rare earth electrolytic furnace cover plates,inner and outer protective sleeves,corundum gaskets,etc.,research on the selection of heat-insulating materials and refractory materials,and the assembly of all parts and electrolytic in the workshop.The drawings were CAD drawings.Finally,the installation and manufacturing process of the rare earth electrolytic cell was briefly described. |
