Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum production, in particular to a continuous iron removal device for iron-containing materials in electrolytic aluminum. Background Art

[0002] Electrolytic aluminum is aluminum produced through electrolysis. Modern electrolytic aluminum production utilizes cryolite-alumina molten salt electrolysis. Molten cryolite serves as the solvent, alumina as the solute, carbonite as the anode, and molten aluminum as the cathode. A strong direct current is applied to the two electrodes within the electrolytic cell at temperatures between 950°C and 970°C, creating an electrochemical reaction known as electrolysis.

[0003] The surface of the anode steel claws used in electrolytic aluminum will oxidize due to the high temperature and a series of chemical reactions during the aluminum electrolysis process, forming a large amount of ferric oxide and ferric oxide. During the electrolyte cleaning process, the oxides on the surface of the anode steel claws are cleaned together with the electrolyte on the surface of the residual electrode. After the electrolyte is cleaned, it is crushed to form a powdery material with very small particle size. Therefore, a large amount of iron oxide is mixed with the electrode material, resulting in an excessively high iron content in the material. Utility Model Content

[0049] During use, the material is fed into the first magnetic adsorption unit through the vibrating feeding unit 100 for magnetic adsorption. After the material contacts the outer shell of the first magnetic roller 230 in the first reaction cylinder 220, the material sticks to the outer shell. As the internal magnet rotates, the outer shell generates or loses magnetic attraction, that is, as the internal magnet rotates, it adsorbs the material on the outer shell. After the adsorption is completed, the iron oxide is discharged through the first discharge pipe, and the purified material further enters the first reaction box 210. The air blowing pipe assists the material to enter the next stage for purification. After entering the second reaction box 310, the spring is driven up and down by the third driving member. The elastic action of the spring causes the material above it to shake, thereby increasing the contact between the material and the magnetic roller and increasing the adsorption effect. After the adsorption is completed, the purified material is extracted from the discharge port of the second reaction box 310, and the control device cuts off the power to the magnetic roller. The iron oxide adsorbed on it falls off and is extracted through the first discharge pipe, completing the purification of the material.
