Embodiment Construction
[0018] see figure 1 , figure 2 An anode carbon block 7 is arranged on the aluminum electrolytic cell 8, an anode guide rod 2 is arranged on the anode carbon block 7, an anode bus bar 1 is installed on the anode guide bar 2, and the anode bus bar 1 is connected to the column bus bar 4. A shielding tank cover plate 9 is set between the shell of the aluminum electrolytic cell 8 and the upper structure, and the shielding tank cover plate 9 connects the shell of the aluminum electrolytic cell 8 and the upper structure to form a closed magnetic shielding circuit. In the space surrounded by the magnetic material, the ferromagnetic material can be a steel plate or other magnetically permeable materials. The shielding groove cover plate 9 is mainly made of ferromagnetic material, and is composed of multiple pieces to form a whole. Each piece can be moved freely. It can be airtight or grid-shaped. Many pieces of ferromagnetic material can be moved to realize The normal operation of t...

Description
technical field [0001] The invention relates to an aluminum electrolytic cell, which belongs to the nonferrous metal smelting industry, in particular to a magnetically shielded aluminum electrolytic cell. Background technique [0002] Large-scale aluminum electrolytic cells are powered by a large-scale multi-point power supply method. Due to the strong current passing through the electrolytic cell, reaching hundreds of thousands of amperes, a strong magnetic field will be generated in the power supply bus, which will affect the electrolytic cell. The aluminum liquid that is the cathode and conducts a large current generates electromagnetic force, which makes the operation of the aluminum liquid layer unstable, thereby increasing the power consumption of electrolytic aluminum and reducing the current efficiency. At present, in order to reduce the influence of the magnetic field generated by the busbar on the molten aluminum, complex magnetic compensation measures are adopted....
