Abstract

The invention discloses an aluminum electrolytic cell. The aluminum electrolytic cell mainly comprises a cell body, a single polar-plate cathode and a single polar-plate anode. The cell body is of cavity structure, the single polar-plate cathode and the single polar-plate anode are arranged at a power inlet end and a power outlet end inside the cavity of the cell body respectively, the single polar-plate cathode is electrically connected with a power source cathode, and the single polar-plate anode is electrically connected with a power source anode. Electrolyte is filled between the single polar-plate cathode and the single polar-plate anode, and liquid aluminum is filled below the electrolyte. Compared with the prior art, the aluminum electrolytic cell has the advantages that cell voltage is stepped down by about 0.8V, and about 2400kwh of power can be saved per ton of aluminum.

Description

technical field [0001] The invention relates to an aluminum electrolytic cell. Background technique [0002] The electrolytic cell of the prior art is mainly composed of a cell body, an anode, a cathode, and a connecting bus bar. The cell body is composed of a steel shell and various materials such as heat preservation, refractory, carbon, and filling; the anode is composed of a guide rod group, phosphorus pig iron, and an anode The cathode is assembled from carbon blocks; the cathode is assembled into a cathode carbon block group by cathode steel rods, cathode carbon blocks, and cathode paste, and then constructed in the tank; the connecting busbar is composed of anode horizontal busbars, column busbars, cathode busbars, and various connection soft bars. In order to reduce the influence of the complex electromagnetic field on the electrolytic cell, the structure of the cathode bus bar is relatively complicated; therefore, the entire electrolytic cell is bulky and complex in...
