A material blocking device for covering material of aluminum electrolytic cell

Abstract

The invention discloses a material blocking device for covering materials of an aluminum electrolytic cell, which comprises a body, a tank casing is arranged inside the body, a horizontal fume hood is arranged on the upper side of the body, and a smoke hood is arranged on one side of the horizontal fume hood. The hood slot cover plate also includes an aluminum guide rod that runs through the horizontal fume hood plate, a base is fixedly connected to one end of the aluminum guide rod penetrating the horizontal fume hood plate, and an anode steel is fixedly connected to the other side of the base The claw is connected with an anode carbon block on the other side of the steel claw of the anode, and the upper right side and upper left side of the body are respectively arranged with a material blocking mechanism. In the present invention, the upper right side and the upper left side of the main body are respectively equipped with material blocking mechanisms, and they can move relative to the center of the anode carbon block according to the amount of loose electrolyte covering material, and finally form a regular covering material insulation layer .

Description

technical field [0001] The invention belongs to auxiliary equipment for the manufacture of aluminum electrolytic cells and the production of electrolytic aluminum, in particular to a covering material blocking device for aluminum electrolytic cells. Background technique [0002] In the production process of electrolytic aluminum in the aluminum electrolytic cell, the anode carbon block is continuously consumed due to the oxidation-reduction reaction. Therefore, the anode carbon block needs to be replaced in time. After the aluminum electrolytic cell is replaced with a new anode carbon block, in order to increase the temperature of the anode carbon block and prevent the oxidation of the anode carbon block, it is necessary to cover the anode carbon block with a loose electrolyte covering material for heat preservation. [0003] The existing general-purpose aluminum electrolytic cell is only equipped with a vertical vertical plate on the upper horizontal surface of the cell she...

AI Technical Summary

Problems solved by technology

[0003] The existing general-purpose aluminum electrolytic cell is only provided with a vertical vertical plate on the upper horizontal surface of the cell shell to properly block the loose electrolyte covering material, but , the barrier effect is very unsatisfactory, a large amount of electrolyte covering material flows out of the electrolytic cell, and at the same time, the amount of electrolyte covering material will eventually increase, and a regular covering material insulation layer will not be formed
