Description

Technical Field

[0001] The utility model relates to the technical field of electrolysis equipment, in particular to an anode positioning device for an aluminum electrolysis unit. Background Art

[0002] During the electrolysis process, the carbon anode will be slowly corroded by the electrolyte, causing the carbon anode to gradually decrease. When it decreases to a certain extent, the carbon anode needs to be replaced.

[0003] However, due to the large area of ​​the electrolytic cell, in order to facilitate the replacement of the carbon anode, the carbon anode is generally hung on the edge of the electrolytic cell. Although this method is convenient for replacement, the area of ​​contact with the electrolyte is relatively small.

[0004] For example, an aluminum electrolytic anode replacement and positioning device disclosed in announcement number CN220012840U is provided with an adjustment component. This design allows the carbon anode to be positioned inside the electrolytic cell through the clamp component. Then, the movable block is moved left and right by rotating the screw until the clamp component moves to the center of the electrolytic cell. In this way, on the basis of convenient replacement of the carbon anode, the position of the carbon anode inside the electrolytic cell is also conveniently replaced, so that the electrolytic cell is in better contact with the electrolyte. The positioning component is provided. This design allows the top frame to be placed on the top of the electrolytic cell during use, and then the knob at the end of the screw is held and rotated so that the inner side of the positioning piece and the outer side of the electrolytic cell fit together, thereby positioning the top frame at the top of the electrolytic cell to ensure stable use.

[0005] However, when the device is used, the anode is not positioned when it is installed at the center of the electrolytic cell, resulting in a deviation in the installation position of the anode, which affects the amount of electrolyte.

[0006] For this reason, we urgently need to provide an anode positioning device for an aluminum electrolysis unit. Utility Model Content

By turning the knob, the threaded rod is threadedly connected to the moving block, so that the moving block moves with the anode below.
