Embodiment

[0020] Such as figure 2 with image 3 As shown, the flat-bottomed carbon bowl anode for aluminum of the present invention includes several carbon bowls 10 arranged on the anode, the inner side of the carbon bowl 10 is provided with a spiral groove 11, and the top of the spiral groove 11 is connected with the top of the carbon bowl 10. flush, the bottom of the spiral groove 11 and the bottom 12 of the charcoal bowl 10 are on the same level.

[0021] In this embodiment, the charcoal bowl part 10 is further provided with a charcoal bowl cover 20, and the charcoal bowl cover 21 is provided with a through hole (not shown in the figure) through which the steel claw 1 passes.

[0022] In this embodiment, the inner diameter of the carbon bowl 10 is slightly larger than the outer diameter of the steel claw 1 .

[0023] In this embodiment, the spiral groove 11 is connected and fixed to the steel claw 1 through the ferrophosphorus 2 .

[0024] In the flat-bottomed carbon bowl anode f...

Abstract

The invention aims to discloses a flat carbon bowl anode for aluminum. The flat carbon bowl anode for the aluminum comprises a plurality of carbon bowl parts arranged on the anode. The inner side of each carbon bowl part is provided with a spiral groove, wherein the top of the spiral groove is flush to the top of the carbon bowl part, and the bottom of the spiral groove and the bottom of the carbon bowl part are located on the same horizontal plane. Compared with the prior art, due to the fact that bosses on the bottoms of the carbon bowls are removed, contact voltage drop of the anode and steel claws is reduced, the bottom thickness of ferro-phosphorus is reduced, and pressing dropping of the ferro-phosphorus is facilitated; and when the flat carbon bowl anode for the aluminum is used onan electrolytic cell, electrode dropping, bottom penetrating and claw smelting faults cannot be caused to the anode, the aluminum electrolysis production cost can be greatly reduced, and the purpose of the flat carbon bowl anode for the aluminum is achieved.

Description

technical field [0001] The invention relates to a carbon anode, in particular to a flat-bottomed carbon bowl anode for aluminum. Background technique [0002] Carbon anode for aluminum electrolysis refers to the carbonaceous electrode connected to the positive electrode of the power supply in the aluminum electrolysis cell, which is an important part of the aluminum electrolysis cell. The prebaked anode of the aluminum electrolytic cell is composed of multiple anode carbon block groups, and each anode carbon block group consists of 1-2 anode carbon blocks with a width of 700-900mm, a length of 1400-1700mm, and a height of 500-600mm, anode guide rods and steel Claws and other parts. The carbon anode for aluminum is used in the anode of the aluminum electrolytic cell, which leads the current into the electrolytic cell and participates in the electrochemical reaction. During the aluminum electrolysis process, the average daily consumption of the carbon anode is about 2 cm, an...
