Novel anode carbon block for continuous prebaking

Abstract

The invention provides a novel anode carbon block for continuous prebaking. The novel anode carbon block is characterized in that a carbon bowl is arranged at the top of a carbon block body; a carbon bowl filling block is movably arranged in the carbon bowl; a bump is arranged on the top surface of the carbon block body; a groove is formed in the bottom surface of the carbon block body and corresponds to the bump; a plurality of protrusions are arranged on one side face of the bump and distributed in the length direction of the bump, a plurality of recesses are formed in one side wall of the groove and distributed in the depth direction of the groove, the protrusions are matched with the recesses, and the distribution directions of the protrusions and the recesses are consistent, so that after the bump is inserted into the groove and the protrusions and the recesses are embedded in a one-to-one correspondence mode, the new carbon block body is connected with the old carbon block body. The continuous use of a prebaked anode is realized, the time for connecting new anode carbon block is short, the labor intensity is low, the use is convenient, the bonding area of the new and old carbon blocks is increased, the connection strength of the carbon blocks is improved, the service life of a single carbon block is prolonged, the production cost is low, the production efficiency is improved, and the product percent of pass is improved.

Description

technical field [0001] The invention relates to the technical field of prebaked anode carbon blocks for aluminum electrolytic cells, in particular to a novel anode carbon block for continuous prebaking. Background technique [0002] Anode carbon block refers to the carbon block produced with petroleum coke and pitch coke as aggregate and coal tar pitch as binder, which is used as anode material for prebaked aluminum electrolytic cell. This kind of carbon block has been roasted and has a stable geometric shape, so it is also called prebaked anode carbon block, and it is also called carbon anode for aluminum electrolysis. [0003] At present, when the prebaked anode carbon block is replaced, the surrounding insulation material must first be knocked off, and then the guide rod, steel claw, and anode residue assembly must be pulled out. When the old carbon block is removed, a lot of heat will be taken away, and the electrolyte will be directly exposed, which also leads to a lot...

AI Technical Summary

Problems solved by technology

When the old carbon block is removed, a lot of heat will be taken away, and the electrolyte will be exposed directly, resulting in a lot of waste of heat energy

After the new carbon block is directly inserted, it will absorb a lot of heat energy. The electrolyte condensed on the surface of the new carbon block will make the new carbon block non-conductive. It usually takes about a day for the new carbon block to continue to work normally, resulting in high production costs.
