Background
In the production process of the prebaked cell, the replacement of the anode is an indispensable operation, and after the replacement of a new anode carbon block, an anode covering material with a certain thickness needs to be additionally sealed on the upper surface of the anode so as to preserve the heat of the anode carbon block, avoid the oxidation of the anode carbon block and improve the conductivity of the anode carbon block.
The current working method for the anode covering material during pole changing is as follows: firstly, using tools such as an aluminum rake and the like to rake out covering materials on the anode to be replaced and on the edge part of the anode in a fan shape, raking the raked-out covering materials on the inner side of a groove edge plate or shoveling the raked-out covering materials on the adjacent anode, then taking out and lifting the anode scrap to replace the anode scrap with a new anode; after the new carbon anode is replaced, the heat-insulating covering material is manually loaded on the upper part of the anode carbon block by one shovel, or a hopper loaded with the covering material is hoisted to the front of an electrolytic tank by a crown block, the covering material of the artificial auxiliary part is dumped in the electrolytic tank, and then the covering material is spread and shaped to keep the natural inclination. And covering alumina with a certain thickness (14-18 cm) after the new electrode is installed, so that the anodic oxidation is prevented, the upper heat preservation of the electrolytic cell is enhanced, the temperature of a steel-carbon contact part is rapidly increased, and the contact voltage drop is reduced. Therefore, the operation work efficiency is low, the labor intensity of workers is high, and the phenomenon of adsorption is easy to occur under the strong magnetic field environment of the electrolytic cell due to the fact that the hopper is made of steel materials and is used for adding, and the cover materials are easy to scatter uncontrollably in the hoisting process and damage the workshop environment due to incomplete dumping. Meanwhile, when the anode is replaced, a large amount of covering materials stay on the anode, and the covering materials in the anode replacement hoisting and transporting process scatter and fly in a workshop, so that the covering materials are lost, and the workshop environment is influenced to a certain extent.
The anode scrap and the surrounding covering materials are manually cleaned, and the following problems exist:
the mechanization degree is low, the labor intensity of workers is high, the covering material on the anode scrap is not completely cleaned, and a large amount of residue exists;
when the anode scrap is taken out, covering materials remained on the anode scrap or around the anode scrap are easy to drop into the electrolytic bath, so that the secondary cleaning is achieved manually, and meanwhile, the stability of the electrolytic bath is also influenced;
in the hoisting process of the anode scrap, a large amount of residual covering materials on the anode scrap are scattered along the way, so that the influence on the environment is great, and the workshop operation environment is deteriorated;
patent CN201120520691.X provides a covering material box for covering a prebaked anode of an aluminum electrolytic cell, which overcomes the defects that the working environment is severe, the labor intensity is high, the covering material is scattered and raised when the anode is replaced manually in the prior art, the material loss, the pollution, the heat energy waste and the like are caused; the covering materials cannot be collected and temporarily stored, the covering materials are added into the electrolytic cell for operation, in addition, the operation needs manpower, crown blocks and the like, and the automation is low.
Patent CN201410308147.7 proposes a material blocking device for covering material of aluminum electrolytic cell, which is based on the principle of reducing the consumption of bulk covering material of electrolyte under the condition of forming a regular insulating layer of covering material. Patent CN201620501366.1 proposes a high-temperature pneumatic conveying device for granular materials, in which the power is a fan and the power source is electricity.
With the rapid development of the Chinese industry, the issue of the national academy of China Intelligent manufacturing 2025, the improvement of the industrial automation level requirements of enterprises, and the realization of automatic operation, environmental protection cleaning and collection of covering materials on anode scrap during the anode replacement operation are completely necessary. The adoption of an intelligent and environment-friendly processing mode for pole changing is an important research and development direction.
