Description

Technical Field

[0001] The utility model relates to the field of electrolytic aluminum production equipment, in particular to a residual electrode bottom cleaning device. Background Art

[0002] In the process of electrolytic aluminum production, anode carbon blocks, alumina and cathode carbon blocks are used as anodes, electrolytes and cathodes respectively. As a conductor and participating in electrochemical reactions, the anode contains high electrolyte components such as aluminum, sodium, potassium, calcium, magnesium, lithium, fluorine and other components due to long-term contact with the electrolyte. The surface is often covered with a hard shell formed by the electrolyte, forming bag-shaped or cone-shaped protrusions, which affect the conductivity of the anode and increase power consumption. Moreover, these electrolytes will form a large amount of ash after the residual anode is returned to the pre-baked anode production. The elements in the impurities of the residual anode ash that play a catalytic role will increase the selective oxidation of the pre-baked anode in the electrolytic cell, which is very likely to cause the anode to slag, seriously affecting various indicators of aluminum electrolysis. The use of residual anodes can effectively reduce the cost of anodes, but the premise is that the quality of residual anode cleaning must be ensured.

[0003] When cleaning the anode butts, it was found that the difficulty of cleaning is mainly concentrated on the bottom of the anode butts. The traditional method of cleaning the bottom of the anode butts is to remove the anode butt carbon blocks from the electrolytic cell, and then manually knock or polish them clean before returning them for continued use. This method is difficult to clean and the high temperature is harmful to human health. It is time-consuming and labor-intensive, and the cleaning efficiency is low. At present, the bottom of the anode butts is mostly cleaned by swinging chains or fixed steel brushes, but there are also some disadvantages in the chain-swinging operation. If the chain is too short, the bottom of the anode butts cannot be cleaned. If the chain is too long, the bottom of the anode butts will be overstressed, causing the thin anode butts to break and there will be a lot of dust on site. When using a fixed steel brush to clean the bottom of the anode butts, due to the irregular thickness of the anode butts, the steel brush will not contact the bottom of the anode butts when the anode butts are thin, and it cannot be cleaned. When the anode butts are too thick, the anode butts squeeze the steel brush for a long time, causing the steel brush to be severely deformed. Frequent replacement of steel brushes is time-consuming and labor-intensive, with high costs and high labor intensity, resulting in low cleaning efficiency and poor cleaning effect. Utility Model Content
