[0002] The aluminum electrolysis industry is an important basic industry of modern industry and occupies a key position in the national economy. During the production process of aluminum electrolysis, a large amount of carbon slag is generated in the electrolytic cell. If these carbon slags are not cleaned in time, it will not only affect the current efficiency of the electrolytic cell, increase energy consumption, but also may erode the inner lining of the electrolytic cell and shorten the service life of the equipment.

[0003] In the prior art, generally, a slag scraping hopper is used to fish out the carbon slag. However, during the slag scraping process of the slag scraping hopper, generally, after the two slag scraping hoppers are placed in the electrolytic cell by the work of the overhead crane, the slag scraping is achieved by changing the angle of the slag scraping hopper. However, during the process of the angle deviation of the slag scraping hopper, the bottom end of the slag scraping hopper makes an arc-shaped movement, so it is easy to generate a slag scraping dead angle at the bottom end position of the electrolytic cell, thereby affecting the slag scraping effect.
