Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic aluminum, and specifically to a novel rotatable crust-breaking mechanism. Background Art

[0002] The crust-breaking device of the electrolytic aluminum cell is a key device in the production process of electrolytic aluminum. During the production process, a hard crust layer will form on the surface of the molten electrolyte at about 910 - 970 °C in the electrolytic cell. It is necessary to break through this crust surface through the crust-breaking device so as to add alumina raw materials to continue the electrolytic production. The crust-breaking device controls the hammer head to move downward through a cylinder to break through the hard crust on the surface of the electrolyte and form a feeding channel.

[0003] Most of the existing technologies use a hammer head and a shovel head for crust breaking. The hitting area of the hammer head is small, so the efficiency is low. The hitting area of the shovel head is large, but it is easy to have interference when hitting the corner. Therefore, whether the rotation of the shovel head can be reasonably controlled during the crust-breaking process is a problem to be solved today. Summary of the Invention
