Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolytic cells, in particular to a pole-changing shell-breaking hammer rotary device for an aluminum electrolytic cell. Background Art

[0002] The core equipment of industrial aluminum smelting is the aluminum electrolysis cell. During the operation of the aluminum electrolysis cell, the service life of the anode carbon block with a guide rod is limited. When the carbon block is exhausted during the electrolysis process, the anode needs to be replaced by an overhead crane. During the aluminum electrolysis process, the anode is covered with a hard alumina crust due to the high temperature and the covering of insulating alumina powder. Therefore, the crust needs to be broken to pull out the anode, which is usually called the shelling operation.

[0003] The current shelling hammers have different forms, which are basically divided into stick type and axe type. The axe type hammer can perform shelling operations on a larger area of crust, and its efficiency is higher than that of the traditional stick type hammer, with fewer broken pieces. However, the axe type hammer needs to be rotated 90 degrees when switching from the horizontal side to the vertical side. Since the axe type hammer arranges the motor, reducer and other equipment on the hammer head, its volume is too bloated compared to the stick type. The space around the electrolytic cell is small, and there is a hidden danger of collision with the equipment. In addition, the hammer head is too heavy, the center of gravity is biased towards the hammer head, and the load on the rear-end control motor is too large, affecting normal use.
