Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis, in particular to a novel shell-breaking hammer head. Background Art

[0002] The electrolytic cell is unloaded through several unloading holes set at the center seam, and unloading is carried out every tens of seconds. Due to the effect of high-temperature sintering, the alumina at the unloading hole is easily sintered to form a harder shell surface to seal the unloading hole, thereby hindering the smooth entry of alumina into the electrolyte during unloading. The current electrolytic cell is equipped with a shelling cylinder at the corresponding position of each unloading hole. The lower end of the cylinder is equipped with a cylindrical shelling hammer head. Before each unloading, the shell is broken once to pierce the unloading hole to ensure that the alumina can smoothly enter the electrolyte during unloading. The shelling hammer head is generally composed of three parts: a hammer head, a hammer rod, and an end shaft. The hammer rod and hammer head of the traditional shelling hammer head are welded from steel pipes and round steels of the same diameter.

[0003] During long-term shelling operations, the hammer head is gradually corroded and consumed by the electrolytic solution, becoming shorter and shorter. When it cannot reach the electrolytic solution, the hammer head needs to be replaced. Every time a traditional shelling hammer head is replaced, the entire cylinder and hammer rod need to be hung down from the tank, and then hung up and installed again after replacement. The operation is cumbersome, time-consuming, labor-intensive, and inefficient. Utility Model Content
