Description

Technical Field

[0001] The utility model relates to a safety device for preventing leakage in aluminum electrolysis production, in particular to an insulating structure of a steel column of an operating platform of an aluminum electrolysis workshop. Background Art

[0002] During the electrolytic aluminum production process, a plurality of electrolytic cells are arranged in a steel structure plant, wherein the steel structure plant includes a plurality of steel columns and a ceiling fixed on the top of the steel columns.

[0003] In the production of electrolytic aluminum, the workshop operating platform is an important structure. Operators need to perform corresponding operations on the workshop operating platform, which is fixed on the pillars. The problem with the existing technology is that each electrolytic cell is connected in series with a large current, and the parts above the workshop operating platform are mostly steel components, such as the steel pillars on the upper side of the workshop operating platform. When multiple electrolytic cells are connected in series, if leakage occurs, it may cause a short circuit to the electrolytic cell operating platform. In addition, the pillars above the workshop operating platform are all steel pillars, which makes electric shock accidents particularly prone to occur.

[0004] In the prior art, in order to avoid electric shock accidents caused by leakage of electricity in steel columns, brick walls are usually built around the steel columns to achieve external insulation of the steel columns. Specifically, a circle of brick walls is built around the steel columns on the workshop operating platform, and then the brick walls are painted. This method of insulating steel columns by building brick walls is too cumbersome, the load of the brick walls is heavy, and the structural columns and beams need to be cast on site to tie the steel columns together, which makes the construction very inconvenient. In addition, the floor load of the workshop operating platform increases, and the work of painting the surface will also increase the workload. In addition, the wall is not resistant to high temperatures. After a long time, the wall paint layer is easy to fall off, and cracks may occur. Once cracks appear in the wall, the insulation effect will be greatly weakened. Utility Model Content
