Description

Guide rod righting device and loading and unloading station

Technical Field

The utility model relates to an electrolytic aluminum equipment structure, in particular to a guide rod righting device and a loading and unloading station.

Background

In the electrolytic aluminum smelting process, a carbon anode connected to an anode guide rod group is generally immersed into an electrolytic tank filled with molten electrolyte, and under the action of an electric field between the carbon anode and a cathode at the bottom of the electrolytic tank, carbon elements in the carbon anode react with alumina molten in the electrolyte to generate carbon dioxide, so that aluminum ions in the alumina are reduced into elemental aluminum, and the preparation of the raw aluminum is completed. In this electrolysis process, the carbon anode is consumed continuously, and the anode becomes a anode scrap after about 30 days of consumption, so that it is necessary to replace the anode with a new one. The anode scrap is sent to an anode assembly shop for treatment. The char is recovered and the anode guide group needs to be treated to produce the anode group. The anode scrap group to be treated needs to be loaded onto a catenary system and processed by an anode assembly equipment production line, and in addition, the assembled anode scrap group needs to be unloaded from the catenary system to an anode tray and transported to an electrolysis plant by an anode trailer. The efficiency with which the anode scrap sets are loaded into and unloaded from the catenary affects the efficiency of the overall anode assembly plant. Therefore, how to improve the loading and unloading efficiency of the anode and anode assemblies on the catenary system becomes a problem to be solved.
