Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-temperature electrolytic cell carbon plate fixing bolt removal, and in particular to a carbon plate fixing bolt removal device. BACKGROUND

[0002] In the operation process of a high-temperature electrolytic cell, the carbon plate plays a crucial role, as it not only participates in the electrochemical reaction as an electrode, but also bears the functions of supporting and conducting current. The fixing bolt is a key connecting piece that ensures the stable installation of the carbon plate in the electrolytic cell. However, the internal environment of the high-temperature electrolytic cell is extremely harsh, with high temperature and strong corrosion. Under such conditions, the fixing bolt is prone to corrosion. Over time, the degree of corrosion continues to increase, causing the connection between the fixing bolt and the carbon plate or the electrolytic cell body to become exceptionally tight, and even rusted and adhered.

[0003] When performing regular maintenance, repair, or component replacement on a high-temperature electrolytic cell, it is often necessary to remove the fixing bolt of the carbon plate. However, due to corrosion problems, traditional removal tools and methods often fail to work. For example, using a wrench or other conventional tools may slip due to severe corrosion on the surface of the bolt, failing to provide sufficient torque to loosen the bolt; using heating methods may cause thermal damage to other surrounding components in the complex environment of the high-temperature electrolytic cell, affecting the overall performance and safety of the equipment; chemical dissolution methods, although theoretically feasible, may introduce new chemicals in actual operation, adversely affecting other structures inside the electrolytic cell, and also have problems such as low dissolution efficiency and long processing time.
