Description

Technical Field

[0001] This utility model belongs to the technical field of electrolysis plate replacement devices, and specifically relates to an electrolysis plate replacement device for a vertical electrolysis cell. Background Technology

[0002] In the field of continuous galvanizing of metal strip, the cleanliness of the strip surface is a key prerequisite for determining the coating quality and product performance. If grease, iron oxide scale, or other contaminants are present on the strip surface, it will severely hinder the effective bonding between the zinc bath and the substrate, leading to reduced coating adhesion, defects such as missed plating spots, and ultimately affecting the corrosion resistance and service life of the product.

[0003] Therefore, modern galvanizing production lines generally employ electrolytic cleaning technology as a crucial pretreatment step before the steel strip enters the zinc bath. The core of this technology lies in utilizing electrochemical polarization: when the steel strip, acting as an electrode (anode or cathode), passes through the electrolytic cell, the surface charge distribution changes under the influence of current, effectively weakening the bond between contaminants and the base metal. Simultaneously, the electrolysis process continuously generates a large amount of gas (such as hydrogen or oxygen) on the steel strip surface. The escape of these gases creates a strong physical scouring effect on the steel strip surface (i.e., "gas washing"). This synergistic effect of electrochemical dissolution and physical stripping efficiently and thoroughly removes various contaminants and simultaneously optimizes the microstructure of the metal surface, creating a highly clean and activated surface for the subsequent galvanizing reaction.

[0004] However, the core consumable component of this electrolytic cleaning system—the electrolytic plate (anode or cathode plate)—inevitably undergoes electrochemical corrosion, wear, and deformation under harsh conditions of high current density and complex chemical media over long periods, and its performance gradually declines with prolonged operation. After a certain production cycle, the corrosion of the electrolytic plate severely impacts cleaning efficiency and uniformity, necessitating shutdown and replacement to ensure stable production line operation and product quality.

[0005] Currently, most galvanizing production lines adopt a vertical electrolytic cell structure, which has advantages such as small footprint and high compatibility with the strip steel direction. However, this very structural design brings huge maintenance challenges. To meet the production line's capacity and efficiency requirements, the electrolytic plates are usually designed to be large and heavy, making them impossible to move and accurately position manually.

[0006] In routine industrial equipment maintenance, the replacement of such heavy components typically relies on lifting equipment such as overhead cranes or gantry cranes. However, the unique characteristic of vertical electrolytic cells lies in the fact that their tops are often enclosed or equipped with dense pipelines, supports, and other devices. Due to structural limitations (such as the inability of the hook to descend vertically to the effective height inside the cell), overhead cranes and gantry cranes cannot extend their lifting arms deep into the cell, making it inconvenient to lift the heavy electrolytic plates to the designated installation location. Each disassembly and installation requires workers to perform lengthy work at height, and the operation process is difficult to standardize, posing certain safety risks.

[0007] Therefore, the industry is currently facing a dilemma regarding the replacement of electrolytic plates in vertical electrolytic cells: heavy-duty lifting machinery cannot be used, while relying solely on manual labor is insufficient. This results in extremely time-consuming replacement and maintenance work, immense labor intensity, safety hazards, and prolonged production line downtime, severely impacting production efficiency and operating costs.

[0008] In summary, there is an urgent need in this field for a dedicated electrolysis plate replacement device for vertical electrolytic cells that can overcome the aforementioned limitations, so as to achieve safe, efficient and convenient replacement operations, reduce downtime and lower maintenance costs.
