Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing tank ash scraping devices, and specifically relates to an ash scraping device for a galvanizing tank. Background Technique

[0002] During the use of metal workpieces, they are prone to oxidation, corrosion, etc. Especially in humid, acidic or alkaline environments, corrosion is more likely to occur. Therefore, in the processing field, some workpieces need to be galvanized in a galvanizing tank. By galvanizing, a zinc layer can be formed on the surface of the workpiece, effectively blocking the erosion of the external environment on the metal, thereby improving the corrosion resistance of the workpiece and extending the service life of the workpiece. Moreover, the surface of the galvanized workpiece has a silver-white luster, making it more beautiful in appearance and suitable for some occasions with high appearance requirements, such as the fields of architecture and furniture. When the zinc liquid or zinc vapor contacts the surface of the workpiece during galvanizing in the galvanizing tank, if there are grease, dirt or other impurities on the surface of the workpiece, these impurities may react with the zinc liquid during galvanizing to produce zinc ash. Zinc ash usually deposits in the galvanizing tank or floats on the surface of the zinc liquid. To ensure the stability and effect of the galvanizing process, the zinc ash needs to be removed. However, zinc ash not only floats on the surface of the zinc liquid, but also deposits at the bottom of the galvanizing tank and adheres to the side walls of the galvanizing tank. Existing zinc ash scraping devices cannot filter the zinc liquid, resulting in the inevitable removal of some zinc liquid together with the zinc ash during the cleaning process. Therefore, those skilled in the art have provided an ash scraping device for a galvanizing tank to solve the problems raised in the above background technique. Content of the Utility Model

[0003] The purpose of the utility model is to provide an ash scraping device for a galvanizing tank to solve the problems raised in the above background technique.
