Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal surface treatment technology, specifically, it relates to a hot-dip galvanizing tank. Background Technology
[0002] Hot-dip galvanizing is a common process for metal corrosion protection, which involves immersing steel components in molten zinc to form a zinc alloy coating.
[0003] Utility model CN221275858U discloses a hot-dip galvanizing tank for hot-dip galvanizing production, including a galvanizing tank base, a scraping mechanism above the galvanizing tank base, an adjusting mechanism for driving the scraping mechanism to move its position, and a lifting mechanism for raising the height of the scraping mechanism. The scraping mechanism and the adjusting mechanism are connected by a fixing member, and the scraping mechanism includes a horizontal rod. This utility model uses a scraping plate fixedly installed inside a scraping frame. The scraping frame and the scraping plate are inclined on the galvanizing tank base, allowing the adjusting mechanism to drive the scraping mechanism to move. This enables the scraping frame and scraping plate to effectively capture and push the zinc film. Furthermore, the connection between the scraping frame and the scraping plate is triangular, effectively preventing zinc film leakage during capture and pushing.
