[0002] The zinc pot is a type of hot-dip galvanizing industrial equipment. Hot-dip galvanized products offer excellent corrosion resistance, superior mechanical properties, easy processing, and a long service life, finding application in a wide range of fields. Hot-dip galvanized products typically require the zinc bath to be continuously heated to maintain its molten state during daily use. However, during periods of maintenance and shutdown, the undisturbed zinc bath loses heat and forms zinc oxide, wasting both energy and liquid. This heat raises the production site temperature, particularly during hot summer months. Furthermore, maintenance work requires standing on an iron plate above the bath, where the high temperature of the bath's zinc bath significantly hinders smooth repairs and poses a safety hazard. Currently, the bath lacks insulation and protective devices when shut down, necessitating improvements. Utility Model Content
