Description

Technical Field

[0001] The utility model relates to the technical field of iron accessory processing, in particular to a hot-dip galvanizing device for electric iron accessories. Background Art

[0002] Hot-dip galvanizing involves first pickling steel parts to remove iron oxide from the surface. After pickling, the parts are then cleaned in an aqueous solution of ammonium chloride, zinc chloride, or a mixture of ammonium chloride and zinc chloride before being placed in a hot-dip galvanizing tank. Iron accessories require hot-dip galvanizing during processing to achieve corrosion protection.

[0003] Utility model application number CN202321844141.2 discloses a hot-dip galvanizing device for electrical iron accessories. The device comprises a circular plate, a slide plate, bolts, a housing, a chute, a positioning pin, a nut, and a collection plate. A sliding rod rotates on the outer wall of the circular plate, driving the collection plate and a frame directly below the hook through the housing. Liquid on the surface of the iron accessory drips onto the collection plate. During the lifting and movement of the iron accessory, the collection plate with a frame collects the zinc liquid, preventing it from dripping.

[0004] The above device collects the zinc liquid through the collecting plate, and cannot directly flow the zinc liquid back into the galvanizing tank. The zinc liquid cools and solidifies on the collecting plate, and it is inconvenient to remove the zinc liquid from the collecting plate, which easily causes waste of zinc liquid. After the galvanizing is completed, it is necessary to wait for the zinc liquid to cool down, then remove the iron accessories from the hook, and then hang the iron accessories that need to be galvanized on the hook, which takes a long time and cannot be continuously hot-dip galvanizing operation, thereby reducing the efficiency of hot-dip galvanizing.

[0005] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content
