Technical Field
[0001] The utility model relates to the technical field of metal galvanizing, in particular to a pickling and stirring device for metal parts before galvanizing. Background Art
[0002] Galvanizing is a surface treatment method for metals. Galvanizing is the process of adding a zinc coating to the surface of steel or iron. Since zinc acts as a sacrificial coating, it protects the steel or iron underneath. Galvanized metal can have stronger rust resistance and corrosion resistance, thus extending the service life of metal parts. Metal parts need to be pickled before galvanizing. Pickling is a method of using an acid solution to remove oxide scale and rust on the surface of steel. It is a way to clean the metal surface. Pickling can make the subsequent zinc layer adsorb more firmly to prevent the zinc layer from falling off at the same time as the iron oxide. When pickling, metal parts are generally placed in a pickling tank and then stirred by a stirring device to make the parts fully contact with the pickling solution.
[0003] During the pickling process, the oxide scale and rust on the surface of the metal parts will be cleaned off the metal surface. The cleaned oxide scale and rust will accumulate in the pickling tank, which is difficult to clean and causes inconvenience to subsequent use. Utility Model Content
