Description

Technical Field

[0001] The utility model relates to the technical field of bolt pickling devices, in particular to a bolt pickling device. Background Art

[0002] After the bolts are rusted on the surface, they need to be derusted. Pickling is a commonly used method for bolt surface treatment. Specifically, acid solution is used to remove the oxide scale and rust on the steel surface. In the preparation process of the bolts, the surface quality obtained by pickling directly determines the subsequent process difficulty of the bolts. The pickling treatment of the bolts requires the use of special pickling equipment.

[0003] After the bolts are extracted after pickling in the existing bolt pickling device, sticky pickling liquid will remain on the bolts. Generally, it takes a long time to drain water inside the pickling device to remove most of the pickling liquid, which wastes a lot of time and affects the efficiency of the pickling operation. If the screws are extracted without draining water, first, the pickling liquid will drip and be wasted, and second, the pickling liquid will drip and corrode other equipment or tools.
