Description

Technical Field

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

[0002] During the processing of workpieces or after long-term idling, oxidation will occur on the surface of the workpieces. In order to improve the appearance and corrosion resistance of the workpieces, the workpieces need to be pickled and passivated, so pickling devices are required.

[0003] After retrieval, it is found that the Chinese utility model patent with the authorization publication number of CN218812107U discloses a high-performance stainless steel pickling equipment. From its specification, it can be known that after the pickling and passivation treatment of stainless steel workpieces is completed, the first motor is turned on to make the pickling basket on the connecting plate flip through the first rotating rod. When the pickling basket flips to a certain angle, the stainless steel workpieces inside fall into the cleaning basket by their own weight. Then the water pump is turned on to pump water from the water tank, and then the water pump sprays the water from the high-pressure spray through the water pipe and the water outlet pipe to wash the surface of the stainless steel workpieces.

[0004] However, during the flipping process of the pickling basket, when the workpieces fall into the cleaning basket through the pickling basket, collisions will occur between the workpieces during the falling process, resulting in damage to the workpieces; moreover, after the cleaning is completed, the cleaning water cannot be recycled but is directly discharged, causing waste.
