一种热镀锌用酸洗装置
By installing slots and partitions in the pickling tank, the hot-dip galvanizing pickling device solves the problem of traditional pickling tanks being unable to control the zones, enabling zoned pickling of workpieces with different degrees of corrosion, improving the pickling effect and reducing acid consumption.

AI Technical Summary
Traditional pickling tanks cannot achieve zoned control of acid parameters, resulting in the mixing of workpieces with different degrees of corrosion, which affects the adhesion of the galvanized layer.
A pickling device for hot-dip galvanizing was designed. The tank is equipped with three sets of slots and partitions. The partitions are installed by locking the slots, and the tank is divided into three independent pickling areas. The partitions are adjustable in position and can be disassembled to accommodate workpieces with different degrees of corrosion.
It enables zoned pickling of workpieces with different degrees of rust, avoiding over-pickling of lightly rusted workpieces or incomplete treatment of heavily rusted workpieces, and reducing acid consumption.
