[0002] In the production process of anchor cable, pickling is a crucial link. As a key component in the fields of civil engineering, bridge construction, mine support, etc., the surface quality of anchor cable directly affects its service life and safety. The main purpose of pickling is to remove the oxide scale, rust and other impurities on the surface of anchor cable to form an ideal surface state, providing a good foundation for subsequent processing such as galvanizing, painting, etc.

[0003] In the traditional pickling process, the traditional pickling tank design often tends to be a deep acid liquid pool. Although this layout simplifies the storage and circulation system of acid liquid to some extent, the deep tank body has quietly buried several challenges, significantly affecting production efficiency and cost effectiveness. Due to the deep depth of acid liquid, the upper and side parts of anchor cable are often difficult to fully expose to acid liquid when passing through the acid liquid, resulting in incomplete removal of oxides, rust and other impurities in these critical parts. This limited contact area not only limits the pickling effect, but also makes a large amount of acid liquid unable to exert its full decontamination capacity, directly reducing the utilization rate of acid liquid. With the passage of time, enterprises need to continuously supplement new acid liquid to maintain the necessary cleaning effect, which undoubtedly increases the use and disposal cost of acid liquid.
