Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing slag recovery, in particular to a hot-dip galvanizing slag recovery device. Background Art

[0002] Hot-dip galvanizing involves immersing derusted steel parts in molten zinc at approximately 500°C, depositing a zinc layer on the surface of the steel components. This provides corrosion protection and is an effective method for metal corrosion prevention. However, existing hot-dip galvanizing processes often produce zinc ash scum that can clog the filter screen during use.

[0003] In the prior art, a Chinese patent document with publication number CN118105755A has been proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a zinc ash recovery device for a hot-dip galvanizing process, comprising a connecting box, a filter screen is provided in the connecting box, and the right side of the filter screen extends outside the connecting box.

[0004] In order to solve the problem that zinc ash scum easily clogs the filter screen during use of the recovery device, the existing technology uses a filter screen to drive multiple triangular blocks to move left and right in a circular manner. However, there are still problems such as scum of different sizes, which cannot be completely filtered by a single filter screen, resulting in some fine scum passing through the filter holes and entering the bottom.
