AI Technical Summary

Technical Problem

The existing hot-dip galvanizing baths lack filtration functions, resulting in the galvanizing solution being contaminated by iron slag and impurities adhering to the metal surface, affecting the galvanizing quality and the finished product qualification rate.

Method used

The hot-dip galvanizing tank is designed with a filtration mechanism and a stirring mechanism. The filtration mechanism filters out iron impurities and other impurities in the galvanizing solution in a timely manner, while the stirring mechanism helps to settle impurities for more thorough filtration.

Benefits of technology

Ensure high purity of the zinc plating solution to improve the finished product qualification rate and guarantee that the zinc plating quality is not affected.

Abstract

The utility model relates to a kind of hot galvanizing tank based on galvanizing liquid, including bottom plate, hot galvanizing tank is placed in the bottom plate top end side, the side of hot galvanizing tank is provided with filtering mechanism, the filtering mechanism includes the first liquid pump of being set to the side of hot galvanizing tank, first connecting pipe is connected between the first liquid pump bottom and hot galvanizing tank, the second connecting pipe is set to the first liquid pump top, the second connecting pipe top is connected with filter box;By designing the device, when hot galvanizing tank is galvanized to metal, the galvanizing liquid in the inside can be filtered in time effectively after using a certain time, the iron impurities contained in the galvanizing liquid after use and other impurities are filtered, the purity is better when galvanizing liquid is used in later period, and the quality of metal galvanizing in later period is not affected, and the pass rate of finished product in later period is higher.
