Description

A zinc liquid impurity filter equipment for hot dip galvanizing process Technical Field The utility model relates to the technical field of wastewater treatment of metal products, in particular to a zinc liquid impurity filtering device for a hot dip galvanizing process. Background In the hot dip zinc process, the zinc ingot itself used may contain some impurities, such as heavy metal impurities like iron, lead, copper, etc., as well as some nonmetallic inclusions. These impurities can enter the zinc liquid during the melting process of the zinc liquid, affecting the quality and performance of the zinc layer. For example, iron impurities can cause the zinc layer to appear dull, rough, etc., which reduces the corrosion resistance of the zinc layer. During the production process, in the production environment of hot dip zinc, the zinc liquid is in a high temperature state for a long time and can be contacted with surrounding air, equipment and the like, so that some impurities are generated. For example, zinc oxide is produced by oxidation of the zinc bath with oxygen in the air, and wear of the equipment during operation may cause some metal particles to fall into the zinc bath.
