Abstract
This invention discloses an electromagnetic purification and iron removal device for hot-dip galvanizing, relating to the field of hot-dip galvanizing technology. The device includes a front-end treatment chamber, a rear-end treatment chamber, electromagnetic rods, a front cover, a mesh cylinder, and electromagnetic blocks. The front cover is detachably mounted on the top of the front-end treatment chamber. Multiple sets of annular array electromagnetic rods at its bottom can specifically adsorb coarse iron slag. Guide plates on the electromagnetic rods guide the flow of the zinc liquid to improve capture efficiency. The inner and outer walls of the inverted convex mesh cylinder in the rear-end treatment chamber are equipped with annular array electromagnetic blocks. Combined with the rotation of the mesh cylinder via an annular rotating seat, a multi-dimensional magnetic field is formed to efficiently adsorb fine iron slag. The front cover on the top of the rear-end treatment chamber is quickly installed and removed via claws and bolts. A flushing pipe at the rear of the device can directionally flush the electromagnetic rods and mesh cylinder, and the rotation of the mesh cylinder efficiently removes iron slag. This device achieves graded treatment of coarse and fine iron slag, improving iron removal efficiency and quality.
