Description

Technical Field

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

[0002] Hot-dip galvanizing is one of the most effective means to delay environmental corrosion of steel materials. It is to immerse the steel products after cleaning and activation in molten zinc liquid, and through the reaction and diffusion between iron and zinc, a zinc alloy coating with good adhesion is plated on the surface of the steel products. Hot-dip galvanizing is a surface treatment method in which metal products are immersed in molten zinc to form a dense zinc layer on the surface of the products. This process technology is also called hot-dip galvanizing or hot-dip galvanizing. The main purpose of hot-dip galvanizing is corrosion protection. Through the reaction and diffusion between iron and zinc, a zinc alloy coating with good adhesion is plated on the surface of steel products, thereby achieving the purpose of corrosion protection. In order to remove the slag generated during the galvanizing process, a slag removal device is required in the hot-dip galvanizing production process. During the hot-dip galvanizing process, the iron parts are wetting the plating agent, immersed in the zinc bath, and react with the molten zinc to form an alloyed film. In this process, a certain amount of slag will be generated inside the galvanizing pool. If these slags are not removed in time, they will affect the actual galvanizing operation.

[0003] China has authorized a utility model patent to disclose a hot-dip galvanizing slag scooping device (publication number: CN219342250U). The utility model is to slide a telescopic structure on a base frame, drive the telescopic structure to move with a driving structure, and then set the slag scooping structure at the telescopic end of the telescopic structure, so that the slag scooping structure can slide on the base frame with the telescopic structure, and then scoop the zinc slag in the zinc pot. At the same time, the telescopic structure is arranged in a vertical direction, and the telescopic structure drives the slag scooping structure to move up and down. When the slag scooping structure moves down to enter the zinc pot, the slag scooping is carried out. When the slag scooping is completed, the telescopic structure drives the slag scooping structure to move upward to leave the zinc pot, so as to pour out the zinc slag in the slag scooping structure. The operation is convenient, the work efficiency is improved, and the safety is high and the practicality is good. In the process of implementing the scheme, the inventor found that the scheme had the following problems during implementation: a slag scooping structure was installed at the bottom end of the telescopic structure of the utility model. When the slag scooping structure was in use, the installation direction of the slag scooping piece of the slag scooping structure was fixed. When in use, the slag scooping piece of the slag scooping structure could only perform simple salvage of the zinc slag inside the zinc pot. It was not convenient to use and required repeated salvage operations many times. The overall salvage effect was not good. The inclined end face opening of the slag scooping piece was large, which made it easy for the zinc slag inside the slag scooping piece to fall off, thereby affecting the use of the slag scooping device.
