Description

Technical Field

[0001] The utility model patent belongs to the technical field of zinc smelting equipment, and specifically relates to a feeding device for an electric furnace in a zinc plant. Background Art

[0002] When zinc plants produce zinc ingots, they usually mix raw materials such as zinc roasted sand, quicklime, and quartz sand to form a mixture, then put it into an electric furnace for smelting, and finally make zinc ingots. In this process, although the existing feeding device used in zinc plants can complete the feeding operation, it still has the following disadvantages in actual use:

[0003] 1. Because the electric furnace used for smelting is very large, multiple feeding ports are usually designed on the electric furnace to ensure that the ore can be put into the electric furnace as evenly as possible. The existing feeding method is to load the mixed ore into a cart and then manually feed it to each feeding port. This method is time-consuming and labor-intensive, with too much labor and low feeding efficiency. In addition, there are certain safety hazards caused by multiple contacts with high-temperature electric furnaces.

[0004] 2. At the same time, the process of feeding materials in this way will create a lot of dust, which will pollute the air and seriously endanger the health of on-site workers.

[0005] In order to solve the above problems, this paper proposes a feeding device for an electric furnace in a zinc plant. Utility Model Content
