Description

Technical Field

[0001] The invention belongs to the technical field of antimony smelting, and in particular relates to a feeding device and method for an antimony smelting blast furnace. Background Art

[0002] At present, all antimony smelting blast furnaces use top feeding. During the feeding process, a large amount of valuable materials will overflow with the flue gas through the feeding port. Although equipped with a dust collection device, a large amount of flue gas and dust will still escape, causing environmental pollution and the loss of valuable materials. In addition, the raw materials need to pass through the exhaust port before they can fall into the furnace for smelting. This feeding method causes a large amount of fine dust particles to pass through the exhaust port. The dust enters the fire cabinet with the exhaust. Because the volatilization temperature of antimony cannot be reached, a large amount of powder becomes antimony sulfide. It is necessary to manually enter the fire cabinet for cleaning and put the mixed materials such as antimony sulfide into the furnace for smelting again. This process has a large amount of reverse materials repeatedly entering the furnace for smelting, resulting in huge waste and occupational hazards. Summary of the invention
