Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary components of a bottom blowing furnace, in particular to an automatic cleaning device for a feeding port of a bottom blowing furnace. Background Art

[0002] Bottom blowing furnace is an indispensable process step in the existing metallurgical process. In the actual production process, the high-temperature melt in the bottom blowing furnace boils and splashes to the feeding port. The splashes and the concentrate material adhere to the lower part of the feeding port, which can easily cause the incoming materials to be unable to enter the bottom blowing furnace smoothly and cause the feeding port to be blocked. In order to prevent the feeding port from being blocked, a 3-meter-long drill rod is required to be manually operated to clean and dredge the feeding port.

[0003] The flue gas density at the bottom blowing furnace charging port is high and the temperature is high. When using a drill rod to clean it, since people are cleaning the charging port, they are directly affected by the high temperature and flue gas. It is impossible to clean it for a long time manually. Once slag spraying occurs, safety accidents such as burns are very likely to occur. Utility Model Content
