SHAFT FURNACE CHARGING INSTALLATION AND METHOD OF SHAFT FURNACE CHARGING Russian patent published in 2016 - IPC F27B1/20 C21B7/20 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and can be used during shaft furnace charging. Charging installation comprises first and second collecting bins arranged parallel to each other, wherein each of first and second collecting bins has inlet hole to receive material and outlet hole for material charging into shaft furnace. Receiving bin is arranged to turn about horizontal axis of rotation and is designed for receiving and distributing material into one of first and second bins, wherein receiving bin is made with possibility of rotation at least between two transfer positions, wherein in the first transfer position receiving bin outlet is arranged coaxially with first collecting bin inlet opening, and in second transfer position is coaxially with second collecting bin inlet opening. Charging installation also contains material gate, related to receiving bin outlet opening, and drive mechanism related to material gate, for receiving bin outlet hole opening and closing, wherein drive mechanism is made with possibility to close outlet opening when receiving bin is in rest position and outlet opening when receiving bin is in any of first or second transfer positions. Drive mechanism is made with possibility to actuate material gate due to receiving bin turning movement.

EFFECT: invention allows creating special material gate structure able to prevent charge material residue fall on closed sealing valve or against falling between two collecting bins.
