BLAST FURNACE FEEDING EQUIPMENT Russian patent published in 2015 - IPC C21B7/20 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, namely, to the feeding equipment of the blast furnace. The device contains the stock distributor fixed on the flange of the furnace throat and designed with the central stock funnel, driving distribution tray, storage hopper with bottom stock gate and a gas valve mounted above the storage hopper the intermediate hoppers with top stock gates and the gas valves, bellows compensator fixed between the stock distributor and the bottom gas valve, technological damper plate placed between the distributor flanges and the bellows compensator. The driving distribution tray is designed as a tapering downwards pipe, and is suspended in the distributor housing on semi-shafts vertically on its axis using the quick connector with a possibility of deviation of the tray from the vertical axis to the angle no less than 50°, in both sides. Axial opening of the distributor housing and distribution tray are made with geometrical parameters ensuring free passing of the distribution tray through the axial opening during dismounting. The walls of hoppers and adjacent walls of bottom and top stock gates are designed as the truncated cones, the central corner of which is equal to 62-78°.

EFFECT: invention provides minimising of the device height.
