STOCK DISTRIBUTOR OF BLAST FURNACE CHARGING DEVICE Russian patent published in 1995 - IPC

FIELD: metallurgy. SUBSTANCE: the stock distributor of the blast furnace charging device has a receiving hopper, moveably conjugate to a telescopic hopper, and small bell with a sealing cup installed an the gas seal. To enhance the blast furnace capacity due to the increase of uniformity of stock distribution in circumference on the furnace top, the receiving hopper is made bell-shaped and furnished with an additional telescopic hopper that is located inside and freely conjugate to it with formation of an annular accumulating vessel; the telescopic hopper is secured on the rod of the small bell for rotation relative to the rod. In turn, the receiving hopper has a vertical diaphragm dividing the annular accumulating vessel into two equal (parts) chambers, and the additional telescopic hopper has a mouth in the form of a truncated cone, whose point of intersection of generators extends on the vertex of the small bell, and the diameter of the discharge opening is larger than the diameter of the stock largest particle by two times. EFFECT: enhanced furnace capacity. 2 cl, 2 dwg
