The invention relates to the production of blast furnaces, namely, the distributor of the mixture of charging devices for blast furnaces.

The aim of the invention is to increase reliability and increase service life.

FIG. 1 shows the charge distributor, general view; FIG. 2, view A in FIG. one.

The charge distributor contains sta- 1 {ionic charge chutes 1, fixed on the dome 2 of the furnace, under which rotor 3 is suspended on rod 3, Rod 3 is guided into hole 5, made in dome 2 along the axis of the furnace. The outside of the rod 3 is fitted with a bellows 6 with a sealed collar 7, with which the upper end of the rod 3 and the inner ring 8 of the universal joint are rigidly connected and pivotally mounted on the pins 9 in the outer ring 10. The outer ring 10 and pins 11 are perpendicular to the pivots 9 of the inner ring 8, is installed with the possibility of rotation on the supports 12, rigidly fixed on the dome 2 of the furnace. The rod 3 is rigidly connected to the funnel 4 by means of the traverse 13. The trunnions 9 of the inner ring 8 and the trunnions 11 of the outer ring 10 are connected with the turning drives (not shown conventionally).

funnel 4 describes a cone around the vertical axis of the blast furnace. Charge materials coming along the chute 1 are moved along a spiral trajectory inside the funnel 4 and dumped onto the ladle, forming an annular ridge.

whose radius of pivot turning is 9

is determined by the angle and 11. When the amplitude of rotation of the trunnions changes, the radius of the ring ridge of the charge is changed.

The device allows loading in the .strip scan mode, and local loading of any zones of the furnace's top, including the spiral and working, ridge-shaped forms.

For the manufacture of bellows 6, it is possible to use a set of compensators. With a compensator height of 178 mm and a deflection angle of 3 °, a set of seven compensators will provide a total deviation of 21.

The invention will allow the cardan suspension and all hinges and friction pairs to be blown out of the furnace, as well as to exclude all glands and movable seals. These features will ensure a 2-fold increase in reliability, a 3-fold reduction in stopping time of the furnace and an increase in the maintainability of the device.
