Equally around the circumference of flange 3, horse The invention relates to blast furnace production and can be used in the charging devices of blast furnaces.

The aim of the invention is to simplify the design and increase reliability in operation.

FIG. 1 shows the charge distributor, vertical section in FIG. 2, section A-A in FIG. 1j in Figure 3, section B-B in FIG. 1,

The device contains an upper cylindrical funnel 1, a conical funnel 2 with a flange 3 and a contact surface 4, a drive cylindrical body 5 communicated with a rotation drive (conventionally not shown), a gas sealing cone 6 with a contact surface 7 fixed on a hollow rod 8 mounted on bearings 9 on traverse 10 communicated with a vertical movement drive (not shown). On the gas-sealing cone 6 on the opposite side of the rod 8 and coaxially with it, the rod 11 is rigidly fixed, on which by means of bearings 12 a truncated cone 13 is installed with the contact surface 14 with the possibility of contact with the contact surface 15 of the stationary ring

chesky funnel. 2, the protrusions 23J are firmly fixed in contact with the recesses 24 made in the drive case 5. The flange 3 is connected to the case 5 by bolts 25; gas sealing cone with evenly spaced circumferentially and contact cuts and protrusions, and the flange of the conical funnel and the cylindrical body are made with evenly spaced circumferentially protrusions recesses in contact with each other. 3 silt

16, rigidly fixed between the upper and lower portions 17 and 18 of the gas valve housing with bolts 19; Sealing the cylindrical drive body 5 and the stationary ring 16 relative to the upper and lower parts; 17 and 18 gas valve housing seals are made with the glands 20, 21 and 22. Uniformly around the circumference of the flange 3 of the conical funnel 2, the protrusions 23 are rigidly fixed, which are in contact with the recesses 24 made in the drive housing 5. The flange 3 is connected to the housing 5 with the help of evenly spaced bolts 25 around the circumference. s portion is formed with notches 26 in contact with conical protrusions 27 June.

The device works as follows obiJaaoM,

The charge materials are loaded into the conical funnel 2 onto a cone, after which the drive body 5 is rotated to the required angle. Then the cone 6 is lowered, and the loose materials are dropped into the inter-conical space, limited by the gas gate, after which the cone 6 is closed. When supplying gas to the cone

the space for equalizing the pressure above and below the large cone; the gas sealing functions fulfill the contact surfaces 4 and 7 of the conical funnel 2 and the cone 6; The contact surfaces 14 and 15 of the truncated cone 13 and the rings 16 are outside the path of movement of the charge and are not subject to wear. After wear of the contact surfaces 4 and 7, the transition to the operation of the contact surfaces 14 and 15 is carried out. For this, taper 6 is lowered until its projections 27 come out. from the contact with the notches 26 of the conical funnel 2. Then the drive funnel 5 is turned in such a way that the projections 27 are between the notches 26, the funnels 1, 2 and the housing 5 are separated, for which the bolt joints 25 are removed. and together with it, the conical funnel 2, until its protrusions 23 come out of contact with the recesses 24 of the drive housing 5. Then they rotate the drive housing 5 by an angle at which the projections 23 are located between the recesses 2A and are not in contact with them. Then the cone 6 is lowered until the protrusions 23 of the funnel 2 come into contact with the drive body, after which the funnels 1.2 and the body 5 are bolted together 25, in which case

5 pre-made additional holes. As a result, the funnel 2 is raised relative to the body 5 to the height of the protrusions 23. Then, the drive body 5 is turned with the cone lowered

6th so that the projections 27 again entered the notches 26. When raising the cone 6

contact surfaces are brought into contact with a friend.

14 and 15 of the truncated cone 13 and the ring 16, while a gap remains between the contact surfaces 4 and 7.

Due to the reliability and

simplify the design of the downtime of the blast furnace, the reduction of the TC by 0.25%.
