    This invention relates to ferrous metallurgy, in particular to designs of charging devices for shaft furnaces.
    The purpose of the invention is to reduce the dimensions of the furnace and to increase the uniform distribution of the material along the radius of the furnace.
     FIG. 1 shows a device with two rotating bunkers, a general view with a partial vertical section in FIG. 2 - assembly of two chambers on the furnace head, plan} in FIG. 3-5 - valve housing with different phases of the connection of the housing with the hopper, axial section,
    In the upper part of the shaft furnace 1, a chute 2 of distribution of the feed material is mounted in its head, which is driven by a drive 3 of a known type to ensure that chute 2 rotates around the vertical axis O, and also to specify its angular position relative to this axis. On the actuator 3 is located 4 valve housing.
    On the furnace 1 there are two bins 5 and 6 which can be moved by turning around a vertical axis X parallel to the central axis
    0pech and located between the position of loading, which shows
    the bunker 6, for which the bunker 5 and 6 are placed on the frame 7 in the form of a double plug (Fig. 2), resting on the rotary plate 8, which is driven by the motor 9 and is supported by the stand 10 located on the furnace head 1. Two hoppers 5 and 6 is attached to the frame 7 through three groups of weighed spring devices 11, which allows, in a known manner, to continuously monitor the contents of each of the bins 5 and 6 for automatically controlling the operation of the dampers.
    The feed material is fed using a belt conveyor 12 to the hopper 13, which is above the bunker in the loading position (in this case, above the hopper 5). The hopper 13 is suspended from the cross beam 14, mounted horizontally on the axially rotatable rod 15, which is driven in rotation by the engine 16. Rotation of the hopper 13 during loading significantly reduces the segregation of particles discharged by the loading bar.
    tape 12 into the bunker. The vertical plate 17 fixed opposite the conveyor belt 12 and the plate 18. fixed to the lower end of the rod 15 and moved 1 ertically under the influence of the jack are additional measures for reducing the segregation in the hopper 13. The vertical position of the plate 18 is adjusted depending on the level of material in the hopper 13, this level being measured by known level sensors. It is actuated so that the feed material in the hopper 13 has a more or less constant volume.
    To reduce segregation inside the bins 5 and 6, there are one or more plates 19, which are fixed inside the bins 5 and 6 on their axis to ensure the distribution of the feed material falling from the bunker 13 as well as in the chamber 5.
    The pressure equalization pipe 20 serves to pressurize the hopper during unloading in the position of the hopper 6 before opening the valves for discharging to the distribution chute 2 and for aerating the same bunker 6 after closing the damper valves and also before inverting the positions of the two hoppers 5 and 6. blowing the bins each of them is equipped with a bypass pipe 21 connecting the lower part of the bins directly to their upper part. Pipeline 20 must be equipped with cardan compensators to resume disconnection of the valve body 4, as well as the movement of the furnace 1.
    . The frame is represented by three racks 22-24, which carries the top of the furnace 1 and which in turn support the horizontal plate 25. The rotatable plate 8 is placed with help. rolling bearings (not shown) on plate 25. The evacuation pipelines for hot gases from furnace 1 are shown at position 26. The frame 7 rotates around the vertical axis X and the inversion of the positions of the hoppers is carried out without interference from the pipelines 26, the evacuation of hot gases from furnace 1 which inclined with respect to the vertical plane.
    For operation of the device means are provided to ensure a tight connection between each of the bins 5 and 6 and the body of the 4 flaps (Fig. 3-5).
    In order to provide quick and easy mounting between each of the bins 5 and 6 and the valve body 4, the latter is movable in the vertical axial direction and connected via a compensator 27 to the casing 28 of the drive mechanism 3 of the chute 2 (Fig. 1). The compensator 27 is associated with several (preferably three) positioning cylinders 29 (Fig. 5), each of which has a sliding piston 30 subject to pressure from the spring 31. Under the influence of the spring 31 of the weight of the valve body 4, the body 4 normally rests on cylinders 29, with compensator 27 being in a compressed state. In addition, the spring 31 is necessary to compensate for the reaction of the furnace 1 when none of the bunkers b and 6 rest on the body 4.
    The valve body 4 also has an upper annular sealing surface 32 around which several (preferably three) hydraulic cylinders 33 are fixed. Each of them has a piston with a vertical rod with an expanded cylindrical head 34. When the upper part of the valve body 4 is released, two valves 35 and 36 should be closed (Fig. 3, the device in the phase of rotation of the two bins 5 and 6).
    Each of the bins 5 and 6 has at its base in places corresponding to the hydraulic cylinders 33, side panels 37, provided with grooves 38, the shape of which corresponds to the shape of the head 34 of the cylinder 33. When one of the bunkers, for example the bunker 6, is rotated in the discharge position ( Fig. 4), each of the slots 38 is driven to one of the respective heads 34 of the hydraulic cylinders 33.
    The lower supply pipe of each of the hoppers 5 and 6 is provided with an annular sealing surface 39 corresponding to the upper sealing surface 32 of the valve body 4, and these two sealing surfaces 32 and 39 have a corresponding shape (for example, convex and concave). Gas tube 40 comes out in the center of the upper surface 39
    five
    sealing and its task is to provide cleaning of sealing surfaces 39 and to contribute to ensuring tightness by injecting gas under pressure in the opposite direction.
    The connection between the hopper 30 and the valve body 4, (FIG. 3), is realized by injecting hydraulic fluid into the cylinders 33 from the side of the piston rod until the sealing surfaces 32 and 39 come into mutual contact. The lifting of the shutter core 4 is accomplished by ensuring that the pistons slide in the positioning cylinders 29 by compressing the springs 31 and stretching the compensator 27.
    Q The separation of the hopper 6 and the valve body 4 is done in the same way, but in reverse order.
    Since each of the bins 5 and 6 is disconnected from the body 4 of the plate during rotation about the X axis, they must be provided with a lower retainer valve 41 to hold the feed material. In addition, each of the bunkers 5 and 6 has classic loading chambers according to a well-known technology - the top seal of the flap 42.
    The application of the invention will improve the uniformity of distribution of materials along the radius of the furnace and reduce its dimensions.
