    (5) LOADING DEVICE OF MINE FURNACE
    one
    This invention relates to equipment for loading a shaft furnace.
    The closest to the invention to the technical essence and the achieved result is the charging device of the shaft furnace, containing a rotating hopper with a drive bottom, enclosed in a sealed casing, the upper part of which is provided with a bore hole and a sealing gate, the cylindrical reflector of the charge, while the bottom of the bunker is in contact with a driving cone ij.
    A disadvantage of the known device is the inability to influence or change the mass distribution of the material on the surface of the load.
    The purpose of the invention is to improve the distribution of the charge charged to the furnace.
    The goal is achieved by the fact that the device containing a rotating hopper with a power bottom, enclosed in a sealed casing, the upper part of which is made with a hole for entering the charge and with a sealing gate, a cylindrical reflector of the charge, while the bottom of the hopper is in contact with a drive cone suspended on a hollow rod, is equipped with a driving charge distributor, located under the cone and made in the form of a skirt, having the shape of a truncated cone, consisting of segments facing one another, each of which has 10, the shape of a sector with an annular surface, established by their narrow sides on a ring with pins and each connected to a rod connected to the lifting and changing drives on an IS clone of the segments.
    The device is equipped with a plate located at the lower end of the rod and made in the form of a star, each lui of which is equipped with a finger that interacts with each segment.

    25 parts of the distributor. 39 The distributor is located directly under the casing and contains two hydraulic cylinders, the piston of the first ци cylinder being connected on the one hand, to the hollow suspension rod of the cone and on the other hand to the third cylinder, the piston of which is connected to the distributor rod through the first cylinder and yluo barbell cone. The device is equipped with a cooling system containing the first ritany line with a refrigerant through a ring of nozzles located between the hollow bar and the distributor bar and serving each of the segments, and a second power line connected to the star-shaped plate using two channels coaxially intersecting the distributor bar. FIG. Figure 1 shows schematically the loading device in the loading position of a rotating bunker, as seen in the main section; in fig. 2 - the same, in the initial phase of the unloading operation of the material; in fig. 3 and 4 - unloading of the material at two extreme angular positions of the distributor. The loading device 1 (Fig. 1) is mounted on the shoulders 2 of the blast furnace 3 which make up part of the neck of the blast furnace 3. The loading hopper 5 is installed in a rotating housing 6 coupled with guiding devices 7 and 8 allowing the bunker to perform a vertical movement. The peripheral drive motor 9 is designed to communicate the rotation of the housing 6 and the hopper 5 through the water gear 10 and the bearing 11. The guide system 7 and 8 can be formed by two pairs of rollers with a concave rolling surface, each of which interacts with guides with a convex surface mounted on the hopper 5, which is supported by its weight and the conical bottom 12, the taper of which is upward and which serves as a protective and anti-wear shell. cone 13. Conic bottom 12 is rigidly connected to an axial tube 14 consisting of anti-wear elements surrounding a hollow rod .15, which serves to suspend a smaller cone 13 .. Pipe 1 (suspended on a hollow rod 15 by means of a bearing 16. Engine 9 communicates the rotational movement to the assembly formed by the rotating body 6, the guide system 7 and 8, the hopper 5, the conical bottom 12 and the tube H, while the sliding vertical movement of the hollow rod 15 allows the bunker 5 to slide in a vertical plane relative to the guide system 7 and 8. The hermetic casing 17 surrounding the rotating hopper 5 is hermetically mounted on the shoulder 2 and can be closed from the side of the blast furnace with a cone 13 when it is in the raised position adjacent to the saddle 18 fixed to the base of the casing 17. Hermetic casing 17 It communicates in the upper part with the receiving chute 19, from which it can be isolated with the help of the sealing gate 20. To the upper part of this receiving chute, transporting means (not shown), for example skips or conveyor belts, are provided. for feeding feed material. Under the cone 13, there is a conical distributor 21 suspended from the cone 13 by means of an intermediate circular part 22 rigidly connected to the cone 13. The distributor follows an upward and downward movement of the cone 13, and when this latter is lowered, the distributor 21 moves to the position indicated by dotted dashed line. The distributor 21 comprises a frusto-conical surface or skirt formed by a series of segments that overlap one another. 23 Each of these segments has a sector shape with an annular surface slightly curved so as to create this conical surface when they are subsequently raised, partially overlapping one another , around the axis of the furnace. Part 22 contains on its lower surface a ring with ribs 2 (the number of which corresponds to the number of segments. However, there is no need for all these edges to be located down to the cone 13). Each of the segments 23 is hinged to the corresponding edge with the help of pins and has on its lower concave surface a shoulder 25 formed by a welded or cast plate perpendicular to the segments 23; Each of the shoulders 25 has a slit 26, a finger 27 enters into an otopyvi, provided on the end 28 of the star of the shaped plate 29, The ends of which correspond to the number of segments. The plate is fixed on the lower end of the drive rod 30, coaxial with the hollow rod 15 and connected outside the hermetic casing 17 with the drive mechanism to raise or lower the plate 2E. The angular position of each of the segments 23 relative to the axis O i.e., their rolling around the pins, determines with the position of the plate 29. When the plate 29 is in the lowered position relative to the smaller cone 13, the segments diverge and the opening angle of the skirt becomes maximum. When the actuating rod 30 is raised relative to the smaller cone 13, the segments of п are released together in the directions of the axis O and the opening angle of the skirt is gradually reduced {to the position -fig. k) Between the two extreme positions (figs. 1 and 4) the skirt passes through a cylindrical position, i.e. in the extreme positions (fig. 1 and), the skirt tapers are opposite. The angle of rotation / (0ig, 1) of each of the segments 23 between the two extreme positions is 60. When the plate 29 slides, each of the fingers 2 slides in the slot 26 of the matching shoulder 25 to provide a transition between the vertical movement of the palde 27 and the rotary movement of the slots 26 around the pins . When the angle is 60 °, it is preferable that the axis of the target 2b is in both extreme positions an angle of 30 relative to the horizontal plane passing through the pins. The number of segments must be a divisor of the number 360 and equal to at least 16 (preferably 2). It is not necessary for the segments to be too large to maintain thermal expansion in acceptable. the limits. From the geometry of the SRI, the width of the segments on the outer side opposite the pins m should not be too large in order to ensure that the skirt is sufficiently closed. Segments are made of special heat-resistant steel with good wear-resistant properties. A circular reflector 31 is provided around the distributor. Its lower edge converges in the direction of the axis so as to direct the material coming out of the hopper 5 to the skirt of the distributor 21. A drive device 32 for driving the cone 13 and controlling the opening angle of the skirt is installed directly above the case 17. The floor of the rod 15 of the cone 13 passes through the case 17, the oil seal and is connected to the removable yoke 33 with the rod 3t of the hydraulic power cylinder 35. The drive rod 30 the distributor 21 passes through the entire semi-rod 15 and the power cylinder 33 and is driven by a second power cylinder 36 mounted above the cylinder 35 and rigidly connected to the piston of the cylinder 35 so that the cylinder Zb follows vertically slide the movement of the hollow rod 15. The pipes 37 and 38 for supplying coolant are designed to cool certain parts of the distributor 21. The pipe 37 for feeding a certain number of tubes (not shown) located on the ring between the hollow rod 15 and the driving rod 30, for supplying cooling fluids in pipelines passing through the ribs 2, pins, segments, and possibly through the shoulders 25. a second coolant circulation can be provided through the inside of the drive rod 30, from the pipeline 38 to 28 ends the star plate 29. The cooling plate 29 and various segments increases their mechanical strength and thus reduces the risk of deformations. The supply and distribution of the material during the loading cycle corresponding to the filling and emptying of the hopper 5 is carried out as follows. When filling the hopper 5, the lower cone must be tightly abutted against its seat 18 in order for the furnace to be sealed off from the outside environment. After opening the gate 20, feed is fed through the receiving chute 19. A continuous or periodical rotational movement is reported to the bunker according to whether the material is fed into the chute 19 by means of a conveyor belt or skips, to ensure uniform filling of the hopper 5 by means of the motor 9. After filling 79 of the hopper 5, the gate 20 is closed and pressure is equalized, the pressure inside the housing is adjusted using known means to the pressure inside the furnace. The next stage consists in actuating the power cylinder 35 to lower the hollow rod 15 supporting the cone 13. Lowering the cone 13 results in the passage of the pipe Il, i.e. the entire loading hopper 5 to the guide system 7 and 8. Starting from a certain point (Fig. 2), the lowering of the bunker 5 is stopped by a shock-absorbing ring located in the inside of the housing 17. During the downward movement of the bunker 5, the engine stops. In the position (Fig. 2), when the bunker is blocked by shock absorbers 39 and AO, the bottom of the bunker, having the shape of a funnel, closes the saddle 18, namely its sealing surface. The downward movement continues of the assembly formed by two coaxial rods 15 and 30, a cylinder 36, a cone 13, a conical bottom 12 and a distributor L, the bottom of the hopper 3, thus gradually opening up to the maximum opening (FIG. 3), and the load containing c in the bunker 5, is released and follows a falling trajectory defined by a conical bottom 12, a reflecting body 31 and a skirt. At maximum opening of the skirt (Fig. 3), the material is directed to the loading surface along the periphery. In order to ensure the filling of material into the central section around the axis O, it is sufficient to actuate the power cylinder 36 in order to lift plate 29 and lower the skirt (Fig. 4). In this position, the skirt is almost outside the trajectory of the fall defined by the reflector 31. Of course, it is possible to distribute the loaded material in the intermediate section (between the sections shown in Fig. 3 and k), choose the appropriate opening angle for this skirts. The saddle 18 is bolted to the upper surface of the lower shoulder of the casing 17, the inner diameter of which is greater than the maximum outer diameter of the cone 13 and the distributor 21. This makes it possible to dismantle the assembly consisting of the cone 13 and the distributor 21 by removing the cut of the shoulder after dismantling the seat 18 and the bottom kl of the hopper 5 and brings the distributor 21 into position (FIG.). The fact that the drive device is mounted directly on the casing 17 makes it possible to obtain an extremely low construction and makes the conventional cone tower unnecessary. The second factor contributing to the low construction is that the proposed boot device has only one cone and that the distributor 21 can be led to this cone 13 if there is no longer a load between this cone 13 and the distributor 21. The application of the invention ensures quality distribution of charge materials loaded into a shaft furnace, for example a blast furnace. The boot device is easy to manufacture, has small dimensions and is reliable in operation. Claim 1.
