As shown in FIGS. 5 and 7, among the plurality of hoppers 10 constituting the sinter cooling device 1, there is a gap (circumferential gap) between the lower end portions 10b of the pair of hoppers 10 adjacent to each other in the circumferential direction. ) 50 is formed. In the exemplary embodiment shown in FIGS. 5 and 7, the circumferential distance between the circumferential side wall portions 8 of the pair of hoppers 10 adjacent to each other in the circumferential direction increases toward the downward direction.

In the above-described embodiment, a plurality of hoppers 10 for depositing the sinter 5 are arranged in a ring shape, and a circumferential gap 50 is formed between the lower ends of a pair of hoppers 10 adjacent to each other in the circumferential direction. By doing so, as shown by the arrows in FIGS. 5 and 7, air from the circumferential gap 50 can be taken into each hopper 10. That is, in addition to taking in air into the hopper from the radial direction as in the conventional sinter cooling device, it is possible to take in air into the hopper 10 from the circumferential direction as well.

In the exemplary embodiment shown in FIGS. 5 to 8, the inner peripheral side louver 64 is incorporated in the inner peripheral wall portion 3 of the hopper 10, and the inner peripheral side louver 64 is incorporated from the inner peripheral side region of the hopper 10. Air can be taken into the inside of the hopper 10 through the louver. Further, in the exemplary embodiment shown in FIGS. 5 to 8, the outer peripheral side louver 62 is incorporated in the outer peripheral wall portion 4 of the hopper 10, and the outer peripheral side louver 62 is incorporated from the outer peripheral side region of the hopper 10 via the outer peripheral side louver 62. Air can be taken into the inside of the hopper 10.

In some embodiments, for example, as shown in FIGS. 4, 5 and 7, the plurality of hoppers 10 constituting the annular row are such that the upper end portions 10a of the pair of hoppers 10 adjacent to each other in the circumferential direction are in contact with each other. Placed in.

In this way, since the plurality of hoppers 10 constituting the annular row are arranged so that the upper end portions 10a of the pair of hoppers 10 adjacent to each other in the circumferential direction are in contact with each other, for example, they are fired in the gap between the pair of hoppers 10 adjacent to each other. It is possible to prevent the sinter 5 from falling, and the sinter 5 supplied from above can be appropriately introduced into the internal space 6 of the hopper 10.

In some embodiments, for example, as shown in FIG. 4, the upper end portions 10a of a pair of hoppers 10 adjacent to each other in the circumferential direction are connected to each other by a connecting tool 80. In this way, by connecting the upper end portions 10a of the pair of hoppers 10 adjacent to each other in the circumferential direction by the connecting tool 80, the upper end portions 10a of these hoppers 10 can be more reliably brought into contact with each other.

In some embodiments, for example, as shown in FIGS. 1-9, the sinter cooling device 1 is provided on the inner peripheral side of the annular row of the plurality of hoppers 10 to support the plurality of hoppers 10. A support member 40 is provided.

According to the above-described embodiment, since the support member 40 for supporting the plurality of hoppers 10 is provided on the inner peripheral side of the annular row of the plurality of hoppers 10, the radial side is directed toward the center of the rotary table 30. The scraper 28 provided so as to extend does not interfere with the support member 40. Therefore, with the hopper 10 supported by the support member 40, the sinter 5 deposited on the rotary table 30 can be appropriately discharged by the scraper 28.

In the exemplary embodiment shown in FIGS. 1-9, the support member 40 is provided outside each hopper 10.

In the sinter cooling device using the conventional annular hopper, in order to support the outer peripheral wall of the annular hopper, a support member extending inside the annular hopper is usually provided. In this case, since the support member is exposed to a high temperature, it may be necessary to cool the support member. On the other hand, in the above-described embodiment, since the support member 40 is provided outside the hopper 10, it is less necessary to cool the support member than when the support member is provided inside the hopper 10. Therefore, the structure and device for cooling the support member 40 can be omitted or simplified to reduce the cost.

In this way, each hopper 10 can be appropriately supported by a simple configuration using an arm 42 fixed to a portion of the rotary table 30 on the inner peripheral side of the annular row of the plurality of hoppers 10. Further, since the support member 40 (arm 42) is fixed to the portion of the rotary table 30 on the inner peripheral side of the annular row, the region on the inner peripheral side of the support member 40 can be effectively used for purposes other than support. ..

In some embodiments, the support member 40 includes a plurality of radial beams 46 that are rotatably supported by the stanchions 38, for example as shown in FIGS. 2 and 7-8. Each radial beam 46 extends radially from a central bearing 33B provided on the outer peripheral side of the column, and is rotatably supported by the column 38 via the central bearing 33B.

In the exemplary embodiment shown in FIGS. 7 and 8, the plurality of hoppers 10 have a protrusion 78 provided so as to project in the circumferential direction from the circumferential side wall portion 8 of the hopper 10. It may be supported by the radial beam 46 via the 78. As shown in FIGS. 7 and 8, a support beam 48 for reinforcing the support of the radiation beam 46 may be provided between the radiation beam 46 and the rotary table 30.

In some embodiments, for example, as shown in FIGS. 1 to 4, 6 and 8, the sinter cooling device 1 is located on the rotary table 30 at a position separated from the plurality of hoppers 10 on the inner peripheral side. It is provided with a fall prevention plate 36 for preventing the sinter 5 from falling from the rotary table 30.

In the sinter cooling device 1 in which a plurality of hoppers 10 are arranged in an annular shape, unlike the conventional annular hopper, the lower end of the inner peripheral wall portion 3 of the hopper 10 and the rotary table 30 are separated in the vertical direction. Therefore, the sinter 5 discharged from the lower opening 14 of the hopper 10 may be deposited on the rotary table 30 at a position radially inside the lower end of the inner peripheral wall portion 3. Further, the sinter 5 deposited on the rotary table 30 may be extruded inward in the radial direction by the scraper 28.

In this regard, in the above-described embodiment, since the fall prevention plate 36 is provided at a position away from the plurality of hoppers 10 on the inner peripheral side, the fall prevention plate 36 from the rotary table 30 is suppressed from falling to the inner peripheral side. be able to. Further, since the fall prevention plate 36 is provided at a position away from the plurality of hoppers 10 on the inner peripheral side, a space is formed between the hopper 10 and the fall prevention plate 36, so that the area on the inner peripheral side of the hopper 10 is formed. Therefore, air can be taken in properly.

As already described, the plurality of hoppers 10 may have a shape having a circular cross section, for example, as shown in FIG. In this case, a top plate 82 may be provided to connect the upper end portions 10a of the plurality of hoppers 10. This prevents the sinter 5 supplied from above from falling between the hopper 10 and the hopper, and the sinter 5 can be appropriately received in the internal space 6 of the hopper 10. As shown in FIG. 9, the upper surface plate 82 may be supported by a support beam 84 provided between the upper surface plate 82 and the rotary table 30.
