Supplying bedding ore from the ore hopper 3, leveling the level of the ore using the leveling device 4, igniting the ore using the ignition device 5, and sintering the ore in this order. The sintered ore is discharged from the terminal end of the outward path toward a cooler (not shown). A wind box 6 is provided at the bottom of the ignition and sintering zone during the forward pass, so that ventilation is carried out in the raw ore layer 7 in the pallet group 1 during ignition and sintering. So this Wind Box 6
An air seal device is provided at an ore feed side end 6A, an ore discharge side end 6B, and an intermediate section 6C that separates the ignition furnace low negative pressure section and other high negative pressure sections.

より行なわれている。 FIG. 2 shows an example of a conventional air seal device, in which a seal plate 9 is attached to a pallet group 1.
is swingably supported on a fixed base 11 by a shaft 10 perpendicular to the traveling direction A at one end side, and a predetermined sealing pressure is applied to the bottom surface of the pallet group 1 by a compression spring 12 at the other end side. It is pressed together. On the other hand, sealing between the seal plate 9 and the wind box 6 is achieved by fixing a flexible connecting plate 14 with bolts 15 between the underframe 13 on the wind box 6 and the seal plate 9. ing.

る。 A problem with such an air seal device is that the seal plate 9 is biased only on one side by the spring 12 and brought into pressure contact with the pallet group 1, which causes uneven wear on the seal plate 9. In addition, the contact state of the bottom surface of pallet group 1 with seal plate 1 differs depending on the thermal deformation and manufacturing precision, so the bottom surface of pallet group 1 may come into contact with seal plate 1 with an impact, causing excessive force. It's easy to get caught. In addition, asbestos is usually used for the connecting plate 14, but it is easily deformed due to the large pressure difference between the inside and outside, and if there is a falling ore at the corner, it will be easily damaged.
Moreover, once a hole is formed, the damage progresses rapidly due to the passing dust-containing air, and it takes time to replace it.

きる。 Therefore, the present invention provides an air seal device for the feed/discharge section and intermediate section of a sintering machine that solves these problems, and its features are as follows:
A rotating device having a pair of rotating bodies and an endless body wound between the two rotating bodies is installed between the endless pallet group that rotates in one direction and the wind box connection seal plate. The rotating body on the rear side in the direction of movement of the pallet group is placed closer to the pallet than the front rotating body, and the endless body is arranged so as to be rotatable in the same direction as the pallet main beam. A plurality of guide plates are provided that protrude with pitches that match the spacing between the pallet main beams and engage with the front side in the traveling direction of the pallet main beams whose tips face each other. An elastic seal plate is provided protrudingly, and a flexible seal member is provided to join the seal plates to each other, and when the elastic seal plates are moved forward, their tips abut against the bottom surfaces of the opposing main beams of the pallet, and when returning The main reason is that the tip is configured so that it comes into contact with the wind box connection seal plate when the wind box is moved. According to this configuration, since the elastic seal plate rotates integrally with the opposing main pallet beam while being in contact with the pallet main beam, the sealing performance between the elastic seal plate and the pallet main beam is extremely good. Furthermore, the elastic seal plate and the pallet main beam do not wear out each other, so that the service life can be maintained for a long time.
