  • An exhaust duct 52 is connected to a predetermined place of the stationary hood 51.
  • a partition plate 47 is provided for every connection air duct 26 (every pan carriage 7) in the movable air path 25 of the movable circular duct 21, as shown in Fag. 14.
  • a labyrinth seal 43c is provided at the upper end of the partition plate 47 closely to the dead plate 42. This causes the movable air path 25 to be partitioned for every section having the connection air duct 26 in the circumferential direction (in a direction of rotation).
  • the water sealing device 28 has no such partition plate.
  • a waste heat recovery zone D may be provided in a part of the cooling zone C in some cases, as shown in Fig. 15 . In the waste heat recovery zone D, heat is recovered from the hot air which is used for cooling sintered ore, and then, the air is sent to the stationary circular duct 31 again as the cooling air.
  • the sintered ore cooling facility having the above-mentioned structure has the following problems.
  • the pressure of the movable air path 25 and the cool-air box 12 is the atmospheric pressure in the feed and discharge zone B.
  • the pressure of the movable air path 25 in the cooling zone C is 300 to 500 mmAq (referred to as "differential pressure in cooling”, hereinafter).
  • the latter pressure is kept also in the upper space of the water seal chamber 24i by means of the dead plate 42 and the labyrinth sealing plates 43a, 43b and 43c due to the structure.
  • the length of the dead plate 42 is 10 m or more, and therefore, it is difficult in view of technology of manufacture to completely seal the dead plate 42 having such long length.
  • the sealing water splashed and accumulated in the movable air path 25 will further splash about the pan carriage 7 to adhere to a wall surface in the feed and discharge zone B or in the pan carriage 7. And, the dust of the sintered ore adheres to the adhered drops of water and solidifies and grow to become the wet dust, which causes troubles such as corrosion or a clogging of the pan carriage 7, so that normal operation is disturbed. Furthermore, wave or splash of the sealing water deteriorates water-sealing performance. This lowers cooling efficiency.
  • levels of an upper end of the partition plate 47 and upper ends of the labyrinth sealing plates 43a, 43b and 43c should be adjusted in all over the zone to be controlled so that gaps between the dead plate 42 and the partition plate 47 become almost closed. It is difficult, however, to control the large number of labyrinth sealing plates 43a, 43b and 43c provided in the extremely long length of movable circular duct 21. The operations and aging of the facility further widen the gap and deteriorate the sealing performance, but it is impossible to rectify during the operation of the facility.
  • Patent Reference 3 has proposed that the upper spaces of the water seal chambers 24i and 24i on a movable air path 25 side are supplemented with compressed air (auxiliary air) in the feed and discharge zone B, as shown in Fig. 16 , for the purpose of prevention of troubles caused by splashing of the sealing water.

  • the auxiliary air supplied from the branch ducts 61a and 61b is supplied to the upper spaces of the inner water seal chambers 24i and 24i from a space between expansion joints 41, which are provided at intervals, through both side parts of the dead plate 42.
  • This allows the auxiliary air supplemented from the branch ducts 61a and 61b to greatly decrease the speed of the air flowing in the upper spaces of the water seal chambers 24i and 24i toward the feed and discharge zone B. Accordingly, splashing of the sealing water can be prevented.

  • An exhaust duct 52 is connected to a predetermined place of the stationary hood 51.
  • a waste heat recovery zone D may be provided in a part of the cooling zone C in Embodiment 1, as shown in Fig. 15 .
  • heat is recovered from the hot air which is used for cooling sintered ore, and then, the air is sent to the stationary circular duct 31 again for cooling.
  • Embodiment 1 has the following structure additionally to the above.
  • the air damper 81 is in a closed state in the material feed zone B to close the connection air duct 26, as shown in Fig. 1 , so as to prevent the cooling air from flowing out. Moreover, the air damper 81 is in an open state in the cooling zone C to open the connection air duct 26, as shown in Fig. 2 , so as to supply the cool-air box 12 with the cooling air.
  • the air damper 81 is opened and closed automatically under mechanical or electrical control.
  • a butterfly type air damper is used for the air damper 81 in Embodiment 1. The invention, however, is not limited to the above. It is possible to use a swing type air damper or another type air damper.
  • Such a structure causes the movable air path 25 and the upper spaces of the water seal chambers 24i and 24i to form an entirely communicated circular duct having no partition in the circumferential direction and an operation of the air damper 81 to properly prevent air leakage in the feed and discharge zone B. Accordingly, no difference in pressure between the feed and discharge zone B and the cooling zone C is made, so that no air flows in the movable air path 25 from the cooling zone C toward the feed and discharge zone B.
  • the movable air path 25 and the upper spaces of the water seal chambers 24i and 24i are formed into an entirely communicated circular duct having no partition in the circumferential direction while the pressure in the movable air path 25 and the upper spaces of the water seal chambers 24i and 24i is the same in the circumferential direction.
  • the air damper 81 provided in the connection air duct 26 is easy to be maintained and controlled more than the conventional labyrinth sealing part (the dead plate 42 and the labyrinth sealing plates 43a, 43b and 43c), so that performance in maintenance is excellent.
  • the middle air duct 38 can be provided also on an entrance side and an exit side of the feed and discharge zone B and on an exit side of the waste heat recovery zone D although it cannot be provided in the above places conventionally due to the dead plate 42. This allows the cooling performance to be improved while the scale of the system is kept as it is.
  • the heat recovery is performed for the air having high temperature due to cooling of sintered ore, and then, the air is fed again as the cooling air.
  • This often causes a foreign matter such as dust of the sintered ore to be intruded into the cooling air. Intrusion and accumulation of such a foreign matter in the circular water seal chambers 24a and 24b causes deterioration of the water sealing performance due to damage of the water sealing plates 34a and 34b and the like.
  • a foreign matter intrusion prevention plate (an obstacle plate) 85 which is for preventing the foreign matter intruded into the cooling air from intruding into the circular water seal chambers 24a and 24b from a space between upper ends of the inner plates 22a and 23a of the circular water seal chambers 24a and 24b and the fitting flange 35 through the upper spaces of the water seal chambers 24i and 24i, in upper parts of the upper spaces of the water seal chambers 24i and 24i, as shown in Fig. 4 .
  • the foreign matter intrusion prevention plate 85 can be similarly provided in a place other than the waste heat recovery zone D, of course, in the case where a foreign matter is intruded into the cooling air to be supplied.
  • a sucking device (not shown) for sucking and collecting the foreign matter from the circular water seal chambers 24a and 24b.
  • the sucking device may be provided in the feed and discharge zone B where a room is left.
  • the side wheel 5b is arranged so that it can be adjusted by means of a screw jack in Embodiment 1. This allows a position of the side wheel 5b to be adjusted even during running, and thereby, rotation of the circular water seal chambers 24a and 24b to be kept at a high degree of circle. The water sealing performance is thus prevented from being lowered.
  • Embodiment 2 is basically similar in structure to Embodiment 1 mentioned above.
  • the movable air path 25 is made to communicate in the circumferential direction and the partition plate having been conventionally provided in the movable air path 25 is removed.
  • a part of the conventional partition plate 47 is notched so that a function of guiding the cooling air would be left while the movable air path 25 would be made to communicate in the circumferential direction in Embodiment 2.
