うにしたものも２，３ある。(Prior art) The track guide pallet type sintering machine shown in FIG.
The raw material powder ore A is charged onto the top, and the powder ore A is ignited while passing under the ignition furnace d provided with the ignition burner c, which opens below the pallet conveyor b. Sintering is performed from the upper layer to the lower layer by air sucked by the main duct f through the wind box e. In order to reduce the fuel consumption rate in the ignition furnace d,
It is said that it is better to keep the pressure inside the ignition furnace d at a negative pressure of about -0.5 to -1.0 mmH 2 O, but if the pressure inside the ignition furnace d becomes negative, as shown in Figure 3, A small space t is provided between the ignition furnace d and the upper side wall g' in preparation for the meandering of the pallets, so air enters the furnace through the space t and the surface of both ends of the pallets is heated. This results in poor ignition of the yoke, which causes an inconvenience in that the fuel consumption rate increases in order to maintain the temperature inside the furnace. Despite this, there are a surprising number of sintering machines that do not have any means for preventing the atmospheric air from entering the furnace, but there are a few that are equipped to prevent atmospheric air from entering the furnace.

A seal receiving plate j is provided between the flanges h 1 and h 2 that connect the lower sidewall g″ to the endless pallet body that rolls on the top, and supports the lower ends of both sleeves d′ and d′ of the ignition furnace d. A seal frame l is provided on the frame k, and a seal plate l' that is in sliding contact with the seal receiving plate j is further provided at the lower end of the seal frame l.

A protrusion 4 protrudes like a strip from the side surface of the pallet passing below the ignition furnace d while being guided by a truck s.
An elastic curved portion (flexible portion) 5 of a seal plate 6 fixed to the lower end of the seal frame 1 vertically installed on the
Since it enters the ignition furnace 1 in sliding contact with the pallet g, the entrance to the space t between both sleeves d' of the ignition furnace d and the pallet g is always connected to the seal frame 1, the seal plate 6, and the elastic curved part 5. Since the ignition furnace 1 is completely shut off,
Even if the inside becomes negative pressure and the pallet g meanders slightly from side to side while it is moving, the flexible portion 5 of the seal plate is in sliding contact with the protrusion 4, so air is not sucked into the space t. There is no situation where I would go.
