Problems solved by technology
[0004] In such an atmosphere replacement chamber provided with a plurality of replacement chambers, the replacement and discharge of the inert gas have been performed independently for each replacement chamber conventionally. Therefore, there is a problem that the amount of the used inert gas increases and the production cost increase

Embodiment Construction
[0031] Hereinafter, the atmosphere replacement device 1 according to the embodiment of the present invention will be described with reference to the drawings. The atmosphere replacement device 1 is installed on the inlet side and / or the outlet side of a continuous firing furnace such as a roller kiln, and is used to stabilize the atmosphere in the continuous firing furnace.
[0032] like figure 1 As shown, the atmosphere replacement device 1 has: a tunnel part 2; a shutter 4, which divides the tunnel part 2 into a plurality of replacement chambers 3 (refer to figure 2 ); a shutter elevating mechanism 5 for moving the shutter 4 in the vertical direction; and a conveying line for conveying the to-be-fired object from the entrance to the exit of the tunnel portion 2 . The shutter elevating mechanism 5 is not particularly limited, and for example, a pressing device using a cylinder can be used, and the shutter 4 can be opened and closed by vertically expanding and contracting th...

An atmosphere replacement method and device, and a firing furnace with the atmosphere replacement device. The atmosphere replacement device has a tunnel part, a shutter, a shutter lifting mechanism and a conveying line. The replacement chamber has a first replacement chamber arranged on the entrance side of the tunnel part and a second replacement chamber arranged on the exit side of the tunnel part. The shutter has a The first shutter on the inlet side of the first replacement chamber, the second shutter arranged between the first replacement chamber and the second replacement chamber, and the third shutter arranged on the outlet side of the second replacement chamber, the second replacement chamber has The atmospheric gas supplied from the supply source of the atmospheric gas is injected into the first gas injection port in the second replacement chamber and the first gas discharge port from which the atmospheric gas is discharged from the second replacement chamber. Atmospheric gas is injected into the second gas injection port in the first replacement chamber and the second gas discharge port for discharging the atmospheric gas from the first replacement chamber, and the atmosphere replacement device has a connecting part connecting the first gas discharge port and the second gas injection port .
Description
technical field [0001] The present invention relates to an atmosphere replacement device, an atmosphere replacement method, and a firing furnace with an atmosphere replacement device provided with the atmosphere replacement device. Background technique [0002] In a continuous firing furnace such as a roller hearth kiln, an atmosphere replacement chamber may be provided on the inlet side and / or the outlet side of the firing furnace for atmosphere control. In such an atmosphere replacement chamber, the atmosphere inside the replacement chamber is controlled by replacing the air inside the replacement chamber with an inert gas such as nitrogen, for example. [0003] However, it is well known that in such an atmosphere replacement chamber, in order to more efficiently and strictly control the atmosphere, the interior of the atmosphere replacement chamber is divided into a plurality of replacement chambers by shutters. In such an atmosphere replacement chamber, the atmosphere i...
