品にバラツキを生ずる欠点があつた。Problems to be solved by conventional techniques and inventions To smoke tiles, the tile base is fired at 1,000 to 1,100 degrees Celsius, cooled to the appropriate smoking temperature of approximately 900 degrees C, and then the inside of the furnace is isolated from outside air. This is done by filling the roof tiles with a hydrocarbon-based fuming gas and depositing thermally decomposed carbon on the surface of the roof tiles.In order to form a carbon film of sufficient thickness, It is necessary to keep the tiles at an appropriate temperature for smoking, and to constantly supply new smoking gas to the surface of the tiles. However, in the past, a certain amount of fuming gas was charged into the furnace and gradually discharged from a narrow chimney opening, causing the filled fuming gas to flow and come into contact with the roof tiles. However, the flow of fuming gas is very small and it does not come into sufficient contact with the roof tiles, so in order to form a carbon film of the required thickness, it is necessary to fill the furnace with a large amount of fuming gas. It was necessary to increase the concentration of fuming gas. However, this method is not only uneconomical as most of the fuming gas filled in the furnace is discharged unused.
Air pollution caused by exhaust gas was becoming a problem. In addition, if a large amount of fumigating gas is filled, the temperature inside the furnace will drop and thermal decomposition will not take place actively, and furthermore, the flow of fumigating gas within the furnace will be uneven, causing variations in the product. There were flaws.

The purpose is to provide a device.

ガスの濃度が低下する効果を奏する。Structure, operation, and effect of the invention The present invention forms a window hole in a housing, and also provides two door plates that open and close the window holes alternately, and a rotating blade is provided on the inner surface of one door plate, and a rotary blade is provided on the outer surface of one of the door plates. The drive motor for each of the rotary blades is installed, and when the tiles are fired at a high temperature, the window hole is closed by the other door plate, and during the smoking process at a relatively low temperature, the window hole is closed by one door plate. By blocking the holes and stirring the smoldering gas in the room with the rotary blades attached to the inner surface, the rotor blades are not exposed to high temperatures and burnt out, and the smoldering gas is forced to flow. The carbon film is evenly contacted with the surface of the tiles, and the filled fuming gas is effectively used to uniformly form a carbon film of the desired thickness throughout the smoking chamber. It is only necessary to fill it with fumigation gas, which is economical, does not lower the temperature inside the fumigation chamber, and has the effect of reducing the concentration of exhaust gas.
