〔産業上の利用分野〕
この発明は、穀物乾燥機における熱風発生装置に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a hot air generator in a grain dryer.
〔従来技術及び発明が解決しようとする課題〕穀物乾燥
機において、前後に長い熱風室の一側にバーナを配設し
て穀物流下通路をはさんで他側の吸引ファンによる吸引
風を起風せしめて、バーナ火炎と外気とを混合せしめる
形態かあり、バーナは吸引風の通過しうる箱型の風胴内
に収容されてその111I側には手記バーナ火炎と尋人
外気風との混合を促進すべきダク1〜を接続している。[Prior art and the problem to be solved by the invention] In a grain dryer, a burner is arranged on one side of a long hot air chamber in the front and back, and a suction fan on the other side creates suction air across the grain flow passage. At the very least, there is a form in which the burner flame and outside air are mixed.The burner is housed in a box-shaped wind barrel through which suction air can pass, and on the 111I side there is a box-shaped wind barrel that allows the burner flame to mix with outside air. Connecting the ducts 1 to 1 to be promoted.
一方、バーナは瞬間着火、消火の有利な気化バーナ形態
が普及している。On the other hand, vaporizing burners, which are advantageous for instant ignition and extinguishment, are becoming popular.
ところで、従来はバーナを]−記風胴の中央部に配設し
て、尋人外気風を該バーナの背後からバーナ外周を迂回
して、前方のダクh部に向けて略均等に通過させる形態
としている。By the way, in the past, a burner was disposed in the center of the recorder cylinder, and outside air was passed from behind the burner, bypassing the outer periphery of the burner, and passing almost evenly toward the duct h section in front. It is in the form of
このため、燃焼筒内で燃焼する火炎と外気との混合が充
分でない。For this reason, the flame burning within the combustion cylinder and the outside air are not sufficiently mixed.

路Aに形成する穀物乾燥機に才9ける熱風発生装ji;
の構成とする。This invention attempts to eliminate the drawbacks listed in -1-, and the burner 6 that burns the vaporized fuel jetted forward from the combustion disk 27 is biased toward one side of the left and right sides in the wind cylinder 7 that communicates with the hot air chamber. At a position immediately behind the burner 6 in the wind cylinder 7, an outside air introduction D 46 is opened, and a space that is wide on the side of the burner 6 in the wind 117 is formed as a detour A for the introduced air. Hot air generator for grain dryer;
The structure is as follows.
燃焼状態にあるバーナ6の直後方から導入される外気は
、一部がバーナ6と風胴7の内壁との狭い空間部を抜け
て前方に移行し、他はバーナ6の側方空間部で流速を弱
められつつ迂回しながら同様に前方に移行する。従って
バーナ6の前方においては流速の一様でない外気が混在
して、回転気化筒等による影響を受けて旋回流が生じ、
バーナにて発生する火炎との混合が良好となる。A portion of the outside air introduced from immediately behind the burner 6 in the combustion state passes through the narrow space between the burner 6 and the inner wall of the wind cylinder 7 and moves forward, and the rest passes through the side space of the burner 6. Similarly, it moves forward while detouring while the flow speed is weakened. Therefore, in front of the burner 6, outside air with an uneven flow rate is mixed, and a swirling flow is generated due to the influence of the rotating carburetor cylinder, etc.
Good mixing with the flame generated in the burner.

works. Here, the burner 6 burns in response to the fuel supply amount determined based on the outside temperature condition and manual filling amount setting, that is, the valve on time transmission, and the nozzle 3
The fuel supplied from the zero end drips onto the circumferential surface of the diffuser 32 and moves along the inner circumferential surface of the vaporization tube 26 along with the combustion air blown by the fan 21 while being atomized.

、バーナ火炎との混合が良好となる。The combustion flame enters the ducts I to 44, while the outside air generated by the suction fan 9 and entering from the mesh frame 46 of the wind barrel 7 passes through the outer periphery of the burner 6, enters the duct 44, and joins the flame. At the very least, it turns into hot air. At this time, part of the outside air passes through the left side of the burner 6, which has a narrow space, and the other part passes through the right side of the burner 6, which has a wide space. Therefore, the flow velocity of the outside air differs between the left and right sides of the burner 6, and together with the rotation of the vaporizing cylinder 23, a swirling flow is likely to occur during the transition to the front of the burner 6, and the mixing with the burner flame is good. Become.
