Description

【0001】
【発明の属する技術分野】
本発明は、穀物乾燥機と併用して、穀物乾燥機の排風口または排塵機の排塵口から排出される排風中の細塵を分離して収集する穀物乾燥機用集塵装置に関する。
【0002】
【従来の技術】
穀物を通風乾燥する穀物乾燥機において、被乾燥穀物層を通過して排風口から排出される排風には、藁屑、穀物の殻、穎、毛茸、泥あるいは埃などの塵埃が多く含まれている。また、穀物乾燥機には、被乾燥穀物に混入している塵埃を除去する排塵機を付設することもあるが、この排塵機の排塵口からも排風にともなって多くの塵埃が排出される。
【0003】
従来、一般農家や小規模の穀物乾燥施設等にあっては、穀物乾燥機の排風口に接続したダクトを屋外に出して、排風口から塵埃を含んだ排風をそのまま屋外に排出しているのが実情である。
【0004】
【発明が解決しようとする課題】
ところで、穀物乾燥機の排風口から排出される排風を、ダクトで屋外に導いて排出すると、塵埃による周辺の環境悪化が避けられないので、近年、一般農家においても、穀物乾燥機に併設して用いる集塵装置の需要が高まっており、その需要に応じるべく、湿式または乾式で種々の集塵装置が開発されている。
【0005】
例えば、乾燥施設においては実開昭63−73133号のようなシャワー方式の湿式集塵装置がそれであるが、このシャワー方式の湿式集塵機にあっては、集塵効率を上げるためシャワー室の面積を大きくとる必要があることから、かなり広い設置場所を要するものである。また、一般農家用にコンパクト化された集塵装置では、特開平8−303951号のような湿式の集塵装置も公知であるが、このような小型の湿式集塵装置においては、少ない面積内で集塵効率を上げるためノズルから循環水を噴霧している。噴霧される循環水は穀物乾燥機からの塵埃とゴミを徐々に含んでくるものであるから、いずれ循環水を噴霧するノズルがつまり集塵効率が低下し、水中ポンプ本体が故障することがある。
【0006】
乾式サイクロン方式の集塵装置は、簡素で比較的小型に構成できるところから、一般農家や小規模の穀物乾燥施設等においても容易に設備可能であるが、特に細塵の除去率が低いため、周辺の環境保持が十分達成できないことが問題視されている。
【0007】
そこで、本発明は、噴霧除塵室と集塵貯水室を上下に一つにまとめて湿式であっても簡素かつ小型に構成することができ、しかも集塵貯水室内の水を循環使用することにより水の使用量を少なくでき、水を噴霧させるためのノズルを使用しないうえ、噴霧除塵室内において穀物乾燥機から圧送される排風の導入口を遮る霧膜を形成させることにより、塵埃、特に細塵の除去率を大きく向上させることができる穀物乾燥機用集塵装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
上記目的を達成するための本発明に係る請求項1の穀物乾燥機用集塵装置は、穀物乾燥機の排風口または穀物乾燥機に付設した排塵機の排塵口に接続して、穀物乾燥機の排風口または排塵機の排塵口から排出される排風中の細塵を分離して収集する集塵装置であって、上段に設けた噴霧除塵室と、その下段に設けた集塵貯水室とで構成し、上段の噴霧除塵室には、穀物乾燥機から圧送される排風の導入口に対向させて霧膜生成板を配置し、この霧膜生成板の前面側には噴水ノズルを近接対向させてあるとともに、下段の集塵貯水室内には水中ポンプを配置し、この水中ポンプの送水管は可撓性管であって上記噴水ノズルの基端に着脱自在に接続して、下段の集塵貯水室から汲み上げた水を上記霧膜生成板に吹き付けて噴霧除塵室内に排風の導入口を遮る霧膜を形成させるように構成し、前記上段の噴霧除塵室とその下段の集塵貯水室との間には送水管の引出口を形成してあり、前記噴水ノズルの基端からの送水管の先端を外して水中ポンプに接続されている送水管を引出口から外部に引き出して水中ポンプにより集塵貯水室内の水および塵埃を排出することができるように構成したことを特徴とするものである。
【0009】
本発明に係る請求項2の穀物乾燥機用集塵装置は、請求項1の構成において、霧膜生成板は、その水の吹き付け面を緩円錐面としてことを特徴とするものである。
【0010】
本発明に係る請求項3の穀物乾燥機用集塵装置は、請求項1または2の構成において、霧膜生成板は、水の吹き付け圧により前後に振動または揺動するように構成されていることを特徴とするものである。

また、図4は本発明に係る穀物乾燥用集塵装置の他の実施の形態を示す断面図、図5は同上要部の断面図、図6は同上要部の作用を表した断面図、図7は本発明に係る穀物乾燥用集塵装置のさらに他の実施の形態を示す断面図である。
【0014】
図1および図2において、1は穀物乾燥用集塵装置である。この穀物乾燥用集塵装置1は、上段に噴霧除塵室2を備え、かつ下段に集塵貯水室3を備えて構成されている。上段の噴霧除塵室2には、穀物乾燥機から圧送される排風の導入口4に対向させて霧膜を形成させるための霧膜生成板5を配置してあり、この霧膜生成板5の前面側には噴水ノズル6を近接対向させてある。また、下段の集塵貯水室3内には水中ポンプ7が配置されており、水中ポンプ7の送水管8は上記噴水ノズル6に接続されている。送水管8は可撓性管であって、その先端は噴水ノズル6の基端に着脱自在である。9,10はその接続コックである。噴霧除塵室2の上面にはフィルタ11を備えた排風口12が開口している。13は送水管8の引出口である。
【0015】
本発明に係る穀物乾燥機用集塵装置1は、図3に示すように、穀物乾燥機14の排風口15にダクト16を介して排風の導入口4を接続して使用する。17は熱風室、18はバーナ、19は穀物乾燥層、20は排風室、21は吸引送風機である。
【0016】
穀物乾燥機14の排風口15からは、吸引送風機21により排風が圧送風として穀物乾燥機用集塵装置1にその排風導入口4から噴霧除塵室2内に導入されるが、噴霧除塵室2内には、排風導入口4に対向して配置された霧膜生成板5に、集塵貯水室3から水中ポンプ7で汲み上げられた水が吹き付けられ、噴霧除塵室2内には排風の導入口4を遮るように霧膜が形成される。このため、導入される排風中の塵埃は、この霧膜によって細塵までが効率よく除去されるが、霧膜を通り過ぎた塵埃があっても噴霧除塵室2内に充満する霧によって残らず除去され、塵埃が除去された清浄な排風は排風口12から外部に放出される。
【0017】
上記のように噴霧除塵室2内で除去された塵埃は、霧膜および霧による水滴とともに下段の集塵貯水室3に収集される。集塵貯水室3内の水は霧膜の形成に循環使用されるが、集塵貯水室3内の水位が低下したときは外部から自動的にまたは適宜補給する。
【0018】
集塵貯水室3内に塵埃が所定量まで堆積した場合や必要に応じて塵埃の排出をする場合、あるいは排水をする場合には、噴水ノズル6の基端の送水管8の先端を接続している接続コック9,10を外して、図2に示すように、水中ポンプ7に接続されている送水管8を引出口13から外部に引き出し、水中ポンプ7により集塵貯水室3内の水および塵埃を、効率よくしかも容易に排出することができる。
【0019】
本発明に係る穀物乾燥機用集塵装置1において、霧膜生成板5は、図4ないし図5に示すように、その水の吹き付け面5aを緩円錐面とすれば、図6に示すように、霧膜が噴霧除塵室2内の後方に向かって拡散させることができ、霧膜の表面積を大きくすることで、より塵埃の除去作用効率を向上させることができる。また、霧膜が噴霧除塵室2の前方から後方に向かって高速で移動するため、噴霧除塵室2内に前方から後方に向かっての風の流れを形成し、穀物乾燥機14に穀物乾燥機用集塵装置1を付設した事で発生している風の流れの抵抗を緩和することができる。
【0020】
また、図7に示すように、霧膜生成板5を弾性体5bによって支持するなど、水の吹き付け圧により前後に振動または揺動するように構成することにより、変化に富んだ霧膜を形成して、塵埃の除去効率をさらに向上させることができる。
【0021】
図示の実施の形態において、霧膜生成板5を高速回転するものとすることにより、形成される霧膜にさらに変化を起こさせることができ、それによって塵埃の除去効率の向上を図ることが可能である。なお、その構成については図示を省略する。
【0022】
図示の実施の形態においては、本発明に係る穀物乾燥機用集塵機1を穀物乾燥機14の排風口15に接続して使用する態様を例示しているが、本発明に係る穀物乾燥機用集塵機1は穀物乾燥機1に付設した排塵機の排塵口に接続して使用することができる。また、本発明に係る穀物乾燥機用集塵機1のほか、他の穀類調製機の集塵用としても使用することができるものである。

In FIG. 1 and FIG. 2, 1 is a dust collector for grain drying. The grain drying dust collecting apparatus 1 includes a spray dust removing chamber 2 in an upper stage and a dust collecting water storage chamber 3 in a lower stage. In the upper spray dust removal chamber 2, there is disposed a mist film generating plate 5 for forming a mist film so as to face the inlet 4 of the exhausted air pumped from the grain dryer. A fountain nozzle 6 is placed in close proximity to the front surface of the fountain. A submersible pump 7 is disposed in the lower dust collection water storage chamber 3, and a water pipe 8 of the submersible pump 7 is connected to the fountain nozzle 6. The water supply pipe 8 is a flexible pipe, and the tip thereof is detachable from the base end of the fountain nozzle 6. Reference numerals 9 and 10 denote connection cocks. An air exhaust port 12 having a filter 11 is opened on the upper surface of the spray dust removal chamber 2. Reference numeral 13 denotes an outlet of the water pipe 8.
[0015]
As shown in FIG. 3, the dust collector 1 for grain dryer according to the present invention is used by connecting the exhaust outlet 15 of the grain dryer 14 via the duct 16 to the exhaust outlet 15 of the grain dryer 14. Reference numeral 17 is a hot air chamber, 18 is a burner, 19 is a grain drying layer, 20 is an exhaust chamber, and 21 is a suction blower.
