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、穀物乾燥機の排気口または排塵機の排塵口から排出される排気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気口から排出される排気には、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気にともなって多くの塵埃が排出される。
【０００３】
従来、一般農家の穀物乾燥機や小規模施設の穀物乾燥機にあっては、穀物乾燥機の排気口に接続したダクトを屋外に出して、排気口から塵埃を含んだ排気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、近年、一般農家においても、穀物乾燥機の排気口から排出される排気に含まれる塵埃による周辺の環境悪化を避けるため、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いて、湿式または乾式の集塵装置が種々開発されている。
【０００５】
例えば、従来の湿式サイクロン方式の集塵装置がそれであるが、この湿式サイクロン方式の集塵機にあっては、排気の旋回部、それに連通するサイクロン部および湿式の集塵部によって構成されているので、かなり広い設置場所を要するとともに、装置自体の大きさから収集した汚泥状の塵埃の除去掃除作業も労力を要していた。また、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とされている。
【０００６】
そこで、本発明は、穀物乾燥機からの排気を導入して塵埃を分離する集塵部分をユニット化して集塵ユニットとするとともに、それと水槽とを組み合わせるだけで、湿式であっても簡素でかつ小型に構成でき、しかも、水槽に貯留した水を循環使用することにより水の使用量を少なくできるうえ、水槽から集塵ユニットを完全に分離できて、水槽に貯まって塵埃の除去清掃作業も容易に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。
【０００７】
【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、穀物乾燥機から排出される排気に混在する塵埃を分離して収集する集塵装置であって、上面が開放した水槽と、この水槽の上部に載置する集塵ユニットとで構成されており、上記集塵ユニットは、穀物乾燥機からの排気を下向きに導入する排気導入筒の開口端にその開口端より大径の円板を対向させてあり、この円板の上面中心部には噴水ノズルを近接対向させて水飛沫生成部を構成するとともに、水飛沫生成部の周囲は上面を閉じかつ下面を開放した円筒で囲んで水飛沫生成部の周囲に水飛沫と排気との混合部を形成して、水槽の内面と混合部を形成する円筒との間には除塵された排気の排気路を形成し、水飛沫と排気との混合部の上部周面には外気に通じる排気口を形成したことを特徴とするものである。
【０００８】
また、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、集塵ユニットの噴水ノズルには、水槽内の少なくとも水飛沫生成部の下端より低水位に貯留されている水を水槽内に配置した水中ポンプにより圧送する構成と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、水槽の内面と水飛沫生成部の排気路を形成する部分はともに円筒形であって、水槽の内面と水飛沫生成部の排気路を形成する部分でその全周にわたって等間隔の排気路を形成していることを特徴とするものである。
【００１０】
本発明に係る請求項４の穀物乾燥機用集塵装置は、請求項１、２または３の構成において、集塵ユニットの混合部の外気に通じる排気口には遮水性の通気フィルタを装填したことを特徴とするものである。
【００１１】
本発明に係る請求項５の穀物乾燥機用集塵装置は、請求項１、２、３または４の構成において、水槽の上端は全周にわたって受け段部を成し、集塵ユニットにはその両側に張り出しかつ排気路の通気を妨げない支持アームを設けてあって、水槽の受け段部に集塵ユニットの支持アームを係止する構成であることを特徴とするものである。
【００１２】
【発明の実施の形態】
図１は本発明に係る穀物乾燥用集塵装置の一実施の形態を示す縦断正面図、図２は同上平面図、図３は同上水槽を破断して示す正面図、図４は同上分解斜視図、図５は本発明に係る穀物乾燥機用集塵装置を穀物乾燥機の排気口に接続して使用する態様を示す正面図である。
【００１３】
図１ないし図４において、１は穀物乾燥機用集塵装置である。この穀物乾燥機用集塵装置１は、上面が開放した水槽２と、この水槽２の上部に載置する集塵ユニット３とで構成されている。水槽２は上方に向かってやや拡径した円筒形のものであり、外面に補強リブ等が形成されることがあっても内面は円筒形であることが好ましい。水槽２の上端は全周にわたって受け段部４を成している。
【００１４】
上記集塵ユニット３は、穀物乾燥機からの排気を下向きに導入する排気導入筒５の開口端にその開口端より大径の円板６を対向させてあり、この円板６の上面中心部には噴水ノズル７を近接対向させて水飛沫生成部８を構成している。水飛沫生成部８の周囲は上面を閉じかつ下面を開放した円筒９で囲まれていて、水飛沫生成部８の周囲に水飛沫と排気との混合部１０を形成している。そして、水槽２の内面と混合部１０を形成する円筒９との間に、除塵された排気の排気路１１が形成されている。
【００１５】
水槽２内には水中ポンプ１２が配置され、この水中ポンプ１２と前記噴水ノズル７とはその接続管１３と可撓性の接続管１４によって接続されており、可撓性の接続管１４はその途中がコネクタ１５により着脱自在となっている。水槽２内には水が所定水位Ａを保つように貯留されるが、その水位Ａは水中ポンプ１２が沈みかつ少なくとも水飛沫生成部８の下端より低水位である。
【００１６】
水槽２の内面と水飛沫生成部８の排気路１１を部分は円筒９であり、かつ水槽２の内面も円筒形であるから、排気路１１はその全周にわたって等間隔を成している。
【００１７】
水飛沫と排気との混合部１０の上部周面には外気に通じる排気口１６が形成されており、この排気口１６には遮水性の通気フィルタ１７が装填されている。なお、通気フィルタ１７は交換可能である。
【００１８】
本発明に係る穀物乾燥機用集塵装置１は、前記のように、水槽２と集塵ユニット３とで構成されるが、集塵ユニット３にはその両側に張り出しかつ排気路１１の通気を妨げない支持アーム１８、１８を設けてあって、水槽２の受け段部４に集塵ユニット３の支持アーム１８、１８を係止するように構成されている。すなわち、集塵ユニット３は水槽２の上方からその上端部に載置し、排気導入筒５の上端と図５の実施の態様では穀物乾燥機１９の排気口２０とをダクト２１により接続し、さらに、噴水ノズル７と水中ポンプ１２とを可撓性の接続管１４によって接続して穀物乾燥機用集塵装置１を構成する。
【００１９】
図５に示す穀物乾燥機１９の排気口２０からは、穀物層を通過した排気が圧送排気としてダクト２１を通り、穀物乾燥機用集塵装置１にその排気導入筒５から集塵ユニット３内に白抜き矢印で示すように導入されるが、集塵ユニット３においては、排気導入筒５の開口端に対向する円板６により水飛沫生成部８が形成されていて、その円板６の上面中心部には、矢印で示すように、水槽２内の水が水中ポンプ１２により噴水ノズル７から勢いよく噴射されるので、混合部１０では排気と水飛沫とが激しく撹拌を繰り返して塵埃が分離される。そして分離された塵埃は水飛沫とともに水槽２内に流下して貯留され、塵埃を分離された排気は排気路１１を通って水槽２の上端から排出されるが、その一部は混合部１０の排気口１６から通気フィルタ１７を通って排出される。なお、混合部１０に排気口１６を設けることにより一部の排気が排気口１６から外気に排出されることで、排気の風速を遅くし、水と塵埃との混合時間を長く取れることと、一部の排風を上昇させて混合部１０で渦を巻くことで、水飛沫との混合を均等化することができ、水飛沫による塵埃の分離効果を向上させることができる。
【００２０】
水槽２内に貯留した水は繰り返し循環して使用されるが、蒸発や飛散による減少により所定の水位より低下したときは適宜水を補給する。なお、そのために水槽２に水の補給口（図示せず）を設けてもよい。
【００２１】
水槽２内に貯まった塵埃は、作業の終了後に適宜排除するが、その排除作業にあたっては、図５に示すように、水槽２から集塵ユニット３を取り外せば、水槽２の清掃作業を容易に行うことができる。また、水槽２の清掃作業後は、水槽２に集塵ユニット３を容易に装着できることは前述のとおりである。
【００２２】
図５に示す実施の態様では、本発明に係る穀物乾燥機用集塵機１を穀物乾燥機１９の排気口２０に接続して使用しているが、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２２の排塵口に接続して使用することができるし、排気口２０と排塵機２２の排塵口の両方を接続した使用態様とすることも可能である。また、本発明に係る穀物乾燥機用集塵機１は、そのままで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。
【００２３】
【発明の効果】
本発明によれば、穀物乾燥機からの排気を導入して塵埃を分離する集塵部分をユニット化して集塵ユニットとするとともに、それと水槽とを組み合わせるだけで、湿式であっても簡素でかつ小型に構成でき、しかも、水槽に貯留した水を循環使用することにより水の使用量を少なくできるうえ、水槽から集塵ユニットを完全に分離できて、水槽に貯まって塵埃の除去清掃作業も容易にできる穀物乾燥機用集塵装置を提供することができる。
