Description

【０００１】
【発明の属する技術分野】
本発明は、微生物の力を利用して生ごみの分解処理を行う生ごみ処理装置に関するものである。
【０００２】
【従来の技術】
従来から微生物による生ごみの分解作用を利用した生ごみ処理装置が知られている。この生ごみ処理装置は、微生物の分解作用を促進するため、空気を供給し、且つバイオチップと生ごみの混合性を良くすることが求められている。このため、従来にあっては、バイオチップと称する木質細片のような担体と生ごみを撹拌しており、この撹拌手段として、回転軸１に螺旋状をした撹拌羽根２を形成したものが特開平８−８４９８０号公報などにより知られている。この特開平８−８４９８０号公報に示された撹拌羽根は、図７に示すように、処理槽４内に回転自在に架設した回転軸１が螺旋状をした撹拌羽根２の中心軸となっており、回転軸１と撹拌羽根２とは連結用羽根板５により連結してあり、更に、撹拌羽根２は、回転軸１の一端側から中央位置に向けて右巻螺旋状をした片側の撹拌羽根２ａと、回転軸１の他端側から中央位置に向けて左巻螺旋状をした他の片側の撹拌羽根２ｂとの２つの分離された撹拌羽根２により構成してある。そして、撹拌羽根２は回転軸１が回転すると、右、左の螺旋巻の作用で、バイオチップが処理槽４両側面から中央部に集まり、そこで、処理槽４内面に沿って上昇し、両側面に分散する働きにより空気を供給し且つ生ごみとバイオチップとの混合を行っている。
【０００３】
ところが、上記のような生ごみ処理装置においては、回転軸の回転方向を逆にした場合、バイオチップが中央から処理槽４の両側面に向かって移動し、やがて処理槽４の側面を押すようになり、その力で処理槽４側面を破損させるおそれがあり、また、処理槽４の両側面には螺旋状をした撹拌羽根２の先端のみが近いだけであり、このため処理槽の側面にバイオチップがこびり付いて生ごみの分解処理性能が低下するという問題がある。
【０００４】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、回転軸の回転方向を逆にしても処理槽の側面が破損するおそれがなく、また、処理槽の側面にバイオチップがこびり付くのを防止して生ごみの分解処理性能を向上させることができる生ごみ処理装置を提供することを課題とするものである。
【０００５】
【課題を解決するための手段】
上記課題を解決するために本発明に係る生ごみ処理装置は、駆動手段によって回転する撹拌羽根２を内蔵した生ごみ処理装置であって、回転軸１の一端側から中央位置に向けて片側の撹拌羽根２ａを右巻き螺旋状に設けるとともに、回転軸１の他端側から中央位置に向けてもう一方の撹拌羽根２ｂを左巻き螺旋状に設け、回転軸１の軸方向と平行な方向の処理槽の一方の側面に対向する右巻螺旋状の撹拌羽根２ａ部分に処理槽４の一方の側面付近を撹拌するためのバー３を上記処理槽４の一方の側面側に向けて突出して設け、回転軸１の軸方向と平行な方向の処理槽の他方の側面に対向する左巻螺旋状の撹拌羽根部２ｂ分に処理槽４の他方の側面付近を撹拌するためのバー３を上記処理槽４の他方の側面側に向けて突出して設けて成ることを特徴とするものである。このような構成とすることで、回転軸１を逆回転した場合に、右巻螺旋状の撹拌羽根２ａ、左巻螺旋状の撹拌羽根２ｂにより中央部から両側にバイオチップが移動するが、処理槽４の両側面付近側に移動したバイオチップが、右巻螺旋状の撹拌羽根２ａ部分に処理槽４の一方の側面側に向けて突出したバー３や左巻螺旋状の撹拌羽根２ｂ部分に処理槽４の他方の側面側に向けて突出したバー３により持ち上げられて処理槽４の側面に力を与えることがなく、また、処理槽４の側面にバイオチップが付着することがないものである。
【０００６】
また、右巻螺旋状の撹拌羽根２ａの先端から少し左巻螺旋状の撹拌羽根２ｂ側にずれた位置にバー３が設けてあり、左巻螺旋状の撹拌羽根２ｂの先端から少し右巻螺旋状の撹拌羽根２ａ側にずれた位置にバー３が設けてあることが好ましい。このような構成とすることで、螺旋状をした撹拌羽根２ａ、２ｂの各先端で処理槽４の側面付近の一部を撹拌するとともに、螺旋状をした撹拌羽根２ａ、２ｂの各先端から少し処理槽４の側面から離れる方向にずれた位置で側面側に移動してきたバイオチップを持ち上げ、また、側面にバイオチップが付着するのを防止することができるものである。
【０００７】
また、右巻螺旋状の撹拌羽根２ａの先端の処理槽４の一側面と対向する面に処理槽４の一側面側に向けて突出するバー３が設けてあり、左巻螺旋状の撹拌羽根２ｂの先端の処理槽４の他側面と対向する面に処理槽４の他側面側に向けて突出するバー３が設けてあることが好ましい。このような構成とすることで、処理槽４の両側面付近側に移動したバイオチップが両側面に最も近い撹拌羽根２ａ、２ｂの各先端においてバー３により効果的に持ち上げて処理槽４の側面に力を与えないようにでき、また、処理槽４の側面にバイオチップが付着することがないものである。
【０００８】
また、右巻螺旋状の撹拌羽根２ａの処理槽４の一側面側の先端と左巻螺旋状の撹拌羽根２ｂの処理槽４の他側面側の先端とにそれぞれ回転軸１方向に向けて突出板６を突設し、各突出板６にバー３を設けることが好ましい。このような構成とすることで、撹拌羽根２ａ、２ｂの各先端により処理槽４の側面付近を撹拌できるとともに、撹拌羽根２ａ、２ｂの先端から突設した突出板６に設けたバー３により処理槽４の側面付近側に移動したバイオチップを持ち上げて処理槽４の側面に力を与えないようにでき、また、処理槽４の側面にバイオチップが付着しないようにできるものである。
【０００９】
また、駆動手段によって回転する撹拌羽根２を内蔵した生ごみ処理装置であって、回転軸１の一端側から中央位置に向けて片側の撹拌羽根２ａを右巻き螺旋状に設けるとともに、回転軸１の他端側から中央位置に向けてもう一方の撹拌羽根２ｂを左巻き螺旋状に設け、回転軸１と撹拌羽根２との間に回転軸１と撹拌羽根２とを連設する連結用羽根板６を設け、右巻螺旋状の攪拌羽根２ａと回転軸１とを連結する連結用羽根板６に回転軸１の軸方向と平行な方向の処理槽４の一方の側面付近を撹拌するためのバー３を上記処理槽４の一方の側面側に向けて突出して設け、左巻螺旋状の攪拌羽根２ｂと回転軸１とを連結する連結用羽根板６に回転軸１の軸方向と平行な方向の処理槽４の他方の側面付近を撹拌するためのバー３を上記処理槽４の他方の側面側に向けて突出して設けることも好ましい。このような構成とすることで、回転軸１を逆回転した場合に、右巻螺旋状の撹拌羽根２ａ、左巻螺旋状の撹拌羽根２ｂにより中央部から両側にバイオチップが移動するが、処理槽４の両側面付近側に移動したバイオチップを、撹拌羽根２ａ、２ｂの各先端により処理槽４の側面付近を撹拌できるとともに、撹拌羽根２ａ、２ｂの先端よりも回転軸１方向にずれた位置で連結用羽根板５から処理槽４の側面側に向けて突出したバー３により処理槽４の側面付近側に移動したバイオチップを持ち上げて処理槽４の側面に力を与えないようにでき、また、処理槽４の側面にバイオチップが付着しないようにできるものである。
【００１３】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１４】
生ごみを処理する処理槽４内には撹拌羽根２が内蔵してあり、この撹拌羽根２は回転軸１をモータのような駆動手段（図示せず）により回転することで処理槽４内において回転するようになっている。
【００１５】
撹拌羽根２は図１に示すように螺旋状をしており、処理槽４内に回転自在に架設した回転軸１が上記螺旋状をした撹拌羽根２の中心軸となっており、回転軸１と撹拌羽根２とは連結用羽根板５により連結してある。そして、本発明において撹拌羽根２は、回転軸１の一端側から中央位置に向けて右巻螺旋状をした片側の撹拌羽根２ａと、回転軸１の他端側から中央位置に向けて左巻螺旋状をした他の片側の撹拌羽根２ｂとの２つの分離された撹拌羽根２により構成してある。
【００１６】
本発明においては、上記のように右巻螺旋状の撹拌羽根２ａと左巻螺旋状の撹拌羽根２ｂを設けたものにおいて、例えば、図２のように回転軸１の軸方向と平行な方向の処理槽４の一方の側面に対向する右巻螺旋状の撹拌羽根２ａ部分に処理槽の一方の側面付近を撹拌するためのバーを１乃至複数個設け、回転軸１の軸方向と平行な方向の処理槽４の他方の側面に対向する左巻螺旋状の撹拌羽根２ｂ部分に処理槽４の他方の側面付近を撹拌するためのバー３を１乃至複数個設けてある。
【００１７】
図３に示す実施形態においては、右巻螺旋状の撹拌羽根２ａの先端から少し左巻螺旋状の撹拌羽根２ｂ側にずれた位置にバー３が設けてあり、左巻螺旋状の撹拌羽根２ｂの先端から少し右巻螺旋状の撹拌羽根側にずれた位置にバー３が設けた例が示してある。つまり、撹拌羽根２の処理槽４の側面と対向する面の回転軸１を中心にして螺旋状の撹拌羽根２の先端から角度αずれた位置にバー３が突設してある。
【００１８】
処理槽４内にはバイオチップと称する木質細片のような担体が充填してあり、処理槽４内に生ごみを投入し、バイオチップに生息している微生物の働きで生ごみを分解処理するものである。この場合、撹拌羽根２を回転して生ごみとバイオチップとを撹拌混合することで、生ごみをバイオチップ内に分散すると共にバイオチップに生息する微生物に酸素を供給して生ごみを効果的に分解するようになっている。
【００１９】
しかして、上記のように右巻螺旋状の撹拌羽根２ａと左巻螺旋状の撹拌羽根２ｂを設けることで、回転軸１を正回転すると右巻螺旋状の撹拌羽根２ａと左巻螺旋状の撹拌羽根２ｂの作用でバイオチップが処理槽４両側面から中央部に集まり、そこで、処理槽４内面に沿って上昇し、両側面に分散する働きにより空気を供給し且つ生ごみとバイオチップとの混合を行うのであるが、上記の作用中にバー３により中央部集まろうとするほとんどのバイオチップが持ち上げられ撹拌羽根２の最高点でそれが落ちて分散されることになり、効果的に混合され且つ効果的に空気が供給されるものである。また回転軸１を逆回転して右巻螺旋状の撹拌羽根２ａと左巻螺旋状の撹拌羽根２ｂの作用で中央部に集まったバイオチップを中央部から両側面方向に移動させる。
【００２０】
回転軸１を逆回転することで、上記のように右巻螺旋状の撹拌羽根２ａ、左巻螺旋状の撹拌羽根２ｂにより中央部から両側にバイオチップを移動した場合、螺旋状をした撹拌羽根２ａ、２ｂの各先端で処理槽４の側面付近の一部を撹拌するとともに、螺旋状をした撹拌羽根２ａ、２ｂの各先端から少し処理槽４の側面から離れる方向にずれた位置に設けたバー３により処理槽４の側面側に移動してきたバイオチップを持ち上げて処理槽４の側面に力を与えないようにして処理槽４の側面の破損を防止するとともに処理槽４の側面にバイオチップが付着するのを防止するようになっている。
【００２１】
図４には本発明の他の実施形態が示してある。本実施形態においては、右巻螺旋状の撹拌羽根２ａの先端の処理槽４の一側面と対向する面にバー３が設けてあり、左巻螺旋状の撹拌羽根２ｂの先端の処理槽４の他側面と対向する面にバー３が設けてある。各バー３はそれぞれ対向する処理槽４の側面側に向けて突出してある。そして、本実施形態においては、回転軸１を前述と同様にして正回転、逆回転して生ごみの処理を行うのであるが、逆回転した場合、処理槽４の両側面付近側に移動したバイオチップが両側面に最も近い撹拌羽根２ａ、２ｂの各先端においてバー３により効果的に持ち上げて処理槽４の側面に力を与えないようにし、また、処理槽４の側面にバイオチップが付着しないようにするものである
【００２２】
図５には本発明の更に他の実施形態が示してある。本実施形態においては、右巻螺旋状の撹拌羽根２ａの処理槽４の一側面と対向する部分と回転軸１とを連設する連結用羽根板５に処理槽４の一側面側に向けてバー３を突設してあり、また、左巻螺旋状の撹拌羽根２ｂの処理槽４の他側面と対向する部分と回転軸１とを連設する連結用羽根板５に処理槽４の他側面側に向けてバー３を突設してある。そして、本実施形態においては、回転軸１を前述と同様にして正回転、逆回転して生ごみの処理を行うのであるが、逆回転した場合、処理槽４の両側面付近側に移動したバイオチップが撹拌羽根２ａ、２ｂの各先端で処理槽４の側面付近の一部を撹拌するとともに、撹拌羽根２ａ、２ｂの各先端よりも回転軸１方向にずれた位置で連結用羽根板５に設けたバー３により処理槽４の側面付近側に移動したバイオチップを持ち上げて処理槽４の側面に力を与えないようにし、また、処理槽４の側面にバイオチップが付着しないようにするものである。
【００２３】
図６には本発明の更に他の実施形態が示してある。本実施形態においては、右巻螺旋状の撹拌羽根２ａの処理槽４の一側面側の先端と左側螺旋状の撹拌羽根２ｂの処理槽４の他側面側の先端とにそれぞれ回転軸１方向に向けて突出板６を突設し、各突出板６に処理槽４の側面側に向けてバー３が突設してある。本実施形態においては、回転軸１を前述と同様にして正回転、逆回転して生ごみの処理を行うのであるが、逆回転した場合、処理槽４の両側面付近側に移動したバイオチップが撹拌羽根２ａ、２ｂの各先端で処理槽４の側面付近の一部を撹拌するとともに、撹拌羽根２ａ、２ｂの各先端から突設した突出板６に設けたバー３により処理槽４の側面付近側に移動したバイオチップを持ち上げて処理槽４の側面に力を与えないようにし、また、処理槽４の側面にバイオチップが付着しないようにするものである。
【００２７】
なお、添付図面において４ａは処理槽４の回転軸１と平行な方向の側面を示している。
【００２８】
また、添付図面に示すように、連結用羽根板５に突起部５ａを形成しておくと撹拌効果がより向上するものである。

This garbage disposal apparatus is required to supply air and improve the mixing property between the biochip and the garbage in order to promote the decomposition action of microorganisms. For this reason, conventionally, a carrier such as a wood chip called biochip and garbage are agitated, and as this agitating means, a rotating blade 1 having a spiral agitating blade 2 is formed. It is known from Japanese Patent Laid-Open No. 8-84980. As shown in FIG. 7 , in the stirring blade shown in Japanese Patent Application Laid-Open No. 8-84980, the rotating shaft 1 rotatably installed in the processing tank 4 is the central axis of the spiral stirring blade 2. The rotating shaft 1 and the stirring blade 2 are connected by a connecting blade plate 5, and the stirring blade 2 is a right-handed spiral stirring from one end side of the rotating shaft 1 toward the center position. The blade 2a is composed of two separated stirring blades 2 which are a left-handed stirring blade 2b spirally turned from the other end side of the rotary shaft 1 toward the center position. When the rotating shaft 1 rotates, the stirring blade 2 gathers from the both side surfaces of the processing tank 4 to the central portion by the action of the right and left spiral windings, where it rises along the inner surface of the processing tank 4, Air is supplied by the action of dispersing on the surface, and garbage and biochip are mixed.
