Description

【0001】
【発明の属する技術分野】
本発明は、厨芥等の有機物を微生物の活動により分解処理する有機物処理装置に関する。
【0002】
【従来の技術】
一般家庭、飲食店の厨房内に発生する厨芥(生ごみ)等の有機物を処理するための一方法として、微生物による分解を利用する方法がある。この方法による有機物処理装置は、有機物を分解する微生物、及び該微生物の担体(木質細片、おが屑、活性炭等)を収納する処理槽の上部に投入口を設け、また内部に攪拌手段を配して構成され、前記投入口を経て処理槽内に投入される有機物を前記攪拌手段の動作により担体中に取り込み、この状態に放置して、前記担体中に生息する微生物の活動により分解処理する構成となっている。
【0003】
担体中に取り込まれた有機物の分解を良好に行わせるには、適量の水分を含み適温に保たれた担体中に適量の空気(酸素)を供給し、該担体の内部を微生物の活動に適した環境に保つことが重要であり、処理槽内部の換気手段と加熱手段とを備え、換気手段の動作により処理槽内に外気を供給すると共に、前記分解により生成される水分及びガスを処理槽外に排出して、担体内部の空気量及び水分量を適正に保つ一方、加熱手段の加熱動作により、処理槽の内部を適温に保ち、更に、前記攪拌手段の動作により担体を随時攪拌して、該担体の内部へ空気を取り込むと共に、分解により生成される水分及びガスを排出して、処理槽の内部環境を適正に維持する運転が行われている。
【0004】
さて、この種の有機物処理装置においては、以上の如く行われる運転の継続に伴い、分解処理後の残留物、有機物と共に投入される難分解物(ビニール袋、割箸、貝殻等)が処理槽内部の担体中に蓄積され、微生物の生息環境が徐々に悪化して、処理能力の低下を招くことから、処理槽内部の担体を適宜の周期にて取り出し、新たな担体に交換する必要がある。
【0005】
以上の如き担体の交換を容易に行わせるべく、従来から、特開平7-136627号公報(B09B 3/00)、特開平7-222967号公報(B09B 3/00)等に開示されているように、処理槽の一側(前側)下部に担体排出用の排出口をシャッタにより開閉自在に備え、担体交換に際しては、前記シャッタを取り外して排出口を開放することにより処理槽内部の担体を容易に取り出し得るようにした構成が採用されている。
【0006】
【発明が解決しようとする課題】
ところが、処理槽の底面に担体の排出口を開設した場合、該排出口の開口部周縁の強度が低下することが避けられず、処理槽内部の担体の重量、及び攪拌手段による担体の攪拌力の作用により前記周縁部が撓み変形し、前記シャッタによる閉止が良好に行えなくなるという問題があった。
【0007】
この問題は、排出口の周縁に、処理槽の外面側、又は内面側から補強リブを形成することにより緩和されるが、前記補強リブを外面に設ける場合、シャッタとの干渉を避けねばならず、また内面に設ける場合、攪拌手段の動作による担体の攪拌を阻害する虞れがある。
【0008】
これらのことから従来においては、処理槽全体の肉厚を大きくし、また、排出口の周縁を他部よりも厚肉とすることにより対応しているが、前記処理槽は大嵩の中空容器であり、成型のための金型形状が複雑化し、また全体重量の増加を招来するという不都合があった。
【0009】
本発明は斯かる事情に鑑みてなされたものであり、処理槽の底部に開設された担体の排出口の周縁部を、処理槽の側での処置によらずに強化することができ、担体の重量及び攪拌に伴う作用力による撓みを有効に防止して、シャッタによる閉止状態を長期間に亘って良好に維持し得る有機物処理装置を提供することを目的とする。
【0010】
【課題を解決するための手段】
本発明に係る有機物処理装置は、有機物を分解する微生物、及び該微生物の担体を収納する処理槽の下部に前記担体の排出口をシャッタにより開閉自在に設け、運転に伴って劣化した担体を、前記シャッタの取り外しにより開放された前記排出口を経て外部に取り出すようにした有機物処理装置において、前記外装ケースは、前記処理槽の下部を支えるロアケースと、該ロアケースの上部に被せてあり、その下縁をロアケースの周縁に固定して一体化されたアッパケースとを備え、前記排出口の周縁部を、前記シャッタを介して前記ロアケースに支える構成としてあることを特徴とする。
【0011】
本発明においては、排出口を開閉するシャッタが、該排出口と処理槽の下部を支持するロアケースとの間に介在し、排出口の周縁部を高強度のロアケースに支える作用をなし、処理槽内部の担体の重量、及び該担体の攪拌に伴う作用力により生じる前記周縁部の撓みを、シャッタ及びロアケースの剛性により抑える。
【0012】
更に加えて、前記シャッタを前記排出口の周縁部を支える位置に拘束する手段を備えることを特徴とする。
【0013】
本発明においては、例えば、シャッタの外側に装着される外装カバーの作用により該シャッタの移動を拘束して、排出口の周縁部をロアケースに支えた状態を確実に保つ。
【0014】
【発明の実施の形態】
以下本発明をその実施の形態を示す図面に基づいて詳述する。図1は、本発明に係る有機物処理装置の正面断面図、図2は、同じく側断面図である。
【0015】
図において1は、有機物を分解処理する処理槽である。該処理槽1は、図2に示す如く、下半部を半円形とした側断面形状を有し、上部の略全面に有機物投入のための開口を備える中空容器であり、矩形箱形をなす外装ケース2に内包されている。
【0016】
外装ケース2は、その上部に処理槽1を支持すると共に、幅方向の両側に支持脚を一体形成してなる高強度のロアケース2aと、該ロアケース2aの上部に被せてあり、その下縁をロアケース2aの周縁に固定して一体化されたアッパケース2bとを備えて構成されており、処理槽1の上部開口には、図2に示す如く、アッパケース2bの天板から垂下された投入シュート20が差し込まれて、有機物の投入口が形成されており、投入シュート20の上部は、アッパケース2b上面に取付けた上蓋21により開閉自在に覆ってある。
【0017】
図3は、上蓋21、アッパケース2bの天板、及び後述するカバー板31取り除いた状態を上方から見た平面図である。これらに示す如く処理槽1の上部には、適宜の幅を内側に折り返し、矩形に開口する投入口の周囲を縁取る折り返し部10が形成されており、該折り返し部10には、これを内外に貫通する複数の吸気孔11,11…が形成されている。
【0018】
幅方向一側の折り返し部10には、図1に示す如く、アッパケース2bとの間の隙間を塞ぐ態様に支持板30が取り付けてあり、該支持板30の前半部には、運転制御のための電子部品が実装された制御基板3が、その上部をカバー板31により覆って支持され、同じく後半部には、図3に示す如く、処理槽1内部の換気のための換気ファン32が取り付けられている。
【0019】
図4は、図3のIV−IV線による断面図、図5は、同じくV−V線による断面図である。制御基板3の上部を覆うカバー板31は、図4に示す如く、後側において換気ファン32の上部に至るまで、また図5に示す如く、側部において投入シュート20の背面近傍に達する位置まで夫々延設されており、支持板30上の制御基板3の取り付け位置は、図4に示す如く、その後側において支持板30の表面から上向きに立設されたリブ板33により換気ファン32の装着位置と隔絶され、また、側部においてカバー板31の内面から下方に延びるリブ板34により、投入シュート20の背面側と隔絶されている。
【0020】
これにより、投入シュート20の背面には、該投入シュート20と、カバー板31、リブ板34及び支持板30とにより四方を囲まれ、制御基板3の後側を迂回して換気ファン32の取り付け位置に連通する排気風路35が形成されたこととなり、該排気風路35は、同側の投入シュート20の側面を貫通し、排気フィルタが装着された排気孔22を介して処理槽1の内部に連通させてある。また、排気風路35の後側は、換気ファン32の下側に連設された排気ダクト36により、アッパケース2bの背面に開口する排気口37に連続させてある。
【0021】
以上の構成により、換気ファン32が駆動された場合、処理槽1の内部の空気は、排気孔22を経て排気風路35内に導入され、制御基板3の取り付け位置を迂回して換気ファン32に吸い込まれて、排気ダクト36及び排気口37を経て外気に排出される。この排気は、処理槽1の内部に後述する如く発生する水分を含んでおり、この水分は、換気ファン32の取り付け板上に水滴となって付着する。図3に示す如く、換気ファン32の取り付け板の周囲には、これを上下に貫通する複数の水抜き孔38,38…が開設してあり、取り付け板上に溜まる水分を下部に逃がす構成としてある。
【0022】
図4に示す如く、制御基板3の取り付け位置の後側のリブ板33は、上部を覆うカバー板31との間にわずかな隙間を有しており、また制御基板3の取り付け位置の前部は、適宜の隙間を介してアッパケース2bの内側に連通させてあり、換気ファン32が駆動された場合、処理槽1内部からの前述した排気と共に、制御基板3の取り付け室内にアッパケース2b内側の空気が直接的に吸い込まれ、リブ板33上部の隙間を経て排気風路35に至る通気が生じ、制御基板3に実装された電子部品は、この通気との接触により冷却されるようになしてある。
【0023】
このように生じる冷却用の通気は、排気風路35内を流れる排気とは異なり、殆ど水分を含まないことから、制御基板3上の電子部品の誤動作を引き起こす虞れはない。また、前記通気の出口となる前記リブ板33上縁の隙間はわずかであり、更に、これの外側の排気風路35の内部は風上となることから、排気風路35内を流れる前記排気の主流が制御基板3の取り付け室内に侵入する虞れはない。
【0024】
以上の如く構成された排気風路35は、実質的に、制御基板3の支持板30上に、該支持板30と上カバー板31との2部品により簡素に構成されており、処理槽1の内部からの排気と同時に、制御基板3の冷却も可能としたものとなっており、組み立てが容易であると共に、制御基板3と換気ファン32との間の配線を短くでき、配線作業が容易となり、また電磁ノイズの発生を抑えることができる。
【0025】
また、前記排気風路35への入口となる排気孔22は、処理槽1の最上部に位置する投入シュート20の側面に形成されており、処理槽1の内部に後述の如く発生する軽量の水蒸気を効果的に排出することができる。
【0026】
図4に示す如く、制御基板3の上部を覆うカバー板31には運転表示のための表示LED39が取り付けてある。図6は、この取り付け部分近傍の拡大図であり、本図に示す如く、カバー板31の前部上面には、前記表示LED39に対応する小径の貫通孔 31aが形成され、この形成部位の外面には、前記貫通孔 31aの外周を巡る円周状の係合溝 31bが形成されており、該係合溝 31bの内側にてカバー板31の内面に突設された筒状部内には、周方向の複数か所にて前記貫通孔 31aの形成位置にまで張り出すガイドリブ 31c,31c…が形成されている。
【0027】
前記表示LED39は、カバー板31の内面側から前記ガイドリブ 31c,31c…間にその先端を嵌入し、これらに沿って前記貫通孔 31aの内側に面する位置にまで押し込むことにより、図示の如くカバー板31に保持されており、この状態で行われる前記支持板30へのカバー板31の取り付けにより、制御基板3の上部に図示の如く位置決め固定される。
【0028】
一方、前記カバー板31の上部を覆うアッパケース2bの天板には、カバー板31における前記貫通孔 31aの形成位置に対応するように、内外に貫通する円形の見通し孔 20aが形成されており、この形成部位の内面には、前記見通し孔 20aの外周を巡る円筒状をなして係合突起 20bが突設されている。この係合突起 20bは、カバー板31の外面に形成された係合溝 31bと対応するサイズを有し、アッパケース2bの取り付けに際し、前記係合溝 31bに上部から係合せしめられており、カバー板31の貫通孔 31aの外側に前記見通し孔 20aが整合するように位置決めする作用をなす。これにより、貫通孔 31aに押し込み固定された表示LED39は、前記見通し孔 20aを経てアッパケース2bの天板から視認することが可能である。
【0029】
このように、制御基板3への接続が必要な電装部品であり、外装ケース2の外側からの視認が必要な表示LED39がカバー板31に取り付けてあり、この取り付けが、カバー板31の組み付け時に制御基板3との間の配線処理を含めて容易に実施でき、大嵩の部品である前記アッパケース2bの組み付けに際し、前述した配線処理が不要となることから、組み付け工数の削減が図れる。
【0030】
以上の如き取り付けは、運転表示のための表示LED39に限らず、運転スイッチ等、制御基板3との接続が必要であると共に、外装ケース2の外側に露出させることが必要な他の電装部品に対しても実施することができ、これにより組み付け工数の更なる削減が可能となる。なお前記見通し孔 20aは、アッパケース2bの天板に被着された透明樹脂製のシート 20cにより上部から覆われており、雨水、塵芥等の異物の侵入を防ぐようにしてある。
【0031】
処理槽1の内部は、前述の如く、折り返し部10に形成された前記吸気孔11,11…によりアッパケース2bの内側に連通しており、前記換気ファン32の駆動により前述した排気が生じた場合、処理槽1の内部には、前記吸気孔11,11…を経てアッパケース2b内の空気が吸込まれる。
【0032】
図7は、図3よりもやや下位置での横断面図であり、本図と図1及び図2とに示す如く、アッパケース2b内面には、その高さ方向の略中央において、処理槽1の周囲から一体的に張り出された当て板12が当接せしめられ、外面からの押圧による変形を防ぐ構成となっており、アッパケース2bの内部は、前記当て板12により上下に仕切られている。
【0033】
該当て板12は、制御基板3の支持板30の取り付け部の下位置において、アッパケース2bとの間の隙間を埋めるべく他部よりも幅広となっており、この幅広部分には、円孔状をなす複数の通気孔13,13…が貫通形成され、アッパケース2bの上下部間での通気がこれらの通気孔13,13…に集中して生じるようになしてある。また前記当て板12の幅広部分には、上方に対向する前記制御基板3の支持板30に向けて円錐形をなす支持脚14が立設してあり、この支持脚14の先端は、図4に示す如く、前記支持板30にねじ止め固定されており、処理槽1の折り返し部10にその一縁を片持ち支持された前記支持板30をその下側から支えている。
【0034】
前述の如く、制御基板3を支持する前記支持板30の上部は、前記カバー板31を介してアッパケース2bの天板に近接しており、使用中にアッパケース2bの天板に下向きの外力が加えられたとき、この作用力は、下方への押し下げ力として支持板30に作用することになる。前記支持脚14は、支持板30を下方の前記当て板12に連結し、前述した如く作用する押し下げ力を当て板12に伝えて、支持板30の支持剛性を確保する作用をなすものである。
【0035】
アッパケース2bの下半部は、これの下部に一体化されたロアケース2aの底面に形成された図示しない吸気孔により外部に連通させてあり、前記換気ファン32が駆動された場合、図1中に矢符により示す如く、ロアケース2aの底面から外気が吸い込まれ、前記当て板12に形成された複数の通気孔13,13…を通ってアッパケース2bの上半部に通気し、更に、前記吸気孔11,11…を経て処理槽1の内部に導入されるようになっている。
【0036】
ロアケース2a上に支持された処理槽1の内側下部には、両側壁間に横架された攪拌軸40に軸長方向に所定の間隔毎に複数の攪拌棒41,41…を放射状に突設してなる攪拌体4が配してある。図1に示す如く、処理槽1の一側下部には攪拌モータMが配してあり、この攪拌モータMの出力端は、同側への前記攪拌軸40の突出端に減速機構42を介して連結され、前記攪拌体4は、前記減速機構42を介して攪拌軸40に伝達される攪拌モータMの回転力により回転駆動されるようになしてある。
【0037】
処理槽1の内部には、おが屑、木質細片等を用いてなる微生物の担体Aが、図2中に実線にて示す如く、前記攪拌体4の攪拌棒41,41…の先端が、その回転域の上半部にて前記担体Aの表面から適長突出する深さ(標準レベル)を有して収納されている。処理槽1の底部の半円形状は、図2に示す如く、前記攪拌棒41,41…の回転軌跡の下半部に沿うように設定してあり、処理槽1内に収納された担体Aは、攪拌体4の回転により処理槽1の幅方向及び深さ方向の全域に亘って攪拌されるようになっている。
【0038】
このような担体Aの攪拌は、上部の投入口から処理槽1内へ有機物が投入されたとき、この有機物を担体A中に取り込むべく実施され、また、この後の運転中においては、有機物の分解により担体A中に生成される水分及びガスを処理槽1の上部空間に排出する一方、処理槽1の内部への吸気を担体A中に取り込み、該担体Aの内部環境を適正に維持すべく、後述する手順にて随時実施される。
【0039】
攪拌モータMと減速機構42とは、図1に示す如く、前記当て板12の幅広部分の下において、処理槽1とアッパケース2bとの間に確保されたスペースを利用し、前述した如き吸気の経路の中途に配してあり、前記吸気により攪拌モータMが有効に冷却されるようにしてある。
【0040】
以上の如く構成された処理槽1の半円形断面をなす底面の一側(前側)には、内部に収納された担体Aの排出口17が、図2に示す如く、引出し式のシャッタ5により開閉自在に覆って開設してあり、この排出口17を下側から臨むロアケース2aの底部には、前方に向けて傾斜する排出シュート23が一体形成され、該排出シュート23の前部には、外装カバー6により開閉自在に担体Aの取り出し口25が形成されている。また、処理槽1の底部外面には、図2に示す如く、内部加熱のためのシート状をなすヒータHが、前部に開設された排出口17の形成域を避け、後側外面を主体として被着してある。
【0041】
以上の如く構成された有機物処理装置は、厨芥等の有機物を、上蓋21を開放して処理槽1内に投入して使用される。処理槽1内に投入された有機物は、攪拌モータMにより駆動される攪拌体4の正逆回転により担体A中に取り込まれ、該担体A中に生息する微生物の活動により分解処理される。この間、制御基板3上に構成された運転制御部の動作により、ヒータHの通電制御、前記換気ファン32の駆動制御、及び攪拌モータMの駆動制御が行われる。
【0042】
パネルヒータHへの通電制御は、処理槽1の内部温度を適温に保つべく、特に寒冷期に行われ、また換気ファンの駆動制御は、処理槽1の内部に適量の空気を送り込むと共に、前記分解により生成される水分及びガスを排出すべく常時行われ、更に、攪拌モータMの駆動制御は、処理槽1内部の担体Aを定期的に攪拌して、担体A中に空気を取り込むと共に、担体A中に生成される水分及びガスを放出すべく間欠的に行われる。このような制御動作により処理槽1の内部は、担体A中に生息する微生物の活動に適した環境に保たれ、該担体A中に取り込まれた有機物は、堆肥化した少量の残留物を残し、炭酸ガスを主成分とするガスと水とに分解される。
【0043】
一方、以上の如き運転の継続に伴って処理槽1内部の担体A中には、分解処理後の残留物、有機物と共に投入される難分解物(ビニール袋、割箸、貝殻等)が蓄積され、該担体A中における微生物の生息環境が悪化し、処理能力の低下を招くことから、劣化した担体Aの交換が必要となる。
【0044】
この交換に際しては、まず、処理槽1内部の劣化した担体Aの取り出しが行われる。この取り出しは、前記外装カバー6を取り外し、ロアケース2a前面の取り出し口25を開放した後、前記シャッタ5を取り外し、処理槽1の下部前面の排出口17を開放して、処理槽1内部の担体Aを前記排出口17を経て排出シュート23上に落とし、該排出シュート23の傾斜に沿って前方に掻き出して行われる。
【0045】
このようにして担体A取り出しを終えた後、まず、シャッタ5を装着して排出口17を閉止し、次いで外装カバー6を装着して取り出し口25を閉止して、処理槽1内にその上部から新たな担体Aを投入する。このように交換を終えた後は、前述した運転の再開により有機物処理が可能となる。
【0046】
以上の如き担体Aの交換に際し、劣化した担体Aの取り出しのために処理槽1の底部に形成された排出口17は、前記取り出しを容易に行わせるべく、可及的に大なる開口面積を有して形成されている。図8は、ロアケース2aの前面に開設された取り出し口25を前方から見た斜視図である。(a)には、外装カバー6及びシャッタ5を取り外した状態が、(b)には、シャッタ5のみを取り付けた状態が夫々示されており、前記排出口17は、図8(a)に示す如く、取り出し口25から見通し得る処理槽1の底部に、これの略全幅に亘る矩形の開口として形成されている。
【0047】
このように開設された排出口17には、図8(b)に示す如くシャッタ5を閉止して行われる前述した運転中には、処理槽1内部の担体Aの重量と、前記攪拌体4による担体Aの攪拌に伴う作用力とが加わり、その周縁部、特に、長寸である下縁と上縁とに撓み変形が生じる。本発明においては、シャッタ5を利用して前記撓み変形を防ぐ構成としてある。
【0048】

BACKGROUND OF THE INVENTION
The present invention relates to an organic matter processing apparatus that decomposes organic matter such as soot by the activity of microorganisms.
[0002]
[Prior art]
As a method for treating organic matter such as rice cake (garbage) generated in kitchens of general households and restaurants, there is a method using decomposition by microorganisms. An organic matter processing apparatus according to this method is provided with an inlet at the top of a treatment tank that contains microorganisms that decompose organic matter and carriers of the microorganisms (wood fine pieces, sawdust, activated carbon, etc.), and an agitation means is provided inside. The organic substance introduced into the treatment tank through the inlet is taken into the carrier by the operation of the stirring means, and is left in this state and decomposed by the activity of microorganisms that live in the carrier. It has become.
[0003]
In order to successfully decompose organic substances incorporated in the carrier, an appropriate amount of air (oxygen) is supplied to the carrier that contains an appropriate amount of moisture and kept at an appropriate temperature, and the inside of the carrier is suitable for the activity of microorganisms. It is important to maintain a clean environment, and it is provided with a ventilation means and a heating means inside the treatment tank, and supplies the outside air into the treatment tank by the operation of the ventilation means, and the moisture and gas generated by the decomposition are treated in the treatment tank. It is discharged to the outside, and the amount of air and moisture inside the carrier is kept appropriate, while the heating operation of the heating means keeps the inside of the treatment tank at an appropriate temperature, and the carrier is stirred as needed by the operation of the stirring means. In addition, air is taken into the carrier and moisture and gas generated by the decomposition are discharged to maintain the internal environment of the treatment tank appropriately.
[0004]
Now, in this kind of organic matter processing equipment, as the operation is continued as described above, the residue after decomposition treatment and the hard-to-decompose matter (plastic bags, disposable chopsticks, shells, etc.) put together with the organic matter are inside the treatment tank. Therefore, it is necessary to take out the carrier in the treatment tank at an appropriate cycle and replace it with a new carrier.
[0005]
In order to facilitate the exchange of the carrier as described above, it has been conventionally disclosed in Japanese Patent Application Laid-Open No. 7-13627 (B09B 3/00), Japanese Patent Application Laid-Open No. 7-222967 (B09B 3/00) and the like. In addition, a discharge port for discharging the carrier is provided at the lower part of one side (front side) of the processing tank so that it can be opened and closed by a shutter. When replacing the carrier, the carrier inside the processing tank can be easily removed by removing the shutter and opening the discharge port. A configuration that can be taken out is adopted.
[0006]
[Problems to be solved by the invention]
However, when a carrier discharge port is opened at the bottom of the treatment tank, it is inevitable that the strength of the periphery of the opening of the discharge port is reduced, and the weight of the carrier inside the treatment tank and the stirring force of the carrier by the stirring means As a result, the peripheral edge is bent and deformed, and the shutter cannot be closed satisfactorily.
[0007]
This problem can be alleviated by forming reinforcing ribs on the outer periphery side or inner surface side of the treatment tank at the periphery of the discharge port. However, when the reinforcing ribs are provided on the outer surface, interference with the shutter must be avoided. Further, when it is provided on the inner surface, there is a possibility that the stirring of the carrier due to the operation of the stirring means may be hindered.
[0008]
In view of the above, in the prior art, the overall thickness of the processing tank is increased and the peripheral edge of the discharge port is made thicker than the other parts. Thus, there are inconveniences that the mold shape for molding becomes complicated and the total weight increases.
[0009]
The present invention has been made in view of such circumstances, and it is possible to reinforce the peripheral portion of the discharge port of the carrier opened at the bottom of the treatment tank without depending on the treatment on the treatment tank side. It is an object of the present invention to provide an organic substance processing apparatus that can effectively prevent bending due to the weight and the action force accompanying stirring and can maintain a closed state by a shutter well over a long period of time.
[0010]
[Means for Solving the Problems]
The organic matter processing apparatus according to the present invention is provided with a microorganism that decomposes organic matter, and a carrier that has been deteriorated during operation by providing a discharge port of the carrier at a lower portion of a treatment tank that contains the carrier of the microorganism so as to be opened and closed by a shutter. In the organic matter processing apparatus which is taken out through the discharge port opened by removing the shutter, the outer case covers the lower case supporting the lower part of the processing tank and the upper part of the lower case, And an upper case integrated with an edge fixed to the periphery of the lower case, and the periphery of the discharge port is supported by the lower case via the shutter.
[0011]
In the present invention, a shutter that opens and closes the discharge port is interposed between the discharge port and a lower case that supports the lower portion of the treatment tank, and has a function of supporting the peripheral edge of the discharge port on the high-strength lower case. The deflection of the peripheral edge caused by the weight of the internal carrier and the acting force accompanying the stirring of the carrier is suppressed by the rigidity of the shutter and the lower case.
[0012]
In addition, it is characterized by comprising means for restraining the shutter to a position supporting the peripheral edge of the discharge port.
[0013]
In the present invention, for example, the movement of the shutter is restrained by the action of an exterior cover mounted on the outside of the shutter, and the state where the peripheral edge of the discharge port is supported by the lower case is reliably maintained.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof. FIG. 1 is a front sectional view of an organic matter processing apparatus according to the present invention, and FIG. 2 is a side sectional view.
[0015]
In the figure, reference numeral 1 denotes a treatment tank for decomposing organic substances. As shown in FIG. 2, the treatment tank 1 is a hollow container having a side cross-sectional shape with a semicircular lower half, and an opening for introducing an organic substance on substantially the entire upper surface, and has a rectangular box shape. It is enclosed in the outer case 2.
[0016]
The outer case 2 supports the processing tank 1 on the upper part thereof, and covers a high-strength lower case 2a formed by integrally forming support legs on both sides in the width direction, and an upper part of the lower case 2a. The upper case 2b is fixed to and integrated with the periphery of the lower case 2a. The upper opening of the processing tank 1 is dropped from the top plate of the upper case 2b as shown in FIG. The chute 20 is inserted to form an organic material inlet, and the upper part of the input chute 20 is covered with an upper lid 21 attached to the upper surface of the upper case 2b so as to be freely opened and closed.
[0017]
FIG. 3 is a plan view of the state in which the upper lid 21, the top plate of the upper case 2b, and a cover plate 31 described later are removed as viewed from above. As shown in these figures, an upper portion of the treatment tank 1 is formed with a folded portion 10 that is folded back to an appropriate width and borders the periphery of the inlet that opens in a rectangular shape. A plurality of intake holes 11, 11.
[0018]
As shown in FIG. 1, a support plate 30 is attached to the folded portion 10 on one side in the width direction so as to close the gap between the upper case 2 b, and the front half of the support plate 30 has operation control. The control board 3 on which electronic components for mounting are mounted is supported by covering the upper part with a cover plate 31, and a ventilation fan 32 for ventilating the inside of the processing tank 1 is provided in the second half as shown in FIG. It is attached.
[0019]
4 is a cross-sectional view taken along the line IV-IV of FIG. 3, and FIG. 5 is a cross-sectional view taken along the line V-V. The cover plate 31 covering the upper part of the control board 3 reaches the upper part of the ventilation fan 32 on the rear side as shown in FIG. 4 and reaches the position near the back of the closing chute 20 on the side part as shown in FIG. As shown in FIG. 4, the mounting position of the control board 3 on the support plate 30 is extended by a rib plate 33 erected upward from the surface of the support plate 30 on the rear side, as shown in FIG. The ribs 34 are separated from the positions and separated from the back side of the charging chute 20 by rib plates 34 extending downward from the inner surface of the cover plate 31 at the side portions.
[0020]
As a result, the back surface of the charging chute 20 is surrounded on all sides by the charging chute 20, the cover plate 31, the rib plate 34, and the support plate 30, and the ventilation fan 32 is mounted around the rear side of the control board 3. An exhaust air passage 35 communicating with the position is formed, and the exhaust air passage 35 penetrates the side surface of the input chute 20 on the same side and passes through the exhaust hole 22 in which an exhaust filter is attached. It communicates with the inside. In addition, the rear side of the exhaust air passage 35 is connected to an exhaust port 37 opened on the back surface of the upper case 2b by an exhaust duct 36 connected to the lower side of the ventilation fan 32.
[0021]
With the above configuration, when the ventilation fan 32 is driven, the air inside the processing tank 1 is introduced into the exhaust air passage 35 through the exhaust hole 22, bypassing the mounting position of the control board 3, and the ventilation fan 32. And is discharged to the outside air through the exhaust duct 36 and the exhaust port 37. This exhaust gas contains water generated in the processing tank 1 as described later, and this water adheres as water droplets on the mounting plate of the ventilation fan 32. As shown in FIG. 3, a plurality of drain holes 38, 38... Are formed around the attachment plate of the ventilation fan 32 so as to allow moisture accumulated on the attachment plate to escape downward. is there.
[0022]
As shown in FIG. 4, the rib plate 33 on the rear side of the mounting position of the control board 3 has a slight gap with the cover plate 31 covering the upper part, and the front part of the mounting position of the control board 3. Is communicated with the inside of the upper case 2b through an appropriate gap. When the ventilation fan 32 is driven, the inside of the upper case 2b is placed in the mounting chamber of the control board 3 together with the exhaust gas from the inside of the processing tank 1. The air is directly sucked in, and the ventilation to the exhaust air passage 35 occurs through the gap above the rib plate 33, and the electronic components mounted on the control board 3 are cooled by the contact with the ventilation. It is.
[0023]
Unlike the exhaust gas flowing through the exhaust air passage 35, the cooling air flow generated in this way hardly contains moisture, so there is no possibility of causing malfunction of the electronic components on the control board 3. Further, the clearance between the upper edge of the rib plate 33 serving as the outlet of the ventilation is slight, and further, the inside of the exhaust air passage 35 outside this is windward, so that the exhaust flowing in the exhaust air passage 35 is There is no possibility that the mainstream will enter the mounting chamber of the control board 3.
[0024]
The exhaust air passage 35 configured as described above is substantially simply formed on the support plate 30 of the control board 3 by the two parts of the support plate 30 and the upper cover plate 31. The control board 3 can be cooled at the same time as exhausting from the inside of the fan, so that the assembly is easy and the wiring between the control board 3 and the ventilation fan 32 can be shortened and the wiring work is easy. In addition, the generation of electromagnetic noise can be suppressed.
[0025]
An exhaust hole 22 serving as an inlet to the exhaust air passage 35 is formed on the side surface of the charging chute 20 positioned at the uppermost portion of the processing tank 1 and is a lightweight that is generated in the processing tank 1 as described later. Water vapor can be effectively discharged.
[0026]
As shown in FIG. 4, a display LED 39 for displaying an operation is attached to a cover plate 31 that covers the upper portion of the control board 3. FIG. 6 is an enlarged view of the vicinity of the attachment portion. As shown in the figure, a small-diameter through hole 31a corresponding to the display LED 39 is formed on the upper surface of the front portion of the cover plate 31, and the outer surface of this formation portion. Is formed with a circumferential engagement groove 31b that goes around the outer periphery of the through hole 31a, and inside the engagement groove 31b, in the cylindrical portion protruding from the inner surface of the cover plate 31, Guide ribs 31c, 31c... Projecting to the formation position of the through hole 31a are formed at a plurality of locations in the circumferential direction.
[0027]
The indicator LED 39 is inserted into the guide ribs 31c, 31c,... From the inner surface side of the cover plate 31 and pushed into the position facing the inside of the through hole 31a along the guide ribs 31c, 31c. By holding the cover plate 31 to the support plate 30 performed in this state, it is positioned and fixed on the upper portion of the control board 3 as shown in the figure.
[0028]
On the other hand, the top plate of the upper case 2b covering the upper part of the cover plate 31 is formed with a circular line-of-sight hole 20a penetrating inward and outward so as to correspond to the formation position of the through hole 31a in the cover plate 31. On the inner surface of this formation site, an engaging projection 20b is formed so as to project in a cylindrical shape around the outer periphery of the line-of-sight hole 20a. The engagement protrusion 20b has a size corresponding to the engagement groove 31b formed on the outer surface of the cover plate 31, and is engaged with the engagement groove 31b from above when the upper case 2b is attached. The cover plate 31 is positioned so that the line-of-sight hole 20a is aligned with the outside of the through hole 31a. Thereby, the display LED 39 pushed and fixed in the through hole 31a can be visually recognized from the top plate of the upper case 2b through the line-of-sight hole 20a.
[0029]
In this way, the display LED 39 that is an electrical component that needs to be connected to the control board 3 and that needs to be viewed from the outside of the exterior case 2 is attached to the cover plate 31, and this attachment is performed when the cover plate 31 is assembled. The wiring process with the control board 3 can be easily implemented, and the above-described wiring process is not required when the upper case 2b, which is a bulky part, is assembled, so that the number of assembling steps can be reduced.
[0030]
The mounting as described above is not limited to the display LED 39 for operation display, but is connected to the control board 3 such as an operation switch, and to other electrical components that need to be exposed to the outside of the outer case 2. This can also be implemented, and this makes it possible to further reduce the assembly man-hours. The line-of-sight hole 20a is covered from above by a transparent resin sheet 20c attached to the top plate of the upper case 2b so as to prevent intrusion of foreign matters such as rainwater and dust.
[0031]
As described above, the inside of the processing tank 1 communicates with the inside of the upper case 2b through the intake holes 11, 11... Formed in the folded portion 10, and the exhaust described above is generated by the driving of the ventilation fan 32. In this case, the air in the upper case 2b is sucked into the processing tank 1 through the intake holes 11, 11,.
[0032]
FIG. 7 is a cross-sectional view at a position slightly below that of FIG. 3. As shown in FIG. 1 and FIGS. 1 and 2, the inner surface of the upper case 2b has a treatment tank at the approximate center in the height direction. 1 is a structure in which a contact plate 12 projecting integrally from the periphery of 1 is brought into contact with each other and is prevented from being deformed by pressing from the outer surface, and the interior of the upper case 2b is partitioned vertically by the contact plate 12. ing.
[0033]
Correspondingly, the plate 12 is wider than the other portion at a position below the mounting portion of the support plate 30 of the control board 3 so as to fill a gap with the upper case 2b. A plurality of ventilation holes 13, 13... Are formed so as to penetrate, and ventilation between the upper and lower portions of the upper case 2b is concentrated on these ventilation holes 13, 13. A support leg 14 having a conical shape is erected on the wide portion of the contact plate 12 toward the support plate 30 of the control board 3 facing upward. As shown in FIG. 2, the support plate 30 is fixed to the support plate 30 by screws, and the support plate 30 is supported by the folded portion 10 of the treatment tank 1 at one end thereof.
[0034]
As described above, the upper portion of the support plate 30 that supports the control board 3 is close to the top plate of the upper case 2b through the cover plate 31, and the downward external force is applied to the top plate of the upper case 2b during use. When is applied, this acting force acts on the support plate 30 as a downward pushing force. The support leg 14 connects the support plate 30 to the lower contact plate 12 and transmits the pressing force acting as described above to the contact plate 12, thereby ensuring the support rigidity of the support plate 30. .
[0035]
The lower half of the upper case 2b communicates with the outside through an intake hole (not shown) formed in the bottom surface of the lower case 2a integrated with the lower portion of the upper case 2b. As shown by the arrows in FIG. 4, outside air is sucked from the bottom surface of the lower case 2a, passes through a plurality of vent holes 13, 13 ... formed in the pad plate 12, and passes through the upper half of the upper case 2b. It is introduced into the inside of the processing tank 1 through the intake holes 11, 11,.
[0036]
A plurality of stirring rods 41, 41... Project radially at predetermined intervals in the axial direction on the stirring shaft 40 laid horizontally between both side walls at the lower inner side of the treatment tank 1 supported on the lower case 2 a. A stirring body 4 is arranged. As shown in FIG. 1, a stirring motor M is arranged at one side lower part of the processing tank 1, and an output end of the stirring motor M is connected to a protruding end of the stirring shaft 40 to the same side via a speed reduction mechanism 42. The stirring body 4 is rotationally driven by the rotational force of the stirring motor M transmitted to the stirring shaft 40 via the speed reduction mechanism 42.
[0037]
Inside the treatment tank 1, a carrier A for microorganisms using sawdust, wood strips, etc., as indicated by solid lines in FIG. 2, the tips of the stirring rods 41, 41. The upper half of the rotation region is stored with a depth (standard level) protruding from the surface of the carrier A by an appropriate length. The semicircular shape of the bottom of the processing tank 1 is set along the lower half of the rotation trajectory of the stirring rods 41, 41, as shown in FIG. 2, and the carrier A stored in the processing tank 1 is used. Is stirred over the entire region in the width direction and depth direction of the treatment tank 1 by the rotation of the stirring body 4.
[0038]
Such agitation of the carrier A is performed so that the organic substance is taken into the carrier A when the organic substance is introduced into the treatment tank 1 from the upper inlet, and during the subsequent operation, Moisture and gas generated in the carrier A due to the decomposition are discharged into the upper space of the treatment tank 1, while intake air to the inside of the treatment tank 1 is taken into the carrier A, and the internal environment of the carrier A is properly maintained. Therefore, it is carried out at any time according to the procedure described later.
[0039]
As shown in FIG. 1, the agitation motor M and the speed reduction mechanism 42 use the space secured between the processing tank 1 and the upper case 2b under the wide portion of the abutting plate 12, and intake air as described above. The stirring motor M is effectively cooled by the intake air.
[0040]
On one side (front side) of the bottom surface of the processing tank 1 having the semicircular cross section configured as described above, a discharge port 17 for the carrier A housed therein is provided by a drawer-type shutter 5 as shown in FIG. Opened so as to be openable and closable, the bottom of the lower case 2a facing the discharge port 17 from the lower side is integrally formed with a discharge chute 23 that inclines forward, and at the front of the discharge chute 23, An outlet 25 for the carrier A is formed by the outer cover 6 so as to be opened and closed. Further, on the outer surface of the bottom of the processing tank 1, as shown in FIG. 2, a heater H that forms a sheet for internal heating avoids the formation area of the discharge port 17 opened at the front, and mainly forms the rear outer surface. It is attached as.
[0041]
The organic matter processing apparatus configured as described above is used by putting organic matter such as soot into the treatment tank 1 with the upper lid 21 opened. The organic matter thrown into the treatment tank 1 is taken into the carrier A by the forward and reverse rotation of the stirring member 4 driven by the stirring motor M, and is decomposed by the activity of microorganisms living in the carrier A. During this time, the energization control of the heater H, the drive control of the ventilation fan 32, and the drive control of the stirring motor M are performed by the operation of the operation control unit configured on the control board 3.
[0042]
The energization control to the panel heater H is performed particularly in the cold season in order to keep the internal temperature of the processing tank 1 at an appropriate temperature, and the drive control of the ventilation fan sends an appropriate amount of air into the processing tank 1 and It is always performed to discharge moisture and gas generated by the decomposition, and further, the drive control of the agitation motor M periodically agitates the carrier A inside the processing tank 1 and takes air into the carrier A, It is carried out intermittently to release moisture and gas produced in the carrier A. By such a control operation, the inside of the treatment tank 1 is maintained in an environment suitable for the activity of microorganisms living in the carrier A, and the organic matter taken into the carrier A leaves a small amount of composted residue. It is decomposed into a gas mainly composed of carbon dioxide and water.
[0043]
On the other hand, as the above operation is continued, in the carrier A inside the treatment tank 1, the residue after decomposition and the hard-to-decompose materials (plastic bags, disposable chopsticks, shells, etc.) that are put together with organic matter are accumulated. Since the habitat environment of microorganisms in the carrier A is deteriorated and the processing capacity is lowered, it is necessary to replace the deteriorated carrier A.
[0044]
In this exchange, first, the deteriorated carrier A inside the processing tank 1 is taken out. For this removal, after removing the outer cover 6 and opening the outlet 25 on the front surface of the lower case 2a, the shutter 5 is removed and the outlet 17 on the lower front surface of the processing tank 1 is opened. A is dropped onto the discharge chute 23 through the discharge port 17 and scraped forward along the inclination of the discharge chute 23.
[0045]
After the carrier A has been taken out in this way, first, the shutter 5 is attached and the discharge port 17 is closed, and then the outer cover 6 is attached and the take-out port 25 is closed. A new carrier A is charged. After the replacement in this way, the organic matter treatment can be performed by resuming the operation described above.
[0046]
When the carrier A is replaced as described above, the discharge port 17 formed at the bottom of the processing tank 1 for taking out the deteriorated carrier A has an opening area as large as possible so that the removal can be easily performed. It is formed. FIG. 8 is a perspective view of the take-out port 25 provided in the front surface of the lower case 2a as viewed from the front. FIG. 8A shows a state where the outer cover 6 and the shutter 5 are removed, and FIG. 8B shows a state where only the shutter 5 is attached. The discharge port 17 is shown in FIG. As shown in the figure, a rectangular opening is formed at the bottom of the processing tank 1 that can be seen from the take-out port 25 over substantially the entire width thereof.
[0047]
The discharge port 17 thus opened has the weight of the carrier A inside the processing tank 1 and the stirring member 4 during the above-described operation performed with the shutter 5 closed as shown in FIG. Is applied to the carrier A by stirring, and the peripheral edge thereof, in particular, the lower and upper edges, which are long, are bent and deformed. In the present invention, the shutter 5 is used to prevent the bending deformation.

FIG. 9 is an external perspective view of the shutter 5, and shows the rear side at the time of mounting shown in FIG. 2 as the front side. As shown in the figure, the shutter 5 includes a lid plate 50 bent in an arc shape so as to correspond to the bottom surface of the processing tank 1, a side plate 51 that borders the periphery of the lid plate 50, and one of the lid plates 50. This is a resin-molded product including a front plate 52 continuously provided on the side and a handle 53 integrally protruding on the other surface of the front plate 52. The cover plate 50 is reinforced from the back by the side plate 51 that borders the four sides, and reinforcing ribs (shown by broken lines in the drawing) between them, and acting force applied to the surface of the cover plate 50 It has a sufficient strength.
[0049]
As shown in FIG. 8A, both sides (only one side is shown) of the discharge chute 23 formed integrally with the lower case 2a so as to face the discharge port 17 from the lower side are substantially horizontal at the lower position of the discharge port 17. A plurality of guide ribs 24, 24... Are projected, and the shutter 5 supports the lower edges of the side plates 51 on both sides of the cover plate 50 by the guide ribs 24, 24. When it is slidable and pushed to the last position, the mounting state as shown in FIG. 2 is obtained, and the protrusion 50a (see FIG. 9) protruding from the surface of the lid plate 50 is fitted, The discharge port 17 is closed.
[0050]
As shown in FIG. 2, the mounting posture of the shutter 5 obtained in this way is such that when the outer cover 6 is mounted to the take-out port 25, a part of the outer cover 6 fits between the lower case 2 a and the shutter 5. It is restrained by inserting. This constraint can be realized by appropriate means such as screwing a part of the shutter 5 to the outer surface of the processing tank 1.
[0051]
FIG. 10 is an enlarged cross-sectional view of the vicinity of the discharge port 17 opened by removing the outer cover 6 and the shutter 5. As shown in the figure, the lower case 2a is integrally formed with a support rib 26 formed on the inner back side of the discharge chute 23 with the upper flat surface facing the lower side of the rear edge of the discharge port 17. I have. As shown in FIG. 8A, a plurality of the support ribs 26 are arranged over the entire width of the discharge chute 23, and a recess having a predetermined height between each upper surface and the bottom surface of the treatment tank 1. Is formed. The height dimension of the recess corresponds to the height of the side plate 51 at the rear end of the shutter 5 having the form shown in FIG. 9, and when the shutter 5 is mounted as shown in FIG. The end is fitted into the recess.
[0052]
As a result, the rear edge portion of the discharge port 17 is supported by the lower case 2a via a part (rear edge portion) of the shutter 5, and the bending of the rear edge portion as described above is caused by the shutter 5 and the lower case. It can be effectively suppressed by the rigidity of 2a. Similarly, the side edge and the upper edge of the discharge port 17 are also supported by the lower case 2 a by the guide ribs 24, 24... On both sides of the discharge chute 23 and the side plate 51 of the shutter 5. Overall deflection can be suppressed. Furthermore, since the position of the shutter 5 is restricted by the action of the outer case 6 as described above, there is no possibility that the effect of preventing the deflection of the periphery of the discharge port 17 is impaired.
[0053]
As shown in FIG. 10, the front portion of the processing tank 1 is connected to the upper case 2 b via the connecting plate 7 in the vicinity of the upper edge of the discharge port 17. At the upper edge of the discharge port 17, due to the acting force from the inside of the treatment tank 1, the downward deformation as described above occurs as well as the forward deformation as described above. This deformation is caused by the upper case formed by the connecting plate 7. Mitigated by linking with 2b.
[0054]
【The invention's effect】
As described above in detail, in the organic matter processing apparatus according to the present invention, the peripheral edge portion of the discharge port opened at the bottom of the processing tank is configured to be supported by the high-strength lower case via a shutter that opens and closes the processing port. The deflection of the peripheral edge of the discharge port caused by the weight of the carrier inside the tank and the action force accompanying the stirring of the carrier can be suppressed without any treatment on the side of the processing tank due to the rigidity of the shutter and the lower case.
[0055]
Furthermore, since the means for restraining the shutter is provided at a position that supports the peripheral edge of the discharge port, the closed state of the discharge port by the shutter can be satisfactorily maintained over a long period of time while suppressing the bending. The invention has an excellent effect.
