Description

【０００１】
【発明の属する技術分野】
この発明は、有機物に対する微生物の分解能力を利用してなされる生ゴミ処理機に関し、更に詳しくは、当該処理に使用される微生物が循環使用される循環式の生ゴミ処理機に関する。
【０００２】
【従来の技術】
この種の微生物を使用する生ゴミ処理機には、従来よりいわゆるバイオコンポスト型及びバイオ消費型がある。
これらのものは、微生物を住まわせる母材（菌の担持体）に杉のチップを用いる場合が多く、母材に付き日処理量の４〜６倍の量が投入され、微生物も日処理量の１〜２倍が投入され、温度は２５〜７５℃とされる。
しかしながら、この種の生ゴミ処理機は、
1)生ゴミの水分を十分に切ることが必要で、その前処理が煩雑である。
2)温度管理に厳格性を要し、高温状態が持続すると乾燥状態となり微生物が死滅し、再始動の手間がかかる。また、低温であると湿潤過多となり、不衛生となり、機械装置の誤動作要因となる。
3)母材の投入量が多いうえに、短期間のうちに母材の全部取替えが必要となり、維持費用が嵩む。
等の種々の不具合がある。
【０００３】
【発明が解決しようとする課題】
本発明は上記実情に鑑みなされたものであり、微生物を利用する生ゴミ処理に付き、母材の投入量の削減をなすとともに、生ゴミの処理能力の増大を図り、かつ、生ゴミの水切りの負担を可及的に無くし、更には温度管理を容易に行うことのできる湿式微生物生ゴミ処理機を提供することを目的とする。
【０００４】
【課題を解決するための手段】
本発明の微生物循環式生ゴミ処理機は、請求項１に記載のとおり、微生物を使用して生ゴミの分解処理がなされる生ゴミ処理機において、生ゴミが投入される攪拌翼を備えた処理槽と、該処理槽の下部に配されるとともに、処理槽からの処理済液が貯留される貯水槽、とを備え、前記処理槽の下部及び前記貯水槽の外側に処理済液を所定温度に保持する電気発熱体よりなる加熱手段が配され、前記処理槽には給水管からの給水を受けて該処理槽内に散水する散水手段が配され、前記貯水槽には該貯水槽の上部から貯留液体の溢出流を導く排水管が取り付けられるとともに、他の給水管が該貯水槽及び前記排出管にそれぞれ接続され、該他の給水管からの給水により前記貯水槽中の処理済液を希釈するとともに、前記排水管中の処理済液を希釈し、前記貯水槽の貯留液体を前記処理槽に還流する還流手段を備えてなることを特徴とする。
上記構成において、 1) 排水管並びに貯水槽に接続される給水管は、散水手段に接続される給水管から分岐される給水枝管をもってなすこと、 2) 処理槽及び又は貯水槽に臭気を排出する排気管を備え、外部に放出する態様を採ること、 3) 攪拌翼は横型、縦型のいずれの形態に限定されない。
この生ゴミ処理機において、攪拌翼の駆動、散水手段による散水、処理済液の希釈、還流手段による還流、の各動作は制御変量として所定の手順をもって、自動、手動、もしくは半自動等により操作されるものである。更に、制御変量に曝気手段の曝気、加熱手段の加熱が加えられる。
【０００５】
本発明の微生物循環式生ゴミ処理機は更に、請求項３に記載のとおり、微生物を使用して生ゴミの分解処理がなされる生ゴミ処理機において、生ゴミが投入される攪拌翼を備えた処理槽と、該処理槽の下部に配されるとともに、処理槽からの処理済液が貯留される貯水槽、とを備え、前記処理槽の下部及び前記貯水槽の外側には、該貯水槽内の処理済液を２５℃ないし３０℃の温度に保持する電気発熱体よりなる加熱手段が配され、前記処理槽には給水管からの給水を受けて該処理槽内に散水する散水手段が配され、前記貯水槽には該貯水槽の上部から貯留液体の溢出流を導く排水管が取り付けられるとともに、他の給水管が該貯水槽及び前記排出管にそれぞれ接続され、該他の給水管からの給水により前記貯水槽中の処理済液を希釈するとともに、前記排水管中の処理済液を希釈し、前記貯水槽には該貯水槽内の処理済液に酸素を送る曝気手段を有し、前記貯水槽の貯留液体を前記処理槽に還流する還流手段を備えてなることを特徴とする。
【０００６】
本発明は更に、上記生ゴミ処理機における処理方法を与える。すなわち、微生物を使用して生ゴミの分解処理がなされる生ゴミ処理機において、生ゴミが投入される攪拌翼を備えた処理槽、該処理槽の下部に配されるとともに、処理槽からの処理済液が貯留される貯水槽、とを備え、前記処理槽には給水管からの給水を受けて該処理槽内に散水する散水手段が配され、前記貯水槽には該貯水槽の上部から貯留液体の溢出流を導く排水管が取り付けられるとともに、他の給水管が該貯水槽に接続され、他の給水管からの給水により前記処理済液を希釈するとともに、前記貯水槽の貯留液体を前記処理槽に還流する還流手段を備えてなる、生ゴミ処理機を使用してなされる生ゴミの処理方法であって、前記攪拌翼の駆動とともに、前記散水手段による散水、前記他の給水管による希釈給水、前記還流手段による還流、の各動作を制御して生ゴミを自動的に処理することを特徴とする。
上記構成において、攪拌翼の駆動、散水手段による散水、処理済液の希釈、還流手段による還流、は制御変量として所定の制御方式・手順をもって操作されるものである。更に、制御変量に曝気手段の曝気、加熱手段の加熱が加えられる。上記の各制御変量の関係及び処理手順は以下の実施形態で具体的に述べられるが、それに限定されるものではなく、実現可能な種々の態様が採られうる。
以下はその制御方法の例示である。
1)各制御変量を時間をもって制御する。すなわち、攪拌翼の駆動時間に対応して、散水・希釈・還流の所定の単位供給量のもとに所要の時間にわたって供給すること。この場合、生ゴミの量はほぼ一定とされる。シーケンス制御はこの制御方法の一態様である。
2)処理の対象となる生ゴミの投入量に応じて制御変量を時間及び量において可変的に制御する。センサーによる検出値に基づいてなされる制御変量の制御はその一例であり、いわゆるプログラム制御を採る。
3)排水濃度を所定値に保って各制御変量を操作する。
【０００７】
（作用）
処理槽に微生物の担持体とともに生ゴミが投入され、攪拌翼により一定時間攪拌され、更に、散水手段によって清水が散布される。生ゴミの含有水分・散水は処理槽の底部よりその下の貯水槽に落下し、貯留される。この貯留水には微生物が含まれている。
貯留水が次第に増加し、その液位が上昇し、上部にまで達すると排水管に溢れ出し、排水される。排水管には給水管を介して清水が注入され、希釈される。また、貯留槽内の貯留水に清水が注入され、貯水槽においても希釈される。そして、貯水槽内の希釈は一定値までに留められる。
この間、適宜貯留槽から貯留槽内の処理済液が処理槽に還流手段を介して還流される。処理槽に一定濃度を保持する処理済液が還流される。
曝気手段からは処理済液に酸素が吹き込まれ、微生物を活性化する。
また、加熱手段により貯留水は適温に保持され、これによっても微生物を活性化する。特に、処理槽の下部からの加熱により、処理槽中の微生物は活性化され、処理効率が高まる。
更に、この加熱は生ゴミに直接触れるものではなく、槽を介して間接的に加熱され、生ゴミに均一に作用し、容易に微生物に適した温度に調整することができる。
【０００８】
【発明の実施の形態】
本発明の湿式微生物循環式生ゴミ処理機の実施の形態を図面に基づいて説明する。
図１〜図１１は本発明の湿式微生物循環式生ゴミ処理機（以下単に「生ゴミ処理機」という）の一実施形態を示す。すなわち、図１はその全体構成を示し、図２〜図４はその要部の構成を示し、図５〜図１１は配管並びに回路構成を示す。
【０００９】
本実施形態の生ゴミ処理機Ｓは、四角箱状のケース１において、内部空間の中央に設置した仕切り壁２をもって処理部３と機械部４とに区画され、該処理部３は上下に、上部の処理槽６と下部の貯水槽７とに区画されてなる。処理槽６の上部には開閉蓋８が開閉可能に配され、該ケース１は開閉蓋８を閉じた状態において全体的に密閉状態を保持する。
なお、本実施形態のケース１は、鋼製の柱材並びに梁材からなる骨組体１ａと該骨組体１ａの外側に貼着される板体（パネル）１ｂとにより形成されてなるが、その構造・材質は本発明にとって非本質的事項であり、他の構造・材質を除外するものではない。また、１ｃは脚部である。
更に、仕切り壁２は処理部３と機械部４とを水密かつ気密に区画するものであって、その位置に限定されず、処理部３と機械部４との容量によって決定される。
【００１０】
そして、処理槽６には攪拌手段１０、散水管１１及び循環水放出管１２が配され、それぞれ機械部４の攪拌駆動装置、給水管、循環ポンプに連なる。また、貯水槽７には上部に溢流口１４が、下部に排出口１５が開口され、これらの開口１４，１５は機械部４の排水管に連なり、更に該貯水槽７内に、希釈管１６、循環水吸入管１７及び曝気管１８が配され、それぞれ機械部４の給水管、揚液ポンプ、曝気ポンプに連なる。更にまた、貯水槽７の周囲並びに処理槽６の底部に加熱体が配される。
しかして、本生ゴミ処理機Ｓには、攪拌手段１０に連動する攪拌系と、散水管１１、希釈管１６に連なる給水・希釈系と、溢流口１４及び排出口１５に連なる排水系と、処理槽６と貯水槽７との間の循環系、更には、曝気管１８に連なる曝気系、貯水槽７の加熱体に連なる加熱系の各系統が配されることになる。
【００１１】
以下、上記の各主要部材並びに各系統の細部構造に付いて説明する。
処理槽６
処理槽６は、内部に投入された生ゴミを分解処理するものであり、攪拌手段１０、散水管１１及び循環水放出管１２が配される。処理槽６は水密を保つ槽本体２０よりなり、底部に小孔６ａが多数開設され、水分は該小孔６ａを介して下方の貯水槽７へ滴下する。
【００１２】
（攪拌系）
処理槽６の内部には攪拌手段１０が配され、攪拌手段１０は回転軸２１に攪拌翼２２が複数箇所（本実施形態では３か所）にわたって取り付けられる。攪拌翼２２は処理槽６の処理容量に応じて自在に設けられ、その数に限定されない。回転軸２１は槽本体２０を水密を保持して貫通し、両側の軸受２３によって回転自在に支持され、機械部４側の端部には大歯車２４が取り付けられる。
一方、機械部４の上部において、電動モータ２６が配され、該モータ２６は減速装置２７を介してその駆動回転軸に小歯車２８が取り付けられ、大歯車２４に噛合する。この駆動機構は減速機構であって、大きな負荷に対応する。
この駆動・伝動機構の歯車構造に替え、チェーン、べルト伝動、更には他の適宜の伝動構造を採ることを妨げない。
【００１３】
（給水・希釈系）
処理槽６内に配される散水管１１は、多数の小孔１１ａが開設され、これらの孔１１ａより処理槽６内に散水する。該散水管は処理槽６の本体２０を貫通して機械部４内に導かれ、水道管Ｗに連通して該水道管Ｗから所定水圧をもって給水される給水主管３０に連なる。給水主管３０においては電磁式の調整弁３１が途中に介装され、調整弁３１の開閉動作を受けて散水される。
給水主管３０には、上流側より調整弁３１に至る前に、上部より２つの枝管、すなわち、第１給水枝管３３、第２給水枝管３４がそれぞれ分岐される。
第１給水枝管３３は途中に電磁式の調整弁３５が介装され、後記する排水主管に連通する。第１給水枝管から排水主管へ清水が供給されて、排水主管を介して排出される処理済液の希釈をなす。
第２給水枝管３４は途中に電磁式の調整弁３６が介装され、貯留室７内希釈管１６に導通する。第２給水枝管３４は貯水槽７の処理済液の希釈化作用をなすとともに、貯水槽７の清掃用に供される。
調整弁３１，３５，３６の上流側に手動による開閉弁（常時開）が配されることは適宜採択される設計的事項である。また、本給水・希釈系では給水主管３０より枝管３３，３４がそれぞれ分岐する態様を示したが、枝管３３，３４は各別に水道管Ｗより給水され、いずれかが独立してもよい。
なお、第２給水枝管３４の調整弁３６を迂回して、その間に手動弁を有するバイパス管を配することも適宜なしうる設計的事項である。これにより貯水槽７の清掃用に供する。
更に、給水源を公共の水道管Ｗに採る場合、当該水道水の残留塩素を除去するフィルターを経由して本給水本管３０に接続することは適宜採択される設計的配慮である。
【００１４】
貯水槽７
貯水槽７は、水密を保持する槽本体４０をもって、処理槽６の下部に配される。
貯水槽７には、処理槽６より排出された処理菌の含有された液体すなわち処理済液が貯留され、排水系をもってこの貯留液体の液位を保持し、給水・希釈系をもって処理済液の希釈を行い、循環系をもって貯留液体の一部を処理槽６へ還流し、更には、曝気系をもって貯留液体の曝気をなす。また、槽本体４０の外側には加熱手段が装着される。
【００１５】
（排水系）
貯水槽７の上位に開口する溢流口１４は機械部４内に配された大径の排水主管４１に連なる。
貯水槽７の下部には排水口１５が開設され、排水予備管４２を介して排水主管４１に連通する。
排水主管４１はその下流の汚水処理装置を介して又は介さずして公共下水道管へ接続される。本実施形態では排水主管４１と排水予備管４２とは末端で結合されたものとなっているが、各独立して外部に排出されるようにされたもよい。
もっと詳しくは、溢流口１４に連なる排水主管４１はほぼ水平状に保持され、あるいは下流側に向けて緩傾斜を附され、溢流口１４から流出する処理済液を緩やかに流出させ、その途中に前記した第１給水枝管３３が接続され、該第１給水枝管３３から清水の補給を受ける。これにより排水主管４１を流れる処理済液の希釈化をなす。
排水口１５に連なる排水予備管４２は、その途中に電動式の開閉弁４３が介装され、この電動開閉弁４３は常時は閉弁され、貯水装置７内の液体を急速排水する場合に開弁される。該開閉弁４３はタイマーに接続され、週間単位をもって一時的に作動する。この開閉弁４３が作動する際、第２給水枝管３４の電磁調整弁３６の作動により清水が供給され、希釈管１６より吐出されて貯水槽７内を清掃する。
【００１６】
（循環系）
循環系を構成する還流手段は、処理槽６と貯水槽７とにわたって配され、処理槽６内の循環水放出管１２と、貯水槽７内の循環水吸入管１７と、これらの管１２，１７の途中に介装される揚液ポンプ（バイオポンプ）４５と、からなる。
揚液ポンプ４５は電動式で、その作動により循環水吸入管１７から貯留水を吸引し、配管を介して処理槽６内の循環水放出管１２から処理済液を放出する。また、途中に電磁式のバルブ（バイオバルブ）４６が介装され、その電磁操作により、循環液の供給量と時期とを自在に調整する。
この環流手段により、貯水槽７の処理済液は上方の処理槽６へ所定時期・所定量にわたって還流され、しかる後処理槽６から貯水槽７へと滴下し、循環作用をなす。
【００１７】
（曝気系）
曝気系は、曝気管１８、曝気ポンプ４７及びフィルター４８、の各構成要素からなる。すなわち、曝気管１８は貯水槽７の中央部下方部に長手方向に配され、上手部に気体が噴出する小孔が多数開設されてなる。該曝気管１８は機械部４内の曝気ポンプ４７に接続される。該曝気ポンプ４７は電動式で、その駆動によりフィルター４８を介して取り入れられた空気を曝気管に圧送する。曝気管１８より送り出される空気、就中、酸素により貯留水Ｈ中の微生物は活性化する。
（保温手段）
処理槽６の下部、及び少なくとも貯水槽７の外側に、加熱手段（ヒーター）５０が配される。すなわち、該加熱手段は電気発熱体、すなわちニクロム線を主体とし、温度調節材、温度検知器が付加されるとともに、防水手段が施される。該加熱手段５０をもって、貯水槽７内の貯留水Ｈの温度を２５℃〜３０℃に保つ。
【００１８】
その他
（排気手段）
処理槽６に排気手段として電動式のファン（ＦＡＮ）が外付けで取り付けられる。すなわち、処理槽６内の臭気を電動式のファンの駆動により配管を持って吸い出し、外部へ放出する。電動ファンが介装される配管は排水主管４１に接続され、その臭気を排水主管４１を介して排出する態様を採ることもできる。
【００１９】
（設定）
本生ゴミ処理機Ｓの駆動は主として電動・電磁式を採り、所定の制御方式に基づいて駆動されるが、手動を除外するものではない。
その制御方式・手順は、以下の記述のとおりシーケンス制御方式を採り、自動的になされるので人手を省け、省力化を図れ、便利であるが、適宜手作動によることは勿論差し支えない。更に、シーケンス制御によらず、コンピュータによるプログラム制御によることもできる。
本生ゴミ処理機Ｓの給水系は外部の水道管Ｗに接続され、排水系は外部の下水道管に接続される。また、電気系は外部電源より供給される。
【００２０】

本生ゴミ処理機Ｓの採る諸元の一例を示す。
すなわち、標準型として、標準処理能力（日量）５０kg、菌担持体（籾がら）投入量約４７３リットル、処理槽６の容量約１０００リットル、貯水槽７の容量約２００リットル、を採る。

当該電気系において制御手順が具体化されたものであり、いわゆるシーケンス制御を採る。これにより、本生ゴミ処理装置Ｓの操作は自動化され、人手を介さず、大きな利便性を得る。
【００２７】
本実施形態の生ゴミ処理装置Ｓの使用態様並びに作用に付いて説明する。
ここに述べられる生ゴミ処理装置Ｓは先に述べた標準型（日標準処理５０kg、最大処理８６kg）を想定し、微生物は好気性菌もしくは通気嫌気性菌を使用し、微生物の担持体に籾がらを使用する。
以下、工程順に従って述べる。
【００２８】
(1) 先ず、本生ゴミ処理装置Ｓの処理槽６内に微生物の担持体とともに生ゴミがそれぞれ所定量投入される。微生物の担持体として所定量の籾がらが投入され、生ゴミは日処理量に従って所定量投入される。その目安として、攪拌手段１０の回転軸２１がやや埋まる程度（約１０cm）とされる。
【００２９】
(2) 攪拌手段１０を作動し、その攪拌翼２２により生ゴミと担持体とを一定時間攪拌させる。更に、散水手段１１によって生ゴミに清水が散布される。微生物は生ゴミに作用し、分解していく。生ゴミの含有水分・散水は処理槽６の底部の小孔６ａよりその下の貯水槽７に落下し、処理済液として貯留される。この貯留水Ｈには微生物が含まれている。
攪拌手段１０は一定時間作動したのち、休止し、間欠動作を採るものとするが、この態様に限定されない。また、散水手段１１による散水はその散水量にもよるが、標準的には攪拌時間よりも短めになされるが、これに限定されない。
【００３０】
(3) 貯水槽７において、貯留水Ｈが次第に増加し、その液位が上昇し、上部にまで達すると排水主管４１に溢れ出し、排水される。排水主管４１には第１給水枝管３３より所定量の清水が注入され、希釈される。また、貯水槽７内においても、貯留水Ｈに第２給水枝管３４より希釈管１６をもって所定量の清水が注入され、貯水槽７においても希釈される。排水主管４１からの排水は、本処理装置Ｓの外部へ排出され、下水管へ流出される。
なお、排水主管４１への第１給水枝管３３による注水は攪拌手段１１の攪拌が終了した時点でなすことも一態様である。
【００３１】
(4) 一方、貯水槽７の貯留水Ｈは、揚液ポンプ４５の作動により、循環水吸入管１７から吸い込まれ、配管を介して上方の処理槽６へ送られ、該処理槽６の循環水放出管１２より処理槽６内へ散布される。
揚液ポンプ４５の作動は、その揚液量にもよるが、攪拌手段１０の攪拌動作と同時並行的になされる態様を採るものであるが、これに限定されない。
【００３２】
(5) この間、貯水槽７の貯留水Ｈは、送気ポンプ４７の作動により、フィルター４８を介して取り込まれた空気、就中、酸素を曝気管１８を介して曝気作用を受け、微生物の活性化を促進する。好気性菌の増殖に寄与する。
また、加熱手段（ヒーター）５０により保温され、微生物を保持し、排気ファンも作動し、処理槽６内の臭気を外部に排出する。
これらの曝気作用並びに加熱作用は持続的になされる。
【００３３】
(6) 上記の工程により、生ゴミは遂時分解処理され、処理槽６内での容量を減少させる。
しかる後、更に生ゴミが投入される。
この生ゴミの投入に際しては、攪拌手段１０による攪拌動作は停止され、同時に散水手段１１による散水並びに循環水放出管１２からの微生物含有液の散布は停止される。一方、送気ポンプ４７による曝気操作、ヒーター５０による加熱操作、排気ファンによる排気操作は持続される。
【００３４】
(7) 叙上の工程、すなわち初期工程(1) を除き、(2) 〜(6) の工程を繰り返し、引き続き投入される生ゴミも叙上の過程を経て、処理される。
この間、籾がらの減少に応じて適時に補給される。
【００３５】
(8) 上記の工程において、所定期間、例えば１か月が経過すると、貯水槽７の清掃が行われる。すなわち、予備排水管４２の電動開閉弁４３が開弁され、その排出作用をもって貯留水Ｈは予備排水管４２・排水主管を介して外部に排出される。
同時に、第２給水枝管３４を介して希釈管１６より清水が吐出され、貯水槽７を洗浄する。
この工程の後、適宜の工程に復帰する。
【００３６】
叙上の工程において、処理槽６及び貯水槽７は湿式環境を保持し、かつ曝気作用を受けるので、微生物は好気性を発揮し、好気性菌が増殖し、良好な分解処理をなすばかりでなく、悪臭を出すことはない。
【００３７】
図１０・図１１はこの生ゴミ処理機Ｓの作動の一例を示すタイムチャートである。すなわち、本機Ｓは所定のプログラムに従って作動する。

  The garbage disposal apparatus S described here is assumed to be the standard type described above (daily standard treatment 50 kg, maximum treatment 86 kg), and microorganisms use aerobic bacteria or aerated anaerobic bacteria. Use backlash.
  Hereinafter, it will be described in the order of steps.
[0028]
(1) First, a predetermined amount of garbage is put into the treatment tank 6 of the garbage treatment apparatus S together with a microorganism carrier. A predetermined amount of straw is input as a microorganism carrier, and a predetermined amount of garbage is input according to the daily treatment amount. As a guide, the rotating shaft 21 of the stirring means 10 is slightly filled (about 10 cm).
[0029]
(2) The agitation means 10 is operated, and the garbage and the carrier are agitated for a certain time by the agitation blade 22. Further, fresh water is sprayed on the garbage by the watering means 11. Microorganisms act on garbage and decompose. The moisture and water spray contained in the garbage fall from the small hole 6a at the bottom of the treatment tank 6 to the water storage tank 7 below and stored as a treated liquid. This stored water H contains microorganisms.
  The stirring means 10 operates for a certain period of time, then pauses and takes an intermittent operation, but is not limited to this mode. Moreover, although the watering by the watering means 11 depends on the amount of watering, it is typically shorter than the stirring time, but is not limited thereto.
[0030]
(3) In the water storage tank 7, the stored water H gradually increases, the liquid level rises, and when it reaches the upper part, it overflows into the drain main pipe 41 and is drained. A predetermined amount of fresh water is poured into the drain main pipe 41 from the first water supply branch pipe 33 and diluted. Also in the water tank 7, a predetermined amount of fresh water is injected into the stored water H through the dilution pipe 16 from the second water supply branch pipe 34 and diluted in the water tank 7. Drainage from the drainage main pipe 41 is discharged to the outside of the processing apparatus S and flows out to the sewer pipe.
  In addition, it is one mode that water is poured into the drainage main pipe 41 by the first water supply branch pipe 33 at the time when the stirring of the stirring means 11 is completed.
[0031]
(4) On the other hand, the stored water H in the water storage tank 7 is sucked from the circulating water suction pipe 17 by the operation of the pumping pump 45 and is sent to the upper processing tank 6 through the pipe. The water is discharged from the water discharge pipe 12 into the treatment tank 6.
  Although the operation of the pumping pump 45 depends on the amount of pumped liquid, the operation is performed in parallel with the stirring operation of the stirring means 10, but is not limited thereto.
[0032]
(5) During this time, the stored water H in the water tank 7 is subjected to the aeration action of the air taken in through the filter 48, especially oxygen, through the aeration pipe 18 by the operation of the air supply pump 47, Promote activation. Contributes to the growth of aerobic bacteria.
  Further, the temperature is maintained by the heating means (heater) 50, the microorganisms are retained, the exhaust fan is also operated, and the odor in the processing tank 6 is discharged to the outside.
  These aeration action and heating action are performed continuously.
[0033]
(6) By the above process, the garbage is finally decomposed and the capacity in the processing tank 6 is reduced.
  After that, further garbage is thrown in.
  When charging the garbage, the stirring operation by the stirring means 10 is stopped, and at the same time, spraying by the watering means 11 and spraying of the microorganism-containing liquid from the circulating water discharge pipe 12 are stopped. On the other hand, the aeration operation by the air supply pump 47, the heating operation by the heater 50, and the exhaust operation by the exhaust fan are continued.
[0034]
(7) Except for the above process, that is, the initial process (1), the processes of (2) to (6) are repeated, and the garbage that is subsequently input is also processed through the above process.
  During this time, it is replenished in a timely manner according to the reduction of the cracks.
[0035]
(8) In the above process, when a predetermined period, for example, one month elapses, the water tank 7 is cleaned. That is, the preliminary drain pipe42Electric on-off valve43Is opened, and with its discharge action, the stored water H is a preliminary drain pipe.42・ It is discharged to the outside through the drain main pipe.
  At the same time, fresh water is discharged from the dilution pipe 16 through the second water supply branch pipe 34 to wash the water storage tank 7.
  After this step, the process returns to an appropriate step.
[0036]
  In the above process, the treatment tank 6 and the water storage tank 7 maintain a wet environment and are subjected to an aeration action, so that the microorganisms exhibit aerobic properties, the aerobic bacteria grow, and a good decomposition treatment is performed. There is no stink.
[0037]
  10 and 11 are time charts showing an example of the operation of the garbage processing machine S. FIG. That is, the machine S operates according to a predetermined program.
  As can be seen from these figures, the agitator and biopump are each operated for 30 minutes, the water injection valve, the watering valve and the water supply valve are each operated for 10 minutes, the heater, the aeration pump and the exhaust fan are each continuously operated, and the forced drain valve is Take temporary action at a specified date and time.
  With the start, the heater temperature control is turned on, and the aeration pump and the exhaust fan are also turned on.
  When the inlet is closed, the proximity switch is closed (on), the agitator and the biopump continue to operate, and at the same time the watering valve and the water supply valve operate.
  After 30 minutes, the agitator and the biopump are stopped, and then the water injection valve is activated (10 minutes). When the water injection valve stops, the garbage truck will be in a steady state, and the heater, aeration pump, and exhaust fan will continue to operate.
  After 60 minutes, the above operation is repeated.
[0038]
  When the garbage is thrown in, the slot is opened, the proximity switch is turned off, the heater, the aeration pump, and the exhaust fan operate, but the others are turned off.
  When the slot is closed, the above operation is repeated when the proximity switch is turned on again.
  During this process, when the predetermined time and date set in advance is reached by the timer, the forced drain valve is turned on and the water in the water tank is discharged.
[0039]
  The operation of the garbage disposal machine S is not limited to the above-described mode.
  That is, the operating time of each operating device (actuator) is not limited to the above time and is free. Therefore, although one cycle is 60 minutes, it is not limited to this.
[0040]
  The garbage processing machine S of the present embodiment has the above-described configuration and has an effect, and thus has the following effects.
  Microorganisms operate in a wet environment through the treatment tank 6 and the water storage tank 7 and circulate through the treatment tank 6 and the water storage tank 7, so that the microorganisms are used effectively, the decomposition treatment capacity is improved, and garbage is collected. Organic matter is decomposed and extinguished in the stored water H, and the volume reduction rate of garbage is 100%. Also, it is not necessary to drain the garbage.
  Microorganisms are circulated and aerobic and microorganisms are aerobic due to aeration and heat retention. The aerobic bacteria grow, the consumption of microorganisms is reduced, and it is not necessary to replace the bacterial carrier. The time is significantly prolonged and maintenance costs are reduced.
  Since the odor in the treatment tank 6 comes into contact with the water supplied by the water supply and is dissolved in the water, the odor hardly escapes to the outside.
  Since the stored water H in the water tank 7 is diluted with fresh water, it does not adversely affect the discharge to the outside, and in addition, it is also diluted in the drainage main pipe 41, thus effectively preventing environmental pollution. Is done.
[0041]
  The present invention is not limited to the embodiment described above, and various design changes can be made within the scope of the basic technical idea of the present invention. That is, the following aspects are included in the technical scope of the present invention.
1) Although the stirring means 10 of the treatment tank 6 takes a horizontal form, it may be a vertical form. In this case, the tank body of the processing tank 6 is cylindrical.
2) The drainage preliminary pipe 42 is a non-essential matter for the present invention, and the installation of a forced drainage valve in the drainage preliminary pipe 42 can be omitted.
3) As the fungus carrier, appropriate ones such as potatoes, cedar chips, sawdust, etc. can be adopted.
[0042]
【The invention's effect】
  Microorganisms operate in a wet environment through treatment tanks and water storage tanks, and circulate through the treatment tanks and water storage tanks. Therefore, microorganisms for garbage are effectively used, the decomposition treatment capacity is improved, and the organic matter in garbage Is decomposed and extinguished in the stored water, and the volume reduction rate of garbage can reach 100%. Also, it is not necessary to drain the garbage.
  Since microorganisms are circulated and used, the consumption of microorganisms is reduced, there is no need to replace the fungus carrier, and the maintenance cost is reduced.Since the treated liquid returned to the treatment tank is appropriately diluted in the water storage tank, the concentration of the treated liquid is not greatly changed, and the concentration management is easy.
  The odor in the treatment tank comes into contact with the water supplied by the water supply and is dissolved in the water, so that the odor hardly escapes to the outside.
  Since the water stored in the water tank is diluted with fresh water, it does not adversely affect the discharge to the outside, and in addition, it is also diluted in the drain pipe, so that environmental pollution is effectively prevented.
That is, when the dilution in the water storage tank is insufficient, the overflow flow is further diluted in the drain pipe, and the discharge standard can be easily satisfied. For this reason, the dilution degree in a water storage tank can be kept to a fixed value, and the processed liquid of a fixed density | concentration can be returned to the upper process tank.
As a result, in the garbage processing machine having this container shape, the concentration of the processed liquid is kept constant, and no other special diluting device for discharging such as a combined processing tank is required, and the discharging is performed. Can be made.
