Description

【０００１】
【発明の属する技術分野】
本発明は、生ごみを微生物を利用して分解消滅させる処理機に係り、特に地球規模の環境汚染防止に基づく、国際条約批准によるわが国海洋汚染防止法対応の為、地球環境全体から考慮して、省エネルギ−、省スペ−ス、無臭、無排水、消滅という観点から、海洋汚染防止の大局において、船舶搭載に限らず、陸上設備に於ても河川、地下水汚染防止に大きな役割を果たす、微生物による生ごみ処理機に関する。
【０００２】
【従来の技術】
従来、生ごみの処理は、原形生ごみを処理槽に投入し、この生ごみを段階的に消滅するための貯留槽、発酵槽、熟成貯留槽を備えた方式であり、数日単位で定期的発酵助成菌を添加、発酵を促進して有機肥料に変え、数日単位で残渣排出、保管、処分するのが殆どであるので、処理に日数を要していた。
この方式を改善するものとして近年、一槽式の分解処理機と称する生ごみの分解処理機が提案され、分解媒体剤として樹木粉を装填し、発酵促進剤を定期的に処理槽に投入添加し、加熱ヒーターを設置して生ごみの分解処理機能を向上させたものがある。
【０００３】
しかしながら、上記した分解処理機においては、無機ごみに近い卵の殻や魚の骨類は全く分解せず、その上、残飯の粒も分解不能であり、さらに臭気が発生して、蛆虫等の発生もあり、同時に処理槽内発酵分解の必須条件として必ず加熱ヒ−タ−を設置しておりエネルギ−を消費していた。
また、発酵による強烈な複合臭気が発生する為、消臭装置を設置しているが、複合臭的な生ごみ分解臭気は消臭不能に近く、場合によっては、生ごみ処理機と同様の大きさの消臭装置を併設する必要があった。
【０００４】
また、分解能力の低さから、分解媒体材の生ごみの分解に要する必要量も極端に多く、当然ながら処理槽も大きくなり、バイオ剤と称して発酵促進剤を生ごみと共に毎日、或は一定間隔で処理槽に投入する手間もあり、その上、日毎に臭気が増大し、分解度の低さから定期的に残渣を取り出し、残渣処分迄の期間は残渣の保管を要していた。
また、分解した生ごみの取り出し方法においても、人力による袋詰め等の煩雑さを極め、大型になればなるほど発酵助成の為の大きな加熱電力容量を必要とし、機器の大型の為に設置スペ−スを取り、その上攪拌機構に於ても処理槽内の過酷条件を軽視して、単なる攪拌機的感覚に於て製作しているので、機器の安全性に配慮されておらず、、故障の発生率の大きさや、故障時の復旧修理の困難さから、船舶への搭載は不可能であった。
【０００５】
【発明が解決しようとする課題】
従って、従来の技術における課題は、有機生ごみの処理過程で必然的に発生する発酵分解臭気の発生の為、大小各種の消臭装置が付設されているが、複合臭気の為に満足な消臭効果が得られていないのが事実であり、これを分解時間を極限まで短縮し無臭化処理する事が課題であった。
以下、その具体的な課題を説明する。
【０００６】
有機生ごみを分解処理する為には、分解媒体材の主たる基材を木粉にしているので、生ごみ１日当たり処理１Ｋｇに対して５０リットル以上の大量の分解媒体材を要し、発酵加湿による分解媒体剤の水分が多い為に、処理機の大型化と、含水率が大である為の攪拌機トルクの増大による駆動装置の騒音と消費電力が増大するという問題があった。
【０００７】
原形生ごみの処理は発酵処理である為、水分と温度が必要となり、通常においても加熱ヒ−タ−の設置が必然的につきまとい、電力の消費が多大となるものである。また、生ごみ分解水が発生し、処理機外に廃水する事による環境汚染の危険性と分解水臭気の発生が付随していた。
【０００８】
従来の処理機は、生ごみに混入した魚の骨、蟹の甲羅、卵の殻等は分解不能であり、一般生ごみに於ても分解日数を長く要し、処理機の大型化と共に、残渣の処理機からの取り出し、保管、処分が必須条件となっていた。
【０００９】
毎日、または、一定間隔的に投入する発酵促進剤の経費増大、発酵促進剤を誤って使用される危険性があり、又生ごみの処理機への必要以上に投入したり、発酵促進剤を定期的に投入するのを忘れたりすることによる処理効果の低減等も発生していた。
【００１０】
従来の生ごみ処理機は、有機肥料製造機的感覚で製造され、しかも、ここ数年来の生ごみ処理の環境問題から発生したものであり、海洋の様に国際条約による海洋環境保全の法律遵守的な感覚はなく、海洋における実地経験の不足から機構、強度に充分な検討がなされていない為、攪拌装置等の故障が頻発し、処理機故障の場合は殆どの機構が溶接構造の為に、一旦、故障発生の場合は処理機本体を製造工場に持ち帰って修理しなければならなかった。
【００１１】
従来の生ごみ処理機の取扱上の機器安全性は全く無く、ただ単に生ごみ投入口のみの自動発停コントロ−ルであるが、大型処理機の場合は処理槽内部に、掃除、修理等で人間が入る事も必要であり、万一処理槽内に人が入っていた場合の過失による投入口閉鎖と同時に機器稼働の危険性があり、又船舶搭載の場合、荒天動揺により転倒した場合の処理機角部の鋭角も危険極まりなかった。
【００１２】
船舶に搭載した場合、海洋特有の気象条件と、船舶特有の航海条件により、ピッチング（前後の揺れ）、ロ−リング（左右の揺れ）、ウオ−タ−ハンマ−（荒天航行時の船首での波による衝撃）、レシプロメインエンジン・レッドゾ−ン振動（主機関の常用回転到達迄の過大振動）等々による生ごみ処理機電気制御機器の異常発生、又は誤作動、停止等の問題点があった。
【００１３】
生ごみ処理機を実際に使用する厨房担当員の知識不足や経験不足により、また、処理機内部の分解媒体材の過乾燥や過湿度等の判断が目視判断に頼られているため、判断誤認による臭気発散、分解不能等の事故が発生していた。
【００１４】
数日間隔等、一定期間毎の定期的に残渣を処理機から排出する必要があり、船舶はもとより、陸上に設置した場合でも残渣保管、処分等の問題が付随している。従来の生ごみ処理機は、１日の処理能力が６０Ｋｇの場合、それが有機肥料化する処理機で、幅４．５メ−トル、奥行き１．８メ−トル、の床面積を要し、ある生ごみ処理機に於ては、臭気除去の為に、別途に直径１．５メ−トル、高さ２メ−トルにもおよぶ消臭塔の設置を要する為、陸上での設置も困難であり、更に、船舶搭載の為にはスペ−ス的に全く使用できなかった。
【００１５】
冬期に連日マイナス温度が続く場合、船舶の場合は特に、その航路によっては赤道直下の航路、或は北洋航路等の地球の全地域に航路があるため、如何なる環境にも充分効果を発揮しなければならないが、従来の生ごみ処理機は、わが国の冬期北海道の気候にすら対応可能な処理機はなく、本州中部の気候、特に春、秋を標準とした気候にしか対応できてなく、連続マイナス２０℃の環境により分解不能といった問題や、連続５０℃の環境下で多大の臭気発生する等の問題があった。
【００１６】
本発明は上述した従来の問題点に鑑みなされたものにで、分解臭気については、生ごみを破砕して微細化する事により単位重量当たりの表面面積を増大させて分解消滅時間を極限まで短縮し、有機物の分解に必要な分解媒体剤の配合においては、有機物分解土壌菌を配合して残渣を残す事なく継続的に分解消滅を行い、同時に分解媒体材を乾燥状態に維持して、分解に必要な水分は生ごみの持っている水分を利用し、従来の高温発酵菌を使用せず、常温分解微生物の発熱エネルギ−温度によって、人工的に温度を上げる事なく生ごみを常温分解消滅させる、微生物による生ごみ処理機を提供することを目的とする。
【００１７】

【００２１】
【実施の形態】
本発明の実施の形態を図１乃至図４に基づいて説明する。
図１は本発明の微生物による生ごみ消滅機を示す一部破断の側面図、図２は、図１の微生物による生ごみ消滅機の正面図、図３は、図１の微生物による生ごみ消滅機の電気制御盤の断面図、図４は、破砕機の断面図である。
【００２２】
まず、図１および図２において、処理槽（１）は横倒円筒形に耐腐食性の高いステンレスにより形成され、上部位置部分はほぼ水平に開口され、複数の強度部材である支柱（１７）によって処理基台（１８）に固定され、また、処理槽（１）の底部と処理基台（１８）との間は、温度制御付き加温装置（２７）の温風通過の為に間隙をもって設置されている。
この処理槽（１）を横倒型円筒形に形成することは強度が保たれることと、攪拌時に処理槽（１）内の分解媒体材（３８）を完全に攪拌することができ発酵臭気の発生を避けるためである。また、処理槽（１）の前部の上端壁に垂直部を形成し、この垂直部に空気導入口（１１）を設置し、処理槽（１）の後部の上端壁には排気口（１２）を設置し、分解媒体材（３８）の攪拌効率を図っている。
【００２３】
この処理槽（１）内に装填された分解媒体材（３８）は、生ごみの有機分解に有効な好気性微生物が着床された、樹木粉と無機吸湿剤を混合攪拌したものである。この分解媒体材（３８）は、土壌埋設分解消滅の原理を応用して土壌中に生存している有機物分解微生物を抽出培養し、それを土壌の代わりに樹木粉等に着床させたものである。水中分解等の方法で短時日分解は機械的にコスト高となることから、自然界の土壌埋設と同じ原理をとり、土壌の代わりに、樹木粉を使用し、樹木粉の持つ種々の影響物質を加熱して無害化・殺菌することにより、分解菌の着床、増殖温度を向上させるとともに、発芽阻止的効力のあるリグニンサンを分解無能化することによって、有機肥料としての安全性を高めている。分解菌としては好気性菌が使用される。
【００２４】
前記処理槽（１）の両側には、左側処理槽壁（２）と右側処理槽壁（３）が設けられ、この左側処理槽壁（２）と右側処理槽壁（３）の円中心を貫通して攪拌軸（４）が装着されており、右側処理槽壁（３）を貫通した攪拌軸（４）に攪拌軸駆動歯車（５）が固着されるが、この攪拌軸（４）は攪拌軸駆動歯車（５）側は駆動時の攪拌軸（４）の駆動時におけるオ−バ−ハングによる反復応力折損事故をを避ける為と、攪拌軸（４）の駆動側のベアリング（６）の荷重摩耗を防止する意味で、攪拌軸受ベアリング（６ａ），（６ｂ）の２個で受け、攪拌軸の左側は１個の攪拌軸受ベアリング（６ｃ）で受け、回転可能に設置されている。
【００２５】
また、攪拌軸（４）には複数の爪付き湾曲攪拌翼（７）が装着されるが、円筒形軸の攪拌軸（４）の爪付き湾曲攪拌翼（７）が設置される部分には、爪付き湾曲攪拌翼（７）の設置角度毎にキ−溝（８）（図８参照）が旋削加工されており、回り止めキ−付き攪拌翼装着部（９）と攪拌翼装着部（１０）とが複数のボルトによって攪拌軸（４）に装着され、この取り外し可能な爪付き湾曲攪拌翼（７）は、万一の異物混入等の不慮の曲損事故に於ても、処理機本体（１６）の設置現場に於て簡単に交換復旧が可能である。
【００２６】
爪付き湾曲攪拌翼（７）の爪（７ａ）（図８参照）は、処理槽（１）内の攪拌効率を高める為、処理槽（１）内の両側に分散した分解媒体材（３８）を処理槽（１）の中央部に導くものである。そのため、攪拌軸（４）の長さ方向中心に向かっておおよそ約３０度傾斜させている。
また、中央の爪付き湾曲攪拌翼（７）の爪（７ａ）は分解媒体材（３８）を処理槽（１）の左右両端に導く様に配列したものである。
【００２７】
また、攪拌軸（４）の回転方向は、図１に示す様に、矢印方向の時計回りの回転方向にしたが、この意味は本発明の処理槽（１）の取り出し口が正面側下部にある事から処理槽（１）内の分解媒体材（３８）の取り出しを、爪付き湾曲攪拌翼（７）の回転によって容易に自動排出させる為であり、また、攪拌軸（４）の回転は、微速連続回転方式と、間欠回転方式との２方式とし、間欠回転方式の場合は回転時間と停止時間を任意に設定可能な方式にしている。
【００２８】
攪拌軸（４）を駆動する攪拌駆動機（１９）は、処理機台（１８）上に設置され、攪拌駆動機（１９）の駆動歯車（２０）が攪拌軸駆動歯車（５）と噛み合うことにより、攪拌軸（４）を減速して回転させる。
また、攪拌駆動機（１９）を処理槽（１）上部に設置した場合は、駆動歯車（２０）と攪拌軸駆動歯車（５）との距離が大きいのでチェ−ンを使用するチェ−ン駆動とするものである。
【００２９】
また、処理槽（１）前部の上部垂直壁には、処理槽（１１）内の分解媒体材（３８）の水分蒸発補助と新鮮空気の供給の為に複数の空気導入口（１）が設けられ、処理槽（１）の上部に設置された排気ファン（１４）により処理槽（１）内の空気が吸引され、強制的に空気導入口（１１）から新鮮空気が流入して、分解媒体材（３８）の水分、ガス等を排出し、また、処理槽（１）の上部壁の排気口（１２）に続いて、処理槽（１）の外部に粉塵を発散させない為、ろ過装置（１３）と排気ファン（１４）、並びに排気管（１５）によって処理機本体（１６）の外部に排気されている。
【００３０】
処理槽（１）を収納する処理機本体（１６）内には、処理槽（１）に新鮮な空気を供給する為と、分解媒体材（３８）の水分除去の為に、空気供給機（２１）が設置されており、この空気供給機（２１）と接続する空気供給管（２２）が取り付けられている処理槽（１）の貫通部付近には、管掃除口（２３）が設けられて処理槽（１）底部に貫通設置してあり、空気供給管（２２）の処理槽（１）貫通内部端末部には塵埃の流入を防止する為の網（２４）が固着設置されている。この空気供給機（２１）よる処理槽（１）内への空気供給は、生ごみの酸化分解消滅に必要な新鮮な酸素の供給と、過湿による生ごみ臭気の防止、生ごみ分解水の発散の為に行うものである。
【００３１】
処理槽（１）前面下部には、ワンタッチ開閉可能な、じょうご付き取り出し口（２５）が装着されている。
この取り出し口（２５）は処理槽（１）の前面下部に装着された場合は、図１の矢印に示す攪拌軸（４）の回転方向となり、処理槽（１）内の残渣を取り出し易くするが、処理槽（１）の後面下部に設置することも可能であり、この場合の攪拌軸（４）の回転方向は逆になるが、これは、処理槽（１）内部の残渣取り出しを爪付き湾曲攪拌翼（７）の回転によって、容易に排出させる為の回転方向設定である。
【００３２】
処理機本体（１６）周囲は、難燃材又は不燃材による断熱材が裏側に装着された断熱材付き化粧板（２６）で囲われ、四隅の角部は船舶特有の動揺による生ごみ投入者の万一の転倒時の事を考慮して安全の為に丸みを付けているが、船舶に限らず、陸上施設に設置の場合に於ても、幼児、児童の行動を考慮したものである。
【００３３】
処理槽（１）と断熱材付き化粧板（２６）との空間には、温度制御付き加温装置（２７）が装備されており、北洋航路等の寒冷地域航海、又、極寒冷地の陸上施設に設置した場合の処理槽（１）の微生物に必要な最低の環境温度の維持を図るものであるが、この温度制御付き加温装置（２７）の温度制御機構が万一故障して温度が上昇しても、完全に安全性を保持するように、二段階に温度ヒュ−ズを設置するものである。
また、温暖地域では、温度制御機構により温度制御付き加温装置（２７）は稼働しないように構成されている。
【００３４】
処理槽（１）内の上部天井には、左側処理槽壁（２）に一端を固定された非常停止ワイヤ−（３１）の他端は、右側処理槽壁（３）を貫通して処理槽（１）の外部に設置した槽内非常停止スイッチ（３２）に接続固定されているが、処理槽（１）内の何処に居ても、万一攪拌軸（４）が微速回転した場合は手を上げて非常停止ワイヤ−（３１）を引く事により機器は全停止する。
【００３５】
このような大型生ごみ処理機の場合、処理槽（１）内部の掃除、故障修理等の為に作業員が入る事も考えられる為、処理槽（１）外部の過失等による万一の機器稼働時には、攪拌軸（４）の回転が微速である事から、内部において瞬時に非常停止ワイヤ−（３１）を引くことにより、機器の全停止を可能としたものである。
【００３６】
処理槽（１）の左側処理槽壁（２）と右側処理槽壁（３）には、夫々１個づつ、絶縁埋設設置された２個の電極（３３），（３３）があり、この２個の電極（３３），（３３）に微弱電流を通電させ、その両極板間の抵抗値によって処理槽（１）内部の状態を自動的に処理機本体（１６）外部に設けられた表示パネル（３３ａ）にメッセ−ジするものである。また、この微弱電流値によって微生物の働きをコントロ−ルする事が可能にしたものである。
【００３７】
処理機本体（１６）に設置された電気制御盤（３４）内に装填されているリレ−、タイマ−等の各電気機器配列の電気制御基板（３５）は、図３に示すように、電気基板緩衝材（３６）を挟んで固着されている。この目的は、処理機本体（１６）を船舶に搭載する場合、レシプロ低速回転エンジンにありがちな、強振動から、リレ−、タイマ−等の電気機器の誤作動を防止する為である。
【００３８】
攪拌軸（４）の左右両端と左側処理槽壁（２）、右側処理槽壁（３）の攪拌軸（４）貫通部に、攪拌軸外径と同様の内径を持つ対摩耗性シ−リング材が装着されたシ−リングハウジング（３７）が固定装着されており、攪拌軸（４）の回転によって処理槽（１）外に漏洩する粉塵から軸受ベアリング（６）を保護するものである。
【００３９】
また、処理機本体（１６）の前面に付設される破砕機（４０）は、図４に示すように、破砕機注水管（３９）を持ち、処理槽（１）と固水分離機（４３）を介して接続されている。
この破砕機（４０）に投入された生ごみは微細破砕されて、破砕生ごみ移送管（４２）によって固水分離機（４３）の円筒形固水分離多孔板（４４）で固水分離され、破砕生ごみ（４１）は、ブラシ付き螺旋翼（４７）によって処理槽（１）に圧送される。
また、固水分離機（４３）で分離された分離水は分離水排水口（４５）を経由して汚水貯留タンク（４６）に導入され、陸上施設にポンプアップされるか、場合によっては、汚水浄化装置付きの汚水貯留タンク（４６）を設置するものである。
【００４０】
上述の様に構成した本発明の微生物による生ごみ消滅機は以下のような作用を生じる。
まず、破砕機で生ごみを微細化する事によって単位重量あたりの表面面積を拡大し、分解媒体材に着床した好気性の有機物分解微生物の活性化の為、処理槽下部から新鮮な空気を処理槽内に供給し、処理槽内部の種々のガス、水蒸気は絶えず処理機外部に排出して酸化分解作用も併合し、分解媒体材は乾燥状態に保って臭気発生源の一つである雑菌の繁殖を防止し、生ごみの持つ８５％以上の水分を利用して、臭気発生の要因である人工的加温、温度上昇をさせずに、２５℃前後の常温で急速分解消滅させることにより、消臭装置を必要としないものとなる。
【００４１】
分解媒体材に使用する樹木粉に無機吸湿材を混合攪拌する事により、従来の樹木粉のみによる分解媒体材の必要量が半分で済み、処理機本体の小型化、攪拌駆動トルクの減少、ひいては稼働の低騒音化が可能となる。
分解媒体材が乾燥状態にある為冬期に於ても熱伝導率が低く放熱現象が少ない為、生ごみの分解時における発熱の放散度が少なく、超寒冷地域での使用以外は、分解媒体材自体が断熱材的役割を果たし、加熱の為のヒ−タ−の設置を要しない。
また、処理槽自体を加熱ヒ−タ−板等によって直接加熱する事は、処理機本体が鋼板製である限り放熱により非常に大きな電力のロスが発生し、発電量に限度がある船舶では、このために電気容量不足も起き得る。そのため処理槽外周を温風加熱方式によって雰囲気環境温度の上昇が図れることにある。

また、冬期北海道等の厳寒地の陸上施設での稼働、及び、海上保安庁観測船に冬期に搭載した処理機の様に、マイナス２０℃に及ぶ北洋海域での例もある事から、処理機本体の周囲は、難燃又は不燃断熱材付設の化粧板で囲っているが、この断熱材は寒冷地域のみに限らず、極暑地域においても可能な限り処理槽自体を周囲環境からの影響を防止するために装着しており、断熱材付き化粧板と処理槽との空間には温度制御付き加温装置を設置し、尚且、処理槽内への空気供給機は、必要ある場合は別途加温空気供給機とし、如何なる寒冷地域においてもその効果を発揮出来るようにしたが、この場合、安全の為に温度制御機と共に二段階の温度ヒュ−ズ設置を行った事により、万一の温度制御器、温度ヒュ−ズ不作動による火災事故の発生の危険性を低減する。
【００４３】
生ごみの分解消滅につきまとう分解水の処理は、樹木粉に混合攪拌した無機吸湿剤と分解媒体材によって吸い取られ、前述の様に発散蒸発され、生ごみ分解水は一滴も処理槽から排出されない。従って水分８５％以上を持った生ごみを投入しても、分解の過程で発生する分解水は、吸水率と自己発散性が非常に高い分解媒体材を選択使用し、処理槽内での完全攪拌と排気ファン、或は空気供給機によって蒸発し、耐えず分解媒体材を乾燥状態に保ち、分解水の処理機外への排出を完全に無くす。
【００４４】
生ごみの中には、魚の骨、卵の殻等も必然的に発生するが、魚の骨はカルシュウムと他の蛋白質等の結合によって構成されており、その蛋白質等の有機物の分解で骨、殻の形状は目視不能となり、卵の殻は、内側甘皮の分離分解、外部カルシュウム殻は魚の骨同様に分解消滅させる事としたが、鳥足唐揚の骨、骨付き牛豚肉の大骨、貝汁の貝殻等は予め破砕機を経由する事により微細化して処理機に投入される。
【００４５】
生ごみごみを破砕機によって微細な破砕生ごみにする事は、如何なる大きな牛豚の骨でも、処理槽に投入後数か月で目視不能まで消滅されるが、魚の骨類は原形のまま投入しても１日で消滅し、又卵の殻も原形でのまま投入しても数日で目視不能となることは、そのカルシュ−ムの結着構成剤である有機物を分解することによるものである。
【００４６】
生ごみの処理をする場合、生ごみと共に発酵促進剤を投入する事は、多忙な日課に於ける最も煩わしい作業の一つであり、又万一の投入忘れによる生ごみ処理不能、効果減退、或は過失による食品との混合もあり得る事から、本発明は、分解媒体材自体に分解菌を事前に着床させ、処理槽への生ごみ投入期間中に発酵促進剤類の添加投入の必要がないものとした。
【００４７】
分解媒体材に事前に有機物分解菌を着床させることによって、一定期間毎に分解促進剤を投入する煩わしさを解消したが、実験室の菌培養シャ−レ−と同様の基本概念であり、処理槽をシャ−レ−とみなし、分解媒体剤と生ごみがシャ−レ−内の菌栄養素となる。
【００４８】
処理機本体の故障の場合の大型生ごみ消滅機は、工場持ち帰り修理は非常に大きな費用を要し、特に船舶では陸上のクレ−ン使用が必須条件となる為、本発明は、処理機本体設置後は如何なる部分も、処理機本体を移動せずに部品交換によって更新可能とし、攪拌翼と攪拌軸の結合の様にクランプ方式とすることにより、例えぱ、処理槽内の酸化促進雰囲気と回転攪拌反復応力による溶接部脆性破壊脱落を回避することが可能となる。
【００４９】
攪拌機構の簡素化と分解媒体材の特質により、本発明は処理槽内の分解媒体材が軽量、通気性が非常に良い事、分解媒体剤の乾燥状態維持等による処理機の小型化、又攪拌翼は微速回転で良い事から、攪拌駆動機容量の小型化と、極寒冷地域以外は加温器不要の為めに機構的に簡素化し機器故障率の極限迄の減少をはかることができる。
【００５０】
処理槽に異物混入による攪拌翼の折損事故が発生しても、攪拌翼は攪拌軸との固着方式を溶接部無しのクランプ締めつけとし、処理機本体を移動する事なく簡単に交換可能な方式とした。
攪拌効率の向上の為、処理槽の大きさによって爪付き湾曲攪拌翼の本数は増えるが、その爪は左右の処理槽壁両端から攪拌軸の長さ中心に向かっておおよそ３０度傾斜させ、攪拌軸中心部の爪付き湾曲攪拌翼の爪は水平対称の２本設置とし、その爪の傾斜角度は、夫々攪拌軸の左右両端に向かって傾斜固着させる事により、低速回転攪拌翼による槽内分解媒体剤の攪拌効率が最良であることを確認した。
【００５１】
爪付き湾曲攪拌翼の湾曲度は、おおよそ処理槽の直径の２分の１の長さの半径湾曲度とすることにより、攪拌効率の向上と、攪拌軸の回転方向に湾曲線内側を向ける事により、攪拌駆動機のトルク減少につながる。
また、爪付き湾曲攪拌翼の湾曲度によっては、湾曲度が必要以上に大きい場合と小さい場合は、分解媒体材の攪拌効率が著しく損なわれ、又爪付き湾曲攪拌翼の爪の傾斜が小さ過ぎる場合と大き過ぎる場合も同様であり、湾曲曲線の内側に向かって回転する事によって攪拌駆動機のトルクが大きく減少されると同時に、攪拌効果も上昇する。
【００５２】
従来の微生物による生ごみ処理機は、その使用条件によって大きく効果の差が発生して使用不能な事例まで発生しており、特に使用者の交代等による引継ぎ説明不足の場合を想定し、本発明はその欠点を極限まで解消する為に、処理槽内の電気極板で、電気的センサ−により処理機使用者への正常、注意、異常、の伝達を自動的に行うと同時に、微弱電流による微生物の活性化、不活性化のコントロ−ルを試み、一定の効果を生んだ。
【００５３】
従来の微生物による生ごみ処理機の使用者は生物学的専門家でない為に、生ごみ投入量の処理能力以上の超過投入、生ごみ種類による水分率の差、水切りの悪さ、規定の継続使用期間を超過した使用、其の他諸々の原因による生ごみ分解度の低下、悪臭の発生等が発生したが、本発明は、使用者に対して処理槽内の状況を電気的に検知してランプ、又は音声によって処理機外に知らせることが可能となった。
【００５４】
本発明の処理槽内の分解媒体材は乾燥状態を保っているが、水分率がゼロではなく、微弱電流の導電作用を持っている為、生ごみの投入によってその水分率が変化する事を利用して処理槽内の分解媒体材の一定間隔の電気抵抗値を計測し、その値によって何段階にでも処理槽内の分解媒体剤の状態の良否を、音声又は表示ランプで伝達する様にした。
【００５５】
本発明の処理槽内の分解媒体材は乾燥状態にある為に、最良の状態では導電率が低いが、これが使用者によって処理能力以上の量の生ごみを続けて投入した場合や、水切り状態をおろそかにしたり、みそ汁等の液体を大量に投入した場合、規定の連続使用期間を超過して分解媒体材の交換を行わない場合、排気ファンが故障した場合、等々に起因して分解媒体材の水分率が上昇するが、水分率が上昇すれば導電率も変化して状態の把握が容易となり、事前に対応が可能となった。
【００５６】
処理機使用上の安全対策は、処理機本体前面に非常停止ボタンスイッチの設置は当然であるが、大型生ごみ消滅機の場合は、処理槽内部の掃除、攪拌軸、爪付き湾曲攪拌翼の修理等の為に処理槽内部に人が入る事があり、間違って処理機外部の者が水密投入口蓋を閉鎖して稼働ボタンを押した場合でも、処理槽内部の者が暗闇でも、又処理槽の何処に居ても、確実に操作出来る非常停止ワイヤ−を設置したので、安全性が高まる。
【００５７】
また、本発明の微生物による生ごみ消滅機による生ごみの分解消滅日数は数多くの試験結果があるが、この一覧列挙は、破砕機で処理した破砕生ごみの消滅時間である。
尚、破砕しない原形生ごみの消滅時間は、生ごみによって異なるが、表面面積の差からその処理時間はおおよそ下記時間の２００％乃至３００％増しとなる。
（ア）いわしの、頭、骨６時間消滅度は目視不能
（イ）さばの、頭、骨８時間消滅度は目視不能
（ウ）煮物野菜３時間消滅度は目視不能
（エ）生もの野菜６時間消滅度は目視不能
（オ）残飯１０時間消滅度は目視不能
（カ）みかんの皮１２時間消滅度は目視不能

【００６７】
図１１に示す実施例は、左側処理槽壁（２）と右側処理槽壁（３）に、フランジ付き耐摩耗性スリ−ブ（５１）が固着され、それを貫通して挿入設置された攪拌軸（４）の実施例であって、処理槽内部の粉塵等の処理槽（１）外部への漏洩を防止するものであり、簡単に、確実に、製造経費の削減に役立つ。
【００６８】
図１２に示す実施例は、空気供給機（２１）の吸気吸引口に空気加温器（５２）が付設された実施例であるが、寒冷地域における処理槽（１）内の温度低下を防止する為にあり、マイナス２０℃前後の極寒冷地域において処理機を使用する場合で、雰囲気温度上昇目的の処理機本体（１６）内に設置した温度制御付き加温装置（２７）の稼働に於ても温度不足の場合に、直接、処理槽（１）内に温風を供給した実施例である。

【００７２】
【発明の効果】
本発明は上述の通り、処理機としての微生物による生ごみの無臭分解消滅無排水機構と、生ごみを分解消滅させる微生物を着床した分解媒体材とに分けられるが、生ごみの分解消滅は、被分解生ごみの種類、含水度、処理容量、外気気温、外気湿度等あらゆる条件を考慮して初めて無臭分解消滅無排水が可能であり、その為には、生ごみ消滅機の機構と共に、その機構に合った最良の分解媒体材とを合致したものである。
【００７３】
本発明は、分解媒体材に加湿する事なく、生ごみの持つ水分で分解が可能である事から、非常に簡単な機構の、単なる攪拌翼の回転で万遍なく攪拌が出来る事から、生ごみの種類の差に殆ど関係なく、分解媒体剤と、処理機本体で生ごみを分解消滅できるという効果を奏する。
【００７４】
また、本発明は、微生物の分解能力にプラスして耐えず新鮮な空気の供給を行って酸化現象の促進と、分解消滅に必要以外の水分を発散させ、同時に分解媒体材自体の消臭機能をも加味し、これらの効果を発揮させる為、処理機構に於ても、微速ながら耐えず攪拌するか、或は、一定時間毎に間欠自動攪拌を行い、吸水性能並びに水分自己発散機能を持った分解媒体材とに相まって、酸素の完全な供給と水分の発散を自動的に行い、臭気発生を極限まで抑制できる。
【００７５】
また、機器の超小型を実現する為に、生ごみを破砕機によって破砕微細化した生ごみして単位重量当たりの表面積を拡大し、分解消滅速度を増進することができる。
【００７６】
また、分解媒体剤は、木粉に種々の吸湿材を配合することにより、生ごみ１Ｋｇ当たり１０リットルで済み、又先入れ先出し方式の１槽式で省スペ−スを図る事により、攪拌稼働時の電力消費も半減し、設置時の処理機台板下に設置する緩衝材との効果も相まって低騒音の稼働が可能となったものである。
【００７７】
また、環境汚染防止の観点から、生ごみ破砕機から発生する水液は、固水分離して汚水処理タンクに貯留し、陸揚げ後に処理、又は浄化機能を持った汚水処理タンクで浄化処理するができ、環境汚染防止が図ることができる。
【００７８】
生ごみの処理をする場合、生ごみと共に発酵促進剤的な物質を投入する事は、多忙な日課に於ける最も煩わしい作業の一つであり、又万一の投入忘れによる生ごみ処理不能、効果減退、或は過失による食品との混合もあり得る事から、本発明は、分解媒体材自体に分解菌を事前に着床させることにより、処理槽への生ごみ投入期間中に発酵促進剤類の添加投入の必要がなくなったので、最も煩わしい作業から解放された。
【００７９】
処理槽内の分解媒体材攪拌と生ごみとの攪拌は、水密投入口蓋を開ける事によって、駆動発停スイッチで自動的に感知して停止し、攪拌軸の稼働は水密投入口蓋の閉鎖で稼働し、仮に攪拌軸が稼働中であっても開放すると停止するので、安全性が高まった。
【００８０】
船舶特有の各種振動を吸収して機器を常に正常に稼働させる為に、電気制御盤内の電気制御基板取付に対し、緩衝材を挟んで設置し、必要に応じて処理機台板下に処理機全体の、船舶各種振動からの保護の為緩衝材の設置を行ったので、処理機全体の信頼性が向上した。
【００８１】
処理槽内の分解媒体材の攪拌は、使用態様より過湿状態に移行する徴候がある場合、人為的に攪拌時間を規定時間よりも長くして分解媒体材の水分を発散させる必要があり、この攪拌時間の変更を任意に設定可能にしたので、制御性能が向上した。
【００８２】
船舶はもちろん陸上施設においても、長期間使用しない事があるが、その場合、従来の生ごみ処理機は分解媒体材を処理槽から全量撤去しなければ大量の臭気ガスが発生する欠点があったが、本発明は電気制御盤内の電気回路において、水密投入口蓋開閉と連動して作動する駆動発停スイッチの作動を利用して、２４時間連続して水密投入口蓋の開閉が無い場合に、バイオ維持の目的で、最低量の酸素供給の為に２４時間毎に１回１５分間だけ攪拌軸の稼働をする様に自動的に切替えるので、処理能力が向上した。
【００８３】
分解媒体材の一定期間後の交換取り出しも、取り出し口に袋を掛ければ手を汚さずに全量取り出せる、じょうご付き取り出し口を設け、ワンタッチで取り出し口が開放可能とし、又自動で排出できる機構としたので取扱が簡単になった。
【００８４】
世界的に生ごみの処理がクロ−ズアップされている現在、大型船舶、小型船舶は、又陸上の施設に於ても購入可能な価格でなければならないが、本発明は部品点数の低減、機構の簡素化と、組み立て部品の僅少さによって製品に対するコストの減少が図られた。
【００８５】
海洋汚染防止の目的に於ての沿岸を航海する小型船、特に厨房を設置しているヨットの為に、左右両舷傾斜対応の、小型生ごみ消滅機の製作も可能になった。
【００８６】
従来の生ごみ処理機は、単にコスト削減により普通鋼を使用しているが、本発明は、可能な限りステンレス鋼を使用して耐用年数を長期化し、特に船舶使用の場合は処理機表面に防錆塗装を施し、海洋の過酷環境条件に合致させ、耐久性を向上させた。
【００８７】
船舶は電導体であり、電位差が大きい素材の集合体である為に、電気腐食度が多大であり、処理機台板と設置基盤金属が異なる場合は、電気絶縁素材で可能な限り絶縁し、電気腐食を防止したので耐腐食性が向上した。
【００８８】
北洋航路就航船の極寒冷地仕様、生ごみの破砕機及び固水分離機使用による牛豚骨、貝殻に至るまで処理機への投入処理と処理機の超小型化、完全消滅による残渣無排出の連続使用、ヨットを含む小型船舶から大型船舶までの機種対応、処理機の蓋を開けて生ごみを投入する以外は完全な全自動化、消臭装置無しでの無臭分解消滅、６時間乃至１２時間での急速消滅処理、これらは従来の生ごみ処理機では想定し得ない多大な効果である。

BACKGROUND OF THE INVENTION
The present invention relates to a processing machine that decomposes and extinguishes garbage using microorganisms. In particular, in order to comply with the Japan Marine Pollution Control Act based on ratification of international treaties based on the prevention of global environmental pollution, the global environment is considered. From the viewpoint of energy saving, space saving, odorless, no drainage, and disappearance, in the major areas of marine pollution prevention, not only onboard ships, but also on land equipment plays a major role in preventing river and groundwater pollution, The present invention relates to a garbage processing machine using microorganisms.
[0002]
[Prior art]
Conventionally, garbage treatment is a method that includes a storage tank, a fermenter tank, and an aged storage tank for putting raw garbage into a treatment tank and eradicating the raw garbage in stages. Since the fermentation fermenting bacteria were added, the fermentation was promoted to change to organic fertilizer, and the residue was discharged, stored, and disposed of in units of several days.
In recent years, a garbage decomposition processor called a single tank type decomposition processor has been proposed as an improvement to this system, and wood flour is loaded as a decomposition medium agent, and a fermentation accelerator is periodically added to the treatment tank. However, there is a heater that improves the decomposition processing function of garbage by installing a heater.
[0003]
However, in the above-mentioned decomposition processing machine, egg shells and fish bones that are close to inorganic waste are not decomposed at all, and in addition, the grains of leftover food cannot be decomposed, and further, odor is generated and worms are generated. At the same time, a heating heater was always installed as an indispensable condition for the fermentation decomposition in the treatment tank, and energy was consumed.
In addition, a deodorizing device is installed to generate a strong combined odor due to fermentation, but the combined odor-like garbage decomposition odor is almost impossible to deodorize, and in some cases, it is the same size as a garbage treatment machine. It was necessary to add a deodorant device.
[0004]
In addition, due to the low decomposition ability, the amount of decomposition medium required for decomposition of the garbage is extremely large, and naturally the treatment tank becomes large, and the fermentation accelerator is called daily with the garbage, In addition, there is a trouble of putting it into the treatment tank at regular intervals, and in addition, the odor increases every day, and the residue is taken out periodically due to the low degree of decomposition, and it is necessary to store the residue until the disposal of the residue.
Also, in the method of taking out the disassembled garbage, the complexity of bagging by human power is extremely high, and the larger the size, the larger the heating power capacity for subsidizing the fermentation, and the larger the equipment. In addition, in the agitation mechanism, the harsh conditions in the treatment tank are neglected, and the production is made just like a stirrer. Due to the high incidence rate and the difficulty of recovery and repair in the event of a failure, it was impossible to mount on a ship.
[0005]
[Problems to be solved by the invention]
Therefore, the problem with the conventional technology is that various types of deodorizers are attached for the generation of fermentation decomposition odors inevitably generated during the treatment of organic garbage. The fact is that the odor effect is not obtained, and it has been a problem to reduce the decomposition time to the utmost and to carry out the bromination-free treatment.
The specific problem will be described below.
[0006]
In order to decompose organic food waste, the main base material of the decomposition medium material is made of wood flour. Therefore, a large amount of decomposition medium material of 50 liters or more per 1 kg of food waste per day is required. Due to the large amount of water in the decomposition medium agent, there is a problem that the size of the processing machine is increased, and the noise and power consumption of the driving device increase due to an increase in the agitator torque due to the high water content.
[0007]
Since the raw garbage treatment is a fermentation treatment, water and temperature are required, and a heating heater is inevitably installed even in a normal state, which consumes a large amount of power. In addition, garbage decomposition water was generated, which was accompanied by the danger of environmental pollution and generation of decomposed water odor due to wastewater outside the processing machine.
[0008]
In conventional processing machines, fish bone, shellfish shells, egg shells, etc. that are mixed in garbage cannot be decomposed, and in general garbage, it takes a long time to decompose. Removal, storage, and disposal from the processing machine were essential conditions.
[0009]
There is a risk of increasing the cost of fermentation accelerators that are introduced every day or at regular intervals, and there is a risk of misuse of the fermentation accelerators. Reduction of the processing effect, etc. by forgetting to insert regularly has also occurred.
[0010]
Conventional garbage processing machines are manufactured as if they were organic fertilizer manufacturing machines, and have been generated from the environmental problems of garbage disposal over the past few years. There is no sense, and due to lack of practical experience in the ocean, the mechanism and strength have not been sufficiently studied, so the stirrer etc. frequently fails, and in the case of a processor failure, most mechanisms are due to the welded structure. Once a failure occurred, the processor body had to be brought back to the manufacturing plant for repair.
[0011]
There is no equipment safety in handling of conventional garbage disposal machines, and it is an automatic start / stop control only for garbage input, but in the case of large-scale treatment machines, cleaning, repair, etc. In the unlikely event that a person enters the treatment tank, there is a risk of equipment operation at the same time as the closing of the inlet due to negligence. The acute angle of the processing machine corner was also extremely dangerous.
[0012]
When mounted on a ship, depending on the weather conditions peculiar to the ocean and the navigation conditions peculiar to the ship, pitching (swaying back and forth), rolling (swinging left and right), water hammer (on the bow during stormy navigation) There was a problem such as abnormal occurrence, malfunction or stop of garbage disposal machine electric control equipment due to reciprocating main engine / red zone vibration (excessive vibration until main engine reaches normal rotation), etc. .
[0013]
Misrecognition of judgment due to lack of knowledge and experience of kitchen staff who actually use the garbage disposal machine, and because the judgment of over-drying and over-humidity of the disassembly media inside the treatment machine relies on visual judgment. Accidents such as odor emission and inability to disassemble occurred.
[0014]
Residues need to be discharged from the processing equipment at regular intervals, such as at intervals of several days, and problems such as residue storage and disposal are associated even when installed on land as well as ships. A conventional garbage processing machine is a processing machine that converts it into organic fertilizer when the daily processing capacity is 60 kg, and requires a floor area of 4.5 meters in width and 1.8 meters in depth. In some garbage processing machines, it is necessary to install a deodorizing tower with a diameter of 1.5 meters and a height of 2 meters to remove odors. Moreover, it was difficult to use at all for space installation.
[0015]
When the negative temperature continues every day in winter, especially in the case of ships, depending on the route, there are routes all over the earth such as the route directly below the equator or the North Sea route, so it must be fully effective in any environment. However, conventional garbage processing machines do not have a processing machine that can even cope with the climate of winter Hokkaido in Japan, and can only cope with the climate in central Honshu, especially spring and autumn. There were problems such as being unable to be decomposed due to an environment of minus 20 ° C. and generation of a great deal of odor under an environment of continuous 50 ° C.
[0016]
The present invention has been made in view of the above-mentioned conventional problems. Regarding the decomposition odor, the garbage area is crushed and refined to increase the surface area per unit weight and shorten the decomposition and extinction time to the limit. However, in the formulation of decomposition media necessary for the decomposition of organic matter, organic matter-degrading soil fungi are added and continuously decomposed without leaving any residue, and at the same time, the decomposition media material is maintained in a dry state for decomposition. The moisture required for the food is the moisture contained in the garbage, without using conventional high-temperature fermenting bacteria, and by the heat energy of the temperature-degrading microorganisms, the garbage is decomposed at room temperature without artificially increasing the temperature. An object of the present invention is to provide a garbage processing machine using microorganisms.

[0029]
The upper vertical wall at the front of the treatment tank (1) has a plurality of air inlets (1) for assisting water evaporation of the decomposition medium material (38) in the treatment tank (11) and supplying fresh air. The air in the processing tank (1) is sucked by the exhaust fan (14) installed at the upper part of the processing tank (1), and fresh air flows in from the air inlet (11) forcibly and decomposes.

The air supply to the treatment tank (1) by the air supply machine (21) is to supply fresh oxygen necessary for oxidative decomposition and extinction of garbage, to prevent garbage odor due to excessive humidity, and to treat garbage decomposition water. This is done for divergence.
[0031]
At the bottom of the front surface of the treatment tank (1), a take-out port (25) with a funnel that can be opened and closed with one touch is mounted.
When this take-out port (25) is attached to the lower front part of the treatment tank (1), it becomes the rotation direction of the agitation shaft (4) shown by the arrow in FIG. 1 and makes it easy to take out the residue in the treatment tank (1). However, it is also possible to install in the lower part of the rear surface of the processing tank (1), and in this case, the rotation direction of the stirring shaft (4) is reversed.

[0033]
The space between the treatment tank (1) and the decorative panel (26) with a heat insulating material is equipped with a heating device (27) with temperature control. This is intended to maintain the minimum environmental temperature required for the microorganisms in the treatment tank (1) when installed in the facility, but the temperature control mechanism of the heating device with temperature control (27) should be damaged.

[0035]
In the case of such a large garbage processing machine, it may be possible for workers to enter the processing tank (1) to clean the inside of the processing tank (1), repair the failure, etc. During operation, since the rotation of the stirring shaft (4) is very slow, the emergency stop wire (31) is instantaneously pulled inside to allow the entire stop of the device.
[0036]
On the left processing tank wall (2) and the right processing tank wall (3) of the processing tank (1), there are two electrodes (33) and (33) installed in an insulating manner, one by one.

A sealing housing (37) on which a material is mounted is fixedly mounted, and protects the bearing (6) from dust that leaks out of the processing tank (1) by the rotation of the stirring shaft (4).
[0039]
Moreover, the crusher (40) attached to the front surface of the processor main body (16) has a crusher water injection pipe (39), as shown in FIG. 4, and a processing tank (1) and a solid water separator (43). ) Is connected through.
The garbage put into the crusher (40) is finely crushed and separated into solid water by the cylindrical solid water separation perforated plate (44) of the solid water separator (43) by the crushing garbage transfer pipe (42). The crushed garbage (41) is pumped to the treatment tank (1) by the spiral blade (47) with a brush.
In addition, the separated water separated by the solid water separator (43) is introduced into the sewage storage tank (46) via the separated water discharge port (45) and pumped up to an onshore facility, or in some cases, A sewage storage tank (46) with a sewage purification device is installed.
[0040]
The garbage extinguishing machine with microorganisms of the present invention configured as described above produces the following action.
First, the surface area per unit weight is expanded by refining the garbage with a crusher, and fresh air from the lower part of the treatment tank is used to activate the aerobic organic matter-degrading microorganisms that have landed on the decomposition medium. Various gases and water vapor inside the treatment tank that are supplied to the treatment tank are continuously discharged to the outside of the treatment machine, and the oxidative decomposition action is also combined. By preventing overgrowth of food, using 85% or more of moisture in garbage, and rapidly decomposing and extinguishing at room temperature around 25 ° C without causing artificial warming and temperature rise, which are the causes of odor generation This eliminates the need for a deodorizing device.
[0041]
By mixing and agitating the inorganic hygroscopic material with the wood powder used for the decomposition medium material, the amount of decomposition medium material required by conventional tree powder alone can be halved, reducing the size of the processing machine body, reducing the stirring drive torque, and eventually Operation noise can be reduced.
Since the decomposition medium material is in a dry state, the thermal conductivity is low and the heat dissipation phenomenon is small even in winter, so the heat dissipation is low when the garbage is decomposed, and the decomposition medium material is used except in extremely cold areas. As such, it plays a role of a heat insulating material and does not require a heater for heating.
In addition, heating the treatment tank itself directly with a heating heater plate or the like means that as long as the main body of the treatment machine is made of steel plate, a very large power loss occurs due to heat dissipation, and in ships where the power generation amount is limited, For this reason, a shortage of electric capacity may occur. For this reason, the ambient temperature can be increased on the outer periphery of the processing tank by a hot air heating method.
[0042]
In addition, there are examples in the northern sea area that reaches minus 20 degrees Celsius, such as the operation in winter facilities such as Hokkaido in winter, and the processing equipment installed in the Japan Coast Guard observation ship in winter. The main body is surrounded by a decorative panel with a flame-retardant or non-combustible heat insulating material, but this heat insulating material is not limited to cold areas, but treats the treatment tank itself from the surrounding environment as much as possible even in extremely hot areas. A heating device with temperature control is installed in the space between the decorative veneer with insulation and the treatment tank, and an air supply machine to the treatment tank is added separately if necessary. The hot air supply machine can be used in any cold area, but in this case, the temperature controller should be equipped with a two-stage temperature fuse for safety. The occurrence of a fire accident due to the controller or temperature fuse not operating. To reduce the insurance properties.
[0043]
The treatment of cracked water for the decomposition and extinction of garbage is sucked up by the inorganic moisture absorbent and the decomposition medium mixed and stirred in the wood flour, diverges and evaporates as described above, and no drop of garbage decomposed water is discharged from the treatment tank. . Therefore, even if garbage with a moisture content of 85% or more is input, the decomposition water generated during the decomposition process is selected and used as a decomposition medium material that has a very high water absorption rate and self-divergence. It evaporates by stirring and an exhaust fan or an air supply device, keeps the decomposition medium material in a dry state, and completely eliminates the discharge of decomposition water to the outside of the processing machine.
[0044]
In the garbage, fish bones, egg shells, etc. are inevitably generated, but fish bones are composed of a combination of calcium and other proteins, and bones, shells are decomposed by decomposition of organic substances such as proteins. The shape of the shell became invisible, and the egg shell was separated and disassembled from the inner cuticle, and the outer calcium shell was disassembled and dissimilar to the fish bone. The shells of soup and the like are refined in advance by way of a crusher and then put into a processing machine.
[0045]
Making raw garbage into finely crushed garbage with a crusher means that any large bovine pig bone disappears until it is invisible within a few months after being put into the treatment tank, but the fish bones are put in their original form. However, it disappears in one day, and even if the egg shell is put in its original form, it becomes invisible in a few days due to the decomposition of the organic matter that is the binding component of the calcium. is there.
[0046]
When treating food waste, adding a fermentation accelerator together with food waste is one of the most annoying tasks in busy daily routines. In addition, since there is a possibility of mixing with food by negligence, in the present invention, the decomposition medium material itself is preliminarily implanted with decomposition bacteria, and fermentation accelerators are added to the treatment tank during the period of garbage input. It was not necessary.
[0047]
Although the troublesomeness of introducing a decomposition accelerator every fixed period was eliminated by implanting organic matter-degrading bacteria in advance on the decomposition medium material, it is the same basic concept as the laboratory cell culture laboratory in the laboratory, The treatment tank is regarded as a dish, and the decomposition medium agent and garbage become fungal nutrients in the dish.
[0048]
The large-sized garbage extinguishing machine in the case of a failure of the processing machine main body requires a very large cost for factory take-out repairs. After installation, any part can be renewed by exchanging parts without moving the main body of the processor, and by using a clamp system like the combination of a stirring blade and a stirring shaft, for example, an oxidation promoting atmosphere in the processing tank It becomes possible to avoid the brittle fracture dropout of the weld due to repeated rotational stirring stress.
[0049]
Due to the simplification of the stirring mechanism and the characteristics of the decomposition medium material, the present invention is such that the decomposition medium material in the treatment tank is lightweight and has very good air permeability, downsizing the processing machine by maintaining the dry state of the decomposition medium agent, Since the stirring blades can be rotated at a very low speed, the capacity of the stirrer drive can be reduced, and it can be mechanically simplified to reduce the equipment failure rate to the limit because it does not require a heater except in extremely cold regions. .
[0050]
Even if a stirrer blade breakage accident occurs due to foreign matter in the processing tank, the stirrer blade can be easily replaced without moving the main body of the processing machine by fixing the stirrer shaft to the clamp without a weld. did.
In order to improve the stirring efficiency, the number of curved stirring blades with claws increases depending on the size of the treatment tank, but the claws are inclined approximately 30 degrees from both ends of the left and right treatment tank walls toward the center of the length of the stirring shaft. The claw of the curved stirring blade with a claw at the center of the shaft is installed horizontally symmetrical, and the inclination angle of the claw is inclined and fixed toward the left and right ends of the stirring shaft, respectively. It was confirmed that the stirring efficiency of the medium was the best.
[0051]
The degree of curvature of the curved stirring blades with claws is set to a radius curvature that is approximately half the diameter of the treatment tank, so that the stirring efficiency is improved and the inner side of the curve line is directed in the direction of rotation of the stirring shaft. This leads to a reduction in the torque of the stirring drive.
In addition, depending on the degree of curvature of the clawed curved stirring blade, when the degree of curvature is larger or smaller than necessary, the stirring efficiency of the decomposition medium material is significantly impaired, and the inclination of the claw of the curved stirring blade with the claw is too small. The same applies to the case and the case where it is too large. By rotating toward the inner side of the curved curve, the torque of the stirring drive device is greatly reduced, and at the same time, the stirring effect is increased.
[0052]
The conventional garbage processing machine with microorganisms has occurred even in cases where it cannot be used due to a large difference in effect depending on the use conditions, especially assuming the case of lack of takeover explanation due to change of user etc. In order to eliminate the drawbacks to the limit, the electrical electrode plate in the treatment tank automatically transmits normality, caution, and abnormality to the processing machine user by means of an electrical sensor, and at the same time by a weak current. Attempts were made to control the activation and deactivation of microorganisms and produced a certain effect.
[0053]
Because users of conventional garbage processing machines using microorganisms are not biological specialists, they exceed the processing capacity of the amount of garbage input, the difference in moisture content depending on the type of garbage, poor draining, and continuous use of regulations. Use exceeding the period, degradation of garbage decomposition due to various other causes, generation of malodor, etc. occurred, but the present invention electrically detects the situation in the treatment tank for the user. It has become possible to notify the outside of the processor by a lamp or voice.
[0054]
Although the decomposition medium material in the treatment tank of the present invention is kept in a dry state, the moisture content is not zero and has a weak current conductive action, so that the moisture content changes with the introduction of garbage. By measuring the electrical resistance value of the decomposition medium material in the treatment tank at regular intervals using it, the quality of the condition of the decomposition medium agent in the treatment tank can be transmitted by sound or display lamp at any stage depending on the value. did.
[0055]
Since the decomposition medium material in the treatment tank of the present invention is in a dry state, the electrical conductivity is low in the best condition, but when this is continuously thrown in by the user in an amount exceeding the processing capacity, or in a drained state If a large amount of liquid such as miso soup is thrown in or a large amount of liquid such as miso soup is used, the decomposition medium material will not be replaced after the specified continuous use period, the exhaust fan will fail, etc. However, the electrical conductivity changes as the moisture content increases, making it easier to grasp the state and making it possible to respond in advance.
[0056]
As a safety measure for using the treatment machine, it is natural to install an emergency stop button switch on the front of the treatment machine body, but in the case of a large garbage extinguishing machine, cleaning the inside of the treatment tank, stirring shaft, curved stirring blade with claw Even if a person outside the processing machine accidentally closes the watertight inlet lid and presses the operation button, the person inside the processing tank may be treated in the dark or in the dark. Since the emergency stop wire that can be operated reliably is installed wherever it is in the tank, safety is enhanced.
[0057]
Moreover, although there are many test results for the number of days of decomposition and extinction of garbage by the garbage extinguisher by the microorganisms of the present invention, this list is the extinction time of the shredded garbage treated by the crusher.
In addition, although the extinction time of the original garbage which is not crushed differs depending on the garbage, the treatment time is approximately 200% to 300% longer than the following time due to the difference in surface area.

This is an embodiment for eliminating the burden of taking the garbage to the main body (16) of the installation. In this case, if the crushing garbage transfer pipe (42 ″) is necessary for a long time, the crushing machine can -Then was used and transported with water during crushing.
[0063]
In the embodiment shown in FIG. 7, the agitation shaft (4) is not divided into a single one, but is divided, and both ends are connected by left and right agitation shaft flanges (48). However, when light weight is required, it is used as a tube shaft, and the total weight of the processor main body (16) can be reduced, and in the event of a shaft system failure, it is possible to easily carry out and repair from the garbage input opening (28) It is a thing.
[0064]
The embodiment shown in FIG. 8 has a round stirring bar (4), a curved stirring blade (7) with claws, a stirring blade mounting portion (9) with a detent key, and a stirring blade mounting portion (10). Thus, when the stirring shaft (4) is mounted and the curved stirring blade (7) with claws is bent for some reason, it can be easily removed and restored.
[0065]
The embodiment shown in FIG. 9 uses a polygonal cross-section shaft as the stirring shaft (4), holds and holds the holding portions of the stirring bearing (6) at both ends of the shaft, This is an example of a method in which the stirring shaft (4) is inserted into the polygonal stirring shaft insertion hole (49) and is completely positioned and fixed by a bolt, and the cross-sectional type of the polygon shaft was experimentally performed with a quadrilateral, pentagonal or hexagonal shape. However, in order to reduce the manufacturing cost, the quadrangle shown in FIG. 9 is adopted, which makes it possible to reduce the machining part of the stirring shaft (4) and to cast the curved stirring blade (7) with claws.
[0066]
The embodiment shown in FIG. 10 uses a polygonal cross-section shaft as the stirring shaft (4), holds and holds the holding portions of the bearings (6) at both ends of the shaft, and has a number of curved stirring blades (7) with claws. In this embodiment, the square stirring shaft insertion hole (49) has a split stirring shaft fixing portion (50) shape and is fixed to the stirring shaft (4) by a plurality of bolts. The labor cost is reduced by reducing the lathe processing department.
[0067]
In the embodiment shown in FIG. 11, the flanged wear-resistant sleeve (51) is fixed to the left processing tank wall (2) and the right processing tank wall (3), and inserted and installed therethrough. This is an embodiment of the shaft (4), which prevents the dust inside the processing tank from leaking to the outside of the processing tank (1), and helps to reduce manufacturing costs easily and reliably.

Adopted. In recent years, we have tried to prevent corrosion by installing an anti-corrosion device, but there is a possibility that cavitation corrosion may occur in the hull or propulsion unit which seems to be sacrificial corrosion in an adjacent moored ship which does not do this. As long as it is desirable to insulate from the hull, this is an embodiment in which an electrical insulation material (56) is inserted and installed between the processing machine base (18) and the deck.
[0072]
【The invention's effect】
As described above, the present invention can be divided into a odorless decomposition and elimination / drainage mechanism of garbage by microorganisms as a processing machine and a decomposition medium material on which microorganisms that decompose and extinguish garbage are deposited. It is possible to eliminate odorless decomposition and drainage only after considering all conditions such as the type of garbage to be decomposed, moisture content, treatment capacity, outside air temperature, outside air humidity, etc. It matches the best decomposition media material that matches the mechanism.
[0073]
Since the present invention can be decomposed with moisture contained in garbage without humidifying the decomposition medium material, it can be uniformly stirred by simply rotating a stirring blade with a very simple mechanism. There is an effect that the garbage can be decomposed and extinguished by the decomposition medium agent and the main body of the processor regardless of the kind of the garbage.
[0074]
In addition, the present invention provides a deodorizing function of the decomposition medium material itself by promoting the oxidation phenomenon and releasing moisture other than necessary for decomposing and extinguishing by supplying fresh air that does not endure plus the ability to decompose microorganisms. In order to exert these effects, the processing mechanism either stirs slowly but does not endure, or performs intermittent automatic stirring every fixed time, and has water absorption performance and moisture self-dispersing function. In combination with the decomposition medium material, the complete supply of oxygen and the diffusion of moisture are automatically performed, and the generation of odor can be suppressed to the limit.
[0075]
In addition, in order to realize ultra-compact equipment, it is possible to increase the surface area per unit weight by increasing the surface area per unit weight by increasing the surface area per unit weight.
[0076]
In addition, the decomposition medium agent can be 10 liters per kilogram of garbage by blending various hygroscopic materials with wood flour. Also, by reducing the space with a one-in-first-out type tank system, Power consumption has also been halved, and combined with the effect of the cushioning material installed under the processor plate at the time of installation, it has become possible to operate with low noise.
[0077]
In addition, from the viewpoint of preventing environmental pollution, the water generated from the garbage crusher is separated into solid water and stored in a sewage treatment tank. After landing, it is treated or purified by a sewage treatment tank with a purification function. And environmental pollution can be prevented.
[0078]
When processing garbage, adding fermentative substances together with food waste is one of the most troublesome tasks in a busy daily routine, and it is impossible to dispose of food waste due to forgetting to add it. Since the effect may be reduced or mixed with food due to negligence, the present invention provides a fermentation accelerator during the period of charging garbage into the treatment tank by preliminarily degrading bacteria on the decomposition medium material itself. Since there was no need to add any other ingredients, it was freed from the most troublesome work.
[0079]
The decomposition medium material in the treatment tank and garbage agitation are automatically sensed and stopped by the drive start / stop switch by opening the watertight inlet lid, and the stirring shaft is operated by closing the watertight inlet lid. However, even if the stirring shaft is in operation, it stops when it is opened, thus increasing safety.
[0080]
In order to absorb various vibrations unique to the ship and operate the equipment normally, it is installed with the buffer material sandwiched between the electric control board mounting in the electric control panel and processed under the processor base plate as necessary. The cushioning material was installed to protect the entire machine from various vibrations of the ship, so the reliability of the entire processing machine was improved.
[0081]
When there is a sign that the decomposition medium material in the treatment tank shifts to an excessively humid state from the use mode, it is necessary to artificially extend the agitation time longer than the specified time to diffuse the moisture of the decomposition medium material, Since the change of the stirring time can be arbitrarily set, the control performance is improved.
[0082]
Although it may not be used for a long time not only in ships but also on land facilities, in that case, conventional garbage processing machines have the disadvantage that a large amount of odor gas is generated unless the entire decomposition medium material is removed from the treatment tank. However, the present invention uses an operation of a drive start / stop switch that operates in conjunction with opening and closing of the watertight inlet lid in the electric circuit in the electric control panel, and when the watertight inlet lid is not opened and closed continuously for 24 hours. For the purpose of bioretention, the processing capacity was improved because the stirrer shaft was automatically switched to operate for 15 minutes once every 24 hours to supply the minimum amount of oxygen.
[0083]
A mechanism that can be removed and replaced automatically after a certain period of time by providing a funnel-equipped take-out port that can be taken out without damaging your hands by placing a bag over the take-out port. It became easy to handle.
[0084]
At present, when garbage disposal is closed up worldwide, large ships and small ships must also be able to be purchased at land facilities, but the present invention reduces the number of parts, mechanism The cost of the product has been reduced due to the simplification of the product and the small number of assembly parts.
[0085]
For small ships sailing along the coast for the purpose of preventing marine pollution, especially yachts equipped with kitchens, it has become possible to produce small garbage extinguishing machines that can handle both left and right sides.
[0086]
Conventional garbage processing machines use plain steel simply because of cost reduction, but the present invention uses stainless steel as much as possible to prolong the service life, especially when used on ships. Rust-proof coating is applied to meet the harsh environmental conditions of the ocean and improve durability.
[0087]
Since the ship is an electrical conductor and is an aggregate of materials with a large potential difference, the degree of electrical corrosion is great, and if the processing machine base plate and installation base metal are different, insulate them as much as possible with electrical insulating materials, Corrosion resistance has been improved by preventing electrical corrosion.
[0088]
Ships in service on the North Sea route are used in extremely cold regions, garbage crushers and solid water separators are used to treat beef and pork bones, shells, and so on. Continuous use, compatible with models from small ships including yachts to large ships, fully automatic except opening the lid of the processing machine and throwing in garbage, odorless decomposition and disappearance without deodorizer, 6 hours to 12 Rapid extinction processing over time, these are enormous effects that cannot be envisaged by conventional garbage processing machines.
