Description

【0001】
【発明の属する技術分野】
本発明は、微生物の力を利用して生ごみの分解処理を行う生ごみ処理装置に関するものである。
【0002】
【従来の技術】
従来から微生物を利用して有機物及び水分を含有する生ごみを環境に影響を与えない程度に分解処理(発酵)することが行われており、この処理を行う生ごみ処理装置が知られている。
この生ごみ処理装置は生ごみ処理槽内にバイオチップと称する木質細片を生ごみ処理材として充填してあり、生ごみ処理槽に設けた投入口から生ごみを生ごみ処理槽内に投入し、生ごみ処理材に生息する微生物の働きで生ごみを発酵させて分解処理するようになっている。
【0003】
【発明が解決しようとする課題】
上記生ごみ処理装置では生ごみ処理材に生息する微生物で生ごみが消化されるものの、使用頻度により生ごみ処理槽内の生ごみ処理材の嵩が僅かづつ増えて行く。そして生ごみ処理槽内の生ごみ処理材の嵩が増えると、撹拌等がスムーズに行われなく、生ごみの処理の効率が悪くなるという問題がある。
【0004】
この問題を解決するために、生ごみ処理槽に隣接するように仕切り板を介して処理材排出槽を設けると共に仕切り板の上部に生ごみ処理槽内の生ごみ処理材を処理材排出槽にオーバーフローさせる開口部を設けることで、生ごみ処理槽内の余剰の生ごみ処理材を開口部から処理材排出槽にオーバーフローさせるようにすることが考えられる。ところが、仕切り板に設ける開口部の位置が低いと、撹拌羽根の回転にて排出の必要のない生ごみ処理材までオーバーフローにて排出してしまい、生ごみ処理槽内の生ごみ処理材の量が少なくなって生ごみの処理能力が低下するという問題がある。
【0005】
本発明は叙述の点に鑑みてなされたものであって、生ごみ処理槽内の生ごみ処理材の嵩を所定量以下に保って効率のよい生ごみ処理ができ、しかも余剰の生ごみ処理材を容易に回収できてメンテナンスが容易にでき、さらに必要以上の生ごみ処理材が生ごみ処理槽から排出されるのを防止できる生ごみ処理装置を提供するにある。
【0006】
【課題を解決するための手段】
上記課題を解決するため本発明の生ごみ処理装置は、生ごみ処理槽1内に横方向に攪拌軸11を架設すると共に攪拌軸11に攪拌軸11と略直交する方向に攪拌羽根2を突設し、攪拌軸11を回転駆動することより撹拌羽根2を回転して生ごみ処理槽1内に充填した生ごみ処理材3を撹拌すると共に生ごみ処理槽1内に投入した生ごみを分解処理するようにしたものにおいて、生ごみ処理槽1に隣接するように仕切り板4を介して処理材排出槽5を設けると共に仕切り板4の上部に生ごみ処理槽1内の生ごみ処理材3を処理材排出槽5にオーバーフローさせる開口部6を設け、このオーバーフローさせる開口部6の下縁を撹拌羽根2の回転中心と同一の同心円上で且つ撹拌羽根2の回転半径より大きいところに位置させ、上記オーバーフローさせる開口部6を攪拌羽根2の回転方向に並べた複数個の開口6a,6b,6c,6dにて構成したことを特徴とする。生ごみ処理の使用頻度により生ごみ処理槽1内の生ごみ処理材3の嵩が増えても余分な生ごみ処理材3は仕切り板4の開口部6から処理材排出槽5に排出される。これにより生ごみ処理槽1内の生ごみ処理材3が所定以上に嵩が増えず、生ごみ処理材3の撹拌等がスムーズにできて効率のよい生ごみ処理ができる。またオーバーフローさせる開口部6の下縁を撹拌羽根2の回転中心と同一の同心円上で且つ撹拌羽根2の回転半径より大きいところに位置させ、オーバーフローさせる開口部6を攪拌羽根2の回転方向に並べた複数個の開口6a,6b,6c,6dにて構成したことで撹拌羽根2が回転しても必要以上の生ごみ処理材3が開口部6の開口6a,6b,6c,6d,6eから排出されることがなく、生ごみ処理槽1内に所定量の生ごみ処理材3を保持した状態で生ごみを効率よく分解処理できる。
【0007】
また水平面で攪拌軸11と直交する方向を処理材排出槽5の前後としたとき、オーバーフローさせる開口部6を後側に偏らせると共に処理材排出槽5から生ごみ処理材3を排出させる排出口7を開口部6と逆の前側に偏らせたことを特徴とすることも好ましく、また撹拌羽根2と仕切り板4との間に15〜50mmの間隔を設けたことを特徴とすることも好ましく、また撹拌羽根2が撹拌羽根2の回転により生ごみ処理材3を仕切り板4側と反対の内向きに押す内向き形状であることを特徴とすることも好ましく、さらに生ごみ処理槽1内の生ごみ処理材3の交換をした直後に撹拌羽根2の回転数が多くなるように制御する制御手段を有することを特徴とすることも好ましい。
【0008】
【発明の実施の形態】
生ごみ処理装置は図1乃至図3に示すように上方が開口したケース8に上方が開口した生ごみ処理槽1が内装してあり、この生ごみ処理槽1内には撹拌羽根2が回転自在に内装してある。この生ごみ処理槽1を一次槽として、生ごみ処理槽1の側方に生ごみ処理槽1と隣接するように二次槽としての処理材排出槽5を一体に設けてあり、生ごみ処理槽1と処理材排出槽5との間の仕切り板4の上部には生ごみ処理槽1から処理材排出槽5に生ごみ処理材3をオーバーフローさせる開口部6を設けてある。ケース8は底部の底板8a、背部の背板8b、両側に取り付けた側カバー8c、前面の上部に取り付けた前上カバー8d、前面の下部に取り付けた前下カバー8eとで形成されている。ケース8の底板8aの下面にはベース9を装着してあり、ベース9の下端を設置できるようになっている。ケース8の上面開口には開閉自在な蓋10を装着してある。
【0009】
中空パイプ状をした撹拌軸11が生ごみ処理槽1や処理材排出槽5に貫通するように挿通してあり、撹拌軸11が生ごみ処理槽1や処理材排出槽5に軸受12にて回転自在に軸支してある。この撹拌軸11には生ごみ処理槽1内で撹拌羽根2が処理材排出槽5で撹拌羽根13が撹拌軸11の軸方向に対して略直交する方向に突出するように設けてある。撹拌軸11の一端部は生ごみ処理槽1の側壁14より外側に突出しており、撹拌軸11の外側への突出部分にスプロケット15を設けてある。上記生ごみ処理槽5内の撹拌羽根2は、本例の場合、3枚であり、生ごみ処理槽1内の略中央と両側部に位置しており、また撹拌羽根2の突出方向は周方向に略120°位相がずれている。ケース8の底板8aにはモータ16が取り付けてあり、モータ16の出力軸に設けたスプロケットと撹拌軸11に設けたスプロケット15とにチェーンを掛け回してあって、モータ16を駆動することで撹拌羽根2,13を回転して生ごみ処理槽1及び処理材排出槽5内の生ごみ処理材3を撹拌するようになっている。撹拌羽根2,13の回転の制御は制御部によりされるが、この制御部はケース8の上部に設けてある。
【0010】
生ごみ処理槽1の下部の外面部には面ヒータを取着してあり、生ごみ処理槽1に装填した生ごみ処理材3の温度が低い場合に面ヒータにより加熱されるようになっている。この面ヒータは上記制御部で制御されるようになっている。また生ごみ処理槽1内には微生物が生息したバイオチップと称されるおが屑状の木質細片のような担体よりなる生ごみ処理材3を入れてある。この生ごみ処理材3としては例えば従来から公知の木質細片(例えば、特公平2−30760号公報等)が使用できる。生ごみ処理槽1内には含水率センサーが配設されており、生ごみ処理槽1内の生ごみ処理材3の含水率を測定できるようになっている。この含水率センサーで測定した含水率により、制御部にてファン18や面ヒータや撹拌軸11の運転を制御できるようになっている。またファン18を回転駆動すると、ケース8の底部から吸気された外気が吸気経路19、生ごみ処理槽1の上部の吸気口を介して生ごみ処理槽1内に吸気され、生ごみ処理槽1内から排気口20、排気経路21を介して外部に排気されるようになっている。また生ごみ処理槽1の底部に点検口22を設けてあり、この点検口22を着脱自在な点検口カバー23にて覆ってある。そしてこの点検口カバー23を外すことで定期的に全量の生ごみ処理材3を交換できるようになっている。
【0011】
処理材排出槽5の下部の外面部にも面ヒータを取着してあり、処理材排出槽5に排出した生ごみ処理材3を乾燥し得るようにしてある。処理材排出槽5の前部に前方に突出するように突出箱部24を設けてあり、突出箱部24の下面開口を排出口7としてある。この排出口7の両側にはレール縁25を設けてあり、このレール縁25に受け袋26のフランジ27をスライドして着脱自在に取り付けられるようになっている。
【0012】
上記のような生ごみ処理装置において、生ごみ処理槽1内に生ごみが投入されると、撹拌羽根2が回転して生ごみと生ごみ処理材3とが撹拌混合される。すると、生ごみ処理材3に生息する微生物の働きにより生ごみが分解処理されるものである。そしてファン18を運転して生ごみ処理槽1内に於ける生ごみ処理により発生する湿気やガス等の排気は排気経路21を経て外部に排気され、同時にファン18を運転して排気することで、吸気経路19を経て吸気口から生ごみ処理槽1内に外気が供給され、これにより新鮮な酸素が生ごみ処理材3に供給されるようになって微生物の働きを活性化するものである。これにより生ごみの分解処理が漸次行われるようになっている。上記のように生ごみ処理槽1内で生ごみの処理が行われるが、生ごみの処理に従って生ごみ処理材3の量が増える。生ごみ処理槽1内の生ごみ処理材3の量が増えると、オーバーフロー用の開口部6から余剰の生ごみ処理材3が処理材排出槽5に排出される。処理材排出槽5に排出された生ごみ処理材3は加熱されて乾燥されたり、撹拌羽根13により撹拌で破砕されたり分解されたりする。処理材排出槽5に排出されて上記処理された生ごみ処理材3が受け袋26に受けられ、受け袋26に生ごみ処理材3が溜まると、受け袋26が取り外されて廃棄される。
【0013】
本発明では上記のように生ごみ処理槽1内の生ごみ処理材3の量が増えたとき、仕切り板4に設けたオーバーフロー用の開口部6から処理材排出槽5に排出されるのであるが、このとき生ごみ処理槽1からの生ごみ処理材3の排出量が必要以上にならないようにするために次の構造を採用している。仕切り板6の上部に設ける開口部6は図5に示すように前後方向に並べた複数の開口6a,6b、6c,6dにて形成されているが、開口6a,6b,6cの下縁は、撹拌羽根2の回転中心と同一の同心円上で且つ撹拌羽根2の回転半径より大きいところに位置させてある。つまり、撹拌羽根2の回転半径よりある所定の寸法だけ大きい図5の符号Aに示す領域に位置させてある。しかして撹拌羽根2を回転駆動すると、生ごみ処理材3の上のレベルが図6(a)(b)に示すように変化するが、このとき、開口6a,6b,6c,6dの下縁より上昇する生ごみ処理材3だけがオーバーフローされて処理材排出槽3に排出される。これにより必要以上の生ごみ処理材3が生ごみ処理槽1から処理材排出槽5に排出されることがなく、生ごみ処理槽1内の生ごみ処理材3の量が少なくなることがなく、生ごみ処理槽1内での生ごみの処理が効率よく行われる。
【0014】
また本発明の場合、仕切り板4に設ける開口部6としての開口6a,6b,6c,6dは後の方に偏るように設けてある。つまり、図7(b)のように上記開口6a,6b,6c,6d以外に開口6eを設けることで、前後方向の偏りがないようにしてあると、処理材排出槽5で乾燥されないまま受け袋26に入るおそれがある。処理材排出槽5にオーバーフローした生ごみ処理材3は面ヒータ30の加熱と撹拌羽根13の回転により乾燥してから受け袋26に入る構造になっているが、上記のように開口6a,6b,6c,6d、6eが偏ることなく設けてあると、開口6eからオーバーフローした生ごみ処理材3は乾燥されることなく、受け袋26に入るおそれがある。ところが、本発明の場合、図5や図7(a)のように開口6a,6b,6c,6dだけとして後に偏らせてあるため、処理材排出槽5に排出された生ごみ処理材3は直接受け袋26に入ることがなく、処理材排出槽5にて生ごみ処理材3が十分乾燥される。
【0015】
また本発明では仕切り板4に対して撹拌羽根2は図8に示すように符号Bに示す寸法だけ離してある。この寸法Bは15〜50mmとしてある。また図9に示すように撹拌羽根2は撹拌羽根2の回転により生ごみ処理材3を仕切り板4側と反対の内向きに押す内向き形状にしてある。つまり、仕切り板4と反対側が尖った断面略V字状にしてある。このような撹拌羽根2の形状にすることで生ごみ処理槽1内の生ごみ処理材3は仕切り板4に押し付けられることなく、ひいては仕切り板4のオーバーフロー用の開口部6の目詰まりを防止できる。また仕切り板4と撹拌羽根2との間隔Bが15〜50mmであると、オーバーフロー用の開口部6から生ごみ処理材3が適量だけオーバーフローされる。図10(a)に示すようにBが15mm以下あると、撹拌羽根2の形状により仕切り板4付近の生ごみ処理材3が殆ど生ごみ処理槽1の内側に移動し、仕切り板4の開口部6からオーバーフローする生ごみ処理材3が極小になる。また図10(b)に示すようにBが50mm以上になると、撹拌羽根2より持ち上がる生ごみ処理材3は撹拌羽根2と仕切り板4との間隔が広すぎることにより、仕切り板4の開口部6まで届かないで落下し、開口部6からオーバーフローする生ごみ処理材3が極小となる。従って仕切り板4と撹拌羽根2との間隔Bを15〜50mmとすると、適量の生ごみ処理材3が開口部6からオーバーフローされる。
【0016】
また生ごみ処理槽1では月に1回程度新しい生ごみ処理材3を所定量投入するというメンテナンスを行うものであるが、生ごみ処理材3を生ごみ処理槽1に投入した直後、生ごみ処理槽1内の生ごみ処理材3の体積が一時的に増加して撹拌羽根2でかきこまれにくい状況が生じるおそれがある。そこで従来、新しい生ごみ処理材3を投入した直後2rpmの回転数で3分程度撹拌し、生ごみ処理槽1内の生ごみ処理材3内の体積が定常レベルになるまでオーバーフローさせて減少させているが、本発明では4rpmの回転数で3分程度撹拌している。これにより、生ごみ処理槽1内の生ごみ処理材3が早く定常レベルになる。
【0017】
【発明の効果】
本発明は叙述のように生ごみ処理槽内に横方向に攪拌軸を架設すると共に攪拌軸に攪拌軸と略直交する方向に攪拌羽根を突設し、攪拌軸を回転駆動することより撹拌羽根を回転して生ごみ処理槽内に充填した生ごみ処理材を撹拌すると共に生ごみ処理槽内に投入した生ごみを分解処理するようにした生ごみ処理装置において、生ごみ処理槽に隣接するように仕切り板を介して処理材排出槽を設けると共に仕切り板の上部に生ごみ処理槽内の生ごみ処理材を処理材排出槽にオーバーフローさせる開口部を設けているので、生ごみ処理の使用頻度により生ごみ処理槽内の生ごみ処理材の嵩が増えても余分な生ごみ処理材は仕切り板の開口部から処理材排出槽に排出されるものであって、生ごみ処理槽内の生ごみ処理材が所定以上に嵩が増えず、生ごみ処理材の撹拌等がスムーズにできて効率のよい生ごみ処理ができるものであり、しかもオーバーフローさせる開口部の下縁を撹拌羽根の回転中心と同一の同心円上で且つ撹拌羽根の回転半径より大きいところに位置させ、上記オーバーフローさせる開口部を攪拌羽根の回転方向に並べた複数個の開口にて構成したので、撹拌羽根が回転しても必要以上の生ごみ処理材が開口部から排出されることがなく、生ごみ処理槽内に所定量の生ごみ処理材を保持した状態で生ごみを効率よく分解処理できるものである。
【0018】
また本発明の請求項2の発明は、水平面で攪拌軸と直交する方向を処理材排出槽の前後としたとき、オーバーフローさせる開口部を後側に偏らせると共に処理材排出槽から生ごみ処理材を排出させる排出口を開口部と逆の前側に偏らせたので、オーバーフローした生ごみ処理材が直接排出口に行くのを防止できるものである。
また本発明の請求項3の発明は、撹拌羽根と仕切り板との間に15〜50mmの間隔を設けたので、一層適量の生ごみ処理材がオーバーフローするようにできるものである。
【0019】
また本発明の請求項4の発明は、撹拌羽根が撹拌羽根の回転により生ごみ処理材を仕切り板側と反対の内向きに押す内向き形状であるので、必要以上の生ごみ処理材がオーバーフローするのを防止できるものである。
さらに本発明の請求項5の発明は、生ごみ処理槽内の生ごみ処理材の交換をした直後に撹拌羽根の回転数が多くなるように制御する制御手段を有するので、生ごみ処理材交換時の回転数を早くして早く生ごみ処理の定常レベルにできるものである。

In the garbage processing apparatus as described above, when the garbage is put into the garbage treatment tank 1, the stirring blade 2 is rotated and the garbage and the garbage treatment material 3 are stirred and mixed. Then, the garbage is decomposed by the action of microorganisms that inhabit the garbage treatment material 3. Then, the fan 18 is operated and the exhaust of moisture, gas, etc. generated by the garbage treatment in the garbage treatment tank 1 is exhausted to the outside through the exhaust passage 21, and at the same time, the fan 18 is operated and exhausted. Then, outside air is supplied into the garbage treatment tank 1 from the intake port via the intake passage 19, whereby fresh oxygen is supplied to the garbage treatment material 3, thereby activating the action of microorganisms. . Thereby, the decomposition process of garbage is performed gradually. As described above, the garbage is treated in the garbage treatment tank 1, but the amount of the garbage treatment material 3 increases according to the treatment of the garbage. When the amount of the garbage treatment material 3 in the garbage treatment tank 1 is increased, the excess garbage treatment material 3 is discharged from the overflow opening 6 to the treatment material discharge tank 5. The garbage processing material 3 discharged to the processing material discharge tank 5 is heated and dried, or is crushed or decomposed by stirring by the stirring blade 13. When the garbage processing material 3 discharged into the treatment material discharge tank 5 and processed as described above is received by the receiving bag 26, and the garbage processing material 3 accumulates in the receiving bag 26, the receiving bag 26 is removed and discarded.
[0013]
In the present invention, when the amount of the garbage treatment material 3 in the garbage treatment tank 1 increases as described above, it is discharged from the overflow opening 6 provided in the partition plate 4 to the treatment material discharge tank 5. However, at this time, the following structure is adopted in order to prevent the discharge amount of the garbage treatment material 3 from the garbage treatment tank 1 from becoming more than necessary. The opening 6 provided in the upper part of the partition plate 6 is formed by a plurality of openings 6a, 6b, 6c, 6d arranged in the front-rear direction as shown in FIG. 5, but the lower edges of the openings 6a, 6b, 6c are The rotation center of the stirring blade 2 is positioned on the same concentric circle as the rotation center of the stirring blade 2 and larger than the rotation radius of the stirring blade 2. That is, it is located in the area | region shown by the code | symbol A of FIG. 5 larger by a predetermined dimension than the rotation radius of the stirring blade 2. FIG. When the stirring blade 2 is driven to rotate, the level above the garbage disposal material 3 changes as shown in FIGS. 6 (a) and 6 (b). At this time, the lower edges of the openings 6a, 6b, 6c, 6d Only the garbage treatment material 3 that rises further overflows and is discharged into the treatment material discharge tank 3. Thereby, the garbage processing material 3 more than necessary is not discharged from the garbage processing tank 1 to the processing material discharge tank 5, and the amount of the garbage processing material 3 in the garbage processing tank 1 is not reduced. The processing of garbage in the garbage processing tank 1 is performed efficiently.
[0014]
In the case of the present invention, the openings 6a, 6b, 6c and 6d as the openings 6 provided in the partition plate 4 are provided so as to be biased toward the rear. That is, as shown in FIG. 7B, if the opening 6e is provided in addition to the openings 6a, 6b, 6c and 6d so that there is no deviation in the front-rear direction, the material is received in the treatment material discharge tank 5 without being dried. There is a risk of entering the bag 26. The garbage treatment material 3 overflowing into the treatment material discharge tank 5 is structured to be dried by heating of the surface heater 30 and rotation of the stirring blade 13 and then into the receiving bag 26, but as described above, the openings 6a and 6b. , 6c, 6d, and 6e are provided without being biased, the garbage disposal material 3 overflowed from the opening 6e may enter the receiving bag 26 without being dried. However, in the case of the present invention, since only the openings 6a, 6b, 6c, 6d are biased later as shown in FIG. 5 and FIG. 7 (a), the garbage treatment material 3 discharged to the treatment material discharge tank 5 is The garbage treatment material 3 is sufficiently dried in the treatment material discharge tank 5 without entering the receiving bag 26 directly.
[0015]
Further, in the present invention, the stirring blade 2 is separated from the partition plate 4 by the dimension indicated by the symbol B as shown in FIG. This dimension B is 15-50 mm. Further, as shown in FIG. 9, the stirring blade 2 has an inward shape that pushes the garbage disposal material 3 inwardly opposite to the partition plate 4 side by the rotation of the stirring blade 2. That is, it has a substantially V-shaped cross section with a point opposite to the partition plate 4. By making the shape of such a stirring blade 2, the garbage processing material 3 in the garbage processing tank 1 is not pressed against the partition plate 4, thereby preventing clogging of the opening 6 for overflow of the partition plate 4. it can. Moreover, when the space | interval B of the partition plate 4 and the stirring blade 2 is 15-50 mm, the garbage disposal material 3 will overflow by appropriate amount from the opening part 6 for overflow. As shown in FIG. 10A, when B is 15 mm or less, the garbage treatment material 3 near the partition plate 4 moves to the inside of the garbage treatment tank 1 due to the shape of the stirring blade 2, and the opening of the partition plate 4 is opened. The garbage disposal material 3 overflowing from the part 6 is minimized. Further, as shown in FIG. 10B, when B is 50 mm or more, the garbage processing material 3 lifted from the stirring blade 2 has an opening portion of the partition plate 4 because the distance between the stirring blade 2 and the partition plate 4 is too wide. The garbage disposal material 3 that falls without reaching 6 and overflows from the opening 6 is minimized. Therefore, when the interval B between the partition plate 4 and the stirring blade 2 is 15 to 50 mm, an appropriate amount of the garbage treatment material 3 overflows from the opening 6.
[0016]
The garbage treatment tank 1 performs maintenance such that a predetermined amount of the new garbage treatment material 3 is introduced about once a month. Immediately after the garbage treatment material 3 is introduced into the garbage treatment tank 1, the garbage is disposed. There is a possibility that the volume of the garbage treatment material 3 in the treatment tank 1 temporarily increases and a situation in which it is difficult to be scraped by the stirring blade 2 may occur. Therefore, in the past, immediately after introducing the new garbage treatment material 3, it is stirred for about 3 minutes at a rotation speed of 2 rpm, and the volume in the garbage treatment material 3 in the garbage treatment tank 1 is reduced by overflow until it reaches a steady level. However, in the present invention, stirring is performed for about 3 minutes at a rotation speed of 4 rpm. Thereby, the garbage processing material 3 in the garbage processing tank 1 becomes a steady level early.
[0017]
【The invention's effect】
In the present invention, as described above, a stirring shaft is installed horizontally in the garbage treatment tank, and a stirring blade is provided on the stirring shaft in a direction substantially perpendicular to the stirring shaft, and the stirring shaft is driven to rotate. in garbage disposal apparatus that decomposing garbage charged into the garbage treatment tank while stirring the garbage treating material filled to the garbage treatment tank rotates, adjacent to garbage treatment tank In addition, a treatment material discharge tank is provided through the partition plate and an opening is provided at the top of the partition plate that allows the waste treatment material in the garbage treatment tank to overflow into the treatment material discharge tank. Even if the volume of the garbage treatment material in the garbage treatment tank increases depending on the frequency, the excess garbage treatment material is discharged from the opening of the partition plate to the treatment material discharge tank, The garbage processing material does not increase in volume more than the specified amount, The processing material can be agitated smoothly so that efficient garbage treatment can be performed, and the lower edge of the opening to be overflowed is on the same concentric circle as the rotation center of the stirring blade and from the rotation radius of the stirring blade Since the opening to be overflowed is arranged with a plurality of openings arranged in the rotation direction of the stirring blade, the waste disposal material more than necessary is discharged from the opening even if the stirring blade rotates. Thus, the garbage can be efficiently decomposed in a state where a predetermined amount of the garbage treatment material is held in the garbage treatment tank.
[0018]
Further, the invention according to claim 2 of the present invention is such that when the direction perpendicular to the stirring axis in the horizontal plane is the front and rear of the treatment material discharge tank, the overflow opening is biased to the rear side and the garbage treatment material is disposed from the treatment material discharge tank. Since the discharge port for discharging the waste is biased to the front side opposite to the opening, it is possible to prevent the overflowed garbage disposal material from going directly to the discharge port.
In the invention according to claim 3 of the present invention, since an interval of 15 to 50 mm is provided between the stirring blade and the partition plate, a more appropriate amount of the garbage treatment material can overflow.
[0019]
In the invention of claim 4 of the present invention, since the stirring blade has an inward shape that pushes the garbage processing material inwardly opposite to the partition plate side by the rotation of the stirring blade, an excessive amount of garbage processing material overflows. It can prevent it.
Furthermore, the invention of claim 5 of the present invention has a control means for controlling the rotation speed of the stirring blade to be increased immediately after replacing the garbage processing material in the garbage processing tank. The rotational speed of the hour can be increased to quickly reach the steady level of garbage disposal.
