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汚泥を環境に影響を与えない程度に分解処理(醗酵)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る。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醗酵させて分解処理するようになっている。
【0003】
生ごみ処理槽には吸気口部を設けて外気を吸気して生ごみ処理材に空気を供給するようにしている。また、生ごみ処理槽内における生ごみ処理材による生ごみの分解処理で発生したガス等の排気は生ごみ処理槽の上部に設けた排気路から排出するようになっている。そして、排気路中に臭気を含んだ気体を加熱して脱臭する脱臭装置を設けて脱臭することが行われている。
【0004】
ところが、従来にあっては、排気路の途中に設けた加熱して脱臭する脱臭装置により脱臭する際に使用された熱は回収されて再利用されるようなことなく廃棄されていた。
特に、従来にあっては、吸気口部が排気口部に近いと吸気口部から排気口部に直ぐにショートパスしてしまうので吸気口部と排気口部とを離すように設計しており、このため、排気口部の略下方位置に導出する排気路(つまり排気路の管路長を短くするために一般的に排気口部の略下方位置に排気路を導出している)に設けた脱臭装置から出る排熱を吸気口部に取り入れることができなかった。
【0005】
また、生ごみ処理材を充填した生ごみ処理槽内に生ごみを投入して分解処理するのであるが、生ごみの中には生ごみ処理材で分解処理されない未処理物が発生し、このため、生ごみ処理槽内における生ごみ処理材が増量状態となり、攪拌手段により十分に攪拌混合ができなくなるという事態になる。これに対応するものとして、生ごみ処理槽を単槽とするのではなく、生ごみ処理槽を仕切りで仕切って生ごみが投入されて生ごみの分解処理をする1次槽と、1次槽で増量した生ごみ処理材を仕切りに設けたオーバーフロー用開口部を介してオーバーフローさせて溜めるための2次槽とを設けるものがある。このものにおいては、1次槽において生ごみ処理材が増量するとオーバーフロー用開口部を介して2次槽に排出されて溜められるために1次槽内における生ごみ処理材の量を常時適量とすることができる。しかしながら、2次槽内に溜まった生ごみ処理材に対しては空気の供給等は積極的におこなっておらず、また、2次槽内に溜まった生ごみ処理材を加熱するようになっておらず、このため、2次槽に生ごみ処理材中に生ごみが含まれた状態でオーバーフローすると、2次槽内で生ごみが十分に分解処理されないままの状態で溜められたり、あるいは生ごみ処理材に多くの水分を含んだままの状態で溜められるという問題がある。
【0006】
【発明が解決しようとする課題】
本発明は上記の従来例の問題点に鑑みて発明したものであって、吸気口部から排気口部へのショートパスを防止しながら、排気口部に接続した排気路に設けた加熱により脱臭する脱臭装置から出る排熱を有効に取り込んで2次槽に加熱空気として供給できるようにし、2次槽における生ごみ処理材による生ごみの分解処理を効果的に行うことができる生ごみ処理装置を提供することを課題とするものである。
【0007】
【課題を解決するための手段】
上記課題を解決するために、本発明の生ごみ処理装置は、ケース17内に内装した生ごみ処理槽1を仕切り2で仕切って生ごみが投入されて生ごみの分解処理をする1次槽3と、1次槽3で増量した生ごみ処理材を仕切り2に設けたオーバーフロー用開口部4を介してオーバーフローさせて溜めるための2次槽5とを設け、上記生ごみ処理槽1の側壁7の上端縁に沿って内方に小間隙を介して垂下片6を設けると共に側壁7と垂下片6との間を下方が開口した通路8として該通路8を1次槽3から2次槽5に到るように連通させ、1次槽3の上部に吸気口部9と排気口部10とを設け、吸気口部9を通路8内に開口させ、排気口部10に通路8と排気口部10とを遮断するための遮断部11を設け、排気口部に接続した排気路を生ごみ処理槽1の側壁と、これと対向するケース17の側壁との間に配置し、該排気路12中に生ごみ処理槽1から発生する臭気を含んだ気体を加熱して脱臭する脱臭装置13を設け、脱臭装置13のほぼ上方位置に吸気口部9を配置して成ることを特徴とするものである。このような構成とすることで、生ごみ処理槽1内における生ごみの分解処理により発生した湿気や臭気を含む排気は排気口部10から排気路12を経て外部に排出されるのであるが、この際、排気路12の途中に設けた脱臭装置13により加熱して脱臭される。この加熱脱臭の排熱により加熱された脱臭装置13の周囲の空気が上昇し、脱臭装置13の略上方に位置する吸気口部9から生ごみ処理槽1の上部に設けた通路8に流れ込む。通路8に流れ込んだ加熱された空気は高温となっているので通路8の上部を2次槽5側に向けて流れて2次槽5内に流れ込み、このように2次槽5内に加熱された空気が供給され、更に、2次槽5から仕切り2に設けたオーバーフロー用開口部4等を介して1次槽3に流れて1次槽3にも加熱された空気が供給されることになる。ここで、排気口部10に通路8と排気口部10とを遮断するための遮断部11を設けてあることで、通路8内に流れ込んだ加熱された空気が通路8から排気口部10にショートパスすることがなく、これにより排気口部10と吸気口部9とを近づけても問題がないものである。
【0008】
また、通路8の天井部14を1次槽3側から2次槽5側にかけて上り勾配となるように傾斜させることが好ましい。このような構成とすることで、吸気口部9から通路8に流れ込んで加熱された空気がスムーズに2次槽5側に流れることになる。
また、脱臭装置13の上方に生ごみ処理槽1の吸気口部9に熱気をガイドして導入するためのガイド板15を設けることが好ましい。このような構成とすることで、脱臭装置13の排熱で加熱された空気をガイド板15でスムーズにガイドして吸気口部9から通路8内に流入させることができるものである。
【0009】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
図1、図2に示すように、生ごみ処置装置16はケース17内に生ごみ処理槽1を内装し、ケース17の上開口部に開閉自在な蓋18を取付けて構成してある。生ごみ処理槽1は1次槽3と2次槽5とに分けてあり、1次槽3と2次槽5とは仕切り2により仕切ってある。1次槽3は生ごみが投入されて生ごみの分解処理をするための槽であり、2次槽5は1次槽3で増量した生ごみ処理材30を仕切り2に設けたオーバーフロー用開口部4を介してオーバーフローさせて溜めるための槽である。生ごみ処理槽1には攪拌手段19が設けてある。攪拌手段19は回転軸20に複数の攪拌突出部21を突出して構成してあり、攪拌突出部21は1次槽3内だけでなく2次槽5内にも設けてある。回転軸20はモータ(図示せず)により回転されるものである。
【0010】
1次槽3内には所定のレベルまで生ごみ処理材30が充填してある。生ごみ処理材30は微生物が棲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もので、従来から公知の木質細片が使用できるものである。
1次槽3と2次槽5とよりなる生ごみ処理槽1の側壁7の上端縁に沿って図4に示すように内方に小間隙を介して垂下片6が設けてあって、側壁7と垂下片6との間を下方が開口した通路8としてある。この通路8は1次槽3の上縁部から2次槽5の上縁部に到るように連通させてあり、1次槽3部分の垂下片6に供給用開口22が設けてある。
【0011】
1次槽3の一側壁7の上部には吸気口部9と排気口部10とが設けてある。ここで、吸気口部9は通路8内に開口している。また、図2、図3に示すように通路8の供給用開口22よりも吸気口部9と反対側に通路8を遮蔽するための遮蔽板23が設けてある。
図2に示すように、排気口部10は通路8内に開口しないように遮断するための遮断部11が設けてある。この排気口部10には排気路12が接続してあり、図1、図2に示すように、生ごみ処理槽1の排気路12は排気口部10と吸気口部9とを設けた一側壁7と、これに対向するケース17の一側壁との間に配置してあり、このようにすることで、排気路12の管路長を短くして管路抵抗を少なくするようにしてある。つまり、排気口部10を設けた面と異なる面に到るように排気路12を延出すると排気路12の管路長が長くなって管路抵抗が増して好ましくない。排気路12には排気ファン装置29が設けてあり、この排気路12の途中には生ごみ処理槽1から発生する臭気を含んだ気体を加熱して脱臭する脱臭装置13が設けてある。
【0012】
脱臭装置13は、内部の上部にヒータ(図示せず)が配置してあり、ヒータの下方に触媒(図示せず)が設けてある。この触媒はセラミックによりハニカム体を形成し、このハニカム体の表面に触媒となる白金を蒸着して構成したものである。つまり、ヒータにより加熱された臭気を含む気体が上記ハニカム体を通過する際に、白金よりなる加熱された触媒により触媒脱臭されるものである。
【0013】
排気路12の脱臭装置13よりも下流側に希釈ブロック24が設けてあり、排気路12の脱臭装置13と希釈ブロック24との間が放熱ダクト部25となっている。希釈ブロック24は上記脱臭装置13、放熱ダクト部25を経て流入した排気に外部から取り入れた外気を混入して上記排気を希釈するための装置で、この希釈ブロック24で希釈した後に排出口部26から外部に排出するようになっている。
【0014】
ここで、吸気口部9は放熱ダクト部25の略上方位置に配置してある。
しかして、上記のような構成の生ごみ処理装置16において、蓋18を開いて1次槽3内に生ごみを投入すると、1次槽3内に充填してある生ごみ処理材30により生ごみが分解処理される。この場合、攪拌手段19を回転することで生ごみが生ごみ処理材30により分解処理される。
【0015】
ところで、生ごみの組成は一般に水分が約80%、可燃分が約17%、灰分が約3%であり、上記のような微生物分解型の生ごみ処理機で処理する場合、水分は蒸発され、可燃分の60%〜90%が分解されるものであるが、難分解性の可燃分と、灰分は残さとなって生ごみ処理槽内に蓄積されていって、この残さの増加により1次槽3内の残さを含む生ごみ処理材30が増量することになる。この増量した残さを含む生ごみ処理材30の増量分は仕切りに設けたオーバーロー用開口部4から2次槽5内に排出されて2次槽5内に溜められ、一定量溜まると、オーバフローにより、又は手で排出容器や袋に排出するようになっている。そして、2次槽5内においても、攪拌手段19の回転により2次槽5内に溜められている生ごみ処理材30が攪拌混合され、オーバーロー用開口部4から生ごみ処理材30と共に生ごみが排出されても、2次槽5内においても分解処理がなされるようになっている。
【0016】
生ごみ処理槽1内において生ごみ処理材30で生ごみの分解処理を行うと、生ごみの分解処理により湿気、ガス等が発生し、これらは排気となって排気口部10から排気路12に排出される。排気路12に排出された排気は、脱臭装置13により加熱されて脱臭され、その後、希釈ブロック24で外気と混合されて希釈された後に外部に排出される。
【0017】
ここで、脱臭装置13で加熱脱臭した際の排熱が脱臭装置13や放熱ダクト部25部分で放熱される。脱臭装置13や放熱ダクト部25の周囲の空気は脱臭装置13や放熱ダクト部25からの放熱により加熱され、加熱空気が上方に上昇する。すると、前述のように、放熱ダクト部25の略上方位置に吸気口部9が配置してあるので、加熱空気が図2、図3において矢印イで示すように吸気口部9から生ごみ処理装置1の上端縁部に形成した通路8内に流れ込み、通路8内の上部を1次槽3側から2次槽5側に向けて矢印ロで示すように流れ、2次槽5の垂下片6に設けた供給用開口22から添付図面において矢印ハで示すように2次槽5内に流入する。この場合、通路8の供給用開口22の先の部分に遮蔽板23が設けてあるので、加熱空気がそれ以上先に進むことなく供給用開口22からスムーズに2次槽5内に流入されることになる。上記のように加熱空気が流れるのであるが、前述のように排気口部10は通路8内に開口しないように遮断するための遮断部11が設けてあるので、吸気口部9と排気口部10とを近づけて配置した(例えば添付図面に示すように生ごみ処理槽1の側壁の同一面に吸気口部9と排気口部10とを配置した)ものであっても、通路8内に流れ込んだ加熱空気が排気口部9にショートパスすることがないものである。
【0018】
上記のようにして2次槽5内に流れ込んだ加熱空気は攪拌手段19の回転により攪拌されている2次槽5内に溜められている生ごみ処理材30を加熱して乾燥すると共に、新鮮な空気を供給することになって、2次槽5内における生ごみ処理材30に棲息する微生物を活性化させて生ごみ処理能力を向上させ、仮に生ごみが生ごみ処理材30と共に2次槽5内にオーバーフローしても2次槽5内において効果的に分解処理するものである。2次槽5に供給された加熱空気は仕切り2に設けたオーバーフロー用開口部4を経て添付図面において矢印ニに示すように1次槽3内に供給され、1次槽3内に充填している生ごみ処理材30を加熱すると共に、新鮮な空気を供給することになって、1次槽3内における生ごみ処理材30に棲息する微生物を活性化させて生ごみ処理能力を向上させるものである。このように、2次槽3、1次槽5に脱臭装置13で加熱脱臭した際の排熱で加熱された加熱空気を順次供給して生ごみの分解処理を効果的に行うものである。
【0019】
そして、生ごみ処理槽1内において発生した排気は前述のようにして添付図面の矢印ホに示すように排気口部10から排気路12に排出されるのである。
なお、添付図面に示す実施形態においては仕切り2の上端部を切欠してオーバーフロー用開口部4を設けた例を示したが、仕切り2の上端部を生ごみ処理槽1の上端部よりも低くすることで、仕切り2の上方空間部をオーバーフロー用開口部4としてもよく、あるいは、仕切り2に孔を形成してオーバーフロー用開口部4としてもよい。
【0020】
ここで、図5に示すように、通路8の天井部14を1次槽3側から2次槽5側にかけて上り勾配となるように傾斜させると、吸気口部9から通路8に流れ込んで加熱された空気がスムーズに2次槽5側に流れ、よりいっそう通路8内に流れ込んだ加熱空気が排気口部9にショートパスすることなく2次槽5側にスムーズに流れることになる。
【0021】
また、添付図面に示すように、脱臭装置13の上方に生ごみ処理槽1の吸気口部9に熱気をガイドして導入するための傾斜したガイド板15を設けておくと、脱臭装置13や放熱ダクト部25の周囲の空気が脱臭装置13や放熱ダクト部25からの放熱により加熱されて上昇するが、この上昇した加熱空気を傾斜したガイド板15により集めながら吸気口部9にスムーズにガイドできるので、脱臭装置13や放熱ダクト部25からの排熱で加熱された加熱空気を効果的に集めて吸気口部9に供給できるのである。
【0022】
【発明の効果】
本発明の請求項1記載の発明にあっては、上述のように、ケース内に内装した生ごみ処理槽を仕切りで仕切って生ごみが投入されて生ごみの分解処理をする1次槽と、1次槽で増量した生ごみ処理材を仕切りに設けたオーバーフロー用開口部を介してオーバーフローさせて溜めるための2次槽とを設け、上記生ごみ処理槽の側壁の上端縁に沿って内方に小間隙を介して垂下片を設けると共に側壁と垂下片との間を下方が開口した通路として該通路を1次槽から2次槽に到るように連通させ、1次槽の上部に吸気口部と排気口部とを設け、吸気口部を通路内に開口させ、排気口部に接続した排気路を生ごみ処理槽の側壁と、これと対向するケースの側壁との間に配置し、該排気路中に生ごみ処理槽から発生する臭気を含んだ気体を加熱して脱臭する脱臭装置を設け、脱臭装置のほぼ上方位置に吸気口部を配置してあるので、脱臭する脱臭装置から出る排熱を吸気口部から通路内に取り込んで通路を介して2次槽に加熱空気として供給して、2次槽における生ごみ処理材を乾燥すると共に、仮に2次槽に生ごみがオーバーフローしても2次槽内においても生ごみの分解処理を効果的に行い、その後加熱空気をオーバーフロー用開口部から1次槽に送って1次槽内における生ごみ処理材による生ごみの分解処理を効果的に行うことができて、脱臭装置の排熱を有効に1次槽、2次槽に供給できるものであり、しかも、排気口部に通路と排気口部とを遮断するための遮断部を設けてあるので、吸気口部から通路内に供給した加熱空気が排気口部にショートパスするのが防止されるものである。
【0023】
また、請求項2記載の発明にあっては、上記請求項1記載の発明の効果に加えて、通路の天井部を1次槽側から2次槽側にかけて上り勾配となるように傾斜させてあるので、吸気口部から通路に流れ込んで加熱された空気がスムーズに2次槽側に流れ、この結果、排熱を利用した加熱空気を通路を通じて確実に2次槽に供給できるものである。
【0024】
また、請求項3記載の発明にあっては、上記請求項1記載の発明の効果に加えて、脱臭装置の上方に生ごみ処理槽の吸気口部に熱気をガイドして導入するためのガイド板を設けてあるので、脱臭装置の排熱で加熱された空気をガイド板でスムーズにガイドして吸気口部から通路内に流入させることができるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a garbage processing apparatus that performs a decomposition process of garbage using the power of microorganisms.
[0002]
[Prior art]
Conventionally, decomposition treatment (fermentation) of sludge containing organic matter and moisture using microorganisms is performed to such an extent that it does not affect the environment, and a garbage treatment apparatus that performs this treatment is known.
In this garbage disposal apparatus, a wood chip called a biochip is filled as a garbage disposal material in a garbage disposal tank. Garbage is thrown into the garbage processing tank through an inlet provided in the garbage processing tank, and the garbage is fermented and decomposed by the action of microorganisms that inhabit the garbage processing material.
[0003]
The garbage treatment tank is provided with an intake port so that outside air is sucked and air is supplied to the garbage treatment material. In addition, the exhaust gas such as gas generated by the decomposition process of the garbage by the garbage treatment material in the garbage treatment tank is discharged from an exhaust passage provided in the upper part of the garbage treatment tank. And deodorizing is performed by providing a deodorizing device for heating and deodorizing gas containing odor in the exhaust passage.
[0004]
However, in the past, heat used for deodorization by a deodorizing device that deodorizes by heating provided in the middle of the exhaust path has been recovered and discarded without being reused.
In particular, in the past, when the intake port portion is close to the exhaust port portion, a short path immediately passes from the intake port portion to the exhaust port portion, so the intake port portion and the exhaust port portion are designed to be separated, For this reason, it is provided in an exhaust passage leading to a position substantially below the exhaust port (that is, an exhaust passage is generally led to a position substantially below the exhaust port in order to shorten the duct length of the exhaust passage). The exhaust heat from the deodorizing device could not be taken into the intake port.
[0005]
In addition, garbage is thrown into the garbage treatment tank filled with garbage treatment material and decomposed. However, untreated materials that are not decomposed by the garbage treatment material are generated in the garbage. For this reason, the amount of the garbage treatment material in the garbage treatment tank becomes an increased state, and it becomes impossible to sufficiently perform the stirring and mixing by the stirring means. Corresponding to this, instead of making the garbage processing tank a single tank, a primary tank that separates the garbage processing tank with a partition and throws the garbage into the decomposition process of the garbage, and the primary tank And a secondary tank for overflowing and storing the garbage treatment material increased in step 1 through an overflow opening provided in the partition. In this case, when the amount of the garbage treatment material is increased in the primary tank, it is discharged and stored in the secondary tank through the opening for overflow, so that the amount of the garbage treatment material in the primary tank is always an appropriate amount. be able to. However, air is not actively supplied to the garbage treatment material collected in the secondary tank, and the garbage treatment material collected in the secondary tank is heated. Therefore, if the secondary tank overflows with the garbage contained in the garbage treatment material, the garbage is stored in the secondary tank without being fully decomposed, or There is a problem that the waste treatment material can be stored in a state of containing a large amount of moisture.
[0006]
[Problems to be solved by the invention]
The present invention was invented in view of the problems of the conventional example described above, and deodorized by heating provided in an exhaust passage connected to the exhaust port while preventing a short path from the intake port to the exhaust port. Which effectively takes in the exhaust heat coming out from the deodorizing device and supplies it to the secondary tank as heated air, and can effectively decompose the garbage in the secondary tank with the garbage treatment material. It is a problem to provide.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the garbage processing apparatus of the present invention is a primary tank in which the garbage processing tank 1 housed in the case 17 is partitioned by a partition 2 and the garbage is thrown in to decompose the garbage. 3 and a secondary tank 5 for overflowing and storing the garbage processing material increased in the primary tank 3 through the overflow opening 4 provided in the partition 2, and the side wall of the garbage processing tank 1. A hanging piece 6 is provided inward along the upper edge of 7 through a small gap, and the passage 8 is opened from the primary tank 3 to the secondary tank as a passage 8 having a downward opening between the side wall 7 and the hanging piece 6. 5, the intake port 9 and the exhaust port 10 are provided in the upper part of the primary tank 3, the intake port 9 is opened in the passage 8, and the passage 8 and the exhaust are provided in the exhaust port 10. A shut-off part 11 for shutting off the mouth part 10 is provided, and an exhaust path connected to the exhaust port part is provided as a garbage treatment tank. 1 is disposed between the side wall of 1 and the side wall of the case 17 facing this, and a deodorizing device 13 is provided in the exhaust passage 12 for heating and deodorizing gas containing odor generated from the garbage treatment tank 1. The intake port portion 9 is disposed substantially above the deodorizing device 13. By adopting such a configuration, the exhaust gas containing moisture and odor generated by the garbage decomposition process in the garbage treatment tank 1 is discharged from the exhaust port portion 10 through the exhaust passage 12 to the outside. At this time, the deodorizing apparatus 13 provided in the middle of the exhaust passage 12 is heated and deodorized. The air around the deodorizing device 13 heated by the exhaust heat of this heat deodorization rises and flows into the passage 8 provided at the upper part of the garbage treatment tank 1 from the intake port portion 9 located substantially above the deodorizing device 13. Since the heated air flowing into the passage 8 is at a high temperature, the upper portion of the passage 8 flows toward the secondary tank 5 and flows into the secondary tank 5, and is thus heated into the secondary tank 5. Air is supplied to the primary tank 3 from the secondary tank 5 through the overflow opening 4 provided in the partition 2 and the heated air is supplied to the primary tank 3. Become. Here, since the exhaust port portion 10 is provided with the blocking portion 11 for blocking the passage 8 and the exhaust port portion 10, the heated air that has flowed into the passage 8 enters the exhaust port portion 10 from the passage 8. There is no short-path, and there is no problem even if the exhaust port 10 and the intake port 9 are brought close to each other.
[0008]
Moreover, it is preferable to incline the ceiling part 14 of the channel | path 8 so that it may become an upward slope from the primary tank 3 side to the secondary tank 5 side. By setting it as such a structure, the air which flowed into the channel | path 8 from the inlet port part 9 and was heated flows smoothly to the secondary tank 5 side.
Moreover, it is preferable to provide the guide plate 15 for guiding and introducing hot air into the intake port 9 of the garbage treatment tank 1 above the deodorizing device 13. With such a configuration, the air heated by the exhaust heat of the deodorizing device 13 can be smoothly guided by the guide plate 15 and allowed to flow into the passage 8 from the air inlet 9.
[0009]

Here, the air inlet 9 is disposed substantially above the heat radiating duct 25.
Thus, in the garbage processing apparatus 16 having the above-described configuration, when the lid 18 is opened and the garbage is put into the primary tank 3, the garbage processing material 30 filled in the primary tank 3 generates the garbage. Garbage is disassembled. In this case, the garbage is decomposed by the garbage treatment material 30 by rotating the stirring means 19.
[0015]
By the way, the composition of garbage is generally about 80% moisture, about 17% combustible, and about 3% ash. When treated with the above-described microbial decomposition type garbage treatment machine, the moisture is evaporated. Although 60% to 90% of combustible components are decomposed, the incombustible combustible components and the ash components are accumulated in the garbage treatment tank as residues, and the increase in the residues causes 1 The garbage processing material 30 including the residue in the next tank 3 will increase. The increased amount of the garbage processing material 30 including the increased residue is discharged into the secondary tank 5 from the overlow opening 4 provided in the partition and stored in the secondary tank 5, and when a certain amount is accumulated, overflow occurs. By or by hand, it is discharged into a discharge container or bag. In the secondary tank 5, the garbage treatment material 30 stored in the secondary tank 5 is agitated and mixed by the rotation of the stirring means 19, and the raw garbage treatment material 30 is mixed with the garbage treatment material 30 from the opening 4 for overflow.

To be discharged. The exhaust discharged to the exhaust passage 12 is heated and deodorized by the deodorizing device 13, and then mixed with the outside air in the dilution block 24 and diluted, and then discharged to the outside.
[0017]
Here, the exhaust heat generated when the deodorizing device 13 is heated and deodorized is radiated by the deodorizing device 13 and the heat radiating duct portion 25. The air around the deodorizing device 13 and the heat radiating duct portion 25 is heated by heat radiation from the deodorizing device 13 and the heat radiating duct portion 25, and the heated air rises upward. Then, as described above, since the air inlet 9 is disposed substantially above the heat radiating duct 25, the heated air is disposed of from the air inlet 9 as shown by the arrow A in FIGS. It flows into the passage 8 formed at the upper edge of the apparatus 1, flows in the upper part of the passage 8 from the primary tank 3 side to the secondary tank 5 side as shown by the arrow b, and the suspended piece of the secondary tank 5 6 flows into the secondary tank 5 from the supply opening 22 provided in FIG. In this case, since the shielding plate 23 is provided at the front portion of the supply opening 22 of the passage 8, the heated air smoothly flows into the secondary tank 5 from the supply opening 22 without proceeding further. It will be. Although the heated air flows as described above, since the exhaust port portion 10 is provided with the blocking portion 11 so as not to open into the passage 8 as described above, the intake port portion 9 and the exhaust port portion are provided. 10 are disposed close to each other (for example, the intake port portion 9 and the exhaust port portion 10 are disposed on the same surface of the side wall of the garbage treatment tank 1 as shown in the attached drawings). The heated air that has flowed in does not short pass to the exhaust port 9.
[0018]
The heated air that has flowed into the secondary tank 5 as described above heats and dries the garbage treatment material 30 stored in the secondary tank 5 being stirred by the rotation of the stirring means 19, and is fresh. By supplying fresh air, microorganisms living in the garbage treatment material 30 in the secondary tank 5 are activated to improve the garbage treatment capacity. Even if the tank 5 overflows, the secondary tank 5 is effectively decomposed. The heated air supplied to the secondary tank 5 passes through the overflow opening 4 provided in the partition 2 and is supplied into the primary tank 3 as shown by an arrow D in the accompanying drawings. The existing garbage treatment material 30 is heated and fresh air is supplied to activate the microorganisms living in the garbage treatment material 30 in the primary tank 3 to improve the garbage treatment capacity. It is. As described above, the heated air heated by the exhaust heat when the deodorizing device 13 is heated and deodorized is sequentially supplied to the secondary tank 3 and the primary tank 5 to effectively perform the decomposition process of the garbage.
[0019]
And the exhaust_gas | exhaustion which generate | occur | produced in the garbage processing tank 1 is discharged | emitted from the exhaust port part 10 to the exhaust path 12 as shown by the arrow H of an accompanying drawing as mentioned above.
In the embodiment shown in the accompanying drawings, an example in which the upper end of the partition 2 is notched and the overflow opening 4 is provided is shown. However, the upper end of the partition 2 is lower than the upper end of the garbage treatment tank 1. By doing so, the upper space part of the partition 2 may be used as the overflow opening 4, or a hole may be formed in the partition 2 as the overflow opening 4.
[0020]
Here, as shown in FIG. 5, when the ceiling portion 14 of the passage 8 is inclined so as to rise upward from the primary tank 3 side to the secondary tank 5 side, it flows into the passage 8 from the intake port portion 9 and is heated. The air thus smoothly flows to the secondary tank 5 side, and the heated air that has flowed into the passage 8 more smoothly flows to the secondary tank 5 side without short-passing the exhaust port 9.
[0021]
As shown in the attached drawings, if an inclined guide plate 15 is provided above the deodorizing device 13 to guide and introduce hot air into the air inlet 9 of the garbage treatment tank 1, the deodorizing device 13 and The air around the heat radiating duct 25 is heated and raised by the heat released from the deodorizing device 13 and the heat radiating duct 25, and this heated air is collected by the inclined guide plate 15 and smoothly guided to the air inlet 9. Therefore, the heated air heated by the exhaust heat from the deodorizing device 13 and the heat radiating duct portion 25 can be effectively collected and supplied to the intake port portion 9.
