Description

【0001】
【発明の属する技術分野】
本発明は、飲食店の厨房等から出る生ゴミを微生物を含むバイオチップを使用して消滅処理する生ゴミ処理機に関し、特に、生ゴミとバイオチップとの攪拌を行う攪拌機構の改良に関するものである。
【0002】
【従来の技術】
従来より、微生物による生ゴミの分解作用を利用した消滅型の生ゴミ処理機が知られている。この生ゴミ処理機は処理槽(貯留ドラム)に予めバイオチップ(処理材として、例えば杉チップに分解作用を有する土壌細菌等の微生物を付着培養させたもの)が所定量収容されており、この処理槽に生ゴミが投入されると、微生物の分解作用を促進するために、所定の時間毎に、所定の時間だけ、生ゴミとバイオチップとの攪拌を行う必要がある。
【0003】
すなわち、生ゴミ投入時にまず攪拌して生ゴミの表面にバイオチップを付着接触させ、このバイオチップに住み着いている微生物が生ゴミに取りついて、発酵等により分解するもので、混合後には好気性細菌の働きが活性化し、その後の静置状態では嫌気性細菌による分解を行って生ゴミを主にガスと水とに分解して消滅処理するもので、所定時間毎に攪拌と静置とを繰り返して投入された生ゴミの殆どを1日程度で消滅させるものである。
【0004】
上記のような生ゴミ処理機の攪拌機構としては、特開2000−317432、特開2001−145867、特開2001−149904などに、回転する攪拌羽根を用いた構造が開示されている。
【0005】
これらの攪拌羽根は、処理槽の中心部を横方向に貫通するように回転軸を設置し、この回転軸に放射方向に支柱を立設し、支柱の先端部を螺旋状に連結する帯状の螺旋部材を設置してなるものが一般的である。螺旋部材は回転軸の両端部から互いに巻き方向が逆の螺旋形で、両側の螺旋部材の中央部端部は連結せず、中央部には所定の間隔が設けられている。
【0006】
上記のような攪拌羽根では、その回転軸の回転駆動により螺旋部材が一方向に回転し、処理槽の底壁近傍より収容物を持ち上げると共に、横方向に攪拌するもので、ほぼ中央に投入された生ゴミは上記攪拌羽根で持ち上げられて側方へ移動し、さらに中央方向へも移動して、全体に分散してバイオチップとの混合攪拌が行われる。
【0007】
上記のような攪拌を行うについて、前述の先行例にも見られるように、両側の巻き方向が異なる螺旋部材は中央部では連結しておらず、中央部分に間隔が形成される。これは両側の螺旋部材同士が互いに斜めにV字状に結合されると、この部分に生ゴミが噛み込むように引っ掛かって攪拌が阻害されるのを防止するためで、投入される生ゴミの一般的な大きさに対応した間隔である。
【0008】
【発明が解決しようとする課題】
ところで、上記のような消滅型の生ゴミ処理機においては、発酵・分解できるのは生ゴミの有機物だけであり、肉類、牛・豚の小さな骨、鶏の骨、魚、魚の骨、穀物、茶かす、果物、野菜、野菜の芯、卵の殻、菓子類などが投入処理できるが、プラスチック・ゴム類、金属・ガラス類、紙類、繊維類、貝殻類、牛・豚の大きな骨などの消滅しないものの投入が禁止されている。また、玉葱の皮などのように消滅に時間のかかるものや、同じ種類の生ゴミの大量投入が禁止されている。
【0009】
しかし、不注意などによって、予期していない多量の生ゴミが一度に投入された場合などには、例えばデンプン質などが多量に投入され水分により粘性を増して大きな固まりとなったり、生ゴミが互いに絡み合って大きな固まりとなったりして、通常設定されている中央部の間隔ではこの固まりが通過せず、挟まるように詰まって、十分な攪拌機能が得られず攪拌不能となったり、螺旋部材に引っ掛かって過大な負荷が作用して攪拌羽根、駆動機構の故障発生要因となる場合がある。
【0010】
上記詰まりの問題は、生ゴミの投入種類、量を守ってもらえば解消するが、このような生ゴミ投入があっても故障が発生することは最低限回避するように設けることが要求される。これに対応し、前述の両側の螺旋部材の中央部での間隔を広くとると、この部分への上記のような生ゴミの固まりが詰まることは防止できるが、上記間隔が広いことは、通常の生ゴミ投入においては、この中央部分の生ゴミおよびバイオチップに対しては螺旋部材が作用せず、攪拌が十分に行えない領域が発生することになり、バイオチップの働きを十分に利用できず、処理能力の低下を招く問題がある。
【0011】
そこで、本発明はこの点に鑑み、不適切な生ゴミが投入されて固まりが発生しても、両側の螺旋部材の中央部間隔を広くとって上記固まりが中央部間隔につまらないようにして故障発生要因を解消すると共に、中央部分についても良好な攪拌が行えるようにした消滅型の生ゴミ処理機を提供することを目的とする。
【0012】
【課題を解決するための手段】
本発明の生ゴミ処理機は、駆動手段によって回転する攪拌羽根を備えた処理槽内に生ゴミを分解処理するバイオチップを収容し、生ゴミの投入に伴い上記バイオチップを攪拌する生ゴミ処理機において、
前記攪拌羽根は、処理槽中心部の回転軸と、前記回転軸両端部からそれぞれ中央部に向けて軸方向および回転位相方向に略等間隔に放射方向に立設された支柱部材と、前記回転軸の両端部の支柱部材の先端部から順に支柱部材の先端部を連結するように両側で異なる巻き方向に設けられ、互いの中央側端部が所定距離離れている2つの螺旋部材と、前記回転軸の中央部位に隣接する支柱部材とは異なる位相角度に少なくとも1本の放射方向に立設された攪拌棒とで構成されてなることを特徴とするものである。
【0013】
前記回転軸の中央部位における前記両側の螺旋部材の最中央側の支柱部材は位相角度が180度異なり、該支柱部材と位相角度が90度異なる位置に2本の前記攪拌棒が放射方向に立設されてなるものが好適である。
【0014】
前記攪拌棒は、先端部に固着された攪拌ブレードを備えたものが好ましい。この攪拌ブレードは、取付角度が可変であるものが好適である。
【0015】
前記回転軸は、処理槽のフランジ面に接近して固着された保護カバーを備えるのが好ましい。
【0016】
【発明の効果】
以上のような本発明によれば、攪拌羽根を、回転駆動される回転軸と、この回転軸に略等間隔に放射方向に立設された支柱部材と、順に支柱部材の先端部を連結するように両側で異なる巻き方向で中央部位が互いに所定距離離れている2つの螺旋部材と、この中央部位に隣接する支柱部材とは異なる位相角度に立設された攪拌棒とで構成したことにより、螺旋部材の中央部間隔が広いためにこの部分に生ゴミの固まりが詰まることがなく、攪拌羽根に過大な負荷が作用せず故障発生要因を取り除くことができる。また、中央部位には攪拌棒を立設したことにより、螺旋部材がとぎれて攪拌されない部分をこの攪拌棒によって攪拌して、全体として良好な攪拌作用を得ることができ、バイオチップの作用を十分に発揮させて能力通りの生ゴミの消滅処理が行える。
【0017】
前記回転軸の中央部位における前記両側の螺旋部材の最中央側の支柱部材は位相角度が180度異なり、該支柱部材と位相角度が90度異なる位置に2本の前記攪拌棒を放射方向に立設したものでは、詰まり防止効果と攪拌性能の両立を図り、各攪拌棒の負担も軽減する。
【0018】
前記攪拌棒先端部に攪拌ブレードを備えると、より中央部分の攪拌が良好に行える。この攪拌ブレードの取付角度を可変とすると、負荷の増大を抑制しつつより広い範囲の攪拌が行える。また、攪拌棒または攪拌ブレードの先端は処理槽内面に接近していることで、壁面にこびりつく生ゴミの引き剥がしが行える。
【0019】
前記回転軸に処理槽のフランジ面に接近して保護カバーを備えると、回転軸外周の隙間からのバイオチップ流出が防止でき、回転軸を支承するベアリングユニットへの汚染が防止できる。
【0020】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を詳細に説明する。図1はこの実施形態の生ゴミ処理機の正面図、図2はその側面図、図3は図1のX−X断面図、図4は図3の攪拌羽根の平面図、図5はその正面図、図6は図4のY−Y断面図、図7は回転軸の端部断面図、図8は処理槽の左側フランジ板の側面図である。
【0021】
本実施形態の生ゴミ処理機1(消滅機)は、ボックス状のケーシング2内に処理槽3が設置され、この処理槽3内には駆動手段5(図2参照)によって回転する攪拌羽根4(図3参照)が設置されて、処理槽3に収容したバイオチップBに対し投入された生ゴミAを攪拌混合し、生ゴミAを消滅処理するものである。
【0022】
上記処理槽3は、断面が円形で横置き円筒状のドラム部31と、該ドラム部31の斜め上部に角筒状に延びる投入口部32とを備えてなる。この処理槽3のドラム部31の底部が、両側の支持部33,34によってケーシング2の底壁21に支持され、投入口部32の上端部がケーシング2の上壁22に開口された投入口23に連結されている(図3参照)。このケーシング2の投入口23は、窓部を有する投入口蓋24によって開閉される。
【0023】
処理槽3のドラム部31の両端部近傍における前記支持部33,34で保持された底部分には、それぞれ底部開口31aを有し、支持部33,34はこの底部開口31aを囲む支柱状に形成され、この支持部33,34の底面も開口し、金網35が設置されてなる。そして、本実施形態の生ゴミ処理機1は、土(地面)の上に設置して、処理槽3に収容したバイオチップBが底部開口31aから支持部33,34内に充填され、土と接触するようになっている。
【0024】
前記処理槽3に設置される攪拌羽根4は、処理槽3のドラム部31の中心部を横方向に貫通する回転軸41と、この回転軸41に立設された支柱部材42と、両側の支柱部材42の先端部を連結する2つの螺旋部材43,44と、中央部位に放射方向に立設された攪拌棒45,45とを備えてなる。
【0025】
前記回転軸41の両端軸部41aは、ドラム部31の両側フランジ板31b,31cより外側に突出し、この両端軸部41aがフランジ板31b,31cの外面に設置されたベアリングユニット55に回転可能に支障されている。
【0026】
前記支柱部材42は、処理槽3内の回転軸41の両端部からそれぞれ中央部に向けて軸方向および回転位相方向に略等間隔に放射方向に立設されている。この支柱部材42は中央の攪拌棒45を含めて軸方向に略等ピッチで立設され、片側に6本ずつ両側で12本の支柱部材42が、中央に2本の攪拌棒45が立設されている。回転軸41の両端部の支柱部材42は位相角度が180度異なる位置に立設され、これから中心側に順に位相角度が90度ずつずれた位置に支柱部材42が立設されている。中央より右側半分(6本)の支柱部材42は、図4の回転軸41を右側面から見た場合に、外側から順に左回りに90度ずつ位相がずれて設置され、左側半分(6本)の支柱部材42は外側から順に右回りに90度ずつ位相がずれて設置され、両側で位相のずれる方向が逆となっている。
【0027】
そして、回転軸41の中央部位における両側の最中央側の支柱部材42は位相角度が180度異なり、両者の間が中央間隔Dに形成される。中央部位の2本の攪拌棒45と、隣接する最中央側の支柱部材42との位相角度は90度異なっている。
【0028】
各支柱部材42および攪拌棒45は、先端部がドラム部31の円筒内面に接近する位置にまで延ばされ、この先端部に螺旋部材43,44および攪拌ブレード46が固着される。両側の螺旋部材43,44は、それぞれ回転軸41の両端部の支柱部材42の先端部から中央位置に向けて順に支柱部材42の先端部を連結するように帯状に形成され、両側で異なる巻き方向に設けられ、互いの中央側端部が所定距離離れて、中央間隔Dが形成される。この螺旋部材43,44の外周縁は、ドラム部31の円筒内面に接近した円弧状に形成され、その回転に伴ってドラム部31の円筒内面に沿って移動するようになっている。
【0029】
攪拌棒45の先端の攪拌ブレード46は平板状であり、その中央部が攪拌棒45の先端部に回転軸方向と直交する回転方向と平行にエンドプレート45aを使用して取り付けられている。
【0030】
なお、攪拌ブレード46の外縁は図示のような直線状でなく、螺旋部材43,44と同様にドラム部31の円筒内面に沿った円弧状としてもよい。また、この攪拌ブレード46は、エンドプレート45aの締結角度の変更等により取付角度を可変としてもよい。この攪拌ブレード46の取付角度を回転方向と直交する方向とすると、攪拌範囲が広くなる一方、攪拌負荷が増大し、その角度を変化させることにより攪拌負荷の増大を抑制しつつより広い範囲の攪拌が行える。また、攪拌棒45または攪拌ブレード46の先端は処理槽3内面に接近していることで、壁面にこびりつく生ゴミAの引き剥がしが行える。
【0031】
駆動手段5(図2)は、回転軸41の一端部(図4の右端部)にスプロケット51が固着され、このスプロケット51と駆動モータ52の駆動ギヤ53との間にチェーン54が掛けられ、ケーシング2の底壁21に設置された駆動モータ52の駆動によって回転軸41が回転するようになっている。この駆動手段5により攪拌羽根4を、一方向(例えば図3の矢印R方向)に回転駆動する。なお、メンテナンスその他の要求により、逆方向に回転駆動してもよい。
【0032】
前記処理槽3の一側部(左側)のフランジ板31bは着脱可能に取り付けられ、このフランジ板31bを外した状態で回転軸41をドラム部31内に挿入し、先端軸部41aを他側部(右側)のフランジ板31cの中心孔からベアリングユニット55へ挿入した後、回転軸41の他端軸部41aを一側方のフランジ板31bの中心孔からベアリングユニット55へ挿入しつつ、このフランジ板31bを処理槽3へ取り付けてなる。
【0033】
そして、処理槽3内の回転軸41の両端部に、フランジ板31b,31cの内面に接近して保護カバー47を固着してなる。この保護カバー47は、円板部47aが2分割構造とされ、ネジ締めによって回転軸41に取り付けられ、円板部47aにはフランジ板31b,31cの内面と摺接可能にシール材47b(ネオプレンゴム等)が付設されている。これにより、回転軸41外周とフランジ板31b,31cの中心穴との隙間からのバイオチップBの流出が阻止でき、回転軸41を支承するベアリングユニット55への汚染が防止できる。また、前記保護カバー47を分割構造として後付けすることで、この保護カバー47をフランジ板31b,31cの内面に接近させて取り付け可能であり、隙間の低減調整によりバイオチップBの流出防止効果が高い。
【0034】
前記処理槽3のフランジ板31b,31cの外面には、中心部のベアリングユニット55から放射方向に延びる複数(図の場合4本)の補強リブ31dが付設されている(図8参照)。このフランジ板31b,31cは補強リブ31dにより剛性が高まり、回転軸41および螺旋部材43,44に負荷が作用してたわみが発生した際にも、防振作用により共振、共鳴を抑制でき、振動、騒音、異音の発生が防止できると共にベアリングユニット55の支持剛性が高まり、回転軸41の支持が良好である。
【0035】
両側の螺旋部材43,44の中央部間隔Dは支柱部材42のピッチの約2倍であるが、螺旋部材43,44の位相が180度ずれていることで、同じ位相位置では左右の螺旋部材43,44の間隔はこれより広くなり、中央部位に移動した生ゴミAの固まりが引っ掛かって詰まるのを回避できる。一方、中央部間隔Dの部分における攪拌は、攪拌羽根4の回転に伴い、2本の攪拌棒45とその先端の攪拌ブレード46によりドラム部31の壁面近傍においても十分な持ち上げ作用が得られて攪拌が行われる。
【0036】
前記攪拌棒45は1本でもよく、また攪拌ブレード46は取り付けてなくてもよいが、攪拌効果を上げるためには攪拌ブレード46の設置が好ましく、その長さ、取付角度等は攪拌負荷、攪拌効率等に基づいて適宜設計変更可能である。
【0037】
なお、図1に示すように、ケーシング2の前面には内部に操作パネル、表示盤が設置される左右の制御箱扉25,26が設けられ、一方の側面(図2)には、攪拌羽根4の駆動手段5などのための点検扉27が設けられ、上部には排気ファン28が設置されている。排気ファン28は処理槽3の内部よりエアーを吸引排出する。この排気に伴う処理槽3内へのエアーの導入は、ケーシング2に形成された開口部29からケーシング2内に吸引され、処理槽3内へは上部より導入される。
【0038】
上記のような実施形態の生ゴミ処理機1によれば、両側の螺旋部材43,44の中央部間隔Dが広いためにこの部分に生ゴミAの固まりが詰まることがなく、攪拌羽根4に過大な負荷が作用せず、攪拌棒45とによって処理槽3の全体で良好な攪拌が行え、バイオチップBの性能を十分に発揮させて所望の能力で生ゴミAの消滅処理が行える。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a garbage disposal machine for extinguishing garbage from a kitchen or the like of a restaurant using a biochip containing microorganisms, and more particularly to an improvement in a stirring mechanism for stirring garbage and the biochip. It is.
[0002]
[Prior art]
2. Description of the Related Art An extinguishing-type garbage processing machine that utilizes the decomposition of garbage by microorganisms has been known. In this garbage processing machine, a predetermined amount of a biochip (as a processing material, for example, microorganisms such as soil bacteria having a decomposing effect on cedar chips attached and cultured) is previously stored in a processing tank (storage drum). When the garbage is put into the treatment tank, it is necessary to stir the garbage and the biochip for a predetermined time at a predetermined time in order to promote the action of decomposing microorganisms.
[0003]
In other words, the garbage is first stirred to bring the biochip into contact with the surface of the garbage, and the microorganisms resident on the biochip attach to the garbage and decompose by fermentation, etc., and are aerobic after mixing. The activity of the bacteria is activated, and in the subsequent standing state, it is decomposed by anaerobic bacteria and the raw garbage is mainly decomposed into gas and water to eliminate the garbage. Most of the repeatedly input garbage disappears in about one day.
[0004]
As a stirring mechanism of the above-mentioned garbage disposal machine, JP-A-2000-317432, JP-A-2001-145867, JP-A-2001-149904, and the like disclose a structure using a rotating stirring blade.
[0005]
These stirring blades are provided with a rotating shaft so as to penetrate the center of the processing tank in the lateral direction, and a column is erected in a radial direction on the rotating shaft, and a strip-shaped connecting the tip of the column in a spiral shape. Generally, a spiral member is provided. The spiral member has a spiral shape in which the winding directions are opposite to each other from both ends of the rotating shaft. The ends of the central portions of the spiral members on both sides are not connected, and a predetermined interval is provided in the central portion.
[0006]
In the stirring blade as described above, the helical member rotates in one direction by the rotation drive of the rotating shaft, lifts the contents from the vicinity of the bottom wall of the processing tank, and stirs in the lateral direction. The garbage is lifted by the stirring blades, moves sideways, and further moves toward the center, and is dispersed and mixed with the biochip.
[0007]
Regarding the above-described stirring, as can be seen from the above-mentioned prior example, the spiral members having different winding directions on both sides are not connected at the central portion, and an interval is formed at the central portion. This is because when the spiral members on both sides are connected to each other in a diagonal V-shape, the garbage is caught in this portion so as to prevent the garbage from being caught and hindering the stirring. This is an interval corresponding to a general size.
[0008]
[Problems to be solved by the invention]
By the way, in the disappearing type garbage processing machine as described above, only organic matter of garbage can be fermented and decomposed, and meat, small bones of cattle and pigs, chicken bones, fish, fish bones, grains, Tea cakes, fruits, vegetables, vegetable cores, egg shells, confectionery, etc. can be input and processed, but plastics, rubbers, metals and glass, papers, textiles, shells, large bones of cows and pigs, etc. The entry of those that do not disappear is prohibited. In addition, it is forbidden to throw in a long time such as onion skin or the like, or to put a large amount of the same kind of garbage.
[0009]
However, if a large amount of unexpected garbage is thrown in at once due to carelessness, for example, a large amount of starch or the like will be thrown in and will become viscous due to moisture, resulting in a large lump or garbage. It becomes entangled with each other to form a large lump, and this lump does not pass at the normally set center interval, and becomes jammed so as to be sandwiched. In some cases, an excessive load acts on the stirrer and causes a failure of the stirring blade and the drive mechanism.
[0010]
The problem of clogging can be solved by observing the type and amount of garbage input, but it is required to provide at least a minimum occurrence of a failure even when such garbage is input. . In response to this, if the space at the center of the spiral members on both sides is widened, it is possible to prevent the lump of garbage in this part from being clogged as described above. The spiral member does not act on the garbage and biochip in the central part, and an area where stirring cannot be performed sufficiently occurs, so that the function of the biochip can be fully utilized. Therefore, there is a problem that the processing capacity is reduced.
[0011]
In view of this point, the present invention takes into account the problem that even if improper garbage is thrown in and lumps are formed, the gap between the center portions of the spiral members on both sides is widened so that the lump does not become dull at the gaps between the centers. It is an object of the present invention to provide a garbage disposal machine of the disappearance type which eliminates the generation factor and enables good stirring to be performed even in the central portion.
[0012]
[Means for Solving the Problems]
The garbage disposal machine of the present invention accommodates a biochip for decomposing garbage in a treatment tank provided with a stirring blade rotated by a driving means, and agitates the biochip with the addition of the garbage. On the machine,
The stirring blade has a rotating shaft at the center of the processing tank, a column member that is erected in the radial direction at substantially equal intervals in both the axial direction and the rotational phase direction from both ends of the rotating shaft toward the center, and the rotating shaft. Two helical members provided in different winding directions on both sides so as to connect the tip portions of the pillar members in order from the tip portions of the pillar members at both end portions of the shaft, and two helical members whose center side ends are separated by a predetermined distance, It is characterized by comprising a support member adjacent to the central portion of the rotating shaft and at least one stirring rod erected in a radial direction at a different phase angle.
[0013]
The center member of the spiral member on the center side of the rotation shaft has a phase angle different by 180 degrees from the center of the spiral member on both sides, and the two stirring rods stand in a radial direction at positions different from the support member by 90 degrees in phase angle. What is provided is preferable.
[0014]
The stirring rod preferably has a stirring blade fixed to the tip. The stirring blade preferably has a variable mounting angle.
[0015]
It is preferable that the rotating shaft includes a protective cover fixed to the processing tank close to the flange surface.
[0016]
【The invention's effect】
According to the present invention as described above, the stirring blade is connected to the rotating shaft that is driven to rotate, the strut member that is erected in the radial direction at substantially equal intervals on the rotating shaft, and the tip of the strut member in this order. As described above, two spiral members whose central portions are separated by a predetermined distance from each other in different winding directions on both sides, and a stirrer bar that is erected at a different phase angle from a column member adjacent to the central portion, Since the space between the center portions of the spiral members is wide, garbage is not clogged in this portion, and an excessive load does not act on the stirring blade, so that the cause of failure can be eliminated. In addition, since a stirring rod is provided upright at the center part, a portion where the spiral member is cut off and not stirred can be stirred by the stirring rod, and a good stirring action can be obtained as a whole, and the action of the biochip can be sufficiently performed. Garbage can be eliminated according to the ability.
[0017]
At the center portion of the rotating shaft, the most central support members of the spiral members on both sides have a phase angle different by 180 degrees, and the two stirring rods are set in a radial direction at positions different from the support members by a phase angle of 90 degrees. With this arrangement, both the effect of preventing clogging and the stirring performance are achieved, and the burden on each stirring rod is reduced.

The support members 42 at both ends of the rotating shaft 41 are erected at positions where the phase angles are different by 180 degrees, and the support members 42 are erected at positions where the phase angles are sequentially shifted by 90 degrees toward the center side. When the rotation shaft 41 of FIG. 4 is viewed from the right side, the support members 42 on the right half (six) are arranged out of phase from the outside by 90 degrees counterclockwise from the outside, and the left half (six). The column members 42) are installed with a phase shift of 90 degrees clockwise in order from the outside, and the directions of the phase shifts are opposite on both sides.
[0027]
Then, the support members 42 at the center on both sides in the center portion of the rotating shaft 41 have a phase angle different by 180 degrees, and a center space D is formed between them. The phase angles of the two stirring rods 45 at the central portion and the adjacent centralmost column member 42 differ by 90 degrees.
[0028]
Each of the support members 42 and the stirring rod 45 is extended to a position where the distal end thereof approaches the inner surface of the cylinder of the drum portion 31, and the spiral members 43 and 44 and the stirring blade 46 are fixed to the distal end portion. The spiral members 43 and 44 on both sides are formed in a band shape so as to connect the distal ends of the column members 42 in order from the distal ends of the column members 42 at both ends of the rotary shaft 41 toward the center position, and different windings are formed on both sides. And the center ends are separated by a predetermined distance to form a center interval D. The outer peripheral edges of the spiral members 43 and 44 are formed in an arc shape approaching the inner surface of the cylinder of the drum portion 31, and move along the inner surface of the cylinder of the drum portion 31 with the rotation.

On the outer surfaces of the flange plates 31b and 31c of the processing tank 3, a plurality (four in the figure) of reinforcing ribs 31d extending in the radial direction from the central bearing unit 55 are attached (see FIG. 8). The rigidity of the flange plates 31b and 31c is increased by the reinforcing ribs 31d, and even when a load is applied to the rotating shaft 41 and the helical members 43 and 44 to cause deflection, resonance and resonance can be suppressed by vibration damping, and vibration can be suppressed. In addition, the generation of noise and noise can be prevented, and the rigidity of the support of the bearing unit 55 is increased, so that the support of the rotating shaft 41 is good.
[0035]
The center interval D between the spiral members 43 and 44 on both sides is about twice the pitch of the support members 42. However, since the phases of the spiral members 43 and 44 are shifted by 180 degrees, the left and right spiral members are in the same phase position. The interval between 43 and 44 becomes wider than this, and it is possible to prevent the lump of the garbage A moved to the central portion from being caught and clogged. On the other hand, the stirring in the portion at the center interval D is accompanied by the rotation of the stirring blade 4, and the two stirring rods 45 and the stirring blade 46 at the tip thereof provide a sufficient lifting action even near the wall surface of the drum portion 31. Stirring is performed.
[0036]
The number of the stirring rod 45 may be one, and the stirring blade 46 may not be attached. However, it is preferable to install the stirring blade 46 in order to enhance the stirring effect. The design can be changed as appropriate based on efficiency or the like.
[0037]
