この発明は、投入される都市ゴミなどの見かけ上の嵩の大小に拘らず常に回転刃間の中央へ投入物を誘導し、破砕不可能な剛性の高い投入物が混入した時には装置を損傷する前に処理して保全し、さらに回転刃の摩耗によって破砕効率が低下してきた場合でもこれを十分補って長期の運転に耐えるものである。   This invention always guides the input to the center between the rotating blades regardless of the apparent bulk of the municipal waste that is input, and damages the device when a highly rigid input that cannot be crushed is mixed. Even if the processing efficiency is reduced by pretreatment, and the crushing efficiency is reduced due to the wear of the rotary blade, this can be sufficiently compensated for long-term operation.

しかし、上記の特許文献1記載の発明は、構造が複雑な上に、廃棄物を回転刃によって剪断・破砕するものであるため回転刃の磨耗損傷が著しく、それによる作業効率の低下が問題となっていた。   However, the invention described in Patent Document 1 has a complicated structure, and waste is sheared and crushed by the rotary blade, so the wear damage of the rotary blade is significant, resulting in a decrease in work efficiency. It was.

本発明は上記の点に鑑みなされたものであり、破砕歯の磨耗や損傷が殆どなく永き使用に耐えると共に、破砕された廃棄物の分別も自動的に行え資源の再利用を有効に行える産業廃棄物用破砕機を提供するものである。   The present invention has been made in view of the above points, and is an industry that can withstand long-term use with almost no wear or damage on the crushing teeth, and can automatically sort crushed waste and effectively reuse resources. A waste crusher is provided.

本発明の要旨とするところは、基台と、この基台上部に破砕部を構成し、前記破砕部は、ケーシングとこのケーシング内に平行かつ一定のクリアランスを有して軸支した一対の回転軸を備え、前記回転軸に周面が平滑な第1破砕歯及び周面に凹みを構成した第2破砕歯を固定したことを特徴とする産業廃棄物用破砕機である。   The gist of the present invention is that a base and a crushing part are formed on the upper part of the base, and the crushing part is a pair of rotations that are supported in a parallel and constant clearance in the casing. An industrial waste crusher comprising a shaft, wherein a first crushing tooth having a smooth peripheral surface and a second crushing tooth having a recess formed on the peripheral surface are fixed to the rotating shaft.

また、本発明の要旨とするところは、前記第1破砕歯と第2破砕歯をリング状に構成し、この複数の第1破砕歯と複数の第2破砕歯を一対の回転軸に交互に取り付けたことを特徴とする産業廃棄物用破砕機である。   Further, the gist of the present invention is that the first crushing teeth and the second crushing teeth are configured in a ring shape, and the plurality of first crushing teeth and the plurality of second crushing teeth are alternately arranged on a pair of rotating shafts. An industrial waste crusher characterized by being attached.

また、本発明の要旨とするところは、前記第2破砕歯に構成した凹みを、第2破砕歯の周面をローラの半径に平行な直線と、この直線に直交する直線によって切欠いて構成し、かつ第2破砕歯の周面の4カ所に90度間隔に2個ずつ対向して構成したことを特徴とする産業廃棄物用破砕機である。   Further, the gist of the present invention is that the recess formed in the second crushing tooth is formed by cutting out the peripheral surface of the second crushing tooth by a straight line parallel to the radius of the roller and a straight line orthogonal to the straight line. And it is the industrial waste crusher characterized by being configured to be opposed to each other at four intervals of 90 degrees at four locations on the peripheral surface of the second crushing tooth.

本発明は上記の如き構成であるため、産業廃棄物を剪断することなく破砕するから、破砕歯の磨耗や損傷が殆どなく永き使用に耐えることができる。すなわちガレキ類を剪断せずに、第2破砕歯の周面に構成した凹みを利用して圧縮して細かく粉砕して破砕歯の間から排出すると共に、木屑やプラスチック、アスファルト等の柔らかいものは粉砕せずに圧縮して紙状にして排出し、破砕物の分別も自動的に行い資源の再利用を有効に行えるという効果を奏する。   Since the present invention is configured as described above, the industrial waste is crushed without shearing, so that the crushed teeth are hardly worn or damaged and can be used for a long time. That is, without shearing the rubble, using the dents formed on the peripheral surface of the second crushing tooth, it is compressed and finely crushed and discharged from between the crushing teeth. It compresses without crushing, discharges it in paper form, and produces the effect that the recycle of resources can be effectively performed by automatically separating the crushed material.

また、前記ローラ上に第1破砕歯と第2破砕歯をリング状に構成して、複数個を交互に取り付けた場合には、破砕歯の増減によりローラの長さを調節できる。   In addition, when the first crushing teeth and the second crushing teeth are configured in a ring shape on the roller and a plurality of crushing teeth are alternately attached, the length of the roller can be adjusted by increasing or decreasing the crushing teeth.

また、前記第2破砕歯に構成した凹みを、第2破砕歯の周面をローラの半径に平行な直線と、この直線に直交する直線によって切欠いて構成し、かつ第2破砕歯の周面の4ヶ所に90度間隔に2個ずつ対向した場合は、凹みの効果を最大に発揮できる。   Further, the recess formed in the second crushing tooth is formed by cutting out the peripheral surface of the second crushing tooth by a straight line parallel to the radius of the roller and a straight line orthogonal to the straight line, and the peripheral surface of the second crushing tooth When two of them are opposed to each other at intervals of 90 degrees, the effect of the dent can be maximized.

The roller 7 is formed by alternately mounting a plurality of first crushing teeth 8 and a plurality of second crushing teeth 9 on a rotating shaft 6 pivotally supported on the casing 5.

前記第1破砕歯8は所定の厚みを有し周面を平滑にしたリング状であり、第2破砕歯9は第1破砕歯8と同一の厚さからなり周面に複数の凹み91を構成したリング状である。
前記凹み91は、図5に示すように第2破砕歯9の周面の4カ所に90度間隔に2個ずつ対向して構成してあるため、合計8個の凹み91が構成されている。
The first crushing tooth 8 has a ring shape with a predetermined thickness and a smooth peripheral surface, and the second crushing tooth 9 has the same thickness as the first crushing tooth 8 and has a plurality of dents 91 on the peripheral surface. It is a configured ring shape.
As shown in FIG. 5, the recesses 91 are configured so as to be opposed to each other at four positions on the peripheral surface of the second crushing tooth 9 at intervals of 90 degrees, so that a total of eight recesses 91 are configured. .

この凹み91は、第2破砕歯9の周面をローラ7の半径Rに平行な直線R1と、この直線R1に直交する直線R2によって切欠いてなる。この形状を図6に基づいて説明する。
基軸となるローラ7の水平な半径R(本実施例では450mm)と平行で距離D(半径Rの約1/5)だけ下方に位置する直線R1上の、第2破砕歯9の表面から半径Rの約1/10内側の点Pまでを切り欠いて切欠面Mを構成する。この点Pから直線R2に沿って切り欠いて切欠面Nを構成し、第2破砕歯9の周面に略三角形状の凹み91を構成する。
The recess 91 is formed by notching the peripheral surface of the second crushing tooth 9 with a straight line R1 parallel to the radius R of the roller 7 and a straight line R2 orthogonal to the straight line R1. This shape will be described with reference to FIG.
The radius from the surface of the second crushing tooth 9 on the straight line R1 that is parallel to the horizontal radius R (450 mm in this embodiment) of the roller 7 that is the base shaft and that is positioned downward by a distance D (about 1/5 of the radius R). A notch plane M is formed by notching up to a point P that is about 1/10 inside of R. A notch surface N is formed by cutting out from this point P along the straight line R <b> 2, and a substantially triangular recess 91 is formed on the peripheral surface of the second crushing tooth 9.

本実施例では図3に示すように、第1破砕歯8と第2破砕歯9のそれぞれ9個を交互に配置してローラ7を構成し、かつ一対のローラ7,7の第1破砕歯8と第2破砕歯9がそれぞれ対向するように配置してある。
なお、前記凹み91の個数や配置する位置、凹みの大きさ、形状等は任意に決定できる。
In this embodiment, as shown in FIG. 3, each of the first crushing teeth 8 and the second crushing teeth 9 is alternately arranged to constitute a roller 7, and the first crushing teeth of the pair of rollers 7, 7 are used. 8 and the 2nd crushing tooth 9 are arrange | positioned so that it may each oppose.
It should be noted that the number of the recesses 91, the position of the recesses 91, the size and shape of the recesses can be arbitrarily determined.

基台1の下部には篩部2を設ける。この篩部2はバイブレータ21を備えていて、破砕された廃棄物Wを受けて一定の大きさに選別するのである。   A sieve part 2 is provided at the lower part of the base 1. The sieving unit 2 includes a vibrator 21 and receives the crushed waste W and sorts it into a certain size.

次に、本実施例の産業廃棄物用破砕機の作用について説明する。
まず、モータ3を駆動してローラ7,7を互いに内側に回転させる一方、産業廃棄物の投入口10より廃棄物Wを投入する。
投入された廃棄物Wはローラ7,7の上に落下して、ローラ7,7に巻き込まれながらクリアランスCを通過していくのである。
Next, the effect | action of the industrial waste crusher of a present Example is demonstrated.
First, the motor 3 is driven to rotate the rollers 7 and 7 inward, while the waste W is introduced from the industrial waste inlet 10.
The thrown-in waste W falls on the rollers 7 and 7 and passes through the clearance C while being wound around the rollers 7 and 7.

図6に示すように、廃棄物Wは第2破砕歯9の凹み91の切欠面Mと切欠面N上に載置され、かつ第1破砕歯8の表面によって挟まれる。この後、廃棄物Wはローラ7,7の回転に伴って破砕されていく。
このように、廃棄物Wが凹み91に入り込むことで、ローラ7,7に大きな力がかかるのを防ぐことができるため故障を防ぎ、ローラ7,7の磨耗も防止できる。さらに廃棄物Wは適度な大きさに破砕されるのである。
As shown in FIG. 6, the waste W is placed on the cut surface M and the cut surface N of the recess 91 of the second crushing tooth 9 and is sandwiched by the surface of the first crushing tooth 8. Thereafter, the waste W is crushed as the rollers 7 and 7 rotate.
In this way, since the waste W enters the recess 91, it is possible to prevent a large force from being applied to the rollers 7 and 7, thereby preventing a failure and preventing the rollers 7 and 7 from being worn. Further, the waste W is crushed to an appropriate size.

上述の一度の破砕作業で、廃棄物Wは全体の60〜70%が、0〜10mm程度の大きさに破砕され、25%は破砕されずに落下する。そのため、従来品に比べて単体破砕の性能がアップした。廃棄物Wを破砕する処理能力は、クリアランスCが4.5mmのとき1時間あたり4.8立方米である。
また、従来の破砕機では40mm程度までしか破砕できなかったため、廃棄物Wを資源として再使用することはできなかったが、本実施例では、サンドプレッシャーのような効果も有しているから、上記のように10mmまで細かく破砕できるのである。
さらに従来のサンドクラッシャでは木屑やプラスチックを処理することはできなかった。
In the above-described one crushing operation, 60 to 70% of the waste W is crushed to a size of about 0 to 10 mm, and 25% falls without being crushed. Therefore, the single crushing performance is improved compared to the conventional products. The processing capacity for crushing the waste W is 4.8 cubic rice per hour when the clearance C is 4.5 mm.
In addition, since the conventional crusher could only crush up to about 40 mm, the waste W could not be reused as a resource, but in this example, it also has an effect like sand pressure, As described above, it can be finely crushed to 10 mm.
Furthermore, conventional sand crushers were not able to treat wood chips and plastic.

図7(A)に示すものは上記の作業で破砕された廃棄物Wであり、10mmより小さいものを示している。これらの廃棄物Wは資源(土砂)として再利用できる。特に5mmの大きさに再生すれば砂として再利用できる。
一方、図7(B)に示すものは、破砕の程度が小さく10mm以上のガレキ類と、破砕されなかった木屑Kやプラスチック、アスファルト等の弾性の強い廃棄物が混在したものである。
The thing shown to FIG. 7 (A) is the waste W crushed by said operation | work, and has shown the thing smaller than 10 mm. These wastes W can be reused as resources (earth and sand). In particular, it can be reused as sand if it is regenerated to a size of 5 mm.
On the other hand, what is shown in FIG. 7B is a mixture of rubble having a small degree of crushing of 10 mm or more and highly elastic waste such as wood chips K, plastic, and asphalt that have not been crushed.

上述のように本実施例の産業廃棄物用破砕機によれば、コンクリートガラ、瓦、レンガ、ガラス等のガレキ類のように硬い廃棄物は、ローラ7,7の作用で破砕されて、0〜10mm程度の大きさになる。この段階で廃棄物Wはリサイクル可能な資源となるのである。   As described above, according to the industrial waste crusher of the present embodiment, hard waste such as debris such as concrete trash, roof tiles, bricks, and glass is crushed by the action of the rollers 7 and 0, and 0 The size is about 10 mm. At this stage, the waste W becomes a recyclable resource.

前記破砕作業中に、凹み91に廃棄物Wの破片が残ることがあるが、その場合はローラ7の回転と共に自然落下することに加えて、この凹み91が略三角形状であるため、当該凹み91に次の廃棄物Wが入ったときに、その廃棄物Wが残存している廃棄物を削る作用をするので、凹み91の目詰まりはおこらないのである。   During the crushing operation, debris of waste W may remain in the recess 91. In this case, in addition to the natural fall with the rotation of the roller 7, the recess 91 has a substantially triangular shape. When the next waste W enters 91, the waste W acts to scrape the remaining waste, and the clogging of the recess 91 does not occur.

また破砕歯の肉盛はなく、第1破砕歯8と第2破砕歯9は、1個ごとの交換ができるため低コストでメンテナンスの手間がかからず、前記ローラ7,7は全体が均一に減ってくるため回転軸6,6を1年に1mm程度中心に寄せれば破砕能力が持続する。
この場合も、前記スペーサ51を幅の狭いものに交換することで、回転軸6,6を中心に寄せることができ、クリアランスCを容易に変更できる。
Moreover, there is no crushing of the crushing teeth, and the first crushing teeth 8 and the second crushing teeth 9 can be replaced one by one, so the maintenance cost is low and the rollers 7 and 7 are uniform throughout. If the rotary shafts 6 and 6 are moved to the center of about 1 mm per year, the crushing ability will be maintained.
In this case as well, by replacing the spacer 51 with a narrower one, the rotary shafts 6 and 6 can be moved to the center, and the clearance C can be easily changed.

さらに木やプラスチックあるいはアスファルトのように柔らかいものは破砕されずに、ローラ7,7によって圧縮され引き伸ばされて落下していき、その後篩部2で選別されるのである。   Further, a soft material such as wood, plastic, or asphalt is not crushed but is compressed and stretched by the rollers 7 and 7 to be dropped, and is then sorted by the sieve unit 2.
