Description

【0001】
【発明が属する技術分野】
この発明は、医療廃棄品をその種類に応じて分別して破砕処理することができる医療廃棄物などの分別破砕装置に関するものである。
【0002】
【従来の技術】
病院から排出される医療廃棄物は、注射器、薬剤容器、チューブ、フィルタなど種々雑多であり、病院側では、これらの処理を一括して専門業者の手に委ねている。この廃棄物の排出量は、中小クラスの病院でも月当り数百キログラムに及んでいる。
【0003】
これらの廃棄物は、多種雑多のまま捨てられており、専門業者は、これらを専用の容器に移して自社内に持ち帰り、専用施設で分別処理を行っている。病院側から見たとき、多種雑多の廃棄品は、いわゆるカサ量(容積)が大きくなってしまい、運搬費用さらには処理費用が高くなってしまうという不満があり、また、相手先で分別処理してしまうので、処理コストが見えないという不満もあった。そして、このことが病院の経営コスト負担を招く一因にもなっていた。
【0004】
【発明が解決しようとする課題】
この実状に着目し、従来、実開平8−400号に係る医療器廃棄物粉砕機が提案されたものである。この粉砕機は、注射器、人工透析用フィルタ、チューブなど合成樹脂製の軟質廃棄物を想定したものであり、大半の廃棄物を有効に処理することができたものである。しかし、ガラス容器などいわゆる硬質の廃棄物の破砕処理には向いていないという問題があり、なお改良が求められていた。
【0005】
本発明は、上記した従来技術の問題点に着目してなされたものであり,廃棄物の種類を問わず、これを分別して破砕処理することができる医療廃棄物などの分別破砕装置を提供しようとするものである。
【0006】
【課題を解決するための手段】
上記の目的を達成するために、本発明に係る医療廃棄物などの分別破砕装置は、次のように構成したものである。
【0007】
すなわち、その要旨とするところは、長尺の第1の回転軸と短尺の第2の回転軸を平行に配設し、第1の回転軸の一部にして第2の回転軸と対峙しない部分に硬質の破砕物を潰圧して破砕する潰圧刃を取りつけ、第1の回転軸の他部にして第2の回転軸と対峙する部分と第2の回転軸に軟質の破砕物を切断して破砕する切断刃を取りつけると共に、上記潰圧刃の上部に硬質の破砕物を投入するホッパーを、切断刃の上部に軟質の破砕物を投入するホッパーを設けたことにある。
【0008】
【発明の実施の形態】
以下、この発明に係る医療廃棄物などの分別破砕装置を一実施例について説明する。図1は全体構成を示す縦断正面図、図2は図1に示すX−X線の断面図、図3は同じくY−Y線の断面図にして、1は機械のフレーム 2a〜2cはフレーム1の上部に配設した左右および中間の3つの軸受板 3は左右の軸受板2a、2cに支持して回転自在とした長尺の第1の回転軸 4は左方の軸受板2cと中間の軸受板2bに支持して回転自在とした第2の回転軸である。
【0009】
5は第2の回転軸4が対峙しない部分にして第1の回転軸3に間隔的に取りつけたかぎ爪状の潰圧刃 この潰圧刃5は、ガラス容器など硬質の破砕物Waを受刃6に押圧し、これを潰圧破砕する。7は潰圧刃5、受刃6を囲うようにして設けたケーシング 8は潰圧刃5の上方に設けた破砕物Waの投入用ホッパー 9はケーシング7の下部に設けた排出筒ある。
【0010】
10aは第2の回転軸4に間隔的に取りつけたのこ刃状の切断刃 10bは回転軸4に対峙する第1の回転軸3の部分に間隔的に取りつけたのこ刃状の切断刃である。これら切断刃10a、10bは互いに逆方向に回転し、樹脂袋などの軟質の破砕物Wbを切断刃砕する。11は切断刃10a、10bを囲うようにして設けたケーシング 12は切断刃10a、10bの上方に設けた破砕物Wbの投入用ホッパー 13はケーシング11の下部に設けた排出筒ある。
【0011】
上記の第1の回転軸3と第2の回転軸4は、スプロケットおよびギャなどの伝動手段を介して駆動モータ14によって回転駆動する。第1の回転軸3と第2の回転軸4の速度比は1対4に設定してある。
【0012】
一実施例に係る医療廃棄物などの分別破砕装置の構成は上記の通りであるから,廃棄品がガラス容器、磁器などの場合は、これを右側のホッパー8に投入する。投入された硬質の破砕物Waは、かぎ爪状の潰圧刃5によって受刃6に押圧され、破砕される。そして、細かくなった破砕片が排出筒9から下方に落下する。
【0013】
廃棄物が樹脂容器、チューブなどの場合は、これを左側のホッパー12に投入する。投入された軟質の破砕物Wbは一対の切断刃10a、10bによって切断される。この切断刃10a、10bは、のこ刃状であるために、絡みつくことがなく完全に細かく切断される。そして、細かくなった破砕片が排出筒13から下方に落下する。
【0014】
上記のようにして細片に破砕された廃棄物は、排出筒9,13の下方に設置した収容箱(図示省略)にコンパクトに収納することができる。このように減容化した場合においては、後処理の手間さらにはコストを大幅に軽減することができる。
【0015】
【発明の効果】
このように本発明に係る医療廃棄物などの分別破砕装置によれば、ガラス容器のような硬質の破砕物と、樹脂容器のような軟質の破砕物を分別して破砕することができる。よって種々雑多の医療廃棄物に対応して、これを合理的に減容化することができるという優れた効果を発揮する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus for separating and crushing medical waste and the like, which can sort and crush medical waste according to the type.
[0002]
[Prior art]
Medical waste discharged from hospitals is various such as syringes, drug containers, tubes, and filters, and the hospital collectively entrusts these treatments to specialists. Even small and medium-sized hospitals generate hundreds of kilograms of waste per month.
[0003]
These wastes are thrown away as miscellaneous, and specialists move them to dedicated containers, take them home, and sort them at dedicated facilities. From the hospital's point of view, miscellaneous and miscellaneous waste has a large volume (volume), which is a complaint that transportation costs and disposal costs are high. There was also a complaint that the processing costs were not visible. This also contributed to the hospital's management costs.
[0004]
[Problems to be solved by the invention]
Focusing on this situation, a medical device waste crusher according to Japanese Utility Model Laid-Open No. 8-400 has been proposed. This crusher is intended for soft waste made of synthetic resin such as a syringe, a filter for artificial dialysis, and a tube, and can effectively treat most waste. However, there is a problem that it is not suitable for crushing so-called hard waste such as a glass container, and further improvement has been demanded.
[0005]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide an apparatus for separating and crushing medical waste and the like, which can sort and crush the waste regardless of the kind of the waste. It is to be.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the apparatus for separating and crushing medical waste and the like according to the present invention is configured as follows.
[0007]
That is, the gist of the invention is that a long first rotating shaft and a short second rotating shaft are arranged in parallel, and a part of the first rotating shaft does not face the second rotating shaft. Attach a crushing blade to crush and crush the hard crushed material at the part, and cut the soft crushed material at the other part of the first rotating shaft and the part facing the second rotating shaft and the second rotating shaft In addition to attaching a cutting blade to be crushed, a hopper for supplying a hard crushed material is provided above the crushing blade, and a hopper for supplying a soft crushed material is provided above the cutting blade.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an apparatus for sorting and crushing medical waste and the like according to the present invention will be described with reference to an embodiment. 1 is a vertical sectional front view showing the entire structure, FIG. 2 is a cross-sectional view taken along the line XX shown in FIG. 1, FIG. 3 is a cross-sectional view taken along the line YY shown in FIG. The left and right three intermediate bearing plates 3 disposed at the upper part of the first bearing plate 3 are rotatably supported by the left and right bearing plates 2a and 2c, and the first long rotating shaft 4 is intermediate with the left bearing plate 2c. A second rotating shaft that is rotatably supported by the bearing plate 2b.
[0009]
Reference numeral 5 denotes a portion where the second rotating shaft 4 does not face, and is a hook-shaped crushing blade which is attached to the first rotating shaft 3 at intervals. The crushing blade 5 receives a hard crushed material Wa such as a glass container. 6 and crush-crush it. Reference numeral 7 denotes a casing provided so as to surround the crushing blade 5 and the receiving blade 6, reference numeral 8 denotes a hopper 9 for inputting crushed material Wa provided above the crushing blade 5, and a discharge cylinder provided below the casing 7.
[0010]
10a is a saw blade-shaped cutting blade attached to the second rotating shaft 4 at intervals. 10b is a saw blade-shaped cutting blade attached to the portion of the first rotating shaft 3 facing the rotating shaft 4. It is. The cutting blades 10a and 10b rotate in directions opposite to each other, and crush the soft crushed material Wb such as a resin bag. Reference numeral 11 denotes a casing provided so as to surround the cutting blades 10a and 10b. Reference numeral 11 denotes a hopper 13 provided above the cutting blades 10a and 10b for charging the crushed material Wb.
[0011]
The first rotating shaft 3 and the second rotating shaft 4 are rotationally driven by a drive motor 14 via transmission means such as sprockets and gears. The speed ratio between the first rotating shaft 3 and the second rotating shaft 4 is set to 1: 4.
[0012]
Since the configuration of the apparatus for separating and crushing medical waste according to one embodiment is as described above, when the waste is a glass container, porcelain, or the like, the waste is put into the right hopper 8. The supplied hard crushed material Wa is pressed by the receiving blade 6 by the claw-shaped crushing blade 5 and crushed. The crushed pieces fall down from the discharge cylinder 9.
[0013]
When the waste is a resin container, a tube, or the like, the waste is put into the hopper 12 on the left side. The supplied soft crushed material Wb is cut by the pair of cutting blades 10a and 10b. Since the cutting blades 10a and 10b have a saw blade shape, they are completely finely cut without entanglement. Then, the finely crushed pieces fall downward from the discharge cylinder 13.
[0014]
The waste crushed into small pieces as described above can be compactly stored in a storage box (not shown) provided below the discharge tubes 9 and 13. In the case where the volume is reduced in this way, it is possible to greatly reduce the labor and cost of post-processing.
[0015]
【The invention's effect】
Thus, according to the apparatus for separating and crushing medical waste and the like according to the present invention, hard crushed materials such as glass containers and soft crushed materials such as resin containers can be separated and crushed. Therefore, an excellent effect of being able to rationally reduce the volume of various medical wastes is exhibited.
