【発明の属する技術分野】
本発明は、廃棄用の廃ドラム缶を処理して再資源化する廃ドラム缶の再資源化システムに関するものである。
【0002】
【従来の技術】
ドラム缶は、液体や固体の廃棄物など種々のものを保管したり運搬したりする際に広く使用されている。また、その用途別によって、蓋付き缶や蓋なし缶、あるいは構成材料により種々のものが実用化されている。
【0003】
従来、このようなドラム缶は腐食などにより使用回数や使用期間に制限がある場合が多く、また収容物が異なると使用できない場合もある。
【0004】
【発明が解決しようとする課題】
ところで、従来では使用済みの廃ドラム缶はそのまま廃棄処分されることが多く、資源の再利用化が図られていないという問題点があった。
【0005】
本発明は、上記のような問題点に着目してなされたもので、使用済みの廃ドラム缶を容易に再資源化することができ、貴重な資源を無駄にすることのない廃ドラム缶の再資源化システムを提供することを目的としている。
【0006】
【課題を解決するための手段】
本発明に係るドラム缶の再資源システムは、廃棄用のドラム缶を再資源化する再資源化システムであって、廃ドラム缶を破砕するシュレッダーと、破砕された各断片を500〜600℃の温度で加熱する加熱手段と、加熱後の各断片を粒状のペレットにする造粒機と、振動スクリーンとを備え、かつ前記造粒機で得られるペレットを、振動スクリーンにより粒状のスチールペレットと粉状のスチール材料とを分離し、夫々各別の容器に収容して成るものである。
【0008】
【発明の実施の形態】
図1は本発明の一実施例による廃ドラム缶の再資源化システムの構成を示すブロック図である。
【0009】
同図において、1は使用済みの廃ドラム缶が投入される投入口、2は投入された廃ドラム缶を破砕する上下2段式の4軸シュレッダー、3は破砕された各断片を所定温度で加熱するロータリーキルン(加熱手段)、4は加熱後の各断片を粒状のペレットにする造粒機、5は該ペレットから粉状のスチール材料を分離する振動スクリーンで、粒状のスチールペレットは容器6に、粉状のスチール材料は容器7にそれぞれ収容される。
【0010】
また、8はロータリーキルン3に設けられた二次燃焼炉で、この二次燃焼炉8の先には排ガス冷却装置9、サイクロン10、集塵機11、排風機12及びサイレンサー13が順次接続されている。
【0011】
次に、上記システムの処理の流れについて図2の工程図により詳細に説明する。
【0012】
まず、投入口1から投入された廃ドラム缶は上下2段式の4軸シュレッダー2に送り込まれ、このシュレッダー2の上部で粗破砕されてから下部で更に細かく破砕される(S1)。次に、この破砕された各断片は、回転式のロータリーキルン3により500°〜600℃の温度で加熱され(S2)、これにより塗料や残留物等が燃焼され、その排ガスは二次燃焼炉8に入る。
【0013】
上記ロータリーキルン3で加熱された各断片は造粒機4に送られ、ここで粒状のペレットに形成される(S3)。このペレットは更に振動スクリーン5に送り込まれ、粉状のスチール材料が分離されて取り出される(S4)。そして、粒状のスチールペレットは容器6、粉状のスチール材料は容器7にそれぞれ収容される。
【0014】
このようにして、使用済みの廃ドラム缶を容易に再資源化することができるので、貴重な資源を無駄にすることはない。
【0015】
一方、ロータリーキルン3に設けられた二次燃焼炉8での燃焼物(排ガス)は、冷却装置9によって冷却され、サイクロン10及び集塵機11を通って除塵された後、排風機12により大気中に放出される。このとき、サイレンサー13によって騒音の発生が抑制される。
【0016】
【発明の効果】
以上のように、本発明によれば、廃棄用のドラム缶を容易に再資源化することができ、貴重な資源を無駄にすることがないという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a waste drum can recycling system for processing and recycling waste drum cans for disposal.
[0002]
[Prior art]
Drums are widely used for storing and transporting various things such as liquid and solid waste. Depending on the application, various types of cans with lids, cans without lids, or constituent materials have been put into practical use.
[0003]
Conventionally, such drums are often limited in the number of times and the period of use due to corrosion or the like, and may not be used if the contents are different.
[0004]
[Problems to be solved by the invention]
Conventionally, used waste drums are often discarded as they are, and there is a problem that resources are not reused.
[0005]
The present invention has been made paying attention to the above-mentioned problems, and can easily recycle used waste drums and can recycle waste drums without wasting valuable resources. The purpose is to provide an integrated system.
[0006]
[Means for Solving the Problems]
The drum can recycling system according to the present invention is a recycling system for recycling drum drums for disposal, in which shredders for crushing waste drum cans and each crushed piece are heated at a temperature of 500 to 600 ° C. Heating means, a granulator for making each piece after heating into granular pellets, and a vibrating screen, and the pellets obtained by the granulator are made into granular steel pellets and powdered steel by a vibrating screen The material is separated and accommodated in a separate container.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing the configuration of a waste drum can recycling system according to an embodiment of the present invention.
[0009]
In the same figure, 1 is an inlet into which a used waste drum can is charged, 2 is an upper and lower two-stage four-axis shredder that crushes the thrown waste drum can, and 3 is a crushed piece heated at a predetermined temperature. A rotary kiln (heating means), 4 is a granulator for making each piece after heating into granular pellets, 5 is a vibrating screen for separating the powdered steel material from the pellets, and the granular steel pellets are put into the container 6 Each steel material is accommodated in a container 7.
