Description
【０００１】
【産業上の利用分野】
本発明は、ガラス廃材とプラスチック廃材とより成形する人工軽量骨材の製造方法に関する。
【０００２】
【従来の技術】
ガラス廃材やプラスチック廃材は産業廃棄物や都市ごみとして大量に廃棄されるようになり、プラスチックはその熱容量や発生する有毒ガスのために安易に焼却処理をすることができず、またガラス廃材も焼却処理ができないため埋立地に投棄されるのが一般的である。
【０００３】
【発明が解決しようとする課題】
しかしながら、これらの廃材を埋め立て処理するにしても嵩が高いために広い埋め立て地を確保する必要がある。
【０００４】
したがって、これらの廃棄物を減容処理する方法や再利用の方法が種々模索されている。
【０００５】
本発明は上記の点に鑑み、これらの廃棄物を減容すると共に再利用を可能とした人工軽量骨材の製造方法を提供することを目的とする。
【０００６】
【問題を解決するための手段】
本発明は上記の目的を達成するために、ガラス廃材とプラスチック廃材とを破砕機にてそれぞれ所定の大きさに破砕し、これら破砕したガラス廃材とプラスチック廃材とをミキサにて混合した後、このガラス廃材とプラスチック廃材との混合物をドライヤにて加熱し、溶融させたプラスチック廃材をバインダーとして破砕したガラス廃材を互いに凝集させていって所定の大きさの塊にして造粒し、ガラス廃材とプラスチック廃材とより成る軽量骨材を形成するようにしたことを特徴としている。
【０００７】
【作用】
本発明の人工軽量骨材の製造方法によれば、ガラス廃材とプラスチック廃材とを破砕機にてそれぞれ所定の大きさに破砕し、これら破砕したガラス廃材とプラスチック廃材とをミキサにて混合した後、このガラス廃材とプラスチック廃材との混合物をドライヤにて加熱することにより、プラスチック廃材のうち熱可塑性プラスチックが溶融し、この溶融したプラスチック成分が周囲に散在するガラス廃材の間に介在してバインダーとなり、ガラス廃材を互いに凝集させて所定の大きさの塊にしてガラス廃材を造粒し、人工軽量骨材を成形するのである。
【０００８】
【実施例】
以下本発明の実施例を図面に基づいて説明する。
【０００９】
１はガラス廃材用ホッパであって、収集したガラス廃材を一時貯留する。ガラス廃材用ホッパ１より払い出したガラス廃材は下位に配設した一次破砕機２により粗砕し、更に二次破砕機３に送り込んで３ｍｍ〜１５ｍｍ程度に破砕する。そして破砕したガラス廃材はガラス貯蔵ビン４に貯蔵しておく。
【００１０】
５はプラスチック廃材用ホッパであって、収集したプラスチックス廃材を一時貯留する。プラスチック廃材用ホッパ５より払い出したプラスチック廃材は下位に配設した一次破砕機６により粗砕し、更に二次破砕機７に送り込んで細かく破砕する。そして破砕したプラスチック廃材はプラスチック貯蔵ビン８に貯蔵しておく。
【００１１】
ガラス貯蔵ビン４及びプラスチック貯蔵ビン８より払い出したガラス廃材とプラスチック廃材とは下位に配設したミキサ９に投入され、回転軸の周囲に多数の配設された混合羽根により混合される。
【００１２】
混合されたガラス廃材とプラスチック廃材はミキサ９の下流に配設されたドライヤ１０に送り込まれる。ドライヤ１０は円筒状のドラムを回転自在に傾斜支持したもので、送り込まれたガラス廃材とプラスチック廃材はドラム内を転動流下する間にドラムの一端部に配設されたバーナ１１より送り込まれる熱風により加熱される。
【００１３】
加熱する熱風はプラスチック廃材が溶融する２００℃〜６００℃程度の温度に設定されており、ドラム１１内でガラス廃材とプラスチック廃材が加熱されるとプラスチック廃材が溶融してガラス廃材の表面に付着すると共に、ガラス廃材同士を接着させてガラス廃材を造粒するようになる。
【００１４】
このように加熱されて造粒されたガラス廃材はドライヤ１０より排出されて冷却されて人工軽量骨材とされるのである。
【００１５】
こうして製造された人工軽量骨材は、道路舗装の路盤材等の土木、建築材料としての利用や、他の産業での利用が期待できてガラス廃材及びプラスチック廃材の再利用の途が広げることができる。
【００１６】
なお、プラスチックには、ポリエチレン、ポリプロピレン、ポリ塩化ビニールといった熱硬化性樹脂やフェノール樹脂、尿素樹脂といった熱硬化性樹脂があり、プラスチック廃材にはこれらのプラスチックが混在する場合が多く、その剛性や粘性、あるいは温度に対する軟化度、溶融度といった性状は多様で、破砕や加熱といった操作を安定的に行なうためには分別収集してできるだけ使用する樹脂の純度を高めるのが好ましい。
【００１７】
また、これらプラスチックは加熱すると有害ガスを発生するものもあり、加熱温度はできるだけ低い温度、例えば３００℃以下に押えるのが好ましい。
【００１８】
また、プラスチック廃材の粒度を細かくすることによりガラス表面へのコーティングを行なうことも可能であり、非透水性の人工軽量骨材の形成も可能である。
【００１９】
【発明の効果】
以上のように本発明に係る人工軽量骨材の製造方法にあっては、ガラス廃材とプラスチック廃材とを破砕機にてそれぞれ所定の大きさに破砕し、これら破砕したガラス廃材とプラスチック廃材とをミキサにて混合した後、このガラス廃材とプラスチック廃材との混合物をドライヤにて加熱し、溶融させたプラスチック廃材をバインダーとして破砕したガラス廃材を互いに凝集させていって所定の大きさの塊にして造粒して軽量骨材を形成するので、ガラス廃材及びプラスチック廃材の減容化を図ることができる。
【００２０】
またこうして製造された人工軽量骨材は、道路舗装の路盤材やコンクリートブロック等の土木、建築材料としての利用や、他の産業での利用が期待できてガラス廃材及びプラスチック廃材の再利用の途を広げることができる。

[Industrial applications]
The present invention relates to a method for producing an artificial lightweight aggregate formed from waste glass and waste plastic.
[0002]
[Prior art]
Glass waste and plastic waste are being disposed of in large quantities as industrial waste and municipal waste.Plastic cannot be easily incinerated due to its heat capacity and toxic gas generated, and glass waste is also incinerated. Because they cannot be treated, they are generally dumped in landfills.
[0003]
[Problems to be solved by the invention]
However, even if these waste materials are landfilled, it is necessary to secure a wide landfill because the bulk is high.
[0004]
Therefore, various methods of reducing the volume of these wastes and methods of reusing them have been sought.
[0005]
In view of the above, an object of the present invention is to provide a method for producing an artificial lightweight aggregate that can reduce the volume of these wastes and enable reuse.
[0006]
[Means to solve the problem]
For the present invention to achieve the above object, after crushing the respective predetermined size in glass waste and plastic waste and the crusher was mixed with these crushed glass waste and plastic waste was in a mixer, The mixture of the glass waste material and the plastic waste material is heated by a dryer, and the crushed glass waste material is aggregated with each other by using the melted plastic waste material as a binder, and granulated into a lump having a predetermined size. It is characterized in that a lightweight aggregate made of plastic waste material is formed.
[0007]
[Action]
According to the process for producing an artificial lightweight aggregate of the present invention, broken into each predetermined size in glass waste and plastic waste and the crusher, and these crushed glass waste and plastic waste was mixed with a mixer Then, by heating the mixture of the glass waste material and the plastic waste material with a dryer , the thermoplastic plastic in the plastic waste material is melted, and the molten plastic component is interposed between the glass waste materials scattered around and the binder. Then, the glass waste materials are aggregated with each other to form a lump having a predetermined size, and the glass waste materials are granulated to form an artificial lightweight aggregate.
[0008]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The artificial lightweight aggregate manufactured in this way can be expected to be used as civil engineering and building materials for roadbed pavement, etc., and used in other industries, and the reuse of glass waste and plastic waste can be expanded. it can.
[0016]
Plastics include thermosetting resins such as polyethylene, polypropylene and polyvinyl chloride, and thermosetting resins such as phenolic and urea resins. These plastics are often mixed with plastic waste, and their rigidity and viscosity are high. In addition, properties such as softening degree and melting degree with respect to temperature are various, and in order to stably perform operations such as crushing and heating, it is preferable to increase the purity of the resin used by separating and collecting as much as possible.
[0017]
In addition, some of these plastics generate harmful gases when heated, and it is preferable that the heating temperature be kept as low as possible, for example, 300 ° C. or less.
[0018]
Further, it is possible to coat the glass surface by reducing the particle size of the plastic waste material, and it is also possible to form a water-impermeable artificial lightweight aggregate.
[0019]
【The invention's effect】
In the process for producing an artificial lightweight aggregate according to the present invention as described above, respectively in glass waste and plastic waste and the crusher crushed to a predetermined size, and these crushed glass waste and plastic waste was After mixing with a mixer, the mixture of the glass waste material and the plastic waste material is heated by a dryer, and the crushed glass waste material is agglomerated with each other using the melted plastic waste material as a binder to form a predetermined size lump. Since a lightweight aggregate is formed by granulation, waste glass and plastic waste can be reduced in volume.
[0020]
The artificial lightweight aggregate produced in this way is expected to be used as civil engineering and building materials such as roadbed materials for road pavement and concrete blocks, as well as in other industries. Can be expanded.
