【発明の属する技術分野】
本発明は、廃発泡スチレン樹脂（以下、廃発泡スチロールと略す）を処理液（減容化液）で減容化する廃発泡スチロールの処理装置に関する。
【０００２】
【従来の技術】
発泡スチロールは各種包装材として広く利用されているが、その容積の９０％以上が気体であるため、廃棄されたときその運搬処理に多大な費用を要する欠点がある。
そこでその廃発泡スチロールを減容化液によって減容する装置が、各種提案されている（例えば、特許文献１参照。）。
【０００３】
【特許文献１】
特開平１１−１７９７２７号
【０００４】
特許文献１の「廃棄発泡スチロールの減容方法及び廃棄発泡スチロールの減容装置」は、廃発泡スチロールを破砕及び粉砕する装置と、その下流側に設けた減容容器と、その内部に設けられた羽根板を有する回転体とを具備し、容器内に１２０℃〜２４０℃程度の液状熱媒体（減容化液）を容器の半分以上満たすように収納したものである。そして容器内に粉砕された廃発泡スチロールを投入し、羽根板を有する回転体を回転させることにより、廃発泡スチロールと液状熱媒体とを攪拌して廃発泡スチロールを減容化し、次いで減容化された処理体を減容容器から外部に取り出し、次いで減容化の為に消費した分だけ液状熱媒体を減容容器内に補充し、新たな廃発泡スチロールを減容容器に投入し、前記同様に減容化するものである。
【０００５】
【発明が解決しようとする課題】
このような減容容器は、大量の液状熱媒体が満たされ、それに粉砕された廃発泡スチロールとを混合して減容化し、その減容の進行に伴って処理された処理体を外部に排出するものである。次いで、減容化のために消費された分だけ液状熱媒体を補充し、同様の工程で次の廃発泡スチロールの処理を行なうものである。ところが、実験によれば減容液である液状熱媒体は、次第に劣化し、減容能力が低下するものとなる。そこで、減容状態を時々点検しながら、液状熱媒体を全量交換しなければならない面倒があった。また、大きな減容容器を必要とし、装置全体が大型化する欠点があった。
【０００６】
また、処理体を外部に円滑に排出するためには、少量の減容液を処理体と共に排出する必要があるものの、従来の装置では、その処理体の排出にともない必要以上の多量の液状熱媒体（減容液）が流れ出されてしまう。そのため液状熱媒体の消費量が多く、ランニングコストが高くなる欠点があった。
そこで、上記欠点を解消するため、コンパクトで必要最小限の減容化液で、廃発泡スチロールを減容化できる廃発泡スチロールの処理装置を提供することを課題とする。
【０００７】
【課題を解決するための手段】
請求項１に記載の本発明は、軸線が斜め上方に向けられた円筒状のシリンダ（１）と、
そのシリンダ（１）の下端部に設けられ、破砕された廃発泡スチロールの入口（２）と、
そのシリンダ（１）の上端部に設けられ、餅状に処理された廃発泡スチロールの出口（３）と、
そのシリンダ（１）の外周に設けられた加温手段（４）と、

を具備し、前記シリンダ（１）の下部に減容化液（６）が蓄えられ、
前記螺旋翼（５）の回転駆動と減容化液（６）により、廃発泡スチロールが餅状に減容化され、それが前記シリンダ（１）内を上昇して、そのシリンダ（１）上端部の前記出口（３）より排出されると共に、シリンダ（１）内を上昇する廃発泡スチロールに含まれる減容液（６）はシリンダ（１）の下部に流下して、新たな廃発泡スチロールの減容化に使用されるように構成された廃発泡スチロールの処理装置である。
【０００８】
請求項２に記載の本発明は、請求項１において、前記処理体の出口（３）が、シリンダ（１）の外周に形成され、その出口（３）より上方の前記螺旋翼（５）の螺旋方向は、下方側のそれとは逆向きに形成され且つ、その下方側の螺旋翼（５）の上端と、出口（３）より上方の螺旋翼の下端との間に空間を有し、その空間に餅状の廃発泡スチロールを排出する取出片（１８）が設けられた廃発泡スチロールの処理装置である。
【０００９】
【発明の実施の形態】
次に、図面に基づいて本発明の実施の形態につき説明する。
図１は本発明の廃発泡スチロールの処理装置の要部縦断面図であり、図２は図１のII−II矢視断面略図である。また、図３はシリンダ１の出口３の近傍における内部の平面的断面図、図４は同正面図である。
この処理装置は、図１に示す如く、温水のジャケットを構成するタンク７と、タンク７内に軸線が斜め上方に向けられた円筒状のシリンダ１と、シリンダ１に内装された螺旋翼５とを有する。
【００１０】
シリンダ１の下端部外周には、破砕された廃発泡スチロールが投入される入口２が設けられ、シリンダ１の上端部外周には処理体の出口３が設けられている。そしてシリンダ１の軸線上に軸16が内装され、その上下両端が軸受12によって支持されている。軸16の外周には、螺旋翼５が設けられている。この螺旋翼５は、出口３の中心を境に上部側の螺旋方向が下部側のそれと逆向きに形成されている。軸16の上端にはスプロケット10が固定され、それとモータ８のスプロケット10との間がチエーン９で連結されている。
【００１１】
シリンダ１の下部には減容液パイプ17が突設され、そこから必要最小限の減容化液６がシリンダ１の内部に供給される。また、タンク７内には加温手段４であるヒータ11が配置され、タンク７内の水を一例として８０℃程度の温水にしシリンダ１の外周を加温する。
また、出口３内には図３及び図４に示す如く取出片18が配置されている。
【００１２】
なお、減容化液６（処理液）としては各種公知のものが使用できる。一例として、Ａ重油，廃エンジンオイルまたは灯油を主剤とし、これに環状ケトンが配合された処理液を用いることができる。そしてその環状ケトンとしては、シクロペンタノン，シクロエキサノン，シクロヘプタノンまたはシクロオクタノンとすることができる。また、Ａ重油等の主剤と環状ケトンとの配合割合は、主剤１００に対し環状ケトンを３〜５０重量％とすることができる。なお、上記処理液に代えてリモネンを処理液として使用することも可能である。
【００１３】
【使用方法】
先ず、前記の如く、シリンダ１の下部の減容液パイプ17から必要最小限の減容化液６をシリンダ１の内部に供給する。その減容化液６は、シリンダの下部に溜まる。そして、ヒータ11を加熱してタンク７内の水を加温する。次いで、図示しない廃発泡スチロールの破砕装置によってポップコーン状に破砕された廃発泡スチロールが入口２から投入される。それと共に、モータ８を駆動し軸16及び螺旋翼５を回転させと、その螺旋翼５が投入された廃発泡スチロールと減容化液６とを攪拌する。
【００１４】
するとその廃発泡スチロールは次第に柔らかい餅状に流動化され、螺旋翼５により下部から上方に次第に搬送される。処理体は回転軸の回りにからみつき、減容化液６はその処理体と螺旋翼の回りとの空間を螺旋状に流下し、あるいはその螺旋翼５の外周とシリンダ１の内周との間の隙間を通って、減容化液６は下方に移動し、常に下部に溜めれる。そして、廃発泡スチロールの処理体は、僅かの減容化液６を内部および外周に含んで出口３から流出する。
【００１５】
このとき、出口３の近傍では、その中心より上方側の螺旋翼５は下方側とは逆向きに形成されているため、より上方に移動した処理体は出口３側に引き戻される。また、下方側にある処理体は上方側に移動し、それらが取出片18によって軸16及び螺旋翼５から分離されて出口３より外部に排出される。
シリンダ１の下部に必要最小限の減容化液６を供給することにより、減容化に寄与しある程度劣化した液は、処理体と共に殆ど全て外部に排出することができる。
【００１６】
【発明の作用・効果】
本発明の廃発泡スチロールの処理装置は、シリンダ１の軸線が斜め上方に向けられ、そこに螺旋翼５が内装され、シリンダ１の下端部に廃発泡スチロールの入口２が設けられ、上端部に餅状に処理された廃発泡スチロールの出口３が設けられたものである。そしてシリンダ１の下部に減容化液６が蓄えられ、螺旋翼５を回転駆動することにより廃発泡スチロールを軸線方向上方に向けて搬送するように構成し、餅状の廃発泡スチロールがシリンダ１上端部の前記出口３より排出されると共に、シリンダ１内を上昇する廃発泡スチロールに含まれる減容化液６はシリンダ１の下部に流下して、廃発泡スチロールの減容化に再使用されるように構成されたものである。そして、シリンダ１に減容化液を供給する減容液パイプ１７が連通されたものである。
このように構成することにより、処理装置をコンパクトに形成できる。それと共に、シリンダ１の下部に溜められる減容化液を必要最小限にしても減容化が可能となる。そして減容化された廃発泡スチロールに含まれる余分な減容化液は、自然に下方に流下し常にシリンダ１の下部に戻され、新たな廃発泡スチロールを減容化する。そして減容化液６の消費を必要最小限に抑え、そのランニングコストを低下させることができる。
【００１７】
上記構成において、出口３より上方の螺旋翼５の螺旋方向を下方側のそれとは逆向きに且つ、その下方側の螺旋翼５の上端と、出口３より上方の螺旋翼の下端との間に空間を有し、その空間に餅状の廃発泡スチロールを排出する取出片１８を設けることができる。その場合には、出口３より上方に存在する処理体を出口３側に引き戻してそれを外部に円滑に排出することができる。このとき、上記空間および取出片１８の存在により、出口３の上流側の餅状廃発泡スチロールと下流側のそれとが干渉することなく、出口３から円滑に排出される。
上記構成において、シリンダ１の外周に温水等の加温流体が充満するタンク７を被嵌することができる。その場合は、温度管理が容易となり迅速に減容化できる信頼性の高い処理装置を提供できる。

BACKGROUND OF THE INVENTION
The present invention relates to a waste foamed styrene treatment apparatus for reducing the volume of waste foamed styrene resin (hereinafter abbreviated as waste foamed polystyrene) with a treatment liquid (volume reduction liquid).
[0002]
[Prior art]
Styrofoam is widely used as various packaging materials, but 90% or more of its volume is a gas, so that it has a drawback of requiring a large amount of cost for its transportation treatment when discarded.
Therefore, various devices for reducing the volume of the waste expanded polystyrene with a volume reducing liquid have been proposed (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 11-179727
Patent Document 1 “Volume reduction method of waste foamed polystyrene and volume reduction device of waste foamed polystyrene” includes a device for crushing and pulverizing waste foamed polystyrene, a volume reduction container provided on the downstream side thereof, and a blade plate provided in the inside thereof. The liquid heat medium (volume reduction liquid) of about 120 ° C. to 240 ° C. is stored in the container so as to fill more than half of the container. Then, the waste foamed polystyrene is put into the container, and the rotating foam having the blades is rotated to agitate the waste foamed polystyrene and the liquid heat medium to reduce the volume of the waste foamed polystyrene, and then the volume-reduced treatment.

Such a volume reduction container is filled with a large amount of liquid heat medium, mixed with pulverized waste expanded polystyrene to reduce the volume, and discharges the processed body to the outside as the volume reduction progresses. Is. Next, the liquid heat medium is replenished by the amount consumed for volume reduction, and the next waste polystyrene foam is treated in the same process. However, according to the experiment, the liquid heat medium that is a volume reducing liquid gradually deteriorates and the volume reducing capacity is lowered. Therefore, there is a trouble that the entire amount of the liquid heat medium must be replaced while checking the volume reduction state from time to time. In addition, there is a disadvantage that a large volume reduction container is required and the entire apparatus is enlarged.

In addition, in order to smoothly discharge the processing body to the outside, it is necessary to discharge a small volume of the volume reducing liquid together with the processing body. The medium (volume reduction liquid) will flow out. For this reason, there is a disadvantage that the consumption of the liquid heat medium is large and the running cost is high.
Then, in order to eliminate the said fault, it makes it a subject to provide the processing apparatus of the waste expanded polystyrene which can reduce a volume of a waste expanded polystyrene with the volume reduction liquid of the minimum required.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a longitudinal sectional view of a main part of a processing apparatus for waste foamed polystyrene according to the present invention, and FIG. 2 is a schematic sectional view taken along the line II-II in FIG. 3 is a plan sectional view of the inside of the cylinder 1 in the vicinity of the outlet 3, and FIG. 4 is a front view of the same.
As shown in FIG. 1, this processing apparatus includes a tank 7 constituting a jacket for hot water, a cylindrical cylinder 1 whose axis is directed obliquely upward in the tank 7, and a spiral blade 5 housed in the cylinder 1. Have
[0010]
On the outer periphery of the lower end portion of the cylinder 1, an inlet 2 into which the crushed waste foamed polystyrene is introduced is provided, and on the outer periphery of the upper end portion of the cylinder 1, an outlet 3 of the processing body is provided. A shaft 16 is housed on the axis of the cylinder 1, and its upper and lower ends are supported by bearings 12. A spiral wing 5 is provided on the outer periphery of the shaft 16. The spiral blade 5 is formed such that the spiral direction on the upper side is opposite to that on the lower side with respect to the center of the outlet 3. A sprocket 10 is fixed to the upper end of the shaft 16, and the sprocket 10 of the motor 8 is connected by a chain 9.
[0011]
A volume-reducing liquid pipe 17 projects from the lower part of the cylinder 1, and the minimum volume-reducing liquid 6 is supplied into the cylinder 1 from there. In addition, a heater 11 which is a heating means 4 is disposed in the tank 7, and the outer periphery of the cylinder 1 is heated to a temperature of about 80 ° C. as an example.
Further, an extraction piece 18 is disposed in the outlet 3 as shown in FIGS.
[0012]
In addition, various well-known things can be used as the volume reducing liquid 6 (processing liquid). As an example, a treatment liquid containing A heavy oil, waste engine oil, or kerosene as a main agent and a cyclic ketone added thereto can be used. The cyclic ketone can be cyclopentanone, cycloexanone, cycloheptanone or cyclooctanone. Moreover, the compounding ratio of the main agent such as A heavy oil and the cyclic ketone can be 3 to 50% by weight of the cyclic ketone with respect to the main agent 100. In addition, limonene can be used as the treatment liquid instead of the treatment liquid.
[0013]
【how to use】
First, as described above, the necessary minimum volume reducing liquid 6 is supplied into the cylinder 1 from the volume reducing liquid pipe 17 below the cylinder 1. The volume reducing liquid 6 accumulates in the lower part of the cylinder. And the heater 11 is heated and the water in the tank 7 is heated. Next, waste foam polystyrene crushed into popcorn by a waste foam polystyrene crusher (not shown) is introduced from the inlet 2. At the same time, when the motor 8 is driven to rotate the shaft 16 and the spiral blade 5, the waste foamed polystyrene and the volume reducing liquid 6 into which the spiral blade 5 has been charged are stirred.
[0014]
Then, the waste expanded polystyrene is gradually fluidized in a soft bowl shape and is gradually conveyed upward from the lower portion by the spiral blade 5. The treatment body is entangled around the rotation axis, and the volume reducing liquid 6 flows down spirally in the space between the treatment body and the spiral blade, or between the outer periphery of the spiral blade 5 and the inner periphery of the cylinder 1. Through this gap, the volume reducing liquid 6 moves downward and is always stored in the lower part. And the waste polystyrene processing body contains the slight volume reducing liquid 6 in the inside and the outer periphery and flows out from the outlet 3.
[0015]
At this time, in the vicinity of the outlet 3, the spiral blade 5 above the center is formed in the opposite direction to the lower side, so that the treatment body that has moved further upward is pulled back to the outlet 3 side. The processing body on the lower side moves upward, and is separated from the shaft 16 and the spiral blade 5 by the take-out piece 18 and discharged to the outside from the outlet 3.
By supplying the necessary minimum volume reducing liquid 6 to the lower part of the cylinder 1, almost all of the liquid that has contributed to volume reduction and has deteriorated to some extent can be discharged to the outside together with the processing body.
[0016]

The volume reduction solution 6 is stored in the lower portion of the cylinder 1, the waste foamed polystyrene configured to convey toward axially upward by rotating the helical blade 5, dough waste polystyrene foam cylinder 1 upper portion The volume reducing liquid 6 discharged from the outlet 3 and contained in the waste foamed polystyrene rising in the cylinder 1 flows down to the lower part of the cylinder 1 and is reused for volume reduction of the waste foamed polystyrene. It has been done . A volume reducing liquid pipe 17 for supplying the volume reducing liquid to the cylinder 1 is communicated.
By comprising in this way, a processing apparatus can be formed compactly. At the same time, the volume can be reduced even if the volume reducing liquid stored in the lower part of the cylinder 1 is minimized. The excess volume reducing liquid contained in the volume-reduced waste foamed polystyrene naturally flows downward and is always returned to the lower part of the cylinder 1 to reduce the volume of new waste foamed polystyrene. And consumption of the volume reducing liquid 6 can be suppressed to the necessary minimum, and the running cost can be reduced.
[0017]
In the above configuration, the spiral direction of the spiral blade 5 above the outlet 3 is opposite to that on the lower side and between the upper end of the lower spiral blade 5 and the lower end of the spiral blade above the outlet 3. a space, a take-out piece 18 for discharging the dough-like waste polystyrene foam provided it is Rukoto in the space. In that case, the processing body existing above the outlet 3 can be pulled back to the outlet 3 side and discharged smoothly to the outside. At this time, due to the presence of the space and the take-out piece 18, the waste-like foamed polystyrene on the upstream side of the outlet 3 and the downstream one are smoothly discharged from the outlet 3 without interference.
