本発明は例えば高分子を含む一般都市廃棄物や事業所等から排出される廃棄プラスチック等の産業廃棄物等の被処理物を圧縮、減容、固化する際に用いられる二軸スクリュウ式押出成型機に関するものである。   The present invention is, for example, a biaxial screw type extrusion molding used for compressing, reducing, and solidifying an object to be treated such as a general city waste containing a polymer and an industrial waste such as a waste plastic discharged from a business office. Related to the machine.

従来この種の二軸スクリュウ式押出成型機として、一方側部に被処理物の投入部を設けると共に他方側部に排出部を設けてなるケーシングと、ケーシング内にその螺旋状の羽根部が互いに重なり合った状態で回転自在に並設された一対のスクリュウ軸と、一対のスクリュウ軸を咬合方向に回転させる駆動機構と、ケーシングの排出部に設けられ、一対のスクリュウ軸の咬合回転により混練圧縮移送されてくる被処理物を排出する複数個の排出口部をもつダイスプレートとからなる構造のものが知られている。

Japanese Patent No. 3921614

しかしながら上記従来構造の場合、上記被処理物は一対のスクリュウ軸の咬合回転により上記ケーシングの内周面と上記羽根部とにより形成された移送空間で混練圧縮移送されながら上記ダイスプレートの複数個の排出口部より排出され、このとき、被処理物は上記ケーシングの内周面に圧摺接され、被処理物が各種の廃棄物であることも相俟って、被処理物の圧摺接によりケーシングの内面の摩耗が激しく、そして、過度に摩耗損傷したときには、新たなケーシングに取り替えたり、摩耗したケーシングの内周面に肉盛補修をして対処しなければならず、これらの対処により被処理物の処理能率の低下を招くことがあると共にケーシングは製作コストが高く、それだけ、経済性に劣ることがあるという不都合を有している。   However, in the case of the conventional structure, the object to be processed is kneaded and compressed and transferred in the transfer space formed by the inner peripheral surface of the casing and the blades by the occlusal rotation of a pair of screw shafts. At this time, the object to be processed is slidably contacted with the inner peripheral surface of the casing, and the object to be processed is slidable in contact with various wastes. If the wear on the inner surface of the casing is severe and excessive wear damage occurs, it must be replaced with a new casing or the inner peripheral surface of the worn casing must be repaired. The processing efficiency of the object to be processed may be reduced, and the casing has a disadvantage that the manufacturing cost is high and the cost is inferior.

本発明はこれらの不都合を解決することを目的とするもので、本発明のうちで、請求項１記載の発明は、一方側部に被処理物の投入部を設けると共に他方側部に排出部を設けてなるケーシングと、該ケーシング内にその螺旋状の羽根部が互いに重なり合った状態で回転自在に並設された一対のスクリュウ軸と、該一対のスクリュウ軸を咬合方向に回転させる駆動機構と、該ケーシングの排出部に設けられ、該一対のスクリュウ軸の咬合回転により混練圧縮移送されてくる被処理物を排出する複数個の排出口部をもつダイスプレートとからなり、上記ケーシングの内周面に上記一対のスクリュウ軸の羽根部とにより移送空間を形成するバレルライナーを交換自在に設けてなることを特徴とする二軸スクリュウ式押出成型機にある。   The present invention aims to solve these disadvantages. Among the present inventions, the invention according to claim 1 is characterized in that an input portion for a workpiece is provided on one side and a discharge portion is provided on the other side. A pair of screw shafts that are rotatably arranged in a state where the spiral blade portions overlap each other in the casing, and a drive mechanism that rotates the pair of screw shafts in an occlusal direction. And a die plate having a plurality of discharge ports for discharging the object to be processed which is kneaded and compressed by the occlusal rotation of the pair of screw shafts. A twin-screw extruder is characterized in that a barrel liner that forms a transfer space is exchangeably provided on the surface by the blade portions of the pair of screw shafts.

又、請求項２記載の発明は、上記ケーシングにその先端部が上記バレルライナーの内周面に露呈する検出部材を着脱自在に設けてなることを特徴とするものであり、又、請求項３記載の発明は、上記検出部材は検出ボルトであることを特徴とするものである。   The invention according to claim 2 is characterized in that a detection member whose tip is exposed on the inner peripheral surface of the barrel liner is detachably provided on the casing. The described invention is characterized in that the detection member is a detection bolt.

本発明は上述の如く、請求項１記載の発明にあっては、ケーシング内に被処理物を投入部から投入すると、ケーシング内の一対のスクリュウ軸の咬合回転により被処理物は移送空間で混練圧縮移送され、ダイスプレートの複数個の排出口部から排出され、移送空間での混練圧縮移送及びダイスプレートによる摩擦抵抗により被処理物は減容されつつ加熱され、この加熱により被処理物内に含まれている樹脂分等が溶融し、樹脂分等がバインダーとなり、被処理物は排出口部から固化成型されて排出されることになり、この際、上記ケーシングの内周面に上記一対のスクリュウ軸の羽根部とにより移送空間を形成するバレルライナーを交換自在に設けているから、一対のスクリュウ軸の咬合回転により移送空間で混練圧縮移送され、このとき、被処理物はバレルライナーの内周面に圧摺接され、排出口部に送出されることになり、この被処理物の圧摺接や送出によりバレルライナーの内周面が過度に摩耗損傷したとき、バレルライナーを新たなバレルライナーに交換することができ、このため、新たなケーシングに取り替えたり、ケーシングの内周面を肉盛補修したりすることがなくなり、それだけ、被処理物の処理能率を向上することができると共に、バレルライナーはケーシングに比べて製作コストが低いため、経済性を向上することができる。   As described above, according to the first aspect of the present invention, when an object to be processed is introduced into the casing from the input portion, the object to be processed is kneaded in the transfer space by the occlusal rotation of the pair of screw shafts in the casing. It is compressed and transferred, discharged from a plurality of outlets of the die plate, and heated while being reduced in volume by kneading compression transfer in the transfer space and frictional resistance by the die plate, The contained resin content is melted, the resin content becomes a binder, and the object to be processed is solidified and discharged from the discharge port. At this time, the pair of casings are disposed on the inner peripheral surface of the casing. Since the barrel liner that forms the transfer space with the blade portion of the screw shaft is provided interchangeably, it is kneaded and compressed and transferred in the transfer space by the occlusal rotation of the pair of screw shafts. The processed material is pressed against the inner peripheral surface of the barrel liner and delivered to the discharge port. When the inner peripheral surface of the barrel liner is excessively worn and damaged due to the pressed contact and delivery of the processed material The barrel liner can be replaced with a new barrel liner, which eliminates the need to replace the casing with a new casing or repair the inner peripheral surface of the casing, thereby increasing the processing efficiency of the workpiece. In addition, the barrel liner can be manufactured at a lower cost than the casing, so that the economy can be improved.

又、請求項２記載の発明にあっては、上記ケーシングにその先端部が上記バレルライナーの内周面に露呈する検出部材を着脱自在に設けてなるから、検出部材をケーシングから取り外し、検出部材の先端部の損耗量を例えば検出部材の長さ測定により認識することによりバレルライナーの内面の損耗度を確認することができ、この損耗度の確認によりバレルライナーの交換時期を外部から確認することができ、又、請求項３記載の発明にあっては、上記検出部材は検出ボルトであるから、検出ボルトをバレルライナーにケーシングを介して締付回動することにより取り付けることができると共に検出ボルトを弛緩回動することにより取り外すことができ、損耗度の確認を容易に行うことができる。   Further, in the invention according to claim 2, since the detection member whose tip is exposed to the inner peripheral surface of the barrel liner is detachably provided on the casing, the detection member is removed from the casing, and the detection member is removed. The amount of wear on the inner surface of the barrel liner can be confirmed by recognizing the amount of wear at the tip of the barrel by, for example, measuring the length of the detection member, and the barrel liner replacement time can be confirmed from the outside by checking the degree of wear. In the invention according to claim 3, since the detection member is a detection bolt, the detection bolt can be attached to the barrel liner by tightening and rotating through the casing, and the detection bolt. It can be removed by loosely turning and can easily check the degree of wear.

又、この場合、上記ダイスプレート１１に上記ダイスライナー１６を介してダイスプレート１１から突出する上記一対のスクリュウ軸５・６の突出部５ｃ・６ｃを軸受する軸受部１８を設けてなり、この場合、ダイスプレート１１に平軸受１８ａからなる軸受部１８を設けると共にスクリュウ軸５・６の突出部５ｃ・６ｃを覆うカバー部材１９を設けている。   In this case, the die plate 11 is provided with a bearing portion 18 for bearing the protruding portions 5c and 6c of the pair of screw shafts 5 and 6 protruding from the die plate 11 via the die liner 16. In this case, The die plate 11 is provided with a bearing portion 18 composed of a flat bearing 18a and a cover member 19 that covers the protruding portions 5c and 6c of the screw shafts 5 and 6.

この実施の形態例は上記構成であるから、ケーシング１内に被処理物Ｗを投入部３から投入すると、ケーシング１内の一対のスクリュウ軸５・６の咬合回転により被処理物Ｗは移送空間Ｔで混練圧縮移送され、ダイスプレート１１の複数個の排出口部１２から排出され、移送空間Ｔでの混練圧縮移送及びダイスプレート１１による摩擦抵抗により被処理物Ｗは減容されつつ加熱され、この加熱により被処理物Ｗ内に含まれている樹脂分等が溶融し、樹脂分等がバインダーとなり、被処理物Ｗは排出口部１２の排出ノズル１７から固化成型されて排出されることになる。   Since this embodiment has the above-described configuration, when the workpiece W is thrown into the casing 1 from the throwing portion 3, the workpiece W is transferred into the transfer space by the occlusal rotation of the pair of screw shafts 5 and 6 in the casing 1. The workpiece W is kneaded and compressed and transferred from the plurality of discharge ports 12 of the die plate 11, and the workpiece W is heated while being reduced in volume by the kneading and compression transfer in the transfer space T and the frictional resistance by the die plate 11. By this heating, the resin component contained in the workpiece W is melted, the resin component becomes a binder, and the workpiece W is solidified from the discharge nozzle 17 of the discharge port portion 12 and discharged. Become.

この際、図７、図８の如く、上記ケーシング１の内周面に上記一対のスクリュウ軸５・６の羽根部とにより移送空間Ｔを形成するバレルライナー１３を交換自在に設けているから、一対のスクリュウ軸５・６の咬合回転により移送空間Ｔで混練圧縮移送され、このとき、被処理物Ｗはバレルライナー１３の内周面に圧摺接され、排出口部１２の排出ノズル１４に送出されることになり、この被処理物Ｗの圧摺接や送出によりバレルライナー１３の内周面が過度に摩耗損傷したとき、バレルライナー１３を新たなバレルライナー１３に交換することができ、このため、新たなケーシング１に取り替えたり、ケーシング１の内周面を肉盛補修したりすることがなくなり、それだけ、被処理物Ｗの処理能率を向上することができると共に、バレルライナー１３はケーシング１に比べて製作コストが低いため、経済性を向上することができる。   At this time, as shown in FIGS. 7 and 8, the barrel liner 13 that forms the transfer space T by the blade portions of the pair of screw shafts 5 and 6 is provided on the inner peripheral surface of the casing 1 in a replaceable manner.

The barrel liner 13 can be replaced with a new barrel liner 13 when the inner peripheral surface of the barrel liner 13 is excessively worn and damaged by the pressure-contacting and sending of the workpiece W. For this reason, it is no longer necessary to replace the casing 1 with a new casing 1 or to repair the inner peripheral surface of the casing 1, and accordingly, the processing efficiency of the workpiece W can be improved, and barrel barrels can be improved. Trainer 13 has a low manufacturing cost as compared with the casing 1, it is possible to improve the economy.

The amount of wear on the inner surface of the barrel liner 13 can be confirmed by recognizing the amount of wear at the tip of the detection member 14 by measuring the length of the detection member 14, for example. In this case, since the detection member 14 is the detection bolt 15, the detection bolt 15 can be attached to the barrel liner 13 by being tightened and rotated via the casing 1. At the same time, the detection bolt 15 can be removed by loosely rotating, and the degree of wear can be easily confirmed.

The solidification molding of W can be performed satisfactorily. In this case, the protrusions 5c and 6c of the pair of screw shafts 5 and 6 protruding from the die plate 11 through the die liner 16 are provided on the die plate 11. Since the bearing portion 18 for bearing is provided, the screw shafts 5 and 6 can be supported by the bearing on the drive mechanism 7 side and the bearing portion 18 in a state of being supported by both ends. Damage to the portions 5a and 6a and the casing 1 can be suppressed and power consumption can be reduced.

尚、本発明は上記実施の形態例に限られるものではなく、ケーシング１、スクリュウ軸５・６の形状や大きさ、駆動機構７の構造、バレルライナー１３の材質や大きさ、排出口部１２、検出部材１４、排出ノズル１７、軸受部１８の構造等は適宜変更して設計されものである。   The present invention is not limited to the above embodiment, but the shape and size of the casing 1 and screw shafts 5 and 6, the structure of the drive mechanism 7, the material and size of the barrel liner 13, and the discharge port 12 The structures of the detection member 14, the discharge nozzle 17, and the bearing portion 18 are designed with appropriate changes.
