Description
本発明は、スクリュー式混練機に関し、詳しくは、冷却構造を有するスクリュー式混練機に関する。
The present invention relates to a screw kneader, and more particularly to a screw kneader having a cooling structure.
スクリュー式混練機は、混練対象物が供給された後、スクリューの回転により生じる剪断熱やヒーター熱によって混練対象物・混練物が加熱される構造になっている。ヒーター熱は、スクリューを囲むバレルを介して混練物に与えられるようになっている。一方、冷却に関しては、バレルの内部やスクリューの内部に水などを流すための流路が形成され、この流路を介してバレルやスクリューが冷却され、さらに混練物が冷却される構造になっている。
The screw-type kneader has a structure in which, after a kneading object is supplied, the kneading object / kneaded material is heated by shear heat or heater heat generated by the rotation of the screw. Heater heat is applied to the kneaded material through a barrel surrounding the screw. On the other hand, with regard to cooling, a flow path for flowing water or the like is formed inside the barrel or inside the screw, and the barrel or screw is cooled through this flow path, and the kneaded material is further cooled. Yes.
スクリュー式混練機は、上記のような冷却構造を備えることによって、混練物の温度上昇を抑えることに配慮することができるようになっている。このような冷却構造を備えるスクリュー式混練機は、例えば、特開２００３－２４５５３４号公報や特開２００４－６６７０５号公報に開示されている。
The screw-type kneader is provided with the cooling structure as described above, so that consideration can be given to suppressing the temperature rise of the kneaded product. A screw type kneader having such a cooling structure is disclosed in, for example, Japanese Patent Application Laid-Open Nos. 2003-245534 and 2004-66705.
従来のスクリュー式混練機にあっては、スクリューやバレルによる熱交換制御によって混練物の温度を制御するようになっている。しかしながら、スクリューの回転により生じる剪断熱が高い場合、冷却構造による混練物の冷却が追いつかない場合があるという問題点を有している。また、従来のスクリュー式混練機にあっては、スクリュー先端部や、スクリューの混練機能を持たせた部分に、しばしば過剰な発熱が起こってしまうという問題点を有している。これら問題点に挙げた現象は、樹脂の劣化を引き起こすだけにとどまらず、混練性の悪化を引き起こすことにもつながっている。
In conventional screw kneaders, the temperature of the kneaded product is controlled by heat exchange control using a screw or barrel. However, when the shear heat generated by the rotation of the screw is high, there is a problem that the cooling of the kneaded material by the cooling structure may not catch up. In addition, the conventional screw type kneader has a problem that excessive heat generation often occurs at the screw tip portion or the portion having the screw kneading function. The phenomena listed as these problems not only cause deterioration of the resin but also lead to deterioration of kneadability.
尚、上記問題点の対策として、スクリューの長さ（Ｌ／Ｄ）を延長する、スクリューのエレメント部材の形状・仕様を変更する、などの案が挙げられるが、いずれにしても混練機の大型化につながり、効率的であるとは言えない。
As countermeasures for the above problems, there are proposals such as extending the screw length (L / D) and changing the shape and specifications of the element elements of the screw. It is not efficient.

The nozzle 22, the suction mechanism section 23 that sucks (exhausts) gas after the volatile refrigerant 20 is vaporized, and the operation of the nozzle 22 and the suction mechanism section 23 (for example, the motor or the like operates) are controlled. And a control unit 24. The nozzle 22 is provided in the cooling opening 10 so that the volatile refrigerant 20 in the form of bubbles or mist can be directly sprayed onto the kneaded product.
混練物の温度が所定の温度（閾値）以上であると制御部２４が判断し、泡もしくは霧状となった揮発性を有する冷媒２０が混練物に直接吹き付けられると、この時の気化に伴って混練物の熱が奪われ、混練物が効率よく冷却されるようになっている。直接、混練物を冷却することにより、高い冷却効果を発揮することができるようになっている（従来例ではバレル３の内面に接する部分のみで吸熱が行われる。本発明では気化熱＋温度平衡となり、より均一により効率よく冷却をすることができる）。吸引機構部２３は、吸気用開口部１１に設けられている。
When the control unit 24 determines that the temperature of the kneaded material is equal to or higher than a predetermined temperature (threshold), and the volatile refrigerant 20 in the form of bubbles or mist is sprayed directly onto the kneaded material, the vaporization at this time is accompanied by vaporization. As a result, the heat of the kneaded product is removed, and the kneaded product is efficiently cooled. By directly cooling the kneaded product, a high cooling effect can be exhibited (in the conventional example, heat is absorbed only at the portion in contact with the inner surface of the barrel 3. In the present invention, heat of vaporization + temperature equilibrium is achieved. And more uniform and efficient cooling). The suction mechanism 23 is provided in the intake opening 11.
揮発性を有する冷媒２０は、多量の不純物を含まない冷媒が好ましいものとする。具体的には、水が一例として挙げられる。そして、この水を泡もしくは霧状に噴霧して使用することが好適である。尚、泡もしくは霧状とする理由は、水を大きな水滴の状態で使用すると、冷えすぎてしまうという恐れを有するからである。また、水を大きな水滴の状態で使用すると、スクリュー４が金属製であることから、急激に冷えることによって寸法がずれ、干渉が生じる（クラック発生）という恐れを有するからである。
The volatile refrigerant 20 is preferably a refrigerant that does not contain a large amount of impurities. Specifically, water is an example. And it is suitable to spray and use this water in foam or mist form. The reason for the foam or mist is that if the water is used in the form of large water droplets, there is a risk that it will be too cold. In addition, when water is used in the form of large water droplets, the screw 4 is made of metal, so that there is a risk that the dimensions will shift and interference may occur (crack generation) due to rapid cooling.
以上、本発明のスクリュー式混練機１によれば、揮発性を有する冷媒２０を混練物に直接吹き付けることから、効率的な冷却をすることができるという効果を奏する。
As described above, according to the screw-type kneader 1 of the present invention, since the volatile refrigerant 20 is directly blown onto the kneaded product, there is an effect that efficient cooling can be performed.
この他、本発明は本発明の主旨を変えない範囲で種々変更実施可能なことは勿論である。
Of course, the present invention can be variously modified without departing from the spirit of the present invention.
例えば、バレル３の内部やスクリュー４の内部に水などを流すための流路を形成し、この流路を介してバレル３やスクリュー４を冷却する従来の冷却構造を、本発明に係る冷却構造に付加したり、逆に本発明に係る冷却構造を従来の冷却構造の補助的な冷却構造として使用したりすることも可能であるものとする。
For example, a conventional cooling structure in which a flow path for flowing water or the like is formed in the barrel 3 or the screw 4 and the barrel 3 or the screw 4 is cooled through the flow path is replaced with the cooling structure according to the present invention. In addition, the cooling structure according to the present invention can be used as an auxiliary cooling structure of the conventional cooling structure.
