Description

本発明は、混練装置に関し、特に、良好な混練が行える混練装置に関するものである。   The present invention relates to a kneading apparatus, and more particularly to a kneading apparatus capable of performing good kneading.

中、高粘度から超高粘度材料の混練、捏和処理は、混練槽内に混練材料を入れ、混練槽内に並列に設置され、強力に反対方向に回転するブレ−ド（ロータ）を備えた混練装置（例えば特許文献１など）で行われる。   For kneading and kneading of medium to high viscosity materials, the kneading material is placed in a kneading tank and installed in parallel in the kneading tank and equipped with a blade (rotor) that rotates strongly in the opposite direction. The kneading apparatus (for example, Patent Document 1) is used.

特開２００６−３０５５１４号公報JP 2006-305514 A

従来の混練装置では、混練後の希釈工程において均一な希釈分散ができるよう混練槽底部中央の棟状部の壁面とロータ翼とのクリアランスを比較的広くとらなくてはならず、高いせん断力を掛けることが困難であったり、混練槽底部中央の棟状の凸部に混練材料の一部が蓄積し易く、均一な混練が行えなかったり、蓄積した混練材料を除去する作業が必要なため、混練作業の効率が低下するなどの問題点があった。   In a conventional kneading apparatus, the clearance between the wall of the ridge-shaped part at the center of the bottom of the kneading tank and the rotor blades must be relatively wide so that uniform dilution and dispersion can be achieved in the dilution process after kneading, and a high shearing force is required. Because it is difficult to hang, part of the kneaded material tends to accumulate on the ridge-shaped convex part at the center of the bottom of the kneading tank, uniform kneading cannot be performed, or work to remove the accumulated kneaded material is necessary, There was a problem that the efficiency of the kneading work was lowered.

本発明では、均一な混練が行え、効率よく混練作業が行える混練装置を提供することを目的とする。   An object of the present invention is to provide a kneading apparatus that can perform uniform kneading and perform kneading work efficiently.

本発明者らは、混練装置について鋭意検討した結果、混練装置を下記の構成にすれば、均一な混練が行え、効率よく混練作業が行える混練装置を提供できることを見出し、本発明をなすに至った。   As a result of intensive studies on the kneading apparatus, the present inventors have found that if the kneading apparatus has the following configuration, it is possible to provide a kneading apparatus that can perform uniform kneading and perform kneading work efficiently, and has led to the present invention. It was.

すなわち、混練材料を収容する混練槽と、該混練槽に収容された混練材料を混練する並列した２本のロータを備える混練装置において、前記混練槽底部中央の棟状の凸部が交換可能に構成されていることを特徴とする。   That is, in a kneading apparatus including a kneading tank for storing a kneading material and two rotors arranged in parallel for kneading the kneading material stored in the kneading tank, the ridge-shaped convex portion at the center of the bottom of the kneading tank can be replaced. It is configured.

前記棟状の凸部を構成する主材料の線膨張係数が、７×１０−５（１／℃）以上であることを特徴とする。
The linear expansion coefficient of the main material constituting the ridge-shaped convex portion is 7 × 10 −5 (1 / ° C.) or more.

混練材料を収容する混練槽と、該混練槽に収容された混練材料を混練する並列した２本のロータを備える混練装置において、前記混練槽底部中央の棟状の凸部が交換可能に構成されているために、この部分における、ロータ翼と槽内面とのクリアランスを、混練材量の種類、混練目的に応じて、変えることができるので、幅広い材料の混練に対応することができる。また、棟状の凸部を構成する主材料の線膨張係数が好ましい範囲に設定されているので、混練時に槽内の温度が上昇すると、棟状の凸部が上下左右に膨張し、この部分におけるロータ翼と槽内面とのクリアランスが小さくなるので、凸部に混練物が蓄積しにくくなり、また、混練におけるせん断力も大きくなる。   In a kneading apparatus comprising a kneading tank for storing a kneading material and two parallel rotors for kneading the kneading material stored in the kneading tank, the ridge-shaped convex part at the center of the bottom of the kneading tank is configured to be replaceable. For this reason, the clearance between the rotor blade and the tank inner surface in this portion can be changed according to the type of kneading material and the purpose of kneading, so that a wide range of materials can be kneaded. In addition, since the linear expansion coefficient of the main material constituting the ridge-shaped convex portion is set within a preferable range, when the temperature in the tank rises during kneading, the ridge-shaped convex portion expands vertically and horizontally, and this part Since the clearance between the rotor blade and the inner surface of the tank becomes small, the kneaded material is difficult to accumulate on the convex portion, and the shearing force in kneading increases.

更に、本発明の混練装置により分散性の良い磁性塗料を得る事が出来、表面性・充填性が良い磁気テープを得る事が出来る。   Furthermore, a magnetic coating material having good dispersibility can be obtained by the kneading apparatus of the present invention, and a magnetic tape having good surface properties and filling properties can be obtained.

以下、図面を参照して、本発明の混練装置について説明する。図１に従来の代表的な一例の混練装置の断面構造図を示す。従来の混練装置１ａは、混練材料を収容する混練槽１０の内部に、混練槽に収容された混練材料を混練する並列した２本のロータ２を備えている。ロータ２は、ロータ軸２ａとロータ翼２ｂとから構成されている。ロータ２が回転するとロータ翼２ｂの最外部は図面の１点破線のように円筒面を描くが、この円筒面と混練槽１０の内面は所定のクリアランスｄ１を保つように設計されている。また、二つのロータの円筒面は外周面が重ならず、所定のクリアランスｄ２を保つように設計されている。クリアランスｄ２は、大きいほうが混練後の希釈分散が均一に行い易いが、凸部１００の上部に混練物が蓄積し易くなる。   Hereinafter, the kneading apparatus of the present invention will be described with reference to the drawings. FIG. 1 shows a cross-sectional structure diagram of a conventional representative example of a kneading apparatus. A conventional kneading apparatus 1a includes two parallel rotors 2 for kneading the kneaded material stored in the kneading tank inside the kneading tank 10 for storing the kneaded material. The rotor 2 includes a rotor shaft 2a and rotor blades 2b. When the rotor 2 rotates, the outermost portion of the rotor blade 2b draws a cylindrical surface as indicated by a one-dot broken line in the drawing, and the cylindrical surface and the inner surface of the kneading tank 10 are designed to maintain a predetermined clearance d1. Further, the cylindrical surfaces of the two rotors are designed so that the outer peripheral surfaces do not overlap and a predetermined clearance d2 is maintained. The larger the clearance d2, the easier the dilution and dispersion after kneading is performed, but the kneaded material tends to accumulate on the top of the convex portion 100.

一般的に、クリアランスｄ１は、大きいと混練材料の混合効率が良くなるが、材料に大きなせん断力は掛けられなくなり、小さいと材料に大きなせん弾力が掛けられるために、材料を分散する力は大きくなるが、混合効率が低下するという傾向があるため、使用する混練材量の種類、混練目的に応じて、適宜設計されている。 Generally, when the clearance d1 is large, the mixing efficiency of the kneaded material is improved. However, a large shearing force is not applied to the material, and when the clearance d1 is small, a large elastic force is applied to the material. However, since there is a tendency that the mixing efficiency is lowered, the mixing efficiency is appropriately designed according to the kind of the kneading material to be used and the kneading purpose.

混練装置１ａは、このような構成になっているために、図１に示したように矢印の方向にロータが回転すると、図２のＤのように混練槽１０の底部中央の棟状凸部１００の上部に混練物が付着蓄積し易い傾向にある。   Since the kneading apparatus 1a has such a configuration, when the rotor rotates in the direction of the arrow as shown in FIG. 1, a ridge-like convex portion at the center of the bottom of the kneading tank 10 as shown in FIG. The kneaded material tends to adhere and accumulate on the top of 100.

棟状凸部１００にこのように混練材料が付着しても、すぐに外れて他の混練材料と混ざるようであれば、特に問題はないが、混練初期に付着したものが混練工程中そのまま付着し続ける傾向があるため、ここの付着した混練材料は十分に混練されないという問題点が生じる。そこで、通常、混練物が付着すると、必要に応じてロータの回転を止めて、付着物を外す作業を行うので、作業が煩雑になったり、効率が低下する問題が生じる。   Even if the kneaded material adheres to the ridge-shaped convex portion 100 in this way, there is no particular problem as long as it comes off immediately and mixes with other kneaded materials, but the material adhering to the initial stage of kneading is adhered as it is during the kneading process. Therefore, there is a problem that the adhering kneaded material is not sufficiently kneaded. Therefore, normally, when the kneaded material adheres, the rotation of the rotor is stopped as necessary, and the work of removing the adhering material is performed, so that the work becomes complicated and the efficiency decreases.

本発明の混練装置はこのような問題に対応するもので、以下具体的に説明する。図３に本発明の、一例の混練装置の断面構造図を示す。本発明の混練装置１ｂは、ロータ２の構成は、従来のものと同様である。   The kneading apparatus of the present invention addresses such a problem and will be specifically described below. FIG. 3 shows a sectional structural view of an example of the kneading apparatus of the present invention. In the kneading apparatus 1b of the present invention, the configuration of the rotor 2 is the same as the conventional one.

混練槽１０の前面部１０ａは取り外し可能になっており、固定ピン１２０により固定されている。   The front surface portion 10 a of the kneading tank 10 can be removed and is fixed by a fixing pin 120.

混練槽１０の底部の構造が、従来のものと異なり、底部中央の棟状凸部１３０が交換可能に構成されている。   The structure of the bottom of the kneading tank 10 is different from the conventional one, and the ridge-shaped convex part 130 at the center of the bottom is configured to be replaceable.

棟状凸部１３０の底部１３０ａは楔形状に加工されており混合槽１０の底部に内嵌固定できるようになっている。このため、混練材量の種類、混練目的に応じて、この部分におけるロータ翼２２とのクリアランスｄ１を変えることができる。このため、棟状凸部１３０の上部に付着する混練物の付着量を抑制することができる。   The bottom portion 130 a of the ridge-shaped convex portion 130 is processed into a wedge shape and can be fitted and fixed to the bottom portion of the mixing tank 10. For this reason, according to the kind of kneading | mixing material amount and the kneading | mixing objective, the clearance d1 with the rotor blade | wing 22 in this part can be changed. For this reason, the adhesion amount of the kneaded material adhering to the upper part of the ridge-shaped convex part 130 can be suppressed.

また、棟状凸部１３０を構成する材料の線膨張係数の大きなものにすることにより、混練の進行に伴う、混練槽１０内の温度上昇に伴い、熱膨張により棟状凸部１３０を大きくすることが可能となるので、図５に示したように、混練の進行に伴い、ロータ翼２ｂとのクリアランスを小さくすることができる（ｄ１ａ→ｄ１ｂ）。クリアランスが小さくなると、棟状凸部１００の上部に付着する混練物を抑制することができるとともに、混練物により大きなせん断力を掛けることができるため、混練材料を良好に分散することができる。   Further, by making the material constituting the ridge-shaped convex portion 130 have a large linear expansion coefficient, the ridge-shaped convex portion 130 is enlarged due to thermal expansion as the temperature in the kneading tank 10 increases with the progress of kneading. Therefore, as shown in FIG. 5, the clearance with the rotor blade 2b can be reduced as the kneading progresses (d1a → d1b). When the clearance becomes small, the kneaded material adhering to the upper part of the ridge-shaped convex portion 100 can be suppressed, and a large shearing force can be applied to the kneaded material, so that the kneaded material can be dispersed well.

棟状凸部１３０のロータ軸方向の熱膨張に対しては、棟状凸部１３０と混練槽１０の内面との間にパッキン（弾性材料）１１０を設置して対応することができる。   The thermal expansion of the ridge-shaped convex portion 130 in the rotor axial direction can be dealt with by installing a packing (elastic material) 110 between the ridge-shaped convex portion 130 and the inner surface of the kneading tank 10.

また、混練が進行し、希釈工程を行なうときは混練槽１０の温度が下がるのでのクリアランスを大きくすることもできる。これにより、希釈効率がよくなり均一な分散をすることができる。   Further, when the kneading proceeds and the dilution process is performed, the clearance for lowering the temperature of the kneading tank 10 can be increased. Thereby, the dilution efficiency is improved and uniform dispersion can be achieved.

棟状凸部１００を構成する材料の線膨張係数の好ましい範囲は、混練装置のスケール、混練材料の種類、混練の目的等により異なるが、７×１０−５（１／℃）以上であることが好ましい。
The preferable range of the linear expansion coefficient of the material constituting the ridge-shaped convex portion 100 varies depending on the scale of the kneading apparatus, the type of the kneading material, the purpose of kneading, and the like, but is 7 × 10 −5 (1 / ° C.) or more. Is preferred.
