本発明は、撹拌槽内部に冷却・加熱用のコイルを存する
撹拌装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a stirring device having coils for cooling and heating inside a stirring tank.

にコイルを配置するものであった。BACKGROUND ART Liquids with high viscosity have poor stirring efficiency, making it difficult to quickly and uniformly heat or cool the liquid. Therefore, in order to improve cooling or heating efficiency in stirring and mixing devices for highly viscous liquids, attempts have been made to place cooling/heating coils inside the stirring tank, but in this case, the rotation of the stirring blades is The coil was placed outside the stirring blade and close to the inner wall of the stirring tank to avoid interference.

し、コイル付近の液体には流動を生じなくなり、部分的
に攪拌できなくなる欠点があった。Problems to be Solved by the Invention However, in such a device, when cooling water is flowed through the coil, supercooling occurs between the coil and the inner wall surface of the stirring tank if the liquid has a high viscosity, and this portion The disadvantage is that the viscosity of the liquid increases, and the liquid near the coil no longer flows, making stirring partially impossible.

は加熱しながら攪拌混合できる撹拌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 stirring device in which a cooling/heating coil is disposed inside a stirring tank, which can stir and mix a highly viscous liquid while efficiently cooling or heating it.

に回転可能な状態で位置することを特徴とする。Means for Solving the Problems The device of the present invention has a cylindrical stirring tank having a rotating shaft in the center, and a wall (6) on the inner wall of the stirring tank, with the rotating shaft as the center.
Cooling and heating coils are suspended at regular intervals from the stirring blade, and the stirring blade, which is shaped like an anchor, is attached to the rotating shaft, and the stirring blade extends above the stirring blade. The tip is rotatably located between the cooling/heating coil and the inner wall surface of the stirring tank.

し、粘度の高い液体にあっても攪拌効率を著しく増し、
非常に効率の良い冷却または加熱混合を可能とする。That is, in the present invention, in the case of stirring and mixing high viscosity liquids, the cooling/heating coil, which was conventionally considered to impair the stirring efficiency during cooling, is made to be able to rotate the stirring blade between the coil and the inner wall of the stirring tank. This allows it to be used like a baffle plate, significantly increasing stirring efficiency even in highly viscous liquids.
Allows for highly efficient cooling or heating mixing.

ットを取りつけるとよい。A cooling/heating jacket may be attached to the lower outer periphery of the stirring tank as usual. In this case, in order to facilitate the attachment and detachment of the stirring blades to the rotating shaft, the stirring tank is formed so that it can be divided into upper and lower halves. It is preferable to hang a cooling/heating coil on the upper wall of the stirring tank or on the lid of the stirring tank, and to attach a cooling/heating jacket to the lower part of the stirring tank.

棒状部分を含む垂直面からの折曲角度は３５〜５０°程

は５〜２０°程度であるのが好ましい。Note that the stirring blades are formed by vertically and/or horizontally tilting rectangular blades upward at both ends of a rod-shaped portion having means for attaching to a central rotating shaft and extending substantially horizontally. By attaching it, the flow of liquid during stirring is directed upward, and the stirring efficiency of highly viscous liquid can be further improved. It is preferable that the bending angle of the stirring blade from a vertical plane including the rotating shaft and the rod-shaped portion is about 35 to 50 degrees, and the angle of inclination to the vertical plane is about 5 to 20 degrees.
次に、図面に従って本発明の詳細な説明する。Next, the present invention will be explained in detail according to the drawings.

A cooling/heating coil (2) is suspended from the wall of the upper part of the stirring tank (8), and a cooling/heating coil (2) is hung on the outer periphery of the lower part of the stirring tank (9). jacket (7) is attached. In addition, the rotation axis (3) is connected to a motor (not shown) located above.
A stirring blade (4) is attached to the lid (1o) in a state where it can be driven by the rotary shaft (3), and is rotated by the rotating shaft (3).
The tip (5) extending upward is the cooling/heating coil (2).

一な混合及び熱交換が可能となる。The liquid placed in the stirring tank (1) is stirred and mixed by the stirring blade (4) while being doubly cooled or heated by water or heated steam introduced into the jacket (7) and coil (2). However, because the tip (5) of the stirring blade (4) is located between the coil (2) and the inner wall surface (6) of the stirring tank (1), the liquid has a high viscosity of 500 to 50,000 cps. However, it can be stirred very efficiently, and uniform mixing and heat exchange can be achieved in a short period of time.

効率は一定で、動力を減少できる利点がある。In addition, in such a stirring device, if the angle of the stirring blade (4) is changed in the vertical direction and/or the horizontal direction, the stirring efficiency remains constant and there is an advantage that the power can be reduced.

た。その結果を第１表に示す。Colored chips were put into a CMC aqueous solution with a viscosity of 3000 cps at 25°C, and A, B, and C shown in Figures 2 and 3 were added.
Using the device shown in Figure 1, which uses three types of stirring blades (4),
) was stirred at different rotational speeds, and the time until uniform stirring was achieved (the colored chips were uniformly dispersed throughout) was measured. The results are shown in Table 1.

いるものである。The stirring blades A, B, and C all extend substantially horizontally,
Rectangular blades (12), almost similar to the stirring blades (4) in Figure 1, are attached upward at both ends of a rod-shaped portion (11) that has a means for attaching it to the rotating shaft (3) in the center. However, the two wings (12) of A are connected to the rotating shaft (3) and the rod-shaped part (1
The upper end is tilted forward and backward at an angle of 15 degrees with respect to the vertical plane including 1). The two wings (12) of C are attached by twisting their upper ends back and forth at an angle of 15 degrees with respect to the above vertical plane, and at the same time tilting the outer edges left and right at an angle of 45 degrees. This is what is attached to it.
第１表 但し、装置Ｉはコイル（２）を設けてない装置。Table 1 However, device I is not equipped with a coil (2).
装置■はコイル（２）を設けた装置。Device ■ is a device equipped with a coil (2).

装置Ｉ）と同等の攪拌効率が得られることがわかる。From the results in Table 1, it can be seen that in the device (2) in which the coil (2) is provided in a fixed relationship with the stirring blade (4) according to the present invention, the stirring blade (4)
Regardless of the shape of ), if coil (2) does not exist (
It can be seen that stirring efficiency equivalent to that of device I) can be obtained.
更に、装置■ではコイル（２）が邪魔板として働くため
、コイル（２）が存在しない装置■の場合より著しく少
ない動力（電流）で均一な撹拌が可能となっている。Furthermore, since the coil (2) in device (2) acts as a baffle plate, uniform stirring is possible with significantly less power (current) than in device (2), which does not have the coil (2).
なお、撹拌翼（４）がＣの形状をとる場合、極端に少な
