FIG. 1 is a perspective view showing a schematic configuration of a stirring device according to an embodiment. FIG. 2 is a side view of the stirring device of FIG. FIG. 3 is a plan view of the stirring device of FIG.

撹拌装置１は、撹拌槽１０と、回転軸２０と、撹拌翼３０と、蛇管４０と、を備え、撹拌槽１０の内部にて少なくとも２種以上の撹拌対象の原料（以下「被撹拌物」という。）を撹拌する装置である。被撹拌物としては、例えばニッケルと硫黄とを含む粉状物質を硫黄の融点以上に加熱することにより生成される固液スラリーが挙げられる。 The stirring device 1 includes a stirring tank 10, a rotating shaft 20, a stirring blade 30, and a flexible pipe 40, and at least two or more kinds of raw materials to be stirred (hereinafter referred to as “object to be stirred”) inside the stirring tank 10. It is a device for stirring. Examples of the object to be stirred include a solid-liquid slurry produced by heating a powdery substance containing nickel and sulfur to a temperature equal to or higher than the melting point of sulfur.

撹拌槽１０は、被撹拌物を収容する容器であり、角型の形状を有する。撹拌槽１０が角型の形状を有することにより、複数個の撹拌槽１０を隣接して配置する場合、円筒型の容器である場合と比較して単位面積当たりの容積効率を約２０％高めることができる。撹拌槽１０の上部は開口しており、撹拌槽１０の上部から被撹拌物が投入される。撹拌槽１０の底部１０ｂは、撹拌槽１０内の被撹拌物を排出する排出口（図示せず）へ下降する傾斜を有する傾斜面を形成することが好ましい。これにより、撹拌槽１０内の被撹拌物をスムーズに排出できる。ただし、撹拌槽１０の底部１０ｂは傾斜面を形成することなく、例えば図４に示されるように、平坦面を形成していてもよい。なお、図４は、一実施形態の撹拌装置の変形例を説明するための図である。 The stirring tank 10 is a container that stores an object to be stirred and has a rectangular shape. Since the agitation tank 10 has a rectangular shape, when a plurality of agitation tanks 10 are arranged adjacent to each other, the volumetric efficiency per unit area can be increased by about 20% as compared with the case of a cylindrical container. You can The upper part of the stirring tank 10 is open, and the object to be stirred is introduced from the upper part of the stirring tank 10. It is preferable that the bottom portion 10b of the agitation tank 10 has an inclined surface having an inclination that descends to a discharge port (not shown) for discharging an object to be stirred in the agitation tank 10. Thereby, the object to be stirred in the stirring tank 10 can be smoothly discharged. However, the bottom portion 10b of the stirring tank 10 may form a flat surface as shown in FIG. 4, for example, without forming an inclined surface. Note that FIG. 4 is a diagram for explaining a modified example of the stirring device according to the embodiment.

回転軸２０は、撹拌槽１０内で鉛直方向に伸びて設けられている。回転軸２０の上端には、回転軸２０を回転駆動する駆動手段（図示せず）が設けられ、駆動手段の駆動力により回転軸２０が回転する。駆動手段は、例えば減速機付モータであってよい。なお、駆動手段は、回転軸２０の下端に設けられていてもよい。 The rotating shaft 20 is provided in the stirring tank 10 so as to extend in the vertical direction. A drive unit (not shown) that rotationally drives the rotary shaft 20 is provided at the upper end of the rotary shaft 20, and the rotary shaft 20 is rotated by the driving force of the drive unit. The driving means may be, for example, a motor with a reducer. The driving means may be provided at the lower end of the rotary shaft 20.

撹拌翼３０は、回転軸２０に取り付けられている。撹拌翼３０は、回転軸２０を回転中心として回転することで、回転軸２０と平行な方向の流れ、例えば被撹拌物を下向きに吐出する流れを形成する。撹拌翼３０の種類は、特に限定されないが、例えば被撹拌物の粘度、撹拌槽１０の大きさ等に応じて選択される。撹拌翼３０の種類としては、例えばプロペラ、ピッチドパドル形、傾斜タービン形等が挙げられる。撹拌翼３０の数は、特に限定されないが、被撹拌物の粘度、撹拌槽１０の大きさ等に応じて選択される。撹拌翼３０の数は、１つであってもよく、２つ以上であってもよい。一実施形態では、回転軸２０に３つの撹拌翼３０ａ，３０ｂ，３０ｃが上下方向に間隔を空けて取り付けられている。なお、図１から図３では、撹拌翼３０ａ，３０ｂ，３０ｃの具体的な形状の図示を省略し、いずれも円柱形状で示している。 The stirring blade 30 is attached to the rotating shaft 20. The stirring blade 30 rotates about the rotating shaft 20 to form a flow in a direction parallel to the rotating shaft 20, for example, a flow for discharging the agitated object downward. The type of the stirring blade 30 is not particularly limited, but is selected according to, for example, the viscosity of the object to be stirred, the size of the stirring tank 10, and the like. Examples of the type of the stirring blade 30 include a propeller, a pitched paddle type, and an inclined turbine type. The number of stirring blades 30 is not particularly limited, but is selected according to the viscosity of the object to be stirred, the size of the stirring tank 10, and the like. The number of stirring blades 30 may be one or may be two or more. In one embodiment, three stirring blades 30a, 30b, 30c are attached to the rotary shaft 20 at intervals in the vertical direction. It should be noted that in FIGS. 1 to 3, the concrete shapes of the stirring blades 30a, 30b, 30c are omitted, and all are shown as columnar shapes.

蛇管４０は、撹拌槽１０の側壁１０ｓと撹拌翼３０との間に設けられ、撹拌槽１０内の温度を調整する温度調整手段である。蛇管４０は、回転軸２０と同じ軸方向の螺旋軸を有する螺旋状に形成され、内部に熱媒体を通流する配管である。ここで、螺旋とは、回転しながら回転面（図１〜３におけるＸＹ平面）に垂直成分のある方向（図１〜３におけるＺ方向）へ上昇する曲線を意味し、回転面における形状は特に限定されない。回転面における形状は、例えば円形、楕円形、矩形等であってもよく、また例えば図３に示されるように、直線と曲線とを組み合わせた形状であってもよい。熱媒体は、例えば蒸気等の熱媒、水等の冷媒であってよい。蛇管４０の内部に熱媒を流すことにより、撹拌槽１０の内部を加熱して被撹拌物を加熱できる。また、蛇管４０の内部に冷媒を流すことにより、撹拌槽１０の内部を冷却して被撹拌物を冷却できる。例えば、撹拌槽１０の内部にてニッケルと硫黄とを含む粉状物質を投入して撹拌する場合、蛇管４０の内部に熱媒を流すことで撹拌槽１０の内部を硫黄の融点以上、ニッケルの融点未満の温度に加熱する。一実施形態では、撹拌槽１０の４つの角部のそれぞれに側壁１０ｓから所定の間隔を有して蛇管４０ａ，４０ｂ，４０ｃ，４０ｄが設けられている。ただし、蛇管４０の配置及び数は図示の例に限定されるものではない。また、図示の例では、蛇管４０は支持部材４１により撹拌槽１０に固定されているが、上方から吊るされていてもよい。 The flexible pipe 40 is provided between the side wall 10 s of the stirring tank 10 and the stirring blade 30 and is a temperature adjusting means for adjusting the temperature inside the stirring tank 10. The flexible pipe 40 is a pipe that is formed in a spiral shape having a spiral axis in the same axial direction as the rotating shaft 20 and allows a heat medium to flow inside. Here, the spiral means a curve that rises in a direction (Z direction in FIGS. 1 to 3) having a component perpendicular to the rotation surface (XY plane in FIGS. 1 to 3) while rotating, and the shape on the rotation surface is particularly Not limited. The shape of the plane of rotation may be, for example, a circle, an ellipse, a rectangle, or the like, or may be a combination of straight lines and curved lines, as shown in FIG. The heat medium may be, for example, a heat medium such as steam or a refrigerant such as water. By flowing the heating medium inside the flexible tube 40, the inside of the stirring tank 10 can be heated to heat the object to be stirred. Further, by flowing the refrigerant inside the flexible tube 40, the inside of the stirring tank 10 can be cooled and the object to be stirred can be cooled. For example, when a powdery substance containing nickel and sulfur is charged and stirred in the stirring tank 10, a heating medium is caused to flow inside the spiral tube 40 so that the inside of the stirring tank 10 has a melting point of sulfur or higher, Heat to a temperature below the melting point. In one embodiment, each of the four corners of the stirring tank 10 is provided with a flexible tube 40a, 40b, 40c, 40d at a predetermined distance from the side wall 10s. However, the arrangement and the number of the flexible tubes 40 are not limited to the illustrated example. Further, in the illustrated example, the flexible pipe 40 is fixed to the stirring tank 10 by the support member 41, but may be suspended from above.

蛇管４０の外側部４０１は、撹拌槽１０の側壁１０ｓに沿って配置されている。蛇管４０の外側部４０１と撹拌槽１０の側壁１０ｓとの間の水平距離Ｌは９０ｍｍ以下である。これにより、撹拌翼３０から下向きに吐出された被撹拌物が撹拌槽１０の底部１０ｂに沿って広がり、底部１０ｂと蛇管４０の下の隙間を通った後に側壁１０ｓに沿って形成される流速の大きい上昇流の近傍に蛇管４０が位置する。そのため、流速が大きい被撹拌物を蛇管４０に接触させることができるので、伝熱速度が大きくなる。その結果、撹拌槽１０内の被撹拌物を効率よく加熱又は冷却できる。なお、蛇管４０の外側部４０１と撹拌槽１０の側壁１０ｓとの間の水平距離Ｌとは、外側部４０１の外端と側壁１０ｓとの間の水平距離を意味する。 The outer part 401 of the flexible tube 40 is arranged along the side wall 10 s of the stirring tank 10. The horizontal distance L between the outer side portion 401 of the flexible tube 40 and the side wall 10s of the stirring tank 10 is 90 mm or less. As a result, the object to be stirred discharged downward from the stirring blade 30 spreads along the bottom portion 10b of the stirring tank 10, passes through the gap between the bottom portion 10b and the flexible pipe 40, and then is formed along the side wall 10s. The flexible pipe 40 is located in the vicinity of a large upflow. Therefore, the object to be stirred having a high flow rate can be brought into contact with the flexible tube 40, and the heat transfer rate is increased. As a result, the object to be stirred in the stirring tank 10 can be efficiently heated or cooled. The horizontal distance L between the outer side portion 401 of the flexible tube 40 and the side wall 10s of the stirring tank 10 means the horizontal distance between the outer end of the outer side portion 401 and the side wall 10s.

また、蛇管４０の外側部４０１と撹拌槽１０の側壁１０ｓとの間の水平距離Ｌは５０ｍｍ以上であることが好ましい。これにより、撹拌槽１０に収容された被撹拌物を排出して蛇管４０の表面をブラシ等により清掃する等のメンテナンス時の作業が容易に行える。また、蛇管４０が撹拌槽１０の上方から吊るされている場合、撹拌槽１０内の被撹拌物の流れによって蛇管４０が揺れて撹拌槽１０の側壁１０ｓに衝突して撹拌槽１０の寿命が短くなる場合があるが、水平距離Ｌを５０ｍｍ以上確保していれば衝突を抑制できる。 Further, the horizontal distance L between the outer side portion 401 of the flexible tube 40 and the side wall 10s of the stirring tank 10 is preferably 50 mm or more. As a result, the work at the time of maintenance such as discharging the object to be stirred contained in the stirring tank 10 and cleaning the surface of the flexible tube 40 with a brush or the like can be easily performed. Further, when the flexible pipe 40 is suspended from above the stirring tank 10, the flexible pipe 40 is shaken by the flow of the object to be stirred in the stirring tank 10 and collides with the side wall 10 s of the stirring tank 10 to shorten the life of the stirring tank 10. However, if the horizontal distance L is 50 mm or more, the collision can be suppressed.

以上に説明したように、一実施形態の撹拌装置１によれば、蛇管４０の一部である外側部４０１が撹拌槽１０の側壁１０ｓからの水平距離Ｌが９０ｍｍ以下の範囲内に配置されている。これにより、撹拌翼３０から下向きに吐出された被撹拌物が撹拌槽１０の底部１０ｂに沿って広がり、底部１０ｂと蛇管４０の下の隙間を通った後に側壁１０ｓに沿って形成される流速の大きい上昇流の近傍に蛇管４０が位置する。そのため、流速が大きい被撹拌物を蛇管４０に接触させることができるので、伝熱速度が大きくなる。その結果、撹拌槽１０内の被撹拌物を効率よく加熱又は冷却できる。 As described above, according to the stirring device 1 of the embodiment, the outer portion 401 that is a part of the flexible tube 40 is arranged within the range in which the horizontal distance L from the side wall 10s of the stirring tank 10 is 90 mm or less. There is. As a result, the object to be stirred discharged downward from the stirring blade 30 spreads along the bottom portion 10b of the stirring tank 10, passes through the gap between the bottom portion 10b and the flexible pipe 40, and then is formed along the side wall 10s. The flexible pipe 40 is located in the vicinity of a large upflow. Therefore, the object to be stirred having a high flow rate can be brought into contact with the flexible tube 40, so that the heat transfer rate is increased. As a result, the object to be stirred in the stirring tank 10 can be efficiently heated or cooled.

（評価）
ＡＮＳＹＳ社の汎用熱流体解析ソフトウェア（ＣＦＸ）を用いた気液二相流（自由界面）解析により、条件１〜４の撹拌装置を用いた場合の蛇管４０に接する融液の量を評価した。 (Evaluation)
By a gas-liquid two-phase flow (free interface) analysis using general-purpose thermo-fluid analysis software (CFX) from ANSYS, the amount of the melt in contact with the flexible pipe 40 when the stirring device under the conditions 1 to 4 was used was evaluated.

評価の際、気相として空気、液相として溶融硫黄の物性値（工場の操業条件）を適用し、乱流モデルとしてＳＳＴ（Shear Stress Transport）モデルを用いた。また、蛇管４０に接する融液の量を評価するため、蛇管４０から５ｍｍ離れた面上で融液の速度を積分し、その積分値を蛇管４０に接する融液の量とみなして評価した。 At the time of evaluation, air was used as the gas phase, the physical properties of molten sulfur (the operating conditions of the factory) were applied as the liquid phase, and the SST (Shear Stress Transport) model was used as the turbulence model. Further, in order to evaluate the amount of the melt in contact with the flexible tube 40, the velocity of the melt was integrated on a surface 5 mm away from the flexible tube 40, and the integrated value was regarded as the amount of the melt in contact with the flexible tube 40 for evaluation.

ＣＦＸを用いた評価の結果、蛇管４０に接する融液の量は、条件１では３２．６ｍ３／秒、条件２では３６．２ｍ３／秒、条件３では３８．７３ｍ３／秒、条件４では４２．１ｍ３／秒であった。これらの結果から、蛇管４０の外側部４０１と撹拌槽１０の側壁１０ｓとの水平距離を９０ｍｍ、７０ｍｍ、５０ｍｍとすることにより、蛇管４０に接する融液の量が増加し、撹拌槽１０内の融液を効率よく加熱又は冷却できると考えられる。また、蛇管４０の外側部４０１と撹拌槽１０の側壁１０ｓとの水平距離を短くするほど、蛇管４０に接する融液の量が増加し、撹拌槽１０内の融液をより効率よく加熱又は冷却できると考えられる。 Results of evaluation using CFX, the amount of the melt in contact with the flexible tube 40, the condition 1 32.6m 3 / sec, the condition 2 36.2m 3 / sec, condition 3, 38.73M 3 / sec, condition 4 Was 42.1 m 3 /sec. From these results, by setting the horizontal distance between the outer side portion 401 of the flexible tube 40 and the side wall 10s of the stirring tank 10 to 90 mm, 70 mm, and 50 mm, the amount of the melt in contact with the flexible tube 40 increases and the inside of the stirring tank 10 increases. It is considered that the melt can be efficiently heated or cooled. Further, as the horizontal distance between the outer side portion 401 of the flexible tube 40 and the side wall 10s of the stirring tank 10 is shortened, the amount of the melt in contact with the flexible tube 40 increases, and the melt in the stirring tank 10 is heated or cooled more efficiently. It is thought to be possible.

今回開示された実施形態はすべての点で例示であって制限的なものではないと考えられるべきである。上記の実施形態は、添付の請求の範囲及びその趣旨を逸脱することなく、様々な形態で省略、置換、変更されてもよい。 The embodiments disclosed this time are to be considered as illustrative in all points and not restrictive.
