Description

本発明は、混合を目的とした撹拌装置に関する。   The present invention relates to a stirring device for mixing purposes.

従来から、被撹拌物を撹拌する撹拌装置として、円筒形状の撹拌槽と、該撹拌槽の中心部に配置される撹拌軸と、該撹拌軸の下部側に取り付けられる撹拌翼とが設けられたものが知られている。撹拌翼には、撹拌軸の周方向に沿って複数の羽根が設けられている。   Conventionally, as a stirring device for stirring an object to be stirred, a cylindrical stirring tank, a stirring shaft arranged at the center of the stirring tank, and a stirring blade attached to the lower side of the stirring shaft have been provided. Things are known. The stirring blade is provided with a plurality of blades along the circumferential direction of the stirring shaft.

撹拌軸が軸芯を中心に回転すると、撹拌翼が撹拌軸とともに回転する。そして、撹拌翼の複数の羽根は、撹拌槽内を旋回して受けた被撹拌物を後方に流動させ、撹拌翼の回転で発生する回転流により又は羽根自体により被撹拌物をせん断する。   When the stirring shaft rotates around the axis, the stirring blade rotates together with the stirring shaft. The plurality of blades of the stirring blades cause the material to be stirred to swirl in the stirring tank to flow backward, and shear the material to be stirred by the rotating flow generated by the rotation of the stirring blades or by the blades themselves.

このような機能を有する撹拌翼には、被撹拌物をせん断するせん断性能に特化したせん断特化型撹拌翼と、被撹拌物を流動させて被撹拌物を循環させる循環性能に特化した循環特化型撹拌翼とがある。   The stirring blade having such a function is specialized in a shear-specific stirring blade specialized in shearing performance for shearing the stirring object, and in circulation performance for circulating the stirring object by flowing the stirring object. There are circulation-specific stirring blades.

せん断特化型撹拌翼には、例えば、板状の羽根を凹形状にしたコンケーブ翼などのような、羽根が受けた被撹拌物を撹拌軸の径方向に流動させるものが多い。これらの撹拌翼は、羽根近傍で被撹拌物をせん断することにより被撹拌物を細分化することに特化している（例えば、特許文献１参照）。   Many shear-specific stirring blades, such as concave blades with plate-like blades, cause the stirring object received by the blades to flow in the radial direction of the stirring shaft. These stirring blades specialize in subdividing the object to be stirred by shearing the object to be stirred in the vicinity of the blade (for example, see Patent Document 1).

循環特化型撹拌翼には、例えば、軸流翼タイプの撹拌翼などのような、羽根が受けた被撹拌物を下方に流動させるものが多い。これらの撹拌翼は、撹拌槽内で被撹拌物を循環させることに特化している（例えば、特許文献２参照）。   Many of the circulation-specific stirring blades, such as an axial flow blade type stirring blade, cause the object to be stirred received by the blade to flow downward. These stirring blades specialize in circulating an object to be stirred in a stirring tank (see, for example, Patent Document 2).

撹拌翼による被撹拌物の混合性能は、このせん断性能と循環性能との両方の性能の掛け合わせにより評価される。   The mixing performance of the material to be stirred by the stirring blade is evaluated by multiplying both the shear performance and the circulation performance.

特開２００３−２１０９０３号公報JP 2003-210903 A 特開平 ９−１８７６３６号公報JP-A-9-187636

そこで、本発明は、かかる問題を鑑みてなされたもので、せん断性能と循環性能との両方の性能を併せ持つ撹拌翼を有する撹拌装置を提供するものである。   Therefore, the present invention has been made in view of such a problem, and provides a stirring device having a stirring blade having both the shear performance and the circulation performance.

本発明に係る撹拌装置は、被撹拌物を収容する撹拌槽と、該撹拌槽内に回転可能に取り付けられる撹拌軸と、該撹拌軸に取り付けられる撹拌翼とを備える撹拌装置であって、撹拌翼は、羽根を有し、該羽根は、羽根本体と、回転方向において開口する溝部とを有し、該溝部は、撹拌軸の軸芯を中心とする回転半径を通る方向と交差する方向に伸びることを特徴とする。   A stirrer according to the present invention is a stirrer provided with a stirrer that accommodates an object to be stirred, a stirrer that is rotatably mounted in the stirrer, and a stirring blade that is mounted on the stirrer. The blade has a blade, and the blade has a blade body and a groove portion that opens in the rotation direction, and the groove portion intersects the direction passing through the rotation radius centered on the axis of the stirring shaft. It is characterized by stretching.

かかる構成によれば、撹拌軸を回転させることにより、撹拌翼の羽根は、撹拌槽内を回転して、溝部で被撹拌物をせん断する。さらに、回転する撹拌翼の羽根は、溝部で受けた被撹拌物を溝部に沿って撹拌軸の軸芯方向に向けて流動させることにより、撹拌槽内の被撹拌物の循環にも寄与する。よって、この撹拌翼は、せん断性能と循環性能との両方の性能を併せ持つ。   According to this configuration, by rotating the stirring shaft, the blades of the stirring blade rotate in the stirring tank and shear the object to be stirred in the groove. Further, the blades of the rotating stirring blades contribute to circulation of the stirring object in the stirring tank by causing the stirring object received in the groove part to flow along the groove part in the axial direction of the stirring shaft. Therefore, this stirring blade has both performance of shear performance and circulation performance.

また、本実施形態に係る撹拌装置の一態様として、溝部は、回転軌道上における撹拌軸の軸芯方向に対して回転方向に所定角度で傾斜することが好ましい。   Moreover, as an aspect of the stirring device according to the present embodiment, the groove portion is preferably inclined at a predetermined angle in the rotational direction with respect to the axial direction of the stirring shaft on the rotational track.

かかる構成によれば、溝部で受けた被撹拌物が撹拌軸の軸芯方向に対して回転方向に傾斜した溝部の方向に沿って流動することにより、溝部に加わる抵抗が低くなり、撹拌槽内における被撹拌物の循環を起こしやすくなる。   According to this configuration, the object to be stirred received in the groove portion flows along the direction of the groove portion inclined in the rotational direction with respect to the axial direction of the stirring shaft, so that the resistance applied to the groove portion is reduced, and the inside of the stirring tank is reduced. It becomes easy to cause the circulation of the object to be stirred in.

また、本実施形態に係る撹拌装置の他態様として、溝部は、断面視半円状に形成されていることが好ましい。   Moreover, as another aspect of the stirring device according to the present embodiment, the groove is preferably formed in a semicircular shape in cross-sectional view.

かかる構成によれば、溝部は、被撹拌物を中央に寄せつつ、撹拌軸の軸芯方向に向けて流動させることができ、被撹拌物を撹拌軸の径方向に向かって流動しにくくなり、撹拌槽内における被撹拌物の循環を促進する。   According to such a configuration, the groove portion can flow toward the axial center direction of the stirring shaft while bringing the stirring target to the center, and the stirring target is less likely to flow toward the radial direction of the stirring shaft. Promotes circulation of the object to be stirred in the stirring tank.

また、本実施形態に係る撹拌装置の他態様として、撹拌翼は、撹拌軸に対して２段以上設けることが好ましい。   Moreover, as another aspect of the stirring apparatus according to the present embodiment, the stirring blade is preferably provided in two or more stages with respect to the stirring shaft.

かかる構成によれば、撹拌槽内における被撹拌物の撹拌軸方向の循環性能を高めることができ、高容量の撹拌槽や高粘度の被撹拌物にも対応できる。   According to this configuration, the circulation performance of the stirring object in the stirring axis direction in the stirring tank can be enhanced, and it can be applied to a high-capacity stirring tank and a highly viscous stirred object.

また、本実施形態に係る撹拌装置の他態様として、各撹拌翼は、該各撹拌翼の羽根が撹拌軸の周方向における他の撹拌翼の羽根の位置から同方向にずれた位置に配置されるように、撹拌軸に取り付けられることが好ましい。   As another aspect of the stirring device according to this embodiment, each stirring blade is disposed at a position where the blade of each stirring blade is shifted in the same direction from the position of the blade of the other stirring blade in the circumferential direction of the stirring shaft. As such, it is preferably attached to the stirring shaft.

かかる構成によれば、撹拌槽内における被撹拌物の撹拌軸方向の流れに合わせて、各撹拌翼の羽根を配置することにより、被撹拌物の撹拌軸方向の流れが円滑になるように制御することができる。   According to this configuration, the flow of the stirring object in the stirring axis direction is controlled by arranging the blades of the stirring blades in accordance with the flow of the stirring object in the stirring tank in the stirring axis direction. can do.

また、本実施形態に係る撹拌装置の他態様として、各撹拌翼は、他の撹拌翼の羽根の回転半径と異なる回転半径の羽根を有することが好ましい。   Moreover, as another aspect of the stirring apparatus according to the present embodiment, each stirring blade preferably has blades having a rotation radius different from the rotation radius of the blades of the other stirring blades.

かかる構成によれば、撹拌槽内における被撹拌物の撹拌軸方向の流れに合わせて、各撹拌翼の羽根の回転半径を変えることにより、被撹拌物の撹拌軸方向の流れが促進されるように制御することができる。   According to such a configuration, the flow of the stirring object in the stirring axis direction is promoted by changing the rotation radius of the blade of each stirring blade in accordance with the flow of the stirring object in the stirring tank in the stirring axis direction. Can be controlled.

以上の如く、本発明によれば、せん断性能と循環性能との両方の性能を併せ持つ撹拌翼を有する。   As described above, according to the present invention, the stirring blade having both the shear performance and the circulation performance is provided.

以下、本発明の第１実施形態に係る撹拌装置について、図１〜図３を参照して説明する。同実施形態に係る撹拌装置１は、竪型撹拌装置であり、被撹拌物を収容する撹拌槽２と、該撹拌槽２内に回転可能に取り付けられる撹拌軸３と、該撹拌軸３に取り付けられる撹拌翼４と、撹拌軸３を駆動する駆動部５とを備える。本実施形態に係る被撹拌物としては、液体Ｌを例に説明するが、これに限定されず、被撹拌物には、高粘度の液状物なども含まれる。   Hereinafter, the stirring device according to the first embodiment of the present invention will be described with reference to FIGS. The stirring device 1 according to the embodiment is a vertical stirring device, and includes a stirring tank 2 that accommodates an object to be stirred, a stirring shaft 3 that is rotatably mounted in the stirring tank 2, and a stirring shaft 3 that is attached to the stirring shaft 3. The stirring blade 4 and the drive part 5 which drives the stirring shaft 3 are provided. Although the liquid L is demonstrated to an example as a to-be-stirred object which concerns on this embodiment, it is not limited to this, A high-viscosity liquid material etc. are also contained in a to-be-stirred object.

撹拌槽２は、縦方向に長い円筒形状の撹拌槽である。撹拌槽２は、円筒状の直胴部２１と、該直胴部２１の下端に取り付けられる断面形状が半楕円形状の底部２２と、直胴部２１の上端に取り付けられる断面形状が半楕円形状の頂部２３とを備える。撹拌槽２は、軸芯が垂直となるように保持される。   The stirring tank 2 is a cylindrical stirring tank that is long in the vertical direction. The stirring tank 2 includes a cylindrical straight body portion 21, a bottom portion 22 having a semi-elliptical cross section attached to the lower end of the straight body portion 21, and a semi-elliptical cross section shape attached to the upper end of the straight body portion 21. The top 23 is provided. The stirring tank 2 is held so that the axis is vertical.

撹拌軸３は、撹拌槽２の中心軸上に配置される。そして、撹拌軸３は、下端側が撹拌槽２の底部２２に設けられる軸受（図示しない）を介して支持される。さらに、撹拌軸３は、上端側が撹拌槽２の上部より上方に設けられる駆動部５（ここでは、モータとする）に接続され、周方向Ａに回転可能に構成される。なお、撹拌軸３は、下端側がどこにも支持されず、撹拌槽２内に有してもよい。また、駆動部５が撹拌槽２の下部より下方に設けられ、駆動部５が撹拌軸３の下端側と接続されるようにしてもよい。   The stirring shaft 3 is disposed on the central axis of the stirring tank 2. And the stirring shaft 3 is supported via the bearing (not shown) in which the lower end side is provided in the bottom part 22 of the stirring tank 2. FIG. Further, the agitation shaft 3 is connected to a drive unit 5 (here, a motor) provided at the upper end side above the upper part of the agitation tank 2, and is configured to be rotatable in the circumferential direction A. Note that the lower end side of the stirring shaft 3 is not supported anywhere and may be provided in the stirring tank 2. Alternatively, the drive unit 5 may be provided below the lower part of the stirring tank 2, and the drive unit 5 may be connected to the lower end side of the stirring shaft 3.

撹拌翼４は、撹拌軸３に取り付け可能な円筒状のボス４１と、該ボス４１から撹拌軸３の径方向に突出するサポートアーム４２と、該サポートアーム４２の先端部に取り付けられる羽根４３とを備える。ボス４１、サポートアーム４２及び羽根４３とは、それぞれ溶接等により固定されている。   The stirring blade 4 includes a cylindrical boss 41 that can be attached to the stirring shaft 3, a support arm 42 that protrudes from the boss 41 in the radial direction of the stirring shaft 3, and a blade 43 that is attached to the tip of the support arm 42. Is provided. The boss 41, the support arm 42, and the blades 43 are fixed by welding or the like.

ボス４１は、円筒形状をしており、撹拌軸３の下端部に挿通される貫通孔４１ａを有する。撹拌翼４は、このボス４１の貫通孔４１ａに撹拌軸３を挿通し、ねじ締結又は溶接等により撹拌軸３に取り付けられる。   The boss 41 has a cylindrical shape and has a through hole 41 a that is inserted into the lower end of the stirring shaft 3. The stirring blade 4 is attached to the stirring shaft 3 by inserting the stirring shaft 3 into the through hole 41a of the boss 41 and screwing or welding.

サポートアーム４２は、ボス４１の外周面から径方向に突出して設けられる。サポートアーム４２は、ボス４１の周方向に等間隔に設けられる。具体的には、サポートアーム４２は、３つ設けられており、３つのサポートアーム４２は、ボス４１の周方向に撹拌軸３を中心に１２０度間隔に設けられている。サポートアーム４２の形状は、長尺状で且つ平板状に形成されており、基端側（撹拌軸３側）がボス４１に接続され、先端側（撹拌槽２の内側面側）が羽根４３に接続される。   The support arm 42 is provided so as to protrude in the radial direction from the outer peripheral surface of the boss 41. The support arms 42 are provided at equal intervals in the circumferential direction of the boss 41. Specifically, three support arms 42 are provided, and the three support arms 42 are provided at intervals of 120 degrees around the stirring shaft 3 in the circumferential direction of the boss 41. The shape of the support arm 42 is a long and flat plate, the base end side (stirring shaft 3 side) is connected to the boss 41, and the tip end side (inner side surface side of the stirring tank 2) is a blade 43. Connected to.

また、サポートアーム４２は、平面が撹拌軸３の軸芯方向に対して直交するようにボス４１に固定されている。しかし、長尺状で且つ平板状に形成されたサポートアーム４２の側面、上面又は下面は、水平面から傾斜していてもよい。撹拌槽２内で長尺方向が略水平方向となるようにサポートアーム４２が配置されたときに、横方向に向いた面がサポートアーム４２の側面であり、上方向に向いた面がサポートアーム４２の上面であり、下方向に向いた面がサポートアーム４２の下面である。これにより、サポートアーム４２が撹拌槽２内に満たされた液体Ｌやスラリー（被撹拌物）の中から抜き出される際に、液体Ｌやスラリーがサポートアーム４２の側面、上面又は下面を伝って垂れ易くなり、液体Ｌやスラリーがサポートアーム４２の表面に残留しない。サポートアーム４２の形状は、棒状であってもよいし、柱状であってもよい。   Further, the support arm 42 is fixed to the boss 41 so that the plane is orthogonal to the axial direction of the stirring shaft 3. However, the side surface, upper surface, or lower surface of the long and flat support arm 42 may be inclined from the horizontal plane. When the support arm 42 is arranged so that the longitudinal direction is substantially horizontal in the agitation tank 2, the laterally facing surface is the side surface of the support arm 42, and the upwardly facing surface is the support arm. The upper surface of 42 and the surface facing downward is the lower surface of the support arm 42. Thereby, when the support arm 42 is extracted from the liquid L or slurry (object to be stirred) filled in the stirring tank 2, the liquid L or slurry travels along the side surface, upper surface or lower surface of the support arm 42. The liquid L and the slurry do not remain on the surface of the support arm 42. The shape of the support arm 42 may be a rod shape or a column shape.

羽根４３は、半円筒形状に形成されている。羽根４３は、一端から他端まで同一径で形成されており、つまり、羽根４３の幅が一定である。羽根４３は、サポートアーム４２が取り付けられる羽根本体４４と、該羽根本体４４の回転方向Ｂにおいて開口する溝部４５とを有する。羽根本体４４は、溝部４５が回転方向Ｂ（羽根４３が旋回する旋回方向Ｂ）に開口するように、サポートアーム４２に取り付けられる。また、羽根本体４４は、筒芯方向Ｅの略中間位置でサポートアーム４２に取り付けられている。溝部４５は、撹拌軸３の軸芯を中心とする回転半径を通る方向Ｄと直交する方向Ｅに伸びる。本実施形態においては、溝部４５は、撹拌軸３の軸芯方向に沿って平行に形成されており、つまり、上下方向に形成されている。溝部４５は、羽根本体４４の回転方向Ｂに向いた面を窪ませて形成されており、断面視半円状に形成された溝であり、よって、羽根４３全体は、断面視半円弧状に形成されている。溝部４５は、羽根本体４４における筒芯方向Ｅの一端から他端まで連続して形成されている。そのため、筒芯方向Ｅにおける溝部４５の両端は、開放している。   The blades 43 are formed in a semi-cylindrical shape. The blades 43 are formed with the same diameter from one end to the other end, that is, the width of the blades 43 is constant. The blade 43 includes a blade body 44 to which the support arm 42 is attached, and a groove 45 that opens in the rotation direction B of the blade body 44. The blade body 44 is attached to the support arm 42 so that the groove 45 opens in the rotation direction B (the turning direction B in which the blade 43 turns). The blade body 44 is attached to the support arm 42 at a substantially intermediate position in the cylinder core direction E. The groove 45 extends in a direction E perpendicular to the direction D passing through the radius of rotation about the axis of the stirring shaft 3. In this embodiment, the groove part 45 is formed in parallel along the axial direction of the stirring shaft 3, that is, is formed in the vertical direction. The groove 45 is formed by recessing the surface of the blade main body 44 facing the rotation direction B, and is a groove formed in a semicircular shape in cross section. Therefore, the entire blade 43 has a semicircular shape in cross section. Is formed. The groove portion 45 is formed continuously from one end to the other end in the tube core direction E of the blade body 44. Therefore, both ends of the groove 45 in the tube core direction E are open.

次に、この本実施形態に係る撹拌装置１の作用について説明する。まず、撹拌装置１の駆動部５を駆動して撹拌軸３を回転させると、撹拌翼４が撹拌槽２内を撹拌軸３を中心に回転し、溝部４５で液体Ｌをせん断する。溝部４５で液体Ｌを受けて、溝部４５に沿って液体Ｌを軸芯方向Ｃ（上下方向）に流動させる。具体的には、撹拌翼４は、液体Ｌを溝部４５に沿って下方に向けて流動させる。液体Ｌは、撹拌槽２の底部で流れを外側に転回し、撹拌槽２の側壁で上方に転回し、撹拌槽２の上部で内側に転回し、撹拌槽２の中心部で下方に転回し、再び撹拌翼４に戻る。液体Ｌは、このように撹拌槽２内を循環する。   Next, the operation of the stirring device 1 according to this embodiment will be described. First, when the drive unit 5 of the stirring device 1 is driven to rotate the stirring shaft 3, the stirring blade 4 rotates around the stirring shaft 3 in the stirring tank 2 and shears the liquid L in the groove 45. The liquid L is received by the groove 45, and the liquid L flows in the axial direction C (vertical direction) along the groove 45. Specifically, the stirring blade 4 causes the liquid L to flow downward along the groove 45. The liquid L turns around at the bottom of the stirring tank 2, turns upward at the side wall of the stirring tank 2, turns inside at the top of the stirring tank 2, and turns downward at the center of the stirring tank 2. Return to the stirring blade 4 again. The liquid L circulates in the stirring tank 2 in this way.

以上、本実施形態に係る撹拌装置１は、液体Ｌを収容する撹拌槽２と、該撹拌槽２内に回転可能に取り付けられる撹拌軸３と、該撹拌軸３に取り付けられる撹拌翼４とを備え、撹拌翼４は、羽根４３を有し、該羽根４３は、羽根本体４４と、回転方向Ｂにおいて開口する溝部４５とを有し、該溝部４５は、撹拌軸３の軸芯を中心とする回転半径を通る方向Ｄと直交する方向Ｅに伸びる構成である。そのため、本実施形態に係る撹拌装置１は、撹拌軸３を回転させることにより、撹拌翼４は、撹拌槽２内を回転して、溝部４５で液体Ｌをせん断する。さらに、回転する撹拌翼４は、溝部４５で受けた液体Ｌを溝部４５に沿って撹拌軸３の軸芯方向Ｃに向けて流動させることにより、撹拌槽２内の液体Ｌの循環にも寄与する。よって、この撹拌翼４は、せん断性能と循環性能との両方の性能を併せ持つ。   As described above, the stirring device 1 according to the present embodiment includes the stirring tank 2 that stores the liquid L, the stirring shaft 3 that is rotatably mounted in the stirring tank 2, and the stirring blade 4 that is mounted on the stirring shaft 3. The stirring blade 4 includes a blade 43, the blade 43 includes a blade body 44 and a groove portion 45 opened in the rotation direction B, and the groove portion 45 is centered on the axis of the stirring shaft 3. It is the structure extended in the direction E orthogonal to the direction D which passes the rotation radius to do. Therefore, the stirring device 1 according to this embodiment rotates the stirring shaft 3 so that the stirring blade 4 rotates in the stirring tank 2 and shears the liquid L in the groove 45. Furthermore, the rotating stirring blade 4 contributes to the circulation of the liquid L in the stirring tank 2 by causing the liquid L received in the groove 45 to flow along the groove 45 in the axial direction C of the stirring shaft 3. To do. Therefore, the stirring blade 4 has both the shear performance and the circulation performance.

また、本実施形態に係る撹拌装置１において、溝部４５は、断面視半円状に形成されている構成である。そのため、本実施形態に係る撹拌装置１において、溝部４５は、液体Ｌを中央に寄せつつ、撹拌軸３の軸芯方向Ｃに向けて流動させることができ、液体Ｌを撹拌軸３の（半）径方向Ｄに向かって流動しにくくなっている。また、溝部４５は、液体Ｌを撹拌軸３の軸芯方向Ｃに流動させながら、液体Ｌを溝部４５の中央に寄せて液体Ｌにかかる圧力を上げ、溝部４５に沿って流動していた液体Ｌが溝部４５から吐出される際に、液体Ｌの圧力が一気に解放されることで、液体Ｌの撹拌反応が促進される。   Moreover, in the stirring apparatus 1 which concerns on this embodiment, the groove part 45 is the structure formed in the cross sectional view semicircle shape. Therefore, in the stirring device 1 according to the present embodiment, the groove portion 45 can flow the liquid L in the axial direction C of the stirring shaft 3 while bringing the liquid L to the center. ) It is difficult to flow in the radial direction D. Further, the groove 45 moves the liquid L toward the center of the groove 45 while increasing the pressure applied to the liquid L while causing the liquid L to flow in the axial direction C of the stirring shaft 3, and the liquid flowing along the groove 45. When L is discharged from the groove 45, the pressure of the liquid L is released at a stretch, and the stirring reaction of the liquid L is promoted.

また、本実施形態に係る撹拌装置１において、羽根４３は、サポートアーム４２の先端側に取り付けられ、撹拌軸３から（半）径方向Ｄに離間した位置に取り付けられている構成である。そのため、本実施形態に係る撹拌装置１は、撹拌翼４が液体Ｌをせん断するせん断面が撹拌槽２の（半）径方向Ｄに占める面積の一部にすぎず、撹拌翼４を回転させるために撹拌軸３を回転させる動力が低く抑えられる。   Further, in the stirring device 1 according to the present embodiment, the blade 43 is attached to the distal end side of the support arm 42 and is attached to a position separated from the stirring shaft 3 in the (half) radial direction D. Therefore, in the stirring device 1 according to the present embodiment, the shear surface on which the stirring blade 4 shears the liquid L is only a part of the area occupied in the (semi) radial direction D of the stirring tank 2 and rotates the stirring blade 4. Therefore, the power for rotating the stirring shaft 3 can be kept low.

次に、本発明の第２実施形態に係る撹拌装置について、図４〜図６を参照しつつ説明する。なお、本実施形態に係る撹拌装置と第１実施形態に係る撹拌装置１とが異なる点は、撹拌翼の形状であり、それ以外については、基本的に同じであるため、同じ構成については同じ符号を採番し、その説明は繰り返さない。   Next, a stirring device according to a second embodiment of the present invention will be described with reference to FIGS. The difference between the stirrer according to the present embodiment and the stirrer 1 according to the first embodiment is the shape of the stirrer blade, and the rest is basically the same, and therefore the same configuration is the same. Numbers are assigned and the description is not repeated.

本実施形態に係る撹拌翼４は、第１実施形態の羽根４３と異なる羽根１４３を有し、該羽根１４３は、回転軌道上における撹拌軸３の軸芯方向Ｃに対して回転方向Ｂに所定角度αで傾斜する（図６参照）。具体的には、羽根１４３は、第１実施形態と同様に、羽根本体１４４と溝部１４５とを有する。羽根本体１４４は、筒芯方向Ｅの略中間位置でサポートアーム４２に取り付けられており、この筒芯方向Ｅの略中間位置を中心に、撹拌軸３の軸芯方向Ｃにおける上端側を旋回方向Ｆ１に傾斜させ（回転させ）、撹拌軸３の軸芯方向における下端側を旋回方向Ｆ１と逆方向Ｆ２に傾斜させた（回転させた）姿勢でサポートアーム４２に取り付けられている。   The stirring blade 4 according to the present embodiment has a blade 143 different from the blade 43 of the first embodiment, and the blade 143 is predetermined in the rotation direction B with respect to the axial direction C of the stirring shaft 3 on the rotation path. It tilts at an angle α (see FIG. 6). Specifically, the blade 143 includes a blade body 144 and a groove portion 145 as in the first embodiment. The blade main body 144 is attached to the support arm 42 at a substantially intermediate position in the cylinder core direction E, and the upper end side in the axial direction C of the stirring shaft 3 is swiveled around the substantially intermediate position in the cylinder core direction E. It is attached to the support arm 42 in a posture in which the lower end side in the axial direction of the stirring shaft 3 is inclined (rotated) in the direction F2 opposite to the turning direction F1.

溝部１４５は、回転軌道上における撹拌軸３の軸芯方向Ｃに対して回転方向Ｂに所定角度αで傾斜する。溝部１４５の所定角度αは、４５度以下の範囲の角度で傾斜する。なお、溝部１４５は、羽根１４３自体を傾斜させることにより、傾斜しているが、溝部１４５のみが傾斜していてもよい。また、溝部１４５は、回転方向Ｂにおいて斜め下方に開口する。よって、溝部１４５は、液体Ｌを斜め下方に流動させる。溝部１４５は、断面視半円状に形成されており、羽根１４３自体は、断面視円弧状に形成されている。溝部１４５がせん断するせん断面積は、羽根１４３の旋回方向と逆方向Ｆ２側（撹拌軸３の回転方向Ｂと反対側）から見た投影面積に相当する。なお、撹拌槽２内の液体Ｌの循環流によりせん断面積は変わり得る。   The groove portion 145 is inclined at a predetermined angle α in the rotation direction B with respect to the axial direction C of the stirring shaft 3 on the rotation path. The predetermined angle α of the groove 145 is inclined at an angle in the range of 45 degrees or less. In addition, although the groove part 145 inclines by inclining blade | wing 143 itself, only the groove part 145 may incline. The groove 145 opens obliquely downward in the rotation direction B. Accordingly, the groove 145 causes the liquid L to flow obliquely downward. The groove portion 145 is formed in a semicircular shape in cross section, and the blade 143 itself is formed in an arc shape in cross section. The shear area that the groove 145 shears corresponds to the projected area as viewed from the direction F2 opposite to the swirl direction of the blade 143 (on the side opposite to the rotation direction B of the stirring shaft 3). The shear area can be changed by the circulating flow of the liquid L in the stirring tank 2.

以上、本実施形態に係る撹拌装置１は、撹拌翼４の溝部１４５は、回転軌道上における撹拌軸３の軸芯方向Ｃに対して回転方向Ｂに所定角度αで傾斜する構成である。そのため、本実施形態に係る撹拌装置１は、溝部１４５で受けた液体Ｌが撹拌軸３の軸芯方向Ｃに対して回転方向Ｂに傾斜した溝部１４５の方向に沿って流動することにより、溝部１４５に加わる抵抗が低くなり、撹拌槽２内における液体Ｌの循環を起こしやすくなる。   As described above, the stirring device 1 according to the present embodiment is configured such that the groove portion 145 of the stirring blade 4 is inclined at the predetermined angle α in the rotation direction B with respect to the axial direction C of the stirring shaft 3 on the rotation path. Therefore, the stirring device 1 according to the present embodiment causes the liquid L received by the groove 145 to flow along the direction of the groove 145 inclined in the rotation direction B with respect to the axial direction C of the stirring shaft 3. The resistance applied to 145 is lowered, and the liquid L is easily circulated in the stirring tank 2.

なお、本発明に係る撹拌装置は、上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の変更を加えることができる。   In addition, the stirring apparatus which concerns on this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the summary of this invention.

上記実施形態に係る撹拌装置１は、撹拌翼４を構成する羽根４３，１４３の枚数が３つである例を説明したが、これに限定されるものではない。例えば、撹拌軸に取り付けられる撹拌翼の枚数は、２枚であってもよいし、４枚以上であってもよい。また、撹拌翼は、撹拌軸の周方向において、２枚又は４枚以上の羽根が撹拌軸を中心に一定の角度をあけて配置されていてもよい。つまり、各羽根が撹拌軸の周方向に略等間隔離間させて設けられていてもよい。   Although the stirring apparatus 1 which concerns on the said embodiment demonstrated the example in which the number of the blade | wings 43 and 143 which comprise the stirring blade 4 was three, it is not limited to this. For example, the number of stirring blades attached to the stirring shaft may be two, or four or more. Further, in the circumferential direction of the stirring shaft, two or four or more blades may be arranged at a constant angle around the stirring shaft. That is, the blades may be provided at substantially equal intervals in the circumferential direction of the stirring shaft.

また、一つの撹拌翼は、１又は複数の羽根を有する撹拌翼を複数組み合わせて、所定の枚数の羽根を有するものであってもよい。具体的には、一つの撹拌翼に４枚の羽根が必要な場合、２枚の羽根を有する撹拌翼を２つ重ね合わせることにより、４枚の羽根を有する一つの撹拌翼を形成してもよい。   One stirring blade may have a predetermined number of blades by combining a plurality of stirring blades having one or a plurality of blades. Specifically, when four blades are required for one stirring blade, two stirring blades having two blades are overlapped to form one stirring blade having four blades. Good.

上記実施形態に係る撹拌装置１は、撹拌翼４に設けられた羽根４３，１４３が撹拌軸３の周方向に互いに等間隔に配置される例を説明したが、これに限定されるものではない。例えば、４枚の羽根が設けられた撹拌翼４が撹拌軸３の周方向に撹拌軸３を中心に６０度、１２０度、１８０度、２４０度の位置に設けられていてもよい。つまり、各羽根が撹拌軸の周方向に略等間隔離間させて設けられていなくてもよい。   Although the stirring apparatus 1 which concerns on the said embodiment demonstrated the example in which the blade | wings 43 and 143 provided in the stirring blade 4 are mutually arrange | positioned at equal intervals in the circumferential direction of the stirring shaft 3, it is not limited to this. . For example, the stirring blade 4 provided with four blades may be provided at positions of 60 degrees, 120 degrees, 180 degrees, and 240 degrees around the stirring shaft 3 in the circumferential direction of the stirring shaft 3. That is, the blades need not be provided at substantially equal intervals in the circumferential direction of the stirring shaft.

また、図７に示すように、この２つの撹拌翼４，４が、撹拌軸３に対して２段以上設けられていてもよく、つまり、撹拌軸３の軸芯方向Ｃに所定間隔離間させて２か所以上設けられていてもよい。この撹拌軸３の軸芯方向Ｃにおける２つの撹拌翼４，４の位置は、撹拌する対象である液体Ｌの性状、撹拌槽２内における液体Ｌの上面の高さ（被撹拌物が液体である場合における液面）などにより、下端部に偏って配置され、又は、軸芯方向Ｃに等間隔に配置される。そのため、撹拌槽２内における液体Ｌの撹拌軸３の軸芯方向Ｃの循環性能を高めることができ、撹拌槽２内の液体Ｌの流動状態が向上する。また、高容量の撹拌槽２や高粘度の液体Ｌにも対応できるようになる。   In addition, as shown in FIG. 7, the two stirring blades 4 and 4 may be provided in two or more stages with respect to the stirring shaft 3, that is, separated by a predetermined interval in the axial direction C of the stirring shaft 3. Two or more locations may be provided. The positions of the two stirring blades 4 and 4 in the axial direction C of the stirring shaft 3 are the properties of the liquid L to be stirred, the height of the upper surface of the liquid L in the stirring tank 2 (the object to be stirred is liquid) Depending on the liquid level in a certain case, it is biased toward the lower end portion or at equal intervals in the axial direction C. Therefore, the circulation performance of the liquid L in the stirring tank 2 in the axial direction C of the stirring shaft 3 can be improved, and the flow state of the liquid L in the stirring tank 2 is improved. Moreover, it becomes possible to cope with a high-capacity stirring tank 2 and a high-viscosity liquid L.

また、図１２に示すように、撹拌軸３の軸芯方向に複数の撹拌翼４が設けられ、各撹拌翼４は、該各撹拌翼４の羽根１４３ａ〜１４３ｅが撹拌軸３の周方向における他の撹拌翼４の羽根１４３ａ〜１４３ｅの位置から同方向にずれた位置に配置されるように、撹拌軸３に取り付けられていてもよい。また、各撹拌翼４の羽根１４３ａ〜１４３ｅは、撹拌軸３の周方向Ｂにおける他の撹拌翼４の羽根１４３ａ〜１４３ｅの位置から同方向にずれた位置に配置されていてもよい。つまり、撹拌翼４相互の羽根１４３ａ〜１４３ｅの位置（位相）が撹拌軸３の軸芯方向視において位置ずれしていてもよい。   As shown in FIG. 12, a plurality of stirring blades 4 are provided in the axial direction of the stirring shaft 3, and each stirring blade 4 has blades 143 a to 143 e in the circumferential direction of the stirring shaft 3. You may attach to the stirring shaft 3 so that it may be arrange | positioned in the position which shifted | deviated from the position of the blade | wings 143a-143e of the other stirring blade 4 to the same direction. Further, the blades 143 a to 143 e of each stirring blade 4 may be arranged at positions shifted in the same direction from the positions of the blades 143 a to 143 e of the other stirring blade 4 in the circumferential direction B of the stirring shaft 3. That is, the positions (phases) of the blades 143a to 143e between the stirring blades 4 may be displaced in the axial direction of the stirring shaft 3.

例えば、最上段である１段目の撹拌翼４の羽根１４３ａの周方向Ｂにおける位置に対して、２段目の撹拌翼４の羽根１４３ｂは、撹拌軸３の旋回方向（周方向）Ｂに２５度回転した位置に設けられていてもよい。３段目の撹拌翼４の羽根１４３ｃは、２段目の撹拌翼４の羽根１４３ｂの周方向Ｂにおける位置に対して、撹拌軸３の旋回方向Ｂに２５度回転した位置に設けられていてもよい。４段目及び５段目の撹拌翼４の羽根１４３ｄ，１４３ｅについても同様である。つまり、各撹拌翼４の羽根１４３ａ〜１４３ｅは、撹拌軸３を中心に螺旋状に配置されていてもよい。なお、各撹拌翼４の羽根は、渦巻状に配置されていてもよい。   For example, the blade 143b of the second stage stirring blade 4 in the turning direction (circumferential direction) B of the stirring shaft 3 with respect to the position in the circumferential direction B of the blade 143a of the first stage stirring blade 4 which is the uppermost stage. It may be provided at a position rotated by 25 degrees. The blade 143c of the third stage stirring blade 4 is provided at a position rotated by 25 degrees in the turning direction B of the stirring shaft 3 with respect to the position in the circumferential direction B of the blade 143b of the second stage stirring blade 4. Also good. The same applies to the blades 143d and 143e of the fourth and fifth stirring blades 4. That is, the blades 143a to 143e of each stirring blade 4 may be arranged in a spiral shape with the stirring shaft 3 as the center. In addition, the blade | wing of each stirring blade 4 may be arrange | positioned at the spiral shape.

そのため、撹拌槽２内における液体Ｌ（被撹拌物）の撹拌軸方向（上下方向）の流れに合わせて、各撹拌翼４の羽根１４３ａ〜１４３ｅを配置することにより、液体Ｌの撹拌軸方向の流れが円滑になるように制御することができ、撹拌槽２内の液体Ｌの流動状態が向上する。   Therefore, by arranging the blades 143a to 143e of the stirring blades 4 in accordance with the flow in the stirring axis direction (vertical direction) of the liquid L (object to be stirred) in the stirring tank 2, the liquid L in the stirring axis direction is arranged. The flow can be controlled to be smooth, and the flow state of the liquid L in the agitation tank 2 is improved.

なお、撹拌翼４相互の撹拌軸３の周方向Ｂにおける羽根１４３ａ〜１４３ｅが２５度ずつ位置ずれしている例を図１２に示したが、これに限定されるものではない。例えば、周方向Ｂにおける羽根が９０度ずつ位置ずれしていてもよいし、これ以外の角度であってもよい。また、羽根が周方向に位置ずれしていなくてもよい。   In addition, although the example in which the blades 143a to 143e in the circumferential direction B of the stirring shaft 4 between the stirring blades 4 are displaced by 25 degrees is shown in FIG. 12, it is not limited to this. For example, the blades in the circumferential direction B may be displaced by 90 degrees, or may be at an angle other than this. Further, the blades do not have to be displaced in the circumferential direction.

また、図１３及び図１４に示すように、撹拌軸３の軸芯方向Ｃに複数の撹拌翼４が設けられ、一方の撹拌翼４の羽根１４３の溝部が回転軌道Ｂ上における撹拌軸３の軸芯方向Ｃに対して回転方向Ｂに所定角度で傾斜しており、他方の撹拌翼４の羽根４３の溝部が回転軌道Ｂ上における撹拌軸３の軸芯方向Ｃに対して回転方向Ｂに傾斜していなくてもよい。特に、上段の撹拌翼４の溝部が傾斜しており、下段の撹拌翼４が傾斜していないことが好ましい。更に、最下段の撹拌翼４が傾斜していないことが好ましい。これにより、上段の撹拌翼４が液体Ｌの巻き込みを促進し、下段又は最下段の撹拌翼４が液体Ｌの吐出を促進し、撹拌槽２内の液体Ｌの流動状態が向上する。   Further, as shown in FIGS. 13 and 14, a plurality of stirring blades 4 are provided in the axial direction C of the stirring shaft 3, and the groove portion of the blade 143 of one stirring blade 4 is arranged on the rotation path B of the stirring shaft 3. The groove portion of the blade 43 of the other stirring blade 4 is inclined in the rotational direction B with respect to the axial direction C of the stirring shaft 3 on the rotational track B. It does not have to be inclined. In particular, it is preferable that the groove portion of the upper stirring blade 4 is inclined and the lower stirring blade 4 is not inclined. Furthermore, it is preferable that the lowermost stirring blade 4 is not inclined. Thereby, the upper stirring blade 4 promotes the entrainment of the liquid L, the lower or lowermost stirring blade 4 promotes the discharge of the liquid L, and the flow state of the liquid L in the stirring tank 2 is improved.

また、図１５に示すように、各撹拌翼４は、他の撹拌翼４の羽根４３の回転半径と異なる回転半径の羽根４３を有していてもよい。特に、上段の撹拌翼４から下段の撹拌翼４に向かうにつれて回転半径が大きくなるか小さくなることが好ましい。これにより、撹拌槽２内における液体Ｌ（被撹拌物）の撹拌軸方向の流れに合わせて、各撹拌翼４の羽根４３の回転半径を変えることにより、液体Ｌの撹拌軸方向の流れが促進されるように制御することができる。   Further, as shown in FIG. 15, each stirring blade 4 may have a blade 43 having a rotation radius different from the rotation radius of the blade 43 of the other stirring blade 4. In particular, it is preferable that the radius of rotation increases or decreases from the upper stirring blade 4 toward the lower stirring blade 4. Thereby, the flow of the liquid L in the stirring axis direction is promoted by changing the rotation radius of the blade 43 of each stirring blade 4 in accordance with the flow of the liquid L (agitated object) in the stirring tank 2 in the stirring axis direction. Can be controlled.

上記実施形態に係る撹拌装置１は、羽根４３，１４３自体が断面視半円孤状（Ｃ字状）であり、溝部４５，１４５が断面視半円状である例を説明したが、これに限定されるものではない。例えば、溝部は、断面視半楕円形状であってもよい。また、羽根自体は、断面視において中心角が１８０度以上の円弧状であってもよいし、１８０度以下の円弧状であってもよい。つまり、中心角が１８０度に限定されない。溝部の形状は、曲面でなくてもよく、矩形状であってもよい。例えば、溝部は、断面視三角形状であってもよいし、断面視（長）方形状や断面視台形状であってもよい。   In the stirring device 1 according to the above embodiment, the blades 43 and 143 themselves have a semicircular arc shape (C shape) in cross section, and the grooves 45 and 145 have a semicircular shape in cross section. It is not limited. For example, the groove may have a semi-elliptical shape in cross section. Further, the blade itself may have an arc shape with a central angle of 180 degrees or more in a cross-sectional view, or may have an arc shape of 180 degrees or less. That is, the central angle is not limited to 180 degrees. The shape of the groove portion may not be a curved surface, but may be a rectangular shape. For example, the groove portion may have a triangular shape in cross-sectional view, or may have a cross-sectional view (long) square shape or a cross-sectional view trapezoidal shape.

また、羽根自体が断面視Ｖ字形状であってもよい。より具体的には、図８に示すように、断面視Ｖ字形状の羽根２４３は、幅方向の長さが略同一の板状の一対の基材２４４，２４４の端同士をＶ字状に継ぎ合わせて形成されていてもよい。このとき、溝部は、回転方向Ｂに開口していてもよいし、回転方向Ｂから径方向Ｄに向いていてもよい。   Further, the blade itself may be V-shaped in cross section. More specifically, as shown in FIG. 8, the vane 243 having a V-shaped cross-sectional view has a pair of plate-like base materials 244 and 244 having substantially the same length in the width direction, and the ends of the pair of base materials 244 and 244 are V-shaped. It may be formed by joining. At this time, the groove portion may be opened in the rotation direction B, or may be directed from the rotation direction B to the radial direction D.

また、図９に示すように、羽根３４３は、幅方向の長さが短い第１基材３４４の端と、幅方向の長さが長い第２基材３４５の端とをＶ字状に継ぎ合わせて形成されていてもよい。この場合、第１基材３４４が径方向Ｄの外側に配置され、第２基材３４５が径方向Ｄの内側に配置される方が好ましい。第１基材３４４の幅方向の長さが第２基材３４５の幅方向の長さよりも短いため、径方向Ｄの先端部における抵抗が低減される。そのため、第１基材３４４の幅方向の長さと第２基材３４５の幅方向の長さとが同じ場合と比べて、同じ回転トルクで撹拌翼４の回転数が高くなり、撹拌翼４に付着する液体Ｌが減少する。   Further, as shown in FIG. 9, the blade 343 joins the end of the first base material 344 having a short length in the width direction and the end of the second base material 345 having a long length in the width direction in a V shape. They may be formed together. In this case, it is preferable that the first base material 344 is disposed outside the radial direction D and the second base material 345 is disposed inside the radial direction D. Since the length in the width direction of the first base material 344 is shorter than the length in the width direction of the second base material 345, the resistance at the distal end portion in the radial direction D is reduced. Therefore, compared with the case where the length in the width direction of the first base material 344 and the length in the width direction of the second base material 345 are the same, the rotational speed of the stirring blade 4 becomes the same with the same rotational torque, and adheres to the stirring blade 4. Liquid L to be reduced.

更に、図１０に示すように、羽根４４３は、表裏を貫通して被撹拌物を裏側に逃がす一対の貫通孔４４６，４４６を有してもよい。具体的には、羽根４４３は、羽根本体４４４と、該羽根本体４４４の回転方向Ｂにおいて開口する溝部４４５と、羽根本体４４４を貫通して形成される一対の貫通孔４４６，４４６とを有する。羽根本体４４４は、図８に示す羽根２４３と同様に、幅方向Ｇの長さが略同一の板状の一対の基材４４７，４４７の端同士をＶ字状に継ぎ合わせて形成され、一対の基材４４７，４４７の間に隙間を形成することにより、一対の貫通孔４４６，４４６が形成される。一対の貫通孔４４６，４４６の形状は、矩形状のスリットであって、羽根本体４４４の筒芯方向Ｈ（長手方向）における両端側から筒芯方向Ｈに向かって設けられている。なお、一対の貫通孔４４６，４４６は、図１１に示すように、幅方向の長さが異なる一対の基材５４７，５４７をＶ字状に継ぎ合わせた羽根本体５４４と溝部５４５とを有する羽根５４３に表裏を貫通して被撹拌物を裏側に逃がす一対の貫通孔５４６，５４６が形成されていてもよいし、断面視半円弧状の羽根など他の断面形状の羽根に設けられてもよい。また、一対の貫通孔４４６，４４６の形状は、矩形状のスリット以外にも、円形や楕円形状であってもよいし、貫通孔４４６の数量は、１か所であってもよいし、３か所以上であってもよい。そして、一対の貫通孔４４６，４４６の位置も羽根本体４４４の筒芯方向Ｈにおける両端側に限られず、筒芯方向Ｈにおける中間であってもよい。   Furthermore, as shown in FIG. 10, the blade 443 may have a pair of through holes 446 and 446 that penetrate the front and back surfaces and allow the object to be stirred to escape to the back side. Specifically, the blade 443 includes a blade body 444, a groove portion 445 that opens in the rotation direction B of the blade body 444, and a pair of through holes 446 and 446 that are formed through the blade body 444.
