Description

  The present invention relates to a rotating body for stirring and a stirring device for stirring, mixing, dispersing, and the like of liquids and other various fluids, and more particularly to a device capable of controlling the flow in a stirring region.

  Conventionally, for example, when two or more kinds of fluids are mixed or various powders added to the fluid are uniformly dispersed, a stirring device that rotates an impeller in the fluid has been used. The impeller is provided with, for example, propeller blades and turbine blades, and agitates by rotating a material to be stirred as a fluid by rotating. However, in general, such an impeller generates a relatively uniform flow in the axial direction or the centrifugal direction. Therefore, the impeller is not so high in stirring efficiency. There were cases where problems occurred in terms of damage resistance.

  In contrast, the inventor of the present application not only improves safety and breakage resistance by not using an impeller, but also improves the stirring efficiency by generating a complicated flow in the object to be stirred. (For example, refer to Patent Document 1).

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that in the following drawings, there are parts that are omitted or simplified for easy understanding. In addition, the shape and dimensional ratio of each part in the following drawings are not necessarily accurate.

<First Embodiment>
First, the structure of the stirring rotating body 1 according to the first embodiment of the present invention will be described. 1A is a plan view of the stirring rotator 1, FIG. 1B is a front view of the stirring rotator 1, and the side view is the same, and FIG. 1C is a stirrer. It is a bottom view of the rotary body 1 for use. As shown in these drawings, the stirring rotator 1 includes a columnar main body 10, a plurality of suction ports 12 provided on the surface of the main body 10, and a plurality of discharge ports provided on the surface of the main body 10. 14, a flow path 16 formed inside the main body 10 so as to connect the suction port 12 and the discharge port 14, and a partition member 18 provided so as to protrude from the main body 10 between the suction port 12 and the discharge port 14. And is composed of.

  The main body 10 is configured in a substantially cylindrical shape in the present embodiment, and the surface of the main body 10 is configured by a substantially circular upper surface 10a and a bottom surface 10b, and a side surface 10c that is an outer peripheral surface. At the center of the upper surface 10a of the main body 10, a connecting portion 10d to which a driving shaft 20 connected to a driving device such as a motor is connected is provided. Therefore, the stirring rotating body 1 is configured to rotate about the central axis C of the main body 10 as a rotation axis. In addition, although illustration is abbreviate | omitted, the connection part 10d is comprised so that the drive shaft 20 can be connected by known appropriate connection mechanisms, such as screwing, engagement, a clamp, for example.

  The suction port 12 is provided on the bottom surface 10b on the opposite side of the connecting portion 10d, that is, the tip side of the stirring rotating body 1. In the present embodiment, four substantially circular suction ports 12 are arranged on the circumference centered on the central axis C at equal intervals. The discharge port 14 is provided at a position on the outer side in the radial direction (centrifugal direction) of the main body 10 with respect to the suction port 12 (a position away from the central axis C in a direction perpendicular to the central axis C). In the present embodiment, four substantially circular discharge ports 14 corresponding to the respective suction ports 12 are arranged on the side surface 10c.

  The flow passage 16 is formed as a tunnel-like passage that connects one suction port 12 and one discharge port 14. Accordingly, four flow passages 16 are formed inside the main body 10. In the present embodiment, each flow passage 16 is formed so as to bend at a right angle after going straight along the direction of the central axis C from the suction port 12 and to reach the discharge port 14 after going straight in the centrifugal direction of the main body 10. ing. That is, the flow passage 16 of the present embodiment includes an axial portion 16a formed in the central axis C direction and a centrifugal direction portion 16b formed in the centrifugal direction. Further, in the present embodiment, by forming the flow passage 16 in this way, the direction of the suction port 12 becomes the central axis C direction, and the direction of the discharge port 14 becomes the centrifugal direction (direction perpendicular to the central axis C). I am doing so.

  The partition member 18 is a substantially bowl-shaped (flange-shaped) member provided so as to protrude in the centrifugal direction from the bottom surface 10b side end portion of the side surface 10c. The partition member 18 is configured in a substantially flat plate shape in the present embodiment, and is provided over the entire circumference of the side surface 10c (continuously in the circumferential direction of the main body 10). And the 1st partition surface 18a which is the surface at the side of the drive shaft 20 of the partition member 18 is comprised substantially parallel to the centrifugal direction. Further, the second partition surface 18b, which is the surface on the tip side of the partition member 18, is configured to be substantially parallel to the centrifugal direction similarly to the first partition surface 18a, and is continuous with the bottom surface 10b of the main body 10. It is configured.

  Next, the operation of the stirring rotator 1 will be described. FIG. 2A is a plan view showing the action of the stirring rotator 1, and FIG. 2B is a front view showing the action of the stirring rotator 1. The stirring rotating body 1 stirs the object to be stirred by being driven by the drive shaft 20 and rotating around the central axis C in the object to be stirred that is a fluid. When the stirring rotator 1 is immersed in the fluid and rotated, the fluid that has entered the flow passage 16 also rotates together with the stirring rotator 1. Then, centrifugal force acts on the fluid in the flow passage 16, and the fluid in the flow passage 16 flows toward the outside in the radial direction of the stirring rotor 1 as shown in FIGS. 2 (a) and 2 (b). To do.

  Since the discharge port 14 is provided on the radially outer side of the stirring rotator 1 with respect to the suction port 12, a stronger centrifugal force acts on the discharge port 14 than on the suction port 12. Accordingly, the fluid flows from the suction port 12 toward the discharge port 14 as long as the stirring rotator 1 rotates. That is, the fluid in the flow passage 16 is ejected from the discharge port 14, and the external fluid is sucked into the flow passage 16 from the suction port 12. As a result, in the fluid around the stirring rotator 1, a flow that radiates from the side surface 10 c with the discharge port 14 and a flow toward the bottom surface 10 b with the suction port 12 occur.

  Further, in the vicinity of the surface of the stirring rotator 1 (that is, the upper surface 10a, the bottom surface 10b, and the side surface 10c), the fluid rotates together with the stirring rotator 1 due to the influence of viscosity. The fluid around the rotating body 1 flows so as to spread radially from the central axis C. At this time, as shown in FIG. 2B, the fluid in the vicinity of the upper surface 10a is attracted to the jet flow from the discharge port 14 together with the fluid in the vicinity of the upper surface 10a of the side surface 10c, so that the fluid flows in the centrifugal direction. It will flow relatively smoothly. As a result, a flow from the upper side (the drive shaft 20 side) toward the upper surface 10a occurs.

  On the other hand, the fluid in the vicinity of the bottom surface 10 b is less likely to be attracted to the jet from the discharge port 14 by providing the partition member 18. Specifically, the fluid near the bottom surface 10b side of the side surface 10c is attracted to the jet flow from the discharge port 14, thereby generating a negative pressure. As shown in FIG. 2B, the jet flow from the discharge port 14 A vortex is generated between the first partition surface 18a of the partition member 18 and the first partition surface 18a. The vortex prevents the centrifugal flow in the vicinity of the bottom surface 10 b from joining the jet from the discharge port 14. Further, this vortex acts so as to weaken the flow in the centrifugal direction in the vicinity of the bottom surface 10b.

  As a result, the flow from the lower side (opposite side of the drive shaft 20) toward the bottom surface 10 b is weakened by providing the partition member 18. That is, the fluid below the stirring rotator 1 is attracted to the stirring rotator 1 not only by the suction force by the suction port 12 but also by the suction force by the jet flow from the discharge port 14, but the partition member 18 is provided. As a result, the flow is weakened by the amount by which the suction force by the jet flow from the discharge port 14 is reduced.

  FIG. 3A is a diagram illustrating an example of a usage state of the stirring rotator 1, and FIG. 3B illustrates an example of a usage state of the agitation rotator 1 a that does not include the partition member 18. FIG. In these drawings, an example in which the rotating body for stirring 1, 1 a is arranged in the object to be stirred 100 accommodated in the container 30 and is rotated by the upper driving device 40 is shown.

  As shown in these drawings, by rotating the stirring rotating bodies 1 and 1a in the object to be stirred 100, a complicated circulation flow is generated in the object to be stirred 100. That is, the flow that radially spreads in the centrifugal direction from the stirring rotator 1 and 1a due to the ejection from the discharge port 14 divides up and down after being spread to some extent, and one becomes the flow toward the stirring rotator 1a from above, and the other Will flow from below toward the stirring rotor 1a.

  In the stirring rotator 1a that does not have the partition member 18, the flow from above to the stirring rotator 1a is attracted by the suction force by the jet from the discharge port 14, and the flow from below to the stirring rotator 1a is: It is attracted by the suction force by the suction port 12 and the suction force by the jet flow from the discharge port 14. Accordingly, the flow from the lower side is stronger than the flow from the upper side by the amount of the suction force by the suction port 12. Further, the flow from above and below toward the stirring rotator 1a becomes a swirling flow as the stirring rotator 1a rotates.

  By generating such a circulating flow, a stirring force can be exerted on substantially the entire object to be stirred 100 in the container 30, so that the object to be stirred 100 can be efficiently stirred. In addition, the sediment settled on the bottom 32 of the container 30 is appropriately wound up by a relatively strong swirling flow toward the stirring rotor 1a from below, and dispersed in the stirred object 100 by the jet from the discharge port 14. It becomes possible.

  On the other hand, in the stirring rotator 1 of the present embodiment, as described above, the partition member 18 makes it difficult for the suction force generated by the jet flow from the discharge port 14 to act on the flow from below. It is possible to weaken the swirling flow toward 1 as compared with the rotating body 1a for stirring. In other words, the stirring rotator 1 can balance the swirling flow generated above and below the stirring rotator 1 and appropriately control the flow state in the stirring object 100.

  Thereby, it is possible to prevent the swirling flow generated below (the front end side) of the stirring rotator 1 from becoming too strong. For example, in the case where pebbles, sand, or the like is present at the bottom 32 of the container 30. However, it is possible to prevent such a problem that they rotate with the swirling flow and wear the bottom portion 32 of the container 30. Moreover, since it is not necessary to reduce the rotation speed of the rotating body 1 for stirring, it is possible to weaken only the swirling flow below while maintaining a circulating flow having a necessary strength as appropriate. That is, since the strength of the flow to the suction port 12 and the flow from the discharge port 14 can be ensured, the downward swirling flow can be weakened without reducing the overall stirring force.

  In particular, in this embodiment, since the partition member 18 is configured in a substantially bowl shape so that the partition member 18 does not hinder the jet flow from the discharge port 14, the partition member 18 is provided so that the main body 10 is provided. The stirring force which it has does not fall. Moreover, since the rotational resistance in the to-be-stirred thing 100 can be made small by comprising the partition member 18 in substantially bowl shape, it is possible to suppress the raise in the electric power cost etc. which are required for stirring.

  As a result, appropriate circulation without being limited by the internal conditions of the container 30 or the like containing the object to be stirred 100, the properties of the object to be stirred 100, the state of the contents in the object to be stirred 100, etc. It is possible to generate a flow. That is, efficient stirring can be performed without being affected by the state of the object to be stirred 100.

  The posture of the stirring rotating body 1 in the object to be stirred 100 is not limited to the posture in which the suction port 12 is directed downward as shown in FIG. 3A. For example, the posture in which the suction port 12 is directed upward. It goes without saying that other postures, such as a posture directed to the side or the side, may be used. Further, the thickness T of the partition member 18 shown in FIG. 1B, the protrusion amount P in the centrifugal direction, and the distance D1 between the discharge port 14 and the partition member 18 (first partition surface 18a) in the central axis C direction. Is not particularly limited, and may be appropriately set according to a desired flow state. That is, by adjusting the size and position of the partition member 18, the degree of weakening the swirl flow can be adjusted.

  Next, other forms of the stirring rotor 1 will be described. FIGS. 4A to 4C, FIGS. 5A to 5D, and FIGS. 6A to 6D are diagrams showing examples of other forms of the partition member 18. 4A to 4C are plan views, and FIGS. 5A to 5D and FIGS. 6A to 6D are front views (side views). 5A and 5B show a part of the stirring rotator 1 in cross section.

  The shape of the partition member 18 is not particularly limited, and various shapes can be adopted. For example, as illustrated in FIG. 4A, the partition member 18 may be configured to have a shape in which the protruding amount P in the centrifugal direction changes along the circumferential direction of the main body 10. Further, the partition member 18 is not limited to the one provided over the entire circumference of the main body 10, and is provided partially in the circumferential direction of the main body 10, for example, as shown in FIG. May be. In other words, the plurality of partition members 18 may be arranged in the circumferential direction of the main body 10.

  For example, as shown in FIG. 4C, the partition member 18 may be provided with a plurality of through holes 18c. Furthermore, although illustration is abbreviate | omitted, you may make it comprise the partition member 18 from a mesh-shaped member. Thus, in addition to the setting of the dimension and position of the partition member 18, the flow state around the stirring rotating body 1 can be more finely controlled by appropriately setting the shape of the partition member 18. .

  Further, as shown in FIGS. 5A and 5B, the partition member 18 may have a convex portion 18 d on the first partition surface 18 a or the second partition surface 18 b. Providing the first partition surface 18a with a convex portion 18d having an appropriate configuration makes it possible to appropriately control the vortex generation state between the jet from the discharge port 14 and the first partition surface 18a. In addition, by providing the second partition surface 18b with a convex portion 18d having an appropriate configuration, it is possible to appropriately control the flow state in the vicinity of the bottom surface 10b of the main body 10 and in the vicinity of the second partition surface 18b.

  The convex portions 18d may be provided continuously over the entire circumference of the first partition surface 18a or the second partition surface 18b as shown in FIGS. 5 (a) and 5 (b). , May be provided intermittently. Needless to say, the shape, position, and number of the protrusions 18d are not particularly limited. Moreover, it may replace with the convex part 18d and you may make it provide a recessed part (dent) in the 1st partition surface 18a or the 2nd partition surface 18b.

  Moreover, the partition member 18 may be comprised from the bent member, as FIG.5 (c) shows. In addition, as shown in FIG. 5D, when a plurality of partition members 18 are arranged in the circumferential direction of the main body 10, the positions of the partition members 18 in the central axis C direction may be shifted. . Thus, by appropriately providing the first partition surface 18a and the second partition surface 18b with uneven shapes, steps, inclinations, etc., the flow state around the stirring rotor 1 can be controlled more finely. It becomes possible.

  Further, the partition member 18 is not limited to the second partition surface 18b continuous with the bottom surface 10b of the main body 10, and the second partition surface 18b may not be continuous with the bottom surface 10b. In this case, for example, as shown in FIG. 6 (a), the partition member 18 may be protruded from the intermediate portion of the side surface 10c of the main body 10, or as shown in FIG. 6 (b), the central axis The partition member 18 may be configured to protrude in the centrifugal direction after protruding in the C direction. Thus, in addition to the distance D1 between the discharge port 14 and the first partition surface 18a in the central axis C direction, the distance D2 between the suction port 12 and the second partition surface 18b in the central axis C direction is appropriately set. By setting, the flow state around the stirring rotating body 1 can be controlled more finely.

  Further, as shown in FIG. 6C, the partition member 18 is connected to the main body 10 via, for example, a rod-shaped connection portion 18 e and is provided in a state where a gap G is formed between the partition member 18 and the main body 10. It may be. Thus, by providing the gap G between the main body 10 and the partition member 18, it is possible to control the state of vortex generation between the jet from the discharge port 14 and the first partition surface 18a.

  In this case, as shown in FIG. 6C, the partition member 18 may be provided separately from the main body 10 in the central axis C direction, or separated in the centrifugal direction. It may be provided. Needless to say, the size and shape of the gap G and the shape and number of the connecting portions 18e are not particularly limited.

  Further, the partition member 18 is not limited to the one projecting in a direction substantially parallel to the centrifugal direction, and as shown in FIG. 6D, the main body 10 in a direction (oblique direction) having an angle with respect to the centrifugal direction. It may be provided so as to protrude from. In this manner, by adjusting the protruding direction of the partition member 18, the flow state around the stirring rotating body 1 can be controlled more finely.

  In this case, the partition member 18 may protrude in the centrifugal direction or the central axis C direction after protruding from the main body 10 in an oblique direction, or may protrude from the main body 10 in the centrifugal direction or the central axis C direction. It may protrude later in an oblique direction. 6D shows an example in which the partition member 18 is obliquely projected toward the opposite side of the discharge port 14, but the partition member 18 is obliquely projected toward the discharge port 14 side. Needless to say, it may be allowed to be allowed to.

  In this way, by appropriately setting the shape, size, and position of the partition member 18, the flow state around the stirring rotor 1 is controlled to generate an appropriate circulating flow in the stirring object 100, thereby improving the efficiency. Agitation can be performed. In addition, it is preferable that the partition member 18 is a shape which does not inhibit the jet from the discharge port 14 as mentioned above from a viewpoint of maintaining the whole stirring force with respect to the to-be-stirred object 100. Specifically, the partition member 18 preferably has a shape that does not overlap the discharge port 14 when viewed from the direction of the discharge port 14. Furthermore, it is preferable that the partition member 18 does not have a surface continuous with the inner wall of the flow passage 16 (centrifugal direction portion 16b) connected to the discharge port 14 depending on the property (for example, viscosity) of the object 100 to be stirred. Further, from the viewpoint of reducing the power cost required for stirring, the partition member 18 preferably has a shape that does not increase the rotational resistance in the object to be stirred 100. Specifically, it is preferable that the partition member 18 has a cross-sectional shape and position parallel to the central axis C that are substantially constant along the circumferential direction of the main body 10.

  7A to 7D are diagrams illustrating examples of other forms of the main body 10. 7A to 7C are front views, and FIG. 7D is a cross-sectional view. The shape of the main body 10 is not particularly limited, and various shapes can be adopted. For example, as shown in FIG. 7A, the main body 10 may be configured in a substantially bullet shape combining a substantially hemisphere and a substantially cylindrical shape. By configuring the main body 10 in this way, it becomes possible to more smoothly merge the flow from above (the drive shaft 20 side) with the jet from the discharge port 14.

  Further, as shown in FIG. 7B, the main body 10 has a part of the suction port 12 (two of the four suction ports 12 in this example) provided on the upper surface 10a (the drive shaft 20 side). May be used. Further, as shown in FIG. 7C, the main body 10 has the suction port 12 provided on the bottom surface 10b and the top surface 10a, respectively, and the discharge port 14 is connected to the suction port 12 on the top surface 10a and the suction port 12 on the bottom surface 10b. It may be configured as follows. Thus, by providing the suction port 12 not only on the bottom surface 10b but also on the top surface 10a, the flow state in the stirring object 100 can be controlled more appropriately.

  Further, as shown in FIG. 7D, the main body 10 may be configured such that the shaft portion flow passage 22 provided in the drive shaft 20 and the flow passage 16 are connected. In this case, various gases, liquids, solids, and the like outside the object to be stirred 100 are sucked into the flow path 16 through the shaft flow path 22 and ejected together with the object to be stirred 100 from the discharge port 14. And the like can be mixed, dispersed or dissolved in the object to be stirred 100. In this embodiment, in particular, since the vortex is generated in the vicinity of the discharge port 14 by the partition member 18, it is possible to promote mixing, dispersion, or dissolution of various gases. Further, the bubbles mixed in the object to be stirred 100 can be efficiently converted into microbubbles.

  In addition, although illustration is abbreviate | omitted, the shapes of the main body 10 can employ | adopt other arbitrary shapes, such as spherical shape, hemispherical shape, polygonal column shape, for example. Further, the shape (cross-sectional shape) of the suction port 12 and the discharge port 14 and the cross-sectional shape of the flow passage 16 are not limited to a circular shape, and may be other shapes such as an elliptical shape and a polygonal shape. Good. Further, the direction of the suction port 12 and the discharge port 14 may be a direction (oblique direction) having an angle with respect to the central axis C direction or the centrifugal direction. Further, the flow path 16 may be configured as a curved path that is smoothly curved, or may be configured to linearly connect the suction port 12 and the discharge port 14. .

  Moreover, in this embodiment, although parts other than the flow path 16 of the main body 10 are comprised solid, you may make it comprise parts other than the flow path 16 of the main body 10 hollowly. Moreover, the material which comprises the main body 10 is not specifically limited, For example, appropriate materials according to use conditions, such as a metal, ceramics, resin, rubber | gum, wood, etc., are employable.

It is a bottom view of the rotary body 2 for use. The stirring rotator 2 of the present embodiment is such that the partition member 18 is provided on the opposite side of the suction port 12 with respect to the discharge port 14, and the other configurations are the stirring rotator of the first embodiment. 1 is the same. Therefore, in the following description, the same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted, and only different parts are described.

  As shown in FIGS. 8A to 8C, the partition member 18 of the present embodiment is a substantially bowl-shaped member provided so as to protrude in the centrifugal direction from the upper surface 10a side end portion of the side surface 10c. . The first partition surface 18 a that is the surface of the partition member 18 on the drive shaft 20 side is configured to be substantially parallel to the centrifugal direction and to be continuous with the upper surface 10 a of the main body 10. In addition, the second partition surface 18b, which is the surface on the distal end side of the partition member 18, is a surface on the discharge port 14 side in the present embodiment, and is configured substantially parallel to the centrifugal direction.

  FIG. 9 is a diagram illustrating an example of a usage state of the stirring rotating body 2. As shown in FIG. 9, in this embodiment, a vortex is generated between the partition member 18 positioned above the discharge port 14 and the jet flow from the discharge port 14. It is difficult for the suction force by the jet flow to act on the flow from above. Therefore, the swirl flow from above to the stirring rotator 2 is extremely weak because the suction port 12 is not provided on the upper surface 10a, and as a result, a weak flow circulation above the stirring rotator 2 is obtained. A flow will be generated.

  On the other hand, below the stirring rotator 2, the flow of the circulating flow is promoted as the upper circulating flow becomes weaker. As a result, the swirl flow from below to the stirring rotator 2 becomes stronger, and the flow spreading radially from the stirring rotator 2 is drawn downward at a relatively early stage by this strong swirl flow. . That is, in the present embodiment, a strong circulating flow is positively generated below the stirring rotator 2, that is, on the tip side, and the range in which the strong circulating flow is generated is narrowed in the centrifugal direction.

  Therefore, according to the stirring rotator 2 of the present embodiment, it is possible to apply a stronger stirring force substantially intensively to a specific region below the stirring rotator 2. Thereby, for example, the emulsification of the object to be stirred 100 and the dispersion of the sediment deposited on the bottom 32 of the container 30 can be performed quickly and efficiently. In addition, by adjusting the size, shape, and position of the partition member 18, it is possible to adjust the range of the region where a stronger stirring force is exerted and the strength of the stirring force in this region. A fluid state corresponding to the properties and the like is generated in the object to be stirred 100 so that efficient stirring can be performed.

  Needless to say, other forms of the partition member 18 and the main body 10 described in the first embodiment can also be applied to this embodiment. Further, as in the first embodiment, the posture of the stirring rotating body 2 in the stirring target 100 is not particularly limited.

<Third Embodiment>
Next, the stirring rotator 3 according to the third embodiment of the present invention will be described. 10A is a plan view of the stirring rotator 3, FIG. 10B is a front view of the stirring rotator 3, and the side view is the same, and FIG. 10C is a stirrer. It is a bottom view of the rotary body 3 for use. The stirring rotator 3 of the present embodiment is such that the partition member 18 is provided on both the suction port 12 side and the opposite side with respect to the discharge port 14, and the other configuration is the first or second configuration. It is the same as the rotating body for stirring 1 or 2 of the embodiment. Accordingly, in the following description, the same parts as those in the first or second embodiment are denoted by the same reference numerals and the description thereof is omitted, and only different parts will be described.

  As shown in FIGS. 10A to 10C, in the present embodiment, the partition member 18 is provided on both the bottom surface 10b side end portion and the top surface 10a side end portion of the side surface 10c. In the present embodiment, the two partition members 18 are configured in substantially the same shape, and the partition member 18 on the bottom surface 10b side is configured such that the second partition surface 18b is continuous with the bottom surface 10b, and the top surface 10a. The side partition member 18 is configured such that the first partition surface 18a is continuous with the upper surface 10a.

  FIG. 11 is a diagram illustrating an example of a usage state of the rotating body 3 for stirring. As shown in FIG. 11, in this embodiment, vortices are respectively generated between the jet flow from the discharge port 14 and the upper and lower partition members 18, whereby the suction force by the jet flow from the discharge port 14 is It is difficult to act on both the flow from above and the flow from below.

  Therefore, the swirl flow from the lower part toward the stirring rotator 3 and the swirl flow from the upper part toward the agitation rotator 3 are both weak, and as a result, the flow radially spreading from the agitation rotator 2 is further distant. It becomes possible to reach. That is, in this embodiment, by making it less susceptible to the swirling flow up and down of the stirring rotator 3, the straightness of the flow spreading radially from the stirring rotator 2 can be improved, and it is possible to reach farther away. It is said.

  Therefore, according to the stirring rotator 3 of the present embodiment, it is possible to exert a stirring force over a wider range in the centrifugal direction. Thereby, even when the width direction dimension of the container 30 is large, for example, the stirring force can be exerted on substantially the entire object to be stirred 100, so that efficient stirring can be performed. In addition, while exerting a stirring force on substantially the entire object to be stirred 100, it is possible to prevent the vertical swirling flow of the stirring rotating body 3 from becoming too strong. For example, the bottom 32 of the container 30 is strongly worn. It is possible to prevent problems caused by the swirling flow.

  In addition, by adjusting the size, shape and position of the two partition members 18, it is possible to adjust the reach of the flow spreading radially and the strength of the upper and lower swirl flows, so that it corresponds to the shape of the container 30. It is possible to generate a fluid state in the object to be stirred 100 and perform efficient stirring. Furthermore, the balance of the upper and lower swirling flows can be adjusted by appropriately changing the size, shape, and position of the two partition members 18.

  Needless to say, other forms of the partition member 18 and the main body 10 described in the first embodiment can also be applied to this embodiment. Further, as in the first embodiment, the posture of the stirring rotating body 3 in the stirring target 100 is not particularly limited.

<Fourth Embodiment>
Next, the stirring rotator 4 according to the fourth embodiment of the present invention will be described. 12 (a) is a plan view of the stirring rotator 4, FIG. 12 (b) is a front view of the stirring rotator 4 (the same side view), and FIG. 12 (c) is a stirrer. It is a bottom view of the rotating body 4 for use. The stirring rotator 4 of this embodiment is obtained by adding an adjusting member 19 to the stirring rotators 1 to 3 of the first to third embodiments, and other configurations are the first to third embodiments. Are the same as the rotating bodies 1 to 3 for stirring. Therefore, in the following description, the same parts as those in the first to third embodiments are denoted by the same reference numerals, the description thereof is omitted, and only different parts will be described.

  In the example shown in FIGS. 12A to 12C, the partition member 18 is provided at the end of the side surface 10 c on the bottom surface 10 b side in the same manner as the stirring rotator 1 of the first embodiment. The surface 18b is configured to be continuous with the bottom surface 10b. The adjustment member 19 is a substantially quadrangular columnar member that protrudes toward the discharge port 14 from the outer peripheral end of the first partition surface 18a that is the surface of the partition member 18 on the discharge port 14 side. A plurality are arranged along the circumferential direction. In other words, the adjustment member 19 is provided intermittently in the circumferential direction of the main body 10.

  Thus, by providing the adjustment member 19 intermittently, the flow around the stirring rotor 4 can be appropriately disturbed, so that the flow and vortex generation around the discharge port 14 can be more appropriate. It becomes possible. Further, by adjusting the protruding amount Pa of the adjusting member 19 from the partition member 18 and the interval S between the adjusting members 19, the flow state around the stirring rotor 4 is adjusted more finely, and a desired flow state is generated. can do.

  Further, as shown in FIG. 12B, the adjustment member 19 partially overlaps the discharge port 14 when viewed from the direction of the discharge port 14, thereby allowing the jet flow from the discharge port 14 to flow. It can be appropriately disturbed without changing the direction. Thereby, for example, various gases, liquids or solids mixed in the object to be stirred 100 through the shaft flow passage 22 (see FIG. 7D) of the drive shaft 20 while maintaining the overall stirring force. It becomes possible to further improve the efficiency of mixing, dispersion or dissolution, and to further increase the ability to generate microbubbles.

  FIGS. 13A to 13C, 14 </ b> A to 14 </ b> C, and 15 </ b> A to 15 </ b> C are diagrams illustrating examples of other forms of the stirring rotor 4. FIGS. 13A and 13B, FIGS. 14A and 14B, and FIGS. 15A to 15C are front views (side views), and FIGS. (C) is a plan view.

  The shape of the adjustment member 19 is not particularly limited, and various shapes can be employed. For example, as shown in FIG. 13A, the adjustment member 19 may be configured in a substantially triangular flat plate shape. Although not illustrated, the adjustment member 19 may be other shapes such as a columnar shape or a conical shape. It may be configured in a shape. Further, the adjusting member 19 is not limited to the one protruding in the direction parallel to the central axis C direction, and may be one protruding in a direction having an angle with respect to the central axis C (an oblique direction).

  For example, as shown in FIG. 13B, the size, shape, or interval of the adjustment member 19 may be changed according to the circumferential position of the main body 10. In this case, although not shown, the adjustment member 19 and the discharge port 14 may not completely overlap when viewed from the direction of the discharge port 14. That is, the adjustment member 19 may partially overlap the discharge port 14 when viewed from the direction of the discharge port 14 or may not completely overlap. Moreover, the position of the adjustment member 19 with respect to the main body 10 and the partition member 18 is not specifically limited, It can provide in arbitrary positions. Further, for example, as shown in FIG. 13C, the adjustment members 19 may be arranged in a plurality of rows.

  Moreover, the adjustment member 19 may be configured in a mesh shape, for example, as shown in FIG. 14 (a) or (b). In this case, the same effect as that obtained when the adjustment member 19 that is not mesh-shaped is provided intermittently in the circumferential direction of the main body 10 can be obtained. In this case, as shown in FIG. 14 (a) or (b), the mesh-shaped adjusting member 19 may be provided continuously in the circumferential direction of the main body 10, and the illustration is omitted. The mesh-shaped adjusting member 19 may be provided intermittently in the circumferential direction of the main body 10. Further, the mesh-shaped adjusting members 19 may be arranged in a plurality of rows or layers, or the mesh-shaped adjusting members 19 and the non-mesh adjusting members 19 may be combined.

  Even when the adjustment member 19 is provided, the configuration of the partition member 18 is not particularly limited, and various configurations as described in the first embodiment can be employed. For example, as shown in FIG. 14C, a plurality of partition members 18 may be arranged along the circumferential direction of the main body 10, and an adjustment member 19 may be provided for each partition member 18.

  Further, the partition member 18 may be provided on the opposite side of the suction port 12 with respect to the discharge port 14, for example, as shown in FIG. As shown in c), it may be provided on both the suction port 12 side and the opposite side with respect to the discharge port 14. That is, the adjusting member 19 may be provided on the stirring rotator 2 of the second embodiment or the stirring rotator 3 of the third embodiment.

  When the adjusting member 19 is provided on the stirring rotor 3, the adjusting member 19 is provided so as to connect the partition members 18 on both sides of the discharge port 14 as shown in FIG. 15B, for example. Alternatively, for example, as shown in FIG. 15C, it may be provided independently for each partition member 18 on both sides of the discharge port 14.

<Fifth Embodiment>
Next, a stirring device 5 according to a fifth embodiment of the present invention will be described. The stirring device 5 of the present embodiment is obtained by connecting a plurality of stirring rotors 1 to 4 of the first to fourth embodiments in the central axis C direction. FIG. 16 is a front view (side view) of the stirring device 5 and shows an example in which three stirring rotating bodies 1 to 3 are connected via the drive shaft 20.

  Thus, it is possible to further improve the stirring efficiency by connecting the plurality of rotating bodies for stirring 1 to 4 in the direction of the rotation axis. In particular, the depth of the container 30 that accommodates the object to be stirred 100 is increased. It is effective when it is deep. In addition, the stirring apparatus 5 may be one in which a plurality of the same configuration among the rotating bodies 1 to 4 for stirring are connected, or a plurality in which different configurations are connected. That is, for example, the stirring efficiency can be further improved by selecting and disposing the stirring rotors 1 to 4 having an appropriate configuration according to the position in the central axis C direction such as the depth of the container 30. . Moreover, it cannot be overemphasized that the number of the rotation bodies 1-4 for stirring connected is not limited.

  As described above, the stirring rotating bodies 1 to 4 according to the first to fourth embodiments are the main body 10 that rotates about the rotation axis (center axis C) and the suction provided on the surface of the main body 10.

  With such a configuration, the rotation for stirring is performed by the flow from the suction port 12 side (front end side) or the opposite side (drive shaft 20 side) toward the stirring rotating bodies 1 to 4 and the jet flow from the discharge port 14. Since the flow spreading radially from the bodies 1 to 4 can be appropriately separated, the flow state in the stirring object 100 can be controlled to a desired flow state. Thereby, it becomes possible to perform efficient stirring irrespective of the state of the object 100 to be stirred.

  The partition member 18 is preferably configured in a shape that does not overlap the discharge port 14 when viewed from the direction of the discharge port 14. By doing so, it is possible to prevent the jet flow from the discharge port 14 from being obstructed, so that an appropriate flow in the stirred object 100 is maintained while maintaining the overall stirring force for the stirred object 100. A state can be generated.

  In the stirring rotor 1, the partition member 18 is provided between the discharge port 14 and the suction port 12. By doing so, it is possible to appropriately weaken the flow from the suction port 12 side (front end side) toward the stirring rotor 1 and to control the flow state in the stirring object 100 to a desired flow state.

  Further, in the stirring rotor 2, the partition member 18 is provided on the opposite side of the suction port 12 with respect to the discharge port 14. By doing so, the flow from the side opposite to the suction port 12 (drive shaft 20 side) toward the stirring rotator 2 is appropriately weakened, and the flow state in the stirring object 100 is controlled to a desired flow state. Can do.

  Moreover, in the rotating body 3 for stirring, the partition member 18 is provided on both sides in the direction of the rotation axis (center axis C) with respect to the discharge port 14. By doing so, the flow from the suction port 12 side (front end side) and the opposite side (drive shaft 20 side) toward the stirring rotors 1 to 4 is appropriately weakened, and the flow state in the stirring object 100 is changed. The desired flow state can be controlled.

  Further, the partition member 18 may be provided continuously in the circumferential direction of the main body 10. In this way, the stirring rotator 1 is caused by the flow from the suction port 12 side (front end side) or the opposite side (drive shaft 20 side) toward the stirring rotators 1 to 4 and the jet from the discharge port 14. It is possible to more effectively isolate the flow spreading radially from ˜4.

  Further, the partition member 18 may be configured in a shape in which the shape and position of a cross section parallel to the rotation axis (center axis C) are substantially constant along the circumferential direction of the main body 10. By doing in this way, the flow state in the to-be-stirred object 100 can be controlled to a desired flow state, without increasing the rotational resistance of the rotating bodies 1 to 4 for stirring.

  The stirring rotor 4 includes an adjustment member 19 that protrudes from the partition member 18 toward the discharge port 14, and the adjustment member 19 is provided intermittently in the circumferential direction of the main body 10, or the partition member It is comprised in the mesh shape which protrudes toward the discharge outlet 14 side from 18. FIG. In this way, the flow around the stirring rotator 4 can be appropriately disturbed, so that the flow state around the stirring rotator 4 can be finely adjusted to generate a desired flow state. can do. In addition, various gases, liquids, solids, and the like mixed in the object to be stirred 100 can be mixed, dispersed and dissolved, and microbubbles can be generated more efficiently.

  Further, the stirring device 5 according to the fifth embodiment is configured by arranging a plurality of stirring rotating bodies 1 to 4 in the direction of the rotation axis (center axis C). By setting it as such a structure, the rotary bodies 1-4 for stirring can be arrange | positioned combining suitably, and more efficient stirring can be performed.
