- FIG. 1 (a) is a plan view of the stirring rotator 1
- FIG. 1 (b) is a front view of the stirring rotator 1 (the same side view).
- the stirring rotator 1 includes a substantially hemispherical main body 10, a plurality of suction ports 12 provided on the surface of the main body 10, and a plurality of discharges provided on the surface of the main body 10.
- the outlet 14 is composed of a flow passage 16 formed in the main body 10 so as to connect the suction port 12 and the discharge port 14.
- the main body 10 has a substantially hemispherical shape, specifically, a shape in which one bottom surface 10b of the disk is formed into a spherical shape.
- a connecting portion 18 to which a driving shaft 20 of a driving device such as a motor is connected is provided at the center of the other bottom surface 10a of the main body 10. Therefore, the stirring rotating body 1 is configured to rotate about the central axis C of the main body 10 as a rotation axis.
- the connection method of the drive shaft 20 and the connection part 18 may be any known method such as a screw or engagement.
- the strength of the main body 10 is increased by configuring the main body 10 with a solid portion other than the flow passage 16.
- the material which comprises the main body 10 is not specifically limited, For example, a suitable material according to use conditions, such as a metal, ceramics, resin, rubber
- the suction port 12 is provided on the bottom surface 10 b of the main body 10 on the side opposite to the connection portion 18.
- the four suction ports 12 are arranged at equal intervals on a circumference centered on the central axis C, and are formed in the same direction as the central axis C.
- the discharge port 14 is provided on the side surface 10 c of the main body 10.
- the four discharge ports 14 are positioned at positions outside the main body 10 in the radial direction (centrifugal direction) with respect to the respective suction ports 12 (positions separated from the central axis C in a direction perpendicular to the central axis C). Each is arranged. Further, the discharge port 14 is formed in a direction orthogonal to the central axis C.
- the flow passage 16 is formed as a passage connecting one suction port 12 and one discharge port 14. Accordingly, four flow passages 16 are formed inside the main body 10. Each flow passage 16 is formed so as to straightly advance from the suction port 12 along the direction of the central axis C, then bend at a right angle, and straight forward toward the radially outer side of the main body 10 to reach the discharge port 14.
- the flow passage 16 is configured in this manner, so that the suction port 12, the discharge port 14, and the flow passage 16 can be easily formed by drilling with a drill.
- the suction port 12, the discharge port 14, and the flow passage 16 can be easily formed by drilling a hole from the position of the suction port 12 in the direction of the central axis C and drilling a hole from the position of the discharge port 14 toward the central axis C. Can be formed.
- the cross-sectional shape of the flow path 16 is comprised circularly, it is not limited to this, For example, it is good also as other cross-sectional shapes, such as an ellipse and a polygon.
- FIG. 2A is a plan view showing the operation of the stirring rotator 1
- FIG. 2B is a front view showing the operation of the stirring rotator 1.
- the stirring rotating body 1 is driven by the drive shaft 20 and rotates about the central axis C in the object to be stirred that is a fluid, thereby stirring the object to be stirred.
- the stirring rotator 1 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 as shown in these drawings, the fluid in the flow passage 16 flows toward the radially outer side of the stirring rotating body 1. Since the discharge port 14 is provided on the radially outer side of the main body 10 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 is rotating.
- 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.
- a flow that radiates from the side surface 10 c where the discharge port 14 is provided and a flow toward the tip of the stirring rotator 1 that includes the suction port 12 are generated. .
- the stirring rotator 1 when the stirring rotator 1 is immersed in the fluid and rotated, the fluid in the vicinity of the surface of the stirring rotator 1 rotates together with the stirring rotator 1 due to the influence of viscosity. Accordingly, the centrifugal force also acts on the fluid near the surface of the stirring rotator 1, and as shown in these drawings, the fluid near the surface flows along the surface of the stirring rotator 1 to the side surface 10c and discharges it. It becomes an accompanying flow of the jet from the outlet 14.
- the shape of the main body 10 since the bottom surface 10b is formed in a spherical shape, the shape of the main body 10 has a shape in which the axial thickness gradually decreases outward in the radial direction. It is possible to smoothly merge the flow into the flow spreading radially from the side surface 10c. Further, by forming the bottom surface 10b in such a shape, a part of the flow toward the tip of the stirring rotator 1 smoothly flows to the side surface 10c along the bottom surface 10b, and the flow spreads radially from the side surface 10c. It is possible to join. As a result, the rotating body for stirring 1 can generate a powerful flow in the surrounding fluid, so that efficient stirring can be performed.
- FIGS. 3 (a) and 3 (b) and FIGS. 4 (a) and 4 (b) are schematic views showing an example of use of the stirring rotator 1.
- the stirring rotator 1 is connected to the drive shaft 20 of a drive device 30 such as a motor, and is immersed in an object to be stirred 50 that is a fluid contained in a container 40. Used in.
- the driving device 30 may be fixed to the container 40, a pedestal, or the like, or may be held and operated by a user.
- the stirring rotator 1 By rotating the stirring rotator 1 by the driving device 30, a flow that radially spreads from the stirring rotator 1 and a flow toward the tip of the stirring rotator 1 are generated as described above. As a result, as shown in FIGS. 3A and 3B, a complicated circulation flow is generated in the stirring object 50, and the stirring object 50 is sufficiently stirred by this circulation flow.
- the cross section perpendicular to the rotation axis direction of the main body 10 is formed in a circular shape so that there is no portion that collides with the agitated object 50 during the rotation. Almost never occurs.
- the tip of the rotating body for stirring 1 may be brought close to the bottom of the container 40 as shown in FIG. By doing so, the staying material can be sucked up from the suction port 12 and ejected from the discharge port 14, and the staying material can be sufficiently dispersed in the stirring object 50.
- the tip of the stirring rotor 1 may be brought close to the corner of the container 40 as shown in FIG. .
- the suction port 12 can be sufficiently brought close to a narrow corner portion.
- the cross section perpendicular to the rotation axis direction of the main body 10 is formed in a circular shape and has no protrusions, so that the stirring rotor 1 is stirred even when it hits the wall surface of the container 40.
- the possibility that the rotating body 1 or the container 40 is damaged or scraped is reduced.
- the rotating body 1 for stirring can be brought close to the wall surface of the container 40 with peace of mind, and it is possible to sufficiently stir all the corners of the container 40.
- fragments or shavings etc. of the rotating body for stirring 1 or the container 40 are not easily mixed into the object to be stirred 50.
- the suction port 12 is arranged slightly outside the center of the tip of the stirring rotator 1 (center axis C, which is the rotation axis), so that the tip of the stirring rotator 1 is placed on the wall surface of the container 40. Even when they are brought into contact with each other, the suction port 12 is prevented from being blocked. For this reason, the rotating body 1 for stirring can be stably operated even near the wall surface of the container 40.
- FIG. 2A shows an example in which the flow passage 16 is configured as a smoothly curved passage.
- FIG. 5B shows an example in which the flow passage 16 is configured in a straight line. Even when the flow passage 16 is configured in this manner, the flow resistance in the flow passage 16 can be reduced. Furthermore, in this case, it is possible to facilitate cleaning of the flow passage 16.

- FIG. 43 (a) is a plan view showing the operation of the stirring rotator 500
- FIG. 43 (b) is a front view showing the operation of the stirring rotator 500.
- the stirring rotator 500 is driven by the drive shaft 20 and rotates about the central axis C in the object to be stirred that is a fluid, thereby stirring the object to be stirred.
- the stirring rotator 500 When the stirring rotator 500 is immersed in the fluid and rotated, the fluid that has entered the flow passage 516 also rotates together with the stirring rotator 500. Then, centrifugal force acts on the fluid in the flow passage 516, and the fluid in the flow passage 516 flows toward the outside in the radial direction of the agitating rotator 500 as shown in these drawings. Since the discharge port 514 is provided on the outer side of the main body 510 in the centrifugal direction than the suction port 512, a stronger centrifugal force acts on the discharge port 514 than on the suction port 512. Accordingly, the fluid flows from the suction port 512 toward the discharge port 514 as long as the stirring rotator 500 rotates.
- the stirring rotator 500 when the stirring rotator 500 is immersed in the fluid and rotated, the fluid in the vicinity of the surface of the stirring rotator 500 rotates with the stirring rotator 500 due to the influence of viscosity. Accordingly, the centrifugal force also acts on the fluid near the surface of the stirring rotator 500, and as shown in these drawings, the fluid near the surface flows along the surface of the stirring rotator 500 to the vicinity of the discharge port 514. Then, it becomes an accompanying flow of the jet from the discharge port 514.
- the flow in the vicinity of the tip of the stirring rotator 500 can be smoothly merged with the flow that spreads radially from the side surface. Further, by forming the main body 510 in such a shape, a part of the flow toward the tip of the stirring rotator 500 is smoothly flowed to the vicinity of the discharge port 514 along the inclined surface 510b, and from the side surface portion. It is possible to join the flow spreading radially. As a result, since the stirring rotator 500 can generate a strong flow in the surrounding fluid, efficient stirring can be performed.
- the discharge port 514 when the discharge port 514 is disposed on a plane parallel to the rotation axis (center axis C), the gas in the flow passage 516 (before being immersed in the fluid) is obtained when trying to stir the highly viscous fluid.
- the air or the like existing in the flow passage 516 cannot be discharged well, and the fluid cannot be ejected from the discharge port 514.
- the inventor of the present application has conducted extensive research and experiments on this phenomenon, and as a result, the discharge port 514 is not a plane parallel to the rotation axis (center axis C) but an inclined surface 510b that is a plane inclined with respect to the rotation axis. It has been found that the gas in the flow passage 516 can be immediately discharged even when the fluid is a highly viscous fluid.
- the discharge port 514 by disposing the discharge port 514 on the inclined surface 510b, the distance from the rotation axis is made different between the tip end side (opposite the connection portion 518) and the drive shaft side (connection portion 518 side) of the discharge port 514, A difference can be made in the peripheral speed and the acting centrifugal force between the front end side of the discharge port 514 and the drive shaft side. Then, a turbulent flow is generated in the flow passage 516 near the discharge port 514 due to the difference between the peripheral speed and the centrifugal force at the discharge port 514, and the gas staying in the flow passage 516 is disturbed, so that the discharge port 514 can quickly Can be discharged.
- the discharge port 514 on the inclined surface 510b, the flow along the inclined surface 510b is separated from the inclined surface 510b, and the discharge port 514 is brought closer to the separation point 510c where the flow in the centrifugal direction becomes a flow (or the separation point). 510c can be in the discharge port 514).
- a negative pressure is generated along with the flow peeling from the inclined surface 510b. Therefore, the gas accumulated in the flow passage 516 due to this negative pressure by bringing the discharge port 514 closer to the peeling point 510c. Can be sucked out from the discharge port 514.
- the discharge port 514 is provided on the inclined surface 510b that gradually moves away from the rotation axis from one to the other in the direction of the rotation axis (center axis C).
- the gas is immediately discharged from the flow passage 516 as soon as the stirring is started, so that the stirring can be performed quickly and efficiently. Further, even when the gas enters the flow passage 516 due to some factor during the stirring, since the entered gas can be immediately discharged from the flow passage 516, the stirring force can be stably exhibited. It is possible.
- the flow that spreads radially from the stirring rotary member 500 is more complicated (turbulent flow) due to the synergistic effect of the difference between the peripheral speed and centrifugal force at the discharge port 514 and the negative pressure at the separation point 510c. Therefore, it is possible to obtain an agitation force that is higher than that of the prior art.
