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.

  Conventionally, for example, when two or more kinds of fluids are mixed or various powders added to the fluid are uniformly dispersed, a stirrer that rotates an impeller in the fluid is used. This impeller is generally provided with a propeller blade and a turbine blade, and agitation is performed by flowing a fluid by rotating.

  Such a stirrer is often used by being permanently installed in a tank containing a fluid, but in addition to this, for example, a handy type for stirring a paint etc. on the spot immediately before use is often used. It is used. This handy type agitator is generally configured by providing an impeller at the tip of a drive shaft of a hand drill type drive device. Then, the user holds the drive device in both hands, inserts the impeller at the tip into a container in which an object to be stirred such as a paint is stored, rotates it, and performs stirring.

  However, this handy type stirrer is very dangerous because an impeller having a sharp blade tip is rotated at a high speed, and there is a problem that it requires careful handling. Also, if an impeller with many protrusions hits the container, or if the impeller causes fatigue failure, the tip of the impeller or part of the container is missing or scraped and mixed into the object to be stirred. There was a problem that it was easy to do.

  Also, since the impeller causes the material to be stirred to flow by colliding with the material to be stirred, in a stirrer equipped with an impeller, when the rotating impeller is put into the material to be stirred, or in the material to be stirred, the impeller When starting to rotate, there was a problem that the impeller was easily shaken by the reaction. For this reason, when the user is not operating the stirrer, situations such as hitting the impeller against the container or scattering the object to be stirred out of the container frequently occurred.

  In addition, in the impeller, when the agitated material contains sediment, the sediment cannot be dispersed well unless stirring is performed while the impeller is in contact with the bottom wall of the container. There has been a problem that debris and scraps generated by contact with the wall surface of the container are likely to be mixed into the object to be stirred.

  On the other hand, instead of using propeller blades and turbine blades, a mixer for a high-viscosity fluid in which an impeller is configured from a hexagonal cylindrical body and a plurality of holes are provided on a side surface has been proposed (for example, , See Patent Document 1).

JP-A-5-154368

  However, in the high-viscosity fluid mixer described in Patent Document 1, the outer shape of the impeller is a hexagonal column, and the object to be stirred is made to flow mainly by causing the outer wall of the impeller to collide with the object to be stirred. The above-described problem of recoil at the start of rotation has not been solved.

  In addition, although the agitated material is allowed to flow out from the side holes, the volume inside the impeller is large relative to the side holes, so the flow rate inside the impeller is low, and the stagnant material will remain when used for a long time. There was a problem that the stirring ability was liable to deteriorate due to adhesion and deposition on the inside of the impeller.

  This invention is made | formed in view of such a situation, Comprising: It aims at providing the rotary body for stirring and stirring apparatus which can perform safe and efficient stirring irrespective of a use.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  First, the structure of the stirring rotating body 1 according to the present embodiment will be described. FIG. 1A is a plan view showing an example of the stirring rotator 1, and FIG. 1B is a front view showing an example of the stirring rotator 1 (the side view is the same). FIG. 3C is a bottom view showing an example of the rotating body 1 for stirring. In FIGS. 2A and 2B, a part is shown in cross section.

  As shown in these drawings, the stirring rotating body 1 includes a substantially shell-shaped 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 inside the main body 10 so as to connect the suction port 12 and the discharge port 14, and a collision member 17 disposed in the suction port 12 and the discharge port 14.

  In this example, the main body 10 has a substantially bullet shape, specifically, a shape in which one bottom surface 10b of the cylinder is formed into a spherical shape, in other words, a shape in which a cylinder and a hemisphere are combined. At the center of the other bottom surface 10a of the main body 10, a connecting portion 18 to which a driving shaft 20 of 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, the connection method of the drive shaft 20 and the connection part 18 may be any known method such as a screw or engagement.

  In this embodiment, the strength of the main body 10 is increased by configuring the main body 10 other than the flow passage 16 to be solid. 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 | gum, wood, etc., is employable. Since the main body 10 of the present embodiment is simple and easy to process, the main body 10 can be configured from a wide variety of materials without being limited by the manufacturing method.

  Further, since the main body 10 is configured in such a simple shape, the occurrence of unbalance with respect to the rotating shaft can be reduced. For this reason, in the present embodiment, unlike an impeller or the like that tends to cause unbalance, it is possible to substantially eliminate vibrations and whirling during rotation.

  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 (that is, the front end portion of the main body 10). In the present embodiment, 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. In the present embodiment, 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. In the present embodiment, the shapes (cross-sectional shapes) of the suction port 12 and the discharge port 14 are circular, but the shapes of the suction port 12 and the discharge port 14 are not particularly limited, and other shapes are possible. It may be.

  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 be straight from the suction port 12 along the direction of the central axis C, then bend at a right angle, and straight forward in the centrifugal direction of the main body 10 to reach the discharge port 14. That is, the flow path 16 of this embodiment is comprised from the axial direction part 16a of the central axis C direction, and the centrifugal direction part 16b of the centrifugal direction.

  In the present embodiment, 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 or the like. Specifically, 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 passage 16 is not particularly limited, and can be configured in an appropriate shape according to the shape and position of the suction port 12 and the discharge port 14 or the processing method. In the present embodiment, the flow passage 16 is formed in an L shape that bends at a substantially right angle for ease of processing. However, the present invention is not limited to this, and the curved passage is smoothly curved. The flow path 16 may be configured, or the flow path 16 may be configured to connect the suction port 12 and the discharge port 14 in a straight line. By configuring the flow passage 16 in this way, the flow resistance in the flow passage 16 can be reduced, so that the flow caused by the stirring rotor 1 can be further strengthened and the stirring ability can be improved.

  The collision member 17 is a substantially rod-shaped member, and is provided in each of the suction port 12 and the discharge port 14. The collision member 17 is a member formed so as to collide with an object to be stirred that passes through the suction port 12 or the discharge port 14, and will be described later in detail, but improves the stirring ability by colliding with the object to be stirred. Is.

  In the present embodiment, the collision member 17 is provided so as to cross the inside of the suction port 12 or the discharge port 14 in a direction orthogonal to the rotation direction of the main body 10. In other words, the collision member 17 provided in the suction port 12 is provided so as to cross the inside of the suction port 12 in the centrifugal direction of the central axis C that is the rotation axis. Further, the collision member 17 provided at the discharge port 14 is provided so as to cross the inside of the discharge port 14 in a direction parallel to the central axis C.

  In the present embodiment, the collision member 17 is provided in both the suction port 12 and the discharge port 14. However, the collision member 17 may be provided only in either the suction port 12 or the discharge port 14. Needless to say. Further, the collision member 17 may be provided only in a part of the plurality of suction ports 12 or only in a part of the plurality of discharge ports 14.

  Next, the operation of the stirring rotating body 1 will be described. FIG. 2A is a plan view showing the operation of the stirring rotator 1, and 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.

  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 rotating body 1 as shown in these drawings. 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 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. Thereby, in the fluid around the stirring rotator 1, 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. Become. The flow toward the tip of the stirring rotator 1 becomes a swirling flow by the rotation of the suction port 12.

  Further, when the stirring rotator 1 is immersed in the fluid and rotated, the fluid near 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.

  In the present embodiment, since the bottom surface 10b is formed in a spherical shape, the shape of the main body 10 has a shape in which the thickness in the direction of the central axis C gradually decreases outward in the radial direction. The nearby flow can be smoothly merged with 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 stirring rotator 1 can generate a powerful flow in the surrounding fluid and perform efficient stirring.

  Furthermore, in the present embodiment, by providing the collision member 17, it is possible to further improve the stirring ability by causing the fluid (agitated object) passing through the suction port 12 and the discharge port 14 to collide with the collision member 17. It is said. FIGS. 3A and 3B and FIGS. 4A and 4B are enlarged cross-sectional views of the suction port 12, the discharge port 14, and the flow passage 16.

  As shown in FIG. 3A, in this embodiment, by providing a collision member 17 at the discharge port 14, the fluid passing through the discharge port 14 from the centrifugal direction portion 16 b of the flow passage 16 collides with the collision member 17. The flow is divided into two parts. By doing in this way, a change can be made to the jet flow from the discharge outlet 14, and it can be set as a complicated flow. Furthermore, when powder or the like is dissolved in the fluid, the powder or the like that has not been melted can be crushed by colliding with the collision member 17, so that the powder or the like is uniformly dissolved in the fluid. It becomes possible to make it.

  Further, by providing the collision member 17 so as to cross in the direction orthogonal to the rotation direction of the main body 10, the collision member 17 can collide with the fluid passing through the discharge port 14 from the lateral direction. Therefore, the jet flow from the discharge port 14 can be made a more complicated flow. The collision from the lateral direction becomes more effective as the rotation speed is increased.

  Although illustration is omitted, the same effect can be obtained by the collision member 17 provided at the suction port 12. In the present embodiment, the agitated material is appropriately collided with the collision member 17 at the suction port 12 and the discharge port 14 as described above, so that the agitation ability is improved and the agitation can be performed more efficiently.

  And in this embodiment, while having the stirring effect by a collision in this way, the trouble which the conventional impeller etc. had was eliminated. In other words, the collision member 17 that collides with the object to be stirred is arranged inside the suction port 12 or the discharge port 14 so as not to protrude outside the main body 10, so that not only safety is high, but also at the start of rotation. No chipping or scraping occurs when it comes into contact with a container or the like.

  The cross-sectional shape of the collision member 17 is not limited to the circular shape shown in FIG. 3A, and may be other shapes such as an elliptical shape and a polygonal shape. Further, as shown in FIG. 3B, for example, the collision member 17 may be provided with a blade portion 17a having a cross-sectional shape in a wedge shape and a sharp tip formed. In this way, by providing the blade portion 17a on the upstream side, the ability to crush a lump such as powder can be increased.

  Further, as shown in FIGS. 4A and 4B, the collision member 17 may be configured in a flat plate shape. In this case, as shown in FIG. 4A, the normal direction N of the surface of the collision member 17 is orthogonal to the flow direction of the fluid (agitated object) passing through the suction port 12 or the discharge port 14. It is possible to increase the crushing ability of a lump such as powder while reducing the resistance to fluid. Furthermore, it is more effective if the blade member 17a is provided at the end in the width direction on the upstream side in the collision member 17 configured in a flat plate shape.

  Further, as shown in FIG. 5B, the normal direction N of the surface of the collision member 17 is arranged in parallel with the flow direction of the fluid (agitated object) passing through the suction port 12 or the discharge port 14. By doing so, the division | segmentation capability by the collision of the horizontal direction with respect to a fluid can be improved. Also in this case, it is more effective if the blade portion 17a is provided at the end in the width direction of the collision member 17 configured in a flat plate shape. Furthermore, by providing the blade portions 17a at both ends in the width direction, the effect can be exhibited regardless of the rotation direction.

  In the present embodiment, the flow passage 16 is formed in an L-shape that is bent at a substantially right angle for ease of processing. However, the present invention is not limited to this, and a smoothly curved curved passage is used. The flow path 16 may be configured, or the flow path 16 may be configured to connect the suction port 12 and the discharge port 14 in a straight line. By configuring the flow passage 16 in this way, the flow resistance in the flow passage 16 can be reduced, so that the flow caused by the stirring rotor 1 can be further strengthened and the stirring ability can be improved.

  Further, the discharge port 14 is arranged so as to be shifted in the rotational direction with respect to the suction port 12, and a portion connected to the discharge port 14 of the flow passage 16 is configured to have an angle with respect to the centrifugal direction of the stirring rotating body 1. Also good. Alternatively, the discharge port 14 may be arranged so as to be shifted in the direction of the rotation axis, and the portion connected to the discharge port 14 of the flow passage 16 may be configured to face the distal end side (opposite side of the connection portion 18) of the main body 10, Conversely, it may be directed to the drive shaft side (connector 18 side). Thus, the flow most suitable for efficient stirring can be obtained by appropriately setting the ejection direction from the discharge port 14.

  FIGS. 5A and 5B are schematic views showing an example of use of the stirring rotator 1. As shown in these drawings, the stirring rotating body 1 is connected to a driving shaft 20 connected to a driving 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 state. 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.

  By rotating the stirring rotator 1 by the driving device 30, a flow radially spreading from the stirring rotator 1 and a swirling flow (vortex) toward the tip of the stirring rotator 1 are generated as described above. As a result, as shown in FIGS. 4A and 4B, a complicated circulation flow is generated in the stirring object 50, and the stirring object 50 is sufficiently stirred by this circulation flow.

  In order to disperse the staying matter staying at the bottom of the container 40, the tip of the stirring rotor 1 may be brought close to the bottom of the container 40. 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. In addition, when the accumulated matter staying at the corner of the container 40 is dispersed, the tip of the stirring rotating body 1 may be brought close to the corner of the container 40. In the present embodiment, since the main body 10 is configured in a substantially bullet shape, the suction port 12 can be sufficiently brought close to a narrow corner portion.

  In the present embodiment, the main body 10 is configured in a substantially bullet shape, and the colliding member 17 is disposed inside the suction port 12 or the discharge port 14, so that the object to be stirred that passes through the suction port 12 or the discharge port 14 at the time of rotation. Since only 50 collides with the collision member 17, the reaction at the start of rotation hardly occurs. Further, since no sharp protrusions are provided on the outside of the main body 10, the stirring rotator 1 or the container 40 can be damaged or scraped even when the stirring rotator 1 is hit against the wall surface of the container 40. The nature is low. For this reason, 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. It is difficult for scrap and the like to be mixed into the object to be stirred 50.

  In the present embodiment, the suction port 12 is disposed 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 container 40. The suction port 12 is prevented from being blocked even when it is brought into contact with the wall surface. For this reason, the rotating body 1 for stirring can be stably operated even near the wall surface of the container 40.

  Next, other forms of the stirring rotor 1 will be described. FIG. 6A is a front view (side view) showing an example in which the suction port 12 is provided on the drive shaft side. The figure shows an example in which two of the four suction ports 12 are provided on the bottom surface 10a on the drive shaft side. As described above, the suction port 12 may be configured such that a part of the plurality of suction ports 12 is disposed on the distal end side and the remaining part is disposed on the drive shaft side. Further, depending on the application, all of the suction ports 12 may be provided on the drive shaft side.

  By appropriately setting the arrangement of the suction port 12, it is possible to generate an optimal flow according to the application. Further, if the suction port 12 on the drive shaft side is brought close to the liquid surface of the fluid to suck the gas outside the fluid, the outside gas can be actively taken into the fluid. Thereby, gas can be dissolved in the fluid or bubbles can be mixed in the fluid.

  The main body 10 may be provided with a dedicated intake port for sucking the gas outside the object to be stirred 50, and an air passage connecting the intake port and the discharge port 14 may be provided. As described above, when the main body 10 is provided with the air inlet and the air passage, the fluid can be easily obtained by rotating the stirring rotating body 1 in a state where the air inlet is exposed to the outside of the fluid or in contact with a gas outside the fluid. Gases can be dissolved therein, or bubbles can be mixed into the fluid.

  FIG. 6B is a front view (side view) showing an example in which one suction port 12 is provided for a plurality of discharge ports 14. In this example, the flow passage 16 is configured to branch from an axial direction portion 16 a connected to one suction port 12 to a centrifugal direction portion 16 b connected to a plurality of discharge ports 14. In this way, a common suction port 12 may be provided for the plurality of discharge ports 14.

  FIG.6 (c) is the front view (side view) which showed the example which comprised the main body 10 in spherical shape. Thus, the shape of the main body 10 is not limited to the substantially shell shape shown in the above-described example, but is a sphere, a partial sphere, an ellipsoid, a partial ellipsoid, a column, a disk, a cone, Or a truncated cone shape etc. may be sufficient and the shape comprised combining these solid bodies may be sufficient.

  In addition, the shape of the main body 10 is preferably the above-described shape in which the cross section perpendicular to the rotation axis (center axis C) is circular from the viewpoint of safety and collision with the container or the like. The shape is not limited to this, and the cross section perpendicular to the rotation axis (center axis C) may be other than circular. That is, the shape of the main body 10 may be, for example, a polygonal column shape, a polygonal pyramid shape, or a polygonal frustum shape, or may be a shape configured by combining various solids. Further, a plurality of convex portions and concave portions may be provided on the surface of the main body 10.

  Thus, by configuring the main body 10 to have a shape with appropriate irregularities, it becomes possible to generate an appropriate vortex around the stirring rotating body 1, thereby further improving the stirring ability. There are cases where it is possible. Furthermore, in addition to the setting of the shape of the main body 10, the flow around the stirring rotor 1 may be controlled more precisely by appropriately setting the roughness of the surface of the main body 10 and finer uneven shapes. Good. In addition, various colors may be applied to the surface of the main body 10 to improve the design.

  FIG. 7A is a front view (side view) illustrating an example in which the collision member 17 is provided so as to cross obliquely (in a direction having an angle) with respect to the rotation direction of the main body 10. Thus, the stirring ability can be adjusted by appropriately adjusting the transverse direction of the collision member 17.

  FIG. 7B is a front view (side view) illustrating an example in which the collision member 17 is provided so as to cross the rotation direction of the main body 10 in parallel. In this case, it is possible to prevent the collision member 17 from substantially colliding with the agitated object 50 passing through the suction port 12 or the discharge port 14 in the lateral direction.

  FIG. 7C is a front view (side view) showing an example in which a plurality of collision members 17 are provided in parallel at the suction port 12 and the discharge port 14. As described above, a plurality of collision members 17 may be provided in parallel at the suction port 12 or the discharge port 14, and the stirring ability can be adjusted by adjusting the number of the collision members 17.

  The transverse direction of the collision member 17 may be different between the suction port 12 and the discharge port 14. Further, the number of the collision members 17 provided in parallel may be different between the suction port 12 and the discharge port 14. As described above, by changing the configuration of the collision member 17 between the suction port 12 and the discharge port 14, the stirring ability can be adjusted more finely.

  FIG. 8A is a cross-sectional view showing an example in which the collision member 16 is provided in the flow passage 16. Thus, the collision member 17 may be provided not only in the suction port 12 and the discharge port 14 but also in the flow passage 16. In this case, as shown in the figure, a plurality of collision members 17 may be provided in series in the flow direction in the flow passage 16, and the transverse direction is changed so that the respective collision members 17 intersect each other. May be.

  FIG. 8B is a cross-sectional view illustrating an example in which the collision member 17 is configured to protrude toward the inside of the suction port 12, the discharge port 14, or the flow passage 16. The collision member 17 is not limited to the one configured to cross the suction port 12, the discharge port 14, or the flow passage 16, and thus faces the inside of the suction port 12, the discharge port 14, or the flow passage 16. A protrusion configured to protrude may be used. In addition, although the example which comprised the colliding member 17 in flat form is shown in the figure, it cannot be overemphasized that the colliding member 17 may be comprised in other various shapes, such as a pyramid shape and a dome shape, for example. . Alternatively, an appropriate uneven shape may be formed on the inner wall of the flow passage 16 and used as the collision member 17.

  FIG. 8C is a cross-sectional view showing an example in which a collision member 17 is provided in a flow passage 16 configured to branch from one suction port 12 to a plurality of discharge ports 14. In this case, the collision member 17 provided in the axial portion 16 a of the flow passage 16 rotates around the central axis C together with the main body 10. Therefore, as shown in the figure, by providing the flat collision member 17 in the axial portion 16a, the same effect as that of the impeller is exerted on the agitated object 50 flowing in the axial portion 16a. be able to.

  FIGS. 9A to 9C are cross-sectional views illustrating an example in which the collision member 17 is formed in a flat plate shape and is disposed obliquely with respect to the flow direction of the stirring object 50. In these examples, the collision member 17 is formed in a flat plate shape, and the normal direction N of the surface of the collision member 17 is inclined with respect to the flow direction of the object to be stirred 50 (so as to have an angle). It is arranged in the mouth 12, the discharge port 14 or the flow passage 16.

  By doing so, the flow direction of the agitated object 50 passing through the suction port 12, the discharge port 14 or the flow passage 16 can be changed to a predetermined direction. Can be improved. Further, as shown in FIG. 5B, the collision member 17 is caused to cross or protrude in a direction orthogonal to the rotation direction of the main body 10, and the normal direction N of the surface is the flow direction of the object to be stirred 50. If it is arranged so as to be inclined with respect to the main body 10, the flow direction of the stirring object 50 changes in the rotation direction of the main body 10. It is possible to eliminate clogging by appropriately rotating 1 reversely.

  In addition, you may make it change the flow direction of the to-be-stirred object 50 by providing the collision member 17 of curved cross-sectional shape or blade cross-sectional shape. Further, as shown in FIG. 5C, when only one suction port 12 is provided, a spiral collision member 17, a propeller blade, a turbine blade or the like is formed in the axial portion 16a of the flow passage 16. A shaped collision member 17 may be provided.

  FIG. 10A is a cross-sectional view showing an example in which the collision member 17 is configured by projecting the peripheral edges of the suction port 12 and the discharge port 14 inward. As described above, the collision member 17 may be configured by projecting the peripheral edge of the suction port 12 or the discharge port 14 inward. In this case, the peripheral edge of the suction port 12 or the discharge port 14 may be protruded over the entire circumference or may be partially protruded.

  By doing in this way, the collision member 17 may be able to be effectively collided from the lateral direction against the agitated object 50 passing through the suction port 12 or the discharge port 14. In the example shown in the drawing, the blade member 17a is provided on the collision member 17, but the blade member 17a may not be provided.

  FIG. 10B is a cross-sectional view showing an example in which the peripheral edges of the suction port 12 and the discharge port 14 are rounded. Thus, by rounding the peripheral edges of the suction port 12 and the discharge port 14, it is possible to substantially eliminate the collision in the lateral direction against the agitated object 50 passing through the suction port 12 or the discharge port 14. For example, when stirring the object to be stirred 50 that does not want to make the mixed powder particles fine, such as metallic paint, the peripheral edge of the suction port 12 or the discharge port 14 is appropriately rounded as described above. Sufficient stirring can be performed without making the mixed powder particles fine.

  FIGS. 11A to 11C are front views (side views) showing an example in which the shapes (cross-sectional shapes) of the suction port 12 and the discharge port 14 are formed into shapes having corner portions 12a and 14a. In this way, by forming the suction port 12 or the discharge port 14 in a shape having corners 12a, 14a such as rhombuses and triangles, the collision from the lateral direction by the collision member 17 formed by protruding the peripheral edge is more effective. Can be done.

  In this case, as shown in FIGS. 4A and 4B, the shape of the suction port 12 or the discharge port 14 is configured to have corner portions 12a and 14a including the cross-sectional shape of the flow passage 16. Alternatively, as shown in FIG. 6 (c), only the shape of the suction port 12 or the discharge port 14 is formed into a shape having corners 12a and 14a by projecting the collision member 17 from the periphery. You may make it do.

  Needless to say, the suction port 12 and the discharge port 14 may have different shapes, and only one of the suction port 12 and the discharge port 14 may have the corners 12a and 14a. Further, when the suction port 12 or the discharge port 14 is configured to have a shape having the corner portions 12a and 14a, depending on the shape, even if the collision member 17 is not provided, only the corner portions 12a and 14a can be viewed from the lateral direction with respect to the agitated object 50. In some cases, a collision effect can be generated.

  12A to 12C are front views (side views) showing an example of a method of attaching the collision member 17 to the main body 10. First, FIG. 1A shows an example in which the collision member 17 is fitted in the groove portion 10d provided in the main body 10 and is fixed by being pressed by the cover member 70 from the outside. In this example, a groove portion 10d is formed above and below each discharge port 14, and a rod-like collision member 17 is fitted into the groove portion 10d, whereby the collision member 17 is arranged at each discharge port 14. The cover member 70 is configured in a cylindrical shape that is fitted so as to cover the side surface 10 c of the main body 10, and an opening 72 that is substantially the same shape as the discharge port 14 is formed at a position corresponding to each discharge port 14. .

  By fixing the collision member 17 in this manner, the collision member 17 can be easily attached / detached or replaced only by removing the cover member 70 from the main body 10. That is, the collision member 17 can be easily attached / detached or replaced with a different shape as necessary, so that the versatility of the stirring rotating body 1 can be improved.

  Although not shown, a groove portion 10d is formed around the suction port 12, and a hemispherical cover member 70 having an opening 72 at a position corresponding to each suction port 12 is fitted to the bottom surface 10b. Thus, the same fixing method can be adopted for the collision member 17 arranged in the suction port 12. Further, if the groove portions 10d are formed at a plurality of locations around the suction port 12 or the discharge port 14, the crossing direction of the collision member 17 can be changed and fixed.

  FIG. 2B shows an example in which the collision member 17 is provided on the cover member 70. In this example, the cover member 70 is configured in a cylindrical shape that fits so as to cover the side surface 10c of the main body 10 as in the example of FIG. An opening 72 having substantially the same shape as the outlet 14 is formed. The collision member 17 is formed in the opening 72.

  By doing so, the collision member 17 can be provided at the discharge port 14 even in the stirring rotator 1 not provided with the collision member 17 simply by attaching the cover member 70 to the main body 10. In addition, by preparing a plurality of types of cover members 70 having collision members 17 having different shapes and directions, the collision members 17 can be easily formed according to the application of the rotating body for stirring 1 and the properties of the object to be stirred 50. Can be changed. Also in this example, if the hemispherical cover member 70 in which the opening 72 and the collision member 17 are formed at the position corresponding to each suction port 12 is fitted to the bottom surface 10b, the present invention can be applied to the suction port 12. Can do.

  The shape of the cover member 70 is not limited to a cylindrical shape or a hemispherical shape, and an appropriate shape may be adopted according to the shape of the main body 10 and the shapes and arrangements of the suction port 12 and the discharge port 14. it can. Further, the material of the cover member 70 is not particularly limited. For example, if the cover member 70 is made of a soft material such as various types of rubber or resin, the safety of the stirring rotating body 1 can be improved. That is, the cover member 70 can also function as a safety cover.

  FIG. 2C shows an example in which a part of the ring-shaped member 80 attached to the main body 10 is a collision member 17. Thus, the ring-shaped member 80 can be attached to the side surface 10 c of the main body 10, and the portion overlapping the discharge port 14 can be used as the collision member 17. In this case, the collision member 17 can be provided very simply.

  The collision member 17 may be attached to the main body 10 by a known method (for example, adhesion, welding, engagement, screw fastening, etc.) other than the method shown in FIGS. Needless to say, it may be formed integrally with the main body 10.

  Next, a stirring device 2 configured by connecting a plurality of stirring rotors 1 will be described. FIG. 13 is a front view (side view) showing an example of the stirring device 2, and shows an example in which three stirring rotators 1 are connected via a drive shaft 20. As described above, the stirring ability can be further improved by connecting the plurality of stirring rotating bodies 1 in the direction of the rotation axis. In particular, it is effective when the depth of the fluid to be stirred is deep.

  As described above, the stirring rotator 1 according to this embodiment includes the main body 10 that rotates about the rotation axis (center axis C), the suction port 12 provided on the surface of the main body 10, and the surface of the main body 10. And a flow passage 16 that connects the suction port 12 and the discharge port 14. The suction port 12 is disposed closer to the rotation axis than the discharge port 14, and the discharge port 14 is a suction port. Arranged at a position on the outer side in the centrifugal direction from the rotation axis with respect to the port 12, the suction port 12, the discharge port 14 or the flow passage 16 collides with the agitated object 50 passing through the suction port 12, the discharge port 14 or the flow passage 16. An impingement member 17 that can be formed is provided.

  By setting it as such a structure, safe and efficient stirring can be performed regardless of a use. Specifically, by causing the collision member 17 to collide with the object to be stirred 50 that passes through the suction port 12, the discharge port 14, or the flow passage 16, a complicated flow is generated in the object to be stirred 50 to improve the stirring ability. be able to. In addition, it is possible to appropriately crush the lump contained in the object to be stirred without providing a projection such as an impeller outside the main body 10, so that the stirring can be performed more safely and efficiently than before. It can be carried out.

  Further, the collision member 17 is provided so as to protrude toward the inside of the suction port 12, the discharge port 14 or the flow passage 16, or to traverse the inside of the suction port 12, the discharge port 14 or the flow passage 16. Yes. Thus, by making the collision member 17 collide with the object to be stirred 50 without protruding outside the main body 10, safety is impaired while the stirring rotary body 1 has a stirring effect due to the collision. It is possible to prevent problems such as recoil at the start of rotation and chipping or scraping when contacting a container or the like.

  Further, the collision member 17 may be provided so as to protrude or cross in a direction having an angle with respect to the rotation direction of the main body 10. In this case, with the rotation of the main body 10, the collision member 17 can collide with the agitated object 50 passing through the suction port 12, the discharge port 14, or the flow passage 16 from the lateral direction of the flow direction. Thereby, it becomes possible to further improve the stirring ability. Further, the stirring ability can be finely adjusted by appropriately adjusting the angle with respect to the rotation direction.

  Further, the collision member 17 may be provided so as to protrude or cross in parallel with the rotation direction of the main body 10. In this case, since it is possible to prevent the collision member 17 from substantially colliding with the object to be stirred 50 from the lateral direction, efficient stirring can be performed depending on the properties of the object to be stirred 50 and the like.

  Further, the collision member 17 may be configured in a flat plate shape. In this case, by appropriately adjusting the normal direction N of the surface of the collision member 17, the collision mode with the object to be stirred 50 can be changed, and the stirring ability can be finely adjusted. Further, when the collision member 17 is arranged so that the normal direction N of its surface has an angle with respect to the flow direction of the stirring object 50 passing through the suction port 12, the discharge port 14 or the flow passage 16, Since the flow direction of the agitated material 50 can be changed in a predetermined direction, more complicated flow can be generated and the stirring ability can be improved.

  Moreover, the collision member 17 may be provided with the blade part 17a in which the front-end | tip was sharply formed. By doing in this way, since it becomes possible to crush the lump of powder etc. contained in the to-be-stirred thing 50 efficiently, stirring ability can be improved.

  Further, the suction port 12 or the discharge port 14 may be configured in a cross-sectional shape having corner portions 12a and 14a. By doing in this way, the collision from the horizontal direction by the collision member 17 which protruded and comprised the periphery can be made more effective. Further, depending on the shape, the collision effect from the lateral direction with respect to the object to be stirred 50 may be generated only by the corner portions 12a and 14a without providing the collision member 17.

  Further, the stirring device 2 according to the present embodiment is configured by arranging a plurality of stirring rotating bodies 1 in the rotation axis direction. For this reason, the stirring ability can be further increased.

  Although the embodiment of the present invention has been described above, the stirring rotating body and the stirring device of the present invention are not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention. Of course, can be added.

  The stirring rotor and the stirring device of the present invention can be used in the field of stirring of various fluids or mixing of bubbles.
