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. in use. 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, 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.

  Moreover, in the stirrer provided with the impeller, there is a problem that the powder particles mixed in the object to be stirred may be pulverized by collision with the impeller. For this reason, it is difficult to sufficiently stir, for example, when it is not desired to make the mixed powder particles finer, such as a metallic paint.

  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 agitated object is caused to flow mainly by colliding the outer wall of the impeller with the agitated object. The above-mentioned problem of recoil at the start of rotation and the problem of pulverization of powder particles in the object to be stirred were not 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.

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

<First Embodiment>
First, the structure of the stirring rotating body 1 according to the first embodiment of the present invention 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. 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 in the main body 10 so as to connect 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 tip 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.

  The shapes (cross-sectional shapes) of the suction port 12 and the discharge port 14 are not particularly limited, but the stirring rotator 1 of the present embodiment is characterized in that the discharge port 14 is configured as a long hole. Specifically, the discharge port 14 of this example has a central axis C direction (or a central axis C direction) when viewed from a direction perpendicular to the cross section of the discharge port 14 as shown in FIG. It is formed in an oval shape with the parallel direction as the longitudinal direction. Although details will be described later, the stirring ability can be improved or adjusted by configuring the discharge port 14 to be a long hole in this manner. In addition, in this embodiment, although the inlet 12 is comprised circularly, as long as it is shapes other than a long hole, other shapes may be sufficient.

  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 (cross-sectional 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.

  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. FIG. 2C is an enlarged view of the discharge port 14. 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.

  Further, in the present embodiment, the discharge port 14 is a long hole whose longitudinal direction is the direction of the central axis C, so that radial flow can be generated over a wide range in the direction of the central axis C. That is, by generating a wide jet from the discharge port 14 in the direction of the central axis C, it is possible to widen the range in the direction of the central axis C of the flow that spreads radially from the rotating body 1 for stirring.

  In order to widen the width of the jet flow from the discharge port 14, the discharge port 14 may be enlarged. However, if the flow rate is simply increased, the flow velocity of the jet flow from the discharge port 14 is reduced, so that the stirring ability is reduced. May end up. Therefore, in the present embodiment, the discharge port 14 is configured as a long hole so that the flow velocity is not lowered while the width of the jet is widened. That is, as shown in FIG. 5C, after setting the longitudinal dimension L of the discharge port 14 according to the range of the jet flow, by adjusting the cross-sectional area of the discharge port 14 by the short dimension S, An appropriate flow rate is maintained.

  By doing in this way, since it becomes possible to expand the range of the flow which spreads radially from the rotating body 1 for stirring without reducing the flow rate, the stirring ability can be improved more than before. Further, by adjusting the longitudinal dimension L and the transverse dimension S of the discharge port 14, the stirring ability can be appropriately adjusted.

  In addition, the discharge port 14 is arranged so as to be shifted in the rotational direction with respect to the suction port 12, and the 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. Further, the discharge port 14 is arranged in the direction of the central axis C, and the portion of the flow passage 16 connected to the discharge port 14 is the tip side of the main body 10 (the side opposite to the connection portion 18) or the drive shaft side (the connection portion 18 side). ). Thus, the flow most suitable for efficient stirring can be obtained by appropriately setting the ejection direction from the discharge port 14. Alternatively, one suction port 12 may be provided for the plurality of discharge ports 14, and the flow path 16 may be branched from the one suction port 12 to the plurality of discharge ports 14.

  FIGS. 3A and 3B 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 so that it does not collide with the agitated object 50 during rotation, so that almost no reaction occurs at the start of rotation. In addition, unlike the impeller and the like, the main body 10 is not provided with a sharp protrusion, and therefore the stirring rotator 1 or the container 40 is damaged even when the stirring rotator 1 is hit against the wall surface of the container 40. The possibility of scraping or scraping 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. First, FIGS. 4A to 4C are diagrams showing an example in which the flow passage 16 is configured to gradually expand or contract toward the discharge port 14. In addition, the figure (a) is a front view (side view), and the figure (b) and (c) are bottom views.

  In this embodiment, since the discharge port 14 is configured as a long hole having a shape different from that of the suction port 12, the cross-sectional shape of the flow passage 16 needs to be changed midway. In this case, the stagnation in the flow path 16 is eliminated by configuring the flow path 16 so as to gradually expand or contract in accordance with the longitudinal dimension L and the short dimension S of the discharge port 14. The flow can be made smooth.

  Here, FIG. 5A shows an example in which the centrifugal direction portion 16b of the flow passage 16 is gradually enlarged in accordance with the longitudinal dimension L of the discharge port 14. FIG. 4B shows an example in which the centrifugal direction portion 16b of the flow passage 16 is gradually enlarged in accordance with the short-side dimension S of the discharge port 14, and FIG. The example which reduced gradually the centrifugal direction part 16b of the flow path 16 according to the dimension S is shown. Needless to say, the axial portion 16a of the flow passage 16 may be gradually enlarged or reduced.

  FIGS. 5A to 5C and FIGS. 6A to 6C are diagrams showing an example in which the discharge port 14 is configured as a long hole whose longitudinal direction is a direction orthogonal to the central axis C. FIG. FIGS. 5A and 5C and FIGS. 6A and 6B are front views (side views), and FIGS. 5B and 6C are bottom views.

  As shown in detail in FIG. 5A, the discharge port 14 of this example is a length having a direction perpendicular to the central axis C as a longitudinal direction when viewed from a direction perpendicular to the cross section of the discharge port 14. It is formed in a circular shape. Depending on the application of the rotating body 1 for agitation, efficient agitation can be performed by configuring the discharge port 14 in such a long hole.

  For example, when it is necessary to perform efficient stirring without making the liquid level of the object to be stirred 50 undulate, the strength of the swirl flow toward the front end portion (that is, the suction port 12) of the rotating body 1 for stirring is maintained. On the other hand, it is effective to weaken the flow spreading radially from the rotating body 1 for stirring.

  In such a case, if the discharge port 14 is configured as a long hole whose longitudinal direction is the direction orthogonal to the central axis C, the discharge port 14 is expanded (extended) in the rotation direction of the stirring rotor 1. Therefore, the flow velocity can be reduced without expanding the range in the direction of the central axis C of the flow that spreads radially from the rotating body 1 for stirring. If the cross-sectional area ratio between the suction port 12 and the discharge port 14 is set appropriately, the strength of the swirling flow toward the tip of the stirring rotator 1 can be maintained.

  Also in this example, the strength and range of the flow that radiates from the stirring rotator 1 can be adjusted by appropriately setting the longitudinal dimension L and the transverse dimension S of the discharge port 14. Further, as shown in FIGS. 5B and 5C and FIG. 6A, at least a part of the flow passage 16 is gradually formed in accordance with the longitudinal dimension L and the transverse dimension S of the discharge port 14. By being configured to expand or contract, the flow in the flow passage 16 can be made smooth.

  FIG. 5B shows an example in which the centrifugal direction portion 16 b of the flow passage 16 is gradually enlarged in accordance with the longitudinal dimension L of the discharge port 14. 5C shows an example in which the centrifugal direction portion 16b of the flow passage 16 is gradually enlarged in accordance with the short dimension S of the discharge port 14, and FIG. 6A shows the short direction of the discharge port 14. The example which reduced gradually the centrifugal direction part 16b of the flow path 16 according to the dimension S is shown.

  6B and 6C show an example in which the position of the discharge port 14 with respect to the position of the suction port 12 is shifted in the rotational direction. By shifting the position of the discharge port 14 in this way, the direction of the jet flow from the discharge port 14 can be appropriately changed, so that the state of the flow spreading radially from the rotating body for stirring 1 can be adjusted more finely. Can do.

  FIGS. 7A to 7C are front views (side views) showing examples of other forms of the discharge port 14. FIG. 4A shows an example in which the discharge port 14 is formed in an oval shape having a direction having an angle with respect to the central axis C as a longitudinal direction when viewed from a direction perpendicular to the cross section of the discharge port 14. Show. Thus, by arranging the discharge port 14 obliquely with respect to the central axis C, the jet flow from the discharge port 14 can be made a more complicated flow in combination with the rotation of the rotating body 1 for stirring. Therefore, the stirring ability can be improved. That is, in the present embodiment, the stirring ability can be appropriately adjusted by adjusting the longitudinal direction along with the longitudinal dimension L and the transverse dimension S of the discharge port 14 configured as a long hole. ing.

  FIG. 2B shows an example in which the discharge port 14 is formed in a rectangular shape. FIG. 3C shows an example in which the discharge port 14 is formed in an oval shape curved in an arc shape. Thus, the shape of the discharge port 14 can employ various shapes such as a rectangular shape, an elliptical shape, and a polygonal shape other than the oval shape shown in the above example. Moreover, the shape of the discharge port 14 may be a shape in which an oval, a rectangle, or the like is curved. When the discharge port 14 has a curved shape, it may have a U-shaped, V-shaped, W-shaped, or S-shaped shape in addition to the arc shape.

  FIG. 8A 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. 8B is a front view (side view) showing an example in which the stirring rotator 1 is configured to be able to capture foreign matter. In the figure, an example in which a filter 60 for capturing foreign matter such as dust is provided in the vicinity of the discharge port 14 of the flow passage 16 is shown.

<Second Embodiment>
Next, the stirring rotator 2 according to the second embodiment of the present invention will be described. The rotating body 2 for stirring of the present embodiment is characterized in that the suction port 12 is configured as a long hole, and other basic configurations and operations are the same as those of the first embodiment. Therefore, the same portions are denoted by the same reference numerals in the drawings and the description thereof is omitted, and only portions different from the first embodiment will be described below.

  FIG. 9A is a plan view showing an example of the stirring rotator 2, and FIG. 9B is a front view (side view) showing an example of the stirring rotator 2. (C) is a bottom view showing an example of the rotating body 2 for stirring.

Can do. Moreover, since it becomes possible to adjust the state of the turbulence of the jet flow from the discharge port 14, the stirring ability can be adjusted. That is, in the present embodiment, the stirring ability can be adjusted appropriately by adjusting the longitudinal direction along with the longitudinal dimension L and the transverse dimension S of the suction port 12 configured as a long hole. ing.

  FIG. 11A shows an example in which the suction port 12 is formed in a rectangular shape. FIGS. 7B and 7C show an example in which the suction port 12 is formed in an elliptical shape curved in an arc shape. As described above, the shape of the suction port 12 may employ various shapes such as a rectangular shape, an elliptical shape, a polygonal shape, and the like other than an oval shape. In addition, the shape of the inlet 12 may be an elliptical shape, a rectangular shape, or the like. In addition to an arc shape, the shape of the suction port 12 is curved in a U shape, a V shape, a W shape, or an S shape. It may be a shape.

  Here, as shown in FIG. 5B, the suction port 12 is configured to have an arcuate shape and is arranged so that the longitudinal direction is a tangential direction of the circumference centered on the central axis C. As a result, the suction port 12 can be brought closer to the central axis C without reducing the cross-sectional area. In addition, as shown in FIG. 5C, the suction port 12 is arranged so that the longitudinal direction is at an angle with respect to the tangential direction of the circumference around the central axis C, and appropriately By curving, the state of the swirling flow toward the suction port 12 and the state of the turbulence of the jet flow from the discharge port 14 can be adjusted more finely.
