Description

  The present invention relates to a rotating body for stirring and a stirring device for stirring, mixing, dispersing, and the like of various fluids and other fluids.

  Conventionally, for example, when two or more kinds of fluids are mixed or various powders added to the fluid are uniformly dispersed, an agitator that rotates an impeller in the fluid is used. The impeller is generally provided with propeller blades and turbine blades, and agitation is performed by causing fluid to flow by rotating.

  Many of such agitators are constantly installed and used in a tank that contains a fluid, but in addition to this, for example, a handy type for agitating paint etc. on site immediately before use is also available. Well 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 accommodated, rotates, and performs stirring.

  However, this handy-type stirrer is very dangerous because it rotates an impeller having a sharp blade tip at a high speed, and there is a problem that it needs to be handled with care. 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 agitated material. There was a problem that it was easy to do.

  In addition, 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 thrown into the material to be stirred, When starting the rotation of the car, 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 sediment is included in the object to be stirred, the sediment cannot be dispersed well unless stirring is performed while the impeller is in contact with the bottom wall of the container. There was a problem that debris and shavings generated by contact with the wall surface of the container were likely to be mixed into the object to be stirred.

  In order to solve such a problem, Patent Document 1 discloses a main body that rotates around a rotation axis, an inlet provided on the surface of the main body, an outlet provided on the surface of the main body, an inlet and an outlet. A stirring passage that is disposed at a position closer to the rotation axis than the discharge port, and the discharge port is disposed at a position on the outer side in the centrifugal direction from the rotation shaft than the discharge port. It is disclosed.

  The rotating body for stirring disclosed in Patent Document 1 can perform safe and efficient stirring regardless of the use, and it is difficult to make a vortex on the liquid surface of the object to be stirred, so that quiet stirring without ripples is possible. Is possible.

  As an improvement of Patent Document 1, Patent Document 2 discloses a stirring rotation provided with a collision member formed so as to be able to collide with an object to be stirred that passes through the inside of a suction port, a discharge port, or a flow passage. The body is disclosed.

  As with Patent Document 1, the rotating body for stirring in Patent Document 2 can perform safe and efficient stirring regardless of the use, and can also be used for powders mixed in an object to be stirred. The mass can be crushed.

<First embodiment>
The structure of the rotating body for stirring 1 as a first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing an example of the stirring rotor 1, FIG. 2 is a front view of FIG. 1 showing an example of the stirring rotor 1, and the side view is the same. It is the bottom view of FIG. 1 which showed an example. In FIGS. 1 and 2, a part of the cross section is shown.

  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 fluid member 17 disposed in the suction port 12 and the discharge port 14. In addition, the part of the flow member 17 whose cross section is partly smaller than the other flow member 17 (the width is narrow) is that the flow member 17 having an angle is cut in a cross section as will be described later. This is because it is illustrated.

  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. Accordingly, the stirring rotator 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 this embodiment, unlike an impeller or the like that tends to cause unbalance, it is easy to eliminate vibrations and whirling during rotation.

  The suction port 12 is provided on one bottom surface 10 b (that is, the front end portion of the main body 10) on the opposite side of the connection portion 18 in the main body 10. In the present embodiment, the four suction ports 12 are arranged at equal intervals on the circumference around 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 substantially 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. 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. In other words, the flow passage 16 of the present embodiment includes the suction port side flow passage 16a that is an axial portion in the central axis C direction and the discharge port side flow passage 16b that is a centrifugal direction portion in the central axis C 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. When the flow passage 16 is configured in this way, the suction port flow passage 16a is a place where a flow member 17 that generates a flow of suction described later is disposed, and the discharge port side flow passage 16b is a discharge described later. It becomes a location where the flow member 17 which generates the flow which becomes.

  With such a configuration of the flow passage 16, the flow resistance in the flow passage 16 can be reduced. Therefore, the flow caused by the stirring rotor 1 in cooperation with the flow member 17 described later is further strengthened, and the stirring ability is increased. Can be improved.

  The flow member 17 is a planar member and is provided in each of the suction port 12 and the discharge port 14. The flow member 17 is a member for further generating and strengthening the flow of the object to be stirred that passes through the suction port 12 or the discharge port 14, and will be described in detail later. By adding to the above, more powerful stirring is realized, and at the same time, a lump such as a powder is more reliably crushed.

  In the present embodiment, the flow member 17a provided in the suction port 12 or the suction side flow passage 16a is a planar member provided so as to cross in the centrifugal direction of the central axis C that is the rotation shaft, and The normal does not have only a component in the direction perpendicular (90 °) to the central axis C (specifically, if the flat plate has no curved surface, the normal of the flat plate does not have only the component in the direction perpendicular to the central axis C, In the case of a curved surface, the normal of any part of the curved surface is not the only component in the direction perpendicular to the central axis C, and 17 and 8 (c) provided in 16a of FIG. In the present embodiment, the flow member 17a of the present embodiment is such that the normal line has only a component perpendicular to the central axis C (having no angle other than 90 °). It is configured so that it is not.

  Further, the flow member 17a does not have only a component whose normal line is parallel (0 °) to the central axis C (specifically, if the flat plate has no curved surface, the normal line of the flat plate has the central axis C and the normal line). In a state where only the component in the parallel direction is not obtained, and in the case of a curved surface, no matter which part of the curved surface is normal, only a component in the direction parallel to the central axis C is obtained, which is indicated by 16a in FIG. As in the case of the provided 17, a component whose normal is only a component in a direction parallel to the central axis C (having no angle other than 0 °) does not become the fluid member 17 a of this embodiment). Has been.

  The flow member 17a of the present embodiment is configured such that a portion close to the suction port 12 or a side close to the suction port 12 is arranged on the forward side in the rotation direction after satisfying the above-described conditions. Specifically, as shown in FIG. 2, when the main body 10 is rotated in the direction of the arrow (forward rotation), the angle is set so that the flow member 17a generates a flow that lifts up the object to be stirred. It has become. That is, 17 provided in 16a of FIG. 9A in Patent Document 2 is not disposed on the forward side in the rotational direction of the portion close to the suction port 12, and therefore the configuration of the flow member 17a of the present embodiment is as follows. is not.

  Moreover, 17 provided in 16a of FIG.9 (b) in patent document 2 has an unknown rotation direction, and is not the indication of the structure of the flow member 17a of this embodiment.

  The flow member 17a in FIGS. 1 to 3 is a flat plate, but is not limited to this configuration. For example, the flow member 17a is configured by a curved surface or bent like various impellers (impellers). Even if it is constituted by a flat plate, if the flow member 17a generates a flow that lifts up the agitated object by arranging the portion close to the suction port 1 or the side closer to the advance side in the rotation direction, Any thing is good.

  Further, the above-described flow member 17a of the present embodiment has a configuration in which the normal line does not include only the component in the direction perpendicular to the central axis C, and the normal line does not include only the component in the direction parallel to the central axis C. This is because in such a configuration, the flow member 17a cannot generate a flow that lifts up the object to be stirred. In this respect, the flow member 17a of the present embodiment is simply described in Patent Document 2. It is not a collision member as disclosed.

  In the agitation industry, when the main body 10 connected by the drive shaft 20 and the connecting portion 18 is viewed from the side of the drive device 30 such as a motor, the clockwise direction is the forward rotation direction and the counterclockwise rotation direction. Is generally referred to as reverse rotation, and in the present embodiment, the rotation direction of FIGS.

In the agitation industry, generally, when the agitator is rotated forward, it is normal to generate a downward flow that pushes the object to be agitated toward the bottom of the container. For example, in the homepage of “A stirrer half-century Hanwa Kako Co., Ltd.”, “Reverse rotation stirring that intentionally entrains air” “Normally the direction of rotation of the rotating shaft of the stirrer is clockwise. This normal rotation is called forward rotation.Reverse rotation refers to stirring performed by rotating the stirring shaft (shaft) in the opposite direction, that is, counterclockwise. The major difference between the reverse rotation and the reverse rotation is that the forward rotation generates a pushed down liquid flow, and the reverse rotation generates a scraped liquid flow.The purpose of using the reverse rotation is to mix air to be agitated. It is a stirring technique to be performed. ”

  Similarly, in the aeration stirrer disclosed in Japanese Patent Application Laid-Open No. 2009-247927, as shown in FIGS. 3 and 5 and the description thereof, the impeller attached to the shaft tip is configured to generate a downward flow. ing.

  On the other hand, the flow member 17a of the present embodiment sets the angle so as to generate a flow that lifts up the object to be stirred when the main body 10 is rotated in the forward direction, as opposed to normal. The main feature is that the rotating body 1 cooperates with the function of generating the flow inherently and exhibits a stronger stirring ability.

  Next, in the present embodiment, the flow member 17b provided in the discharge port 14 or the discharge port side flow passage 16b is a planar member provided so as to cross in a direction parallel to the central axis C, and The normal does not only have a component in the direction parallel to the central axis C (0 °) (specifically, if the flat plate has no curved surface, the normal of the flat plate does not have only the component in the direction parallel to the central axis C, In the case of a curved surface, the normal of any part of the curved surface is not in the direction parallel to the central axis C, and the outside of 16b in FIG. 8C in Patent Document 2 (the side far from the central axis C). As in the case of 17 provided in the first embodiment, a component whose normal line is only a component parallel to the central axis C (having no angle other than 0 °) is not the fluid member 17b of the present embodiment). It is configured.

  Further, the flow member 17b has a normal line that is not only perpendicular (90 °) to the central axis C (specifically, if the flat plate has no curved surface, the normal line of the flat plate is only perpendicular to the central axis C). If the surface is a curved surface, the normal of any part of the curved surface is not only perpendicular to the central axis C, and 17 and FIG. 4 (b) provided in 16b of FIG. ) And 17 provided at 16b in FIG. 8C and 17 provided inside 16b in FIG. 8C (side closer to the central axis C), the normal line is only perpendicular to the central axis C (other than 90 °). What does not have an angle) is configured not to be the fluid member 17b of the present embodiment.

  The flow member 17b of the present embodiment is configured such that the portion close to the rotation axis C and the side close to the rotation axis C are arranged on the forward side in the rotation direction after satisfying the above-described conditions. Specifically, as shown in FIGS. 1 and 3, when the main body 10 is rotated in the direction of the arrow (forward rotation), the flow member 17b generates a flow that scrapes the agitated material from the discharge side flow passage 16b. The angle is set so that That is, 17 provided in 16b of FIG. 9A in Patent Document 2 is not arranged on the forward side in the rotation direction with the portion close to the rotation axis C, so the configuration of the flow member 17b of this embodiment is is not.

  Moreover, 17 provided in 16b of FIG.9 (b) in patent document 2 has an unknown rotation direction, and is not the indication of the structure of the flow member 17b of this embodiment.

  The flow member 17b in FIGS. 1 to 3 is a flat plate, but is not limited to this configuration. For example, the flow member 17b is configured by a curved surface or bent like various impellers (impellers). Even if it is composed of a flat plate, what is necessary is that the flow member 17b generates a flow that scrapes the object to be stirred by arranging a portion near or close to the rotation axis C on the forward side in the rotation direction. It can be anything.

  In addition, the above-described flow member 17b of the present embodiment has a configuration in which the normal line is not only a component parallel to the central axis C, and the normal line is not only perpendicular to the central axis C. This is because in such a configuration, the flow member 17b cannot generate a flow that scrapes the object to be stirred. In this respect, the flow member 17b of the present embodiment is disclosed in mere Patent Document 2. It is not a strong collision member.

  Here, the operation of the rotating body for stirring 1 will be briefly described with reference to FIGS. 1 to 4. FIG. 4 is a schematic view showing an example of use of the stirring rotator. The stirring rotating body 1 of the present embodiment 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.

  Specifically, the stirring rotator 1 is connected to a drive shaft 20 connected to a drive device 30 such as a motor, and is used while being immersed in an object to be stirred 50 that is a fluid contained in a container 40. The 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.

  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 suction port side flow passage 16 a and the discharge port side flow passage 16 b flows toward the outside in the radial direction 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, the discharge port 14 and the discharge port side flow passage 16b connected thereto have the suction port 12 and the suction port side flow passage 16a connected thereto. Stronger centrifugal force will work. 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 discharge side flow passage 16b is ejected from the discharge port 14, and the external fluid is sucked into the suction side flow passage 16a from the suction port 12.

  As a result, in the fluid around the stirring rotator 1, a flow spreading radially from the side surface 10 c with the discharge port 14 and a flow toward the tip of the stirring rotator 1 with 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. As a result, as shown in FIG. 4, a complicated circulation flow is generated in the stirring object 50, and the stirring object 50 is sufficiently stirred by this circulation flow.

  Further, when the staying matter staying at the bottom of the container 40 is dispersed, the tip of the stirring rotary body 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 stirred object 50. Further, when the staying 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.

  Further, in the present embodiment, the main body 10 is formed in a substantially bullet shape, and the flow member 17 is disposed on the inner side so as not to protrude from the suction port 12 or the discharge port 14. Even when it hits against the wall surface, the possibility that the rotating body 1 for stirring or the container 40 is damaged or scraped can be reduced. As a result, it is possible to bring the stirring rotator 1 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, as well as fragments of the stirring rotator 1 or the container 40, It is possible to make it difficult for scrap and the like to be mixed into the object to be stirred 50.

  Although the rotation in FIGS. 1 to 4 is a normal rotation, the rotating body 1 for stirring according to the present embodiment is the same as the normal rotation even if the rotating body 1 is rotated in the reverse direction due to the stirring principle described above. The fluid in 16b is ejected from the discharge port 14, and the external fluid is sucked into the suction side flow passage 16a from the suction port 12. However, as described above, the flow member 17a on the suction side flow passage 16a side shown in FIG. 1 to FIG. 4 has an angle so as to generate a flow that lifts up the agitated object when the main body 10 is rotated forward. Since it is the set configuration, when it is rotated in the reverse direction, the portion close to the suction port 12 is not arranged on the forward side in the rotational direction, that is, the configuration of the present embodiment is not used. Will prevent the inhalation of fluid.

  Similarly, the flow member 17b on the discharge side flow passage 16b side has a configuration in which an angle is set so as to generate a flow for scraping the object to be stirred when the main body 10 is rotated forward, so that the flow member 17b is reversely rotated. In such a case, the portion close to the central axis C is not arranged on the forward side in the rotational direction, that is, the configuration of the present embodiment, so that the fluid is prevented from projecting at the discharge port 14.

  In this embodiment, the flow member 17 is provided in both the suction port 12 and the discharge port 14, but the flow member 17 may be provided in only one of the suction port 12 and the discharge port 14. Needless to say. Further, the flow 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.

  Further, in the present embodiment, the flow member 17 is disposed in the vicinity of the inside of the suction port 12 or the discharge port 14 in the drawing, but the present invention is not limited to this and may be provided inside the flow passage 16. A plurality of them may be provided.

  Moreover, it is comprised so that a blade part may be provided in the advance side of the rotation direction of the flow member 17a or the flow member 17b, and it may be made to crush efficiently the lump of powder etc. which are contained in the to-be-stirred thing 50. FIG.

  As described above, the stirring rotator 1 according to the present embodiment is capable of performing safe and efficient stirring as before, and also the flow that is swirled by the fluid member 17a and the fluid that is scraped by the fluid member 17b. More powerful agitation is possible through collaboration.

  Further, the flow that is scraped by the fluid member 17a and the fluid that is scraped by the fluid member 17b generates a complex and powerful turbulent flow at the suction port 12 and the projecting port 14, so that the powder or the like that has not completely melted compared to the conventional case is used. The lump can be reliably crushed, the solid can be dissolved, and the gel can be liquefied.

It is the schematic of the winged member used for FIG. 5 which showed an example.

  According to FIGS. 5 and 6, the stirring rotating body 1 includes a substantially cylindrical main body 10, a single inlet 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, the flow passage 16 formed inside the main body 10 so as to connect the suction port 12 and the discharge port 14, and the fluid member 17 disposed in the suction port 12 or the suction port side flow passage 16 a. ing.

  As shown in FIG. 7, the fluid member 17 in the present embodiment is a wing-like member composed of a plurality of wings 17c and a wing connection portion 17d to which the plurality of wings 17c are radially attached. It is provided in the flow passage 16a.

  The wing-like member shown in FIG. 7 shows a state of being cut from, for example, a metal plate before being attached to the main body 10, and when attaching to the main body 10, the one side 17f of the wing 17c is flat with the wing connecting portion 17d. The other side is twisted while keeping it, and the wing 17c is angled with respect to the plane, and then attached to the main body 10. The reason why the width of the wing 17c shown in FIG. 5 is smaller than the width of the wing 17c shown in FIG. 7 is that the wing 17c in FIG. 5 has an angle with respect to the wing connecting portion 17d.

  Note that the cross-sectional view of FIG. 6 is slightly different from the original cross-sectional view in order to make the attached state of the wing-like member easy to understand. Specifically, although the suction port 12 is a straight line in an accurate cross-sectional view, the shape and angle of the wing 17c and the attached state are illustrated by a curve for easy understanding. Further, in the accurate sectional view, four blades 17c among the eight blades 17c in FIG. 7 are shown in the sectional view. However, since it is difficult to understand, only the two blades 17c on the far side are illustrated. ing.

  In this example, the main body 10 has a substantially cylindrical shape that is wider (that is, flat) in the axial cross-sectional direction than the length in the axial direction. Further, a connection boss portion 19 having a connection portion 18 to which a drive shaft 20 of a drive device such as a motor is connected is provided at the center of the other bottom surface 10a of the main body 10 so as to rotate about the drive shaft 20 as a rotation axis. It is configured. 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 addition, since the connecting portion 18 of the main body 10 in the present embodiment is a through hole, for example, the drive shaft 20 is passed through the connecting portion 18 of the main body 10 where the flow member 17 is not provided, and the main body 10 is left as it is. By inserting the suction side flow passage 16a through the connecting portion 18 of the main body 10 of the present embodiment, the stirring rotator 1 can be configured in multiple stages.

  In this embodiment, the strength of the main body 10 is increased by configuring the main body 10 in 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 | gum, wood, etc., is employable. Further, in the second embodiment, since the form is simpler and easier to process than the first embodiment, the main body 10 can be made of various materials without being limited by the manufacturing method. It is possible.

  In addition, since the main body 10 is configured in a simpler shape as described above, it is possible to reduce the occurrence of unbalance with respect to the rotating shaft, and thus it is very easy to eliminate vibrations and whirling during rotation. .

  The suction port 12 of the present embodiment has a circular shape, and is substantially the rotation center of the drive shaft 20 on one bottom surface 10b (that is, the front end portion of the main body 10) opposite to the connection portion 18 in the main body 10. One is arranged concentrically.

  The discharge port 14 has a circular shape and is provided on the side surface 10 c of the main body 10. In the present embodiment, the four discharge ports 14 are respectively positioned at positions outside the suction port 12 in the radial direction (centrifugal direction) of the main body 10 (positions away from the drive shaft 20 in the direction perpendicular to the drive shaft 20). It is arranged. Further, the discharge port 14 is formed in a direction orthogonal to the drive shaft 20. 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.

  In the present embodiment, the flow passage 16 is configured to branch from one suction port 12 to four discharge ports 14 inside the main body 10. Therefore, one suction port side flow passage 16a and four discharge port side flow passages 16b branched in four directions from the suction port side flow passage 16a are formed in the main body 10. The suction side flow passage 16 a has a substantially cylindrical shape that is substantially concentric with the drive shaft 20. Further, the discharge port side flow passage 16b is connected to the suction port side flow passage 16a on the side opposite to the suction port 12, and is formed in a substantially cylindrical shape perpendicular to the drive shaft 20 and directed toward the centrifugal direction of the main body 10. It has become. That is, the flow path 16 of the present embodiment is similar to the first example in that the suction port side flow path 16a serving as the axial direction portion of the drive shaft 20 and the discharge port side flow path serving as the centrifugal direction portion of the drive shaft 20 are used. 16b.

  Thus, in the present embodiment, the suction port 12, the discharge port 14, and the flow passage 16 can be formed more easily by drilling with a drill or the like than in the first example. 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.

  As shown in FIGS. 5 and 6, the wing-like member as the flow member 17 has the blade tip 17e on the side opposite to the blade connecting portion 17d on one side 17f as the suction port 12 or the suction port side flow passage 16a. They are connected by a known method such as welding, bonding or fitting to a notch. This connection may be made by all of the plurality of blade tips 17e or only a part thereof. This connection may be detachable.

  In the present embodiment, as described above, the flow member 17 as a wing member provided in the suction port 12 or the suction side flow passage 16a includes a plurality of blades 17c and a blade connection portion 17d to which the plurality of blades 17c are attached radially. It is composed of In addition, since the blade connecting portion 17d is disposed on a substantially extended line of the drive shaft 20, each of the plurality of blades 17c is provided so as to cross from the blade connecting portion 17d in the centrifugal direction of the drive shaft 20 that is a rotating shaft. It will be.

  Such a blade 17c does not have only a component whose normal line is perpendicular (90 °) to the central axis C (specifically, if the flat plate has no curved surface, the normal line of the flat plate is perpendicular to the drive shaft 20). In the state where only the directional component is not present, if it is a curved surface, the normal component of any part of the curved surface is not the only component in the direction perpendicular to the drive shaft 20, which is provided in 16a of FIG. As shown in FIG. 8 or a plurality of 17 provided on the 12 side in FIG. 8C, the normal line is only a component perpendicular to the drive shaft 20 (having no angle other than 90 °). Is not the wing 17c of the present embodiment).

  Further, the blade 17c does not have only a component whose normal line is parallel (0 °) to the drive shaft 20 (specifically, if the flat plate has no curved surface, the normal line of the flat plate is parallel to the drive shaft 20). In a state where only the direction component is not present, and in the case of a curved surface, no matter which part of the curved surface is normal, only a component in the direction parallel to the drive shaft 20 is obtained, which is provided in 16a of FIG. As shown in FIG. 17, a component whose normal line is only a component parallel to the drive shaft 20 (having no angle other than 0 °) is not the blade 17 c of the present embodiment). Yes.

  The blades 17c of the present embodiment satisfy the above-described conditions, and each of the plurality of blades 17c crosses in the centrifugal direction of the drive shaft 20 that is the rotating shaft from the blade connection portion 17d, and each The portion of the wing 17c close to the inlet 12 and the side close to the inlet 12 are arranged on the forward side in the rotational direction. Specifically, as shown in FIGS. 5 and 6, when the main body 10 is rotated in the direction of the arrow (forward rotation), the angle is set so that each blade 17 c generates a flow that lifts up the object to be stirred. The configuration is set.

  That is, the flow member 17 as the wing-like member is a member for further generating and strengthening the flow of the stirring object passing through the suction port 12, and is added to the stirring rotating body disclosed in Patent Document 1. Thus, it is intended to achieve stronger stirring and at the same time more reliably crush the lump of powder.

  The blades 17c in FIGS. 5 to 6 are flat plates, but this configuration is not limited. For example, a flat plate that is formed of a curved surface or bent, such as various impellers (impellers). Even if it is configured, the portion close to the suction port 12 or the side close to the suction port 12 is arranged on the forward side in the rotation direction, so that the blade 17c generates a flow that lifts up the agitated object. It can be anything.

  As described above, the flow member 17 as the wing-like member of the present embodiment has a configuration in which the normal line is not only the component in the direction perpendicular to the central axis C, and the normal line is only the component in the direction parallel to the central axis C. This is because the flow member 17a cannot generate a flow that lifts up the object to be stirred in this configuration. In this respect, the flow member 17 as the wing member is merely a patent. It is not a collision member as disclosed in Document 2.

  In addition, since 17 provided in 16a of FIG. 9A in Patent Document 2 is not disposed on the forward side in the rotational direction, 17 of the blade 17c of the present embodiment is not provided. It is not configured.

  Furthermore, 17 provided in 16a of FIG. 9C in Patent Document 2 has an angle in a state provided so as to cross the entire 16a in the centrifugal direction of the drive shaft 20, and is a portion close to the inlet 12 Are arranged on both the forward side and the non-advanced side in the rotational direction. Therefore, the blades 17c of the blades 17c are arranged from the blade connecting part 17d arranged on the substantially extension line of the drive shaft 20 as in the present embodiment. Unlike the configuration in which the portion close to the suction port 12 is arranged on the forward side in the rotation direction, both the flow of scooping up the stirring object and the flow of scooping out are generated, and as a result, the suction of external fluid at the suction port 12 Therefore, stronger stirring cannot be realized.

  Moreover, 17 provided in 16a of FIG.9 (b) in patent document 2 does not disclose the structure of the wing | blade 17c of this embodiment because the rotation direction is unknown.

  In addition, in paragraph 0072 of Patent Document 2, “when only one suction port 12 is provided, the shape of the spiral flow member 17, the propeller blade, the turbine blade, or the like is formed on the axial portion 16 a of the flow passage 16. The collision member 17 may be provided ". However, also in this disclosure, the rotational direction is unknown, and the configuration of the wing 17c of the present embodiment is not disclosed.

  In addition, if it is simply combined, it is natural to combine with a propeller blade, etc., that is common in the stirring industry, and generates a downward flow that rotates the stirrer forward to push the object to be stirred toward the bottom of the container. In the above-mentioned Hanwa Koki Co., Ltd. website, “reverse rotation (generates a liquid flow of rafting)”, which is “reverse rotation stirring that intentionally entrains air”, which is described as being different from usual Even if it is those skilled in the art, the combination of "I want to take in air to the liquid to stir as a purpose" cannot be easily imagined.

  In the first place, in the agitation industry, when the agitator is rotated forward, the reason for combining with a propeller blade that generates a downward flow that the object to be agitated pushes down toward the bottom of the container is ), A large vortex flow is generated in the stirring flow, and the appearance is flashy, but only the swirl flow (flow around the drive shaft 20) generates the necessary upstream and downstream (flow in the drive shaft 20 direction) of the object to be stirred. It is difficult and the efficiency of agitation is poor, and as explained on the website of Hanwa Koki Co., Ltd., when there is no need to intentionally entrain, the mass to be agitated is caused by a large amount of air entrained by the large vortex generated. This is because there is a problem that unnecessary foaming occurs.

  In the stirring rotator 1 described in the present embodiment, the flow that is normally raised as described above is generated in cooperation with the fluid member 17 and the function of generating the flow inherent in the stirring rotator 1. This is because there is a clear purpose of exerting a stronger stirring ability, and in the absence of this purpose, the portion close to the suction port 12 described in the present embodiment is scraped as a forward side in the rotational direction. It is impossible to come up with a configuration that generates a flow of frying.

  In addition, since the configuration that the rotating body for stirring 1 originally has no structure for generating a liquid flow on the bottom surface 10a side that is the liquid surface side of the object to be stirred, the rotating body for stirring 1 does not vortex on the liquid surface of the object to be stirred. This makes it possible to quietly stir without causing undulations. Further, also in the stirring rotator 1 described in the present embodiment, the vortex generated in the fluid member 17 is confined in the flow passage 16 of the stirring rotator 1, so that a propeller blade or the like that generates a normal lifting flow is used. Unlike the above, no large vortex flow is generated in the stirring flow. For this reason, although the rotating body 1 for stirring of this embodiment can perform stronger stirring, the liquid surface of the object to be stirred is less likely to vortex and can be quietly stirred without undulations. , Has great features.

  As described above, according to this embodiment of the second embodiment of the present invention, it is possible to perform safe and efficient agitation, and to cooperate with the flow generated by the flow member 17 as a wing member. More powerful stirring is possible by working.

  Furthermore, in the present embodiment according to the second example of the present invention, as compared with the first embodiment, a plurality of wing portions 17c for generating the flow of the fluid member 17 is provided as shown in FIG. Is easier and more powerful stirring is possible.

  Further, in the present embodiment according to the second example of the present invention, since the diameter of the hole is relatively large because the number of the suction ports 12 is one as compared with the first embodiment, the flow member 17 is provided. It has become easier.

  Further, in the present embodiment according to the second example of the present invention, since the flow member 17 is not individually provided in the plurality of suction ports 12 or the suction-side flow passages 16a, it is different from the first embodiment. Thus, not only processing and connection are easy, but also cleaning is easy.

  Further, in the present embodiment according to the second example of the present invention, since a large number of wing parts 17c that generate the flow to be lifted can be installed, a more complicated and powerful turbulent flow can be generated at the inlet 12, A lump of powder or the like that has not been cut can be reliably crushed, a solid can be dissolved, or a gel can be liquefied.

<Third embodiment>
The structure of the stirring rotating body 1 as a third embodiment of the present invention, which is a modification of the second embodiment, will be described with reference to the drawings. FIG. 8 is a side view showing still another example of the rotating body 1 for stirring. In addition, the same code | symbol is attached | subjected to the location which has the same structure as 2nd Example, and description is abbreviate | omitted.

  According to FIG. 8, the stirring rotating body 1 includes a substantially cylindrical main body 10, a single suction port 12 provided on the surface of the main body 10, and a plurality of discharge ports 14 provided on the surface of the main body 10. The flow passage 16 is formed inside the main body 10 so as to connect the suction port 12 and the discharge port 14, and the fluid member 17 is disposed in the suction port 12 or the suction side flow passage 16 a.

  As shown in FIG. 8, the fluid member 17 in the present embodiment is a wing-like member composed of a plurality of wings 17c (not shown) and a wing connecting portion 17d to which the plurality of wings 17c are radially attached. It is provided in the mouth side flow passage 16a. Note that the side view of FIG. 8 illustrates only the wings 17c on the front side of the sheet of the plurality of wings 17c in order to make it easy to understand the attachment state of the wing-like members.

  In the present embodiment according to the third example, the wing-like member as the flow member 17 is, as shown in FIG. 8, a drive shaft extension 20a provided at the tip of the drive shaft 20 that penetrates the connecting portion 18. In addition, the blade connecting portion 17d is connected by a known method such as welding, bonding, fitting to a notch, or screwing. This connection may be detachable. In the present embodiment, since the diameter of the blade connecting portion 17d is smaller than the diameter of the drive shaft 20, the drive shaft extension 20a is cut so as to become thinner toward the tip.

  Since the blade connection portion 17d is connected to a drive shaft extension portion 20a extended from the drive shaft 20, each of the plurality of blades 17c crosses in the centrifugal direction of the drive shaft 20 that is a rotation shaft from the blade connection portion 17d. Will be provided.

  Similarly to the second example described above, the blade 17c of the present embodiment also has a normal line in a state where each of the plurality of blades 17c crosses in the centrifugal direction of the drive shaft 20 that is the rotating shaft from the blade connecting portion 17d. In addition to the configuration in which the vertical axis is not only the component in the direction perpendicular to the central axis C and the normal line is not only the component in the direction parallel to the central axis C, the portion near or close to the suction port 12 of each blade 17c. It is comprised so that the side may be arrange | positioned at the advance side of a rotation direction. Specifically, as shown in FIG. 8, when the main body 10 is rotated in the arrow direction (forward rotation), the angle is set so that each blade 17c generates a flow that lifts up the object to be stirred. It has become.

  That is, the flow member 17 as the wing-like member is a member for further generating and strengthening the flow of the stirring object passing through the suction port 12, and is added to the stirring rotating body disclosed in Patent Document 1. Thus, it is intended to achieve stronger stirring and at the same time more reliably crush the lump of powder.

  In addition, although the wing | blade 17c in FIG. 8 is a flat plate, this structure is not limited, For example, it is comprised by the curved surface like various impellers (impeller), and is comprised by the bent flat plate. Even if it is, the portion close to the suction port 12 or the side closer to the suction port 12 is arranged on the forward side in the rotation direction, so that any configuration can be used as long as the blades 17c generate a flow to lift the object to be stirred. good.

  Thus, the flow member 17 as the wing-like member of the present embodiment also generates a flow in which the flow member 17a lifts up the object to be stirred, and since it is the same as the second example, description thereof is omitted. It is not a collision member as disclosed in Patent Document 2 alone.

  As described above, according to this embodiment of the third embodiment of the present invention, it is possible to perform safe and efficient agitation, and to cooperate with the flow that is swept up by the flow member 17 as a wing-like member. More powerful stirring is possible by working.

  Furthermore, in the present embodiment according to the third example of the present invention, it is easier to provide a plurality of wing portions 17c that generate the flow of the fluid member 17 to be swirled, as compared with the first embodiment. Powerful stirring is possible.

  Further, in the present embodiment according to the third example of the present invention, since the diameter of the hole is relatively large as compared with the first embodiment, the flow member 17 is provided. It has become easier.

  Furthermore, in the present embodiment according to the third example of the present invention, since a large number of wing parts 17c that generate the flow to be lifted can be installed, a more complicated and powerful turbulent flow can be generated at the inlet 12, A lump of powder or the like that has not been cut can be reliably crushed, a solid can be dissolved, or a gel can be liquefied.

  Moreover, in this embodiment which concerns on the 3rd Example of this invention, it is possible to connect the flow member 17 as a wing-like member beforehand to the drive shaft 20, Compared with a 2nd Example, Not only is the processing and connection easy, but the wing-like member set so that the wing-like member can be cleaned and detachable with the drive shaft 20 removed is further easily cleaned.

  In the second and third embodiments described above, the flow member 17 as the wing-like member does not cover the discharge port side flow passage 16b where the connecting portion becomes the centrifugal direction portion of the drive shaft 20. In other words, it is more powerful if the object to be agitated is configured not to flow into the discharge port side flow passage 16b without passing through the gaps between the plurality of blades 17c or the gap between the blades 17c and the suction port side flow passage 16a. Agitation, reliable crushing of powder and the like by more complicated and powerful turbulent flow in the vicinity of the inlet 12, dissolution of solids, and liquefaction of gel-like substances are possible.

  In the second and third embodiments described above, a blade portion is provided on a portion close to or near the suction port 12 (for example, one side 17f) of the blade 17c arranged on the forward side in the rotation direction. It may be configured so that a lump of powder or the like contained in the object to be stirred can be efficiently crushed.

  Further, in the second embodiment and the third embodiment described above, as in the first embodiment, the portion close to the rotating shaft 20 is on the forward side in the rotational direction in the discharge port 14 or the discharge port side flow passage 16b. You may provide the flow member 17 arrange | positioned.

  Further, in the second and third embodiments described above, the agitating rotor 1 is disposed on the wall surface of the container 40 by disposing the fluid member 17 as a wing-like member on the inner side so as not to protrude from the suction port 12. Also when it hits, it may make it low possibility that the rotating body 1 for stirring or the container 40 will be damaged or scraped.

  In the second and third embodiments described above, the drive shaft 20 has been described as being attached to the bottom surface 10a, which is the opposite surface of the suction port 12. However, for example, the fluid member 17 as a wing member is provided. The drive shaft 20 that has been inserted (or attached) is inserted from the suction port 12 side, and the wing-like member is disposed in the suction port side flow passage 16a, and is then attached to the connection portion 18 that is a through hole. Also good.

  As described above in detail, the stirring rotator 1 according to the present embodiment is capable of performing safe and efficient stirring as in the prior art, and generates a flow inherent in the stirring rotator 1. It is possible to cause the function and the fluid member 17 to cooperate and to exert a stronger stirring ability.

  In addition, since the agitating rotating body 1 in this embodiment can generate a complicated and powerful turbulent flow at the suction port 12 and the projecting port 14 by the flow of the fluid member, the lump such as powder that has not completely melted can be reliably obtained. Crushing, dissolution of solids, and liquefaction of gel-like substances are possible.

  Furthermore, since the stirring rotator 1 in the present embodiment can prevent a large vortex flow from being generated in the stirring flow, it can exert a strong stirring ability and is difficult to form a vortex on the liquid surface of the object to be stirred. A gentle agitation is possible.

  The embodiment of the present invention has been described above, but the rotating body for stirring 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 rotating body 1 in the present embodiment can be used as an impeller of a stirring device.

  Moreover, the rotating body 1 for stirring in this embodiment can also be used as a propulsion device for ships.
