[0001]

[Industrial applications]

 The present invention relates to an emulsification disperser, and more particularly, to an emulsification disperser that emulsifies and disperses a treated material.

[0002]

[Prior art and its problems]

 Heretofore, as this type, a so-called one-pass type emulsion disperser capable of continuous processing has already been known. That is, the conventional emulsification disperser has a dispersion chamber, in which a dispersion blade that is rotated by an external drive source is arranged, and when the processed material is introduced into the dispersion chamber from one side, When passing through the dispersion chamber, the processed product is dispersed at the same time as emulsification by the rotating dispersion blade, and then the emulsion is sequentially discharged to the other side. Therefore, if the processed product is continuously added from one side, the dispersion / emulsification process is sequentially performed while passing through the dispersion chamber, and the product as an emulsion is continuously obtained on the other side. .

However, such an emulsifying disperser capable of continuous treatment may not be able to obtain a good quality product.

That is, since the processed product that has been introduced is processed by passing through the dispersion chamber only once, it may be discharged while the emulsification / dispersion process by the dispersion blade is insufficient depending on the property of the processed product. In some cases, the product with the target particle size could not be obtained. Also, in this case, it was not suitable for low-volume, high-mix production, which was a problem.

An object of the present invention is to solve the above problems and to provide an emulsifying disperser capable of performing batch processing and obtaining a homogeneous product.

[0006]

[Means for Solving the Problems] In order to solve the above problems, the first invention is, as a first invention, a vertical casing having a dispersion chamber, and a rotating shaft vertically installed in the central portion. A dispersion member provided in the dispersion chamber, and an axial flow pump member that is provided in a lower portion of the casing in communication with the dispersion chamber and is driven by rotation of the rotating shaft. Formed by a stator fixed to the housing and a rotor fixed to the rotating shaft and rotating relative to the stator, and when the casing is inserted into a container containing the processed product, the processed product is It is emulsified and dispersed between the stator and the rotor in the dispersion chamber and then returned to the container via the axial flow pump member. In addition, as a second invention including the first invention, the dispersion member has an annular protrusion having a radial groove formed on the surfaces of the stator and the rotor that face each other, and one protrusion of the dispersion member is formed. The parts are located between the projecting parts on the opposite side and are close to each other, and the workpiece is subjected to shearing force and repeated pressure fluctuations between the stator and the rotor. Is what you are doing. In addition, as a third invention including the first invention, the casing is formed in a double wall structure, and a heat medium or a refrigerant body is allowed to flow between the walls. Is.

[0007]

[Action]

 This device adopts the above-mentioned means, and when the casing is inserted and immersed in the container containing the processed product, the processed product introduced from the container to the casing is emulsified and dispersed in the dispersion chamber of the casing. After that, it is discharged to the bottom of the container by the action of the axial pump member. Therefore, during operation, the processed material is constantly circulated in the container so as to pass through the casing, and the emulsification / dispersion processing is performed in the circulation process, resulting in the progress of the processing. .

Further, according to this invention, batch processing can be performed. That is, since the circulating flow of the processed product is generated in the container by the action of the axial flow pump member, the circulation of the processed product causes the dispersion member to repeat the emulsification / dispersion process many times. Become. In this case, the operating time can be set arbitrarily, so by setting the operating time according to the property of the processed material, it becomes possible to arbitrarily determine the number of processing times by the circulation flow. A homogeneous and high-quality emulsion / dispersion having a desired viscosity can be easily obtained.

Further, in the second device, the processing efficiency can be improved. That is, since the dispersion member is formed of the stator and the rotor, the circulation flow of the processed material is subject to shearing force and repeated pressure fluctuations when passing between the stator and the rotor. , Is strongly emulsified and dispersed.

Further, in the third invention, the structure can be simplified. That is, since the casing has the double-wall structure, the heat medium or the refrigerant body that flows between the walls acts on the object to be treated from both inner and outer wall surfaces of the casing. In other words, the medium heats or cools the processed material in the dispersion chamber from the inner wall of the casing and the processed material existing between the container and the casing from the outer wall of the casing. Can be very rational.

【Example】

 Embodiments of the present invention shown in the drawings will be described below. FIG. 1 is a diagram showing an embodiment of an emulsification disperser according to the present invention. That is, in the emulsification disperser shown in FIG. 1, a casing 11 having a dispersion chamber D is provided with a rotating shaft 5 and a dispersion member 7, and an axial flow pump member 18 is provided at the bottom of the casing 11, for dispersion treatment. By inserting the casing 11 into the container 2 in which the processed product C to be processed is placed, the processed product C introduced into the dispersion chamber D is emulsified and dispersed by the dispersion member 7, and then the emulsified / dispersed product is stored in the container. It is designed to be returned to within 2.

In FIG. 1, a container 2 has a vertical cylindrical shape with an upward opening, into which a processed material C to be emulsified / dispersed is placed and a casing 11 described later can be inserted. It has a size of the order.

The casing 11 has a vertical cylindrical shape with both ends open, and an annular holding plate 8 having a predetermined inner diameter is located in the upper opening and is fixed by a bolt 22. The space surrounded by the holding plate 8 and the casing 11 is formed as a dispersion chamber D.

At this time, the casing 11 has a double wall structure and a flow passage is formed in the wall, and the support 6 is connected to the casing 11.

The support 6 is a tubular member capable of passing water, and includes a support A6a for supplying a heat medium or a refrigerant body into the wall of the casing 11, and a support A6a for discharging the supplied heat medium or the refrigerant body. It is formed with the support B6b. At this time, one end of the support A6a is connected to the inlet 21a formed at the upper end of the casing 11 in a conductive state, and the other end is connected to the external pipe. The support B6b has one end connected to a discharge port 21b formed at a position different from the introduction port 21a at the upper end of the casing 11 in a conductive state, and the other end thereof connected to an external pipe. Connected to. A conduit 21 disposed inside the wall of the casing 11 is connected to the inlet 21a, and the conduit 21 guides the medium supplied through the support A6a to the bottom of the casing 11 inside the wall. .

The upper ends, which are the other ends of the supports 6a and 6b, are attached to a frame 3 of a lifting device (not shown) installed outside the container. Therefore, the casing 11 is held in a state of being suspended from the frame 3 by the support 6, and the frame 3 is moved up and down together with the support 6 and the casing 11 by driving the lifting device.

A rotating shaft 5 rotatably attached to the bearing portion 4 of the frame 3 and vertically movable integrally with the casing 11 is vertically provided in the casing 11 in a state of being aligned with the axial center of the casing 11. The lower end portion thereof projects below the lower end surface of the casing 11. A V-shaped pulley 1 is attached to the upper end of the rotary shaft 5, and a belt is suspended between the pulley 1 and an external drive source (not shown), so that the rotary shaft 5 drives the drive source. It is designed to rotate in conjunction with. Further, at this time, since the rotary shaft 5 is arranged in a state of being inserted inside the holding plate 8 provided in the upper opening of the casing 11, an annular gap e1 is formed in the inserting portion. As a result, the dispersion chamber D and the outside can be electrically connected to each other through the gap e1, and the gap e1 serves as a flow path for the object to be treated C.

As shown in FIG. 2, a dispersion member 7 including a rotor 9 and a stator 10 is provided at a portion of the rotating shaft 5 located inside the dispersion chamber D of the casing 11. As shown in FIGS. 3 to 5, the stator 10 forming one side of the dispersion member 7 has a disc-shaped ring shape, and one end surface of the stator 10 has a sloped surface on the inner peripheral side. A plurality of annular protrusions 10a are formed concentrically. The protrusion 10a of the stator 10 is formed with a plurality of grooves 10b that are radially and equally distributed in the radial direction, and as a result, the protrusion 10a has a comb-shaped ring as a whole.

As shown in FIGS. 6 to 8, the rotor 9 forming the other side of the dispersion member 7 is in the shape of a disc-shaped ring, and one of its end faces has an inclined surface on the outer peripheral side. A plurality of annular projections 9a are formed in a concentric shape. The rotor 9 has a protrusion 9a formed with a plurality of grooves 9b which are arranged radially in a radial direction, and as a result, the protrusion 9a has a comb-shaped ring as a whole.

The stator 10 is attached to the casing 11, and the rotor 9 is attached to the rotating shaft 5. As shown in the figure, the stator 10 is fixed to the casing 11 with bolts 19 and 22 in a state where the outer peripheral end thereof is sandwiched by a holding plate 8 and a mixed flow case 14 (described later) via a distance piece 12. . The rotor 9 has its inner peripheral end fixed to the rotary shaft 5 together with the key 13, and is arranged in the dispersion chamber D so as to face the stator 10. At this time, as shown in FIG. 9, the mounting positional relationship between the stator 10 and the rotor 9 is such that the protrusion 10a of the stator 10 is positioned between the protrusions 9a of the rotor 9 and 9a. The protrusions of the rotor 10 and the rotor 9 are inserted close to each other so that a flow path is formed between the protrusion 10a of the stator 10 and the protrusion 9a of the rotor 9 by a slight annular gap e. Leave.

In the figure, the dispersion member 7 is formed by three pairs of the stator 10 and the rotor 9, but at least one pair may be formed. In this case, since the distance piece 12 is interposed between each of the stators 10 and 10, in order to adjust the distance e between the protrusions 9a and 10a, the length of the distance piece 12 should be selected appropriately. It's good.

An axial pump member 18 formed of a mixed flow case 14 and mixed flow vanes 15 is provided below the casing 11. The mixed flow case 14 forming one of the axial flow pump members 18 is in the shape of a truncated cone whose diameter expands downward, and its small diameter opening allows communication with the dispersion chamber D. Then, it is positioned on the bottom surface of the bottom of the casing 11, and is fixed with a bolt 19 while the axis of the mixed flow case 14 and the axis of the casing 11 are aligned.

As shown in FIG. 10, the mixed flow blade 15 forming the other side of the axial flow pump member 18 has a fixing portion 15b fixed to the lower end portion of the rotary shaft 5 protruding downward from the lower end surface of the casing 11. , A plurality of blade portions 15a that are radially attached to the fixed portion 15b so as to extend radially outward with the axis of the rotary shaft 5 as the center and that are integrally rotatable with the rotary shaft 5. At this time, the fixing portion 15b is attached to the rotary shaft 5 together with the key 13a, and is fixed by the bolt 17 via the attachment plate 16. The fixed portion 15b and the blade portion 15a are provided inside the mixed flow case 14. In order to facilitate the generation of axial flow and oblique flow, it is desirable that the blade portion 15a is arranged with the normal line on the rotational direction side slightly inclined downward, but the normal line is horizontal. There is no problem even in the state.

The tip portion of the blade portion 15a is formed in a shape corresponding to the inner surface of the mixed flow case 14, and the tip portion is separated from the mixed flow case 14 at a predetermined interval when the blade portion 15a is rotated. In the state, it will orbit along the inner surface. In this case, it is desirable that the lower end portion of the blade portion 15a be positioned such that its tip end portion is located above other portions.

Further, the guide vanes 20 are attached to the outer wall of the mixed flow case 14 in an evenly arranged state in such a manner that they are perpendicular to the rotation direction of the blade portion 15a, and the lower end portion of the guide vanes 20 is mixed with the mixed flow. The case 14 is made to project below the lower opening. In the figure, the axial flow pump member 18 is shown as a combination of the oblique flow case 14 and the oblique flow vane 15 as a preferred example, but it goes without saying that an axial flow vane may be used instead. That is.

Next, the operation of the above will be described. This emulsification disperser is configured as described above, and when the casing 11 is inserted into the container 2 containing the processed product C to be emulsified, the processed product C is introduced into the dispersion chamber D from above the casing 11. After being emulsified and dispersed here, the emulsified / dispersed product is returned from the lower opening of the mixed flow case 14 into the container 5, whereby the processed product C passes through the casing 11 in the container 2. It is designed to perform emulsification / dispersion processing while circulating.

First, in the container 2, a slurry-like processed material C, which is a raw material, is placed. Then, when an elevating device (not shown) is driven to move down the frame 3 located above, the casing 11 suspended by the support 6 moves down together with the frame 3, and the casing 11 moves inside the container 2. Inserted in. In this case, since the flow path for introducing the processed material C into the dispersion chamber D is formed by the annular gap e1 opening to the upper part of the casing 11, the amount of the processed material C is such that the casing 11 is inserted into the container 2. In such a case, the casing 11 is secured such that it is completely immersed in the processed material C.

Then, the rotary shaft 5 is rotated by driving an external drive source (not shown). Then, the processed material C existing above the holding plate 8 in the container 2 flows into the dispersion chamber D through the gap e1 between the holding plate 8 and the rotating shaft 5. In the dispersion chamber D, the treated material C is emulsified and dispersed by the action of the dispersing member 7, and then the emulsified / dispersed substance is sucked from the lower opening portion of the mixed flow case 14 by the suction action of the axial flow pump member 18. It is designed to be discharged into the container 2.

Here, the mixed flow blades 15 of the axial flow pump member 18 rotate together with the rotary shaft 5 so as to discharge the processed material C existing between the blade portions 15a, 15a outward in the radial direction. As a result, negative pressure is generated in the shaft center and suction force can be obtained. Further, the mixed flow case 14 that encloses the outer circumference of the mixed flow blade 15 has a cylindrical shape whose diameter expands downward, and since the inner surface is a sloped surface, the mixed flow blade 15 rotates outward in the radial direction. The discharged processed material C is guided downward by the inner surface of the mixed flow case 14, whereby a large amount of the processed material C flows in the axial direction (axial flow), and the processed material in the distribution chamber D is discharged. At the same time as C is sucked into the mixed flow case 14, it is discharged into the container 2 through the lower opening.

When the above operation is performed for a predetermined time, the entire processed material C circulates in the container 2 so as to pass through the casing 11, and the emulsification / dispersion processing is performed in the dispersion chamber D in the circulation process. It will gradually progress. As a result, an emulsion / dispersion having a predetermined particle size can be obtained.

During the above operation, the heat medium or the coolant is supplied from the support A6a to the flow passage formed in the wall of the casing 11, and the heat medium or the cooling medium supplied in the flow passage is supplied. Since the medium is discharged to the support B6b, the heat medium or the refrigerant body constantly circulates in the wall of the casing 11. As a result, the processed product C in the casing 11 and the processed product C in the container 2 are simultaneously heated or cooled by the medium flowing in the wall of the casing 11, so that the processed product C is always suitable. The temperature is kept so that the emulsification / dispersion process can be made uniform and the efficiency can be improved.

Further, the circulating flow of the processed material C generated in the container 2 during the operation may circulate in the container 2 around the rotating shaft 5 due to the rotation of the oblique flow blades 15 of the axial pump member 18. However, due to the existence of the guide vanes 20 provided on the outer wall of the mixed flow case 14, the processed product C is always rectified in the axial direction when passing through the guide vanes 20. A circulating stream of C can be obtained. Further, the mixed flow blades 15 provided in the lower portion of the casing 11 also have an action of stirring the processed product C existing at the bottom of the container 2 when rotating, so that the processed product C in the container 2 can be made uniform. It is useful.

And, in the above-mentioned emulsification disperser, batch processing can be performed.

That is, the axial flow pump member 18 is provided in the lower part of the casing 11 in which the dispersion member 7 is provided in the dispersion chamber D, and the casing 11 is inserted into the container 2 in which the processed material C is contained. While the processed product C is circulated in a large amount so as to pass through the dispersion chamber D of the casing 11, the processed product C is emulsified and dispersed in the dispersion chamber D which is one process of the processed product C. Since the emulsion is repeatedly emulsified and dispersed in the container 2, the processed products can be collectively processed.

That is, by the action of the axial flow pump member 18 provided in the lower portion of the casing 11, the processed material C existing in the dispersion chamber D is sucked into the mixed flow case 14 side, and then the container from the lower opening thereof. Since it is designed to be positively discharged toward the bottom of the container 2, the processed material C discharged to the bottom of the container 2 moves upward while passing outside the casing 11 in the container 2, It is again introduced into the dispersion chamber C from the upper opening of the casing 11, and the treatment is further advanced in the dispersion chamber D. As a result, the processed product C can be emulsified / dispersed many times by forming a large circulation flow in the container 2, and the emulsification / dispersion can be made uniform.

Therefore, the above-mentioned emulsification disperser adopts the batch processing method, so that regardless of the property of the processed material C at the raw material stage, it is possible to set a necessary and optimum operating time according to its characteristics. For example, it is possible to obtain a product having a target particle size in perfect condition.

Further, in the above-mentioned emulsification / dispersion machine, the emulsification / dispersion processing of the processed product C can be efficiently performed.

That is, the dispersion member 7 provided in the dispersion chamber D includes a stator 10 having a protrusion 10a having a radial groove 10b formed therein and a protrusion 9a having a radial groove 9b formed therein. The processed product C introduced into the dispersion chamber D is subjected to a strong emulsification / dispersion action when passing between the stator 10 and the rotor 9 by being formed by the rotor 9 provided therein. Has become.

That is, when the rotor 9 is rotated with respect to the stator 10 by the rotating shaft 5, the object to be treated C existing in the groove 9b of the rotor 9 is given a centrifugal force and is discharged outward in the radial direction. As a result, the processing object C existing in the vicinity of the rotating shaft 5 in the dispersion chamber D moves outward while sequentially passing through the grooves 9b of the rotor 9 and the grooves 10b of the stator 10 alternately. Therefore, when the processed material C in the dispersion chamber D passes between the stator 10 and the rotating rotor 9, there is a gap between the protruding portion 9a of the stator 10 and the protruding portion 10a of the rotor 9. In the channel formed by e, a strong shearing force and repeated pressure fluctuations are received, and this action strongly emulsifies and disperses the treated material C.

At this time, the processed material C in the container 2 forms a large amount of circulating flow by the action of the axial flow pump member 18, and while staying in the dispersion chamber D, it is tens to hundreds of times. As a result, the synergistic effect of these two products makes it possible to obtain a very uniform and high-quality product.

Further, in the above emulsifying disperser, post-treatment can be easily performed.

That is, after the emulsification / dispersion process is completed, if the container 2 and the casing 11 are emptied and then a slight operation is performed, the treated product C remaining in the casing 11 easily drops, so that almost complete treatment is achieved. The product can be collected. Further, when the casing 11 is washed, if the casing 11 is inserted and dipped in another container containing a solvent and the like, and the operation is performed in that state, the inside of the casing 11 will be washed cleanly. Therefore, it is not necessary to disassemble the casing 11, and the cleanability can be improved. Therefore, when the color of the processed product C is changed, the work is very simple, and it is most suitable for the small-quantity multi-product production.

Furthermore, the structure of the above emulsification disperser can be simplified.

That is, the casing 11 has a double wall structure, a medium flow passage is formed between the walls for efficiently performing emulsification / dispersion processing, and the casing 11 is a container in which the processed material C is contained. By immersing the medium in the casing 2, the medium flowing between the walls of the casing 11 effectively acts on both the treated substance C in the container 2 and the treated substance C 1 in the casing 11 from both the inner and outer wall faces. As a result, this eliminates the need to separately provide a medium flow passage in both the container 2 and the casing 11. Further, since the support 6 for suspending the casing 11 is also used as the pipe for circulating the medium, the use of the pipe material can be suppressed to the minimum, and the pipe design can be simplified. Therefore, this emulsifying disperser can have a simplified structure on the assumption that the quality of the product is ensured.

In the case of the above-mentioned emulsification disperser, if a plurality of containers 2 are facilitated and wheels are provided on the lower surfaces of the bottoms of the containers 2 to make them movable, each time the emulsification / dispersion process of the processed product C is completed, If the casing 2 is sequentially moved to insert the casing 11 into the next container 2, continuous processing work can be performed, so that the work efficiency is improved.

In general, in order to obtain a good quality product with an emulsifying disperser, it is important to efficiently emulsify and disperse according to the properties of the treated product C. In the emulsifying disperser according to the present invention, Since a large circulating flow of the processed material C is generated in the container 2 for batch processing, the necessary and optimum processing time for the processed material C can be set arbitrarily and easily. Further, if the length of the distance piece 12 is changed, the gap e between the protruding portion 10a of the stator 10 and the protruding portion 9a of the rotor 9 can be arbitrarily adjusted, so that it is necessary according to the viscosity of the processed material C and the like. It is possible to apply shearing force and pressure vibration of various magnitudes. Further, as the emulsification / dispersion method, the stator 10 and the rotor 9 are used to apply shearing force and pressure vibration to the object to be processed C, so that a very effective process can be performed. .

[Effect of device]

 As described above, according to the present invention, the axial pump member is provided in the lower part of the casing having the dispersion chamber, and when the casing is inserted into the container containing the processed substance, the processed product is emulsified in the dispersion chamber. Since the product is dispersed and then returned to the container, the product to be treated circulates in a large circulation flow. As a result, the product can be processed in batches, and the quality and uniformity of the product can be improved. Therefore, it is possible to flexibly deal with small-lot production of a wide variety of products.

Further, the dispersion member provided in the dispersion chamber is formed by the stator and the rotor, and the strong shearing force and repeated pressure fluctuations generated between the both strongly emulsify and disperse the processed material. As a result, the processing efficiency can be improved.

Furthermore, by making the casing have a double-wall structure and circulating the medium between the walls, the medium can effectively act on the object to be treated from the inner and outer walls of the casing. This has the effect of simplifying the overall structure.
