Description

  The present invention relates to a multifunctional mixing apparatus that mixes a plurality of substances.

  In recent years, use of carbonated water in which carbon dioxide gas is dissolved in water or warm water has been attempted. For example, carbonated water has long been known to be effective in restoring fatigue and promoting blood circulation, and has been widely used in the fields of medicine and beauty. Also in the industrial field such as the semiconductor industry, washing with carbonated water lowers the electrical resistivity of the surface and lowers the electrostatic charge. Furthermore, sterilization and use in agriculture and livestock industry are also being studied.

  Therefore, development of an apparatus capable of producing carbonated water having a high concentration more stably has been underway. As an apparatus for producing carbonated water, for example, a plurality of agitation formed on the inner peripheral surface of a carbon dioxide gas dissolving section for dissolving carbon dioxide gas in water or warm water, which is perpendicular to the central axis of the container and shorter than the inner diameter of the container There has been proposed one in which the barriers for use are shifted from each other in the central axis direction (see, for example, Patent Document 1).

Japanese Patent No. 4711227

  Although development of a carbonated water production device has been promoted in this way, it is hoped that a device capable of easily producing high-concentration carbonated water with a low carbon dioxide concentration and a stable carbon dioxide concentration will be desired. It was rare. In addition, not only in carbonated water, but also in the case of mixing a plurality of substances such as a gas and a liquid or a plurality of liquids, it has been desired to develop an apparatus that can mix more stably and easily.

  The present invention has been made based on such a problem, and an object of the present invention is to provide a multifunctional mixing apparatus that can stably and easily mix a plurality of substances.

And a throttle valve.

  According to the present invention, since the mixing plug in which the mixing pores are formed, the adjusting plate in which the slit is formed in the peripheral portion, and the throttle valve in which the throttle pores are formed, the fluid flowing in from the inflow port is provided. By passing the mixed pores, slits, and throttle pores, the fluid can be sufficiently stirred and mixed. Therefore, a plurality of fluids can be mixed stably and easily, and the stability of the mixed fluid can be improved.

  Further, if the first adjustment plate and the second adjustment plate are provided as the adjustment plates, and the positions of the slits are shifted at least partially in the rotation direction around the center line, the fluid Stir mixing can be further promoted.

In this case, it is possible to further promote the stirring and mixing of the fluid in the mixing plug, the adjusting plate, and the throttle valve.

  In addition, if each mixed pore is made smaller on the outlet side than on the inlet side, it can diverge when fluid is collected and passed through each mixed pore. , The stirring and mixing of the fluid can be further promoted.

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

  FIG. 1 shows a cross-sectional configuration of a multifunction mixing device 1 according to an embodiment of the present invention. This multifunctional mixing device 1 mixes a plurality of fluids. The fluid may be liquid or gas, and can be preferably used when a gas is mixed with the liquid or when a liquid is mixed with the liquid. As a case where a gas is mixed with a liquid, for example, a case where carbonic acid gas is mixed and dissolved in water or warm water to produce carbonated water or a carbonated spring is preferable. This carbonated water or carbonated spring can be used for the human body such as medical treatment or beauty, and is also used in the fields of beverages, foods, sterilization, semiconductor industry, etc., agriculture / livestock industry, or environment. can do. In addition, examples of fluids to be mixed include medical gases such as oxygen, nitrogen, laughing gas, and sterilization gas, and chemicals such as pure water and hypochlorous acid.

  The multifunctional mixing device 1 includes, for example, a hollow mixing unit 10 in which a fluid inlet 11 is provided at one end and a fluid outlet 12 is provided at the other end. An internal flow path 13 through which a fluid flows is formed inside the mixing unit 10. The mixing unit 10 has, for example, a structure in which an inflow port 11 is provided at one end of a cylinder and an outflow port 12 is provided at the other end, and the internal flow path 13 in the direction perpendicular to the direction of fluid flow The cross-sectional shape is, for example, a circle.

  The inflow port 11 includes, for example, a first inflow channel 11A whose one end is communicated with the internal channel 13, and one or two or more ones whose one end communicates perpendicularly to the first inflow channel 11A. It is preferable to have the second inflow channel 11B. For example, when one or more additional fluids are mixed with the main fluid, the main fluid flows in from the first inflow channel 11A and the additional fluid flows in from the second inflow channel 11B. This is because mixing can be easily performed while adjusting the mixing amount. The channel cross-sectional areas of the first inflow channel 11 </ b> A and the second inflow channel 11 </ b> B are formed smaller than the channel cross-sectional area of the internal channel 13, for example. The outflow port 12 has, for example, an outflow channel 12 </ b> A whose one end communicates with the internal channel 13 and whose channel cross-sectional area is smaller than that of the internal channel 13.

  Inside the mixing unit 10, a mixing plug 20, at least one adjusting plate 30, and a throttle valve 40 are provided in this order so as to partition the internal flow path 13 from the inlet 11 to the outlet 12. ing. Inside the mixing unit 10, the central side of the internal flow path 13 flows to the central side of the internal flow path 13 on the inlet 11 side of the mixing plug 20, the adjustment plate 30, and the throttle valve 40. It is preferable that a detour plate 50 that detours the fluid to the peripheral side is provided.

  For example, it is preferable that a first connecting member 61 is provided between the bypass plate 50 and the mixing plug 20 to connect them together at the center. For example, it is preferable that a second connecting member 62 is provided between the mixing plug 20 and the adjustment plate 30 to connect them to each other at the center. For example, it is preferable that a third connecting member 63 that connects the adjusting plate 30 and the throttle valve 40 to each other at the center is disposed. For example, a hollow spacer 64 is provided between the mixing plug 20 and the inlet 11 and between the throttle valve 40 and the outlet 12 along the peripheral edge of the mixing plug 20 or the throttle valve 40. Preferably it is. This is to maintain these intervals and fix the position.

  2 shows the configuration of the mixing plug 20 taken out, (A) shows the configuration viewed from the inlet 11 side, (B) shows the configuration viewed from the outlet 12 side, C) represents a cross-sectional configuration along the line II. The mixing plug 20 has, for example, a plate shape in which a plurality of mixing pores 21 are provided, and the outer peripheral surface is disposed in contact with the inner side surface of the mixing unit 10, that is, the inner side surface of the internal flow path 13. . As a result, the fluid, for example, the main fluid and the added fluid flow through the mixing pores 21 to the outlet 12 and are stirred and mixed.

  Each mixing pore 21 is preferably formed, for example, such that the size of the outlet 12 side is smaller than the inlet 11 side. By collecting the fluid in each mixing pore 21 by enlarging the inflow port 11 side and reducing the outflow port 12 side, the fluid can diverge more greatly when passing through each mixing pore 21. This is because the stirring and mixing of the fluid can be further promoted. Each mixing pore 21 preferably has an inclined portion 21A that is inclined from the inlet 11 side toward the outlet 12 and gradually decreases in size.

  The size of each mixing pore 21 varies depending on the type of fluid to be mixed, the temperature, or the size of the apparatus. For example, the side of the inlet 11 is in the range of 0.2 mm to 15 mm, and the outlet 12 It is preferable that the side is within the range of 0.1 mm or more and 10 mm or less. This is because the stirring and mixing of the fluid can be further promoted. The number of mixed pores 21 varies depending on the size of the device, but is preferably about 12 to 30, for example.

  FIG. 3 shows the configuration of the adjustment plate 30 taken out, (A) represents the configuration viewed from the side, (B) represents the end surface configuration viewed from the inlet 11 side, (C) An end surface configuration viewed from the outflow port 12 side is shown, and (D) shows a cross-sectional configuration along the line II-II. The adjustment plate 30 is, for example, a plate shape in which a plurality of slits 31 are provided at the peripheral edge. The slits 31 are formed, for example, by cutting out a part of the outer peripheral surface inward, and six slits 31 are preferably provided at predetermined intervals in the circumferential direction along the outer peripheral surface. For example, the adjustment plate 30 is disposed such that the outer peripheral surface of a portion other than the slit 31 is in contact with the inner surface of the mixing unit 10, that is, the inner surface of the internal flow path 13. That is, it is preferable that a plurality of slits 31 are provided at intervals along the inner peripheral surface of the mixing unit 10.

  As a result, the fluid flows to the outlet 12 through the slit 31 provided in the peripheral portion, and is stirred and mixed. The width of the slit 31 varies depending on the type of fluid to be mixed, the temperature, or the size of the apparatus, but is preferably in the range of, for example, 5 mm to 20 mm, and more preferably in the range of 8 mm to 16 mm. preferable. This is because the stirring and mixing of the fluid can be further promoted.

  One adjustment plate 30 may be provided, but a plurality of adjustment plates 30 are preferably provided. This is because stirring and mixing can be further promoted. Moreover, although three or more adjustment plates 30 may be provided, it is preferable to use two adjustment plates. This is because even if the number of adjusting plates 30 is increased, the effect of stirring and mixing does not change much, and conversely, the flow rate decreases and the efficiency decreases. As the adjustment plate 30, for example, a first adjustment plate 30A and a second adjustment plate 30B are provided between the mixing plug 20 and the throttle valve 40 so as to partition the internal flow path 13 in order. preferable.

  The first adjustment plate 30A and the second adjustment plate 30B are, for example, rotational directions around the center line where the position of the slit 31 connects the center position of the first adjustment plate 30A and the center position of the second adjustment plate 30B. In addition, it is preferable that the displacement is at least partly. This is because the stirring and mixing of the fluid can be further promoted. Note that the first adjustment plate 30A and the second adjustment plate 30B may be configured such that the positions of the slits 31 are shifted at least in part by making the shapes of the slits 31 different. Therefore, it is preferable that the position of the slit 31 is shifted at least partially. This is because the fluid can be stirred and mixed in a balanced and stable manner.

  For example, it is preferable that an adjustment plate coupling member 32 is provided between the first adjustment plate 30 </ b> A and the second adjustment plate 30 </ b> B to couple them together at the center. This is to maintain these intervals. Further, the adjustment plate connecting member 32 has, for example, an outer peripheral cross-sectional area larger than that of the second connecting member 62 and the third connecting member 63, for example, a larger outer diameter. It is preferable that the area is narrowed. This is because by increasing the resistance between the first adjustment plate 30A and the second adjustment plate 30B, stirring and mixing of the fluid can be further promoted.

  4A and 4B show the configuration of the throttle valve 40, where FIG. 4A shows the configuration viewed from the inlet 11 side, FIG. 4B shows the configuration viewed from the outlet 12 side, C) represents a cross-sectional configuration along the line III-III. The throttle valve 40 has, for example, a plate shape in which a plurality of throttle pores 41 are provided, and is arranged with the outer peripheral surface in contact with the inner side surface of the mixing unit 10, that is, the inner side surface of the internal flow path 13. . As a result, the fluid flows through the throttle pore 41 to the outlet 12 and is stirred and mixed.

  For example, each throttle pore 41 may be smaller in size on the outlet 12 side than on the inlet 11 side, as with each mixed pore 21. Unlike the above, the size on the inlet 11 side and the size on the outlet 12 side may be the same. This is because the agitation and mixing of the fluid proceeds by passing through the mixing plug 20 and the adjusting plate 30, so there is no need to enlarge the inlet 11 side. The size of each throttle pore 41 varies depending on the type of fluid to be mixed, the temperature, or the size of the apparatus, but is preferably in the range of 0.1 mm to 10 mm, for example, 0.8 mm to 5 mm. It is more preferable if it is within the following range. This is because the stirring and mixing of the fluid can be further promoted. The number of throttle pores 41 varies depending on the size of the device, but is preferably about 12 to 30, for example.

  FIG. 5 is an enlarged view of the configuration of the bypass plate 50. The bypass plate 50 has, for example, a disk shape, and is preferably provided in the central portion of the internal flow path 13 so as to protrude from the mixing plug 20 toward the inlet 11 by the first connecting member 61. . The internal flow path 13 is narrowed to the outer peripheral side of the detour plate 50 by the detour plate 50, for example. For example, the bypass plate 50 is preferably formed to have a larger outer cross-sectional area than the first connecting member 61, for example, a larger outer diameter. The fluid that has flowed in from the inflow port 11 hits the detour plate 50, detours to the outer periphery of the detour plate 50, generates a vortex on the outlet 12 side of the detour plate 50, and promotes stirring and mixing of the fluid. It is.

  Moreover, it is preferable that the cross-sectional area of the outer periphery of the detour plate 50 is in the range of 80% to 100% of the flow path cross-sectional area of the first inflow flow path 11A. If it is too small, the effect of stirring and mixing the fluid is small, and if it is too large, the cross-sectional area of the internal flow path 13 is narrowed, the flow rate is reduced, and the efficiency is lowered. The outer diameter of the detour plate 50 varies depending on the size of the device, but is preferably about 12 mm to 25 mm, for example. The distance between the bypass plate 50 and the mixing plug 20 varies depending on the size of the apparatus, but is preferably about 8 mm to 15 mm, for example.

  FIG. 6 shows the flow of fluid in the multi-function mixing device 1. In the multi-function mixing device 1, fluid flows into the internal flow path 13 from the inlet 11. For example, when mixing one or two or more additional fluids with the main fluid, the main fluid flows in from the first inflow channel 11A, and one or more from the one or more second inflow channels 11B. Of added fluid individually. For example, a case where carbonated water or carbonated spring is produced will be described as an example. Water or warm water flows in from the first inflow channel 11A, and carbon dioxide gas flows in from the second inflow channel 11B. The fluid flowing in from the inlet 11 first strikes the bypass plate 50 of the mixing plug 20, bypasses the outer periphery of the bypass plate 50, generates a vortex on the outlet 12 side of the bypass plate 50, and is stirred and mixed. The For example, in the case of producing carbonated water, the size of carbon dioxide bubbles is reduced.

  Next, the fluid that has passed through the bypass plate 50 passes through the mixing pores 21 of the mixing plug 20, and thereby further stirred and mixed. For example, in the case of producing carbonated water, the size of carbon dioxide gas bubbles is further reduced. At that time, each mixed pore 21 has a large size on the inlet 11 side and a small size on the outlet 12 side, so that fluid is collected in each mixed pore 21, and It diverges greatly when passing through each mixing pore 21. In the case of producing carbonated water, more carbon dioxide gas passes through the mixed pores 21 and the size of carbon dioxide gas bubbles becomes smaller. Therefore, stirring and mixing of the fluid is further promoted.

  Subsequently, the fluid that has passed through the mixing pores 21 of the mixing plug 20 passes through the slits 31 of the adjustment plate 30, thereby being further stirred and mixed. For example, in the case of producing carbonated water, the size of carbon dioxide gas bubbles is further reduced. Specifically, it passes through the slit 31 of the first adjustment plate 30A, and then passes through the slit 31 of the second adjustment plate 30B. At that time, the first adjusting plate 30A and the second adjusting plate 30B are more at a part of the position of the slit 31 in the rotational direction, so that stirring and mixing of the fluid is further promoted. After that, the fluid that has passed through the slit 31 of the adjusting plate 30 passes through the throttle pore 41 of the throttle valve 40, thereby being further stirred and mixed. For example, in the case of producing carbonated water, the size of carbon dioxide gas bubbles is further reduced. The fluid that has passed through the throttle pore 41 of the throttle valve 40 flows out from the outlet 12.

  As described above, according to the present embodiment, the mixing plug 20 in which the mixing pores 21 are formed, the adjusting plate 30 in which the slits 31 are formed in the peripheral portion, and the throttle valve 40 in which the throttle pores 41 are formed are provided. Since it did in this way, the fluid can fully stir and mix by allowing the fluid which flowed in from the inflow port 11 to pass through the mixing pore 21, the slit 31, and the throttle pore 41. Therefore, a plurality of fluids can be mixed stably and easily, and the stability of the mixed fluid can be improved.

  Further, as the adjustment plate 30, a first adjustment plate 30A and a second adjustment plate 30B are provided, and the positions of the slits 31 are shifted at least partially in the rotation direction around the center line. In this case, stirring and mixing of the fluid can be further promoted.

  Further, on the side closer to the inlet 11 than the mixing plug 20, the adjusting plate 30, and the throttle valve 40, the detour that causes the fluid flowing in the central side of the internal flow path 13 to be detoured to the peripheral side on the central side of the internal flow path 13. If the plate 50 is provided, it is possible to further promote the stirring and mixing of the fluid in the mixing plug 20, the adjusting plate 30, and the throttle valve 40.

  In addition, if the size of the mixed pores 21 is made smaller on the outlet 12 side than the inlet 11 side, the mixed pores 21 diverge when collecting and passing the fluid through the mixed pores 21. Therefore, stirring and mixing of the fluid can be further promoted.

  The present invention has been described with reference to the embodiment. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, each component has been specifically described. However, not all the components may be provided, and other components may be provided. Each component may have other configurations.

  Furthermore, in the above-described embodiment, the mixing plug 20, at least one adjusting plate 30, and the throttle valve are arranged in the mixing unit 10 so as to sequentially partition the internal flow path 13 from the inlet 11 to the outlet 12. 40 is provided in this order, but the order of the mixing plug 20, the adjusting plate 30, and the throttle valve 40 may be different. In that case, it is preferable that the bypass plate 50 is disposed by the first connecting member 61 with respect to the one provided closest to the inflow port 11.

  In addition, in the above embodiment, the fluid that flows through the central side of the internal flow path 13 to the central side of the internal flow path 13 on the inlet 11 side of the mixing plug 20, the adjustment plate 30, and the throttle valve 40. However, in addition to the inlet 11 side or in place of the inlet 11, the mixing plug 20, the adjusting plate 30, and the throttle valve 40 are described. Alternatively, the detour plate 50 may be provided on the center side of the internal flow path 13 on the outlet 12 side.

  In the case of mixing a plurality of fluids, for example, it can be used when carbonated water or carbonated spring is produced by mixing carbon dioxide gas with water or warm water.
