  However, the static fluid mixing device disclosed in Patent Document 1 is a diffusion / mixing flow path that diffuses and mixes the fluid flowing in from the inflow port on the center side in the radial direction toward the peripheral side, Compared to diffusion / mixing channels with high mixing / dispersion function because the flow channel structure that gathers and mixes the fluid flowing in from the peripheral side in the radial direction toward the center is formed in the same way. However, the collecting / mixing channel had a pressure loss comparable to that of the diffusion / mixing channel, although the number of dispersions was much smaller. Therefore, it has been desired to reduce the power consumption of the pressurizing pump that pressurizes and supplies the fluid to the static fluid mixing device, and to increase the flow rate (efficiency) of the processed fluid.

  Therefore, the present invention can reduce the pressure loss and reduce the power consumption of the pressurizing pump, and can increase the outflow amount (efficiency) of the mixed processed fluid. An object of the present invention is to provide a mold fluid mixing device.

That is, the corner 46 (36) of the recess 44 (34) is in contact with the center position of the recess 34 (44). Therefore, for example, when the case where the fluid R flows from the concave portion 34 side of the first element 30 to the concave portion 44 side of the second element 40 is considered, the fluid R is divided (distributed) into two flow paths. That is, the corner portion 46 of the second element 40 located at the center position of the recess 34 of the first element 30 functions as a flow dividing portion for dividing the fluid R. On the contrary, when the case where the fluid R flows from the second element 40 side to the first element 30 side is considered, the fluid R flowing from the two directions flows into one concave portion 34 to be joined. In this case, the corner portion 36 of the first element 30 positioned at the center position of the recess 44 of the second element 40 functions as a merging portion.

However, it flows while meandering from the inlet 50 side toward the outlet 51 side. At this time, the diameters of the opening surfaces of the recesses 35, 83, 84, 45 are formed to be smaller than one half of the diameter of the opening surface of the recesses 34, 44. The fluid R as the dispersed phase in the mixed fluid Rm is further refined by the shearing force received between them.

  In the mixing unit support 70, a number of mixing units 20 (10 in the present embodiment) are arranged in multiple layers so as to be symmetrical with respect to the left and right sides of the lower opening 77 communicating with the introduction port 11. Arranged in a stacked manner, an introduction path 13 is formed in the space between the multi-layer mixing units 20 on the left and right sides and extending straight from the lower opening 77 to the lower surface of the upper plate 71 of the mixing unit support 70. I am doing so. In addition, each inlet 50 of the plurality of mixing units 20 is communicated with the introduction path 13. In the mixing case 10, a lead-out path 14 is formed along the inner surfaces of the left and right wall portions 18, 18 facing the left and right outlets 51, 51 and the inner surface of the ceiling portion 15.

Yes.

  Plural (multiple) mixing units 20 are arranged in a superposed manner, and each inlet 50 is arranged along a virtual collinear line extending in the vertical direction, and the introduction path 13 is orthogonal to each inlet 50. By connecting, the introduction path 13 is formed in a straight shape in the vertical direction. Further, each outlet 51 is arranged along a virtual collinear line extending in the vertical direction, and the start end of the outlet path 14 is communicated with each outlet 51 in a state orthogonal to each outlet 51, that is, the starting end of the outlet path 14, that is, The portions communicating with the left and right side openings 75 and 76 are formed in a straight shape in the vertical direction.

  A plurality of mixing units 20 (two on the left and right in the present embodiment) extending in a radial direction (horizontal direction in the present embodiment) orthogonal to the axis of the introduction path 13 are arranged on the same plane and on the axis of the introduction path 13. A plurality of stages (in this embodiment, 10 stages on the left and right) are formed.

  The mixing unit 20 can be configured as a single unit by forming each part (component) from a synthetic resin such as an acrylic resin and bonding them together with an adhesive, or by using an alloy such as stainless steel. It is also possible to form an integral part by forming each part and integrally assembling these parts with screws.

  In the static fluid mixing apparatus M as the first embodiment configured as described above, for example, a plurality of different fluids R to be mixed are applied to the mixing case 10 through the inlet 11 by the discharge pump Pb which is a pressurizing pump. A plurality of different fluids R introduced by the mixing unit 20 disposed in the mixing case 10 are mixed together, and the mixed fluid Rm is led out of the mixing case 10 through the outlet 12. be able to.

  In the mixing unit 20, a plurality of different fluids R are caused to flow from the inlet 50 between the starting edge portions of the plate-like first element 30 and the second element 40 whose surfaces are opposed to each other. Until the fluid R flows out from the outlet 51 between the terminal edges 30 and 40, the fluid R is disposed between the concave portions 34 and 44 facing each other, between the concave portions 35 and 83, and between the concave portions 35 and 83. The mixed fluid Rm can be steadily generated by meandering and flowing between the recesses 84 and 45 while repeating joining and splitting. As a result, the generation efficiency of the mixed fluid Rm can be improved.

  At this time, the opening surfaces of the recesses 34, 44, the recesses 35, 83, and the recesses 84, 45 of the plurality (two sets in this embodiment) of the recess groups 32, 33, 42, 43 formed by being spaced apart are formed. The diameters of the recesses 35 and 83 and the recesses 84 and 45 on the outlet side are smaller than the recesses 34 and 44 on the inlet side. Therefore, a mixed fluid Rm in which the fluid R as the dispersed phase is refined is generated by the shearing force received when the fluid composed of the continuous phase and the dispersed phase flows while meandering between the recesses on the inlet side (upstream side). Is done. Then, with the interval from the outlet side (downstream side) to the recess groups 33 and 43 as the relay flow path 60, the flow of the generated mixed fluid is rectified while flowing through the relay flow path 60. Subsequently, the rectified mixed fluid flows while meandering between the recesses 35 and 83 and the recesses 84 and 45 on the outlet side (downstream side) in which the diameter of the opening surface of the recess is small. The fluid R as the dispersed phase is further refined by the shearing force received at this time.

  As described above, in the static fluid mixing apparatus M, since the flow of the fluid R is divided into the recess groups 32 and 42 and the recess groups 33 and 43 through the relay flow path 60 that is rectified, Pressure loss can be reduced. Therefore, it is possible to reduce the power consumption of the discharge pump Pb that pressurizes and supplies the fluid R to the static fluid mixing device M, and to increase the outflow amount (derived amount) of the processed mixed fluid Rm ( Efficiency). Then, in the continuous flow path from the inlet 11 to the outlet 12, the fluid as the dispersed phase has different shearing forces between the concave portions 35 and 83 and the concave portions 84 and 45 having different opening surface diameters. Since it is refined a plurality of times while receiving it, it is possible to perform the refinement generation to the micro level or the nano level steadily and efficiently.

  In addition, the inlets 50 of the plurality of mixing units 20 are communicated with the introduction path 13 that communicates with the inlet 11, and the outlets 51 of the plurality of mixing units 20 are communicated with the outlet path 14 that communicates with the outlet 12. Therefore, a plurality of fluid mixing processes are efficiently performed simultaneously by the plurality of mixing units 20. At this time, the number of the mixing units 20 can be appropriately communicated with the derivation / entry paths 14 and 13 by a desired number by appropriately setting the extension and extension of the introduction path 13 and the derivation path 14. Accordingly, by increasing or decreasing the number of the mixing units 20, the outflow amount (derived amount) of the mixed fluid can be appropriately set.

  Since the plurality of mixing units 20 are arranged in a multi-layered manner, and the starting ends of the introduction path 13 and the outlet path 14 are formed in a straight shape, a required number of mixing units 20 are provided in the mixing case 10. It can arrange | position compactly and can perform the fluid mixing process by each mixing unit 20 simultaneously in parallel efficiently. Therefore, an appropriate amount of the processed mixed fluid Rm can be generated by the appropriate number of the mixing units 20 arranged in a compact manner in the mixing case 10 and can be derived from the mixing case 10.

  A large number of mixing units 20 can be arranged in the mixing case 10 in a compact manner, and a mixed fluid can be generated simultaneously by each mixing unit 20. Therefore, a large amount of mixed fluid Rm can be generated efficiently.

  In addition, since the recesses 33 and 43 on the outlet 51 side (downstream side) are formed in two layers, the recesses 35 and 83 and the recesses 84 and 45 on the outlet 51 side (downstream side) formed in two layers. A large amount of the fluid R as the dispersed phase is refined by the shearing force received when flowing while meandering between each other. Therefore, micro-level or nano-level miniaturization can be efficiently performed.

It is formed by being spaced apart from the inlet 150 side toward the outlet 151 side.

  That is, the recess group 132 has a regular hexagonal opening shape on the inlet 150 side, which is the center side of the lower surface 131 of the first element 130 (viewed from the bottom), and a bottomed cylindrical recess 134 with no gap in the circumferential direction. A plurality of rows (three rows in the present embodiment) are arranged adjacent to each other in the radial direction, and the recesses 134 are opened downward. A large number of recesses 134 are formed in a so-called honeycomb shape. The recess group 133 connects the upper surface of the third element 137 formed in a ring plate shape to the outlet 151 side, which is the peripheral side of the lower surface 131 of the first element 130, in an overlapping state, and has an opening shape on the lower surface of the third element 137. (Bottom view) is a regular hexagonal bottomed cylindrical recess 135 that is vertically arranged adjacent to a plurality of rows (four in this embodiment) in the radial direction with no gap in the circumferential direction, and the recess 135 faces downward. Open. A large number of recesses 135 are formed in a so-called honeycomb shape. The diameter of the opening surface of the recess 135 is formed to be a small diameter that is not more than one-half of the diameter of the opening surface of the recess 134. The sum of the cylinder length of the recess 135 and the thickness of the third element 137 is formed to be the same as the cylinder length of the recess 134.

  Further, the concave group 142 includes a plurality of rows of radially concave hexagonal bottoms 144 having a regular hexagonal shape when viewed from the bottom on the inlet 150 side, which is the center side of the upper surface 141 of the second element 140, with no gaps in the circumferential direction. (In this embodiment, three rows) are provided adjacent to each other, and the concave portion 144 is opened upward. Many concave portions 144 are formed in a so-called honeycomb shape. The recess group 143 connects the lower surface of the fourth element 138 formed in a ring plate shape to the outlet 151 side, which is the peripheral side of the upper surface 141 of the second element 140, in an overlapped state, and has an opening shape on the upper surface of the fourth element 138 (Bottom view) is a regular hexagonal bottomed cylindrical concave portion 145 that protrudes adjacent to a plurality of rows (four rows in this embodiment) in the radial direction with no gap in the circumferential direction, and the concave portion 145 faces upward.

  The opposing recesses 134 and 144 are arranged at different positions so as to communicate with each other. That is, the corner portion 146 (136) of the concave portion 144 (134) is in contact with the central position of the concave portion 134 (144). Therefore, for example, when the case where the fluid R flows from the concave portion 134 side of the first element 130 to the concave portion 144 side of the second element 140 is considered, the fluid R is divided (distributed) into two flow paths. That is, the corner portion 146 of the second element 140 positioned at the center position of the concave portion 134 of the first element 130 functions as a diversion portion for diverting the fluid R. Conversely, when considering the case where the fluid R flows from the second element 140 side to the first element 130 side, the fluid R flowing from the two directions flows into one concave portion 134 and merges. In this case, the corner portion 136 of the first element 130 located at the center position of the concave portion 144 of the second element 140 functions as a merging portion.

  The opposing recesses 135 and 145 are arranged at different positions so as to communicate with each other in the same manner as the opposing recesses 134 and 144 described above. Reference numerals 137 and 147 denote corners of the recesses 135 and 145, respectively. As described above, a single meandering channel is formed between the recess groups 133 and 143 on the outlet 151 side of the first and second elements 130 and 140. The third (fourth) element 130 (140) can be integrally formed with the first (second) element 130 (140). Further, the recess group 132 (142) can be integrally formed with the first (second) element 130 (140). On the outlet 151 side of the first and second elements 130 and 140, as in the first embodiment, a split element in which concave and convex groups are formed on the upper and lower surfaces is disposed, and two layers of meandering channels are formed on the upper and lower sides. It can also be made.

  Constructed in this way, the fluid R repeatedly joins and diverts between the recesses 134, 144 and the recesses 135, 145 of the recess groups 132, 142 and the recess groups 133, 143 facing each other. It is made to flow while meandering toward the 151 side. Further, a flat relay channel 160 having a ring band shape is formed between the respective recess groups 132 and 142 and the recess groups 133 and 143 by the lower surface 131 of the first element 130 and the upper surface 141 of the second element 140. . The relay flow path 160 has a width corresponding to about three rows of the concave portions 134 and 144.

  Between the support plates 171 and 172 of the mixing unit support 170, a large number (10 in this embodiment) of the mixing units 120 are arranged in a multi-tiered manner around the lower opening 174 communicating with the inlet 111. In addition, an introduction path 113 that extends straight from the lower opening 174 to the lower surface of the upper support plate 171 is formed at the center of the multilayer mixing unit 120. In addition, each inlet 150 of the plurality of mixing units 120 is communicated with the introduction path 113. In the mixing case 110, a lead-out path 114 is formed along the inner peripheral surface of the peripheral wall portion 117 facing the outlet 151 and the inner surface of the ceiling portion 115. The outlets 151 of the plurality of mixing units 20 are communicated with the starting end side of the outlet path 114 via the peripheral end opening 173, while the outlet port 112 is connected with the terminal side of the outlet path 114.

  The disc-shaped mixing unit 120 extending in the radial direction (horizontal direction in the present embodiment) orthogonal to the axis of the introduction path 113 is divided into a plurality of stages along the axis of the introduction path 113 (in this embodiment, a large number of 10 stages on the left and right). Step).

  The mixing unit 120 may be configured integrally by forming each part (constituent member) with a synthetic resin such as an acrylic resin and integrally bonding them with an adhesive, or an alloy such as stainless steel. Each part can be formed by the above, and these can be integrally assembled by screwing together.

  In the static type fluid mixing apparatus M as the second embodiment configured as described above, between the inner peripheral edge portions of the first element 130 and the second element 140 which are formed in a ring plate shape and faced to face each other. The fluid R flowing in from a certain inlet 150 flows between the elements 130 and 140 while meandering radially in the radial direction thereof, and flows out from the outlet 151 between the outer peripheral edges. At this time, a plurality of recess groups 132, 133, 142, and 143 are divided into a ring shape with the inlet 150 as the center between the elements 130 and 140 with an interval from the inlet 150 side toward the outlet 151 side. Therefore, a large number of recesses 134, 135, 144, 145 can be arranged in each recess group 132, 133, 142, 143 and distributed in each recess group 132, 133, 142, 143. The fluid R as the phase is steadily miniaturized. Further, by arranging the mixing units 120 in multiple layers, a large amount of the refined mixed fluid Rm can be generated.

  In the mixing unit 120, the number of the recesses 135 and 145 in the recess groups 133 and 143 of the first and second elements 130 and 140 is gradually increased from the central portion side toward the peripheral portion side. The number of the concave portions 135 and 145 where the water flows merge increases toward the peripheral edge side, and is distributed (distributed) in proportion to the number. Therefore, in the meandering flow path, the number of times that the shearing force acts on the fluid R and is refined gradually increases along the flow direction of the fluid R (radial direction toward the peripheral edge side).
