  Embodiments of the present invention will be described below with reference to the drawings. That is, Sy2 shown in FIG. 1 is a water quality improvement system that improves the quality of the target water Ft in a closed water area in a sea area, a river, a lake, or the like. That is, the water quality improvement system Sy2 includes a floating body that is suspended on the surface of the target water Ft that is a water quality improvement target, and a gas-liquid mixing processing device C3 described later that is mounted on the floating body. The sucked target water Ft and the gas that improves the water quality are uniformly mixed to form mixed treated water, and the mixed treated water is reduced into the target water Ft. Hereinafter, a series of operations performed by the gas-liquid mixing apparatus C3 is referred to as a water quality improvement operation, and the water quality improvement operation includes an operation of repeating (circulating) the reduction. Examples of the gas for improving the water quality include oxygen, an oxygen mixed gas, nitrogen, and ozone.

  Specifically, BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) in sea areas can be reduced. Therefore, this water quality improvement system Sy2 can also be employed as an effective measure against red tide. In addition, by repeating (circulating) reducing the mixed treated water into the sea area and the like by mixing and treating a gas (for example, oxygen gas) effective for improving the water quality in a predetermined sea area, etc. It is also possible to improve the water quality in the sea area or the like so that the sea water or the like in the predetermined sea area can be converted to high-concentration oxygen water to promote the growth of seafood. Therefore, this water quality improvement system Sy2 can also be adopted as a seafood culture system. The seafood here is aquatic animals such as fish and shellfish, and the seafood aquaculture system is a system for aquaculture of aquatic animals.

  The seafood aquaculture system as one form of the water quality improvement system Sy2 will be described more specifically. As shown in FIG. 1, the seafood culture system floats a boat Bo with an outboard motor as a floating body on a water surface (water quality improvement target water surface) in a culture tank that is a tank of the target water Ft formed over a wide range. The boat Bo with an outboard motor is equipped with a gas-liquid mixing processing device C3. The gas-liquid mixing processing device C3 includes an engine pump N2 with a fluid mixer (hereinafter, also simply referred to as “a pump with a mixer N2”), and the pump N2 with a mixer is a fluid described later in the engine pump Pg. The mixer B1 or B2 is integrally attached.

  As shown in FIG. 1, the mixer-equipped pump N2 connects the introduction port 30 of the fluid mixer B1 or B2 to the discharge port 230 of the engine pump Pg via the introduction pipe 54, and introduces the fluid mixer B1 or B2. An outlet pipe 56 is connected to the outlet 31. The engine pump Pg includes an engine unit 200 such as a gasoline engine or a diesel engine, a suction pipe unit 210 linked to the engine unit 200, and a discharge unit 220 communicated to the suction unit 210. Reference numeral 212 denotes an intake filter. A fuel tank 240 is placed on the engine unit 200, and the liquid fuel stored in the fuel tank 240 is supplied to the engine unit 200 to drive the engine unit 200. The inhalation operation is performed to inhale the culture water, and the inhaled culture water is pumped to the discharge unit 220 and discharged from the discharge port 230.

  A first gas supply part Gf1 and a second gas supply part Gf2 for supplying gas are connected in parallel to the middle part of the introduction pipe 54 via a gas supply pipe Gp. In the middle of the gas supply pipe Gp, there is a gas that is positioned downstream of the three-way switching valve V9 and a three-way switching valve V9 that selectively switches the communication between the first gas supply unit Gf1 and the second gas supply unit Gf2. And a gas supply amount adjustment valve V10 for adjusting the supply amount. The first gas supply unit Gf1 and the second gas supply unit Gf2 can supply different types of gases, respectively, and in this embodiment, the nitrogen gas filled in the nitrogen gas cylinder can be supplied from the first gas supply unit Gf1. On the other hand, oxygen gas filled in the oxygen gas cylinder can be supplied from the second gas supply unit Gf2.

  The floating body only needs to be able to float on the aquaculture water surface by installing the gas-liquid mixing processing device C3, and freely floats on the water surface in the aquaculture tank like the boat Bo with an outboard motor of this embodiment. It is not restricted to what is possible, and depending on the case, a kite can be adopted as a floating body.

  In the seafood aquaculture system configured as described above, the gas-liquid mixing treatment device C3 is operated while running the boat Bo with an outboard motor as a floating body on the aquaculture water surface in the aquaculture tank, and the aquaculture water is supplied with high-concentration oxygen. I try to make it water.

  At this time, the gas-liquid mixing processing device C3 operates the engine unit 200 of the engine pump Pg to operate the suction unit 210 linked to the engine unit 200 so as to suck the culture water, Introducing into the communicating discharge unit 220 → discharge port 230 → introducing pipe 54, introducing oxygen gas from the second gas supply unit Gf2 into the introducing pipe 54, and introducing it into the fluid mixer B1 or B2 through the introducing port 30 Can be made.

  The culture water and oxygen gas introduced into the fluid mixer B1 or B2 in a pumped state are gas-liquid mixed by flowing in the fluid mixer B1 or B2, and are cultured from the outlet 31 through the outlet pipe 56. Reduction and further circulation through the fluid mixer B1 or B2 in the aquaculture water in Ft and repeated gas-liquid mixing treatment.

  As a result, even if the culture tank is formed over the sea surface over a wide area, the gas-liquid mixing treatment device C3 mounted on the boat Bo with an outboard motor can be quickly moved within the culture tank, and is formed over a wide area. Oxygen water in which oxygen gas is dissolved in the aquaculture tank's aquaculture water can be released uniformly, and the aquaculture water has a high concentration oxygen water whose DO value (dissolved oxygen amount) is 9 mg / L or more, for example. Can be made. In particular, in an aquaculture tank or fishing ground for oysters that are seafood, oxygen water is released while running the boat Bo with an outboard motor, so that the growth rate of oyster nymphs at the seedling raising time can be increased. Moreover, although it is a seaweed, it can also raise the growth rate of the laver seed in the seedling raising time by releasing oxygen water while running the boat Bo with an outboard motor in a nori culture tank or fishing ground.

  FIG. 2 is a conceptual explanatory diagram of a water quality improvement system Sy2 as another embodiment. Such a water quality improvement system Sy2 is a GPS (in which an outboard motor boat Bo having the same basic configuration as that of the outboard motor boat Bo having the mixer-equipped pump N2 mounted on the surface of the target water Ft. Through the Global Positioning System, the water quality of the target water Ft can be improved by running it unattended. That is, as shown in FIG. 2, the boat Bo with an outboard motor is provided with a self-propelled control device 500, and communicates with the GPS satellite 600 by the self-propelled control device 500 to acquire the current position information. Based on the acquired position information and the instruction information from the management facility 700 disposed on the land, the target water Ft is gas-liquid mixed while moving the boat Bo with an outboard motor along a virtual self-propelled route to be described later. Thus, the water quality of the target water Ft is improved.

  The self-propelled control device 500 controls the output of the outboard motor 550 and the mixer-equipped pump N2 based on detection information from various sensors provided in the boat Bo with the outboard motor in addition to the position information and the instruction information. (Including drive / stop control), self-running direction change control (steering control), and gas supply amount control to the fluid mixer B1 or B2. The various sensors here are sensors for obtaining information necessary for water quality improvement. For example, a sensor for detecting the water temperature, pH, DO value (Dissolved Oxygen) of the target water Ft, a boat Bo with an outboard motor, etc. It is a sensor which detects the movement state etc.

  Specifically, the self-running control device 500 includes a CPU (Central Processing Unit), a memory, a power supply, a wireless communication unit, an electronic compass, a GPS processing unit, a gyro sensor, an acceleration sensor, a position detection sensor, and the like. To do. The CPU functions as an arithmetic processing device and a control device, and a free-running control device according to a virtual free-running route generation program that generates a virtual free-running route virtually drawn on the surface of the target water Ft and other various programs. The overall operation within 500 is controlled. The CPU can realize various functions according to various programs. The memory can store programs used by the CPU, calculation parameters, and the like. The memory is a device for storing data, a storage medium, a recording device that records data on the storage medium, a reading device that reads data from the storage medium, and a deletion device that deletes data recorded on the storage medium, Etc. can be included. The power supply supplies power to each component such as a CPU constituting the self-running control device 500.

  The self-running control device 500 may include artificial intelligence (AI) that infers and / or determines which information should be integrated into the virtual self-running path. Artificial intelligence here refers to software and systems that mimic the water quality improvement work that the human brain is doing with computers, understand the natural language used by humans, make logical inferences, learn from experience A computer program or the like. For example, a probability-based or statistical-based approach can be used in connection with determination or inference. The reasoning is to explicitly train the classifier (s) before using the water quality improvement system Sy2, or at least to the movement operation, commands, commands, etc. of the boat Bo with an outboard motor while using the water quality improvement system Sy2. Can be based in part on implicit training.

  The management facility 700 is provided with a server 710 and a database (DB) 720 connected thereto, and the server 710 manages map information of the target water area, history information of water quality improvement work, and the like. The server 710 can communicate with the self-propelled control device 500 via a network 800 such as the Internet. The server 710 receives the water quality improvement work status from the self-propelled control device 500 (for example, the water quality improvement work position in the virtual self-propelled route of the boat Bo with an outboard motor and the water quality improvement work time at the position) in real time. Then, it is stored in the database 720 as history information of water quality improvement work. The virtual self-propelled path here can be set, for example, in a meandering shape, a spiral shape, or a lattice shape. The water quality improvement work position can be set continuously on the virtual self-propelled route, or can be set at a certain interval. That is, it is possible to continue the water quality improvement work or to perform the water quality improvement work only at a predetermined position.

  Next, the configuration of the mixed processing body and the mixing processing method that constitute a part of the gas-liquid mixing processing device C3 will be described, and then the configuration of the fluid mixer including the mixed processing body will be described.

[Description of Configuration of Mixed Processing Body as First Embodiment]
A1 shown in FIGS. 3 to 5 is a mixed processing body as the first embodiment. As shown in FIGS. 3 to 5, the mixed processing body A <b> 1 mixes the fluid F by being disposed in a fluid flow path R through which a plurality of different fluids F to be mixed flow. . The mixed processing body A1 splits the fluid F flowing in the fluid flow path R from the upstream side toward the downstream side in a bifurcated manner, and the fluid F split in a bifurcated manner by the flow dividing portion Df. It has a guide part Gu for guiding to the downstream side, and a narrow channel Rs that is provided in the guide part Gu and promotes the mixing process while guiding a part of the fluid F to the downstream side.

  The mixed processing body A1 includes a support piece 10 formed in a bolt shape, first and second washers 11 and 12, first and second elastic material pieces 13 and 14, and a plurality (25 in this embodiment). The narrow flow path forming piece 15 as the protruding portion, the spacers 16 as a plurality (24 in the present embodiment) of spacing holding pieces, and the nut 17 are provided.

  The support piece 10 has a rod-like book piece 10a formed in a circular cross section, a head part 10b formed by bulging the base end part of the book piece 10a in the radial direction, and a peripheral surface of a tip part of the book piece 10a. The formed male screw portion (not shown) is integrally formed of a metal material or a synthetic resin material.

  The first and second washers 11 and 12 are formed in a thin disk shape from a metal material or a synthetic resin material, and circular first and second insertion holes 11a through which the main piece 10a can be inserted in the center. , 12a. The first washer 11 is formed to have a diameter larger than the diameters of the respective arrangement holes 84 and 85 which are the same circular holes formed in the flow path forming case 20 of the fluid mixer B1 described later. The second washer 12 is formed with a diameter smaller than the diameter of each of the arrangement holes 84 and 85 described later.

  The first and second elastic material pieces 13 and 14 are made of an elastic material such as elastic rubber so as to have a thick disk shape having a diameter slightly smaller than the diameter of each of the arrangement holes 84 and 85 to be described later, and at the center. The circular first and second piece insertion holes 13a and 14a are formed through which the main piece 10a can be inserted. When the first and second elastic material pieces 13 and 14 are pressed in the axial direction, the first and second elastic material pieces 13 and 14 are elastically deformed in a bulging shape in the radial direction until the diameter becomes larger than the diameter of each arrangement hole. I have to.

  The narrow channel forming piece 15 is formed of a metal material or a synthetic resin material into a thin disk shape having a diameter slightly smaller than the diameter of each arrangement hole to be described later, and the main piece 10a can be inserted into the center portion. A circular forming piece insertion hole 15a is formed.

  The spacer 16 is formed of a metal material or a synthetic resin material into a thin disk shape having a diameter smaller than the outer diameter of the narrow channel forming piece 15 and a circular spacer through which the main piece 10a can be inserted at the center. The insertion hole 16a for use is formed. Here, the outer diameter of the spacer 16 is formed to be smaller than the outer diameter of the narrow channel forming piece 15, the opposing surfaces of the adjacent narrow channel forming pieces 15, 15, and both narrow channel forming pieces 15. , 15 and the outer peripheral surface of the spacer 16, a narrow channel Rs that opens in the circumferential direction and the outer side is formed flat on the outer periphery of the main piece 10 a.

  In other words, the narrow channel Rs can be appropriately set and adjusted by the outer diameter of the narrow channel forming pieces 15, 15, the outer diameter of the spacer 16, and the thickness of the spacer 16. In other words, the width and depth of the narrow channel Rs are set to the viscosity of the fluid F mixed through the narrow channel Rs, the degree of fineness of the dispersed phase of the mixed fluid F (mode diameter level to be nano-sized), and the like. Set accordingly. Here, “nano-ized” means to make the material fine at the nano level, and the nano level means a level where the dispersed phase is made fine to a particle size including 1 μm or less. The width of the narrow channel Rs is determined by the protruding width W1 of the narrow channel forming piece 15 described later. Further, the depth of the narrow channel Rs is determined by the thickness W2 of the spacer 16 described later. Therefore, the width and depth of the narrow channel Rs can be easily adjusted by appropriately replacing the desired narrow channel forming piece 15 and the spacer 16 with the main piece 10a.

  Specifically, when the viscosity of the fluid F is large (small), as shown in FIG. 3, the relative outer diameters of the outer diameters of the narrow flow path forming pieces 15 and 15 and the outer diameter of the spacer 16 are set. The protrusion width W1 of the narrow channel forming pieces 15, 15 that is the difference between the two is set to be large (small). Then, the thickness W2 of the spacer 16 is set to be large (small) so that the cross-sectional area of the flat narrow channel Rs becomes large (small). Further, when the dispersed phase of the fluid F is desired to be refined, the protrusion width W1 is set to be large in proportion to the degree of refinement. Then, the wall thickness W2 of the spacer 16 is set to be small and thin so that the narrow channel Rs is narrowed more flatly. Here, the protrusion width W1 can be appropriately set and adjusted in a range of 2 times or more, preferably 2 to 5 times the thickness W2.

  The narrow channel forming piece 15 can be formed as thin as possible. Further, the narrow channel forming piece 15 can be sharpened by making both ends of the tip edge portion into a double-edged tapered surface. In addition, every narrow channel forming piece 15 can be formed with a narrow protruding width W1 to increase the diameter of the inlet and outlet. By forming the narrow channel forming piece 15 in this way, the flow of the fluid F into each narrow channel Rs is facilitated through the tapered surface and the enlarged inlet, and each narrow channel is formed. The outflow of the fluid F from Rs can be smoothed. In particular, the narrow channel forming piece 15 formed in this way has a remarkable effect in facilitating fluid inflow and outflow to the narrowed channel Rs, and as a result, synergistically reduces pressure loss. And the effect of refining the dispersed phase can be improved.

  The nut 17 is formed of a metal material or a synthetic resin material into a thick short tube shape, is formed to have a smaller diameter than an arrangement hole described later, and is screwed to the male screw portion of the support piece 10 at the center portion. A wearable female screw portion (not shown) is formed.

  As described above, the mixed processing body A1 has a plurality of narrow flow paths in which the first washers 11 and the first elastic material pieces 13 are alternately arranged in the main piece 10a of the support 10 through the insertion holes. The forming piece 15 and the spacer 16, the second elastic material 14, and the second washer 12 are sequentially inserted, and the female screw portion of the nut 17 is screwed to the male screw portion of the support 10 so as to be integrated. doing.

  The narrow flow path forming pieces 15 and the spacers 16 arranged alternately are screwed in the tightening direction with nuts 17 and pressed in a pressure contact state in the axial direction of the main piece 10a, so that the flow dividing portions Df and the guide portions are formed. Retain Gu. That is, when the mixed processing body A1 is disposed in the fluid flow path R so that the axis is directed in a direction intersecting (preferably orthogonal) to the axial direction thereof, it faces the upstream side of the fluid flow path R. The arranged portion is formed as a diversion portion Df, and a pair of guide portions Gu for guiding the fluid F diverted by the diversion portion Df to the downstream side is formed. That is, the one side guide portion Gu and the other side guide portion Gu are formed in a branched state. At the same time, each guide portion Gu has a narrow channel Rs formed in a flat shape extending from the upstream side to the downstream side of the fluid channel R, and a plurality (in this embodiment) in the axial direction of the main piece 10a. Then, a large number of narrow channels Rs are formed in parallel. Further, by removing the female threaded portion of the nut 17 from the male threaded portion of the support 10 by unscrewing, the narrow channel forming pieces 15 and the spacers 16 can be easily removed from the main piece 10a, and they are desired. It can be replaced with one of the shape. That is, the maintenance of the mixed processing body A1 and the adjustment of the flatness of the narrow channel Rs can be easily performed.

  The mixed processing body A1 configured as described above has its axis lined in a direction intersecting (preferably orthogonal) to the axial direction in the fluid flow path R through which a plurality of different fluids F to be mixed flows. Deploy. Then, the fluid F flowing in the fluid flow path R collides with the flow dividing portion Df of the mixed processing body A1 and is bifurcated (in a two-divided state) along the peripheral surface of the guide portion Gu of the mixed processing body A1. The flow is divided and merged behind the mixed processing body A1. At this time, the fluid F branched along the peripheral surface of the guide portion Gu flows into a large number of narrow flow paths Rs formed in parallel in the axial direction of the support piece 10 and further splits into a multi-divided state. Is done. The fluid F that has flowed and passed through each narrow channel Rs generates a vortex or turbulent flow behind the mixed processing body A1, and the dispersed phase of the fluid F is refined by the vortex or turbulent flow.

  The fluid F flows out from the relatively wide fluid flow path R into the narrow (narrow) narrow flow path Rs and flows out from the narrow flow path Rs to the fluid flow path R. Therefore, a shearing force is generated due to a speed difference between the fluids F. As a result, the dispersed phase of the fluid F is also refined by shearing force. Further, the passage flow velocity of the fluid F passing through the narrow channel Rs is increased as the narrow channel Rs is narrowed, and the above-described miniaturization efficiency is improved. Here, the mixed processing body A1 is arranged in the fluid flow path R so that the fluid F is bifurcated into a bilaterally symmetrical shape (divided into two divided states), and the fluid F passes through a large number of narrow flow paths Rs. Therefore, it is possible to reduce the overall flow loss, that is, the pressure loss.

A straight cylindrical decorative case 21 arranged in a double cylinder shape, an upstream connection piece 22 communicating with the upstream side of both cases 20, 21, and a downstream side communicating with the downstream side of both cases 20, 21 A connecting piece 23, an upstream fixing piece 24 that is screwed to the upstream end of the decorative case 21 to fix the upstream connecting piece 22, and a downstream connecting piece that is screwed to the downstream end of the decorative case 21 And a downstream side fixing piece 25 for fixing 23.

  The flow path forming case 20 includes an introduction port 30 through which the fluid F is introduced, a fluid flow path R through which the fluid F introduced from the introduction port 30 flows, and a discharge port 31 through which the fluid F is derived from the fluid flow path R. And a plurality (five in this embodiment) of mixed processing bodies A1 are arranged in the flow path forming case 20.

  More specifically, the mixed processing body A1 is a first and second virtual line formed in a pair of spirals (double spirals) drawn on the peripheral wall of the flow path forming case 20 in the axial direction. Between K1 and K2, it arranges in the flow passage formation case 20 so as to intersect with the axis of the flow passage formation case 20 (orthogonal in this embodiment), and the first and second virtual lines K1, K2 5 pieces are arranged along the stretching direction and at regular intervals.

  The pair of first and second imaginary lines K1, K2 draws two straight lines in a state where the flow path forming case 20 is expanded in a flat plate shape, as shown in the development explanatory view of FIG. These straight lines are arranged in parallel so as to face each other 180 degrees around the axis of the flow path forming case 20. In the position on the first imaginary line K1, the first to fifth arrangement holes 34a to 38a, which are a group of the arrangement holes 84 described above, are formed with a certain interval from the upstream side to the downstream side. At the same time, the first disposition hole 34b to the fifth disposition hole 38b, which are a group of the disposition holes 85, are spaced apart from the upstream side to the downstream side at a position on the second virtual line K2. Forming.

  Then, when the flow path forming case 20 developed in a flat plate shape is bent into an original cylindrical shape, the pair of first and second virtual lines K1, K2 are formed in a double spiral shape, They are arranged at positions 180 degrees symmetrical with respect to the axis of the flow path forming case 20. Further, the pair of first arrangement holes 34a and 34b to the fifth arrangement holes 38a and 38b arranged on the pair of first and second virtual lines K1 and K2 intersect the axis of the flow path forming case 20, respectively. It is located on a virtual coplanar plane (orthogonal in the present embodiment) and symmetrical with respect to the axis of the flow path forming case 20 at 180 degrees (on the same diameter of the flow path forming case 20). .

  Therefore, the first arrangement holes 34a and 34b to the fifth arrangement holes 38a and 38b are respectively inserted through the tip of the mixed processing body A1 from the one arrangement hole side, and are arranged to face each other at a point-symmetrical position. By projecting the tip portion from the arrangement hole, each mixed processing body A1 can be arranged in a transverse penetrating manner at a position on the same diameter in the flow path forming case 20. The five mixed processing bodies A1 have the base end portion and the tip end portion disposed on the first and second virtual lines K1 and K2, respectively, and are spaced along the axis of the flow path forming case 20. And are arranged at twisted positions relative to each other. That is, when viewed from the axial direction of the fluid flow path R (upstream side or downstream side of the flow path forming case 20), the axes of the five mixed processing bodies A1 are orthogonal to the axis of the flow path forming case 20, Centering on the shaft core, the flow path forming case 20 is sequentially arranged at a position biased at a constant angle in the circumferential direction.

  In the pair of first arrangement holes 34a, 34b to fifth arrangement holes 38a, 38b, the mixed processing bodies A1 are respectively inserted and attached from the front end side of the support body 10 so as to be freely inserted and removed. At this time, the mixed processing body A1 is in a state where the nut 17 is relaxed in advance, and the first and second elastic material pieces 13 and 14 are not bulged and deformed in the radial direction. It inserts in 34a-the 5th arrangement | positioning hole 38a. Then, the mixed processing body A1 is disposed in a state of penetrating and traversing at a position (diameter position) passing through the center of the circular axial cross section of the fluid flow path R formed in the flow path forming case 20. The first washer 11 is locked from the outside in the first arrangement hole 34a to the fifth arrangement hole 38a on the inserted side. At the same time, the nut 17 is exposed outward from the flow path forming case 20 from the other first arrangement hole 34b to the fifth arrangement hole 38b. When the exposed nut 17 is tightened, the first and second elastic material pieces 13 and 14 are pressed in the axial direction thereof, and the elastic material pieces 13 and 14 are bulged and deformed in the radial direction. As a result, the outer peripheral surfaces of the elastic material pieces 13 and 14 are pressed against the inner peripheral surfaces of the pair of first arrangement holes 34a and 34b to the fifth arrangement holes 38a and 38b (surface contact in the pressed state). The sealing effect by each elastic material piece 13 and 14 is produced. Then, the mixed processing body A1 is attached in a fixed state in the flow path forming case 20.

  In addition, a water-stopping material 40 as a sealing material is caulked (filled) around the head portion 10b and the nut 17 projecting outward from the flow path forming case 20 in the radial direction, and the respective arrangement holes 34a. ˜38b is closed from the outside. Further, the water stop material 40 prevents the fluid F flowing in the fluid flow path R from leaking or flowing out of the flow path forming case 20 through the respective arrangement holes 34 a to 38 b.

  On the inner peripheral surface of the flow path forming case 20, upper and downstream groove portions 41, 42 are formed at the upstream end portion and the downstream end portion, respectively, and an O-ring shape as a sealing material is formed in each groove portion 41, 42. Gaskets 43 and 44 are inserted and arranged.

  The decorative case 21 covers the head 10b and the nut 17 of the mixed processing body A1 projecting outward in the radial direction from the flow path forming case 20, and the sliding of the mixed processing body A1 in the axial direction from the outside. It is formed with an inner diameter that can be regulated (prevented from coming off). The decorative case 21 is formed in the same cylinder length as the flow path forming case 20.

  As shown in FIGS. 35 to 37, the upstream connection piece 22 protrudes from a cylindrical insertion portion 50 formed to be able to be inserted into the introduction port 30 of the flow path forming case 20, and to an outer peripheral surface end portion of the insertion portion 50. The flange 51 formed in a shape and the cylindrical connection 52 protruding coaxially with the fitting portion 50 on the outer surface of the flange 51 are integrally formed of a synthetic resin material. The fitting portion 50 has an outer diameter that is substantially the same as the inner diameter of the flow path forming case 20, and is closely attached to the inner peripheral surface of the flow path forming case 20 via the gasket 43 so that it can be inserted and removed freely. The flange portion 51 is in contact with the end surface of the flow path forming case 20 to limit the insertion width of the insertion portion 50 to be inserted into the flow path forming case 20. The connecting portion 52 has a tapered shape in which the inner peripheral surface gradually increases in diameter from the proximal end side to the distal end side, and a connecting female screw portion 53 is formed on the inner peripheral surface.

  The downstream connection piece 23 is attached to the outlet 31 of the flow path forming case 20, but is formed in the same shape as the upstream connection piece 22 and can be shared. Therefore, the downstream connection piece 23 can be attached to the inlet 30 of the flow path forming case 20, and the upstream connection piece 22 can be attached to the outlet hole 31 of the flow path forming case 20. Reference numeral 54 denotes an introduction pipe, which has an introduction-side male screw portion 55 at the end. Reference numeral 56 denotes a lead-out pipe, and a lead-out side male screw part 57 is formed at the end. Both the male screw portions 55 and 57 can be detachably screwed to the connecting female screw portion 53.

  The upstream side fixing piece 24 and the downstream side fixing piece 25 are formed in the same shape as each other and can be shared. The upper / downstream connection pieces 22, 23 can be fixed to the flow path forming case 20 via the upper / downstream fixing pieces 24, 25. These fixing pieces 24, 25 are cylindrical fixing portions 60, 60 and ring plate-like engaging portions 61, 61 extending inwardly from the outer peripheral edge of each of the fixing portions 60, 60. , Formed from. The fixing portion 60 has a fixing female screw portion 62 formed on the inner peripheral surface thereof, and is fitted on the end portion of the flow path forming case 20 and is fixed on the upstream side formed on the end portion of the outer peripheral surface of the decorative case 21. The fixing female screw portion 62 is screwed onto the male screw portion 63 (or the downstream fixing male screw portion 64), so that it can be fixed to the decorative case 21. The engaging portion 61 is externally fitted to the connecting portion 52 and tightens the fixing portion 60 so that its inner surface engages with the outer surface of the flange portion 51 in a contact state.

  And the engaging part 61 can clamp the collar part 51 between the end surfaces of the flow path formation case 20. As a result, the connection pieces 22 and 23 can be fixed in the connected state to the introduction / exit holes 30 and 31 of the flow path forming case 20 via the fixing pieces 24 and 25. Further, the connection pieces 22 and 23 can be removed from the flow path forming case 20 by unscrewing the fixing pieces 24 and 25 in the opposite direction.

  As described above, the fluid flow path R formed in the flow path forming case 20 has a circular cross-sectional shape that matches the cross-sectional shape orthogonal to the axis of the flow path forming case 20. The single mixed processing body A1 is disposed in the fluid flow path R along the diameter of the axial cross section. Therefore, on both sides of the mixed processing body A1, the bypass flow path is symmetrized in a geometrically equivalent form so that the fluid F is divided into two divided states along the bypass flow path and mixed. A part of the fluid F is divided into a multi-divided state in the narrow flow paths Rs formed in parallel in the axial direction of the fluid A1, and the fluid F is integrally joined behind the mixed processing body A1. The five mixed processing bodies A1 are arranged at twisted positions along the first and second virtual lines K1 and K2 arranged in a double spiral shape. Therefore, the fluid F is sequentially led out as a spiral flow while being divided into five mixed processing bodies A1. As a result, the flow loss (pressure loss) of the fluid F is less likely to occur, the flow velocity of the fluid F passing through both sides of the mixed processing body A1 is increased, and the refinement efficiency of the dispersed phase is improved.

Five) mixed processing bodies A2 are arranged.

  More specifically, the mixed processing body A2 extends along the extending direction of the first and second virtual lines K1, K2 drawn in a double spiral shape on the peripheral wall of the flow path forming case 20 in the axial direction. In addition, five pairs of two pairs are arranged at regular intervals. That is, the first arrangement hole 34a to the fifth arrangement hole 38a formed along the first virtual line K1, and the first arrangement hole 34b to the fifth arrangement formed along the second virtual line K2. The base end portion of the mixed processing body A2 is attached to each hole 38b, and each distal end portion is disposed in the vicinity of the axis of the flow path forming case 20. A female screw portion (not shown) for screwing the mounting male screw portion 70d is formed on the inner peripheral surface of each of the arrangement holes 34a to 38b. In each of the arrangement holes 34a to 38b, the front end of the mixed processing body A2 is inserted from the outside to the inside of the flow path forming case 20, and a mounting male screw 70d is screwed into each female screw. At the same time, two pairs of the mixed processing bodies A2 are supported by the flow path forming case 20 in pairs.

Locked. The pair of mixed processing bodies A2 and A2 whose axial lines face each other in the radial direction of the flow path forming case 20 are brought into surface contact with the ceiling portion 71a of the fitting covering piece 71 in a pressed state. That is, the pair of mixed processing bodies A2 and A2 are arranged in a straight shape and a transverse penetrating shape at a diameter position in the flow path forming case 20. The five pairs of the mixed processing bodies A1 are arranged at twisted positions along the first and second virtual lines K1 and K2. Around the head portion 70b with a concave portion for operation protruding outward from the flow path forming case 20 in the radial direction, a water stop material 40 is caulked (filled), and the respective arrangement holes 34a to 38b are formed outward. The fluid F flowing in the fluid flow path R is prevented from leaking out or flowing out of the flow path forming case 20 through the arrangement holes 34a to 38b.

  The upstream swirl flow forming body 32 and the downstream swirl flow forming body 33 are similarly formed of synthetic resin, and swirl flow forming blades 32b and 33b are provided on the outer peripheral surfaces of the support shafts 32a and 33a formed in a straight rod shape.

It is fixed in a pinched state. Further, the downstream swirl flow forming body 33 is formed between the distal end surface of the fitting portion 50 of the downstream connection piece 23 and the pair of mixed processing bodies A2 and A2 arranged on the most downstream side in the flow path forming case 20. It is fixed in a sandwiched state.

  In the fluid mixer B2 configured as described above, the introduced fluid F becomes a swirl flow by the upstream swirl flow forming body 32 and acts on the five pairs of the mixed processing bodies A2 and A2, and the downstream swirl flow forming body. It is derived | led-out by 33, ensuring a swirling flow. At this time, since the fluid F acts on each pair of the mixed processing bodies A2 and A2 as a swirling flow having a larger flow velocity on the outer peripheral side than on the center side, the flow to the narrow channel Rs in each mixed processing body A2. A part of the fluid F flows smoothly. As a result, miniaturization of the dispersed phase of the fluid F and uniform mixing of the dispersed phase and the continuous phase are steadily achieved.
