  The mechanical device unit 1 in the illustrated example includes five tubular units 11 to 15 that are sequentially coupled by screws that can be tightened and loosened. The first tubular unit 11 is formed of a nonmagnetic material in order to suppress the entry of electromagnetic waves or the like. The first tubular unit 11 is divided by an annular partition wall 16 formed thereon, and sequentially has a hollow chamber 18 having an inflow side opening 17 at one end along the flow direction of the mixed fluid, and a second tubular unit. And a first recess 19 in which 12 is mounted. The hollow chamber 18 accommodates a strainer 20 that removes foreign matters by screwing the outlet portion 20a to the inner periphery of the annular partition wall 16. An inlet-side bushing 21 having an inflow hole 21 a for allowing the mixed fluid to be pumped to flow into the hollow chamber 18 is screwed into the inflow-side opening 17 of the hollow chamber 18. The mixed fluid that has flowed into the first tubular unit 11 from the pump 56 through the inlet hole 21a of the inlet-side bushing 21 flows from the outlet 20a to the first recess 19 side after foreign matter is removed by the strainer 20. It is supposed to be.

  The second tubular unit 12 is formed with convex portions 12a and 12b at both ends. One convex portion 12 a of the second tubular unit 12 is screwed into the first concave portion 19 of the first tubular unit 11. In addition, a projection 12c that is inserted into the outlet portion 20a of the strainer 20 is formed on the one convex portion 12a. The second tubular unit 12 has a conical surface shape in which the inflow hole 22 and the cross-sectional area of the flow path are successively narrowed along the flow direction of the mixed fluid from one convex portion 12a having the projection 12c to the other convex portion 12b. The flow path 23, the 1st nozzle 2 which accelerates | stimulates the flow velocity of the mixed fluid which distribute | circulates this, and the 1st rotor accommodating chamber 24 which accommodates the 1st rotor 4 are formed. The inflow hole 22 is formed in the protrusion 12 c and communicates with the outlet 20 a of the strainer 20.

  The conical surface channel 23 is formed by disposing a conical block 26 in a conical recess 25 formed by being recessed in the second tubular unit 12. The block 26 is appropriately connected to and supported by the inner peripheral surface of the conical recess 25. A wall 26 a that faces the inflow hole 22 is formed in the block 26. One end of the cone-shaped channel 23 having a large channel cross-sectional area communicates with the inflow hole 22, and the other channel having a narrow channel cross-sectional area is communicated with the first nozzle 2. The 1st nozzle 2 is provided between the cone-shaped planar flow path 23 and the 1st rotor accommodating chamber 24, and makes these communicate. The inner diameter of the first rotor storage chamber 24 is larger than the inner diameter of the first nozzle 2.

  The first rotor 4 is rotatably provided in the first rotor accommodating chamber 24 with the rotor surface 4 a facing the first nozzle 2. The first rotor 4 is also slidable in the flow direction of the mixed fluid in the first rotor accommodating chamber 24. A pair of first oblique slits 6 are formed on the outer periphery of the first rotor 4 at intervals of 180 °. These first oblique slits 6 are formed obliquely penetrating the first rotor 4 in the thickness direction, and the oblique directions thereof are set in the same direction along the circumferential direction of the first rotor 4.

  The mixed fluid that flows out from the outlet 20 a of the strainer 20 flows into the inlet 22 of the second tubular unit 12. The mixed fluid that has flowed into the inflow hole 22 collides with the wall surface 26 a of the block 26, whereby water and bubbles are crushed and miniaturized, and spread toward the cone surface channel 23 while spreading along the wall surface 26 a. Flowing. Water and bubbles of the mixed fluid further flow into the conical surface flow path 23 while being crushed by a shearing action around the block 26 connected to the conical surface flow path 23. As described above, since the cross-sectional area of the conical surface channel 23 is sequentially reduced along the flow direction of the mixed fluid, the fluid pressure of the mixed fluid is increased again and flows into the first nozzle 2. To do. By flowing through the first nozzle 2, the flow rate of the mixed fluid is accelerated and ejected toward the first rotor accommodating chamber 24.

  The mixed fluid ejected into the first rotor accommodating chamber 24 collides with the rotor surface 4a of the first rotor 4, whereby the water and bubbles are crushed and further refined and spread along the rotor surface 4a. Flows into the slit 6. The mixed fluid flows through the first oblique slit 6 to cause the first rotor 4 to generate a rotational force in one direction and rotate it. At the same time, when the first rotor 4 rotates, the mixed fluid that passes through the first oblique slit 6 is subjected to the action of shearing force, thereby flowing out from the first rotor 4 while flowing out as a swirling flow. In addition, water and bubbles are crushed by the first oblique slit 6. The flow of the mixed fluid is swirled by the first rotor 4 so that centrifugal force acts on the water that has been crushed and refined so that the water particles are once on the outside and the bubbles are on the inside. Separation action works. Further, the swirling flow of the one-way rotation becomes a spiral-like flow. The first rotor 4 slides in the first rotor accommodating chamber 24 according to the fluid pressure acting on the front and back, and balances the fluid pressure generated on both sides of the front and back to improve the fluidity of the mixed fluid. Yes.

  The third tubular unit 13 is formed with recesses 13a and 13b at both ends. The other convex portion 12 b of the second tubular unit 12 is screwed into one concave portion 13 a of the third tubular unit 13. The fourth tubular unit 14 is screwed into the other recess 13b. The third tubular unit 13 includes a swirling flow chamber 27 that maintains the swirling state of the mixed fluid that has flowed out of the first rotor 4 sequentially from one recessed portion 13a to the other recessed portion 13b along the flow direction of the mixed fluid. The second nozzle 3 for accelerating the flow velocity of the mixed fluid is formed. The swirling flow of the mixed fluid flowing out from the first rotor 4 passes through the swirling flow chamber 27 and flows into the second nozzle 3, and the flow velocity thereof is accelerated. The diameter of the second nozzle 3 is set larger than the diameter of the first nozzle 2. Considering that the flow rate of the mixed fluid gradually decreases due to pressure loss, etc., the nozzle size is set to be large in response to the decrease in flow rate so that the flow rate per unit time determined by (flow rate x nozzle size) is constant. Is done.

  The fourth tubular unit 14 has protrusions 14a and 14b at both ends. One convex portion 14 a of the fourth tubular unit 14 is screwed into the other concave portion 13 b of the third tubular unit 13. One end of the fifth tubular unit 15 is screwed to the other convex portion 14 b of the fourth tubular unit 14. The fourth tubular unit 14 includes a second rotor housing chamber 28 for housing the second rotor 5 and the mixing chamber 9 sequentially from the first convex portion 14a to the other convex portion 14b along the flow direction of the mixed fluid. A second concave curved wall portion 29 as a concave wall portion to be formed, and a jet outlet 30 that communicates the second concave curved wall portion 29 and the second rotor accommodating chamber 28 are formed. The inner diameter of the second rotor accommodating chamber 28 is larger than the inner diameter of the second nozzle 3.

  The second rotor 5 has a pair of second oblique slits 7 in the same direction as the first oblique slit 6, and is configured in the same manner as the first rotor 4. The outer diameter dimension of the second rotor 5 is set larger than the outer diameter dimension of the first rotor 4. If the rotational speed is the same, the peripheral speed of the outermost peripheral portion of the second rotor 5 having a large outer diameter is larger than that of the first rotor 4, so that even if the mixed fluid has a reduced flow velocity, the second oblique direction The mixed fluid that flows out from the slit 7 can flow out as a strong swirling flow. In addition, the size of the second oblique slit 7 is formed larger than the size of the first oblique slit 6, thereby making it possible to make the flow rate constant as in the setting of the nozzle diameter.

  The swirling flow of the mixed fluid ejected from the second nozzle 3 of the third tubular unit 13 to the second rotor accommodating chamber 28 collides with the rotor surface 5a of the second rotor 5, thereby crushing water and bubbles. Further miniaturization progresses and flows into the second oblique slit 7 while spreading along the rotor surface 5a. The mixed fluid flows through the second oblique slit 7 to cause the second rotor 5 to rotate in the same direction as that of the first rotor 4. At the same time, as the second rotor 5 rotates, the mixed fluid passing through the second oblique slit 7 is subjected to the action of shearing force, which further enhances the swirl flow and flows out from the second rotor 5 while flowing out. In doing so, water and bubbles are crushed by the second oblique slit 7.

  The mixed fluid is further refined in the fourth tubular unit 14, and further swirling is ensured by the action of an effective centrifugal force by the second rotor 5 having a diameter larger than that of the first rotor 4. The separation action of particles and bubbles is also strengthened. Further, the direction of the second oblique slit 7 is the same as that of the first oblique slit 6, and a spiral-like swirling flow is appropriately maintained. Even in the second rotor 5, the inside of the second rotor accommodating chamber 28 is slid according to the fluid pressure acting on the front and back, and the fluid pressure generated on both sides of the front and back is balanced to improve the fluidity of the mixed fluid. It has become. The mixed fluid that has passed through the second rotor 5 is spouted from the spout 30 as a swirling flow that has been refined and water particles are separated on the outside and bubbles are separated on the inside.

  The fifth tubular unit 15 has a storage chamber 32 that houses a wall body 31 having a first concave curved wall portion 8 as a concave wall portion, and one end is screwed to the other convex portion 14b of the fourth tubular unit 14. In addition, an outflow side opening 33 is formed at the other end, and an outlet side bushing 34 having an outflow hole 34 a is screwed into the opening 33. The wall body 31 is attached and fixed to the fifth tubular unit 15 with bolts 35. The first concave curved wall 8 is directed to the jet port 30 and defines the mixing chamber 9 as a spherical space between the second concave curved wall 29 and the second concave curved wall 29. The mixing chamber 9 is communicated with the outflow hole 34 a through a gap formed between the other convex portion 14 b of the fourth tubular unit 14 and the inner surface of the storage chamber 32 of the fifth tubular unit 15 and the wall body 31. The

  Since the mixing chamber 9 is a spherical space and the first concave curved wall portion 8 and the jet outlet 30 face each other, the swirling flow of the mixed fluid ejected from the jet outlet 30 flows into the first concave curved wall portion 8. Further miniaturization is promoted by collision, and the mixed fluid that has collided does not flow out of the mixing chamber 9 as it is, and is formed between the second concave curved wall 29 by the shape of the first concave curved wall 8. It is pushed back into the mixing chamber 9 which is a spherical space, is taken in and retained for a considerable residence time, and one direction of the mixed fluid sequentially ejected from the ejection port 30 during the residence in the mixing chamber 9 Since it is stirred repeatedly by the swirling flow of rotation and is agitated by this swirling flow of one-way rotation, the water and bubbles of the mixed fluid in which molecular clusters are refined are refined without causing aggregation. The state is maintained appropriately, and by this stirring action, the finely divided water particles and the bubbles that have been distributed in the separated state are mixed efficiently in the mixing chamber 9 at a stretch. Oxygen water in which oxygen-rich gas is dissolved is produced.

  The oxygen water generated in this way flows out from the mixing chamber 9 to the circulation system 55 toward the receiver tank 51 through the outflow hole 34a. The mixed fluid in which air bubbles are included in the water fed from the receiver tank 51 by the pump 56 has various sizes of water particles and air bubbles, and is agglomerated, the molecular bonding state is also different, and there is no homogeneity. However, by treating with the tubular units 11 to 15, it is refined to the nano order, the molecular bonding state is uniform, the aggregation state is eliminated, and the oxygen water can be made homogeneous and stable.

  In addition, a magnetizing unit 10 is provided which makes a magnetic force act on the water and bubbles of the mixed fluid to reduce the size. In the illustrated mechanical apparatus unit 1, the magnetization unit 10 is formed in an annular shape, and is provided outside the tubular units 11 to 15 so as to surround them. The magnetizing unit 10 has an arrangement in which the north poles of the upper and lower two magnets 41 face each other and the south poles of the two left and right magnets 41 face each other, and the tubular units 11 to 15 include four magnets 41 each having a magnetic plate 42 attached to the back. Is to be surrounded. A plurality of sets of the four magnets 41 are provided across the first to fifth tubular units 11 to 15 of the mechanical device unit 1. According to the arrangement in which the magnets 41 having the same polarity face each other, in the plane perpendicular to the flow direction of the mixed fluid, the circumferential direction of the tubular units 11 to 15 is approximately between the adjacent north and south poles. A strong magnetic field is generated along. The outer peripheral part of the tubular units 11-15 is an area | region where water particles concentrate and flow by the centrifugal action by a swirl flow, and it can accelerate | stimulate refinement | miniaturization of a mixed fluid also by this.

The diameter of the second nozzle 3 is set to be smaller than that of the second nozzle 3, and the oblique slits 6 and 7 are arranged along the flow direction of the mixed fluid so that the size of the first oblique slit 6 on the upstream side is set on the downstream side. Since the size of the second oblique slit 7 is set smaller than the size of the second oblique slit 7, the size of the nozzles 2, 3 and the oblique slits 6, 7 is set in the tubular units 11 to 15 to reduce the flow velocity due to the pressure loss of the mixed fluid. Therefore, the flow rate can be kept constant, the flow rate control can be stabilized, and the efficiency of the refinement process of the mixed fluid is improved.

The rotor 4 can also generate a strong centrifugal swirl flow, and when the speed is lowered, the rotor 4 has a large diameter and a difference in speed between the central portion and the outer peripheral portion. The swirling flow speed can be increased, and by setting the rotors 4 and 5 and setting the flow rate by adjusting the dimensions of the slits 6 and 7, the fluid mixture can be efficiently refined and the water particles and bubbles can be separated.

  Further, since the magnetizing unit 10 is provided surrounding the mixing chamber 9 from the nozzles 2 and 3 and the rotors 4 and 5 alternately provided along the flow direction of the mixed fluid, the magnetizing unit 10 and the tubular units 11 to 11 are provided. The apparatus can be miniaturized by parallel arrangement with 15, and the mechanical miniaturization process and the electromagnetic miniaturization process can be performed at the same time, so that the processing efficiency is improved as compared with the case of separate processing.

  In the circulation pipe 67, a magnetic application unit 90 is disposed on the downstream side of the mechanical device unit 1 along the flow direction of the mixed fluid. As shown in FIG. 4, the magnetic application unit 90 is provided with four upper, lower, left, and right permanent magnets 92 that surround the pipe 91 at an appropriate interval in the length direction outside the pipe 91 through which the mixed fluid flows. The permanent magnet 92 is surrounded by a rectangular tube-shaped magnetic body 93, and the magnetic body 93 is further surrounded by a rectangular tube-shaped magnetic ceramic tube 94. The magnetic application unit 90 uses the magnetic vibration generated between the permanent magnet 92 and the magnetic ceramic tube 94 to refine water and bubbles of the mixed fluid. Thereby, the fluid mixture flowing out from the mechanical device unit 1 can be further refined. By sequentially arranging the mechanization device section 1 on the upstream side and the magnetic application section 90 on the downstream side along the flow direction of the mixed fluid, water and bubbles are mechanically crushed in advance, It can be further miniaturized by the action, and oxygen water in which oxygen-rich gas is dissolved at a high concentration by efficient miniaturization can be generated.

  Next, the operation of the oxygen water production apparatus 50 according to this embodiment will be described. In the oxygen water production apparatus 50 according to the present embodiment, high concentration oxygen water is generated by performing batch processing in which the mixed fluid is circulated through the circulation system 55 as appropriate. First, the raw water on-off valve 59 is opened and closed to store water for one time in the receiver tank 51. At this time, the batch operation on-off valve 89 is opened, and the water storage on-off valve 82 and the pure water on-off valve 87 are closed. Next, the gas on-off valve 62 is opened and the oxygen concentrator 60 is started. Further, the pump 56 of the circulation system 55 is activated to start the circulation operation of the water in the receiver tank 51. When the oxygen concentrator 60 is activated, oxygen-rich gas is generated from the sucked air, and the generated oxygen-rich gas is supplied to the bubble diffusing means 53 via the gas supply pipe 61.

  The oxygen-rich gas can be ozonized by closing the bypass on-off valve 66 and starting the ozone generator 63 as necessary. Alternatively, the bypass on-off valve 66 may be opened so that a part of the oxygen-rich gas is circulated from the ozone generator 63.

  The bubble diffusing means 53 jets bubbles of oxygen-rich gas into the water. The ejected bubbles are sucked together with water from the starting end 55a of the circulation system 55 while being collected in the basket 54 and staying in the basket 54. At this time, since the bubble diffusing means 53 and one end of the circulation pipe 67 are disposed close to each other, and these are disposed in the basket 54, the circulatory system 55 can efficiently circulate oxygen-rich gas bubbles without waste. Can be sent to. Water and bubbles of the mixed fluid are pumped into the circulation system 55. The adjustment valve 72 of the replenishment system 70 may be controlled to replenish an appropriate amount of oxygen-rich gas from the gas supply system 52 to the mixed fluid that circulates in the circulation system 55. Thereby, the amount of oxygen-rich gas in the mixed fluid can be increased. The sensor 75 detects the operation state of the pump 56 during the circulation operation of the mixed fluid, thereby adjusting the pump operation and controlling the oxygen concentrator 50 and the regulating valve 72 to supply the oxygen-rich gas. Cavitation can be prevented by adjusting the amount.

  Water and bubbles of the mixed fluid pumped to the circulation system 55 are sequentially introduced into the mechanical unit 1 and the magnetic application unit 90 of the miniaturization means 57, and are thereby miniaturized by the above-described mechanical action and electromagnetic action. . The refined mixed fluid is returned from the circulation system 55 into the receiver tank 51. The returned mixed fluid is again flowed into the circulation system 55 together with the bubbles ejected from the bubble diffusing means 53, and is again refined. The mixed fluid is circulated through the circulation system 55 as appropriate together with the oxygen-rich gas continuously supplied from the bubble diffusing means 53 and the replenishment system 70, and repeatedly refined to increase the oxygen concentration. As a result, high-concentration oxygen water is produced.

  When the circulation operation for one time is completed, the batch operation on-off valve 89 is closed and the water storage on-off valve 82 is opened. Thereby, the produced oxygen water is pumped by the pump 56 and fed into the oxygen water tank 80 of the storage facility 77. At this time, if the pure water on-off valve 87 is also opened, the generated oxygen water is also circulated through the reverse osmosis membrane 86, whereby pure water is created and stored in the pure water tank 84.

  A demonstration test of the oxygen water production apparatus 50 according to this embodiment was performed. On April 17, 2007, 400 liters of tap water with a water temperature of 15.3 ° C. was treated with a treatment time of 60 minutes to produce oxygen water, which was inspected under atmospheric pressure. The dissolved oxygen in the produced oxygen water The amount was 49.1 mg / liter, and it was found that high concentration oxygen water could be produced. Thereafter, in order to confirm the progress of the produced oxygen water, it was inspected under atmospheric pressure on April 23, 2007. As a result, the dissolved oxygen amount in the oxygen water after about one week passed was 30.5 mg / It was found that oxygen water having a very stable property could be produced.

  In the oxygen water production apparatus 50 according to the present invention described above, when the water containing oxygen-rich gas bubbles is refined by the refinement means 57, the bubble aeration means 53 and the circulation system are placed in the basket 54. Since the start end 55a of 55 is disposed, oxygen can be efficiently mixed into water at the first stage of sending oxygen into water, and high-concentration oxygen water can be produced with high efficiency.

  Oxygen water of very fine molecular clusters can be generated by the miniaturization means 57 including the mechanical device unit 1 and the magnetic application unit 90. In the above-described embodiment, the case where the mechanical device unit 1 and the magnetic application unit 90 are provided as the miniaturization unit 57 has been described, but it is needless to say that only one of them may be configured. In addition, when the mechanical device unit 1 and the magnetic application unit 90 are provided side by side, the mechanical device unit 1 is disposed on the upstream side, and the magnetic application unit 90 is disposed on the downstream side, whereby efficient miniaturization processing can be performed. Since the circulatory system 55 is provided with the oxygen water storage facility 77 and the pure water preparation facility 78 is provided, not only oxygen water but also pure water can be produced.

  Since the sensor 75 for detecting the operation state of the pump 56 is provided, cavitation that can occur in the pump 56 that processes the gas-liquid mixed fluid can be appropriately monitored, and the safety of the operation of the apparatus can be improved. Since the replenishment system 70 for replenishing oxygen-rich gas is provided, the amount of oxygen mixed into the mixed fluid can be increased, and high-concentration oxygen water can be produced efficiently. Further, since the adjustment valve 72 is provided in the replenishment system 70, for example, the replenishment amount can be adjusted to a range that does not hinder the pump operation, and the safety of the apparatus operation can be improved.
