Suppressing force in the rotation direction when the revolving force is approached by the same-polar magnet on which the repulsive force acts, or depressing in the rotational direction when the first and second magnets are opposite to each other by the opposite-polarity magnet on which the opposing sides act on each other The force can be dispersed in the force, and their rotation deterring force can be reduced.

  That is, the longitudinal directions of the first and second magnets provided on the fixed portion side and the rotating portion side are inclined at different angles, for example, the longitudinal directions of the first and second magnets are taken as lines.

In the case of being parallel to the axial direction, the first and second magnets face each other with respect to the treatment liquid flowing obliquely, so the action of the magnetic force is instantaneous. 1. When the longitudinal direction of the second magnet is tilted, the intersections with the first and second magnets tilted in the longitudinal direction are continuously moved and continuously with respect to the treatment liquid flowing obliquely. Magnetic force will act on this. As a result, the treatment liquid in the gap formed between the fixed part and the rotating part increases the number of microbubbles and the amount of dissolved gas, and the electromagnetic action by the first magnet and the second magnet. The microbubbles in the treatment liquid that have flowed into the gap due to the synergistic action are more effectively divided and subdivided to generate more microbubbles, and the gas components in the microbubbles Is further dissolved in the processing solution.

First, as a precondition in FIGS. 7 to 9, a force “1” is exhibited when the first and second magnets 9 and 10 face each other. At the midpoint, the magnetic force is “0 (zero)”. There shall be no influence of other magnets. The same idea applies to the circumferential direction and the radial direction of the fixed portion 2 and the rotating portion 3.

In the uppermost stage of FIG. 7, the first magnet 9 is arranged at the positions “0”, “2”, “4”, “6”, “8”, and the second magnet 10 is “0”, “2. 5 ”,“ 5 ”, and“ 7.5 ”.

  FIG. 9 shows a force of “1” when the first and second magnets 9 and 10 face each other as in FIG. 7, and the magnetic force is “0 (zero)” at the intermediate point. The magnet was not affected. However, in relation to the distance, FIG. 7 shows an inverse proportion to the distance, but FIG. 9 shows a calculation result assuming that the magnetic force is inversely proportional to the square of the distance. α was the same as in FIG. 7 and was calculated only for the case of “−α”. Further, although the calculation is performed as a force applied to the fixed portion 2, a reaction force of this force is applied to the rotating portion 3. “F” means the total force, “+” means that a force in the rotational direction acts on the fixed portion 2, and “−” means that a force opposite to the rotational direction, that is, an inhibitory force acts on the fixed portion 2. To do. Therefore, as a counteraction, the rotation unit 3 is subjected to a force (inhibition force) opposite to the rotation direction and a force in the rotation direction.

  FIG. 10A shows the magnet arrangement of the first magnet 9 of the first-stage annular block body 8 and the magnet arrangement of the second magnet 10 of the rotating unit 3, and the first is based on the calculation result of FIG. The force applied to the magnet 9 is illustrated. A total force of “2” is generated in the first magnet 9 of the first-stage annular block body 8, and a rotation inhibition force of “2” is generated in the rotating portion 3 as a reaction. FIG. 10B shows a force relationship acting in the rotation direction of the fixed portion 2 and the rotating portion 3 by the magnet arrangement of the first magnet 9 of the first-stage annular block body 8, and A, -A, B, -B. Is a force acting on the rotating portion 3, and X, -X, Y, -Y are forces acting on the fixed portion 2, and indicate that the resultant force applied to the shaft is balanced. That is, when the first and second magnets 9 and 10 are equally arranged as in the present embodiment, the number of pairs of the first and second magnets 9 and 10 facing each other at the same time is, for example, one set. By avoiding the above, it is possible to easily maintain the balance of the resultant force applied to the rotating shaft 3a, which is particularly effective in a configuration having a small number of stages.

  In FIG. 7, five first magnets 9 are provided on the inner peripheral surface 8 a side of the annular block body 8 of the fixed portion 2, and four second magnets 10 are provided on the outer peripheral surface 3 b side of the rotating portion 3. In this case, the rotational force of the rotating unit 3 has been described. 8 and 9, the force received by the fixed portion 2 is calculated based on the assumption that the magnetic force is inversely proportional to the square of the distance. A rotational force is generated as a reaction of the force applied to the fixed portion 2 on the rotating portion 3. . In the above-described embodiment, the maximum rotational force calculated under such conditions generates a force of “4.00” in the fixed portion 2, and “-4.00” (rotation inhibiting force) as a reaction in the rotating portion 3. Will occur.

  For example, as a comparative example, eight first magnets 9 provided on the inner peripheral surface 8a side of the annular block body 8 of the fixed portion 2 arranged so that all the magnets face each other, on the outer peripheral surface 3b side of the rotating portion 3. The maximum rotational force is “48” when eight second magnets 10 are provided and the six-stage annular block body 8 is provided inside the cylindrical case 7. In addition, when either one of the first and second magnets 9 and 10 is removed two by two and the first and second magnets 9 and 10 facing each other are 8 and 6 respectively, the maximum is 6 The rotational force is “36” (see FIG. 8A).

  Further, in the above magnet arrangement, two of the second magnets 10 provided on the outer peripheral surface 3b side of the rotating portion 3 are removed to make six, and the second magnet 10 provided on the inner peripheral surface 8a side of the annular block body 8 of the fixed portion 2 is provided. The maximum rotational force is 36 when eight magnets 9 are provided and the six-stage annular block body 8 is provided inside the cylindrical case 7 (see FIG. 8).

  FIG. 10A shows the state of the first stage of the annular block body 8 having the magnet arrangement shown in FIG. 8B. The rotational force “2” is applied to the first magnet 9 of the fixed portion 2. It can be seen that the power of all is applied. As a reaction, the rotation inhibiting force of “−2” acts on the second magnet 10 of the rotating body 3. Further, as shown in FIG. 10B, the balance of force when the first and second magnets 9 and 10 are considered in the radial cross section of the fixed portion 2 and the rotating portion 3 is a magnet opposed on the circumference. Become two sets each, and balance as a whole (force is “0 (zero)”).

  Further, in the magnet arrangement in which the annular block body 8 has a plurality of stages, a phase is provided in the arrangement of the first magnets 9 provided on the inner peripheral surface 8a of the annular block body 8 at each stage. The phase may be provided in the arrangement of the first magnet 9 provided on the inner peripheral surface 8a of the annular block body 8, or the phase may be provided in the arrangement of the second magnet 10 provided on the outer peripheral surface 3b of the rotating portion 3. However, it is also possible to provide a phase in the arrangement of both the first and second magnets 9 and 10.

  The phase of the first magnet 9 provided on the inner peripheral surface 8a of the annular block body 8 of each step or the phase of the second magnet 10 provided on the outer peripheral surface 3b of the rotating part 3 is determined from the number of arrangements on the circumference and the number of steps. The frequency is such that the whole is nearly equal. The phase effect can be maximized by appropriately selecting the combination of the number of arrangements and the number of stages on the circumference. The phase direction may be either advanced or delayed depending on the purpose.

  When the first and second magnets 9 and 10 are arranged in the same number, the positions can be shifted instead of facing each other.

  Thereby, regardless of the total number of magnets per stage, it is possible to reduce the number of magnets that face each other simultaneously and increase the attractive force and the repulsive force to one pair or two pairs.

  Further, even in multi-stage axial directions, the magnet arrangement facing each other can be suppressed to one stage or two stages.

  In this embodiment, the magnet arrangement is such that eight rows of second magnets 10 are arranged on the outer peripheral surface 3 b of the rotating portion 3, and six rows of first magnets 9 are arranged on the inner peripheral surface 8 a of the annular block body 8 of the fixed portion 2. The block body 8 has six stages in the axial direction of the fixed portion 2 (left and right direction in FIG. 1A), and the rotating portion 3 is rotated by the motor 1. The annular block bodies 8 at each stage are arranged with a phase of 10 degrees sequentially.

  Thus, conventionally, in the rotating device as in Patent Document 1, the rotating unit 3 is locked and cannot be rotated by hand at all when stopped, but in the present invention, the rotating unit 3 can be easily rotated with a fingertip. became.

  Further, the current during steady operation is also suppressed by about 5% compared to the rotating device as in Patent Document 1, and it seems that sudden braking was applied to the rotating device as in Patent Document 1 when the stop operation was performed. However, in the present invention, the engine is idling and the mechanical stop is suppressed.

  As described above, both the inner peripheral surface 8a of the annular block body 8 of the fixed portion 2 and the outer peripheral surface 3b of the rotating portion 3 are arranged on the circumference while arranging a large number of first and second magnets 9 and 10 in accordance with the purpose. The magnet arrangement can maintain a uniform and smooth rotational load and suppress the influence of the rotational load of the magnet as much as possible, thereby providing a smooth rotational drive of the rotational device or a rotational device having an appropriate drive source capacity.

  According to the above configuration, the first and second magnets 9 and 10 provided on the inner peripheral surface 8a of the annular block body 8 of the fixed portion 2 and the outer peripheral surface 3b of the rotating portion 3 are not opposed to each other at the same time. By providing one or more sets, the attractive force or repulsive force between the magnets is reduced, and a large driving force is not required at the time of rotation start and continuous rotation.

  Further, the number of first and second magnets 9 and 10 provided on the inner peripheral surface 8a of the fixed portion 2 and the outer peripheral surface 3b of the rotating portion 3 is different, so that one or more sets of magnets that do not face each other at the same time. It can be provided, and the attractive force or repulsive force between the magnets is eased so that a large driving force is not required at the time of starting rotation and continuous rotation.

  Further, the inner peripheral surface 8a of the annular block body 8 of the fixed portion 2 is divided into a plurality of parts in the axial direction of the fixed portion 2 (left and right direction in FIG. 1A), and the inner periphery of the divided annular block body 8 is divided. By disposing the arrangement phase of the first magnets 9 for each surface 8a in the circumferential direction of the inner peripheral surface 8a, it is possible to provide one or more pairs of magnets that are not opposed to each other at the same time. The force is relaxed and a large driving force is not required at the time of rotation start and continuous rotation.

  Moreover, the fixing part 2 material for fixing the annular block body 8 divided into a plurality of parts in the axial direction of the fixing part 2 (left and right direction in FIG. 1A) is fixed to each annular block body 8. By disposing the parts 2 in the circumferential direction, it is possible to provide one or more pairs of magnets that are not opposed to each other at the same time. do not need.

  Moreover, it accommodates in the cylindrical case 7 of the fixing | fixed part 2, and fixes the cyclic | annular block body 8 divided | segmented into plurality in the axial direction (left-right direction of Fig.1 (a)) of this fixing | fixed part 2. By disposing the fixing holes 7a in the annular block body 8 so as to be shifted in the circumferential direction of the cylindrical case 7, it is possible to provide one or more sets of magnets that are not opposed to each other at the same time. It relaxes and does not require a large driving force at the time of starting rotation and continuous rotation.

  In the above-described embodiment, an example in which a plurality of annular block bodies 8 are inserted into the cylindrical case 7 has been described. However, the cylindrical case 7 is omitted, and a plurality of annular block bodies 8 are respectively provided. By connecting by various fixing methods that are fastened by pins, screws, etc., the phase in which the first magnet 9 is arranged for each inner peripheral surface 8a of each annular block body 8 divided in the same manner as described above is included in the phase. It can also be arranged shifted in the circumferential direction of the peripheral surface 8a.

  In the said embodiment, although the separation pitch of each of the 1st, 2nd magnets 9 and 10 was made into the same pitch, as another structure, the cyclic | annular block body 8 which opposes the outer peripheral surface 3b of the rotation part 3 of the fixing | fixed part 2 is used. Of the first magnets 9 provided on the inner peripheral surface 8a of each of the first and second magnets 9, or a second pitch provided on the outer peripheral surface 3b facing the inner peripheral surface 8a of the annular block body 8 of the fixed portion 2 of the rotating portion 3. It is also possible to adopt a configuration in which at least one of the spacing pitches between the magnets 10 is different.

  According to such a configuration, the magnets of the first and second magnets 9, 10 provided on the inner peripheral surface 8 a of the annular block body 8 of the fixed portion 2 and the outer peripheral surface 3 b of the rotating portion 3, respectively. Since at least one of the spacing pitches is different, it is possible to provide one or more pairs of magnets that do not face each other at the same time, and it is necessary to relieve the attractive force or repulsive force between the magnets and require a large driving force at the time of starting rotation and continuous rotation. do not do.

  Moreover, although the said embodiment demonstrated the example when the internal peripheral surface 8a of the annular block body 8 which opposes the outer peripheral surface 3b of the rotation part 3 of the fixing | fixed part 2 was divided | segmented into plurality in the axial direction of the fixing | fixed part 2. As another configuration, there are a plurality of outer peripheral surfaces 3b facing the inner peripheral surface 8a of the annular block body 8 of the fixed portion 2 of the rotating portion 3 in the axial direction of the rotating portion 3 (left and right direction in FIG. 1A). A plurality of phases are arranged in the axial direction of the rotating unit 3 (left and right direction in FIG. 1A). It can also be set as the structure which shifted and arrange | positioned for each outer peripheral surface 3b divided | segmented into this to the circumferential direction of this outer peripheral surface 3b.

  According to such a configuration, the outer peripheral surface 3b of the rotating portion 3 is divided into a plurality of portions in the axial direction of the rotating portion 3, and the arrangement phase of the second magnet 10 is set to the outer peripheral surface for each of the divided outer peripheral surfaces 3b. By shifting the arrangement in the circumferential direction of 3b, it is possible to provide one or more pairs of magnets that do not face each other at the same time, reducing the attractive force or repulsive force between the magnets, and requiring a large driving force at the time of rotation start and continuous rotation And not.

  In the above-described embodiment, the plurality of annular block bodies 8 are divided in the axial direction of the fixed portion 2. However, as another configuration, the rotating portion 3 is configured in the axial direction of the rotating portion 3 (FIG. ) In the left-right direction), and the outer peripheral surface 3b of the columnar block body is opposed to the inner peripheral surface 8a of the fixing portion 2, and the columnar block body The second magnets 10 are arranged at a predetermined pitch in the axial direction of the rotating part 3 on the outer peripheral surface 3b, and two fixing parts for fixing the columnar block body are used in the axial direction of the rotating part 3 (FIG. 1A). It is also possible to adopt a configuration in which the columnar block bodies divided into a plurality of (left and right directions) are shifted in the circumferential direction of the rotating portion 3.

  According to such a configuration, the columnar block body is provided with a fixing member for fixing a columnar block body (not shown) that is divided into a plurality of parts in the axial direction of the rotating portion 3 (left and right direction in FIG. 1A). By disposing the rotating unit 3 in the circumferential direction every time, it is possible to provide one or more pairs of magnets that are not opposed to each other at the same time, and relieve the attraction force or repulsive force between the magnets to start rotation and during continuous rotation. Does not require a large driving force.

  The motor 1 shown in FIG. 1 is composed of a submersible motor 1, and a suction pipe 12 serving as a suction inlet and a suction pipe 13 serving as a suction inlet are provided on the side opposite to the side where the submersible motor 1 is attached. The rotating device according to the present invention is an example configured as a foam generating device.

  A connecting member 4 is attached to the motor shaft 1a of the submersible motor 1, and a pump blade 14 serving as a rotary blade is attached to the connecting member 4. A rotating shaft 3 a that is rotatably supported by a bearing member 6 provided at the other end of the fixed portion 2 is attached to the connecting member 4. Further, in the axial direction of the rotating shaft 3a (left and right direction in FIG. 1A), a restraining member is located at a position corresponding to the entire length in the axial direction of the rotating portion 3 (left and right direction in FIG. 1A) from the connecting member 4. The motor shaft 1a, the connecting member 4, the pump blade 14, the rotating shaft 3a, and the restraining member 15 of the submersible motor 1 are configured to rotate integrally.

  The foam generating apparatus having the above-described configuration can be installed in the water to be treated, for example, and can act as a water purification device. The intake pipe 13 communicates with the outside air and takes in air as an example of gas into the fixed portion 2, and the liquid suction pipe 12 takes in water to be treated as a treatment liquid in which the foam generating device is installed. The intake pipe 13 can be configured using a long and flexible tube (hose), and can also be configured using a rigid tube communicating with the outside air. One or a plurality of intake pipes 13 can be provided.

  The intake pipe 13 is configured such that the diameter of the intake port of the connection port to the fixed portion 2 is increased, and the diameter of the intake pipe 13 is increased beyond the liquid level when the foam generating device is installed under water. Further, as shown in FIG. 1B, the intake pipe 13 is provided so that the suction port of the connection port to the fixed part 2 is tangential to the liquid flow direction in the fixed part 2.

  As a result, even if the suspended matter in the water installed with the foam generating device submerged flows back to the intake pipe 13, a large suction force can be applied to remove the suspended substance from the intake pipe 13. The clogging of the tube 13 can be prevented. Although the suction pressure of Patent Document 1 is about several tens of cmAq (water column pressure), the suction pressure of the present embodiment can be improved to about 1.5 mAq (water column pressure).

  A discharge port (not shown) is provided at a portion corresponding to the pump blade 14 of the fixed portion 2, and the water to be treated containing ultrafine bubbles sent out by the pump blade 14 is sent to the outside.

  The tip 12a of the suction pipe 12 is disposed on the submersible motor 1 side, and the tip 12a of the submersible motor 1 and the suction pipe 12 is designed to remove dust such as a wire mesh as a filter in order to prevent unintended dust inflow. 16 is provided.

  As shown in FIG. 6, the second magnet 10 provided on the outer peripheral surface 3 b of the rotating portion 3 is inclined by a trapezoidal projection 3 c having a trapezoidal cross section provided at a predetermined pitch in the circumferential direction of the rotating portion 3. It is attached to the surface, and this protrusion 3c also serves as a rotary blade in the centrifugal pump.

  The air sucked from the intake pipe 13 in the gap 17 formed between the outer peripheral surface 3b of the rotating part 3 and the inner peripheral face 8a of the annular block body 8 of the fixed part 2 becomes the water to be treated sucked from the liquid suction pipe 12. The mixture is mixed to generate countless minute bubbles, and the oxygen component in each bubble is dissolved in the water to be treated.

  When the submersible motor 1 is rotated, the rotational driving force is transmitted to the connecting member 4 connected to the motor shaft 1a, the pump blade 14, the rotating shaft 3a, and the restraining member 15, so that the submersible motor 1 and the rotating unit 3 are integrated. Rotate.

  On the other hand, the pump blade 14 that rotates integrally with the submersible motor 1 plays the same role as the centrifugal pump. That is, when the pump blade 14 rotates, the water to be treated in the gap 18 communicated with the gap 17 is scraped up and down in FIG. 1A by the pump blade 14 and discharged to the outside from a discharge port (not shown). The water pressure in the gap 18 is reduced to atmospheric pressure or lower (negative pressure).

  Therefore, the pressure in the gap 17 communicating with the gap 18 also becomes negative, the water surface in the fixed portion 2 descends, air flows in from the intake pipe 13, and water to be treated flows in from the liquid suction pipe 12.

  The water to be treated that has flowed into the gap 17 is dragged by the high-speed rotation of the rotating unit 3 and rotates at a high speed. As a result, the descending water surface in the fixed portion 2 undulates and foams at the same time, and countless small vortices as secondary flows are generated below the water surface. The vortex generation phenomenon at this time is a phenomenon called Taylor Couette Flow (Taylor Vortex).

  Here, the Taylor vortex has a fixed portion 2 made of a large cylinder and a rotating portion 3 made of a small cylinder or a column therein, and a gap 17 that is a space between the two is filled with water to be treated. Then, due to the rotation of the rotating unit 3, the water to be treated in the vicinity receives the centrifugal force and is pushed out toward the fixing unit 2. Then, an action / reaction force acts on the water to be treated so as to maintain the state equilibrium, and the action water is pushed out, while returning to the rotating unit 3 side. As a result, countless small vortices are generated.

  Therefore, the air that has flowed from the intake pipe 13 is efficiently mixed with the water to be treated that has flowed from the liquid suction pipe 12, and becomes innumerable minute bubbles. Further, the oxygen component in each generated microbubble is efficiently dissolved in the water to be treated that is deficient in oxygen.

  The water to be treated in the gap 17 flows into the gap 17 under the synergistic effect of the electromagnetic action of the first magnet 9 and the second magnet 10 while increasing the number of microbubbles and the amount of dissolved oxygen. All the microbubbles in the water to be treated are divided and subdivided to generate ultrafine bubbles, and the oxygen component in each ultrafine bubble is further dissolved in the water to be treated.

  The water to be treated containing ultrafine bubbles and dissolved oxygen is discharged from the discharge port (not shown) in the vertical direction of FIG. 1A by the pumping action by the rotation of the pump blade 14, and the water to be treated is installed with the foam generating device. Diffused into water. The ultrafine bubbles and dissolved oxygen formed in this way do not float in the water area to be treated in a short time, can stay in the water area for a very long time, and diffuse throughout the water area. I can do it.

  As is well known, each of the water molecules has a hydrogen-oxygen-hydrogen bond state that is not linear, and the probability distribution of electrons is not symmetric, thus forming an electric dipole. Therefore, these water molecules do not exist alone in the liquid phase, and some of them gather together by hydrogen bonds to form a cluster. The size and shape of the clusters vary depending on the type and amount of dissolved impurities and the temperature.

  The water molecules (ionic water) forming the electric dipoles are a first magnet 9 and a second magnet provided on the inner peripheral surface 8a of the annular block body 8 of the fixed portion 2 and the outer peripheral surface 3b of the rotating portion 3, respectively. When the relative motion with the magnetic field by 10 and the relative motion are given, energy (mainly the energy of the rotational motion of the molecule, and the energy of the stretching and translational motion) is given, and the energy level is raised. .

  That is, as a result of the water molecules being activated, the clusters of the water molecules become smaller, so that oxygen in the ultrafine bubbles easily dissolves between the clusters, and the ultrafine bubbles are easily divided. Furthermore, when the water to be treated, which is a conductive fluid, and the magnetic field move relative to each other, an electric current is induced in the water to be treated. At the same time, an isotropic pressure (magnetic pressure) of B2 / 2μ and a tension in the direction of the magnetic field lines of B2 / μ (here, the vertical direction) are generated. B is the strength of the magnetic force, and μ is the magnetic permeability of the magnetic flux. These phenomena also make water molecule clusters smaller.

  On the other hand, since oxygen molecules are paramagnets that form a magnetic dipole, when given relative motion with the magnetic field formed by the first magnet 9 and the second magnet 10, energy (mainly rotation of the molecules) is thereby generated. Kinetic energy and translational energy) are given to raise the energy level. As a result, the oxygen molecules in the magnetic field are activated, and the oxygen molecules on the bubble surface easily break through the boundary surface of water and dissolve therein.

  As the diameter of the ultrafine bubbles released into the water to be treated becomes finer, all the ultrafine bubbles do not float on the water surface in a short time, and therefore the water retention time becomes extremely long and extremely fine. The surface area of the entire bubbles, that is, the contact area between the entire ultrafine bubbles and the water to be treated becomes extremely large.

  Thus, the ionic water diffused into the water to be treated efficiently oxidizes (N-polar repulsion) or alkalins (S-polar repulsion) various objects. Ionic water produced by oxidation sterilizes only pathogenic bacteria and microorganisms. Ionized water generated by alkalinization decomposes proteins and oils and fats and exhibits excellent detergency.

  In addition, when sunlight is present, planktonic algae (such as blue-green algae) can be killed and aggregated. Micro suspended matter produced by the death and aggregation of planktonic algae adheres to bubbles and floats on the surface of the water, forming floating scum. Furthermore, these microscopic bubbles can be bound innumerably to sludge (microorganism layer) at the bottom of the water to give them buoyancy and float in large units.

  The floating scum is periodically collected and discarded to achieve the water purification process for the target water area.

  In addition, the rotating portion at each point in the gap 17 is caused by the action of the first magnet 9 and the second magnet 10 provided on the inner peripheral surface 8a of the annular block body 8 of the fixed portion 2 and the outer peripheral surface 3b of the rotating portion 3. 3 radial magnetic fields are generated, and the aforementioned interaction between the magnetic field and water molecules, the interaction between the induced current and water molecules, and the interaction between the magnetic field and oxygen molecules, and their synergistic effects, Finer bubbles can be generated in the water to be treated in the gap 17, and more oxygen components in the ultrafine bubbles can be dissolved in the water to be treated.

  Various gas generators can be used in combination with the bubble generator. For example, the ozone generator or the active air generator is installed on the ground, and is airtight and watertightly connected to the intake pipe 13 of the fixed portion 2 via a long and flexible intake pipe.

  The intake pipe is laid under the surface of the water area during operation so as not to damage the water area landscape to be treated. Ozone or active air generated in these devices is sent from the flexible intake pipe into the fixed portion 2 through the intake pipe 13.

  By sending ozone-containing air or active air into the intake pipe 13 instead of outside air, the water purification action can be further enhanced by the synergistic effect of these and ultrafine bubbles.

  If rainwater or the like flows into the water area to be treated and its water level fluctuates, the water depth and water pressure in the intake pipe 13 may fluctuate, and the optimal mixing ratio between the water to be treated and air may collapse. Correspondingly, the foam generator body is connected to an appropriate float and floated from the bottom of the water so that the water depth position of the foam generator body does not fluctuate even when the water level fluctuates. Can be prevented from fluctuating.

  When the water to be treated is severely soiled or acidified, in order to make an immediate improvement, it is possible to spray or spray chemicals such as a neutralizing agent and / or a flocculant for the first period only. As a result, the organic matter is forcedly levitated and the pH is improved. After improvement with chemicals, water purification can be continued with a foam generator. Bacteria (aerobic bacteria or ammonia-degrading bacteria) are introduced after water purification has progressed to some extent. The water to be treated can be sufficiently purified by the above synergistic effect.

  Next, a second embodiment of the rotating device according to the present invention and the foam generating device including the same will be described with reference to FIGS. 11 and 12. FIG. 11 is a cross-sectional explanatory view showing the configuration of the second embodiment of the rotating device and the foam generating device having the same according to the present invention, and FIG. 12 is a view for explaining the magnet arrangement of the second embodiment. In addition, what was comprised similarly to the said 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.

  In the present embodiment, as shown in FIGS. 11 and 12, the longitudinal directions of the first and second magnets 9 and 10 provided on the fixed unit 2 side and the rotary unit 3 side of the rotating device (the vertical direction in FIG. 11), respectively. ) Is inclined at a predetermined angle with respect to the direction of the rotation axis 3a (the vertical direction in FIG. 11) of the rotating unit 3, and the first and second magnets 9 and 10 are moved along with the rotation of the rotating unit 3. It is configured to cross each other and face each other in the longitudinal direction (vertical direction in FIG. 11).

  The rotating part 3 of the present embodiment is rotated by a rotating shaft 3a being cantilevered by a connecting member 4 on a motor shaft 1a of a motor 1 serving as a rotation drive source. As shown in FIG. 12, the rotary shaft 3a of the present embodiment is formed in a square cross section, and the longitudinal direction of the second magnet 10 on each of its four side surfaces 3a1 (vertical direction in FIG. 12 (a)). Is fixed by screws 35 at a predetermined angle with respect to the direction of the rotating shaft 3a (the vertical direction in FIG. 12A). In this embodiment, the inclination angle α of the second magnet 10 is set to about 4.3 degrees with respect to the direction of the rotation axis 3a. The longitudinal direction (vertical direction in FIG. 11) of the first magnet 9 attached to the fixing portion 2 of the present embodiment is set and fixed in the same direction as the direction of the rotating shaft 3a (vertical direction in FIG. 11). .

  The pump blade 14 serving as a rotary blade is fixed to the motor shaft 1a, is connected to the rotary unit 3, and rotates integrally with the rotary unit 3. The liquid suction pipe 31 serving as a liquid suction port is constituted by a straight pipe, and the treatment liquid is placed in a gap 17 formed between the fixed part 2 and the rotary part 3 by the negative pressure generated by the rotation of the pump blade 14 serving as a rotary blade. The target water to be treated is inhaled. An intake pipe 13 serving as an intake port is a confluence pipe that is connected to and communicates with a liquid suction pipe 31 that is a straight pipe, and is negatively generated by the rotation of pump blades 14 that serve as rotor blades. As an example of gas, air is sucked into a gap 17 formed between the fixed portion 2 and the rotating portion 3 by pressure. The processing liquid sucked from the liquid suction pipe 31 serving as the liquid suction port and the air sucked from the suction pipe 13 serving as the suction port are mixed in the gap 17 formed between the fixed portion 2 and the rotating portion 3. Then, as described above in the first embodiment, the liquid mixture composed of the water to be treated containing ultrafine bubbles and dissolved oxygen is externally discharged from the discharge port 36 in the left-right direction of FIG. To discharge.

  A small-diameter pipe 32 is inserted into the liquid-absorbing pipe 31 and provided with a small-diameter portion on the upstream side (right side in FIG. 11) in the vicinity of the position where the intake pipe 13 consisting of the confluence pipe of the liquid-absorbing pipe 31 consisting of the straight pipe intersects. The flow rate of the processing liquid sucked in the small-diameter portion formed by the inner diameter of the small-diameter pipe 32 provided in the liquid-absorbing pipe 31 comprising the straight pipe increases, and is sucked from the intake pipe 13 constituted by the confluence pipe. It is possible to generate a negative pressure that increases the air suction input.

In the flow path between the gap 17 formed between the fixed portion 2 and the rotating portion 3 and the outlet of the liquid absorption pipe 31, the gap blocks 33a and 33b can be attached to and detached from the fixed portion 2 with screws 37. A gap channel 34 is formed on the upstream side in the vicinity of the gap 17 by the gap blocks 33a and 33b. The gap block 33b is formed of an annular member having an outer diameter corresponding to the inner diameter of the fixed portion 2, and is detachably attached to the fixed portion 2 with screws 37. Although Kyosuki block 33a attached to the central portion of the bottom plate of the fixed portion 2 is constituted by a generally frustoconical shape whose diameter upwardly in accordance with the size of the rotary portion 3, narrow gap passage 34 The shape will be determined by the relationship.

  Since the flow rate of the processing liquid passing through the gap channel 34 increases, a negative pressure is generated to increase the suction force of the air sucked from the intake pipe 13 serving as an intake port, and air mixing is promoted. I can do it. That is, the treatment liquid sucked from the liquid suction pipe 31 serving as the liquid suction port and the air sucked from the suction pipe 13 serving as the suction port are formed in the gap 17 formed between the fixed portion 2 and the rotating portion 3. It is possible to increase the flow velocity of the processing liquid flowing into the gap 17 on the upstream side in the vicinity to generate a negative pressure that increases the suction force of the air sucked from the intake pipe 13 serving as an intake port, thereby promoting air mixing. .

  According to the above configuration, at least one of the longitudinal directions (vertical direction in FIG. 11) of the first and second magnets 9 and 10 provided on the fixed portion 2 side and the rotating portion 3 side is used as the rotating shaft 3a of the rotating portion 3, respectively. The first and second magnets 9 and 10 are arranged so as to be opposed to each other in the longitudinal direction (vertical direction in FIG. 11) as the rotating part 3 rotates. By disposing the first and second magnets 9 and 10, the opposite sides of the first and second magnets 9 and 10 are deterred in the rotational direction when they approach each other due to the same-polar magnet on which repulsive force acts, or the first and second magnets 9 and 10 The forces on the opposite sides of the magnets can be distributed in the deterring force with respect to the rotation direction when they move away from each other by the different polarity magnets on which the attractive force acts, and the rotation deterring force can be reduced.

  That is, the longitudinal directions (vertical directions in FIG. 11) of the first and second magnets 9 and 10 provided on the fixed portion 2 side and the rotating portion 3 side are inclined at different angles (this embodiment). The inclination angle of the rotating portion 3 of the first magnet 9 with respect to the direction of the rotation axis 3a is 0 °.) For example, the longitudinal direction (vertical direction in FIG. 11) of the first and second magnets 9 and 10 is drawn. In this case, when the N pole and the N pole face each other, or when the N pole and the S pole face each other, the moment becomes a point contact instead of a line contact, and the rotation inhibition force can be reduced.

  On the other hand, since the water to be treated that flows in the gap 17 formed between the fixed portion 2 and the rotating portion 3 apparently flows due to the rotation of the rotating portion 3, for example, the first and second magnets When the longitudinal direction of 9 and 10 is parallel to the direction of the rotation axis 3a of the rotating part 3, the first and second magnets 9 and 10 seem to face the treatment target water flowing obliquely. However, when the longitudinal directions of the first and second magnets 9 and 10 are tilted by a predetermined angle as described above, the first and second tilted longitudinal directions are used. The intersections with the second magnets 9 and 10 continuously move, and apparently, a magnetic force continuously acts on the water to be treated flowing obliquely. As a result, the water to be treated in the gap 17 formed between the fixed portion 2 and the rotating portion 3 increases the number of microbubbles and the amount of dissolved gas while increasing the first magnet 9 and the second magnet. The microbubbles in the water to be treated that have flowed into the gap 17 due to the synergistic action with the electromagnetic action due to 10 are more effectively divided and subdivided, and more microbubbles are generated. The gas component in the ultrafine bubbles can be further dissolved in the treatment liquid.

  Further, the processing liquid sucked from the liquid suction pipe 31 serving as the liquid suction port by the negative pressure generated by the rotation of the pump blade 14 serving as the rotary blade and the air sucked from the suction pipe 13 serving as the suction port are fixed to the fixing portion. 2 is mixed in the gap 17 formed between the rotating part 3 and the fine bubbles are generated and included in the processing liquid, and the mixed liquid can be discharged to the outside through the discharge port 36.

  In addition, from an intake pipe 13 consisting of a merging pipe connected to and communicated with a liquid suction pipe 31 consisting of a straight pipe for sucking processing liquid into a gap 17 formed between the fixed part 2 and the rotating part 3 Air can be sucked into a gap 17 formed between the fixed portion 2 and the rotating portion 3, and negative pressure is applied to the intake pipe 13 made of a merging pipe by the flow velocity of the processing liquid flowing through the liquid suction pipe 31 made of a straight pipe. And the air can be sucked from the intake pipe 13 serving as an intake port.

  Further, the flow rate of the processing liquid flowing through the small diameter portion formed by the inner wall of the small diameter pipe 32 provided in the liquid suction pipe 31 provided in the upstream near the position where the intake pipe 13 formed of the confluence pipe intersects is determined. An intake pipe 13 that becomes larger and generates a larger negative pressure in the intake pipe 13 that is a merging pipe due to the flow velocity of the processing liquid that flows through the small diameter part 32 that is the small diameter pipe 32 of the liquid suction pipe 31 that is a straight pipe. Air can be inhaled from.

  Further, the flow rate of the processing liquid flowing in the gap channel 34 formed on the upstream side in the vicinity of the gap 17 formed between the fixed part 2 and the rotating part 3 is increased, and the process flowing in the gap channel 34 is increased. A large negative pressure is generated by the flow rate of the liquid, and air can be sucked from the intake pipe 13 serving as an intake port.

  With such a configuration, the air suction input can be increased, and air can be easily sucked even when the foam generating device is installed deep in water.

  In addition, the premixing of bubbles is promoted before the processing liquid flows into the gap 17 while maintaining and ensuring the circulating water amount. In addition, the air suction force is increased to facilitate air suction even when the foam generator is installed deep in the water, or the thick intake pipe 13 is used to prevent clogging, which is extremely important depending on the processing liquid. However, it is possible to generate bubbles stably over a wide intake air amount range. Furthermore, a small hole as a liquid flow path can be provided in the fixed portion 2 for adjusting the negative pressure and the liquid flow rate.

  In the present embodiment, a straight pipe is used as the liquid suction pipe 31 for sucking the processing liquid. However, a curved pipe may be used as long as it does not greatly impede the resistance of the liquid flow. Further, although the junction pipe intersecting with the liquid absorption pipe 31 is made orthogonal, it can also be attached at an inclination.

  Hereinafter, actual measurement results of intake air pressure of specific examples A to C and a comparative example will be described. A foam generating apparatus having a submersible motor 1 with a rated output of 400 W shown in FIG. 11 and having sandwiching blocks 33a and 33b in the fixed portion 2 is installed at a water depth of 1 m, and is not shown above the water in the intake pipe 13.

  In each comparative example and example A, an opening / closing cock (not shown) provided on the water top of the intake pipe 13 is opened and closed to reduce the intake air amount to 0 (liter / min), 5 (liter / min), and 7 (liter / min), respectively. , 12 (liter / min), each of the comparative examples and example A when the intake cock of the comparative example when the opening / closing cock is closed and the intake amount is 0 (liter / min) is 100 Table 1 below shows the relative intake pressure in the intake amount expressed in%.

  As shown in Table 1 above, in comparison with the comparative example, in Example A, a stable negative intake amount can be obtained by maintaining a large negative pressure for a long time even if the intake amount increases.

  Table 2 below has the same configuration as that of Example A, and the intake air pressure was measured as Example B when the gap blocks 33a and 33b were provided, and as Example C when the gap blocks 33a and 33b were removed. Is. In Examples B and C, the configuration is the same as in Example A except that the inner diameter of the small-diameter pipe 32 is 18 mm.

Table 2 below shows the relative intake pressure in% when the intake air amount of Example B is 0 (liter / min) when the intake air pressure of C is 100.

  As shown in Table 2 above, in Example B in which the gap blocks 33a and 33b are provided compared to Example C in which the gap blocks 33a and 33b are removed, a larger negative pressure is generated and a stable intake amount is obtained. You can see that
