Hereinafter, specific embodiments of the present invention will be described in detail, but the present invention is not limited to the following embodiments, and the present invention is carried out with appropriate modifications within the scope of the object of the present invention. can do.

<Livestock breeding unit 100>
FIG. 1 is a schematic view showing a planar arrangement of the livestock breeding unit 100 according to the present embodiment. The livestock breeding unit 100 is a facility for breeding livestock (for example, pigs, etc.) including a breeding unit 110 and a drinking water supply channel 120.

The breeding unit 110 is formed in a box shape with an open upper part, and a plurality of livestock are released inside. The breeding unit 110 includes at least a wall unit 111 that surrounds the internal space 110a in which livestock are released. The wall portion 111 is formed of a plurality of panels having a height dimension that cannot be overcome by livestock. The wall portion 111 forms an internal space 110a by connecting a plurality of panels with side edges in the width direction to each other. That is, the livestock breeding unit 100 can be disassembled and assembled, and a plurality of panels forming the wall portion 111 are carried into the installation location, and the plurality of panels are connected to each other to release the livestock in the internal space 110a. Is formed.

In the interior space 110a, a drinking fountain 110b for livestock to drink is arranged along the wall portion 111. An end portion of the drinking water supply path 120 is arranged in the drinking fountain 110b, and a faucet is installed at this end portion.

Further, a bottom plate may be arranged at the bottom of the internal space 110a, and the side edge of the bottom plate and the lower end of the wall portion 111 may be connected to each other. Thereby, for example, even if the livestock breeding unit 100 is installed in the room of the building, it is possible to prevent the floor of the building from being contaminated by livestock excrement or the like. Further, in the internal space 110a, by arranging a floor in which waste wood chips are mixed with bacteria that ferment and decompose excrement, the excrement is decomposed, which is hygienic and removes the excrement. It becomes possible to save labor. Further, by arranging such a floor in the internal space 110a where the livestock is released, the floor is trampled and kneaded by the livestock, so that the fermentation of the fungus is accelerated and the decomposition of excrement is promoted. Is possible.

In the drinking water supply channel 120, one end side of the water passage pipe 121 is connected to a pipe for supplying water, and the other end is arranged in the drinking fountain 110b of the breeding unit 110 to supply the drinking water of livestock to the breeding unit 110. Further, in the drinking water supply path 120, the water activation device 1 is arranged near the other end of the water pipe 121. The tap water supplied from the water supply pipe flows in from one end of the water pipe 121, becomes magnetically treated water magnetically treated by the water activation device 1 in the drinking water supply path 120, and becomes the other end of the water pipe 121. Is supplied to the drinking fountain 110b. As a result, the livestock released to the breeding unit 110 will ingest the magnetically treated water as drinking water.

<Water activation device 1>
FIG. 2 is a schematic view showing the appearance of the water activation device 1 according to the present embodiment. Each member constituting the water activation device 1 is housed inside the housing 10. The housing 10 includes a hollow housing body 11 and lids 12A and 12B provided at both ends of the housing body 11.

FIG. 3 is a schematic view showing the internal state of the housing main body 11 when the lid 12A is removed from the water activating device 1. At least the water pipe 13 and the permanent magnets 14A and 14B are housed inside the housing main body 11. It is preferable that the non-magnetic conductive metal plates 15A and 15B and the yokes 16A and 16B are further housed inside the housing main body 11.

As will be described later, in the water activation device 1, the water pipe 13, the permanent magnets 14A and 14B and the yokes 16A and 16B are covered with the filling member 17 (see FIG. 4D). 13. The description is omitted in order to indicate the permanent magnets 14A and 14B and the yokes 16A and 16B.

[Water pipe 13]
FIG. 4A is an exploded view of the water pipe 13, the permanent magnets 14A, 14B and the yokes 16A, 16B of the water activation device 1, and is a diagram for explaining the manufacturing method of the water activation device 1.
One end of the water pipe 13 is connected to one end side of the water pipe 121 (see FIG. 1), the other end is connected to the other end side of the water pipe 121, water passes through the inside, and threads are threaded at both ends 13A and 13B. Has. The shape of the thread is not particularly limited as long as it can be screwed with the adjacent water pipe 121, and may be a male thread or a female thread. As shown in FIG. 2, the water pipe 13 is fixed to the housing 10 by two nuts screwed with the threads of both ends 13A and 13B, respectively.

Returning to FIG. 4A, in the extending direction (longitudinal direction) of the water pipe 13, the wall thickness of the water pipe 13 at the portion 13C having the magnetic force surface on the outside (the portion different from both ends 13A and 13B of the water pipe 13) is As long as the water pipe 13 is not destroyed by the force applied from the fluid (water) flowing inside the water pipe 13, it is preferable that the water pipe 13 is as thin as possible (activity by magnetic force with respect to the water passed inside the water pipe 13). Can promote the change).

From the viewpoint of applying a magnetic force to the fluid passing through the water pipe 13, the upper limit of the wall thickness of the intermediate portion (the portion 13C having the magnetic action surface on the outside) is the portion having the thread (both ends 13A of the water pipe 13). , 13B) is less than the wall thickness of the water pipe 13. Specifically, when the wall thickness of the water pipe 13 is a steel pipe of 3.0 mm, the wall thickness of the intermediate portion of the water pipe 13 (the portion 13C having the magnetic action surface on the outside) is 0.5 mm or more and 2.5 mm. The following is preferable.

For example, when the wall thickness of the water passage tube 13 is about 3.0 mm and the magnetic force directly under the permanent magnets 14A and 14B is 4,000 gauss, the intermediate portion of the water flow tube 13 (the magnetic action surface is provided on the outside). When the wall thickness of the holding portion 13C) is set to about 1.5 mm, which is half the size of about 3.0 mm, the magnetic force directly under the permanent magnets 14A and 14B becomes 4,500 gauss (that is, the magnetic force is 11%). The above will be improved.). The water activating device 1 may have a limited mounting location, and there is a demand for a compact outer shape. Further, in the water activation device 1, the permanent magnets 14A, 14B and the like are arranged inside the housing 10, the space inside the housing 10 is limited, and in order to improve the magnetic force, the permanent magnets 14A are simply placed. , 14B cannot be increased in size. Therefore, by making the wall thickness of the intermediate portion of the water pipe 13 (the portion 13C having the magnetic action surface on the outside) thinner than both ends, it is possible to achieve the contradictory effects of saving space and improving the magnetic force. Will be.

The wall thickness of the water pipe 13 at the portion having a thread (the portion corresponding to both ends 13A and 13B of the water pipe 13) is different from the portion 13C having the magnetic action surface on the outside (the portion 13A and 13B at both ends of the water pipe 13). ) Is thicker than the wall thickness of the water pipe 13. This is because threads are provided on the inner surface or the outer surface of the water pipe 13, and if the wall thickness of the portion having the threads is too thin, the strength of the water pipe 13 is hindered.

The material of the water pipe 13 is not particularly limited as long as it has threads at both ends 13A and 13B, and may be a metal pipe or a resin pipe.

Above all, in order to more efficiently activate the water passed through the inside of the water pipe 13, the water pipe 13 is preferably made of a non-magnetic material.

Examples of the non-magnetic metal pipe include austenite steel stainless steel pipe (SUS304 and the like). Examples of the resin pipe include a polyethylene pipe, a polyvinyl chloride pipe, a cross-linked polyethylene pipe, a polybutene pipe and the like.

[Permanent magnets 14A, 14B]
The types of permanent magnets 14A and 14B are not particularly limited. The types of permanent magnets 14 include alnico magnets, KS steels, MK steels, ferrite magnets, samarium cobalt magnets, neodymium magnets, placeodium magnets, neodium / iron / boron magnets, samarium nitrogen iron magnets, ferromagnetic nitrided iron, platinum magnets, and cerium. -Cobalt magnets and the like can be mentioned.

The permanent magnets 14A and 14B are provided so as to face each other with the extending direction (longitudinal direction) of the water pipe 13 interposed therebetween. Then, one permanent magnet 14A is arranged so that the surface facing the water pipe 13 is the N pole, and the other permanent magnet 14B is arranged so that the surface facing the water pipe 13 is the S pole. .. As a result, the surface having the N pole of one permanent magnet 14A and the surface having the S pole of the other permanent magnet 14B serve as magnetic action surfaces that cause magnetism to act on the water passing through the inside of the water pipe 13, respectively. Function. The magnetic action surface is provided substantially parallel to the extending direction (longitudinal direction) of the water pipe 13 in at least a part of the region different from both ends 13A and 13B of the water pipe 13.

In the present embodiment, in the extending direction (longitudinal direction) of the water pipe 13, the wall thickness of the water pipe 13 at the portion 13C having the magnetic action surface on the outside (the portion different from both ends 13A and 13B of the water pipe 13) is a screw. It is thinner than the wall thickness of the water pipe 13 at the portion having a mountain (the portion corresponding to both ends 13A and 13B of the water pipe 13). As a result, the magnetic force acting on the fluid passing through the water pipe 13 can be further increased.

Further, it is preferable that a plurality of permanent magnets 14A and 14B are arranged at predetermined intervals along the direction in which the water pipe 13 extends. By doing so, a gradient of magnetic force is created, and the fluid flowing in the water pipe 13 can be further activated.

Further, the permanent magnets 14A and 14B are formed in a rectangular parallelepiped shape, but the present invention is not limited to this, and for example, the surface facing the water pipe 13 may be formed in a curved shape along the outer periphery of the water pipe 13. .. As a result, no gap is formed between the permanent magnets 14A and 14B and the water pipe 13, and the magnetic force can be concentrated on the water passing through the water pipe 13 without waste.

[Non-magnetic conductive metal plates 15A, 15B]
As shown in FIG. 3, in the present embodiment, it is preferable that a pair of non-magnetic conductive metal plates 15A and 15B are arranged on the side surface of the permanent magnet 14.

In the water activation device 1, a magnetic force is generated from the N pole of the permanent magnet 14A toward the S pole of the permanent magnet 14B. When a fluid (water) flows in the water passage tube 13 on which this magnetic force acts, it is orthogonal to the direction of the fluid and the direction of the magnetic field lines of this magnetic force (from the magnetic action surface of the permanent magnet 14A to the magnetic action surface of the permanent magnet 14B). An electromotive current is generated in a direction orthogonal to the direction in which it is headed.

The non-magnetic conductive metal plates 15A and 15B are provided to induce and charge the electromotive force generated in this way so as not to cause a discharge loss, and to efficiently discharge the electrons generated by the charging into the fluid.

The pair of non-magnetic conductive metal plates 15A and 15B face each other with the magnetic action surface of the permanent magnets 14A and 14B interposed therebetween, and the surfaces are arranged to face each other on the magnetic action surface of the permanent magnets 14A and 14B. It is arranged on the side of.

[Yoke 16A, 16B]
The water activation device 1 preferably further includes yokes 16A and 16B. The yokes 16A and 16B are arranged on the opposite side of the magnetic action surface of the permanent magnets 14A and 14B. Both ends of the yokes 16A and 16B are bent in a substantially U shape on the magnetic action surface side of the permanent magnets 14A and 14B, and are arranged in parallel with the magnetic action surface of the permanent magnets 14A and 14B. A bent portion 16b, which is an example of both ends, extends from both ends of the central portion 16a and the permanent magnets 14A and 14B to the magnetic action surface side of the permanent magnets 14A and 14B, respectively.

The yokes 16A and 16B have a function of increasing the attractive force of the permanent magnets 14A and 14B. The material of the yokes 16A and 16B is not particularly limited as long as it is a magnetic material that enhances the attractive force of the permanent magnets 14A and 14B. Examples include boards.

In the example shown in FIG. 3, the end portion of the bent portion 16b of the yoke 16A and the end portion of the bent portion 16b of the yoke 16B are arranged at intervals from each other. However, the present invention is not limited to this, and the bent portion 16b of the yoke 16A and the bent portion 16b of the yoke 16B may be formed so that the ends thereof are in contact with each other. As a result, it is possible to prevent the magnetic flux from leaking from the gap between the end portion of the bent portion 16b of the yoke 16A and the end portion of the bent portion 16b of the yoke 16B, and it is possible to increase the magnetic flux density inside the water pipe 13. ..

In the present embodiment, the surfaces of both ends (bent portions 16b) of the yokes 16A and 16B facing the permanent magnets 14A and 14B in the direction substantially orthogonal to the magnetizing direction of the permanent magnets 14A and 14B, and the permanent magnets 14A , The distance between the ends of 14B facing each other and the ends in the direction orthogonal to each other is more than 1/2 times the thickness of the permanent magnets 14A and 14B (dimensions of the permanent magnets 14A and 14B in the opposite directions). It is preferably large, and preferably about 1.5 times or more the thickness of the permanent magnets 14A and 14B. Since both ends of the yokes 16A and 16B and the permanent magnets 14A and 14B are separated from each other, the magnetic flux density is increased due to the short circuit of the magnetic circuit from the N pole of the permanent magnet 14A to the S pole of the permanent magnet 14B. It can be prevented from decreasing.

[Filling member 17]
Although it is not an essential configuration, it is preferable that the filling member 17 (see FIG. 4D described later) is formed inside the housing 10.

The filling member 17 is an internal space of the housing 10, and is a gap between the permanent magnets 14A and 14B housed inside the housing 10, a pair of non-magnetic conductive metal plates 15A and 15B, and yokes 16A and 16B. It is a solidified material of a fluid filler filled in.

By forming the filling member 17, even if water or the like enters the inside of the housing 10 from the outside or dew condensation occurs inside the housing 10, the permanent magnets 14A, 14B covered with the filling member 17 Since it is possible to prevent external moisture and the like from adhering to the non-magnetic conductive metal plates 15A and 15B and the yokes 16A and 16B and causing rust, the magnetic performance and water activation performance of the water activating device 1 can be maintained for a long period of time. It can be maintained stably over the period.

Further, since the filling member 17 can prevent the permanent magnets 14A and 14B arranged inside the housing 10 from rattling, the permanent magnets 14A and 14B and the non-magnetic conductive metal plates 15A and 15B can be prevented. It is possible to reduce the occurrence of misalignment or distortion in the arrangement with the yokes 16A and 16B and the occurrence of cracks and chips in the permanent magnets 14A and 14B, and the magnetic performance of the water activator 1 can be improved. Water activation performance can be maintained.

The material of the filling member 17 is not particularly limited as long as it can be filled in the gap between the permanent magnets 14A and 14B, the pair of non-magnetic conductive metal plates 15A and 15B, and the yokes 16A and 16B. For example, silicone resin and the like can be mentioned.

[Housing 10]
Returning to FIG. 2, the housing 10 includes a hollow housing body 11 (for example, a cylindrical shape) and lids 12A and 12B provided at both ends of the housing body 11. The housing 10 is not limited to a cylindrical shape as long as it has a hollow shape, and may have an arbitrary shape such as a polygonal pillar shape such as a quadrangular prism shape.

The housing 10 (housing body 11, lids 12A, 12B) is made of, for example, stainless steel, but is a member formed of ABS resin, and is plated with three layers of copper plating, nickel plating, and chrome plating. It may be covered with a layer.

The lids 12A and 12B have side edges formed by the outer diameter and outer diameter of both ends of the housing body 11 and the outer diameter and outer diameter of substantially the same shape. For example, the lids 12A and 12B have a hemisphere with respect to the cylindrical housing body 11. It is formed in a shape and has a through hole at its substantially center. Such lids 12A and 12B are attached to both ends of the housing body 11, and both ends of the water pipe 13 are projected from the through holes, whereby the central axis of the hollow portion of the housing body 11 and the central axis of the water pipe 13 are formed. The water pipe 13 and the like can be stored inside the housing 10 so as to be integrated with each other.

In the present embodiment, the water pipe 13 and the like are housed in the hollow portion of the hollow housing body 11 so that the central axis of the hollow portion of the housing body 11 and the central axis of the water pipe 13 are integrated and housed. It is preferable that the main body 11 and the lids 12A and 12B are welded and integrated by a laser.

<Manufacturing method of water activation device 1>
Hereinafter, a method for manufacturing the water activation device 1 according to the present embodiment will be described with reference to FIGS. 4A to 4F.

[Assembly of members constituting the inside of the housing 10]
First, as shown in FIG. 4A, a water pipe having a thickness of a member constituting the inside of the housing 10, specifically, an intermediate portion (a portion sandwiched between the permanent magnets 14A and 14B) thinner than both ends 13A and 13B. 13. Prepare permanent magnets 14A and 14B, non-magnetic conductive metal plates 15A and 15B, and yokes 16A and 16B.

At that time, a plurality of permanent magnets 14A are magnetized on the substrate portion of the yoke 16A at predetermined intervals along the longitudinal direction. At this time, the substrate portion of the yoke 16A and the S pole of the permanent magnet 14A are in contact with each other. Further, the permanent magnet 14A is separated from both ends of the yoke 16A by more than 1/2 of the thickness of the permanent magnet 14A.

Further, a plurality of permanent magnets 14B are magnetized on the substrate portion of the yoke 16B at predetermined intervals along the longitudinal direction. At this time, the substrate portion of the yoke 16B and the N pole of the permanent magnet 14B are in contact with each other. Further, the permanent magnet 14B is separated from both ends of the yoke 16B by more than 1/2 of the thickness of the permanent magnet 14A.

Subsequently, as shown in FIG. 4B, non-magnetic conductive metal plates 15A and 15B are inserted between both ends of the yoke 16A and the permanent magnet 14A, respectively, and the water passage tube 13 is arranged on the permanent magnet 14A. , A yoke 16B on which a plurality of permanent magnets 14B are magnetized is put on it. As a result, the state shown in FIG. 4C is obtained. At this time, since the plurality of permanent magnets 14A and the plurality of permanent magnets 14B attract each other, the water passage tube 13, the permanent magnets 14A and 14B, the non-magnetic conductive metal plates 15A and 15B, and the yokes 16A and 16B are integrated. It is fixed at.

[Filling of filling member 17]
Next, as shown in FIG. 4D, fluidity is established in the gap between the water pipe 13 shown in FIG. 4C, the permanent magnets 14A and 14B, the pair of non-magnetic conductive metal plates 15A and 15B, and the yokes 16A and 16B. The filling member 17 (for example, silicon or the like) is poured so as to be filled, and the filling material is applied around the yokes 16A and 16B.

[Storage in housing body 11]
Next, as shown in FIG. 4E, the water pipe 13, the permanent magnets 14A and 14B, the non-magnetic conductive metal plates 15A and 15B, and the yokes 16A and 16B shown in FIG. 4C are placed in the hollow portion of the hollow housing body 11. The assembled member 18 that has been assembled and filled with the filling member 17 is housed in the hollow portion of the housing main body 11.

[Joining the housing body 11 and the lids 12A and 12B]
Next, as shown in FIG. 4F, both ends 13A and 13B of the water pipe 13 of the assembled member 18 housed in the housing body 11 are inserted into the through holes of the lids 12A and 12B, respectively, to form the housing body 11. The lids 12A and 12B are joined to both edges by laser welding, respectively. Then, if necessary, it is polished.
Through the above steps, the water activation device 1 of the present embodiment is manufactured.

As the type of laser used for laser welding, for example, a YAG laser is desirable. As a result, when the housing body 11 and the lids 12A and 12B are welded and integrated, it is possible to prevent the magnetic force of the permanent magnets 14A and 14B from being lowered by heat and the filling member 17 from being eluted to the outside.

For details in the welding process, first, the housing body 11 and the lid 12A are temporarily fixed by a YAG laser. The YAG laser preferably has a voltage of 350 to 370 V and a frequency of 30 Hz. In this state, the assembly member 18 is inserted into the hollow portion of the housing body 11, and the end portion 13A of the water pipe 13 is inserted into the through hole of the lid body 12A.

After that, the end portion 13B of the water pipe 13 is inserted into the through hole of the lid body 12B, and the housing body 11 and the lid body 12B are temporarily fixed by a YAG laser.

After that, the housing body 11 and the lids 12A and 12B are main-welded by the YAG laser, and then the lids 12A and 12B and the water passage tube 13 are main-welded by the YAG laser.

In this way, the housing body 11 and the lids 12A and 12B are main-welded, and then the lids 12A and 12B and the water-passing pipe 13 are main-welded to form the lids 12A and 12B and the water-passing pipe. It is possible to prevent the temporary fixing of the housing body 11 and the lids 12A and 12B from coming off when the 13 is main-welded.

In the main welding, the welding may be performed by the same welding machine as in the temporary fixing. For example, in the temporary fixing, a handy type welding machine is used, and in the main welding, the housing body 11 is temporarily fixed (for example, the temporarily fixed housing body 11). A robot-type welder capable of welding (by rotating the lids 12A and 12B with respect to the laser irradiation position) may be used.
For example, when using a robot-type welding machine, the laser width (time for one pulse) is 11.9 millisec, the pulse frequency is 22 Hz, the welding speed is 30 cm / min, and the output is 320 to 350 W. May be good.
The welding speed is a speed at which the temporarily fixed housing body 11 and the lids 12A and 12B are rotated with respect to the laser irradiation position.

In addition to the YAG laser, the welding method may be carbon dioxide laser arc welding, gas welding, or the like.

<Experimental example>
Next, an experimental example in which the magnetic flux density inside the water pipe 13 is measured when the modes of the yokes 16A and 16B of the water activation device 1 according to the present embodiment are changed will be described.
FIG. 5 is a diagram schematically showing the inside of the water activation device 1 in the experimental example.
In the example shown in FIG. 5, the bent portion 16b of the yoke 16A and the bent portion 16b of the yoke 16B are different from the example shown in FIG. 3 in that their ends are formed so as to be in contact with each other.
Further, the thickness of the permanent magnets 14A and 14B (dimensions in the directions of the permanent magnets 14A and 14B facing each other) in the experimental example described below is 10 mm. Further, the yokes 16A and 16B in the experimental examples described below were formed of pure iron (SUY-1).

[Experimental Example 1]
In Experimental Example 1, between the surface of the bent portions 16b of the yokes 16A and 16B facing the permanent magnets 14A and 14B and the ends of the permanent magnets 14A and 14B in a direction orthogonal to the facing direction (magnetization direction). The magnetic flux density inside the water passage tube 13 was measured at each distance by changing the distance S (see FIG. 5). Further, in Experimental Example 1, the thickness t of the yokes 16A and 16B is 4.5 mm.

Specifically, in Experimental Example 1, the above distance is set between 5 mm (dimension of 1/2 the thickness of the permanent magnets 14A and 14B) and 20 mm (dimension of twice the thickness of the permanent magnets 14A and 14B). The magnetic flux density inside the water pipe 13 was measured at each distance.

FIG. 6 is a graph showing the experimental results of Experimental Example 1. In FIG. 6, the horizontal axis indicates the distance S (see FIG. 5) (unit: mm) between the bent portions 16b of the yokes 16A and 16B and the permanent magnets 14A and 14B. Further, in FIG. 6, the vertical axis shows the average magnetic flux density (unit: T) which is the average of the values of the magnetic flux densities measured at a plurality of points along the center line of the water pipe 13.

From the experimental results of Experimental Example 1 shown in FIG. 6, the average magnetic flux density (unit:) is increased by separating the distance S (see FIG. 5) between the bent portions 16b of the yokes 16A and 16B and the permanent magnets 14A and 14B. It was found that T) increased, but the average magnetic flux density did not increase even if the distance S was separated by 15 mm (1.5 times the thickness of the permanent magnets 14A and 14B) or more.

From the experimental results of Experimental Example 1, the distance S (see FIG. 5) between the bent portions 16b of the yokes 16A and 16B and the permanent magnets 14A and 14B is ½ of the thickness of the permanent magnets 14A and 14B. It was confirmed that it is preferable that the thickness is larger than double and is approximately 1.5 times or less the thickness of the permanent magnets 14A and 14B. For example, by setting the distance S between the bent portions 16b of the yokes 16A and 16B and the permanent magnets 14A and 14B to be approximately 1.5 times the thickness of the permanent magnets 14A and 14B, the inside of the water pipe 13 can be set. It is possible to prevent the water activating device 1 from becoming unnecessarily large while maximizing the magnetic flux density in the water.

[Experimental Example 2]
In Experimental Example 2, between the surface of the bent portions 16b of the yokes 16A and 16B facing the permanent magnets 14A and 14B and the ends of the permanent magnets 14A and 14B in a direction orthogonal to the facing direction (magnetization direction). The distance S is set to 15 mm (approximately 1.5 times the thickness of the permanent magnets 14A and 14B), the thicknesses t of the yokes 16A and 16B (see FIG. 5) are changed, and the inside of the water passage tube 13 at each thickness. The magnetic flux density was measured.

Specifically, in Experimental Example 2, the thickness t is 2 mm (1/5 of the thickness of the permanent magnets 14A and 14B) to 7 mm (7/10 of the thickness of the permanent magnets 14A and 14B). ), And the magnetic flux density inside the water pipe 13 at each thickness was measured.

FIG. 7 is a graph showing the experimental results of Experimental Example 2. In FIG. 7, the horizontal axis indicates the thickness t (see FIG. 5) (unit: mm) of the yokes 16A and 16B. Further, in FIG. 7, the vertical axis shows the average magnetic flux density (unit: T) which is the average of the values of the magnetic flux densities measured at a plurality of points along the center line of the water pipe 13.

From the experimental results of Experimental Example 2 shown in FIG. 7, the average magnetic flux density (unit: T) is increased by increasing the thickness t (see FIG. 5) of the yokes 16A and 16B, but the thickness t is 4. It was found that the average magnetic flux density did not increase even when the thickness was 5 mm to 5 mm (2/5 to 1/2 of the thickness of the permanent magnets 14A and 14B).

From the experimental results of Experimental Example 2, it is confirmed that the thickness t (see FIG. 5) of the yokes 16A and 16B is preferably set to a dimension of 2/5 to 1/2 of the thickness of the permanent magnets 14A and 14B. did it.

Further, in another experiment, the yokes 16A and 16B were formed of a steel material (SS400), and the same experiment as in Experimental Example 1 was performed, but the experimental results were the same as in Experimental Example 1.
From this experimental result, it was confirmed that the magnetic flux density inside the water pipe 13 did not change regardless of whether the materials of the yokes 16A and 16B were steel (SS400) or pure iron (SUY-1).

From the experimental results of Experimental Example 1 and Experimental Example 2, it was found that the average magnetic flux densities at a plurality of locations along the center line of the water pipe 13 in the water activating device 1 were between 0.25T and 0.35T. ..

<Action and effect of the water activation device 1 of the present embodiment>
In the water activation device 1 of the present embodiment, the distance between both ends of the yokes 16A and 16B and the permanent magnets 14A and 14B in the direction substantially orthogonal to the magnetizing direction of the permanent magnets 14A and 14B is permanent. It is larger than 1/2 times the thickness of the magnets 14A and 14B. Due to the distance between the bent portions 16b of the yokes 16A and 16B and the permanent magnets 14A and 14B, the magnetic flux density is caused by the short circuit of the magnetic circuit from the N pole of the permanent magnet 14A to the S pole of the permanent magnet 14B. Can be prevented from decreasing.

Further, in the water activation device 1 of the present embodiment, in the extending direction (longitudinal direction) of the water pipe 13, a portion 13C having a magnetic action surface on the outside (a portion different from both ends 13A and 13B of the water pipe 13). The wall thickness of the water pipe 13 is thinner than the wall thickness of the water pipe 13 at the portion having the thread (the portion corresponding to both ends 13A and 13B of the water pipe 13). Here, the magnetic flux density is expressed by the product of the strength of the magnetic field and the magnetic permeability. According to the water activation device 1, the magnetic permeability can be increased at a place having a magnetic action surface on the outside (a place different from both ends 13A and 13B of the water pipe 13) as compared with the conventional water pipe. Thereby, even if the strength of the magnetic field is the same, the magnetic flux density acting on the water passing through the water pipe 13 can be increased. Therefore, the magnetic force acting on the water passing through the water pipe 13 can be further increased.

Further, according to the manufacturing method of the water activation device 1 of the present embodiment, the housing body 11 and the lids 12A and 12B are welded and integrated by a laser, so that the central axis of the hollow portion of the housing body 11 is integrated. And the central axis of the water pipe 13 can be aligned with each other. For example, the water activation device 1 of the present embodiment is connected to a water pipe (not shown), buried in the ground, and unbalanced in the housing 10. Even when soil pressure is applied, it is possible to prevent an unbalanced force from being applied to the connection portion between the water activation device 1 and the water pipe, more specifically, the ends 13A and 13B of the water pipe 13. ..

[Experimental Example 3]
In Experimental Example 3, the change in the electromotive force generated in the water pipe when the flow velocity of the water flowing through the water pipe 13 of the water activation device 1 was changed from 0 m / sec to 0.6 m / sec was measured. ..

FIG. 8 is a graph showing the experimental results of Experimental Example 3. In FIG. 8, the horizontal axis indicates the flow velocity (unit: m / sec) of the water flowing through the water pipe 13. Further, in FIG. 8, the vertical axis shows the electromotive force (unit: mV) generated in the water passage pipe.

Here, in the breeding of livestock, it is desirable that the flow velocity of the water flowing through the water pipe 13 when supplying drinking water to the livestock is 0.5 m / sec to 1.0 m / sec.
According to the example shown in FIG. 8, when the flow velocity of the water flowing through the water pipe 13 is 0.5 m / sec, the electromotive force generated in the water pipe is about 130 mV, and the electromotive force increases as the flow velocity increases. You can see that it gets bigger.
Therefore, it can be inferred that the electromotive force at a desirable flow rate (0.5 m / sec to 1.0 m / sec) when supplying drinking water to livestock is between 50 mV and 170 mV.

[Experimental Example 4]
In Experimental Example 4, in the breeding of pigs, which is an example of livestock, the magnetically treated water magnetically treated by the water activation device 1 described above is used as drinking water by a plurality of pigs, and the water is not magnetically treated. The amount of weight gain of each pig was measured when tap water was drunk by multiple pigs as drinking water.
In this experimental result, multiple pigs fed with magnetically treated water had less variation in the amount of weight gain of each pig than multiple pigs fed with unmagnetically treated tap water (of multiple pigs). Of these, the difference in the amount of increase between the pig with the largest increase and the pig with the smallest increase was small). That is, it was found that the plurality of pigs fed with the magnetically treated water gained weight evenly and steadily.

In addition, the sizes of multiple pigs fed with tap water that has not been magnetically treated vary in size, and it is presumed that individual differences in appetite directly affect the size. In addition, it was observed that the pigs fed with tap water that had not been magnetically treated had the food they put in each time, and often slept in the daytime.

On the other hand, multiple pigs that have been made to drink magnetically treated water have increased the amount of drinking water compared to tap water that has not been magnetically treated by drinking water frequently, and they are neatly arranged in size and fleshed out. Immediately after the water was put in, the water was eaten up immediately, and it was observed that there was no water left every time, it was running around even in the daytime, it wanted food, and it squealed well before meals.

From the results of this experiment, it was confirmed that the magnetically treated water magnetically treated by the water activation device 1 promotes the drinking water and food intake of pigs, which are an example of livestock, and contributes to smooth weight gain.

The present invention is not limited to the above-described embodiment, and modifications, improvements, and the like to the extent that the object of the present invention can be achieved are included in the present invention.
