[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid ionization apparatus using a magnet for activating a fluid in a fluid flow pipe.

[0002]

2. Description of the Related Art Conventionally, as a fluid ionization apparatus using a magnet, a tip constituting a magnetic pole is directed inward with respect to a hollow fluid distribution pipe with respect to the pipe, and the tips of adjacent magnets have different magnetic poles. There is a type in which a magnetic field is formed between the magnetic poles and at least a pair of magnets are arranged so that the direction of the magnetic field lines of the magnetic field is substantially perpendicular to the axis of the pipe, and the fluid lines in the pipe are ionized by the magnetic field lines.

[0004]

However, the fluid ionizer requires a plurality of magnets, so that the cost is high, and although the magnetic flux density is increased by the concentrator, the concentrator is attached to the tip of the magnet. Therefore, the effect of concentrating and increasing the magnetic flux density is relatively small, about twice as large as when the concentrator is not attached, and the magnetic flux density of the magnet itself is reduced to a predetermined magnetic flux density (the magnetic flux between the concentrators required for the fluid ionizer). Density) to some extent.

[0005] In order to manufacture a fluid ionizer having a higher fluid ionization efficiency, it is necessary to use a magnet having a higher magnetic flux density. However, a magnet having a higher magnetic flux density is usually large in size. However, in order to reduce the size of the device, it is necessary to provide a relatively small magnet with a relatively high magnetic flux density as described above. There was a problem that the cost was high.

1 to 3 show one embodiment of the present invention. FIGS. 1 (a) and 1 (b) show a fluid ionization apparatus 1 equipped with a magnet and a fluid distribution pipe 2 such as a water pipe. Is attached to the outer circumference of the pipe and is fixed with a so-called insullock tie 3, which is a binding band including a string and the like, whereby the water flow S in the pipe 2 passes through the magnetic field to activate water. To prevent scale adhesion, corrosion and algae generation in the pipe 2.

As shown in FIGS. 2 and 3, the fluid ionizer 1 has a block-shaped magnet 6 whose opposite side surfaces 6a and 6b form mutually different magnetic poles, and a pair of opposite side surfaces 6a and 6b of the magnet 6. It is composed of a pair of concentrators 7 mounted to concentrate magnetic flux density, a case 8 holding a unit 5 in which the magnet 6 and the concentrator 7 are integrated, and the unit 5 and the case 8 are integrally fixed. It has a structure.

In the present embodiment, the magnet 6 has an outer shape of 10 ×
It is made of a neodymium alloy that is 51 × 55 (mm) and has a substantially rectangular parallelepiped shape having a height direction of 51 mm. Different magnetic poles (S pole or N pole)
And the magnetic flux density of the left and right side surfaces 6a, 6b is approximately 220
The magnetic flux density of about 0 Gauss and the upper end face 6c and the lower end face 6b are set to about 4000 Gauss.

On the other hand, the concentrator 7 is formed of a magnetic material, and the right and left side surfaces 6 of the magnet 6 are formed.
a, 6b, which are detachably mounted by magnetic force and are integrated with the magnet 6, but the concentrator 7 has a notch capable of closely contacting a part of the upper end surface 6c and the side surface 6a or 6b of the magnet 6. Shaped holding portion 7a is formed,
The concentrator 7 clamps the magnet 6 from the left and right side surfaces 6a, 6b of the magnet 6 so that the magnet 6 is accommodated in the space formed by both holding portions 7a of the left and right concentrators 7 facing each other. Note that both side surfaces 6a and 6b of the magnet 6 are covered with a plurality (two in this embodiment) of concentrators 7, respectively.

At this time, the upper surface (upper surface) 7b of each concentrator 7 protrudes above the upper surface 6c of the magnet 6, but the upper surface 7b, which is the adjacent surface of the left and right concentrators 7, is located on the inner side. (The magnet 6 side) to form a valley-like inclined surface, and the left and right upper end surfaces 7b are opposed to each other in an inclined state, and serve as contact surfaces that come into contact with the outer peripheral surface of the pipe 2 together. ing. Each upper end surface 7
A close gap is formed between the lower ends of b and 7b.

The corresponding contact surface (upper surface) 7b and the pipe 2
A magnetic field is formed such that the direction of the line of magnetic force a between the left and right contact surfaces 7b is substantially perpendicular to the axis c of the pipe 2 in the contact state with the pipe 2. The left and right contact surfaces 7b are continuously formed into a concave shape so as to form a single arcuate surface, and the outer ends of the contact surfaces 7b are chamfered.

Thus, the contact surface 7 of the concentrator 7
The magnetic flux is concentrated between the contact surfaces 7b and the magnetic flux density between the corresponding contact surfaces 7b is equal to the magnetic flux density of the upper end surface 6c of the magnet 6 alone (40%).
00 Gauss), about 3.5 times, about 1400
It is concentrated on 0 Gauss and raised. In particular, since the contact surface follows the outer periphery of the pipe 2 in a concave shape, the effect of concentrating the magnetic flux density is further enhanced.

On the other hand, the above-mentioned case 8 is arranged such that the unit 5 composed of the magnet 6 and the concentrator 7 integrated by the magnetic force as described above is on the side opposite to the contact surface 7b on the opposite contact surface (bottom surface 5a). The case 8 has a box shape that can be inserted and removed freely. The front and rear surfaces 8a and 8b of the case 8 hold the front and rear surfaces 7c and 7d of the concentrator 7 and the rivet 9 is moved from the front surface 8a of the case 8 The case 8 and the concentrator 7 are integrally fixed by rivets 9 so as to penetrate the concentrator 7 and protrude from the rear surface 8 b of the case 8.

As a result, the unit 5 is held in the case 8 and is integrally fixed to the case 8 so that the fluid ionization apparatus 1
Is configured. A flange 11 protrudes from left and right side surfaces 8c and 8d, which are opposite side surfaces of the case 8, and the fluid ionizer 1 (case 8) and the pipe 2 are fixedly fixed to the flange 11 as described later. A plurality of holes 12 are formed as accommodation portions for positioning and accommodating and inserting a band-shaped binding band (in the present embodiment, the insulated tie 3) including a string.

The fluid ionization apparatus 1 of the present embodiment configured as described above is used by being attached to the pipe 2 so that the outer peripheral surface of the pipe 2 is brought into contact with the contact surface 7b. When the pipe 2 is made of a magnetizable metal, the pipe 2 is magnetized by the concentrator 7 (contact surface 7b), and the pipe 2 and the fluid ionizer 1 are detachably fixed by magnetic force.

When the pipe 2 is made of a material (plastic or the like) which cannot be magnetized due to non-ferrous material or the like, the insulating tie 3 is inserted through the hole 12 formed in the case 8 (flange 11). At least, by turning the outer circumference of the pipe 2 and the outer circumference of the case 8 to fasten them,
The fluid ionizer 1 is attached to and fixed to the pipe 2.
Note that, even when the pipe 2 is made of a magnetizable metal, the above-described fixing method using the insulator lock 3 may be used together with the fixing by the magnetic force.

As a result, the magnetic flux density in the magnetic field between the left and right contact surfaces 7b forms a strong magnetic field with a higher density in the pipe 2 without being diffused. It is almost right angle and is always cut to the maximum by the movement of water to generate the most efficient and maximum current. Therefore, a relatively strong current flows between the water and the pipe 2 to give the pipe 2 a sufficient negative charge.

Particularly when a metal pipe is used, the pipe 2 having a negative charge removes all anions such as carbonate and oxygen, so that deposits and corrosion can be prevented. Furthermore, since a positively charged surface is required for the algae to adhere, the algae do not adhere to the negatively charged pipe 2, and as a result, the pipe 2 is kept clean, and the flow rate and the strength of the pipe 2 are maintained. Is kept.

Even if scale, corrosion, and algae have already adhered to the pipe 2, these harmful substances can be removed by attaching the fluid ionizer 1 to the pipe 2 as described above. That is, by attaching the fluid ionizer 1 to the pipe 2 as shown above, the hydrogen 2 in the water is combined with the negative calcite deposit by the negatively charged pipe 2, and the calcite deposit is combined with calcium bicarbonate. Dissolves in water and is carried away by water streams. Thus, the scale is removed and no deposits are generated.

Further, by means of the negatively charged pipe 2,
The hydrogen in the water combines with the iron oxide (if the pipe 2 is iron) or rust, and the corrosion dissolves in the water and iron and is carried away by the water stream. Since the positively charged water and the negatively charged pipe 2 hinder the cell division of the algae, the attached algae are prevented from keeping the sludge layer and continuing to grow. The algae therefore die rapidly, are carried away by the water stream, and further algae deposition and growth are prevented by the negatively charged pipe 2.

At this time, in the case of the present embodiment, since the concentrator 7 is closely attached to both side surfaces 6a and 6b of one magnet 6, the concentrator 7 is attached so as to cover the magnet 6 from both side surfaces 6a and 6b. The magnetic flux density between the two contact surfaces 7b of the concentrator 7 is increased as compared with the magnetic flux density of the magnet 6 alone, and the effect of increasing the magnetic flux density is particularly high as compared with the case where the concentrator is attached to the tip of the magnet. A strong magnetic field is formed between the contact surfaces 7b.

Since the pipe 2 is disposed in the strong magnetic field, the performance of cleaning the pipe 2 and removing scale and the like can be improved without increasing the magnetic flux density of the magnet 6 more than necessary. it can. For this reason, in configuring the fluid ionization apparatus 1, it is not necessary to increase the magnetic flux density of the magnet 6 more than necessary, so that it is not necessary to increase the magnet 6 more than necessary, and one magnet 6 is sufficient. Therefore, the fluid ionization apparatus 1 can be simply configured, and can be downsized, the manufacturing cost can be reduced, and the cost can be reduced.

Further, a flange 11 is provided on the case 8, and the fluid ionizer 1 and the pipe 2 are fixed with the use of the flange 11 by an insulator 3 or the like, so that the fluid ionizer 1 is formed of a material that cannot be magnetized. Pipe 2
It can also be easily attached to a non-magnetic pipe, and the removal of scale and the like can be easily performed. In this case, since the fluid ionization device 1 is not unnecessarily large, the mounting is easy and the degree of freedom of the mounting location is high.

Further, since the contact surface 7b is depressed in a concave shape and a single arc-shaped surface is formed by the left and right contact surfaces 7b, the contact surface follows the outer periphery of the pipe (along the pipe). The magnetic flux concentration inside works effectively, and the fluid ionizer 1 is stably mounted (contacted) by the pipe 2.

4 to 6 show another embodiment of the present invention. FIGS. 4 (a) and 4 (b) show magnets 6 as in the above embodiment.
Is installed around a fluid distribution pipe 2 such as a water pipe, and a binding band (Insulok 3) is installed.
The water flow s in the pipe 2 passes through the magnetic field to activate the water, thereby preventing scale adhesion, corrosion, and generation of algae in the pipe 2. .

The fluid ionizer 1 has a plate-shaped magnet 16 as shown in FIGS. 4 to 6, and a concentrator 17 for holding the magnet 16 from the left and right side surfaces 16b and 16c to increase the magnetic flux density as described later. It is constituted by a case 18 and the like holding a unit 15 in which a magnet 16 and a concentrator 17 are integrated, and has a structure in which the unit 15 and the magnet 16 are integrally fixed.

In this embodiment, the magnet 16 has an outer shape of 10
7.5 × 6.5 × 1 on the front and back of a substantially rectangular parallelepiped with a height of 24.5 mm × 24.5 × 27 mm.
It is made of a neodymium alloy having a notch of 0 mm (7.5 in the height direction) and having a convex shape in a side view.
b, 16c and different magnetic poles (S-pole or N-pole), the magnetic flux density on the left and right side surfaces is approximately 2500 gauss, and the magnetic flux density on the upper end surface 16d (the upper end surface of the protrusion 16c) is approximately 3500 gauss. It is set to a degree.

On the other hand, the concentrator 17 is formed of a magnetic material, and the right and left side surfaces 16 of the magnet 16 are formed.
b, 16c are detachably attached by magnetic force,
The left and right side surfaces 16b and 16c of the magnet 16 are covered by one concentrator 17, and the concentrator 17 is also convex like the magnet 16 in the side view (the magnet 1 in the side view).
6).

The concentrator 17 is formed with a notch-like holding portion 17a which can be in contact with a part of the upper end surface 16d of the magnet 16 and the side surfaces 16b, 16c. The concentrator 17 holds the magnet 6 from the left and right side surfaces 6a and 6b of the magnet 6 so that the magnet 16 is accommodated in the space defined by 17a.

At this time, the upper surface (upper surface) 17b of each concentrator 17 protrudes above the upper surface 16d of the magnet 16, but the upper surfaces 17b, which are the mutually adjacent surfaces of the left and right concentrators 17, are inward. (The magnet 16 side) to form a valley-shaped inclined surface, and the left and right upper end surfaces 17b are opposed to each other in an inclined state, and serve as contact surfaces that come into contact with the outer peripheral surface of the pipe 2 together. ing. The corresponding contact surface (upper surface) 17b and the pipe 2
Line of magnetic force a between the left and right contact surfaces 17b in the contact state with
The magnetic field is formed such that the direction is substantially perpendicular to the axis c of the pipe 2.

Although the magnet 16 and the concentrator 17 are formed in a convex shape as described above, the magnet 16 and the concentrator 17 are substantially perpendicular to the direction of the magnetic force line a between the two contact surfaces 17b.
The width L1 (15 mm) of the concentrator 17 before and after the contact surface 17a is equal to the width L2 (27 m) of the opposite contact surface.
m).

The left and right contact surfaces 17b are continuously formed into a concave shape so as to form a single arcuate surface, and the outer end of the contact surface 7b is chamfered. As a result, the magnetic flux is concentrated between the contact surfaces 17b of the concentrator 17, and the magnetic flux density between the contact surfaces 17b is approximately 3.3 times the magnetic flux density (3500 gauss) of the upper end surface 16d of the magnet 16 alone. The degree is concentrated around 11500 gauss and raised.

On the other hand, the above-mentioned case 18 moves the unit 15 composed of the magnet 16 and the concentrator 17 integrated by magnetic force as described above to the opposite contact surface (bottom surface 15a) which is the surface opposite to the contact surface 17b. And the front and rear surfaces 17 c, 17 of the concentrator 17.
It is constituted by a substantially U-shaped plate capable of covering the lower side of d.

The front and rear surfaces 18a, 18b of the case 18
The front and rear surfaces 17c and 17d of the concentrator 17 (integral with the magnet 16) are held by the
8, the concentrator 17 is penetrated from the front surface 18 a, and protrudes from the rear surface 18 b of the case 18.
And the concentrator 17 are integrally fixed, and the fluid ionization apparatus 1 in which the unit 15 is held in the case 18 is configured.

At this time, between the bottom surface 15a of the unit 15 and the inner surface of the bottom surface 18c of the case 18 opposed to the bottom surface 15a, an insulation lock tie 3 for fastening and fixing the unit 15 and the pipe 2 as described later is provided. A predetermined gap 21 serving as an insertion portion to be inserted is formed.

The fluid ionization apparatus 1 of the present embodiment configured as described above is also used by being attached to the pipe 2 so that the outer peripheral surface of the pipe 2 is brought into contact with the contact surface 17b.
At this time, if the pipe 2 is made of a magnetizable metal, the pipe 2 is magnetized by the concentrator 17 (the contact surface 17b), and the pipe 2 and the fluid ionizer 1 are detachably fixed by magnetic force.

When the pipe 2 is made of a non-magnetizable material (plastic or the like) made of non-ferrous material or the like, the insulating tie 3 is inserted through the gap 21 between the case 18 and the unit 15. The fluid ionizer 1 is attached and fixed to the pipe 2 by rotating and fixing the outer circumference of the unit 15 and the bottom surface 15a of the unit 15. Note that, even when the pipe 2 is made of a magnetizable metal, the above-described fixing method using the insulator lock 3 may be used together with the fixing by the magnetic force.

Thus, the fluid ionization apparatus 1 having the above structure
In the same manner as in the above-described embodiment, the inside of the pipe 2 can be cleaned, scale, and the like can be removed. Since the front-rear width is narrower than the front-rear width L2 of the (non-contact surface side) {the width is reduced by (L2−L1) / 2}, the magnetic field generated on the front-rear surface side is weakened and the contact is made. The magnetic flux is more concentrated between the surfaces 17b, and the contact surface 17b
Even when the magnetic flux density is relatively concentrated between the magnets 16 and the size of the magnet 16 is small, a relatively high effect can be obtained.

Therefore, the fluid ionization apparatus 1 can be further miniaturized. However, since there is no need to particularly provide a flange or the like on the case 18, no protrusion projects from the fluid ionization apparatus 1 and the fluid ionization apparatus 1 The degree of freedom of the mounting location is higher, but especially the concentrator 1
Since the front and rear of 7 are notched, the screws and the like do not hinder the mounting, the projections and the like do not interfere, and the fluid ionization apparatus can be used for pipes and various pipes in narrow places. 1 can be mounted more easily.
The insertion portion may be formed by a band pass (not shown) projecting from the outer surface of the bottom surface 18c of the case 18.

Although the above description has been made only for the case where water is simply circulated in the pipe 2, the present invention relates to pipes for crude oil, natural gas, gasoline, diesel and fuel oil, cooling, heating, cooking and washing. It can be applied to any pipe for conveying fluid, including irrigation, swimming pool, spring water and drinking water pipe. If the fluid is not a conductor such as water, no current is generated when passing through the magnetic field lines, but it is possible to impart a negative charge to give the molecule activity.

There is no need for recurring costs or conventional pipe processing using expensive toxic chemicals. Very high efficiency can be achieved with a small number of magnets. Because the device is very small, multiple devices can be installed on the same cross section of the pipe to achieve a higher effect. It is easily mounted magnetically on steel pipes, while it can be easily adjusted to fit pipes of various diameters. It can also be used to protect non-metallic or non-ferrous pipes, as already exemplified.

[0048]

According to the structure of the present invention constructed as described above, the concentrators are attached to the opposing side surfaces of the block-shaped or plate-shaped magnet, and the flow of the fluid flows between the adjacent end surfaces of the opposing concentrators. By concentrating the magnetic flux between the concave surfaces along the outer peripheral surface of the pipe and forming the magnetic field so that the direction of the lines of magnetic force intersects the axis of the pipe, the magnetic flux density between the concave surfaces can be increased. , A strong magnetic field is formed. As a result, a more effective fluid ionizer can be formed.

For this reason, in configuring the fluid ionization apparatus, it is not necessary to increase the magnetic flux density of the magnet more than necessary. Therefore, it is not necessary to increase the magnet itself more than necessary. The ionization device can be simply configured, and can be reduced in size. Further, the manufacturing cost can be reduced and the cost can be reduced.

Particularly, the width of the magnet and the concentrator in the front-rear direction on the upper end face is formed shorter than the lower end face .
Cut the front and back of the end of the concentrator
The Rukoto to form the end portion by depressing the lack shape convex direction of the magnetic field formed substantially perpendicular to the magnetic lines between the abutment surface is made to decrease, converging effect of the magnetic flux is compared to the size or the magnetic force of the magnet And the fluid ionizer can be made smaller, and the degree of freedom for mounting is increased.
Also, there is an advantage that attachment to the pipe 2 having projections or the like is facilitated .

Further, by making the contact surface of the concentrator a valley-shaped inclined surface, the pipe can be more stably supported and contacted, but the concave surface is formed as a single arc-shaped surface. By forming it in a concave shape, the concave surface follows the pipe, and the pipe can be more reliably supported, and the lines of magnetic force can be concentrated on the pipe side, so that the magnetic flux can be more concentrated.

Further, by providing a case for integrally fixing the unit in which the concentrator and the magnet are integrated, the fluid ionizer can be easily handled. However, flanges are protrudingly provided on opposite sides of the case.
The flange is provided with a receiving portion for positioning and holding a binding band for fastening and fixing the case side and the pipe, or an insertion portion for inserting a binding band for fastening and fixing the case side and the pipe on the bottom side of the case. By tightening, the binding band is inserted through the housing portion or the insertion portion, and the pipe and the fluid ionization device are fastened and fixed, so that the fluid ionization device is made of a non-ferrous material or the like and is made of a non-magnetizable pipe (such as plastic). There is also an advantage that it can be attached to the.

Since the insertion portion is formed by a gap formed between the bottom surface of the unit and the bottom surface of the case, it is not necessary to project the projection from the fluid ionizer, and the fluid ionizer can be further miniaturized. It is possible,
The degree of freedom of the mounting location of the fluid ionization device is increased, and the fluid ionization device can be easily mounted on a pipe or the like located in a narrower place.
