Description

Description: TECHNICAL FIELD The present invention relates to a magnetic treatment device that magnetically improves and purifies water quality of drinking water, industrial water, drainage, agricultural water, and the like.

[Conventional technology]

The water of the drinking water provided for drinking may also contain red rust that is provided from water supply facilities such as pipes and water storage tanks, and so-called rust rust that is transported from the outside. Particularly, when the mixed rust is fine red rust particles, the red rust particles do not easily precipitate and remain suspended in water.
The water in which such red rust particles float is referred to as red water because the particles exhibit a red color. This red water is unsuitable for drinking, and therefore, for example, chemicals are used, mechanical means such as filtration are adopted, or biological means are taken.

However, chemicals are difficult to put into practical use because they may affect the human body after use, as well as animals and plants, and mechanical means increase equipment costs as the amount of treated water increases and are introduced into actual water supply facilities. It never happened. Also, biotechnological tools have not yet been established and are not expected to be adopted at this time. For this reason, recently, a treatment in which water is exposed to a magnetic field, that is, a so-called magnetic treatment has attracted attention.

As an example of the water treatment for performing this magnetic treatment, JP-A-59-59
There is a water treatment device disclosed in Japanese Patent No. 154188. In this water treatment device, a plurality of cylindrical permanent magnets having different poles on an inner peripheral surface and an outer peripheral surface are made non-magnetic in a cylindrical space formed by an inner jacket and an outer jacket made of a non-magnetic material. Different poles are housed side by side through a collar made of a material, and a central member made of a ferromagnetic material and having an outer diameter smaller than the inner diameter of the inner jacket is passed through the central portion of the inner jacket. An inner pipe is formed between the inner jacket and the outer jacket, and an outer pipe made of a ferromagnetic material and having an inner diameter larger than the outer diameter of the outer jacket is concentrically covered with the outer jacket. An outer flow path is formed between the two, and the treated water is circulated through the inner flow path and the outer flow path.

With this configuration, with respect to the inner flow path and the outer flow path, the magnetic flux lines emitted from the cylindrical permanent magnet are crossed,
The effect that the treated water flowing through the inner and outer flow paths can be exposed to the maximum magnetic field is described.

Another known example is a drinking water treatment device disclosed in Japanese Patent Laid-Open No. 61-33290. In this drinking water treatment device, a plurality of axially magnetized hollow disk-shaped permanent magnets are coaxially and closely attached so that the same poles are in contact with each other, and are connected to a hollow cylindrical body, and the hollow portion passes drinking water. The drinking water flow passage is formed with a non-magnetic material.

With this configuration, the magnetic fields are mutually compressed, the magnetic flux density perpendicular to the flow can take a maximum value, and since the fluid passes through the inside of the hollow disk-shaped permanent magnet, the magnetic flux does not expand inside and It describes that the space has an effective magnetic flux density over time, the fluid can be effectively activated, and the reforming function can be exerted without the growth of bacteria such as bacteria.

Further, as another conventional example, magnetic treatment is performed by circulating treated water through a flow path formed of an annular tubular body formed between an inner tube connected to different poles of a permanent magnet and an outer tube surrounding the outer side thereof. There is a water treatment device that does. In this water treatment device, the inner pipe and the outer pipe are formed close to each other on one end side of the flow path to form a gear tap, a high magnetic flux density is generated in the gear tap portion, and a magnetic flux is applied to the treated water when passing through the gear tap portion. It is set to be processed.

[Problems to be Solved by the Invention]

By the way, it has been experimentally proved that the magnetic flux density required for the magnetic treatment varies depending on the use and purpose. That is, magnetic treatment with a magnetic flux density of 1000 gauss to 1500 gauss is effective for promoting the growth of plants containing fungi, and at least 5000 is effective for removing red rust and scale.
The effect is recognized in the magnetic treatment under the magnetic flux density of Gauss or higher.

However, in the first water treatment device, magnetic flux lines are generated between the permanent magnet of the inner N pole and the outer S pole and the permanent magnet of the inner S pole and the outer N pole that are adjacent in the axial direction, The magnetic flux lines will cross the entire circular cross section of the inner and outer flow paths, but the distance between the different poles will be longer, so the magnetic flux density will be smaller, and a maximum magnetic flux density of about 2000 gauss will be obtained. I can't. Further, generally, when the flow path cross-sectional area is reduced, the magnetic flux density increases, but there is a problem that the required processing flow rate cannot be obtained.

Further, in the drinking water treatment device mentioned second, since the same poles are connected so as to be in contact with each other and the repulsive magnetic field is used, there are continuous contradictory compressed magnetic fields. The magnetic flux density is small. Therefore, the effect of removing red rust and scale cannot be obtained. Also, it is demagnetized due to the repulsive magnetic field and is not suitable for long-term use.

Further, in the third water treatment device, the magnetic treatment is performed when the water passes through the gear portion, but since it is instantaneous, it cannot be said that the magnetic treatment is sufficiently performed. Also, since the flow passage area becomes smaller and the flow passage resistance becomes larger at the gear part,
There is a problem that it is difficult to secure a desired flow rate.

The present invention has been made in view of the technical background as described above, and an object thereof is to obtain a large amount of processing fluid at one time with a high magnetic flux density of 5000 gauss or more, preferably 7000 gauss or more. It is to provide a processing device.

[Means for Solving the Problems]

In order to achieve the above object, according to the present invention, in a magnetic processing apparatus which is arranged in a fluid path and introduces a fluid to be processed into a magnetic field to perform magnetic processing, an inner peripheral surface and an outer peripheral surface are formed with different polarities. A permanent magnet array formed by stacking a plurality of conical cylindrical permanent magnets with different poles facing each other at predetermined intervals via a spacing control means made of a non-magnetic material, and a non-permanent magnet housing the permanent magnet array. One end of the permanent magnet row in which a casing made of a magnetic material, a fluid flow path formed between the outer peripheral side of the permanent magnet row and the inner surface of the casing, and a through hole at the center of each permanent magnet are arranged in series. The introduction path that supplies the same fluid to the through hole portion on the side and the other end side of the through hole portion that impedes the flow passing through the through hole portion, and at least most of the fluid introduced into the through hole portion From the gap between adjacent permanent magnets to the outside of the permanent magnet And flow restriction means for outflow direction,
And a lead-out path for leading the fluid, which is regulated by the flow regulating means and flows out of the permanent magnet array, to the outside of the casing.

[Action]

According to the above means, when the spacing between the permanent magnets is set to 1 mm to 2 mm, for example, a magnetic flux density of about 6000 gauss to 7,000 gauss can be easily obtained with a permanent magnet having an energy product of about 10800 gauss. When the fluid is introduced into the through hole in the center and the flow restricting means changes the flow direction of the fluid so that at least most of the fluid flows out along the gap between the permanent magnets in the outer peripheral direction of the permanent magnet, It becomes possible to perform magnetic treatment by exposing it to a magnetic flux density. Also, since the total opening area of the gap between the permanent magnets is the flow path area, by matching the statistics of the opening area with the cross-sectional area of the introduction path, a large amount of magnetic processing can be performed without increasing the flow path resistance. You can do it. Thereby, for example, the red rust particles existing in the treated water are sufficiently magnetized, adsorbed to each other while floating and precipitated as a combined body, and the treated water can be cleaned.

At this time, each permanent magnet is formed in a conical cylinder shape, and the treated water is discharged along the inclination of the side surface of the conical cylinder body, so that the pressure loss is reduced, the treatment efficiency is improved, and a large amount of treated water is obtained. Magnetic processing becomes possible.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 are for explaining a water treatment device as a magnetic treatment device according to an embodiment. FIG. 1 is a partially cutaway perspective view of the water treatment device, and FIG. 2 is a permanent magnet array. And FIG. 3 is an explanatory view showing the flow of treated water.

In FIG. 1, the water treatment device 10 includes a plurality of permanent magnets 1.
The permanent magnet array 13 is composed of one laminated body, and the casing 15 that houses the permanent magnet array 13 is mainly configured.

The permanent magnet 11 is a conical tubular plate having a through hole 17 in the center thereof, and as shown in FIGS. 2 and 3, both the inner peripheral surface and the outer peripheral surface are magnetized into N pole and S pole, respectively. ing. The permanent magnet 11 is a samarium-cobalt magnet and is magnetized to have an energy product of 10800 gauss. And
As shown in FIG. 1, six such permanent magnets 11 are laminated so that different poles face each other with the upper through hole 17 being coaxial, and a permanent magnet array 13 is formed. This laminated body is laminated through a holder 19 which is fitted to the outer peripheral portion of each permanent magnet 11 and is made of polycarbonate, for example. The spacer portion 21 projecting in the direction and the projecting portion 23 projecting in the outer peripheral direction as the treated water circulation path forming means are integrally formed in a ring shape. Then, by changing the plate thickness of the spacer portion 21, the interval w between the adjacent permanent magnets 11 can be freely set. In the case of this embodiment, the interval w is set to 3.0 mm in consideration of the magnetic flux density and the flow passage area. This distance is optimally between 1 mm and 5 mm. Considering the magnetic flux density, 1.0 mm or less is more advantageous, but the permanent magnet 1
As the suction force of 1 becomes too strong, it is not only technically difficult to assemble, but it may also be clogged with dust and rust in the treated water. If it is 5.0 mm or more, 2000 gauss or less Therefore, it is not practical because the required magnetic flux density cannot be obtained. Further, the interval w can be freely set by changing the plate thickness of the spacer portion 21 as described above, and therefore, the magnetic flux density required for the target treated water and the permanent magnets 11 of the permanent magnet row 13 are required. It is also possible to adjust the number of sheets to secure the required flow rate.

In this way, the permanent magnet rows 13 formed by stacking via the holder 19 can be integrally handled by mutual attraction force without providing a fixing tool, but if necessary,
A through hole may be formed in the protrusion 23 and fixed by a bolt and a nut.

The casing 15 is composed of a cylindrical cover pipe 25, a treated water introduction side flange 27 and a treated water discharge side flange 29, and has screw portions 31, 33 screwed to the outer circumferences of both flanges 27, 29. The three parts are integrated by screwing together screw parts 35 and 37 screwed on the inner circumference of the cover pipe 25. At this time, the packing 39 is sandwiched between the end surface of the cover pipe 25 and the end surface of each flange, and
15 has a watertight structure.

Further, the treated water introduction side flange 27 has an introduction path 4 for introducing the treated water from the outside of the casing to the inside of the casing.
1 is formed coaxially with the through hole portion 18 formed of the through holes 17 arranged in series, and the flange 29 on the treated water outlet side has a lead-out path 43 for leading the treated water out of the casing into the casing. It is formed coaxially with the portion 18. These flanges 27 and 29 are made of magnetic soft iron, respectively, and a connecting member 46, to which a pipe screw 45 is screwed if necessary, is welded to the outer peripheral portions of the path portions 42 and 44 protruding from the flange portions, and this connection is made. It is connected to the flowing water path outside the water treatment device 10 via the member 46.

The cover pipe 25 is made of transparent polycarbonate in this embodiment, and the inner diameter thereof is set to a size such that the projecting portion 23 of the holder 19 can be inserted therein. Thereby, when the permanent magnet array 13 is inserted into the casing 15, a treated water circulation path 47 is formed between the inner surface of the cover pipe 25 and the outer peripheral portion of the holder 19 other than the protruding portion 23 of the holder 19. . Further, since the cover pipe 25 is transparent, the gap 14 between the permanent magnets 11 and the treated water flow path 47 can be visually recognized from the outside.

Further, a water stop member 51 made of magnetic soft iron is attached to the inner surface 49 of the permanent magnet row 13 on the side of the lead-out flange 29 so as to close the through hole portion 18. The water stop member 51 is formed in a shape that closes only the through hole portion 18 and does not close the treated water flow passage 47. In this embodiment, the water stopper member 51 corresponds to the protruding portion 23 of the holder 19. The part extends in the outer circumferential direction, and the end surface of the lead-out side flange 29 is brought into contact with and pressed by the end surface. However, for example, as described above, through holes are formed at positions corresponding to the through holes that are inserted through the protrusions 23 of the holder 19, and these holders 19 are integrally fixed to the permanent magnet array 13 via bolts and nuts. May be.

This water treatment device 10 is, for example, as shown in FIG. 4, a discharge end of a water supply pipe 57 of a water tank 55 of a building and a drain pipe 59.
It is used by being screwed to the suction end of the above through the connecting member 46 and connected. In the case of this example, the water treatment device 10 attached to the water supply pipe 57 side is mainly for treating rust from the water main, and the water treatment device 10 attached to the drain pipe 59 side is a water tank. This is for treating red rust in the drain pipe and the inner wall of the drain pipe, which is guided from 55 to each water supply point in the building.

This will be specifically described.

That is, when tap water mixed with red rust is supplied from the water main to the water storage tank 55 side through the water supply pipe 57, the tap water flows from the introduction path 41 of the flange 27 to the through hole portion of the permanent magnet array 11. Guided to 18. However, since the through hole portion 18 is closed by the water stop member 51 on the side of the lead-out side flange 29, all the tap water introduced is in each permanent magnet 1.
It flows out along the gap 14 between the magnets 1 toward the outer circumference of the permanent magnet 11. At this time, as shown in FIGS. 2 and 3, since the end faces of the adjacent permanent magnets 11 are formed to have different polarities, tap water passing through the gap 14 has at least 50
Over 00 gauss, mostly 6000 gauss or 7000
It is exposed to a Gaussian magnetic flux density. That is,
The gap 14 functions as a magnetic treatment path, and magnetic treatment is performed in the gap 14.

Then, the magnetically treated tap water reaches the treated water flow passage 47 formed between the outer peripheral portion of the holder 19 fitted on the outer periphery of the permanent magnet 11 and the inner surface of the cover pipe 25, and the cover pipe 25 Along the inner surface of the water outlet, the water flows out in the long axis direction, passes outside the outer peripheral surface of the water stop member 51, gathers in the derivation path 43, and is discharged from the derivation path 43 into the water tank 55.
The water flow in the water treatment device 10 at this time is shown in FIGS.
In the figure, it is indicated by a symbol F.

In the tap water magnetically treated in this manner, the red rust mixed in the tap water is reduced to black rust particles 61, and the magnetized black rust particles 61 aggregate in the water storage 56 and settle in the water storage tank 55. The water, which is extremely transparent, is supplied to various parts of the building through the drain pipe 59. More specifically,
Subject of rust is thought to iron oxide F _e2 O ₃ of the III, which is reduced, is considered to be the F _e3 O ₄ and F _{e O.} Both F _e3 O ₄ and F _e O are black rust, which means that they are reduced from III valence to II valence. And even though red rust does not contain a ferromagnetic substance, black rust contains a large amount of ferromagnetic substance, so when black rust is magnetized, it aggregates and precipitates. The occurrence will be suppressed. The black rust that has aggregated and precipitated may be removed using another permanent magnet or the like, for example, during monthly building maintenance.

The water treatment device 10 attached to the drain pipe 59 side further magnetically treats the magnetically treated water in the water storage tank 55. By this magnetic treatment, the inner wall of the pipe from the drain pipe 59 to each water supply point is It is possible to remove the red rust that has occurred in the. This is because the red rust on the inner wall of the pipe is reduced by nascent hydrogen in the magnetically treated tap water, the surface gradually becomes black rust, and this black rust separates from the red rust and flows out. Is believed to be.

Therefore, the water treatment device 10 is connected to the water supply pipe 57 as described above.
If it is attached to the discharge end of the pipe and the suction end of the drain pipe 59, not only can red water be prevented, but also red rust of the pipe in the building can be removed.

In addition, although the above-described embodiment describes the removal of red rust, it is also possible to remove the hardly soluble scale attached to the inner wall of the pipe. In this case, the sparingly soluble scale is reduced and removed to change into a soluble scale, which is dissolved in tap water and discharged.

Further, in the above-mentioned embodiment, both are constituted so that the flow restricting means is constituted by the blind plates 51, and all the treated water introduced is guided to the gaps 14 between the permanent magnets 11 and magnetically treated in the gaps 14, etc. However, when the magnetic flux density for magnetizing may be low, a small amount of water may be directly led from the flow restricting means to the side of the lead-out path 43.

As described above, according to the above embodiment, the permanent magnet 11 in which both side surfaces of the conical cylindrical body are magnetized is used.
Are stacked so that the different poles face each other at a short distance via the spacer portion 21 of the holder 19, so that the permanent magnet 11 having an energy product of about 10800 gauss and the gap 14 serving as the magnetic action path has 6000. Gauss or 700
It is possible to obtain a magnetic flux density of 0 Gauss or more. As described above, since a magnetic flux density of at least 5000 Gauss can be obtained, a strong magnetizing action can be exerted and the generation of red water can be easily prevented. For the reason, it is possible to effectively remove red rust and scale on the inner wall of the pipe, and to adjust the gap 14 between the adjacent permanent magnets 11 and the number of stages (number of sheets) of the permanent magnets 11 with respect to the area of the through hole 17. By this, the flow passage area can be made equal, and the treated water introduced from the introduction passage 41 is led out along the side surface of the conical tubular body having an inclination at an acute angle with respect to the flow direction, thus increasing the flow passage resistance. It is possible to magnetically process a large amount of treated water without having to do so. Since the interval w between the permanent magnets 11 can be freely set by the thickness of the spacer portion 21 of the holder 19,
For example, a magnetic flux density of about 1,500 gauss, which is suitable for growing plants, can be obtained with the same configuration, and the cover pipe 25 is formed transparently regardless of the applicable magnetic treatment field, so that the gap 14 is not visible. A spacer as an interval regulating means, which can be processed before clogging, and is magnetically processed while flowing out in the outer peripheral direction of the permanent magnet 11, so that it is exposed to a magnetic field for a long time and sufficient magnetization is possible. Since the portion 21 and the projecting portion 23 as the treated water flow path forming means are integrally formed with the holder 19 fitted to the outer peripheral portion of the permanent magnet 11, various effects such as easy assembling and the like can be obtained. is there.

Incidentally, water that has been magnetically treated to date, that is, magnetically treated water, in addition to the control of the above-mentioned red rust and scale, the removing effect and the plant growth promoting effect, the precipitation effect of suspended solid fine particles, the performance improving effect of concrete, It is needless to say that the effect of improving the fuel consumption of liquid fuel and the like are known, and that the magnetic treatment device according to the present invention exerts effects on all of them. In particular, since a magnetic processing device having a magnetic flux density of 5000 gauss or more has not been put into practical use until now, it is possible to exert a sufficient effect even on an object which has been considered to be insignificant.

〔The invention's effect〕

As is clear from the above description, the magnetic processing device of the present invention performs magnetic processing by causing the gap of the permanent magnets laminated via the space regulation means to serve as a magnetic action path and flowing out from the central portion of the permanent magnet to the outer peripheral portion. According to this, since the different poles of the permanent magnet, which are formed of a conical cylindrical body whose inner and outer peripheral surfaces have different polarities, are opposed to each other at a short distance, a high magnetic flux density can be obtained. At this time, since it is not necessary to reduce the flow passage area for the magnetic treatment, and since the flow passage direction has an acute inclination, the flow passage resistance is reduced, and the efficiency of a large amount of fluid is improved. Magnetic processing becomes possible.
