Description

  The present invention is, for example, water removal system, hot water supply system, various cooling water systems, air conditioning cold / hot water system, etc., for all pipes targeting various liquids, rust removal, corrosion prevention, removal of various scales (calcium carbonate, silicon compounds, etc.) and The present invention relates to a magnetic processing apparatus having excellent magnetic characteristics for preventing adhesion.

  Liquids (e.g., water) that flow in piping such as water supply systems, hot water supply systems, various cooling water systems, and air conditioning cold / hot water systems include various components such as calcium ions, chloride ions, sulfate ions, and carbon dioxide. This causes troubles such as red rust and scale deposition. Thus, as a technique for removing such a failure, for example, an apparatus as shown in Patent Document 1 has been proposed. In such a device, a plurality of permanent magnets are arranged opposite to each other on the outside of the water supply pipe, and a magnetic treatment is performed on the liquid (water) flowing in the water supply pipe by the plurality of permanent magnets.

  By the way, in order to effectively apply the magnetic force of the permanent magnet to the liquid (water) as it is, it is preferable that no obstacle is interposed between the permanent magnets. However, in the conventional apparatus, since the water supply pipe is interposed between the permanent magnets, the magnetic force of the permanent magnet is reduced by the water supply pipe. In this case, a high magnetic force cannot be applied uniformly and uniformly to the entire liquid (water) flowing in the water supply pipe, so that it is difficult to sufficiently and effectively apply the magnetic treatment to the entire water.

  Further, in order to sufficiently and effectively perform magnetic treatment on the liquid (water), it is preferable to dispose the permanent magnet so as to be in close proximity and in direct contact with the liquid (water). However, in the configuration in which the permanent magnets are arranged opposite to the outside of the water supply pipe, the distance from the permanent magnet increases toward the central portion of the water supply pipe, and accordingly, the magnitude (strength) of the magnetic force is accordingly increased in the center of the water supply pipe. Smaller (weaker) toward the part. In this case, since a uniform magnetic force cannot be applied uniformly to the entire liquid (water), there is a difference in the degree of magnetic treatment. In other words, a part that can sufficiently perform magnetic treatment on the liquid (water) flowing in the water supply pipe and a part that cannot be sufficiently magnetically generated are generated, and as a result, the magnetic treatment on the entire liquid (water) is sufficiently and effectively performed. It becomes difficult to apply.

  Here, the permanent magnets as described above can be classified into sintered magnets (Patent Document 2), bonded magnets (Patent Document 3) and the like depending on the state and manufacturing method. In this case, the sintered magnet is formed by using a magnetic material (magnetic powder) exhibiting hard magnetism such as ferrite or rare earth element as a basic material, and adding a sintering aid as necessary to this, and forming the molded body. It is manufactured by magnetizing after heat-sintering and aging treatment (precipitation hardening treatment).

  By the way, in the sintering process of the sintered magnet, in the sintering process for the molded body, the magnetic material may contract during the cooling process, which may cause a large distortion in the molded body. For this reason, for example, in precision instrument applications where dimensional accuracy of 0.1 to 0.01 mm or less is required, the surface of the sintered magnet (molded body) is subjected to mechanical processing such as cutting, grinding, and polishing, thereby causing distortion. The desired dimensional accuracy is ensured by eliminating the above. However, such machining is time-consuming and time-consuming, which increases the magnet manufacturing cost.

  In recent years, along with the diversification of various equipment, it has been required to reduce the thickness and diameter of sintered magnets incorporated in the equipment, but depending on the degree of thickness reduction and diameter increase, During processing, the molded body may be cracked, cracked or chipped. In this case, the yield as a sintered magnet is deteriorated, not only the production efficiency is lowered, but many of them are discarded as defective products, and the cost for the disposal is generated separately. .

  On the other hand, a bonded magnet, for example, mixes magnetic powder with various non-magnetic resins, and after molding this into various shapes by various molding processes such as injection molding and compression molding (press molding), the molded body It is manufactured by performing a magnetizing process on. Such a bonded magnet is excellent in its moldability and has a high degree of processing freedom as compared with the sintered magnet described above. In the manufacturing process of bonded magnets, no sintering process is required, and no large distortion occurs in the binder (mixed resin), so the surface of the compact must be machined, such as cutting, grinding, and polishing. It is possible to ensure a desired dimensional accuracy.

  By the way, since the non-magnetic resin is mixed in the bonded magnet, the magnetic characteristics may be deteriorated as compared with the sintered magnet. For example, when a bonded magnet is manufactured by mixing magnetic powder and resin at a weight ratio of 8: 2, the volume ratio of magnetic powder and resin in the bonded magnet is often about 5: 5. In this case, if the volume ratio of the magnetic powder to the resin is increased, the proportion of the magnetic powder (magnetic powder density) in the total volume of the bonded magnet increases, so that the magnetic characteristics can be improved.

  However, when the volume ratio of the magnetic powder to the resin is increased, for example, the fluidity at the time of injection molding is lowered, and it may be difficult to spread the resin smoothly to every corner of the molding die. In this case, there is a limit to increasing the volume ratio of the magnetic powder to the resin in order to keep the fluidity at the time of injection molding constant. For this reason, there was a certain limit in improving the magnetic characteristics of the bonded magnet.

In such a bonded magnet, for example, the magnetic field orientation of each magnetic powder is aligned in a certain direction to form a molded body, and the molded body is magnetized to become an anisotropic magnet, improving its magnetic properties. Can be made. However, such an orientation process must be performed in a state where a magnetic field is applied when the bonded magnet is formed. In this case, since the application control of the magnetic field is also performed simultaneously with the control of the molding operation, the control becomes complicated and takes time and effort, and as a result, the manufacturing cost of the bonded magnet increases.

  The present invention has been made in order to solve such problems, and its purpose is to uniformly apply magnetic treatment to the entire liquid so as to remove rust, prevent corrosion, and remove and prevent adhesion of various scales. An object of the present invention is to provide a magnetic processing apparatus having excellent magnetic characteristics.

  In order to achieve such an object, the present invention is a magnetic processing apparatus that can be arranged in the flow paths of various liquids and performs a magnetic process on the liquids, and includes a plurality of magnetic processing apparatuses incorporating permanent magnets. Magnetic generation units, a magnetic covering member arranged so as to surround these magnetic generation units, and at least one magnetic shaft interposed between the magnetic generation unit and the magnetic covering member. ing. In this case, the permanent magnet is integrally formed by joining together a magnet structure made of a sintered material of a predetermined shape obtained by molding and sintering a plurality of magnetic materials with a joining material, and the permanent magnet is incorporated. The magnetic interaction between the magnetic generation unit, the magnetic covering member, and the magnetic shaft generates a uniform magnetic force over the entire region surrounded by the magnetic covering member, and flows along the region. Magnetic treatment is applied to the entire liquid.

  According to the present invention, a permanent magnet is integrally formed by joining together a magnet structure composed of a sintered material of a predetermined shape obtained by molding and sintering a plurality of magnetic materials, and incorporating the permanent magnet. Since at least one magnetic material shaft is interposed between the magnetism generating unit and the magnetic material covering member, a magnetic processing device having excellent magnetic characteristics is realized. In this case, since a uniform magnetic force can be applied to the entire liquid, the entire liquid can be magnetically treated. Thereby, rust removal and corrosion prevention in the flow path, and removal and adhesion prevention of various scales can be achieved.

  In the magnetism generating unit, at least a pair of adjacent permanent magnets are opposed to each other with the same polarity, and a magnetic yoke plate is interposed between the pair of permanent magnets with the same polarity facing each other. The magnetic flux density can be improved. In addition to this, the magnetic flux density can be further improved by covering the permanent magnet with the magnetic cover. Thereby, the magnetic processing capability with respect to the liquid can be dramatically increased.

  Furthermore, by providing the magnetic force increasing mechanism in the region surrounded by the magnetic body covering member, it is possible to increase the magnetic force action on the liquid flowing along the region. Specifically, the magnetic field width (strength) can be remarkably improved by applying a helical structure made of a magnetic material as a mechanism for increasing the magnetic force action and generating magnetic field lines in a spiral shape. In addition to this effect, by increasing the residence time of the liquid flowing along the spiral structure, the number of times the liquid flowing along the region surrounded by the magnetic body covering member contacts the magnetic lines of force is increased. be able to.

  In addition, since the plurality of openings formed in the magnetic body covering member can cause turbulent flow in the liquid flowing along the region surrounded by the magnetic body covering member, the flowing liquid comes into contact with the lines of magnetic force. The number of times can be further increased. Thereby, the magnetic treatment can be performed efficiently and reliably on the entire liquid.

  Hereinafter, a magnetic processing apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings. Applications of magnetic processing equipment include, for example, various flow paths (piping) such as water supply systems, hot water supply systems, various cooling water systems, and air conditioning cold / hot water systems built in residences and apartment buildings, medical facilities and commercial facilities, hot springs and lodging facilities, etc. The liquid can be disposed inside, and the liquid that flows in the pipe (for example, water, cooling water, hot spring water, etc.) can be uniformly and efficiently subjected to magnetic treatment.

  As shown in FIGS. 1 (a) and 1 (b), the magnetic processing apparatus of the present embodiment includes a plurality of magnetism generating units 2 in which permanent magnets (see FIGS. 2 and 5) are incorporated, and these magnetism generation units. A magnetic body covering member 4 disposed so as to surround the unit 2 and at least one magnetic body shaft 6 interposed between the magnetism generating unit 2 and the magnetic body covering member 4 are provided to generate magnetism. The magnetic interaction between the unit 2, the magnetic body covering member 4 and the magnetic body shaft 6 generates a uniform magnetic force over the entire area surrounded by the magnetic body covering member 4, and flows along the area. The entire liquid is magnetically processed.

  In the present embodiment, as an example, six magnetism generating units 2 are arranged in a region surrounded by a hollow cylindrical magnetic covering member 4, and circles provided on both sides of the magnetic covering member 4. Each magnetic generation unit 2 is positioned and supported in a region surrounded by the magnetic body covering member 4 by the plate-like support plate 8. In addition, as a material of the support plate 8, for example, 300 series (301, 304, 316, etc.) stainless steel (SUS) can be applied, and stainless steel 304 is particularly preferable.

  More specifically, a support shaft 10 extending along the magnetic body covering member 4 is inserted into each magnetism generating unit 2, and screw portions (for example, for example, A male screw 10s is formed (see FIG. 2). In this case, after the six magnetism generating units 2 are set in the region surrounded by the magnetic body covering member 4, the screw portions 10 s on both ends of each magnetism generating unit 2 are fixed to both support plates 8. In a state of projecting to the outside from a hole (not shown), a nut 12 (nut with an internal thread cut into the inner diameter) is screwed into the threaded portion 10s from the outside of each support plate 8 and tightened, thereby supporting shaft 10. Can be supported between the support plates 8.

  Further, the nuts 12 are further screwed along and tightened along the respective screw portions 10s, so that the respective support plates 8 can be pressed and fixed to both sides of the magnetic body covering member 4, and thereby the support plates 8 can be mutually fixed. The six magnetism generating units 2 supported therebetween can be positioned and supported in the region surrounded by the magnetic body covering member 4. As other support methods, both end sides of the support shaft 10 may be welded or welded to the support plate 8 or bonded with an adhesive.

  In the configuration example of FIG. 1, a disk-shaped support plate 8 is fixed at the same center with respect to the hollow cylindrical magnetic body covering member 4, and one of the six magnetism generating units 2 is a magnetic body. It is positioned and supported at the center of the support plate 8 so as to be concentric with the covering member 4, and the remaining five around the magnetic generating unit 2 are positioned and supported concentrically and at equal intervals along the circumferential direction. Has been. In this case, the distance between the centers of the six magnetism generating units 2 (the distance between the support shafts 10) is set to be equal to each other. In addition, as a material of the support shaft 10, for example, stainless steel (SUS) of No. 400 series (403, 405, 410, 430, 434, etc.) can be applied, and stainless steel 430 is particularly preferable.

  As shown in FIG. 2A, a plurality of permanent magnets 14 are incorporated in the magnetism generating unit 2, and at least a pair of adjacent permanent magnets 14 are arranged so that the same poles face each other. . A yoke plate 16 made of a magnetic material is interposed between a pair of permanent magnets 14 with the same polarity facing each other, and each permanent magnet 14 is a magnetic material cover 18 made of a magnetic material. It is covered. More specifically, the basic unit 2a is configured by arranging two disk-shaped permanent magnets 14 together and concentrically sandwiching the disk-shaped yoke plates 16 therebetween. Then, the two permanent magnets arranged on both sides of the yoke plate 16 are covered with a hollow cylindrical magnetic cover 18.

  In this case, the material of the yoke plate 16 and the magnetic cover 18 may be, for example, 400 series (403, 405, 410, 430, 434, etc.) stainless steel (SUS), and stainless steel 430 is particularly preferable. . Further, the magnetic body cover 18 covered on both sides of the yoke plate 16 is waterproof, and when the magnetic body cover 18 is attached to the yoke plate 16 (for example, welding, welding, or adhering with an adhesive), the inside is covered. Since the airtight and liquid tight states are achieved, the permanent magnets 14 on both sides of the yoke plate 16 are not directly exposed to the liquid.

  In the configuration example of FIG. 2A, a yoke plate 16 is interposed between permanent magnets 14 in which N poles are opposed to each other, thereby generating an N-pole magnetic field line from the yoke plate 16. 2a is configured. The N-wave basic unit 2 a is formed with a through hole 2 h that penetrates from the permanent magnet 14 to the yoke plate 16 and the magnetic body cover 18 at the center thereof. In this case, the support shaft 10 is inserted into the through hole 2h, and a plurality of N-wave basic units 2a are arranged along the support shaft 10. A single magnetism generating unit 2 in which a plurality of N-wave basic units 2 a are fixed to the support shaft 10 can be configured by tightening with the fixing nut 20 from both sides (screw portion 10 s) of the support shaft 10. In this case, the magnetic flux density can be set to an arbitrary strength (Gauss) according to the number of N-wave basic units 2 a arranged on the support shaft 10.

  For example, if the strength of one permanent magnet 14 is 800 gauss, the magnetic flux density of the N-wave basic unit 2a in which the permanent magnet 14 is incorporated is about 4,200 gauss, and two permanent magnets on both sides of the yoke plate 16 are further provided. Is covered with the magnetic cover 18, the magnetic flux density rises to about 5,000 Gauss. And by arranging a plurality of such N-wave basic units 2a along the support shaft 10, the magnetic flux density can be set to about 7,000 gauss or more. The number of N-wave basic units 2a arranged is not particularly limited here because it is arbitrarily set according to the purpose of use and the usage environment.

  Here, as an example of the permanent magnet 14 applicable to the magnetism generating unit 2, it is preferable to apply a neodymium magnet. A neodymium magnet is the most powerful magnet on the market, and its magnetic force is 10 times or more that of a normal ferrite magnet and 6 to 7 times that of an alnico magnet. As a result, the magnetism generating unit 2 using the neodymium magnet can generate a strong magnetic force of about 7000 gauss. However, neodymium magnets are vulnerable to heat, and the magnetic force may decrease when a certain temperature is exceeded. Considering such a case, a heat-resistant neodymium magnet may be applied. Other permanent magnets 14 may be boron, cobalt, iron, or the like in addition to ferrite magnets (Ba ferrite, Sr ferrite), alnico magnets, and samarium magnets.

In the present embodiment, for example, as shown in FIG. 5 (h), the permanent magnet 14 includes a magnet structure 14a made of a sintered material having a predetermined shape formed by sintering a plurality of magnetic materials (not shown). It is integrally formed by joining together with the joining material 14b. In this case, a hard magnetic material (magnetic powder) containing at least one of neodymium, boron, samarium, cobalt, iron, and ferrite as described above is applied as the magnetic material, and the magnetic material (magnetic powder). The magnet structure 14a is configured as a sintered material having a predetermined shape by molding and sintering. And, as the bonding material 14b, a material (for example, resin, adhesive, etc.) having bonding characteristics under a predetermined setting condition is applied, and by joining the plurality of magnet components 14a to each other by the bonding material 14b, a predetermined value is obtained. A permanent magnet 14 having a contour shape is integrally formed.
In addition, the manufacturing method of this permanent magnet 14 is later mentioned in FIG. 5, for example.

  In such a magnetic generation unit 2, an annular spacer 22 is interposed between the N-wave basic units 2 a, and a predetermined amount is set between the N-wave basic units 2 a according to the width dimension of the spacer 22. A gap W is formed. When the gap W is configured in this way, a part of the liquid flowing along the region surrounded by the magnetic body covering member 4 enters the gap W, and rotates around the magnetism generating unit 2, for example, spirally. While flowing. In this case, the number of times that the liquid comes into contact with the N-pole magnetic lines of force generated from the yoke plate 16 increases, so that the magnetic processing efficiency for the liquid is improved. Further, the rotational flow of the liquid can be changed according to the size of the gap W between the N-wave basic units 2a, but the gap W can be arbitrarily set according to the purpose of use and the usage environment of the magnetism generating unit 2. Since it is set, the numerical value is not particularly limited here.

  Here, the configuration of the magnetism generating unit 2 is not limited to that shown in FIG. 2 (a). Instead, for example, as shown in FIG. 2 (b), the permanent magnet 14 having S poles opposed to each other is used. A yoke plate 16 may be interposed therebetween. In this case, the magnetism generating unit 2 composed of the S wave basic unit 2 b for generating S polar magnetic lines of force from the yoke plate 16 is configured. Further, for example, as shown in FIG. 2C, the magnetism generating unit 2 may be configured by combining an N-wave basic unit 2a and an S-wave basic unit 2b. In any configuration (FIGS. 2B and 2C), the effect is the same as that of the magnetic generation unit 2 shown in FIG.

  The magnetic body covering member 4 is formed with a plurality of openings 4h (see FIG. 1). These openings 4h cause turbulence in the liquid flowing along the region surrounded by the magnetic body covering member 4. Can be made. More specifically, the liquid that has flowed to the magnetic body covering member 4 through the plurality of liquid flow ports 8h (see FIG. 1) formed in the support plate 8 circulates through a part of the plurality of openings 4h. The whole is stirred, and as a result, the liquid becomes a turbulent flow and flows along the region surrounded by the magnetic body covering member 4. At the same time, the liquid flowing along the region surrounded by the magnetic body covering member 4 partially flows into the gap W, and flows while rotating around the magnetism generating unit 2, for example, spirally. Thereby, the frequency | count that a liquid contacts with the magnetic field line of the N pole magnetism which has arisen from the yoke board 16 increases, and the magnetic processing efficiency with respect to a liquid can be improved greatly.

  Note that the size of each opening 4h and the number per unit area are arbitrarily set according to the purpose and environment of use of the magnetism generating unit 2, and are not specifically limited here. The size, number, and position of the liquid flow port 8h can be arbitrarily set as long as the liquid can smoothly flow along the region surrounded by the magnetic body covering member 4. However, in order to insert a magnetic shaft 6 described later, it is preferable to form the liquid flow port 8h while avoiding at least portions that support both ends of the magnetic shaft 6.

  As shown in FIG. 1, in the magnetic processing apparatus of the present embodiment, a magnetic material shaft 6 is interposed between a plurality (six in the drawing) of the magnetism generating units 2 and the magnetic material covering member 4. Has been. Here, considering the positional relationship between the five magnetic generation units 2 and the magnetic material covering member 4 that are positioned and supported concentrically around the single magnetic generation unit 2 and at equal intervals along the circumferential direction, Between these five magnetism generating units 2 and the magnetic body covering member 4, five relatively wide spaces are formed at equal intervals along the circumferential direction. In this case, the five spaces have a central portion at a position relatively away from the magnetism generating unit 2 and the magnetic body covering member 4, so that the magnetic flux density of the central portion is lower than that of the other portions.

  Therefore, when one magnetic shaft 6 is inserted in the central portion of each of these five spaces, the magnetic shaft 6 is magnetized by receiving the magnetic force action of the magnetism generating unit 2, and the magnetic shaft 6 is surrounded. As a result, the magnetic flux density in these five spaces can be improved to the same magnitude (strength) as the other parts. Thereby, a uniform magnetic force can be generated over the entire region surrounded by the magnetic body covering member 4 by the magnetic interaction between the magnetic generation unit 2 and the magnetic body covering member 4 and the magnetic body shaft 6. Thus, the entire liquid flowing along the region can be magnetically applied.

  In addition, as an insertion method of the magnetic body shaft 6, for example, when screw portions (for example, male screws) 6 s are formed on both end sides of the magnetic body shaft 6, first, screw portions on both end sides of the magnetic body shaft 6. 6s is protruded outside from fixing holes (not shown) formed in both support plates 8. In this state, a nut 24 (a nut having an internal diameter cut into an inner diameter) is screwed into the threaded portion 6s from the outside of each support plate 8 and tightened. Thereby, the magnetic body shaft 6 can be fixed between the support plates 8 in a state where the magnetic body shaft 6 is interposed between the magnetic generation unit 2 and the magnetic body covering member 4. As other methods, both end sides of the magnetic material shaft 6 may be welded or welded to the support plate 8 or bonded with an adhesive. The material of the magnetic shaft 6 may be, for example, 400 series (403, 405, 410, 430, 434, etc.) stainless steel (SUS), and stainless steel 430 is particularly preferable.

Here, a process will be described in which the magnetic processing apparatus of the present embodiment is disposed in, for example, a flow path (pipe) of a water supply system, and magnetic treatment is performed on a liquid (water) flowing through the flow path (pipe).
The liquid (water) flowing through the flow path (pipe) of the water supply system flows into the magnetic body covering member 4 from the plurality of liquid flow ports 8h of the support plate 8 in the magnetic processing apparatus. At this time, the liquid (water) that has flowed to the magnetic body covering member 4 is partly circulated through the plurality of openings 4h so that the entire liquid (water) is agitated. As a result, the liquid (water) is turbulent. And flows along the region surrounded by the magnetic body covering member 4. At the same time, a part of the liquid (water) flowing along the region surrounded by the magnetic body covering member 4 enters the gap W of the magnetism generating unit 2, for example, spirals around the magnetism generating unit 2. Flow while rotating.

  That is, the liquid (water) that has flowed into the magnetic body covering member 4 flows while extending the residence time along the region surrounded by the magnetic body covering member 4 by repeating turbulent flow and spiral rotation. At this time, the liquid (water) flows in the region surrounded by the magnetic body covering member 4 while increasing the number of times of contact with the magnetic field lines generated from the magnetism generating unit 2, and during that time, the liquid (water) Magnetic treatment is performed efficiently and reliably. A magnetic shaft 6 is interposed between the magnetism generating unit 2 and the magnetic body covering member 4, and a uniform magnetic force is generated over the entire region surrounded by the magnetic body covering member 4. Therefore, the entire liquid (water) flowing through the region is uniformly subjected to magnetic treatment.

  Here, magnetic treatment is a treatment method that uses a phenomenon (electromagnetic induction phenomenon) in which current flows through a conductor (water) when the conductor (water) moves in a magnetic field. The condition is that the liquid (water) passes at right angles to the magnetic field (magnetic field). This is because the magnetic processing is established when the magnetic field, current, and water flow (force) act at right angles to each other according to Fleming's left-hand rule. According to such a magnetic treatment process, the crystal structure of various components (for example, iron ions, calcium ions, chloride ions, sulfate ions, carbon dioxide, etc.) contained in the liquid (water) that may cause rust or scale changes. However, it becomes a stable equilibrium form in which the crystal does not become large.

  Specifically, the main component of the scale is the precipitation of calcium ions in water, but in a magnetically treated liquid (water), the crystal structure of calcium is small (in a stable equilibrium form), and the crystal It is easy to disperse (dissolve) by suppressing the growth of. Thereby, it becomes difficult to adhere as a scale to the flow path (pipe) of the water supply system, and it flows out without staying in the flow path (pipe). In addition, the scale that has already adhered to the flow path (pipe) has a round crystal structure (particles), the adhesion between them decreases, and gradually peels and flows out. Furthermore, since the magnetically treated liquid (water) has an action of restoring the original properties of water existing in nature, for example, generation of slime and algae is prevented.

There are _two types of rust: iron trioxide (Fe ₂ O ₃ ) called “red rust” and iron tetroxide (Fe ₃ O ₄ ) called “black rust”, but red rust is unstable. It always grows and causes red water, while black rust is a strong passivity. In this case, when the liquid (water) is magnetically processed, the red rust is converted into magnetite (iron tetroxide), and the magnetite becomes a passive protective film, thereby preventing the growth of red rust and the generation of red water. That is, when a magnetite film is formed on the surface of red rust, oxygen and corrosion factors in the liquid (water) are blocked, so that the growth of red rust and the generation of red water are prevented. At the same time, since the magnetized red rust is easily peeled off, the red rust adhering to the flow path (pipe) is gradually peeled and flowed out by repeating peeling and magnetizing.

  As described above, according to the magnetic processing apparatus of the present embodiment, the magnetic shaft 6 is interposed between the magnetic generation unit 2 and the magnetic body covering member 4 so that a uniform magnetic force acts on the entire liquid. Therefore, the entire liquid can be magnetically treated. Thereby, rust removal and corrosion prevention in the flow path, and removal and adhesion prevention of various scales can be achieved.

  In the magnetism generating unit 2, at least a pair of adjacent permanent magnets 14 are opposed to each other with the same polarity, and a yoke plate 16 made of a magnetic material is interposed between the pair of permanent magnets 14 with the same polarity facing each other. By doing so, the magnetic flux density can be improved. In addition to this, the magnetic flux density can be further improved by covering the permanent magnet 14 with the magnetic body cover 18. Thereby, the magnetic processing capability with respect to the liquid can be dramatically increased.

  Furthermore, the plurality of openings 4h formed in the magnetic body covering member 4 can cause turbulent flow in the liquid flowing along the region surrounded by the magnetic body covering member 4, so that the flowing liquid has a line of magnetic force. The number of contact with can be further increased. Thereby, the magnetic treatment can be performed efficiently and reliably on the entire liquid.

In addition, this invention is not limited to embodiment mentioned above, It can change as follows.
For example, in the magnetic processing apparatus shown in FIGS. 3A to 3D, the action of magnetic force on the liquid flowing along the region is increased in the region surrounded by the magnetic body covering member 4 (see FIG. 1). There may be provided a mechanism for increasing magnetic force action. In this case, the magnetic force action increasing mechanism can be provided, for example, in one or both of the magnetism generating unit 2 and the magnetic material shaft 6 and extends spirally along the region surrounded by the magnetic material covering member 4. Magnetic helical structures 26, 28, 30, 32 are provided.

  FIG. 3A shows a configuration example of the spiral structure 26 provided in the magnetism generating unit 2. The spiral structure 26 is configured separately from the magnetism generating unit 2 and is spirally wound around the outer periphery of the magnetism generating unit 2 at a predetermined turning pitch P. In this case, the spiral structure 26 has a substantially circular cross section with a predetermined diameter, and both ends thereof are fixed to the magnetism generating unit 2. As the material of the spiral structure 26, for example, 400 series (403, 405, 410, 430, 434, etc.) stainless steel (SUS) can be applied, and stainless steel 430 is particularly preferable.

  According to such a configuration, the magnetic field lines can be generated spirally by the spiral structure 26, whereby the width (strength) of the magnetic field can be remarkably improved, and the liquid flowing along the spiral structure 26 can be obtained. Therefore, it is possible to increase the number of times that the liquid flowing along the region surrounded by the magnetic body covering member 4 contacts the magnetic field lines. Thereby, rust removal and corrosion prevention in the flow path, and removal / adhesion prevention of various scales can be achieved more efficiently and reliably. In addition, since the turning pitch P and the diameter dimension of the spiral structure 26 are arbitrarily set according to the use purpose and use environment of a magnetic processing apparatus, they are not specifically limited here.

  FIG. 3B illustrates the magnetism generating unit 2 in which a plurality of permanent magnets 14 and the entire yoke plate 16 are covered with a single magnetic cover 18. In this example, the spiral structure 28 is configured integrally with the magnetism generating unit 2 and is wound spirally along the outer peripheral surface of the magnetic cover 18 at a predetermined turning pitch P. In this case, the effect is the same as that of the above-described spiral structure 26 (see FIG. 3A) except that the spiral structure 28 has a thin plate shape with a substantially rectangular cross section having a predetermined width dimension. Therefore, the description thereof is omitted.

Further, as the material of the spiral structure 28, for example, 400 series (403, 405, 410, 430, 434, etc.) stainless steel (SUS) can be applied, and stainless steel 430 is particularly preferable. In addition, since the turning pitch P and width dimension of the spiral structure 28 are arbitrarily set according to the use purpose and use environment of a magnetic processing apparatus, they are not specifically limited here.

  FIG. 3C shows a configuration example of the spiral structure 30 provided on the magnetic shaft 6. The spiral structure 30 is configured separately from the magnetic shaft 6, and is spirally wound at a predetermined turning pitch P along the outer periphery of the magnetic shaft 6. In this case, the spiral structure 30 has a substantially circular cross section with a predetermined diameter, and both ends thereof are fixed to the magnetic shaft 6. In addition, as a material of the helical structure 30, for example, stainless steel (SUS) of No. 400 series (403, 405, 410, 430, 434, etc.) can be applied, and stainless steel 430 is particularly preferable.

  According to such a configuration, the magnetic field lines can be generated spirally by the spiral structure 30 so that the width (strength) of the magnetic field can be significantly improved, and the liquid flowing along the spiral structure 30 Therefore, it is possible to increase the number of times that the liquid flowing along the region surrounded by the magnetic body covering member 4 contacts the magnetic field lines. Thereby, rust removal and corrosion prevention in the flow path, and removal / adhesion prevention of various scales can be achieved more efficiently and reliably. In addition, since the turning pitch P and diameter dimension of the spiral structure 30 are arbitrarily set according to the use purpose and use environment of a magnetic processing apparatus, they are not specifically limited here.

  FIG. 3D illustrates a helical structure 32 configured integrally with the magnetic material shaft 6. The spiral structure 32 is configured integrally with the magnetic shaft 6, and is spirally wound at a predetermined turning pitch P along the outer peripheral surface of the magnetic shaft 6. In this case, the effect is the same as that of the above-described spiral structure 30 (see FIG. 3C), except that the spiral structure 32 has a thin plate shape with a substantially rectangular cross section having a predetermined width dimension. Therefore, the description thereof is omitted.

  Here, as a method of integrating the helical structure 32 with the magnetic shaft 6, for example, the helical structure 32 may be retrofitted (welded, welded, bonded) to the outer peripheral surface of the magnetic shaft 6, or The spiral structure 32 may be integrally formed simultaneously with the formation of the magnetic shaft 6. Further, as the material of the spiral structure 32, for example, stainless steel (SUS) of No. 400 series (403, 405, 410, 430, 434, etc.) can be applied, and stainless steel 430 is particularly preferable. In addition, since the turning pitch P and width dimension of the spiral structure 32 are arbitrarily set according to the use purpose and use environment of a magnetic processing apparatus, they are not specifically limited here.

  Further, in the magnetic generation unit 2 of the above-described embodiment, the spacer 22 (see FIGS. 1 and 2) is not necessarily a necessary component, and the yoke plate 16 is interposed by interposing the yoke plate 16 instead of the spacer 22. You may comprise so that the permanent magnet 14 of the same polarity may adjoin on both sides of. For example, FIG. 4A shows a configuration example in which the yoke plate 16 is interposed instead of the spacer 22 in the magnetism generating unit 2 of FIG. 2A. Also, for example, FIG. 4B shows a configuration example in which the yoke plate 16 is interposed instead of the spacer 22 in the magnetism generating unit 2 of FIG. In these configuration examples, the yoke plate 16 is interposed for each of the two permanent magnets 14. However, the present invention is not limited to this. For example, as shown in FIGS. 4 (c) and 4 (d), A yoke plate 16 may be interposed for each permanent magnet 14.

In the magnetic processing apparatus of the above-described embodiment, a silver-containing material that releases silver ions may be included in the liquid to remove chlorine in the liquid. In this case, as the silver-containing material, for example, various silver compounds may be used in addition to silver. However, since the amount of released silver ions increases or decreases in proportion to the silver content, a material having a high silver content is selected. It is preferable to do.
As a method for incorporating the silver-containing material, for example, it may be applied to the surface of the magnetic generation unit 2, the magnetic body covering member 4, or the magnetic body shaft 6, or may be embedded.

Here, a manufacturing method of the permanent magnet 14 applied to the above-described embodiment will be described with reference to FIGS.
First, in accordance with the thickness and size (for example, diameter) of the permanent magnet 14 to be manufactured, a predetermined number for forming the contour of the permanent magnet 14 together with a required number of magnet components 14a (FIG. 5A). A container 34 having a contour shape is prepared (FIG. 5B). Then, after the predetermined number of magnet constituents 14a are accommodated in the accommodating body 34 (FIG. 5C: magnet constituent accommodating step), the accommodating member 34b is filled in the accommodating body 34, and the magnet constituents 14a are mutually connected. Joining (FIG. 5 (d), FIG. 5 (e): joining material filling step).

  Subsequently, the pressing body 36 is pressed against the container 34 to integrally mold the molded body 14m along the contour shape of the container 34 (FIG. 5 (f), molded body forming step). Thereafter, the molded body 14m is taken out from the container 34 and subjected to predetermined surface treatment (for example, removal of burrs and dust, surface finishing, etc.), whereby the molded body 14m is made permanent as shown in FIG. It can be manufactured as a magnet 14. As the container 34, for example, various types, containers, bags, and the like can be arbitrarily selected and applied. However, in the present embodiment, a case where a mold is applied is assumed as an example.

  As described above, the magnetic material of the magnet structure 14a can be made of a hard magnetic material containing at least one of neodymium, boron, samarium, cobalt, iron, and ferrite. For example, a hard magnetic and ferromagnetic magnet powder such as an Nd—Fe—B rare earth magnet or an Sm—Co rare earth magnet may be arbitrarily selected and applied as a material for the magnetic material of the magnet structure 14a. In this Embodiment, the magnet structure 14a is comprised with the sintered material which comprises the predetermined shape which shape | molded and sintered such magnet powder. In this case, various conditions such as the temperature and time during sintering are not particularly limited here because they are set to predetermined conditions depending on, for example, the type and material of the magnetic material (magnet powder). Further, when the magnetic material (magnet powder) is sintered, a predetermined sintering aid may be added. In addition, the sintered material after sintering is subjected to an aging treatment (precipitation hardening treatment), and the sintered material subjected to the aging treatment is processed into a predetermined shape (for example, cutting or grinding). The magnet structure 14a is configured.

  The magnet structure 14a can be set to any shape and size that can be accommodated in the container (die) 34, and is not particularly limited. For example, all the magnet structures 14a have the same shape. And may be set to different shapes and sizes. Moreover, as each magnet structure 14a, shapes, such as a cube, a rectangular parallelepiped, a polygon, a sphere, and a disk, may be applied, or shapes, such as plate shape, rod shape, line shape, and a ring, are applied. Also good. Further, for example, in the sintering and processing in the manufacturing process of the sintered magnet, it is possible to directly apply the waste material or the end material of defective products due to the occurrence of cracks, cracks, chips, etc. as the magnet structure 14a. For this reason, it becomes possible to reuse and effectively utilize the rare earth element sintered magnetic material which is a rare and expensive resource, and it is possible to greatly reduce the amount of waste materials and scraps to be disposed of as waste. In addition, the cost for disposing of these waste materials and scraps can be greatly reduced.

  In addition, the number of magnet constituents 14a to be accommodated in the accommodating body (mold) 34 in the magnet constituent accommodating step (FIG. 5C) is not particularly limited. 5 (g) shows a perspective view of a state in which a plurality of magnet constituent bodies 14a are housed in a housing body (die) 34. In this case, each magnet constituent body 14a is The magnet components 14a may be accommodated in a state where a predetermined gap is secured between them, or may be accommodated in a state where they are laid out without a gap. And may be accommodated so as to overlap each other in a state of being laid down or in an upright state.

  In addition, you may perform the magnetic field orientation process for aligning the magnetic field of each magnetic material of a sintered material to predetermined one direction to the magnet structure 14a. When such a magnetic field orientation process is performed in advance, the magnet structure 14a has anisotropy, so that the magnetic characteristics when magnetized can be improved, and the magnet structure 14a can be magnetized. In addition to being able to create a stronger magnetic field, the magnet has a high coercive force (hard to demagnetize) and can generate a stable strong magnetic force. In this case, when performing the magnet component housing step (FIG. 5C) using the magnet component 14a that has been subjected to the magnetic field orientation process in advance, each magnet component 14a has its magnetic field direction set to a certain direction (for example, Therefore, it is necessary to accommodate in the container (die) 34 in the vertical direction of FIG.

In the present embodiment, the bonding material 14b is made of a material having bonding characteristics under predetermined setting conditions. Examples of the material include various resins (rubber, synthetic resin (plastic)) and various adhesives. Can be applied. In this case, as the synthetic resin, for example, a thermoplastic resin that softens when heated to a predetermined temperature such as polyethylene, polypropylene, and polyamide, and a thermosetting resin that cures when heated to a predetermined temperature such as epoxy, phenol, and polyester are arbitrarily applied. can do. Further, as the adhesive, for example, a reactive adhesive (such as an epoxy adhesive) that is solidified by mixing two liquids can be arbitrarily applied. In addition, what is necessary is just to selectively apply a thermoplastic resin and a thermosetting resin with the shaping | molding method in a molded object formation process.
Moreover, as the form of the bonding material 14b, materials having various forms such as a solid body, a fluid body, a granular body, and a powder body can be applied at a predetermined temperature or a predetermined pressure. For example, the above-mentioned various resin compounds or pellets may be applied as the bonding material 14b.

  Further, in the bonding material filling step (FIGS. 5D and 5E), the bonding material 14b as described above is heated in the cylinder 38, for example, to have fluidity, and the container (gold It is preferable to perform high-pressure injection (for example, injection) into the mold 34. As a result, the bonding material 14b can be distributed to the corners of the container (mold) 34 without any gaps (evenly), and the magnet components 14a can be bonded to each other without any gaps. In this case, the filling amount (injection amount) of the bonding material 14b is, for example, the size of the container (die) 34 or the amount (number, volume, etc.) of the magnet component 2 housed in the container (die) 34. Since it is arbitrarily set by the above, there is no particular limitation here. Further, the filling condition (for example, pressure and speed at the time of injection) of the bonding material 14b is arbitrarily set depending on, for example, the material (for example, viscosity) of the bonding material 14b, and is not particularly limited here.

  According to such a bonding material filling step, in order to ensure the fluidity of the bonding material 14b when filling the container (die) 34 (during injection), the amount of the bonding material 14b with respect to the magnet constituting body 14a is reduced. There is no need to increase it at all. For this reason, the weight ratio of the magnet structure 14a to the bonding material 14b is not reduced, and the volume ratio of the magnet structure 14a to the bonding material 14b can be easily and dramatically increased. As a result, even if the volume ratio of the bonding material 14b to the magnet structure 14a is 10 to 20%, it is possible to manufacture the permanent magnet 14 having excellent moldability that can sufficiently secure the bonding strength. In addition, it is possible to manufacture a permanent magnet 14 having a magnetic property that is about 80% of that of a sintered magnet and 50% or more higher than that of a bonded magnet.

  In addition, after the bonding material 14b is filled in the container (die) 34, in the molded body formation step (FIG. 5 (f)), each magnet component 14a and the bonding material 14b are connected to the container (die) 34. A formed body 14m formed integrally along the contour shape is formed. In this case, the molding method of the molded body 14m is not particularly limited, and for example, any method such as injection molding or compression molding (press molding) can be applied. Here, when injection molding is applied as the molding method, the bonding material 14b filled by high-pressure injection into the container (mold) 34 in the bonding material filling step described above is cooled to a predetermined temperature together with the magnet structure 14a. Thus, the molded body 14m can be integrally molded along the contour shape of the container (mold) 34. In this case, as the bonding material 14b, for example, a thermoplastic resin such as polyethylene, polypropylene, and polyamide may be used.

  On the other hand, when compression molding (press molding) is applied as the molding method, pressure and heat are applied to the container (mold) 34 in the molded body forming step, and the container (mold) ) The high pressure injection into the bonding material 14b filled with the magnet 14a is compressed and bonded (fixed) together, so that the molded body 14m is integrally molded along the contour shape of the container (mold) 34. can do. In this case, as the bonding material 14b, for example, a thermosetting resin such as epoxy, phenol, or polyester may be used. In the molded body forming step, a mold clamping process is performed, and after the bonding material 14b injected into the housing body (mold) 34 is shaped together with the magnet structure 14a, the molding is performed by pressurization, heating and compression. The body 14m may be integrally formed along the contour shape of the container (die) 34.

In any molding method, the molded body 14m has a configuration in which a plurality of magnet constituent bodies 14a are joined together by a joining material 14b to form one permanent magnet 14. In this case, conditions such as the magnitude of pressure and temperature at the time of molding are arbitrarily set depending on, for example, the size of the molded body 14m and the material of the bonding material 14b.
According to such a molding method, simply changing the shape of the container (mold) 34, for example, a molded body having a complicated shape such as a disk having many through holes penetrating from the upper surface to the lower surface. Even with a length of 14 m, it can be easily and integrally molded. As a result, it is possible to provide a permanent magnet 14 having an arbitrary shape according to the use environment or purpose of use of the magnetic processing apparatus. In addition, according to such a molding method, there is no occurrence of cracks, cracks, chips, etc., which occurred in the conventional magnet manufacturing process.

  In the present embodiment, a mold is applied as the container 34. However, for example, a container or a bag may be applied as the container 34. In this case, for example, the container or the like is made of the above-described thermoplastic resin or the like, and the magnet composition 14a is accommodated in the container or the like in the magnet composition accommodation process, and then the joining material 14b is injected in the bonding material filling process. Then fill. In the molded body forming step, the container and the like are sealed and heated and pressurized together with the magnet structure 14a and the bonding material 14b, and the container and the like are integrally bonded (fixed) to them. According to this, the molded body 14m is molded such that the outer shape of the container or the like forms the outer shape of the molded body 14m as it is.

  Moreover, in this Embodiment, you may make it perform a magnetization process with respect to the said molded object 14m after a molded object formation process (molded object magnetization process). In the molded body magnetizing step, the molded body 14m can be configured as a magnetized permanent magnet 14 by performing a magnetization process. In this case, the magnetizing process for the molded body 14m is, for example, a magnetization form such as double-sided magnetization, single-sided double-pole magnetization, single-sided multipole magnetization, double-sided double-pole magnetization, depending on the application or purpose of the permanent magnet 14. May be arbitrarily selected and applied by a predetermined magnetizing method so that a predetermined portion of the molded body 14m forms a predetermined magnetic pole. Further, when the molded body 14m is formed in a ring shape, for example, the molded body 14m is magnetized by outer peripheral two-pole magnetization, outer peripheral multi-pole magnetization, inner peripheral two-pole magnetization, and inner peripheral multi-pole magnetization, What is necessary is just to comprise the permanent magnet 14. FIG. In addition, the magnetization method with respect to the molded object 14m is not specifically limited, For example, arbitrary methods, such as a static magnetic field magnetization and pulse magnetization, are applicable. Moreover, you may surface-treat with respect to the molded object 14m as needed before a molded object magnetization process.

Here, the magnetic properties of the magnetized permanent magnet according to the present embodiment (hereinafter referred to as the present magnet) were tested and verified. The test contents and test results will be described below.
In this test, two permanent magnets of the present magnet and a predetermined sintered magnet (hereinafter referred to as a comparative magnet) were prepared as samples, and the magnetic fluxes of the respective magnets were measured and compared.

In this case, as the present magnet, a magnet formed by integrally forming a magnet structure, a bonding material, and a container was used.
The magnet structure of the present magnet uses an Nd—Fe—B sintered magnet (maximum energy product: 44 (MGOe)) as a sintered material, and the sintered magnet is a rectangular parallelepiped (vertical: 4. 0 (mm), width: 4.0 (mm), thickness: about 1.4 (mm)). Further, the magnet housing includes an annular (ring-shaped) housing (outer diameter: 26.9 (mm), inner diameter: 12.1 (mm), thickness: 4 (mm), cross-sectional area: 4 .53 (mm ² )) resin case (weight: 2.1 (g)) was used. In addition, the said resin case was comprised so that the whole shape might comprise the cyclic | annular form concentric with an accommodating part.
Further, as a pretreatment for the test, a plurality of the above-described magnet structures were accommodated in a resin case, and the bonding material was filled and fixed in the resin case, and then magnetized. Note that a resin agent was used as the bonding material, and 0.48 (g) of the resin agent was filled.

  On the other hand, the comparative magnet uses an Nd—Fe—B sintered magnet (maximum energy product: 44 (MGOe)) similar to the magnet structure of the present magnet, and the sintered magnet is annular (ring Shape) (outer diameter: 26.9 (mm), inner diameter: 12.1 (mm), thickness: 0.98 (mm), cross-sectional area: 4.53 (mm2)). Constructed with layers. Thereby, the volume of the comparative magnet was set to be approximately the same size as the volume of the housing portion of the resin case of the present magnet. In addition, in order to make the configuration of the entire comparative magnet the same as the present magnet, as a pretreatment for the test, the comparative magnet is accommodated in the same resin case as the present magnet, and the resin agent similar to the present magnet is further added to the resin. The case was filled and fixed by 0.38 (g) (hereinafter, the pre-treated comparative magnet is referred to as a comparative magnet body).

  In the test, first, the total weight of the magnet and the comparative magnet body were measured, and the weight of the resin case and the weight of the resin agent were subtracted from the total weight. The weight (the total magnet weight W1) and the weight of the comparative magnet (comparative magnet weight W2) were calculated. As a result, the total weight of the magnet is 14.4 (g), and the total magnet weight W1 is calculated to be 11.82 (g) (W1 = 14.4.2.1-0.48). It was. On the other hand, the total weight of the comparative magnet body is 15.8 (g), and the comparative magnet weight W2 is calculated to be 13.32 (g) (W2 = 15.8-2.1-0.38). It was done. In this case, the weight ratio (aggregation density with respect to volume) X of the present magnet total weight W1 to the comparative magnet weight W2 was 0.887 (X = W1 / W2 = 11.82 / 13.32).

Next, the magnetic flux amount (MaxWell) of the magnet and the comparative magnet is measured, and the ratio of the magnetic flux amount of the magnetic magnet (magnetic flux Φ1 of the magnetic magnet) to the magnetic flux amount of the comparative magnet (comparing magnet magnetic flux Φ2) (magnetic flux ratio Y). ) Was calculated. As a result, the present magnet magnetic flux Φ1 was 6260 (MaxWell), while the comparative magnet magnetic flux Φ2 was 7020 (MaxWell). Thereby, the magnetic flux ratio Y of the present magnet magnetic flux Φ1 to the comparative magnet magnetic flux Φ2 was calculated as 0.891 (Y = Φ1 / Φ2 = 6260/7020).
When the magnetic flux density of the magnet (the magnet magnetic flux density B1) is calculated as the amount of magnetic flux (the magnet magnetic flux Φ1) with respect to the cross-sectional area of the housing portion of the resin case, the magnet magnetic flux density B1 is 1.382 (G). (B1 = 6260 / 4.53). On the other hand, when the magnetic flux density of the comparative magnet (comparative magnet magnetic flux density B2) is calculated as the magnetic flux amount (comparative magnet magnetic flux Φ2) with respect to the cross-sectional area of the comparative magnet, the comparative magnet magnetic flux density B2 is 1.550 (G). (B2 = 7020 / 4.53).

As a result, it was verified that the magnetic flux ratio (0.891) with respect to the comparative magnet was substantially equal to the weight ratio (0.887) with respect to the comparative magnet. Further, when the volume of the housing portion of the resin case and the volume of the comparative magnet are substantially the same, it was verified that the present magnet had a magnetic flux ratio of 0.89 (89%) with respect to the comparative magnet. That is, this magnet has 89% magnetic characteristics (magnetic flux) of the comparative magnet (Nd—Fe—B based sintered magnet) when the volume ratio (volume ratio) of the housing part of the resin case and the comparative magnet is substantially equal. It was verified that it had.
In addition, as described above, manufacturing a ring-shaped (ring-shaped) sintered magnet such as a comparative magnet is very time-consuming and costly. In addition, an annular (ring-shaped) permanent magnet having substantially the same magnetic properties as a sintered magnet can be manufactured at low cost.

  By manufacturing the permanent magnet 14 by the above permanent magnet manufacturing method, the permanent magnet 14 having excellent magnetic properties can be easily and reliably manufactured, and the permanent magnet 14 having excellent moldability can be easily manufactured. And it can manufacture reliably. Thereby, the yield at the time of manufacture of the permanent magnet 14 excellent in the magnetic characteristic and the moldability can be remarkably improved. Further, it is possible to sufficiently and accurately meet the needs for the shape and size of the permanent magnet 14 having excellent magnetic properties.

  Furthermore, as described above, a sintered magnetic material having an arbitrary shape and size can be applied to the magnet structure 14a. For example, waste materials and end materials of various sintered magnetic materials (molded bodies 14m) are used. Even if it is, it can apply as the magnet structure 14a. For this reason, the permanent magnet 14 excellent in magnetic properties and formability can be manufactured while reusing and effectively utilizing the rare earth element sintered magnetic material which is a rare and expensive resource. As a result, it is possible to greatly reduce the amount of waste materials and scraps to be disposed of as waste, and it is possible to greatly reduce the cost for disposing of these waste materials and scrap materials. Further, since the expensive sintered rare earth element magnetic material can be reused and effectively used, the permanent magnet 14 having excellent magnetic properties and formability can be manufactured at low cost.

  In addition, since the permanent magnet 14 manufactured by the permanent magnet manufacturing method according to the above-described embodiment is not necessarily arranged with an even magnet structure 14a (see FIG. 5 (h)), the residual magnetic flux The density is not strictly uniform, and the magnetic field generated by the permanent magnet 14 may be uneven. However, if a magnetic field of a predetermined magnitude or more is generated from the entire permanent magnet 14, particularly the magnetic pole surface (for example, the upper surface and the lower surface in FIG. 5 (h)), the permanent magnet 14 may be, for example, a general household. It is clear from experience that it can withstand practical use for a wide variety of applications such as various electrical appliances for industrial use and various industrial equipment and devices.

  For example, when a permanent magnet is used for removing chlorine or scale from tap water, it is sufficient that a magnetic force having a predetermined magnitude acts on the tap water, and the residual magnetic flux density of the permanent magnet becomes strictly equal. There is no problem at all. As described above, according to the permanent magnet and the manufacturing method thereof according to the above-described embodiment, the permanent magnet 14 capable of easily generating a strong magnetic field can be manufactured at low cost. It is possible to meet the needs of a wide range of fields that require permanent magnets at low cost.

  Further, since such a permanent magnet 14 is entirely covered with the bonding material 14b and is not directly exposed to the outside, the permanent magnet 14 is subjected to a magnetic treatment as shown in FIG. When incorporated in the magnetism generating unit 2 of the apparatus, it is not always necessary to cover each permanent magnet 14 with the magnetic body cover 18. As a result, the number of parts of the magnetic processing apparatus can be reduced, and as a result, the apparatus can be made compact and the manufacturing cost can be reduced.
