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 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.

  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. It is to provide a magnetic processing apparatus.

  In order to achieve such an object, the present invention is a magnetic processing apparatus that can be disposed in the flow paths of various liquids and performs magnetic processing on the liquids, and has a permanent magnet incorporated therein. A plurality of magnetic generation units, a magnetic body covering member disposed so as to surround these magnetic generation units, and at least one magnetic body shaft interposed between the magnetic generation unit and the magnetic body covering member I have. In this case, the magnetic interaction between the magnetic generation unit, the magnetic body covering member, and the magnetic body shaft generates a uniform magnetic force over the entire area surrounded by the magnetic body covering member, along the area. Magnetic treatment is applied to the entire flowing liquid.

  According to the magnetic processing apparatus of the present invention, a uniform magnetic force can be applied to the entire liquid by inserting at least one magnetic material shaft between the magnetic generation unit and the magnetic material covering member. 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, 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 3) 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. In addition, as the permanent magnet 14 other than this, for example, a ferrite magnet (Ba ferrite, Sr ferrite), an alnico magnet, or a samarium-based magnet may be applied.

  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.

  Here, as a method of integrating the spiral structure 28 with the magnetic body cover 18, for example, the spiral structure 28 may be retrofitted (welded, welded, bonded) to the outer peripheral surface of the magnetic body cover 18, or The spiral structure 28 may be integrally formed simultaneously with the formation of the magnetic body cover 18. 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.
