TECHNICAL FIELD OF THE INVENTION
The present invention relates to a magnetic water treatment apparatus for preventing internal corrosion of piping such as a water supply pipe, a hot water supply pipe, a cooling water pipe, and an air conditioning pipe.
[0002]
[Prior art]
Conventionally, various means have been considered as means for preventing internal corrosion of pipes through which water flows, such as water supply pipes, hot water supply pipes, cooling water pipes, air conditioning pipes, that is, rust, but without using chemicals. A magnetic water treatment method is known as an environmentally superior method.
[0003]
In this magnetic water treatment system, water is turned into magnetized water by traversing a magnetic field, and magnetite is generated on the inner surface of the pipe by the action of the magnetized water, thereby stopping the progress of corrosion. Water is magnetized efficiently by crossing the magnetic field lines at right angles.
[0004]
In a conventional magnetic water treatment apparatus, a magnet is attached to the outer surface of a pipe or a rod-shaped magnet is bundled, and magnetic treatment is performed simply by passing water through a magnetic field. In the magnetic water treatment method, as described above, it is effective that water crosses the magnetic field lines at right angles, and even if the water is blindly passed through the magnetic field, the electronic excitation does not always occur effectively.
[0005]
Therefore, various improvements have been made in the past to allow water to flow across the poles of the magnet at right angles and to form a magnetic field having a higher magnetic flux density between the magnetic poles. For example, there is a structure in which a wound spiral structure is provided on the outer periphery of a laminated body of magnets, and water flows in a horizontal direction and flows at right angles between poles.
[0006]
Further, as a device in which a magnetic field having a higher magnetic flux density is formed between magnetic poles, there is a device in which a notch is provided in a magnetic pole piece. This is because, when a magnetic metal piece is sandwiched between magnets of the same polarity, magnetic force gathers at the cut edge of the metal piece.By providing a notch in the metal piece, the magnetic flux density of each magnet is reduced. The magnetic force of 2.5 to 3.0 times comes out of the cut.
[0007]
Notches in the metal pieces are also used to allow water to flow laterally and cross the gaps at right angles. This is to shift the cutout positions of the metal pieces provided in the magnet laminated body in order, so that water flows in a spiral shape, and as a result, the same effect as in the case where a spiral is formed can be obtained.
[0008]
[Problems to be solved by the invention]
However, as described above, providing a spiral wound structure on the outer periphery of the magnet laminate or providing notches in the magnetic pole piece complicates the structure and takes time and effort to manufacture, and as a result, As a result, the manufacturing cost increases.
Under such circumstances, it has been desired to improve the efficiency of the magnetic water treatment apparatus by achieving simplification of the structure and securing a passage through which water flows at right angles between the poles of the magnet. In order to meet such a demand, for example, as disclosed in Japanese Patent Application Laid-Open No. H10-165958, a plurality of magnets are laminated with a magnetic metal plate interposed therebetween and facing the same pole. A magnetic water treatment apparatus formed by combining a plurality of laminates has been considered.
[0009]
In the above-mentioned magnetic water treatment apparatus, its performance is determined by the strength (magnetic flux density) of the magnetic poles of the magnet. Therefore, a magnet having a strength corresponding to the performance required of the water treatment apparatus is required, and it is necessary to manufacture or prepare the magnet according to the performance of the apparatus. On the other hand, there is a problem that the magnet may lack corners, and it is not preferable that the magnets flow into the treated water.
[0010]
[Means for Solving the Problems]
The present invention solves the above-mentioned problem, and its configuration is a magnetic water formed by combining a plurality of laminated bodies formed by laminating a plurality of magnets sandwiching a metal plate having magnetism and facing the same pole. In the processing apparatus, the magnet is formed of a combination of a plurality of magnet pieces.
According to the magnetic water treatment apparatus having the above-described configuration, different performance requirements can be met by preparing magnet pieces having a predetermined magnetic flux density and combining them by changing the number of magnet pieces.
[0011]
Further, a configuration according to the present invention is characterized in that the magnet pieces are housed in a case so as to overlap each other. In the magnetic water treatment apparatus according to the present invention, since the magnet pieces are housed in the case, the magnet pieces are hardly chipped and do not flow into water even if they are cut off.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, a magnetic water treatment apparatus according to the present invention will be described based on one embodiment shown in the drawings. FIG. 1 shows a perspective external view of a magnetic water treatment apparatus according to one embodiment of the present invention, FIG. 2 shows an exploded perspective view of a part thereof, FIG. 3 shows a plane viewed from a water flow control plate, 4 shows a partially crushed side surface, FIG. 5 shows a cross section of a magnet, and FIG. 6 shows a state where the combined laminated body is assembled in a cylindrical casing. The embodiment shown in FIGS. 1 to 6 is a four-axis magnetic water treatment apparatus formed by combining four laminates.
[0013]
A laminated body is formed by arranging a columnar magnet 2 such that the same poles face each other with a metal plate 1 having a substantially quarter circle (fan shape) having magnetism therebetween. An N-pole laminated body 3a formed by sandwiching the plate 2 between the N poles in the first stage and sequentially laminating the magnets 2 with the plate 1 sandwiched between the S poles and between the N poles in the first stage, In the first stage, an S-pole laminated body 3b is formed by sandwiching the plate 1 between the S-poles and sequentially laminating the magnets 2 between the N-poles and between the S-poles and the plate 1 therebetween. The plate 1 and the magnet 2 are provided with rectangular holes 4 and 5, and the plate 1 and the magnet 2 are separated by passing a support bolt shaft 6 having a rectangular cross section through these holes 4 and 5. It is laminated.
[0014]
As shown in FIG. 5, the magnet 2 is formed by stacking a plurality of magnet pieces 2a of the same shape (disk shape) in a cylindrical metal case 21 with a bottom. A square hole 5 is formed in the center of the magnet piece 2a. A square hole 22 is also formed in the center of the bottom 21 a of the case 21. The support bolt shaft 6 is passed through these holes 5 and 22. FIG. 5 shows a magnet having an N pole on the front surface side. To make the surface an S pole, the magnet pieces 2a may be turned upside down and stacked. To obtain magnets 2 having different magnetic forces, that is, different magnetic flux densities, the number of magnet pieces 2a to be overlapped may be changed. The case 21 does not need to have a bottom on the entire surface as shown in this example, and may have a flange-like bottom.
[0015]
The N-pole stacked body 3a and the S-pole stacked body 3b are arranged two by two concentrically and alternately in the circumferential direction and combined. That is, the four fan-shaped plate members 1 are arranged so as to form a substantially circular shape. With such an arrangement, adjacent magnets 2 in the same plane have different magnetic poles, and adjacent plate members 1 magnetized by the magnets 2 also have different magnetic poles.
[0016]
End face fixing plates 7 are arranged at both ends of the combined N-pole laminate 3a and S-pole laminate 3b. The end face fixing plate 7 includes a ring-shaped edge portion 7a and a cross-shaped stay portion 7b. At four positions of the stay portion 7b, a square hole 8 for passing the support bolt shaft 6 is formed. A square hole 10 for passing a center fixing bolt shaft 9 is formed in the center of the portion 7b.
[0017]
The N-pole laminated body 3a and the S-pole laminated body 3b are tightened with nuts 11 on the threaded portions 6a at both ends of the support bolt shaft 6 passed from one end face fixing plate 7 to the other end face fixing plate 7 and the center fixing bolt. The nut 9 is fastened to the threaded portions 9a at both ends of the shaft 9 so that the shaft 9 is restrained and assembled to form an assembly 12. In the assembled state, gaps 13 are formed between the adjacent plate members 1 at regular intervals, which serve as water passages.
[0018]
A water flow control plate 14 is provided at an appropriate position in the axial direction of the assembly 12 (the laminating direction of the plate 1 and the magnet 2). As shown in FIG. 3, the water flow control plate 14 is provided with a water passage hole 15 so as to allow the flow of water only between adjacent magnets 2 having different magnetic poles. The portion corresponding to the magnetic pole of the adjacent magnets 2 between the same magnets is closed, so that water does not flow. The shape of the water passage hole 15 is not limited to a circle, but various shapes such as an ellipse and a rectangle can be considered. The water flow control plate 14 is also provided with rectangular holes 8 and 10 for passing the support bolt shaft 6 and the center fixing bolt shaft 9 similarly to the end face fixing plate 7. The water flow control plate 14 also serves to increase the rigidity of the assembly 12, prevent twisting, and improve the workability of assembly.
[0019]
The assembly 12 is housed in a cylindrical casing 16. The casing 16 comprises two tube portions 16a and 16b. After the assembly 12 is housed, the flange portions 17a and 17b of the tube portions 16a and 16b are connected. Both ends of the casing 16 are connection portions 18a, 18b to the pipe. That is, by being assembled to the pipe, one side of the assembly 12 is on the water inflow side and the other side is on the water discharge side.
[0020]
In this embodiment, a disk-shaped magnet piece 2a constituting the magnet 2 has been described, but the shape of the magnet piece 2a is not limited to this, and a rectangular parallelepiped or other shapes are possible. The metal plate material 1 which is a component of the laminates 3a and 3b is not limited to a substantially 1/4 circular shape, but may have various shapes such as a triangle and a quadrangle. The number of stages of the laminates 3a and 3b is increased in accordance with the required capacity, thereby increasing the passage area, that is, the number of gaps 13 that become water passages.
[0021]
Next, the magnetizing action of water by the magnetic water treatment device will be described.
A magnetic force acts between adjacent plate materials 1 having different magnetic poles in the same plane to generate a magnetic field W. The water flowing from the end of the pipe portion 16a of the casing 16 passes between the plate members 1 and crosses the magnetic field lines of the magnetic field W at substantially right angles. As the water crosses the lines of magnetic force, the water is magnetized and becomes magnetized water.
[0022]
The water flowing into the assembly 12 is guided between the different plate members 1 by the water passage holes 15 of the water flow control plate 14, so that the water flows so as to cross the magnetic field lines of the magnetic field W at right angles. When water, which is an electric conductor, crosses the magnetic field lines at right angles, an exciting action occurs, energy is converted, and the water is magnetized. Therefore, the water is efficiently magnetized by traversing the lines of magnetic force of the repetitive magnetic field substantially at right angles. The magnetized water is discharged from the other end of the casing 16 and reaches the inside of a pipe connected thereto.
[0023]
Since the magnet 2 accommodates the magnet piece 2a in the case 21, the magnet piece 2a is hardly chipped, and even if it is chipped, the fragment remains in the case 21 and does not flow into the treated water.
[0024]
If the amount of water to be treated increases, it is necessary to increase the gap 13 between the plate materials 1 which is a passage for passing water. If the gap 13 is made large, the magnetic force acting on the gap 13 decreases if the same magnet is used, that is, the magnetic flux density decreases. To compensate for this, the volume of the magnet must be increased, and a magnet is required for each capability of the apparatus. However, if the volume is increased by stacking the magnet pieces 2a as in the magnet 2 according to the present invention, it is not necessary to manufacture or prepare a magnet according to the required capacity of the device. . Since the magnetic flux density generated at the edge of the plate 1 has a correlation with the magnetic flux density of the magnet 2 and the area of the plate 1, etc., by knowing these in advance, the magnetization of water according to the required processing capacity can be achieved. You can gain the ability.
[0025]
The magnetic water treatment apparatus according to the present invention prevents corrosion by magnetized water in a pipe as follows.
As shown in FIG. 7A, when water flows in the steel pipe 19, the iron in the pipe 19 turns into divalent iron ions and dissolves in the water. Divalent iron ions combine with hydroxyl ions in water to become ferrous hydroxide (Fe (OH) ₂ ).
[0026]
As shown in FIG. 7B, ferrous hydroxide is immediately oxidized by oxygen or the like in water to become ferric hydroxide (Fe (OH) ₃ ). This ferric hydroxide is a corrosion product called so-called red rust, and corrodes the inner surface of the pipe 19 and becomes squirrels and rises on the inner surface of the pipe 19. And when this dissolves in the water, it becomes red water.
[0027]
As shown in FIG. 7C, when the magnetized water generated by the magnetic water treatment apparatus flows into the pipe 19, that is, when the electromotive force is sufficiently induced on the flowing water side, ferrous hydroxide is used. Has an antioxidant property and is unlikely to become ferric hydroxide, and as a result, magnetite (Fe ₃ O ₄ ) in which divalent iron ions and trivalent iron ions are combined starts to be generated from inside red rust. Magnetite is a strong anti-corrosion protective film that is resistant to corrosion and is not attacked by oxygen or chlorine, and stops the progress of corrosion and stops the generation of red rust and eventually red water.
[0028]
As shown in FIG. 7D, when the magnetite crystals gradually increase and cover the inner surface of the pipe 19, the corrosion stops. With the generation of magnetite, the soft portion of red rust on the surface peels off and flows out.
[0029]
As shown in FIG. 7 (e), the dense and stable magnetite film completely stops the progress of corrosion. Therefore, red rust and red water resulting therefrom are not generated thereafter.
[0030]
Further, the magnetized water prevents the scale from adhering to the inner surface of the pipe and removes the scale adhering to the inner surface of the pipe. In other words, calcium ions and magnesium ions contained in the water and causing the scale are enhanced in the degree of hydration by the magnetized water and are less likely to adhere to the inner wall of the pipe. In addition, the magnetic field affects the dynamic characteristics of crystallization, the crystal structure becomes a round polyhedron, the tight bonding at the tube wall is hindered, and the tube is easily peeled off by the water flow.
[0031]
In order to control the flow of water flowing into the assembly 12 from the first stage, the water entry side of the end face fixing plate 7 that restricts the laminates 3a and 3b may be replaced with the water flow control plate 14. .
[0032]
In addition, the present invention is not limited to the water treatment apparatus according to the above-described configuration, and alternately changes the size of the plate members 1 in the laminates 3a and 3b in the stacking direction to change the distance between the plate members 1 adjacent in the water flow direction. Also, the present invention can be applied to a magnetic water treatment apparatus of a type in which a magnetic field is generated.
