Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water quality improving device for improving the water quality by subjecting a liquid such as water flowing in a pipe to a magnetizing treatment.

[0002]

2. Description of the Related Art FIG. 13 is a sectional view showing a conventional water quality improving device 1. Such a conventional technique is disclosed, for example, in Japanese Examined Patent Publication No. 1-56322 (JP-A-61-211619). The water quality improving device 1 is configured by arranging a permanent magnet 4 on the outer periphery of a cylindrical pipe line 2 made of a non-magnetic material through which liquid passes and surrounding the pipe line 2 in a ring shape. The permanent magnets 4 are arranged in a plurality of rows in the tube axis 5 direction, and the magnetic poles of the permanent magnets 4 lined up in the tube axis 5 direction face each other with the tube path 2 in between.
Of the magnetic pole, which is formed of a magnetic material and surrounds the duct 2 is arranged between the adjacent permanent magnets 4. Therefore, each permanent magnet 4
From the N pole side ball piece 3 to the S pole side ball piece 3
A magnetic field is formed in the conduit 2 over. With such a structure, an alternating magnetic field in which the N pole and the S pole are periodically switched along the tube axis 5 is generated inside the pipe line 2, and the magnetic field acts on the water to be treated flowing in the pipe line 2.

By applying a magnetic field to the water to be treated flowing in the conduit 2 in this way, the water quality can be improved.

[0004]

In such a conventional water quality improving device 1, since the permanent magnets 4 are arranged with the same poles facing each other with the pipe 2 interposed therebetween, the ball piece 3 on the N pole side. The magnetic lines of force generated from the peripheral wall provided with are curved in the conduit 2 and enter the ball piece 3 on the S pole side of the peripheral wall on the same side. Therefore, the strength of the magnetic field is strongest in the vicinity of the peripheral wall portion of the conduit 2 and weakest in the vicinity of the central portion, as shown in FIG.

Therefore, in order to increase the treatment capacity of the water quality improvement device 1 having such a configuration, when the inner diameter of the conduit 2 is increased to increase the flow rate of the water to be treated, the conduit 2
The magnetic field acting near the center of the pipe becomes weak, and the magnetic field hardly acts on the water passing near the center of the pipeline. There is a problem that it cannot be increased.

Therefore, an object of the present invention is to prevent the magnetic field at the center of the pipe through which the water to be treated passes from becoming weak,
An object of the present invention is to provide a water quality improving device capable of reliably magnetically treating the water to be treated in the pipeline.

[0007]

According to the present invention, a pair of magnetic poles, which are different from each other on both sides with respect to one plane including the pipe axis, are arranged in a pipe passage through which water to be treated passes and which is made of a non-magnetic material. Alternatively, the magnetic water quality improving device is characterized by including a plurality of pairs of permanent magnets and holding means for holding the permanent magnets on both sides with respect to the one plane. According to the present invention,
The permanent magnets held by the holding means are arranged in pairs so that different magnetic poles are opposed to each other on both sides with respect to one plane including the tube axis, so that the permanent magnets exit from the one permanent magnet whose N pole side is directed to the tube path. The magnetic field lines pass through the central portion of the conduit and enter the other permanent magnet whose S pole side faces the conduit, and a magnetic field is formed in the conduit. Therefore, even if the inner diameter of the pipeline through which the water to be treated passes is increased, the magnetic field is reliably formed in the pipeline from one permanent magnet to the other permanent magnet without weakening the magnetic field at the center of the pipeline. Therefore, it is possible to surely perform the magnetization process. Therefore, even if the inner diameter of the conduit is increased, it is possible to prevent a region where the magnetic field hardly acts from occurring in the central portion of the conduit and increase the processing capacity.

Further, the holding means of the present invention is characterized in that at least one of the direction in which the permanent magnet is moved toward and away from the pipe line, and the longitudinal direction substantially perpendicular to the direction in which the permanent magnet is moved toward and away from the pipe line and along the pipe axis direction. It is characterized in that it is held displaceably. According to the present invention, the permanent magnet is held by the holding means so as to be displaceable in at least one of the approaching / separating direction and the longitudinal direction. Therefore, by arranging the permanent magnets on both sides with respect to one plane including the tube axis. The permanent magnets are displaced by a magnetic attraction force so as to face each other on a straight line perpendicular to the tube axis so as to sandwich the tube path. Therefore, by roughly arranging each of the permanent magnets with the conduit interposed therebetween, each of the permanent magnets is accurately positioned by the magnetic attraction force. Further, even when a plurality of permanent magnets arranged in the longitudinal direction are held by the holding means so as to be displaceable, by disposing a pair of magnet rows across the duct, the opposing permanent magnets form pairs. It is positioned exactly on both sides of the pipe line, that is, on both sides with respect to one plane including the pipe axis, and aligned on a straight line perpendicular to the pipe axis. Further, the permanent magnets of the magnet array are positioned at equal intervals in the longitudinal direction by the magnetic repulsive force of the permanent magnets adjacent in the longitudinal direction. As a result, the permanent magnets are positioned so that the magnetic field acting on the water to be treated passing through the pipe is substantially uniform, and the magnetic field can be effectively exerted on the water to be treated. Further, since each permanent magnet pair is positioned at an optimum position for sandwiching the pipeline on a straight line perpendicular to the pipe axis, for example, even if the pipeline is curved, each permanent magnet pair is curved in the pipe of the curved pipeline. It is arranged on a straight line perpendicular to the axis and is positioned so that the magnetic field acts most effectively on the water to be treated passing through the conduit.

The permanent magnets arranged in pairs according to the present invention are characterized in that surfaces facing each other are substantially parallel to each other. According to the present invention, since the surfaces of the permanent magnets facing each other are substantially parallel to each other, the distances between the permanent magnets forming a pair are all substantially equal to each other, whereby the permanent magnets forming a pair sandwiching the conduit are provided. The magnetic field formed is uniform, and the magnetic field can be effectively applied to the water to be treated that passes through the pipeline. Further, even if the outer diameter of the conduit to be mounted changes, the permanent magnets are provided with the parallel surfaces sandwiching the conduit, so that the size of the conduit can be changed by changing the interval between the conduits. This is acceptable and saves the trouble of forming a new permanent magnet depending on the pipeline.

The permanent magnet 19 held by the holding means 13 may be a substantially rectangular parallelepiped lump, or may be a plurality of plate-shaped permanent magnets magnetically attracted.

The conduit 11 is formed in a substantially rectangular tube shape, and the sectional shape of the conduit 11 is, for example, 100 mm in length × 50 m in width.
Permanent magnet 1 is formed in a rectangle of m

1 to be treated water.

The facing surfaces 19a of the permanent magnets 19 arranged in pairs of the respective permanent magnets 19 are formed on the tube shaft 2
It is provided so as to cover at least the width of the side surface having one long side. Further, since the surfaces 19a facing each other are parallel to each other, the magnetic fields formed by the permanent magnets 19 facing each other are uniformly formed, and the magnetic fields uniformly act on all the water to be treated passing through the conduit 11. be able to.

The holding means 13 is constructed by combining a plurality of angle steels and is fixed to the pipe line 11, and the magnet 19 and the pipe shaft 21.
The magnetic poles different from each other are held on a straight line 22 perpendicular to the pair so as to be arranged in pairs so as to face each other. For example, three pairs of such permanent magnets 19 are provided, each of which is provided with a conduit 11
Holding means 1 in the pipe line 11 at equal intervals in the direction of the pipe axis 21
Fixed by 3.

The housing 12 is formed in the shape of a hollow box having a substantially rectangular parallelepiped shape, and accommodates the conduit 11 and the permanent magnet 19 fixed to the conduit 11. From the upper wall 23 and the lower wall 34 of the housing 12, respectively, the upper end 11a and the lower end 1 of the conduit 11 are connected.
1b is provided so as to project, and the conduit 11 and the housing 12 are liquid-tightly fixed. Further, the pipe line 11 is sandwiched by the pair of mounting members 20 made of angle steel and fixed to the lower wall 24 in the housing 12, and is securely fixed to the housing 12.

At the upper end 11a and the lower end 11b of the pipe line 11, a discharge port 16 for discharging the water to be treated and an intake port 15 for the water to be treated are respectively provided on one side (left side in FIG. 1). Respectively connected to. Each of the intake port 15 and the exhaust port 16 is formed in a short cylindrical shape, and is connected with, for example, a rubber hose. Lower end 11b of pipeline 11
A drain pipe 17 having a drain cock 18 is provided in the pipe 1. By opening the drain cock 18, the pipe line 1
It is possible to discharge the precipitate settled in 1 through the drain pipe 17 to the outside. The upper end 11a of the conduit 11 is liquid-tightly sealed by an upper lid 25 and a plurality of bolts 26.

A base 14 formed by combining angle steel is fixed to the lower wall 24 of the housing 12, and the water quality improving device 10 is vertically mounted with the base 14 facing down.
The occupied area can be reduced.

Since each of the conduit 11, the housing 12, the holding means 13 and the base 14 is made of a non-magnetic austenitic stainless steel such as SUS305 defined in JIS, the magnetic field of the permanent magnet 19 is disturbed. That is, the magnetic field generated by the permanent magnet 19 can be effectively applied to the water to be treated in the conduit 11.

The height L1 of the housing 12 is, for example, 80.
The length L2 is selected to be 400 mm, the width L3 is selected to be 450 mm, and the height L4 of the base 14 is selected to be 345 mm, for example.

The magnetic force of the permanent magnets 19 is selected to be about 1200 to 1800 Gauss at the center of the pipe line 11, that is, at the pipe axis 21, which is equidistant from each surface 19a of each permanent magnet 19. By providing three such magnet pairs, a processing capacity of about 750 to 2000 liters / minute is obtained. The strength of the magnetic field alternately acts on the water to be treated which passes through the inside of the conduit 11 depending on the portion where the permanent magnet 19 is provided and the portion where the permanent magnet 19 is not provided, whereby the treated water is effectively magnetized.

Further, the number of magnet pairs is not limited to three, and one, two or more than three pairs may be used, and in the case of one pair, the processing capacity is about 50 to 150 liters / minute, and in the case of two pairs. Is about 250 to 750 liters / minute. By thus increasing the number of magnet pairs, the water quality improving device 10 can be easily installed.
The processing capacity of can be increased. Further, since the magnet pairs are arranged so that different magnetic poles are opposed to each other, the magnetic field acts on all the water to be treated passing through the pipeline 11 without weakening the magnetic field at the central portion of the pipeline 11 to remove the water in the pipeline. Magnetic processing can be reliably performed.

Next, the magnetically treated water that has been treated with such a magnetic field will be described. Water such as tap water and groundwater contains several kinds of ions, for example, Ca ²⁺ (calcium ion), Na ⁺ (sodium ion), H ⁺ (hydrogen ion), SO ₄ ^2- (sulfate ion), CO ₃ ^{2 -} (carbonate ions), Cl ^- (chlorine ions), OH ^- (hydroxide ion)
Etc. are dissolved. These ions are extremely rare when dissolved alone, and usually exist as large clusters surrounded by water molecules that are bound to each other by hydrogen bonds. When the water to be treated containing such clusters crosses the magnetic field at a flow velocity higher than a certain level, the MHD (ma
gnetohydrodynamics) clusters containing positive or negative ions in the water to be treated are subjected to physical force (force of Ampere), resulting in the phenomenon that hydrogen bonds are broken. As a result, the clusters are miniaturized and the water to be treated is ionized.

Water molecules are also activated by the MHD reaction when they cross the magnetic field, and are brought into a high energy state. Normally, the bond angle ∠HOH formed by the oxygen and hydrogen atoms of the water molecule is about 1
Although it is 04.5 °, the bond angle in the high energy state is about 16
5 °. Water that has been magnetically treated like this
Lasts for more than 4 hours.

The magnetically treated water having such a small cluster and high energy has a high dissolving power and can dissolve rust adhering to a pipe or the like to prevent rust from adhering and red water. .

When a suspended substance having a positive or negative polarity crosses a magnetic field at a flow velocity higher than a certain level, the suspended substance attempts to line up with the magnetic field, but is obstructed by the viscosity of water and passes through the magnetic field. When this happens, the energy is sharply increased by the MHD reaction, resulting in a high potential state. When such high potential particles come into contact with the low potential scale material adhering to the pipe, a discharge phenomenon occurs and destroys the crystallinity of the scale. As a result, the hard scale gradually changes to a soft substance, and the surface is gradually peeled off by a stream of water and swept away to remove it. In this way, for example, scale, rust, sludge, etc. adhering to a pipe such as a boiler can be removed.

According to the groundwater quality test, if the groundwater in which 21,000 general bacteria are detected is magnetically processed by the water quality improving device 10, the water quality is reduced to 1600 in 1 ml, and then the two water quality improving devices 10 are used. It was confirmed by the magnetic treatment of the groundwater in the previous term that the number decreased to 8 in 1 ml. Further, in this experiment, in the case of one water quality improvement device 10, the iron content was 0.13
from 0.07 mg / liter to 0.05 mg / liter in the case of two water quality improvement devices 10.
It was confirmed that the volume was reduced to less than 1 liter.

According to an experiment for investigating the effect of the magnetically treated water on Escherichia coli, the Escherichia coli is scattered one by one in the water not subjected to the magnetic treatment, but the E. coli in the magnetically treated water are aggregated and clumped together to form a large one. It was observed that a bacterial mass was formed. This is explained by the fact that bacteria are normally negatively charged, but by magnetic treatment, they combine with positively charged substances in a solution to form a large mass.
Bacteria thus formed into aggregates can be easily removed by a filter such as gauze. The magnetic force at the center of the pipe 11 of the water quality improving device 10 used in this experiment is 1480 gauss, the flow velocity is 0.5 m / sec, and the water pressure is 0.2 kg / cm ² .

Therefore, by providing it in the water such as the water receiving tank, the elevated water tank, the piping system, the water supply pipe and the drainage pipe of the building / condominium, it is possible to suppress the generation of miscellaneous algae, slime and rust, and to facilitate cleaning. .

It has also been confirmed by experiments with a hardness indicator that the hard water is softened by the magnetic treatment. When used as washing water, soft water is preferable, so that magnetically treated water can also improve washing efficiency. In addition, the relationship between softening water and temperature is about 10 minutes for softening water but 2 minutes or less for warming water,
Warm water is easier to soften. The difference in the thermal conductivity of the magnetically treated water and the non-magnetically treated water was confirmed by an experiment using a kettle, and it took 11 minutes and 13 seconds to boil 1 liter of water without magnetic treatment. It was confirmed that the efficiency of the magnetically treated water was 10 minutes and 43 seconds, and the efficiency was increased by about 4.5%. This is considered to contribute to the thermal efficiency of boilers and the like. The magnetic force at the center of the pipe of the water quality improving device 10 used in this experiment is 14
The flow rate is 50 gauss, the flow rate is 0.4 m / sec, and the water pressure is 2.1 kg / cm ² .

Experiments have also been conducted to examine the concentration of ammonia in the chicken manure of the hens raised in magnetically treated water. In this experiment, 300 g of chicken dung of 280-day-old hens kept for one month in magnetically treated groundwater and 300 g of 280-day-old hens kept in non-magnetically treated groundwater were sealed in a plastic bag, The ammonia concentration after 7 hours was measured. According to this experiment, it was confirmed that the concentration of ammonia in the chicken droppings of the hens cultivated in the non-magnetically treated groundwater was 56PPM, whereas the concentration of the chicken droppings of the hens raised in the magnetically treated groundwater was 3PPM. It was This makes it possible to suppress the chicken manure odor in the poultry house as well as the adverse effects of ammonia on the hens.

A comparative test was also conducted between a test group of hens bred in magnetically treated tap water and a control group of hens bred in non-magnetically treated tap water. 0.15% for 56 days of 56 days, 0.34% for 75 days of 28 days to 103 days, 1 day to 9%
In the 91 days of the 1-day age, 0.4% was superior in each test section. In addition, the spawning rate is 82.5% in the test zone on average over the period,
The control area 81.7% and the 0.8% test area are superior,
In particular, remarkable growth occurs during a high temperature period when the house temperature is around 30 ° C.
Also in terms of egg weight, the test group was also superior in average by 1.28 g during the period. In addition, the Hau unit (high egg white coefficient) was also excellent in the test group by 1.08. The magnetic force at the center of the pipe 11 of the water quality improving device 10 used in this test is 1300 gauss, the flow velocity is 0.4 m / sec, and the water pressure is 1.1 kg / cm ² .

Since the magnetically treated water also has improved thermal conductivity, it is installed in a boiler, a hot water supply system, a heat exchanger, a humidifier, a steam generator, a booster heater, a solar system, in-plant piping, a pool and a bath. As a result, heat exchange is improved and the generation of scale and sludge can be suppressed.

Further, by installing a water quality improving device in the cooling tower (cooling lamp), it is possible to prevent the generation of scale due to carbonates, and it is possible to save the chemicals for preventing the generation of slime due to algae / bacteria, and the number of cleanings And, the time can be shortened, the efficiency of the equipment can be promoted, and the life of the equipment can be extended. In addition to this, it may be used for an engine radiator or a refrigerator.

Further, since the magnetically treated water has a high dissolving power and dispersibility, the clusters of the liquid medicine and liquid fertilizer become small, and the water can be uniformly dissolved. Furthermore, since it is highly permeable and activated, the effect of chemicals and liquid fertilizer is increased by foliar application. It has been confirmed by experiments that the effect does not deteriorate even if the pesticide is diluted by 25% from the normal magnification. Therefore, cultivation of greenhouses, open field cultivation, hydroponic cultivation, etc., or the use of magnetically treated water as water for irrigation, drip, and circulation improves the rooting of vegetables, fruit vegetables, flowers, etc., and grows vigorous plants. can do. For example, it is used for strawberries, cucumbers, tomatoes, soft vegetables, and flowers such as symbidium, dendroe, phalaenopsis, cattleya, roses, cyclamen, eustoma, and has been confirmed to improve quality and yield.

In addition, it has been confirmed that, as an effect of the magnetically treated water, the activity of microorganisms in the animal body is activated, digestion, absorption and decomposition are improved, and the absorption amounts of vitamins A and E are also increased. , May be used for water for fish farming, eel cultivation and livestock farming.

Further, by using it in a general household and magnetically treating tap water, it is effective in improving stain removal in washing, improving heat efficiency of water heaters, preventing yellowing of toilets, and preventing stains and odors from drains. is there. In addition, since activated and ionized water is good for health, it can be used as drinking water.

In this way, the water quality improving device 30 is placed sideways, so that the stability is improved. Therefore, it can be prevented from falling due to a gust of wind when placed outdoors, for example. In addition, the same code | symbol is attached | subjected to the part corresponding to the water quality improvement apparatus 10 shown by FIGS.

Further, the pipe line 11 of the water quality improving device 30 is formed in a cylindrical shape, and both ends of the pipe line 11 are connected to a short cylindrical intake port 15 and a discharge port 16 via pipe joints 31, respectively.
Intake 15 and outlet 1 from the housing 12
One end of 6 is provided so as to project from the housing 12, and is fixed to the housing 12 in a liquid-tight manner. Since each of the pipe line 11, the intake port 15, the discharge port 16 and each pipe joint 31 is made of a non-magnetic material such as vinyl chloride,
It is made lightweight.

The holding means 13 for holding the permanent magnet 19, the pipe line 11, the intake port 15 and the discharge port 16 are fixed inside the housing 12 to the bottom 32 of the housing 12.

The surfaces of are parallel to each other. Therefore, the water quality improvement device 3

FIG. 6 is a plan view showing a water quality improving device 40 according to a third embodiment of the present invention, FIG. 7 is a bottom view of the water quality improving device 40, and FIG. 8 is a part of the water quality improving device 40. 9 is a vertical cross-sectional view of a part of the water quality improvement device 40.

The water quality improving device 40 is housed and held in the casing 41, and a pair of casings 41a and 41b (hereinafter sometimes abbreviated as the casing 41) which are box-shaped holding means having one opening. And a permanent magnet 45. Each casing 41a, 41b has a bottom wall 54
a and 54b are connected by a pair of hinges 43 so as to be angularly displaceable, and upper walls 55a and 55b of the casing 41 are connected.
A pair of locking means 44 is provided on each of the casings 41.
The casings 41a and 41b can be held in a closed state by facing and locking the openings of the casings 41a and 41b.

The casing 41 is composed of a rod-shaped casing body 50 having a substantially U-shaped cross section, and side walls 46 covering both side portions in the longitudinal direction of the casing body 50. The side wall 46 is a screw formed integrally with the casing 41. It is pinched and fixed by the screw hole 53 of the hole member 57 and the bolt 52.
The casing 41, the hinge 43 and the locking means 44 are each made of a non-magnetic material such as austenitic stainless steel. Semicircular cutouts 47 are formed in both side walls 46 of the casings 41 and 42, and the cutouts 47 become a perfect circle when the casings 41a and 41b are closed. As shown in FIG. 9, in the permanent magnet 45, for example, three plate-shaped permanent magnets are stacked on the yoke 48 in the casing 41 by magnetic attraction. Such a permanent magnet 45 projects inward from the bottom wall 54 and the top wall 55 in the casing 41,
It is sandwiched and held between a pair of locking members 64 provided along the longitudinal direction and a screw hole member 57 provided on the rear wall 56.

A rubber hose 61, which is a conduit made of a non-magnetic material, is interposed between the casings 41 and 42 along the longitudinal direction to close the casings 41 and 42, so that the rubber hose 61 is provided with notches 47 and permanent magnets. It is sandwiched by each surface 45a of 45. Permanent magnet 45
Is selected to be larger than the diameter of the notch 47, and the magnetic field can be applied to all the water to be treated passing through the rubber hose 61. When the outer diameter of the rubber hose 61 is small, the rubber hose 61 is mounted by winding a non-magnetic material such as vinyl tape. Even in this case, the magnetic field acts on all the water to be treated passing through the rubber hose 61.

Permanent magnet 4 held in casing 41
5 are arranged in pairs so that different magnetic poles face each other on a straight line perpendicular to the axis of the rubber hose 61.
It is possible to prevent the magnetic field at the center of 1 from becoming weak. For example, three pairs of such permanent magnets 45 are provided, and the permanent magnets 45 arranged in pairs have mutually facing surfaces 45a which are parallel to each other, whereby the magnetic field is effectively applied to the water to be treated passing through the rubber hose. Can be operated.

With this structure, water can be easily subjected to magnetic treatment by mounting the water quality improving device 40 on the rubber hose 61 or the pipe made of a non-magnetic material. The length L of the water quality improving device 40 is selected to be, for example, 290 mm, and the diameter D of the notch 47 is, for example, 2
It is selected to be 6.5 mm.

FIG. 10 is a perspective view showing a water quality improvement device 60, which is a fourth embodiment of the present invention, with a part thereof cut away.
The water quality improving device 60 is similar to the water quality improving device 40 shown in FIGS. 6 to 9, and it should be noted that the plurality of thin plate-shaped permanent magnets 45 provided in the casing 41 are close to the rubber hose 61 to be mounted. The permanent magnets 45 are held by the casings 41 and 42 so as to be displaceable in the separating direction 62 and in the longitudinal direction 63 of the casing 41 which is substantially perpendicular to the approaching / separating direction 62 and along the pipe axial direction of the pipe to be mounted. Means that they are provided at intervals of ΔL in the longitudinal direction 63.

Each of the permanent magnets 45 housed in the casing 41a is arranged so that the N pole side faces the rubber hose 61, and each of the permanent magnets 45 in the casing 41b faces the S pole side of the rubber hose 61. Both side walls of each of the permanent magnets 45 are arranged in contact with the bottom wall 54 and the top wall 55 of the casing 41 so as to be slidably supported.
Therefore, when the casings 41a and 41b are closed, the permanent magnet 45 housed in the casing 41a and the permanent magnet 45 housed in the casing 41b are attracted to each other by a magnetic attraction force and are locked by the locking piece 64. . Further, between the permanent magnet 45 and the back wall 56, an elastic support piece 58 having elasticity, such as rubber, supports the permanent magnet 45 so as to be displaceable in the approaching / separating direction 62 and the longitudinal direction 63.

Since the permanent magnets 45 in the casing 41 are arranged so that the same poles are adjacent to each other, the adjacent permanent magnets 45 have an equal interval ΔL in the casing 41 due to the magnetic repulsive force. And then stored. Further, since the respective permanent magnets 45 held in the casings 41 and 42 are held so as to be displaceable in the longitudinal direction 63, the permanent magnets 45 facing each other when the casing 41 is closed are made to come closest to each other by the magnetic attraction force. In other words, the magnetic field uniformly acts on the water to be treated in the rubber hose because the displacement is made, that is, the rubber hose 61 is displaced so as to oppose on a straight line perpendicular to the axis of the rubber hose 61. The magnet on the axis of the rubber hose 61 is selected to be, for example, about 1500 gauss.

In this way, each permanent magnet 45 is displaceable in the approaching / separating direction 62 and the longitudinal direction 63 in the casing 4.
Since the rubber hoses 61 are held by Nos. 1 and 42, for example, even if the rubber hose 61 is bent while being attached to the water quality improving device 60, each permanent magnet 45 can be displaced following the displacement of the rubber hose 61. Even if the rubber hose 61 is displaced in this way, the permanent magnets 45 supported by the casing 41 maintain substantially equal intervals, and a substantially uniform magnetic field can be applied to the water to be treated. Further, even if the permanent magnets 45 are mounted on a pipe such as a pipe made of a non-magnetic material that bends or bends, the permanent magnets 45 are displaced according to the bending and bending, and the permanent magnets 45 always apply an optimum magnetic field to the pipe. Can be made.

FIG. 11 shows the permanent magnet 45 of the water quality improving device 60.
FIG. 6 is a simplified perspective view showing another holding method of FIG. Two insertion holes 70 are formed in each of the permanent magnets 45, and two cords 71 having flexibility and made of a non-magnetic material are inserted in each of the insertion holes 70 in each of the permanent magnets 45. Both ends of the cord 71 are fixed to both side walls 46 of the casing 41, respectively. In this way, each permanent magnet 45 moves in the approaching / separating direction 6
2 and the casings 41 and 4 displaceable in the longitudinal direction 63
2 is held by the casing 41 due to vibration or the like.
It is possible to prevent the permanent magnet 45 from coming loose inside.

FIG. 12 is a simplified perspective view showing still another method of holding the permanent magnet 45 of the water quality improving device 60. Triangular prism-shaped notches 73 are formed at both ends of the permanent magnet 45. A pair of triangular prism-shaped holding rails 72, which are fitted in these notches 73 in the casing 41 and have flexibility and elasticity, and which are made of a non-magnetic material, are provided on the bottom wall 54 and the upper wall 55 of the casing 41. It is provided in the casing 41 along the direction 63. Holding rail 72
Since only both end portions are fixed to both side walls 46 of the casing 41, each permanent magnet 45 is held so as to be displaceable in the approaching / separating direction 62 and the longitudinal direction 63.

With such a structure, even if the rubber hose 61 to be mounted holds the permanent magnet 45 without being distorted and is bent or mounted on a pipe made of a curved or bent non-magnetic material, these bends Further, it is possible to allow the bending and allow the magnetic field to effectively act on the water to be treated in the pipeline.

FIG. 13 is a simplified sectional view showing a water quality improving device 80 according to a fifth embodiment of the present invention. The north pole and the south pole of the permanent magnet 81 of the water quality improving device 80 are formed in a ring shape so as to face each other substantially in parallel, and a conduit 82 made of a non-magnetic material is arranged between these magnetic poles. With such a ring-shaped permanent magnet 81, the magnetic field is most efficiently supplied to the conduit 8.
2 can act on the water to be treated.

Further, each of the above-mentioned magnetic improvement devices 10, 40,
50 and 80 are not limited to water, but may be used for fuel oil such as gasoline, light oil, and heavy oil.

[0055]

As described above, according to the present invention, since the permanent magnets are provided so that the magnetic poles different from each other face each other so as to sandwich the pipe line, the magnetic field does not become weak at the central portion of the pipe line, and The water to be treated can be surely subjected to magnetic treatment.

Further, since each of the permanent magnets is provided so as to be displaceable in the approaching / separating direction and the longitudinal direction, it is possible to allow the displacement of the conduit to effectively apply the magnetic field to the water to be treated.

Since the surfaces of the permanent magnets facing each other are substantially parallel to each other, the magnetic field can be applied to the water to be treated substantially evenly.
