A fixed cylindrical body made of iron-nickel alloy is fitted and fixed to an AC magnetic field generator formed in a cylindrical shape, and a rotating cylindrical body made of iron-nickel alloy is coaxially arranged on the fixed cylindrical body and generates an alternating magnetic field. A copper wire as an electromagnetic wave derivative was inserted in the longitudinal direction at the axial center position of the body, and an alternating current was induced in the copper wire in conjunction with the rotational drive of the rotating cylinder.

The configuration of the present invention will be described in detail with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a water quality improvement device. The water quality improvement device 1 includes a coil 3 wound around an outer peripheral surface of a pipe 2 through which a liquid to be treated flows, and connection ends provided at both ends of the coil 3. 3a and 3b are provided with a drive mechanism 4 for outputting an AC signal, and are configured to remove the scale adhering to the inside of the piping pipe 2 and prevent its adhesion.

The drive mechanism 4 has a cylindrical shape in which a plurality of permanent magnet elements 5b, 5b... Are embedded in a periodic arrangement in different magnetization directions (indicated by arrows in FIG. 3C) on a base 5a formed of silicon resin. Iron nickel nickel in which the alternating magnetic field generator 6 is fitted and fixed to a copper hollow pipe 7 having both end faces 7a and 7a sealed, and a plurality of holes 8a, 8b and 8c having different large and small diameters are randomly formed. An alloy-made fixed cylindrical body 8 and a rotating cylindrical body 9 made of iron-nickel alloy in which a plurality of holes 9 a, 9 b, 9 c having different large and small diameters are randomly formed are coaxially arranged in the alternating magnetic field generator 6. The copper wire 10 is inserted in the longitudinal direction into the axial position of the hollow pipe 7 in the longitudinal direction, and is connected to the rotational drive of the rotating cylinder 9 to connect the copper wire 10. An alternating current is induced in the.

In other words, the alternating magnetic field generator 6 is disposed so as to be sandwiched between frame rings 11 and 11 that are fitted and fixed to the end edge of the hollow pipe 7, and is arranged on the inner peripheral surface of the alternating magnetic field generator 6. The fixed cylindrical body 8 whose surface is faced is similarly clamped between the frame rings 11 and 11, and the rotating cylindrical body 9 is an annular bearing with a predetermined gap inside the fixed cylindrical body 8. It is rotatably arranged via B and B.

The rotating cylinder 9 is configured by coaxially fitting rings 12a and 12b to the inner surfaces of the peripheral edge portions at both ends, and the receiving groove portion 12c is formed on the inner periphery of one of the rings 12b. Is provided around the end surface 7a of the hollow pipe 7, and a pulse motor 13 whose rotation speed can be varied in a range of 100 rpm to 1000 rpm by a control signal from a control unit (not shown) is disposed. The rotary cylinder 9 is driven to rotate by engaging the receiving groove 12c with the drive gear 13a.

On the other hand, as shown in FIG. 6, the coil 3 has a flexible film substrate 3 d having a pattern surface 3 c that gradually expands outward in the shape of the center from one connection end 3 b (coil end 3 b). It is formed by printing on it. Then, as shown in FIG. 7, the coil 3 has a cover body 14 made of silicon resin formed in an inverted U shape in cross section, with the coil 3 placed along the upper surface or the lower surface of the pipe 2. If the fitting recess 14a of the body 14 is fitted and fixed, the water quality improvement device 1 can be easily installed and removed at any installation location of the pipe 2 without permanently installing the coil 3 at a predetermined position. become.

Since the first embodiment is configured as described above, when a control signal is sent to the pulse motor 13 from a control unit (not shown), the rotational drive of the pulse motor 13 is started and the rotating cylinder of the drive mechanism 4 is started. The body 9 is driven to rotate. At this time, with respect to the alternating magnetic field generated by the alternating magnetic field generator 6, a plurality of holes 8 a, 8 b... Randomly formed in the fixed cylinder 8 and the rotating cylinder 9 are randomly formed. The polymerization with the plurality of holes 9a, 9b... And the release of the polymerization are continuously performed over time, and as a result, the alternating magnetic field is repeatedly blocked and passed through the fixed cylinder 8 and the rotating cylinder 9. It will be.

When an alternating magnetic field passes through the copper wire 10 inserted through the axial center position of the hollow pipe 7, an electromotive force is generated in the copper wire 10, and at the same time, the electromotive force flows through the copper wire 10 to generate a magnetic field. When the alternating magnetic field is repeatedly blocked and passed, an alternating electromagnetic field induced current with a deviated wavelength is transmitted to the copper wire 10.

As described above, the electromagnetic field induced current induced in the copper wire 10 is applied as it is between the connection ends 3a and 3b of the coil 3, and an electromagnetic field is induced to generate a magnetic field and an electric field in the pipe 2; Electrolytic energy is applied to the liquid to be processed that circulates in the pipe pipe 2 by the magnetic energy and the electronic energy of the electric field, using the liquid molecules and ions in the liquid to be processed as a medium.

And the to-be-processed liquid by which the electromagnetic field process was carried out electrically charged the outer surface and inner surface of the piping pipe 2 containing the scale factor contained negatively, and the electromagnetic field induced current supplied to the coil 3 is the hole of the fixed cylinder 8 The polymerization of 8a, 8b ... and the holes 9a, 9b ... of the rotating cylinder 9 and the release of the polymerization are continuously performed over time, thereby causing a magnetic flux change accompanying a time series change (modulation) of the frequency, An induction electric field due to induction electric field energy is formed in the pipe 2 and a high eddy current is generated.

That is, the scale factor in the liquid to be treated that circulates in the normal piping pipe 2 is attached to the inner surface of the piping pipe 2 that is slightly negatively charged by the ground because the surface has a positive charge. However, by the electromagnetic field treatment using the high eddy current, the surface of the scale factor is ionized with a negative charge, and the inner surface of the pipe pipe 2 has a strong negative charge, so that the surface of the scale factor and the pipe pipe Both the inner surfaces of 2 are strongly negatively charged, and the scale factor and the inner surface of the pipe 2 are strongly repelled.

Therefore, the scale factor can be detached from the inner surface of the pipe 2 due to the repulsion between the scale factor and the inner surface of the pipe 2, and the scale factor can be prevented from adhering to the inner surface of the pipe 2.

In addition, by applying a strong negative charge to the surface of the scale factor by the electromagnetic field treatment, the formation of large particles due to the coupling of the scale factors is prevented, and the surface tension of the liquid to be treated is reduced to reduce the water cluster. By making particles, water can penetrate into the scale factor and dissolve into small crystals, and the scale factor is re-crystallized into smaller crystals by recrystallizing the scale into smaller crystals. It can be prevented from adhering to the inner surface.

According to the experiment, the specific configuration of the drive mechanism 4 is as follows: 1. alternating magnetic field generator (silicone resin thickness: 5 mm) 2. fixed cylinder (thickness: 0.1 mm) 3. rotating cylinder ( (Thickness: 0.1 mm) 4. Copper wire (wire diameter: 1.25 mm) 5. Alternating magnetic field generator (at the axial center position of 5000 gauss or more) 6. Rotating speed of rotating cylinder: best with requirements of 100 rpm to 1000 rpm The scale factor withdrawal effect was observed.

On the other hand, the generation mechanism of red rust caused by the liquid to be treated in the conventional piping pipe will be described. Chlorine as a disinfectant contained in tap water erodes the inner surface of the piping pipe 2 so that the iron content of the piping pipe 2 is covered. It dissolves as Fe ^{2+ in the} treatment liquid, and iron ions react with the alkali in the treatment liquid to form Fe (OH) _2, and the Fe (OH) ₂ is dissolved with dissolved oxygen in the treatment liquid. It reacts to form 2Fe (OH) ₃ , and this 2Fe (OH) ₃ is further oxidized to form Fe ₂ O ₃ (red rust).

For the red rust (Fe ₂ O ₃ ) generated as described above, an induction electric field is formed in the piping pipe 2 by applying a strong negative charge to the inner surface of the piping pipe 2 by the electromagnetic field treatment of the liquid to be processed. Thus, the piping pipe 2 maintains a strong reduced state on the inner surface thereof. And, on the inner surface of the pipe 2 in this reduced state, the negative rust (Fe ₂ O ₃ ) releases O ₂ due to the negative charge, resulting in harmless black rust (Fe ₃ O ₄ ) is formed, and therefore, the oxidation of the inner surface of the pipe 2 due to dissolved oxygen in the liquid to be treated can be prevented, and corrosion can be prevented.

Next, Example 2 will be described in detail. The same components as those in the first embodiment will be described with the same reference numerals. 8 to 11, reference numeral 15 denotes a water quality improvement device, which is provided at both ends of the coil 3 wound around the outer peripheral surface of the pipe 2 through which the liquid to be treated flows. The connecting end 3a, 3b is provided with a drive mechanism 16 for outputting an AC signal, and is configured to remove the scale adhering to the inside of the pipe pipe 2 and prevent its adhering.

The drive mechanism 16 includes a cylindrical alternating magnetic field generator 6 in which a plurality of permanent magnet elements 5b, 5b... Are embedded in a periodic arrangement in different magnetization directions in a base body 5a formed of silicon resin. 7a is sealed in a copper hollow pipe 7, and a plurality of slits 17a are formed in the circumferential direction. A fixed cylindrical body 17 made of iron-nickel alloy and a plurality of slits 18a are formed in the circumferential direction. A vibration cylinder 18 made of a nickel alloy is arranged coaxially in the alternating magnetic field generator 6, and a copper wire 10 as an electromagnetic wave derivative is elongated at the axial center position of the hollow pipe 7. An alternating current is induced in the copper wire 10 in connection with the longitudinal swing drive of the vibrating cylinder 18.

In other words, the alternating magnetic field generator 6 is disposed so as to be sandwiched between frame rings 11 and 11 that are fitted and fixed to the end edge of the hollow pipe 7, and is arranged on the inner peripheral surface of the alternating magnetic field generator 6. Similarly, the fixed cylindrical body 17 whose surface is faced is sandwiched coaxially between the frame rings 11 and 11, and the vibration cylindrical body 18 has a buffer 18 b with a predetermined gap inside the fixed cylindrical body 17. , 18b are arranged to be freely slidable.

The vibration cylinder 18 is configured by fitting rings 19a and 19b coaxially on the inner surfaces of the peripheral edges of both ends, and the ultrasonic vibration is provided on the inner periphery of one of the rings 19b. The distal end portion 20a of the child 20 is fixed, and an ultrasonic generator 21 having an amplitude of 300 times / second is disposed on the end surface 7a of the hollow pipe 7 by a control signal from a control unit (not shown). The vibration cylinder 18 is driven to swing in the longitudinal direction via the ultrasonic transducer 20.

On the other hand, as shown in FIG. 6, the coil 3 has a flexible film substrate 3 d having a pattern surface 3 c that gradually expands outward in the shape of the center from one connection end 3 b (coil end 3 b). It is formed by printing on it. Then, as shown in FIG. 7, the coil 3 has a cover body 14 made of silicon resin formed in an inverted U shape in cross section, with the coil 3 placed along the upper surface or the lower surface of the pipe 2. The fitting recess 14a of the body 14 is fitted and fixed.

Since the second embodiment is configured as described above, when a control signal is sent from the ultrasonic generator 21 to the ultrasonic transducer 20, the drive mechanism 16 is passed through the tip 20a of the transducer 20. The vibrating cylinder 18 is driven to swing in the longitudinal direction. At this time, with respect to the alternating magnetic field generated by the alternating magnetic field generator 6, the polymerization of the plurality of slits 17 a of the fixed cylindrical body 17 and the plurality of slits 18 a of the vibrating cylinder 18 are continuously performed and the polymerization is released. As a result, the alternating magnetic field is repeatedly blocked and passed through the fixed cylinder 17 and the vibrating cylinder 17.

When an alternating magnetic field passes through the copper wire 10 inserted through the axial center position of the hollow pipe 7, an electromotive force is generated in the copper wire 10, and at the same time, the electromotive force flows through the copper wire 10 to generate a magnetic field. When the alternating magnetic field is repeatedly blocked and passed, an alternating electromagnetic field induced current with a deviated wavelength is transmitted to the copper wire 10.

As described above, the electromagnetic field induced current induced in the copper wire 10 is applied as it is between the connection ends 3a and 3b of the coil 3, and an electromagnetic field is induced to generate a magnetic field and an electric field in the pipe 2; Electrolytic energy is applied to the liquid to be processed that circulates in the pipe pipe 2 by the magnetic energy and the electronic energy of the electric field, using the liquid molecules and ions in the liquid to be processed as a medium.

And the to-be-processed liquid by which the electromagnetic field process was carried out electrically charged the outer surface and inner surface of the piping pipe 2 containing the scale factor contained negatively, and the electromagnetic field induction current supplied to the coil 3 is the slit of the fixed cylinder 17 The superposition of 17a and the slit 18a of the vibrating cylinder 18 and the release of the superposition are continuously performed over time, so that a magnetic flux change accompanying a time series change (modulation) of the frequency is generated and induced in the pipe 2 An induced electric field due to electric field energy is formed, and a high eddy current is generated.

That is, the scale factor in the liquid to be treated that circulates in the normal piping pipe 2 is attached to the inner surface of the piping pipe 2 that is slightly negatively charged by the ground because the surface has a positive charge. However, by the electromagnetic field treatment using the high eddy current, the surface of the scale factor is ionized with a negative charge, and the inner surface of the pipe pipe 2 has a strong negative charge, so that the surface of the scale factor and the pipe pipe Both the inner surfaces of 2 are strongly negatively charged, and the scale factor and the inner surface of the pipe 2 are strongly repelled.

Therefore, the scale factor can be detached from the inner surface of the pipe 2 due to the repulsion between the scale factor and the inner surface of the pipe 2, and the scale factor can be prevented from adhering to the inner surface of the pipe 2.

In addition, by applying a strong negative charge to the surface of the scale factor by the electromagnetic field treatment, the formation of large particles due to the coupling of the scale factors is prevented, and the surface tension of the liquid to be treated is reduced to reduce the water cluster. By making particles, water can penetrate into the scale factor and dissolve into small crystals, and the scale factor is re-crystallized into smaller crystals by recrystallizing the scale into smaller crystals. It can be prevented from adhering to the inner surface.

According to the experiment, the specific configuration of the drive mechanism 16 is as follows: 1. Alternating magnetic field generator (silicon resin thickness: 5 mm) 2. Fixed cylinder (thickness: 0.1 mm, slit width: 0.5 mm) ) 3. Rotating cylinder (thickness: 0.1 mm, slit width: 0.5 mm) 4. Copper wire (wire diameter: 1.25 mm) 5. Alternating magnetic field generator (axial core position over 5000 Gauss) 6. The best scale factor detachment effect was observed with the requirement of the number of repetitions of the vibration cylinder: 300 times / second. The other performances and functions related to the coil 3 are the same as those in the first embodiment, and a description thereof will be omitted.

It can be used not only for wastewater treatment and purification of waterworks but also for outdoor use such as irrigation water.
