Description

  The present invention relates to a purification device for treating dirty water such as aquaculture ponds such as salmon and ponds for home appreciation fish to maintain water quality.

  Conventionally, water in aquaculture ponds and household ornamental fish ponds are contaminated with bacteria over time due to leftover food, excrement, scales, algae, etc. of the fish to be reared and the water quality deteriorates. Therefore, it is necessary to improve the water quality, but it is inefficient to frequently replace and clean the water in the pond, and water quality treatment with chemicals etc. is difficult to handle and may affect fish growth. . In addition, the environment may be adversely affected. For this reason, it is common to treat sewage with a purification device and circulate and use the purified water. Moreover, in the processing method of the purification apparatus which purifies the water of a pond, it is common to filter and purify water with filters having various materials and structures.

  On the other hand, since the piping for circulating water flows contaminated water, scales due to pollutants, organic substances due to microorganisms, and the like adhere to the piping walls due to pollutants in the water. As a method of performing this scale adhesion prevention treatment, a method of performing electromagnetic field treatment as described in Patent Documents 1 to 3 is known. For example, in Patent Documents 1 and 3, an electric wire is wound around a pipe in a coil shape, a current whose frequency changes is supplied to the coil by a dedicated power source, and an electric field and a magnetic field that change with time are generated around the coil. An electromagnetic field processing apparatus is disclosed. Thus, the generated electric field or magnetic field electromagnetically treats the water flowing in the pipe, and prevents the scales due to the substances in the fluid from adhering to the inside of the pipe.

Further, Patent Document 2 discloses a treatment method for improving water quality by treating water with an electromagnetic field and preventing rust and piping, that is, ammonia odor and the like.

  In the above-described conventional technology, a method of filtering water using a filter that is a general method for purifying water in a pond requires regular cleaning or replacement of the filter for filtering water, which is costly. Moreover, since the purification apparatus using a filter is formed by a filter and a pipe for circulating water over and over, the space efficiency is not good. Further, the filter cleaning operation and the filter whose lifetime has been exhausted are discarded as garbage, and depending on the material, a fine separation operation or the like is required, which is troublesome together with the cleaning operation.

  In addition, since scales and organic substances due to water pollutants adhere to the inside of the pipe through which water is circulated, it is necessary to periodically remove the scale inside the pipe. The adhesion of the scale can be prevented by performing electromagnetic field processing with the devices disclosed in Patent Documents 1 to 3. However, in addition to the purification device, there is a problem that an installation space for the device is required.

  The present invention has been made in view of the above-mentioned problems of the prior art. It has a simple structure and is efficient in space, does not require time and effort for cleaning the filter, does not generate dust due to filter replacement, and the like. Another object of the present invention is to provide a purification device that suppresses water contamination and sterilizes and purifies it.

In the present invention, two electric wires each coated with insulation are wound in the same winding direction on the outer side of one tube through which water to be treated flows and adjacent to the longitudinal direction of the tube. Of the two electric wires forming the two coil portions, the electric wire forming one coil portion is linear in the longitudinal direction of the tubular body outside the other coil portion. An electric wire extending along the other coil portion extends linearly in the longitudinal direction of the tubular body on the outside of the one coil portion, and the two electric wires forming the respective coil portions. The pair of end portions located on one side along the longitudinal direction of the tubular body are connected to a pair of terminals of a commercial power source, respectively, and the two electric wires forming the coil portions, A pair of each end located on the same other side along the longitudinal direction of the tube body Are respectively connected to a pair of terminals of the appliance, the in each coil unit and an alternating current is supplied by the commercial power supply to the coil unit current flows in another different winding direction around the electromagnetic field thereby inducing the It is the purification apparatus applied to the to-be-processed water which flows through a pipe body.

  According to the purification apparatus of the present invention, installation space is not required, piping efficiency is good, functions such as sterilization and disinfection of water to be treated, and decomposition of organic substances are exhibited, and troubles such as filter cleaning are not required. Furthermore, no dust is generated due to filter replacement, etc., power consumption is extremely low, and water contamination can be reliably prevented.

  Hereinafter, an embodiment of the purification apparatus of the present invention will be described with reference to FIGS. The purification apparatus of this embodiment is used as a purification apparatus that suppresses deterioration of water quality such as aquaculture ponds.

  As shown in FIG. 1, the purification device 2 of this embodiment includes two wires covered with an insulator on a straight tubular magnetic metal tube 4 having an appropriate length to be used such as a water pipe. 6 is wound. The two electric wires 6 are wound on the outer side of the tubular body 4 in the same winding direction so as to divide the tubular body 4 into two, respectively, approximately the same number of 100 times or more, and the two coil portions 8a, 8b is formed. The two coil portions 8a and 8b are formed at a substantially central portion of the tubular body 4 with an appropriate interval.

  The portion of the electric wire 6 where the coil portion is not formed is an electric wire in which the electric wire 6 having the coil portion 8a extends linearly in the longitudinal direction of the tubular body 4 outside the coil portion 8b to form the coil portion 8b. 6 extends along the linear direction in the longitudinal direction of the tubular body 4 on the outer side of the coil portion 8a. Resin tubes 14 are attached to both ends of each electric wire 6 in the vicinity of both end portions 12a and 12b of the tube 4.

  Further, both ends 12a and 12b of the tube body 4 are made of a metal tube body 4, a short auxiliary tube 16 made of a vinyl chloride resin having the same inner diameter and different outer diameter as the tube body 4, and an end made of vinyl chloride resin. It is fitted by the part mounting part 18. The end mounting portion 18 has an inner diameter that is substantially equal to the outer diameter of the metallic tube body 4, the outer diameter of the portion that is attached to the tube body 4 is slightly thicker, and has a step on the outer periphery. Furthermore, the end portion of the resin tube 14 is fixed to the end portion attachment 18 in an appropriate position around the end portion attachment 18 of the both end portions 12 a and 12 b in a state parallel to the longitudinal direction of the tube body 4. And the tubular body 4, coil part 8a, 8b, and both ends 12a, 12b are accommodated in the outer cylinder 10 made from a vinyl chloride, and the both ends opening of both ends of the tubular body 4 is opened in both ends 12a, 12b. It is formed.

  Here, the principle which suppresses the contamination of water with the purification apparatus 2 of this embodiment is demonstrated. For example, in pipes through which fluids such as domestic wastewater flow, scales and other organic substances adhere to the pipe inner wall, and the attached scales become a hotbed for microorganisms such as bacteria, and the activities of these bacteria and microorganisms cause water quality deterioration. It has become.

  Therefore, in order to suppress the deterioration of water quality, the fluid to be treated such as water flowing in the pipe is subjected to electromagnetic field treatment. Electromagnetic field treatment is to induce an electromagnetic field in a coil by causing an electromagnetic field induced current to flow in a coil provided outside the tubular body constituting the fluid flow path, thereby generating a magnetic field and an electric field in the tubular body, The magnetic energy and the electric energy of the electric field give electric field energy to the fluid flowing in the tubular body using the fluid molecules and ions in the fluid as a medium.

  As a result, as one phenomenon, both the scale surface and the inner surface of the tube are strongly negatively charged, so the scale and tube inner surface in the fluid are repelled to prevent the scale from adhering to each other and to connect the scales together. It inhibits and prevents crystallization. Further, by reducing the surface tension of the fluid and minimizing the water cluster, water is infiltrated into the scale crystal to be small crystallized. Thus, according to the electromagnetic field-treated water, it is difficult to attach scales and increase the size of crystals. For this reason, for example, it is difficult to attach scales (Ca, Mg, etc.) that serve as nutrient sources and breeding grounds for microorganisms and to increase the size of crystals, so that the growth of microorganisms can be suppressed and deterioration of water quality can be suppressed. Become.

  Next, the operation and action of the purification device 2 of this embodiment will be described. In this embodiment, as shown in FIG. 2, two coil portions 8 a and 8 b are wound around the tubular body 4, and one end portion of a pair of electric wires 6 forming the coil portion is connected to a power source 20. Is connected to other electric appliances such as a pump motor 22. When the motor 22 is switched on to operate the motor 22 from the power source 20, commercial alternating current flows through the coil portions 8 a and 8 b by the electric wire 6. Then, the alternating current that operates the motor 22 first flows through the two coil portions 8a and 8b, and the magnetic field 24 and the electric field are generated inside the tube body 4 inside each of the two coil portions 8a and 8b. 26 is generated, and the fluid flowing inside the tube 4 is subjected to electromagnetic field treatment by the generated magnetic field 24 and electric field 26. At this time, the fluid flowing from the opening 4a of the tubular body in FIG. 2 is subjected to electromagnetic field treatment and flows out from the tubular body opening 4b.

  Next, the usage method of this purification apparatus 2 is demonstrated. First, the purification device 2 shown in FIG. 1 is joined and installed in the middle of a pipe for circulating and purifying water in the aquaculture pond. Next, the end of the electric wire 6 of the purification device 2 is connected to a commercial power source by an unillustrated outlet or the like, and the other end of the electric wire 6 is connected to a terminal of a motor 22 of a pump (not shown) that circulates water. Then, when the pump motor 22 is activated by the alternating current flowing from the commercial power source, the water in the pond circulates in the tubular body 4, and the current flows through the coil portions 8a and 8b by the electric wire 6, and the two coil portions 8a, A magnetic field 24 and an electric field 26 are generated inside the tubular body 4 inside each 8b.

  According to the purification device 2 of this embodiment, the dedicated power source is not used for supplying current to the two coil portions 8a and 8b of the purification device 2 and is connected in series to an electric wire that supplies commercial power to a pump or the like. It just needs to be done and consumes very little energy. This eliminates the need for a space for a dedicated power source, which improves the space efficiency. Further, after installation, maintenance such as cleaning and periodic inspection is not required, which is troublesome. Experimentally, the water in the pond that was soiled with organic matter became clear and beautiful in a few days, and the breeding of beautiful algae became active. Furthermore, since bacteria and viruses are sterilized, disease deaths such as cultivated silkworms are eliminated, and health is improved.

  In addition to the metal tube, the tube used in the purification apparatus of the present invention may use a vinyl chloride tube although the magnetic field is weak, and the thickness and length of the tube can be appropriately selected. Moreover, the thickness of the electric wire wound around the tubular body to form the coil portion and the material of the covering can be selected as appropriate. Further, the number of turns of the coil portion is not limited to the above embodiment, and can be set as appropriate.

  In addition, since the coil part should just be formed in the outer side of a tubular body, the tubular body may be curving in the clearance gap part of two coil parts.

  Tables 1 and 2 list the inspection results of the water quality of the pond when the purification device 2 according to one embodiment of the present invention is used. It is common to use groundwater as the water used in the aquaculture pond. For this reason, the well water used for pond water and the water collected from the pond are inspected. The quality of the well water used in the pond and the results of the pond water circulating through the purification device are as shown in the table.

  Table 1 shows potable well water, and Table 2 shows the water in the culture pond that is being recycled. This water quality test was commissioned by the Toyama Prefectural Chubu Welfare Center.

  According to the results of the water quality test, the CFU values of general bacteria in Table 2 are slightly increased compared to Table 1, but other values are slightly increased or hardly changed. Furthermore, it was confirmed that the water quality remained low compared to the water quality reference value described in parentheses below each value in the table. As is clear from this result, according to the purification apparatus of this embodiment, the progress of contamination is hardly seen, and the water contamination is sufficiently suppressed. The CFU values in Tables 1 and 2 are values representing the number of colonies (colonies) of bacteria that can be visually confirmed.

  In Tsugaike with this purifying device, one or two moths that had been killed in the month so far have not been killed by moths for two months after installation. was gotten.
