Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a live fish transport container using an electromagnetic water treatment device. Specifically, when carrying live fish such as eels over long distances over a long period of time, it is possible to sterilize and purify the water in the aquarium with a simple device so that it can withstand long-term, long-term transportation. At the same time, by attaching a cushioning material to the water tank or providing a rocking prevention means, excessive stress is not applied to the live fish, and the survival rate thereof is increased.

2. Description of the Related Art One of the reasons why our diet has been enriched is the progress of aquaculture technology. Most of the aquaculture is seafood. Eel and eel also belong to this category. Unagi farms are not limited to Japan, but are scattered throughout Southeast Asia. When the source of the young eel is in a foreign country such as Southeast Asia, for example, when it is an eel, it is cultivated from a young eel to an adult eel in a warm area and then shipped to Japan, which is a consumption area. The transport means is an aircraft. In other words, it is imported as air cargo.

[0003] Recently, as an alternative to such an aquaculture form, aquaculture is carried out in a warm area (for example, Southeast Asia) from fry to juveniles, and then transferred to domestic aquaculture farms over a period of weeks to months. Then, by culturing until the eel becomes mature and then transporting it to the consuming region, a culture mode (division of labor) that reduces the total cost is considered.

[0004] When taking such a culture form, a transport container for transporting young eels is required. It may be transported over a considerable distance from a foreign farm to a domestic farm. In consideration of this long-distance transportation, the transportation container needs to be equipped with various processing means such as sterilization, purification, oxygen inhalation, and water temperature adjustment in the aquarium containing the young eel. By storing the young eel for a long time, the water becomes cloudy and oxygen in the water decreases, so if this is left unattended, the young eel will die.
Therefore, at least it is necessary to sterilize or purify the inside of the water tank. It is considered that ozone and chlorine are used for sterilization and purification.

[0005]

The water treatment apparatus using chlorine has sterilizing and decolorizing effects, but it causes a problem of residual chlorine and requires large-scale equipment such as a chlorine gas generator. As a result, equipment costs are high and maintenance is difficult.

In a water treatment device using ozone,
It is known that it has a decolorizing and deodorizing action in addition to the bactericidal action by oxygen-based active species such as ozone, but it requires large facilities such as the generation of ozone odor and the need for ozone generating facilities. Therefore, the equipment cost is high and the maintenance is difficult.

When chlorine is used in this way, the existence of derivative chemical substances due to residual chlorine and chlorine mixing is regarded as a problem, and the recently developed advanced electromagnetic water treatment equipment using ozone or ultraviolet rays It causes problems such as high cost and high maintenance cost.

Therefore, in order to solve such a conventional problem, the present invention uses a small electromagnetic water treatment device so that water treatment can be performed in water, and excessive live fish such as young eels. We propose a live fish transport container that can withstand long-distance and long-term transport without being subject to the stress of.

[0009]

In order to solve the above-mentioned problems, in the live fish transport container according to the present invention as set forth in claim 1, the live fish transport container is installed in a water tank capable of accommodating live fish, and water in the water tank is sucked into the container. Electromagnetic water treatment device that sterilizes and purifies electrolyzed water while mixing with air taken in from the outside, and openable and damp wave damping submerged under the water surface to prevent shaking during transport It is configured to circulate in the water tank while being constituted by an operation lid and an opening / closing lid provided on the outside of the water tank, and water stored in the water tank is sterilized and purified by the electromagnetic water treatment device. It is characterized by

In this invention, an electromagnetic water treatment device is installed in the water tank to sterilize and purify the water tank. By sending the oxygen-based active species obtained by electrolyzing the water component into water, the bacteria contained in the water are sterilized by the oxygen-based active species. By applying an electric field to the water component existing around the organic molecule, the dipole of the water component is oriented in the electric field direction, and the magnetic field causes the water molecule to rotate at high speed. This high-speed rotation causes friction between the organic molecule and the water component. The organic molecules are wet-burned by the high temperature generated by this thermal friction and the active oxygen species.
By this wet combustion, organic matter molecules are incinerated from wastewater to reduce organic matter in the water.

Ions are removed from the surface of the mass of wastewater by applying a magnetic field to the wastewater. A lump of sewage is a substance that causes defecation, swelling, or stains on water (hereinafter collectively referred to as sludge).

The ions bound to the surface of the sludge are
Due to the Lorentz force by the magnetic field, some of the surface ions are stripped off, and the amount of surface ions is reduced. The decrease in the total amount of ions weakens the binding force between the sludge masses, and the sludge is made into fine particles.

In the micronized colloidal particles, ultrafine bubbles generated by the bubble shearing section are discharged inside the water treatment section or outside the electromagnetic water treatment apparatus and suspended in water. Adhere to its surface. The colloidal particles float to the water surface due to the buoyancy of the ultrafine air bubbles.
Water is purified by collecting the floating colloidal particles (scum).

A shock absorbing material is attached to the inner wall surface of the water tank so that the impact is softened even when the water tank hits the inner wall surface. On the surface of the water tank, a wave damping cover (water control plate) is provided in a submerged state. By this inner lid, various fluctuations of water such as long cycle and short cycle in the water tank are suppressed.

Since the stress on the live fish is reduced by these, the damage to the live fish can be reduced even when it is transported over a long distance or a long time in combination with the sterilization and purification action in the aquarium. The transport container is mounted on a freight transport ship, transport truck, etc. and transported to the target farm.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a live fish transport container according to the present invention will be described in detail with reference to the drawings.

In this example, the opening / closing lid 104 has two opening / closing plates 104A and 104B so that the opening / closing can be performed from the central portion, and the front end of one opening / closing plate 104A is an end surface portion 105 bent in a substantially U-shape. On the other hand, the tip end of the other opening / closing plate 104B is an end face portion 106 having a bent piece that projects upward, and when the lid is in the closed state, the other end face portion 105 has the other end. End face portion 106 of
Mutual relationships are selected so that

The fixed plates 102, 103 are used to take in air during container transportation and to exhaust air from the inside.
In this embodiment, through holes 107 and 108 sealed by a filter are provided in each of the embodiments. Similarly, the pair of opening / closing plates 104A and 104B are also provided with a plurality of through holes 109, 110, and 111 which are sealed with a filter.

In this example, a drain port 113 is provided at the bottom center side of the right side face portion in this example, and a pair of scum discharge ports 114, 115 are provided near the water surface. The drainage port 113 is a drainage port having a relatively large diameter in consideration of being used as a live fish outlet. The scum discharge ports 114 and 115 purify water in the water tank 101 (including seawater in addition to fresh water; the same applies hereinafter) to remove fine particulate suspended matter (scum) floating on the water surface during transportation. It is for discharging at the timing.

FIG. 2 is a cross-sectional view taken along the line II ′ of FIG. 1, and FIG. 3 is a cross-sectional view taken along the line II-II ′ of FIG. To explain, as shown in FIG. 2, a predetermined amount of water 11 is stored in the water tank 101.
7 is housed, and an electromagnetic water treatment device 30 is installed at a predetermined position on the bottom of the water tank, that is, on the left center bottom in the example of FIG. The electromagnetic water treatment device 30 has a function of sterilizing and purifying water by giving an electric field and a magnetic field, and at the same time, has a function of releasing a large amount of oxygen into the water to increase the amount of dissolved oxygen. To do.

In the water tank 101, a wave damping lid (inner lid) 120 is provided so as to be openable and closable at a position closer to the water surface. Therefore, the inner lid 120 also includes the pair of opening / closing plates 12
The hinges 130 and 131, which are a plurality of opening and closing attachment means, are attached and fixed to the inner wall of the water tank 101, and the opening and closing plates 120 and 120B are fixed to the hinges 130 and 131.

The inner lid 120 is designed so that it can be opened from the center, and in this embodiment, one opening / closing plate 1 is used.
An end surface portion 1 of which the tip end portion of 20A is bent in a substantially U shape
22, the other end of the opening / closing plate 120B has an end face 1 having a bent piece protruding upward.
It is assumed that the mutual relationship is selected so that when the lid is closed, one end surface portion 122 abuts the other end surface portion 123 when the lid is closed.

Here, in order to allow the inner lid 120 to be opened and closed without being obstructed by the opening and closing lid 104 which is the outer lid,
As shown in FIG. 3, the width of the inner lid 120 is selected to be narrower than the opening / closing lid 104 and located inside the pair of fixing plates 102 and 103. Further, by selecting such a width, it is possible to smoothly perform the vertical circulation (circulation) of water.

If the inner lid 120 is submerged in water in this way, even if the transport container 100 shakes during transport, the inner lid 1
Since the movement of water is suppressed by 20, the entire water tank is hydrostatic. That is, the inner lid 120 can realize a water control effect that can cope with not only sudden shaking (short-period shaking) but also long-period shaking.

In order to prevent air from being taken in during the transportation of the container and to prevent the scum rising to the water surface from being blocked, the pair of opening / closing plates 120A and 120B also have filters 125-1.
A plurality of rectangular through holes 128-1 sealed with 27
30 is provided (see FIG. 3).

On the inner wall of the water tank 101 and the lower surface of the inner lid 120, a cushioning material 1 such as expanded polystyrene or sponge is provided.
No. 35 is attached without any gap so that even if live fish hits the inner wall, it will not be damaged. In particular, since young eels and the like often hide in the bottom and four corners of the aquarium 101, they are less likely to be damaged even when sudden shaking occurs. Therefore, the electromagnetic water treatment device 30 placed in the water
Covering the area with a net made of nylon or the like will be even more effective as a measure for protecting live fish. Transport container 10
0 is transported by being loaded on a freight carrier or a transportation truck.

In the present invention, the electromagnetic water treatment device 30 is arranged in the water tank 101, and the inner lid 120 for damping the wave motion is attached, so that the live water is kept in the water tank 101 for a long distance and a long time ( (Weeks to months)
Even if carried over, without dying live fish,
It can be transported to the target farm. The reason why such long-distance and long-term transportation is realized is that the live fish is kept from being excessively stressed and the water in the aquarium can be always kept clean.

Next, the above-mentioned electromagnetic water treatment device will be described. The water treatment device 30 releases a large amount of oxygen-based active species produced by electrolyzing the absorbed dirty water into water, and sterilizes bacteria in the water by the active species. At the same time, both the electric field generating means and the magnetic field generating means are provided in the water treatment device 30, and the ion species electrolyzed by the electric field generating means are oriented in the direction of the electric field and attracted to the electrode side of the electric field. The water component around the organic matter contained in the wastewater is rotated at high speed.

When the water molecule is rotated at a high speed, friction occurs between the organic molecule and the water component, and the friction heat causes the organic molecule to be wet-burned. When the organic molecule burns, the organic molecule is decomposed into carbon dioxide gas, ammonia gas, etc., and the organic molecule diverges and disappears. This treatment reduces the organic molecules in the water.

Further, + ions are attracted to the surface of the dirty clumps that have passed through the magnetic field (the clumps (colloids) which are fine particles such as sludge and flakes).
Although it is in the state of an ion sheath, the ion sheath adsorbed on the surface of the contaminated mass by the Lorentz force against + ions by the electric field and the magnetic field is peeled off. When the amount of + ions is stripped off and the amount of + ions is reduced, the binding force between the colloidal particles is strengthened and the colloidal particles are recombined and float in water. A water treatment device 3 is used for the floating colloidal particles.
Since a large number of ultrafine granular bubbles (bubbles) generated within 0 adhere to the surface thereof, they eventually float to the water surface due to the buoyancy of the bubbles. Water is purified by collecting the suspended matter (scum).

That is, in the water treatment device 30 according to the present invention, the sterilization function by the electrolysis of water, the combustion function of the organic matter by the electric field and the magnetic field, and the floating action of the waste material simultaneously achieve the purification including the sterilization in water. it can. The water temperature is preferably provided with a water temperature adjusting means so as to maintain a predetermined temperature (for example, about 22 to 23 ° C.).

The sterilization process will be described with reference to FIG.
It As shown in FIG. 4A, a predetermined voltage is applied between the anode 12 and the cathode 14.
Voltage (DC voltage) is applied to generate an electric field between the electrodes.
It In other words, create an electric field. Contains germs between electrodes 12 and 14.
Pour dirty water (water to be purified). Electrodes 12, 14
Water is electrolyzed when water is passed between them. By electrolysis
The main water-splitting substance generated at the anode is O.₂, H₂O ₂, O
H, O₃, O, and other oxygen-based active species. Oxygen activity
All species, to varying degrees, exhibit bactericidal activity.

The main water-splitting substance produced on the cathode side is H
₂ , H, etc., and all of these hydrogen-based active species exert a reducing effect. When these active species float in water, the oxygen-based active species encounter bacteria, which oxidize and kill them. When it does not encounter bacteria, it rapidly decomposes to produce water and oxygen. When the hydrogen-based active species encounters an oxidant, it reduces the oxidant to produce water or hydrogen.

While the active species generated by electrolysis, which are released into water in this way, have a bactericidal effect and a reducing effect, the derived chemical substances are all water, oxygen and hydrogen. It can be said that this is a completely different sterilization system from other sterilizers.

Since a large amount of oxygen generated by electrolysis is released into water, the amount of dissolved oxygen in water increases, and as a result, aerobic bacteria grow, thereby returning to an environment where aquatic organisms can live. be able to.

The sterilization system can also have a double structure as shown in FIG. 4B. In this case, if the anode 18 and the cathode 16 are reversed before and after in the water flow direction, active species (ionic species) generated directly on the upstream side and having no direct effect on water purification are generated on the downstream side reverse polarity electrode. Active hydrogenation can be carried out using hydrogen ions, and active hydroxylation can be carried out using hydroxide ions. Further, since a large amount of oxygen-based active species and oxygen generated by this electrode pair installed on the downstream side can also be supplied to water, the amount of dissolved oxygen in water can be further increased.

Next, the burning of organic substances and the floating of colloidal particles will be described. Some of the water molecules are ionized, but most of them are not ionized and remain in the state of H ₂ O molecules. Water molecules have a large electric dipole moment and can be forcibly oriented in the electric field direction by an electric field. It is known as an elect-rheological effect that the electric field is concentrated around an organic substance that is dissolved in water, and water molecules around the organic substance tend to be strongly oriented in the electric field direction.

Further, the dipole of free water in which organic molecules do not exist resonates at around 20 GHz, but the structured water molecules around the organic matter have a very low resonance frequency around 200 MHz, which is extremely low. When a high-frequency electromagnetic field having a resonance frequency or higher is applied, the water molecules can be rotated at a higher speed, and the high-speed rotation heats the water molecules. When the water molecules around the organic matter rotate at high speed, the organic molecule can be intensively heated by the frictional heat between the organic molecule and the water molecule.

Here, if the water flow is a high-speed water flow, even if a uniform magnetic field (DC magnetic field) is used instead of the high-frequency magnetic field because the water molecules flow down at a high speed, the water molecules can be similarly rotated at a high speed. You can Structurally, it is easier to apply a DC magnetic field to the water flow.

Therefore, as shown in FIG. 5, magnetic field generating means such as a magnet 20 is provided for the electrodes 12 and 14. High-speed water flow (20-30m /
By moving sec) at a right angle to the bundle of magnetic fields (magnetic field), high-speed rotation can be given to the water molecules of the high-speed water flow passing through the magnetic field. For example, since the flow velocity in free water is about 100 GHz at 100 m / sec,
It becomes about 20 GHz in high-speed water flow.

The structure of the hydrated water molecule near the interface with the organic molecule is destroyed by applying this high-speed rotation, and heat is generated around the organic molecule in an extremely short time of about several microseconds. Wake up. The heat transfer rate by water molecules around organic molecules is relatively slow, which is a few msec for one water molecule, so it becomes extremely high temperature in an instant, and due to this high temperature and oxygen activated by electrolysis, , Wet combustion (pyrolysis) of organic molecules,
The organic molecules are decomposed and emitted into carbon dioxide gas, ammonia gas, etc., and disappeared (burned).

When the ionized ions pass through the magnetic field, Lorentz force acts on the ions,
The + ion sheath that is attracted to the surface of colloidal particles such as sludge and clots of sludge is peeled off by Lorentz force. As a result, the binding force between the colloidal particles is strengthened, and eventually the colloidal particles are recombined with each other to aggregate. This aggregation occurs while floating in water.

When ultra-fine air bubbles are adsorbed to the recombined (aggregated) colloidal particle mass (SS) in water, the colloidal particle mass is buoyant by a large amount of bubbles, and the inner lid 1
It floats on the water surface through the outside of 20 (see FIG. 3) and through the through holes 128 to 130. The suspended material (scum) of the flocculated colloidal particles is sludge. By removing the sludge, the water is purified. Therefore, the scum is discharged by opening the discharge ports 114 and 115 at an appropriate timing during conveyance. Water is replenished in the water tank 101 by the amount discharged.

If the electrode pair has a two-stage structure and the magnetic field generating means is arranged in the electrode pair of the first stage and only the electric field generating means is provided in the second stage (downstream side), the electric field and the magnetic field of the first stage are generated. The electrolysis of water molecules is promoted, and a large amount of hydrogen and active species of water can be generated. At the same time, since a large amount of active oxygen species (oxygen-based active species) is present in the anode of the electrode pair, it is possible to create an environment for easily burning organic molecules. In addition to this, a large amount of oxygen-based active species can be released into water by releasing the water flow passing through the second electrode pair into water.

Ultra-fine-grained bubbles can be generated by adopting the following means. As shown in FIG. 6, when the rod-shaped fins 22 that are intake pipes are placed in a high-speed water flow (swirl flow), the flow velocity near the tips of the fins 22 becomes faster than the flow velocity near the center thereof. The pressure near the tip of the fin is negative. As a result, if the fin 22 is provided with the air guide port 24, the air is sucked and flows into the high-speed water stream. This mixes the high velocity water stream with the air to create bubbles.

The bubbles collide with another fin 22 provided on the downstream side thereof, so that the bubbles are crushed and the size of the bubbles is sheared to 1/2 or less than the original size each time they collide. Therefore, if a plurality of fins are arranged in the circumferential direction and the fins are arranged in two or more stages with respect to the water flow, the water flow swirling in the circumferential direction repeatedly collides with these fins 22 and flows down repeatedly. . For example, 10 fins
By arranging them individually, approximately 1/1000 equally divided bubbles can be obtained. Therefore, the bubbles become ultra-fine particles. When air bubbles with extremely small particle size are released into water, they will float in water, so they also have a good affinity (bonding force) with colloid particle aggregates that are also suspended in water. It will float in a state of being adsorbed in large quantities on the surface of. When such bubbles are adsorbed, the aggregate buoyancy causes the aggregate of colloidal particles to eventually float above the water surface.
The suspended matter of this colloidal particle mass is collected (exhaust ports 114, 1
By discharging (15), the water is purified and returns to the same transparency as when water was injected.

An embodiment of an electromagnetic water treatment apparatus which realizes such water treatment will be described in detail with reference to FIG. FIG. 7 is a conceptual diagram of the electromagnetic water treatment device 30.
The electromagnetic water treatment device 30 is a submersible pump 30 as shown.
A and a water purifying unit 30B provided above the A. A pipe 32 made of metal or resin is connected to the suction port 31a of the submersible pump 30A, a float 34 is attached to the tip of the pipe 32, and a water absorption part 36 with a filter is provided in a part of the float 34. The water immediately below the water surface (including sewage; hereinafter referred to as sewage) is absorbed by the water absorption part 3
It is led to submersible pump 30A via 6.

From the outlet 31b of the submersible pump 30A, sewage is guided to the water purifying section 30B with a predetermined flow velocity. An air intake means is arranged above the water purifier 30B. As shown in the figure, a metal or resin pipe 48,
The float 49 having an air intake port provided on its upper end surface constitutes an air intake means. Float 49
Is for the air intake to project above the water surface.

Air is sucked from the float 49, and the sewage that has passed through the submersible pump 30A passes through the water purifying section 30B as shown by the broken line a to generate oxygen-based active species that contribute to sterilization. After the organic molecule contained in the wastewater is burned and the colloidal particles are treated with an ion sheath, the organic molecules are discharged into the water through the discharge port 38a. In this way, the oxygen-based active species released into the water sterilize the bacteria living in the water around the apparatus, and the organic molecule is incinerated by wet combustion inside the water treatment unit 30B.

FIG. 8 is a sectional view of this water purification device 30. The water purification apparatus 30 has a tubular case 38 made of a metal or resin that is resistant to corrosion, and the water purification unit 30B provided inside the tubular case 38 is a sewage water guided by an underwater pump 30A. Pressure unit 40A for accelerating the flow velocity
And the electrolysis of the accelerated sewage and a process of wet-burning organic matter molecules and the like, the pressurizing unit 4
It is composed of an electromagnetic section 40B located at the lower part of 0A, and a bubble shearing section 40C which shears the bubbles generated by mixing the taken-in air and sewage into ultrafine particles.

Explaining in order, first, the pressurizing section 40A has an upper inner cylinder 42 and an upper outer cylinder 44, both of which are made of a metal resistant to corrosion, and the upper outer cylinder 44 has a relatively large sewage intake port. 44a is provided, and the sewage pumped up by the submersible pump 30A by the connecting pipe 45 is used as the upper inner cylinder
Water is poured into the water flow space 52 between the upper casing 2 and the upper outer cylinder 44.

An air intake port 4 is provided at the top of the upper inner cylinder 42.
6 is provided and the air is taken in from above the water surface as shown in FIG. 7 by using the pipe 48 connected thereto. The taken-in air is discharged into the water flow space 52 through a plurality of intake ports 50 provided in the circumferential direction at the substantially middle portion of the upper inner cylinder 42, and the taking-in of this air will be described later. .

At a predetermined position on the outer circumference of the upper inner cylinder 42, a semicircular moon shape is formed as shown in FIG.
The pressure vanes 54a and 54b for generating and pressurizing a pair of swirling flows having substantially the same diameter as the inner diameter are attached and fixed on the same circumference with a predetermined inclination angle. By mounting the pair of blades 54a and 54b in a state of being inclined by a predetermined angle, the interval between the facing opening surfaces of the pressure blades 54a and 54b is narrowed. Thus, the pair of pressure vanes 54a, 5
By slantingly mounting 4b and narrowing the facing opening surface, dirty water passing through the facing opening surface is accelerated while swirling and discharged into the downstream water flow space 52.

Incidentally, the flow velocity of the sewage that has passed through the pressurizing portion 40A is accelerated by a ratio corresponding to the ratio of the opening area of the intake port 44a to the area of the opposed opening surface formed by the pair of pressurizing blades 54a and 54b. Therefore, by appropriately selecting the area ratio, sewage becomes a high-speed water flow and flows into the downstream side.

At the predetermined position below the upper inner cylinder 42, two upper and lower
A plurality of rod-shaped fins 55, 5 having a predetermined length over the steps
6 are attached and fixed radially toward the water flow space 52. These rod-shaped fins 55, 56 are provided for sucking the air in the upper inner cylinder 42 and discharging it into the water flow space 52.

As shown in FIG. 10, when four rod-shaped fins 55 on the upper stage are fixed to the upper inner cylinder 42, rod-shaped fins 56 are arranged below the rod-shaped fins 55. , It is attached and fixed by shifting by 45 °. Further, the rod-shaped fins 55, 56 are provided with air guide ports 55a, 56a at their central portions, respectively.

As described above, the air sent into the water flow space 52 from the intake port 50 is mixed with the dirty water in the water flow space 52 to generate bubbles. This bubble is up and down 2
By colliding with the rod-shaped fins 55, 56 of the step, the bubbles are gradually reduced because they are crushed.

The flow velocity on the tip side of the air guide ports 55a, 56a in the rod-shaped fins 55, 56 is as follows.
Since the flow velocity of the bubbles flowing on the outer peripheral surface of 56 is slower, the pressure in the vicinity of the tips of the rod-shaped fins 55, 56 becomes negative, and the air in the air guide ports 55a, 56a becomes a water flow space 52.
Be drawn in. This causes more bubbles.
As described above, the rod-shaped fins 55 and 56 are provided to reduce the bubbles and to multiply the bubbles.

The outer cylinder disposed outside the upper inner cylinder 42 is divided into two in this embodiment, and the upper outer cylinder 44 has a length up to the vicinity of the intake port 50. Therefore, the middle outer cylinder 58 connected to the upper outer cylinder 44 has a length selected so as to cover the upper inner cylinder 42 to which the pair of rod-shaped fins 55 and 56 are attached.

The upper inner cylinder 42 and the middle outer cylinder 58 constitute an electromagnetic section 40B. The electromagnetic section 40B includes an electric field generating means 60 and a magnetic field generating means 62. The electric field generating means 60 performs electrolysis and orientation of water molecules,
The magnetic field generating means 62 is provided for wet-burning organic molecules and forcibly stripping the ion sheath of colloidal particles such as sludge, flakes, and sludge.

First, the electric field generating means 60 is constituted by the cylindrical electrode pair constituted by the upper inner cylinder 42 and the middle outer cylinder 58, and an electric field (electric field) is formed in the water flow space 52.
Magnetic field generating means 62 is provided on the outer peripheral surface of the middle outer cylinder 58. In this embodiment, a magnet (such as a permanent magnet or an electromagnet) is used as the magnetic field generating means. Therefore, in this example, as shown in FIG. 11, a predetermined interval, for example, about 45 °
Eight rod-shaped permanent magnets 62 as magnetic field generating means at intervals of
Is attached. For the magnetic field, a bar-shaped magnet is used so that the side of the central outer cylinder 58 has an N pole and the outside has an S pole. A metal band 64 for fixing the magnet is attached to the outer side of the rod-shaped magnet 62, and the metal band 64 also functions as an electrode for the middle outer cylinder 58.

Next, the bubble shearing section 40C will be described. The bubble shearing portion 40C is also made of a metal material such as stainless steel which is not easily corroded.
6, the lower inner cylinder 64 has disc-shaped upper and lower closing plates 68, 70 made of metal or resin, and has a disc-like shape on a part of its peripheral surface (upper side of the center). A flange 72 is attached. Although the upper and lower closing plates 68, 70 are made of metal, the flange 72 may be made of metal or resin.

As shown in FIG. 12, the upper blocking plate 68 is selected to have an outer diameter substantially the same as the tip diameters of the rod-shaped fins 55, 56, while the lower blocking plate 70 has the outer diameter of the lower outer cylinder 66 ( Actually, the outer diameter is almost the same as the diameter up to the flange). In the location of the lower blocking plate 70 facing the water flow space 52, there are a plurality of drain holes 70a having a long diameter or a circular shape.
Is provided.

On the other hand, inside the lower outer cylinder 66, in this example, fins for shearing air bubbles (shearing fins) 74 are provided in two stages.
76 are radially provided with a predetermined interval. FIG. 9 shows the relationship between the shear fins 74 and 76 and the flange 72 and the upper closing plate 68.

As shown in FIG. 12, the shearing fin 74 on the upstream side is provided.
Are radially attached at intervals of approximately 90 °, the shear fins 76 on the downstream side are radially attached while being rotated by approximately 45 °. The length thereof is almost the length facing the flange 72, but this is merely an example.

The plurality of inner cylinders and outer cylinders described above are used as electrodes. Therefore, each of the plurality of inner cylinders 42, 64 and outer cylinders 44, 58 described above is made of a metal material such as a stainless material, which is resistant to corrosion, as described above.

As shown in FIG. 13, the plurality of inner cylinders and outer cylinders form a double electrode pair. Therefore, for example, when the upper inner cylinder 42 is the negative electrode, the middle outer cylinder 58 is the positive electrode via the band 64,
Further, the lower inner cylinder 64 on the downstream side is electrically connected by the lower closing plate 70 to serve as a + electrode. The lower outer cylinder 66 is used as a negative electrode. Further, in order to apply a predetermined voltage to each electrode to form a predetermined electric field, the electrodes 79a to 79d are welded to the corresponding positions as shown in the figure. With this, the electric field generating means 60 is constituted by a pair of cylindrical double electrodes. A current of about 1 to 3 amperes is applied to the pair of electrodes at a voltage of about 10 to 30 V, though it depends on the inner diameter and the electrode structure.

The pressurizing section 40A, the electromagnetic section 40B and the bubble shearing section 40C configured as described above are housed in the cylindrical case 38 as shown in FIG. However, the tubular case 38 is not long enough to cover the entire submersible pump 30A, but long enough to cover only the head of the submersible pump 30A. Furthermore, this tubular case 38
Is formed as a trumpet-shaped opening, and the opening is used as the discharge port 38a. As a result, even when the submersible pump 30A is installed on the bottom of the water as shown in FIG.
A proper distance is maintained between the discharge port 38a and the water bottom.

As shown in FIG. 13, the connection flanges 44b, 5b are provided on the outer cylinders 44, 58, 66, respectively.
8a, 58b, 66a, 66b are provided, and these are connected via ring-shaped packing materials 80a-80c. As a result, the three outer cylinders 44, 58 and 66 are connected to each other in a watertight manner while electrically insulating each other.

Now, the water treatment in the electromagnetic water treatment apparatus 30 thus constructed will be described below. As shown in FIG. 3 or 14, the electromagnetic water treatment device 30 is installed with the submersible pump 30A on the lower side. The length of the pipe 32 is selected according to the water depth, the float 34 floats on the water surface, and the water absorbing portion 36 is located immediately below the water surface.

A float 49 is also provided in the pipe 48 for taking in air to introduce air into the water treatment section 30B. A power cord is also provided in the pipe 48 to supply power to the submersible pump 30A and the like.

When the submersible pump 30A is driven, water is poured into the water treatment section 30B from the submersible pump 30A. Although the flow velocity (flow rate) of the sewage discharged from the submersible pump 30A is determined by the capacity of the submersible pump 30A, the submersible pump 30A of 1 kW was used in this embodiment. The flow rate at that time is 100 l / min.

The water taken into the water flow space 52 of the pressurizing section 40A is pushed out to the downstream side of the water flow space 52 while being pressurized by the rod-shaped fins 55 and 56. Since the rod-shaped fins 55, 56 are inclined and fixed with respect to the upper inner cylinder 42, water passes through the rod-shaped fins 55, 56 to form a swirling flow, and the water flows down at a high speed. In this example, the flow velocity is about 20 to 30 m / sec.

The water that has flowed down is mixed with the air supplied from the intake port 50 to generate bubbles. The bubbles reach the electromagnetic portion 40B while swirling on the peripheral surface of the upper inner cylinder 42. In the electromagnetic section 40B, air is further mixed by the air supplied from the rod-shaped fins 55 and 56 to generate bubbles.
Since an electric field is applied to the electromagnetic portion 40B, water molecules, particularly water molecules existing around the organic molecule, are strongly oriented in the direction of the electric field, and the water molecules are electrolyzed to the anode side. Oxygen-based active species as described above are generated in the middle outer cylinder 58. This oxygen-based active species is also generated by the pair of electrodes 64 and 66 on the downstream side,
A large amount of oxygen-based active species is released into the water through the outlet 38a.

Among the oxygen-based active species, ozone and hydrogen dioxide have a strong bactericidal action, and thus sterilize bacteria in water. Therefore, if the oxygen-based active species are continuously released into the water by continuously operating for a certain period of time, eventually the area within the predetermined range from the place where the electromagnetic water treatment device 30 is installed will be sterilized. You can

Further, since a magnetic field (0.4T (Tesla) level in this example) is generated in the electromagnetic section 40B, when a water flow passes through it, water molecules around the organic matter molecules are rotated at a high speed, The high-speed rotation causes friction between organic molecules and water molecules, and high heat is generated by the friction. The frictional heat causes the organic molecules to be wet-burned and disappear.

Since a large amount of oxygen generated by applying electrolysis and applying a magnetic field is released into water, the amount of dissolved oxygen in the water increases, and aerobic bacteria in the water proliferate accordingly. Becomes more active. As the amount of dissolved oxygen increases, aquatic organisms can become habitat, and the purifying action by this can be expected.

Further, the ion sheath is destroyed by the water flow passing through the magnetic field. This is because a part of the colloidal particles is stripped off by the Lorentz force applied to the + ion sheath on the surface. As a result, the colloidal particles are released into water in a state where the binding force between them is strengthened.

The water flow reaching the bubble shearing section 40C is prevented from being swirled by the upper blocking plate 68 and the disc 72, and the swirling flow is prevented from being concentrated on the lower inner cylinder 64 side, and the lower outer cylinder 66 side is suppressed. Scatter into. And the shear fins 74, 7
As a result of the collision of the bubbles, which is a swirling flow, with 6, the bubbles are finely sheared. As a result, the bubbles become ultra-fine bubbles.
Its diameter is approximately 10 microns.

The ultrafine air bubbles are discharged into water as shown in FIG. The ultrafine air bubbles are adsorbed to the surface of the sludge particles (sediment such as defecation) in the air bubble shearing portion 40C and water. The colloidal particles to which the ultrafine air bubbles are attached float in water, and eventually rise to the water surface by the buoyancy of the ultrafine air bubbles. Floating matter (scum) floating on the water surface is collected. By collecting the suspended matter, when the water is contaminated in combination with the above-described wet combustion of the organic molecule, it is purified and the transparency in the water is restored.

In this way, the water in the water tank is sterilized and purified. In addition, increased dissolved oxygen and aerobic bacteria improve the habitat for live fish. This is done in water without generating ozone on the ground, so there is no need to consider ozone odor. Further, since the high-speed swirling flow can be generated only by the submersible pump 30A and the pressurizing unit 40A, the electromagnetic water treatment apparatus 30 has no rotating mechanism at all, and therefore the configuration of the apparatus itself is extremely simple.

Further, since only the submersible pump 30A and the electromagnetic section 40B are used as the power source, the electromagnetic water treatment apparatus 30 has a number of epoch-making which cannot be obtained conventionally, such as extremely low maintenance cost. It can be said that this is the most suitable water treatment device.
