[Industrial applications]

 The present invention relates to a device for purifying water quality by supplying and diffusing activated air to pond water, lake water, river water, and the like.

[0002]

[Prior Art]

Conventionally, air is supplied into water for the purpose of removing various volatile substances in water and oxidative decomposition of organic substances.Blowers and submerged agitators are used to blow and diffuse air. Was there. In order to improve the efficiency of water purification, it is necessary to widely diffuse the air into the water, and it is desirable to stir the water at the same time as the air is supplied, but in order to stir the whole pond, a large amount of power is required. I needed it. Also, in order to activate air and supply it into water, it has been known that air pressurized by a blower is passed through a magnetic field to activate O ₂ in the air and then supplied into water. Air was heated by the heat of compression to 70 ° C. or higher, the magnetic force was attenuated or the magnetic field was destroyed, and sufficient activated air could not be obtained.

[Problems to be solved by the device]

 The present invention eliminates the drawbacks of the conventional agitator for pond water and the like, significantly reduces the initial cost and running cost, is easy to maintain and manage, and efficiently purifies and agitates pond water and the like. It is intended to provide a device.

[0004]

[Means for Solving the Problems]

 According to the present invention, an air supply line is connected to a negative pressure part of a submersible agitator with a rotary impeller, and a plurality of hollow disk-shaped permanent magnets magnetized in the axial direction are coaxially contacted with the same pole in the air supply line. This is a purification device for pond water or the like characterized by interposing a built-in magnetic activation device, and is characterized in that a fine powder additive supply port is opened in the air supply line.

[0005]

[Action]

When the submersible stirrer with a rotating impeller is driven by being immersed in water, the water flow is diffused throughout the pond, and at the same time, the vacuum energy generated in the stirrer sucks air from the negative pressure section into the air supply line. Although it is efficiently dispersed as fine bubbles in water, it passes through many different magnetic fields that exist continuously while passing through the magnetic activation device in the air supply line, and O ₂ is activated, the molecular cluster becomes smaller and becomes finer, and it becomes easier to mix with water. Also, when the feed port for the fine powder additives such as bait, algaecide, and water activator is opened in the air supply line, these fine powder additives are sucked together with the air and diffused into the water. In this way, the vacuum energy generated in the submerged agitator with a rotating impeller is used to supply air and fine powder additives into the water without any additional power, and the air is not heated but magnetically activated. It does not affect the equipment, and the fine powder additive does not deteriorate due to heat.

【Example】

An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes pond water, and a submersible agitator 2 with a rotary impeller is held at a certain depth in water by a pedestal 3. As the submerged agitator 2 with a rotary impeller, an impeller 7 provided with an auxiliary impeller 6 is attached to the tip of a drive shaft 5 that rotates in a shaft casing 4 by a drive device (not shown), as shown in FIG. The rotation of the impeller 7 in the impeller casing 8 diffuses the water flow in the entire pond, and at the same time, a negative pressure portion is generated in the shaft casing 4. An air supply pipe 12 having an air intake container 11 having an upper lid 10 provided with an air intake port 9 as shown in FIG. 3 attached to an end thereof is connected to the negative pressure portion, and a submersible agitator with a rotary impeller is connected. The air is sucked from the air intake container 11 by the vacuum energy generated by the drive of 2, but the magnetic activation device 13 is arranged in the middle of the air supply pipe 12, and the air passing through the air supply pipe 12 passes through. It is like this. As shown in FIG. 4, the magnetic activation device 13 includes a non-magnetic material such that a plurality of hollow disk-shaped permanent magnets magnetized in the axial direction are coaxially contacted with the same pole in the outer casing 14. The outer cylinder ferrite magnet 16 incorporated with the reversal collar 15 interposed therebetween and the inner cylinder ferrite magnet 17 made of a similar hollow disk-shaped permanent magnet inside the outer cylinder ferrite magnet 16 are provided. The nozzle plate 19 was attached with the mounting nuts 20, and the outer cylinder ferrite magnet 16 and the inner cylinder ferrite magnet 17 were held between the nozzle plates 19, and the air passing through these magnets existed continuously. By repeatedly passing through the magnetic field, O ₂ in the air is activated, and the branched clusters become smaller and finer and easily mixed with water. Therefore, when the impeller 7 is driven and the water flow is diffused throughout the pond water, the air energy is generated and the air is sucked from the air intake container 11, passes through the air supply pipe 12, and passes through the magnetic activation device 13. During the operation, the air is activated, then becomes fine and is efficiently diffused in the pond water 1. In addition, a fine powder additive supply port 21 such as bait, algaecide, and neutralizer can be opened at an appropriate position in the air intake container 11 or the air supply pipe 12 so that the fine powder additive supply port 21 can be diffused into the pond water together with the inhaled air. it can.

[Effect of the device]

As described above, according to the present invention, the extremely beneficial effects listed below are produced. O ₂ in the atmosphere can be efficiently diffused to the whole by the vacuum energy of the stirrer without requiring any other power. By activating O ₂ in the atmosphere, the purification treatment efficiency can be increased. The vacuum energy of the stirrer can efficiently disperse the fine additives to be supplied into the pond water. Compared to the conventional air supply method using a blower, the initial cost and running cost can be reduced significantly, and at the same time, the installation area is almost unnecessary on the ground.
