[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater axial bubble generating device with a magnet for generating fine bubbles that are widely used for activating and purifying water in live fish tanks, fish ponds, hydroponics, etc. is there.

[0002]

2. Description of the Related Art Conventionally, as this type of underwater bubble generator or underwater aerator, it has been proposed to atomize bubbles by an impeller or a propeller blade that rotates integrally with an underwater motor. In addition, a mixing device including an inner cylinder and an outer cylinder, which is jetted into water from a lower end opening of the inner cylinder, is also proposed.

[0003]

In the former of the above-mentioned conventional techniques, when the bubbles are generated in the water to supply oxygen, the bubbles are very large and immediately float up, so that the Since the residence time is very short, there is a problem that the efficiency of dissolution in water is not good. Further, in the latter, the bubbles are extremely fine, and since the bubbles stay in the liquid for a long time, the dissolution of oxygen is extremely good, but regarding the effect of activation and sterilization of the internal organic matter, There is a problem that is not addressed at all. The present invention has been made in view of the above problems,
Its main purpose is to install several permanent magnet rotating wheels on top of the stirring and mixing impeller on the rotating shaft of the inner cylinder, which causes chemical changes of anions and cations in the invading seawater. In other words, the present invention provides an underwater axial bubble generating device with a magnet for generating hydrogen and oxygen to enhance the activity and sterilization of organic matter in water.

[0004]

In order to achieve the above-mentioned object, the present invention has a motor (1) at the upper part and a space between it and an inner cylinder (5) on the outer circumference of a rotating shaft (2) at the lower part. Provide the outer cylinder (6) with a strainer. Several stirring and mixing impellers (3) (3) ...
Wear ... These several stirring and mixing impellers (3) (3)
A number of permanent magnet rotating wheels (4) with a certain spacing on top of
The intended purpose is achieved by adopting the configuration equipped with (4).

[0005]

Next, the usage of the present invention will be explained. When the motor (1) is driven, the stirring and mixing impeller (3) and the permanent magnet rotary wheel (4) of the rotary shaft (2) rotate together, and the strainer-equipped external unit. Seawater that has entered from the cylinder (6) enters from the water suction hole (7) in the upper part of the inner cylinder (5) and is ionized by the chemical change by the permanent magnet rotating wheel (4), so that air, seawater, etc. Inner cylinder (5) with vigorous stirring and mixing with liquid
The gas is ejected as fine air bubbles into the liquid on the side by the diffusion wheel (10) from the lower end opening. Then, the ionized liquid jetted into the liquid imparts activity and sterilization property, prolongs the residence time in the liquid, and dissolves in every corner of each water tank, thereby exerting an action of good efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, referring to the drawings, an embodiment of the present invention will be described. A motor (1) located at the upper part is equipped with a vertical rotary shaft (2) at the lower part. Agitating and mixing impellers (3) (3), which generate a few bubbles, are fixed to the rotary shaft (2) at predetermined intervals. With an inner cylinder (5) with a predetermined gap on the outer circumference of the stirring and mixing impellers (3) (3), and a strainer with a strainer formed on the outer circumference with a predetermined gap on the outer circumference of the inner cylinder (5) The outer cylinder (6) is installed upright. Next, the agitating and mixing impellers (3) and (3) of the rotating shaft (1) are attached with permanent magnet rotating wheels (4) of various stages of several stages on the upper part thereof at a predetermined interval or connected. is there. The inner cylinder (5) is provided with a water suction hole (7) for the seawater or the like infiltrated from the outer cylinder (6) with at least one strainer at the top. Further, an air supply pipe (8) for sucking air from the outside air is installed on the upper part of the inner cylinder (5). At the lowermost end of the rotating shaft (2), a diffusion wheel (10) for ejecting fine air bubbles (11) (11) .. The code (12) is
A base plate for supporting the motor (1) is shown, and (13) is a float for a float, which is installed as necessary.
Reference numeral (14) indicates a pedestal mounted with a gap below the diffusion wheel (10). (15) shows the water surface of the aquaculture tank, live fish tank, and the like.

EFFECTS OF THE INVENTION Since the present invention has the above-mentioned structure, it enables the generation of fine bubbles, which cannot be achieved by the conventional bubble generating device, and achieves a chemical change of ionization in a fluid such as seawater. As a result, hydrogen and oxygen are generated, and there is an excellent effect that the activity of the fluid and the bactericidal action are improved. Then, several stirring and mixing impellers are attached to the rotating shafts inside the outer cylinder and the inner cylinder with strainers, and several permanent magnet rotating wheels are attached to the upper part of the impellers. In addition to the effect of being strongly sucked and generating fine air bubbles, the fluid is ionized by the chemical change by the permanent magnet rotating wheel, the activity is improved and the sterilizing effect is sufficiently achieved, and the permanent magnet rotating wheel also has an impeller. As described above, there is an effect that it functions as agitating and mixing, and assists suction and mixing. Further, the several permanent magnet rotating wheels axially attached to the rotating shaft also have the effect of constantly contacting seawater or the like while rotating and increasing ionization by electrolysis.
