<p>PURPOSE:To dissolve a large volume of oxygen in water over a wide range by providing an air chamber between a submersible motor and a collar part, connecting an air communicating pipe thereto, providing vane plates between 1st and 2nd partition plates and providing a water intake port between the 1st and 2nd partition plates of a stepped shaft. CONSTITUTION:The water between the 1st and 2nd partition plates 9 and 10 and the vane plates 11 moves in the outer circumferential direction and a negative pressure is generated on the outer side of the stepped shaft 2 between the 1st and 2nd partition plates 9 and 10 when the vane plates 11 are rotated by driving of the submersible motor 1. Then, the air passes a communicating hole 2c from the air chamber 5 and flows into a stirring part 12. The water is admitted from the water intake hole 13 and is stirred by the rotation of the vane plates 11, by which the air is finely segmented to form fine particles which are mixed with the water. The mixed water and air are released to the outer periphery and is powerfully stirred with the water. The air is further finely segmented to form the fine particles which intrude into the water. The water flow released outward by the inclination of the vane plates 11 is pushed downward and is thereafter risen by the buoyancy of the air, by which the air is incorporated in the form of the fine particles into the water over the wide volume.</p> |
