よって損傷されない。When the blade plate 11 is rotated by the driving of the underwater motor 1, the water between the upper and lower horizontal partition plates 9 and 10 and the blade plate 11 moves toward the outer circumference. Therefore, the outside of the stepped shaft 2 between the upper and lower horizontal partition plates becomes a negative pressure, and air flows from the air chamber 5 through the communication hole 2C and into the stirring section 12, and the blade plate 1
The air is stirred by the rotation of 1, and the air is divided into fine particles and mixed with water. Therefore, the gas-liquid contact area increases, gas-liquid contact is sufficiently performed, and a large amount of oxygen can be dissolved in the water. Furthermore, the water mixed with air collides with the rod of the strainer, and the air is further divided into fine particles, which are mixed into the water and promote the dissolution of the air. The fish in the fishpond are prevented from entering the stirring section by the strainer, so they are not damaged by the rotating blades.

とができる。(Effects of the Invention) The above-mentioned throat (the present invention) connects a stepped shaft having a large-diameter flange at the upper part to the rotating shaft of a vertically oriented underwater motor, Drill a communication hole,
An air chamber is provided between the submersible motor and the flange, an air communication pipe is connected to the air chamber, and an upper horizontal bulkhead plate is provided on the outer periphery of the lower part of the flange, and the lower horizontal bulkhead plate is connected to the above-mentioned stage at a distance. Since a plurality of vanes are provided between the upper horizontal bulkhead plate and the lower horizontal bulkhead plate, water between the upper and lower bulkhead plates and the vane plate moves toward the outer circumference by rotation of the vane plate. Therefore, the outside of the stepped shaft between the upper and lower partition plates becomes negative pressure, and air flows out from the air communication pipe/air chamber through the communication hole in the flange, is agitated by the rotation of the blade plate, and the air is fragmented. Since the particles become fine particles and mix with water, the gas-liquid contact area increases, gas-liquid contact is sufficiently performed, and a large amount of oxygen can be dissolved in the water.
