<p>PROBLEM TO BE SOLVED: To restrain oscillation when waves are generated to increase safety by surfacing an agitator with its horizontal position being held by floats having buoyancy slightly larger than that balancing with the load, holding down the exposed height above the surface of the water in a floating state to improve a view and also reducing the impact surface of waves and by oscillation restraining action of the floats. SOLUTION: In an aeration agitator, by switching a switching valve 3 to the ejector 4 side to operate a submersible pump 2, air-water mixed fluid in which bubbles are mixed is discharged into water from a diffuser 4D, and by switching the switching valve 3 is switched to the water spray pipe 5 side to operate the submersible pump 2, water is sprayed from an outlet 5B of the water spray pipe 5. To the aeration agitator, large-sized submersible floats 10, 10 into which split in the width direction through a connecting frame 7 and eight small-sized waterborne floats 11A, 11B, 11C, 11D, 11a, 11b, 11c, 11d are fitted.</p> |
