<p>PURPOSE: To incorporate high-concn. oxygen water into lifted water and to efficiently increase the dissolved oxygen quantity of the water in a wide water basin by installing an intermittent air lifting device into the central part of a large-sized cylindrical body and installing a means for releasing the high-concn. oxygen water to the inner side of this large-sized cylindrical body. CONSTITUTION: Floats 2 are fixed to the outer side of the top end of the composite lifting cylindrical body 1 formed by bundling plural cylinders 1a, 1b and an air chamber 3 is fitted to the outer side at the bottom end. A weight 4 is connected to the bottom end. On the other hand, a cylinder 5 is loosely fitted to the outer side of the composite lifting cylinder 1 and the bottom end thereof is installed to a foundation 7 of a water base 6. Air is introduced from respective water flow holes 12 to 14 into a flow regulating cylinder 30 to form air bubble bullets 31 when the air quantity in the air chamber 3 increases and the air arrives the water flow hole 12 of an inside cylinder 11. These air bubble bullets 31 are thereafter divided and are simultaneously supplied into the respective lifting cylinders 1a, 1b where the air rubble bullets 18 are risen to rise the water in the respective lifting cylinders la, lb. At this time, the high-concn. oxygen water rises by entering the ascending water when this oxygen water is fed from a water feed hose 35. The water is then released in the form of the water mixture from the top end of the cylinder 5.</p> |
