Oxygen supply apparatus for suppling an oxygen with fish farm or water tank

摘要

PURPOSE: An oxygen supply device for supplying oxygen in a fish farm or a water tank is provided to keep live fishes for a long time by floating an oxygen supply device on the water of a fish farm or a water tank, pumping water by applying a pressure of 2.5kg/cm 2 to be guided in a critical device, and discharging the water through a critical pipe by applying a speed of 250km/hour to generate and supply the oxygen in the water; and to reduce a unit cost of products by sucking air in the atmosphere. CONSTITUTION: The oxygen supply device for supplying oxygen in a fish farm or a water tank comprises a floating plate(2) to be floated on the water of a fish farm or a water tank(1); a pump(4) with a hood valve(3) for pumping water at one side of the floating plate; a hydraulic pipe(6) with a pressure gauge(5) for guiding the water as pumped; a critical device(7) with another pressure gauge; an oxygen generation device(9) for supplying oxygen; a critical pipe(10) for supplying the mixed water and oxygen into the water; a supporter(11) formed on the floating plate for supporting the critical pipe.
