った。(Problems to be solved by the device) However, in these methods, various gases harmful to fish such as ammonia gas, methane gas, and sulfide gas are easily accumulated in water due to decay of fish excrement and residual feed sediment. , The water in the aquaculture pond and various tanks could not be purified sufficiently.
そのため、魚の皮膚に病気が発生したり、また、養魚場
においては稚魚を充分に成長させることができない等の
弊害が生じていた。As a result, the skin of the fish is ill, and the fry cannot be sufficiently grown in the fish farm.
その後、こうした問題点を解決すべく、特開昭51−2535

を混入する曝気装置が提供されるようになった。After that, in order to solve these problems, JP-A-51-2535
No. 9, JP-A-53-18008, and JP-A-60-193594, an aeration device for impinging oxygen into water by colliding a water stream with a fixed object has been provided. .
しかしながら、こうした曝気装置では、流れ込む水が、
固定物に一度衝突するだけなので、水や気泡は十分に微
細化されず、水中に溶け込む酸素の量は十分ではなかっ
た。However, in such an aeration device, the flowing water is
Since it only collides with the fixed object once, water and bubbles were not sufficiently atomized, and the amount of oxygen dissolved in water was not sufficient.
また、その他の構造のものとして、特開昭52−81948号

る。Further, as another structure, an aeration device as disclosed in JP-A-52-81948 is also provided. This aeration device has a first rotary blade that causes a swirl flow and an axial flow in the liquid, and a second rotary blade that rotates in the opposite direction, and is arranged so as to float in the liquid. The mesh blades of the second rotary blade cause a swirling flow and an axial flow to collide with the flowing liquid and finely shear the bubbles mixed in the liquid.

ある。Therefore, in view of the above existing problems, the present invention does not transmit mechanical vibration noise that causes stress to fish into water, and ammonia gas generated in water, methane gas,
Providing an underwater dissolved oxygen supplier that eliminates various gases that are harmful to fish, such as sulfide gas, and efficiently supplies oxygen in water to increase the amount of dissolved oxygen in water and purify water in an extremely short time. It was devised as an issue.
