ツクである。 In the accompanying drawings, an underwater oxygen generator 10 according to the present invention accommodates a predetermined amount of catalyst, that is, manganese dioxide 12, which also functions as a settling weight, and a predetermined amount of sodium percarbonate 14 as an oxygen generating raw material. A water intake port 18 is provided at the top opening of the container body 16.
The lid member 20 with the opening is removably attached, for example, by screwing or the like. A fume part 22 made of, for example, a synthetic sintered material is formed around the water intake port 18 of the lid member 20. On the other hand, a valve body guide pipe 24 extending into the container body 16 is disposed in the water intake port 18 of the lid member 20, and a plurality of water inlets 26 are opened at predetermined locations on the side wall of the guide pipe 24.
Valve seats 28 are formed directly above these water inlets 26. Further, inside the guide tube 24, a spherical valve 34 is connected to the float member 30 via an arm 32.
Insert and place. In the accompanying drawings, reference numerals 36 and 38 are a hook used when recovering the underwater oxygen generator 10, and a drainage pot for draining water from the container body after oxygen generation is completed.

若干量併せて投入すれば、後述する溶液反応を確
実にかつ円滑に行わせることができ好適である。 When using the underwater oxygen generator 10 according to the present invention configured as described above, the lid member 20 is removed and a predetermined amount of manganese dioxide 12 (catalyst) crushed into irregular shapes is spread inside the container body 16. After that, a predetermined amount of sodium percarbonate 14 as an oxygen generating raw material is added and the lid member 20 is attached again. At this time, if a small amount of powdered manganese dioxide or solid manganese dioxide, which has a different disintegration time in water depending on polyvinyl alcohol, is also added, the solution reaction described below can be carried out reliably and smoothly. This is suitable.
次いで、この容器本体１６を養魚場などの水中

侵入を阻止する。 Next, when this container main body 16 is submerged in water at a fish farm or the like, water enters into the main body 16 through the intake port 18 (guide pipe 24) and the inlet port 26, and the float member 30 gradually floats to the surface. When water reaches a predetermined amount, the spherical valve 34 seats on the valve seat 28 to prevent water from entering.
水の侵入に伴つて容器本体１６内では、触媒１

おける溶存酸素を増加させる（第２図参照）。 As water enters the container body 16, the catalyst 1
Decomposition reaction between water and sodium percarbonate 14 in the presence of 2 [2Na 2 CO 3・3H 2 O → 2 (Na 2・H 2 O) +
H 2 O + 1.5O 2 ] occurs, and the oxygen gas generated by this reaction stays in the space of the container body 16 and then blows out as bubbles through the fumarole 22, increasing dissolved oxygen in the water (second (see figure).
なお、この場合、単位時間当たりの酸素発生量

を長時間発生させる必要があるときは過炭酸ナト
リウムを適宜増量すれば良いが、この場合でも本
体１６内に侵入する水と過炭酸ナトリウムとの重
量比を４：１程度以内に設定するのが好ましい。 In this case, the amount of oxygen generated per unit time is proportional to the sum of the surface areas of the catalyst (manganese dioxide), so if the catalyst is formed into fine particles, it is possible to generate a large amount of oxygen in a short time. , for example, 1 to 2 mm in order to prevent catalyst diffusion (water contamination) and facilitate recovery at the end of oxygen generation.
It is preferable to form it into a granular shape. In addition, if it is necessary to generate oxygen for a long time, the amount of sodium percarbonate may be increased appropriately, but even in this case, the weight ratio of water entering the main body 16 and sodium percarbonate should be set within about 4:1. It is preferable to do so.
なお、溶液反応による酸素の発生が終了した後
は、掛止フツク３６を介して容器本体１６を懸吊
し、排出コツク３８を操作して内部の侵入水を排
出して次の使用に備えて適宜保管すればよい。 After the generation of oxygen by the solution reaction is completed, the container main body 16 is suspended via the hook 36, and the water that has entered inside is discharged by operating the drain pot 38, in preparation for the next use. Just store it as appropriate.
