The present invention relates to a pressure water tank for aquatic organisms that allows for transportation of fertilized eggs, hatching of these fertilized eggs, and cultivation of plants such as algae.

Conventionally, pressure tanks for aquatic organisms that have been put into practical use either perform air ration, in which air is blown into the water from an air pump, or use the air from the air pump as an air lift, to maintain dissolved oxygen in the water. Aeration is carried out above. Furthermore, oxygen is supplied into the water from an oxygen cylinder via a pressure regulating valve by air ration. However, all of these were conducted at atmospheric pressure.

In conventional aquariums for rearing aquatic organisms, the inside of the aquarium is at atmospheric pressure, and the amount of dissolved oxygen in the water at atmospheric pressure is limited by the water temperature, specific gravity, etc., for example, as shown in Figure 3. As shown in a, the oxygen partial pressure of the air in a normal aquarium is 0.21 atm, and the amount of dissolved oxygen is limited to about 5 c.c./c.

In addition, even if oxygen cylinders are used, high pressure oxygen is dangerous and poses security problems, and on remote islands,
There is a problem in that oxygen cylinders are difficult to obtain in remote areas.

題を有している。 However, in the above method, when feeding in a high-pressure aquarium, it is necessary to reduce the pressure each time to bring it to atmospheric pressure before feeding, which causes the organisms to be pressurized and depressurized repeatedly each time, causing a large amount of damage to the organisms. It has the problem of having an impact. In addition, circulating filtration of the rearing water is difficult due to the high pressure, so the rearing water is contaminated with the excrement of the rearing organisms, resulting in the problem that the number of housed organisms must be kept as low as possible.

In the present invention, for example, as shown in FIG.
The air compressor 2 is driven to pressurize the water in the pressure water tank 1 and the gas in contact with the water, and as the pressure increases, the oxygen partial pressure in the gas rises, thereby increasing the amount of dissolved oxygen in the pressure water tank 2. On the other hand, when feeding, when the on-off valve 14 is opened, the pressure water tank 1
The high-pressure air inside enters the feeding tank 15 as air bubbles, gradually increasing the internal pressure inside the feeding tank 15.At this time, the air bubbles stir the breeding water and food to mix the food evenly, and eventually the feeding tank 15 is filled with air. When the internal pressure in the tank 15 becomes equal to the pressure in the pressure water tank 1, the breeding water mixed with food falls to the water surface of the pressure water tank 1, and the food is eaten by the living organisms. In addition, since the pressure inside the filtration device 6 is equal to the pressure inside the pressure water tank 1 due to the pressure equalization pipe 25, the circulating water is circulated through the water pump 4, the filtration device 6, and the aeration device 24, and filters the excrement of the cultivated organisms to make it suitable for use. We try to maintain good water quality.

昇する。 To explain the operation of the present invention having the above configuration, the air compressor 2 is driven and the pressure water tank 1 is
The amount of dissolved oxygen in the pressure water tank 2 is increased by pressurizing the water and the gas in contact with the water, and increasing the oxygen partial pressure in the gas as the pressure increases. For example, as shown in Figure 3b, the gauge pressure is 3Kg/cm 2
The oxygen partial pressure of pressurized air is 0.84 atm when pressurized to
This corresponds to air containing four times as much oxygen as at atmospheric pressure, and gas dissolves in water that comes into contact with this pressurized air, resulting in a fourfold increase in the amount of dissolved oxygen in the water. Further, when the pressure is increased to 3 Kg/cm 2 with pure oxygen, the oxygen partial pressure in the gas phase becomes 4.0 atm, and the amount of dissolved oxygen in water in contact with this gas phase increases to 95 c.c./cm 2 .

うにしてもよい。 Furthermore, by driving the air pump 3, the high pressure air above the pressure water tank 1 is blown into the pressure water tank 1 from the air ration device 11, and further by driving the water pump 4, the water in the pressure water tank 1 is blown into the pressure water tank 1. The oxygen is ejected from 24a, 24b, and 24c into high-pressure air to promote the dissolution of oxygen. Alternatively, the type and amount of living organisms may be input, and the air compressor 2 may be automatically controlled by a microcomputer to maintain the pressure water tank 1 at a desired atmospheric pressure.

Close. At the time of feeding, when the on-off valve 14 is opened, high-pressure air in the pressure water tank 1 mixes into the feeding tank 15 as bubbles, gradually increasing the internal pressure in the feeding tank 15. At this time, the air bubbles stir the breeding water and food to evenly mix the food.
When the internal pressure in the feeding tank 15 eventually becomes equal to the pressure in the pressure water tank 1, the breeding water mixed with food falls to the water surface of the pressure water tank 1, and the food is eaten by the living organisms. If some food remains due to the degree of predation, the on-off valve 14 is closed to stop feeding. In addition, the type and amount of the bred organism may be inputted, and the opening/closing valve 14 may be automatically controlled by a microcomputer to automatically feed the animal.

てしまうためである。 Next, the action of the filtration device 6 will be explained.
Normally, the on-off valve 23 and the on-off valve 26 are open, and the inside of the filtration device 6 is connected to the pressure water tank 1 by the pressure equalizing pipe 25.
The circulating water is circulated through the water pump 4, the filtration device 6, and the aeration device 24 to filter the excreta of the cultivated organisms and maintain appropriate water quality. When replacing the filter material in the filtration device 6, the circulating water is introduced into the aeration devices 24a, 24b, and 24c by switching the three-way valve 21a, and after closing the on-off valve 23 and the on-off valve 26, the pressure-resistant Open the lid 22 and replace the filter material. When the replacement of the filter medium is completed, the on-off valve 26 is first opened to equalize the pressure inside the filtration device 6 with the air pressure inside the pressure water tank 1 through the pressure equalization pipe 25, and then the on-off valve 23 is opened. This means that if you suddenly open the on-off valve 23,
The filtration device 6 is filtered by the high pressure air in the pressure water tank 1.
This is because the filtration material inside is agitated and the filtration function is deteriorated.

率よく浄化できるものである。 In the filtration device 6, ammonia nitrogen, which is biological excrement in the rearing water, can be converted into harmless nitrate nitrogen by bacteria living inside the filter material, and the remaining feed can also be filtered in the same way. , the culture water can be maintained well for a long period of time even under high pressure. At this time, bacteria in the filter medium,
Like aquatic organisms, they consume oxygen, but because they are exposed to high pressure air, the partial pressure of oxygen becomes higher than normal.
The purification ability of bacteria increases and purification can be performed more efficiently than under atmospheric pressure.

As explained above, according to the present invention, it is possible to increase the amount of dissolved oxygen in the aquarium, as well as to feed under high pressure and filter the breeding water, so that the aquarium environment can accommodate aquatic organisms at a high density. This allows for long-term breeding or transportation to remote locations, and it is also possible to significantly reduce breeding or transportation costs.

の搬入が可能となる。 Furthermore, by mixing chemicals into the feed, it can be administered orally to aquatic organisms, making it possible to treat diseases under high pressure. Furthermore, depending on the diameter of the piping, it is possible to transport fertilized eggs, young fish, and small fish while keeping the aquarium under high pressure.
さらに、水棲生物の排泄物のアンモニア態窒素
