2. Description of the Related Art In order to keep seafood for a long time in a stationary water tank on land or in a water tank on a live fish transport vehicle, the temperature of seawater in the water tank should be kept constant and the dissolved oxygen concentration in water should be kept constant. It is said that the minimum of three elements is to keep it and to keep the seawater in the aquarium constantly moving so that it has a water flow. Therefore, there is no problem if a fresh water stream can always be supplied to the aquarium, but in the case of a stationary tank or a tank on a live fish transport vehicle that cannot supply a fresh water stream, the same seawater must be circulated, and It was considered difficult to make the best use of it for a long time. However, in recent years, in the process of circulating the same seawater, natural oxygen is replenished or oxygen is replenished using an oxygen cylinder, and the water temperature is also kept constant by using an artificial cooling device. Can survive for a long time. In addition, a filter layer is placed in the circulation route of seawater, and a carbon dioxide gas discharged from the fish and shellfish living in the water tank is neutralized in this filter layer, and a filter tank using a filter medium that adsorbs ammonia nitrogen is used. It was provided.

In the above-mentioned known live fish tank, the impurities such as carbon dioxide gas and ammonia nitrogen generated in the live fish tank are filtered by a filter tank. For that reason, a large surface area of the filter material constituting the filtration tank is required, and as a result, a large filtration tank is required.
Therefore, in the stationary water tank on land, there is a problem that the live fish tank and the filtration tank are configured as separate water tanks, and piping equipment is required between them. In addition, in the water tank on the live fish transport vehicle, the size of the filter tank is large, so that there is a problem that the live fish tank becomes smaller by the amount of the limited vehicle volume.

In view of the above-mentioned problems of the known live fish tank, the present invention has a construction in which the size of the filtration tank can be made small even in the stationary water tank, and the live fish tank and the filtration tank are integrated into an installation site. The purpose is to provide low cost by eliminating the need for piping work etc. in the live fish tank. Also, even in the live fish tank on the live fish transport vehicle, the filtration tank is made small so that the live fish is in a limited volume. The purpose is to make the tank larger.

[0005]

Therefore, in the live fish tank of the present invention, the live fish tank, the impurity separation tank, the temperature adjusting tank, and the filtration tank are constituted by a water tank having an integrated structure, and water is circulated between them. It has a pump, and the circulation of water by this circulation pump is arranged in the order of a live fish tank, an impurity separation tank, a temperature adjustment tank, and a filtration tank.
Is equipped with an automatic oxygen dissolving device .

[0006]

In the live fish tank according to the present invention, water is circulated from the live fish tank to the impurity separation tank, then to the temperature adjusting tank, and then to the filter tank, and the water is circulated from the filter tank to the live fish tank. Impurities are separated in the impurity separation tank before they reach the filtration tank, and this impurity separation tank is equipped with an automatic oxygen dissolving device.
Therefore, the impurities are efficiently separated in the impurity separation tank, and the water in which the impurities are separated in the impurity separation tank is sent to the filtration tank.
