【００１９】
又、魚を生かしたままたくわえておくところである生簀では魚の泳ぐ方向に水が流れていてその流れに乗って泳ぐ習性を有した魚である例えばまぐろ等の魚は生簀内の水が一定方向に流れていないと長く生きておくことができないものである。ところで生簀に相当する水槽１であるこの水槽１の他の実施例では濾過槽２の上部室部１０の水を水槽１に落下させる落下用管１１の下方先端流出口部２２は折曲部２３を介して折曲すると共に下方先端流出口部２２より流出する水で水槽１内の水が一定方向に循環流動するように指向して取付けたので水槽１内の水は魚の泳ぐ方向に流れてまぐろ等の魚の生存に大いに寄与するものであり、且つ又落下用管１１内を落下して下方先端流出口部２２より流出する水は水槽１内の水中に開口している下方先端流出口部２２より流出するので水の落下音を減少して静かな生簀を得ることが出来るものである。
【００２０】
以上のようにこの発明は水槽の中での魚自体の排泄物や餌の残り等が腐敗しての猛毒のアンモニアの発生を抑えて魚を長期に亘り元気に生存させることができるようにすると共に海水魚等の生きた魚を水槽に入れて一般の家庭に於いては観賞用として楽しみ又は魚料理店に於いては店頭、客室等に設置した水槽に料理に使用する生きた魚を入れて営業上の広告用とすることができるもので取扱いが好適で使用上便利なもであり、構造が簡単で安価に提供出来ると共に取扱いが容易で、更に簡便に製作できるものであり、且つ大量生産に適する等幾多の産業的作用効果を奏するものである。

Those mounted directed to the aquarium water 15 in the water tank 1 and.
[001 2 ]
Therefore, fish are bred and raised in the aquarium 1, and the water in the aquarium 1 is raised to the lower chamber 9 of the filtration tank 2 provided in the upper part of the aquarium 1 through the pumping pipe 4, and the lower chamber The water is raised to 9 through the filter medium layer 8 formed of porous particles such as coral sand, and is further raised to the upper chamber 10. The water is circulated by dropping into the water, and the circulating water can change the circulation speed and the circulating water capacity depending on the pumping capacity of the attached pump 3.
[001 3 ]
In addition, the water in the aquarium 1 may cause troubles such as the excrement of fish itself and the rest of the food rot and become highly toxic ammonia, which makes it impossible to survive for a long time. The water in the water tank 1 containing ammonia is allowed to survive in the filter medium layer 8 in the process of being raised from the lower chamber 9 to the upper chamber 10 through the filter medium layer 8 formed of porous particles such as coral sand. It changes into good quality water containing the necessary oxygen, which means that the filter medium layer 8 formed of porous particles such as coral sand eliminates highly toxic ammonia and changes the water into oxygen containing water. It is the one that generates bacteria.
[001 4 ]
The high-quality water raised to the upper chamber 10 is dropped into the water tank 1 through a drop pipe 11 attached to the filtration tank 2, and this drop pipe 11 is filtered at the upper inlet port 12. The lower end outlet 14 is positioned below the upper edge 13 of the tank 2 and attached to the water tank surface 15 in the tank 1 and filtered. The water falling from the tank 2 to the water tank 1 is water that is in contact with the outside air and mixed with oxygen when flowing over the upper inlet 12 of the dropping pipe 11 or when flowing out from the lower outlet 14 of the dropping pipe 11. It is dropped into the aquarium 1 to supply necessary water by the survival of the fish and contribute to the breeding of the fish.
[001 5 ]
Further, the water passing through the filter medium layer 8 is forced to flow upward from below the filter medium layer 8 via the pumping pump 3, and extinguishes the highly toxic ammonia according to the size of the water tank 1 and the type of fish. It is possible to reliably obtain the water necessary for the survival of the fish by installing the pump 3 that can obtain a flow of water suitable for extinguishing the highly toxic ammonia through the filter material layer 8 generating the filtering bacteria. It can be done.
[001 6 ]
Further, the lower suction port 5 of the pumping pipe 4 opened below the water tank 1 is connected to a filtration flat body 17 provided on the bottom surface 16 of the water tank 1, and further, porous particles such as coral sand are provided above the filtration flat body 17. By providing the bottom filter material layer 18 formed in the above, the water filtration operation of raising the water to the filter tank 2 through the pumping pipe 4 through the bottom filter medium layer 18 is performed, and the filter medium layer 8 attached to the filter tank 2 is soiled. It reduces the time required for cleaning and the like for a long period of time, making it very convenient to use.

Further, the pumping pipe 4 having the upper discharge port 6 opened below the filtration tank 2 is provided with a bent pumping pipe portion 19 positioned above the upper end edge 13 of the filtering tank 2 in the middle of the pumping pipe 4 and bent pumping. Since the pipe 19 is provided with the backflow prevention air hole 21 directed to the filtration tank water surface portion 20, when the pump 3 is stopped due to a power failure or the like, the siphon action of the pumping tube 4 does not work and the filtration tank water surface portion 20 With a slight descent, air flows into the bent pumping pipe portion 19 from the backflow prevention air hole 21, and for this purpose, the inside of the filtration tank 2 passes through the pumping pipe 4 from the upper discharge port 6 opened below the filtration tank 2. Water can flow safely back into the lower suction port 5 opened below the water tank 1, overflowing the water from the water tank 1, and can be used safely without causing troubles such as flooding around the water tank 1. .

Further, when the water flows through the pumping pipe 4 with the operation of the pumping pump 3, the state where water blows out from the backflow prevention air hole 21 toward the filtration tank water surface portion 20 continues. Oxygen is supplied to the water in the filtration tank 2 by blowing.

In addition, in the ginger, where the fish is kept alive, water flows in the direction of the fish's swimming, and the fish that has the habit of swimming on that flow, such as tuna fish, the water in the ginger is in a certain direction If it doesn't flow, it can't live long. By the way, in another embodiment of this water tank 1 which is a water tank 1 corresponding to a ginger, the lower end outlet part 22 of the dropping pipe 11 for dropping the water in the upper chamber part 10 of the filtration tank 2 to the water tank 1 is a bent part 23. The water in the aquarium 1 is attached so that the water in the aquarium 1 circulates and flows in a certain direction with the water flowing out from the lower end outlet portion 22 and the water in the aquarium 1 flows in the direction of fish swimming. The lower tip outflow portion that greatly contributes to the survival of fish such as tuna and that flows out of the lower tip outflow portion 22 after dropping in the dropping tube 11 is opened in the water in the aquarium 1. Since the water flows out of the water 22, the sound of falling water can be reduced and a quiet ginger can be obtained.

As described above, the present invention enables the fish to survive vigorously for a long period of time by suppressing the generation of highly toxic ammonia caused by the decay of fish excrement and food residue in the aquarium. At the same time, put live fish such as saltwater fish in the aquarium and enjoy it as an ornamental in the general household, or in the fish restaurant, put the live fish used for cooking in the aquarium installed in the storefront, guest room, etc. It can be used for commercial advertising, is easy to handle and convenient to use, has a simple structure and can be provided at low cost, is easy to handle, and can be manufactured more easily, and can be manufactured in large quantities It has many industrial effects such as being suitable for production.
