Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is applied to a fish breeding aquarium used in general households.

The present invention is particularly suitable for use as an aquarium for raising ornamental fish such as tropical fish and saltwater fish.

〔Overview〕

The present invention relates to a multi-stage breeding aquarium comprising a first aquarium for breeding fish and a second aquarium including means for receiving the overflow and filtering it again to supply it to the first aquarium. By stacking on the second tank, pumping the water at the outlet of the purifying means to the first tank, and dropping the overflow water of the first tank to the inlet of the purifying means, the purification capacity is improved and clean water is maintained for a long time. It enables the maintenance of fish, and enables the breeding of delicate types of fish.

[Conventional technology]

Conventionally, fish that have been improved for appreciation, such as goldfish, are resistant to water contamination in the aquarium due to excretions from the fish and food residues, etc., so aquariums installed at the entrances of housing complexes, etc. It is easily raised in Japan.

Recently, breeding of marine fish and tropical fish has been required in such a small space.

Since such fish are sensitive to water pollution and oxygen concentration, the water quality must be adequately controlled, and the number of fish stored in one tank must be extremely smaller than that of goldfish.

For this reason, two water tanks, one for raising fish and one for filtering and removing pollutants, are prepared, and the water in these tanks is circulated so that the water in these two tanks has the same environment. It has been attempted to keep the number of fish stored in the rearing tank at a higher density than in the case of the single tank type.

[Problems to be Solved by the Invention]

The amount of water constantly stored in the second water tank, the filtration tank, requires a certain amount in order to make its filtering capacity effective. However, it is difficult to increase the size of the aquarium in a small room and to determine the installation location of the second aquarium. In the case of using a water tank, the water tank of a fixed shape has a water supply pipe connected to a water pump inside the water tank, which complicates the water supply means for circulating water between the two tanks.

Also, the size and shape of the second water tank must be determined each time according to the installation position. Therefore, the conventional two-tank type not only increases the manufacturing cost but also is not manufactured in a unified manner, which causes inconvenience in the operation of flushing and cleaning. Further, a water temperature adjusting device for tropical fish and the like is often provided in the first aquarium, which hinders viewing. Especially in the breeding of marine fish, since there is a strong demand for viewing as if it were an aquarium tank, the presence of the water supply pipe and the water temperature adjusting device in the first tank hinders viewing.

The present invention solves these problems, improves purification ability, and can easily perform management suitable for raising delicate fish, and can maintain and maintain an environment such as an aquarium in a small space. The purpose is to provide an aquarium.

[Means for solving the problem]

The present invention is directed to a first aquarium in which fish are bred, a second aquarium provided separately from the first aquarium and having a purifying means for purifying water, the first aquarium and the second aquarium. In a multi-stage breeding aquarium provided with a circulation means for circulating water between the first water tank and the second water tank, the circulation means is an outlet of the purification means. Means for pumping the above water to the first water tank, an overflow port provided at a predetermined height of the first water tank, and the water at this overflow port is dropped to the inlet of the purifying means of the second water tank. It is characterized by including a headrace channel.

The second water tank is divided into a plurality of compartments along a water flow path, one of the compartments is a precipitation tank, the other one of the compartments is a filtration tank, and the second water tank of the first water tank is It is desirable that the weight is supported by the outer wall or the partition wall of the second water tank.

[Action]

The upper opening of the second water tank is larger than the bottom of the first water tank, and the bottom of the first water tank is fitted in a part of the upper opening of the second water tank to supply filtered water. Are placed in other parts of the upper opening that are not covered. For this reason, the overall required floor area can be reduced, and since the first water tank is fixedly mounted on the second water tank, it is not affected by vibration such as an earthquake or impact such as touching the first water tank. The aquarium does not roll over.

Since the upper part of the second water tank is wide open, it is easy to clean and replace the internal filter. Further, since the bottom of the first water tank acts as a lid for the upper opening, the water accumulated in this can be prevented from evaporating. A water pump and a heater or thermostat that adjusts the water temperature in the upper opening that is not covered by this bottom.
An air pump etc. can be arranged.

Since the water supply pipe is outside, connection with the pump is easy and maintenance is not required.

It is aesthetically desirable to arrange so that the part that is not covered by the bottom is the back of the first aquarium. Then, the upper part of the water pump or heater that cannot be submerged will be hidden behind the first tank. Making the back of the first aquarium opaque hides the tools behind it. Also, the back surface can be transparent.

Further, the first water tank is stacked on the second water tank, the circulation means pumps the water at the outlet of the purifying means into the first water tank, and the water from the overflow port provided at a predetermined height of the first water tank. By dropping to the inlet of the purification means of the second aquarium, it is possible to improve the purification capacity and maintain clean water for a long time,
The frequency of cleaning can be reduced.
