Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is applied to fish breeding tanks used in general households.

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

〔overview〕

The present invention provides a multi-stage breeding aquarium comprising a first aquarium for breeding fish and a second aquarium including means for receiving overflow water, filtering it, and supplying it again to the first aquarium. By stacking the water on top of the second water tank, pumping the water from the outlet of the purification means into the first water tank, and letting the overflow of the first water tank fall into the inlet of the purification means, the purification ability is improved and the water is kept clean for a long time. It was designed so that it could be maintained and even delicate types of fish could be raised.

[Conventional technology]

In the past, fish that were improved for ornamental purposes such as goldfish,
They are resistant to contamination of the water in the aquarium by fish excrement and food residue, so they are easily kept in aquariums installed at the entrances of housing complexes.

Recently, there has been a growing demand for breeding marine fish and tropical fish in such small spaces.

These fish are sensitive to water pollution and oxygen concentration, so water quality must be carefully controlled, and the number of fish kept in one aquarium must be extremely small compared to goldfish.

For this purpose, two aquariums are prepared: a breeding tank for raising fish and a filtration tank for filtering and removing pollutants, and the water in these tanks is circulated so that the water in these two tanks is at the same level. By doing so, the number of fish housed in the breeding tank can be reduced compared to the case of a single tank type.
Efforts are being made to allow them to be kept at higher densities.

[Problem to be solved by the invention]

A certain amount of water is required to be constantly stored in the second water tank, ie, the filtration tank, in order to make its filtration ability effective. However, in a small room, it is difficult to increase the size of the aquarium and decide where to install the second aquarium. When using a regular water tank, a water supply pipe connected to a water pump is provided inside the tank, making the water supply means for circulating the two types of water complicated.

Further, the dimensions and shape of the second water tank must be determined each time depending on the installation location. For this reason, the conventional two-tank type is not only expensive to manufacture, but also not uniformly manufactured, which causes inconvenience in watering and cleaning operations. Furthermore, water temperature control devices for tropical fish and other fish are often installed in the first aquarium, which hinders viewing. Particularly when breeding marine fish, there is a strong desire to view them as if they were in an aquarium, so having the water supply pipe and water temperature control device in the first tank hinders viewing.

The present invention solves these problems by improving the purification ability and making it easier to manage delicate fishes.For example, it is possible to maintain and raise an aquarium-like environment in a small space. The purpose is to provide an aquarium.

[Means to solve the problem]

The present invention provides a first aquarium in which fish are raised, a second aquarium that is provided separately from the first aquarium and has a built-in purifying means for purifying water, and a second aquarium that is arranged between the first aquarium and the second aquarium. In the multi-stage breeding aquarium, the first aquarium is stacked on top of the second aquarium, and the circulation means is connected to the outlet of the purification means. pump means for pumping water into the first water tank, an overflow port provided at a predetermined height of the first water tank, and water from the overflow port falling into the population of the purification means in the second water tank. It is characterized by including a water supply channel.

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

[Effect]

The top opening of the second tank is larger than the bottom of the first tank;
The bottom of the first aquarium is fitted into a portion of the upper opening of the second aquarium, and a water pump or the like for supplying filtered water is located in the other uncovered portion of the upper opening. Therefore, the overall required floor space can be reduced, and since the first tank is fixedly placed on the second tank, it will not be affected by vibrations such as earthquakes or shocks such as touching the first tank. The tank does not tip over.

The upper part of the second water tank is wide open, making it easy to clean and replace the filter inside. Furthermore, since the bottom of the first water tank functions as a lid for the upper opening, evaporation of water accumulated therein can be prevented. A water pump, a heater or thermostat for adjusting water temperature, an air supply pump, etc. can be placed in the upper opening that is not covered by the bottom.

Since the water supply pipe is located outside, it is easy to connect to the pump and requires no maintenance.

It is aesthetically desirable to arrange it so that the part not covered by the bottom is the back of the first aquarium. That way, the upper parts of the water pump, heater, etc. that cannot be submerged will be hidden behind the first tank. If the back of the first aquarium is made opaque, the tools behind it will not be visible from the front. The back side can also be made transparent.

Furthermore, the first water tank is stacked on the second water tank, and the circulation means pumps the water from the outlet of the purification means into the first water tank, and the water is pumped from the overflow port provided at a predetermined height of the first water tank. By dropping the water into the inlet of the purification means of the second aquarium, the purification ability can be improved, clean water can be maintained for a long period of time, and the frequency of cleaning can be reduced.
