Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an ornamental aquarium for raising live seafood for hobby purposes;
The present invention relates to aquariums for live fish restaurants, sushi restaurants, etc. for the purpose of sale, or aquariums for holding live fish and shellfish for display purposes such as aquariums, and specifically relates to an attached circulating filtration type purification device.

[Prior art and its problems]

When raising live seafood in an aquarium, there are especially few microorganisms that oxidize ammonia in the water in the aquarium in its initial state.
There has been a major problem in that ammonia, a metabolite of live seafood, accumulates without being oxidized, causing the seafood to die within two to three weeks when the living conditions for live seafood are established.

For this reason, there are many aquariums equipped with circulation filtration purification devices on the market, but conventional circulation filtration purification devices are attached above the aquarium, and a pump device pumps up the water in the tank. The water is guided and sprinkled over a filtration layer such as a nylon filter that is inside the device, and as the water is filtered by the filtration layer, ammonia is biooxidized by the biota of microorganisms that have grown on the filtration layer and returned to the aquarium. In the past, only ammonia treatment and filth removal were carried out to maintain living conditions for live seafood, and the process was only carried out through cyclical purification.

However, if used over time, algae may grow in the aquarium and adhere to the inner surface of the glass, the bottom surface, etc., and the color of the water in the aquarium may increase due to an increase in organic matter, making the water cloudy, and the water may become cloudy for a short period of time. There were problems such as the need to change the water at regular intervals and the need to clean the aquarium each time.

[Purpose of the invention]

In view of the above-mentioned problems, the present invention has been developed as a result of many years of research.
This solution solves the above problems.The ammonia contained in the water in the aquarium in the initial state is removed and rendered harmless by the pre-filter catalyst treatment layer, and the growth of algae is prevented by bringing it into contact with ozone in the ozone contact tank. To provide a purification device that prevents the generation of organic substances, minimizes the number of water exchanges, requires almost no cleaning, and maintains good survival conditions for live seafood. It is.

[Structure of the invention]

The configuration of the present invention is that, in an aquarium equipped with a circulation filtration type purification device that forcibly circulates water in the aquarium for breeding live fish and shellfish using a pump device, water is filtered by a pre-filter provided in the circulation system of the circulation filtration type purification device. The filtered water flows into an ozone contact tank equipped with an exhaust ozone treatment tower above, and the ozone contact tank is equipped with an ozone diffuser connected to an ozone generator and a catalyst treatment tank nearby. The structure is such that water that has been ozonated in a contact tank flows into a catalyst treatment tank and is then returned to a water tank.

[Embodiments of the invention]

Hereinafter, the present invention will be explained based on drawings of embodiments.

The drawing is a schematic diagram illustrating an embodiment of the present invention.

The present invention is a circulating filtration type purification device i! that is attached to an aquarium A such as an aquarium for viewing live seafood, an aquarium for display, an aquarium for rearing, etc. Regarding l, in an aquarium A for keeping live seafood alive, which is equipped with a circulation filtration type purification device 1 that purifies the water in the aquarium A by forcibly circulating it with a pump device 2, the circulation system of the circulation filtration type purification device 1. The filtered water that has been filtered through a pre-filter 3 provided at The air section 7 is placed inside and a catalyst treatment tank 8 is provided nearby, and the water that has been ozone treated in the ozone contact tank 5 flows into the catalyst treatment tank 8 and then flows back to the water tank A.

That is, the present invention is a circulating filtration and purification device 1 attached to an aquarium A for live fish and shellfish, and although it is installed above the aquarium A in the drawing, the circulatory system can be maintained even if it is installed near the side or the like. It's okay if it's possible.

The circulation system is composed of a pump device 2, a front filter 3, an ozone contact tank 5, and a catalyst treatment tank 8.

The pump device 2 receives electric power from an external power source, and includes a motor 21 as a driving source, a pump 22 that operates in conjunction with the motor 21, and a water suction pipe 24 equipped with a water suction strainer 23 at the tip.
The water sprinkling pipe 25 is disposed above the front filter 3 provided in the circulation system, and a number of water sprinkling holes 26 are suitably bored therein so that water can be sprinkled onto the front filter 3. It is something that exists.

The front filter 3 is made by appropriately laminating water-permeable fibrous or porous nylon filters, etc., and is surrounded by a wall on the side so as to filter the entire amount of water to be sprinkled. 3 to remove ammonia, impurities, etc.

The water treated with the front filter 3 flows into the introduction part formed in the partition wall between the front filter 3 and the ozone contact tank 5, and is converted into ozone by the ozone diffuser 7 inside the ozone contact tank 5. The ozone diffuser 7 uses an air pump to pump ozone generated by an ozone generator 6 such as an ultraviolet lamp type connected to a connecting pipe 9 such as a tube together with air to form fine bubbles into the water. It is released as

Next, the ozone-treated water overflows above the partition wall between the ozone contact tank 5 and the catalyst treatment tank 8, and flows into the catalyst treatment tank 8, which has a layered structure through which water such as activated carbon can pass. , which allows water to flow through the catalyst treatment tank 8.

Furthermore, the water that has been subjected to the catalyst treatment in the catalyst treatment tank 8 is returned to the water tank A through a discharge pipe 10 that penetrates the bottom surface 11 of the circulation filtration type purification device 1 and is erected to form a circulation system for treated water. It is.

Unreacted exhaust ozone, which is harmful to the human body, is generated in the air above the ozone contact tank 5, and a wandering ozone treatment tower 4 is formed with a catalyst layer to detoxify the exhaust ozone.
Then, the ozone contact tank 5 is closed and the exhausted ozone is removed.

Immediately after water is poured into the water tank A, that is, with water in the initial state, the ozone purifier 1 of the present invention is placed above or to the side of the water tank A, and when the power is turned on, the pump 2 operates in conjunction with the motor 21.
