Description

  The present invention relates to indoor aquatic aquaculture, and more particularly, to a configuration of an aquaculture tank with less vibration and noise.

  In recent years, it has become difficult to capture marine organisms as resources due to problems such as marine pollution, fishing rights, and protection of the natural environment.

  Even when cultivated on the coast, the optimal temperature differs depending on the aquatic organisms to be cultivated, and the water collected from the sea may not be used as it is due to the recent increase in seawater temperature. Therefore, when collecting and using aquaculture water from the sea, it may be necessary to adjust the temperature in the aquaculture tank. And there is a temperature range suitable for aquaculture depending on the kind of aquatic organisms, and adjusting the temperature affects the success or failure of the aquaculture, so the temperature control of the aquarium is important.

  On the other hand, there are aquatic organisms that are sensitive to vibration and noise. Among aquatic organisms, for example, shellfish such as sea bream, when they vibrate, feed on them extremely badly, stop growing, and in some cases die. Therefore, in the aquaculture environment, the generation of vibration and noise must be suppressed as much as possible, and even if it occurs, it must not be transmitted to the aquarium where it is cultivated.

  However, when the aquaculture water is sent to the aquaculture tank, it is only necessary to use a flow-down method that uses the difference in altitude to flow the water. However, when a pump is used, noise and vibration are inevitably generated from the pump itself and the motor used therefor.

Patent Document 1 shows an example in which a filter and a cooling / heating device are installed in the upper part of an aquarium where aquatic organisms are bred, and water in the aquarium is circulated by a pump.
In this apparatus, the water in the water tank 1 is pumped to the filter 3 by the pump 2, the filtered water is dropped into the cooling / heating machine 4, and the temperature-controlled water is poured into the water tank from the drain outlet 7.
In this case, the pump 2 is fixed to a filter disposed on the water tank 1.
However, there is no description about vibration and noise.

Patent Document 2 is an invention relating to a hot water heater that prevents vibration and noise.
In the specification of the present invention, “a base support is erected on the base constituting the bottom surface of the housing, a cistern base is fixed to the upper part of the base support, and a mounting plate is further erected from the cistern base, A cistern fixing bracket is welded to the side of the cistern tank, and the fixing bracket and the mounting plate are screwed. The cistern tank is located above the cistern base, and an anti-vibration rubber is placed on the bottom of one side between the cistern tank and the cistern base. Equipped with a water tank tray whose other end is screwed to the mounting plate, and a cistern tank is provided on the water tank tray via a cushion material, so that only one side of the cistern tank and the water tank tray is screwed. In the other direction, vibrations and noise generated from the cistern tank can be further reduced because vibration is doubly absorbed by the anti-vibration rubber and cushioning material. And "structure, such as no vibration or noise is described.

Conventionally, as described above, in order to control the temperature of a water tank as described above, water using a warm water heating apparatus as shown in Patent Document 2 is heated, or refrigerant in an apparatus having a similar configuration is reversed. The water was cooled by flowing.
As mentioned above, certain marine organisms are very sensitive to sound and vibration, so it is necessary to control the temperature of the aquarium that generates as little vibration and noise as possible. However, the method disclosed in Patent Document 2 is a large scale, and it is still difficult to completely prevent vibration and noise.

  In addition, although the device described in Patent Document 2 uses anti-vibration rubber and cushioning materials, the motor and pump of the pump unit are large sources of vibration and noise. In many cases, the use of elastic materials could not be sufficiently prevented, which was a problem for farmers.

  Therefore, in the system of the present invention for cultivating aquatic organisms, the difference between the altitudes of the aquarium positions is used while considering from the viewpoint of not generating vibration and noise as much as possible or not transmitting them to the breeding aquarium. It is possible to use a pump that does not use a pump that is a source of vibration and noise. Of course, it is preferable if it can be adopted.

  However, it is good if the water can flow into the aquaculture tank using the flow-down method, but in many cases, the water in the tank cannot be moved without using a pump. In addition, when directly heating and cooling the aquaculture water in the aquaculture tank, especially in the case of cooling, a compressor and a pump are often installed in the vicinity, and at that time it is difficult to prevent vibration and noise from being transmitted. In that case, it is necessary to keep the pump and the aquarium as far as possible so that no sound or vibration is transmitted between them.

Rather than directly heating and cooling the water in the breeding aquarium, a separate temperature adjustment tank is provided to adjust the temperature of the aquaculture water.
The method for adjusting the temperature is as follows.
Heat or cold air generated by the heat source device is transferred to the heat medium using a heat medium heat exchanger, and the heat medium is passed through the water heat exchanger for aquaculture to transfer heat or cold air to the aquaculture water.

Further, an aquaculture water heat exchanger disposed in the temperature control water tank and a heat medium circulation pump for circulating the heat medium in the heat medium heat exchanger are provided.
Thereby, the temperature of the aquaculture water is controlled to a temperature suitable for the aquatic organism to be cultivated.

  The aquaculture water controlled to an appropriate temperature is sent to a breeding aquarium by a water pump through aquaculture water supply pipes, where aquatic organisms are bred.

  The heat source device can be realized in the case of an air-conditioning room having an air conditioner or a cold / hot storage. And it can make it easy to prevent that a vibration and noise are transmitted to a breeding water tank by providing the water storage room which installs the said temperature control water tank, and the breeding room which installs the said breeding water tank in another room.

  Conventionally, in order to control the temperature of the water tank, the water is warmed by using a hot water heating apparatus as shown in Patent Document 2, or the water is cooled by flowing the refrigerant of an apparatus having a similar configuration in the reverse direction. It was. In that case, it is absolutely necessary to use a pump. Then, the aquatic organisms in the aquaculture tank are affected by vibrations / noise caused by the pump and the pulsating flow generated in the coolant sent out by the pump and the aquaculture water. Conventionally, it has been difficult to prevent this, but by implementing the present invention, transmission of vibration / noise and pulsating flow is cut off in the temperature-adjusted water tank. If the present invention is applied, it is not necessary to use a vibration-proof rubber or a cushion material.

  An embodiment of the water tank apparatus of the present invention will be described with reference to FIG. In addition, the arrow of the line segment shown in a figure represents the flow of a refrigerant | coolant or water.

The main components of this device are a heat source device 2 that generates a heat source for heating and cooling the aquaculture water in the breeding aquarium 19, and a culture that is heated and cooled using the heat source of the heat source device 2 A water tank 19 for storing the water, the temperature adjusting water tank 12 for storing the aquaculture water, and the water for aquaculture stored in the temperature adjusting water tank 12 for breeding aquatic organisms are essential.
In addition, a room and a building for storing the essential components in the previous term are actually required.

In this example, the heat source device 2 is configured by using a room named the air conditioning room 3 or a cold / hot storage 6 arranged in the room. An air conditioning indoor unit 4 is arranged inside the air conditioning room 3 and an air conditioning outdoor unit 5 is arranged outside. For example, when the room is cooled, the air conditioning indoor unit 5 absorbs heat to cool the indoor air.
This cooled air corresponds to a heat source.

In the room, a heat medium heat exchanger 7 for absorbing the heat source generated in the air conditioning room 3 is arranged, and the heat medium circulating in the heat medium heat exchanger 7 absorbs the heat of the heat source.
The heat medium absorbs the heat of the heat source and then transfers the heat to the aquaculture water through the aquaculture water heat exchanger 7 and then is sent to the heat medium recovery tank 8 in the air conditioning chamber 3.
The heat medium is circulated in this way by the heat medium circulation pump 9.
As the heat medium, many fluids can be used, but water is often used in view of practicality.

The aquaculture water is supplied to the temperature adjusting water tank 12 through the intake pipe 16. In some cases, water is taken from the outside, but the aquaculture water is filtered and reused.
Moreover, the filtration apparatus 14 may be arrange | positioned in the temperature control water tank 12, and the water for aquaculture may be filtered with it.
In this case, if the air sent to the filtration apparatus 14 is sent from the air pump 10 installed in the air-conditioning chamber 3, it is convenient because the air heated and cooled by the heat source can be used.

The aquaculture water in the temperature-adjusted water tank 12 is sent to the breeding water tank 19 in the breeding room 17 by the water pump 15 arranged in the water storage room 11. Thereby, the noise and vibration of the water pump 15 are not transmitted to the breeding water tank 19.
The air-conditioning room 3 is provided, the air-conditioning indoor unit 4 is provided inside the air-conditioning room 3, and the air-conditioning outdoor unit 5 is provided outside, and the temperature inside the air-conditioning room 3 is heated and cooled. A heat medium heat exchanger 7 is installed in the air conditioning chamber 3, and the heat medium is circulated in the heat medium exchanger 7 to heat and cool the temperature of the heat medium in accordance with the air temperature in the air conditioner 3 room.

Further, the heat medium heat exchanger 7, the heat medium recovery tank 8, the heat medium heat exchanger 7, and the heat medium circulation pump 9 may be installed in the refrigerator 6 installed in the air conditioning 3 room.
The heat medium is sent to the aquaculture water heat exchanger 13 disposed in the temperature control water tank 12, and after the water for cultivation is heated and cooled, it is sent to the heat medium recovery tank 8 provided in the air conditioning chamber 3. The heat medium is circulated using the heat medium circulation pump 9.

  It is preferable to insert a filtration device 14 into the temperature-controlled water tank 12 to filter impurities in the aquaculture water. In that case, if the air pump 10 which sends the air which the filtration apparatus 14 requires is arrange | positioned in the air-conditioning room 3, it will help heating and cooling of the water for aquaculture.

  By using this aquatic aquaculture system 1, the geographical conditions that can be cultivated can be greatly expanded. In addition, it may be possible to revive aquatic aquaculture that has been unable to be cultivated in recent years due to the effects of global warming even in regions and organisms that can be cultivated.
