Field of the Invention The present invention relates to an aquarium device for transporting live fish, and more specifically, to attenuating the oscillation of water in a fish tank to prevent the oscillation of the fish itself, and to eliminate waste from live fish. The present invention relates to an aquarium device for transporting live fish, in which water in the fish tub is purified by things so that the live fish in the fish tub can be transported in a state closer to its natural state.

[0002]

2. Description of the Related Art Conventionally, when transporting live fish, in the case of short-distance transport, the fish were simply put in a fish tank and covered with a lid. As a result, the long-distance transportation is gradually being carried out, and for that reason, an oxygen supply device is installed in the fish tank, and a device for filtering waste sewage in the fish tank is mounted on a truck for circulation filtration. There is.

[0003]

However, in the conventional aquarium device for transporting live fish, a space is provided above the water surface from the surface of oxygen supplementation without filling the water in the fish tank. When the car starts, stops, turns right, turns left, or curves, the water in the fish tank constantly shakes, hinders the natural swimming of live fish, weakens live fish, and spits out dirt, and excrement of feces increases. As a result, the amount of ammonia generated increases, the fish become crazy, even the live fish of the corner will be damaged or tired when it arrives, and if the oxygen is excessive, the internal organs will rot and the body of the live fish will soften, etc. There was a problem that the freshness and taste fell. In addition, as a filtering device for a device that transports water in a fish tank while filtering it, many of them only use a filter for filtration, and this also involves a problem that it is not possible to sufficiently purify the aged wastewater. . Further, the fish caught by a fishing boat or the like is placed in an aquarium in the ship and transported to a fishing port. However, even in such a case, the same problem as in the case of the above-mentioned truck transportation occurs.

The present invention has been made in view of the above-mentioned problems, and its object is to reduce the fluctuation of water in the fish tank to prevent the fluctuation of the fish, and Cleans the water in the fish tank due to the wastes generated from the fish tank so that it can be cleaned more beautifully and the live fish in the fish tank can be transported by a transporter such as a truck or a ship in a state closer to its natural state. An object is to provide an aquarium device for transporting live fish.

[0005]

In order to achieve the above object, the aquarium device for transporting live fish according to claim 1 of the present invention has a purified water inlet at the upper part of the aquarium and a waste water outlet at the lower part of the aquarium. A fish tank having the same and a sewage supply unit for supplying sewage in the fish tank are provided, and compressed air is jetted below the sewage supply unit to agitate and aerate sewage supplied from the sewage supply unit. By providing a filtration active tank for separating purified water and suspended matter, the filtration active tank is formed from a plurality of layers having at least a filtration layer and a cooling layer consisting of a heat exchanger such as a heat exchange coil, It has a pump for pressurizing the purified water obtained in the filtration active tank into the fish tank so as not to create a gap, and the fish tank and the filtration active tank are provided side by side with a transporter such as a truck or a ship. Further, the aquarium device for transporting live fish according to claim 2 is the aquarium device according to claim 1, wherein the active filtration tank has a filtration layer, an activated carbon layer made of charcoal or the like, a coral layer, and a cooling layer. However, the lower layer of the filtration active tank is provided with a compressed air jetting portion for jetting compressed air.

FIG. 3 is a vertical cross-sectional view of a filtration active tank of an aquarium device for transporting live fish.

The water tank apparatus for transporting live fish according to this embodiment is roughly classified into two tanks, a fish tank 1 and a filtration active tank 2. The fish tank 1 is made of a lightweight reinforced plastic plate material, the ridge is rounded to prevent dirt from collecting at the corners, and a live fish outlet is provided at the ceiling, and a lid 3 is provided at the outlet. It is provided to open and close. In the closed state of the lid 3, the lid 3 should not be opened by water pressure, and has a watertight and robust structure. The lid 3 is provided with a transparent protruding valve 4 for venting air. Further, an introduction pipe 5 for introducing filtered active water is connected to the ceiling of the fish tank 1, and a suction valve 7 is provided in the introduction pipe 5. Further, a drain pipe 6 equipped with a drain valve 8 is connected to the bottom side surface of the fish tank 1 and is connected to the filtration active tank 2. Then, as shown in FIG. 1, the introduction pipe 5 is attached to the upper side wall portion of the fish tank 1, along the inner wall surface, and at the corner position 1a where the activated filtered water can be introduced so as to be parallel to the water surface, The discharge pipe 6 is attached to a lower side wall portion of the fish tank 1 at a corner position 1b along which the inner wall surface can be discharged. In this way, in the fish tank 1, it is possible to prevent turbulent flow of the filtered active water from causing a gentle regular water flow along the inner wall surface of the tank. Here, although the roundness of the ridge (corner) varies depending on the size of the tank, it is formed into at least a radius having a radius of 20 to 30 cm or more. This makes it possible to obtain the gentle regular water flow described above.

The filtration active tank 2 includes a sewage supply section 21 for supplying sewage from the fish tub 1 in a shower shape, and a filter layer 22 for filtering sewage supplied from the sewage supply section 21.
From the coral grains (powder) or coral fossil limestone to which the activated carbon layer 23 for adsorbing and treating the filtered water filtered by the filtration layer 22 with the activated carbon and the microorganisms for aerobically treating the wastewater adsorbed by the activated carbon are attached. It is composed of a coral layer 24, a cooling layer 25, and a compressed air jetting portion 26 for jetting compressed air to the cooling layer 25.
The active filtration tank 2 is connected to the lower part of the fish tank 1 and the drain pipe 6 through the drain valve 8 and the fish tank 1 in the sewage supply unit 21.

The sewage supply part 21 is a part for uniformly discharging sewage introduced from the lower part of the fish tank 1 to the filtration layer 22 and discharging the aerated air. A flat container having nozzles on the lower surface is connected in parallel so that the sewage in the fish tank 1 containing feces or the like is uniformly showered in the lower filter layer 22. In addition, this sewage supply unit 21,
It may be configured so as to dilute the sewage, and may be configured by providing a plastic plate having a plurality of small holes for precipitating the sewage in the fish tank 1 from above to shower the sewage.

The filtration layer 22 is a layer for sieving the suspended matter in the aged wastewater from the fish tank and is filled with a filter. As the filter, a wire mesh, a filter cloth, a filler or the like is used so as to screen the suspended matter. Floating matter such as feces is removed from the sewage of the fish tank 1 in which the feces and the like are showered from the sewage supply unit 21 by gravity separation and sieving, and the sewage is evenly deposited on the upper surface of the activated carbon layer 23. As described above, the filter layer 22 has fine meshes.

The activated carbon layer 23 is a layer for adsorbing and removing organic pollutants and the like dissolved in the sewage of the fish tank 1, and is filled with granular charcoal or activated carbon (filling a net container or the like. It may be formed, or powdered activated carbon or the like may be used). When using a small particle size, it is necessary to fill the net container so as not to be scattered by the rising compressed air. In this case, if the height of the activated carbon layer 23 is increased and a large amount of air is used to flow the activated carbon, the adsorption efficiency can be increased. This activated carbon layer 2
In 3, the sewage contacts the rising air and is adsorbed by activated carbon while being aerated. The sewage adsorbed by the activated carbon layer 23 is deposited on the lower coral layer 24 of microbial activity.

The coral layer 24 is a layer formed by filling coral (coral) particles or powder 24a to an appropriate thickness, and is purified by alkaline treatment with calcium carbonate to form coral, and the surface of the coral. The aerobic microorganisms attached to the bacterium are grown, and the action of the microorganisms removes annia and other contaminants. Sewage treated with calcium carbonate, which is a component that forms coral in the coral layer 24, falls in the lower cooling layer 25 that follows this layer.

The cooling layer 25 is a layer for cooling the temperature of the purified water, which has been processed up to the coral layer 24 to remove pollutant components and purified, to the water temperature of the fish tank 1, and the cooling coil 25a of the filtration active tank 2. It is arranged over the entire surface of the opening cross section. The cooling coil 25a is connected to the cooling device 11 so that the refrigerant flows in the pipe and the purified contaminated water is brought into precipitation while coming into contact with the surface. Coral layer 24
In the cooling layer 25, the temperature of the purified water treated in (2) is adjusted while being mixed with the compressed air rising from the compressed air jetting section 26 below.

The compressed air jetting portion 26 is a portion for jetting compressed air to the purified water that is precipitating and mixing the air to obtain filtered active water, and is composed of a compressed air jetting hole member 26a. Compressed air is mixed with purified water whose temperature is adjusted in the cooling layer 25 to increase oxygen dissolved in the purified water supplied to the fish tank, and micro air bubbles are entrained in the purified water to generate filtered active water. I have to. Micro air bubbles in the fish tank improve blood circulation in the fish and are effective in preventing internal rot. In addition, since the oxygen dissolved in the purified water can be kept high on average, the generation of bacteria is promoted, while it has the effect of killing various bacteria.

In addition, in the location adjacent to the filtration activation tank 2,
A machine room 10 is provided, and a cooling device 11,
A compressor 12, a pump 13, etc. are stored. During transportation (especially in summer), the purified water is cooled by the cooling device 11 in order to maintain the water temperature in the fish tank 1 at a required temperature. The cooling device 11 supplies a refrigerant to the cooling coil 25a to cool the purified water, and at the same time, to cool the compressed air aerated in the filtration active tank 2 to improve the filtration efficiency. Alternatively, the compressed air obtained by compression with the compressor 12 may be cooled in advance by the cooling device 11, and the cooled air may be sent to the compressed air ejection hole member 26a and ejected upward.

The compressor 12 is a device for supplying compressed air in order to mix purified air with air so that the purified water contains sufficient air bubbles to dissolve oxygen. The compressed air obtained here is sent to the compressed air ejection hole member 26a. Pump 1
3 is provided in the filtered water introduction pipe 5 connected to the suction valve 7, is connected to the purified water inlet in the upper part of the fish tank 1, and the pump 1
By the operation of 3, the filtered activated water is introduced into the purified water inlet. A discharge valve 8 is provided in the middle of the discharge pipe 6 for discharging the wastewater, and is connected to the wastewater supply unit 21.
The waste wastewater is led to the wastewater supply unit 21 via the discharge valve 8 of the discharge pipe 5 by the supply pressure of the filtered activated water. As a power source for the machine room 10, a battery may be mounted on a transportation vehicle and a charging generator may be provided.

Next, the operation of this embodiment will be described.
During transportation of live fish, the water in the fish tank becomes sewage due to waste products generated from the live fish body. Therefore, the pump 13 is operated, the discharge valve 8 of the fish tank 1 is opened, and the suction valve 7 of the filtered water introducing pipe 5 is opened. When opened, the filtered activated water is pressurized by the pump 13 and the purified water inlet is also pressurized, the pressure in the fish tank 1 rises, and the waste effluent passes through the discharge pipe 6 to reach the filthy water supply section of the activated filter tub 2. 21. Here, the sewage is made into smaller water droplets on a plastic plate having a plurality of small holes and is showered on the filtration layer 22. At the same time, the sewage is discharged by cooled compressed air rising from below. It is naturally cooled with a plastic plate. Then, the sewage that has fallen below the sewage supply unit 21 is first mixed in the filtration layer 22 with the compressed air by stirring to increase the amount of dissolved oxygen in the sewage to form a bubble, and the bubbles generate the bubbles. Waste such as waste is adsorbed and separated into wastewater and suspended matter due to the difference in specific gravity. After the suspended matter is separated by the filtration layer 22 and filtered,
Sewage drops into the activated carbon layer 23 and is adsorbed by the activated carbon.

In the activated carbon layer 23, the sewage is treated with the activated carbon, and the waste products dissolved in the sewage are adsorbed and removed. Furthermore, sewage is microbially active coral layer 2 below this.
4, the polluted components remaining in the wastewater treated by the calcium carbonate discharged from the coral 24a are removed, and purified water is obtained. Then, while being agitated and aerated by the compressed air injected from below in the cooling layer 25, the surface of the heat exchanger 25a such as a cooling coil is cooled. Then, in the compressed air jetting section 26, the purified water is mixed and liquefied with the compressed air by stirring and mixing, and the amount of dissolved oxygen in the purified water is increased to form bubbles and become activated water for filtration. This filtered active water falls and is stored in the lower filtered water reservoir, and the suspended matter on the filtering layer acts so as to be separately discharged to the outside of the filtering active tank 1. Further, since the filtered and purified water is cooled in the cooling layer 25 while being stirred and mixed by the compressed air, the water temperature is appropriately adjusted. In this way, the waste water is purified while flowing down the filtration active tank 2, and the air is mixed and the water temperature is also lowered to be dropped and stored in the filtered water reservoir.

Then, the pump 13 introduces the clean filtered active water of the filtered water reservoir along the upper inner wall surface of the fish tank 1 so that the water level comes to the air vent protruding pipe (Because the protruding pipe is transparent. The water level is known.), Of course, the inside of the fish tank 1 is completely filled with water, and a predetermined roundness is formed at the corners of the fish tank 1, so that the filtered active water flows along the inner wall surface of the fish tank 1. A gentle water flow can be generated in the fish tank 1, and acts so as not to cause a wave motion in the fish tank 1 when the transport vehicle is started, stopped, or when the speed is high or low or when the vehicle is curved. Moreover, the water pressure due to the pump pressure acts so as to obtain a state close to the natural water pressure.

It should be noted that the present invention is not limited to the above-described examples, and includes configurations that can be modified and implemented within the scope of the present invention. For example, the layers of the filtration active tank may be a filtration layer, a coral layer, an activated carbon layer, and a cooling layer in this order from the top or the layers without the coral layer. Further, in the above-described embodiment, the case where the transporter is a truck for land transportation has been described, but the same applies to a marine transportation ship. In this case, the configuration will be applied to the fish tank or "ikesu" installed on the ship. And as the water used here, seawater can be applied.
