Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a system for activating fish habitat in a breeding tank using a jet generator. More specifically, the present invention relates to a system for adding oxygen and sodium hydroxide to a jet flow generator, mixing, stirring and jetting the jets to activate the seafood in the breeding tank.
[0002]
[Prior art]
For transporting live fish including shrimp, various methods such as lowering the water temperature and putting the fish into an anesthetized state have been tried. Ideally, the live fish should be kept fresh for a long time when caught, and be delivered to the user in a fresh state. Oxygen concentration in the habitat affects the freshness of live fish. In addition, the habitat contains carbon dioxide, which has a great influence on the concentration of carbon dioxide. Generally, fish and shellfish consume oxygen during transportation and emit carbon dioxide.
[0003]
As a result, the proportion of the oxygen concentration in the habitat will decrease. In addition, the habitat becomes acidic, the pH value decreases, and the living environment of fish and shellfish deteriorates. In seafood, when the concentration of carbon dioxide in the blood increases, the oxygen binding rate of hemoglobin decreases. As described above, when the concentration of carbon dioxide increases, the survival rate of fish and shellfish also decreases, and the meat quality of fish and shellfish also changes. Therefore, a method of keeping the concentration of carbon dioxide as low as possible has been conventionally performed. As this conventional technique, a method of reducing the concentration of carbon dioxide in sardine cultivation has been proposed (for example, see Patent Document 1).
[0004]
This method circulates a part of the cultivation water, cools the circulating water to maintain the temperature of the cultivation water at a low temperature in a range of 0 ° C. to 25 ° C., and circulates the circulating water using air or oxygen gas. By aeration, partial release of carbon dioxide is performed together with dissolution of oxygen. The circulating water is then treated with a carbon dioxide absorbing agent to remove residual carbon dioxide. Then, the treated circulating water is returned to the cultivation water tank to supply oxygen to the cultivation water and to maintain the carbon dioxide concentration in the cultivation water at 10 ppm or less.
[0005]
Further, in the conventional technology, a circulating filtration device connected to a breeding aquarium is provided with an organic matter degrading bacterium culturing tank, a denitrifying bacterium culturing tank, and the like so that fish and shellfish can be bred for a long period of 6 months or more. (For example, see Patent Document 2). Further, there is a conventional technique in which an air supply means or the like for sucking air by a jet flow is provided in a flow path for circulating water in a water tank to decompose ammonia and the like in the water tank to purify the fish solution tank ( For example, see Patent Document 3).
[0006]
However, in recent years, requirements for habitat environmental standards have become more severe, and it has been desired to develop an activation method that is more efficient than conventional techniques. The present applicant has proposed a jet box in which organic substances and the like are decomposed by generating cavitation or oxygen and water are mixed and stirred (see Patent Document 4). Since this jet generating box is mainly for generating cavitation, it does not efficiently mix oxygen and breeding water and generates cavitation, so that it is not good in energy efficiency.

[Problems to be solved by the invention]
There are various forms, such as a case where fish and shellfish live as a live fish for a long time, a case where they live in an aquarium for ornamental use, a case where aquaculture is performed for aquaculture, and a case where they are transported as a live fish. 2. Description of the Related Art Conventionally, for the purpose of maintaining a habitat for a long time, various measures have been taken, such as lowering the temperature of a water tank, supplying air, and sleeping fish and shellfish themselves. Causes of the deterioration of the habitat include oxygen deficiency, accumulation of carbon dioxide, pollution due to excretion, a decrease in pH value accompanying these, and proliferation of bacteria.
[0009]
Each of these measures has been conventionally implemented, but over a long period of time, particularly, the accumulation of carbon dioxide is relatively associated with oxygen deficiency, and has a serious problem, such as an increase in water temperature. It is well known that phosphate components eluted from excrement and the like undergo a binding reaction with calcium ions and the like in water to cause deterioration in water quality such as a decrease in alkalinity, that is, a decrease in pH value. A specific phenomenon caused by this is that, in the physiology of fish, the efficiency of the oxygen binding reaction decreases due to the decrease in CO ₂ and the pH value of the hemoglobin in the blood which has increased.
[0010]
As the amount of carbon dioxide in the water tank increases, the amount of oxygen relatively decreases. Therefore, when a large amount of carbon dioxide is present, the bond between hemoglobin and oxygen is broken, and the oxygen binding rate of hemoglobin decreases. That is, since the fish and shellfish in the aquarium constantly breathe and excrete, the excreted carbon dioxide accumulates in the aquarium. For this reason, the water in the aquarium tends to be acidic. When the amount of dissolved carbon dioxide increases, the excretion of carbon dioxide from fish and shellfish is suppressed, and the blood concentration of carbon dioxide increases. This leads to a decrease in the pH value and a substantial decrease in the amount of dissolved oxygen.
[0011]
In addition, many aquariums, such as chemical substances, inhibit the binding of hemoglobin to oxygen. Yet a further phenomenon is that shells are delayed in shell shape after molting, which also causes cannibalism. None of the conventional techniques described above is effective against these phenomena, and further improvement is desired.
[0012]
The present invention has been made based on the aforementioned social environment and technical background, and achieves the following objects.
An object of the present invention is to provide an activation system for fish and shellfish that supplies oxygen and sodium hydroxide to a jet generating device to activate the shellfish seawater in the breeding tank and stably inhabit the shellfish seawater for a long period of time. It is in.
Another object of the present invention is to increase the purification effect, reduce carbon dioxide, increase the dissolved oxygen concentration, increase the pH value, prevent acidification, and supply activated seawater habitats that provide activated water. It is to provide an activation system.
Still another object of the present invention is to achieve the compactness and low cost of the system by supplying the active water from the active water tank to one or more breeding tanks by using gravity, that is, by natural flow due to a head. It is an object of the present invention to provide a system for activating seafood habitat.

FIG. 2 is a plan view showing a jetting device for the present invention.
[0019]
The system for activating seafood habitat comprises a seafood habitat activating device 1 and a breeding tank 2 for seafood habitat to which activated activated water is supplied. The activated water activated by the seafood habitat activating device 1 is supplied to a seafood aquarium or breeding tub 2 to be activated through a supply pipe 50, and the seafood lives in the breeding tub 2. I have.
[0020]
In the fish and shellfish living water activating device 1, a tank 4 as an active water tank is provided on an upper portion of a base 3, and a filtration tank 15 is provided on a lower portion of the base 3. A drain pipe 61 is provided between the tank 4 and the filtration tank 15, and when the activated water in the tank 4 has a predetermined height or more, the activated water is drained to the filtration tank 15. The filtration tank 15 contains a filtration member such as MgOH.CaCO ₃ . An oxygen supply device 5 and a chemical solution injection device 6 are provided adjacent to the tank 4. Further, a jet flow generating device 7 is incorporated in the tank 4.
[0021]
An oxygen supply device 5 and a chemical solution injection device 6 are connected to the jet flow generation device 7 via a pipe (not shown). Oxygen is supplied from the oxygen supply device 5 and hydroxylation is performed from the chemical solution injection device 6. Sodium is supplied to the jet generator 7. The oxygen supply device 5 opens the valve of the oxygen cylinder, for example, by adjusting the regulator to 1 l (liter) / min or 2 l (liter) / min, and supplies oxygen to the jet generating device 7. This oxygen supply is controlled by the habit of fish and shellfish. For example, a nocturnal shrimp or the like may use only oxygen contained in the air during the day, or may supply oxygen only during the night. Therefore, the oxygen supply device 5 is not always essential.
[0022]
The chemical liquid injector 6 is composed of a metering pump or the like, and is effective when the fish and shellfish are allowed to swim long and quietly for breeding, and is set by a timer in consideration of a decrease in the pH value. It operates for a specified time and is supplied with sodium hydroxide as a pH adjuster. The supply amounts and supply times of the oxygen and sodium hydroxide are set according to the conditions of the breeding tank 2. The water to be controlled, such as breeding water or habitat water, or seawater is controlled so as to always maintain the pH in a set range. A control panel (not shown) for the operation and control is provided adjacent to the tank 4, the base 3, and the like.
[0023]
As described above, all the devices are mounted on the base 3 and are compact. Therefore, when this device is moved, it can be easily performed by lifting the base 3. The fish and shellfish inhabiting water in the filtration tank 15 is supplied from a discharge port 15 a provided in a lower part of the filtration tank 15 to the jet generating device 7 via a pump 12 via a supply pipe 13. In other words, the seafood of the fish and shellfish circulates through the breeding tank 2, the collection pipe 62, the filtration tank 15, the pump 12, the supply pipe 13, and the jet generator 7, and is activated.
[0024]
The fish and shellfish aquatic tank to be activated is, for example, a tank for transporting live fish, a tank for temporary storage during transportation, a tank for aquaculture, and a rearing tank 2 for ornamental aquariums such as goldfish. The habitat to be activated in the breeding tub 2 is collected in the filtration tub 15 of the fish and shellfish habitat activating device 1 through the collection conduit 62. The collected habitat is filtered in the filter tank 15 as described above, and is supplied with oxygen and sodium hydroxide by the jet generator 7 to be mixed and stirred.
[0025]
The mixed and stirred habitat is activated and stored in the tank 4. Activated water is supplied to the breeding tank 2 from a discharge port 4 a provided at the lower part of the tank 4 via a supply pipe 50. Since the entire tank 4 is disposed at a position higher than the breeding tub 2, the activated water is supplied to the breeding tub 2 from the tank 4 in the form of a natural flow due to a head due to gravity. The supply pipe 50 includes a supply pipe 51, a flow control valve 52, and a flow meter 53, and is connected to an ejection device 54 having a plurality of nozzles 55 as shown in FIG.
[0026]
That is, the activated water having a predetermined flow rate adjusted by the flow control valve 52 is supplied to the breeding tank 2. At a position separated from the bottom of the breeding tub 2 by a predetermined distance, there is provided a middle board 2a in the shape of a mushroom or a perforated board through which active water can pass. A filter sand portion 14 on which sand 14a is deposited is provided. The nozzle 55 of the jetting device 54 is provided between the bottom plate portion of the breeding tub 2 and the filter sand portion 14 and jets out from a plurality of jetting holes 55 a formed in the nozzle 55. Then, the activated water that has been activated passes through the filter sand part 14 and is supplied to the habitat of the breeding tub 2 where fish and shellfish such as shrimp live.
[0027]
Habitat containing pollutants such as fish and shellfish excrement and contaminated and requiring activation is collected in the filtration tank 15 from above the breeding tank 2 via the collection pipe 62. As described above, the supply of activated water from the tank 4 to the breeding tank 2 and the collection of habitat requiring activation from the breeding tank 2 to the filtration tank 15 require power from a pump or the like. Therefore, the configuration of the system can be simplified. Also, as shown in FIG. 3, even if there are a plurality of (five in this embodiment) breeding tubs 2a, 2b,...
[0028]
Also, the supply of the activated water from the tank 4 to the breeding tank 2 is a natural flow utilizing a head, and the activated water flows out from the lower part of the breeding tank, so that an environment suitable for fish and shellfish is provided. It becomes. When the tank 4 has to be emptied for maintenance or the like, the activated water in the tank 4 is supplied to the outside by the lower drain valve 17a, and the living water in the breeding tank 2 is supplied to the outside by the lower drain valve 17 or the filtration tank. 15 can be drained.
[0029]
Next, the jet generating device 7 which is a main part of the fish and shellfish habitat activating device 1 will be described. Referring to FIG. 4, the principle of jet generation by the jet generation device 7 according to the present invention will be described. This jet generation principle uses the Coanda effect to generate a jet. FIG. 4 is an explanatory diagram schematically showing the jet flow generating device 7.
[0030]
In general, cavitation must be avoided in a hydraulic machine or the like because it causes vibration, corrosion or damage of the material. However, in the seafood habitat activation apparatus 1 of the present invention, the oxygen concentration of the habitat is improved, and This phenomenon is actively used. Cavitation does not occur wherever Bernoulli's theorem holds.
[0031]
The Coanda effect described above refers to a phenomenon in which a fluid is drawn to a wall. In a jet, a water jet is drawn to a wall of the internal space V to generate a vortex. Further, the jet has a transmission phenomenon in which vortices alternately occur on the left and right. This Coanda effect will be described with reference to FIG. The jet generating box 20 which forms the base of the jet generating device 7 is a flat rectangular body. It is arranged so that the longitudinal direction is vertical. On the upper surface of the jet generating box 20, an injection nozzle 21 for supplying pressurized habitat and the like from a pump unit 26 and injecting the water downward is fixed.
[0032]
The injection nozzle 21 is an annular space having a cylindrical cross section. Inside the jet generating box 20, a divided jet generating chamber 22 is formed. The internal space V of the jet generating chamber 22 is a three-dimensional box-shaped space which is flat, and represents a general height of the space H and a general width thereof W, and a length in a vertical (vertical) direction. Let L1 be the effective diameter of the opening of the injection nozzle 21 and D1 <H, W / H> 4, and H <L1 as the conditions for generating the eddy current, as described above. However, it is preferable that W <L1 in addition to the above relation. The main jet 23 jetted from the jet nozzle 21 is jetted in the direction of the approximate center line of the internal space V in the vertical direction.
[0033]
When the main jet 23 is injected, an adhesion vortex 24 that is a low-pressure vortex is generated at the eight corners of the jet generation chamber 22 by the Coanda effect, and an adhesion jet is generated in the main jet 23. FIG. 4 shows a state in which the main jet 23 flows in the jet generation chamber 22 while being split in any of two directions. However, since this flow is unstable, the flow is switched to the other flow. That is, the main jet 23 is unstable and generates a flow while swinging. These jets have a function of uniformly mixing and agitating gas such as habitat and oxygen, and habitat and liquid such as sodium hydroxide. The jet containing the air bubbles miniaturized in the internal space V is discharged from the discharge port 27 into the tank 4.
[0034]
The Coanda effect is effective even if it is not the dimensional condition described above, but preferably the condition described above is effective because a jet with a vortex is generated in the internal space as shown in the figure. This jet becomes a flow which is offset in either direction and swings alternately. FIG. 4 shows an example in which the air suction pipe 25 is arranged at the center of the injection nozzle 21. This is for drawing in air or the like from the atmosphere by the negative pressure of the living water injected from the injection nozzle 21.
[0035]
In the present embodiment, the air supply pipe 25a and the sodium hydroxide supply pipe 25b are connected to the air suction pipe 25 without sucking air from the atmosphere. By generating the jet flow accompanied by the vortex, the bubbles can be made finer as described above, and the dissolved oxygen concentration can be increased.Additionally, sodium hydroxide is added to increase the alkali concentration of the living water. It contributes to raising. Thus, the habitat circulates between the breeding tanks 2 (2a, 2b, 2c, 2d, and 2e), the filtration tank 15, the tank 4, and the like as shown in the block diagram of FIG. .
[0036]
Next, the operation of the fish and shellfish habitat activating device 1 will be described. After setting the chemical solution state, setting the oxygen supply state, setting the timer, etc., turning on each device and confirming the operation, the operation switch on the control panel is turned on and started. Upon start-up, the habitat is sent from the filtration tank 15 to the jet generating device 7 via the pump 12 and is jetted, and then discharged to the tank 4 as activated water activated as described above. The discharged activated water is stored and supplied to the breeding tank 2 using a head as required. All of these operations are performed automatically.
[0037]
As described above, fish and shellfish in the breeding tank constantly excrete carbon dioxide, and the carbon dioxide has a chemical solubility in water of 28.3% of O ₂ and N ₂ in the air at the absorption coefficient of Bunsen. 54.6 times higher. For this reason, in the aquarium where fish and shellfish live, the discharged CO ₂ rapidly lowers the pH value of water as in the following reaction formula.
[0038]
CO ₂ + H ₂ O → H ₂ CO ₃ (HCO ₃ ⁻ + H ⁺ )
In order to solve this problem, the present invention solves this problem by causing the above-described jet flow generating device 7 to jet the jet, and at the same time, dissolving the ionized molecules by adding sodium hydroxide (NaOH) as a neutralizing agent. The reaction was carried out as indicated by, to increase the pH value.
[0039]
(Na ⁺ + OH ⁻ ) + (HCO ₃ ⁻ + H ⁺ ) → NaHCO ₃ + H ₂ O
In addition, the jet generator 7 is effective in controlling the rate of addition of the neutralizing agent and allowing the reaction to proceed with fine water droplets. As described above, the activated water that has been activated and stored in the tank 4 is supplied to the breeding tank 2 through the filter sand part 14 by natural flow utilizing a head. Since it is very close to a natural state, there is an effect that the breeding tub 2 becomes an easy environment for fish and shellfish.
[0040]
[Other embodiments]
As described in detail above, the present invention based on the jet flow generating device 7 can be applied to various forms of habitat activation systems. Therefore, it is needless to say that the present invention is not limited to the contents described in the present embodiment. For example, oxygen is supplied to the jet generating device 7 described above, but it may be supplied only by air depending on the breeding fish or the time zone.
[0041]
Further, the nozzle 55 described above may have a curved shape according to the shape of the breeding tub 2. Further, the breeding tank 2 may be provided with an aeration 72 or a protein skimmer for removing invisible fine residual food and mucus by buoyancy of foam. Further, a foam separation device 71 may be provided in the filtration tank 15 to separate and remove bubbles. Further, a heating or cooling device for keeping the temperature of the habitat constant may be provided.
[0042]

Rearing fish and shellfish: shrimp, capacity of rearing tank 2: 1.7 m ² , flow velocity in sand of filtration tank 15: 70 L (liter) / min, oxygen concentration: 100% or more, discharge pressure of pump 12: 68.6 ６6.9 N / cm ² (7 to 0.7 kg / cm ² )
【The invention's effect】
As described in detail above, the present invention uses a jet generator to mix and stir oxygen and sodium hydroxide into fish and shellfish habitat recovered from a breeding tank to form active water in a jet state. Was supplied to the breeding tank. As a result, an activation system has been achieved in which fish and shellfishes requiring a delicate environment such as shrimp can stably inhabit for a long time. In addition, habitat water was able to reduce carbon dioxide, increase the concentration of dissolved oxygen, and increase the pH value to prevent acidification and obtain activated water.
[0043]
Furthermore, the activation device for the fish and shellfish habitat can be supplied at a high position to supply the activated water from the activated water tank to the breeding tank by natural flow utilizing a head, so that it is compulsorily required. There is no need for a pump to supply, and the system is compact and low-cost. In particular, it is effective when distributing and supplying activated water from one activated water tank to a plurality of breeding tanks.
