Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container for live fish used for transporting live fish such as adult fish for cooking to restaurants and the like, and young fish for release.

Conventionally, as shown in Figure 1, the method of transporting live fish is to use a container l in a flexible packaging made of a material such as plastic wrapper, with a water level that leaves an appropriate space 6 at the top of the container 1 through the opening 2 in the second part. There is a method of filling the tank with water 4 until the tank is filled with live fish 5, blowing oxygen into it, tying the upper part 2 with lobes 3, and transporting the tank in a sealed state. However, when transported by truck using this method, the vehicle may vibrate or start moving during transportation.

Due to the repetition of stop 1-, the water 4 moves up and down, left and right, and due to the slope and bubbles, the live fish 5 come into contact with each other and collide with the container 1, resulting in a high rate of death due to trauma and fatigue. There was a drawback.

In addition, as shown in Figure 2, using a rigid container 7 made of a steel plate or 7) with an open top or a cover with an appropriate air vent, place the water in a water bowl 1 at an appropriate water level 1. After sledding, put live fish 5 into a separately provided oxygen cylinder 8, pressure regulating valve 9 and air nozzle lO.

Oxygen bubbles 20 were blown into each hole of the six vessels 7 and N was applied.

There is a method of transporting in i-rack etc. In this case, as in the method shown in Figure 1, due to the movement of the water surface.

Story It had the disadvantage of a high mortality rate due to trauma and fatigue.

The Ishi invention was made in view of the above circumstances, and its aim is to provide 2g of live fish waste that can prevent trauma and fatigue and reduce mortality.

The present invention provides a live fish container with a sealed structure in which a gas-liquid membrane consisting of a hydrophobic porous membrane is placed in the -F section.

In addition to filling the vessel with water, a device r1゛ is installed to supply air or oxygen for the survival of live fish from the bottom of the vessel.

By releasing 4J of gas, the movement of water inside the container during transportation can be minimized, and at the same time, oxygen for the survival of live fish can be continuously supplied, thereby preventing trauma and fatigue of live fish and preventing death. It is possible to reduce the rate.

The present invention will be further described based on an embodiment shown in FIG. The container for storing live fish 5 consists of a container body 11 and a cover 12, and the two sides of the cover 12 are in contact with the water 4 in the container f04! +
It is composed of a hydrophobic porous membrane material 13 such as Teflon forming the IQ and a delunation support 12 such as a punching plate wire mesh protecting the membrane shrine 13. The porous membrane 4A'I8 is a porous membrane having countless pores made of fibers of a hydrophobic material such as Teflon that prevents wetting with water. 01~0

-12 is removably attached to the container body 11 with a bolt screw 1'η via a seal gasket 15. Contents'A: (At the bottom of the main body 11 are an oxygen supply nozzle 16° for supplying oxygen necessary for the survival of the live fish 5 in the form of bubbles, an oxygen supply valve 17 and a, and a water injection/drainage valve 19 for the water 4 in the container. An oxygen pressure regulating valve 9 is installed near the container, and the regulating valve 9 and the oxygen supply valve 17 are connected by a boss or piping 18. There is.

The container constructed as described in 1- below is transported by being loaded onto a small mountain such as a truck.

Next, the effect will be explained.

First, remove the cover 12 and fill it with water directly from the pouring/draining valve 19 or the -1 part ['' section of the container body 11 to an appropriate water level depending on the river of the live fish 5. Next, place the live fish 5 into the container body 11.
After inserting from the upper opening f61, insert the cover 12 into the JIQ center I.

To check whether the water is full or not, provide a viewing window on a part of the -F side of the cover 12, or insert a known overflow pipe (not shown) into the cover 12.

Oxygen is supplied into the oxygen chamber 1 by opening the oxygen supply valve 17 after the pressure of the high ξF oxygen in the oxygen bottle 8 is regulated by the pressure regulating valve 9.

It is blown into the water 4 in the container and dissolved. Undissolved air bubbles rise due to the difference in specific gravity between water 4 and air bubbles 20.

The porous membrane 4'' is in contact with the porous membrane 13.

FIG. 4 is a detailed cross-sectional view of the porous membrane material 13.

11'+i Since the air bubbles 20 in contact with the shrine 13 are pumping oxygen into the water 4 filled in the container, the internal pressure of the container (slightly higher than the air pressure), and this pressure difference causes the air bubbles 20 to
0 passes through the pores 21 from the membrane surface 18b on the water 4 side and exits to the membrane surface 1B and a side on the 2 popular side, so even if oxygen is continuously supplied into the container, Mon 13 and Wed 4
Excess oxygen between the container and the container can be kept almost full.

For this reason, the water in the pot shakes the pot, causing E1-
There are almost no free vibrations on the water surface (2. Live fish in water 5.
However, it does not move as violently as the swaying of the water in the water. This is because when vibrations occur in the width and width during transportation, even if the excitation force applied to the container 24 body 11 as an external force turns into a minute pressure change in the water, the water does not shake. , live fish 5 come into contact with each other.

There is no risk of collision with the container body 11.

Note that the container is not limited to this example.

It may be cylindrical or spherical if necessary.

Even if it is a part of the upper part of a multi-rL type shrine, rather than the entire upper part, it is also L (good).

Also, instead of 8, air may be compressed (air may be blown into the oxygen cylinder due to an emergency, etc.).

As detailed above, a live fish storage container with a water honey structure with a hydrophobic + 1.0 porosity separation membrane on the top is filled with water, and the live fish are removed from the bottom of the container. 17

It has the great effect of being able to eliminate the causes of high injury and mortality rates for live fish during transportation, which has been a problem since then, and is extremely useful industrially.

It should be noted that the present invention is not limited to the transportation device shown in the embodiment described in Section 1, but can also be used as breeding equipment on land.
