Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a live fish water filter, and more particularly to a low-cost, small-sized, and light-weight filter that is used by putting it in live fish water. The water filtering apparatus for live fish of the present invention is particularly used for filtering live water for live fish such as live fish transport containers, small live fish transport vehicles, and live fish transport cases for fishermen.

[0002]

2. Description of the Related Art As a live-fish water filtering apparatus, a large-sized apparatus fixedly arranged in a fixed-water tank for live-fish and a large-sized apparatus mounted on a large-sized live fish carrier are already known. On the other hand, as for the live fish carrier, there has been no small-sized filter device in the past, and only means of injecting oxygen into water by an air pump is adopted.

[0003]

The above-mentioned live fish water filtration device fixedly arranged in a live fish fixed water tank is a large fixed installation type large-scale device that involves electrical work and piping work, and is used for filtering live fish carrying water. Cannot be used for. In addition, the water filter for live fish mounted on a large live fish carrier is also a fixed and large-sized and expensive device, which is used only for transportation between the production area and the market, and a small amount of live fish. It is difficult to use when transporting from the market to the place of consumption. On the other hand, if the only means of injecting oxygen into the water in the live fish carrier is taken, there is a problem that the mortality rate of fish during transportation is high because the water cannot be purified. Therefore, air mail is often used to reduce the mortality of fish during transportation by reducing the transportation time. However, the use of airmail will inevitably increase the cost of transporting live fish. In view of the above points, the present invention provides a low-cost, small-sized, and lightweight live-water filter for live fish, such as a live-fish transport container, a small-sized live fish transport vehicle, and a live fish transport case for a fisherman. It was made in an attempt to provide.

[0004]

In order to solve the above problems, the present invention provides a case with a water suction port and a water discharge port, and the water is provided between the suction port and the discharge port in the case. A live fish water filtering device characterized in that a filter blade is filled with a filter material, a pump blade that is rotated by a motor is provided in the vicinity of the discharge port in the case, and a battery as a power source of the motor is further provided in the case. Claim 1) is provided.

It is desirable to use activated carbon, oyster shells and zeolite as the filtering material (claim 2).

[0006]

[Action]

[Water filter for live fish according to claim 1] The water filter for live fish according to claim 1 is used by putting it in water for live fish such as a live fish transport container, a small live fish transport vehicle, and a live fish transport case for anglers. A pump blade provided in the vicinity of the discharge port in the case is rotated by a motor to suck in live fish water from the suction port of the case and send it out of the case from the discharge port. At this time, the live fish water is filtered by the filtering material by passing through the filtering material filled between the suction port and the discharging port in the case, and is sent out of the case from the discharging port in a purified state. Thus, as a result of the live fish water being filtered and purified, the survival rate of fish during transportation is significantly increased.

[Water filtration device for live fish according to claim 2]
In the water filter for live fish of, activated carbon, oyster shells and zeolite are used as the filtering material. Activated carbon decolorizes and deodorizes live fish water, oyster shells supplement calcium in live fish water, and zeolite removes ammonia in live fish water.

[0008]

Next, an embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 is a case of a water filtering device for live fish. The case 1 in the illustrated example is a substantially cylindrical body formed by screwing a main body 1a and a head 1b, and a cap 5 is screwed to the head 1b via a packing 3. Also, case 1
Is equipped with roll-preventing square plates 7 and 9 at the end of the main body 1a and the end of the head 1b, respectively. The case 1 is provided with a water suction port 11 and a water discharge port 13. In the illustrated example, the suction port 11 is provided at the end of the main body 1a in the case 1, and the discharge port 1 is provided in the head 1b of the case 1.
It is equipped with 3. A filter 15 is attached to the inside of the suction port 11. The filter 15 prevents foreign matter such as dust from entering the case 1.
A filter material 17 is filled between the suction port 11 and the discharge port 13 in the case 1. It is desirable to use activated carbon, oyster shells and zeolite as the filter material 17, but coral scraps and the like may be used. Reference numeral 19 is a filter material holding net, and reference numeral 21 is a net holding material. A pump blade 25 rotated by a motor 23 is provided near the discharge port 13 in the case 1. The pump blade 25 sucks live fish water from the suction port 11 and sends it out from the discharge port 13. Reference numeral 27 is a pump portion fixing member, 29 is a vibration-proof rubber, and 31 is a water passage for cooling the motor 23. Further, a battery 33 as a power source of the motor 23 is arranged in the case 1. Reference numeral 35 is a packing.

【The invention's effect】

[Water filtration device for live fish according to claim 1] The water filtration device for live fish according to claim 1 is a low-cost, small-sized, and lightweight filtration device, and is used for live fish water such as live fish transport containers, small live fish transport vehicles, and live fish transport cases for fishermen. It can be used by throwing in. Since this live fish water filtration device filters and purifies live fish water, the survival rate of fish during transportation is increased, and live fish can be transported for a relatively long time. Therefore, it is possible to switch the transportation of live fish using a small live fish transportation container, which has conventionally depended on air mail, to land transportation, and it is possible to significantly reduce costs. In addition, claim 1
By inserting the water filtration device for live fish in a live fish transport container, a small live fish transport vehicle, etc., it becomes possible to easily and inexpensively transport live fish not only between the production area and the market but also from the market to the consumption place. Become. Furthermore, by putting the water filtering device for live fish of claim 1 in a live fish carrier case for fishermen,
A fisherman can take home the fish he has caught and bring it home.

[Water filtration device for live fish according to claim 2]
In the water filter for live fish, the activated carbon used as a filter material decolorizes and deodorizes the live fish water, the oyster shells supplement calcium in the live fish water, and the zeolite removes ammonia in the live fish water. Therefore, the survival rate of fish during transportation is significantly increased.
