Description

[Detailed description of the invention] The present invention relates to a fish farming device.

Conventional fish farming equipment is known that simply circulates water and allows the water to fall onto the water surface to mix air into the water, but the water tends to become contaminated with food and fish excrement (and the water can become contaminated due to the proliferation of bacteria). Fish, such as carp and goldfish, were easily perishable and difficult to keep or raise for long periods of time.

The present invention is a fish farming system that can prevent water from becoming contaminated and rotten, keep the water quality clean at all times, and in particular, make it possible to breed and raise fish that like beautiful water, such as Ame-no-fish, char, sweetfish, etc. The purpose is to provide equipment.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

In FIGS. 1 and 2, numeral 1 is a fish storage area for storing fish, and a small pond or an aquarium 1a as shown in the same figure is used. 2
is a forced circulation circuit, and in the illustrated example, it includes a suction pipe 4 having a suction part 3 that sucks water from a relatively deep part of the water storage part 1, a filtration device 5 connected to this suction pipe 4, and a connecting pipe. 6, a pump 7, and a discharge pipe 8 that is connected to the discharge port of the pump 7 and sends water to the water storage section 1 again.

This filtration device 5 has a porous ceramic filtration member 10 in a container body 9. In addition, the discharge pipe 8 of the forced circulation circuit 2
A discharge part 11 at the tip of is opened inside the fish farming water storage part 1,
A jet stream J is vigorously ejected in a substantially horizontal direction. That is, it is preferable that the pump 7 be a line pump such as a cant pump, which can produce particularly strong water flow 6 or at a flow velocity close to that of a mountain stream.

Furthermore, the air suction pipe 12 is installed upright on the discharge part 11,
It projects upwards from the water surface W. Since the flow velocity of this discharge part 11 is high, the static pressure of the discharge part 11 becomes negative pressure,
Inhale air from the atmosphere as shown by arrow B. Therefore, along with the jet stream, a large number of bubbles E are ejected into the fish culture storage section 1.

Further, a porous ceramic 13 is attached to the upper end of the air suction pipe 12 in the form of a capsule as shown in FIGS. 1 and 9.

For example, a porous ceramic fired from about 50% quartzite and about 50% Ena stone is used. The particle size is extremely fine, preferably about 1 m/m mesh. This porous ceramic 13 prevents the entry of fallen bacteria such as E. coli and prevents water damage.

In addition, in the illustrated example, the filtration device 10.10 and the suction pipe 4.4 are 2
Each piece is merged at a part of the connecting pipe 6. Furthermore, you are free to increase or decrease this number.
It is determined by considering the balance between the suction resistance and capacity of the filtration device 5 and the sizes of the pump 7 and the water storage section 1, etc.

FIG. 5 shows a detailed example of this filtration device 5, in which the porous ceramic filtration member 10 is a cylindrical column 14, which is made of a special ceramic material. That is, it is made by crushing a variety of Ena stone, making it into a cylindrical shape, and firing it into a porous state, which has natural magnetism and emits alpha rays. Water flows in the direction of the arrow, that is, from the outer circumferential surface to the inner diameter direction, and is filtered. In the case of goldfish and crucian carp, this cylinder post 14
A porous ceramic filtration member 10 made entirely of the following materials can be used satisfactorily.

Next, FIG. 6 shows another specific example of the filtration device 5, in which the cylindrical column 14 described in FIG. 50~
A 70 mesh ceramic filter 15 is fitted onto the outside. This filter 15 has the function of physically adsorbing fine particles and smoothing the water.

On the outer periphery of this ceramic ivy filter 15, a fence-like ceramic cylinder 16 of about 10 to 20 meshes made by crushing quartz porphyry and firing it into a cylindrical shape is fitted.

Since water flows from the outer circumferential surface of the ceramic cylinder 16 toward the inner diameter as shown by the arrow, large inorganic substances and dust are disposed of (chemical adsorption and decomposition) by the outermost ceramic cylinder 16. Moreover, this ceramic cylinder 16 also serves to remove odor from the water and to elute minerals.

Next, the filtration device 5 shown in FIG. 7 has the same structure as that shown in FIG. 6, and a cylindrical plastic sponge filter 17 is fitted onto the outside to remove large dirt and feces. That is, water flows as shown by the arrow, and from the outside to the inside, the plastic sponge filter 17,
Fence-shaped ceramic cylinder 16, ceramic filter 1
It has a multilayer structure in which a cylinder 5 and a cylindrical column 14 are combined.

In addition, in FIG. 6 or FIG. 7, it is also preferable to provide a stainless steel filter of 40 to 70 meshes between the ceramic cylindrical column 14 and the ceramic filter 15.

By interposing this stainless steel filter, filtration can be made more efficient, and the cylindrical column 14 can be prevented from being contaminated, so that the usage period can be extended.

As shown in FIG. 1, activated stones 18 are placed at the bottom of the fish farming water storage section 1. The activated stone 18 is a mixture of feldspar of the quartz porphyry family, a variety of Ena stone, and chlorite. Feldspar of the quartz porphyry family elutes minerals, and varieties of Ena stone have natural magnetism and α
In addition to giving off lines and making the water mellow, chlorite has trace magnetism and elutes multi-element minerals. In this way, by harmoniously mixing the multi-element raw stone and the magnetic raw stone and submerging it at the bottom of the water, there is a great advantage that the water can be activated, spoilage can be prevented, and fish odor can be deodorized.

Next, FIGS. 3 and 4 show another embodiment. FIGS. 3 and 4 correspond to FIGS. 1 and 2, respectively, and since the same reference numerals indicate the same structure, the explanation will be omitted, but the differences are as follows.

That is, a special activated stone tank 19 is interposed in the middle of the discharge pipe 8. A detailed example is shown in FIG. 8, in which activated stones 18 are housed inside the tank body 20, and water flows through them as shown by the arrow. This activated stone 18 was sunk to the bottom of the water in Figure 1, and is therefore a feldspar of the quartz porphyry family.
Mixed with chlorite, a variety of Ena stone, the elution of multi-element minerals, magnetism, and α-ray radiation activate water, prevent rot, and deodorize fishy odors, making it great for keeping water clean at all times. act.

Therefore, in FIG. 9, the jet stream J is ejected from the discharge part 11 of the forced circulation circuit, and
This shows the state when clean air is sucked in from the air suction pipe 12 by utilizing the negative pressure (static pressure) of the air and is ejected into the water storage part 1 as bubbles E. By appropriately selecting the capacity and performance of the pump 7, a sufficiently powerful jet stream J can be obtained, and bubbles E are sucked into the discharge section 11 to generate cavitation.

This naturally generates ultrasonic waves, which also have a sterilizing effect. Furthermore, if the water becomes contaminated with fish food and droppings, the viscosity of the water will increase, causing air bubbles E to form on the water surface W.
It floats to the top as bubbles F...

This floating pond F adsorbs putrefactive components and dirty components in the water, so if this foam F is scooped out by hand or with the ceramic net 22, the putrefactive components and various germs in the water can be completely removed. That will happen.

- In particular, waves are generated on the water surface W by the jet flow J in the approximately horizontal direction, and the waves flow toward the corner 21 of the water storage section 1, floating pond F...
are gathered together. Therefore, the above-mentioned bubbles F... can be easily removed.

Although not shown in the drawings, it is also desirable to interpose a water temperature regulating device, such as a cooling device using a heat pump, in the middle of the forced circulation circuit 2.

In addition to the aquarium 1a, the fish farming water storage section 1 may be a pond or the like.

〔Effect of the invention〕

Since the present invention is configured as described above, it has the following significant effects.

■ Active porous ceramic filtration member 10 with magnetism
This powerfully purifies water.

■ The clean air filtered together with the jet stream J creates air bubbles E.
It also has a bactericidal effect due to cavitation, and can effectively prevent the proliferation of bacteria in the water.Furthermore, it is easy to remove putrefactive components and bacteria in the water as a floating pond F.

■ A situation similar to a mountain stream can be obtained.

That is, the speed of the water flow due to the jet stream J and the state in which the clean air forms bubbles E and mixes into the water are obtained.

■ Due to the synergistic effects of the above ■ to ■, we were also able to successfully raise acanthus, char, sweetfish, etc.
