2. Description of the Related Art In Japan, due to its geographical features and weather characteristics,
The rainwater that is brought in throughout the year forms numerous rivers that do not deplete the mountainous areas that are rich in nature as natural dams, and has poured into the sea on all sides since ancient times. In this way, Japan is blessed with many rivers and surrounded by the sea. Naturally, fisheries that rely on and utilize the rich marine resources that come from them have been established since ancient times. However, at one time, it constituted an industry that enriched the national population. However, due to changes in various factors and restrictions over time, the fishing industry that relied on natural resources was forced to decline,
The self-sufficiency system up to that point has collapsed, and it has already been a long time since the transition to an era in which most of the natural seafood also had to depend on foreign countries.

Despite such supply circumstances, there is a strong preference for marine products due to the traditional Japanese culture of Japan, and in particular, a change in preference reflecting the abundant lifestyle such as the recent trend toward gourmet food. And from the policy intention to stabilize the fishery as a commercial enterprise, Japan's fishery will be transformed into a cultivated fishery, that is, aquaculture, and the marine products imported from other countries will be combined with the stable fishery products unique to Japan. It is being supplied. Looking at the share of the aquaculture industry in the output of fisheries in Japan, it has reached 30% or more for marine aquaculture and 80% for inland aquaculture.

The fishery resources targeted for maintaining the aquaculture industry as a stable industry are naturally high-class fish with high production efficiency, but all high-class fish can be the target. Not surely, for example, "rock fish" that live in the deepest mountain stream in the mountains, for which culture technology has not yet been established, have so far been considered difficult to reliably farm, and high-class restaurants and geographically endowed regions The "rock fish" offered at the hot spring inns, etc. are just natural products cooked according to the catching situation, and even though they are temporary, at present, they are left to survive in the fish tanks for a specified period of time. It is said to be almost difficult to keep.

While being aware of the above-mentioned actual conditions of aquaculture technology, the present invention, while being engaged in this kind of industry for many years in a blessed geographical environment, has met expectations from the surroundings. As a result of listening and listening to requests, even if it is not possible to immediately reach complete aquaculture (i.e., aquaculture that manages the entire life history of the aquaculture target, such as carp, rainbow trout, red sea bream, and prawn prawns), for example, eels and sweetfish. , Yellowtail,
Repeatedly engaged in the development and research of "rock fish" aquaculture that can approach even a step closer to aquaculture that is carried out using natural seedlings such as oysters (culture that is said to be incomplete culture compared to the previous complete culture), and repeats As a result of repeated thought and error, we finally succeeded in realizing a new water tank with the configuration as detailed below and achieving the intended purpose.

The water tank of the present invention basically has the following structure. That is, the plane shape is substantially elliptical, and an aquarium body having an appropriate depth can be mounted and fixed on the upper opening of the aquarium body, and has an elliptical orbit along the outer periphery of the aquarium body with a predetermined width and depth. It is composed of a purifying flowing water groove forming a water channel, and a pump for pumping water from the water tank main body is incorporated in the purifying flowing water groove, and at least ½ or more of the total length of the purifying flowing water groove is provided downstream thereof. While laying and forming the filter layer over the range, while separating the purifying water groove by a plurality of weir plates at predetermined intervals, adjacent ones of these weir plates, one of which is a filter in the purifying water groove All of the upper heights except the layers were blocked, and the other was placed so as to be alternately arranged in the total height including the filter layer so as to block some of the upper portions, and were partitioned by the weir plates. Inside the purifying water ditch section, the filter layer The crushed zeolite particles are filled only in the compartment where the weir plate that is not cut off is located on the upstream side, and the pumped-up water in the purification water channel is forced to flow down alternately on the lower end side and the upper end side of the weir plate. Then, the water tank is configured to circulate through the water discharge hole provided at the end of the purifying water groove to the water tank body.

The main body of the aquarium is made of strong transparent glass or acrylic and has a substantially elliptical shape in plan view, that is, a main portion is a straight line having a predetermined width and a corner portion is a large arc shape. It is formed so that the change from the straight line of the shape becomes a very natural shape, and the water stored inside can realize a smooth flow in a predetermined direction, and at the same time, the "rock fish" itself of extremely timid and nervous nature. However, special care must be taken to prevent injury or weakness when hitting an unnatural and sudden swim, especially at the corners. In order to respond to these movements peculiar to Japan, the size of this aquarium body is the diameter of the arc-shaped parts at both ends (= depth of the aquarium body).
Is at least 45 cm and the overall width is at least 8
It is necessary to secure 0 cm or more, and at least 50 cm or more in depth.

[0008] The purifying flowing water groove is mounted on the upper opening portion of the water tank body in a mounted manner, and has a substantially elliptical shape in plan view as a whole. It consists of a waterway with an elliptical orbit of a predetermined width along the contour, and a pumping pump for drawing up the water stored in the aquarium body is installed at an arbitrary location, and then the following structure is provided downstream. Must be incorporated. First, after laying and forming a filter layer over a range of at least ½ or more of the entire length of the purification water channel, the purification water channels are separated by a plurality of weir plates at predetermined intervals, and the adjacent weir plates are separated from each other. In relation, one weir plate blocks the entire height above the filtering water channel except the filter layer, and the other weir plate blocks the upper part of the entire height including the filter layer and blocks it. It is arranged so that it becomes an alternating arrangement.

The arrangement relationship of the barrier plates can be shown by the following description. That is, with a height dimension smaller than the depth of the purifying flowing water groove by the filter layer thickness, a weir plate of a width dimension that can close the entire groove width of the purifying flowing water groove, with a predetermined interval, and adjacent ones, It can also be said that one of them is arranged in an alternating arrangement in which the upper end is aligned with the upper edge of the purifying water groove, and the other is arranged such that the lower end is in close contact with the bottom of the purifying water groove.

[0010] In the purifying water flow groove section divided by the weir plates, a weir plate that does not block the filter layer (in other words, the depth of the purifying water flow groove is equal to the filter layer thickness). A weir plate that has a small height and a width dimension that can close the entire width of the purification water flow groove, and the upper ends of the weir plates that are arranged at prescribed intervals are the upper edges of the purification water flow groove. The weir plate arranged in (1) is limited to the compartment located on the upstream side to fill the crushed zeolite particles. As a result, the pumped up water in the purifying water groove is forced to flow down alternately on the lower end side and the upper end side of the weir plate, and the end of the purifying water groove (completely separated from the pumping pump grounding point described above). It is designed to circulate in the main body of the water tank from the water discharge hole provided in the adjacent location). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments representative of the present invention shown in the drawings will be described to help understand the basic configuration of the present invention.

[0011]

Embodiment 1 FIG. 1 is a plan view of a water tank embodying the technical idea of the present invention. FIG. 2 is a front view showing a cross section of a part of the water tank, and FIG. 1A and 1B are enlarged vertical cross-sectional views of essential parts shown by unfolding the cross sections AA in FIG. As can be clearly understood from these drawings, the aquarium main body 1 is entirely formed of a tempered glass in a planer shape and has a substantially elliptical shape, and the inside can be seen through and the structure is suitable for a cage such as a restaurant. In the upper opening, a contour is formed substantially equal to the plane shape of the water tank body 1, and a predetermined width is placed inside the water tank body 1. As shown in the cross-sectional view of FIG. The purifying flowing water groove 2 is fitted and placed. In the figure, 21 is a fitting edge provided on the outer peripheral lower end of the purifying flowing water groove 2 for fitting with the water tank main body 1, and 22 is reinforcing the purifying flowing water groove 2 made of a stainless steel material. The rib which reinforces the upper opening part of the water tank main body 1 which is overloaded by water pressure is shown.

In the purifying flowing water groove 2 having a groove-shaped cross section, the pumping pump 6 is attached to the inside of the arcuate portion on one side (on the left side in the drawing) by the hook metal fitting 61, and the main body is stored in the water tank main body 1. The water suction pipe 62 is hung in the water, while the drain pipe 63 is connected to the pumping pump 6.
In the purifying water channel 2 on the downstream side. Further, a partition plate 7 is installed in the purification water flow groove 2 which is located at a position adjacent to the grounding point of the pumping pump 6 and is in a position opposite to the downward direction, and the purification water flow groove 2 is divided by the partition plate 7. The opposite side of the pumping pump 6 installation side (right side in the figure)
Is provided with a water discharge hole 8.

In this example, as shown in the plan view of FIG. 1, approximately two-thirds of the total length of the purifying water flow groove 2 reaching the water discharge hole 7 on the downstream side of the installation position of the pump 6 for the purifying water flow groove 2. The filter layer 3 is laid and formed on the bottom of the groove over a range of about a certain extent, and the height of the filter layer 3 is smaller than the depth of the purifying flowing water groove 2 by the thickness of the filter layer 3 in the arrangement orthogonal to the flowing water direction. Install the weir plates 5, 5, ... with the full width at appropriate intervals. In the combined structure of the filter layer 3 and the weir plates 5, 5, ..., In the arrangement relationship of the adjacent weir plates 5, 5, the lower end of one weir plate 5 is the filter layer 3
The barrier plate 5 should be arranged so that it reaches the bottom of the purifying flowing water groove 2, and the other dam plate 5 is arranged so that the lower end of the dam plate 5 stops on the upper surface of the filter layer 3. I have to.

The weir plate 5, which is regulated and arranged as described above,
5, the partition between the pumping pump 6 and the water discharge hole 7 of the purifying drainage channel 2 is divided into several sections, and a weir plate that does not block the filter layer 3 in these sections (in other words, As shown, the weir plates 5, 5, ... Formed to have a height dimension smaller than the depth of the purification water flow groove 2 by the thickness of the filter layer 3 and a width dimension capable of closing the entire width of the purification water flow groove 2. , The weir plates 5, 5, ... Arranged at predetermined intervals, the upper end of which is aligned with the upper edge of the purifying flowing water groove 2.
It is assumed that the crushed zeolite particles 4 are filled only in the section where 5, ... Are located on the upstream side. Therefore, in each section, at least every other section is filled with the crushed zeolite particles 4.

In the water tank body 1 shown as an example,
Although it is shown that nothing is put inside it except water W, it is also possible to place decorative stones, water plants, etc. on the bottom as needed. Depending on the purpose, for example, crushed zeolite particles may be spread for the purpose of preventing spoilage such as bait debris and feces that settle at the bottom. It is free to use different means together.

[0016]

[Operation] The water tank of the present invention obtained as described above is used to pump water W other than specially harmful water such as water stored in the water tank main body 1, well water or river water, ordinary tap water, etc. When the water W flows up through the purification water groove 2 and reaches the first weir plate 5 and is blocked, the weir plate 5 has an upper edge. In the case of the one aligned with that of the purifying flowing water groove 2, it penetrates into the filter layer 3 which is laid on the lower end side of the dam plate 5 and communicates with the adjacent compartment, and starts to flow into the adjacent compartment. By preliminarily adjusting the balance between the inflow resistance of the filter layer 3 and the pump-up capacity, the water W that is pumped up and flows out is blocked by the weir plate 5 and begins to accumulate, and overflows from the purification water flow groove 2. Do not let it go.

When the water W that has flowed into the adjacent compartment through the filter layer 3 on the lower end side of the weir plate 5 is attempted to further descend, the next weir plate, that is, the lower end thereof, abuts the bottom of the purifying water groove 2 this time. It starts to accumulate after being blocked by the weir plate 5, and then rises gradually, and continues to rise while passing through the partition filter layer 3 and passing through the gaps of the crushed zeolite particles 4 filled therein, and finally the lower end is a purifying water groove. 2 Ascend to the full height of the dam plate 5 that could not be crossed because it was in contact with the bottom. However, since the height of the dam plate 5 is regulated to be smaller than the depth of the purifying flowing water groove 2, there is a space between the upper end of the purifying flowing water groove 2 and the purifying water. It does not overflow from the water flow channel 2 and flows into the next section beyond the upper end of the dam plate 5.

This section is a section not filled with crushed zeolite particles 4 and has a filter layer 3 at the bottom of the purifying flowing water groove 2.
Since it is laid, only the first weir plate 5 in which the lower end of the weir plate 5 rides on the filter layer 3 reaches the next weir plate 5 while penetrating the filter layer 3 first. Since it is similar to the case of,
In a state similar to the case of the weir plate 5 that is pumped up and first encountered, a part of the filter layer 3 is blocked by the weir plate 5 and collects in the same compartment, while a part of the filter layer 3 leads from the lower end to the next compartment.
Through to the next compartment, and thereafter, while repeating the above-mentioned inflow state, finally migrates to the compartment having the water discharge hole 8.

The section in which the water discharge hole 8 is formed is located at a position adjacent to the grounding point of the pumping pump 6, and a partition plate 7 is installed in the purifying flowing water groove 2 between them to pass through each section. The water W that has come in does not flow into the pumping pump 6 installation side, and all flows back to the aquarium body 1 from the water discharge hole 8, thus completing the one-cycle purification process. This purification process is continuously repeated while pumping up, so that this flow also induces a flow in the water itself stored in the aquarium main body 1 and breeding therein. An extremely advantageous environment will be realized for fish that live, especially for mountain stream fish such as "rock fish".

[0020]

[Effects] As described above, the water W pumped up is regulated while flowing down once through the purifying water channel 2 divided by the dam plates 5, 5 ,. Due to the weir plates 5, 5, ... Arranged, the water flows downward with a large swell, and various impurities contained in the water W are agitated in the movement. In the process of passing through each compartment, the impurities are extremely efficiently filtered and adsorbed when passing through the filter layer 3 which is regulated in each compartment, or the filter layer 3 and the zeolite granules 4. At the same time, since the water W itself can be brought into contact with air in a stirring state to take in more air oxygen, the water W that finally circulates from the water discharge hole 8 to the water tank body 1 is almost Extremely high water, purified to near-ideal water quality It can be sufficiently adapted to breeding mountain stream fish that require quality.

As described above, the water tank is capable of always ensuring the high quality water W through the purifying mechanism having a very advantageous characteristic for water purification, and the water tank body 1 is substantially elliptical and has an appropriate depth. Since it is formed into a deep water, it is pumped up from the pumping pump 6, and then the water discharge hole 8 is formed while swelling up and down in the purifying flowing water groove 2 having a water channel of an elliptical orbit along the outer periphery of the water tank body 1. After that, it recirculates, and pumping pump 6 again
Water W to which kinetic energy has been added by the downward motion of the water
The movement of the fish can be carried over to the aquarium body 1 as it is, and an environment with a flow like a river in the aquarium body 1 can be easily realized. Especially, an environment close to nature such as "rock fish". It is an aquarium that is ideal for breeding fish that need fish.

As described above, the aquarium of the present invention has a very rational purification mechanism incorporated therein, and is particularly excellent in that it enables breeding of mountain stream fish sensitive to water quality without any trouble. It is characterized by the fact that in the era when more and more genuine food and rare foods such as high-grade fish are demanded from the viewpoint of table culture in view of the margin of living, it will be highly evaluated as one of the devices that immediately responds to the times. is expected.
