(Effects of the Invention)

According to the present invention, the following effects are exhibited.

In the invention described in the above (1), a section of a purification section in which a purification device is provided is formed in the front part of a fish tank divided right and left by a partition wall, and at the bottom of the rear section of the partition wall in the second fish tank. Since a large number of settling boxes are arranged in a wide range, large fish dung or residual bait that mixes and flows into the breeding water of the fish tank settles in the settling box and arranges an airflow device that causes the minimum water level to rise, thereby raising the water to the breeding water. Since it generates a flat water flow, power energy can be minimized.

In addition, when the air flow device is compressed air discharged from the bottom of the groove hole formed in the bottom of the fish tank to the breeding water by air pipes as air bubbles in the front part of the barrier wall and rises, the water surface of the breeding water directly above the air bubbles increases. As the water level rises, a flat tide-like water flow occurs, and the breeding water can be used as circulating water to circulate the entire fish tank with little power.

Oxygen in the air, which has been bubbled in the breeding water, can be dissolved in the breeding water to increase the oxygen concentration in the breeding water. In addition, since it is also possible to remove the vaporized carbon dioxide on the water surface, the apparatus for removing carbon dioxide can be omitted.

In the invention described in (2) above, since a plurality of sedimentation boxes are arranged on the bottom surface of the rear portion of the blocking network in the front portion of the second aquaculture tank, a plurality of sedimentation boxes are arranged in the second aquaculture tank. It is possible to recover and lighten the burden of the purification device in the purification unit.

In the invention described in the above (3), in the purification unit for arranging the purification device between the second and first water tanks, the water channel is branched and installed to reflux the breeding water to the fish tank via the purification device. Purification devices can be placed in remote locations. Further, it is possible to facilitate cleaning of the purification device by closing the water passage to the purification section.

At the rear portion of the second fish tank 2B, there is an airflow device 3 that ejects air bubbles 8 from below in the middle of the front and rear shut-off networks 3E, 3D so as to make the water rise immediately above and generate a flow. The width of the 2nd fish tank 2B is arrange|positioned full.

A plurality of sedimentation boxes 4A and 4A are provided in parallel in the width of the second fish tank 2B at the rear portion of the rear portion blocking network 3D. The purification section 4F is partitioned with the front and rear portions of the first fish tank 2A and the blocking nets 3E and 9 arranged in parallel in the front section of the second fish tank 2B.

When the airflow device 3 is operated, the breeding water is full of a flat water flow in the second fish tank 2B, and the flowing water is purified from the second fish tank 2B to the purifying unit 4F ( After passing through 4), the first fish tank 2A enters and the entire fish tank 2B is further circulated.

The number of breeding is, for example, about 150 cm in depth, but it is adjusted according to the size and quantity of fish.

The fish farming apparatus 1 shown in FIG. 1 has, for example, a length of 55 m and a width of 11 m, and the first and second fish tanks 2A and 2B parallel to the left and right are partition walls 5. It is divided into.

A part of the partition wall 5 protrudes from the purification section 4F to contact the wall surface of the purification device 4, and a recovery path 5A having an opening/closing door 5B that can be opened and closed is formed on the part, thereby purifying It is possible to circulate the livestock that does not pass through the device 4.

The purification apparatus 4 in the purification part 4F of about 17 m in length is arrange|positioned so that it may be sandwiched between the 1st fish tank 2A and the 2nd fish tank 2B.

The airflow device 3 is elongated in the width direction of the second fish tank 2B at the front end of the bottom of the second fish tank 2B, as in the longitudinal section II-II in FIG. 1 shown in FIG. For example, a deep groove hole 3A exceeding 2 m is formed, and the barrier wall 3B blocking the water before and after the groove hole 3A is interposed between the water surface and the bottom of the groove hole 3A. It is arranged, and is divided into a plurality of partition walls 3C (5 sections in Fig. 1) in the width direction of the second fish tank 2B, whereby water flow is efficiently generated. The partition wall 3C need not be formed unless necessary.

As a result, as shown in Fig. 2, the number of animals raised in the first fish tank 2A enters the long groove hole 3A in the width direction of the second fish tank 2B, exits under the blocking wall 3B, and passes through the groove hole. It goes above the front part of (3A) and enters the second fish tank (2B).

As shown in Fig. 2, a pair of front and rear blocking networks (3D, 3E) regulating the traffic of the fish are provided at the bottom (2C) of the first and second fish tanks (2A, 2B), which are the upper and lower edges of the front and rear edges of the groove hole (3A). It is installed up to the water.

As shown in Figs. 1 and 2, in front of the lower edge of the blocking wall 3B of the groove hole 3A, a gas pipe 7 extending from the air-blowing device 6 is disposed, and a gas opening upwards at the upper portion The discharge port 7A is formed. The gas discharge port 7A may have any number or shape as long as the bubble 8 comes out.

When compressed air is sent from the air blower 6, the air bubbles 8 rise vigorously from the gas outlet 7A, so that they rise directly above the breeder.

The raised breeding water moves horizontally like a tsunami in front of the second fish tank 2B to generate a water flow, and enters the first fish tank 2A through the purification device 4 in the purification section 4F. It is circulated throughout the second fish tank 2B.

As a result, as the number of livestock flowing through the upper part of the sedimentation box 4A, the heavy ones such as residual bait and fish dung are precipitated and removed from the sedimentation box 4A, and ammonia, organic matter, and sedimentation in the next biofilm processing device 4D. The fine particles that have passed through the box 4A are filtered, and the circulation of the breeding water can be filtered with high efficiency even if, for example, 200 m 3 /hour. By cleaning the opening and closing doors 2F and 2F, cleaning of the purification device 4 can be facilitated.

In the biofilm processing apparatus 4D, a filter network (not shown) is installed at the bottom of the fish tank 2, and a number of micro-fiber filters (not shown) are filled thereon, and air bubbles from the bottom are provided between each filter medium. Quilting and rising. Bacteria propagate and decompose, such as residual bait and fish dung attached to the filter medium. The filtered breeding water is refluxed from the bottom of the fish tank 2 to the first fish tank 2A through a circuit toward the top.

From the clean water supply pump 10 shown in Fig. 1, clean water is supplied to the first fish tank 2A through the clean water pipe 10A. As a result, the rearing density of fish and shellfish can be raised up to 100 kg per ton of water, for example.

In addition, when the oxygen concentration sensor 12 detects that the oxygen content in the water has reached an oxygen saturation level of 90% or less, the automatic controller 13 automatically operates the valve 11B of the oxygen tank 11 to operate the oxygen pipe 11A. ) Is supplied to the rearing water of the fish tank 2 to be saturated with oxygen.

In this case, it is possible to connect the oxygen pipe 11A to the transmission pipe 7 to be discharged to the breeding water together with the air bubbles 8.

For natural disasters and other emergencies, this oxygen supply is important.
