1, the farm in accordance with the present embodiment may include a cylindrical body 100, a temperature control unit 200, and a super air lift apparatus 300. As shown in FIG.

As shown in the figure, the cylindrical body 100 may be provided in a concave funnel shape on the floor surface, and the aquaculture water W1 may be accommodated therein. A first port 110 may be provided at the center of the bottom surface of the cylindrical body 100, and a second port 120 may be provided at an upper surface of the side wall.

The bioflare aquaculture water W1 contained in the cylindrical body 100 is rotated clockwise or counterclockwise by the super air lifter 300 so that foreign matter such as excretion contained in the aqua water W1 It can be decomposed by microorganisms.

The foreign matter such as excretion produced by the fish cultured in the aquaculture water W1 may be discharged to the outside through the first port 110 formed at the center of the cylindrical body 100. At this time, The first port 110 is provided with a grill member 111 to prevent the fish being fed through the first port 110 from flowing into the circulation pipe 130. The grill member 111 is not necessarily required and can be omitted, and the shape of the grill member 111 can also be varied. 1, the grill member 111 may have a plurality of through holes protruding upward from the first port 110. Although not shown, the grill member 111 may be formed in a manner that covers the inlet of the first port 110 Can be configured.

An air lift device 140 for circulation is installed in the circulation pipe 130 so that air is supplied to the aquaculture water W1 through the first port 110, Through the port 120 to the cylindrical body 100 side. The circulating air lift apparatus 140 may be configured by arranging at least one air supply device such as at least one air stone inside a pipe.

In particular, the circulating air lift apparatus 140 may be installed before the valve apparatus 160, but not limited thereto, and may be installed in the flow path after the valve apparatus 160. [

When the center of the cylindrical body 100 is concave, the foreign substance such as excretion accumulates toward the center of the cylindrical body 100, so that the foreign substance flows into the first port 110 Through the circulation pipe 130 and the second port 120 to the upper side of the aquaculture water W1. When foreign substances such as excretion are circulated through the first and second ports 110 and 120, accumulation on the bottom surface of the cylindrical body 100 can be prevented, and thus, decay can be prevented.

The temperature control unit 200 may be installed on the bottom surface side of the cylindrical body 100. The temperature control unit 200 is for controlling the temperature of the aquaculture water W1 and can adjust the temperature of the water for cooling water W2 according to the type of fish to be cultured and the surrounding environment. For example, the cooling water W2 at a temperature higher than the aquaculture water W1 can be used for culturing the temperate fish. On the contrary, the cooling water W2 at a temperature lower than the aquaculture water W1 is used for culturing the cold- Can be used. In addition, the temperature of the cooling water W2 may be adjusted according to the surrounding environment and the temperature of the farm. That is, it may be used to maintain the temperature of the aquaculture water W1 constant in response to seasonal changes.

It is also possible to move hot air or cold air in place of the cooling water W2 in the temperature control unit 200 or adjust the temperature by using a specific refrigerant.

The cooling water W2 passing through the temperature control unit 200 can be controlled by using a heating unit such as a boiler, but is not limited thereto. That is, the cooling water W2 may be heated using solar heat (sunlight), or may be subjected to heat exchange with waste heat discharged from a steel mill, a heat-combined power plant, a waste incineration plant, .

The temperature control unit 200 may include a chamber 210, an input port 220 and an exhaust port 230.

The chamber 210 may be formed in a shape corresponding to the bottom surface of the cylindrical body 100. The cylindrical body 100 and the chamber 210 may be formed of materials that can be easily exchanged with each other. have. For example, the bottom surface of the cylindrical body 100 may be formed of a metal material, and a chamber 210 through which the cooling water W2 moves may be formed below the bottom surface.

The input port 220 and the exhaust port 230 are formed at both ends of the chamber 210 at least one through hole to supply and discharge the cooling water W1 to the inside of the chamber 210. [ At this time, the sizes of the input port 220 and the discharge port 230 may be set to correspond to each other, so that the flow rate of the cooling water W1 may be maintained constant.

8, a load of the cylindrical body 100 can be supported by the honeycomb-shaped reinforcing member 240 of the chamber 210. [ The reinforcing member 240 may disperse the load of the cylindrical body 100 applied in the gravity direction to maintain the space of the chamber 210 constant.

9, a plurality of through holes 241 may be formed in the reinforcing member 240 to allow the cooling water W2 to flow in and out through the through holes 241 . At this time, the through holes 241 may be formed to have a predetermined size, but the through holes 241 may be formed to have different sizes as needed.

As another example, a labyrinth-shaped reinforcing member 250 may be installed inside the chamber 210 as shown in FIG. 9, the end of the reinforcing member 250 may be spaced apart from the inner space of the chamber 210 by a predetermined distance so as to allow water to flow therethrough, thereby forming a zigzag flow path capable of flowing water. .

The reinforcing members 240 and 250 may be formed in various shapes other than the honeycomb or maze shape. Although not shown, a plurality of cylindrical or hexahedral supporting columns may be disposed at regular intervals, The plate-

1 illustrates a configuration in which the chamber 210 is disposed on the bottom surface of the cylindrical body 100. However, the present invention is not limited thereto and may be formed around the cylindrical body 100 as well.

The super air lift apparatus 300 may include a first body 310, a second body 320, a fresh water discharge port 330, and a flow rate control unit 340.

The first body 310 may have a substantially rectangular parallelepiped shape and may have a width larger than a height. The upper surface of the first body 310 is arranged to correspond to the water surface of the aquaculture water W1, the second body 320 is connected to the lower side, and the aquaculture water discharge port 330 is connected to the front side . The width of the first body 310 may be increased or decreased according to the diameter of the cylindrical body 100. The width of the first body 310 may be set so that the width of the first body 310 does not exceed 50% can do.

The second body 320 may be bent at a predetermined angle alpha with respect to the first body 310 and may have a width corresponding to the first body 310. An opening 321 is formed at an end of the second body 320 so that the aquaculture water W1 can be introduced into the first and second bodies 310 and 320 through the opening 321. [ 2 and 3, the second body 320 may be formed as one body with the first body 310, and the second body 320 may be formed as a body having a predetermined angle? The reason for configuring the air supply device 350 is that the installation space of the air supply device 350 is more easily secured and the lengths of the first and second bodies 310 and 320 are made as long as possible to ensure a long flow path . When the flow path is long, the oxygen-containing air supplied through the air supply device 350, which will be described later, can be mixed with the aquaculture water as much as possible and the flow velocity can be increased.

3, the opening 321 is formed to be perpendicular to an end of the second body so that the air injected through the air supply device 350 is directed to the second body (Not shown). When the inner surface of the second body 320 is disposed to face the upper side of the air supplying device 350 as described above, the air injected from the air supplying device 350 does not leak to the outside of the second body, Can be discharged only toward the discharge port 330 formed in the intended direction in the flow path formed by the first and second bodies 310 and 320.

As shown in FIG. 3 and FIG. 4, a plurality of air supply devices 350 may be disposed at regular intervals in the second body 320. The air supply device 350 is a well-known air supply device such as an air stone. The air supply device 350 receives air containing oxygen through the tube 351, Air can be supplied. The openings 321 may be larger than the aquaculture water discharge port 330 to be described later so that a maximum amount of the aquaculture water W1 can be smoothly supplied to the air supply device 350.

3 and 4, a plurality of air supply devices 350 may be disposed in the width direction of the second body 320, and each of the air supply devices 350 And may be connected to a distribution pipe 352 connected to a tube through which oxygen-containing air is supplied. As described above, if the air supply device 350 is disposed in the width direction of the second body 320, air having a larger amount of oxygen can be supplied to the second body 320 due to an increase in the length of the air supply device such as an air stone It can be supplied in water. In addition, it is possible to form a strong flow rate compared to the conventional air lift due to the air pressure generated by supplying a large amount of air at a time.

Meanwhile, it is also possible to cause fish to be caught in the air between the air supply units 350. In this embodiment, in order to prevent the fish from flowing into the air supply units 350, (353). The fish screening unit 353 is a box-shaped cover composed of mesh members in the form of a mesh, and may be provided with a frame to form a frame, or may be provided with a box-shaped mesh member made of a plastic material Do.

The size of the through holes of the mesh members constituting the fish screening unit 353 may vary depending on the type and size of cultured fish. If the mesh size of the mesh member is set to be too small, the flow of oxygen containing air supplied through the air supply device 350 may be blocked to slow down the flow velocity. Therefore, It is better to form smaller fish than the fish being cultured.

The aquaculture water discharge port 330 may be disposed at a position corresponding to the water surface of the cylindrical body 100 protruding in the vertical direction integrally with the first body 310 and forming the aquaculture water tank. As shown in FIG. 2, the aquaculture water discharge port 330 has a width corresponding to the width of the first body 310, so that the greatest amount of water is discharged through the aquaculture water discharge port 330 . The aquaculture water W1 discharged through the aquaculture water discharge port 330 can form a flow rate in the aquaculture water W1 by using the pressure formed by the air containing oxygen through the air supply device 350 have.

4, since a plurality of air supply devices 350 are installed in the second body 320 in the width direction, the air supplied to the air supply device 350 The flow of the aquaculture water W1 can be formed by the supply pressure, which is very strong compared to the flow rate generated by the conventional air lift apparatus. Therefore, when such a strong flow rate is applied to aquaculture water (W1) stored in the aquaculture tank, it is necessary to reduce the speed so that the flow rate is appropriate for aquaculture, since the flow rate is so strong that the fish is unsuitable for living.

The flow rate control unit 340 is provided to reduce the flow rate of the aquaculture water W1 discharged from the aquaculture water discharge port 330 when the flow rate of the aquaculture water W1 is excessively fast. (d).

At this time, the through holes may be formed to have the same diameter, or the through holes of different diameters may be irregularly formed as shown in the figure. When the through hole is formed as described above, the flow velocity is controlled by the water discharged through the through holes, and the load applied to the flow rate blocking plate 342 may be reduced. 2 (a), the load applied to the support member 341 may become excessively large. However, when the through hole is formed as shown in FIG. 2 (b), the through hole This is because the load of the water flow rate can be reduced.

Both ends of the flow rate blocking plate 342 may be connected to the support member 341 and disposed in a direction perpendicular to the discharge direction of the aquaculture water W1. In addition, the flow rate cutoff plate 342 can be moved in the vertical direction A with reference to the water surface as shown in FIG. 3, so that the discharge rate of the aquaculture water W1 can be adjusted. For example, when the flow rate of the aquaculture water W1 needs to be reduced, it is arranged at a height corresponding to the water surface as shown in Fig. 5, and when the flow velocity is to be increased, The aquaculture water W1 can be discharged with the flow rate generated by the air containing oxygen being maintained above the plate 342. [

The second support 420 may be thicker than the first support 410, 1 support 410 may be configured to be adjustable in length as it moves up and down in the inner space of the second support 420. At this time, the fixing of the first and second supports 410 and 420 can be fixed using a fixing pin 421 or the like.

Meanwhile, as described above, the first and second support rods 410 and 420 are merely examples, and any structure can be applied as long as the length is changeable.

On the other hand, a rubber or silicon non-slip member 430 may be installed on the bottom surface of the second support base 420 so as not to slip on the bottom surface of the circular body 100.

In addition, the super air lift apparatus 300 configured as described above may be provided with a fixed unit 500 so as to maintain a fixed state on the bottom surface of the cylindrical body 100.

The fixed unit 500 includes a plurality of weights 510 mounted on the upper surface of the first body 310 and a cover 520 covering the weight 510.

The weight 510 may be a building material such as a generally used brick or the like, or it may be a stone that can be easily obtained from the surroundings. The weight 510 pushes the super air lift apparatus 300 constructed as described above to the weight so as to maintain the support 400 in close contact with the bottom surface of the cylindrical body 100.

The cover 520 is provided to correspond to the shape of the upper surface of the first body 310 to prevent the weight 510 from being exposed to the outside.
