Description

AQUACULTURE CAGE HAVING APPARATUS FOR GENERATING NANOBUBBLE [0002]

The present invention relates to a farm including an ultrahigh-strength bio-cell generation apparatus, and more particularly, to a micro-centrifuge bio-cell production system comprising a micro-centrifuge cell production apparatus including a primary porous plate and a plurality of secondary porous plates, Which is capable of providing oxygen and providing a clean aquaculture environment.

In recent years, there has been an active transition from fisheries to fisheries, which are catching fisheries, and the fisheries aquaculture business contributes to the development of local economy and fisheries.

However, since the amount of dissolved oxygen in the water is limited, it is necessary to continuously supply the aquaculture water, and a floating matter including the excrement of the remaining feed and the fish by the input feed is generated, Lt; / RTI >

As an alternative to overcome the limitations of the method of preparing aquaculture tank, Korean Patent Laid-Open Publication No. 2014-0143245 discloses an invention, but the invention merely functions to circulate the aquaculture water to supply oxygen, There is no function to purify water.

Therefore, there is a need to apply ultra-fine oxygenated water having both an oxygen supply function, a floatation of water suspended in water to the water surface, and a water purifying function to the farm. When the ultrahigh pressure centrifugal force is extinguished by the self-pressurizing effect, free radicals such as a hydroxy radical can be generated to sterilize the water. Since the surface of the super strength centrifugal force is negatively charged and has a long residence time in water, The rate of reduction of the oxygen content is very small, and even invisible microscopic particles float on the surface of the water, helping to keep the water always clean.

In addition, since the amount of dissolved oxygen in a suitable culture water is different for each aquaculture product, oxygen bubbles having micro-sized or larger particle size are not dissolved in water for a long time and are quickly released to the outside, It is very difficult to control the amount of dissolved oxygen constantly. However, since the ultra-fine oxygen having a nano-sized particle size can not easily be released to the outside even if it is dissolved in water, it is possible to easily adjust the dissolved oxygen amount in the aquaculture water, It is easy to use, and it is possible to cultivate healthier blood culture objects by using ultra-fine oxygen.

The water tank 200 includes a bottom plate 210 formed on the ground and side walls 220 formed in a wall shape from a rim of the bottom plate 210.

The first line 300 and the second line 400 may be arranged in accordance with the size and shape of the water tank 200, the shape of the space in which the water tank 200 is installed, the arrangement of the water tank 200 and the ultra- A straight line or a curved line, or a straight line and a curved line.

Referring to FIGS. 2 and 3, the ultrasensitive capsule producing apparatus 100 of the present invention includes:

A supply line 130 connected to the chamber 150 and the first line 300 and the oxygen supply line 132 and a second supply line 130 located at an upper portion of the interior of the chamber 150 and spaced apart from the discharge port 133 of the supply line 130 A primary perforated plate 110 for passing the oxygen-forming water mixed stream injected through the supply pipe 130 to thereby miniaturize the oxygen contained in the oxygen-forming water mixed flow, , A plurality of spaced apart from each other in the lower space of the primary perforated plate 110 and allowing the oxygen-forming water mixed flow passing through the primary perforated plate to pass through again, thereby further refining oxygen in the oxygen- A secondary sieve plate 120 which forms a vortex to generate ultra-fine oxygenated water, and an outlet 140 connected to the second line 400.

The chamber 150 is configured to form the basic shape of the ultra-high strength liquid containing apparatus of the present invention and includes a supply pipe 130, a primary perforated plate 110, a secondary perforated plate 120, and a discharge port 140 . The shape of the chamber 150 is a cylindrical shape in an embodiment of the present invention. However, the shape of the chamber 150 is not limited thereto, and may be a rectangular parallelepiped shape, a triangular-column shape, or a spherical shape suitable for a place where the ultra- Or the like. In addition, the size of the chamber 150 may be 0.2-3 meters in height and 0.05-200 meters in bottom diameter based on the cylindrical shape. However, the size of the chamber 150 can be appropriately changed depending on the desired amount of ultrafast oxygenated water and the amount of dissolved oxygen generated.

2 and 3, oxygen is supplied from the oxygen supply pipe 132, water from the first line 300 is supplied to the inside of the supply pipe 130, As shown in FIG. 2, the jet port 133 of the supply pipe 130 is disposed at the lower portion of the primary perforated plate 110 so as to be directed upward As shown in FIG. 3, the outlet 133 of the supply pipe 130 may be disposed at an upper portion of the primary perforated plate 110 and may be disposed in a downward direction.

Since the amount of dissolved oxygen differs for each individual aquaculture, it is necessary to adjust the amount of dissolved oxygen. Therefore, a machine for measuring the dissolved oxygen amount can be mounted on the farm according to the present invention, and the dissolved oxygen amount measuring machine is mounted on each part of the oxygen supply pipe 132 and the first line 300 connected to the supply pipe 130 And a valve for opening and closing is determined according to the value of the dissolved oxygen amount measuring machine.

2, when the jet port 133 is located at the lower portion of the primary perforated plate 110 and faces upward, when the oxygen-form water mixture flows up, Through the first primary perforated plate 110, so that the amount of ultrahigh strength foaming can be increased more than when it is arranged in the form of FIG.

3, it is preferable that the inlet of the discharge port 133 of the supply pipe 130 is widened so that the oxygen-forming water mixture flows evenly through the primary perforated plate 110 But are not limited thereto.

The arrangement of the supply pipe 130 is not limited to the above-described mode, and when the oxygen-containing water mixed flow is sprayed from the supply pipe 130, it is preferable that all the forms capable of passing through the primary perforated plate 110 first .

The arrangement of the oxygen supply pipe 132 and the first line 300 for supplying the aquaculture water into the chamber 150 is not limited to this but is connected to the supply pipe 30 as shown in Figs. Or the oxygen and the culture water may be separately supplied to the supply pipe 130 or the first line 300 may be mixed with the oxygen supply pipe 132 or the oxygen supply pipe 132 may be mixed with the first line 300 And the oxygen-forming water mixed stream itself is supplied to the supply pipe 130. The oxygen-

The supply pressure of the oxygen-forming water mixed stream ejected from the supply pipe 130 is such that the oxygen-forming water mixed stream is primary even though the primary perforated plate 110 is not damaged by the oxygen- The pressure can be adjusted by controlling the length of the supply pipe 130 and the length of the discharge port 133 of the supply pipe 130 and the length of the first perforated plate 110 And the like.

FIG. 4 is a cross-sectional view of another embodiment in which the super-fine strength cell generating apparatus 100 of FIG. 2 is connected in series, and FIG. 5 is a cross-sectional view of still another embodiment to be.

Referring to FIGs. 4 and 5, a plurality of ultrasensitive capsule producing devices 100 according to the present invention may be connected in series. The plurality of ultrahigh-strength foam generating apparatuses 100 are connected in series through the connection line 160 and the connection line 160 may be provided with a pump 161 capable of applying pressure to the oxygen- , It is not necessary. When a plurality of ultrasound-pattern forming apparatuses 100 according to the present invention are connected in series, the concentration of ultrastable oxygen in the aquaculture water can be further increased.

FIG. 6 is a front view of the primary perforated plate 110 provided in the embodiment shown in FIGS.

The primary perforated plate 110 shown in FIG. 6 is a substrate through which the oxygen-forming water mixed stream ejected from the supply pipe 130 is firstly passed, and is very important for generation of ultra-fine strength. The primary perforated plate 110 primarily serves to refine the oxygen contained in the mixed flow and increases the contact area with oxygen by refining the culture water to increase the concentration of the finer oxygen in the mixed flow. Although the shape of the primary perforated plate 10 is not limited thereto, it may be circular as shown in FIG. 6, and may be implemented in various forms according to the shape of the chamber 50.

As shown in FIGS. 2 and 3, the primary perforated plate 110 may be installed to be spaced apart from the outlet 133 of the supply pipe 130, or may be mounted on the outlet 133 of the supply pipe 130 .

The primary perforated plate 110 may have a portion that does not contact the inner wall of the chamber because the sectional area of the primary perforated plate 110 coincides with the sectional area of the chamber interior 151 and is smaller than the sectional area of the inside of the chamber 151. There is a risk that the mixed flow may flow back by blocking the through holes 112 of the primary perforated plate such as impurities which may be mixed with the aquaculture water if they are tightly fitted between the inner wall of the chamber and the primary perforated plate, It is more preferable that there is a gap between the primary perforated plate 10 and the inner wall of the chamber.

The support 111 for supporting the primary perforated plate 110 at the upper portion of the chamber interior 151 is not required when the primary perforated plate 110 is attached to the inner wall of the chamber, And may be connected to the upper side of the chamber 150 as shown in FIGS. 2 and 3, or may be connected to the side or the lower side of the chamber 150, And may be connected to the supply pipe 130 or the secondary perforated plate 120. The arrangement of the supporting posts 111 is not limited to the above, and it is preferable that all the arrangements capable of supporting the primary perforated plate 110 in the upper part of the inside of the chamber 151 are desired.

The secondary perforated plate 120 further refines the microfine oxygen in the primary perforated plate 110 and interferes with the flow of the mixed flow to generate vortex and makes the flow trajectory of the mixed flow longer, Thereby further increasing the concentration of super-oxygenated oxygen. Therefore, it is preferable that a plurality of the secondary perforated plates 120 are spaced apart from each other so as to induce a vortex flow while simultaneously making the flow trajectory of the oxygen-cultured water mixed flow longer. The plurality of secondary perforated plates 120 may be alternately formed along the vertical direction.

FIG. 7 is a front view of the secondary porous plate 120 provided in the embodiment shown in FIG. 2 viewed from above the chamber 150, FIG. 8 is a front view of the secondary porous plate 120 provided in the embodiment shown in FIG. (120) from above the chamber (150).

As shown in FIG. 7, the secondary perforated plate 120 attached to the ultra-fine structure forming apparatus 100 of the present invention shown in FIG. 2 has a donut shape, (A in Fig. 7) in which the outer circle is not in contact with the inner wall of the chamber 150, and the outer circle is attached to the inner wall of the chamber 150 without contacting the donut- (Shown in Fig. 6B) may be alternately arranged. When the secondary perforated plate 20 is arranged as described above, the flow trajectory of the oxygen-forming water mixed flow can be made long.

As shown in FIG. 8, the secondary perforated plate 120 attached to the ultra-fine structure forming apparatus 100 of the present invention shown in FIG. 3 has a fan shape, and its central angle is not limited to 180 Lt; RTI ID = 0.0 > 360 < / RTI > If the center angle is 180 or more, the oxygen-permeated water flow that has passed through the primary perforated plate 110 can be guided to pass through the plurality of secondary perforated plates 120. The reason why the center angle is less than 360 degrees is that a gap is formed between the secondary perforated plate 120 disposed above and the secondary perforated plate 120 disposed below from which the mixed flow that has not passed through the through hole 121 can flow down For example.

The shape and arrangement of the secondary perforated plate 120 can be changed as appropriate in accordance with the shape of the chamber 150 or the arrangement of the supply pipe 130 and the plurality of secondary perforated plates 120 may have the same or different sizes . Further, the secondary perforated plate 120 may be formed to be perpendicular to the inner wall of the chamber, or may be formed to be inclined downward or upward.

The through holes 112 and 121 of the primary perforated plate 110 and the secondary perforated plate 120 may preferably have a diameter of 5 to 15 mm. When the diameter of the through holes 112 and 121 exceeds 15 mm, a large amount of oxygen bubbles having a diameter of 1 micrometer or more is generated, and a vortex is formed to a small degree, thereby decreasing the concentration of oxygen in the aquaculture water. If the diameter of the through holes 112 and 121 is less than 5 mm, the flow of the oxygen-water aqua-mixed water flow is stagnated to increase the internal pressure, and the flow of the oxygen-water aqua water mixed flow may flow backward.

The area occupied by the through holes 112 and 121 in the primary perforated plate 110 and the secondary perforated plate 120 can be about 30 to 90%, preferably about 65 to 85% %. &Lt; / RTI > If the area occupied by the through holes is less than 30% of the perforated plate area, the pressure applied to the primary perforated plate 110 and the secondary perforated plate 120 becomes too large, so that the perforated plates 110 and 120 are damaged, Water mixed flows may flow backward and oxygen-forming water mixed flows that do not pass through the through holes 112 and 121 are increased, so that the amount of super-oxygen-rich oxygen is significantly reduced. Therefore, if the area occupied by the through holes 112 and 121 is less than 30% of the perforated plate area, the installation of the primary perforated plate 110 and the secondary perforated plate 120 may be meaningless.

When the area occupied by the through holes 112 and 121 exceeds 90% of the area of the perforated plate, the oxygen-water aqua mixed flow passes mostly through the secondary perforated plate 120, As the flow trajectory of the mixed flow is shortened, the amount of super fine oxygen dissolved in the aquaculture water is significantly reduced. In addition, since the areas occupied by the through holes 112 and 121 are too wide, the durability of the perforated plates 110 and 120 may be weakened.

9 is a cross-sectional view of the water tub 200 in which the injection device 410 is installed.

Referring to FIG. 9, the second line 400 may be connected to the injector 410 to uniformly spray the ultra-fine oxygenated water generated in the ultra- And injection device 410 may include one or more injection ports 420. The spraying device 410 is preferably disposed adjacent to the bottom plate 210 or the bottom plate 210 of the water tank, since the effect of floating the foreign substances in the aquaculture water is various during various effects of the super- And the jetting port 420 may be disposed in a direction toward the water surface. However, the arrangement of the injection device 410 and the injection port 420 may be changed according to the structure of the water tub 200, the circulation structure of the aquaculture water, and the like.

10 shows a state in which the culture water inside the water tub 200 is rotated in an arbitrary direction about the separation wall 230 provided at the center of the water tub 200 by the ultra- A view from the upper part of the water tub 200. Fig.

Referring to FIG. 10, the water tub 200 may include a separation wall 230 at a central portion thereof. The separating wall 230 is a structure that can induce rotation in any one direction when the aquaculture water circulates within the water tub 200 and is installed apart from the water tub side wall 220 for circulation of the aquaculture water .

11 is a view showing a state in which the culture water in the water tank 200 is rotated in an arbitrary direction about the preliminary reservoir 240 installed at the center of the water tank 200 by the ultra- A view from the upper part of the water tub 200. Fig.

Referring to FIG. 11, the water tank 200 may include a reservoir 240 at the center, and the reservoir 240 may be spaced apart from the water tank side wall 220. The reserve reservoir 240 is a structure for storing clean raw water. When the exchange of the aquaculture water is required, providing the untreated seawater or freshwater can increase the number of bacteria in the aquaculture water. Therefore, As aquaculture. The raw water in the preliminary reservoir 240 should have a similar dissolved oxygen amount, temperature and salinity to the number of cultivars so that the subject is less stressed. When the preliminary reservoir 240 is separated from the water sidewall 220 and disposed at the center of the water tank, it is possible to induce the circulation of the water in the water tub 200, like the separating wall 230 shown in Fig. 10 .

As shown in FIGS. 10 and 11, when the culture water has a circulation structure, the oxygen can spread evenly inside the water tank 200, so that pollution of the aquaculture water is lower than that of the non-circulation structure.

As shown in Figs. 10 and 11, in order to circulate the aquaculture water, an apparatus is required to provide a force capable of circulating the aquaculture water. By suitably arranging the jetting apparatus 410 of the present invention, The supercritical oxygen-dissolved water emerging from the injection port 420 of the apparatus 410 can be induced to rotate in any one direction.

12 is a front view of the water tank 200 as seen from above when a plurality of scum collectors 260 are mounted in the water tank 200 provided at the center of the preliminary reservoir 240. Figure 13 is a front view of the water tank 200, Lt; RTI ID = 0.0 > 260 < / RTI >

In the case where the water circulation system has a circulation structure, pollutants or feeds floating on the water surface by ultra-fine oxygenated water continue to move in accordance with the flow of the aquaculture water, so that a float collecting unit Thereby facilitating their removal.

12, at least one float collecting unit 260 may be installed, and the spacing between the float collecting units 260 may be arbitrarily changed as needed, and is disposed adjacent to the water surface to collect floating matters floating on the water surface . Since the height of the water surface varies depending on the fish species, the arrangement of the scum collecting unit 260 can be freely changed according to the height of the water surface.

The float collecting unit 260 may be a rectangular flat surface as shown in FIG. 13 (a), and may be modified into various models as necessary. 13 (c) and 13 (d), in which the concave surface formed as a bend is arranged so as to face the flow direction of the water to collect the suspended matters . The use of the bent floating collecting unit 260 allows the impurities that have floated to the surface of the water to sink to the bottom of the floating collecting unit 260 formed due to the buckling of the floating collecting unit 260, It can be easy. As shown in FIG. 13 (b), the suspended solids collector 260 may include at least one through hole 261 that does not allow the suspended solids to pass therethrough but allows water to pass therethrough. In addition, the scum collection unit 260 may further include a device for removing collected scum. In addition, impurities can be sucked by mounting a pump to remove impurities that sink to the bottom.

In Comparative Example 1, since the primary perforated plate was not provided in Example 1, the dissolved oxygen amount was reduced by about 42% as compared with Example 1, and no super strength was produced. Since the ultracentrifugation bubbles are not well discharged in the solvent, the reduction ratio of the concentration in the solvent is much smaller than that of the large bubbles. In Comparative Example 1, bubbles having larger particle diameters than the ultra- 1.

In Comparative Example 2, no primary perforated plate was provided in Example 7, and the dissolved oxygen amount was reduced by about 43% as compared with Comparative Example 1 and Example 1, and the oxygen concentration The reduction rate was increased more than twice.

It can be seen from the comparison between Comparative Examples 1 and 2 and Examples 1 and 7 that the primary perforated plate is an essential constituent for the generation of ultra fine grained bubbles and the increase in the melt concentration of super fine grained bubbles. In Example 7, the amount of dissolved oxygen was increased by about 37% compared to that in Example 1 because two of the Example 1 were connected in series. When a plurality of the devices according to the present invention were connected in series, It can be seen that the concentration can be increased.

In Example 1, the area occupied by the through holes in the primary and secondary perforated plates was 75%, whereas in Comparative Example 3, the area was set to 25%, the dissolved oxygen amount was reduced by about 32% as compared with Example 1, The decrease rate of the oxygen concentration was increased by about 1.9 times. The degree of increase of the dissolved oxygen amount and the decrease rate of the oxygen concentration were similar to those of Comparative Example 1 without the primary perforated plate, If set, it means that the installation of the primary die plate is meaningless.

In Comparative Example 4 in which the structure is the same as that of Example 1, and the area occupied by the through holes in the primary and secondary perforated plates is set to 10%, the mixed stream ejected from the feed pipe receives back pressure from the primary perforated plate , The mixing flow from the supply pipe was not smooth, and the mixed flow also flowed back into the supply pipe, and the experiment itself could not proceed.

In Comparative Example 5 in which the structure was the same as Example 1 but the area occupied by the through hole was 95%, the dissolved oxygen amount was reduced by about 37% and the oxygen concentration decreasing ratio was increased by about 1.5 times as compared with Example 1, In Example 5, the ratio of the through holes was too large to form vortex, and the amount of water passing through the perforated plate was increased, so that the flow trajectory was shortened and the amount of dissolved oxygen was greatly reduced.

It can be seen from the results of Comparative Examples 3 to 5 that the area occupied by the through holes in the perforated plate is preferably about 30 to 90%.

< Manufacturing example - Manufacture of a farm containing ultra-fine bovine vesicle production devices>

The culture plant was prepared by connecting the micro-centrifuge cell producing apparatus of Example 1 with a water tank of 100 m width, 70 m length and 1.5 m height. The connection was made up of two pipes: a pipe for sucking the aquaculture water in the water tank and a pipe for the ultra-fine aerobic oxygenated water generated in the ultra-fine bubble generator.

In the central portion of the water tank, a wall was formed 15 m inward from the side wall, and a reservoir 70 m long, 40 m long and 1.5 m high was installed, and the side wall of the reservoir and the side wall of the water reservoir were connected to each other, A plurality of scum collecting units were installed as shown in Fig.

In order to make circulation flow of the aquaculture water, as shown in Fig. 11, two jetting apparatuses were arranged in parallel to each other, and the ultra-fine strength generating apparatus of Example 1 was also connected to each jetting apparatus Two of them were installed.

When various foreign substances such as water and feed were put in a water tank, and Example 1 was operated, it was ascertained that foreign substances floated to the surface of water and circulation flow in which water rotated in one direction.
