Description

Dual airlift unit

The present invention relates to an air lift apparatus, and more particularly, to a dual air lift apparatus in which a plurality of air lift apparatuses having different heights are arranged to form water flow even during a process of replacing aquaculture water in aquaculture farms.

The present invention also relates to a factory farm, and more particularly, to aquaculture water exchange system capable of improving the water quality of aquaculture water of a plurality of farms.

In addition, the present invention relates to a plant farm, and more particularly, to a culture tank having a culture tank deformation prevention device that can prevent deformation of the culture tank formed of a thin synthetic resin material, such as PP, PE and the like.

The present invention also relates to a factory farm, and more particularly, to a farm farm that can be easily managed using a crane, and to control the internal temperature of the farm using waste heat, geothermal heat, and the like.

The present invention also relates to an air supply, and more particularly, to an air supply and an air lift apparatus having the same, which can be easily formed in the form of a coil spring.

The present invention further relates to aquaculture farms and, more particularly, to aquaculture farms having shell shells of shellfish, such as shrimp, and shelling and waste cleaning systems.

As farming methods, such as fish and shrimp, have been transitioning from low density pond farming to high density tank farming, the burden on facilities and operating costs tends to increase.

In recent years, high density circulating filtration farms have been used in recent years by using aberrations, air air supply, or even liquid oxygen, high pressure oxygen, oxygen generators, etc. The farm is operated in the same way.

In addition, in the case of using pure oxygen such as liquid oxygen, a de-gassing apparatus is used to reduce poisonous carbon dioxide generated by fish in the water, or a foamer is used to remove dissolved organic matter. And so on. However, these devices are expensive because they are expensive, and there is a problem in that they are expensive to manage and operate such devices.

In order to solve such a problem, Korean Patent Application No. 10-2011-0090665 "Aquaculture System and Shrimp Farming Method Using an Air Lift Device" includes supplying air into a pipe and discharging fine air bubbles along with water inflow. An air lift apparatus for providing oxygen has been disclosed.

However, in the conventional "aquaculture system and shrimp farming method using the air lift apparatus", when the water level is lowered, because the air bubbles are not discharged from the air lift apparatus can not continuously supply oxygen to the water to increase the water level, and thus operating The cost is greatly increased.

On the other hand, as a related art, Korean Patent Registration No. 10-1438678 discloses an air lift apparatus having a slide body that can be lifted to solve such a problem. At this time, it is recommended to submerge the air supply to the position closest to the bottom of the farm to form a strong water flow. If the air supply is submerged to the position close to the bottom of the farm, if sufficient air pressure is not applied. There is a problem in that air does not reach the air supply and a sufficient amount of air is not injected.

In addition, even in the case of a biofloc inland farm, after a certain period of time, it is necessary to remove colorless and odorless sediment, which is decomposed by microorganisms, such as food and fish waste contained in aquaculture. However, in order to remove the sediment from the farm, it is impossible to farm the fish during the water change process, since it is necessary to remove all the water in the farm or to discharge at least half of the farm water, and then to remove the sediment that has settled to the bottom with a shovel or a fork lane. There is an inconvenience. In particular, in the biofloc inland farm, the formation of water flow through the air lift device is essential, but if the water level drops below a certain level, it is impossible to form the water stream by the air lift device.

On the other hand, due to the increased environmental pollution, farming fish on the coast has many risks. Due to the effects of algae and climate change, as well as human oil spills and radioactive contamination, coastal cage farming can no longer provide safe food for consumers.

Accordingly, in recent years, aquaculture method has been developed to fish in a variety of ways inland rather than on the coast. In such an inland farm, an air lift apparatus is used to provide oxygen to the water inhabiting fish and to efficiently discharge carbonic acid generated by the decomposition of fish waste. Air lift device is a very important device for the growth of fish in the farm, the air lift device is disclosed in the Republic of Korea Patent No. 10-1164329 "air lift device". The conventional air lift device is composed of a pipe into which the fluid is introduced, an air supply pipe for supplying air to the bottom of the pipe, and an air disperser coupled to the air supply pipe, and the conventional air lift device generates oxygen to the farm and generates natural water flow. Has an effect.

Conventionally, in inland farming, a flow-through food that continuously inflows and outflows of farmed water or a circulating filtration system that recycles and reuses used farming water is used. However, in recent years, a separate medicine using biofloc is used. And a method of farming fish without adding antibiotics.

However, even in the case of bioflock inland farms, after a certain period of time, it is necessary to remove colorless and odorless sediments, which are decomposed by microorganisms, such as food and fish waste contained in aquaculture. However, in order to remove the sediment in the farm, after removing all the water in the farm, the sediment settled to the bottom with a shovel or fork-lane, etc., there is an inconvenience that the farming of the fish is impossible during the change process.

On the other hand, when using such a tank-type aquaculture tank, buried aquaculture tank in the basement to improve workability and heat retention and cold insulation, or cover the periphery of aquaculture tank on the bottom of the farm with soil, etc. The open upper surface of the tank may be configured to be placed at the foot of the worker, and research on the technology of forming a plurality of aquaculture tanks in a plant type by dense arrangement is being conducted.

By the way, when buried aquaculture tank or cover the surroundings with soil in this way, if the culture water is filled inside the culture tank, the culture tank can maintain the shape due to the pressure of the culture water. However, when the cultured water is removed for the replacement of the cultured water, when the thickness of the cultured water tank is thin, deformation may occur such that the side wall is crushed by the pressure of the surrounding soil.

However, in the case of a factory farm, there is a problem in that it is inconvenient for a worker to manage the plurality of tanks one by one because they operate a large scale tank. In particular, when the farm is provided in a factory type, there is a problem that the economical cost is reduced because excessive heating and heating costs are required to control the temperature inside the farm. In addition, it is possible to secure economic feasibility when a plurality of aquaculture tanks are densely arranged. However, when the aquaculture tanks are densely arranged in this way, it is difficult to secure a space through which a wagon or heavy equipment can pass. It is also inconvenient that it is inconvenient to harvest fish or farm fish.

The present invention has been made in view of the above, it provides an airlift device having an improved structure to form a normal water flow even during the process of replacing aquaculture water.

The present invention has been made in view of the above, it provides a system for aquaculture water exchange system of the plant-type aquaculture farm in which the structure is improved to perform the normal farming of fish during the change.

The present invention has been made in view of the above, it provides a culture tank of the plant-type aquaculture farm to improve the structure to prevent deformation even under pressure of the surrounding soil and the like.

The present invention has been made in view of the above, it is possible to more easily carry out the feeding and harvesting in a plurality of aquaculture tank, and to provide a factory-type fish farm with an improved structure to economically perform the water temperature control.

According to the air lift apparatus having the coil spring form, since the air supply is configured in the form of a coil spring, when the air is supplied to the air supply using an air pump or the like, it is supplied while rotating along the coil spring-shaped air supply flow path. Therefore, it is possible to easily supply air even at a deeper depth by assisting the centrifugal force.

According to the air lift device having a coil spring shape, when air is supplied to a deep depth, as the air rises to the water surface, the force of the water flow discharged from the air lift device increases, thus bringing a stronger water flow to the farm. It is possible to form. In addition, since the air moves from the depth to the surface of the water, the contact time between the air and the aquaculture water becomes longer, so that air containing more oxygen may be included in the aquaculture water.

According to the air lift device having a coil spring type, air can be delivered to a relatively deep depth as compared with a conventional air supply, so that the time between air and water contact during air ascending to the surface is increased. As a result, more oxygen can be dissolved in the farmed water, which can be helpful to fish farming.

According to the air lift apparatus having a coil spring shape, in the production stage, the core member is rolled in the form of a coil spring so as to fit the size of the air lift apparatus in which the air supply unit is installed after producing in a straight state using a metal core member. Since the feeder can be configured, it can be easily applied to air lift apparatuses of various sizes.

According to the farm, which has the shell and the shell and the waste cleaning system, the shell can be mounted on the moving path of the aquaculture water inside the tank, which is circulated by the airlift, by using a crane or the like. To reduce the hassle of eliminating shell shelling.

According to a farm that has a shell shell and a shell shell and waste cleaning system, if it is determined that the shell shell needs to be cleaned after a certain period of time, the shell shell and the tail ground cleaning system are lowered to a cylindrical form tank by using a crane. Scraped shrimp shells can be sent to the water outlet installed near the center of the tank to be removed using a shell, so that workers can enter the tank or discard all the water in the tank. Can be reduced.

According to the fish farm having the shell and the shell and the waste cleaning system, it is convenient to clean the farm by-products such as feed waste as well as the shell shell which has settled on the bottom of the tank.

Accordingly, the culture water (W1) in the culture tank 1010 is not replaced all at once, by replacing approximately 30 to 40%, it can be configured so that the fish in farming does not feel environmental changes.

The sedimentation tank 1120 receives the aquaculture water (W1) of the aquaculture tank, and primarily precipitates the aquaculture water (W1), and the primary filtered aquaculture water (W2) in which the by-products (S) such as sludge subsided. Can be formed. The sedimentation tank 1120 may form a volume larger than that of the cultured water tank 1010 so that the by-products such as sludge may be effectively precipitated by receiving the cultured water of the at least one cultured water tank 1010. In the case of aquaculture water used in biofloc farms, by-products such as sludge are kept cloudy when the rotational force is transmitted using an airlift unit. However, when the rotational force is no longer transmitted and the calm state is maintained for 1 to 3 minutes, by-products such as sludge settle very quickly without additional additives, and are separated into relatively clean aquaculture water and by-products (S). Can be.

According to this embodiment, the sedimentation tank 1120 may be installed outside the factory farm, or may be installed inside the factory farm. In addition, the sedimentation tank 1120 may be buried in the ground, it may be installed as a separate structure on the ground.

The work base 2002 may be configured to surround all of the circumferential surfaces of the culture tank body 2010, so that the upper surface of the culture tank body 2010 is positioned under the operator's foot. For example, a wall such as a fence having a height corresponding to the height of the culture tank body 2010 installed on the foundation 2001 is installed around the foundation 2001 constructed as described above, and the working base 2002 forms the culture. It is possible to build up a cement mixing soil mixed with soil and cement in a certain ratio so as to be formed up to the height of the opening of the tank body (2010). Through such a configuration, the operator can more easily perform various operations for fish farming in the culture tank body 2010, such as feeding of feed, harvesting of fish, and maintenance of airlift.

According to the present embodiment, the work base 2002 composed of the cement mixed soil may be configured by mixing the clay and the soil in a range of about 1:15 to 1:40 by using ocher or soil. According to such a configuration, the work base 2002 does not easily collapse or deform because the viscosity of the work base 2002 is increased compared to constructing a foundation using only general soil.

It is also easy.

In particular, the periphery of the culture tank body 2010 can be easily wetted during the farm management process. However, if the work base (2002) is composed of only soil, not composed of cement mixed soil, the soil is easily collapsed or smothered while being wet with water, resulting in poor workability and inability to keep the surrounding area clean. However, when the cement mixed soil as described above, it can always maintain the viscosity and rigidity of a certain level or more, it is possible to prevent the deformation of the culture tank body 2010 as well as to ensure the work cleanliness.

In addition, the work base 2002 may help to maintain a constant water temperature of the aquaculture water contained in the aquaculture tank body 2010 at all times, regardless of the external environment, such as embedding the jar in the ground.

In particular, since the soil is a main component such as soil or loess, it can be quickly absorbed and drained into the work base 2002 even if the water overflows during the farm management process, it is possible to keep the workplace clean at all times.

As shown in FIG. 23 and FIG. 24, the air supplier according to the present embodiment may include a core member 4110, a covering member 4120, and an air dispersion member 4130.

The core member 4110 may be formed of a metal material, and preferably, may be provided in a cylindrical shape. According to the present exemplary embodiment, the core member 4110 may be formed to correspond to the entire length of the air supply 4100 to form a skeleton of the air supply 4100.

The core member 4110 may be formed of a steel material in order to keep the deformed shape constant. However, the present invention is not limited thereto, and may be made of a material such as aluminum or copper.

Such a metal material is preferably composed of an inexpensive metal material for cost reduction. According to the present embodiment, the core member 4110 may have a diameter of about 1 cm to about 2 cm. However, the present invention is not limited thereto, and the diameter may vary depending on the type of metal used. For example, a material that can be easily deformed, such as copper or aluminum, may be formed relatively thick, and a material that is not easily deformable, such as steel, may be thin.

In addition, the size of the diameter of the core member 4110 may vary depending on the size of the air supply (4100). For example, when the air supply 4100 is configured to be small, the diameter of the core member 4110 may also be configured accordingly, and as the size of the air supply 4100 is increased, the covering member 4120 may be formed to have the diameter of the core member 4110. To surround the outer circumferential surface, according to the present embodiment, it may be provided with a material that can be elastically deformed.

For example, the coating member 4120 may be formed of various materials such as rubber, silicone, resin, and the like, and a urethane or PP material may also be used. The covering member 4120 is for preventing penetration of external air and moisture into the core member 4110, and may prevent the core member 4110 from being oxidized or corroded.

The covering member 4120 may be installed to the core member 4110 in various ways. For example, the coating member 4120 may be coated on the surface of the core member 4110 by impregnation or the like, and may be integrally formed with a coating or the like during injection or drawing. Alternatively, in molding the core member 4110, the core member 4110 may be formed by double injection molding.

As described above, when the core member 4110 and the cover member 4120 are formed, the cover member 4120 is elastically deformed when the coil member is molded in the form of a coil spring as in the present embodiment, without damage such as tearing. It may be modified in the same manner as the 4110. Therefore, the watertight structure can be maintained, and the corrosion or oxidation of the core member 4110 can be completely blocked by moisture or oxygen contained in the air.

The air dispersion member 4130 may be spaced apart from the cover member 4120 at a predetermined interval to form an air supply passage S between the inner circumferential surface of the air dispersion member 4130 and the outer circumferential surface of the coating member 4120. At this time, as shown in FIG. 24, the air supply passage S is configured in a donut shape, and a core member 4110 coated by the coating member 4120 may be disposed in the center thereof, and the circumferential surface is not shown. Air injected by a compressed air pump or the like may pass at a constant pressure.

At this time, the air dispersion member 4130 may be formed of a porous material having a breathable, it may be provided with a high-density air sponge commonly used in air dispersers. In this case, the air dispersion member 4130 may also be formed of an elastically deformable material. The air dispersion member 4130 is also formed to form a coil spring together with the core member 4110. If the air dispersion member 4130 is composed of a rigid body such as a commercially available air stone, since the damage may occur during the change process, the air dispersion member 4130 needs to be provided with a porous sponge material that can be softly deformed. There is.

However, the present invention is not limited thereto, and if necessary, after the air stone or the like is finished in a coil spring shape, the core member 4110 coated with the coating member 4120 may be inserted in the vicinity of the center. It is also possible to use directly without the core member 4120.

The coil spring-shaped air supply 4100 is capable of supplying air smoothly even at a deeper depth when compared to a conventional rod or air stone. That is, the conventional air stone has a disadvantage in that the air is not properly injected to the bottom surface when the air is used to sink to a deep depth, unless the pressure of the air to be supplied due to the water pressure.

However, when the air supply 4100 is configured in the form of a coil spring as in the present embodiment, it is possible to supply air to the bottom of the farm with only a smaller pressure by the centrifugal force generated during the air supply process. In addition, a larger amount of air can be injected into the cultured water, thereby increasing the strength of the water flow and increasing the amount of oxygen supplied to the cultured water.

On the other hand, the air lift apparatus according to the present embodiment can be arranged by inserting the air supply (4100) configured as described above. That is, the air lift apparatus is formed with a first diameter, the lower circumferential surface is formed with a plurality of semi-circular through holes are formed in the pipe-shaped first body into which the aquaculture water flows, and is connected to the first body and the first An air lift unit 4010 including a second body having a second diameter smaller than the diameter and having a first opening having a rectangular shape formed to have a length longer than the width of the side wall, and an inclined surface connecting the first body and the second body. And a slide body fitted to an outer surface of the second body and reciprocating along the second body and having a second opening formed at a portion facing the first opening, and a portion corresponding to the second opening of the slide body. A discharge body protruding in a direction perpendicular to the air lift unit to discharge water provided to the second opening in a direction parallel to the water surface; A slide unit 4020 and an air supply unit 4100 installed in the air lift unit to supply air to the farm, and the discharge body has an upper surface inserted into the first and second openings so that the slide Guide the unit to move between the lower surface and the upper surface of the first opening, the cross-sectional area of the water discharge portion is formed wider than the width of the portion inserted into the first and second opening, the lower surface is the slide body It can be connected roundly with respect to the outer peripheral surface of the.

On the other hand, the weight (m) may be installed at the end of the air supply device 4100 under the interposition of the wire member (4002). That is, as shown in Figure 26, the weight (m) is provided to support the air supplier 4100 in an upright state in a direction parallel to the longitudinal direction of the upper limit air lift apparatus, It can be arranged in a state of sinking to the bottom surface 4001 by the weight. Through such a configuration, the air supply 4100 may be fixedly arranged at a predetermined position up to the bottom of the farm.

According to this embodiment as described above, since the air supply 4100 is configured in the form of a coil spring, when air is supplied to the air supply using an air pump or the like, it is supplied while rotating along the air supply flow path of the coil spring shape. As a result, the air can be easily supplied to a deeper depth by assisting the centrifugal force.

In addition, when air is supplied to a deep depth, as the distance of air rises to the surface becomes longer, the force of the water flow discharged from the air lift apparatus increases, so that a stronger water flow can be formed in the farm.

In addition, compared to conventional air supplies, because air can be delivered to a relatively deep depth, air and water contact time increases during air ascending to the surface, resulting in more oxygen It can be dissolved in water, which can greatly help fish farming.

In addition, in the production step, after producing in a straight state using the metal core member 4110, by varying the diameter of the core member 4110 to suit the size of the air lift device is installed air supply 4100 Since the air supply can be configured by rolling the coil spring, it can be easily applied to various sizes of air lift apparatus.
