Description

Lightweight land-based fish farm using double pipe {Lightweight aqua farm using double pipe}

The present invention relates to a land-based fish farm, and uses a double pipe structure consisting of an inner frame made of polyethylene and an outer frame made of polyethylene as a frame to reduce weight, and the frame is formed so that it can be installed and dismantled by simple assembly. This relates to a land-based fish farm that allows users to operate easily and efficiently.

Recently, with the development of aquaculture technology, the technology to culture target organisms in tanks on land rather than in the sea has been established, and by further developing this, a culture method with the concept of cultivating various fish and shellfish by floor and tank within controlled facilities such as urban areas has been developed. It is appearing.

In general, seawater aquaculture is broadly divided into land-based aquarium farming and marine cage farming. Land-based aquarium farming is a method of cultivating target organisms by transferring them from the sea, where environmental changes are difficult to predict, to a tank on land where the habitat environment can be artificially controlled. The marine cage method is a method of trapping and raising living creatures by installing nets in a large space in the sea.

Recently, when fish and shellfish are farmed from the stage of fry or spat in cage farms at sea, the time exposed to the risk of natural disasters becomes longer, and the yield decreases accordingly, so in order to improve this problem and increase the yield, aquaculture provided on land is introduced. There is an increasing trend in cultivating fish and shellfish at high densities in aquariums and, once they grow to a certain size, cultivating them in cage farms until they reach commercial value.

Aquaculture tanks installed on land are equipped with various facilities such as breeding water supply and drainage facilities, purification facilities or oxygen supply facilities, and water temperature control devices to create an optimal environment for the growth of aquatic animals in order to cultivate marine products, animals and plants at high density. By installing the equipment, aquatic life is protected in a certain environment and a breeding environment suitable for aquaculture is formed, producing production up to a certain size.

Meanwhile, green houses including land-based fish farms are generally manufactured in the form of greenhouses. A typical greenhouse is a facility for growing and producing crops such as field crops, flower plants, and fruit trees regardless of the season. It uses the radiant heat of daytime sunlight and has a roof to prevent moisture inside the house from evaporating. is made of vinyl.

The environment of these greenhouses must be adjusted with careful consideration of temperature control and amount of light depending on the type and nature of the organisms being reared. Typically, in fish farming, an additional external greenhouse is installed outside the existing greenhouse and used to control the organisms. Their characteristics are appropriately adjusted.

These conventional greenhouses are basically installed using a frame made of steel pipes, but this raises the problem of difficulty in installation during work due to the heavy weight of the frame and its long circular shape. In addition, waste that has passed its expiration date has arisen. There is also a problem where greenhouses are not demolished on time and are left abandoned, turning into an eyesore on farms.

In addition, these greenhouses induce a greenhouse effect by layering insulation materials on the inside and outside of the greenhouse to maintain an appropriate temperature for crops. However, this only serves as a simple cover during severe cold such as sudden temperature drops or heavy snowfall, so it may not provide efficient insulation. In addition, when the insulation material is applied to the outside, the weight of the greenhouse itself is doubled, which increases the risk of collapse, causing many problems such as the death of farmed fish species.

The present invention uses a double pipe structure consisting of an inner frame made of polyethylene and an outer frame made of polyethylene as a frame to reduce weight, and the frame is formed so that it can be installed and dismantled in a simple assembly method, allowing the user to do the work. We aim to provide a land-based fish farm that can be constructed easily and efficiently.

Fish farms in Korea generally must block strong solar heat during the daytime in the summer and provide adequate ventilation to prevent the temperature of the farm from rising rapidly. Additionally, in the winter, a lot of energy is consumed for heating and keeping fish farms warm, so an aquaculture system that can reduce energy costs by maximizing energy efficiency is needed. The present invention uses a double pipe structure consisting of a double structure of an inner frame made of polyethylene and an outer frame made of polyethylene as a frame to reduce weight, while reducing weight by using a double pipe formed so that the frame can be installed and dismantled in a simple assembly method. Provides a land-based fish farm. Hereinafter, the present invention will be described in detail through specific examples.

Figure 1 shows a land-based fish farm in the form of a greenhouse, and Figure 2 shows the skeleton of a greenhouse. A typical land-based fish farm has at least one insulating wall 200 that can reduce heat transfer between the outside and the inside, a space 110 that connects the top of the insulating wall to partition the space of the fish farm, and has an air layer that receives solar heat and is heated. It includes a layered roof 100 and a pump 300 that moves air heated by solar heat from the roof 100 to the inside of the fish farm.

Figure 2 shows the skeleton forming the basic house frame of a land-based fish farm. The framework of the fish farm is formed in a streamlined shape to form a space for cultivating aquaculture organisms, and the frame connecting the walls and roof on both sides is segmented into multiple pieces, and the ends of each are assembled together using joints to form a house frame.

The skeleton that makes up this type of fish farm is installed using a frame made of steel pipes, like greenhouses on land. However, this frame is heavy and has a long circular shape, making installation difficult, and also requires metal material depending on the expiration date. There was a problem with durability due to the formation of rust, and since the skeleton material was made of steel, heat exchange between the metal surface and the external temperature was not easily achieved, which caused a problem that greatly affected the temperature change inside the fish farm.

In order to solve the problems of existing metal fish farm skeleton pipes, the present invention manufactures a multi-layer structure in the shape of a pipe made of a polymer compound, which not only increases strength but also has a semi-permanent functionality that can maintain buoyancy even when partially damaged. It was allowed to happen.

Figure 3 shows the internal frame of a skeletal pipe for a fish farm. The inner frame consists of a cylindrical bottom surface that is open at the top and bottom, and the middle part of the top and bottom is closed by the bottom, and a hole for air movement is formed in the center of the cylindrical bottom surface. The upper and lower outer surfaces are formed to the size of the diameter of the inner circumference of the outer frame of the skeleton pipe, and the bottom surface of the middle part is formed to the size of the diameter of the outer circumference of the outer frame of the skeleton pipe, so that the middle part protrudes at a certain height. In addition, support plates 40 are formed on the open cylindrical portions of the upper and lower surfaces to internally support the upper and lower outer surfaces of the cylindrical shape (Type A).

Another form of the inner frame 20 of the present invention has an open upper surface and a bottom surface 30, and may have a cylindrical shape with a hole for air movement in the center of the bottom surface, and an upper outer surface 35 ) is formed to the size of the diameter of the inner circumferential surface of the outer frame of the gandap stand (10), and the bottom surface may be formed to the size of the diameter of the outer circumferential surface of the outer frame of the gandap stand (Type B).

Figures 4 and 5 show skeletal pipes for fish farms manufactured by the present invention. The skeletal pipe for a fish farm of the present invention includes a skeletal pipe external frame (10) that has a cylindrical cross-sectional structure and is formed in a cylindrical structure of a certain length; Inside the skeleton pipe body, the skeleton pipe internal frame 20, which has a cylindrical cross-sectional structure and is formed as a cylindrical structure of a certain length, is arranged at regular intervals and is combined with the skeleton pipe body to form a double structure. The outer frame 10 of the present invention is made of polyethylene and is combined with the inner frame to form protrusions 21 at regular intervals on the outer surface of the skeletal pipe body. The length of the internal frame can be changed depending on the diameter and thickness of the external frame, and can usually be set in the range of 10 to 12 cm for skeletal pipes.

The protrusions formed on the outer frame 10 at regular intervals are formed by melting the polyethylene raw material and extruding it on the outside of the inner frame during the outer frame manufacturing step in the manufacturing method of the skeleton pipe for seaweed farming of the present invention, so that the melted polyethylene raw material is formed on the protrusions of the inner frame. As it is applied to the outer surface and hardens, it increases the bonding efficiency of the outer frame and inner frame. By protruding to the outside of the outer frame by the height of the protrusion of the inner frame, it is possible to prevent bending and increase the restoring force of the skeleton pipe.

<Manufacturing of skeletal frame for fish farms>

The skeletal pipe for a fish farm of the present invention has a cylindrical cross-sectional structure inserted into the outer frame of the skeletal pipe, and includes an internal frame preparation step (a) of preparing an inner frame of the skeletal pipe formed into a cylindrical structure of a certain length; An external frame forming step (b) of sequentially inserting the internal frame prepared in step (a) into an external frame forming device and extruding the external frame on the outer surface of the internal frame to manufacture a skeletal pipe body formed of a double material structure; A cooling step (c) of hardening the extruded outer frame by cooling the skeletal pipe outer frame manufactured through step (b) at room temperature or cold water; The above step (c) may be comprised of an installation step (d) of fixing the completed skeleton pipe external frame to the fish farm skeleton.

(A) Skeleton pipe internal frame preparation stage

The skeletal pipe inner frame preparation step (a) of the present invention includes preparing a circular-shaped inner frame made of polyethylene. The internal frame is a skeletal pipe that is formed to a length and thickness that can be used as internal reinforcement. In the polyethylene processing step, it is desirable to mold the inner frame of the skeleton pipe by injecting molten polyethylene into a mold so that it is formed to fit the inner peripheral surface of the outer frame to a length of about 3 cm.

A hole for air movement is formed in the center of the bottom of the inner frame of the skeleton pipe. The air movement hole forms an air movement hole of a certain size to solve the problem that when the external frame is applied to the outside of the internal frame, the pipe may shrink or burst due to air expansion when the air in the space is heated or cooled. This is to facilitate air movement due to expansion and contraction of air.

(B) External frame forming stage

The outer frame forming step (b) of the present invention is a step of sequentially inserting the inner frame prepared in step (a) into the outer frame forming device to manufacture a skeletal pipe body in which the inner frame is inserted and installed inside the outer frame. .

The external frame molding apparatus of the present invention is a device capable of extrusion molding polyethylene, including a discharge part through which molten polyethylene raw material is extruded and discharged, a die that controls the discharge and discharge amount of the raw material in the lower direction of the discharge part, and It is installed to face the die, moves horizontally after the inner frame is placed, and applies the plastic raw material discharged from the die. It may be composed of a moving part that can extrude the outer frame around the side of the inner frame.

The thickness of the outer frame can be adjusted according to the speed of the moving part and the amount of molten polyethylene discharged from the die. As the molten polyethylene is melt-bonded with the inner frame, the protruding portion of the inner frame overlaps the outer frame and protrudes outward. It is molded to form a protrusion 21 to form a convex node, thereby increasing the bonding force between the inner frame and the outer frame.

According to an embodiment of the present invention, the thickness of the outer frame is preferably 1 to 3 mm, and the distance between the inner frames is preferably 5 to 10 cm.

(c) Cooling stage

The cooling step (c) of the present invention is a step of hardening the external frame by cooling the skeleton pipe manufactured through step (b) above at room temperature or in cold water. At this time, the moving part of the external frame forming device is connected to the cooling part, so that the skeleton pipe transferred from the moving part can be continuously cooled. The cooling step of the present invention is a step in which the skeleton pipe, on which the work of forming the external frame has been completed, is continuously moved to the cooling section through the moving section and solidified. Most of the above-applied raw materials are thermoplastic resins that can be cooled and solidified at room temperature or cold water, so it is possible to produce multi-layered skeletal pipes through a solidification process using cooling water or at room temperature for a certain period of time. According to an embodiment of the present invention, the length of the completed skeleton pipe is 2 m and may have a diameter of 2 to 4 cm.

<Skeleton frame manufacturing equipment for fish farms>

Figure 6 shows a side view of the manufacturing apparatus for the skeletal pipe for fish farms of the present invention. The manufacturing device for the multi-layer skeletal pipe for fish farms includes a coating device (10) through which polyethylene raw material in a molten state is discharged to extrude the outer frame to the outside of the inner frame; A die (11) that controls the discharge and discharge amount of the raw material in the downward direction of the coating device; It may be composed of a moving part 12 that moves the inner frame so that the raw material discharged from the coating device is extruded and applied to the outside of the inner frame.

Typically, the moving part is connected to a rotation motor, and the internal frame placed on the moving part moves horizontally while rotating centrifugally on one side. Therefore, on the outside of the inner frame, extrusion molding of molten polyethylene raw materials is performed while rotating and moving horizontally to form an external pipe.

The molten polyethylene raw material of the present invention is obtained by injecting each raw material into the primary coating device 61, secondary coating device 62, and tertiary coating device 63, which constitute the coating device of the skeleton pipe manufacturing device. It can be done in stages. For each device constituting the coating device, a hopper into which raw materials are introduced and an extruder and die for melting the input raw materials are installed, and each device can be installed depending on the purpose of molding.

The primary coating device 61 is a device capable of extrusion molding molten polyethylene, and includes a discharge part 15 through which the molten polyethylene raw material is extruded and discharged, and a die that controls the discharge and discharge amount of the raw material in the downward direction of the discharge part. (11), after the inner frame is installed to face the die, it moves in the horizontal direction and extrusion molding of the plastic raw material discharged from the die is performed, and movement is performed to extrude the outer frame around the side of the inner frame. It may be made up of parts (12).

The secondary coating device 62 is a device that coats the external frame with color or functional material. The raw materials input into the hopper may be polyethylene resin, colored dye, near-infrared absorbing dye, and ultraviolet absorber. The composition of these raw materials not only suppresses oxidation of the resin by suppressing the deterioration caused by near-infrared and ultraviolet rays for the resin exposed to sunlight, but also serves as a guide to the location and slope of the terrain through distinct colors. do.

The colored dye can be selected as an organic pigment corresponding to the desired color, and the near-infrared absorbing dye is a binder made by dissolving polymethyl-methacrylate in NMethyl-2-pyrrolidone. It can be formulated by adding a sunscreen, and the benzotriazole type 2-(2'-hydroxy-3'-tert-butyl-5'-methyl ??phenyl)-5-chlorobenzotriazol can be selected. .

The raw material inputted into the secondary coating device 62 is a luminous material and can be applied to the outer surface of the external frame by adjusting the application shape.

The 3rd coating device 63 is a transparent coating material, and the input raw materials can be polyethylene resin, near-infrared absorbing dye, ultraviolet absorber, and antioxidant. It prevents wear of the skeleton pipe for seaweed farming and acts as a waterproof and antifouling agent to protect the skeleton pipe. The frequency of replacement work due to damage can be reduced.

A core is installed in the discharge portion 15 of the die 11, which is commonly installed in the coating device, to enable adjustment of the discharge amount, discharge cycle, and discharge speed of the raw material, and the moving portion 12 also rotates and rotates the core portion. Movement speed can be adjusted. By adjusting the discharge speed of the moving part and the dice, it is possible to intermittently supply the discharge amount to the internal frame to form a pipe of a certain thickness.

Figure 7 shows a transfer device for the internal frame constituting the skeleton pipe manufacturing device. The internal frame transfer device is a device that is formed at the starting point where the primary coating device is driven and supplies the internal frame at a constant speed. The internal frame transfer device consists of an automatic supply sorter (50) that collects the internal frames to be used in the manufacture of skeleton pipes for seaweed farming and supplies them by sorting them by size, and a transfer pipe (55) for moving them to the primary applicator. The transfer pipe is connected to the moving unit 12, and an air supply unit 70 capable of supplying high-pressure air is formed between the transfer pipe and the transfer unit.

The automatic supply sorter (50) stores internal frames for each size, and a variable space can be formed at the bottom of the automatic supply sorter (50) so that the internal frames to be manufactured according to the pipe size of the skeleton pipe can be selected and supplied. The device means is formed. The variable space is formed by a roller that rotates while the space width is adjusted in the left and right horizontal directions by the sorting motor 51, so that only the internal frame with a certain diameter width can pass through and be sequentially supplied to the transfer pipe.

The moment the internal frame transferred from the automatic supply separator (50) to the transfer pipe (55) enters the moving part (12), the moving part is moved by the high-pressure air sprayed from the air supply part (70) and is used as polyethylene raw material for the primary coating device. It is moved to the discharge part 15 where it is extruded and discharged. The high-pressure air discharged from the air supply unit 70 is discharged intermittently at regular intervals to form a gap between the internal frames and moves the internal frame transferred from the automatic supply separator 50 within the moving unit 12. . In order for the internal frame to move inside the moving unit through the air supply unit, the internal frame forms a cross-shaped partition and a bottom surface as in the present invention, so that it can move inside the moving unit by receiving resistance from high-pressure air.

The internal frame moved to the discharge unit is extruded to a certain thickness using the moving speed of the moving unit and the molten polyethylene discharged from the die to form an external frame having an internal frame structure at regular intervals. As molten polyethylene is extruded onto the protruding portion of the inner frame, an outwardly protruding protrusion 21 is formed on the outer frame to form a convex node.

The protrusions formed on the outer frame 10 at regular intervals are formed by melting the polyethylene raw material and extruding it on the outside of the inner frame during the outer frame manufacturing step in the method of manufacturing the skeletal pipe for aquaculture of the present invention. As it is applied to the outer surface and hardened, it increases the joint efficiency of the outer frame and the inner frame, and by protruding to the outside of the outer frame as much as the height of the protrusion, it is possible to prevent bending and increase the restoring force of the skeleton pipe. The protrusion may act as a stopper to prevent the fixing part from moving when a connecting device fixed to the external frame of the skeleton pipe is coupled.

By reducing the weight and increasing the lifespan of the skeleton pipe installed in the fish farm of the present invention, maintenance and repair costs are reduced for related fishermen, and it is possible for related industrialists to use it industrially because it helps create profits through increased demand.
