Description

{Method for manufacturing for seaweed culture pipe.}

The present invention relates to a stand for seaweed farming that fixes seaweed in a seaweed farm. Regarding the seaweed farming rod, which is resistant to corrosion in seawater and has improved strength resistance, including a pipe-shaped rod body composed of a double structure of an inner frame made of polyethylene and an outer frame made of polyethylene, and a part that is fixed to the rod body. will be.

Wild seaweed mainly grows on rocks in the upper intertidal zone, but is a representative seaweed that grows well on various other adherent substances. Because of these characteristics, it was the first to be developed as a species to be farmed, laying the foundation for our country's aquaculture industry.

In order to cultivate seaweed, a substrate suitable for growth must be provided. The first form of seaweed was to stick twigs or bamboo sticks into the tidal flats and allow the seaweed to grow there. Later, bamboo poles made by splitting and plaiting bamboo were used. Recently, Kimbal, a net woven from synthetic fibers, has been widely used.

There are two ways to install gimbal: the pole-type farming method, which involves hanging the horse poles upright, and the hanging-foot farming method, which installs them using moxa and anchors. The horse-tree style (holding style) is a method that has been widely used for a long time. It involves planting a horse-tree made of pine or oak on the bottom in waters shallower than 10m, and hanging a gimbal horizontally on it. The height of the gimbal is set to approximately the 4-5 hour exposure line. Since seaweed grows in the upper intertidal zone, it takes advantage of the ecology of living alternately in the air and underwater depending on the tide.

At this time, the malmok that fixes the gimbal is usually called a gandapdae. In the past, natural materials such as bamboo or straight, long wood were used as ganja. However, since the pad made of natural materials is used with almost no processing steps, the pad standards are not uniform and it has the disadvantage of having a short lifespan when installed in seawater for a long period of time.

Accordingly, efforts were made to make up for the shortcomings of Gandapdae, which was coated with synthetic resin on the surface of bamboo, a natural material, to compensate for its vulnerability to seawater. However, due to the high breakage rate and the heavy weight of the natural material itself, materials such as carbon fiber and fiber-reinforced plastic have recently been used. A built-up stand is provided.

Although the pad made of the above plastic material is strong against seawater corrosion, there is a problem in that it is installed while submerged in seawater, so it bends due to the elastic force of the material itself due to strong waves or waves, and the resulting damage rate is high. In particular, the above-mentioned bending phenomenon causes problems such as loss of restoring force, causing the net to come off or the connection part of the float to be damaged.

Accordingly, Domestic Patent No. 10-1855817 discloses an invention regarding a gimbal pad made of FRP material and its manufacturing method, but the material was difficult to put into practical use due to the high cost compared to the unit price. The present invention seeks to provide a method of manufacturing a double-structured seaweed farming platform that is resistant to corrosion even when installed in seawater for a long period of time, has improved rigidity and durability, and can reduce economic burden.

Domestic registered patent number 10-2065918 discloses a joint structure for seaweed farming that connects a pair of rods installed at a certain interval on a floating device for aquaculture to maintain the gap between the rods. . Domestic registered patent number 10-1855817 states that after molding FRP into a cylindrical tube shape, protruding rings are formed at regular intervals on the outer diameter, and a synthetic resin coating pipe is combined with the outer diameter of the FRP pipe and the protruding ring and coated with synthetic resin by heating. Disclosed is a gimbal gandap pole that can quickly tie a rope without being corroded by seawater by coating and fixing the pipe in an integrated manner as it heat-shrinks, and a method of manufacturing the same. Domestic Registered Utility Model No. 20-0284565 relates to a Gandap pole used for farming seaweed, seaweed, and abalone. More specifically, the inside of the Gandap pole is equipped with a “Y”-shaped reinforcing bar and a plurality of reinforcing iron cores. This prevents the gandap from breaking or bending due to strong waves or wind. At both ends of the gandap, a joint where the stopper is attached is formed. By sealing both ends of the gandap with a stopper, foreign substances are prevented from penetrating into the inside of the gandap. Disclosed is a pad for marine aquaculture equipped with a reinforcing pole and a reinforcing iron core. Domestic Patent Publication No. 10-2009-0002834 discloses a gandabdae on which a rope is installed, which consists of a main body formed of a tube and caps installed at both ends of the main body: the cap has a symmetrical cut in the longitudinal direction at one end. an appearance formed at an inner end of the incision with a rope seating portion for seating the rope larger than the size of the incision; A partition formed vertically inside the exterior; Disclosed is a gandap stand that protrudes from the partition and includes an inner tube formed inside the outer tube along the longitudinal direction of the outer tube, and in which the main body is inserted into a groove formed by the inner tube and the outer tube.

The present invention is intended to solve the weak strength and vulnerability to seawater corrosion that occurs in existing wooden and plastic joints. It is resistant to corrosion even when installed in seawater for a long period of time, has improved rigidity, excellent durability, and is more economical. We provide a multi-layer structure for seaweed farming that can reduce the human burden.

In addition, since the bottom of the bottom of the inner frame of the Gandap stand is located inside the outer frame of the Gandap stand, a protrusion 21 is formed so that the bottom portion of the lower surface protrudes outward from the outer peripheral surface of the outer frame of the Gandap stand during extrusion molding of the main body of the Gandap stand, It provides a gandap stand for seaweed farming in which the father and son surrounding the outside of the outside frame of the gandap stand are combined.

Hereinafter, the manufacturing method of the multi-layered seaweed farm of the present invention and the configuration related to the multi-layer seaweed farm produced by the manufacturing method will be described in detail with the accompanying drawings.

The existing seaweed farm stand was manufactured in the shape of a pipe made of a polymer compound, and then both ends were blocked to make the inside hollow. Such padding has the disadvantage of being subject to significant wear and damage due to ultraviolet rays or continuous use by users, and has a disadvantage of being easily broken by waves or swells due to its weak strength. The present invention is manufactured using a method for manufacturing a multi-layered structure, so that it not only increases strength but also has semi-permanent functionality that can maintain buoyancy even when partially damaged.

Figure 1 shows a schematic diagram of the method of manufacturing gandapdae for seaweed farming of the present invention. The method of manufacturing Gandapdae for seaweed farming of the present invention includes an internal frame preparation step (a) of preparing an internal frame of Gandapdae, which is formed into a cylindrical structure of a certain length and has a cylindrical cross-sectional structure inserted into the outer frame of Gandapdae; An external frame forming step (b) of sequentially inserting the internal frame prepared in step (a) into the external frame molding device to manufacture a gandapdae body in which the external frame is extruded and molded on the outer surface of the internal frame to form a double material structure; A cooling step (c) of hardening the extruded outer frame by cooling the outer frame of the Gandapdae manufactured through step (b) at room temperature or cold water; Step (c) above may be accomplished by inserting and fixing the outer frame of the gandap stand into the through hole of the buoyancy material to install the buoyancy material (d).

Figure 2 shows a side view of the manufacturing device for the multi-layered seaweed farm of the present invention. The manufacturing device of the multi-layered seaweed farm for seaweed farms includes a coating device (10) through which polyethylene raw material in a molten state is discharged to extrude the outer frame on 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 pad 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 and tear of the seaweed stalk for seaweed farming and acts as a waterproof and anti-fouling agent to prevent damage to the stalk. This can reduce the frequency of replacement work.

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 3 shows the internal frame of the gandap stand for seaweed farming. The inner frame is made of a cylindrical shape with the upper and lower sides open and the middle part of the upper and lower sides closed by the floor. The upper and lower outer surfaces are formed to the size of the diameter of the inner circumferential surface of the outer frame of Gandapdae, and the bottom surface of the middle part is the outer circumferential surface of the outer frame of Gandapdae. It is formed to the size of the diameter and 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 type of Gandapdae internal frame (20) of the present invention may be formed in a cylindrical shape with the upper surface open and the lower surface closed by the bottom surface (30), and the upper outer surface (35) is the Gandapdae external frame (10). It is formed to the size of the diameter of the inner circumferential surface of the bottom surface, and the bottom surface can be formed to the size of the diameter of the outer circumferential surface of the outer frame 10 (Type B).

Figure 4 shows a transfer device for the internal frame constituting the gandandae 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 is composed of an automatic supply sorter (50) that collects the internal frames to be used in the production of 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 is a device that can form a variable space at the bottom of the automatic supply sorter (50) so that the internal frames to be manufactured according to the pipe size of the pipe can be selected and transported. The 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 seaweed for cultivating seaweed of the present invention. As it is applied to the outer surface of the protrusion and hardened, it increases the bonding efficiency of the outer frame and the inner frame, and by protruding to the outside of the outer frame by the height of the protrusion, it can prevent bending and increase the restoring force of the gandap. The protrusion may act as a stopper to prevent the fixing part from moving when the buoyancy material 200 fixed to the external frame of the gandapdae is coupled.

Figures 5 and 6 show the gandapdae for seaweed farming manufactured by the manufacturing method of the present invention. The Gandapdae (100) for seaweed farming of the present invention has a cylindrical cross-sectional structure and includes an Gandapdae external frame (10) formed in a cylindrical structure of a certain length; Inside the gandap stand main body, the gandap stand 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 gandap stand 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 main body of the gandabdae.

The Gandapdae internal frame (20) of the present invention is made in a cylindrical shape with the upper surface open and the lower surface closed by the bottom surface (30), and the upper outer surface (35) is the size of the inner peripheral surface diameter of the Gandapdae external frame (10). It is formed and the bottom surface can be formed to have the size of the diameter of the outer circumferential surface of the outer frame 10. 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 a gandap stand.

The internal frame of another embodiment of the present invention is made of a cylindrical shape with the upper and lower surfaces open and the middle part of the upper and lower surfaces closed by the bottom, the upper and lower outer surfaces are formed to the size of the diameter of the inner circumferential surface of the outer frame of the gandabdae, and the bottom surface of the middle part is It is formed to the size of the diameter of the outer circumference of the outer frame of the Gandapdae, and 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.

Additionally, irregularities may be formed on the upper outer surface 35 in the horizontal or vertical direction. As irregularities are formed horizontally or vertically, the outer frame is melted and extruded onto the upper and outer surfaces of the inner frame, thereby increasing the bonding force between the inner frame and the outer frame.

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 production step in the method of manufacturing seaweed for farming according to the present invention, so that the molten polyethylene raw material is formed on the protrusion 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 equal to the height of the protrusion of the inner frame, it is possible to prevent bending and increase the restoring force of the gandap. When the buoyancy material 200 fixed to the external frame of the Gandapdae is coupled to the protrusion, the fixed portion of the buoyancy material may act as a stopper to prevent slipping so that the fixed portion of the buoyancy material moves between the protrusions of the Gandapdae.

<Examples for each manufacturing step>

(a) Internal frame preparation stage

The internal frame preparation step (a) of the present invention includes preparing an internal frame of a circular shape made of polyethylene. The internal frame is molded to a length and thickness that can be used as internal reinforcement. In the polyethylene processing step, it is desirable to inject molten polyethylene into a mold so that the length of the inner frame of the gandapdae is about 3 cm and is formed to fit the inner peripheral surface of the outer frame.

(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 molding device to manufacture a gandab body with a structure 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 pad manufactured through step (b) above at room temperature or in cold water. At this time, the moving part of the external frame molding device is connected to the cooling part, so that the joints transferred from the moving part can be continuously cooled. The cooling step of the present invention is a step in which the outer frame-forming work 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 pads 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 gandapdae may be 2 m and the diameter may be 2 to 4 cm.

(D) Buoyancy material installation stage

The buoyancy material installation step (d) of the present invention is a step of inserting both end portions of the gandab on which step (c) has been completed into the through holes of the buoyancy material and fusing or fixing the received contact surfaces. The contact surface can be fused by inserting the buoyancy material into the completed outer frame of the gandab and applying heat.

Figures 7 and 8 show a combined embodiment of the seaweed farming platform and buoyancy material of the present invention. The stand for seaweed farming of the present invention is made of polyethylene material and forms a cylindrical partition wall protrusion by combining an internal frame inside the stand to prevent bending, twisting, and restoring force, thereby forming a protrusion on the outside of the stand. As shown in Figures 5 and 6, the protrusion has a structure that protrudes at regular intervals from the outside of the external frame and can be used as a stopper to secure the coupling member of the buoyancy material when combined with the buoyancy material.

The spacing of the protrusions formed on the outer frame of the Gandapdae can be adjusted to have an arbitrary position by adjusting the spacing between inserting the inner frame during extrusion molding. Arbitrary positioning can maximize the function of the gandap stand by adjusting the length of the internal frame with a partition wall in consideration of preventing bending of the gandap body and restoring the gandap stand. In addition, even if the gandap is damaged, a bulkhead effect occurs, so the entire gandap is not submerged in seawater and maintains a certain buoyancy.

The buoyancy agent 200 is also made of polyethylene material and is combined with the pad. In order to fix the buoyancy material and the padding rod, the padding rods can be placed in pairs at a certain interval and fixed to the fixing part of the buoyancy material. Buoyancy materials supporting the gandapdae may be formed at the upper and lower parts, respectively. The buoyancy material is drum-shaped and has flat upper and lower surfaces, and one or more fixing parts 210 for fixing the rod are formed on the outer circumferential surface of the drum-type. The fixing parts are stainless steel plate bands 220 surrounding the outer circumferential surface of the buoyancy material, and a plurality of fixing parts are formed on the upper and lower parts of the buoyancy material. It can be embedded in the groove and fixed.

The cylindrical outer circumferential surface of the buoyancy material has a groove formed on the outer circumferential surface so that the stainless steel plate strip can be fixed, making on-site work easy. When assembling the buoyancy material and the gandap pole, the fixing part of the buoyancy material has the function of preventing the buoyancy material from moving beyond the protrusion of the gandap pole.

The scaffolding on which the buoyancy material is fixed is a double structure, with an internal frame made of highly durable polyethylene material installed on the inside, and an external frame made of polyethylene material, which is resistant to seawater and has good elasticity, on the outside to prevent bending due to the influence of ocean currents and to maintain rigidity. It is economical because it is improved and made of materials with low production costs. In addition, it is not easily corroded by seawater, so it can be used for a long time when installed in seawater, reducing the time and cost of device replacement.

In addition, if a problem with the buoyancy agent occurs in the field, it can be replaced on site, thereby increasing user convenience and work efficiency. By adjusting the gap between the pad and the buoyancy material according to the variety of cultured seaweed, it can be maintained closely combined with the buoyancy material. By doing so, it can be maintained in a stable and firmly coupled state.

By increasing the lifespan of the device installed in the seaweed farm of the present invention, maintenance costs are reduced for related fishermen, and related industrialists can contribute to profit creation by increasing demand, so it has the potential for industrial use.
