Description

Technical Field

[0001] This invention relates to the field of carbon sequestration technology, and in particular to a forging apparatus for a nickel alloy conveying pipeline for carbon sequestration. Background Technology

[0002] Carbon sequestration is a technology aimed at reducing the concentration of carbon dioxide (CO2) in the atmosphere. It involves the process of capturing, collecting, and safely storing carbon emissions. Specifically, carbon sequestration refers to technologies that replace the direct emission of CO2 into the atmosphere by capturing and safely storing carbon. It aims to stabilize both solid and dissolved forms of carbon, thereby mitigating the trend of global warming.

[0003] During carbon dioxide capture, flue gas typically contains impurities such as sulfur dioxide and moisture. These substances can form acidic condensates during processing, causing corrosion to the delivery pipelines. Therefore, materials with strong corrosion resistance are required to manufacture these pipelines. Nickel alloys, especially nickel-containing stainless steel and super austenitic alloys, are ideal choices for this stage due to their high strength and resistance to crevice and pitting corrosion in acidic solutions. These alloys effectively resist corrosion from wet flue gas, ensuring the smooth operation of the capture process.

[0004] Existing nickel alloy conveying pipe forging equipment involves placing molten billet into a mold, applying pressure to cause plastic deformation, and then removing the formed part from the mold after cooling to obtain a pipe of the desired shape. However, due to the adhesion between the formed part and the mold in the existing technology, the separation efficiency between the formed part and the mold is low. To solve the above problems, we propose a forging equipment for nickel alloy conveying pipes for carbon storage. Summary of the Invention

Cooling mechanisms are provided on both sides of the support. The cooling mechanisms are connected to the containers on the same side and are used to accelerate the cooling of materials in the mold cavity.

[0011] As a further technical solution of the present invention, the cooling mechanism includes a water tank, which is fixedly installed on a support. The water tank contains coolant. A first hose is connected to and fixed at the upper end of the container. The lower end of the first hose is connected to the water tank. The first hose passes through a frame.

[0012] As a further technical solution of the present invention, a heat dissipation vent is provided on one side of the water tank, and two spaced-apart fans are installed on the top of the water tank, with the exhaust end of the fans communicating with the inner cavity of the water tank.

[0017] The forging apparatus for a nickel alloy conveying pipeline for carbon storage proposed in this invention has the following advantages: The forging apparatus for nickel alloy conveying pipes for carbon storage disclosed in this application separates the outer mold from the pipe forming part through hydraulic rods on both sides. The connecting frame is connected to both ends of the outer mold, and the force of the hydraulic rods is applied to both ends of the outer mold. This dual-end force application method can better control the deformation of the material. Due to the more uniform force distribution, the outer mold is less prone to localized excessive deformation or twisting during the pulling process, and it also protects the pipe forming part inside the outer mold.

[0018] The forging apparatus for nickel alloy conveying pipes for carbon storage disclosed in this application, driven by a hydraulic rod, enables the connecting frame to rapidly move the outer mold to separate, thereby quickly removing the pipe forming part from the mold. This design significantly shortens operation time and improves production efficiency. Compared to manual or other complex separation methods, operators only need to control the extension and retraction of the hydraulic rod to achieve mold separation and closure, reducing operational difficulty and labor intensity.

[0019] The forging apparatus for nickel alloy conveying pipes for carbon storage disclosed in this application separates the inner mold from the pipe forming part by rotating the inner mold. Compared with separation methods such as pushing, pulling, and lifting, this method is more labor-saving. Furthermore, the torque applied to different positions of the first friction wheel provides a greater driving force, enabling the inner mold to separate from the pipe forming part quickly. When the torque is insufficient, the second friction wheel can slide relative to the first friction wheel, avoiding forced separation that could cause the stressed structure to break.

[0020] The forging device for the nickel alloy conveying pipeline for carbon storage of this application, by rotating the support at a certain angle around the bushing, the material is subjected to centrifugal force, which helps the material enter the corners or gaps of the mold cavity. Then, by making the material in the mold cavity shake up and down, the material becomes more compact and increases the material density, which helps to eliminate voids and air bubbles inside the material, thereby improving the density and uniformity of the material.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Example 1 Reference Figure 1-8 As shown, a forging device for a nickel alloy conveying pipeline for carbon storage includes a support 1. A movable inner mold 2 is provided on the support 1. Two symmetrically distributed outer molds 3 are arranged outside the inner mold 2. The two outer molds 3 are spliced ​​together, and the support 1, inner mold 2, and two outer molds 3 are combined to form a mold cavity. A connector 4 is rotatably installed through the support 1. The upper end of the connector 4 is connected to the inner mold 2. The inner mold 2 is rotatably installed on the connector 4. A frame 5 is fixedly installed on the support 1. The frame 5 surrounds the inner mold 2 and outer molds 3. A connecting frame 6 is fixedly installed outside the outer mold 3. The connecting frame 6 is fixedly connected to the upper and lower ends of the outer mold 3. The connecting frames 6 are symmetrically distributed on both sides. Hydraulic rods 7 are fixedly installed on both sides of the frame 5. The output ends of the hydraulic rods 7 are fixedly connected to the connecting frames 6 on the same side. A cavity is provided inside the support 1. A driving mechanism is provided inside the support 1. The driving mechanism is connected to the connector 4 and is used to drive the inner mold 2 to rotate.

[0032] The drive mechanism includes a connecting shaft 8, the upper end of which is fixed to the center of the bottom of the connecting member 4. A first friction wheel 9 is fixedly installed at the bottom of the connecting shaft 8. Multiple rotating shafts 10 are rotatably installed inside the support 1, arranged in a circular array around the connecting shaft 8. A second friction wheel 11 is fixedly installed on each rotating shaft 10, and the second friction wheels 11 are in contact with the first friction wheels 9, with transmission between them possible through friction. A driven wheel 12 is fixedly installed at the bottom of each rotating shaft 10. A first motor 13 is fixedly installed inside the support 1, and a driving wheel 34 is fixedly installed at the output shaft end of the first motor 13, meshing with the multiple driven wheels 12.

[0033] The molten material is injected into the mold cavity formed by the combination of support 1, inner mold 2 and two outer molds 3, and after it cools, the separation process is carried out.

[0034] The first motor 13 drives the drive wheel 34 to rotate, which in turn drives multiple driven wheels 12 to rotate. Multiple rotating shafts 10 and second friction wheels 11 rotate synchronously. The multiple second friction wheels 11 apply torque to different points on the first friction wheel 9, causing it to rotate. The first friction wheel 9, connecting piece 4, and inner mold 2 rotate synchronously, thereby separating the inner mold 2 from the pipe forming part. Compared to push-pull or lifting separation methods, this method is more labor-saving, and the torque applied to different positions of the first friction wheel 9 provides greater driving force, enabling rapid separation of the inner mold 2 from the pipe forming part. When the torque is insufficient, the second friction wheels 11 and the first friction wheel 9 can slide relative to each other, preventing forced separation and potential structural breakage.

[0035] By activating the hydraulic rods 7 on both sides, the hydraulic rods 7 drive the connecting frame 6 to move. The connecting frame 6 moves synchronously with the outer mold 3, causing the outer molds 3 on both sides to separate from each other, thereby separating the outer mold 3 from the pipe forming part. The connecting frame 6 is connected to both ends of the outer mold 3, and the force of the hydraulic rods 7 is applied to both ends of the outer mold 3. This double-end force application method can better control the deformation of the material. Due to the more uniform force distribution, the outer mold 3 is less prone to localized excessive deformation or twisting during the pulling process, and it also protects the pipe forming part inside the outer mold 3.

[0036] Driven by the hydraulic rod 7, the connecting frame 6 can quickly move the outer mold 3 to separate, thereby rapidly removing the pipe-shaped part from the mold. This design greatly shortens the operation time and improves production efficiency. Compared with manual or other complex separation methods, operators only need to control the extension and retraction of the hydraulic rod 7 to achieve mold separation and closure, reducing the difficulty of operation and labor intensity.

[0037] Example 2 Reference Figure 5-8As shown, in another preferred embodiment of the present invention, the difference from Embodiment 1 is that a container 14 is fixedly installed on the outer mold 3. Both the outer mold 3 and the container 14 are made of thermally conductive metal. Cooling mechanisms are provided on both sides of the support 1. The cooling mechanisms are connected to the container 14 on the same side and are used to accelerate the cooling of the material in the mold cavity. The cooling mechanism includes a water tank 15, which is fixedly installed on the support 1. The water tank 15 contains coolant. A first hose 16 is connected to and fixed at the upper end of the container 14. The lower end of the first hose 16 is connected to the water tank 15 and passes through the frame 5. A second hose 17 is connected to and fixed at the lower end of the container 14. A pump body 18 is fixedly installed on the water tank 15. The inlet pipe of the pump body 18 is connected to the water tank 15, and the outlet pipe of the pump body 18 is connected to the second hose 17. A heat dissipation vent 19 is opened on one side of the water tank 15. Two spaced-apart fans 20 are installed on the top of the water tank 15. The exhaust end of the fans 20 is connected to the inner cavity of the water tank 15. A temperature measuring device 21 is installed on the water tank 15.

[0038] While waiting for the material in the mold cavity to cool, the coolant in the water tank 15 is injected into the container 14 through the second hose 17 via the pump body 18, and then flows back into the water tank 15 through the first hose 16. This circulating coolant quickly removes heat from the outer mold 3, thus accelerating the cooling of the material in the mold cavity. The fan 20 further accelerates the heat dissipation efficiency of the coolant in the water tank 15, while the heat from the coolant is discharged through the heat dissipation vent 19. The temperature of the coolant is measured by the temperature measuring device 21. If the coolant temperature is too high, the forging operation is stopped, and work resumes only after the coolant temperature has decreased.

[0039] The support 1 has a base 22 at its bottom, with an annular groove 23 at its upper end. Multiple rolling balls 24 are mounted on the bottom of the support 1, all within the annular groove 23. A bottom shaft 25 is fixed at the center of the bottom of the support 1. A bushing 26 is rotatably mounted on the top of the base 22. The lower end of the bottom shaft 25 is inserted into the bushing 26. Spline grooves 27 are formed on both sides of the bushing 26. Splines 28 are fixedly mounted on both sides of the bottom shaft 25, and the splines 28 are slidably positioned within the spline grooves 27 on the same side. Multiple elastic elements 29 arranged in a circular array are provided between the bushing 26 and the base 22, with both ends of the elastic elements 29 fixedly connected to the bushing 26 and the base 22, respectively. A spring 30 is fixed inside the bushing 26. The upper end of the spring 30 is fixed to the bottom of the bottom shaft 25. A rack 31 is fixedly installed on the bottom shaft 25. A second motor 32 is fixedly installed at the bottom of the support 1. An incomplete gear 33 is fixedly installed at the output shaft end of the second motor 32. The incomplete gear 33 meshes with the rack 31.

[0040] After the molten material is injected into the mold cavity, the inner mold 2 and outer mold 3 on the support 1 can be rotated synchronously by rotating the support 1 around the bushing 26 at a certain angle, not exceeding ninety degrees. As the material inside the mold cavity rotates, it is subjected to centrifugal force, which helps the material enter the corners or gaps of the mold cavity. During the rotation, the elastic element 2 deforms. After the support 1 is released, the elastic force of the elastic element 2 drives the support 1 to return to its original position. Then, the second motor 32 drives the incomplete gear 33 to rotate. The incomplete gear 33 drives the rack 31 to move down. The rack 31, the bottom shaft 25 and the support 1 move down synchronously, and the spring 30 is compressed. When the incomplete gear 33 separates from the rack 31, the spring 30 drives the support 1 to return to its original position. This cycle repeats, which makes the material inside the mold cavity shake up and down, making the material more compact and increasing its density.

[0041] Working principle: By injecting molten material into the mold cavity formed by the combination of support 1, inner mold 2, and two outer molds 3, after the molten material is injected into the mold cavity, the support 1 is rotated at a certain angle (not exceeding 90 degrees) around the bushing 26, which drives the inner mold 2 and outer mold 3 on the support 1 to rotate synchronously. By rotating the material in the mold cavity, the material is subjected to centrifugal force, which helps the material enter the corners or gaps of the mold cavity. During the rotation, the elastic element 2 deforms, and after releasing the support 1, the elastic force of the elastic element 2 drives the support 1 to return to its original position. Then, the second motor 32 drives the incomplete gear 33 to rotate, and the incomplete gear 33 drives the rack 31 to move down. The rack 31, the bottom shaft 25 and the support 1 move down synchronously, and the spring 30 is compressed. When the incomplete gear 33 separates from the rack 31, the spring 30 drives the support 1 to return to its original position. This reciprocating cycle allows the material in the mold cavity to shake up and down, making the material more compact and increasing its density.

[0042] Next, while waiting for the material in the mold cavity to cool, the coolant in the water tank 15 is injected into the container 14 through the second hose 17 via the pump body 18, and then flows back into the water tank 15 through the first hose 16. This circulating coolant quickly removes heat from the outer mold 3, thus accelerating the cooling of the material in the mold cavity. The fan 20 further accelerates the heat dissipation efficiency of the coolant in the water tank 15, while the heat from the coolant is discharged through the heat dissipation vent 19. The temperature of the coolant is measured by the temperature measuring device 21. If the coolant temperature is too high, the forging operation is stopped, and work resumes only after the coolant temperature has decreased.

[0043] After the material in the mold cavity has cooled, the first motor 13 drives the drive wheel 34 to rotate, which in turn drives multiple driven wheels 12 to rotate. Multiple rotating shafts 10 and second friction wheels 11 rotate synchronously. The multiple second friction wheels 11 apply torque to different points of the first friction wheel 9, causing it to rotate. The first friction wheel 9, connecting piece 4, and inner mold 2 rotate synchronously, thereby separating the inner mold 2 from the pipe forming part. Subsequently, by activating the hydraulic rods 7 on both sides, the hydraulic rods 7 drive the connecting frame 6 to move. The connecting frame 6 moves synchronously with the outer mold 3, causing the outer molds 3 on both sides to separate, thus separating the outer mold 3 from the pipe forming part.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
