Description

Technical Field

[0001] This invention relates to the field of non-metallic hydrogen transport composite pipe manufacturing technology, and in particular to a non-metallic flexible hydrogen transport pipe and its preparation apparatus. Background Technology

[0002] With the rapid development of the hydrogen energy industry, safe and efficient hydrogen transportation pipelines have become one of the key technologies. Non-metallic flexible hydrogen pipelines, due to their advantages such as light weight, corrosion resistance, and good flexibility, have gradually become a research hotspot in the field of hydrogen transportation. Currently, non-metallic flexible hydrogen pipelines typically employ a multi-layer composite structure, including an inner lining layer, a reinforcing layer, and an outer protective layer, and are continuously manufactured through processes such as extrusion, fiber winding, and heat curing.

[0003] After the pipeline is manufactured, long-distance flexible hydrogen transport pipes are typically rolled into coils for easy transportation and storage. Existing rolling devices use manual assistance to guide the winding direction of the pipes, achieving layer-by-layer arrangement of the pipes on the coil.

[0004] Therefore, how to achieve automatic directional control of non-metallic flexible hydrogen transport pipes during the rolling process, and improve the regularity and automation level of the rolling, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a non-metallic flexible hydrogen transport pipe and its preparation device, which solves the technical problem in the prior art where the winding device guides the winding direction of the pipe with manual assistance.

[0006] To achieve the above objectives, the present invention provides a non-metallic flexible hydrogen transport tube manufacturing apparatus, comprising an extruder, a fiber winding machine, a laser heater, a heating chamber, and a flexible hydrogen transport tube winding mechanism connected together. The non-metallic flexible hydrogen transport tube includes an inner liner, a reinforcing layer, and an outer protective layer. The inner liner is extruded into a tube by the extruder and then enters the fiber winding machine to wind fibers onto the surface of the inner liner. The laser heater preheats the fibers, which are then heated again by the heating chamber. The extruder extrudes and covers the outer protective layer onto the outer surface of the reinforcing layer. The complete non-metallic flexible hydrogen transport tube is wound by the flexible hydrogen transport tube winding mechanism.

[0007] Preferably, the non-metallic flexible hydrogen transport tube is conveyed to the flexible hydrogen transport tube winding mechanism on the support frame, and the bottom of the non-metallic flexible hydrogen transport tube contacts the bottom of the arc-shaped inner cavity of the support frame.

[0008] Preferably, a groove is provided on the right output end of the support frame, a fixing plate is fixedly connected to the top of the support frame, the bottom of the fixing plate is fixed to the fixed end of the electric telescopic rod, the movable end of the electric telescopic rod is fixed to the blade, and the blade is located directly above the groove.

[0009] Preferably, the bottom of the support frame is arc-shaped, the groove is also arc-shaped, the bottom of the blade is also arc-shaped, and the bottom of the blade matches the shape of the groove.

[0010] Preferably, a fixing plate two is fixedly connected to the outer wall of the support frame. The fixing plate two is fixed to the fixed end of the electric telescopic rod two. The movable end of the electric telescopic rod two passes through the fixing plate two and is fixed to the side wall of the ring. The non-metallic flexible hydrogen transport pipe passes through the ring and is rolled by the flexible hydrogen transport pipe rolling mechanism. The second electric telescopic pole is set horizontally, and the extension and retraction direction of the second electric telescopic pole is perpendicular to the movement direction of the non-metallic flexible hydrogen transport pipe.

[0011] Preferably, the flexible hydrogen transport tube winding mechanism includes a base, a connecting plate, a connecting plate, and a motor. The bottom of the base is set on the ground, the motor is fixedly connected to one side wall of the base, the output end of the motor is fixed to the center of the connecting plate, and two arc-shaped connecting plates are fixedly connected to the side wall of the connecting plate. The connecting plates are arranged opposite each other and form a circular shape. A gap is provided between the two connecting plates, and one end of the non-metallic flexible hydrogen transport tube can be inserted into the gap. The electric telescopic rod drives the ring to move, which in turn drives the non-metallic flexible hydrogen transport pipe to move, thereby driving the non-metallic flexible hydrogen transport pipe to wind layer by layer on the connecting plate.

[0012] Preferably, the size of the gap is smaller than the outer diameter of the non-metallic flexible hydrogen transport pipe.

[0013] Preferably, the arc-shaped connecting plate extends along the length direction of the electric telescopic rod II.

[0014] Preferably, the electric telescopic rod one, the electric telescopic rod two, and the motor are all electrically connected to the controller.

[0015] Preferably, a method for operating a non-metallic flexible hydrogen transport pipe manufacturing apparatus includes the following steps: Step 1: Inner liner extrusion molding. The extruder extrudes non-metallic materials to form a tubular structure, which serves as the inner liner of the non-metallic flexible hydrogen transport pipe. Step 2: Reinforcing layer fiber winding. The formed inner lining layer is conveyed to the fiber winding machine, and fiber material is evenly wound on the outer surface of the inner lining layer. The laser heater preheats the fiber to improve the bonding performance between the fiber and the matrix, thus forming the reinforcing layer. Step 3: Heating and curing. The preheated pipes continue to enter the heating chamber for heating treatment, so that the reinforcing layer material can be fully cured or fused together. Step 4: Outer protective layer coating. After heating and curing, the pipe is put back into the extruder to extrude the outer protective layer material onto the outer surface of the reinforcing layer, forming a complete non-metallic flexible hydrogen transport pipe. Step 5: Rolling and forming. The complete non-metallic flexible hydrogen transport tube is guided by the support frame into the flexible hydrogen transport tube rolling mechanism. The end of the non-metallic flexible hydrogen transport tube is clamped in the gap between the two connecting plates and the non-metallic flexible hydrogen transport tube is set near the connecting plate. Step 6: The controller controls the motor to drive the connecting disc and connecting plate to rotate. The non-metallic flexible hydrogen transport tube is wound around the connecting plate once. Then, the electric telescopic rod extends to control the movement of the ring, so that the non-metallic flexible hydrogen transport tube moves in the positive x-axis direction and is wound around the connecting plate to complete the second turn of winding. Continue to control the electric telescopic rod to extend to complete one layer of winding on the connecting plate. Step 7: When the non-metallic flexible hydrogen delivery tube reaches the end of the connecting plate and needs to return to the second layer of winding, the electric telescopic rod 2 is controlled to shorten the control ring and move, so that the non-metallic flexible hydrogen delivery tube moves in the negative x-axis direction and is wound on the connecting plate. The electric telescopic rod 2 is controlled to shorten again to complete the second layer of winding on the connecting plate. When the non-metallic flexible hydrogen delivery pipe reaches the position of the connecting plate and needs to be wound back to the third layer, the electric telescopic rod II controls the extension and movement of the ring, and this process is repeated. Step 8, Cutting Control: During the rolling process, when cutting is required, activate the electric telescopic rod to drive the blade down to the groove and cut the pipe.

[0016] The non-metallic flexible hydrogen transmission pipe includes an inner lining, a reinforcing layer, and an outer protective layer. The inner lining is made of PE or PA material; the reinforcing layer is made of carbon fiber tape, glass fiber tape, or aramid fiber tape prepreg; and the outer protective layer is made of PE or PA material.

[0017] The advantages and positive effects of the non-metallic flexible hydrogen transport pipe preparation device and method described in this invention are as follows: 1. By setting up an electric telescopic rod II and a ring, and cooperating with the controller to precisely control the axial movement direction and distance of the pipeline, the non-metallic flexible hydrogen transport pipe can automatically complete the orderly winding of layer by layer and circle by circle on the connecting plate. When it is necessary to change the winding layer, the electric telescopic rod II automatically switches the extension direction, realizing the reciprocating winding of the pipeline on the connecting plate without the need for manual adjustment of the direction, which significantly reduces the complexity of operation and labor intensity.

[0018] 2. The controller is set according to the length direction of the connecting plate, and controls the extension or shortening of the electric telescopic rod two, so that the pipeline automatically turns back to perform the next layer of winding after completing one layer of winding. It can repeatedly perform multi-layer winding to meet the winding requirements of non-metallic flexible hydrogen transmission pipes of different lengths, and improve the versatility and automation level of the equipment.

[0019] 3. An electric telescopic rod and an arc-shaped blade that matches the groove are installed on the support frame. When a fixed-length cut is required during the rolling process, the controller can start the blade to automatically fall and cut the pipe. There is no need to configure a separate cutting station, which reduces the equipment footprint and process flow time, and is conducive to forming a continuous and automated integrated production line for hydrogen pipeline preparation, rolling and cutting.

[0020] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0031] A fixing plate 2 is fixedly connected to the outer wall of the support frame 9. The fixing plate 2 is fixed to the fixed end of the electric telescopic rod 2 14. The movable end of the electric telescopic rod 2 14 passes through the fixing plate 2 and is fixed to the side wall of the ring 15. The non-metallic flexible hydrogen transport pipe 10 passes through the ring 15 and is rolled by the flexible hydrogen transport pipe rolling mechanism 8.

[0032] The electric telescopic rod 214 is set horizontally, and the telescopic direction of the electric telescopic rod 214 is perpendicular to the moving direction of the non-metallic flexible hydrogen transmission pipe 10.

[0033] Specifically, the extension length and time of the electric telescopic rod 14 are controlled by a controller, which is related to the size and number of layers of the non-metallic flexible hydrogen transport pipe 10 and the outer diameter of the connecting plate 18. The controller's control system is programmed.

[0034] The flexible hydrogen transport tube winding mechanism 8 includes a base 16, a connecting plate 20, a connecting plate 18, and a motor 17. The bottom of the base 16 is set on the ground. The motor 17 is fixedly connected to one side wall of the base 16. The output end of the motor 17 is fixed to the center of the connecting plate 20. Two arc-shaped connecting plates 18 are fixedly connected to the side wall of the connecting plate 20. The connecting plates 18 are arranged opposite each other and form a circular shape. A gap 19 is provided between the two connecting plates 18, and one end of the non-metallic flexible hydrogen transport tube 10 can be inserted into the gap 19.

[0035] The electric telescopic rod 14 drives the ring 15 to move, which in turn drives the non-metallic flexible hydrogen transport pipe 10 to move, thereby driving the non-metallic flexible hydrogen transport pipe 10 to wind layer by layer on the connecting plate 18.

[0036] The size of the gap 19 is smaller than the outer diameter of the non-metallic flexible hydrogen transport tube 10.

[0037] The arc-shaped connecting plate 18 extends along the length direction of the electric telescopic rod 14 in the telescopic direction.

[0038] Electric telescopic pole 11, electric telescopic pole 2 14 and motor 17 are all electrically connected to the controller.

[0039] A method for operating a non-metallic flexible hydrogen transport tube 10 preparation device includes the following steps: Step 1: The inner liner 1 is extruded and formed by the extruder 4. The extruder 4 extrudes the non-metallic material to form a tubular structure, which serves as the inner liner 1 of the non-metallic flexible hydrogen transport pipe 10.

[0040] Step 2: Fiber winding for reinforcing layer 2. The formed inner lining layer 1 is conveyed to the fiber winding machine 5, and fiber material is evenly wound on the outer surface of the inner lining layer 1. The laser heater 6 preheats the fiber to improve the bonding performance between the fiber and the matrix, thus forming the reinforcing layer 2.

[0041] Step 3: Heating and curing. The preheated pipe continues to enter the heating box 7 for heating treatment, so that the reinforcing layer 2 material is fully cured or melted together.

[0042] Step 4: The outer protective layer 3 is wrapped around the pipe after heating and curing. The pipe is then extruded into the extruder 4 to extrude the outer protective layer 3 material onto the outer surface of the reinforcing layer 2, forming a complete non-metallic flexible hydrogen transport pipe 10.

[0043] Step 5: Rolling and forming. The complete non-metallic flexible hydrogen transport tube 10 is guided by the support frame 9 and enters the flexible hydrogen transport tube rolling mechanism 8. The end of the non-metallic flexible hydrogen transport tube 10 is snapped into the gap 19 between the two connecting plates 18, and the non-metallic flexible hydrogen transport tube 10 is positioned near the connecting plate 20.

[0044] Step six: The controller controls motor 17 to drive connecting disc 20 and connecting plate 18 to rotate. The non-metallic flexible hydrogen delivery tube 10 is wound around the connecting plate 18 once. Then, the electric telescopic rod 14 extends to control the movement of ring 15, causing the non-metallic flexible hydrogen delivery tube 10 to move in the positive x-axis direction, while simultaneously winding around the connecting plate 18, completing the second turn. The electric telescopic rod 14 continues to extend to complete one more turn of winding on the connecting plate 18.

[0045] Step 7: When the non-metallic flexible hydrogen delivery tube 10 reaches the end of the connecting plate 18 and needs to return to the second layer of winding, the electric telescopic rod 2 14 controls the shortening control ring 15 to move, so that the non-metallic flexible hydrogen delivery tube 10 moves in the negative x-axis direction and is wound on the connecting plate 18. Continue to control the electric telescopic rod 2 14 to shorten, and complete the second layer of winding on the connecting plate 18.

[0046] When the non-metallic flexible hydrogen delivery pipe 10 reaches the position of the connecting plate 20 and needs to return to the third layer for winding, the electric telescopic rod 14 controls the extension and movement of the control ring 15, and so on.

[0047] Step 8, Cutting control: During the rolling process, when cutting is required, start the electric telescopic rod 11 to drive the blade 12 to fall to the groove 13 and cut the pipe.

[0048] Specifically, after the non-metallic flexible hydrogen transport tube 10 is wound, it is bundled or film-coated and then manually removed from the connecting plate 18.
