Abstract
Description
Technical Field
[0001] This invention relates to the field of wind turbine blade production technology, specifically to a processing device and method for wind turbine blade materials. Background Technology
[0002] Currently, rigid cross-linked PVC foam, PU foam, or PET foam are mostly used for the custom-shaped parts of wind turbine blades. When processing foam, foam wedges are often prepared by mixing materials using a foaming machine. A foaming machine, also known as a foam generator, is a device that produces foam by adding a foaming agent to an aqueous solution of a certain concentration. Foaming machines are divided into high-pressure foaming machines and low-pressure foaming machines. High-pressure foaming machines use high-pressure air to push liquid foaming agent into a mixer. After the liquid foaming agent in the mixer is mixed with the ambient air on the spraying surface, it is sprayed out by the pressure of the high-pressure air to form a uniform foam layer.
[0003] In the prior art, such as Chinese Patent No. CN216609781U, a high-pressure foaming machine is disclosed. This utility model includes a foaming machine body, in which a stirrer is rotatably installed, and a drive motor is installed on the foaming machine body. The drive motor drives the stirrer to work through a speed adjustment structure. When the whole device is working, the drive motor works, and the stirrer is controlled to work through the speed adjustment structure. The speed adjustment structure can control and adjust the stirring speed of the stirrer to achieve the adjustment of the stirrer's working speed according to the actual situation. The auxiliary structure can adjust the tension of the conveyor belt in real time, thereby making the whole device work stably.
[0004] In applications, high-pressure foaming machines produce foam with higher strength and greater durability. Wind turbine blades foamed using high-pressure foaming machines have better quality. However, in current technologies, the mixing ratio of foaming agent and air in commonly used high-pressure foaming machines is poor, resulting in insufficient foam density. Therefore, the foaming precision and efficiency need to be further improved.
[0005] Therefore, we propose a processing device and method for wind turbine blade materials to solve the problems mentioned above. Summary of the Invention

[0013] Preferably, a support mechanism is rotatably sleeved between the outer surfaces of the two rotating blocks.

[0014] Preferably, the top of the mounting bracket is provided with a forward and reverse motor, and the output shaft of the forward and reverse motor is fixedly connected to the outer surface of one of the rotating blocks.
[0015] Preferably, a first valve is provided on the outer surface of the feed inlet, and a second valve is provided on the outer surface of the discharge outlet.
[0016] A method for using a wind turbine blade material processing device includes the following steps:
[0017] S1. First, prepare the foaming agent, which is a premix of polyols RF4111, PS3152, DPG, TCPP, H2O, Polycat8 and L6900, and a black material PM200 with an isocyanate index of 120 and a free bubble density of 80 kg / m3. It is injected into the foaming cylinder through the feed port. At this time, one end of the feed port of the foaming cylinder is facing down. Then, use an air pump to pump air into the air inlet pipe at high pressure. The air is quickly sprayed out from multiple oblique air outlets and mixed with the foaming agent at high pressure to form foam.
[0018] S2. After the foaming agent is completely foamed under high-pressure air injection, the flipping mechanism is started to flip the foaming cylinder 180° so that the discharge port of the foaming cylinder faces downward. At this time, the servo motor is started so that the servo motor drives the mixing mechanism to start operating.
[0019] S3. Under the steering action of the transmission mechanism, the first separation chamber and the second separation chamber can rotate in opposite directions. The foam with small bubble volume continuously impacts and breaks with the crushing plate in the first separation chamber. The foam with small bubble volume is thrown out through the first bubble outlet in the first separation chamber and reaches the second separation chamber. It is then thrown out through the second bubble outlet with a smaller inner diameter and reaches the bottom of the foaming cylinder. After multi-layer mixing, the foam foam produced under high pressure has a higher density.
[0020] S4. Based on the size of the foam wedge mold cavity, the high-density foam output from the outlet is overfilled with 120%. 180g of mixed foaming material is quantitatively poured into the center of the mold after opening the mold. The pouring time is 2 seconds and the mold temperature is 40℃. After pouring, the mold is closed for 3 minutes and the wind turbine blade sample is taken out. Due to the skin formation on the surface, the surface is polished with a grinder to facilitate subsequent bonding with fiberglass.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] 1. In use, firstly, the foaming agent is injected into the foaming cylinder through the feed inlet. At this time, one end of the feed inlet of the foaming cylinder is facing downwards. Then, an air pump is used to inject high-pressure air into the air inlet pipe. The air is quickly sprayed out from multiple oblique air outlets and mixed with the foaming agent under high pressure to form foam. After the foaming agent is completely formed into foam under high-pressure air injection, the flipping mechanism is activated to flip the foaming cylinder 180°. Under the steering action of the transmission mechanism, the first separation chamber and the second separation chamber can rotate in opposite directions. The small bubbles of different sizes in the foam pass through the first separation chamber and the second separation chamber in sequence through rapid rotation. After multi-layer mixing, the foam produced by high pressure has a higher density and the foaming agent and air are mixed more thoroughly. This solves the problem that the mixing ratio of foaming agent and air in the current common high-pressure foaming machines is poor, which makes it necessary to further improve the foaming accuracy and foaming efficiency.
[0023] 2. During use, the rotation of the first separation chamber drives the rotation of the active hollow gear. The active hollow gear meshes with and drives the rotation of the steering gear, which in turn drives the rotation of the driven hollow gear. This achieves the first and second separation chambers rotating in opposite directions at the same speed, allowing the mixing mechanism to rotate around the hollow tube. By starting the servo motor, the output shaft of the servo motor rotates, thereby achieving the rotation of the mixing mechanism. The combination of the soft sheet and the limiting strip can effectively prevent the foam generated inside the foaming cylinder from flowing into the hollow tube from the air outlet.
[0024] 3. During use, the feed inlet should be facing downwards during feeding to prevent the foaming liquid from penetrating the first and second separation chambers before it comes into contact with air and generates bubbles. After foam is generated, the foaming cylinder mechanism should be flipped so that the discharge outlet faces downwards to start the mixing mechanism. By starting the forward and reverse motors, the output shafts of the motors rotate, thereby driving the flipping mechanism to flip. After feeding, close the first valve to prevent the generated foam from overflowing from the feed inlet. At the same time, open the second valve to allow excess air to be discharged from the foaming cylinder, preventing excessive pressure inside the foaming cylinder. After flipping the foaming cylinder, close the second valve. The second valve only needs to be opened when discharging foam. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] Please see Figure 1-9This invention provides a technical solution: a processing device for wind turbine blade materials, comprising: a foaming cylinder mechanism 3, the foaming cylinder mechanism 3 including a foaming cylinder body 301, an inlet 303 fixedly connected to the outer surface of the foaming cylinder body 301 near the top, and an outlet 305 fixedly connected to the outer surface of the foaming cylinder body 301 near the bottom; an air jetting mechanism 4, the air jetting mechanism 4 including a hollow tube 401, the outer surface of the hollow tube 401 having multiple oblique air outlets 402 near the top; and a mixing mechanism 5, the mixing mechanism 5 including an installation tube 501, the bottom of the installation tube 501 being fixedly mounted with multiple first fixing rods 502, and a first separation chamber 503 fixedly mounted between the bottom ends of the multiple first fixing rods 502. A first bubble outlet hole 504 is provided on the outer surface of a separation chamber 503. A transmission mechanism 506 is fixedly installed at the bottom of the first separation chamber 503. A second fixing rod 507 is fixedly installed at the bottom of the transmission mechanism 506. A second fixing tube 511 is fixed between the bottom ends of the second fixing rods 507. A second separation chamber 509 is fixedly connected to the bottom of the second fixing tube 511. A second bubble outlet hole 510 is provided on the outer surface of the second separation chamber 509. A third fixing rod 512 is fixedly installed at the bottom of the second separation chamber 509. A third fixing tube 514 is fixedly installed between the bottom ends of the third fixing rods 512. A multiple stirring rod 513 is fixed on the outer surface of the third fixing tube 514.
[0038] like Figure 4-7 As shown, multiple crushing plates 6 are fixed to the inner wall of the foaming cylinder 301. The transmission mechanism 506 includes a driving hollow gear 5061, a steering gear 5062 meshing with the outer surface of the driving hollow gear 5061, a driven hollow gear 5066 meshing with the outer surface of the steering gear 5062, a support rod 5063 rotatably embedded inside the steering gear 5062, an anti-detachment block 5065 fixedly installed at one end of the support rod 5063, two stops 5064 fixedly fixed on the outer surface of the support rod 5063 near the steering gear 5062, and the other end of the support rod 5063 fixedly connected to the inner wall of the foaming cylinder 301. The rotation of the first separation chamber 503 drives the rotation of the driving hollow gear 5061, the driving hollow gear 5061 meshes with and drives the rotation of the steering gear 5062, and the steering gear 5062 drives the driven hollow gear 5066 to rotate, thereby realizing that the first separation chamber 503 and the second separation chamber 509 rotate in opposite directions at the same speed.
[0039] like Figure 4-6As shown, the mounting tube 501, the first separation chamber 503, the first fixing tube 505, the driving hollow gear 5061, the driven hollow gear 5066, the second separation chamber 509, the second fixing tube 511, and the third fixing tube 514 are all movably sleeved on the outside of the hollow tube 401. The mounting tube 501 movably extends through to the outside of the foaming cylinder 301, so that the mixing mechanism 5 can rotate around the hollow tube 401.
[0040] like Figure 4 As shown, a servo motor 508 is mounted on the top of the foaming cylinder 301 via an auxiliary frame. The output shaft of the servo motor 508 is fixedly connected to the top of the mounting tube 501. By starting the servo motor 508, the output shaft of the servo motor 508 rotates, thereby driving the mounting tube 501 to rotate, thus realizing the rotation of the mixing mechanism 5.
[0041] like Figure 8-9 As shown, each air outlet 402 has a combined soft sheet 403 pasted on its inner wall, and three limiting strips 404 are fixedly installed on the inner wall of each air outlet 402. An air inlet pipe 405 is fixedly installed at the bottom end of the hollow tube 401. The bottom end of the hollow tube 401 is fixedly inserted through the foaming cylinder 301 to the outside. After air is injected into the hollow tube 401 through the air inlet pipe 405, it will break open the combined soft sheet 403 and spray out from the air outlet 402. Conversely, the limiting strips 404 will block the combined soft sheet 403 from opening in the opposite direction, effectively preventing the foam generated in the foaming cylinder 301 from flowing into the hollow tube 401 from the air outlet 402.
[0042] like Figure 1-3 As shown, a flipping mechanism 2 is fixedly installed on both sides of the foaming cylinder 301. Each flipping mechanism 2 includes a rotating block 201. Two connecting plates 202 are fixedly installed on opposite sides of the two rotating blocks 201. A fixing frame 203 is fixedly connected between the outer surfaces of each pair of connecting plates 202. The two ends of the two fixing frames 203 are fixedly connected to the two sides of the foaming cylinder 301 respectively. The foaming cylinder mechanism 3 can be flipped through the flipping mechanism 2. When feeding, the feed port 303 is turned downward to prevent the foaming liquid from penetrating the first separation chamber 503 and the second separation chamber 509 before it comes into contact with air and generates bubbles. After foam is generated, the foaming cylinder mechanism 3 is flipped again so that the discharge port 305 is turned downward, and the operation of the mixing mechanism 5 can begin.
[0043] like Figure 1-2 As shown, a support mechanism 1 is rotatably sleeved between the outer surfaces of the two rotating blocks 201. The support mechanism 1 includes a support frame 101. Reinforcing plates 102 are fixedly connected to both sides of the support frame 101 near the bottom. An mounting frame 103 is fixedly installed on one side of the support frame 101. The flipping mechanism 2 and the foaming cylinder mechanism 3 are supported by the support frame 101. The reinforcing plate 102 is a triangular plate to prevent the equipment from tipping over.
[0044] like Figure 1-3 As shown, a forward and reverse motor 204 is provided on the top of the mounting bracket 103. The output shaft of the forward and reverse motor 204 is fixedly connected to the outer surface of one of the rotating blocks 201. By starting the forward and reverse motor 204, the output shaft of the forward and reverse motor 204 rotates, thereby driving the flipping mechanism 2 to flip.
[0045] like Figure 1-2 As shown, a first valve 302 is provided on the outer surface of the feed inlet 303, and a second valve 304 is provided on the outer surface of the discharge outlet 305. After feeding, the first valve 302 is closed to prevent the generated foam from overflowing from the feed inlet 303. At the same time, the second valve 304 is opened to allow excess air in the foaming cylinder 301 to be discharged, preventing excessive pressure in the foaming cylinder 301. After the foaming cylinder 301 is turned over, the second valve 304 is closed. The second valve 304 is only needed to be opened when discharging foam.
[0046] A method for using a wind turbine blade material processing device includes the following steps:
[0047] S1. First, prepare the foaming agent, which is a premix of polyols RF4111, PS3152, DPG, TCPP, H2O, Polycat8 and L6900, and a black material PM200 with an isocyanate index of 120 and a free bubble density of 80 kg / m3. It is injected into the foaming cylinder 301 through the feed port 303. At this time, one end of the feed port 303 of the foaming cylinder 301 is facing down. Then, use an air pump to pump air into the air inlet pipe 405 at high pressure. The air is quickly sprayed out from multiple inclined air outlets 402 and mixed with the foaming agent at high pressure to form foam.
[0048] S2. After the foaming agent is completely foamed under high-pressure air injection, the flipping mechanism 2 is started to flip the foaming cylinder 301 180° so that one end of the discharge port 305 of the foaming cylinder 301 faces downward. At this time, the servo motor 508 is started so that the servo motor 508 drives the mixing mechanism 5 to start operating.
[0049] S3. Under the steering action of the transmission mechanism 506, the first separation chamber 503 and the second separation chamber 509 can rotate in opposite directions. The foam with small bubble volume continuously impacts and breaks with the crushing plate 6 in the first separation chamber 503. The foam with small bubble volume is thrown out of the first bubble outlet 504 on the first separation chamber 503, reaches the second separation chamber 509, and is thrown out again through the second bubble outlet 510 with a smaller inner diameter, reaching the bottom of the foaming cylinder 301. After multi-layer mixing, the foam foam material produced under high pressure has a higher density.
[0050] S4. Based on the size of the cavity of the foam wedge mold, the high-density foam output from outlet 305 is overfilled with 120%. 180g of mixed foaming material is quantitatively poured into the center of the mold after opening the mold. The pouring time is 2 seconds and the mold temperature is 40℃. After pouring, the mold is closed for 3 minutes and the wind turbine blade sample is taken out. Due to the skin formation on the surface, the surface is polished with a grinder to facilitate subsequent bonding with fiberglass.
[0051] In this invention, during use, firstly, a foaming agent is prepared, namely, a premix of polyols RF4111, PS3152, DPG, TCPP, H2O, Polycat8, and L6900, with PM200 as the black component, an isocyanate index of 120, and a free bubble density of 80 kg / m3. The first valve 302 is opened, and the prepared foaming agent is injected into the foaming cylinder 301 through the inlet 303. At this time, one end of the inlet 303 of the foaming cylinder 301 faces downwards, and one end of the air inlet pipe 405 faces upwards. Simultaneously, an air pump is used to pressurize the air inlet pipe 405, and the air is forced into the hollow tube 401. The outlet slant 402 is evenly distributed between the first separation chamber 503 and the mounting pipe 501. Air is rapidly ejected from multiple inclined air outlets 402, mixing with the foaming agent under high pressure to form foam. At this time, the combined flexible sheet 403 blocks the foam outside the inclined air outlets 402, preventing it from entering the hollow tube 401. After the foaming agent is completely formed into foam under high-pressure air injection, the forward and reverse motor 204 is activated, causing its output shaft to rotate. This, in turn, drives the tilting mechanism 2 to rotate, tilting the foaming cylinder 301 180° so that one end of its outlet 305 faces downwards. Simultaneously, the servo motor 508 is activated, causing the mixing mechanism 5 to start operating. The output shaft of the servo motor 508 then rotates the mounting tube 501. This causes the mounting tube 501 to simultaneously drive the first fixing rod 502, the first fixing tube 505, the first separation chamber 503, and the driving hollow gear 5061 to rotate. Smaller bubbles continuously impact and break against the crushing plate 6 within the first separation chamber 503. These smaller bubbles are then ejected from the first bubble outlet 504 in the first separation chamber 503 and reach the second separation chamber 509. Under the meshing action of the steering gear 5062, the driven hollow gear 5066 rotates in the opposite direction to the driving hollow gear 5061. The driving hollow gear 5061 simultaneously drives the second fixing rod 507, the second fixing tube 511, the second separation chamber 509, the third fixing rod 512, the third fixing tube 514, and the stirring rod 51. 3. Rotation causes the foam with increased density to reach the second separation chamber 509, and then it is thrown out through the second bubble outlet 510 with a smaller inner diameter, reaching the bottom of the foaming cylinder 301. The stirring rod 513 at the bottom continuously stirs, which can effectively prevent foam sedimentation. After multi-layer mixing, the foam produced under high pressure has a higher density. According to the size of the foam wedge mold cavity, the high-density foam output from the outlet 305 is overfilled with 120%. 180g of mixed foaming material is quantitatively poured into the center of the mold for 2 seconds. The mold temperature is 40℃. After pouring, the mold is closed for 3 minutes and the wind turbine blade sample is taken out. Due to the skin phenomenon on the surface, a grinder is used to grind the surface to facilitate subsequent bonding with fiberglass.

9. A method of using a wind turbine blade material processing device, characterized in that, A processing apparatus using the wind turbine blade material according to any one of claims 1-8, comprising the following steps: S1. First, prepare the foaming agent, namely, the polyol is premixed with RF4111, PS3152, DPG, TCPP, H2O, Polycat8 and L6900, the black material is PM200, the isocyanate index is 120, the free bubble density is 80kg / m3, and it is injected into the foaming cylinder (301) through the feed port (303). At this time, one end of the feed port (303) of the foaming cylinder (301) is facing down, and then the air pump is used to pump air into the air inlet pipe (405) under high pressure. The air is quickly sprayed out from multiple air outlets (402) and mixed with the foaming agent under high pressure to form foam. S2. After the foaming agent is completely formed into foam under high-pressure air injection, the flipping mechanism (2) is started to flip the foaming cylinder (301) 180° so that one end of the outlet (305) of the foaming cylinder (301) is facing down. At this time, the servo motor (508) is started so that the servo motor (508) drives the mixing mechanism (5) to start operating. S3. Under the steering action of the transmission mechanism (506), the first separation chamber (503) and the second separation chamber (509) can rotate in opposite directions. The foam with small bubble volume continuously impacts and breaks with the crushing plate (6) in the first separation chamber (503). The foam with small bubble volume is thrown out through the first bubble outlet (504) on the first separation chamber (503), reaches the second separation chamber (509), and is thrown out through the second bubble outlet (510) with a smaller inner diameter, reaching the bottom of the foaming cylinder (301). After multi-layer mixing, the foam foam produced under high pressure has a higher density. S4. According to the size of the cavity of the foam wedge mold, the high-density foam output from the outlet (305) is overfilled with 120%. 180g of mixed foaming material is poured into the center of the mold after opening the mold. The pouring time is 2 seconds and the mold temperature is 40℃. After pouring, the mold is closed for 3 minutes and the wind turbine blade sample is taken out. Since there is a skin on the surface, the surface is polished with a grinder to facilitate subsequent bonding with fiberglass.
