Description

Technical Field

[0001] The present invention relates to the technical field of material recycling, and particularly to a recycling device for carbon fiber composite materials of wind turbine blades. Background Art

[0002] As a core component of a wind turbine generator, the basic function of a wind turbine blade is to capture wind energy and convert it into mechanical energy. With the development of wind power generation towards large-scale and high-efficiency, higher requirements are put forward for blade materials. Traditional glass fiber composite materials gradually show bottlenecks in meeting the lightweight, high strength, and anti-fatigue performance of longer blades. Therefore, carbon fiber reinforced composite materials emerge as the times require. Due to their higher specific strength and specific modulus compared to glass fibers, the blades are lighter and thinner, which strongly promotes the development of large wind turbines.

[0003] As a large number of wind turbine blades enter the end-of-life period, the scrapped wind turbine blades are usually cut into smaller volumes by a crushing method and combined with other processes to realize the waste recycling of the scrapped wind turbine blades. However, the carbon fiber composite wind turbine blades have high hardness and strength, which cause great wear to the equipment. For a crusher with an integrated shear disc design, although the crushing ability is improved by setting multiple shear discs on the drive shaft, when a single shear disc is worn, it is difficult to replace it separately due to the integrated design, resulting in inconvenient maintenance and high costs. Summary of the Invention

[0004] In view of the above-mentioned drawbacks of the prior art, the present invention provides a recycling device for carbon fiber composite materials of wind turbine blades, which can effectively solve the problem in the prior art that for a crusher with an integrated shear disc design, although the crushing ability is improved by setting multiple shear discs on the drive shaft, when a single shear disc is worn, it is difficult to replace it separately due to the integrated design, resulting in inconvenient maintenance and high costs.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: The present invention provides a recycling device for carbon fiber composite materials of wind turbine blades, comprising: A bracket; A supporting platform, which is fixedly connected to the bracket by bolts and nuts, and an execution group for realizing the preliminary crushing of the wind turbine blade is arranged on the supporting platform; A crushing member, which is arranged inside the bracket and directly below the execution member; Wherein, the execution group includes a crushing box arranged on the support platform in a loop shape through fasteners, and two drive shafts are rotatably arranged inside the crushing box and distributed in the left-right direction and connected to an external drive unit; Wherein, a plurality of shear discs are respectively fixedly arranged on the circumferential outer walls of the two drive shafts.

[0006] Furthermore, a number of bosses are fixedly arranged on the left and right inner side walls of the crushing box in a staggered manner. Through the arrangement of the bosses, the situation that the wind power blade is stuck between two adjacent shearing discs and cannot fall during the shearing of the wind power blade by the shearing discs is avoided.

[0007] Furthermore, a number of shearing blades for realizing the crushing of the wind power blade are arranged on the circumferential outer wall of the shearing disc through fasteners, and the two groups of shearing discs on both sides are arranged between two adjacent bosses at corresponding positions.

[0008] Furthermore, the execution group further includes a feed hopper fixedly arranged directly above the crushing box. A feed chute is formed in any one side wall of the feed hopper, and a blanking member is arranged inside the feed hopper.

[0009] Furthermore, the blanking member includes a shaft rod arranged inside the feed hopper, one end of which rotatably penetrates through the feed hopper and is connected to an external drive unit. A number of sliding grooves are formed in the circumferential outer wall of the shaft rod, and a bearing plate is slidably arranged in each of the number of sliding grooves through an elastic member.

[0010] Furthermore, the crushing member includes a hammering box fixedly arranged inside the support and connected to the crushing box through a funnel. A transmission shaft is rotatably arranged inside the hammering box, one end of which is connected to an external drive unit. A number of pendulums for further hammering the sheared wind power blade are arranged on the circumferential outer wall of the transmission shaft.

[0011] Furthermore, cams are fixedly arranged on the circumferential outer walls of the two opposite ends of the transmission shaft. A matching member that is always in contact with the outer wall of the cam is arranged below the two cams inside the hammering box through a sliding member.

[0012] Furthermore, the matching member includes a sieve plate slidably arranged inside the hammering box. A number of blanking holes for facilitating the falling of the crushed wind power blade are formed in the outer wall of the sieve plate.

[0013] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: The present invention is provided with an execution group, and the cutting disc and the cutting blade are detachably arranged. The purpose is that when a single cutting blade is worn, the maintenance time can be reduced by replacing parts, avoiding the problem of difficult separate replacement due to the integrated design of the cutting disc and the cutting blade, resulting in inconvenient maintenance and high costs. During the rotation of the material supporting plate along with the shaft rod, the continuous feeding work of the wind turbine blade can be realized. Specifically, the feeding port is arranged on the side wall of the feeding hopper, and a plurality of material supporting plates are arranged along the circumferential direction. When one of the material supporting plates completes the material receiving work and rotates along with the shaft rod, when the unfilled material supporting plate rotates to the position of the material receiving groove, the feeding work of the next batch of wind turbine blades can be realized. By arranging a plurality of material supporting plates, the blank period existing in the feeding work of the wind turbine blades is reduced, thereby improving the overall crushing work efficiency of the wind turbine blades. Due to the blocking of the shaft rod and a plurality of material supporting plates, the sharp fragments are prevented from being thrown out during the crushing of the wind turbine blades, thereby improving the safety of the wind turbine blades during the crushing process.

[0018] The present invention will be further described below with reference to the embodiments. Embodiment

[0019] Please refer to Figure 1 - Figure 7 , the present invention provides a technical solution: a recycling device for carbon fiber composite materials of wind turbine blades, including: Support 1; Supporting platform 2, the supporting platform 2 is fixedly connected to the support 1 through bolts and nuts, and an execution group 21 for realizing the preliminary crushing of wind turbine blades is arranged on the supporting platform 2; Crushing part 3, the crushing part 3 is arranged inside the support 1 and directly below the executing part; Among them, the execution group 21 includes a crushing box 211 arranged on the supporting platform in a loop shape through fasteners, and two drive shafts 212 distributed in the left-right direction and connected to an external drive unit are rotatably arranged inside the crushing box 211; Among them, a plurality of shear discs 213 are fixedly arranged on the circumferential outer walls of the two drive shafts 212 respectively.

[0020] A plurality of convex platforms 214 are fixedly arranged on the left and right inner side walls of the crushing box 211 in a staggered manner. Through the arrangement of the convex platforms 214, the situation that the wind turbine blade is stuck between two adjacent shear discs 213 and cannot fall during the shearing of the wind turbine blade by the shear discs 213 is avoided.

[0021] A plurality of shear blades 215 for realizing the crushing of wind turbine blades are arranged on the circumferential outer walls of the shear discs 213 through fasteners, and the plurality of shear discs 213 on both sides are arranged between two adjacent convex platforms 214 at corresponding positions.

[0022] The execution group 21 further includes a feed hopper 22 fixedly arranged directly above the crushing box 211. A feed chute 221 is formed on any side wall of the feed hopper 22, and a blanking member 23 is arranged inside the feed hopper 22.

[0023] The blanking member 23 includes a shaft rod 231 arranged inside the feed hopper 22, with one end rotatably penetrating through the feed hopper 22 and connected to an external drive unit. A plurality of sliding grooves are formed on the circumferential outer wall of the shaft rod 231, and a bearing plate 232 is slidably arranged in each of the plurality of sliding grooves through an elastic member.

[0024] The crushing member 3 includes a hammering box 31 fixedly arranged inside the bracket 1 and connected to the crushing box 211 through a funnel. A transmission shaft 32 is rotatably arranged inside the hammering box 31, with one end connected to an external drive unit. A plurality of pendulums 33 for further hammering the wind turbine blade after shearing are arranged on the circumferential outer wall of the transmission shaft 32.

[0025] Circumferential outer walls of two opposite ends of the transmission shaft 32 are both fixedly provided with cams 34. Inside the hammering box 31 and below the two cams 34, a cooperating member that always fits against the outer wall of the cam 34 is arranged through a sliding member.

[0026] The cooperating member includes a sieve plate 35 slidably arranged inside the hammering box 31. A plurality of blanking holes 351 facilitating the falling of the crushed wind turbine blade are formed on the outer wall of the sieve plate 35.

[0027] During specific operation, the feeding and preliminary crushing of the wind turbine blade: As a large number of wind turbine blades enter the end - of - life period, the scrapped wind turbine blades are usually cut into smaller volumes by crushing and combined with other processes to achieve waste recycling of the scrapped wind turbine blades. However, the wind turbine blades made of carbon fiber composite materials have high hardness and strength, which cause great wear to the equipment. For the crusher with the integrated shear disc 213 design, although the crushing ability is improved by arranging multiple shear discs 213 on the drive shaft 212, when a single shear disc 213 is worn, it is difficult to replace it individually due to the integrated design, resulting in problems of inconvenient maintenance and high cost. At the same time, when carbon fiber undergoes brittle fracture, sharp fragments will be generated, and these fragments are thrown out under the high - speed rotation of the shear disc 213, thus causing potential safety hazards. Based on this, the recycling equipment for the carbon fiber composite material of the wind turbine blade is provided with an execution group 21, which can improve the efficiency of maintaining and replacing a single shear disc 213, and at the same time, block the flying fragments during the shearing process of the wind turbine blade, thereby improving the safety of the overall shearing work.

[0028] Specifically, a feed hopper 22 is provided above the crushing box 211. A feed groove 221 is formed in one side wall of the feed hopper 22. (By arranging the feed groove 221 on the side wall of the feed hopper 22, the efficiency and safety of the feeding operation of the wind turbine blade are improved by means of lateral feeding. Specifically, the traditional wind turbine blade usually adopts the method of directly feeding from above. In order to prevent sharp fragments from being thrown out during the shearing of the wind turbine blade, a baffle plate will be set in the feeding area. However, during the feeding process of the wind turbine blade, the equipment is always in working state. After the baffle plate is opened, the wind turbine blade that has not been completely sheared will still fly outwards, thus causing potential safety hazards. Moreover, during the batch feeding process of the wind turbine blade, the baffle plate needs to be frequently opened and closed, which is time-consuming and laborious and cannot ensure the continuity of the feeding operation of the wind turbine blade, thereby affecting the feeding efficiency).

[0029] The pre-treated wind turbine blade is pushed into the interior of the feed hopper 22 along the feed groove 221. Since a shaft rod 231 is rotatably arranged inside the feed hopper 22 and a number of bearing plates 232 are arranged on the outer wall of the shaft rod 231 in the circumferential direction, the wind turbine blade pushed into the interior of the feed hopper 22 will preferentially fall on the bearing plates 232. (The bearing plates 232 are arranged in a wedge shape, that is, the height of the bearing plates 232 gradually decreases from the side close to the shaft rod 231 to the side away from the shaft rod 231. The purpose of setting the bearing plates 232 in a wedge shape is to make the wind turbine blade located on the bearing plates 232 in an inclined manner to prevent the wind turbine blade from staying on the bearing plates 232. Moreover, a number of waist-shaped grooves are formed in the bearing plates 232 in the front-back direction. The purpose is to give a smaller space for the smaller wind turbine blade to fall, so that the smaller wind turbine blade directly drops to the lower crushing area). Subsequently, the external drive unit drives the shaft rod 231 and the bearing plates 232 arranged thereon to rotate synchronously. During the rotation of the bearing plates 232, the wind turbine blade located thereon will be driven to move. And during the movement, the vibration of the wind turbine blade is realized through the cooperation between the bearing plate and the inner wall of the feed hopper 22. (Specifically, a number of semi-circular protrusions are fixedly arranged on the left and right inner side walls of the feed hopper 22 along its direction. When the bearing plate 232 rotates to the position of the protrusion following the shaft rod 231, through the cooperation between its outer wall and a number of protrusions, the reciprocating telescopic operation is realized, and finally the vibration effect of the wind turbine blade on the bearing plate 232 is completed. Through this vibration setting and the cooperation with a number of waist-shaped grooves formed in the bearing plate 232, the falling work of the smaller wind turbine blade is further improved). When the bearing plate 232 supporting the wind turbine blade moves to a position perpendicular to the ground, the wind turbine blade placed thereon falls into the interior of the crushing box 211 by gravity.

[0030] It should be noted that during the rotation of the material receiving plate 232 following the shaft rod 231, continuous feeding of the wind power blade can be achieved. Specifically, the feeding port is arranged on the side wall of the feeding hopper 22, and a number of material receiving plates 232 are arranged along the circumferential direction. When one of the material receiving plates 232 finishes the material receiving work and rotates following the shaft rod 231, when the supporting plate that has not completed the material receiving rotates to the position of the material receiving groove, the feeding work of the next batch of wind power blades can be realized. By setting a number of material receiving plates 232, the blank period existing in the feeding work of the wind power blades is reduced, thereby improving the overall crushing efficiency of the wind power blades. Due to the blocking of the shaft rod 231 and a number of supporting plates, sharp fragments are prevented from being thrown out during the crushing of the wind power blades, thereby improving the safety of the wind power blades during the crushing process.

[0031] Meanwhile, after the wind power blade on the material receiving plate 232 falls into the interior of the lower crushing box 211 due to gravity, the supporting plate will still come into contact with the protrusion and vibrate during the rotation. The purpose is to shake off the wind power blades with smaller volume located inside the waist-shaped groove through this vibration, avoiding blockage of the waist-shaped groove.

[0032] The shear disc 213 and the shear blade 215 are detachably arranged. The purpose is that when a single shear blade 215 wears out, the maintenance time can be reduced by replacing parts, avoiding the problems of inconvenient maintenance and high cost caused by the integrated design of the shear disc 213 and the shear blade 215, which makes it difficult to replace them separately.

[0033] Secondary crushing work of the wind power blade: While the wind power blade is being crushed by the shear blade 215, the transmission shaft 32 is controlled to work through external drive, and a number of pendulums 33 arranged thereon are synchronously driven by the transmission shaft 32 to rotate. After the wind power blade completes the primary crushing work, it falls into the interior of the lower pendulum 33 box due to gravity through the funnel and comes into contact with the pendulum 33 to achieve further crushing work (the pendulums 33 are arranged on the outer wall of the transmission shaft 32, and the working area of the pendulums 33 is arranged in a serrated shape. When the wind power blade is hammered by the pendulums 33, the serrated working area can concentrate the impact force on a smaller contact area, generating a higher local pressure, which helps to further crush the wind power blade and improve the crushing efficiency, and finally obtain finer particles). The wind power blade that has completed the secondary crushing will freely fall downward due to gravity to the lower sieve plate 35 (the sieve plate 35 is arranged in a semi-circular shape, and a material dropping hole 351 is provided on its arc-shaped outer wall. Through the setting of the material dropping hole 351, the wind power blade fragments with larger and smaller volumes can be distinguished. The fragments of the wind power blades with smaller volume will pass through the material dropping hole 351 and directly fall into the externally arranged material receiving box below).

[0034] It should be noted that cam 34 is fixedly arranged on the circumferential outer wall at both ends of the transmission shaft 32 away from each other, and the inside of the hammering box 31 is connected to the sieve plate 35 through a sliding member. When the transmission shaft 32 drives the pendulum hammer 33 to rotate, the cam 34 also rotates following the transmission shaft 32. During the rotation, the sieve plate 35 realizes reciprocating sliding up and down through the cooperation of the cam 34 and the sliding member. Through this reciprocating vibration, it is avoided that the fragments of the larger wind turbine blades block the blanking hole 351, resulting in the problem that it is difficult for the fragments of the smaller wind turbine blades to fall. And through the interception of the sieve plate 35, the fragments of the larger wind turbine blades cannot fall, avoiding the mixing of the fragments of the larger and smaller wind turbine blades and the problem of difficult distinction.

[0035] It is worth emphasizing that the recycling equipment for the carbon fiber composite material of the wind turbine blade mainly has the following advantages: Advantage 1: The shear disc 213 and the shear blade 215 are detachably arranged. The purpose is that when a single shear blade 215 is worn, the maintenance time can be reduced by replacing the parts, avoiding the problems of inconvenient maintenance and high cost caused by the integral design of the shear disc 213 and the shear blade 215, which makes it difficult to replace them separately. During the rotation of the material receiving plate 232 following the shaft rod 231, the uninterrupted feeding work of the wind turbine blade can be realized. Specifically, the feeding port is arranged on the side wall of the feeding hopper 22, and a plurality of material receiving plates 232 are arranged along the circumferential direction. When one of the material receiving plates 232 finishes the material receiving work and rotates following the shaft rod 231, when the non-completed material receiving support plate rotates to the position of the material receiving groove, the feeding work of the next batch of wind turbine blades can be realized. By arranging a plurality of material receiving plates 232, the blanking period existing in the feeding work of the wind turbine blade is reduced, thereby improving the overall crushing efficiency of the wind turbine blade. Due to the blocking of the shaft rod 231 and a plurality of support plates, it is avoided that the sharp fragments are thrown out during the crushing of the wind turbine blade, thereby improving the safety of the wind turbine blade during the crushing process.

[0036] Advantage 2: The material receiving plate 232 is arranged in a wedge shape, that is, the height of the material receiving plate 232 gradually decreases from the side close to the shaft rod 231 to the side away from the shaft rod 231. The purpose of arranging the material receiving plate 232 in a wedge shape is to make the wind turbine blade located on the material receiving plate 232 in an inclined manner, avoiding the retention of the wind turbine blade on the material receiving plate 232. And a plurality of waist-shaped grooves are arranged on the material receiving plate 232 in the front-back direction. The purpose is to give the smaller wind turbine blade a space to fall, so that the smaller wind turbine blade directly falls into the lower crushing area.

[0037] Advantage three: A number of semi-circular protrusions are fixedly arranged on the left and right inner walls of the feeding hopper 22 along its direction. When the material receiving plate 232 rotates to the position of the protrusions following the shaft rod 231, through the cooperation between its outer wall and the number of protrusions, reciprocating telescopic work is realized, and finally the vibration effect of the wind power blade on the material receiving plate 232 is completed. Through the cooperation of this vibration setting and a number of waist-shaped slots opened on the material receiving plate 232, the falling work of the relatively small wind power blade is further improved. After the wind power blade on the material receiving plate 232 falls into the internal part of the crushing box 211 below by gravity, the supporting plate will still come into contact with the protrusions during the rotation process and realize vibration. The purpose is to vibrate and shake off the relatively small wind power blade that falls into the waist-shaped slot to avoid blockage of the waist-shaped slot.

[0038] Advantage four: Cam 34 is fixedly arranged on the circumferential outer wall at both ends of the transmission shaft 32 away from each other, and the sieve plate 35 is connected to the inside of the hammering box 31 through a sliding member. When the transmission shaft 32 drives the pendulum hammer 33 to rotate, the cam 34 also rotates following the transmission shaft 32. And during the rotation process, through the cooperation between the cam 34 and the sliding member, the sieve plate 35 realizes up and down reciprocating sliding. Through this reciprocating vibration, it is avoided that the fragments of the relatively large wind power blade block the material falling hole 351, resulting in the problem that the fragments of the relatively small wind power blade are difficult to fall. And through the interception of the sieve plate 35, the fragments of the relatively large wind power blade cannot fall, avoiding the problem that the fragments of the relatively large and relatively small wind power blades are mixed, resulting in difficult differentiation.
