Technical Field

[0001] This application relates to the field of wind turbine blade recycling, and more specifically, to a wind turbine blade recycling and crushing device. Background Technology

[0002] In construction engineering, waste wind turbine blades can be used as filler in concrete structures. Specifically, the waste wind turbine blades are crushed and recycled. The existing crushing method involves feeding the waste wind turbine blades into a crusher for crushing. The crusher has two opposing crushing rollers at the top to crush the waste wind turbine blades. However, this crusher performs single-pass crushing, which results in poor crushing effect. Therefore, we propose a wind turbine blade recycling and crushing device. Utility Model Content

[0003] To overcome the shortcomings of existing methods, this application provides a wind turbine blade recycling and crushing device, which can solve the problem of poor crushing effect of the aforementioned crusher.

[0004] The technical solution adopted by the embodiments of this application to solve its technical problem is: a wind turbine blade recycling and crushing device, including a crushing box for crushing wind turbine blades, a first crushing mechanism and a second crushing mechanism are installed in the crushing box, an inclined discharge plate is installed at the bottom of the crushing box, the second crushing mechanism rotates through the discharge plate, and a driving mechanism is installed on the outer wall of the crushing box, the driving mechanism is connected to the first crushing mechanism and the second crushing mechanism.

[0005] In one specific implementation, the first crushing mechanism includes two first crushing rollers, both of which are rotatably mounted on the top of the crushing box, and each of the two first crushing rollers is equipped with a first flat gear at one end. The two first flat gears are meshed with each other, and the driving mechanism drives one of the first crushing rollers.

[0006] In one specific implementation, the second crushing mechanism includes a partition plate fixedly installed inside the crushing box. The bottom of the partition plate is connected to three crushing cylinders. Each of the three crushing cylinders is provided with a second crushing roller. The bottom of each of the three second crushing rollers is fixedly connected to a rotating shaft that rotates through the discharge plate.

[0007] In one specific implementation, the second crushing mechanism further includes a drive shaft that drives the drive mechanism, the drive shaft rotatably passing through the partition and the discharge plate, and the drive shaft drives the three rotating shafts.

[0008] In one specific implementation, a limiting ring is fixedly installed on the top of the partition, and a receiving plate is fixedly connected to the top of the limiting ring. One end of the receiving plate is fixedly connected to the inner wall of the crushing box.

[0009] In one specific implementation, two scraper plates are fixedly connected to the outer wall of the drive shaft. Both scraper plates are slidably disposed on the partition plate, and one end of each scraper plate is slidably in contact with the inner wall of the limiting ring.

[0010] In one specific implementation, crushing teeth are fixedly installed on the inner wall of the crushing cylinder, and the crushing teeth are staggered from the teeth on the outer wall of the second crushing roller.

[0011] In one specific implementation, the drive mechanism includes a motor, the drive shaft of which is connected to a connecting shaft, the connecting shaft driving one of the first crushing rollers and the transmission shaft.

[0012] The advantages of this embodiment are: by installing a first crushing mechanism in the crushing box, the first crushing mechanism initially crushes the waste fan blades, causing the blade fragments to fall downwards to the second crushing mechanism. The blade fragments then fall between the second crushing roller and the crushing cylinder. The drive mechanism drives the second crushing roller to rotate, so that the second crushing roller cooperates with the crushing cylinder to finely crush the blade fragments that have fallen between them, thereby improving the crushing effect. By installing a limiting ring on the top of the partition plate, and connecting the top of the limiting ring to a receiving plate, the initially crushed blade fragments fall into the limiting ring through the receiving plate. At the same time, the drive shaft drives the scraper to move, so that the blade fragments can fall into the crushing cylinder for crushing. Attached Figure Description

Detailed Implementation

[0020] The technical solution in this application embodiment is to solve the problem of poor crushing effect in the aforementioned crusher, and the overall approach is as follows:

[0021] Example:

[0022] Please see Figure 1-6 A wind turbine blade recycling and crushing device includes a crushing box 10 for crushing wind turbine blades. A first crushing mechanism 20 and a second crushing mechanism 30 are installed inside the crushing box 10. An inclined discharge plate 40 is installed at the bottom of the crushing box 10. The second crushing mechanism 30 rotates through the discharge plate 40. A drive mechanism 50 is installed on the outer wall of the crushing box 10. The drive mechanism 50 drives the first crushing mechanism 20 and the second crushing mechanism 30. Specifically, the top of the crushing box 10 is open, and an outlet is opened on the side wall of the crushing box 10. The outlet is located at the bottom. The discharge plate 40 is inclined so that the wind turbine blade fragments are discharged from the outlet of the crushing box 10 through the discharge plate 40. Waste wind turbine blades are fed into the first crushing mechanism 20 from the top of the crushing box 10. After being initially crushed by the first crushing mechanism 20, they are then finely crushed by the second crushing mechanism 30, thereby improving the crushing effect.

[0023] See Figure 1 and 3 The first crushing mechanism 20 includes two first crushing rollers 210, both of which are rotatably mounted on the top of the crushing box 10. Each of the two first crushing rollers 210 is equipped with a first spur gear 220 at one end. The two first spur gears 220 are meshed with each other. The drive mechanism 50 drives one of the first crushing rollers 210. When set up, the first crushing roller 210 is provided with an intermediate shaft. The two ends of the intermediate shaft rotatably pass through the two end side walls of the crushing box 10. The first spur gear 220 is mounted on the intermediate shaft. At the same time, the drive mechanism 50 drives the intermediate shaft so that the two first crushing rollers 210 move towards each other to crush the fan blades.

[0024] See Figure 3The second crushing mechanism 30 includes a partition plate 310 fixedly installed inside the crushing box 10. The bottom of the partition plate 310 is connected to three crushing cylinders 320. Each of the three crushing cylinders 320 is equipped with a second crushing roller 330. The bottom of each of the three second crushing rollers 330 is fixedly connected to a rotating shaft 340 that rotatably passes through the discharge plate 40. The second crushing mechanism 30 also includes a drive shaft 350 that drives the drive mechanism 50. The drive shaft 350 rotatably passes through the partition plate 310 and the discharge plate 40, and the drive shaft 350 is connected to the three… In the specific configuration of the drive shaft 340, a support plate is also fixedly installed on the inner wall of the crushing box 10. The bottom of the three crushing cylinders 320 is connected to the support plate, and the support plate supports the crushing cylinders 320. The drive shaft 350 rotates through the support plate. Furthermore, a second flat gear is fixedly sleeved on the bottom of the drive shaft 350, and a third flat gear is installed on the bottom of the three shafts 340. The three third flat gears mesh with the second flat gears to realize that the drive shaft 350 drives the three shafts 340 to rotate.

[0025] See Figure 3 A limiting ring 60 is fixedly installed on the top of the partition 310. A receiving plate 610 is fixedly connected to the top of the limiting ring 60. One end of the receiving plate 610 is fixedly connected to the inner wall of the crushing box 10. It should be noted that the receiving plate 610 is funnel-shaped and is used to receive the fan blades crushed by the first crushing mechanism 20, so that the fan blade fragments enter the limiting ring 60 through the receiving plate 610 and fall onto the partition 310.

[0026] See Figure 3 Two scraper plates 70 are fixedly connected to the outer wall of the drive shaft 350. Both scraper plates 70 are slidably disposed on the partition plate 310, and one end of each scraper plate 70 is slidably contacted with the inner wall of the limiting ring 60. Specifically, the drive shaft 350 drives the two scraper plates 70 to slide on the partition plate 310, thereby causing the fan blade fragments to fall into the crushing cylinder 320 and be finely crushed by the second crushing mechanism 30.

[0027] See Figure 6 Crushing teeth 80 are fixedly installed on the inner wall of the crushing cylinder 320. The crushing teeth 80 are offset from the teeth on the outer wall of the second crushing roller 330. When set, the second crushing roller 330 rotates inside the crushing cylinder 320, so that the second crushing roller 330 cooperates with the crushing teeth 80 to finely crush the fan blade fragments that fall into the crushing cylinder 320.

[0028] See Figure 4 and 5The drive mechanism 50 includes a motor 510, and the drive shaft of the motor 510 is connected to a connecting shaft 520. The connecting shaft 520 drives one of the first crushing rollers 210 and a transmission shaft 350. It should be noted that a first bevel gear is installed at the bottom of the transmission shaft 350, and a second bevel gear is installed at one end of the connecting shaft 520. The first bevel gear and the second bevel gear are meshed. At the same time, a first pulley is fixedly sleeved on the connecting shaft 520, and a second pulley is fixedly sleeved on the intermediate shaft of one of the first crushing rollers 210. The same transmission belt is wound on the first pulley and the second pulley to realize that the connecting shaft 520 drives the transmission shaft 350 and the first crushing roller 210 to rotate.

[0029] When this application is used:

[0030] The waste wind turbine blades are fed into the crushing box 10 by the equipment. At the same time, the motor 510 is started, which drives the connecting shaft 520 to rotate. The connecting shaft 520 drives one of the first crushing rollers 210 to rotate, and then the two first crushing rollers 210 rotate towards each other to initially crush the wind turbine blades. The crushed wind turbine blade fragments fall into the limiting ring 60 through the receiving plate 610. At the same time, the connecting shaft 520 drives the transmission shaft 350 to rotate, which drives the three rotating shafts 340 to rotate, thereby causing the three second crushing rollers 330 to rotate. Meanwhile, the transmission shaft 350 drives the scraper 70 to rotate on the partition plate 310, scraping the wind turbine blade fragments on the partition plate 310 into the crushing cylinder 320. Through the cooperation of the second crushing rollers 330 and the crushing teeth 80, the wind turbine blade fragments are finely crushed. Finally, the wind turbine blade fragments are discharged from the crushing cylinder 320 onto the discharge plate 40.

[0031] It should be noted that the specific model and specifications of motor 510 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0032] The power supply and principle of motor 510 are clear to those skilled in the art and will not be described in detail here.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
