Technical Field

[0001] This utility model relates to the field of waste wind turbine blade technology, specifically to a waste wind turbine blade crushing and recycling auxiliary equipment. Background Technology

[0002] Waste wind turbine blades refer to the blades of wind turbine generator sets that have reached the end of their service life or have been scrapped due to damage. Wind turbine blades are generally made of materials such as glass fiber, carbon fiber and epoxy resin, and are manufactured through a heat curing process. They are characterized by light weight, high strength and strong wind resistance. When recycling waste wind turbine blades, they need to be crushed by a crushing device to improve the pyrolysis recovery efficiency.

[0003] Currently, auxiliary recycling equipment lacks a magnetic separation and screening mechanism. Conventional crushing equipment typically only pulverizes the blades into mixed fragments. If non-metallic fragments are mixed in, it will affect the purity of the pyrolysis process or reduce the quality of the product used as recycled filler. Therefore, an auxiliary recycling equipment for waste wind turbine blade crushing is proposed to add a magnetic separation and screening mechanism. By using drum magnetic separation and multi-stage screening, the quality of fragment recycling can be improved, the efficiency of subsequent pyrolysis can be improved, and the overall effect can be enhanced.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] To improve the quality of scrap recycling, enhance subsequent pyrolysis efficiency, and thus improve overall performance, such as... Figure 1-4 As shown, the waste wind turbine blade crushing and recycling equipment of this utility model includes a magnetic separator 1, a screening component 2 and a negative pressure component 4. The screening component 2 is provided at the bottom of the magnetic separator 1, a waste recycling component 3 is provided on one side of the screening component 2, a negative pressure component 4 is provided on one side of the waste recycling component 3, and a recycling component 5 is provided on the other side of the screening component 2. A rotating roller 101 is installed inside the magnetic separator 1 via a bearing. A permanent magnet 102 is fixedly sleeved around the rotating roller 101. A scraper 103 corresponding to the rotating roller 101 is bolted to one side of the magnetic separator 1. The screening assembly 2 includes a screening box 201, and the bottom of the magnetic separator 1 is connected to the screening box 201. A screen plate 202 is slidably connected inside the screening box 201.

[0018] In use, the waste wind turbine blade fragments that have been initially crushed are fed into the magnetic separator 1. The drive motor 6 is started, which drives the rotating roller 101 and the permanent magnet 102 on it to rotate slowly. Ferromagnetic metal impurities in the fragments are attracted by the permanent magnet 102 and rotate with it. When they reach the scraper 103, they are scraped off and fall into the first recycling box 301 through the discharge port 104, thus completing the separation of metal impurities.

[0019] The scraper blade 103 is made of polyurethane.

[0020] To improve dust removal efficiency, for example, such as Figure 1 , Figure 3As shown, the present invention also includes a dust storage tank 401, a vacuum pump 402 connected to one side of the dust storage tank 401 by bolts, and the air inlet of the vacuum pump 402 located inside the dust storage tank 401. A filter plate 403 is fixedly installed inside the dust storage tank 401 by a slot.

[0021] When in use, the vacuum pump 402 is started, and negative pressure is generated in the dust storage tank 401. Light dust generated during the recycling process is sucked into the dust storage tank 401 and collected by the filter plate 403. The purified air is discharged, thereby achieving the purpose of dust removal.

[0022] For example, such as Figure 2 As shown, this utility model also includes a discharge port 104 on one side of the magnetic separator 1 at the bottom of the scraper 103. On the other side of the magnetic separator 1, a driven roller 105 corresponding to the rotating roller 101 is installed by a bearing. A guide plate 106 is bolted to the top of the driven roller 105 on one side of the magnetic separator 1. A receiving groove 107 is bolted to one side of the magnetic separator 1, and the receiving groove 107 communicates with the magnetic separator 1. A guide plate 108 is bolted to the bottom of the discharge end of the receiving groove 107.

[0023] In use, the receiving trough 107 guides the crushed material evenly onto the rotating roller 101 via the guide plate 108 for magnetic separation. At the same time, the guide plate 106, the driven roller 105, and the rotating roller 101 work together to allow the magnetically separated material to come into contact with the rotating roller 101 again for secondary magnetic separation, ensuring the quality of magnetic separation.

[0024] For example, such as Figure 3 As shown, the present invention also includes the waste recycling component 3, which includes a first recycling box 301. The first recycling box 301 is connected to the screening box 201 by bolts, and the first recycling box 301 is connected to the discharge port 104. A filter screen 302 is provided inside the first recycling box 301.

[0025] During use, the metal impurities discharged from the magnetic separator 1 fall into the first recovery box 301. The filter screen 302 separates the recovered metal impurities from the dust and recovers them to ensure the purity of the recovered metal.

[0026] For example, such as Figure 4 As shown, the present invention also includes a vibration motor 203 bolted to the inner side of the screening box 201, and the output end of the vibration motor 203 is located at the bottom of the screen plate 202. A drawer 204 is slidably connected to the bottom of the screening box 201.

[0027] When in use, start the vibration motor 203 to drive the screen plate 202 to vibrate at high frequency. The crushed material falling into the screening box 201 is screened under the action of vibration: fine material with a particle size smaller than the mesh of the screen plate 202 passes through the screen holes and falls into the drawer 204 at the bottom; coarse material with a larger particle size moves along the inclined surface of the screen plate 202 and finally enters the recycling chamber 502 of the second recycling box 501.

[0028] For example, such as Figure 4 As shown, the present invention also includes the following: the recycling component 5 includes a second recycling box 501, the second recycling box 501 has a recycling cavity 502 corresponding to the sieve plate 202, the surface of the magnetic separator 1 is connected to a drive motor 6 by bolts, and the drive motor 6 is connected to a rotating roller 101 by a drive shaft.

[0029] During use, the screened material is discharged from the end of the screen plate 202 and directly enters the recovery chamber 502 of the second recovery box 501 to complete the collection of materials of different particle sizes. The magnetic separator 1 includes a controller, and the vibration motor 203, vacuum pump 402 and drive motor 6 are all electrically connected to the controller through wires.

[0030] In use, the waste wind turbine blade fragments, which have undergone preliminary crushing, are first fed into the equipment through the receiving trough 107. The guide plate 108 at the bottom of the receiving trough 107 guides the fragments smoothly into the magnetic separator 1. At this time, the drive motor 6 is started, and the drive motor 6 drives the rotating roller 101 to rotate through the drive shaft. The permanent magnet 102 around the rotating roller 101 generates a magnetic field. When the fragments pass through the area between the rotating roller 101 and the driven roller 105, the metal impurities mixed in the fragments are attracted to the surface of the rotating roller 101 by the permanent magnet 102. As the rotating roller 101 continues to rotate, the metal impurities attracted to its surface are carried to the scraper plate 103. The scraper plate 103 scrapes the metal impurities off the surface of the rotating roller 101. The scraped metal impurities enter the first recycling box 301 of the waste recycling component 3 through the discharge port 104 on the side of the magnetic separator 1 for recycling. After removing metallic impurities, the non-metallic scraps pass through the bottom of the magnetic separator 1 and enter the screening box 201 of the screening assembly 2 under the action of gravity. The vibration motor 203 inside the screening box 201 is activated, and the output end of the vibration motor 203 drives the screen plate 202 to vibrate. The vibration is used to achieve multi-stage screening of the non-metallic scraps. During the screening process, the smaller scraps fall through the screen holes of the screen plate 202 into the drawer 204 at the bottom of the screening box 201 for collection. The larger scraps that cannot pass through the screen plate 202 are pushed by the vibration of the inclined screen plate 202 into the recycling assembly 5 on the other side of the screening box 201, and finally fall into the recycling chamber 502 of the second recycling box 501. This achieves the classification and recycling of non-metallic scraps of different sizes, providing convenience for subsequent processing for different purposes. Throughout the operation of the equipment, the vacuum pump 402 of the negative pressure component 4 is activated simultaneously. The vacuum pump 402 evacuates air from the dust storage tank 401, creating a negative pressure environment inside the dust storage tank 401. Since the dust storage tank 401 is connected to the waste recycling component 3, screening component 2, and other areas by airflow, the dust generated during equipment operation will be drawn into the dust storage tank 401 under the action of negative pressure. When the dust-laden airflow passes through the filter plate 403 inside the dust storage tank 401, the filter plate 403 filters the dust and intercepts it inside the dust storage tank 401. The filtered clean air is then discharged outside the equipment through the vacuum pump 402. This effectively reduces the pollution of the working environment by dust during equipment operation, reduces the risk of dust being inhaled by operators, and prevents dust from adhering to the surface of internal parts of the equipment, affecting the operating accuracy of the equipment. This significantly improves the practicality and safety of the equipment.
