[0008] Preferably, the top of the discharge box has a feed inlet, and the crushing and feeding assembly includes a mounting plate, a bottom support plate, a push plate, and a control cylinder. The mounting plate is fixedly installed on the top of the inner wall of the discharge box. The two ends of the bottom support plate are fixedly installed on the bottom of the mounting plate by connecting blocks and are located below the feed inlet. The control cylinder is fixedly installed on the inner wall of the discharge box. The push plate is located above the bottom support plate and installed at the output end of the control cylinder. A discharge port is provided between the mounting plate and the bottom support plate.

[0009] Preferably, a plurality of dividing blades are sequentially installed inside the discharge port, and a plurality of push blocks are sequentially installed on one side of the push plate, with the gaps between the push blocks and the dividing blades corresponding to each other.

A discharge groove is formed between the upper horizontal outer surface of the limiting baffle and the outer wall of the feeding hopper.

[0012] Preferably, a buffer assembly is provided at the bottom of the feed hopper. The bottom of the feed hopper is in the shape of an inverted frustum. The buffer assembly includes a housing and an air pump. The housing is installed on the outside of the bottom of the feed hopper. The air pump is installed on the outside of the housing and its output end is located inside the housing. An exhaust port is provided between the housing and the inner wall of the feed hopper.

[0013] Preferably, the ammunition filling box has an installation port on its top, and an adding hopper that communicates with the ammunition filling slot is installed in the installation port.

[0014] Preferably, the bottom of the ammunition filling box has a heating chamber, and a heating element is fixedly installed inside the heating chamber.

[0015] Preferably, a limiting plate is fixedly installed on one side of the inner wall of the limiting frame, and a plurality of limiting top blocks are fixedly installed on the other side of the inner wall of the limiting frame, with a guiding inclined surface provided on the top of the limiting top blocks.

[0016] A method for recycling and processing waste wind turbine blades includes the following steps:

[0017] S1. Pre-treatment: The waste wind turbine blades are initially cut into 5-8m segments and fed through a material conveying structure;

[0018] S2. Preliminary crushing operation: Steel balls are used as crushing tools. The steel balls are launched by a pneumatic pressurizer to initially crush the fan blades. The size of the initially crushed particles is similar to the volume of the steel balls.

[0019] S3, Secondary crushing operation: The crushing and feeding components in the discharge box can crush the fan blades after the initial crushing operation. At the same time, after secondary crushing, the waste fan blades on the local horizontal surface are completely crushed, and the waste fan blades above can automatically move downward, thus achieving the effect of automatic feeding.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention recycles wind turbine blades through impact, resulting in more stable crushing and easier control of the resulting particulate material.

[0022] 2. The present invention can further crush the wind turbine blade frame through the crushing and feeding component, thereby ensuring thorough crushing and controllable shape, making it more convenient for subsequent use.

[0023] 3. The present invention enables convenient recycling of crushing tools through the recycling component, thus saving manpower and facilitating continuous operation of the processing device.

[0024] 4. The present invention can blow outside air into the feed hopper through the exhaust port by means of the buffer component, thus forming an air wall between the fan blades and the electromagnetic plate. When the steel ball passes through the air wall, the impact force can be further reduced, and the air direction is upward, which can also prevent the steel ball from falling directly downward, making it easier to recover the steel ball.

[0037] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] This embodiment provides a technical solution: a waste wind turbine blade recycling and processing device, such as... Figures 1-9 As shown, the device includes a conveying structure 1, a manual platform 2, and a crushing device 3. The manual platform 2 is located behind the crushing device 3, and a transfer plate 4 is fixedly installed on the front side of the manual platform 2. The transfer plate 4 is located between one end of the conveying structure 1 and the top of the crushing device 3. The conveying structure 1 includes a horizontal conveying platform 101 and a lifting conveying platform 102. The lifting conveying platform 102 is located between the horizontal conveying platform 101 and the transfer plate 4. The waste fan blades are initially cut into segments of 5-8m and fed through the conveying structure 1. The operator uses a hoisting device to place the waste fan blades into the crushing device 3 on the manual platform 2 for crushing.

[0040] In specific implementations, such as Figures 2-4As shown, the crushing device 3 includes a feed hopper 301, a limiting frame 302, a discharge box 303, and a pneumatic pressurizer 304. The feed hopper 301, the limiting frame 302, and the discharge box 303 are fixedly installed sequentially from top to bottom. A filling box 5 is fixedly installed on one side of the feed hopper 301. A row of filling slots 6 are opened between the filling box 5 and the inner wall of the feed hopper 301. The pneumatic pressurizer 304 is installed on one side of the filling box 5. Steel balls are used as the crushing tool to crush the steel balls into powder. The steel balls are placed in the filling slot 6 and propelled out by the pneumatic pressurizer 304. The pneumatic pressurizer 304 includes an air compressor, an air storage container, and a pipeline for controlling the discharge of high-pressure gas. The air compressor compresses air into the air storage container. When the steel balls are launched, the exhaust pipeline is opened, and the high-pressure gas can eject the steel balls. Therefore, the steel balls can impact the waste fan blades. Under sufficient pressure, the steel balls can penetrate the fan blades, thereby breaking them into small particles at the bullet hole.

[0041] In specific implementations, such as Figures 4-6 As shown, a crushing and feeding assembly 7 for crushing the bottom of blades is provided inside the discharge box 303. The top of the discharge box 303 has a feed inlet 8. The crushing and feeding assembly 7 includes a mounting plate 701, a bottom support plate 702, a pusher plate 703, and a control cylinder 704. The mounting plate 701 is fixedly installed on the top of the inner wall of the discharge box 303. The bottom support plate 702 is fixedly installed at both ends on the bottom of the mounting plate 701 via connecting blocks and is located below the feed inlet 8. The control cylinder 704 is fixedly installed on the inner wall of the discharge box 303. The pusher plate 703 is located on the bottom support plate. Above the plate 702 and installed at the output end of the control cylinder 704, a discharge port 9 is provided between the mounting plate 701 and the base plate 702. Multiple dividing blades 10 are installed in sequence in the discharge port 9. Multiple push blocks 11 are installed in sequence on one side of the push plate 703. The gaps between the push blocks 11 and the dividing blades 10 correspond to each other. The distance between the dividing blades 10 is greater than the diameter of the filling groove 6. The push plate 703 can be pushed by the control cylinder 704, and then the push blocks 11 can impact the bottom of the waste fan blades and the same part as the discharge port 9 into fragments.

[0042] Furthermore, a discharge port 12 is provided on one side of the discharge box 303, and a guide plate 13 is installed inside the discharge port 12. The small granular materials generated can be easily discharged from the discharge port 12 through the guide plate 13.

[0043] Furthermore, an installation port is provided on the top of the ammunition box 5, and an adding hopper 18 connected to the ammunition filling slot 6 is installed in the installation port, through which steel balls can be easily added into the ammunition box 5.

[0044] Furthermore, a heating chamber is provided at the bottom of the ammunition box 5, and a heating element 19 is fixedly installed inside the heating chamber. During the steel ball preparation stage, the heating element 19 can heat the steel ball, thereby softening it when it comes into contact with the fan blades, thus greatly improving the penetration probability.

[0045] Furthermore, a limiting plate 20 is fixedly installed on one side of the inner wall of the limiting frame 302, and multiple limiting top blocks 21 are fixedly installed on the other side of the inner wall of the limiting frame 302. The top of the limiting top block 21 is provided with a guiding slope 22. The limiting plate 20 and the limiting top block 21 can conveniently limit a single fan blade to ensure good stability during the crushing operation. The limiting frame 302 and the discharge box 303 can conveniently discharge the small particles of material that have been initially crushed. Since the volume of the fan blade after pre-processing and cutting is also relatively large, in this embodiment, the processing device preferably crushes one fan blade block at a time.

[0046] The steel balls have the same diameter as the filling groove 6, the height of the discharge port 9 is slightly larger than the diameter of the filling groove 6, and the spacing between adjacent dividing blades 10 is the same as the spacing between adjacent filling grooves 6. The steel balls are placed in rows within the filling groove 6, and the pneumatic pressurizer 304 ejects them. This allows the steel balls to impact the discarded fan blades. Under sufficient pressure, the steel balls can penetrate the fan blades, breaking them into small particles at the bullet holes. The remaining fan blade frame, after being pierced, can move into the discharge box 303 and contact the bottom support plate 702. The control cylinder 704 pushes the push plate 703, which, along with the push block 11 on one side, pushes the bottom fan blade frame through the discharge port 9, crushing it into strips. These strips are then further pulverized into smaller pieces by the dividing blades 10. The pulverized pieces are shaped as follows: Figure 9 As shown, in this state, the crushing and cutting position is at the connection point of the outermost edge of each bullet hole, and the crushing and shaping is stable and less difficult.

[0047] Example 2

[0048] This embodiment provides a technical solution: a waste wind turbine blade recycling and processing device, such as... Figures 1-9 As shown, the device includes a conveying structure 1, a manual platform 2, and a crushing device 3. The manual platform 2 is located behind the crushing device 3, and a transfer plate 4 is fixedly installed on the front side of the manual platform 2. The transfer plate 4 is located between one end of the conveying structure 1 and the top of the crushing device 3. The conveying structure 1 includes a horizontal conveying platform 101 and a lifting conveying platform 102. The lifting conveying platform 102 is located between the horizontal conveying platform 101 and the transfer plate 4. The waste fan blades are initially cut into segments of 5-8m and fed through the conveying structure 1. The operator uses a hoisting device to place the waste fan blades into the crushing device 3 on the manual platform 2 for crushing.

[0049] In specific implementations, such as Figures 2-4 As shown, the crushing device 3 includes a feed hopper 301, a limiting frame 302, a discharge box 303, and a pneumatic pressurizer 304. The feed hopper 301, the limiting frame 302, and the discharge box 303 are fixedly installed from top to bottom. A filling box 5 is fixedly installed on one side of the feed hopper 301. A row of filling slots 6 are opened between the filling box 5 and the inner wall of the feed hopper 301. The pneumatic pressurizer 304 is installed on one side of the filling box 5. Steel balls are used as crushing tools. The steel balls are placed in rows in the filling slots 6. The pneumatic pressurizer 304 is used to push the steel balls out. Therefore, the steel balls can impact the waste fan blades. Under sufficient pressure, the steel balls can penetrate the fan blades and break them into small particles.

[0050] In specific implementations, such as Figures 4-6 As shown, a crushing and feeding assembly 7 for crushing the bottom of blades is provided inside the discharge box 303. The top of the discharge box 303 has a feed inlet 8. The crushing and feeding assembly 7 includes a mounting plate 701, a bottom support plate 702, a pusher plate 703, and a control cylinder 704. The mounting plate 701 is fixedly installed on the top of the inner wall of the discharge box 303. The bottom support plate 702 is fixedly installed at both ends on the bottom of the mounting plate 701 via connecting blocks and is located below the feed inlet 8. The control cylinder 704 is fixedly installed on the inner wall of the discharge box 303. The pusher plate 703 is located on the bottom support plate. Above the plate 702 and installed at the output end of the control cylinder 704, a discharge port 9 is provided between the mounting plate 701 and the base plate 702. Multiple dividing blades 10 are installed in sequence in the discharge port 9. Multiple push blocks 11 are installed in sequence on one side of the push plate 703. The gaps between the push blocks 11 and the dividing blades 10 correspond to each other. The distance between the dividing blades 10 is greater than the diameter of the filling groove 6. The push plate 703 can be pushed by the control cylinder 704, and then the push blocks 11 can impact the bottom of the waste fan blades and the same part as the discharge port 9 into fragments.

[0051] Furthermore, a discharge port 12 is provided on one side of the discharge box 303, and a guide plate 13 is installed inside the discharge port 12. The small granular materials generated can be easily discharged from the discharge port 12 through the guide plate 13.

[0052] Furthermore, an installation port is provided on the top of the ammunition box 5, and an adding hopper 18 connected to the ammunition filling slot 6 is installed in the installation port, through which steel balls can be easily added into the ammunition box 5.

[0053] Furthermore, a heating chamber is provided at the bottom of the ammunition box 5, and a heating element 19 is fixedly installed inside the heating chamber. During the steel ball preparation stage, the heating element 19 can heat the steel ball, thereby softening it when it comes into contact with the fan blades, thus greatly improving the penetration probability.

[0054] Furthermore, a limiting plate 20 is fixedly installed on one side of the inner wall of the limiting frame 302, and multiple limiting top blocks 21 are fixedly installed on the other side of the inner wall of the limiting frame 302. The top of the limiting top block 21 is provided with a guiding slope 22. The limiting plate 20 and the limiting top block 21 can conveniently limit the fan blades to ensure good stability during the crushing operation. The limiting frame 302 and the discharge box 303 can conveniently discharge the small particles of material that have been initially crushed.

[0055] In this embodiment, the steel balls have the same diameter as the filling groove 6, the height of the discharge port 9 is half the height of the discharge port 9 in Example 1, and the spacing between adjacent dividing blades 10 is the same as the spacing between adjacent filling grooves 6. The steel balls are placed in rows in the filling groove 6, and the steel balls are ejected by the pneumatic pressurizer 304. Therefore, the steel balls can impact the waste fan blades. Under sufficient pressure, the steel balls can penetrate the fan blades, thereby crushing them into small particles at the bullet holes. After being penetrated, the remaining fan blade frame can move into the discharge box 303 and contact the bottom support plate 702. The control cylinder 704 can push the push plate 703 to move. The push plate 703 and the push block 11 on one side can push the bottom fan blade frame through the discharge port 9 and crush it into strips. Under the cutting of the dividing blades 10, it continues to be crushed into small pieces. The crushed shape is as follows: Figure 10 As shown, the blocks obtained by crushing in this state are smaller in volume, but the cutting position requires cutting the entire intact segment, so the cutting is more difficult.

[0056] Example 3

[0057] This embodiment is a further optimization based on the above embodiments. The parts that are the same as those in the foregoing technical solutions will not be repeated here. Figures 2-4 As shown, in order to better realize the present invention, the following configuration is adopted: In this embodiment, in order to reduce the wear and tear of steel balls on the inside of the feed hopper 301 and facilitate the recovery of steel balls, a corresponding structure is added inside the feed hopper 301.

[0058] In specific implementations, such as Figure 2 and Figure 3As shown, a recycling component 14 is provided inside the feeding hopper 301. The recycling component 14 includes an electromagnetic plate 1401 and a limiting baffle 1402. The electromagnetic plate 1401 is installed on the other side of the inner wall of the feeding hopper 301 and corresponds to the filling groove 6. The limiting baffle 1402 is fixedly installed on the other side of the inner wall of the feeding hopper 301 and is located at the bottom of the electromagnetic plate 1401. A discharge groove 15 is opened between the upper horizontal outer surface of the limiting baffle 1402 and the outer wall of the feeding hopper 301, through which steel balls penetrate the fan blades. The impact force is severely lost after the impact, so it can move in an arc-shaped downward trajectory. When the electromagnetic plate 1401 is connected to an external power source, it can generate magnetism, so the electromagnetic plate 1401 can attract the falling steel ball. After one impact, the electromagnetic plate 1401 is turned off, and the steel ball can fall downward onto the limiting baffle plate 1402. The steel ball can be discharged from the feed hopper 301 through the ejection groove 15 on the limiting baffle plate 1402, so the steel ball can be easily recovered from the outside.

[0059] In specific implementations, such as Figure 2 and Figure 3 As shown, a buffer assembly 16 is provided at the bottom of the feed hopper 301. The bottom of the feed hopper 301 is in the shape of an inverted frustum. The buffer assembly 16 includes a housing 1601 and an air pump 1602. The housing 1601 is installed on the outer side of the bottom of the feed hopper 301, and the air pump 1602 is installed on the outer side of the housing 1601 with its output end located inside the housing 1601. An exhaust port 17 is provided between the housing 1601 and the inner wall of the feed hopper 301. The buffer assembly 16 can further reduce the impact force of the steel ball. The air pump 1602 can blow outside air into the feed hopper 301 through the exhaust port 17. Therefore, an air wall can be formed between the fan blades and the electromagnetic plate 1401. When the steel ball passes through the air wall, the impact force can be further reduced. Moreover, the air direction is upward, which can also prevent the steel ball from falling directly downward, making it easier to recover the steel ball.

[0060] The above are merely preferred embodiments of the present invention and are illustrative in nature, not restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
