Description

Technical Field

[0001] This invention relates to the field of wind turbine blade recycling technology, specifically to an integrated module recycling system for waste wind turbine blades. Background Technology

[0002] Wind turbine blades contain fiber reinforcement materials (such as glass fiber or carbon fiber), plastic polymers (polyester or epoxy resin), sandwich materials (PVC, PET, or balsa wood), polyurethane coatings, and fiberglass, among others. Some of these materials give wind turbine blades extremely high recycling value. Currently, the recycling of waste wind turbine blades often involves the coordinated use of various specialized equipment. Existing technologies require steps such as cutting, crushing, and screening. These steps necessitate transporting the waste wind turbine blades to the corresponding equipment for each recycling step. Currently, the equipment used for each step of waste wind turbine blade recycling is relatively dispersed. After each step, the generated materials need to be transferred to the equipment for the next step. This transportation process consumes significant manpower and resources, increasing the cost of waste wind turbine blade recycling and reducing its efficiency.

[0026] Specifically, the crushing device includes: a crushing pallet, a crusher, a conveyor belt, a fourth drive, and multiple crushing telescopic columns;

[0027] The pulverizer is mounted on the pulverizing tray and is used to pulverize the blade fragments into blade particles;

Detailed Implementation

[0045] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0046] Figure 1 This is a schematic diagram of an integrated module recycling system for waste wind turbine blades. Figure 2 This is a schematic diagram of the installation structure of the first and second slides in an integrated module recycling system for waste wind turbine blades. Figure 3 This is a schematic diagram of an integrated modular recycling system for waste wind turbine blades, excluding the installation of a cutting machine, crusher, and screening device. Figure 4 This is a schematic diagram of the cutting device in an integrated modular recycling system for waste wind turbine blades, as shown below. Figures 1-4 As shown, this invention provides an integrated module recycling system for waste wind turbine blades, the integrated module recycling system for waste wind turbine blades comprising:

[0047] Base 1 has a through groove;

[0048] The first slide 2 and the second slide 3 are both slidably disposed in the through groove. The first slide 2 and the second slide 3 can move horizontally toward each other or horizontally away from each other along the extension direction of the through groove.

[0049] The cutting device 4 is mounted on the first slide table 2 and can extend and retract vertically. The cutting device 4 is used to cut waste wind turbine blades into blade fragments.

[0050] The crushing device 5 is disposed on the base 1 and located above the cutting device 4. The crushing device 5 can extend and retract vertically. The crushing device 5 is used to crush the blade fragments into blade particles.

[0051] The screening device 6 is fixed on the second slide table 3 and is used to screen the blade particles formed after being crushed by the crushing device 5.

[0052] The integrated module recycling system for waste wind turbine blades provided by this invention has a through groove on the base 1, and the first slide 2 and the second slide 3 are both slidably disposed in the through groove, such as... Figure 1 and Figure 2 As shown, the upper surfaces of the first slide 2, the second slide 3, and the base 1 are on the same horizontal plane. The cutting device 4 is located on the upper surface of the first slide 2 and can move vertically up and down to adjust the distance between the cutting device 4 and the upper surface of the first slide 2. The crushing device 5 is located on the upper surface of the base 1 and above the cutting device 4. The crushing device 5 can move vertically up and down. The screening device 6 is located on the upper surface of the second slide 3. This integrated module recycling system for waste wind turbine blades is used to recycle waste wind turbine blades. At this time, the first slide 2 and the second slide 3 move horizontally in opposite directions, causing the cutting device 4 and the screening device 6 to move together, increasing the distance between the cutting device 4 and the screening device 6. After the horizontal in opposite directions of the first slide 2 and the second slide 3 stop, the crushing device 5 located above the cutting device 4 moves towards the upper surface of the base 1, causing the crushing device 5 to descend to the same horizontal plane as the cutting device 4, and the crushing device 5 is located between the cutting device 4 and the screening device 6. After the crushing device 5 descends to the same horizontal plane as the cutting device 4, it first passes through the cutting device... 4. The waste wind turbine blades are cut into blade fragments of a specified size. Then, the blade fragments are crushed into blade particles by the crushing device 5. The crushed blade particles are then screened by the screening device 6, thus completing the recycling of waste wind turbine blades. The entire integrated modular recycling system integrates the equipment used in the waste wind turbine blade recycling process. By the horizontal movement of the first slide table 2 and the second slide table 3, and the vertical movement of the cutting device 4 and the crushing device 5, the working state of the integrated modular recycling system can be flexibly adjusted. This eliminates the need to transfer the materials formed after each recycling step, reducing the consumption of manpower and material resources and the recycling cost of waste wind turbine blades, and improving the recycling efficiency. It solves the problem of high recycling cost and low recycling efficiency of waste wind turbine blades caused by the dispersed setting of recycling equipment in the existing technology. Moreover, the integrated modular recycling system can be easily moved to the waste wind turbine blade storage site, avoiding the handling of waste wind turbine blades, saving transportation costs, and improving the flexibility of waste wind turbine blade processing.

[0053] In one embodiment, in order to drive the first slide 2 and the second slide 3 to move in the horizontal direction, the integrated module recycling system for waste wind turbine blades further includes: a first driver 7 and a second driver 8.

[0054] The first driver 7 is used to drive the first slide 2 to move horizontally along the extension direction of the through groove;

[0055] The second driver 8 is used to drive the second slide 3 to move horizontally along the extension direction of the through groove.

[0056] like Figure 2 As shown, the first driver 7 and the second driver 8 are both mounted on the base 1. The first slide 2 and the second slide 3 move horizontally relative to the base 1. A through groove is formed on the base 1, with a large end and a small end. The first slide 2 is slidably mounted in the through groove and can slide in and out of the large end of the through groove. The second slide 3 is slidably mounted in the through groove and can slide in and out of the small end of the through groove. The first slide 2 is a portal frame with two parallel slide columns 21 and a slide beam 22 connecting the two slide columns 21. The second slide 3 is a T-shaped plate structure. The platform 3 has a horizontal plate 31 and a vertical plate 32. The vertical plate 32 of the second slide 3 can be embedded between the two slide columns 21 of the first slide 2. The first driver 7 is disposed between the groove wall of the through groove on the base 1 and the first slide 2 to drive the first slide 2 to slide in the through groove. The second driver 8 is disposed between the outer wall of the base 1 and the horizontal plate 31 of the second slide 3 to drive the second slide 3 to slide in the through groove. That is, the vertical plate 32 of the second slide 3 slides between the two slide columns 21 of the first slide 2. The first driver 7 and the second driver 8 are one of a cylinder, a hydraulic cylinder or a linear motor.

[0057] In one embodiment, the cutting device 4 includes: a cutting machine 41, a cutting tray 42, a third driver, and a plurality of cutting telescopic columns 43;

[0058] The cutting machine 41 is mounted on the cutting tray 42 and is used to cut waste wind turbine blades into blade fragments.

[0059] Multiple cutting telescopic columns 43 are vertically arranged on the first slide table 2, and each cutting telescopic column 43 can extend and retract vertically.

[0060] The cutting tray 42 is supported on the first slide table 2 by multiple cutting telescopic columns 43;

[0061] The third driver is mounted on the first slide 2 and is used to drive the cutting tray 42 to move up and down in the vertical direction.

[0062] The crushing device 5 includes: a crushing pallet 51, a crusher 52, a conveyor belt 53, a fourth drive, and multiple crushing telescopic columns 54;

[0063] The crusher 52 is mounted on the crushing tray 51 and is used to crush the blade fragments into blade particles.

[0064] The conveyor belt 53 is mounted on the crushing pallet 51 and is connected to the discharge port of the crusher 52. The conveyor belt 53 is used to convey the blade particles to the screening device 6.

[0065] Multiple crushing telescopic columns 54 are vertically arranged on the base 1, and each crushing telescopic column 54 can extend and retract vertically.

[0066] The crushing pallet 51 is supported on the base 1 by a plurality of crushing telescopic columns 54 and is located above the cutting pallet 42;

[0067] The fourth actuator is mounted on the base 1 and is used to drive the crushing pallet 51 to move up and down in the vertical direction.

[0068] like Figure 1 and Figure 3As shown, the base 1, cutting tray 42, and crushing tray 51 are arranged in layers and parallel to each other. The cutting tray 42 is located between the base 1 and the crushing tray 51. The first slide 2 and the second slide 3 are slidably arranged in the through groove on the base 1. Multiple cutting telescopic columns 43 vertically arranged on the first slide 2 support the cutting tray 42. When the third driver drives the cutting tray 42 to move vertically up and down, each cutting telescopic column 43 can extend and retract vertically. The cutting machine 41 arranged on the cutting tray 42 moves vertically up and down synchronously with the cutting tray 42. The crushing telescopic columns 54 vertically arranged on the base 1 support the crushing tray 51. When the fourth driver drives the crushing tray 51 to move vertically up and down, each crushing telescopic column 54 can extend and retract vertically. The third and fourth drivers are one of a cylinder, a hydraulic cylinder, or a linear motor. When recycling waste blades, the first driver... Device 7 drives the first slide 2 to slide within the through groove of the base 1 and slide out from the large end of the through groove. The second driver 8 drives the second slide 3 to slide between the two slide columns 21 of the first slide 2 and slide out from the small end of the through groove. In this way, the distance between the cutting device 4 on the first slide 2 and the screening device 6 on the second slide 3 increases. The third driver set on the first slide 2 drives the cutting pallet 42 to move vertically to a given position. The fourth driver set on the base 1 drives the crushing pallet 51 to move vertically so that the crushing pallet 51 and the cutting pallet 42 are on the same horizontal plane. In this way, the blade fragments cut by the cutter 41 on the cutting pallet 42 can be easily and quickly transferred to the crusher 52 on the crushing pallet 51 for crushing. The crushed blade particles are then conveyed to the screening device 6 for screening by the conveyor belt 53 set at the discharge port of the crusher 52.

[0069] like Figure 4As shown, the cutting machine 41 includes a gantry-type cutting frame 410, a vertical moving beam, and a cutting assembly. The cutting assembly includes a cutting blade 411 and a blade driver. The blade driver drives the cutting blade 411 to rotate. The gantry-type cutting frame 410 includes two vertical columns 412 and a cutting crossbeam 413. The two vertical columns 412 are arranged parallel to each other on the cutting support plate 42. The cutting crossbeam 413 is fixed to the top of the two vertical columns 412. The vertical moving beam is horizontally arranged and its two ends are slidably mounted on the two vertical columns 412 respectively. The vertical moving beam can move along the vertical columns 412. The cutting component moves up and down along the extension direction of the vertical column 412. The cutting component is slidably mounted on the vertical moving beam and can move along the extension direction of the vertical moving beam. When cutting waste wind turbine blades, the blade driver of the cutting component drives the cutting blade 411 to rotate. The vertical moving beam moves along the extension direction of the vertical column 412 to adjust the cutting depth. The cutting component moves along the extension direction of the vertical moving beam to complete the cutting of waste wind turbine blades through the cutting blade 411. The blade fragments formed by cutting are crushed into blade particles by the crusher 52. The conveyor belt 53 conveys the blade particles to the screening device 6 for screening.

[0070] To ensure that the cut blade fragments are of uniform length and facilitate subsequent crushing by the crusher 52, the integrated module recycling system for waste wind turbine blades also includes a marking device 9, which is set on the cutting tray 42 and used to mark the cutting lines on the waste wind turbine blades.

[0071] The marking device 9 includes: a marking heating wire 91 and a pair of clamping plates 92;

[0072] A pair of clamping plates 92 are slidably disposed on the cutting tray 42 for clamping waste wind turbine blades;

[0073] A marking heating wire 91 is disposed on any of the clamping plates 92 and is used to heat the contact area with the waste wind turbine blade to mark the cutting line.

[0074] The cutting tray 42 has a limiting groove 420, and a pair of clamping plates 92 are slidably disposed in the limiting groove 420.

[0075] The marking device 9 further includes: a plurality of elastic elements 93;

[0076] Multiple elastic elements 93 are provided between each clamping plate 92 and the groove wall of the limiting slide 420, and the clamping plate 92 is pushed by the elastic elements 93 to clamp the waste wind turbine blade.

[0077] The limiting slide 420 is set in front of the feed inlet of the cutting machine 41. The extension direction of the limiting slide 420 is perpendicular to the feeding direction of the waste wind turbine blade. A pair of clamping plates 92 are slidably set in the limiting slide 420. The pair of clamping plates 92 are pushed by the elastic element 93 set between each clamping plate 92 and the groove wall of the limiting slide 420 to clamp the waste wind turbine blade. When the clamping plates 92 clamp the waste wind turbine blade, the marking heating wire 91 set on the clamping plate 92 comes into contact with the waste wind turbine blade, which can heat the part in contact with the waste wind turbine blade and mark the cutting line on the waste wind turbine blade to ensure that the blade powder is cut according to the cutting line in the future. The elastic element 93 is a spring.

[0078] The crusher 52 crushes the blade fragments into blade particles, and the conveyor belt 53 set at the discharge port of the crusher 52 conveys the crushed particles to the screening device 6. The screening device 6 includes a screening machine and a dust cover 61.

[0079] The screening machine is set on the second slide table 3 and is used to screen the blade particles formed after being crushed by the crushing device 5.

[0080] The dust cover 61 has a particle inlet corresponding to the feed port of the screening machine and a particle outlet corresponding to the discharge port of the screening machine. The dust cover 61 is disposed on the second slide table 3 and is used to cover the screening machine.

[0081] The blade particles enter the screening machine through the particle inlet and the screening machine feed inlet for screening. The screened blade particles are discharged through the screening machine discharge outlet and particle outlet.

[0082] like Figure 1 As shown, the integrated module recycling system for waste wind turbine blades also includes multiple wheels 10 mounted near the ground end of the base 1. These wheels allow for easy movement of the integrated module recycling system to the waste wind turbine blade storage location. To ensure stable operation, the system also includes multiple adjustable support legs 12. These support legs 12 are located near the ground end of the base 1, at the ground-facing end of the slide beam 22 of the first slide 2, and at the ground-facing end of the cross plate 31 of the second slide 3. They support the first slide 2 when its large end is stationary and the second slide 3 when its small end is stationary. A power supply 11 is also provided on the base 1, supplying power to the cutter 41, crusher 52, and screening machine.

[0083] The integrated modular recycling system for waste wind turbine blades provided by this invention includes a cutting device mounted on a first slide, a crushing device mounted on a base, and a screening device mounted on a second slide. Both the first and second slides can move horizontally towards each other or horizontally away from each other within a groove on the base. During the horizontal movement of the first slide within the groove, it drives the cutting device to move horizontally synchronously, and during the horizontal movement of the second slide within the groove, it drives the screening device to move horizontally synchronously. During the recycling of waste wind turbine blades, the first and second slides drive the cutting and screening devices to move horizontally away from each other, increasing the distance between them. Then, the crushing device mounted on the base moves vertically downwards between the cutting and screening devices, bringing them to the same horizontal plane. Thus, after the cutting device completes the waste wind turbine blade recycling process... After the old wind turbine blades are cut, the resulting blade fragments can be directly and quickly fed into a crushing device for crushing. After crushing, the resulting blade particles are then screened by a screening device. This integrated modular recycling system for waste wind turbine blades integrates all the devices used in the waste wind turbine blade recycling process. By moving the first and second slides horizontally and the cutting and crushing devices vertically, the recycling process of waste wind turbine blades can be flexibly adjusted. This eliminates the need to transfer the materials generated after each recycling step, greatly reducing the consumption of manpower and material resources and the recycling cost of waste wind turbine blades. It also improves the recycling efficiency of waste wind turbine blades and solves the problem of high recycling cost and low recycling efficiency caused by the dispersed recycling equipment in existing technologies.

[0084] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the embodiments of the present invention will not describe the various possible combinations separately.
