Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine blade crushing devices, specifically referring to a graded processing device adapted to the crushing of wind turbine blades of various sizes. Background Technology

[0002] As the global energy structure shifts towards clean energy, wind power, as a core component of renewable energy, has seen its installed capacity grow rapidly. Wind turbine blades, as the core components of wind power equipment, typically have a design life of 20-25 years, leading to a large-scale demand for the processing of retired wind turbine blades, which is increasing year by year. The material characteristics and dimensional diversity of wind turbine blades present significant technical challenges to their crushing and processing, and the physical and mechanical properties of different materials vary considerably. In terms of size, influenced by wind turbine models, the blade length spans a wide range. Existing wind turbine blade crushing and grading devices, limited by their "single-size adaptation" technology, are unable to meet the processing needs of retired blades with "multiple sizes and materials."

[0003] The fixed feed inlet size of the existing equipment prevents large blades from entering smoothly, requiring them to be pre-cut into smaller pieces, which increases labor costs and process complexity; while small blades may cause jamming or deviation due to excessive gaps, affecting continuous operation efficiency.

[0004] Furthermore, if parameters such as the blade spacing and rotation speed of the crusher are optimized for a single size, problems such as over-crushing or insufficient crushing may occur when processing blades of different thicknesses or stiffnesses. In addition, if the screen aperture or airflow separation parameters of the screening equipment are fixed, it will lead to the mixing of crushed particles of multiple sizes, affecting the purity of subsequent material separation. Utility Model Content

[0005] The technical problem this invention aims to solve is that the wind turbine blade crushing and processing device has poor size adaptability, insufficient feeding compatibility, and an imbalance between crushing efficiency and energy consumption.

[0006] The technical solution adopted by this utility model is as follows:

[0007] This utility model proposes a grading and processing device for crushing wind turbine blades of various sizes, including a crushing and processing machine housing with an opening at the top and a discharge hopper at the bottom. It also includes a dynamically adjustable processing unit, which includes sliding grooves on both sides of the crushing and processing machine housing. A U-shaped slide is slidably mounted on the sliding grooves, and a motor passes through one side of the U-shaped slide. A crushing roller that rotates inside the U-shaped slide is fixed to the output shaft of the motor.

[0008] Furthermore, the U-shaped carriage has two sets of rollers mirror-arranged on the sliding groove, and the two sets of crushing rollers rotate in opposite directions.

[0009] Furthermore, cylinders are inserted through both sides of the crushing machine housing, and the output end of the cylinder is fixedly connected to the U-shaped slide. A PLC controller is fixedly connected to the outer wall of the crushing machine housing for controlling and adjusting the cylinders.

[0010] Furthermore, a feed cylinder is fixedly connected to the upper part of the crushing and processing machine casing. Two sets of mirror-arranged U-shaped frames are provided above the feed cylinder. A clamping and conveying device is arranged inside the U-shaped frame along the feeding direction of the wind turbine blade. The clamping and conveying device includes three sets of guide rollers arranged at intervals from top to bottom inside the U-shaped frame. The diameter of the three sets of guide rollers increases progressively from top to bottom. The center distance between two adjacent sets of guide rollers is adapted to the thickness gradient of the wind turbine blade, forming a multi-stage clamping and positioning from top to bottom, which restricts the displacement of the blade in the subsequent crushing process.

[0011] Furthermore, a support base is fixedly connected to the upper part of the feeding square cylinder, and a guide rod fixedly connected to the outside of the U-shaped frame is movably inserted and plugged into the support base. A tensioning spring is sleeved on the guide rod.

[0012] Furthermore, the lower part of the discharge hopper is connected to a screen box, and multiple sets of vertically distributed pull grooves are opened on the side wall of the screen box, and screen frames with different apertures are pulled out on each set of pull grooves.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. A dynamically adjustable processing unit is set up to adjust the position of the U-shaped carriage by mechanical adjustment to adapt to the feed inlet spacing, ensuring that blades of different widths can enter smoothly, and the drive adjustment is carried out by a PLC controller in conjunction with a cylinder.

[0015] 2. A clamping conveyor device is adopted, with guide rollers installed on both sides. The spring preload adapts to changes in blade thickness, avoiding blade damage or equipment jamming caused by rigid collisions.

[0016] 3. The screen box adopts a drawer-type design, which allows for quick replacement of screen frames with different aperture sizes by pulling them out, to meet the screening needs of materials with different particle sizes. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0025] Example 1:

[0026] like Figure 1 , 3 As shown in Figure 4, the present invention proposes a grading and processing device for crushing wind turbine blades of various sizes, including a crushing and processing housing 1. The upper part of the crushing and processing housing 1 is provided with an opening 11, and the lower part of the crushing and processing housing 1 is connected to a discharge hopper 12. It also includes a dynamically adjustable processing unit. The dynamically adjustable unit includes sliding grooves 2 on both sides of the crushing and processing housing 1. A U-shaped slide 21 is slidably provided on the sliding grooves 2. A motor 22 passes through one side of the U-shaped slide 21. A crushing roller 23 is fixedly connected to the output shaft of the motor 22 and rotates inside the U-shaped slide 21.

[0027] Two sets of U-shaped slides 21 are mirror-arranged on the sliding groove 2, and the two sets of crushing rollers 23 rotate in opposite directions; cylinders 3 pass through both sides of the crushing machine housing 1, and the output end of the cylinders 3 is fixedly connected to the U-shaped slides 21; a PLC controller 31 is fixedly connected to the outer wall of the crushing machine housing 1 for controlling and adjusting the cylinders 3.

[0028] It should be noted that during the crushing and processing of wind turbine blades inside the crushing and processing machine casing 1, the motor 22 drives the crushing rollers 23 to rotate. The two sets of crushing rollers 23 rotate to crush the material. Depending on the size of the blades, the cylinder 3 can be controlled and adjusted by the PLC controller 31. The output end of the cylinder 3 extends and retracts, pushing the U-shaped slide 21 to slide on the sliding groove 2, thereby adjusting the distance between the two sets of crushing rollers 23.

[0029] Example 2:

[0030] like Figure 2 , 5 As shown, a feed cylinder 4 is fixedly connected to the upper part of the crushing and processing machine casing 1. Two sets of mirror-arranged U-shaped frames 41 are provided above the feed cylinder 4. A clamping and conveying device is arranged inside the U-shaped frame 41 along the feeding direction of the wind turbine blade. The clamping and conveying device includes three sets of guide rollers 42 arranged at intervals from top to bottom inside the U-shaped frame 41. The roller diameter of the three sets of guide rollers 42 increases stepwise from top to bottom. The center distance between two adjacent sets of guide rollers 42 is adapted to the thickness gradient of the wind turbine blade, forming a multi-stage clamping and positioning from top to bottom, which restricts the displacement of the blade in the subsequent crushing process. A support base 5 is fixedly connected to the upper part of the feed cylinder 4. A guide rod 51 fixedly connected to the outside of the U-shaped frame 41 is movably inserted into the support base 5. A tensioning spring 52 is sleeved on the guide rod 51.

[0031] During the feeding process of wind turbine blades from the feed cylinder 4, the guide roller 42 clamps and guides them. According to the change of roller diameter, the guide roller 42 gradually increases the preload from top to bottom. Under the action of the elastic potential energy of the top spring 52, the guide rod 51 can be pushed to slide on the support seat 5, flexibly adjusting the clamping position of the U-shaped frame 41.

[0032] like Figure 1 , 2 As shown, the lower part of the discharge hopper 12 is connected to a screen box 6. The side wall of the screen box 6 has multiple sets of vertically distributed pull slots 61. Each set of pull slots 61 is equipped with a screen frame 62 with different aperture. In actual use, different screen frames 62 are selected according to the size characteristics of the wind turbine blade fragments and are slid into the pull slots 61 for use, which facilitates switching operations.

[0033] The above is the entire usage process of a graded treatment device adapted to the crushing of wind turbine blades of various sizes.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
