Description

Technical Field

[0001] This utility model relates to the field of blade recycling and processing technology, and more specifically to the field of a device for recycling and processing waste blades of wind turbine generator sets. Background Technology

[0002] Waste wind turbine blades typically contain fiber-reinforced materials, plastic polymers, sandwich materials, and coatings. These materials are difficult to degrade in the natural environment, and landfill disposal leads to land occupation and environmental pollution. Incineration produces harmful gases, exacerbating air pollution. The realization of blade recycling and comprehensive utilization can not only solve the above problems, but also allow these recycled materials to be reused in the manufacture of new products, reducing the demand for native resources.

[0003] Patent publication number CN222712587U, entitled "A Crushing and Recycling Device for Waste Wind Turbine Blades," discloses the following: A crushing and recycling device for waste wind turbine blades includes a main body with an opening on its exterior. A fixed rod is fixedly connected inside the main body, and a rotating plate is rotatably connected to the outside of the fixed rod. A sliding groove is formed inside the rotating plate, and a sieve plate is slidably connected inside the groove. A pull rod is fixedly connected to the outside of the sieve plate. A fixed block is fixedly connected to the outside of the main body, and a second motor is fixedly connected to the outside of the fixed block. A rotating shaft is fixedly connected to one side of the second motor, and a stop plate is fixedly connected to the outside of the rotating shaft. The device vibrates by the rotating plate colliding with the device externally via a vibration mechanism, which, in conjunction with the sieve plate, sieves the blades. Small blades fall through the sieve holes into a second collection box, while larger blades slide into a first collection box. For even larger blades that cannot pass through the opening, the sieve plate is pulled out, exposing the hollow structure of the rotating plate, allowing the blades to fall out. This simplifies blade sorting and improves recycling efficiency.

[0004] Patent CN220310614U, entitled "A Wind Power Blade Recycling Device," discloses the following: A wind power blade recycling device, relating to the field of crushing and recycling equipment, includes a crushing and recycling box. A base is fixedly installed on the top of the crushing and recycling box, and a protective shell is fixedly installed on the top of the base. A drive motor is fixedly installed inside the protective shell. A discharge pipe is fixedly installed at the bottom left end of the crushing and recycling box, and a feed hopper is fixedly installed on the top of the crushing and recycling box and to the right of the protective shell. This invention involves feeding waste wind power blades into the feed hopper, simultaneously activating the drive motor to rotate a rotating shaft. The rotating shaft drives gear one to rotate, gear one drives gear two to rotate, gear two drives gear three to rotate, and gear three drives a rotating rod to rotate. This, in turn, causes the rotating blades on the outer wall of the rotating rod to rotate, thus initially crushing the waste blades. Under the weight of the waste blades themselves, the initially crushed blades fall into the crushing and recycling box.

[0005] The aforementioned patents and existing technologies may employ a single crushing method (such as only a pair of parallel crushing rollers or only one crushing chamber). For tough, long-fiber wind turbine blade composite materials, this single crushing method is prone to jamming and clogging, requiring frequent shutdowns for cleaning, resulting in low processing efficiency. Simultaneously, the output particle size is uneven, with coarse blocks mixed with fine powder, failing to meet the raw material particle size requirements for subsequent sorting or resource utilization.

[0006] Therefore, we propose a device for recycling and processing waste blades from wind turbine generator sets. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0028] This utility model provides a device for recycling and processing waste blades of wind turbine generator sets, including a crushing box 1 with an open top, a crushing component set at the top of the crushing box 1, a cone crushing component set at the bottom of the crushing box 1, a dust removal system set on the upper side wall of the crushing box 1, a discharge port component set at the bottom of the crushing box 1, and a controller 10 set on the front side of the crushing box 1 for controlling the crushing component and the cone crushing component.

[0029] In one embodiment, the crushing assembly includes a first crushing roller 11 and a second crushing roller 110 arranged side by side at the top of the crushing chamber 1. Both ends of the first crushing roller 11 and the second crushing roller 110 are rotatably mounted on the side wall of the crushing chamber 1 via bearings. The first crushing roller 11 and the second crushing roller 110 rotate in opposite directions, with the first crushing roller 11 located on the left and the second crushing roller 110 located on the right. The first crushing roller 11 rotates clockwise and the second crushing roller 110 rotates counterclockwise. Both the first crushing roller 11 and the second crushing roller 110 are provided with a number of crushing teeth.

[0030] In one embodiment, the first crushing roller 11 and the second crushing roller 110 are both provided with gears 111 extending from the same end of the side wall of the crushing box 1. The two gears 111 mesh with each other. The other end of the crushing box 1 is provided with a servo motor 102 that drives the second crushing roller 110 to rotate.

[0031] In one embodiment, a protective shell 103 for protecting the two gears 111 is provided on the outer wall of the crushing chamber 1.

[0032] In one embodiment, the crushing box 1 is provided with a crushing trough 104, the discharge port assembly is a plurality of discharge troughs 105 provided on the bottom surface of the crushing trough 104, the conical crushing assembly is a conical crushing roller 120 rotatably provided in the crushing trough 104, the bottom lower surface of the crushing box 1 is provided with a rotary motor 12 that drives the conical crushing roller 120 to rotate, and a plurality of crushing teeth are evenly distributed on the outer wall of the conical crushing roller 120.

[0033] In one embodiment, the pulverizing tank 104 has a conical cross-section.

[0034] In one embodiment, a feed hopper 101 is provided at the opening at the upper end of the crushing box 1.

[0035] Working principle: Pre-treated waste blade fragments are fed into the crushing box 1 from the feed hopper 101. The device is started, and the controller 10 controls the servo motor 102 and the dust extraction fan 13 to start working. The servo motor 102 directly drives the second crushing roller 110 to rotate. Since the gears 111 on the left end of the first crushing roller 11 and the second crushing roller 110 mesh with each other, the first crushing roller 11 rotates in the opposite direction. The two rollers rotate relative to each other, like "scissors" to shear, squeeze and tear the blade material falling between them, completing the first stage of primary crushing, breaking large pieces of material into smaller pieces. The material after primary crushing falls into the crushing trough 104 below under the action of gravity. At the same time, the controller 10 controls the rotating motor 12 to work, driving the conical crushing roller 120 to rotate at high speed in the conical crushing trough 104. Since the cross-section of the crushing trough 104 is conical, the gap between it and the conical crushing roller 120 gradually decreases from top to bottom. The material is subjected to increasingly intense compression, grinding and shearing in this gap, and is further crushed into finer particles or fiber powder. When the particle size of the material is crushed to a size smaller than the gap of the discharge chute 105, it is discharged from the crushing box 1 through the discharge chute 105 under the action of gravity and falls into the collection device below, such as the collection box, thus completing the entire crushing process.

[0036] In one embodiment, the dust removal system includes a channel 106 disposed on the inner side wall of the pulverizing chamber 1 and an intercepting net 107 disposed in the channel 106, the intercepting net 107 being made of stainless steel.

[0037] It also includes a dust extraction fan 13 installed on the outer wall of the crushing box 1. The suction end of the dust extraction fan 13 is connected to a dust extraction hood 130, which is fixedly connected to the crushing box 1 and communicates with the through groove 106.

[0038] The controller 10 is electrically connected to an external power source, and is also electrically connected to the vacuum cleaner fan 13, the servo motor 102, and the rotary motor 12.

[0039] Throughout the crushing process, the dust extraction fan 13 operates continuously, generating negative pressure at the dust extraction hood 130 and the connected channel 106, forming a directional airflow inside the crushing chamber 1. The light dust and short fibers generated during crushing are adsorbed by this airflow and pass through the stainless steel intercepting mesh 107, which blocks large pieces of material that have not been crushed properly. The materials are then sucked into the dust extraction hood 130 and finally enter the collection system of the dust extraction fan 13, such as a bag filter. This process achieves simultaneous crushing and dust removal, effectively suppressing dust dispersion, improving the working environment, and recovering valuable dust materials.

[0040] It should be noted that the pre-treated waste blade fragments are fed into the crushing box 1 from the feed hopper 101. The device is started, and the controller 10 controls the servo motor 102 and the dust extraction fan 13 to start working. The servo motor 102 directly drives the second crushing roller 110 to rotate. Since the gears 111 on the left end of the first crushing roller 11 and the second crushing roller 110 mesh with each other, the first crushing roller 11 rotates in the opposite direction. The two rollers rotate relative to each other, like "scissors" to shear, squeeze and tear the blade material falling between them, completing the first stage of primary crushing, breaking large pieces of material into smaller pieces. The material after primary crushing falls into the crushing trough 104 below under the action of gravity. At the same time, the controller 10 controls the rotating motor 12 to work, driving the conical crushing roller 120 to rotate at high speed in the conical crushing trough 104. Since the cross-section of the crushing trough 104 is conical, the gap between it and the conical crushing roller 120 gradually decreases from top to bottom. Within this gap, the material is subjected to increasingly intense compression, grinding, and shearing, further pulverizing it into finer particles or fiber powder. When the particle size of the material is pulverized to a size smaller than the gap in the discharge chute 105, it is discharged from the crushing chamber 1 under gravity through the discharge chute 105 and falls into the collection device below, such as the collection box, completing the entire crushing process. Throughout the crushing process, the dust extraction fan 13 operates continuously, generating negative pressure at the dust extraction hood 130 and the communicating channel 106, forming a directional airflow inside the crushing chamber 1. The light dust and short fibers generated during crushing are adsorbed by this airflow and pass through the stainless steel intercepting mesh 107 (which blocks large pieces of uncrushed material) and are sucked into the dust extraction hood 130. Finally, they enter the collection system of the dust extraction fan 13, such as a bag filter. This process achieves simultaneous crushing and dust removal, effectively suppressing dust dispersion, improving the working environment, and recovering valuable dust materials.
