[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The fan blade material processing device 100 of the embodiment of the present invention includes a dismantling furnace 1, a disassembling rack 2 and a fiber claw 3. The dismantling furnace 1 has a feeding channel 101 and a discharge channel 102. The feeding channel 101 is used for blades to fall into the dismantling furnace 1. The furnace wall of the dismantling furnace 1 is provided with a jet port 103. The jet port 103 is used to spray depolymerization liquid toward the blades falling in the dismantling furnace 1 to depolymerize the organic matter in the blades and separate the fibers in the blades. The disassembling rack 2 is arranged in the dismantling furnace 1 and is located below the feeding channel 101. The disassembling rack 2 is used to collide with the falling blades to break the blades. The fiber claw 3 is arranged in the discharge channel 102 and is used to grab the fibers in the depolymerization liquid when the depolymerization liquid is discharged from the discharge channel 102.

[0021] When the fan blade material processing device 100 according to an embodiment of the present invention is in use, discarded fan blades are fed into the dismantling furnace 1 through a discharge channel 101. Furnace 1 is provided with a jet nozzle 103. Once the blades enter the furnace 1, jet nozzle 103 sprays a depolymerization liquid. This depolymerization liquid decomposes the organic polymers in the blades, separating the fiber reinforcement and plastic polymer components of the composite material.

[0022] During the falling process of the blades, the disassembly rack 2 located below the discharge channel 101 will collide with the falling blades. This collision can break the hard part of the blades, further help the depolymerization liquid penetrate into the blade material, and at the same time make the blade structure looser, which is convenient for the subsequent separation process.

[0023] When the depolymerization liquid and the crushed blade material move through the discharge channel 102, the fiber claws 3 in the channel will grab and separate the fibers in the depolymerization liquid. In this way, the fibers can be recycled, and the remaining decomposition products can be discharged through the discharge channel 102.

[0024] The fan blade material processing device 100 of the embodiment of the present invention can effectively reduce environmental pollution problems caused by landfill or incineration of garbage through this processing device, because these methods often produce harmful gases and leachate. The present invention can effectively recycle fibers in the blades, and these fibers can be reused in other industrial fields, thereby reducing resource waste. Compared with traditional processing methods, this device can automatically disintegrate the blades and separate the fibers, thereby improving processing efficiency. Through the automated processing process, the time and risk of workers directly contacting waste are reduced, thereby protecting the health and safety of workers.

[0025] In some embodiments, the disassembling rack 2 is divided into multiple layers, and the multiple layers of disassembling racks 2 are arranged at intervals along the height direction of the disassembling furnace 1 .

[0026] Multiple layers of disassembly racks 2 are spaced apart along the height of the disassembly furnace 1, with each layer positioned at a different height to accommodate the different stages of blade processing within the disassembly furnace 1. When a blade enters the disassembly furnace 1 from the loading channel, it first encounters the highest layer of disassembly racks 2. As the blade falls, it collides with the different layers of disassembly racks 2, gradually breaking it apart. This ensures that the blade is subjected to uniform and sufficient force during the disassembly process, helping the disassembly liquid to better penetrate all parts of the blade.

[0027] Because the blades are broken down at multiple levels, the depolymerization liquid comes into contact with the blade material more evenly and thoroughly, thereby improving the depolymerization efficiency of the organic matter. The multi-layered design of the depolymerization rack 2 provides greater flexibility. The position and force of the depolymerization rack 2 can be adjusted to suit different processing requirements, depending on the size and material properties of the blades. The staged decomposition of the blades reduces damage to the recyclable materials within the blades, especially for fragile fibrous materials, helping to maintain their structural integrity and thus improving the quality of the recycled material.

[0028] In some embodiments, the dismantling rack 2 includes a plurality of dismantling rods 201 spaced apart along the width direction of the dismantling furnace 1 , and the dismantling rods 201 are tilted downward.

[0029] A plurality of splitting rods 201 are installed in the splitting frame 2. These splitting rods 201 are evenly distributed along the width direction of the disintegration furnace 1 to ensure that the blades can be split at any position in the disintegration furnace 1. The downwardly inclined design of the splitting rods 201 allows the blades to be continuously collided and cut by the splitting rods 201 during their natural sliding down process under the action of gravity. This arrangement helps to increase the crushing area of ​​the blades, thereby crushing the blades more effectively. When the blades enter the disintegration furnace 1 from the feeding channel, the downwardly inclined splitting rods 201 will exert dynamic force on the blades, causing the blades to be hit at multiple points at the same time, accelerating the crushing and disintegration of the blades.

[0030] The oblique downward tilt setting of the separating rod 201 makes the movement trajectory of the blades in the disintegration furnace 1 more reasonable, which helps to crush the blades more quickly and thoroughly, thereby improving the efficiency of the entire processing process. The uniform distribution and oblique downward tilt setting of the separating rod 201 ensure the uniform treatment of the blades during the disintegration process and reduce potential damage to the blade material. The dynamic crushing action of the separating rod 201 helps the depolymerization liquid to penetrate deeper into the blade material, thereby improving the depolymerization effect of the organic matter and facilitating subsequent fiber separation. The layout and tilt setting of the separating rod 201 help to optimize the fluidity and distribution of the material, making the movement of the blades in the disintegration furnace 1 smoother and reducing the possibility of material congestion. By crushing the blades more efficiently, the amount of depolymerization liquid and processing time can be reduced, thereby reducing energy consumption and costs.

[0031] In some embodiments, the density of the separating rods 201 in the separating rack 2 gradually increases from top to bottom.

[0032] The density of the splitting rods 201 in the upper area of ​​the splitting frame 2 is relatively low, and as the height decreases, the density of the splitting rods 201 gradually increases. This design allows the blades to encounter splitting rods 201 of different densities at different heights in the disintegration furnace 1. When the blades first enter the disintegration furnace 1, due to the low density of the splitting rods 201, the forces acting on the blades are relatively dispersed, which helps to initially crush the blades without causing excessive damage to the blades. As the blades continue to fall, the density of the splitting rods 201 gradually increases, and the forces acting on the blades also increase accordingly. In this way, as the blades fall, the crushing force they are subjected to gradually increases, thereby achieving more thorough crushing.

[0033] The gradual increase in the density of the splitting rod 201 can more effectively crush blade parts of different hardness and structure, thereby improving the overall crushing efficiency. The blades go through different crushing stages in the disintegration furnace 1. The initial crushing of the upper part and the thorough crushing of the lower part require different forces. The density design of this splitting rod 201 can adapt to the needs of these different stages. By gradually increasing the force during the blade crushing process, damage to recyclable materials (especially fibers) can be reduced, thereby reducing material loss. Due to the gradual increase in the density of the splitting rod 201, it helps the blades to slide down more smoothly in the disintegration furnace 1, reducing the reduction in processing efficiency caused by material congestion. The gradually increasing density of the splitting rod 201 helps to better mix with the depolymerization liquid while the blades are crushed, thereby improving the depolymerization effect of organic matter and facilitating subsequent fiber separation and recovery.

[0034] In some embodiments, there are multiple injection ports 103, and the multiple injection ports 103 are arranged at intervals along the height direction of the disintegration furnace 1. At least one injection port 103 sprays the depolymerization liquid obliquely upward, at least one injection port 103 sprays the depolymerization liquid horizontally, and at least one injection port 103 sprays the depolymerization liquid obliquely downward.

[0035] For example, 2 to 5 injection ports 103 are provided.

[0036] The layout of the injection port 103 in the disintegration furnace 1 is diverse, including those that inject upward obliquely, those that inject horizontally, and those that inject downward obliquely. Such a layout ensures that the depolymerized liquid can process the falling blades from different angles and directions.

[0037] At least one jet 103 sprays the depolymerization liquid obliquely upward, which helps to pre-treat the blades as they enter the disintegration furnace 1 and decompose their surfaces. At least one jet 103 sprays the depolymerization liquid horizontally, which helps to evenly decompose the blades within the disintegration furnace 1. At least one jet 103 sprays the depolymerization liquid obliquely downward, which helps to further decompose the internal structure of the blades as they fall.

[0038] By spraying the depolymerization liquid at multiple angles, different parts of the blade can be decomposed more comprehensively, thereby improving the overall decomposition efficiency. Spraying in different directions can ensure that the depolymerization liquid can penetrate into every corner of the blade, enhancing the effect of the depolymerization liquid. Multi-angle spraying helps to achieve uniform decomposition of the blade and avoid material waste caused by local over-decomposition. The injection ports 103 with different injection directions can carry out targeted depolymerization according to the processing requirements of the blades at different positions in the disintegration furnace 1, thereby improving the adaptability of the processing process. By precisely controlling the operation of each injection port 103, the quality of the processed blades can be improved and the value of the recycled materials can be guaranteed. Since the injection of the depolymerization liquid is more efficient, the amount of depolymerization liquid used can be reduced, thereby reducing energy consumption and costs.

[0039] In some embodiments, a liquid return port 104 is provided at the bottom of the furnace wall of the disintegration furnace 1 , and the liquid return port 104 is connected to the injection port 103 through a liquid return pump.

[0040] A liquid return port 104 at the bottom of the disintegration furnace 1 is used to collect unreacted depolymerization liquid and liquid components separated from the blades during the processing process. This liquid may contain unreacted depolymerization agent, water, and other recoverable chemicals. Liquid return port 104 is connected to injection port 103 via a liquid return pump, forming a circulation system for the depolymerization liquid. The liquid return pump pumps the collected depolymerization liquid back to injection port 103 of the disintegration furnace 1 for reuse.

[0041] Recycling the depolymerization liquid significantly reduces the need for new depolymerization liquid, saving resources and costs. Recycling the depolymerization liquid helps reduce waste generation and minimize environmental impact. Pure depolymerization liquid more effectively decomposes organic matter in the leaves, improving treatment efficiency. The circulation system maintains a stable concentration and performance of the depolymerization liquid, ensuring consistency and stability during the treatment process. By reducing the consumption of fresh depolymerization liquid, operating costs can be reduced during the treatment process.

[0042] In some embodiments, the injection port 103 is provided with a flow regulating valve to adjust the injection flow of the injection port 103 .

[0043] A flow control valve is installed at each injection port 103, independently adjusting the flow rate of the depolymerization liquid at each injection port 103. Operators can adjust the flow rate at each injection port 103 based on the real-time needs of the process and the characteristics of the blades. The flow control valve allows the operator to dynamically control the injection volume of the depolymerization liquid, thereby achieving real-time adjustment of the blade depolymerization process.

[0044] By precisely controlling the flow rate of the depolymerization liquid, a more uniform and thorough depolymerization process can be ensured, improving the depolymerization effect of organic matter in the blades and thus enhancing the treatment quality. The flow control valve can reduce the waste of depolymerization liquid by spraying the appropriate amount of depolymerization liquid only when needed, thereby optimizing resource utilization. Different blade materials and structures may require different amounts of depolymerization liquid, and the flow control valve can provide the necessary flexibility to adapt to different treatment needs. By adjusting the flow rate of the depolymerization liquid in real time, the treatment speed can be accelerated and the efficiency of the entire treatment process can be improved. The flow control valve helps reduce the cost of using depolymerization liquid by avoiding overuse and unnecessary waste. Operators can precisely control the flow rate of depolymerization liquid at each injection port 103 based on the actual blade treatment situation, achieving a more refined treatment process. The flow control valve can also quickly close the injection port 103 in an emergency, improving the safety of the treatment process.

[0045] In some embodiments, the fiber claws 3 include multiple layers, and the multiple layers of fiber claws 3 are spaced apart along the extending direction of the discharge channel 102 .

[0046] For example, the fiber claws 3 are provided in 2 to 3 layers.

[0047] Multiple layers of fiber claws 3 are spaced apart along the extension of discharge channel 102, with each layer of fiber claws 3 positioned at a different location. This allows the multiple layers of fiber claws 3 to continuously grab and separate the fibers as the depolymerization liquid and crushed blade material flow through discharge channel 102. As the depolymerization liquid and crushed blade material flow from disintegration furnace 1 into discharge channel 102, each layer of fiber claws 3 grabs the fibers once, gradually separating them from the depolymerization liquid. The spaced-apart arrangement of fiber claws 3 ensures sufficient space and time during the fiber separation process, allowing for efficient fiber separation and collection.

[0048] The design of the multi-layer fiber claws 3 can ensure that the fibers get multiple opportunities to be grabbed and separated during the flow of the depolymerization liquid, thereby improving the fiber separation efficiency. The settings of different layers of fiber claws 3 can be adjusted according to the characteristics of different types of blade materials and fibers to adapt to different separation needs. Through the design of the multi-layer fiber claws 3, the structural integrity and recycling quality of the fibers can be better maintained, and the utilization value of the recycled fibers can be improved. The continuous separation process of the multi-layer fiber claws 3 can speed up the fiber recovery rate and reduce processing time. The fiber claws 3 arranged at intervals help reduce damage to the fibers during the separation process, maintain the physical and chemical properties of the fibers, and ensure the quality of the fibers. The design of the multi-layer fiber claws 3 makes the entire separation system more flexible and can be adjusted and optimized according to actual production needs.

[0049] In some embodiments, the fiber claw 3 includes a plurality of grabbing bars 301 arranged at intervals, and the grabbing bars 301 in two adjacent layers of fiber claws 3 are arranged in a staggered manner.

[0050] The grab bars 301 in two adjacent layers of fiber claws 3 are staggered, forming a grid-like structure. This staggered arrangement ensures that each fiber has a higher probability of being captured during the fiber separation process. As the depolymerization liquid and shredded blade material flow through the discharge channel 102, the staggered grab bars 301 can grab fibers from multiple directions, increasing the likelihood of fiber capture.

[0051] The staggered arrangement of the grab bars 301 can significantly improve the fiber separation rate, ensuring that more fibers are effectively collected. The staggered grab bars 301 can grab fibers at different heights and angles, thereby improving the grabbing effect and reducing fiber omission. The staggered grab bars 301 help to more completely recover fiber materials, maintain the structure and properties of the fibers, and increase the utilization value of the recycled fibers. Because the grab bars 301 can grab fibers more effectively, the speed of the entire fiber separation process is increased. The staggered arrangement of the grab bars 301 helps to reduce damage to the fibers during the separation process, maintain the physical and chemical properties of the fibers, and ensure the quality of the fibers.

[0052] In some embodiments, a cyclone 4 is provided at the outlet of the discharge channel 102 to separate the depolymerized liquid from the fibers. The cyclone 4 has a first outlet 401 and a second outlet 402. The first outlet 401 is used to discharge the separated depolymerized liquid, and the second outlet 402 is used to discharge the separated fibers. A liquid inlet 105 is provided at the top of the furnace wall of the disintegration furnace 1. The liquid inlet 105 is connected to the first outlet 401 to return the separated depolymerized liquid to the disintegration furnace 1.

[0053] The cyclone 4 is a device that uses centrifugal force to separate substances. When the depolymerized liquid and the crushed blade material enter the cyclone 4, the centrifugal force pushes the denser fibers toward the periphery of the cyclone 4, while the less dense depolymerized liquid is pushed toward the center.

[0054] The cyclone 4 has two outlets: a first outlet 401, located at the bottom or side of the cyclone 4, for discharging the separated depolymerized liquid; a second outlet 402, located at the top of the cyclone 4, for discharging the separated fibers. A liquid inlet 105 is provided at the top of the furnace wall of the disintegration furnace 1, communicating with the first outlet 401 of the cyclone 4. The separated depolymerized liquid flows back into the disintegration furnace 1 through this inlet 105 for reuse.

[0055] The cyclone 4 can efficiently separate the depolymerization liquid and the fibers, thereby improving the purity and efficiency of the separation. Through cyclone separation, the depolymerization liquid can be effectively recovered, waste can be reduced, and processing costs can be lowered. Cyclone separation reduces the generation of waste and helps to reduce the impact on the environment. The reflux of the depolymerization liquid helps to maintain the stability of the depolymerization liquid concentration in the disintegration furnace 1, thereby improving the stability and consistency of the treatment process. The separation effect of the cyclone 4 can be optimized by adjusting the operating parameters of the cyclone 4, thereby increasing the flexibility of the treatment process. By recycling the depolymerization liquid, the consumption of new depolymerization liquid can be reduced, thereby reducing operating costs. The efficient separation process helps to maintain the quality of the recovered fiber and improve its reuse value.
