In terms of weight, organic composite materials account for more than 90% of the weight of existing blades, and the rest is mainly glass fiber, etc. Wind turbine blade recycling generally adopts pyrolysis method, and pyrolysis recovery system is an important equipment in pyrolysis method.

[0016] A method for using a pyrolysis recovery system for glass fiber solid waste comprises the following steps: Step 1: The heating medium enters the furnace body through the air inlet pipe, and then enters the straight pipe from the high-pressure heating medium. The high-pressure heating medium pushes the conical sealing seat to move upward, and the conical sealing seat drives the straight sliding rod to move upward, and the straight sliding rod drives the movable block to move upward, and the movable block drives the blocking rod to move along the straight plate, and the outer end of the blocking rod moves into the hood body to open the air outlet. The heating medium enters the hood body through the gap between the conical sealing seat and the conical groove at the upper end, and then sprays out from the air outlet. The material is added to the feed pipe of the uniform feeding component, and the material falls to the rotating uniform distribution component through the feed pipe. The rotating uniform distribution component evenly distributes the material to the supporting circular plate of the sliding support component of the shaking component; Step 2: the second motor of the constant speed driving assembly rotates at a constant speed, the second motor drives the rotating shaft to rotate, the rotating shaft drives the third sprocket to rotate, the third sprocket drives the chain to rotate, the chain drives the first sprocket to rotate, the first sprocket drives the horizontal axis of the rotating pushing assembly to rotate, the horizontal axis drives the rotating plate to rotate, the rotating plate drives the rotating bearing to rotate, and when the rotating rotating bearing contacts with the supporting circular plate of the sliding support assembly, the supporting circular plate of the sliding support assembly is pushed to move upward, and when the rotating bearing of the rotating pushing assembly is separated from the supporting circular plate of the sliding support assembly, the supporting circular plate of the sliding support assembly moves downward by its own gravity under the action of the fixed seat and the sliding rod, so that the supporting circular plate of the sliding support assembly shakes up and down, so that the material on the supporting circular plate of the sliding support assembly shakes, and the heating medium is ejected from the air outlet and contacts with the material at the upper end of the supporting circular plate to perform pyrolysis treatment on the material; The first spring of the tensioning assembly in a compressed state drives the adjusting nut to move, the adjusting nut drives the screw to move, the screw drives the installation straight plate to move, the installation straight plate drives the second sprocket to move, the second sprocket tensions the chain connected to the third sprocket and the first sprocket, thereby ensuring stable driving of the constant speed driving assembly. When the constant speed driving assembly is stably driven, the rotating shaft of the metering sensing assembly calculates the torque of the second motor of the constant speed driving assembly. When the amount of material on the supporting circular plate is large, the driving requirement of the second motor is large, and the greater the torque of the second motor, the smaller the driving requirement of the second motor is when the amount of material on the supporting circular plate is small, and the smaller the torque of the second motor is. The remaining amount of material on the supporting circular plate of the sliding support assembly is calculated by torque, so that it is convenient to carry out material distribution in a timely manner. Step 3: During pyrolysis, the uniform distribution component drives the scraper to rotate along the inner wall of the furnace body, and the scraper can scrape off the coke adhered to the inner wall of the furnace body; Step 4: When the air inlet pipe stops entering the heating medium, the restoring force of the second spring drives the sliding seat to move downward, and the sliding seat drives the conical sealing seat to move downward.

The pyrolyzed material is discharged from the outlet pipe to the external cyclone dust collector. The tensioning component tensions the transmission component of the constant speed drive component to ensure the stable driving of the constant speed drive component. When the constant speed drive component is stably driven, the metering sensing component calculates the torque of the constant speed drive component, and calculates the remaining amount of material in the sliding support component through the torque, which is convenient for timely replenishment; when the air inlet pipe stops entering the heating medium, the anti-blocking wind hood is self-sealed to prevent the material from entering the anti-blocking wind hood, and the material in the air outlet can be pushed outward when blocking, so as to realize automatic clearing; during pyrolysis, the material-laying component rotates along the inner wall of the furnace body, and the coke adhered to the inner wall of the furnace body can be scraped off.

[0044] For example 2, please refer to Figure 1-Figure 10 , a method for using a pyrolysis recovery system for glass fiber solid waste, comprising the following steps: Step 1: The heating medium enters the furnace body 1 through the air inlet pipe 3, and then enters the straight pipe 86 from the high-pressure heating medium. The high-pressure heating medium pushes the conical sealing seat 85 to move upward, and the conical sealing seat 85 drives the straight sliding rod 812 to move upward. The straight sliding rod 812 drives the movable block 88 to move upward, and the movable block 88 drives the blocking rod 89 to move along the straight plate 810. The outer end of the blocking rod 89 moves into the hood body 81 to open the air outlet 82. The heating medium enters the hood body 81 through the gap between the conical sealing seat 85 and the conical groove 87 at the upper end, and then sprays out from the air outlet 82. The material is added to the feed pipe 42 of the uniformly spread feeding component 4, and the material falls to the rotating uniform distribution component through the feed pipe 42. The rotating uniform distribution component evenly distributes the material to the supporting circular plate 77 of the sliding support component of the shaking component 7; Step 2: The second motor 71 of the constant speed driving assembly rotates at a constant speed, the second motor 71 drives the rotating shaft 712 to rotate, the rotating shaft 712 drives the third sprocket 718 to rotate, the third sprocket 718 drives the chain 74 to rotate, the chain 74 drives the first sprocket 75 to rotate, the first sprocket 75 drives the horizontal shaft 76 of the rotating push assembly to rotate, the horizontal shaft 76 drives the rotating plate 711 to rotate, the rotating plate 711 drives the rotating bearing 710 to rotate, the rotating rotating bearing 710 and the supporting circular plate 77 of the sliding support assembly are rotated. When in contact, the support circular plate 77 of the sliding support assembly is pushed to move upward. When the rotating bearing 710 of the rotating push assembly is separated from the support circular plate 77 of the sliding support assembly, the support circular plate 77 of the sliding support assembly moves downward by its own gravity under the action of the fixed seat 78 and the slide rod 79, so that the support circular plate 77 of the sliding support assembly shakes up and down, and the material on the support circular plate 77 of the sliding support assembly shakes. The heating medium is ejected from the air outlet 82 and contacts the material at the upper end of the support circular plate 77 to perform pyrolysis treatment on the material. The first spring 717 of the tensioning assembly in a compressed state drives the adjusting nut 715 to move, the adjusting nut 715 drives the screw rod 716 to move, the screw rod 716 drives the installation straight plate 719 to move, the installation straight plate 719 drives the second sprocket 713 to move, the second sprocket 713 tensions the chain 74 connected to the third sprocket 718 and the first sprocket 75, thereby ensuring stable driving of the constant speed driving assembly. Under the condition of stable driving of the constant speed driving assembly, the rotating shaft 712 of the metering sensing assembly calculates the torque of the second motor 71 of the constant speed driving assembly. When the amount of material on the supporting circular plate 77 is large, the driving requirement of the second motor 71 is large, and the greater the torque of the second motor 71, the smaller the driving requirement of the second motor 71 when the amount of material on the supporting circular plate 77 is small, and the smaller the torque of the second motor 71, the remaining amount of material on the supporting circular plate 77 of the sliding supporting assembly is calculated by torque, so that it is convenient to carry out material laying in time; Step 3: During pyrolysis, the uniform distribution component is rotated to drive the scraper 48 to rotate along the inner wall of the furnace body 1, and the scraper 48 can scrape off the coke adhered to the inner wall of the furnace body 1; Step 4: When the air inlet pipe 3 stops entering the heating medium, the restoring force of the second spring 811 drives the sliding seat 83 to move downward, and the sliding seat 83 drives the conical sealing seat 85 to move downward. The conical sealing seat 85 moves downward until it is in contact with the conical groove 87 at the upper end to block the straight pipe 86. The sliding seat 83 drives the movable block 88 to move downward, and the movable block 88 drives the blocking rod 89 to move outward along the straight plate 810. The blocking rod 89 moves into the air outlet 82, and the outer end of the blocking rod 89 is located outside the outer end of the air outlet 82. The blocking rod 89 self-blocks the air outlet 82 to prevent the material from entering the anti-blocking wind hood 8, and when blocking, the blocking rod 89 moves to push the material in the air outlet 82 outward.
