Description

Technical Field

[0001] This invention relates to the field of waste wind turbine blade resource utilization technology, specifically to a device for separating different fibers in waste wind turbine blades. Background Technology

[0002] With the development of the wind power industry, the amount of retired wind turbine blades has surged. Among them, composite materials containing carbon fiber and glass fiber are not only lightweight but also high in strength, and are the most widely used in blade manufacturing. After these blades are scrapped, they usually undergo crushing, pyrolysis, and separation to recover usable resources such as gaseous products, pyrolysis oil, and fibers. In the separation process, a conveyor sends the mixed fibers into a flotation device. Utilizing the characteristics of carbon fiber's strong hydrophobicity and easy adsorption of air bubbles to float, and glass fiber's strong hydrophilicity and easy gravity settling, the two types of fibers are separated and recycled. At present, the mainstream fiber separation flotation equipment in the industry is mainly a separate process of coarse separation and fine purification, relying on independent feeding devices, sorting tanks, bubble generating devices, and collection mechanisms to complete the operation.

[0003] However, existing flotation equipment suffers from several technical drawbacks, making it difficult to meet the demands for efficient and high-value recycling: First, most existing equipment features a split layout, requiring a large footprint and making it unsuitable for site-constrained environments; second, the lack of a dispersion structure leads to fiber clumping, reducing dispersion efficiency and quality; third, bubbles are often injected from a single point on the top or side, resulting in uneven distribution and generally low purity of separated carbon fibers; fourth, existing equipment often uses scrapers to remove carbon fibers from the liquid surface, and mechanical friction can cause carbon fiber filament breakage and tensile strength loss, failing to meet the high-value requirements of recycled composite materials. Therefore, we propose a separation device for different fibers in waste wind turbine blades. Summary of the Invention

[0004] The purpose of this invention is to provide a separation device for different fibers in waste wind turbine blades, in order to solve the problems mentioned in the background art. These problems include: existing devices are mostly split-type layouts, occupying a large area and difficult to apply in space-constrained scenarios; lack of dispersion structure, resulting in easy fiber clumping, which reduces dispersion efficiency and quality; bubbles are mostly injected from the top or side single point, resulting in uneven distribution and generally low purity of carbon fiber separation; and the mechanical friction caused by scraping carbon fibers from the liquid surface with a scraper can lead to breakage of carbon fiber filaments and loss of tensile strength, making it difficult to meet the high-value requirements of recycled composite materials.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A device for separating different fibers from waste wind turbine blades includes: a mounting bracket, which includes a mounting platform. A fixed bracket is fixedly connected to the bottom surface of the mounting platform. A control cabinet is fixedly mounted on the front surface of the fixed bracket.

Inside the structure, a micro-nano bubble generator is installed on the top surface of the sorting mechanism away from the feeding mechanism. After the dispersing mechanism breaks up the mixed fibers, the propulsion mechanism pushes the broken mixed fibers from the middle of the liquid surface into the sorting liquid in the sorting mechanism. The carbon fiber component in the mixed fibers floats upward under the action of density difference, while the glass fiber component in the mixed fibers sinks downward under the action of density difference. The stirring mechanism drives the sorting liquid to rotate slowly without forming vortices on the liquid surface. The mixed fibers gain centrifugal force in the rotating sorting liquid and move towards the inner wall of the sorting mechanism. The micro-nano bubble generator sprays micro-nano bubbles from below the stirring mechanism. The carbon fibers are accelerated upward under the action of micro-nano bubbles.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention abandons the traditional separate structure of feeding trough, sorting trough, and collection trough. It highly integrates the core functional components of the feeding mechanism, separator, upper discharge mechanism, lower discharge mechanism fixed box, stirring mechanism, dispersing mechanism, propulsion mechanism, and micro-nano bubble generator into the sorting mechanism. This not only achieves better separation effect but also significantly reduces the footprint, making it flexible and adaptable to site-constrained scenarios such as factories and recycling stations. At the same time, after the mixed fibers enter through the collection hole, they are dispersed by the dispersing mechanism, propelled by the propulsion mechanism, stirred and separated by the stirring mechanism, and collected by the separator before being discharged by the upper discharge mechanism. The entire process flows inside the equipment without the need for external transfer, completely avoiding secondary fiber loss during the transfer process of separate equipment and improving the recovery rate.

[0016] This invention utilizes multiple dispersing rods arranged in a spiral trajectory on the surface of a dispersing tube, with the distribution density increasing from top to bottom. This allows for layered processing of fiber clumps, breaking down adhesions and combing them into fine fiber bundles. This avoids over-processing or incomplete processing. Combined with the propulsion mechanism's auger positioned across the liquid surface, it can smoothly press the dispersed fibers into the sorting liquid, preventing fiber aggregation on the liquid surface and ensuring that the fibers uniformly enter the subsequent separation stage, thereby improving the dispersion effect and subsequent separation efficiency.

[0017] This invention employs a linear distribution of multiple release heads on the bottom surface of the lower stirring assembly, with a denser arrangement closer to the distribution plate and a sparser arrangement further away. This ensures that micro- and nano-bubbles are densely distributed in the central region and sparsely distributed at the edges of the sorted liquid, specifically tailored to the separation needs of fibers in different areas. Simultaneously, the release heads move synchronously with the lower stirring assembly, breaking down the problem of bubble aggregation or gaps caused by fixed-point release. This allows for uniform bubble diffusion and maintains an effective morphology. Combined with the stable flow field created by the stirring mechanism, this facilitates efficient fiber separation under centrifugal force and bubble action, improving separation purity. The separator utilizes an overflow collection method to collect carbon fibers. During collection, the carbon fibers carried by the sorted liquid naturally slide down the surface of the gradient tube without mechanical scraper contact. Furthermore, the inclined structure of the upper discharge mechanism allows the carbon fibers to naturally slide into the collection box without mechanical friction damage, effectively preserving the original properties of the fibers to meet subsequent high-value utilization requirements.

Detailed Implementation

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] like Figures 1-12As shown, this application provides a device for separating different fibers in waste wind turbine blades, including: a mounting bracket 1, which includes a mounting platform 101, a fixed bracket 102 fixedly connected to the bottom surface of the mounting platform 101, a control cabinet 103 fixedly mounted on the front of the fixed bracket 102, a sorting mechanism 2 located in the middle of the mounting platform 101, the sorting mechanism 2 being filled with a sorting liquid, a feeding mechanism 3 at the top of the sorting mechanism 2, the feeding mechanism 3 being adapted to an external conveyor, the conveyor feeding mixed fibers into the feeding mechanism 3, the mixed fibers falling inside the feeding mechanism 3, a separator 4 inside the sorting mechanism 2, an upper discharge mechanism 5 on the right side of the sorting mechanism 2, a lower discharge mechanism 6 on the left side of the sorting mechanism 2, a fixed housing 7 on the feeding mechanism 3, and a stirring mechanism 8, a dispersing mechanism 9, and a propulsion mechanism 10 inside the fixed housing 7. The bottom of the structure 10 extends into the feeding mechanism 3 and the sorting mechanism 2. A micro-nano bubble generator 11 is provided on the top surface of the sorting mechanism 2 away from the feeding mechanism 3. After the dispersing mechanism 9 disperses the mixed fibers, the pushing mechanism 10 presses the dispersed mixed fibers from the middle of the liquid surface into the sorting liquid in the sorting mechanism 2. The carbon fiber component in the mixed fibers floats upward under the action of density difference, while the glass fiber component in the mixed fibers sinks downward under the action of density difference. The stirring mechanism 8 drives the sorting liquid to rotate slowly without forming a vortex on the liquid surface. The mixed fibers gain centrifugal force in the rotating sorting liquid and move towards the inner wall of the sorting mechanism 2. The micro-nano bubble generator 11 sprays micro-nano bubbles from below the stirring mechanism 8. The carbon fibers accelerate upward under the action of micro-nano bubbles. The separator 4 drives the sorting liquid to circulate internally and externally and pushes the carbon fibers to the upper discharge mechanism 5. The upper discharge mechanism 5 discharges the carbon fibers, and the lower discharge mechanism 6 discharges the glass fibers that have sunk to the bottom.

[0023] Please see Figure 5 The sorting mechanism 2 includes a sorting barrel 201, which is installed on the mounting platform 101. The sorting liquid is filled inside the sorting barrel 201. A carrying pipe 202 is sleeved on the top of the sorting barrel 201. An annular gap is formed between the top of the outer side of the sorting barrel 201 and the inner wall of the carrying pipe 202. A cover plate 203 is bolted to the top surface of the carrying pipe 202. The feeding mechanism 3, the fixed box 7, and the micro-nano bubble generator 11 are installed on the top surface of the cover plate 203. A supplementary pipe 204 is fixedly connected to the bottom of the sorting barrel 201 near the lower discharge mechanism 6. The supplementary pipe 204 is connected to an external sorting liquid supply device.

[0024] Please see Figure 3 , Figure 4 and Figure 5The feeding mechanism 3 includes a collecting hopper 301 and a collecting block 303. The collecting hopper 301 is bolted to the center of the bottom surface of the cover plate 203. The bottom end of the collecting hopper 301 is fixedly connected to a long neck tube 302. The bottom end of the long neck tube 302 extends into the sorting barrel 201 and is immersed in the sorting liquid. A round hole communicating with the collecting hopper 301 is opened on the cover plate 203. The collecting block 303 is fixedly installed on the top surface of the cover plate 203 away from the lower discharge mechanism 6. A collecting hole 304 is opened inside the collecting block 303. The collecting hole 304 communicates with the round hole. An inclined surface 305 is provided on the inner side of the collecting hole 304 away from the lower discharge mechanism 6. Both the collecting hole 304 and the inclined surface 305 are adapted to the round hole. The fixed box 7 is fixedly inserted into the side of the collecting block 303 near the lower discharge mechanism 6. The end of the fixed box 7 away from the lower discharge mechanism 6 is suspended above the round hole.

[0025] During feeding, the conveyor feeds the mixed fibers into the collection hole 304. Then, the mixed fibers slide down the inclined surface 305 under the action of gravity. Next, the mixed fibers pass through the round hole, the collection hopper 301, and the long neck tube 302 in sequence and enter the middle of the sorting liquid inside the sorting barrel 201. Then, the carbon fiber floats upward under the action of the density difference between it and the sorting liquid until it floats on the liquid surface, while the glass fiber sinks downward under the action of the density difference between it and the sorting liquid, thereby separating the carbon fiber and the glass fiber.

[0026] Please see Figure 10 and Figure 11 The dispersing mechanism 9 includes a dispersing motor 901, which is bolted to the side of the fixed housing 7 near the lower discharge mechanism 6. The output shaft of the dispersing motor 901 extends into the fixed housing 7 and is fixedly connected to a compensating rod. The other end of the compensating rod is fixedly sleeved with a second drive bevel gear 902. The lower part of the second drive bevel gear 902 meshes with a second transmission bevel gear 903. A dispersing tube 904 is fixedly inserted into the middle of the second transmission bevel gear 903. The dispersing tube 904 shares a central axis with the long neck tube 302. The bottom end of the dispersing tube 904 passes downward through the collecting hopper 301 and extends into the long neck tube 302. The bottom end of the dispersing tube 904 is suspended above the liquid surface. The dispersing tube 904 is fixed to the bottom surface of the fixed housing 7 by a bearing. Multiple dispersing rods 905 are fixedly connected to the surface of the dispersing tube 904. The multiple dispersing rods 905 are distributed on the surface of the dispersing tube 904 in a spiral trajectory and the distribution density increases from top to bottom.

[0027] During dispersion, the dispersion motor 901 rotates with the compensation rod, and then the compensation rod rotates with the second drive bevel gear 902. Next, the second drive bevel gear 902 rotates with the dispersion tube 904 through the meshing action between it and the second transmission bevel gear 903. Then, the dispersion tube 904 rotates with the dispersion rod 905. Finally, the rotating dispersion rod 905 disperses the mixed fibers before they fall into the sorting liquid, breaking up the mixed fibers and preventing the wet fibers from clumping and sinking when they directly contact the liquid surface.

[0028] By employing a spiral trajectory distribution and a design where the density increases sequentially from top to bottom, the 905 dispersing rod precisely adapts to the size variation of the mixed fiber clusters, effectively solving the problems of incomplete dispersion or excessive cutting and damage to fibers in traditional dispersing structures.

[0029] Please see Figure 10 and Figure 11 The propulsion mechanism 10 includes a propulsion motor 1001, which is bolted to the side of the fixed housing 7 near the lower discharge mechanism 6 and located above the dispersing motor 901.

The other end of the linkage rod is fixedly sleeved with a third drive bevel gear 1002. The lower part of the third drive bevel gear 1002 meshes with a third transmission bevel gear 1003. The middle part of the third transmission bevel gear 1003 is fixedly inserted with a propulsion tube 1004. The bottom end of the propulsion tube 1004 passes through the dispersing tube 904 and extends below it. The propulsion tube 1004 and the dispersing tube 904 are fixedly connected by a bearing. The outer surface of the propulsion tube 1004 is fixedly connected to a propulsion auger 1005 located below the dispersing tube 904. A small part of the top of the propulsion auger 1005 is above the liquid surface, and the rest is immersed in the sorting liquid.

[0030] When the mixed fibers are pushed into the sorting liquid, the propulsion motor 1001 drives the third drive bevel gear 1002 to rotate via the linkage rod. Then, the third drive bevel gear 1002 drives the propulsion tube 1004 to rotate through the meshing action between itself and the third transmission bevel gear 1003. Next, the propulsion tube 1004 drives the propulsion auger 1005 to rotate. Then, the propulsion auger 1005 pushes the mixed fibers and the sorting liquid inside the long neck tube 302 to move downward synchronously. Finally, the mixed fibers enter the sorting liquid inside the sorting barrel 201 from the bottom opening of the long neck tube 302.

The lower part of the first drive bevel gear 804 meshes with the first transmission bevel gear 805. A stirring shaft 806 is fixedly inserted into the middle of the first transmission bevel gear 805. The top end of the stirring shaft 806 extends from the top surface of the fixed housing 7. The stirring shaft 806 is fixed to the top surface of the fixed housing 7 by a bearing. The bottom end of the stirring shaft 806 passes sequentially through the propulsion tube 1004 and the long neck tube 302, extending into the sorting liquid inside the sorting tank 201. The stirring shaft 806 is fixed to the propulsion tube 1004 by a bearing. A straightening arm 813 is movably sleeved on the outside of the stirring shaft 806. Both ends of the straightening arm 813 are fixedly connected to the long neck tube 302. At the bottom of the inner side, a straightening arm 813 is used to straighten the stirring shaft 806. A splicing sleeve 807 is threaded onto the bottom of the stirring shaft 806. A transition cone ring 808 is fixedly connected to the top of the splicing sleeve 807. The transition cone ring 808 acts as a guide, separating the fibers in all directions. The transition cone ring 808 is fitted onto the outside of the stirring shaft 806. An upper stirring group 809 and a lower stirring group 810 are fixedly connected to the surface of the splicing sleeve 807. The upper stirring group 809 is located above the lower stirring group 810. The upper stirring group 809 includes five cylindrical rods evenly distributed around the perimeter of the splicing sleeve 807. The cylindrical rods are fixedly connected to the splicing sleeve 807. On the surface of the sleeve 807, the lower mixing group 810 includes five rectangular strips evenly distributed around the assembled sleeve 807. The rectangular strips are fixedly connected to the surface of the assembled sleeve 807. The first probe 811 and the second probe 812 are fixedly installed on the bottom surface of the cover plate 203 and distributed along the diameter of the cover plate 203. The first probe 811 is closer to the center of the cover plate 203. The first probe 811 and the second probe 812 are both connected to the control cabinet 103 for information transmission. Multiple grid plates 814 are fixedly connected at equal intervals to the inner wall of the sorting tank 201 and located below the lower mixing group 810. A channel is formed between two adjacent grid plates 814.

[0032] During agitation, control cabinet 103 controls the operation of variable frequency motor 801 and controls its speed. Then, variable frequency motor 801 drives stirring shaft 806 to rotate through the meshing action between transmission crossbar 802, first drive bevel gear 804 and first transmission bevel gear 805. Next, stirring shaft 806 drives upper stirring group 809 and lower stirring group 810 to rotate through assembly sleeve 807. Then, the sorting liquid inside sorting tank 201 rotates under the agitation of upper stirring group 809 and lower stirring group 810. Then, first probe 811 and second probe 812 monitor the liquid level in real time and send the information to control cabinet 103. Then, control cabinet 103 controls variable frequency motor 801 according to the liquid level difference. The rotational speed of the output shaft controls the liquid surface condition, thereby controlling the flow field to prevent significant eddies from forming on the liquid surface. This ensures that the fibers can accumulate on the inner wall of the sorting tank 201 under centrifugal force. Subsequently, the carbon fibers and glass fibers move synchronously in the sorting liquid. Then, under centrifugal force, the carbon fibers and glass fibers diffuse from the middle position of the sorting liquid to the edge position. At the same time, the carbon fibers move upward under buoyancy, and the glass fibers move downward under gravity. Then, the glass fibers enter the channel formed between adjacent grid plates 814. Since the grid plates 814 cut off the rotational inertia of the sorting liquid, the sorting liquid in the channel and below no longer rotates, allowing the glass fibers to settle more stably and faster.

[0033] Please see Figure 5 , Figure 11 and Figure 12 The micro / nano bubble generator 11 includes a main unit 1101, a distribution plate 1105, and a release head 1106. The main unit 1101 is fixedly mounted on the top surface of the cover plate 203. A suction pipe 1102 is connected to the lower right corner of the main unit 1101. The other end of the suction pipe 1102 is connected to the side of the sorting tank 201 near the lower discharge mechanism 6. A discharge pipe 1103 is connected to the top of the main unit 1101. The other end of the discharge pipe 1103 extends into the collection hole 304 and is fixedly connected to a rotary joint 1104. The rotary joint 1104 is fixedly connected to the top of the stirring shaft 806. The stirring shaft 806 is hollow. The inner cavity of 06 is connected to the rotary joint 1104. The diversion plate 1105 is fixedly connected to the bottom end of the assembly sleeve 807. The diversion plate 1105 is connected to the inner cavity of the stirring shaft 806. The lower stirring group 810 is fixedly connected to the side of the diversion plate 1105. The lower stirring group 810 is hollow. The inner cavity of the lower stirring group 810 is connected to the inner cavity of the diversion plate 1105. The release head 1106 is fixedly connected to the bottom surface of the lower stirring group 810. There are multiple release heads 1106. The multiple release heads 1106 are linearly distributed on the bottom surface of the lower stirring group 810. The closer they are to the diversion plate 1105, the denser they are. The farther away they are from the diversion plate 1105, the sparser they are.

[0034] Multiple release heads 1106 are linearly distributed on the bottom surface of the lower stirring group 810, with a denser arrangement closer to the distribution plate 1105 and a sparser arrangement further away from the distribution plate 1105. This arrangement ensures that there are more micro-nano bubbles near the propulsion auger 1005 than near the inner wall of the sorting tank 201, which can specifically improve the carbon fiber adsorption efficiency. This allows the carbon fibers that have just entered the liquid to quickly come into contact with the dense bubbles. The bubbles quickly coat the surface of the fibers, reducing their effective density and accelerating the transition from initial suspension to stable floating. This avoids the temporary sinking of carbon fibers due to insufficient bubbles and initial mixing with glass fibers, resulting in better separation.

[0035] When micro-nano bubbles are generated, the main unit 1101 draws in external air and extracts the sorted liquid through the suction pipe 1102. Then, the main unit 1101 pressurizes the air into the sorted liquid. Next, the main unit 1101 controls the sorted liquid to pass through the discharge pipe 1103, the rotary joint 1104, the internal cavity of the stirring shaft 806, the internal cavity of the distribution plate 1105, and the internal cavity of the lower stirring group 810, and is released from the release head 1106 in the form of micro-nano bubbles. The release head 1106 moves in a circular motion while releasing the liquid. Then, the micro-nano bubbles combine with the carbon fiber, and then the carbon fiber accelerates upward.

[0036] By setting the release head 1106 to release in a circular motion, the problem of local aggregation or gaps in the fixed-point release of bubbles can be broken, allowing micro- and nano-bubbles to diffuse evenly along a circular trajectory. On the other hand, the circular motion is consistent with the direction of the stirring flow field, which can reduce the relative friction between the bubbles and the liquid and prevent the micro- and nano-bubbles from agglomerating due to the impact of the counterflow. At the same time, in the sparse bubble area at the edge, the circular motion of the release head 1106 can make the sparse bubbles evenly distributed along the cylinder wall, which can accurately capture the small amount of carbon fiber moving towards the edge with the flow field, and prevent the glass fiber from being disturbed by the aggregation of bubbles, resulting in better separation effect.

[0037] Please see Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10The separator 4 includes a separation barrel 401, which is sleeved outside the sorting barrel 201 and the two share a central axis. The bottom end of the sorting barrel 201 is fixedly connected to the bottom surface of the inner cavity of the separation barrel 401, and the top end of the sorting barrel 201 is higher than the top end of the separation barrel 401. An annular cavity 402 is formed between the outer surface of the sorting barrel 201 and the inner wall of the separation barrel 401. The annular cavity 402 receives the overflowing sorting liquid. The suction pipe 1102 is connected to the annular cavity 402. A gradient tube 403 is abutted against the top of the separation barrel 401. The top end of the gradient tube 403 is slidably sleeved at the top end of the side of the sorting barrel 201. The top surface of the gradient tube 403 is flush with the top surface of the sorting barrel 201, and the edge of the bottom surface of the gradient tube 403 is flush with the outer surface of the separation barrel 401. Multiple separation holes 404 are opened on the gradient tube 403. The gradient tubes 403 are staggered, and the bottom surface of the gradient tubes 403 is fixedly connected to the positioning protrusions 405. The positioning protrusions 405 are inserted into the separation tank 401. The side of the separation tank 401 away from the lower discharge mechanism 6 is fixedly connected to the lead tube 406 located at its top. The lead tube 406 is used to run wires. The inner wall of the separation tank 401 away from the lower discharge mechanism 6 is fixedly installed with the monitoring integration 407. The monitoring integration 407 is connected to the control cabinet 103 for information transmission. The bottom surface of the inner cavity of the annular cavity 402 is bolted with a submersible pump 408. The submersible pump 408 is electrically connected to the control cabinet 103. The top of the submersible pump 408 is connected to the circulation pipe 409. The circulation pipe 409 passes through the gradient tubes 403 and is connected to the side of the long neck tube 302 away from the lower discharge mechanism 6. The end of the circulation pipe 409 points to the bottom of the dispersion tube 904.

[0038] The monitoring and integration unit 407 provides real-time feedback on the liquid level of the annular cavity 402 to the control cabinet 103. When the liquid level is too low, the control cabinet 103 controls the external sorting liquid supply equipment to supply liquid to the annular cavity 402 in order to control the liquid level inside the annular cavity 402 and replenish the lost sorting liquid.

[0039] During the sorting liquid circulation, the control cabinet 103 drives the submersible pump 408 to run. The submersible pump 408 then draws the sorting liquid from the annular cavity 402 and injects it into the long neck tube 302 through the circulation pipe 409. Then, under the combined action of gravity and the pressure applied by the propulsion auger 1005, the sorting liquid flows downward, pushing the mixed fibers into the sorting barrel 201. After that, the liquid level inside the sorting barrel 201 rises and overflows from the top of the sorting barrel 201 to the top surface of the gradient tube 403. At the same time, the overflowing sorting liquid pushes the carbon fibers at the edge of the liquid surface to the top surface of the gradient tube 403. Then, the carbon fibers are intercepted on the surface of the gradient tube 403. The sorting liquid flows back into the annular cavity 402 through the separation hole 404. Then, the carbon fibers intercepted on the top surface of the gradient tube 403 push the previously intercepted carbon fibers down the surface of the gradient tube 403. There are no mechanical parts such as scrapers in contact throughout the process, which avoids carbon fiber breakage.

[0040] Please see Figure 5The upper discharge mechanism 5 includes a collection cylinder 501, which is fixedly inserted into the installation platform 101. The bottom end of the collection cylinder 501 is inclined and connected to a discharge flat tube 502. The end of the discharge flat tube 502 away from the lower discharge mechanism 6 is lower than the end of the discharge flat tube 502 near the lower discharge mechanism 6. The end of the discharge flat tube 502 away from the lower discharge mechanism 6 is open and a collection box is provided below it. A support ring 503 is fixedly sleeved on the outside of the collection cylinder 501. The support ring 503 is bolted to the top surface of the installation platform 101.

[0041] When discharging carbon fibers, the carbon fibers that slide off the surface of the gradient tube 403 pass through the inner cavity of the collecting cylinder 501 and fall on the bottom surface of the inner cavity of the discharge flat tube 502. Then, under the action of gravity, the carbon fibers slide out along the bottom surface of the inner cavity of the discharge flat tube 502 and fall into the collecting box below the end of the discharge flat tube 502.

[0042] Please see Figure 4 and Figure 5 The lower discharge mechanism 6 includes a guide pipe 601, which is fixedly connected to the bottom of the sorting barrel 201. The bottom of the guide pipe 601 is inclined away from the upper discharge mechanism 5. A vertical long pipe 602 is fixedly connected to the bottom of the guide pipe 601. A bend pipe 603 is fixedly connected to the top of the vertical long pipe 602. A vertical short pipe 604 is fixedly connected to the other end of the bend pipe 603. A deflection pipe 605 is fixedly connected to the bottom of the vertical short pipe 604. A storage box is provided below the other end of the deflection pipe 605. A servo motor 606 is bolted to the bottom of the vertical long pipe 602. The servo motor 606 is electrically connected to the control cabinet 103. The output axis of the servo motor 606 extends upward into the interior of the vertical long pipe 602 and is fixedly connected to a shaftless auger 607.

[0043] When discharging glass fiber, the glass fiber is deposited inside the feed tube 601 and enters the vertical long tube 602. Then, the servo motor 606 rotates the shaftless auger 607 under the control of the control cabinet 103. The shaftless auger 607 then pushes the glass fiber upward. After that, the glass fiber leaves the liquid surface and enters the bend tube 603. Then, the glass fiber falls into the collection box through the vertical short tube 604 and the deflection tube 605.
