Description

Technical Field

[0001] This disclosure pertains to the field of construction waste recycling, specifically relating to a construction waste recycling and processing equipment and process. Background Technology

[0002] As a common construction waste, glass fiber waste is naturally degraded through landfill, but the natural degradation rate is slow. Recycling long and short glass fibers can reduce environmental pollution and save energy and costs.

[0003] Long and short glass fibers are usually mixed together during recycling. However, they can be recycled and reused in different fields after different treatments based on their different characteristics. Long glass fibers, due to their longer fiber length, can be used to reinforce cement-based composite materials, improving their workability, mechanical properties, and durability. Short glass fibers, on the other hand, can be recycled through mechanical crushing and added as fillers or reinforcing materials to new composite materials, such as crack-resistant mortar. Therefore, it is necessary to recycle long and short glass fibers separately.

[0004] Before glass fibers are processed by pyrolysis or grinding, they need to be cleaned to remove surface impurities. For example, a washing device for recycling waste glass fibers with application number CN202211267785.X removes impurities by rinsing the glass fibers with clean water. However, short glass fibers are easily carried away by water during the rinsing process. If the size of the drain hole is reduced, long glass fibers can easily clog the drain. Furthermore, when cleaning the drain, one can easily be injured by the glass fibers, making it inconvenient to use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a construction waste recycling and processing equipment and process that solves the problems in existing technologies where short glass fibers are washed away by water during the rinsing process when long and short glass fibers are mixed and cleaned, resulting in the loss of raw materials, and where manual cleaning of the filter screen is prone to causing injury from glass fibers.

[0006] The objective of this disclosure can be achieved through the following technical solutions:

[0007] Construction waste recycling and processing equipment, including a support shell, winding assembly, and limiting assembly;

[0008] A cleaning component is fixed to the lower inner end face of the support shell, a driving component that penetrates the support shell is provided on the upper end face of the support shell, and a stirring cylinder is provided on the inner side of the support shell. Multiple rectangular holes are opened on the side wall of the stirring cylinder, and a cylindrical rod is fixed to the inner side of the rectangular holes.

[0009] The winding assembly is located inside the mixing drum, and the winding assembly includes a nut seat, a connecting rod and a lead screw. The lead screw is provided in the center of the inner side of the mixing drum, and the nut seat is spirally connected to the outer side of the lead screw. At least one rotating seat is fixed to the outer side of the nut seat, and the connecting rod is rotatably connected to the outer side of each of the multiple rotating seats.

[0010] A through groove is provided on the inner side of the connecting rod, and the inner wall of the through groove is tangent to the outer wall of the cylindrical rod.

[0011] Limiting components are provided on both sides of the connecting rod, and a filter plate is provided directly below the winding component. The side wall of the filter plate is provided with an upper discharge port that penetrates the support shell.

[0012] In some disclosures, the drive assembly includes a drive motor and a bearing, and the bearing is fixed to the upper outer wall of the stirring drum, and the upper end of the lead screw is connected to the output end of the drive motor.

[0013] In some disclosures, the cleaning assembly includes a spray head, a water tank, and a water pipe. The water tank is fixed to the upper end of the support shell, and a water pipe is connected through the upper end of the water tank. The end of the water pipe away from the water tank is connected to an external water source, and a spray head penetrating the support shell is provided at the lower end of the water tank.

[0014] In some disclosures, the limiting assembly includes a threaded rod, a gear, a limiting rod, and a convex thread. The threaded rod is provided through the inner side of the stirring cylinder, and a gear is fixed in the center of the threaded rod. Two limiting rods are symmetrically arranged at both ends of the threaded rod, and the inner sides of the two limiting rods are fixed with convex threads.

[0015] In some disclosures, racks are fixed on both sides of the nut seat, and the racks mesh with the gears.

[0016] In some disclosures, a ramp is provided directly below the filter plate, and a baffle is provided around the outside of the ramp, with a fiber cleaning pool located outside the baffle.

[0017] In some disclosures, a lower discharge port penetrating the support shell is provided on one side of the slope, and a water filter screen is provided on the inner side of the lower discharge port.

[0018] In some disclosures, a second cleaning brush is provided at the upper end of the lower discharge port, and a guide groove is fixed at the upper end of the second cleaning brush, and one side of the second cleaning brush is connected to a second electric telescopic rod.

[0019] In some disclosures, a first cleaning brush is provided on the upper surface of the filter plate, and the length of the first cleaning brush is greater than the diameter of the filter plate. A fixing block is fixed to one end of the first cleaning brush, and a first electric telescopic rod is fixed to one side of the fixing block.

[0020] A construction waste recycling and processing technology, using the aforementioned construction waste recycling and processing equipment, includes the following steps:

[0021] S1. Insert the glass fiber into the interior of the support shell from the top, start the drive motor, drive the lead screw to rotate, and drive the nut seat to move vertically downward through the thread on the outside of the lead screw.

[0022] S2. During the movement of the nut seat, the racks on both sides mesh with the gears, thereby driving the gears and threaded rods to rotate, causing multiple limit rods to retract inward until the racks pass through the gears;

[0023] S3. The lead screw continues to rotate until the nut seat moves to contact the bottom of the mixing drum. At this time, the nut seat is axially restricted by the mixing drum, so that the nut seat drives the mixing drum to rotate coaxially, and the glass fiber is wound around the outside of the mixing drum through multiple connecting rods.

[0024] S4. Simultaneously activate the cleaning component, spray the cleaning liquid in the water tank onto the glass fiber outside the mixing drum through the spray head, and clean the glass fiber of both length and length by adsorbing and rinsing the dust on the surface of the glass fiber through the cleaning liquid.

[0025] S5. The stirring drum is driven to rotate at high speed by the nut seat. The centrifugal force of the stirring drum during rotation is used to throw the short glass fibers and the cleaning liquid with dust adsorbed on the outside of the stirring drum outward.

[0026] S6. Short glass fibers and cleaning liquid pass through the filter plate and move to the top of the slope, and then move along the slope to the water filter screen. The second electric telescopic rod drives the second cleaning brush to flush the short glass fibers on the water filter screen into the fiber cleaning pool.

[0027] S7. After cleaning, the drive motor drives the lead screw to reverse, thereby causing the nut seat to move upward. Multiple connecting rods retract inward, and the rack drives the gear to rotate, causing multiple limit rods to extend outward. This prevents the long glass fiber from moving further when it reaches below the limit rod. After the connecting rod retracts into the mixing drum, the support below the long glass fiber disappears, causing the long glass fiber to fall onto the upper surface of the filter plate.

[0028] S8. Start the first electric telescopic rod. The first electric telescopic rod drives the first cleaning brush to slide along the upper surface of the filter plate and sweep the long glass fibers on the upper surface of the filter plate out from the upper discharge port, thereby completing the cleaning and sorting of the glass fibers.

[0029] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0030] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;

[0031] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0032] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.

[0033] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0034] The beneficial effects of this disclosure are:

[0035] 1. An winding device is installed inside the support shell. The centrifugal force of the winding assembly during rotation is used to throw off the fine dust and short fibers adsorbed on the fiber surface. The short glass fibers are then filtered twice through the filter plate to reduce the loss of short glass fibers, thereby separating and collecting long and short glass fibers.

[0036] 2. The winding assembly and the limiting assembly work together to reduce the upward support force of the connecting rod on the glass fiber after the connecting rod retracts inward. This causes the long glass fiber to fall directly above the filter plate under the influence of gravity, thereby automatically removing the long glass fiber from the winding assembly. This reduces the need for workers to clean the long fibers on the outside of the mixing drum by hand, which is beneficial to protecting the health of the workers. Attached Figure Description

[0046] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0047] Please refer to Figures 1 to 7 Construction waste recycling and processing equipment, including a support shell 1, a winding assembly and a limiting assembly;

[0048] A cleaning component is fixed to the lower inner surface of the support shell 1, and a driving component penetrating the support shell 1 is provided on the upper inner surface of the support shell 1. A stirring cylinder 2 is provided on the inner side of the support shell 1, and multiple rectangular holes 21 are opened on the side wall of the stirring cylinder 2. A cylindrical rod 211 is fixed inside the rectangular holes 21.

[0049] The winding assembly is located inside the mixing drum 2, and the winding assembly includes a nut seat 3, a connecting rod 4 and a lead screw 5. The lead screw 5 is provided in the center of the inner side of the mixing drum 2, and the nut seat 3 is spirally connected to the outer side of the lead screw 5. At least one rotating seat 31 is fixed to the outer side of the nut seat 3, and the connecting rod 4 is rotatably connected to the outer side of multiple rotating seats 31.

[0050] A through groove 41 is provided through the inner side of the connecting rod 4, and the inner wall of the through groove 41 is tangent to the outer wall of the cylindrical rod 211.

[0051] Limiting components are provided on both sides of the connecting rod 4, and a filter plate 7 is provided directly below the winding component. The side wall of the filter plate 7 is provided with an upper discharge port 101 that penetrates the support shell 1.

[0052] The drive assembly is activated, causing the lead screw 5 to rotate. The lead screw 5 is screwed into the nut seat 3 via a thread. Simultaneously, connecting rods 4 are rotatably connected to both ends of the nut seat 3. Because of the connection to the mixing drum 2, the circumferential resistance of the nut seat 3 increases during the rotation of the lead screw 5 due to the influence of the connecting rods 4. This causes the nut seat 3 to move vertically downwards along the lead screw 5. At the same time, the connecting rods 4 rotate around the rotating seat 31, causing the ends of the two connecting rods 4 furthest from the nut seat 3 to expand outwards. This increases the radius swept by the connecting rods 4 during rotation, which is beneficial for improving the coverage area of ​​the winding assembly. Furthermore, because the radius of the connecting rods 4 changes with the position of the nut seat 3, when the lead screw 5 reverses direction, the nut seat 3 moves vertically upwards along the lead screw 5. This causes the ends of the multiple connecting rods 4 furthest from the nut seat 3 to move inwards. Since the mixing drum 2 stops rotating during this process, the long glass fibers wound on the outside of the mixing drum 2 do not shrink inwards and tighten. The inward movement of the connecting rods 4... During the process, the glass fiber wrapped in a mesh structure on the outside will loosen. Because the surface of the mixing drum 2 is smooth, when the connecting rod 4 retracts inward to the end away from the nut seat 3 and fits against the cylindrical rod 211 inside the rectangular hole 21, the position of the long glass fiber is restricted by the limiting component. This helps to prevent a large number of fibers from entering the interior of the mixing drum 2 along the rectangular hole 21 when the connecting rod 4 retracts inward. Subsequently, the long glass fiber will fall down along the outer wall of the mixing drum 2 onto the filter plate 7, thereby automatically removing the long glass fiber from the outside of the winding component. Compared with manually removing the long glass fiber, this avoids hand injuries and improves the protection of workers.

[0053] When long and short glass fibers simultaneously enter the interior of the support shell 1, the long glass fibers are wound around the outside of the connecting rods 4 and the stirring drum 2 as the multiple connecting rods 4 rotate. When the nut seat 3 rotates to the end of the lead screw 5, the nut seat 3 can no longer make a downward linear movement as the lead screw 5 continues to rotate. At this time, the nut seat 3 is also restricted by the circumferential direction of the connecting rods 4, causing the nut seat 3 to drive the connecting rods 4 and the stirring drum 2 to rotate concentrically. During the rotation of the connecting rods 4, the long glass fibers are wound around the outside of the stirring drum 2. At the same time, the winding assembly rotates rapidly, and the centrifugal force of the winding assembly during rotation throws the short glass fibers off the outside of the stirring drum 2. At this time, the long glass fibers are wound around the upper end of the stirring drum 2, while the short glass fibers pass through the filter plate 7 and move to the fiber cleaning tank 12, thereby distinguishing between long and short glass fibers for separate storage and use. The upper end of the winding assembly is equipped with... The device is equipped with a cleaning component. During the process, the cleaning component sprays a large amount of cleaning fluid onto the winding component. The cleaning fluid comes into contact with and adsorbs dust on the long and short glass fibers. Meanwhile, the stirring drum 2, during its rotation, uses centrifugal force to fling out the cleaning fluid containing the dust. In some embodiments, the long and short glass fibers are cleaned by repeatedly rinsing them with a high-pressure water pump. However, in this method, because the short glass fibers are smaller and less likely to entangle with the long glass fibers, they are easily blown away along with dust and other impurities, resulting in the loss of short glass fibers and waste of glass fiber raw materials. After the coolant containing the dust dries, the dust can easily re-adsorb onto the glass fibers. Compared with the high-pressure water pump rinsing method, using the centrifugal force of the winding component during rotation to fling out the cleaning fluid containing impurities simultaneously improves the cleaning effect of the device.

[0054] The drive assembly includes a drive motor 6 and a bearing 61. The bearing 61 is fixed to the upper outer wall of the stirring drum 2, and the upper end of the lead screw 5 is connected to the output end of the drive motor 6. The output end of the drive motor 6 is coaxially arranged with the lead screw 5, so that when the drive motor 6 rotates, it can drive the lead screw 5 to rotate. At the same time, the outer wall of the bearing 61 is fixed to the support shell 1, and the inner wall of the bearing 61 is fixed to the outer wall of the stirring drum 2. The stirring drum 2 is fixed by the bearing 61, so that when the lead screw 5 drives the stirring drum 2 to rotate, the stirring drum 2 can cooperate with the rollers inside the bearing 61 and the stirring drum 2 can rotate relative to the support shell 1, which is convenient for cooperation with the winding assembly, and thus convenient for winding long glass fibers onto the outer wall of the stirring drum 2.

[0055] The cleaning assembly includes a spray head 9, a water tank 91, and a water pipe 92. The water tank 91 is fixed to the upper surface of the support shell 1, and the water pipe 92 is connected through the upper end of the water tank 91. The end of the water pipe 92 away from the water tank 91 is connected to an external water source, and the spray head 9 is installed at the lower end of the water tank 91, penetrating the support shell 1. By setting up the cleaning assembly, external cleaning liquid is drawn into the water tank 91 through the water pipe 92, and then the cleaning liquid in the water tank 91 is sprayed onto the mixing drum 2 through the spray head 9. The cleaning liquid then adsorbs the dust on the glass fiber, and then the cleaning liquid and dust are thrown off together by gravity and centrifugal force, which helps to improve the cleaning ability of the device.

[0056] The limiting assembly includes a threaded rod 8, a gear 81, a limiting rod 82, and a convex thread 83. The threaded rod 8 is provided through the inner side of the mixing cylinder 2, and the gear 81 is fixed in the center of the threaded rod 8. Two limiting rods 82 are symmetrically arranged at both ends of the threaded rod 8, and the inner side of each of the two limiting rods 82 is fixed with a convex thread 83. The threads on the threaded rod 8 are symmetrically distributed on both sides of the gear 81, and are left-handed and right-handed respectively. The threads on the threaded rod 8 are adapted to the convex threads 83 on the inner side of the mixing cylinder 2. The two limiting rods 82 are tightened with the threads on the threaded rod 8 through the convex threads 83 on their inner sides. When the nut seat 3 moves upward along the screw 5, racks 32 are fixed on both sides of the nut seat 3, and the racks 32 mesh with the gears 81. The racks 32 on both sides of the nut seat 3 mesh with the two gears 81 respectively, driving the two gears 81 to rotate simultaneously. At the same time, since the gears 81 are fixedly connected to the threaded rod 8, they can drive the two threaded rods 8 to rotate simultaneously. When the threaded rod 8 rotates, since the position of the threaded rod 8 is fixed, when it rotates, it can drive the two limiting rods 82 to move outward through the threads until the racks 32 completely pass through the inner side of the limiting assembly. At this time, the two ends of the limiting rods 82 pass through the inner wall of the mixing cylinder 2, and the limiting rods 82 are in... When the mixing drum 2 contracts inward, the long glass fibers on the outside of the mixing drum 2 are blocked by the limiting rod 82, reducing the possibility of the long glass fibers moving upward with the connecting rod 4 and passing through the rectangular hole 21 into the mixing drum 2. This reduces the possibility of the glass fibers getting stuck in the winding assembly. Before the winding assembly rotates again, when the nut seat 3 moves downward, the rack 32 and the gear 81 mesh again, thereby driving the gear 81 and the threaded rod 8 to rotate in opposite directions. This causes multiple limiting rods 82 to be tightened with the threaded rod 8 through the threads and contract to the inside of the mixing drum 2, allowing the long glass fibers to fall smoothly. The movement method of the limiting assembly being contracted by the lifting and lowering of the nut seat 3 helps to ensure that the long glass fibers are scraped off the outside of the mixing drum 2 in advance before each rotation of the mixing drum 2. This reduces the possibility of the winding assembly getting stuck due to excessive long glass fibers outside the mixing drum 2 caused by human error when the winding assembly is started without timely cleaning.

[0057] A ramp 10 is provided directly below the filter plate 7, and a baffle 11 is arranged around the outside of the ramp 10. The outer side of the baffle 11 is a fiber cleaning pool 12. The ramp 10 is a platform with a certain inclination angle. When the cleaning liquid and short glass fibers fall onto the ramp 10, the short glass fibers are washed from a higher position to a lower position of the ramp 10 by the cleaning liquid. This guides the movement path of the cleaning liquid and the short glass fibers. The baffle 11 further restricts the movement path of the cleaning liquid to prevent the cleaning liquid from flowing directly out from the edge of the ramp 10. This reduces the flow rate of the cleaning liquid above the ramp 10, making it easier for the short glass fibers to adhere to the upper surface of the ramp 10, thus requiring subsequent cleaning of the ramp 10.

[0058] A lower discharge port 102 penetrating the support shell 1 is provided on one side of the slope 10, and a filter screen 1021 is provided on the inner side of the lower discharge port 102. The cleaning liquid is filtered through the filter screen 1021, and a large number of short glass fibers are adsorbed on the filter screen 1021. Then, a second cleaning brush 14 is provided at the upper end of the lower discharge port 102, and a guide groove 141 is fixed at the upper end of the second cleaning brush 14. One side of the second cleaning brush 14 is connected to a second electric telescopic rod 142. The second electric telescopic rod 142 drives the second cleaning brush 14 to move back and forth along the side of the filter screen 1021 close to the slope 10, thereby pushing the short glass fibers on the surface of the filter screen 1021 into the fiber cleaning pool 12 from both sides of the filter screen 1021, thereby completing the classification of long glass fibers and short glass fibers. In this way, the short glass fibers on the cleaning filter screen 1021 can be moved and cleaned to reduce the risk of glass fibers pricking the hands of workers when cleaning by hand.

[0059] A first cleaning brush 13 is provided on the upper end face of the filter plate 7, and the length of the first cleaning brush 13 is greater than the diameter of the filter plate 7. A fixing block 131 is fixed to one end of the first cleaning brush 13, and a first electric telescopic rod 132 is fixed to one side of the fixing block 131.

[0060] The first electric telescopic rod 132 drives the first cleaning brush 13 to slide back and forth on the upper surface of the filter plate 7, thereby timely feeding long glass fibers into the upper discharge port 101 to avoid clogging the filter plate 7 with long glass fibers, and the long glass fibers are discharged from the upper discharge port 101 in advance to avoid mixing of long and short glass fibers again.

[0061] A construction waste recycling and processing technology, using the aforementioned construction waste recycling and processing equipment, includes the following steps:

[0062] S1. Insert the glass fiber into the interior of the support shell 1 from the upper end of the support shell 1, start the drive motor 6, drive the lead screw 5 to rotate, and drive the nut seat 3 to move vertically downward through the thread on the outside of the lead screw 5.

[0063] S2. During the movement of the nut seat 3, the racks 32 on both sides mesh with the gear 81, thereby driving the gear 81 and the threaded rod 8 to rotate, causing multiple limit rods 82 to retract inward until the racks 32 pass through the gear 81.

[0064] S3, the lead screw 5 continues to rotate until the nut seat 3 moves to contact the bottom of the mixing drum 2. At this time, the nut seat 3 is axially restricted by the mixing drum 2, so that the nut seat 3 drives the mixing drum 2 to rotate coaxially, and the glass fiber is wound around the outside of the mixing drum 2 through multiple connecting rods 4.

[0065] S4. Simultaneously activate the cleaning components, and spray the cleaning liquid in the water tank 91 onto the glass fiber outside the mixing drum 2 through the spray head 9. The cleaning liquid absorbs and washes the dust on the surface of the glass fiber, cleaning both long and short glass fibers at the same time.

[0066] S5. The stirring drum is driven to rotate at high speed by the nut seat 3. The centrifugal force of the stirring drum 2 during rotation is used to throw the short glass fibers and the cleaning liquid with dust adsorbed on the outside of the stirring drum 2 outward.

[0067] S6. Short glass fibers and cleaning liquid pass through the filter plate 7 and move to the top of the ramp 10, and move along the ramp 10 to the filter screen 1021. Then, the second electric telescopic rod 142 drives the second cleaning brush 14 to flush the short glass fibers on the filter screen 1021 into the fiber cleaning pool 12.

[0068] S7. After cleaning, the drive motor 6 drives the lead screw 5 to reverse, thereby causing the nut seat 3 to move upward. Multiple connecting rods 4 retract inward, and the rack 32 drives the gear 81 to rotate, thereby causing multiple limiting rods 82 to extend outward. When the long glass fiber moves to below the limiting rod 82, it cannot continue to move. After the connecting rods 4 retract into the mixing drum 2, the support below the long glass fiber disappears, causing the long glass fiber to fall onto the upper surface of the filter plate 7.

[0069] S8. Start the first electric telescopic rod 132. The first electric telescopic rod 132 drives the first cleaning brush 13 to slide along the upper end surface of the filter plate 7 and sweep the long glass fibers on the upper end surface of the filter plate 7 out from the upper discharge port 101, thereby completing the cleaning and sorting of the glass fibers.

6. The construction waste recycling and processing equipment according to claim 1, characterized in that, A ramp (10) is provided directly below the filter plate (7), and a baffle (11) is provided around the outside of the ramp (10), and a fiber cleaning pool (12) is located outside the baffle (11).

7. The construction waste recycling and processing equipment according to claim 6, characterized in that, The slope (10) is provided with a lower discharge port (102) that penetrates the support shell (1) on one side, and a water filter screen (1021) is provided on the inner side of the lower discharge port (102).

8. The construction waste recycling and processing equipment according to claim 7, characterized in that, The upper end of the lower discharge port (102) is provided with a second cleaning brush (14), and the upper end of the second cleaning brush (14) is fixed with a guide groove (141), and one side of the second cleaning brush (14) is connected to the second electric telescopic rod (142).

9. The construction waste recycling and processing equipment according to claim 6, characterized in that, The filter plate (7) is provided with a first cleaning brush (13) on its upper end surface, and the length of the first cleaning brush (13) is greater than the diameter of the filter plate (7). One end of the first cleaning brush (13) is fixed with a fixing block (131), and one side of the fixing block (131) is fixed with a first electric telescopic rod (132).

10. A construction waste recycling and processing technology, using the construction waste recycling and processing equipment according to any one of claims 1-9, characterized in that, Includes the following steps: S1. Insert the glass fiber into the interior of the support shell (1) from the upper end of the support shell (1), start the drive motor (6), drive the lead screw (5) to rotate, and drive the nut seat (3) to move vertically downward through the thread on the outside of the lead screw (5); S2. During the movement of the nut seat (3), the racks (32) on both sides mesh with the gear (81), thereby driving the gear (81) and the threaded rod (8) to rotate, causing multiple limit rods (82) to retract inward until the rack (32) passes through the gear (81). S3. The lead screw (5) continues to rotate until the nut seat (3) moves to contact the bottom of the mixing drum (2). At this time, the nut seat (3) is axially restricted by the mixing drum (2), so that the nut seat (3) drives the mixing drum (2) to rotate coaxially, and the glass fiber is wound around the outside of the mixing drum (2) through multiple connecting rods (4). S4. Simultaneously start the cleaning component and spray the cleaning liquid in the water tank (91) onto the glass fiber outside the mixing drum (2) through the spray head (9). The cleaning liquid absorbs and washes the dust on the surface of the glass fiber, and cleans the glass fiber of both length and length at the same time. S5. The stirring drum is driven to rotate at high speed by the nut seat (3). The centrifugal force of the stirring drum (2) during rotation is used to throw the short glass fiber and the cleaning liquid with dust adsorbed on the outside of the stirring drum (2) outward. S6. Short glass fibers and cleaning liquid pass through the filter plate (7) and move to the top of the ramp (10), and move along the ramp (10) to the filter screen (1021). Then, the second cleaning brush (14) is driven by the second electric telescopic rod (142) to flush the short glass fibers on the filter screen (1021) into the fiber cleaning pool (12). S7. After cleaning, the drive motor (6) drives the lead screw (5) to reverse, thereby driving the nut seat (3) to move upward, multiple connecting rods (4) to retract inward, and the rack (32) drives the gear (81) to rotate, thereby causing multiple limiting rods (82) to extend outward, so that when the long glass fiber moves to the bottom of the limiting rod (82), it cannot continue to move. After the connecting rod (4) retracts into the mixing drum (2), the support below the long glass fiber disappears, causing the long glass fiber to fall to the upper surface of the filter plate (7). S8. Start the first electric telescopic rod (132). The first electric telescopic rod (132) drives the first cleaning brush (13) to slide along the upper end surface of the filter plate (7) and sweep the long glass fibers on the upper end surface of the filter plate (7) out from the upper discharge port (101), thereby completing the cleaning and sorting of the glass fibers.
