Description

Technical Field

[0001] This invention belongs to the field of dust removal, specifically a dust removal device for regenerated and recycled fiber spinning. Background Technology

[0002] During the spinning process, fibers (such as cotton, wool, and chemical fibers) generate a large amount of short fibers, dust, and impurities due to mechanical actions such as opening, combing, and drafting. These substances are collectively referred to as "spinning dust." If they are not effectively treated, they will cause a series of serious problems.

[0003] Dust and lint can re-adhere to the yarn, causing uneven yarn thickness, reduced strength, increased fuzz, and appearance defects, ultimately affecting the quality of the fabric. Inhalable dust can damage workers' respiratory systems, and long-term exposure may lead to occupational diseases such as pneumoconiosis. Therefore, it is necessary to use professional dust removal equipment to remove particulate matter from the air.

[0004] In traditional dust removal processes, high-speed airflow is typically sprayed directly from the top of the filter bag during cleaning. This airflow shakes off particles from the outside of the filter bag. However, this method only produces a high-intensity cleaning effect at the top of the filter bag. By the time the airflow reaches the bottom, a large amount is consumed, making it difficult to clean the bottom filter bag and causing significant damage to the top filter bag. This not only damages the filter bag but also results in poor cleaning efficiency, affecting subsequent dust removal efficiency.

[0005] Therefore, the present invention provides a dust removal device for regenerated and recycled fiber spinning. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The dust removal equipment for regenerated and recycled fiber spinning of the present invention includes a dust removal box, an upper cover fixedly connected to the top of the dust removal box, an exhaust pipe fixedly connected to the rear end of the upper cover, a sealing cover fixedly connected to the top of the dust removal box, a plurality of fixing holes opened on the top surface of the sealing cover, through which dust removal filter bags are placed, a discharge valve fixedly connected to the bottom of the dust removal box, a plurality of cleaning cones adapted to the positions of the fixing holes are arranged inside the upper cover, a plurality of nozzles are installed on the outer side of the cleaning cones, a transmission pipe for controlling the lifting and lowering of the cleaning cones is connected to the top of the cleaning cones, an air pump for transmitting airflow to the transmission pipe is fixedly connected to the top of the upper cover, and an air inlet pipe is installed on the outer side of the dust removal box near the top; This setup not only achieves highly efficient air dust removal, but also ensures that particles cleaned from the outside of the filter bags are not re-adsorbed by nearby filter bags during the cleaning phase, reducing cleaning difficulty. Simultaneously, the uniform dust removal method of the cleaning cone ensures that the long, cylindrical filter bags are evenly impacted by a suitable amount of airflow from top to bottom. This ensures that particles fall off without causing severe damage to the top filter bags due to excessive airflow at the top, while the bottom filter bags remain uncleaned. This extends the equipment's lifespan and guarantees subsequent dust removal efficiency.

[0008] Preferably, the cleaning cone is an inverted quadrangular pyramid shape, and the outer edges of the cleaning cone are rounded. The multiple nozzles are divided into four groups, each group of nozzles is distributed on the inclined surface of the cleaning cone, and the output end of each group of nozzles is inclined upward. The cleaning cone and the transmission pipe are rotatably connected by a connecting shaft. There are four surfaces with the same degree of inclination at the bottom of the cleaning cone. When the multiple nozzles spray air, the cleaning cone rotates stably. At the same time, since the output end of the nozzle is inclined upward, it also provides a downward thrust to the cleaning cone while rotating. As the transmission pipe is slowly released, the cleaning cone rotates and moves downward. The outwardly sprayed air can act evenly and circularly on the entire dust collector filter bag, effectively removing particles on the outside of the dust collector filter bag. While not damaging the dust collector filter bag, it thoroughly cleans the particles and ensures the subsequent dust removal effect.

[0009] Preferably, the dust collector filter bag includes an inner mesh frame, a filter cloth bag, and an outer cover frame from the inside out. The filter cloth bag is cylindrical in shape, and its outer edge is designed with outwardly protruding folded fabric. The folded fabric consists of two triangular filter cloths. By setting the folded fabric around the filter cloth bag, the folded fabric communicates with the inside of the filter cloth bag. In the working state, the folded fabric is evenly wrapped around the outside of the filter cloth bag, resembling umbrella fabric wrapped around an umbrella frame. This shape not only effectively increases the filtration effect due to the overlapping parts, but also increases the filtration area due to the multiple folds. Furthermore, the triangular shape of the folded fabric ensures that the upper part of the outer side of the filter cloth bag has the thickest overlap after wrapping, resulting in the strongest filtration effect. This design ensures a uniform filtration effect for the entire filter bag. Since the suction force originates from the top of the dust collector filter bag, the strongest suction is applied to the upper half of the filter bag. The use of outward-folded fabric not only effectively enhances the filtration effect of the upper half but also gradually reduces the filtration effect at the bottom, aligning with the equipment's design philosophy. Furthermore, after removing the filter bag, a simple shake is all it takes to unfold all the outward-folded fabric, facilitating cleaning. When installing the filter bag, simply place the entire filter bag into the installed outer frame, then insert the inner mesh frame, and finally use the inner mesh frame to flatten the filter bag. Then, by rotating the entire inner mesh frame and filter bag in one direction from the top, multiple outward-folded fabric spirals will wrap around the outside of the filter bag and inner mesh frame. Alternatively, the filter bag can be pre-shaped on the outside of the inner mesh frame before being placed into the outer frame.

[0010] Preferably, a fixing ring is fixed to the top of the filter bag, a support ring is provided at the top of the outer cover frame, and a gear ring is fixed to the top of the inner mesh frame. A slot adapted to the fixing ring is opened between the outer cover frame and the gear ring. After the filter bag is placed, the fixing ring at the top is put into the slot of the support ring, and finally the gear ring is used to press the fixing ring down from above to ensure the stable placement of the filter bag.

[0011] Preferably, multiple winding drums are fixedly connected to the top surface of the inner part of the upper cover, and a winding motor is fixedly connected to the outer side of the winding drums. The outer side of the transmission pipe is connected to the winding end of the winding motor. The winding and unwinding of the transmission pipe is controlled by the rotation of the winding motor, thereby controlling the rising and falling process of the cleaning cone. This flexible winding and unwinding operation can facilitate the installation and disassembly of the dust collector filter bag, which is more convenient and flexible than a fixed airflow duct.

[0012] Preferably, the multiple take-up drums are interconnected by a series pipe. The top of each take-up drum is connected to the series pipe, which is connected to an air pump. The air pump generates airflow, which is transmitted to each take-up drum through the series pipe. The top of the transmission pipe is connected to the output end of the winding motor, and the output end of the winding motor is connected to the series pipe through the take-up drum, thereby completing the airflow transmission.

[0013] Preferably, the outer frame is composed of multiple vertically arranged wide plates and multiple binding inclined plates, and the bottom of the outer frame is a closed metal disc structure. The inner mesh frame is composed of multiple vertically arranged metal tubes, and the bottom of the inner mesh frame is also a closed metal disc structure. The supporting structures of the outer frame and the inner mesh frame are both flat, wide and smooth outer surfaces. However, the particles of fiber spinning are often in the form of fine filaments. Traditional fine metal wire structures are prone to fiber entanglement, leading to cleaning difficulties. By changing the structure, the equipment is made more suitable for dust removal work of fiber spinning. At the same time, the bottom of the entire dust filter bag is sealed and does not perform filtration work, so as to match the function of the cleaning cone that can only clean the sides.

[0014] Preferably, both the binding inclined plate and the vertical wide plate are made of flat metal material, and the binding inclined plate is set at an angle. The metal tube is a smooth round tube, and the slot of the gear ring is provided with multiple protrusions. The cleaning cone will clean both the upper and lower sides. After the cleaning cone moves to the bottom, it controls the entire inner mesh frame and filter bag to rotate in the direction of the outer folded cloth winding. This not only tightens the winding effect of the outer folded cloth, but also exposes the part that was originally blocked by the outer frame, while the part that was originally used for dust removal is blocked by the frame. Through this operation, the filter bag that was originally not used can be used, while the part that has been used for a long time is temporarily stopped. Because after long-term use, the mesh gap of the used part of the filter bag will be enlarged, while the unused part will be squeezed. By alternating use, the dust removal efficiency of the filter bag can be maintained for a long time, and the service life of the filter bag can also be improved.

[0015] Preferably, the upper cover has multiple vertically arranged electric telescopic rods fixed inside. A reduction motor is fixed to the bottom of each electric telescopic rod, and a drive gear is fixed to the output end of the reduction motor. The drive gear meshes with a gear ring. By extending the electric telescopic rod, the drive gear meshes with the outer side of the gear ring. The reduction motor controls the rotation of the drive gear, which in turn drives the entire inner mesh frame to rotate. At the same time, since the gear ring has multiple protrusions in its groove, the friction is increased. When the gear ring rotates, it drives the entire filter bag to rotate, thereby completing the position adjustment of the filter bag.

[0016] Preferably, a docking valve is fixed to the bottom of the cleaning cone, and through holes are provided at the bottom of the inner mesh frame and the bottom of the filter bag. A connecting valve is installed at the bottom of the outer cover frame. Multiple exhaust holes are provided on the inner walls of the binding inclined plate and the vertical wide plate. When the cleaning cone moves to the bottom of the dust collector filter bag, the cleaning cone maintains the downward process of the center of the cleaning cone by uniformly spraying airflow outward. The connecting valve at the bottom of the outer cover frame passes through the filter bag and the inner mesh frame. The docking valve at the bottom of the cleaning cone can be magnetically docked with the connecting valve, so that the airflow can be connected to the outer cover frame through the docking valve and a part of the airflow is transferred to the outer cover frame. This allows a small amount of airflow to be sprayed outward from the exhaust hole, so that the filter bag no longer adheres to the outer cover frame, but adheres to the inner mesh frame, which assists the rotation process of the filter bag.

[0017] The beneficial effects of this invention are as follows: 1. The regenerated fiber spinning dust removal equipment of the present invention, through the simultaneous operation of the cleaning cone and multiple devices, not only achieves a highly efficient air dust removal effect, but also ensures that the particles cleaned from the outside of the dust collector filter bags will not be re-adsorbed by nearby dust collector filter bags during the cleaning stage, thus reducing the cleaning difficulty. At the same time, the uniform dust removal method of the cleaning cone ensures that the long cylindrical dust collector filter bags are evenly impacted by an appropriate amount of airflow from top to bottom, ensuring that particles fall off while preventing the top filter bags from being severely damaged due to excessive airflow at the top and the bottom filter bags from being uncleaned. This improves the service life of the equipment and ensures the subsequent dust removal efficiency.

[0018] 2. The dust removal equipment for regenerated fiber spinning of the present invention has four surfaces with the same degree of inclination at the bottom of the cleaning cone. When multiple nozzles spray air, the cleaning cone rotates stably. At the same time, since the output end of the nozzle is inclined upward, it also provides a downward thrust to the cleaning cone while rotating. As the transmission pipe is slowly released, the cleaning cone rotates and moves downward. The air sprayed outward can act evenly and circularly on the entire dust collector filter bag, effectively removing particles on the outside of the dust collector filter bag. It thoroughly cleans the particles without damaging the dust collector filter bag, ensuring the subsequent dust removal effect. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 9 As shown in the embodiment of the present invention, a dust removal device for regenerated fiber spinning includes a dust removal box 1. The top of the dust removal box 1 is fixedly connected to an upper cover 2. An exhaust pipe is fixedly connected to the rear end of the upper cover 2. The top of the dust removal box 1 is fixedly connected to a sealing cover 6. Multiple fixing holes 11 are opened on the top surface of the sealing cover 6. A dust removal filter bag 7 is placed through the fixing holes 11. A discharge valve 5 is fixedly connected to the bottom of the dust removal box 1. Multiple cleaning cones 15 are provided inside the upper cover 2, which are adapted to the positions of the fixing holes 11. Multiple nozzles 20 are installed on the outside of the cleaning cones 15. A transmission pipe 10 for controlling the lifting and lowering of the cleaning cones 15 is connected to the top of the cleaning cones 15. An air pump 3 for transmitting airflow to the transmission pipe 10 is fixedly connected to the top of the upper cover 2. An air inlet pipe 4 is installed on the outside of the dust removal box 1 near the top. Air from the fiber spinning workshop is delivered to the air inlet duct 4 via an air supply device. The air inlet duct 4 is tangential to the dust collector 1, allowing the airflow entering the dust collector 1 to move spirally along the wall. Under centrifugal force, particles in the airflow slide along the wall and fall to the bottom of the dust collector 1 under gravity. The exhaust pipe at the rear end of the upper cover 2 is connected to a suction device. The suction force acts on the dust collector 1 through the dust filter bag 7, guiding the airflow to partially pass through the dust filter bag 7 during the spiral movement. The dust filter bag 7 can isolate the particles in the airflow on its outer side. Clean air can flow out from the top of the dust collector filter bag 7 and eventually be discharged outward from the exhaust pipe, thus completing the dust removal function. By setting up multiple identical dust removal devices and connecting them to the same suction and air supply devices, the air inlet pipe 4 and exhaust pipe of one of the devices are periodically closed to keep the device in a sealed state. At this time, all the cleaning cones 15 in the control device enter the cavity of the dust collector filter bag 7 from above, and at the same time, the air pump 3 is turned on to deliver high-pressure air to the transmission pipe 10 and the cleaning cones 15. The air will be sprayed outward from the nozzle 20 and follow the flow of air. As the cleaning cone 15 descends, it gradually cleans the dust collector filter bag 7. High-pressure air sprays the particles filtered on the outside of the filter bag 7 outwards, and then discharges them from the discharge valve 5 under gravity. When the cleaning cone 15 moves to the bottom of the filter bag 7, it is controlled to rise evenly to complete the secondary cleaning, ensuring thorough cleaning of the outer particles. After cleaning, the equipment can resume airflow dust removal, restoring the connection between the inlet pipe 4 and the exhaust pipe, and then processing other equipment in sequence. This setup not only achieves highly efficient air dust removal, but also... Meanwhile, during the cleaning phase, because the entire equipment is in a sealed state, it can be ensured that the particles cleaned from the outside of the dust collector filter bag 7 will not be re-adsorbed by the nearby dust collector filter bags 7, reducing the difficulty of cleaning. At the same time, the uniform dust removal method of the cleaning cone 15 ensures that the long cylindrical dust collector filter bag 7 can be evenly impacted by an appropriate amount of airflow from top to bottom. This ensures that while particles fall off, the top filter bag is not severely damaged due to excessive airflow at the top, while the bottom filter bag is not cleaned properly. This improves the service life of the equipment and ensures the subsequent dust removal efficiency.

[0024] The cleaning cone 15 is an inverted quadrangular pyramid shape, and the outer edges of the cleaning cone 15 are rounded. The multiple nozzles 20 are divided into four groups, and each group of nozzles 20 is distributed on the inclined surface of the cleaning cone 15. The output end of each group of nozzles 20 is inclined upward. The cleaning cone 15 and the transmission pipe 10 are rotatably connected by a connecting shaft 19. During operation, the bottom of the cleaning cone 15 has four surfaces with the same degree of inclination. When multiple nozzles 20 spray air, the cleaning cone 15 rotates stably. At the same time, since the output end of the nozzles 20 is tilted upward, it also provides a downward thrust to the cleaning cone 15 while rotating. As the transmission pipe 10 is slowly released, the cleaning cone 15 rotates and moves downward. The airflow sprayed outward can act evenly and circularly on the entire dust collector filter bag 7, effectively removing particles from the outside of the dust collector filter bag 7. Without damaging the dust collector filter bag 7, it thoroughly cleans the particles and ensures the subsequent dust removal effect.

[0025] The dust removal filter bag 7 includes an inner mesh frame 16, a filter bag 18, and an outer cover frame 17 from the inside out. The filter bag 18 is cylindrical in shape, and the outer edge of the filter bag 18 is designed with an outwardly protruding folded cloth 30, which is composed of two triangular filter cloths. During operation, an outer folded cloth 30 is placed around the filter bag 18. The outer folded cloth 30 is connected to the inside of the filter bag 18. In the working state, the outer folded cloth 30 is evenly wrapped around the outside of the filter bag 18, resembling umbrella fabric wrapped around an umbrella frame. This shape not only effectively increases the filtration effect due to the overlapping parts, but also increases the filtration area due to the multiple folds. Furthermore, the triangular shape of the outer folded cloth 30 ensures that the upper part of the outer side of the filter bag 18 has the thickest overlap after wrapping, resulting in the strongest filtration effect. This setup ensures a uniform filtration effect for the entire filter bag 18. Since the suction force originates from the top of the dust collector filter bag 7, the strongest suction force is found in the upper half of the filter bag 18. The outer folded cloth 30 not only effectively enhances the filtration efficiency, but also... The upper part of the filter bag is filtered, while the filtration effect at the bottom is reduced in a stepped manner, which conforms to the design concept of the equipment. After removing the filter bag 18, a simple shake is all it takes to unfold all the outer folds 30, making it easy to clean. When installing the filter bag 18, simply place the entire filter bag 18 into the installed outer frame 17, then place the inner mesh frame 16 inside, clamp the filter bag 18 between the outer frame 17 and the inner mesh frame 16, and use the inner mesh frame 16 to simply flatten the filter bag 18. Then, control the entire inner mesh frame 16 and filter bag 18 to rotate in one direction from the top, so that multiple outer folds 30 spirally wrap around the outside of the filter bag 18 and the inner mesh frame 16. Alternatively, the filter bag 18 can be shaped on the outside of the inner mesh frame 16 before being placed into the outer frame 17.

[0026] The top of the filter bag 18 is fixed with a fixing ring 27, the top of the outer cover frame 17 is provided with a support ring 26, the top of the inner mesh frame 16 is fixed with a gear ring 24, and a slot 28 adapted to the fixing ring 27 is opened between the outer cover frame 17 and the gear ring 24. During operation, after the filter bag 18 is placed, the top fixing ring 27 is inserted into the slot 28 of the support ring 26, and finally the gear ring 24 is used to press the fixing ring 27 down from above to ensure the stable placement of the filter bag 18.

[0027] Multiple take-up drums 8 are fixedly connected to the top surface of the upper cover 2. A winding motor is fixedly connected to the outside of the take-up drums 8. The outside of the transmission pipe 10 is connected to the winding end of the winding motor. During operation, the rotation of the winding motor controls the retraction and expansion of the transmission pipe 10, thereby controlling the rising and falling of the cleaning cone 15. This flexible retraction and expansion operation facilitates the installation and disassembly of the dust filter bag 7, which is more convenient and flexible than a fixed airflow duct.

[0028] The multiple take-up drums 8 are interconnected by a series pipe 9, the top end of the take-up drum 8 is connected to the series pipe 9, and the series pipe 9 is connected to the air pump 3. During operation, airflow is generated by air pump 3, and the airflow is transmitted to each take-up drum 8 through series pipe 9. The top of transmission pipe 10 is connected to the output end of winding motor, and the output end of winding motor is connected to series pipe 9 through take-up drum 8, thereby completing the airflow transmission work.

[0029] The outer frame 17 is composed of multiple vertically arranged vertical wide plates 23 and multiple binding inclined plates 29, and the bottom of the outer frame 17 is a closed metal disc structure. The inner mesh frame 16 is composed of multiple vertically arranged metal tubes 25, and the bottom of the inner mesh frame 16 is also a closed metal disc structure. During operation, the supporting structures of the outer frame 17 and the inner mesh frame 16 are both flat, wide and smooth outer surfaces. However, the particles of fiber spinning are often in the form of fine filaments. The traditional fine metal wire structure is prone to fiber entanglement, making cleaning difficult. By changing the structure, the equipment is made more suitable for dust removal work of fiber spinning. At the same time, the bottom of the entire dust filter bag 7 is sealed and does not perform filtration work. This is to match the function of the cleaning cone 15, which can only clean the sides.

[0030] Both the binding inclined plate 29 and the vertical wide plate 23 are made of flat metal material, and the binding inclined plate 29 is set at an angle. The metal tube 25 is a smooth round tube, and the slot 28 of the gear ring 24 is provided with multiple protrusions. During operation, the cleaning cone 15 cleans both the top and bottom sides. After the cleaning cone 15 moves to the bottom, the entire inner mesh frame 16 and filter bag 18 are rotated in the direction of the outer folded cloth 30. This not only tightens the wrapping effect of the outer folded cloth 30, but also exposes the part that was originally blocked by the outer frame 17. The part that was originally used for dust removal is blocked by the frame. Through this operation, the filter bag 18 that was not originally used can be used, while the part that has been used for a long time is temporarily stopped. This is because after long-term use, the mesh gap of the used part of the filter bag 18 will be enlarged, while the unused part will be squeezed. By alternating use, the dust removal efficiency of the filter bag 18 can be maintained for a long time, and the service life of the filter bag 18 can also be improved.

[0031] Multiple vertically arranged electric telescopic rods 12 are fixedly connected inside the upper cover 2. A reduction motor 13 is fixedly connected to the bottom of the electric telescopic rod 12. A drive gear 14 is fixedly connected to the output end of the reduction motor 13. The drive gear 14 meshes with the gear ring 24. During operation, the electric telescopic rod 12 extends to engage the drive gear 14 with the outer side of the gear ring 24. The drive gear 14 is rotated by the reduction motor 13, which in turn drives the entire inner mesh frame 16 to rotate. At the same time, since there are multiple protrusions in the slot 28 of the gear ring 24, the friction can be increased. When the gear ring 24 rotates, it will drive the entire filter bag 18 to rotate, thereby completing the position adjustment of the filter bag 18.

[0032] The bottom of the cleaning cone 15 is fixed with a docking valve 21. The bottom of the inner mesh frame 16 and the bottom of the filter bag 18 are both provided with through holes. The bottom of the outer cover frame 17 is equipped with a connecting valve 22. Multiple exhaust holes are provided on the inner walls of the binding inclined plate 29 and the vertical wide plate 23. During operation, when the cleaning cone 15 moves to the bottom of the dust filter bag 7, the cleaning cone 15 sprays air outward evenly, maintaining the downward process of the center of the cleaning cone 15. The connecting valve 22 at the bottom of the outer cover frame 17 passes through the filter bag 18 and the inner mesh frame 16. The docking valve 21 at the bottom of the cleaning cone 15 can magnetically dock with the connecting valve 22, so that the airflow can be connected to the outer cover frame 17 through the docking valve 21 and a part of the airflow is transferred to the outer cover frame 17. This allows a small amount of airflow to be sprayed out from the exhaust hole, so that the filter bag 18 no longer adheres to the outer cover frame 17, but adheres to the inner mesh frame 16, assisting the rotation process of the filter bag 18.

[0033] During operation, air from the fiber spinning workshop is delivered to the air inlet duct 4 via an air supply device. The air inlet duct 4 is tangential to the dust collector 1, allowing the airflow entering the dust collector 1 to move spirally along the wall. Under centrifugal force, particles in the airflow slide along the wall and fall to the bottom of the dust collector 1 under gravity. The exhaust pipe at the rear end of the upper cover 2 is connected to a suction device. The suction force acts on the dust collector 1 through the dust filter bag 7, guiding the airflow to partially pass through the dust filter bag 7 during the spiral movement. The dust filter bag 7 can isolate the particulate matter in the airflow. Clean air flows out from the top of the dust collector filter bag 7 and is eventually discharged outwards through the exhaust pipe, thus completing the dust removal function. By setting up multiple identical dust removal devices and connecting them to the same suction and air supply devices, the air inlet pipe 4 and exhaust pipe of one of the devices are periodically closed to keep the device in a sealed state. At this time, all cleaning cones 15 in the control device enter the cavity of the dust collector filter bag 7 from above, and at the same time, the air pump 3 is turned on to deliver high-pressure air to the transmission pipe 10 and the cleaning cones 15. The air will be sprayed outwards from the nozzle 20. As the cleaning cone 15 descends, it gradually cleans the dust collector filter bag 7. High-pressure air sprays the particles filtered on the outside of the dust collector filter bag 7 outwards, and then discharges them from the discharge valve 5 under gravity. When the cleaning cone 15 moves to the bottom of the dust collector filter bag 7, it is controlled to rise evenly to complete the secondary cleaning, ensuring that the outer particles are thoroughly cleaned. After cleaning, the equipment can resume airflow dust removal, restoring the connection between the air inlet pipe 4 and the exhaust pipe, and then processing other equipment in sequence. Through this setup, not only is a highly efficient air dust removal effect achieved, but also... Meanwhile, during the cleaning phase, because the entire equipment is in a sealed state, it can be ensured that the particles cleaned from the outside of the dust collector filter bag 7 will not be re-adsorbed by the nearby dust collector filter bags 7, reducing the difficulty of cleaning. At the same time, the uniform dust removal method of the cleaning cone 15 ensures that the long cylindrical dust collector filter bag 7 can be evenly impacted by an appropriate amount of airflow from top to bottom. This ensures that while particles fall off, the top filter bag is not severely damaged due to excessive airflow at the top, while the bottom filter bag is not cleaned properly. This improves the service life of the equipment and ensures the subsequent dust removal efficiency.

[0034] The bottom of the cleaning cone 15 has four surfaces with the same degree of inclination. When multiple nozzles 20 spray air, the cleaning cone 15 rotates stably. At the same time, since the output end of the nozzles 20 is tilted upward, it also provides a downward thrust to the cleaning cone 15 while rotating. As the transmission pipe 10 is slowly released, the cleaning cone 15 rotates and moves downward. The air sprayed outward can act evenly and circularly on the entire dust collector filter bag 7, effectively removing particles from the outside of the dust collector filter bag 7. Without damaging the dust collector filter bag 7, it thoroughly cleans the particles and ensures the subsequent dust removal effect.

[0035] By setting an outer folded cloth 30 around the filter bag 18, and having the outer folded cloth 30 connected to the inside of the filter bag 18, in the working state, the outer folded cloth 30 is evenly wrapped around the outside of the filter bag 18, resembling an umbrella cloth wrapped around an umbrella frame. This shape not only effectively increases the filtration effect due to the overlapping parts, but also increases the filtration area due to the multiple folds. Furthermore, the triangular shape of the outer folded cloth 30 ensures that the upper part of the outer side of the filter bag 18 has the thickest overlap after wrapping, resulting in the strongest filtration effect. This setup guarantees a uniform filtration effect for the entire filter bag 18. Since the suction force originates from the top of the dust collector filter bag 7, the strongest suction force is found in the upper half of the filter bag 18. The use of the outer folded cloth 30... This arrangement not only effectively enhances the filtration effect of the upper part but also gradually reduces the filtration effect of the bottom, conforming to the design concept of the equipment. After removing the filter bag 18, a simple shake is all it takes to unfold all the outer folds 30, facilitating cleaning and other operations. When installing the filter bag 18, simply place the entire filter bag 18 into the installed outer frame 17, then simply place the inner mesh frame 16 in, and finally use the inner mesh frame 16 to simply flatten the filter bag 18. Then, control the entire inner mesh frame 16 and filter bag 18 to rotate in one direction from the top, so that multiple outer folds 30 spirally wrap around the outside of the filter bag 18 and the inner mesh frame 16. Alternatively, the filter bag 18 can be shaped on the outside of the inner mesh frame 16 before being placed into the outer frame 17.

[0036] After the filter bag 18 is placed, the top fixing ring 27 is inserted into the slot 28 of the support ring 26, and finally the gear ring 24 is used to press the fixing ring 27 down from above to ensure the stable placement of the filter bag 18.

[0037] The rotation of the winding motor controls the retraction and expansion of the transmission tube 10, thereby controlling the rising and falling of the cleaning cone 15. This flexible retraction and expansion operation facilitates the installation and disassembly of the dust filter bag 7, which is more convenient and flexible than a fixed airflow duct.

[0038] Airflow is generated by air pump 3 and transmitted to each take-up drum 8 through series pipe 9. The top of transmission pipe 10 is connected to the output end of winding motor. The output end of winding motor is connected to series pipe 9 through take-up drum 8, thereby completing the airflow transmission.

[0039] The supporting structures of the outer frame 17 and the inner mesh frame 16 are both flat, wide and smooth outer surfaces. However, the particles of fiber spinning are often in the form of fine filaments. The traditional fine metal wire structure is prone to fiber entanglement, making cleaning difficult. By changing the structure, the equipment is made more suitable for dust removal work of fiber spinning. At the same time, the bottom of the entire dust filter bag 7 is sealed and does not perform filtration work. This is to match the function of the cleaning cone 15, which can only clean the sides.

[0040] The cleaning cone 15 cleans both the top and bottom sides. After the cleaning cone 15 moves to the bottom, it controls the entire inner mesh frame 16 and filter bag 18 to rotate in the winding direction of the outer folded cloth 30. This not only tightens the winding effect of the outer folded cloth 30, but also exposes the part that was originally blocked by the outer frame 17. The part that was originally used for dust removal is blocked by the frame. Through this operation, the filter bag 18 that was originally not used can be used, while the part that has been used for a long time is temporarily stopped. This is because after long-term use, the mesh gap of the part of the filter bag 18 will be enlarged, while the part that has not been used will be squeezed. By alternating use, the dust removal efficiency of the filter bag 18 can be maintained for a long time, and the service life of the filter bag 18 can also be improved.

[0041] The electric telescopic rod 12 extends to engage the drive gear 14 with the outer side of the gear ring 24. The drive gear 14 is rotated by the reduction motor 13, which in turn drives the entire inner mesh frame 16 to rotate. At the same time, since there are multiple protrusions in the slot 28 of the gear ring 24, the friction can be increased. When the gear ring 24 rotates, it will drive the entire filter bag 18 to rotate, thereby completing the position adjustment of the filter bag 18.

[0042] When the cleaning cone 15 moves to the bottom of the dust filter bag 7, the cleaning cone 15 sprays air outward evenly, maintaining the downward process of the center of the cleaning cone 15. The connecting valve 22 at the bottom of the outer cover frame 17 passes through the filter bag 18 and the inner mesh frame 16. The docking valve 21 at the bottom of the cleaning cone 15 can magnetically dock with the connecting valve 22, so that the airflow can be connected to the outer cover frame 17 through the docking valve 21 and a part of the airflow is transferred to the outer cover frame 17. This allows a small amount of airflow to be sprayed out from the exhaust hole, so that the filter bag 18 no longer adheres to the outer cover frame 17, but adheres to the inner mesh frame 16, assisting the rotation process of the filter bag 18.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
