Description

Technical Field

[0001] This invention relates to the field of carding machine technology, and more specifically, to a clean production device for recycling and reusing waste cotton from carding machines. Background Technology

[0002] In the textile industry, carding machines are key equipment for combing cotton fibers into a uniform cotton web. However, carding machines generate a large amount of waste filaments during operation. Directly discarding these waste filaments not only wastes resources but also increases production costs and environmental pollution control costs for enterprises. Currently, although some methods and devices exist for waste filament recycling, they generally suffer from low recycling efficiency, poor processing results, and difficulty in achieving clean production. For example, traditional recycling devices cannot effectively separate impurities from the waste filaments, resulting in poor quality recycled cotton fibers; and the recycling process easily generates dust, affecting the production environment and worker health. Therefore, a new type of clean production device needs to be designed to solve these problems. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a clean production device for recycling and reusing waste cotton from carding machines.

The feeding and dispersing component includes a collection tube and a stirring blade placed inside the collection tube. The stirring blade is driven to rotate by a rotary motor to disperse the waste filaments. The initial cleaning component is used to remove large particles and metal impurities from waste filaments. The initial cleaning component includes several filter plates, with the filter plate at the top having a larger pore diameter than the filter plate at the bottom. Magnetic sheets are adhered to the top surface of the filter plates to attract metal impurities. Collection bags, corresponding to each filter plate and symmetrically arranged on both sides of the collection tube, are fixedly connected to the side wall of the collection tube. Each filter plate has a push rod that slides along its surface, pushing the metal impurities and large particles on the surface of the filter plate into the collection bag. A wet dust removal component is used to clean small particulate impurities from waste filaments. The component includes a settling tank and a draining tank. A foaming agent is added to the settling tank to make dust float and waste filaments sink. Several connecting pipes are installed between the settling tank and the draining tank. One half of the connecting pipes is equipped with an electrically controlled one-way valve (I) connecting the settling tank to the draining tank, and the other half is equipped with an electrically controlled one-way valve (II) connecting the draining tank to the settling tank. Water is continuously added to the settling tank, causing dust to float and slide down. The connecting pipes open gradually, allowing liquid to flow from the settling tank into the draining tank. A pressure sensor is installed at the bottom of the draining tank. An electrically controlled sealing door is located at the bottom of the settling tank. When the liquid level in the settling tank exceeds half, the electrically controlled sealing door gradually opens. After the electrically controlled sealing door opens, the electrically controlled one-way valve (II) opens, allowing liquid in the draining tank to flow back into the settling tank to clean its inner wall. When the liquid level in the draining tank is less than half, the electrically controlled sealing door closes, but liquid continues to be discharged into the settling tank. A drying component is used to dry waste fibers after cleaning by a wet dust removal component. The drying component includes a water-spinning mesh bag and a shielding tube. The shielding tube is sleeved on the outside of the water-spinning mesh bag. The water-spinning mesh bag is detachably connected to a precipitation cylinder. The end of the water-spinning mesh bag away from the precipitation cylinder is fixed by a cable tie and detachably connected to the rotor of a motor. The shielding tube has a built-in heating device to dry the fibers inside the water-spinning mesh bag.

[0005] The present invention is further configured such that: the cross-sectional shape of the collecting tube is rectangular, the stirring blade is horizontally placed inside the collecting tube, and one end of the stirring blade protrudes from the side wall of the collecting tube, and the stirring blade is made of high-quality steel.

[0006] The invention is further configured such that: an air jet pipe is surrounding the connection between the collection bag and the collection tube, one end of the air jet pipe is connected to a small air pump, and several air outlets are provided on the side wall of the air jet pipe, with the air outlets of the air jet pipe surrounding the opening of the collection bag to prevent waste filaments from entering.

[0007] The present invention is further configured such that: a sliding groove is provided on the side wall of the collecting tube, a rubber sheet is fixedly connected to the inner wall of the sliding groove, a sliding plate is fixedly connected to one end of the pushing rod, the sliding plate passes through the sliding groove and its outer peripheral wall is in contact with the rubber sheet, a rack is fixedly connected to the sliding plate, and the racks on two adjacent pushing rods are connected by gear transmission, and any one of the gears is driven to rotate by a motor.

[0008] The present invention is further configured such that the bottom opening of the collecting tube faces the precipitation cylinder, and an ultrasonic oscillation device is provided inside the precipitation cylinder.

[0009] The present invention is further configured such that: the diameter of the drainage cylinder is smaller than the diameter of the precipitation cylinder, a PLC control center is provided at the precipitation cylinder, and the pressure sensor, electric sealing door, electrically controlled one-way valve one and electrically controlled one-way valve two are all electrically connected to the PLC control center.

[0010] The invention is further configured such that: a sealing buckle is provided at the other end of the water-spraying net bag; the motor controlling the water-spraying net bag is a servo reciprocating motor; a plurality of heat dissipation fins are fixedly connected to the inner wall of the shielding tube; a water guiding channel is formed between adjacent heat dissipation fins; the water-spraying net bag and the shielding tube are inclined as a whole; and a water tank is provided at the bottom of the shielding tube.

[0011] In summary, the present invention has the following beneficial effects: This device achieves efficient recycling and resource utilization of waste fibers through a multi-stage linkage design, significantly improving the level of clean production. First, the feeding and dispersing unit uses a spiral stirring head to powerfully disperse the waste fibers, effectively separating fibers from impurities. Simultaneously, a sprocket drive propels the primary cleaning unit, achieving coordinated operation. The primary cleaning unit uses multi-stage magnetic filter plates to adsorb metallic impurities, and a plastic pusher pushes large particles into the collection bag. Airflow from the jet pipe prevents waste fibers from entering the collection bag, further improving the fiber recovery rate. The wet dust removal unit uses a foaming agent and ultrasonic oscillation in synergy, causing dust to float with the foam and be discharged through overflow, achieving a dust removal efficiency of over 95%. Simultaneously, PLC intelligently controls the liquid exchange between the precipitation and drainage cylinders, achieving a self-cleaning function and reducing wastewater discharge. The drying unit combines centrifugal water removal and hot air drying for dual dehydration, reducing the moisture content of the waste fibers to below 5%. The inclined water guide channel and heat dissipation fins optimize drainage and drying efficiency. The entire system adopts a closed-loop water circulation and heat recovery design to reduce energy consumption and environmental pollution. The PLC system monitors the pressure, valves and motor actions in real time to ensure that all components operate in coordination, with a low failure rate and convenient maintenance. Ultimately, it achieves high recycling of waste filaments, low impurity residue and efficient reuse, greatly reducing raw material waste and improving production sustainability.

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] A clean production device for recycling and reusing waste cotton from carding machines, such as... Figures 1-6 As shown, the device includes a carding machine body, characterized in that: a waste filament recycling device 1 is connected to the carding machine body, the waste filament recycling device 1 includes a feeding and dispersing component, a preliminary cleaning component, a wet dust removal component and a drying component arranged sequentially from top to bottom, the waste filament is conveyed downward by gravity; the waste material cleaned by the carding machine is conveyed to the feeding and dispersing component by manual or mechanical means, the feeding and dispersing component is located at the top, and the waste material after preliminary dispersing is conveyed downward by gravity.

[0016] The feeding and dispersing component is used to collect the cleaned waste filaments. It includes a collection pipe 2 and stirring blades placed inside the collection pipe 2. The stirring blades are driven by a rotary motor to rotate and disperse the waste filaments. The collection pipe 2 has a rectangular cross-section, with the stirring blades horizontally positioned inside, one end of which protrudes from the side wall of the collection pipe 2. The stirring blades are made of high-quality steel. A funnel-shaped receiving part is welded to the top of the collection pipe 2, increasing its cross-sectional area and facilitating the feeding of waste materials. The stirring blades are spiral stirring heads. A motor driving the spiral stirring head is also mounted on the frame. A fixing rod is connected to the rotor of the motor, and the other end of the fixing rod is connected to the spiral stirring head. Next, a sprocket is welded onto the fixed rod, and a second sprocket 25 is provided on the primary cleaning component to cooperate with this sprocket. The first sprocket and the second sprocket 25 are driven by a chain 24. The second sprocket 25 is fixedly connected to one of the gears 19 on the primary cleaning component through a transmission rod. The motor drives the spiral stirring head to rotate, which disperses the waste material and drives the fixed rod and the first sprocket to rotate. The rotational force is transmitted to the second sprocket 25 through the chain 24. The second sprocket 25 drives any gear 19 in the primary cleaning part to rotate, thereby driving the primary cleaning part to operate and completing the entire pre-treatment stage of the waste material. The rotation of the stirring head separates the waste filaments and impurities in the waste material, which facilitates more thorough subsequent separation.

[0017] The initial cleaning component is used to remove large particles and metal impurities from the waste filaments. The initial cleaning component includes several filter plates 3. The filter holes of the upper filter plate 3 have a larger diameter than those of the lower filter plate 3. Magnetic sheets are attached to the top surface of the filter plate 3 to attract metal impurities. Collection bags 4 are fixedly connected to the side wall of the collection tube 2, corresponding to each filter plate 3 and symmetrically arranged on both sides of the collection tube 2. Each filter plate 3 is provided with a push rod 5 that slides along its surface. The push rod 5 pushes the metal impurities and large particles on the surface of the filter plate 3 into the collection bag 4.

[0018] The magnetic sheet on the filter plate 3 can be any common magnetic sheet that can attract metal. Some metal products that cannot be broken down can be attracted by the magnetic sheet and then pushed into the collection bag 4 by the push rod 5. The push rod 5 is preferably made of plastic to avoid the magnetic sheet attracting the push rod 5 and causing it to slide obstructed. The magnetic sheet is preferably glued and fixed to the filter plate 3. Over time, the magnetic attraction effect of the magnetic sheet will decrease and the friction of the push rod 5 will also cause wear of the magnetic sheet. The glued fixing method makes it easy to replace the magnetic sheet and ensures the removal effect of metal impurities. The magnetic sheet is provided with through holes that match the mesh holes of the filter plate 3. The multi-stage filtration method effectively removes large particulate impurities in the waste.

[0019] A sliding groove is provided on the side wall of the collection pipe 2. A rubber sheet 17 is fixedly connected to the inner wall of the sliding groove. A sliding plate is fixedly connected to one end of the push rod 5. The sliding plate passes through the sliding groove and fits against the rubber sheet 17 on its outer peripheral wall. A rack 18 is fixedly connected to the sliding plate. The racks 18 on two adjacent push rods 5 are connected by a gear 19. The motor that drives the stirring blade to rotate is a servo reciprocating motor. It rotates in the forward direction for a period of time and then in the reverse direction. The specific rotation time is adjusted according to the size of the equipment to ensure that the push rod 5 can slide to both ends of the filter plate 3. The number of filter plates 3 is also adjusted according to the size of the equipment. Each push rod 5 has a rack 18 that is fixedly connected to it. The motor drives the gear 19 to rotate and drive the rack 18 that meshes with the gear 19 to slide, thereby moving the push rod 5. The rack 18 located in the middle position is fixedly connected to the adjacent rack 18. The gear 19 drives the two racks 18 to slide in opposite directions, so the sliding directions of the adjacent push rods 5 are opposite, making the process of pushing and cleaning impurities on the filter plate 3 more efficient.

[0020] The cross-section of the sliding piece is set to a rhombus shape. The rhombus shape is designed to ensure that the connection area with the rack 18 is maximized while the distance between the two ends gradually decreases. This design allows for better contact with the deformed rubber sheet 17 when it passes through, preventing waste material from passing through the sliding groove and affecting the surrounding environment. It is also best to fix the rubber sheet 17 by adhesive. First, adhesive has good sealing performance. Second, adhesive makes it easy to replace the rubber sheet 17. Once the rubber sheet 17 ages, it can be replaced to ensure the stable achievement of its sealing effect.

[0021] A jet pipe 15 surrounds the connection between the collection bag 4 and the collection pipe 2. One end of the jet pipe 15 is connected to a small air pump 16. Several air outlets are provided on the side wall of the jet pipe 15. The air outlets of the jet pipe 15 surround the opening of the collection bag 4 to prevent waste filaments from entering. The small air pump 16 is connected to the side wall of the collection pipe 2. The air pump is selected according to actual needs. The small air pump 16 used here is required to be low power and lightweight so that it can be fixed on the side wall of the collection pipe 2. The gas delivered by the small air pump 16 is discharged from the air outlet along the jet pipe 15. The gas sprayed from the air outlet is sprayed at the opening of the collection bag 4. On the one hand, the air outlet can blow the surrounding waste filaments to float to the middle of the filter plate 3 and then fall down along the filter holes. On the other hand, the air outlet can prevent waste filaments from being pushed into the collection bag 4, thereby reducing the waste of waste filaments.

[0022] The wet scrubbing unit is used to remove small particulate impurities from waste fibers. It includes a settling tank 6 and a draining tank 7. A foaming agent is added to the settling tank 6 to make dust float and waste fibers sink. The foaming agent is a mixture of SDBS (0.2%) and AEO-9 (0.1%), with the pH adjusted to 8-9. Foam is generated through aeration, and dust floats with the foam. The waste fibers settle under the action of the flocculant, achieving a dust removal efficiency of over 95%. An overflow tank 20 is installed on the outside of the settling tank 6. After adding the foaming agent, the foam carries the dust to the surface. Liquid is then continuously added to the settling tank 6, and the floating foam flows out of the settling tank 6 with the liquid into the overflow tank 20. The overflow tank 20 is connected to a pipe to facilitate the discharge of the overflowing liquid, thus achieving the purpose of removing fine dust from the waste material.

[0023] Several connecting pipes 8 are installed between the precipitation cylinder 6 and the drainage cylinder 7. One half of the connecting pipes 8 is equipped with an electrically controlled one-way valve 9 connecting the precipitation cylinder 6 to the drainage cylinder 7, and the other half is equipped with an electrically controlled one-way valve 10 connecting the drainage cylinder 7 to the precipitation cylinder 6. As water is continuously added to the precipitation cylinder 6, dust floats up and slides off, gradually opening the connecting pipes 8 and allowing liquid to flow into the drainage cylinder 7. A pressure sensor 11 is installed at the bottom of the drainage cylinder 7. An electrically controlled sealing door 12 is installed at the bottom of the precipitation cylinder 6. When the liquid level in the precipitation cylinder 6 exceeds half capacity, the electrically controlled sealing door 12 gradually opens. After the electrically controlled sealing door 12 opens, the electrically controlled one-way valve 10 opens, allowing liquid in the drainage cylinder 7 to flow back into the precipitation cylinder 6 to clean the inner wall of the precipitation cylinder 6. When the liquid level is less than half full, the electric sealing door 12 closes but continues to discharge liquid into the precipitation cylinder 6. After the dust is discharged with the overflowing water, the electrically controlled check valve 9 opens, allowing the liquid in the precipitation cylinder 6 to flow into the drain cylinder 7. At this time, only the electrically controlled check valve is used. After opening, the liquid in the precipitation cylinder 6 can flow into the drain cylinder 7 as smoothly as possible. Several connecting pipes 8 are set at half the length of the precipitation cylinder 6. After multiple tests, the waste fibers left over when precipitating dust do not exceed half the length of the precipitation cylinder 6. Therefore, setting the connecting pipes 8 at half the length can ensure that the processed waste fibers sink to the bottom of the connecting pipes 8. At the same time, it can also discharge the wastewater from the precipitation cylinder 6 into the drain cylinder 7 as much as possible, reducing the subsequent drying time.

[0024] The bottom opening of the collection pipe 2 faces the precipitation cylinder 6. The precipitation cylinder 6 is equipped with an ultrasonic vibration device to better vibrate out fine dust from the waste. The diameter of the drainage cylinder 7 is smaller than that of the precipitation cylinder 6. A PLC control center 21 is installed at the precipitation cylinder 6. The pressure sensor 11, electric sealing door 12, electrically controlled one-way valve 9, and electrically controlled one-way valve 10 are all electrically connected to the PLC control center 21. As the liquid in the drainage cylinder 7 gradually increases, the pressure increases, and the pressure sensor 11 experiences increased pressure. The pressure sensor 11 will... The signal is released to the PLC control center 21, which drives the electric sealing door 12 to open. The electric sealing door 12 has two panels, both of which are slidably connected to the bottom surface of the precipitation cylinder 6. An electric cylinder is installed at the precipitation cylinder 6 to drive the electric sealing door 12 to slide. The top surface of the electric sealing door 12 is in contact with the bottom surface of the precipitation cylinder 6. When the electric sealing door 12 slides, the precipitation cylinder 6 can scrape off the waste fibers on the electric sealing door 12. The waste fibers on the electric sealing door 12 fall into the subsequent drying component.

[0025] When the liquid in the drain tank 7 exceeds the predetermined standard, the PLC control center 21 controls the one-way valve 1 to close and the one-way valve 2 to open, and the liquid in the drain tank 7 flows back into the precipitation tank 6, flushing the inner wall of the precipitation tank 6 and flushing the waste fibers on the inner wall of the precipitation tank 6 into the drying component. The inner wall of the precipitation tank 6 is equipped with a flushing pipe, which is connected to the connecting pipe 8 equipped with the one-way valve 2. The liquid flowing back from the drain tank 7 can wash the entire inner circumferential wall of the precipitation tank 6, ensuring the collection rate of waste fibers in the entire waste fiber recycling process. Although this process increases the difficulty of subsequent drying, it can recover as much waste fiber as possible.

[0026] When setting the control program for PLC control center 21, the following example can be used as a reference: Assume that the drainage cylinder 7 has a volume of 1m×1m×1m, and the precipitation cylinder 6 has a volume of 1.5 times that of the drainage cylinder 7. Set the pressure value sensed by pressure sensor 11 when the drainage cylinder 7 is fully loaded to 10000, then the pressure value when the precipitation cylinder 6 is fully loaded is 15000. When check valve one opens, the precipitation cylinder 6 drains water into the drainage cylinder 7, and the pressure value in the drainage cylinder 7 is greater than 8000N, PLC control center 21 controls the electric sealing plate to open. After the sealing plate is fully opened, PLC control center 21 controls check valve two to open and check valve one to close, flushing the perimeter of the precipitation cylinder 6. When the pressure value of pressure sensor 11 in the drainage cylinder 7 is less than 5000N, check valve two closes and the sealing plate closes.

[0027] The drying component is used to dry the waste fibers after cleaning by the wet dust collector. The drying component includes a water-spinning mesh bag 13 and a shielding tube 14. The shielding tube 14 is fitted over the outside of the water-spinning mesh bag 13. The water-spinning mesh bag 13 is detachably connected to the precipitation cylinder 6. The end of the water-spinning mesh bag 13 away from the precipitation cylinder 6 is fixed by a cable tie and detachably connected to the rotor of the motor. The shielding tube 14 has a built-in heating device to dry the fibers inside the water-spinning mesh bag 13. The other end of the water-spinning mesh bag 13 is equipped with a sealing buckle. The motor controlling the water-spinning mesh bag 13 is a servo reciprocating motor, and the recommended rotation speed is controlled between 600 and 1200 rpm. At 00 rpm, the motor drives the water-spinning net bag 13 to rotate, and the liquid in the water-spinning net bag 13 is thrown out under the action of centrifugal force to achieve the purpose of initial water-spinning and drying. The shielding tube 14 on the outside of the water-spinning net bag 13 can prevent the surrounding liquid from overflowing and affecting the surrounding working environment. For fine denier polyester yarn (monofilament fineness ≤ 1 denier), it is recommended that the mesh size of the water-spinning net bag 13 be 0.1~0.3mm, and for coarse denier polyester yarn (monofilament fineness > 1 denier), it is recommended that the mesh size of the water-spinning net bag 13 be 0.3~0.5mm. Select water-spinning net bags 13 with different mesh sizes according to different fibers to ensure water-spinning efficiency and waste yarn retention rate.

[0028] Several heat dissipation fins 22 are fixedly connected to the inner wall of the shielding tube 14, and water guiding channels are formed between adjacent heat dissipation fins 22. The water-spinning net bag 13 and the shielding tube 14 are inclined as a whole. A water tank 23 is provided at the bottom of the shielding tube 14. The heating device in the shielding tube 14 is a heating wire spirally arranged in the shielding tube 14. The residual liquid in the water-spinning net bag 13 is dried by high temperature. The water-spinning motor is a reciprocating motor. In order to ensure that the waste wire in the water-spinning net bag 13 is shaken more evenly and to speed up the drying efficiency, the length of the heat dissipation fins 22 is less than the difference between the maximum diameter of the water-spinning net bag 13 and the inner diameter of the shielding tube 14. The end of the heat dissipation fin 22 away from the shielding tube 14 is rounded. The heat dissipation fins 22 are made of aluminum-copper alloy, which has better thermal conductivity and can better transfer heat. Adjacent heat dissipation fins 22 can also form water guiding channels, so that the spun liquid slides down along the water guiding channels, which also speeds up the drainage and drying efficiency.

[0029] After drying, open the water-spinning net bag and pour out the waste fibers for recycling and reuse, reducing resource waste.
