Description

Technical Field

[0001] This invention relates to the field of textile processing technology, and in particular to a fiber lint collection device for use in spinning workshops. Background Technology

[0002] During textile production, especially in processes such as carding, drawing, and spinning, a large amount of fiber lint is generated and suspended in the air. This lint not only pollutes the workshop environment and adheres to machinery, accelerating wear, but also affects workers' respiratory health and even poses a dust explosion hazard. Therefore, the cleaning and treatment of fiber lint in spinning workshops is crucial.

[0003] Currently, centralized negative pressure dust removal systems are commonly used in textile workshops. These systems typically consist of a high-power fan, a main duct, and branch ducts extending to each workstation. However, this traditional structure has significant drawbacks: due to the complex duct routing and the difficulty in perfectly balancing the resistance of each branch duct, there is a significant difference in negative pressure suction between the near and far ends. That is, the suction at workstations closer to the fan is too strong, even sucking up normal fibers, while the suction at workstations farther away is weak. This results in a large number of blind spots within the independent space of the workstation where the suction port is located. In these blind spots, the suction power is insufficient to completely capture the flying fibers, causing a large amount of flying fibers to disperse within the workstation area, affecting the environment, personnel, and equipment safety.

[0010] A further improvement is that the cyclone separation assembly includes a cyclone separation cylinder, with a tangential air inlet and a slag discharge nozzle at the upper end of the cyclone separation cylinder, and a slag discharge nozzle at the lower end of the cyclone separation cylinder. The slag discharge nozzle is connected to a branch connecting pipe, and the tangential air inlet is connected to a conveying pipeline. The tangential air inlet is located on the side of the cyclone separation cylinder and is tangential to the cyclone separation cylinder. A guide vane is fixedly installed on the inner side of the cyclone separation cylinder, and the guide vane extends towards the slag discharge nozzle.

[0011] A further improvement is that the partitioned lint-absorbing component includes an isolation chamber, the top of which is equipped with a bellows-style connecting pipe.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] according to Figure 1 , 2 As shown in 3, 4, 5, 6, and 7, this embodiment proposes a fiber lint collection device for a spinning workshop, including a main dust collection device 1 and multiple partitioned lint collection components 3. Each partitioned lint collection component 3 is connected to the main dust collection device 1 through a conveying pipeline 2. Before the system is started, the multi-group lint-collecting components 3 are arranged in the areas where lint-producing equipment such as spinning machines, carding machines, and drawing frames are located. They are connected to the main dust collection device 1 section by section through the conveying pipeline 2 to form a negative pressure pipeline network for zoned collection and centralized treatment. When the collection system is working, the fiber lint generated at each workstation is first captured in real time by the zoned lint-collecting components 3, and then transported to the main dust collection device 1 under negative pressure for separation, filtration and collection, so as to prevent the lint from being scattered in the workshop environment.

[0030] The combined approach of zoned collection and centralized collection can cover all lint-producing points in the spinning workshop, preventing the spread and accumulation of lint. This ensures both the cleanliness of the workshop and prevents lint from entangled in equipment and affecting production safety.

[0031] Each partitioned lint-absorbing component 3 is equipped with a supplementary air pressure stabilizing device 4, which is connected to the partitioned lint-absorbing component 3 to accelerate the gas flow in the partitioned lint-absorbing component 3 and balance the air pressure in the partitioned lint-absorbing component 3. When the negative pressure inside the partitioned lint suction component 3 is too high or too low, the air supply and pressure stabilization device 4 will automatically start to supply clean air into the isolation chamber 31 and accelerate the internal airflow circulation speed. Through real-time air supply adjustment, the air pressure in the lint suction hood 32 area is kept stable and the suction is stable and uniform, avoiding pipe blockage due to excessive negative pressure or incomplete lint removal due to insufficient negative pressure, thus improving the efficiency of lint transport.

[0032] Specifically, the total dust collection device 1 includes a first frame 11 and a plurality of second frames 12; The inner side of the first frame 11 is provided with a filter box assembly 13, a conical guide shroud 15 and a storage box assembly 16, and the outer side of the conical guide shroud 15 is provided with multiple branch connecting pipes 10. The inner side of the second frame 12 is provided with multiple cyclone separation components 17, each of which corresponds to a branch connecting pipe 10. The output end of the cyclone separation component 17 is connected to the conical guide shroud 15 through the branch connecting pipe 10, and the input end of the cyclone separation component 17 is connected to the partitioned lint suction component 3 through the conveying pipeline 2.

[0033] The conical guide shroud 15 is fixedly installed between the filter box assembly 13 and the storage box assembly 16, and the bottom of the filter box assembly 13 is connected to the top of the storage box assembly 16 through the conical guide shroud 15.

[0034] The airflow containing fiber fluff enters the cyclone separator assembly 17 through the delivery pipe 2, forming a high-speed vortex inside. Most of the fiber fluff is thrown against the cylinder wall and settles downwards under the action of centrifugal force, while the clean airflow rises through the separation nozzle 175 and enters the branch connecting pipe 10, achieving preliminary and efficient separation of air and fluff. The clean airflow after cyclone separation and the residual fine fibers enter the conical guide hood 15, and under the guidance of the conical structure, it flows upwards into the filter box assembly 13 for fine filtration. The separated fiber fluff falls downwards into the collection box assembly 16 under the action of gravity and the guiding force. Multiple branch connecting pipes 10 unify the airflow from multiple cyclone separator assemblies 17 into the conical guide hood 15, achieving convergence and pressure stabilization.

[0035] The conical air guide shroud 15 combines converging, guiding, and buffering functions, preventing interference between multiple airflow paths and achieving initial gravity separation of fibers and airflow, thus reducing the load on subsequent filtration. Employing multiple cyclones in parallel processing, it can quickly remove most coarse and long fibers, handling large air volumes with high separation efficiency, effectively reducing the risk of subsequent filtration clogging, and is suitable for high-concentration lint conditions in spinning workshops.

[0036] The main dust collection device 1 adopts a frame structure design. The first frame 11 is used to install the core components for filtering, guiding and storing. Multiple second frames 12 are distributed around the outside of the first frame 11, and a corresponding number of cyclone separation components 17 are installed respectively to form a multi-channel parallel separation structure, which can simultaneously process the flocculated airflow transported by multiple conveying pipelines 2 and improve the overall processing capacity.

[0037] Regarding filter assembly 13: The filter box assembly 13 includes a filter box body 131. The filter box body 131 is provided with a coarse filter mesh 132, a medium filter mesh 133 and a fine filter mesh 134 on its inner side. The coarse filter mesh 132, the medium filter mesh 133 and the fine filter mesh 134 are fixedly arranged on the inner side of the filter box body 131, and the medium filter mesh 133 is placed between the coarse filter mesh 132 and the fine filter mesh 134.

[0038] The coarse filter mesh 132, medium filter mesh 133, and fine filter mesh 134 are all equipped with gaps that allow airflow to pass through, with each gap decreasing in size from bottom to top. Airflow passes through the coarse filter mesh 132, medium filter mesh 133, and fine filter mesh 134 sequentially from bottom to top. The coarse filter mesh 132 intercepts larger clumps, the medium filter mesh 133 filters medium-sized fibers, and the fine filter mesh 134 captures fine fiber dust. This three-stage filtration process ensures that the exhaust gas meets the clean emission requirements of the workshop, guaranteeing filtration effectiveness while delaying filter clogging, extending the replacement and cleaning cycle, and reducing maintenance costs.

[0039] It is worth explaining in detail that a negative pressure fan 14 is provided on the top of the filter box assembly 13. The negative pressure fan 14 includes a fan cover 141, which is fixedly installed on the upper end of the filter box 131. Negative pressure blades 144 are provided on the inner side of the fan cover 141, and an air inlet 142 and an air outlet 143 are provided on the outer side of the fan cover 141. The negative pressure blades 144 are placed between the air inlet 142 and the air outlet 143. The air inlet 142 passes through the filter box 131 and communicates with the space above the fine filter mesh 134.

[0040] When the negative pressure fan 14 is powered on, the negative pressure blades 144 rotate at high speed to form a continuous negative pressure, which draws clean air from the filter box 13 upward through the air inlet 142 and then discharges it to the outside of the workshop or for recycling through the air outlet 143. The negative pressure fan 14 provides suction for the entire system, driving the flying lint from the partitioned lint suction component 3 to the main dust collection device 1. Therefore, it is necessary to ensure that the power is strong enough.

[0041] It should be noted that the filter housing 131 adopts a sealed design to prevent the filtered clean airflow from mixing with the unfiltered flocculated airflow, thus ensuring the filtration effect. The three-stage mesh of coarse filter, medium filter and fine filter can be designed to be detachable and washable, so as to be disassembled and cleaned regularly and reused, thereby reducing the cost of filter consumables.

[0042] Regarding storage box set 16: The storage box assembly 16 includes a dust collection box 161. The outer side of the dust collection box 161 is provided with a pull-out groove, which is connected to the inner cavity of the dust collection box 161. A pull-out box 162 is provided in the pull-out groove, which is placed below the conical guide shroud 15 and slidably connected to the pull-out groove.

[0043] After separation and filtration, the loose fibers fall into the pull-out box 162 under gravity for centralized storage. When the fibers accumulate to a certain amount in the pull-out box 162, they can be directly pulled out from the pull-out slot for emptying and cleaning. After cleaning, the box can be pushed back into its original position for continued use. The pull-out storage structure ensures centralized fiber collection and convenient cleaning without the need to stop the machine or disassemble complex parts, thus avoiding secondary dust generation.

[0044] Regarding Cyclone Separator Component 17: The cyclone separator assembly 17 includes a cyclone separator cylinder 171. The upper end of the cyclone separator cylinder 171 is provided with a tangential air inlet 174 and a slag discharge nozzle 175. The lower end of the cyclone separator cylinder 171 is provided with a slag discharge nozzle 172. The slag discharge nozzle 175 is connected to the branch connecting pipe 10. The tangential air inlet 174 is connected to the conveying pipe 2. The tangential air inlet 174 is located on the side of the cyclone separator cylinder 171 and is tangential to the cyclone separator cylinder 171. A guide vane 173 is fixedly provided on the inner side of the cyclone separator cylinder 171. The guide vane 173 extends towards the slag discharge nozzle 172.

[0045] The fibrous airflow enters tangentially along the inner wall of the cyclone separator 171 through the tangential air inlet 174. Guided by the guide vanes 173, it forms a stable vortex. Heavier particles gather towards the cylinder wall and slide down to the slag discharge nozzle 172 under centrifugal force, while the clean airflow carrying light lint flows upward and out through the lint discharge nozzle 175. The tangential air inlet combined with the guide vanes ensures stable vortex flow and higher centrifugal separation efficiency, effectively removing coarse and heavy impurity fibers and reducing the pressure on subsequent filtration.

[0046] A flow rate sensing unit can be installed inside the cyclone separator 17. By measuring the swirling velocity inside the cyclone separator 17, the flow rate can be dynamically adjusted according to the flocculation concentration. When the flocculation concentration is high, the swirling velocity is increased to improve the separation efficiency, and when the flocculation concentration is low, the velocity is reduced to save energy.

[0047] Regarding the partitioned lint-absorbing component 3: The partitioned lint suction component 3 includes an isolation chamber 31. The top of the isolation chamber 31 is provided with a bellows-style connecting pipe 34. One end of the bellows-style connecting pipe 34 is connected to the conveying pipeline 2, and the other end of the isolation chamber 31 is connected to the lint suction hood 32 located inside the isolation chamber 31. The lint suction hood 32 is fixedly connected to the bellows-style connecting pipe 34. Multiple air exchange ports 33 are provided on the outside of the isolation chamber 31, and each air exchange port 33 is arranged around the lint suction hood 32.

[0048] The lint-collecting hood 32 is close to the lint-generating area of ​​the equipment. Under negative pressure, it draws the flying lint into the isolation chamber 31 and then sends it into the conveying pipeline 2 through the bellows-type connecting pipe 34. The bellows-type connecting pipe 34 is telescopic and adjustable to adapt to different equipment heights and installation positions, and flexibly adjusts the lint-collecting position.

[0049] It should be noted that the isolation chamber 31 can be made of transparent material so that operators can observe the internal lint collection situation and detect blockage problems in time. The lint collection hood 32 adopts a trumpet-shaped design to increase the lint collection area and reduce the escape of flying lint. The air exchange vents 33 are evenly distributed to ensure uniform air supply and avoid local airflow turbulence from affecting the lint collection effect.

[0050] Regarding the air supply and pressure stabilizing device 4: The air supply and pressure stabilization device 4 includes an air box 41. An air supply branch pipe 42 is provided on the outside of the air box 41. The air supply branch pipe 42 is connected to each air exchange port 33 through the delivery pipeline 2. The air supply branch pipe 42 is connected to the fan mounting cavity 44 located inside the air box 41. An air supply fan 43 is provided inside the fan mounting cavity 44. An air supply dustproof net 45 is installed at the air inlet of the fan mounting cavity 44.

[0051] When the make-up air fan 43 starts, outside air enters the air box 41 after being filtered by the make-up air dustproof net 45, and is then sent into the isolation chamber 31 through the make-up air branch pipe 42 and the air exchanger 33, with the internal air pressure and flow rate being adjusted in real time. The make-up air dustproof net 45 prevents outside dust from entering the system, protecting the fan and pipelines. The make-up air branch pipe 42 can be flexibly arranged according to the number of zoned lint suction components 3 to ensure uniform make-up air volume at each air exchanger 33.

[0052] It is worth explaining in detail that a wind speed sensor 36 is provided on the top of the isolation chamber 31, and the sensing end of the air pressure sensor 35 extends into the isolation chamber 31. An air pressure sensor 35 is provided on the outside of the lint-absorbing cover 32, and the sensing end of the air pressure sensor 35 extends into the lint-absorbing cover 32.

[0053] The air pressure sensor 35 monitors the air pressure inside the suction hood 32 and the isolation chamber 31 in real time, and the airflow speed is monitored by the wind speed sensor 36. The monitoring data is transmitted to the control system. In conjunction with the corresponding control system, the data information is displayed on the operation panel in real time. The operator can intuitively view the operating parameters of each station. When an abnormality occurs, the system will automatically alarm to remind the operator to deal with it in time. At the same time, the control system can record the operating data to provide data support for later equipment maintenance and parameter optimization.

[0054] In a preferred embodiment, a sliding guide rail 164 is laid on the inner side of the dust collection box 161, and sliders are fixedly installed on the left and right sides of the pull-out box 162. The sliders are slidably connected to the sliding guide rail 164, and a pull handle 163 is provided on the outer side of the pull-out box 162 for easy pulling of the pull-out box 162.

[0055] The pull-out box 162 slides smoothly along the sliding guide rail 164 via a slider, ensuring a smooth pulling process. When pulling out, the lifting handle 163 allows for easy manual gripping, facilitating subsequent fiber cleaning and improving maintenance convenience.

[0056] In a preferred embodiment, a conical guide shroud 176 is provided above the guide vane 173. The conical guide shroud 176 is fixedly installed at the lower end of the separation nozzle 175 and separates the separation nozzle 175 from the tangential air inlet 174. The lower end of the conical guide shroud 176 has a gap between it and the inner wall of the cyclone separator 171 to allow airflow to pass through.

[0057] The conical guide shroud 176 prevents the newly entered fibrous airflow from escaping directly upwards, forcing the airflow to swirl downwards along the cylinder wall, thus improving the centrifugal separation effect. Simultaneously, it guides the light, fibrous airflow smoothly upwards into the separation nozzle 175, avoiding swirling disturbances, improving cyclone separation efficiency, reducing fiber escape, and enhancing the overall collection effect. Specifically, the conical guide shroud 176 can be made of lightweight, corrosion-resistant materials, without affecting the overall weight and swirling effect of the cyclone separator 171. Polishing its surface further reduces fiber clump adhesion.

[0058] It is worth explaining in detail that the inner side of the second frame 12 is provided with multiple slag discharge cylinders 18, and the slag discharge cylinders 18 are threadedly connected to the lower port of the slag discharge nozzle 172.

[0059] The long, coarse fibers separated by the cyclone separator fall through the discharge nozzle 172 into the discharge cylinder 18 for centralized storage. The discharge cylinder 18 can be quickly disassembled via threads, allowing for periodic removal and emptying of the internal fiber waste. The threaded connection enables quick assembly and disassembly, centralized collection of waste, prevents fiber scattering, and keeps the bottom of the equipment clean.

[0060] To ensure the stable and safe operation of the equipment, a comprehensive inspection must be conducted before and after startup, and regular inspections and maintenance must be performed. The specific procedures are detailed below: I. Preparations before startup 1. Arrange the partitioned lint suction components 3 next to each lint-generating device, adjust the lint suction hood 32 to align with the lint-generating point, and check that there are no leaks in the isolation chamber 31.

[0061] 2. Connect all pipes, check that the joints are sealed and leak-free, and ensure that the make-up air branch pipe 42 is securely connected.

[0062] 3. Check the status of each core component to confirm that there are no abnormalities in the filter box assembly 13, cyclone separator 17, and make-up air pressure stabilizing device 4, and that the sensors and control system are working properly.

[0063] 4. By pre-setting key parameters such as air pressure and speed in the control system, it can be adapted to the workshop conditions.

[0064] II. Startup and Operation 1. Connect the main power supply and confirm that the power supply to the control system and each component is normal.

[0065] 2. Start the negative pressure fan 14 and confirm that it is operating normally and forming a stable negative pressure.

[0066] 3. Activate the air supply and pressure stabilization device 4 and adjust the air pressure synchronously to ensure stable suction force.

[0067] 4. Closed-loop system operation: The lint-collecting hood 32 captures flying lint and transports it through pipelines to the cyclone separator 17 for pre-separation. Coarse fibers fall into the slag discharge cylinder 18. The initially clean airflow flows through the conical guide hood 15 and into the filter box group 13 for fine filtration. Clean air is discharged, and fine fibers fall into the collection box group 16. Sensors monitor in real time, and the system automatically adjusts operating parameters.

[0068] III. Routine Inspection and Maintenance 1. Conduct regular inspections to ensure that the parameters on the control panel are normal and that the equipment operates without abnormal noise or vibration.

[0069] 2. Check the pipeline for leaks and blockages, and address any abnormalities promptly.

[0070] 3. Observe the fiber accumulation in the slag discharge cylinder 18 and the pull-out box 162, and arrange cleaning as appropriate.

[0071] 4. Check the cleanliness of the air supply dustproof net 45 and the filter screen of the filter box assembly 13, and clean or record them in a timely manner.

[0072] 5. Confirm that the accordion-style connecting pipe 34 is undamaged and adjust its position as needed.

[0073] IV. Maintenance and Cleaning 1. Periodically unscrew the slag discharge cylinder 18, clean the internal fibers, and then reinstall it.

[0074] 2. Pull out the 162 cleaning box to remove fibers, then push it back into place to avoid secondary dust generation.

[0075] 3. Regularly stop the machine to disassemble and clean the three-stage mesh of filter box 13, and replace it in time when it is damaged or aged.

[0076] 4. Clean all components regularly, and inspect and maintain guide vanes, sensors, etc., to ensure that the equipment is in normal working order.

[0077] 5. If a blockage is found in the pipeline, stop the machine, clear the blockage, and then reconnect and seal it.

[0078] V. Shutdown Operation 1. First, shut down the fluff-generating equipment. After no new fluff is generated, turn off the air supply and pressure stabilization device 4.

[0079] 2. After waiting a moment, turn off the negative pressure fan 14 to ensure that the remaining fluff in the pipeline is completely transported out.

[0080] 3. Clean the residual fibers and dust from the slag discharge cylinder 18 and the pull-out box 162.

[0081] 4. Turn off the main power supply and disconnect the power line to avoid safety hazards.

[0082] 5. Check the status of each component and keep a record of equipment operation.

[0083] How this application works: The system uses a negative pressure fan 14 as the main power source to create a stable negative pressure in the pipeline. Multi-component zoned fiber suction components 3 are arranged at each fiber-producing station in the spinning workshop. The fiber suction hood 32 captures the fiber fluff in real time, and the air supply and pressure stabilization device 4 simultaneously supplies air to balance the air pressure. The fluff-containing airflow enters multiple cyclone separation components 17 through the conveying pipeline 2 for centrifugal pre-separation. Most of the fibers fall into the slag discharge cylinder 18. The initially clean airflow flows through the branch connecting pipe 10 into the conical guide hood 15, and then enters the filter box group 13 for three-stage fine filtration. The filtered clean air is discharged by the negative pressure fan 14. The separated and filtered fiber fluff falls into the pull-out box 162 of the collection box group 16 for centralized storage. During system operation, the air pressure sensor 35 and the wind speed sensor 36 monitor the working conditions in real time and automatically adjust the air supply and negative pressure to achieve stable, efficient, and intelligent fiber fluff absorption, separation, and collection throughout the entire process.
