Description

Technical Field

[0001] This invention relates to the field of air filtration technology, specifically an air filtration device for textile workshops. Background Technology

[0002] In the textile industry, with the continuous processes of spinning, weaving, and carding, a large amount of fibrous suspended matter inevitably disperses into the workshop air, mainly including short fibers, fine yarns, and lint. These substances are lightweight and easily float for extended periods under the influence of airflow, forming high-concentration dust and lint mixtures that cause pollution. This unique workshop environment not only seriously affects the operational precision and stability of production equipment but also poses a potential threat to the respiratory health of operators who are exposed to it for extended periods, easily inducing respiratory discomfort and even occupational diseases. Therefore, efficient and continuous filtration and purification of workshop air to maintain a clean and safe production environment has become an urgent need for textile enterprises to protect employee health and improve product quality and management levels.

[0003] To address the aforementioned issues, existing technologies commonly employ a simple solution: installing filter plates within ventilation or air purification equipment. The working principle involves forcing dust-laden air through a porous filter plate, where mechanical interception traps fibrous contaminants on its surface. However, textile workshops are characterized by large quantities of fibrous dust and its strong adhesion. During continuous operation, a large amount of fiber dust rapidly covers and clogs the pores of the filter plate within a very short time, leading to a sharp increase in air resistance, a significant decrease in ventilation volume, and a rapid decline in filtration efficiency. This not only renders the filtration function unsustainable but also increases fan energy consumption. To prevent equipment failure, frequent manual interruptions are necessary to disassemble, clean, or replace the filter plates. This maintenance method is not only cumbersome and consumes valuable production time, increasing labor costs, but also easily generates secondary dust during cleaning, affecting workshop cleanliness. Therefore, there is an urgent need for an innovative filtration solution that can achieve efficient self-cleaning or extend effective operating time. Summary of the Invention

[0004] This invention provides an air filtration device for textile workshops, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An air filtration device for textile workshops includes a support frame, an mounting plate in the middle of the support frame, a filter channel on the mounting plate, a filter screen inside the filter channel, a guide rail on the windward side of the mounting plate, a sliding seat slidably connected to the middle of the guide rail, a rotating shaft rotatably connected to the side of the sliding seat, a rotating barrel rotatably connected to the middle of the rotating shaft, and cleaning needles for removing deposits from the filter screen on the outer periphery of the rotating barrel. The device also includes a lifting drive mechanism, a telescopic drive mechanism, and a dust collection mechanism. The lifting drive mechanism, mounted on the support frame, drives the rotating barrel to move along the surface of the mounting plate and rotates it during this process. The telescopic drive mechanism, located on the side of the mounting plate, drives the cleaning needles to retract into the rotating barrel. The dust collection mechanism, located on the side of the mounting plate near the ground, cleans deposits from the outside of the rotating barrel.

[0006] As a preferred embodiment of the present invention, the rotating barrel has a hollow structure, and a torsion spring is provided inside the rotating barrel. One end of the torsion spring is connected to the inner wall of the rotating barrel, and the other end of the torsion spring is connected to the outer wall of the rotating shaft.

[0007] In a preferred embodiment of the present invention, the lifting drive mechanism includes a bearing seat mounted on a support frame. A rotating rod perpendicular to the guide rail is rotatably connected to the bearing seat. A transmission pulley is located at the end of the rotating rod. Two transmission pulleys on the same side of the mounting plate connect to both sides of a drive belt. A sliding seat is connected to the middle of the drive belt. A rotary drive device for driving the rotating rod is located on the side of the mounting plate away from the ground. A rotary drive rack parallel to the guide rail is located on the side of the mounting plate. A rotary driven gear meshing with the rotary drive rack is fitted around the outside of the rotating barrel.

[0008] As a preferred embodiment of the present invention, the telescopic drive mechanism includes a through hole disposed on the side wall of the rotating barrel, through which a cleaning needle passes. A fixing rod is fixedly connected to the outer wall of the rotating shaft. One end of the fixing rod away from the rotating shaft is rotatably connected to one end of a connecting rod, and the other end of the connecting rod is rotatably connected to the end of the cleaning needle near the rotating shaft. A telescopic drive rack is disposed on the side of the mounting plate near the ground. A telescopic driven gear is disposed on the outside of the rotating shaft and meshes with the telescopic drive rack. When the telescopic driven gear meshes with the telescopic drive rack, the angular velocity of the rotating shaft is greater than the angular velocity of the rotating barrel.

[0009] As a preferred embodiment of the present invention, the dust collection mechanism includes a sliding block disposed on the side of the guide rail near the ground, and a scraper plate disposed on the sliding block for cooperating with the rotating drum to scrape off the attached material. The sliding block is slidably connected to the guide rail, and a buffer spring cooperating with the sliding block is sleeved on the outside of the guide rail. A storage box is disposed on the side of the mounting plate near the ground, and the side of the storage box near the scraper plate has an open structure.

[0010] In a preferred embodiment of the present invention, a protective cover plate is fitted over the outside of the support frame, and a connecting flange is provided at the end of the protective cover plate. A discharge port is provided on the side of the protective cover plate closest to the ground, and a sealing cover plate is rotatably connected to the discharge port.

[0011] As a preferred embodiment of the present invention, an extension rod is provided on the side of the sliding seat away from the mounting plate, and a guide plate is provided at the end of the extension rod.

[0012] The present invention has the following advantages: 1. The rotating drum and cleaning needles achieve efficient, online physical cleaning of the filter screen. This design can promptly remove the fiber layer attached to the screen surface, effectively maintaining the filter screen's low air resistance and high filtration efficiency, and avoiding performance degradation and increased energy consumption caused by clogging.

[0013] 2. The device, through the automatic extension and retraction of the cleaning needles and the coordinated action of the scraper, reliably transfers and collects the detached contaminants into the storage box. This process is completed in a closed environment, and combined with the guide plate design, it fundamentally prevents the secondary re-entrainment of contaminants, thus protecting the workshop environment.

[0014] 3. The entire cleaning and dust collection process is highly automated, significantly reducing manual intervention. Users only need to start and stop the equipment as needed, and the equipment can automatically complete the entire lifecycle maintenance, greatly reducing the labor intensity and maintenance time costs of operators and improving equipment operation and maintenance efficiency.

[0015] 4. Each drive mechanism is compactly designed and precisely linked, with mechanical transmission such as gears and racks ensuring reliable operation. The overall structure is robust, and the use of standard interface flanges allows this device to be stably and easily integrated into various existing workshop ventilation systems, making it widely applicable.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In one embodiment, see Figure 1 , Figure 2 and Figure 4An air filtration device for textile workshops includes a support frame 1, which is composed of four parallel rod-shaped profiles arranged in a left-right direction. An mounting plate 5 is fixedly installed in the middle of the support frame 1, with its surface perpendicular to the airflow direction to optimize the interception effect. Airflow flows in from the right side of the device and passes through a filter channel 7 located above the mounting plate 5. The filter channel 7 contains a filter screen 8, whose core function is to intercept and filter contaminants such as short fibers, fine yarns, and lint contained in the airflow. The filter screen 8 is detachably connected to the filter channel 7, facilitating removal for cleaning or replacement after long-term operation, significantly reducing the complexity of subsequent maintenance.

[0028] Two vertically arranged guide rails 15 are installed on the windward side (i.e., the right side) of the mounting plate 5, located on the front and rear sides of the mounting plate 5 respectively. The guide rails 15 are slidably connected to the sliding seat 16, and the side of the sliding seat 16 is rotatably connected to a front-to-back rotating shaft 29 via bearings. A rotating barrel 18 is fitted in the middle of the rotating shaft 29, which is coaxially arranged with the rotating shaft 29 and can rotate relative to it. The circumferential sidewall of the rotating barrel 18 is provided with radially distributed cleaning needles 19. When performing cleaning tasks, the ends of these cleaning needles 19 extend out of the outer wall of the rotating barrel 18, allowing them to penetrate and peel off textile contaminants attached to the surface of the filter screen 8. Since the contaminants in the air of the textile workshop are mostly short fibers or fluffy materials, they will accumulate on the surface of the filter screen 8 to form a layered structure. When the cleaning needles 19 move with the rotating barrel 18 on the surface of the filter screen 8, they can effectively peel off the entire layer of contaminants, thereby achieving the purpose of efficient cleaning. This device also integrates a lifting drive mechanism 14, a telescopic drive mechanism 33, and a dust collection mechanism 20.

[0029] The lifting drive mechanism 14 is located on the right side of the support frame 1. Its function is to drive the rotating barrel 18 to move up and down along the surface of the mounting plate 5, and at the same time drive the rotating barrel 18 to rotate around its axis, so that the cleaning needle 19 can clean the surface of the filter screen 8 while rolling, thereby improving the peeling effect.

[0030] The telescopic drive mechanism 33 is located on the lower part of the right side of the mounting plate 5. Its function is to drive the cleaning needle 19 to retract into the rotating barrel 18 at a specific position, so that the cleaning needle 19 is separated from the rolled contaminants, creating conditions for the subsequent removal of contaminants from the rotating barrel 18.

[0031] The dust collection mechanism 20 is located at the lower end of the right side of the mounting plate 5 and is used to scrape off and collect textile pollutants attached to the outside of the rotating drum 18 to prevent them from being dispersed into the air again.

[0032] In one instance of this embodiment, please refer to Figure 2 and Figure 3To further optimize airflow and prevent secondary pollution, a horizontally extending extension rod 17 is fixedly connected to the right side of the sliding seat 16. An arc-shaped guide plate 6 with an opening facing left is installed at the end of the extension rod 17. The guide plate 6 covers the right side of the rotating barrel 18, preventing the airflow from directly blowing on the rotating barrel 18 during its up-and-down cleaning process, thereby preventing the stripped pollutants from being blown away by the airflow.

[0033] In one instance of this embodiment, please refer to Figure 2 and Figure 8 The rotating barrel 18 is a hollow cylindrical structure facing forward and backward, with torsion springs 35 installed at both its front and rear ends. One end of the torsion spring 35 is connected to the inner wall of the rotating barrel 18, and the other end is connected to the outer wall of the rotating shaft 29. When the torsion spring 35 is in its natural state, the cleaning needle 19 remains extended under the action of the spring torsion, and the rotating shaft 29 and the rotating barrel 18 rotate synchronously in this state.

[0034] In one instance of this embodiment, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 The lifting drive mechanism 14 includes a bearing seat 9 mounted on the right side of the support frame 1, and the bearing seat 9 is rotatably connected to the front and rear sides of the rotating rod 11. The upper and lower rotating rods 11 are located at the upper and lower parts of the support frame 1, respectively. A transmission pulley 10 is mounted at both the front and rear ends of each rotating rod 11. A ring-shaped drive belt 12 is sleeved between the corresponding upper and lower transmission pulleys 10, meaning that a belt drive system is configured on each of the front and rear sides of the support frame 1. The middle part of the drive belt 12 is fixedly connected to the side of the sliding seat 16. A rotary drive device 13 (such as a drive motor) is mounted on the upper right side of the mounting plate 5, and its output shaft is connected to the upper rotating rod 11 via belt drive. Starting the rotary drive device 13 can drive the rotating rod 11 to rotate, thereby pulling the sliding seat 16 and the rotating barrel 18 to reciprocate up and down via the drive belt 12.

[0035] Vertically arranged rotary drive racks 25 are fixedly installed on the front and rear sides of the mounting plate 5. Corresponding to the position of the rotary drive racks 25, rotary driven gears 26 are sleeved at the front and rear ends of the rotating barrel 18. When the rotating barrel 18 moves up and down under the drive of the lifting mechanism 14, the rotary driven gears 26 mesh with the fixed rotary drive racks 25, forcing the rotating barrel 18 to rotate around its axis while moving, so that the cleaning needles 19 can rotate around the center of the rotating barrel 18 and clean in a rolling manner.

[0036] In one instance of this embodiment, please refer to Figure 4 , Figure 6 , Figure 7 and Figure 8The telescopic drive mechanism 33 includes several through holes 30 formed in the side wall of the rotating drum 18. The cleaning needle 19 passes through these through holes 30 and can move axially along the holes. A fixed rod 31 is fixedly connected to the outer wall of the rotating shaft 29. The end of the fixed rod 31 is rotatably connected to one end of the connecting rod 32 via a hinge. The other end of the connecting rod 32 is hinged to the near-axial end of the cleaning needle 19. Thus, when the rotating shaft 29 rotates relative to the rotating drum 18, the cleaning needle 19 can be driven to telescopically move by the crank-slider mechanism composed of the fixed rod 31 and the connecting rod 32. On the lower part of the right side of the mounting plate 5, a telescopic drive rack 27 is installed parallel to the rotating drive rack 25. Telescopic driven gears 28 are installed at the front and rear ends of the rotating shaft 29 respectively. When the rotating drum 18 moves to the lower working position, the telescopic driven gear 28 and the telescopic drive rack 27 engage. Through a specific design of the number of teeth, in this state, the rotational angular velocity of the rotating shaft 29 will be greater than the angular velocity of the rotating barrel 18, causing the rotating shaft 29 to rotate relative to the rotating barrel 18. When the rotating shaft 29 moves downward, this relative rotation drives the cleaning needle 19 to retract into the rotating barrel 18 through the linkage 32 mechanism; when the rotating shaft 29 moves upward, it drives the cleaning needle 19 to extend.

[0037] In one instance of this embodiment, please refer to Figure 2 , Figure 4 and Figure 5 The dust collection mechanism 20 includes a sliding block 22 slidably fitted onto the lower part of the guide rail 15. A buffer spring 21 is fitted onto the lower part of the guide rail 15, with its lower end abutting against the bottom end of the guide rail 15 and its upper end abutting against the lower surface of the sliding block 22. A scraper 23 facing forward and backward is installed on the side of the sliding block 22. When the rotating drum 18 descends to its lower position, the buffer spring 21 pushes the sliding block 22 upward, causing the scraper 23 to adhere tightly to the outer wall of the rotating drum 18. At this time, the cleaning needle 19 has retracted, the rotating drum 18 continues to rotate, and the scraper 23 can scrape off the textile contaminants attached to its outer wall. A storage box 24 is installed on the lower part of the right side of the mounting plate 5, with an open top structure to receive the contaminants scraped off by the scraper 23.

[0038] In one instance of this embodiment, please refer to Figure 1A protective cover 34 is installed on the outside of the support frame 1. The protective cover 34 is made of bent and welded metal plate or fixed to the support frame 1 by bolts, forming a through-channel structure. Connecting flanges 2 are provided at both ends of the protective cover 34 for connecting to the workshop ventilation ducts that the filtration device needs to access. A discharge port 3 is opened on the lower side of the protective cover 34, positioned directly below the storage box 24. A hinged sealing cover 4 is installed at the discharge port 3. During normal operation, the sealing cover 4 is closed, ensuring stable airflow inside the protective cover 34. When periodic cleaning is required, the sealing cover 4 can be opened, and the storage box 24 can be removed for centralized treatment of collected contaminants.

[0039] In this embodiment, the air filtration device is first connected in series to the ventilation duct system of the textile workshop through the connecting flanges 2 at both ends of the protective cover plate 34.

[0040] Filtration process: Airflow enters from the right side of the mounting plate 5 and passes through the filter screen 8 inside the filter channel 7 from right to left. The filter screen 8 intercepts and filters suspended pollutants such as short fibers, fine yarns, and lint in the airflow, while the clean air continues to flow to the left. During this process, the intercepted pollutants gradually adhere to the right surface of the filter screen 8.

[0041] Cleaning process: The rotary drive device 13 is activated, driving the sliding seat 16 to move the rotating drum 18 upwards. During this upward movement, the driven gears 26 at both ends of the rotating drum 18 mesh with the fixed rotary drive rack 25, forcing the rotating drum 18 to rotate simultaneously. The cleaning needles 19 on its outer wall then pierce and peel off the layered contaminants adhering to the surface of the filter screen 8. These peeled contaminants are partially wrapped around the outside of the rotating drum 18. When the sliding seat 16 reaches its upper limit position, the rotary drive device 13 reverses, driving it downwards. During the downward movement, the rotating drum 18 continues to rotate, and the cleaning needles 19 clean the surface of the filter screen 8 again. One such cycle completes a thorough cleaning of the surface of the filter screen 8. This cleaning operation can be started periodically or as needed, depending on the actual level of contamination.

[0042] Dust collection process: As the rotating drum 18 descends to the lower working area, the telescopic driven gears 28 at both ends of the rotating shaft 29 engage with the fixed telescopic drive rack 27. Due to the transmission ratio design, the angular velocity of the rotating shaft 29 is momentarily greater than that of the rotating drum 18, causing the rotating shaft 29 to rotate relative to the rotating drum 18. Through the cooperation of the fixed rod 31 and the connecting rod 32, the cleaning needle 19 is completely retracted into the rotating drum 18. At the same time, the outer wall of the rotating drum 18 is in close contact with the scraper 23 supported by the buffer spring 21. The continuous rotation of the rotating drum 18 allows the scraper 23 to effectively scrape off the contaminants rolled around its outer wall. The scraped-off contaminants fall directly into the storage box 24 below, completing the collection.

[0043] This invention provides an air filtration device for textile workshops. By designing a rotating drum 18 with retractable cleaning needles 19, it can roll and clean the surface of the filter screen 8, efficiently peeling off and transferring contaminants adhering to the screen to the rotating drum 18, effectively ensuring the long-term permeability and filtration efficiency of the filter screen 8. Furthermore, by setting a telescopic drive mechanism 33, the cleaning needles 19 automatically retract when the rotating drum 18 moves downwards. This greatly facilitates the dust collection mechanism 20 in thoroughly scraping away contaminants wrapped around the outside of the rotating drum 18 and collecting them into the storage box 24. The entire process achieves full automation from filtration and automatic cleaning to contaminant collection, significantly improving the equipment's self-cleaning ability and long-term operational stability, and reducing the frequency and intensity of manual maintenance.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
