Description

Technical Field

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

[0002] During textile production, a large amount of suspended pollutants, such as fibrous dust, short fibers, and volatile organic compounds, are continuously generated in the workshop environment. If these pollutants are discharged directly without efficient treatment, they will not only cause a decline in air quality and reduced visibility inside the workshop, affecting the health of operators and the normal operation of equipment, but will also pollute the external environment.

[0003] Currently, the commonly used single-channel fixed filtration devices typically require shutdown for manual cleaning or replacement after the filter screen becomes saturated, leading to production interruptions and impacting continuous operation efficiency. Furthermore, existing equipment often lacks real-time monitoring capabilities for changes in filtration resistance, making it impossible to accurately determine the degree of filter clogging. Cleaning and maintenance often rely on experience, easily resulting in premature cleaning leading to resource waste or delayed cleaning causing a surge in system resistance and increased energy consumption. In addition, some self-cleaning structures have complex designs, requiring airflow interruption during cleaning, making truly continuous filtration difficult. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an air filtration and environmental protection device for textile workshops to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: an air filtration environmental protection device for textile workshops, comprising a flow guiding mechanism, a filtration mechanism, and a cleaning mechanism. Two filtration mechanisms are symmetrically arranged, each having a filtration state and a cleaning state. The flow guiding mechanism is used to guide air from the textile workshop into one of the filtration mechanisms and to control the filtration mechanism into which air enters to switch to the filtration state and the filtration mechanism into which no air enters to switch to the cleaning state. The cleaning mechanism is used to perform cleaning operations on the filtration mechanism that has switched from the filtration state to the cleaning state.

[0006] Preferably, the air guide mechanism includes an air inlet, with an opening and closing component at the top and bottom of the air inlet, a transmission box fixedly connected to the surface of the air inlet, a rotating rod rotatably installed inside the transmission box, a motor fixedly installed inside the transmission box, and the output end of the motor fixedly connected to one end of the rotating rod.

One end of the rotating shaft passes through the inner wall of the guide tube and extends into the transmission box. A power transmission component is provided between one end of the rotating shaft and the rotating rod.

[0008] Preferably, the filtration mechanism includes a connecting pipe, a filter box, a fixed frame, and a connecting component. One end of the connecting pipe is fixedly connected to the guide pipe, and the other end of the connecting pipe is fixedly connected to the input end of the filter box. The output end of the filter box is equipped with a pressure sensing module.

[0009] Preferably, a first limit bracket and a second limit bracket are fixedly connected inside the connecting tube, an installation shaft is rotatably installed inside the connecting tube, a trigger plate is fixedly connected to the surface of the installation shaft, one end of the installation shaft passes through the inner wall of the connecting tube and extends outward, and a coil spring is sleeved on one end of the installation shaft.

[0010] Preferably, the filter box is equipped with a guide rail inside, and the fixed frame and the guide rail form a sliding guide fit. The filter plate is fixedly installed on the fixed frame, and the filter box is fixedly connected to a support frame outside.

[0011] Preferably, a positioning shaft is rotatably mounted on the support frame, a transmission shaft is rotatably mounted on the outside of the filter box, a second power transmission component is provided between the mounting shaft and the positioning shaft, and a third power transmission component is provided between the positioning shaft and the transmission shaft.

[0012] Preferably, the connecting assembly includes a central shaft, a first connecting rod, a second connecting rod, and an L-shaped rod. The central shaft is rotatably mounted on the support frame, and a power transmission component four is provided between the transmission shaft and the central shaft.

[0015] The beneficial effects of this invention are: This invention features a dual-filtration mechanism that can operate alternately, coupled with a pressure-sensing-based flow guiding mechanism and a cleaning mechanism that performs cleaning operations on the filtration mechanisms. This enables continuous, automated, and efficient operation of air filtration in textile workshops. Specifically, during operation, the equipment monitors the output air pressure changes of each filtration mechanism in real time via a pressure sensing module. When the filter plates accumulate more impurities, causing the resistance to rise to a set threshold, the flow guiding mechanism automatically switches the airflow channel, putting the saturated filter plate into a waiting-to-clean state. Simultaneously, another filter plate is activated to continue filtration, ensuring continuous and uninterrupted operation of the workshop's exhaust system and effectively preventing production interruptions. In the waiting-to-clean state, the cleaning mechanism uses a linear motion module to drive a scraper and a negative pressure adsorption device to mechanically clean the filter plate surface, eliminating the need for manual intervention and significantly reducing maintenance intensity and time costs. The overall structure, through a multi-stage linkage design, organically integrates airflow switching, filter plate retraction and extension, and cleaning execution, achieving a high degree of functional integration and reliable operational coordination. It is suitable for textile workshop environments with high dust concentrations and long operating cycles. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 2 This invention provides an air filtration environmental protection device for textile workshops, including a flow guiding mechanism 1, a filtration mechanism 2, and a cleaning mechanism 3. Two filtration mechanisms 2 are symmetrically arranged, and each filtration mechanism 2 has a filtration state and a cleaning state. The flow guiding mechanism 1 is used to guide the air in the textile workshop into one of the filtration mechanisms 2, and controls the filtration mechanism 2 into which air enters to switch to the filtration state and the filtration mechanism 2 into the cleaning state where no air enters. The cleaning mechanism 3 is used to perform a cleaning operation on the filtration mechanism 2 that has switched from the filtration state to the cleaning state.

[0029] Reference Figures 1 to 3 The air guide mechanism 1 includes an air inlet 11, with an opening and closing component at the top and bottom of the air inlet 11. A transmission box 12 is fixedly connected to the surface of the air inlet 11. A rotating rod 14 is rotatably installed inside the transmission box 12. A motor 13 is fixedly installed inside the transmission box 12. The output end of the motor 13 is fixedly connected to one end of the rotating rod 14.

[0030] The opening and closing assembly includes a guide tube 15, which is fixedly connected to the air inlet 11. A rotating shaft 16 is rotatably installed inside the guide tube 15. A valve plate 17 is fixedly connected to the surface of the rotating shaft 16. One end of the rotating shaft 16 passes through the inner wall of the guide tube 15 and extends into the transmission box 12. A power transmission component 18 is provided between one end of the rotating shaft 16 and the rotating rod 14. Preferably, the power transmission component 18 is a bevel gear transmission structure.

[0031] In use, the motor 13 can drive the rotating rod 14 to rotate around its own axis. The rotation of the rotating rod 14 drives the rotating shaft 16 to rotate synchronously around its own axis through the power transmission component 18. The rotation of the rotating shaft 16 drives the valve plate 17 to rotate synchronously around the axis of the rotating shaft 16. When the valve plate 17 in the bottom guide pipe 15 blocks the guide pipe 15, the top guide pipe 15 remains unobstructed. Air from the textile workshop is input through the air inlet 11 and passes through the top guide pipe 15. When the valve plate 17 in the top guide pipe 15 blocks the guide pipe 15, the bottom guide pipe 15 remains unobstructed. Air from the textile workshop is input through the air inlet 11 and passes through the bottom guide pipe 15.

[0032] In summary, the flow guiding mechanism 1, driven by the integrated motor 13, the rotating rod 14 in the transmission box 12, and the power transmission component 18, precisely controls the opening and closing state of the valve plate 17 in the two flow guiding pipes 15, realizing the automatic selection and switching of the airflow channel. This design is compact and responsive. Based on the control commands sent to the motor 13, it can close the airflow inlet of the saturated filter mechanism 2 and open the channel of the backup clean filter mechanism 2 at the same time. Thus, without interrupting the overall air intake, it can complete the seamless alternation of the main body of the filtration operation, providing core fluid control guarantee for the continuous operation of the equipment.

[0033] Reference Figures 1 to 8 The filter mechanism 2 includes a connecting pipe 21, a filter box 22, a fixed frame 24, and a connecting component 25. One end of the connecting pipe 21 is fixedly connected to the guide pipe 15, and the other end of the connecting pipe 21 is fixedly connected to the input end of the filter box 22. The output end of the filter box 22 is provided with a pressure sensing module 221. The pressure sensing module 221 integrates a pressure sensor and a microcontroller. The pressure sensor and the microcontroller are electrically connected, and the microcontroller is electrically connected to the motor 13. The pressure sensing module 221 is existing technology in the field of automation control and will not be described in detail here.

[0034] Limiting bracket 1 211 and limiting bracket 212 are fixedly connected inside the connecting tube 21. An installation shaft 26 is rotatably installed inside the connecting tube 21. A trigger plate 23 is fixedly connected to the surface of the installation shaft 26. One end of the installation shaft 26 passes through the inner wall of the connecting tube 21 and extends outward. A coil spring 29 is sleeved on one end of the installation shaft 26.

[0035] The filter box 22 is equipped with a guide rail 222 inside. The fixed frame 24 and the guide rail 222 form a sliding guide fit. The filter plate 241 is fixedly installed on the fixed frame 24. The filter box 22 is fixedly connected to the outside of the filter box 22. The positioning shaft 27 is rotatably installed on the support frame 223. The transmission shaft 28 is rotatably installed on the outside of the filter box 22. The second power transmission component 261 is provided between the mounting shaft 26 and the positioning shaft 27. The third power transmission component 271 is provided between the positioning shaft 27 and the transmission shaft 28. Preferably, the second power transmission component 261 is a chain drive structure and the third power transmission component 271 is a bevel gear drive structure.

[0036] The connecting assembly 25 includes a central shaft 251, a first connecting rod 252, a second connecting rod 253, and an L-shaped rod 254. The central shaft 251 is rotatably mounted on the support frame 223. A power transmission component 281 is provided between the transmission shaft 28 and the central shaft 251. One end of the first connecting rod 252 is fixedly connected to the surface of the central shaft 251, and the other end of the first connecting rod 252 is hinged to one end of the second connecting rod 253. The other end of the second connecting rod 253 is hinged to one end of the L-shaped rod 254, and the other end of the L-shaped rod 254 is fixedly connected to the fixed frame 24. Preferably, the power transmission component 281 is a chain drive structure.

[0037] In use, in the initial state, the valve plate 17 does not block the guide pipe 15 at the top of the air inlet 11, but blocks the guide pipe 15 at the bottom of the air inlet 11. Air in the textile workshop is drawn in through the air inlet 11 and enters the connecting pipe 21 located at the top by the exhaust fan. Under the action of air pressure, the trigger plate 23 and the mounting shaft 26 rotate as a whole around the axis of the mounting shaft 26. The trigger plate 23 changes from being in contact with the first limit frame 211 to being in contact with the second limit frame 212. As the mounting shaft 26 rotates, the coil spring 29 gradually tightens and the elastic force increases. The rotation of the mounting shaft 26 drives the positioning shaft 27 to rotate synchronously around its own axis through the second power transmission component 261. The rotation of the positioning shaft 27 drives the transmission shaft 28 to rotate synchronously around its own axis through the third power transmission component 271. The rotation of the transmission shaft 28 drives the central shaft 251 to rotate synchronously around its own axis through the fourth power transmission component 281. The rotation of the central shaft 251 drives the first connecting rod 252 to rotate synchronously around the axis of the central shaft 251. The rotation of the first connecting rod 252 drives the fixed rod 253 and the L-shaped rod 254 to rotate synchronously around the axis of the central shaft 251. The fixed frame 24 slides synchronously along the guide rail 222, and the fixed frame 24 gradually retracts into the filter box 22. The top filter mechanism 2 is in the filtering state, and the bottom filter mechanism 2 remains in the cleaning state. Air passes through the filter plate 241 on the fixed frame 24 and is discharged outward from the output end of the filter box 22. The filter plate 241 filters and adsorbs impurities in the air. As time goes by, the impurities accumulated on the filter plate 241 gradually increase. During this process, the air pressure sensing module 221 at the output end of the filter box 22 continuously monitors the air pressure. As impurities accumulate on the filter plate 241, the air pressure at the output end of the filter box 22 gradually decreases. When the air pressure decreases to the preset value, the air pressure sensing module 221 sends a command to the motor 13. Driven by the motor 13, the valve plate 17 blocks the guide pipe 15 at the top of the air inlet 11, and the valve plate 17 does not block the guide pipe 15 at the bottom of the air inlet 11. Afterwards, there is no more airflow in the connecting pipe 21 at the top, and the effect of air pressure is lost. The elastic force of the coil spring 29 is gradually released. The elastic force of the coil spring 29 drives the mounting shaft 26 to rotate in the opposite direction around its own axis. Similarly, the fixed frame 24 slides synchronously along the guide rail 222. The fixed frame 24 gradually extends outward from the filter box 22. The trigger plate 23 changes from being in contact with the second limit frame 212 to being in contact with the first limit frame 211 (when the trigger plate 23 is in contact with the first limit frame 211, one end of the fixed frame 24 is still resting in the guide rail 222 to ensure the stability of the sliding guide). The top filter mechanism 2 changes from the filtering state to the cleaning state. The air in the textile workshop is input through the air inlet 11 and enters the connecting pipe 21 at the bottom under the action of the exhaust fan. Under the action of air pressure, the bottom filter mechanism 2 changes from the cleaning state to the filtering state. Afterwards, the cleaning mechanism 3 cleans the top filter mechanism 2, which is in a state of needing cleaning. The filter plate 241 of the bottom filter mechanism 2 continues to filter the air. As impurities accumulate on the filter plate 241, the air pressure at the output end of the filter box 22 gradually decreases. When the air pressure drops to a preset value, the air pressure sensor module 221 sends a command to the motor 13. After receiving the command, the motor 13 drives the rotating rod 14 to rotate around its own axis. Similarly, for the guide pipe 15 at the top of the air inlet 11, the valve plate 17 does not block the guide pipe 15. For the guide pipe 15 at the bottom of the air inlet 11, the valve plate 17 blocks the guide pipe. After sealing 15, there is no more airflow in the bottom connecting pipe 21. Air enters the top connecting pipe 21. The bottom filter mechanism 2 switches from the filtering state to the cleaning state, and the top filter mechanism 2 switches from the cleaning state to the filtering state. Air enters the top connecting pipe 21 through the air inlet 11. The linear motion module pulls the air pipe 31 vertically through the support frame 34 to perform cleaning operation on the bottom cleaning filter mechanism 2. This cycle repeats, and the top filter mechanism 2 and the bottom filter mechanism 2 alternately filter the air discharged from the textile workshop.

[0038] In summary, the filtration mechanism 2 utilizes the power of the airflow itself as the initial trigger signal. Through a mechanical linkage system consisting of the trigger plate 23, the coil spring 29, and a series of power transmission components, the on / off state of the airflow is converted into the linear displacement of the fixed frame 24 within the filter box 22. This achieves an automatic state transition: "the filter plate 241 retracts to work when there is airflow and extends to await cleaning when there is no airflow." Combined with the real-time monitoring of filtration resistance by the air pressure sensor module 221, this mechanism can not only execute preset mechanical actions but also intelligently trigger the cleaning cycle based on the actual degree of clogging of the filter plate 241. This achieves a complete automated closed loop from state perception and judgment to execution, ensuring the long-term stability of filtration efficiency.

[0039] Reference Figures 1 to 9The cleaning mechanism 3 includes an air pipe 31 and a scraper 32. The air pipe 31 is fixedly connected to the vacuum cleaner via a flexible hose. Pneumatic nozzles 33 are fixedly connected to the top and bottom of the air pipe 31. Multiple pneumatic nozzles 33 are provided. The scraper 32 is fixedly installed on the air pipe 31. A support frame 34 is also fixedly connected to the air pipe 31. The support frame 34 is installed on the linear motion module.

[0040] In use, the linear motion module pulls the air pipe 31 to move vertically through the receiving frame 34 to clean the filter mechanism 2 which is in a state to be cleaned. During the cleaning process, along with the movement of the air pipe 31, the scraper 32 scrapes off the impurities on the filter plate 241, and the scraped impurities enter the vacuum cleaner through the pneumatic nozzle 33, the air pipe 31 and the hose.

[0041] In summary, the cleaning mechanism 3, as the key execution unit for realizing the self-cleaning function of this invention, drives the air pipe 31, which integrates a scraper 32 and multiple pneumatic nozzles 33, to perform precise reciprocating motion through a linear motion module. The scraper 32 is responsible for physically peeling off the fiber dust and impurities attached to the surface of the filter plate 241 to be cleaned, while the pneumatic nozzles 33, which work at the same time, quickly suck up the scraped pollutants under negative pressure and transport them through the hose to an external vacuum cleaner for centralized treatment. This "scraping and suction in one" cleaning method is highly efficient and thorough, and the cleaning process is carried out in an independent cleaning station, which does not affect the normal filtration operation of the other filtration mechanism 2 at all. This reduces the maintenance frequency and manual labor intensity, and ensures the cleanliness and reliability of the equipment during long-term operation.

[0042] The working principle of the present invention is as follows: In the initial state, the valve plate 17 does not block the guide pipe 15 at the top of the air inlet 11, but blocks the guide pipe 15 at the bottom of the air inlet 11.

[0043] Air in the textile workshop is drawn in through the air inlet 11 and enters the connecting pipe 21 located at the top by the exhaust fan. Under the action of air pressure, the trigger plate 23 and the mounting shaft 26 rotate as a whole around the axis of the mounting shaft 26. The trigger plate 23 changes from being in contact with the first limit frame 211 to being in contact with the second limit frame 212. As the mounting shaft 26 rotates, the coil spring 29 gradually tightens and the elastic force increases. The rotation of the mounting shaft 26 drives the positioning shaft 27 to rotate synchronously around its own axis through the second power transmission component 261. The positioning shaft 27 rotates and drives the transmission shaft 28 to rotate synchronously around its own axis through the power transmission component 3 271. The transmission shaft 28 rotates and drives the central shaft 251 to rotate synchronously around its own axis through the power transmission component 4 281. The central shaft 251 rotates and drives the connecting rod 1 252 to rotate synchronously around the axis of the central shaft 251. The connecting rod 1 252 rotates and drives the fixed frame 24 to slide synchronously along the guide rail 222 through the connecting rod 253 and the L-shaped rod 254. The fixed frame 24 gradually retracts into the filter box 22, and the top filter mechanism... 2. In the filtration state, the bottom filtration mechanism 2 remains in a state awaiting cleaning. Air passes through the filter plate 241 on the fixed frame 24 and is discharged outward from the output end of the filter box 22. The filter plate 241 filters and adsorbs impurities in the air. Over time, the impurities accumulated on the filter plate 241 gradually increase. During this process, the air pressure sensor module 221 at the output end of the filter box 22 continuously monitors the air pressure. As impurities accumulate on the filter plate 241, the air pressure at the output end of the filter box 22 gradually decreases. When the air pressure decreases to a preset value... After the value is received, the air pressure sensor module 221 sends a command to the motor 13. After receiving the command, the motor 13 drives the rotating rod 14 to rotate around its own axis. The rotation of the rotating rod 14 drives the rotating shaft 16 to rotate synchronously around its own axis through the power transmission component 18. The rotation of the rotating shaft 16 drives the valve plate 17 to rotate synchronously around the axis of the rotating shaft 16. For the guide pipe 15 at the top of the air inlet 11, the valve plate 17 blocks the guide pipe 15. For the guide pipe 15 at the bottom of the air inlet 11, the valve plate 17 does not block the guide pipe 15.

[0044] Afterwards, there is no more airflow in the connecting pipe 21 at the top, and the effect of air pressure is lost. The elastic force of the coil spring 29 is gradually released, and the elastic force of the coil spring 29 drives the mounting shaft 26 to rotate in the opposite direction around its own axis. Similarly, the fixed frame 24 slides synchronously along the guide rail 222. The fixed frame 24 gradually extends outward from inside the filter box 22. The trigger plate 23 changes from being in contact with the second limit frame 212 to being in contact with the first limit frame 211 (when the trigger plate 23 is in contact with the first limit frame 211, one end of the fixed frame 24 is still resting in the guide rail 222 to ensure the stability of the sliding guide). The top filter mechanism 2 changes from the filtering state to the cleaning state. The air in the textile workshop is input through the air inlet 11 and enters the connecting pipe 21 at the bottom under the action of the exhaust fan. Under the action of air pressure, the bottom filter mechanism 2 changes from the cleaning state to the filtering state.

[0045] Afterwards, the linear motion module pulls the air pipe 31 to move vertically through the receiving frame 34 to clean the filter mechanism 2 at the top. During the cleaning operation, the scraper 32 scrapes off the impurities on the filter plate 241 along with the movement of the air pipe 31, and the scraped impurities enter the vacuum cleaner through the pneumatic nozzle 33, the air pipe 31 and the hose.

[0046] The filter plate 241 of the bottom filter mechanism 2 continues to filter the air. As impurities accumulate on the filter plate 241, the air pressure at the output end of the filter box 22 gradually decreases. When the air pressure drops to a preset value, the air pressure sensing module 221 sends a command to the motor 13. After receiving the command, the motor 13 drives the rotating rod 14 to rotate around its own axis. Similarly, for the guide pipe 15 at the top of the air inlet 11, the valve plate 17 does not block the guide pipe 15; for the guide pipe 15 at the bottom of the air inlet 11, the valve plate 17 blocks the guide pipe 15. After that, the bottom connection... There is no more airflow inside pipe 21. Air enters the connecting pipe 21 at the top. The filter mechanism 2 at the bottom switches from the filtering state to the cleaning state, and the filter mechanism 2 at the top switches from the cleaning state to the filtering state. Air enters the connecting pipe 21 at the top through the air inlet 11. The linear motion module pulls the air pipe 31 to move vertically through the support frame 34 to perform cleaning operation on the filter mechanism 2 at the bottom in the cleaning state. This cycle repeats, and the filter mechanism 2 at the top and bottom alternately filters the air discharged from the textile workshop.
