Description

Technical Field

[0001] This invention relates to the field of baghouse dust collection technology, specifically to a baghouse dust collector with a flow guiding function. Background Technology

[0002] Traditional baghouse dust collectors often suffer from uneven airflow distribution, leading to localized filter bag damage, numerous dust accumulation dead zones, and frequent shutdowns for filter bag replacement, resulting in low maintenance efficiency and high costs. As industrial dust removal demands increased equipment stability and ease of maintenance, there is an urgent need to address the pain points of rapid filter bag wear and cumbersome maintenance caused by turbulent airflow. Therefore, baghouse dust collectors with airflow guiding functions have emerged. By optimizing airflow distribution through a guiding structure, they reduce filter bag damage and simplify the internal layout, making filter bag disassembly, assembly, and dust cleaning more convenient, thus meeting the needs of efficient operation and maintenance and cost reduction.

[0003] Patent CN219879430U discloses a bag filter with a flow guiding function, including a bag filter body. An inlet pipe is located at the bottom of one side surface of the bag filter body, and an outlet pipe is located at the top of the other side surface. A flow guiding assembly is fixedly connected to the bag filter body. The flow guiding assembly includes a diverter pipe, which is fixed to the bottom of one side surface of the bag filter body. The inlet pipe is fixed to the diverter pipe, and gas flow meters are symmetrically fixedly connected to the diverter pipe. A collector pipe is fixedly connected to the top of the other side surface of the bag filter body. A partition is fixedly connected inside the bag filter body. This patent, through the design of the flow guiding assembly, allows for the cleaning or replacement of the dust collector filter element inside the equipment without stopping the equipment during operation, thereby improving the dust removal efficiency of the device to a certain extent.

[0004] However, when the above-mentioned device is in use, it is difficult to rotate and scrape the dust collector bag simultaneously during the process of guiding the gas flow. At the same time, it is difficult to clean and collect the dust particles in the dust collector bag during subsequent use, which leads to a decrease in the dust removal speed and affects the subsequent dust removal efficiency and quality. Therefore, a bag dust collector with a flow guiding function is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a bag filter with a flow guiding function to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a bag filter with a flow guiding function, comprising a base, an exhaust box mounted on the base, an exhaust fan mounted on the base, a motor mounted on the exhaust box, a connecting pipe mounted on the exhaust fan, a rotating column rotatably connected to the inner wall of the exhaust box, a flow guiding hopper fixedly connected to the inner wall of the exhaust box, a fixing rod fixedly connected to the circumferential surface of the rotating column, a sealing plate fixedly connected to the bottom of the fixing rod, a guide plate rotatably connected to the bottom of the flow guiding hopper, a connecting plate fixedly connected to the bottom of the guide plate, and a connecting plate at the bottom of the connecting plate.

An exhaust pipe is located on the right side of the discharge box, ensuring that the discharged gas can only enter the subsequent dust collection components through another guide hopper. In this case, one of the movable filter units of the device may fail, allowing for replacement of parts without shutting down the device. This enables gas diversion and improves the dust collection efficiency of the device.

[0007] Preferably, the inner wall of the discharge box is provided with a speed-up mechanism to accelerate the gas flow rate, and the inner wall of the discharge box is provided with an anti-clogging mechanism for pushing dust particles.

[0009] Preferably, the speed-up mechanism includes a second fixed rod, which is fixedly connected to the circumferential surface of the first fixed rod. A guide block is fixedly connected to the inner wall of the second fixed rod, and a sealing ring is fixedly connected to the circumferential surface of the sealing plate. This allows the guide block to indirectly extend the length of the guide slope of the guide bucket, thereby accelerating the gas flow rate, increasing the air duct flow efficiency, and directly improving the gas dust removal effect of the device.

A fixing ring is fixedly connected to the telescopic end of the elastic telescopic rod, and a ash discharge inclined block is fixedly connected to the top of the fixing ring.

[0012] Preferably, the anti-clogging mechanism includes a filter plate, which is fixedly connected to the inner wall of the discharge box. A slip ring is slidably connected to the inner wall of the discharge box. A connecting rod is rotatably connected to the inner wall of the slip ring via a torsion spring. A connecting block is rotatably connected to the inner wall of the connecting rod. A roller is rotatably connected to the inner wall of the connecting block. This causes the filter plate to vibrate accordingly, which can shake off dust particles on its own filter surface, improve the dust removal effect of the device, and prevent dust and particles from accumulating on the surface of the filter plate and causing blockage, thus affecting the smoothness of the subsequent air duct.

[0013] Preferably, the anti-clogging mechanism further includes a rotating column, which is fixedly connected to the circumferential surface of the roller. Brush bristles are fixedly connected to the circumferential surface of the rotating column.

At this time, one of the moving filter units of the device can fail, and the parts can be replaced without stopping the device. It can guide the gas flow and improve the dust collection effect of the device. The scraper ring can scrape the surface of the dust collector bag, which can enhance dust removal, reduce the probability of clogging, and ensure that the dust collector bag and the dust-laden airflow are in full contact, avoiding local airflow dead zones. At the same time, it can reduce the concentrated adhesion of dust in a certain area of ​​the bag, so that the filtration area is used evenly and the dust collection effect of the device is improved.

[0016] 2. This baghouse dust collector with a flow guiding function, through the coordinated movement of the fixed rod, guide inclined block, sealing ring, elastic telescopic rod, fixed ring, ash discharge inclined block, and top pressure column, allows the guide inclined block to indirectly extend the length of the flow guiding slope of the guide bucket, thereby accelerating the gas flow speed, expanding the air duct flow efficiency, and directly improving the gas dust removal effect of the device. Dust and particles on the inner wall of the dust collector bag can be discharged through the opening of the ash discharge inclined block, improving the subsequent dust particle collection efficiency and indirectly extending the service life of the device, preventing excessive dust particles on the inner wall of the dust collector bag from affecting the service life of the parts.

[0017] 3.

[0020] 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.

[0021] Please see Figures 1-9 One embodiment of the present invention is as follows: a bag filter with a flow guiding function includes a base 1, an exhaust box 2 installed on the base 1, an exhaust fan 3 installed on the base 1, a motor installed on the exhaust box 2, a connecting pipe installed on the exhaust fan 3, a rotating column 4 rotatably connected to the inner wall of the exhaust box 2, a flow guiding hopper 5 fixedly connected to the inner wall of the exhaust box 2, a fixing rod 8 fixedly connected to the circumferential surface of the rotating column 4, a sealing plate 9 fixedly connected to the bottom of the fixing rod 8, a guide plate 10 rotatably connected to the bottom of the flow guiding hopper 5, a connecting plate 11 fixedly connected to the bottom of the guide plate 10, a fixing frame 12 fixedly connected to the bottom of the connecting plate 11, a dust collector bag 13 fixedly connected to the circumferential surface of the fixing frame 12, a gear 14 fixedly connected to the circumferential surface of the guide plate 10, a gear 2 15 fixedly connected to the circumferential surface of the rotating column 4, a movable ring 16 movably connected to the circumferential surface of the rotating column 4, a scraper ring 17 fixedly connected to the inner wall of the movable ring 16, and an exhaust pipe provided on the right side of the exhaust box 2. When the device is in use, the operator first starts the exhaust fan 3. The exhaust fan 3, after starting, draws outside gas into the discharge box 2 through the connecting pipe. The discharged gas enters the guide plate 10 through the guide bucket 5, and then enters the connecting plate 11 through the guide plate 10 again. The gas in the connecting plate 11 can reach the inside of the fixed frame 12. At this time, the dust collector bag 13 can isolate the dust particles in the gas in the fixed frame 12. The gas can be discharged through the exhaust pipe, while the dust particles in the gas will remain on the inner wall of the dust collector bag 13. When parts need to be replaced, at this time... The motor will start, and the output of the motor will drive the rotating column 4 to rotate. The rotation of the rotating column 4 will drive the fixed rod 8 to rotate, and the rotation of the fixed rod 8 will drive the sealing plate 9 to rotate. When the sealing plate 9 rotates to a suitable angle, the sealing plate 9 can seal one of the guide buckets 5 inside the discharge box 2. At this time, the discharged gas can only enter the subsequent dust removal parts through the other guide bucket 5. At this time, one of the moving filter units of the device can fail. The parts can be replaced without stopping the device. The gas can be guided, which can improve the dust removal effect of the device. The inner wall of the discharge box 2 is provided with a speed-up mechanism 6 for accelerating the gas flow rate, and an anti-clogging mechanism 7 for pushing dust particles. The connecting pipe is connected to the discharge box 2. The rotating column 4 is fixedly connected to the output end of the motor. The sealing plate 9 is in contact with the discharge box 2 and is used to seal the opening of the discharge box 2. The guide bucket 5 is connected to the guide plate 10. The guide plate 10 is connected to the connecting plate 11. The connecting plate 11 is connected to the fixed frame 12. The moving ring 16 is slidably connected to the inner wall of the discharge box 2. Gear 14 and gear 2 15 mesh. When the device is started, the rotation of the rotating column 4 drives the second gear 15 to rotate, which in turn drives the first gear 14 to rotate. The rotation of the first gear 14 drives the guide plate 10 to rotate, which in turn drives the connecting plate 11 to rotate. The connecting plate 11 drives the fixed frame 12 to rotate, which in turn drives the dust collector bag 13 to rotate. At the same time, the rotation of the rotating column 4 drives the moving ring 16 to rotate, which in turn drives the scraper ring 17 to rotate. However, at this time, the moving ring 16 slides on the inner wall of the discharge box 2. The limiting of the moving ring 16 by the discharge box 2 causes the moving ring 16 to move up and down only through the reciprocating groove on the surface of the rotating column 4 during the rotation of the rotating column 4. The movement of the moving ring 16 will drive the scraper ring 17 to move. The scraper ring 17 can scrape the surface of the dust collector bag 13, which can enhance dust removal, reduce the probability of clogging, and allow the dust collector bag 13 to fully contact the dust-laden airflow, avoid local airflow dead zones, and reduce the concentrated adhesion of dust in a certain area of ​​the bag, so that the filtration area is used evenly and the dust removal effect of the device is improved. Overall working principle: When the sealing plate 9 is rotated to a suitable angle, it can seal one of the guide buckets 5 inside the discharge box 2. At this time, the discharged gas can only enter the subsequent dust removal parts through the other guide bucket 5. At this time, one of the movable filter units of the device can fail. The parts can be replaced without stopping the device. It can guide the gas flow, improve the dust removal effect of the device, enhance dust removal, reduce the probability of clogging, and allow the dust collector bag 13 to fully contact the dust-laden airflow, avoiding local airflow dead zones. At the same time, it reduces the concentrated adhesion of dust in a certain area of ​​the bag, making the filtration area evenly utilized and improving the dust removal effect of the device.

[0022] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the speed-up mechanism 6 includes a second fixed rod 601, which is fixedly connected to the circumferential surface of the first fixed rod 8. A guide inclined block 602 is fixedly connected to the inner wall of the second fixed rod 601, and a sealing rubber ring 603 is fixedly connected to the circumferential surface of the sealing plate 9. When the device is in use, the rotation of the first fixed rod 8 will cause the second fixed rod 601 to rotate, which in turn will cause the guide inclined block 602 to rotate synchronously. After rotating a certain angle, the guide inclined block 602 can be located at the top of the guide bucket 5. At the same time, the rotation of the sealing plate 9 will cause the sealing ring 603 to rotate. The sealing ring 603 can improve the stable sealing effect during the sealing process of the sealing plate 9 on the guide bucket 5. After the guide inclined block 602 moves, it can indirectly extend the length of the guide inclined surface of the guide bucket 5, which can accelerate the gas flow speed, expand the air duct flow efficiency, and directly improve the gas dust removal effect of the device. The speed-up mechanism 6 also includes an elastic telescopic rod 604, which is fixedly connected to the bottom of the dust collector bag 13. A fixed ring 605 is fixedly connected to the telescopic end of the elastic telescopic rod 604. A ash discharge inclined block 606 is fixedly connected to the top of the fixed ring 605. A top pressure column 607 is fixedly connected to the bottom of the moving ring 16. A sealing ring 603 contacts the discharge box 2 and is used to improve the sealing effect of the sealing plate 9. A guide inclined block 602 contacts the discharge box 2 and is used to accelerate the movement speed of the gas. A ash discharge inclined block 606 contacts the fixed frame 12 and is used to discharge dust. The fixed ring 605 is located on the movement trajectory of the top pressure column 607 and the top pressure column 607 is used to push the fixed ring 605 to move. When the device is started, as the scraper ring 17 moves downward, the movement of the scraper ring 17 will drive the top pressure column 607 to move synchronously. After moving a certain distance, the top pressure column 607 will contact the fixed ring 605 and squeeze and push the fixed ring 605 to move downward. The downward movement of the fixed ring 605 will stretch the elastic telescopic rod 604 and drive the ash discharge inclined block 606 to move synchronously. After the ash discharge inclined block 606 moves a certain distance, it can open the opening at the bottom of the dust collector bag 13. At this time, the dust and particles on the inner wall of the dust collector bag 13 can be discharged through the opening of the ash discharge inclined block 606, which can improve the subsequent dust particle collection efficiency and indirectly improve the service life of the device, avoiding excessive dust particles on the inner wall of the dust collector bag 13, which will affect the service life of the parts. The anti-clogging mechanism 7 includes a filter plate 701, which is fixedly connected to the inner wall of the discharge box 2. A slip ring 702 is slidably connected to the inner wall of the discharge box 2. A connecting rod 703 is rotatably connected to the inner wall of the slip ring 702 via a torsion spring. A connecting block 704 is rotatably connected to the inner wall of the connecting rod 703. A roller 705 is rotatably connected to the inner wall of the connecting block 704. When the device is started, after the fixed ring 605 moves downward a certain distance, it will contact the slip ring 702 and squeeze and push the slip ring 702 to move synchronously. The movement of the slip ring 702 will drive the connecting rod 703 to move. At this time, the connecting rod 703 will change its own angle synchronously during the movement. The connecting rod 703 can drive the connecting block 704 to move. The movement of the connecting block 704 will drive the roller 705 to move. After the roller 705 moves a certain distance, it will contact the surface of the filter plate 701. At this time, the roller 705 can rotate and roll on the surface of the filter plate 701 through the friction generated by the contact. Under this operation, the filter plate 701 will vibrate accordingly, which can shake off the dust particles on its own filter surface, improve the dust removal effect of the device, and prevent dust and particles from accumulating on the surface of the filter plate 701 and causing blockage, which would affect the smoothness of the subsequent air duct. The anti-clogging mechanism 7 also includes a rotating column 706, which is fixedly connected to the circumferential surface of the roller 705. The circumferential surface of the rotating column 706 is fixedly connected to bristles 707. The slip ring 702 is located on the movement trajectory of the fixed ring 605, and the fixed ring 605 is used to push the slip ring 702 to move. The roller 705 is in contact with the discharge box 2. The filter plate 701 is located on the movement trajectory of the roller 705, and the roller 705 is used to make the filter plate 701 vibrate. The filter plate 701 is located on the movement trajectory of the bristles 707. As the roller 705 moves and rotates, its movement and rotation simultaneously drive the rotating column 706 to move and rotate. The rotation of the rotating column 706 then drives the brush bristles 707 to move and rotate. During this process, the brush bristles 707 remain in contact with the filter plate 701. The brush bristles 707 can clean the dust on the surface of the filter plate 701, improving the effectiveness of the device, avoiding manual cleaning costs, and reducing the frequency of parts replacement. Overall working principle: The guide ramp 602 can indirectly extend the length of the guide ramp of the guide bucket 5, which can accelerate the gas flow speed, expand the air duct flow efficiency, and directly improve the gas dust removal effect of the device. Dust and particles on the inner wall of the dust collector bag 13 can be discharged through the opening of the ash discharge ramp 606, which can improve the subsequent dust particle collection efficiency and indirectly improve the service life of the device. It can also prevent excessive dust particles on the inner wall of the dust collector bag 13, which would affect the service life of the parts. It can also shake off the dust particles on its own filter surface, improve the dust removal effect of the device, and prevent dust and particles from accumulating on the surface of the filter plate 701 and causing blockage, which would affect the smoothness of the subsequent air duct. The bristles 707 can clean the dust on the surface of the filter plate 701, improve the use effect of the device, avoid manual cleaning costs, and reduce the number of parts replacements.
