Abstract

This invention discloses a baghouse pulse dust collector with good dust removal effect, belonging to the field of mechanical dust removal technology. It includes a tank, an installation chamber, and a movable disc. The movable disc has multiple sets of pre-drilled holes, each containing a movable tube. Each movable tube extends into the tank and has a jet nozzle installed at one end. A pulse air pump is installed at the upper end of the installation chamber, and a second outlet pipe is installed at the outlet of the pulse air pump. Multiple sets of filter bags are installed inside the tank. By incorporating the movable disc, movable tubes, and jet nozzles, the movable disc moves downwards, causing the movable tubes and jet nozzles to move downwards, which in turn causes multiple limiting plates to move downwards. As the jet nozzles continue to move downwards, they enter the interior of the filter bags, improving the cleaning effect of the airflow from the jet nozzles on the outer walls of the filter bags and extending the service life of the filter bags.

Description

Technical Field

[0001] This invention relates to the field of mechanical dust removal technology, specifically to a bag pulse dust collector with good dust removal effect. Background Technology

[0002] Bag pulse dust collectors are a type of equipment commonly used in industrial dust removal. They mainly remove particulate matter from the air through bag filtration technology and pulse jet cleaning principle. Bag pulse dust collectors have high filtration efficiency and adaptability, and are widely used in industries such as cement, fertilizer, power, and metallurgy.

[0003] The working principle of a belt pulse dust collector is as follows: dust-laden gas enters the baghouse dust collector through the inlet, passes through the filter media of the bags, and larger dust particles are captured on the surface of the bags. The purified air is discharged from the outlet. The bags are usually made of polyester, polypropylene, or other filter materials, which can effectively intercept dust particles. As the filtration process proceeds, dust gradually accumulates on the surface of the filter bags. When the dust accumulation on the surface of the filter bags reaches a certain level, a short, high-pressure airflow is generated through the pulse valve and instantly sprayed onto the surface of the bags, peeling off the attached dust. The cleaned dust is collected in the dust hopper, which improves the dust removal efficiency of the belt pulse dust collector and extends the service life of the filter bags.

[0004] In the existing technology, when cleaning the dust collector bag, because the blow pipe is located at the top of the dust collector bag, the lower side of the dust collector bag is less affected by the wind. As a result, the dust adhering to the lower surface of the dust collector bag is difficult to clean, which reduces the dust removal efficiency of the belt pulse dust collector and the service life of the dust collector bag. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a bag filter pulse dust collector with good dust removal effect to solve the technical problems in the background art mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bag pulse dust collector with good dust removal effect, comprising a tank, an installation chamber and a movable disc, wherein the installation chamber is installed at the upper end of the tank, and the movable disc is movably installed inside the installation chamber;

[0007] The movable plate has multiple sets of reserved holes, each set of reserved holes is equipped with a movable pipe, and each set of movable pipes is equipped with a jet nozzle at one end extending into the tank. A pulse air pump is installed at the upper end of the installation chamber, and a second air outlet pipe is installed at the air outlet of the pulse air pump, with one end of the second air outlet pipe extending into the installation chamber. Multiple sets of cloth bag bodies are installed inside the tank.

[0008] A drive motor is installed at the upper end of the installation chamber. Two sets of drive shafts are movably installed inside the installation chamber. One set of drive shafts is connected to the output end of the drive motor. The two sets of drive shafts are connected by a synchronous belt. The outer walls of both sets of drive shafts are threaded to the inner wall of the movable disc.

[0009] By adopting the above technical solution, the problem of poor cleaning at the lower end of the pulse bag is solved. The drive motor starts, driving a set of drive shafts to rotate. The two sets of drive shafts are connected by a synchronous belt and rotate synchronously. The outer walls of the two sets of drive shafts are threadedly connected to the inner wall of the movable disc. Therefore, the movable disc moves downward, thereby driving multiple sets of movable pipes and multiple sets of jet heads to move downward, which in turn drives multiple sets of limit plates to move downward. After the multiple sets of jet heads continue to move downward, they enter the interior of multiple sets of bag bodies, improving the cleaning effect of the airflow from the multiple sets of jet heads on the impurities on the outer wall of the multiple sets of bag bodies and extending the service life of the dust collector bags.

[0010] The present invention is further configured such that an air inlet pipe is installed at one end of the tank, a first air outlet pipe is installed at the other end of the tank, and a discharge port is provided at the bottom of the tank.

[0011] Preferably, the dust-laden gas enters the tank through the inlet pipe, the filtered gas is discharged through the outlet pipe, and the impurities are discharged through the outlet.

[0012] The present invention is further configured such that an installation plate is installed inside the tank, and multiple sets of brackets are installed on the inner wall of the installation plate, and multiple sets of cloth bag bodies are sleeved on the outer wall of the multiple sets of brackets.

[0013] Preferably, multiple sets of brackets support multiple sets of fabric bag bodies respectively.

[0014] The present invention is further configured such that multiple sets of bearing seats are installed on the outer walls of the multiple sets of jet heads, and a torsion spring is provided at one end of the bearing inside the multiple sets of bearing seats, and a movable rod is movably installed inside the multiple sets of bearing seats.

[0015] Preferably, the bearings inside the multiple sets of bearing seats limit the movement of the multiple sets of moving rods.

[0016] The present invention is further configured such that one end of each of the multiple sets of movable rods is movably connected to the upper outer wall of the multiple sets of brackets and the inner wall of the multiple sets of cloth bag bodies, and the outer wall of each of the multiple sets of movable rods is provided with a rubber protective layer.

[0017] Preferably, the multiple sets of movable rods are inclined downwards before entering the multiple sets of bag bodies. The lower ends of the multiple sets of movable rods contact the upper ends of the multiple sets of supports, causing the multiple sets of movable rods to tilt upwards. Then, the multiple sets of movable rods enter the multiple sets of bag bodies and adhere to the inner walls of the multiple sets of bag bodies. The filtered airflow enters the bag body and creates a certain impact on the movable rods, causing the movable rods to tilt towards the movable tube. At this time, the torsion spring at one end of the bearing drives the bearing to reset and rotate, thereby causing the movable rods to strike the inner wall of the bag body, assisting in the removal of impurities remaining on the outer wall of the bag body. The rubber protective layer protects the inner walls of the multiple sets of bag bodies.

[0018] The present invention is further configured such that limiting plates are symmetrically installed on the outer wall of one end of the multiple sets of movable tubes, and limiting grooves are symmetrically opened on the inner wall of the multiple sets of brackets, and the outer wall of the multiple sets of limiting plates is movably connected to the inner wall of the multiple sets of limiting grooves respectively.

[0019] Preferably, multiple sets of limiting plates 12 enter multiple sets of limiting grooves respectively, which improves the stability of one end of the movable tube.

[0020] The invention is further configured such that a drive shaft is movably installed inside the tank, and one end of the drive shaft extending into the inner wall of the tank is connected to a set of drive shafts by a synchronous belt.

[0021] Preferably, two sets of drive shafts rotate, with one set of drive shafts connected to the transmission shaft via a synchronous belt, and the transmission shaft rotating.

[0022] The present invention is further configured such that a transmission gear is installed at one end of the transmission shaft extending into the inner wall of the mounting plate, a movable ring is movably installed at the bottom end of the mounting plate, and a toothed ring is installed on the inner wall of the movable ring, and the toothed ring is meshed with the transmission gear.

[0023] Preferably, the drive shaft rotates, driving the drive gear to rotate. The drive gear meshes with the gear ring, and the gear ring rotates, thereby driving the movable ring to rotate.

[0024] The present invention is further configured such that first scrapers are symmetrically installed at the bottom end of the movable ring, and the two sets of first scrapers are movably connected to the inner wall of the tank.

[0025] Preferably, the movable ring rotates, driving the two sets of first scrapers to rotate, and the two sets of first scrapers clean the inner wall of the tank.

[0026] The present invention is further configured such that a second scraper is installed between the two sets of the first scraper, and the second scraper is movably connected to the bottom outer wall of the multiple sets of bag bodies.

[0027] Preferably, the two sets of first scrapers rotate, driving the second scraper to rotate, and the second scraper cleans the bottom outer wall of the multiple sets of cloth bag bodies.

[0028] In summary, the present invention has the following main beneficial effects:

[0029] 1. This invention solves the problem of poor cleaning at the lower end of pulse bag filters by incorporating a movable disc, movable pipes, and jet nozzles. The drive motor starts, rotating a set of drive shafts connected by a synchronous belt. Both drive shafts rotate synchronously, and their outer walls are threaded to the inner wall of the movable disc. This causes the movable disc to move downwards, thereby moving multiple movable pipes and jet nozzles downwards, which in turn moves multiple limiting plates downwards. As the jet nozzles continue to move downwards, they enter the interior of multiple bag bodies, improving the cleaning effect of the airflow from the jet nozzles on the outer walls of the bag bodies and extending the service life of the dust collector bags.

[0030] 2. This invention further improves the cleaning effect of the filter bags by incorporating a movable ring, a first scraper, and a second scraper. Two sets of drive shafts rotate, with one set connected to the transmission shaft via a synchronous belt. The rotation of the transmission shaft drives the transmission gear to rotate, which meshes with a gear ring. The rotation of the gear ring, in turn, drives the movable ring to rotate, which in turn drives the two sets of first scrapers to rotate, and subsequently drives the second scraper to rotate. The two sets of first scrapers clean the inner wall of the tank, while the second scraper cleans the outer wall of the bottom of multiple filter bag bodies, further improving the cleaning effect on the outer wall of the filter bag body and extending the service life of the filter bag body.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] The embodiments of the present invention will now be described.

[0044] For a baghouse pulse dust collector with good dust removal efficiency, please refer to [link / reference]. Figure 1 - Figure 9 It includes a tank body 1, an installation chamber 4 and a movable plate 9. The installation chamber 4 is installed on the upper end of the tank body 1, and the movable plate 9 is movably installed inside the installation chamber 4.

[0045] The movable plate 9 has multiple sets of reserved holes 10, and each set of reserved holes 10 is equipped with a movable pipe 11. Each set of movable pipes 11 extends into the interior of the tank 1 and is equipped with a jet nozzle 13. A pulse air pump 5 is installed at the upper end of the installation chamber 4. A second air outlet pipe 6 is installed at the outlet of the pulse air pump 5, and one end of the second air outlet pipe 6 extends into the interior of the installation chamber 4. Multiple sets of cloth bag bodies 19 are installed inside the tank 1.

[0046] The upper end of the installation chamber 4 is equipped with a drive motor 7. Two sets of drive shafts 8 are movably installed inside the installation chamber 4. One set of drive shafts 8 is connected to the output end of the drive motor 7. The two sets of drive shafts 8 are connected by a synchronous belt. The outer walls of the two sets of drive shafts 8 are threaded to the inner wall of the movable disc 9.

[0047] Please see Figure 1 - Figure 2One end of the tank body 1 is equipped with an air inlet pipe 2, and the other end of the tank body 1 is equipped with a first air outlet pipe 3. The bottom of the tank body 1 is provided with a discharge port. Dust-laden gas enters the interior of the tank body 1 through the air inlet pipe 2, the filtered gas is discharged through the first air outlet pipe 3, and impurities are discharged through the discharge port.

[0048] Please see Figure 3 - Figure 8 The tank body 1 is equipped with an installation plate 16. Multiple sets of brackets 17 are installed on the inner wall of the installation plate 16, and multiple sets of cloth bag bodies 19 are fitted on the outer wall of the multiple sets of brackets 17. The multiple sets of brackets 17 support the multiple sets of cloth bag bodies 19 respectively.

[0049] Please see Figure 3 - Figure 5 Multiple sets of bearing seats 14 are installed on the outer wall of multiple sets of jet heads 13, and each bearing seat 14 has a torsion spring at one end. Each bearing seat 14 has a movable rod 15 installed inside, and the bearings inside the bearing seats 14 limit the movement of the movable rods 15.

[0050] Please see Figure 3 - Figure 5 Multiple sets of movable rods 15 are movably connected at one end to the upper outer wall of multiple sets of brackets 17 and the inner wall of multiple sets of bag bodies 19. The outer walls of multiple sets of movable rods 15 are provided with rubber protective layers. Before entering the multiple sets of bag bodies 19, the multiple sets of movable rods 15 are inclined downwards. The lower ends of the multiple sets of movable rods 15 contact the upper ends of multiple sets of brackets 17, causing the multiple sets of movable rods 15 to tilt upwards. Then, the multiple sets of movable rods 15 enter the multiple sets of bag bodies 19 and fit against the inner walls of the multiple sets of bag bodies 19. At the same time, the filtered airflow enters the bag body 19 and creates a certain impact on the movable rods 15, causing the movable rods 15 to tilt towards the movable tube 11. At this time, the torsion spring at one end of the bearing drives the bearing to reset and rotate, thereby causing the movable rods 15 to knock against the inner wall of the bag body 19, assisting the removal of impurities remaining on the outer wall of the bag body 19. The rubber protective layer also protects the inner walls of the multiple sets of bag bodies 19.

[0051] Please see Figure 5 - Figure 8 Multiple sets of movable tubes 11 are symmetrically equipped with limit plates 12 on the outer wall of one end, and multiple sets of brackets 17 are symmetrically opened with limit grooves 18 on the inner wall. The outer walls of multiple sets of limit plates 12 are movably connected to the inner walls of multiple sets of limit grooves 18, and the multiple sets of limit plates 12 enter the multiple sets of limit grooves 18 respectively, which improves the stability of one end of the movable tube 11.

[0052] Please see Figure 3 - Figure 9A drive shaft 20 is movably installed inside the tank body 1, and one end of the drive shaft 20 extends into the inner wall of the tank body 1 and is connected to a set of drive shafts 8 by a synchronous belt. The two sets of drive shafts 8 rotate, and one set of drive shafts 8 is connected to the drive shaft 20 by a synchronous belt, so that the drive shaft 20 rotates.

[0053] Please see Figure 3 - Figure 9 The drive shaft 20 extends into the inner wall of the mounting plate 16 and a drive gear 21 is installed at one end. A movable ring 22 is movably installed at the bottom of the mounting plate 16. A toothed ring 23 is installed on the inner wall of the movable ring 22 and meshes with the drive gear 21. When the drive shaft 20 rotates, it drives the drive gear 21 to rotate. The drive gear 21 meshes with the toothed ring 23, and the toothed ring 23 rotates, thereby driving the movable ring 22 to rotate.

[0054] Please see Figure 3 - Figure 9 The bottom of the movable ring 22 is symmetrically equipped with first scrapers 24, and the two sets of first scrapers 24 are movably connected to the inner wall of the tank 1. When the movable ring 22 rotates, it drives the two sets of first scrapers 24 to rotate, and the two sets of first scrapers 24 clean the inner wall of the tank 1.

[0055] Please see Figure 3 - Figure 9 A second scraper 25 is installed between the two sets of first scrapers 24, and the second scraper 25 is movably connected to the bottom outer wall of the multiple sets of bag bodies 19. When the two sets of first scrapers 24 rotate, they drive the second scraper 25 to rotate, and the second scraper 25 cleans the bottom outer wall of the multiple sets of bag bodies 19.

[0056] The working principle of this invention is as follows: when the staff uses the bag pulse dust collector to filter dust-laden gas, the dust-laden gas enters the tank 1 through the inlet pipe 2, is filtered through multiple sets of filter bag bodies 19, and then the gas is discharged through the first outlet pipe 3.

[0057] After the bag pulse dust collector filters the dust-laden gas for a certain period of time, the pulse air pump 5 and the drive motor 7 are started. The pulse air pump 5 conducts the airflow through the first air outlet pipe 3 to the inside of the installation chamber 4. Then the airflow enters the multiple sets of movable pipes 11, and the multiple sets of movable pipes 11 spray the airflow out from the jet head 13.

[0058] When the drive motor 7 starts, it drives a set of drive shafts 8 to rotate. The two sets of drive shafts 8 are connected by a synchronous belt and rotate synchronously. The outer walls of the two sets of drive shafts 8 are threaded to the inner wall of the movable disk 9. Therefore, the movable disk 9 moves downward, thereby driving multiple sets of movable pipes 11 and multiple sets of jet nozzles 13 to move downward, which in turn drives multiple sets of limit plates 12 to move downward. After the multiple sets of jet nozzles 13 continue to move downward, they enter the interior of multiple sets of brackets 17, which improves the cleaning effect of the airflow sprayed by the multiple sets of jet nozzles 13 on the outer wall of multiple sets of cloth bag bodies 19.

[0059] As multiple sets of jet nozzles 13 continuously enter the interior of multiple sets of bag bodies 19, multiple sets of movable rods 15, before entering the interior of the multiple sets of bag bodies 19, are in a downward-sloping state. The lower ends of the multiple sets of movable rods 15 contact the upper ends of the multiple sets of supports 17, causing the multiple sets of movable rods 15 to tilt upwards. Then, the multiple sets of movable rods 15 enter the interior of the multiple sets of bag bodies 19, and the multiple sets of movable rods 15 respectively adhere to the inner wall of the multiple sets of bag bodies 19. At the same time, the filtered airflow enters the bag body 19, forming a certain pressure on the movable rods 15. The impact causes the movable rod 15 to tilt towards the movable tube 11. Each of the multiple sets of bearings 14 has a torsion spring at one end. At this time, the torsion spring at one end of the bearing drives the bearing to rotate back to its original position, thereby causing the movable rod 15 to strike the inner wall of the bag body 19. The multiple sets of movable rods 15 strike the inner walls of the multiple sets of bag bodies 19, helping the impurities remaining on the outer wall of the bag body 19 to fall off. The multiple sets of limiting plates 12 enter the multiple sets of limiting grooves 18 respectively, improving the stability of one end of the movable tube 11.

[0060] When the two sets of drive shafts 8 rotate, one set of drive shafts 8 is connected to the transmission shaft 20 via a synchronous belt. The rotation of the transmission shaft 20 drives the transmission gear 21 to rotate. The transmission gear 21 meshes with the gear ring 23. The rotation of the gear ring 23 drives the movable ring 22 to rotate, which in turn drives the two sets of first scrapers 24 to rotate, and then drives the second scraper 25 to rotate. The two sets of first scrapers 24 clean the inner wall of the tank 1, while the second scraper 25 cleans the outer wall of the bottom of multiple sets of bag bodies 19, further improving the cleaning effect of the outer wall of the bag body 19 and extending the service life of the bag body 19.

[0061] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
