Description

Technical Field

[0001] This invention relates to the field of dust filtration technology, and more particularly to a dust collection device for a ball mill used in ceramic tile production. Background Technology

[0002] Dust removal in ball mills is generally achieved using cyclone dust collectors and baghouse dust collectors. Due to their lower maintenance and operating costs, baghouse dust collectors are the preferred choice for most tile manufacturers. To maximize the filtration area and reduce filtration velocity within a limited space, the filter bags are typically designed with a pleated (folded) structure, significantly increasing the filter media area within the same volume and thus improving dust removal efficiency. However, the pleated shape also leads to dust accumulation in the folds and grooves, creating difficult-to-remove "dust dead zones." Over time, this increases resistance and affects system stability.

[0003] Existing baghouse dust collectors mostly use overall pulse jet cleaning or mechanical vibration for dust removal, but these methods generally have the following drawbacks: First, the back-blowing airflow acts on all pleats simultaneously, making it impossible to perform targeted and timed deep cleaning of each pleat. This results in uneven dust removal, stubborn local dust accumulation, and frequent overall cleaning, which can easily lead to excessive wear of the filter media. Second, the dust removal process often requires stopping the machine or switching filter units, making continuous online operation impossible and reducing equipment utilization. Third, during back-blowing, the pleats are in a naturally folded state, making it difficult for the high-pressure pulse airflow to vertically impact the deep layers of the filter media. This results in incomplete removal of hardened dust and a significant reduction in the dust removal effect. Summary of the Invention

[0007] Preferably, the end of the limiting shaft away from the filter chamber is fixedly connected to the side of the transmission chamber two away from the filter chamber, the front end of the second spring is fixedly connected to the front end of the L-shaped drive frame, and the front end of the first spring is fixedly connected to the middle of the connecting frame.

[0008] Preferably, the lower end of the drive shaft four is rotatably connected to the bottom wall of the transmission chamber one near the filter chamber, and the upper end of the gear two is rotatably connected to the top wall of the drive chamber away from the filter chamber.

[0009] Preferably, the upper end of the single-tooth gear one is rotatably connected to the top wall of the transmission chamber two on the side away from the filter chamber, and the lower end of the single-tooth gear two is rotatably connected to the bottom wall of the transmission chamber two on the side away from the filter chamber.

[0010] Preferably, the upper end of the double-layer indexing plate is rotatably connected to the top wall of the transmission chamber two near the filter chamber, and the lower end of the double-layer indexing plate is rotatably connected to the bottom wall of the transmission chamber two near the filter chamber.

[0011] Preferably, a connecting shaft is slidably connected to the side of the regulating chamber near the filter chamber.

[0013] The dust collection device for ball mills used in ceramic tile production provided by this invention has the following advantages: 1. By using a nozzle on one side of the connecting pipe to pulse-type blow and control the gradual rotation of the inner pleats of the bag filter, the filter can be cleaned while filtering. At the same time, as the bag filter rotates by an angle of one pleat, the single teeth of the first and second single-tooth gears will rotate one revolution before engaging with the double-layer indexing plate one by one. This allows all nozzles sufficient time to backflush a pleat, significantly increasing the cleaning depth of the pleat and effectively removing deep-seated ash. During the rotation process, each pleat receives targeted strong blowing in turn, avoiding excessive wear in certain areas while maintaining normal filtration in other areas, thus achieving online cleaning without stopping the machine.

[0014] 2. During the pulse cleaning process, the wedge-shaped top block can open up the pleats of the bag filter, thereby expanding the folds and eliminating dead corners where dust accumulates. This allows the high-pressure pulse airflow to vertically impact the deep layers of the filter media, stripping away hardened dust and ensuring thorough cleaning. Before the bag filter rotates, the wedge-shaped top block disengages first to avoid mechanical scraping and damage to the filter cloth, reducing frictional resistance and wear. The combination of these two features achieves powerful yet non-destructive cleaning, balancing cleaning effectiveness and bag durability. Attached Figure Description

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] like Figures 1-6 As shown, this embodiment proposes a dust collection device for a ball mill used in ceramic tile production, including a bracket 11. A filter chamber 12 is fixedly connected to the upper end of the bracket 11. An air inlet 13 is fixedly connected to one side of the filter chamber 12. An air outlet 14 is fixedly connected to the upper end of the filter chamber 12. An adjustment chamber 15 is fixedly connected to the side of the filter chamber 12 away from the air inlet 13. A transmission chamber 16 is fixedly connected to the upper end of the adjustment chamber 15. A transmission chamber 2 17 is fixedly connected to the upper end of the transmission chamber 16. A drive chamber 18 is fixedly connected to the upper end of the transmission chamber 2 17. A bag filter 19 is rotatably connected inside the filter chamber 12. Specifically, the end of the air inlet 13 of the dust collection device away from the filter chamber 12 is connected to the exhaust pipe of the ball mill, and a dust collection box is installed on the lower end of the filter chamber 12. The dust collector of the ball mill is started, and the dust from grinding the ball mill is sent into the interior of the filter chamber 12 through the air inlet 13. The dust-laden air is filtered by the bag filter 19 and discharged from the upper air outlet 14. Some of the dust falls into the dust collection box, and some of the dust remains on the outside of the bag filter 19.

[0020] In this embodiment, a blower chamber 22 is fixedly connected to the bottom wall of the drive chamber 18 near the bag filter 19. A drive shaft 23 is rotatably connected to the middle of the blower chamber 22. An impeller 24 is fixedly connected to the middle of the drive shaft 23. A baffle 25 is fixedly connected to the end of each blade of the impeller 24 away from the drive shaft 23. A connecting pipe 26 is connected to the end of the blower chamber 22 near the bag filter 19. Nozzles 27 are evenly distributed on the side of the connecting pipe 26 near the regulating chamber 15. The spray direction of the nozzles 27 is towards the inner wall of the bag filter 19. A motor 21 is fixedly connected to the upper end of the drive chamber 18. The driving end of the lower end of the motor 21 is fixedly connected to the upper end of the drive shaft 23.

[0021] In this embodiment, the end of the air inlet 13 away from the filter chamber 12 is provided with a flange interface for connecting the ball mill exhaust pipe. The interior of the nozzle 27 is connected to the interior of the connecting pipe 26. The side of the baffle 25 away from the drive shaft 23 is slidably engaged with the side wall of the air chamber 22.

[0022] Specifically, the motor 21 is started, and the impeller 24 and baffle 25 are driven to rotate inside the air chamber 22 via the drive shaft 23. This causes the airflow to be sprayed into the bag filter 19 through the connecting pipe 26 and the nozzle 27. The airflow backflows from the inside of the bag filter 19 into the bag pleats, blowing away the dust remaining in the bag pleats. When one baffle 25 rotates to the port of the air chamber 22 connected to the connecting pipe 26, the airflow to the connecting pipe 26 stops, and the nozzle 27 stops blowing air into the bag filter 19. When one of the baffles 25 is rotated away, the airflow re-enters the connecting pipe 26, and the nozzle 27 blows air into the bag filter 19 again. This process is repeated alternately to achieve intermittent pulse blowing, which causes the bag pleats of the bag filter 19 to vibrate while being blown from the inside, which is beneficial for dust removal.

[0023] In this embodiment, a full gear 31 is fixedly connected to the upper end of drive shaft 23, and a full gear 32 is meshed with the full gear 31. Drive shaft 33 is fixedly connected to the middle of full gear 32. A single-tooth gear 34 is fixedly connected to the lower end of drive shaft 33. A bevel gear 35 is fixedly connected to the lower end of single-tooth gear 34. Bevel gear 36 is meshed with bevel gear 36. A limit shaft 37 is rotatably connected to the middle of bevel gear 36. Bevel gear 36 is also meshed with bevel gear 38. A single-tooth gear 310 is fixedly connected to the lower end of bevel gear 38. Drive shaft 39 is fixedly connected to the middle of single-tooth gear 310. The drive housing 18 is located near... A drive shaft 311 is rotatably connected to one side of the filter chamber 12. A double-layer indexing plate 312 is fixedly connected to the outer side of the drive shaft 311. An L-shaped drive frame 316 is fixedly connected to the lower end of the drive shaft 311. A connecting frame 319 is fixedly connected to the rear end of the L-shaped drive frame 316. A pawl 314 is rotatably connected to the middle of the L-shaped drive frame 316. A spring 318 is fixedly connected to the front end of the pawl 314. A pawl 313 is rotatably connected to the rear end of the connecting frame 319. A spring 317 is fixedly connected to the front end of the pawl 313. A ratchet 315 is fixedly connected to the upper end of the bag filter 19. Pawls 313 and 314 are both engaged with the ratchet 315. The teeth of the single-tooth gear 34 and the single-tooth gear 310 respectively mesh alternately with the upper and lower indexing slots of the double-layer indexing plate 312, causing the double-layer indexing plate 312 to swing back and forth. Through the pawl 313 and the pawl 314, the ratchet 315 drives the bag filter 19 to rotate intermittently, so that each pleat of the bag filter 19 is aligned with the nozzle 27 in sequence.

[0024] In this embodiment, the end of the limiting shaft 37 away from the filter chamber 12 is fixedly connected to the side of the transmission chamber 2 17 away from the filter chamber 12, the front end of the second spring 318 is fixedly connected to the front end of the L-shaped drive frame 316, and the front end of the first spring 317 is fixedly connected to the middle of the connecting frame 319.

[0025] In this embodiment, the lower end of the drive shaft 311 is rotatably connected to the bottom wall of the transmission chamber 16 near the filter chamber 12, and the upper end of the gear 32 is rotatably connected to the top wall of the drive chamber 18 away from the filter chamber 12.

[0026] In this embodiment, the upper end of the single-tooth gear 34 is rotatably connected to the top wall of the transmission chamber 17 away from the filter chamber 12, and the lower end of the single-tooth gear 310 is rotatably connected to the bottom wall of the transmission chamber 17 away from the filter chamber 12.

[0027] In this embodiment, the upper end of the double-layer indexing plate 312 is rotatably connected to the top wall of the transmission chamber 2 17 near the filter chamber 12, and the lower end of the double-layer indexing plate 312 is rotatably connected to the bottom wall of the transmission chamber 2 17 near the filter chamber 12. The number of teeth of the ratchet 315 is the same as the number of inner pleats of the bag filter 19.

[0028] Specifically, drive shaft 23 drives gear 32 to rotate via gear 31, which in turn drives single-tooth gear 34 to rotate via drive shaft 33. This, in turn, drives single-tooth gear 310 to rotate in the opposite direction to single-tooth gear 34 via bevel gears 36 and 38. This causes single-tooth gears 34 and 310 to alternately mesh with the double-layer indexing plate 312. Specifically, the meshing of a single tooth of single-tooth gear 34 with the double-layer indexing plate 312 causes the double-layer indexing plate 312 to rotate by one tooth groove angle. Once single-tooth gear 34 disengages from the double-layer indexing plate 312, the single-tooth gear... The second gear 310 meshes with the double-layer indexing plate 312, causing the double-layer indexing plate 312 to rotate and reset, making the double-layer indexing plate 312 oscillate back and forth. This, in turn, drives the L-shaped drive frame 316 to oscillate back and forth around the drive shaft 311 via the drive shaft 311. Since the L-shaped drive frame 316 is connected to the connecting frame 319, the connecting frame 319 will also oscillate back and forth around the drive shaft 311. When the single-tooth gear 34 drives the double-layer indexing plate 312 to rotate, the pawl 313 and pawl 314 will push the ratchet 315 to rotate by one tooth groove angle. Due to the filter bag of the bag filter 19... The number of inner pleats is the same as the number of teeth on ratchet 315. At this time, the next pleat on the inner side of the bag filter 19 is rotated to the alignment position of the nozzle 27 outlet and then stops, allowing the nozzle 27 to continue blowing dust onto the next pleat of the bag filter 19. When the single-tooth gear 310 and the double-layer indexing plate 312 mesh, the cooperation of spring 318 and spring 317 causes pawl 313 and pawl 314 to enter the next tooth groove of ratchet 315 respectively. The nozzle 27 on one side of the connecting pipe 26 blows dust in a pulse manner and controls the bag of the bag filter 19. The inner pleats rotate and clean the dust gradually, thus achieving the effect of filtering and cleaning at the same time. At the same time, after the bag filter 19 rotates by the angle of one pleat, the single teeth of the single tooth gear 34 and the single tooth gear 310 will rotate one revolution and then mesh with the double-layer indexing plate 312 one by one. This allows all the nozzles 27 to have enough time to backwash a pleat, greatly increasing the cleaning depth of the pleat and effectively removing deep dust. At the same time, the rotation process allows each pleat to receive fixed-point strong blowing in turn, avoiding excessive wear in some areas, while maintaining normal filtration in other areas, achieving online dust cleaning without stopping the machine.

[0029] In this embodiment, a connecting shaft 41 is slidably connected to the side of the regulating chamber 15 near the filter chamber 12. A top shaft 42 is fixedly connected to both the upper and lower ends of the connecting shaft 41. The end of the top shaft 42 near the bag filter 19 passes through the side of the filter chamber 12 away from the air inlet 13 and is fixedly connected to a wedge-shaped top block 43. Springs 34 are evenly distributed on the side of the connecting shaft 41 near the filter chamber 12. A drive shaft 55 is fixedly connected to the side of the connecting shaft 41 away from the filter chamber 12. A rotating ball 46 is rotatably connected to the side of the drive shaft 55 away from the connecting shaft 41. A concave wheel 47 is fixedly connected to the lower end of the drive shaft 39. The side of the concave wheel 47 slides in cooperation with the rotating ball 46.

[0030] In this embodiment, the ends of the springs 44 away from the connecting shaft 41 are fixedly connected to the side of the filter chamber 12 away from the air inlet 13, and the lower end of the concave wheel 47 is rotatably connected to the bottom wall of the regulating chamber 15 away from the filter chamber 12.

[0031] Specifically, when the single-tooth gear 310 rotates, it simultaneously drives the concave wheel 47 to rotate via the drive shaft 39. When the pawls 313 and 314 drive the ratchet 315 to adjust the angle, the concave part of the concave wheel 47 rotates and comes into contact with the rotating ball 46. At this time, the spring 44 drives the connecting shaft 41 to reset, thereby causing the wedge-shaped top block 43 to be pulled out from the outer fold of the bag via the top shaft 42. When switching to the next fold of the bag for cleaning, the rotation of the concave wheel 47 causes the rotating ball 46 to slide out from the concave part of the concave wheel 47, allowing the wedge-shaped top block 43 to return to its original position. The wedge-shaped top block 43 is inserted into the pleats of the bag filter 19, opening up the pleats of the bag being cleaned. During pulse cleaning by the nozzle 27, the wedge-shaped top block 43 can open up the pleats of the bag filter 19, thereby expanding the folded areas, eliminating dead corners of dust accumulation, and allowing the high-pressure pulse airflow to vertically impact the deep layers of the filter material, peeling off hardened dust, and achieving thorough cleaning. Before the bag filter 19 rotates, the wedge-shaped top block 43 disengages first to avoid mechanical scraping and damage to the filter cloth, reducing frictional resistance and wear. The two work together to achieve powerful and non-destructive cleaning, balancing cleaning effect and bag durability.

[0032] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
