Description

Technical Field

[0001] The invention relates to the field of industrial dust removal, and in particular to a dust removal device used in paint production. Background Art

[0002] During the coating production process, a large amount of dust and particles will be generated due to the processing, mixing, grinding and packaging of raw materials. These fine particles will not only pollute the environment, but also may cause harm to the health of workers, such as respiratory diseases. Therefore, it is necessary to use dust removal devices to capture and remove these dusts, which not only helps to protect the environment and employee health, but also improves production efficiency and product quality.

[0003] The Chinese patent with publication number "CN115739395A" discloses a dust removal device, including a shell, the side wall of the shell is provided with an air inlet, and the two ends of the shell are respectively provided with an air outlet and a dust outlet. A dust collecting pipe and a static pressure box are provided inside the shell, and one end of the dust collecting pipe is provided at the dust outlet. The end with a larger diameter of the static pressure box is connected to the end of the shell close to the air outlet, and the end with a smaller diameter of the static pressure box is provided with an air inlet pipe, and the end of the air inlet pipe away from the static pressure box extends into the dust collecting pipe. A conical tube is provided between the static pressure box and the dust collecting tube, and the closed end of the conical tube is connected to the end with a smaller diameter of the static pressure box, and the expanded end of the conical tube extends in the direction close to the dust collecting tube;

[0004] Although the dust removal device increases the dust removal path of the gas without increasing the volume of the dust removal device, so that the gas and particulate matter are fully separated, and after the large particles are separated, the fine particles are separated, thereby improving the dust removal efficiency and dust removal effect, but when the filter device is blocked and needs to be replaced or cleaned, the device cannot continue the dust removal operation, so the dust removal operation is stopped, which is not conducive to continuous production and work efficiency.

[0018] The beneficial effects of the present invention are as follows:

[0019] By setting a batch cleaning structure, the scraper strips 1 and 2 in the batch cleaning structure are pressed against the outer wall and the inner wall of the filter cartridge respectively, and the bottom rod is rotated to drive the scraper strips 1 and 2 to rotate along the center of the bottom cover, so that the non-woven fabric used for filtering and adsorption of the filter cartridge is deformed, so that the adsorbed dust falls off, and the filter cartridge can be thoroughly cleaned, so that the filter cartridge can be recycled, and the service life of the filter cartridge is extended;

[0020] Since two cleaning structures are provided, two filter cartridges can be cleaned, and when one is being cleaned, the other can be cleaned normally, so that the dust removal operation is not interrupted and the operation is not stopped due to filter cartridge blockage and filter cartridge replacement.

[0021] By setting up a synchronous dust discharge structure, when the bottom rod rotates to clean dust, the threaded rod will be driven to rotate, so that the first guide cylinder slides upward, and the baffle is driven to move through the linkage of the first guide groove, the first guide block and the connecting ring, so that the baffle no longer blocks the dust discharge groove, so that the dust generated by cleaning can enter the dust cleaning cover through the dust discharge groove, and in the dust cleaning process, the synchronous dust discharge structure is only driven to operate once, so that the continuous rotation of the baffle and the squeezing of the bottom cover are avoided, and the dust discharge process is ensured to be smooth and stable;

[0022] The first guide tube rises until the first guide groove is separated from the first guide block. Since the angle between the top and the bottom of the first guide groove is 130 degrees, the angle of the first guide block and the connecting ring guided by the first guide groove is 130 degrees. Since the angles on both sides of the dust outlet groove are 120 degrees, the baffle can make the dust outlet groove in a fully open state after rotating 130 degrees through the connecting ring.

[0023] The bottom rod is driven to rotate by the two mutually meshing bevel gears of the connecting shaft and the cone, so that the batch cleaning structure and the synchronous dust discharge structure operate synchronously. At the same time, the rotation of the connecting shaft can also drive the two rotating plates to rotate synchronously but in the opposite direction through the linkage of the spur gear 2, the spur gear 3 and the threaded rod 2, so that the dust cleaned by the cleaning cover is discharged into the dust storage chamber, so that the cleaning operation of the filter cartridge, the discharge operation of the cleaned dust by the filter cartridge and the dust discharge operation of the cleaning cover can be carried out synchronously, thereby improving the dust discharge efficiency of the entire device;

[0024] When the second guide cylinder moves to the side of the spur gear three, the second guide groove separates from the second guide block. Since the angle between one end and the other end of the second guide groove is ninety degrees, the second guide block has rotated ninety degrees at this time, thereby driving the two rotating plates to rotate synchronously in the opposite direction by ninety degrees, so that the bottom of the cleaning cover is in a completely open state.

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] like Figure 1 - Fig.14 As shown, a dust removal device for coating production comprises a dust removal box 1, a top cover 2 is connected to the top of the dust removal box 1, two connection grooves 6 are provided on the top of the top cover 2 through the bottom, a shunt pipe 3 is fixedly connected to the top of the top cover 2 located at the top of the two connection grooves 6, an air extractor 4 is fixedly connected to the front of the dust removal box 1, a connecting hose 5 is fixedly connected between the air outlet end of the air extractor 4 and the front end of the shunt pipe 3, and two batch cleaning structures 7 are arranged inside the dust removal box 1;

[0042] The batch cleaning structure 7 includes a scraper strip 12 and a scraper strip 16. The interior of the dust removal box 1 is fixedly connected to a cleaning cover 11 at the bottom of the two connecting grooves 6 near the top. The bottom of the top cover 2 and the bottom of the two connecting grooves 6 are fixedly connected to a fixing ring 9. The bottom of the top cover 2 and the interior of the cleaning cover 11 are threadedly connected with a filter cartridge 10 through the fixing ring 9. The interior of the cleaning cover 11 and the bottom of the filter cartridge 10 are fixedly connected with a bottom cover 13. The bottom of the bottom cover 13 is rotatably connected to a bottom rod 14. The top of the bottom cover 13 and the interior of the filter cartridge 10 are rotatably connected to a top rod 15. The scraper strip 12 is fixedly connected to the top of the bottom rod 14 at one end, and the scraper strip 2 16 is fixedly connected to the top of the top rod 15 at one end.

[0043] Start the vacuum pump 4, and let the air with dust in the paint production environment enter the interior of the two cleaning hoods 11 along the connecting hose 5 and the diversion pipe 3, and then the two filter cartridges 10 absorb the air with dust. Due to the setting of the bottom cover 13, the air with dust can only be absorbed by the filter cartridges 10 when it is blown into the cleaning hood 11, and will not fall along the bottom of the cleaning hood 11.

[0044] Since a large amount of air with dust attached will be generated during the paint production process, the filter cartridge 10 will be blocked after absorbing a large amount of air with dust attached, resulting in the inability to perform dust removal operations. If the filter cartridge 10 is replaced, the dust removal operation will be stopped. Therefore, through two batch cleaning structures 7, the two filter cartridges 10 can be cleaned so that the filter cartridges 10 can still perform dust removal operations. Moreover, when one of the batch cleaning structures 7 is running, the other batch cleaning structure 7 stops running. Therefore, when one of the filter cartridges 10 is performing a cleaning operation, the other filter cartridge 10 can still perform dust removal operations normally, so that the dust removal operation will not be interrupted.

[0045] The specific operating steps of the batch cleaning structure 7 are: rotating the bottom rod 14, driving the top rod 15 to rotate together, and then driving the scraper bar 12 and the scraper bar 2 16 to rotate along the center of the bottom cover 13. Since the scraper bar 12 and the scraper bar 2 16 are respectively squeezed with the outer wall and the inner wall of the filter cartridge 10, during the rotation of the scraper bar 12 and the scraper bar 2 16, the non-woven fabric used for filtering and adsorption of the filter cartridge 10 will be deformed, and the air adsorbed with dust will fall off. This cycle is repeated to complete the thorough cleaning of the filter cartridge 10.

[0046] In this embodiment, the first scraper bar 12 is pressed against the outer wall of the filter cartridge 10 , and the second scraper bar 16 is pressed against the inner wall of the filter cartridge 10 .

[0047] In this embodiment, the connecting groove 6 is communicated with the interior of the filter cartridge 10 , and a dust storage chamber 8 is fixedly connected to the bottom of the dust removal box 1 .

[0048] In this embodiment, a synchronous dust discharge structure 17 is provided at the bottom of the bottom cover 13, and the synchronous dust discharge structure 17 includes a baffle 18. A dust discharge groove 19 is provided at the top of the bottom cover 13, a placement groove 20 is provided inside the bottom cover 13, and the baffle 18 is located inside the placement groove 20. A linkage block 21 is fixedly connected to the side of the baffle 18 and located inside the placement groove 20. An arc groove 22 is provided inside the placement groove 20 at the bottom of the bottom cover 13, and a linkage rod 23 is fixedly connected to the bottom of the linkage block 21 through the arc groove 22. A through groove is provided at the center position of the top circle of the bottom cover 13 through the bottom, and a threaded rod 24 is fixedly connected between the top rod 15 and the bottom rod 14 and through the through groove. A first guide cylinder 25 is threadedly connected to the outer surface of the threaded rod 24, and a spiral first guide groove 26 is provided on the outer surface of the first guide cylinder 25. A first guide block 27 is slidably connected to the inside of the first guide groove 26 near the top, and a connecting ring 28 is fixedly connected to one end of the linkage rod 23 and located at the top of the bottom rod 14 near the other end.

[0049] The specific steps of the synchronous dust discharge structure 17 are as follows: the bottom rod 14 rotates, and while the batch cleaning structure 7 performs dust cleaning operation on the filter cartridge 10, the bottom rod 14 drives the threaded rod 1 24 to rotate, thereby driving the first guide cylinder 25 to slide only upwards. Since the first guide groove 26 is spiral, during the upward movement of the first guide cylinder 25, the first guide block 27 and the connecting ring 28 are driven to rotate along the first guide groove 26. Therefore, the rotation of the connecting ring 28 drives the linkage rod 23 to rotate, thereby driving the linkage block 21 to move along the arc groove 22, pulling the baffle 18 to move along the placement groove 20, so that the baffle 18 no longer blocks the dust discharge groove 19. Therefore, when the batch cleaning structure 7 cleans the dust adsorbed by the filter cartridge 10, the dust can enter the interior of the cleaning cover 11 through the dust discharge groove 19;

[0050] When the first guide tube 25 continues to move upward through the threaded rod 1 24 until the bottom of the first guide tube 25 contacts the bottom of the top rod 15, the first guide tube 25 cannot move upward any further. At this time, the first guide block 27 is no longer located in the first guide groove 26, so that when the bottom rod 14 and the top rod 15 rotate and drive the threaded rod 1 24 to rotate, the first guide tube 25 will be driven to rotate together, and the connecting ring 28 cannot be driven to rotate at this time, so the baffle 18 no longer rotates. Therefore, when the batch cleaning structure 7 is running, the synchronous dust discharge structure 17 will be driven to run, and during the continuous operation of the batch cleaning structure 7, the synchronous dust discharge structure 17 is only driven to run once synchronously, so as to avoid the continuous movement of the batch cleaning structure 7, which drives the continuous rotation of the baffle 18, causing the baffle 18 and the bottom cover 13 to be squeezed.

[0051] When the cleaning operation of the filter cartridge 10 is completed, the reverse bottom rod 14 drives the threaded rod 24 to reverse, which can drive the first guide tube 25 to move downward, so that the first guide block 27 is re-located inside the first guide groove 26, and then the baffle 18 can be driven to reverse through the connecting ring 28 until the baffle 18 blocks the dust outlet groove 19 again. At this time, the rotation of the bottom rod 14 can be stopped, and the first guide tube 25 can be fixed through the self-locking ability of the threaded rod 24, and then the first guide block 27 and the connecting ring 28 are fixed together. Therefore, the baffle 18 can be automatically fixed after blocking the dust outlet groove 19.

[0052] In this embodiment, the inner wall of the connecting ring 28 is fixedly connected to the first guide block 27 , and the connecting ring 28 is rotatably connected to the bottom of the bottom cover 13 .

[0053] In this embodiment, the diameter of the first guide cylinder 25 is consistent with the diameter of the through groove, the surface area of ​​the baffle 18 is larger than the surface area of ​​the dust outlet groove 19, the angles on both sides of the dust outlet groove 19 are one hundred and twenty degrees, and the difference between the angle between the top of the first guide groove 26 and the center of the first guide cylinder 25 and the angle between the bottom of the first guide groove 26 and the center of the first guide cylinder 25 is one hundred and thirty degrees.

[0054] The first guide cylinder 25 rises until the first guide groove 26 is separated from the first guide block 27. Since the angle between the top and the bottom of the first guide groove 26 is one hundred and thirty degrees, the angle of rotation of the first guide block 27 together with the connecting ring 28 guided by the first guide groove 26 is one hundred and thirty degrees. Since the angles on both sides of the dust outlet groove 19 are one hundred and twenty degrees, the baffle 18 can make the dust outlet groove 19 in a fully open state after rotating one hundred thirty degrees through the connecting ring 28.

[0055] In this embodiment, two pairs of fixed blocks 29 are symmetrically fixedly connected to the bottom of the dust storage chamber 8, and a discharge plate 30 is rotatably connected between each pair of fixed blocks 29, and a buckle is connected between the discharge plate 30 and the dust storage chamber 8;

[0056] When it is necessary to collect the dust processed by the dust removal chamber 8, it is only necessary to open the buckle and rotate the discharge plate 30 to open the bottom of the dust storage chamber 8, so that the dust can be discharged centrally through the dust inside the dust storage chamber 8.

[0057] In this embodiment, motors 31 are fixedly connected to both sides of the dust removal box 1, and a connecting shaft 32 is rotatably connected to the inner wall of the dust removal box 1 through the interior of the cleaning cover 11. The output shaft of the motor 31 is fixedly connected to one end of the connecting shaft 32, and the other end of the connecting shaft 32 and the bottom of the bottom rod 14 are fixedly connected to a bevel gear 33 at the other end, and the two bevel gears 33 are meshed with each other.

[0058] The motor 31 is started to drive the connecting shaft 32 to rotate, and through two mutually meshing bevel gears 33, the bottom rod 14 is driven to rotate together, and then the threaded rod 24 and the top rod 15 are driven to rotate synchronously, so that the batch cleaning structure 7 and the synchronous dust removal structure 17 operate synchronously.

[0059] In this embodiment, two pairs of connecting blocks 35 are fixedly connected at the bottom center position of the dust cleaning cover 11 and are symmetrically connected front and back, and a rotating plate 34 is rotatably connected between each pair of connecting blocks 35. The sides of the two connecting blocks 35 on one side are rotatably connected to a spur gear 1 36. The outer surface of the connecting shaft 32 and the side of the dust cleaning cover 11 are fixedly connected to a spur gear 2 38. The side of the spur gear 1 36 at the rear is rotatably connected to the inner wall of the dust removal box 1. A threaded rod 2 40 is rotatably connected, and a spur gear 39 is fixedly connected to the outer surface of the threaded rod 2 40 at one end. A connecting tube 37 is fixedly connected to the side of the spur gear 1 36 at the rear and the outer surface of the threaded rod 2 40. The outer surface of the threaded rod 2 40 and the inner surface of the connecting tube 37 are threadedly connected to a second guide tube 41. The outer surface of the second guide tube 41 is provided with a second spiral guide groove 42. The second guide block 43 is slidably connected to the inside of the second guide groove 42. The second guide block 43 is fixedly connected to the inner wall of the connecting tube 37.

[0060] When the connecting shaft 32 rotates synchronously, it drives the spur gear 2 38 to rotate, and then drives the spur gear 3 39 to rotate synchronously, thereby driving the threaded rod 2 40 to rotate synchronously, so that the second guide cylinder 41 slides toward one end along the inside of the connecting cylinder 37, and then through the guidance of the second guide groove 42, drives the second guide block 43 to rotate clockwise together with the connecting cylinder 37. The clockwise rotation of the connecting cylinder 37 can drive the spur gear 1 36 at the rear to rotate together, and then drives the spur gear 1 36 at the front that is meshed with it. The two spur gears 36 rotate at the same time, and the rotation directions of the two spur gears 36 are opposite, so the two rotating plates 34 are driven to rotate synchronously but in opposite directions, so that the dust cleaned by the cleaning cover 11 can be discharged into the dust storage chamber 8. Moreover, since it is the connecting shaft 32 that rotates, the rotating plate 34 is driven to rotate, and the rotation of the connecting shaft 32 will drive the batch cleaning structure 7 and the synchronous dust discharge structure 17 to operate together. Therefore, the cleaning operation of the filter cartridge 10, the discharge operation of the cleaned dust by the filter cartridge 10, and the dust discharge operation of the cleaning cover 11 can be carried out synchronously.

[0061] In this embodiment, the difference between the angle between one end of the second guide groove 42 and the center of the second guide cylinder 41 and the angle between the other end of the second guide groove 42 and the center of the second guide cylinder 41 is ninety degrees, the spur gear 2 38 and the spur gear 3 39 are meshed with each other, and the side surface of the rotating plate 34 passes through the side surface of the connecting block 35 and is fixedly connected to the spur gear 1 36;

[0062] When the second guide cylinder 41 moves to the side of the spur gear three 39, the second guide groove 42 is separated from the second guide block 43. Since the angle between one end and the other end of the second guide groove 42 is ninety degrees, the second guide block 43 has rotated ninety degrees at this time, thereby driving the two rotating plates 34 to rotate synchronously in the opposite direction by ninety degrees, so that the bottom of the cleaning cover 11 is in a fully open state.

[0063] It should be noted that the present invention is a dust removal device for paint production. When in use, the air extractor 4 is started to draw the air with dust in the paint production environment into the interior of the two dust cleaning covers 11 along the connecting hose 5 and the diverter pipe 3, and then the two filter cartridges 10 adsorb the air with dust. Due to the arrangement of the bottom cover 13, the air with dust can only be adsorbed by the filter cartridges 10 when it is blown into the interior of the dust cleaning cover 11, and will not fall along the bottom of the dust cleaning cover 11.

[0064] The motor 31 is started to drive the connecting shaft 32 to rotate, and through the two mutually meshing bevel gears 33, the bottom rod 14 is driven to rotate together, and then the threaded rod 1 24 and the top rod 15 are driven to rotate synchronously, so that the batch cleaning structure 7 and the synchronous dust discharge structure 17 operate synchronously;

[0065] The specific operation steps of the batch cleaning structure 7 are as follows: the bottom rod 14 is rotated to drive the top rod 15 to rotate together, and then the scraper strip 12 and the scraper strip 2 16 are driven to rotate along the center of the bottom cover 13. Since the scraper strip 12 and the scraper strip 2 16 are respectively pressed against the outer wall and the inner wall of the filter cartridge 10, the non-woven fabric used for filtering and adsorption of the filter cartridge 10 will be deformed during the rotation of the scraper strip 12 and the scraper strip 2 16, and the air adsorbed with dust will fall off. This cycle is repeated to completely clean the filter cartridge 10.

[0066] The specific steps of the synchronous dust discharge structure 17 are as follows: the bottom rod 14 rotates, and while the batch cleaning structure 7 performs dust cleaning operation on the filter cartridge 10, the bottom rod 14 drives the threaded rod 1 24 to rotate, thereby driving the first guide cylinder 25 to slide only upwards. Since the first guide groove 26 is spiral, during the upward movement of the first guide cylinder 25, the first guide block 27 and the connecting ring 28 are driven to rotate along the first guide groove 26. Therefore, the rotation of the connecting ring 28 drives the linkage rod 23 to rotate, thereby driving the linkage block 21 to move along the arc groove 22, pulling the baffle 18 to move along the placement groove 20, so that the baffle 18 no longer blocks the dust discharge groove 19. Therefore, when the batch cleaning structure 7 cleans the dust adsorbed by the filter cartridge 10, the dust can enter the interior of the cleaning cover 11 through the dust discharge groove 19;

[0067] When the first guide tube 25 continues to move upward through the threaded rod 1 24 until the bottom of the first guide tube 25 contacts the bottom of the top rod 15, the first guide tube 25 cannot move upward any further. At this time, the first guide block 27 is no longer located inside the first guide groove 26, so that the bottom rod 14 and the top rod 15 rotate, and when the threaded rod 1 24 rotates, the first guide tube 25 is driven to rotate together, and the connecting ring 28 cannot be driven to rotate at this time, so the baffle 18 no longer rotates. Therefore, when the batch cleaning structure 7 is running, the synchronous dust discharge structure 17 is driven to run, and during the continuous operation of the batch cleaning structure 7, the synchronous dust discharge structure 17 is only driven to run once synchronously, so as to avoid the continuous movement of the batch cleaning structure 7, which drives the continuous rotation of the baffle 18, so that the baffle 18 and the bottom cover 13 are squeezed.

[0068] When the dust cleaning operation of the filter cartridge 10 is completed, the reverse bottom rod 14 drives the threaded rod 1 24 to reverse, and the first guide cylinder 25 can be driven to move downward, so that the first guide block 27 is located inside the first guide groove 26 again, and then the baffle 18 can be driven to reverse through the connecting ring 28 until the baffle 18 blocks the dust outlet groove 19 again. At this time, the rotation of the bottom rod 14 can be stopped, and the first guide cylinder 25 can be fixed by the thread self-locking ability of the threaded rod 1 24, and then the first guide block 27 and the connecting ring 28 can be fixed together, so the baffle 18 can be automatically fixed after blocking the dust outlet groove 19;

[0069] When it is necessary to collect the dust processed by the dust removal chamber 8, it is only necessary to open the buckle and rotate the discharge plate 30 to open the bottom of the dust storage chamber 8, so that the dust can be discharged centrally through the dust inside the dust storage chamber 8;

[0070] When the connecting shaft 32 rotates synchronously, it drives the spur gear 2 38 to rotate, and then drives the spur gear 3 39 to rotate synchronously, thereby driving the threaded rod 2 40 to rotate synchronously, so that the second guide cylinder 41 slides toward one end along the inside of the connecting cylinder 37, and then through the guidance of the second guide groove 42, drives the second guide block 43 to rotate clockwise together with the connecting cylinder 37. The clockwise rotation of the connecting cylinder 37 can drive the spur gear 1 36 at the rear to rotate together, and then drives the spur gear 1 36 at the front that is meshed with it. The two spur gears 36 rotate at the same time, and the rotation directions of the two spur gears 36 are opposite, so the two rotating plates 34 are driven to rotate synchronously but in opposite directions, so that the dust cleaned by the cleaning cover 11 can be discharged into the dust storage chamber 8. Moreover, since it is the connecting shaft 32 that rotates, the rotating plate 34 is driven to rotate, and the rotation of the connecting shaft 32 will drive the batch cleaning structure 7 and the synchronous dust discharge structure 17 to operate together. Therefore, the cleaning operation of the filter cartridge 10, the discharge operation of the cleaned dust by the filter cartridge 10, and the dust discharge operation of the cleaning cover 11 can be carried out synchronously.
