Description

Technical Field

[0001] This invention relates to the field of tetrafluoroethylene dust removal technology, specifically to a dust removal device and method for finished tetrafluoroethylene products. Background Technology

[0002] Tetrafluoroethylene, also known as perfluoroethylene, is an organic compound with the chemical formula C2F4. It is a colorless gas at room temperature and pressure, insoluble in water, and is mainly used as a raw material for manufacturing new heat-resistant plastics, engineering plastics, new fire extinguishing agents, and fog suppressants. Tetrafluoroethylene is highly toxic and has carcinogenic effects.

[0003] Currently, during the production of tetrafluoroethylene (PTFE), a large amount of dust exists within the PTFE, affecting its concentration and consequently impacting subsequent product manufacturing operations. Therefore, dust removal is necessary after the finished PTFE product is manufactured. Existing technologies typically involve passing PTFE gas through a filter canister equipped with a filter element to remove dust. However, the filtered dust contains trace amounts of PTFE, making it toxic. Furthermore, since the filter element requires frequent replacement and cleaning, workers are susceptible to exposure to this toxic dust, potentially affecting their health. Therefore, we propose a dust removal device and method for finished PTFE products. Summary of the Invention

[0004] The purpose of this invention is to provide a dust removal device and method for finished tetrafluoroethylene products, so as to solve the problems mentioned in the background art.

[0008] Preferably, the energizing component includes multiple sets of conductive rods, which are fixedly connected to multiple sets of iron rods respectively. The outer surface of each conductive rod is fitted with a conductive ring, and each set of conductive rings is connected with a wire. The top end of each wire is connected to a connector to facilitate control of the energization of the iron rods.

[0009] Preferably, the dust collection component includes multiple sets of dust collection pipes, which are respectively connected to multiple sets of scrapers and rotatably connected to the filter box. One end of each dust collection pipe is connected to a central pipe, and the top end of the central pipe is connected to a connecting pipe. One end of the connecting pipe is connected to a fan hood, and the other end of the fan hood is connected to a dust exhaust pipe, which is connected to a dust processor. The fan hood is rotatably connected to a fan wheel, and the fan wheel is connected to a rotation limiter connected to the drive component. The dust collection pipe is connected to a swinging component for driving the scrapers to swing, which facilitates automatic dust handling.

[0010] Preferably, the driving component includes a motor fixedly connected to the filter box, a coupling fixedly connected to the output end of the motor, a drive shaft fixedly connected to one end of the coupling, the drive shaft being movably connected to the impeller and rotatably connected to the fan cover, and a rotating rod fixedly connected to the top end of the drive shaft and slidably connected to the connecting shaft, which helps to improve the driving force.

[0011] Preferably, the rotation limiting component includes a rotating disk fixedly connected to the wind turbine, the rotating disk being movably connected to the drive shaft, and a ratchet gear fixedly connected to the drive shaft being rotatably connected to the rotating disk. A pawl meshes with the outer side of the ratchet gear, and a rotating column fixedly connected to the rotating disk is fixedly connected to the pawl. A connecting piece is fixedly connected to one end of the rotating column, and a first rotary spring fixedly connected to the rotating disk is fixedly connected to the connecting piece, facilitating control of the wind turbine's rotation.

[0012] Preferably, the oscillating component includes multiple sets of fixed rings, which are respectively fixedly connected to multiple sets of suction pipes. A second rotary spring fixedly connected to the filter box is fixedly connected to each fixed ring. A third bevel gear is fixedly connected to each suction pipe. A fourth bevel gear meshes with the outer side of the third bevel gear. A connecting post fixedly connected to the rotating rod is fixedly connected to one end of the fourth bevel gear. A second connecting frame rotatably connected to the suction pipe is rotatably connected to the outer surface of the connecting post.

[0014] A dust removal method for finished tetrafluoroethylene products includes the following steps:

[0015] S1: Installation: Connect the end of the pipe that generates tetrafluoroethylene gas to the inlet pipe, connect the exhaust pipe to the storage tank that stores tetrafluoroethylene gas, and connect the dust exhaust pipe to the dust processor.

[0016] S2: Dust removal: Gas is introduced, the power is turned on to make the iron rod have static electricity, and the motor is started to drive the rod to rotate. The rotating iron rod adsorbs dust.

[0017] S3: Dust handling: After adsorption is completed, the motor runs in reverse to drive the impeller to rotate. Together with the rotation of the iron rod and the action of the scraper, the dust is scraped off. At this time, the dust scraped off by the suction force generated by the impeller is sent to the dust processor for processing.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention incorporates an iron rod, an energized component, and a rotating component. The energized component causes the iron rod to become electrostatically charged, which, combined with the rotating component, drives the iron rod to rotate. This electrostatically charged iron rod then adsorbs dust from the tetrafluoroethylene (PTFE). During dust removal, a scraper removes the dust, and a suction device then discharges the scraped dust through a dust extraction pipe to a dust processor for disinfection. Therefore, the electrostatically charged iron rod and scraper enable automatic dust adsorption and processing, eliminating the need for manual handling and solving the problem in existing technologies where manual dust removal exposes operators to toxic dust, impacting their health.

Detailed Implementation

[0036] 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.

[0037] Example 1

[0038] Please see Figures 1-4 as well as Figure 9The diagram shows a dust removal device for finished tetrafluoroethylene products, including a filter box 1. An inlet pipe 2 and an outlet pipe 3 are connected to both ends of the filter box 1, respectively. A flow guide layer 4 is fixedly connected inside the filter box 1. A sliding frame 5, slidably connected to the filter box 1, is installed at one end of the flow guide layer 4. An elastic element 6 is connected to one end of the sliding frame 5. The device also includes multiple sets of iron rods 7, arranged vertically and equidistantly within the sliding frame 5. One end of each iron rod 7 is connected to a power supply element 8 for energizing the iron rod 7, and the other end is connected to a rotating element 9 for rotating the iron rod 7. The device also includes scrapers 10, the same number as the iron rods 7, arranged vertically and equidistantly on one side of each iron rod 7. The scrapers 10 are hollow and have several sets of through holes 11. A dust-collecting element 12 for absorbing scraped-off dust is also connected to the scrapers 10.

[0039] It should be noted that when removing dust from tetrafluoroethylene, one end of the inlet pipe 2 is connected to the gas generating end, and one end of the outlet pipe 3 is connected to the storage tank. At this time, the gas enters the filter box 1 through the inlet pipe 2 and comes into contact with the iron rod 7 through the flow guide layer 4. The iron rod 7 becomes statically charged due to the conductive component, and the dust is attracted by the static electricity. The rotating component 9 causes the iron rod 7 to rotate, so the outer surface of the iron rod 7 is evenly covered with dust, thus effectively removing dust from the tetrafluoroethylene.

[0040] It is worth noting that after the gas is introduced, the sliding frame 5 slides due to the action of the elastic element 6, thereby moving the iron rod 7 away from the scraper 10. At this time, the scraper 10 will not come into contact with the iron rod 7, thus avoiding the scraper 10 from scraping off the dust during the adsorption process and affecting the subsequent dust treatment.

[0041] It should also be noted that after the gas is introduced, the gas supply stops, and the elastic element 6 drives the sliding frame 5 to reset, which in turn drives the iron rod 7 to reset and contact the scraper 10. At this time, through the cooperation of the rotating element 9 and the dust suction element 12, the dust adsorbed on the outer surface of the iron rod 7 is scraped off and sucked away by the dust suction element 12 and discharged.

[0042] Please refer to Figures 3-5 The rotating component 9 in the figure includes multiple sets of rotating shafts 13, which are fixedly connected to multiple sets of iron rods 7 respectively. A first spur gear 14 is fixedly connected to the outer surface of the rotating shaft 13. The multiple sets of first spur gears 14 are meshed with each other. One end of one set of rotating shafts 13 extends to the outside of the filter box 1 and is slidably connected to the filter box 1. A first bevel gear is fixedly connected to one end of the rotating shaft 13. A second bevel gear 16 meshes with the outside of the first bevel gear 15. A connecting shaft 17 is fixedly connected to the axis of the second bevel gear 16. A first connecting frame 18 is rotatably connected to the connecting shaft 17 and is rotatably connected to the rotating shaft 13. A driving component 19 is connected to one end of the connecting shaft 17.

[0043] It should be noted that since the iron rod 7 is cylindrical and the gas enters from one end, the efficiency of dust adsorption by the wind on the iron rod 7 is low when the iron rod 7 is not rotating. Therefore, the driving component 19 drives the connecting shaft 17 to rotate, which in turn drives the second bevel gear 16 to rotate, which in turn drives the first bevel gear 15 to rotate, which in turn drives the rotating shaft 13 to rotate, which in turn drives the first spur gear 14 to rotate. Since multiple sets of first spur gears 14 are meshed with each other, when one set of first spur gears 14 rotates, all the other sets of first spur gears 14 rotate as well. Therefore, the rotating shaft 13 drives all the iron rods 7 to rotate simultaneously, thereby improving the dust adsorption efficiency of the iron rod 7.

[0044] It is worth noting that the first connecting bracket 18 is mounted on the rotating shaft 13 and the connecting shaft 17. Therefore, after the sliding bracket 5 is reset, the connecting bracket can keep the first bevel gear 15 and the second bevel gear 16 meshing.

[0045] Please refer to Figure 4 and Figure 7 The elastic element 6 shown in the figure includes a baffle 20 fixedly connected to the sliding frame 5. The baffle 20 has several sets of ventilation holes 21, and a spring 22 fixedly connected to the filter box 1 is fixedly connected to the corner of the baffle 20.

[0046] It should be noted that after the gas is introduced into the filter box 1, the gas can be normally delivered to the outlet pipe 3 due to the action of the baffle 20 and the air vent 21. However, due to the presence of the baffle 20, the gas will exert a pushing force on the baffle 20, causing the baffle 20 to move, which in turn drives the sliding frame 5 to move, which in turn drives the iron rod 7 to move, thus causing the iron rod 7 to move away from the scraper 10 during the air supply process.

[0047] It is worth noting that after the ventilation ends, the baffle 20 loses the squeezing effect of the gas, and the spring 22 will drive the baffle 20 to reset, which in turn drives the sliding frame 5 and the iron rod 7 to reset, thus making the iron rod 7 contact the scraper 10, which facilitates the subsequent treatment of dust.

[0048] Please refer to Figure 4 and Figure 7 as well as Figure 8 The energizing component 8 includes multiple sets of conductive rods 23, which are fixedly connected to multiple sets of iron rods 7 respectively. The outer surface of the conductive rods 23 is fitted with conductive rings 24, and each set of conductive rings 24 is connected with a wire 25. The top end of the wire 25 is connected to a connector 26.

[0049] It should be noted that: when connecting to external equipment through connector 26, static electricity is transferred to iron rod 7 through the action of wire 25, conductive ring 24 and conductive rod 23, and the dust in the tetrafluoroethylene is adsorbed by the static-charged iron rod 7.

[0050] Please refer to Figures 11-13 The dust collection component 12 shown in the figure includes multiple sets of dust collection pipes 27. The multiple sets of dust collection pipes 27 are respectively connected to multiple sets of scrapers 10 and rotatably connected to the filter box 1. One end of the dust collection pipe 27 is connected to a central pipe 28, and the top end of the central pipe 28 is connected to a connecting pipe 29. One end of the connecting pipe 29 is connected to a fan hood 30, and the other end of the fan hood 30 is connected to a dust exhaust pipe 31. The dust exhaust pipe 31 is connected to a dust processor. Inside the fan hood 30, a fan wheel 32 is rotatably connected. A rotation limiting member 33 connected to the drive component 19 is connected to the fan wheel 32. A swinging member 34 for driving the scraper 10 to swing is connected to the dust collection pipe 27.

[0051] It should be noted that when the dust is being treated, the sliding frame 5 moves the iron rod 7 to contact the scraper 10 after the ventilation ends. At this time, the drive component 19 reverses, thus causing the iron rod 7 to reverse as well. Since the iron rod 7 is in contact with the scraper 10, the dust adsorbed on the outer surface of the iron rod 7 will be scraped off. At the same time, the reverse action of the motor 35, combined with the action of the rotation limiter 33, drives the impeller 32 to rotate, thus creating a negative pressure inside the hood 30. The scraped dust is then absorbed into the hood 30 through the through hole 11, the suction pipe 27, and the collection pipe 28. The dust is then transported to the dust processor through the dust exhaust pipe 31 for disinfection, preventing the leakage of toxic dust.

[0052] It is worth noting that during the process of the iron rod 7 adsorbing dust, the drive component 19 rotates forward. Therefore, due to the presence of the rotation limiting component 33, the rotation of the drive component 19 will not drive the impeller 32 to rotate. When the dust is being treated, the drive component 19 rotates in reverse. Therefore, the rotation limiting component 33 runs and drives the impeller 32 to rotate, thereby generating negative pressure inside the fan cover 30.

[0053] It should also be noted that during the dust adsorption process of the iron rod 7, the scraper 10 does not contact the iron rod 7. At this time, the drive component 19 will drive the iron rod 7 to rotate. During the operation of the drive component 19, the swing component 34 will also operate. In turn, the action of the swing component 34 will drive the scraper 10 to swing up and down, thereby guiding the PTFE airflow. This ensures that all the iron rods 7 can effectively adsorb dust, improving the dust removal efficiency.

[0054] One method for dust removal from a finished tetrafluoroethylene product includes the following steps:

[0055] S1: Installation: Connect the end of the pipe that generates tetrafluoroethylene gas to the inlet pipe, connect the exhaust pipe to the storage tank that stores tetrafluoroethylene gas, and connect the dust exhaust pipe to the dust processor.

[0056] S2: Dust removal: Gas is introduced, the power is turned on to make the iron rod have static electricity, and the motor is started to drive the rod to rotate. The rotating iron rod adsorbs dust.

[0057] S3: Dust handling: After adsorption is completed, the motor runs in reverse to drive the impeller to rotate. Together with the rotation of the iron rod and the action of the scraper, the dust is scraped off. At this time, the dust scraped off by the suction force generated by the impeller is sent to the dust processor for processing.

[0058] Example 2

[0059] Please see Figure 9 and Figure 10 The swinging component 34 shown in the figure includes multiple sets of fixed rings 44, which are fixedly connected to multiple sets of suction pipes 27 respectively. A second rotary spring 45 fixedly connected to the filter box 1 is fixedly connected to the fixed ring 44. A third bevel gear 46 is fixedly connected to the suction pipe 27. A fourth bevel gear 47 meshes with the outer side of the third bevel gear 46. A connecting post 50 fixedly connected to the rotating rod 49 is fixedly connected to one end of the fourth bevel gear 47. A second connecting frame 51 rotatably connected to the suction pipe 27 is rotatably connected to the outer surface of the connecting post 50. A linkage component 48 for synchronously swinging multiple sets of suction pipes 27 is connected to the other end of the suction pipe 27.

[0060] It should be noted that when the drive component 19 is running, it will drive the connecting column 50 to rotate, which in turn drives the fourth bevel gear 47 to rotate, which in turn drives the third bevel gear 46 to rotate, thereby driving the suction pipe 27 to rotate. Since the fourth bevel gear 47 is in a missing tooth state, when the missing tooth position of the fourth bevel gear 47 corresponds to the third bevel gear 46, the third bevel gear 46 and the fourth bevel gear 47 disengage. Therefore, through the action of the second rotary spring 45, the third bevel gear 46 drives the suction pipe 27 to reset, thus causing the suction pipe 27 to swing up and down. While the suction pipe 27 is swinging, through the action of the linkage component 48, the other suction pipes 27 swing synchronously, thus driving all the scrapers 10 to swing up and down synchronously.

[0061] It is worth noting that during the dust adsorption process of the iron rod 7, the scraper 10 is not in contact with the iron rod 7. The up-and-down swing of the scraper 10 guides the PTFE airflow, improving the dust adsorption efficiency of the iron rod 7. When cleaning the outer surface of the iron rod 7, the scraper 10 still swings. There are two states between the scraper 10 and the iron rod 7: first, they are in contact, and second, they are moving away. When they are in contact, the dust on the outer surface of the iron rod 7 is scraped off and then sucked away by the suction component 12. When they are moving away from the iron rod 7, the dust cannot be scraped off, but the position of the through hole 11 changes, so the suspended dust after being scraped off can be absorbed, improving the processing efficiency.

[0062] Please refer to Figure 2 and Figure 11 The linkage 48 shown in the figure includes multiple sets of second flat gears 52, which are fixedly connected to multiple sets of suction pipes 27 respectively, and the outer side of the second flat gears 52 is connected to a gear belt 53.

[0063] It should be noted that when the vacuum cleaner tube 27 rotates, it will drive the second flat gear 52, which is fixedly connected to it, to rotate. This will drive the gear belt 53 to rotate. Through the transmission action of the gear belt 53, all the second flat gears 52 rotate synchronously, thus enabling the vacuum cleaner tube 27 to maintain synchronous rotation.

[0064] The rest of the structure is the same as in Example 1.

[0065] Example 3

[0066] Please see Figure 5 and Figure 12 as well as Figure 13 The driving component 19 shown in the figure includes a motor 35 fixedly connected to the filter box 1. A coupling 36 is fixedly connected to the output end of the motor 35. A drive shaft 37 is fixedly connected to one end of the coupling 36. The drive shaft 37 is movably connected to the impeller 32 and rotatably connected to the fan cover 30. A rotating rod 49 that is slidably connected to the connecting shaft 17 is fixedly connected to the top end of the drive shaft 37.

[0067] It should be noted that: by starting the motor 35, the motor 35 will drive the coupling 36 to rotate, which in turn drives the drive shaft 37 to rotate, which in turn drives the rotating rod 49 to rotate, which in turn drives the connecting shaft 17 that is slidably connected to it to rotate, and also drives the connecting column 50 that is fixedly connected to it to rotate.

[0068] It is worth noting that during the sliding process of the sliding frame 5, the rotating shaft 13 will also slide. At this time, the first connecting frame 18 causes the first bevel gear 15, the second bevel gear 16, and the connecting shaft 17 to slide accordingly. Since the connecting shaft 17 and the rotating rod 49 are slidably connected, after the connecting shaft 17 slides a certain distance, when the motor 35 drives the rotating rod 49 to rotate, the rotating rod 49 will still drive the connecting shaft 17 to rotate. Therefore, when the sliding frame 5 is at the end or the beginning position, the rotation of the motor 35 can drive the connecting shaft 17 to rotate, and then drive the rotating shaft 13 and the iron rod 7 to rotate through the action of the first bevel gear 15 and the second bevel gear 16.

[0069] Please refer to Figure 14 and Figure 15 The limiting component 33 shown in the figure includes a rotating disk 38 fixedly connected to the wind turbine 32. The rotating disk 38 is movably connected to the drive shaft 37, and a ratchet 39 fixedly connected to the drive shaft 37 is rotatably connected to the rotating disk 38. A pawl 40 is engaged on the outer side of the ratchet 39. A rotating column 41 rotatably connected to the rotating disk 38 is fixedly connected to the pawl 40. A connecting piece 42 is fixedly connected to one end of the rotating column 41. A first rotary spring 43 fixedly connected to the rotating disk 38 is fixedly connected to the connecting piece 42.

[0070] It should be noted that when adsorbing dust, the motor 35 drives the drive shaft 37 to rotate forward, which in turn drives the ratchet 39 to rotate forward. At this time, the ratchet 39 will push the pawl 40 to rotate, so that the ratchet 39 and the pawl 40 cannot mesh, and therefore the pawl 40 will not rotate, and thus the rotating disk 38 cannot rotate. When cleaning dust, the motor 35 reverses, which drives the drive shaft 37 to reverse, which in turn drives the ratchet 39 to reverse. At this time, the ratchet 39 rotates towards the tip of the pawl 40 and cannot disengage from the pawl 40, so the pawl 40 and the rotating disk 38 will rotate, thus driving the impeller 32 to rotate.

[0071] It is worth noting that: due to the action of the first rotary spring 43, when the ratchet 39 pushes the pawl 40 to rotate, the first rotary spring 43 contracts. After the ratchet 39 stops rotating, the first rotary spring 43 resets and drives the pawl 40 to mesh with the ratchet 39 again. The rest of the structure is the same as other embodiments.

[0072] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
