Description

Technical Field

[0001] The utility model relates to the field of carbon nanotube film production, in particular to a gas-solid separation device used for carbon nanotube film production. Background Art

[0002] Carbon nanotube film is a film structure composed of carbon nanotubes. Before producing carbon nanotube film, a gas-solid separation device is used to process the carbon nanotube powder to obtain pure carbon nanotubes suitable for growing film. Some businesses use cyclone separators to perform gas-solid separation. The cyclone separators rely on the rotational motion caused by the tangential introduction of airflow to throw solid particles with large inertial centrifugal force to the outer wall to separate. In the separation process, since the carbon nanotube powder is too fine, it is inevitable that the exhaust gas contains trace amounts of powder, which not only wastes raw materials, but also discharges the powder into the external environment, causing pollution. Some filters are installed, but the removal is too troublesome, reducing work efficiency.

[0003] After searching, Chinese patent announcement number: CN220346184U discloses a carbon nanotube powder gas-solid separation device, including a cyclone separator and a filter assembly, a dust-containing gas inlet pipe is arranged on the left side of the upper end of the cyclone separator, a gas outlet pipe is arranged in the middle of the top of the cyclone separator, the lower end of the cyclone separator is conical, a discharge assembly is arranged at the bottom of the cyclone separator, and a filter assembly is arranged at the end of the gas outlet pipe. The filter assembly includes a shell fixedly arranged at the end of the gas outlet pipe, an air outlet is arranged on the upper right side of the shell, a discharge port is arranged at the bottom of the shell, a ventilation plate is arranged inside the shell, a plurality of sleeves are arranged through the ventilation plate, a filter cartridge is arranged on the outer wall of the bottom of the sleeve, a filter bag is arranged on the outer wall of the filter cartridge, and a rubber ring is arranged on the upper end of the outer wall of the filter bag. In the utility model, the filter assembly can prevent the cyclone separator from causing trace powder contained in the gas to be discharged due to the powder being too fine, and the filter assembly can intercept the trace powder.

[0004] In the above technology, although the risk of carbon nanotubes being discharged from the exhaust pipe can be avoided through the designed filter assembly, the filter assembly is arranged on the inner wall of the exhaust pipe and is fixed therein by bolts. It is too troublesome to disassemble and assemble, which brings inconvenience to later maintenance. The top cover of some cyclone separators is fixed by multiple sets of bolts. When cleaning, the bolts need to be disassembled and assembled repeatedly, which is too troublesome and reduces work efficiency. Therefore, a gas-solid separation device for carbon nanotube film production is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 4 The utility model provides an embodiment: a gas-solid separation device for the production of carbon nanotube films, including a cyclone separator 1. The cyclone separator 1 is a prior art and is a commonly used gas-solid separation device, mainly used to separate a mixture of solid particles and gas. It uses airflow to form a rotating flow in a cylindrical or conical container to generate centrifugal force to cause particles to settle or be thrown out of the airflow, thereby achieving separation. The upper surface of the cyclone separator 1 is in contact with a cover plate 3, which can be removed, mainly to provide convenience for subsequent cleaning and maintenance. The upper surface of the cover plate 3 is fixedly connected with an air outlet pipe 2, and the upper surface of the air outlet pipe 2 is opened. A through groove 8 is provided, a filter assembly 5 is provided on the inner wall of the air outlet pipe 2, a rectangular groove 2 6 is provided on the upper surface of the cover plate 3, a disassembly assembly 4 is provided on the upper surface of the cover plate 3, the filter assembly 5 includes a fixing block 51, the fixing block 51 slides on the inner wall of the through groove 8, the through groove 8 is adapted to the fixing block 51 to ensure the stability of the connection, a rectangular groove 59 is provided on the left surface of the fixing block 51, the upper surface of the air outlet pipe 2 is fixedly connected with a fixing plate 510 by bolts, the fixing plate 510 is fixed to the upper surface of the air outlet pipe 2 by bolts, which can ensure the stability of the connection of the filter assembly 5, and the lower surface of the fixing plate 510 contacts the upper surface of the fixing block 51.

[0032] Reference Figure 1 - Figure 2 The disassembly and assembly component 4 includes a connecting block 42, the lower surface of the front end of the connecting block 42 is slidably connected to the inner wall of the rectangular groove 6, and the left surface of the rear end of the connecting block 42 is threadedly connected with a bidirectional threaded rod 41. The bidirectional threaded rod 41 is a prior art, and two sets of threads with different rotation directions are arranged on the outer walls at both ends. When the bidirectional threaded rod 41 is rotated, the connecting blocks 42 connected to its two ends move in relative or opposite directions to ensure the synchronization of the structural movement. The front end of the right surface of the connecting block 42 is fixedly connected with a connecting rod 43, and the left surface of the bottom end of the connecting rod 43 is fixedly connected with an arc block 44. The curvature of the left surface of the arc block 44 is similar to the curvature of the outer wall at the top of the cyclone separator 1 to ensure the stability of the fixation. The bottom end of the left surface of the arc block 44 contacts the top of the right surface of the cyclone separator 1, and the bottom end of the left surface of the arc block 44 is fixedly connected with a plug-in rod 45.

[0033] Reference Figure 3The inner wall of the rectangular groove 59 is elastically connected with a slider 57 through a spring 58. The spring 58 always pushes the slider 57 downward by its own elasticity to ensure that it can quickly reset after being squeezed. The slider 57 is slidably connected to the inner wall of the rectangular groove 59. When the filter assembly 5 is installed on the inner wall of the air outlet duct 2, the slider 57 is no longer squeezed by the squeezing plate 56, and its top will be on the inner wall of the rectangular groove 59, and the bottom will be on the inner wall of the annular groove 7, ensuring that the slider 57 can only move up and down. One end of the spring 58 is fixedly connected to the upper surface of the slider 57, and the other end of the spring 58 is fixedly connected to the inner wall of the rectangular groove 59.

[0034] Reference Figure 3 A filter plate 55 is fixedly connected to the left surface of the slider 57, a ring 54 is rotatably connected to the upper surface of the filter plate 55, a round rod 53 is slidably connected to the upper surface of the ring 54, a fan 52 is fixedly connected to the upper surface of the round rod 53, and the fan 52 is driven by the component force inside the air outlet duct 2, and there is no need to install other electronic equipment, thereby reducing costs.

[0035] Reference Figure 2 - Figure 3 A squeezing plate 56 is fixedly connected to the lower surface of the round rod 53, and an arc-shaped surface is provided on the upper surface of the front end of the squeezing plate 56. The arc-shaped surface ensures that the squeezing plate 56 can smoothly push the slider 57 to move. An annular groove 7 is provided on the lower side of the inner wall of the air outlet pipe 2 near the through groove 8. The front end of the squeezing plate 56 slides on the inner wall of the annular groove 7. The through groove 8 is connected to the annular groove 7, which can ensure that the filter assembly 5 is smoothly installed on the inner wall of the air outlet pipe 2.

[0036] Reference Figure 1 - Figure 2 A groove is provided at the top of the right surface of the cyclone separator 1, and the left surface of the plug-in rod 45 contacts the inner wall of the groove. Multiple groups of connecting blocks 42, connecting rods 43, and arc blocks 44 are provided, and the multiple groups of connecting blocks 42, connecting rods 43, and arc blocks 44 are symmetrically arranged with the center line of the bidirectional threaded rod 41 as the symmetry axis. Multiple groups of connecting blocks 42, connecting rods 43, and arc blocks 44 are provided to ensure the stability of the connection between the cover plate 3 and the cyclone separator 1.

[0037] Working principle: When in use, the product is discharged into the cyclone separator 1 through the feed pipe on the side thereof, and the cyclone separator 1 is started at the same time. Under the action of the device, the product will be thrown onto the inner wall of the cyclone separator 1 by centrifugal force and discharged downward, while the gas inside the product will flow upward through the air outlet pipe 2. The gas flowing upward will drive the fan 52 to rotate, and the fan 52 will simultaneously drive the round rod 53 and the extrusion plate 56 to rotate. When the extrusion plate 56 contacts the slider 57, it will push the slider 57 to move upward and squeeze the spring 58. When the extrusion plate 56 does not contact the slider 57, the spring 58 will push the slider 57 to move in the opposite direction for reset through its own elasticity. In this process, the filter plate 55 will follow the slider 57 through the ring 54 and vibrate up and down repeatedly, so as to prevent the product from sticking to the lower surface of the filter plate 55.

[0038] When the filter assembly 5 needs to be disassembled for replacement or cleaning, it is only necessary to turn down the bolts of the fixing plate 510 and remove the fixing plate 510. At this time, the fixing block 51 can be pulled out from the inner wall of the through groove 8. Before pulling, ensure that the front end of the extrusion plate 56 overlaps with the through groove 8, so that the filter assembly 5 can be smoothly disassembled. When installing, first ensure that the extrusion plate 56 overlaps with the through groove 8, and then insert the fixing block 51 into the inner wall of the through groove 8 until the extrusion plate 56 enters the inner wall of the annular groove 7. In this way, the fixing plate 510 can be fixed to the upper surface of the air outlet duct 2 by bolts, and the lower surface of the fixing plate 510 is in contact with the upper surface of the fixing block 51.

[0039] When it is necessary to open the cover 3 and clean its inner wall, rotate the two-way threaded rod 41. At this time, the connecting blocks 42 threadedly connected to the outer walls at both ends of the two-way threaded rod 41 will move in the opposite direction. The connecting blocks 42 will drive the arc blocks 44 to move through the connecting rods 43, and the arc blocks 44 will drive the plug-in rods 45 to move until the plug-in rods 45 are completely separated from the inner wall of the groove. In this way, the cover 3 can be removed. When installing, cover the cover 3 on the upper surface of the cyclone separator 1, and then reverse the two-way threaded rod 41. At the same time, the subsequent structural coordination method is used until the plug-in rods 45 are fully inserted into the inner wall of the groove, so that the cyclone separator 1 and the cover 3 can be fixed together.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
