Description

Technical Field

[0001] The invention relates to the technical field of carbon nanotube purification, and in particular to a cooling device for a carbon nanotube purification device. Background Art

[0002] Carbon nanotubes are a type of tubular nanoscale graphite crystals. They are seamless nanoscale tubes formed by curling single or multiple layers of graphite sheets around a central axis at a certain spiral angle. The C in each layer is SP2 hybridized to form a cylindrical surface with a hexagonal plane. Carbon nanotubes have an extremely large specific surface area, light weight but superb mechanical strength, excellent conductivity, and good physical and chemical stability. During the preparation process of carbon nanotubes, some associated impurities will be produced, which will limit the application of carbon nanotubes in functional devices. Therefore, a carbon nanotube purification device is required to purify the carbon nanotubes.

[0003] When a cooling device is used to cool the purified carbon nanotubes, the carbon nanotubes are usually directly placed in a barrel or a tank, and the carbon nanotube material inside is stirred by a stirring device inside the barrel or the tank, so that the material is in full contact with the inner wall of the barrel or the tank, and the coolant outside the tank cools the carbon nanotubes. However, simply stirring the carbon nanotubes by a stirring device inside the tank cannot fully replace the positions of the carbon nanotubes located at the bottom of the tank with those located at the top of the tank, and the discharge port of the tank is usually set at the bottom. After the carbon nanotube material enters the tank, part of it will directly enter the pipe of the discharge port and will not participate in cooling during the entire cooling process, resulting in poor cooling effect and low efficiency of the cooling device on the carbon nanotubes.

When cooling the purified carbon nanotubes, the carbon nanotubes are sent into the interior of the inner barrel 9 through the material tube 6, and the interior of the material tube 6 is closed by the valve device 3. The shaking device 2 is operated to shake the tank body 5 and the inner barrel 9, and the refrigerator 7 is started to make the cold air flow inside the cooling tube 8 to cool the liquid between the tank body 5 and the inner barrel 9. After the temperature of the liquid is reduced, it is transmitted to the interior of the inner barrel 9 so that the carbon nanotubes inside the inner barrel 9 are evenly cooled.

[0023] like Figure 2-6As shown, the shaking device 2 in this embodiment includes a first motor 21 arranged on one side of the frame 1, the output end of the first motor 21 is fixedly connected to one end of the first shaft rod 22, the other end of the first shaft rod 22 is rotatably arranged inside the frame 1 and fixedly connected to the frame rod 4, the inside of the frame rod 4 is rotatably connected with a second shaft rod 24, the second shaft rod 24 is axially perpendicular to the first shaft rod 22, a second bevel gear 25 is fixed on the top of the second shaft rod 24, and a first pulley 26 is fixed on the bottom of the second shaft rod 24, one side of the frame 1 is fixedly connected to a first bevel gear 23, the first bevel gear 23 is axially perpendicular to the second bevel gear 25 and meshes with the second bevel gear 25, the axial ends of the tank body 5 are respectively fixedly provided with third shaft rods 29, and the third shaft rods 29 located at the two axial ends are fixedly provided with the third shaft rods 29. The three shafts 29 are rotatably connected to the upper and lower ends of the frame rod 4 respectively, the bottom end of the third shaft 29 located at the bottom of the tank body 5 is fixedly connected to the second pulley 28, the outer edges of the first pulley 26 and the second pulley 28 are wrapped with a belt 27, the top of the tank body 5 is provided with a second motor 210, the output end of the second motor 210 is fixedly connected to a stirring rod 211, the stirring rod 211 is rotatably arranged inside the inner barrel 9, by arranging a shaking device 2, when cooling the purified carbon nanotubes, the carbon nanotubes are added to the interior of the inner barrel 9 through the material pipe 6, the interior of the material pipe 6 is closed by the valve device 3, the refrigerator 7 is started to make the cold air flow inside the cooling pipe 8 to cool the liquid between the tank body 5 and the inner barrel 9, and the liquid temperature drops At the same time, the second motor 210 at the top of the tank body 5 is started to drive the stirring rod 211 to rotate, and the carbon nanotubes inside the inner barrel 9 are stirred by the stirring rod 211 so that the carbon nanotubes inside the inner barrel 9 can contact the inner wall of the inner barrel 9 as comprehensively as possible, and then the first motor 21 is started to drive the first shaft rod 22 and the frame rod 4 to rotate, so that the tank body 5 and the inner barrel 9 on the outer surface of the frame rod 4 rotate with the first shaft rod 22 as the center. When the frame rod 4 rotates, the second bevel gear 25 at the top of the second shaft rod 24 will mesh with the first bevel gear 23 on one side of the frame 1, so that the second bevel gear 25 rotates and drives the first pulley 26 to rotate through the second shaft rod 24, and the first pulley 26 and belt 27 drive the second pulley 28 to be driven, and the third shaft 29 and the tank body 5 are driven by the second pulley 28 to rotate with the third shaft 29 as the center. After cooling is completed, the end of the tank body 5 provided with the material pipe 6 is rotated to be located below for easy discharge. The carbon nanotubes inside the inner barrel 9 are stirred by the stirring rod 211, and at the same time, the tank body 5 and the inner barrel 9 are rotated with the first shaft 22 as the center and the third shaft 29 as the center, so that the carbon nanotubes inside the inner barrel 9 can be in full contact with the inner wall of the inner barrel 9 as much as possible, and the feeding and discharging are operated from the material pipe 6, so as to avoid the carbon nanotubes inside the inner barrel 9 from accumulating at the bottom of the inner barrel 9 to affect the heat conduction effect, thereby improving the cooling efficiency of the cooling device.

[0024] Preferably, the stirring rod 211 in this embodiment is made of graphene material. Due to the stable chemical properties and good thermal conductivity of the graphene material, the stirring rod 211 is not easy to react with the carbon nanotubes when stirring the high-temperature carbon nanotubes and the heat conduction on the surface of the carbon nanotubes is faster.

[0025] Furthermore, if Figure 4-5 As shown, an annular groove 212 is provided on one side of the frame 1, and a positioning ring 213 is fixedly connected to one side of the frame rod 4. The positioning ring 213 is located inside the annular groove 212 and can rotate relative to it. When the first motor 21 is started to drive the first shaft rod 22 and the frame rod 4 to rotate, the positioning ring 213 on one side of the frame rod 4 will rotate in the positioning groove of the frame 1, thereby further limiting the angle between the frame rod 4 and the frame 1, and improving the stability of the frame rod 4 and the tank body 5 when the first shaft rod 22 drives them to rotate.

[0026] Similarly, if Figure 5-6 As shown, the bottom end of the frame rod 4 is fixedly connected with a plurality of groups of positioning plates 214, and each group of two positioning plates 214 is respectively located on both sides of the belt 27. By setting the positioning plates 214, the position of the belt 27 when it moves can be limited, and the belt 27 can be prevented from being separated from the outer edges of the first pulley 26 and the second pulley 28 as much as possible, thereby improving the stability of the shaking device 2 when in use. The top end of the third shaft rod 29 is fixedly connected with a disk 215, and the bottom end of the disk 215 is rotatably connected with a plurality of rotating wheels 216, which are rotatably arranged at the top end of the frame rod 4. When the third shaft rod 29 is driven to rotate by the second pulley 28, the rotating wheels 216 on the outer surface of the disk 215 at the top end of the third shaft rod 29 will move at the top end of the frame rod 4, thereby further limiting the angle between the third rotating shaft and the frame rod 4, thereby improving the stability of the third shaft rod 29 and the tank body 5 when they rotate with the third shaft rod 29 as the center of the circle.

[0027] like Figure 7-9As shown, the valve device 3 in this embodiment includes a control rod 31, which is rotatably extended into the interior of the material pipe 6. The outer edge of the bottom of the control rod 31 is fixedly connected to a sealing plate 32, and the outer edge of the sealing plate 32 matches the inner wall of the material pipe 6 (it is preferably set that the outer edge of the sealing plate 32 is slightly smaller than the inner wall of the material pipe 6 to facilitate the rotation process of the sealing plate). Grooves 33 are fixedly provided on both sides of the outer surface of the material pipe 6, and through holes 34 are opened in the groove blocks 33. The outer edge of the control rod 31 is slidably connected to a rectangular block 35. The bottom end of the rectangular block 35 is fixedly connected to two round rods 36, and the outer surfaces of the two round rods 36 are slidably connected to a cylinder 37. A spring 38 is provided at the top of the cylinder 37. The upper and lower ends of the spring 38 are respectively fixedly connected to the bottom end of the rectangular block 35 and the top end of the cylinder 37. The outer edge of the control rod 31 is threadedly connected to a threaded ring 39. Arc grooves 310 are provided on both sides of the inner wall of the material tube 6. An air passage 311 is provided inside the sealing plate 32. The inner wall of the control rod 31 is slidably connected to a piston block 312. The outer edge of the threaded ring 39 is threadedly connected to the piston block 312. The edge is connected with a collar 314, the top of the collar 314 is fixedly connected with a connecting rod 313, the end of the connecting rod 313 away from the collar 314 is fixedly connected to the top of the piston block 312, and rubber strips 315 are fixedly connected to both sides of the sealing plate 32. One end of the airway 311 is connected to one side of the inner wall of the two rubber strips 315. When the control rod 31 is rotated to make the sealing plate 32 seal the inside of the material pipe 6, the threaded ring 39 is rotated to make the threaded ring 39 move downward on the outer surface of the control rod 31 to further fix the position of the sealing plate 32. When the ring 39 rotates, the sleeve ring 314 will rotate synchronously with the threaded ring 39. At the same time, the threaded ring 39 moves downward and drives the piston block 312 to slide downward on the inner wall of the control rod 31 through the connecting rod 313, pressing the air inside the control rod 31 into the rubber strips 315 on both sides of the sealing plate 32 through the air channel 311, so that the rubber strips 315 expand and get stuck into the arc grooves 310 on both sides of the inner wall of the material pipe 6, thereby further sealing the contact between the sealing plate 32 and the material pipe 6 and improving the sealing effect of the sealing plate 32 on the inside of the material pipe 6.

[0028] As a further preference, convex strips 317 are provided at the edges of both sides of the inner wall of the arc groove 310, and the convex strips 317 are made of rubber. By providing the convex strips 317, the contact between the rubber strip 315 and the inner wall of the arc groove 310 can be further sealed, and the sealing effect of the rubber strip 315 being stuck in the arc groove 310 on the contact between the sealing plate 32 and the inner wall of the material pipe 6 is further improved. The outer surface of the threaded ring 39 is fixedly connected with a plurality of protrusions 316, which are distributed in a circle on the outer surface of the threaded ring 39. By pressing the protrusions 316 on the outer surface of the threaded ring 39 with your hand to push the threaded ring 39, the rotation of the threaded ring 39 can be controlled more conveniently without slipping of the hand.

[0029] The specific working process of this embodiment is as follows: When the purified carbon nanotubes are cooled, the control rod 31 is pushed to rotate so that the sealing plate 32 and the inside of the material tube 6 are perpendicular to each other and the inside of the material tube 6 is opened (such as Figure 8 As shown), at this time, the bottom ends of the two cylinders 37 will abut against the outer surface of the material tube 6 and compress the spring 38 on the outer surface of the round rod 36, so that the carbon nanotubes are added to the interior of the inner barrel 9 through the material tube 6, and then the control rod 31 is pushed to rotate and adjust the angle of the sealing plate 32 inside the material tube 6 to be parallel to the material tube 6 to close the inside of the material tube 6. At the same time, the rectangular block 35 will be above the groove block 33, and the spring 38 on the outer surface of the round rod 36 will return to its original shape and push the cylinder 37 to slide downward on the outer surface of the round rod 36 to insert the cylinder 37 into the outer surface of the groove block 33. The threaded ring 39 on the outer surface of the control rod 31 is then rotated to make the threaded ring 39 move downward on the outer surface of the control rod 31 to push the rectangular block 35 and the cylinder 37 downward, and the position of the cylinder 37 inside the through hole 34 is further fixed. The angle between the control rod 31 and the sealing plate 32 and the material pipe 6 is fixed to seal the inside of the material pipe 6. Then, the refrigerator 7 is started to make the cold air flow inside the cooling pipe 8 to cool the liquid between the tank body 5 and the inner barrel 9. After the liquid temperature is reduced, it is transmitted to the inner barrel 9 so that The carbon nanotubes in the inner barrel 9 are cooled down, and the second motor 210 at the top of the tank body 5 is started to drive the stirring rod 211 to rotate, and the carbon nanotubes in the inner barrel 9 are stirred by the stirring rod 211 so that the carbon nanotubes in the inner barrel 9 can contact the inner wall of the inner barrel 9 as much as possible, and the first motor 21 is started to drive the first shaft rod 22 and the frame rod 4 to rotate, so that the frame rod 4 and the outer surface of the tank body 5 and the inner barrel 9 rotate with the first shaft rod 22 as the center of the circle. When the frame rod 4 rotates, the second bevel gear 25 at the top of the second shaft rod 24 It will mesh with the first bevel gear 23 on one side of the frame 1, causing the second bevel gear 25 to rotate and drive the first pulley 26 to rotate through the second shaft 24, drive the second pulley 28 to rotate through the first pulley 26 and the belt 27, and drive the third shaft 29 and the tank body 5 to rotate with the third shaft 29 as the center through the second pulley 28. After cooling is completed, the end of the tank body 5 provided with the material pipe 6 is rotated to the bottom, and then the control rod 31 is pushed to rotate to open the material pipe 6, so that the carbon nanotubes inside the inner barrel 9 are output through the material pipe 6.

[0030] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
