[0002] Carbon nanotubes, also known as buckytubes, are one-dimensional quantum materials with a special structure. Their radial dimensions are in the nanometer range, their axial dimensions are in the micrometer range, and both ends of the tubes are basically sealed. Carbon nanotubes are mainly composed of several to dozens of layers of coaxial circular tubes composed of carbon atoms arranged in a hexagonal pattern. Macroscopically, they are a powdery solid material. During their production process, the wet carbon nanotubes need to be dried.
[0003] The traditional carbon nanotube drying process generally involves placing the wet carbon nanotube material into a drying oven for hot air drying. However, in practice, we have found that simply using hot air drying not only easily brings some powdered carbon nanotube material out of the outside, but also easily discharges high-temperature gas directly to the outside, causing unnecessary high-temperature waste. Therefore, how to solve this problem is what we need to consider. Utility Model Content

DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-Figure 3 A carbon nanotube drying device comprises a bottom plate 1, two vertical plates 2 are symmetrically fixedly connected to the upper end of the bottom plate 1, a rotating cylinder 3 is arranged between the two vertical plates 2, an arc-shaped sealing door 4 is installed on the rotating cylinder 3, and rotating tubes 8 are fixedly connected to the left and right sides of the rotating cylinder 3, and the other ends of the two rotating tubes 8 penetrate the corresponding vertical plates 2 and are rotatably connected to the corresponding vertical plates 2;
[0020] Wherein, it also includes a gas circulation mechanism, which includes a reversible fan 7 installed on the left side of the left vertical plate 2. The reversible fan 7 is a fan that can change the wind direction. It is a prior art. A first rectangular box 5 and a second rectangular box 6 are installed on the left side of the vertical plate 2 on the left. A heating wire 14 is installed in the first rectangular box 5. A placement net 12 is installed inside the second rectangular box 6. Calcium carbonate particles are placed on the placement net 12. A sealing door body not shown in the figure is also installed on the rear side of the second rectangular box 6 for subsequent replacement of calcium carbonate particles. A rotating joint 9 is installed at the other end of each of the two rotating tubes 8. The bottom space of the first rectangular box 5 is connected to the top space of the second rectangular box 6 through a second connecting pipe 13. The top space of the first rectangular box 5 is connected to the other end of the rotating joint 9 on the left. One end of the reversible fan 7 is connected to the bottom space of the second rectangular box 6. The other end of the reversible fan 7 is connected to the other end of the rotating joint 9 on the right. The opposite ends of the two rotating tubes 8 extend into the rotating cylinder 3. Filters 11 are installed at the opposite ends of the two rotating tubes 8.
[0021] It also includes a rotating mechanism, which is used to drive the rotating drum 3 to rotate. The rotating mechanism includes a motor 15 installed on the right side of the right vertical plate 2. The output shaft of the motor 15 passes through the right vertical plate 2 and is connected to the right rotating tube 8 through a transmission member 16. The transmission member 16 includes two pulleys, which are respectively installed on the right rotating tube 8 and the output shaft of the motor 15. The two pulleys are connected through a transmission belt.
[0022] In the utility model, after use, the carbon nanotubes to be dried are first put into the rotating cylinder 3, and the height of the carbon nanotube powder after being put is lower than the height of the rotating tube 8. Then the arc sealing door 4 is closed, and the electric heating wire 14, the reversible fan 7 and the motor 15 are started at the same time. The reversible fan 7 and the electric heating wire 14 are started, and a circulating gas flow is generated inside the rotating cylinder 3, the first rectangular box 5, the second rectangular box 6, the reversible fan 7 and the rotating cylinder 3. The circulating gas flow utilizes the heating of the electric heating wire 14 to heat the material, and the heated air passes through the calcium carbonate particles and enters the rotating cylinder 3 again after being dried, so as to avoid the waste caused by the discharge of hot air to the outside. The start of the motor 15 will make the rotating cylinder 3 rotate. The rotation of the rotating cylinder 3 can make the material automatically flip, and the contact with the hot air is more uniform, and the drying effect is better.
[0023] In addition, some of the raised material powder will adhere to the filter screen 11 on the left side with the flow of air. When too much adhesion occurs, the reversing function of the reversible fan 7 can be started to change the direction of the circulating air flow, so that the left filter screen 11 can be blown and the right filter screen 11 can be sucked, so as to achieve automatic clearing. When the right filter screen 11 is blocked, the reversible fan 7 can be started again to reverse the direction, so as to ensure the continuity of drying.
[0024] After the drying is completed, the material receiving box is placed on the bottom plate 1, and then rotated to the point where the arc-shaped sealing door 4 faces downward, and the arc-shaped sealing door 4 is opened, and the material falls into the material receiving box under the action of gravity.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
