[0002] After the existing storage device for carbon nanotubes stores the carbon nanotubes, it is necessary to inject an inert gas into the storage device to discharge the air in the storage device. However, the current air discharge method can only discharge the air between the tops of the storage devices, and the air between the carbon nanotubes cannot be discharged. This makes the air in the storage device unable to be fully discharged, resulting in a poor air discharge effect and affecting the storage effect of the carbon nanotubes.

[0003] Therefore, a storage device for preparing carbon nanotubes is needed to solve the problem that the air between the carbon nanotubes in the prior art cannot be discharged, resulting in a poor air discharge effect and affecting the storage effect of the carbon nanotubes.

[0029] Please refer to Figures 1-4 , the present utility model provides a storage device for preparing carbon nanotubes, including a storage tank 100 made of a material with good sealing performance, such as stainless steel or polymer plastic. A rotating pipe 102 is rotatably connected to the center of the bottom surface of the inner side wall of the storage tank 100. The bottom of the rotating pipe 102 passes through the bottom surface of the storage tank 100 movably. A plurality of arc-shaped blades 103 distributed in a circumferential manner are fixed on the outer side wall of the rotating pipe 102. Three exhaust pipes 200 distributed in a circumferential manner are connected to the bottom of the outer side wall of the rotating pipe 102 in a through manner. A plurality of uniformly distributed exhaust table holes 201 are connected to the bottom surface of the exhaust pipe 200 in a through manner. The exhaust pipe 200 is located below the arc-shaped blade 103 at the bottom. A plurality of desiccant boxes 500 distributed in a circumferential manner are fixed at a position close to the top of the inner side wall of the storage tank 100. An insulation layer 101 is fixed on the outer side wall of the storage tank 100. An air vent assembly is arranged on one side of the top surface of the storage tank 100.

[0030] Further, as Figure 3 shown, a sampling port 400 is opened on the top of the outer side wall of the storage tank 100. The sampling port 400 passes through the insulation layer 101. A sampling cover plate 401 is detachably connected in the sampling port 400.

[0031] By providing the sampling port 400, it is possible to take out a part of the carbon nanotubes for inspection or application when needed. By providing the sampling cover plate 401, when sampling is not carried out, the sampling port 400 can be sealed to prevent air and moisture from entering the storage tank 100.

[0032] Further, as Figure 3As shown, the ventilation component includes a fixing rod 107, which is fixed to one side of the top surface of the storage tank 100. The fixing rod 107 passes through the top surface of the heat preservation layer 101. One end of the fixing rod 107 is fixed with an air pump 106. The output end of the air pump 106 is connected to a connecting pipe 105. The input end of the air pump 106 is connected to an inert gas storage device. The connecting pipe 105 passes through the heat preservation layer 101 and one side of the top surface of the storage tank 100. A connecting pipe 104 is rotatably connected between the bottom of the outer side wall of the connecting pipe 105 and the top of the outer side wall of the rotating pipe 102.

[0033] By setting the air pump 106, inert gases such as nitrogen or xenon can be filled into the storage tank 100 to expel the air in the storage tank 100, further preventing the carbon nanotubes from being oxidized or contaminated. By setting the connecting pipe 104, when the rotating pipe 102 rotates, the connecting pipe 105 can be kept sealed with the rotating pipe 102.

[0034] The working process of this solution is as follows: When exhausting the air in the storage tank 100, first remove the sampling cover plate 401, and then start the motor 301. The rotation of the motor 301 drives the rotation of the rotating pipe 102, and the rotation of the rotating pipe 102 drives the rotation of the arc-shaped blade 103. The arc-shaped blade 103 stirs the carbon nanotubes in the storage tank 100, so that the gap between the carbon nanotubes can be increased. Then start the air pump 106. The air pump 106 injects inert gas into the rotating pipe 102, and then enters the exhaust pipe 200, and finally discharges from the exhaust table hole 201. After the inert gas discharges from the exhaust table hole 201, it moves upward, pushing the air between the carbon nanotubes upward, so that the air between the carbon nanotubes and the air at the top of the storage tank 100 are pushed out from the sampling port 400. After a period of time, turn off the air pump 106 and the motor 301 and cover the sampling cover plate 401 in the sampling port 400. The heat preservation layer 101 keeps the internal temperature of the storage tank 100 stable, preventing the performance of the carbon nanotubes from changing due to temperature changes. The desiccant box 500 can absorb the moisture in the storage tank 100 to keep the inside of the storage tank 100 dry. The sealing cover 600 can seal the storage tank 100 to prevent external air, moisture and impurities from entering the storage tank 100. The sampling port 400 enables part of the carbon nanotubes to be taken out for inspection or application when needed. The sampling cover plate 401 can seal the sampling port 400 when sampling is not carried out, avoiding the entry of air and moisture into the storage tank 100.

[0035] According to the above working process, it can be known that: through the provided air pump 106, inert gas can be injected into the storage tank 100. Through the provided arc-shaped blade 103, the carbon nanotubes can be stirred and driven by the arc-shaped blade 103, so that the gap between the carbon nanotubes can be increased. Through the provided rotating pipe 102, exhaust pipe 200 and exhaust table hole 201, the inert gas can be discharged from the exhaust table hole 201, and then the air between the carbon nanotubes and the air at the top inside the storage tank 100 can be discharged from the sampling port 400, so that the air between the carbon nanotubes and the air at the top inside the storage tank 100 can be fully discharged, improving the air discharge effect and avoiding affecting the storage effect of the carbon nanotubes when the air is not completely discharged.

[0036] Through the provided heat insulation layer 101, the temperature inside the storage tank 100 is kept stable, preventing the performance of the carbon nanotubes from changing due to temperature changes.

[0037] Through the provided desiccant box 500, the moisture inside the storage tank 100 can be absorbed, thus keeping the inside of the storage tank 100 dry.

[0038] Through the provided sealing cover 600, the opening of the storage tank 100 can be sealed, thus preventing external air, moisture and impurities from entering the storage tank 100.

[0039] Through the provided sampling port 400, part of the carbon nanotubes can be taken out for inspection or application when needed. Through the provided sampling cover plate 401, the sampling port 400 can be sealed when sampling is not carried out, avoiding air and moisture from entering the storage tank 100.

[0040] Furthermore, as Figure 1 shown, the sealing cover 600 is detachably connected to the top surface of the storage tank 100.

[0041] Through the provided sealing cover 600, the storage tank 100 can be sealed, preventing external air, moisture and impurities from entering the storage tank 100.

[0042] Furthermore, as Figure 2 shown, a fixing frame 300 is fixed to the bottom surface of the storage tank 100, a motor 301 is fixed to the top surface of the fixing frame 300, and the output end of the motor 301 is fixed to the bottom surface of the rotating pipe 102.

[0043] Through the provided fixing frame 300, the position of the motor 301 can be fixed. Through the provided motor 301, the rotating pipe 102 can rotate, and then the arc-shaped blade 103 stirs the carbon nanotubes, so that the air between the carbon nanotubes can be agitated, facilitating the inert gas discharged from the exhaust table hole 201 to move upward and push the air between the carbon nanotubes out, improving the air discharge effect.

[0044] Further, as Figure 2 shown, a support frame 700 is fixed at the bottom edge of the storage tank body 100.

[0045] By providing the support frame 700, the storage tank body 100 can be supported.

[0046] In summary: when exhausting the air in the storage tank body 100, first remove the sampling cover plate 401, then start the motor 301. The rotation of the motor 301 drives the rotation of the rotating tube 102, and the rotation of the rotating tube 102 drives the rotation of the arc-shaped blade 103. The arc-shaped blade 103 agitates the carbon nanotubes in the storage tank body 100, so that the gap between the carbon nanotubes can be increased. Then start the air pump 106. The air pump 106 injects inert gas into the rotating tube 102, and then enters the exhaust pipe 200, and finally discharges from the exhaust table hole 201. After the inert gas discharges from the exhaust table hole 201, it moves upward, pushing the air between the carbon nanotubes upward, so that the air between the carbon nanotubes and the air at the top of the storage tank body 100 are pushed out from the sampling port 400. After a period of time, turn off the air pump 106 and the motor 301 and cover the sampling cover plate 401 in the sampling port 400. The heat preservation layer 101 keeps the internal temperature of the storage tank body 100 stable, preventing the performance change of the carbon nanotubes caused by temperature change. The desiccant box 500 can absorb the moisture in the storage tank body 100 to keep the inside of the storage tank body 100 dry. The sealing cover 600 can seal the storage tank body 100 to prevent external air, moisture and impurities from entering the storage tank body 100. The sampling port 400 enables part of the carbon nanotubes to be taken out for inspection or application when needed. The sampling cover plate 401 can seal the sampling port 400 when sampling is not carried out, avoiding the entry of air and moisture into the storage tank body 100.

[0047] The heat preservation layer 101, the air pump 106, the motor 301, and the desiccant box 500 can all be purchased on the market, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
