Description

Technical Field

[0001] This invention relates to the field of carbon nanotube corner production technology, and more specifically, to a storage device for carbon nanotube corner production. Background Technology

[0002] Carbon nanohorns are a new type of carbon nanomaterial that has emerged in recent years after carbon nanotubes. A single carbon nanohorn has a diameter of 2-5 nm, a closed conical structure at one end and an open end at the other, and a length of 10-20 nm. In the production of carbon nanohorns, carbon vapor is generated by irradiating the side of a graphite rod with a laser beam, and the cooled carbon vapor is then recovered to obtain carbon nanohorns. This is one of the methods for obtaining carbon nanohorns.

[0003] A search revealed a Chinese patent (publication number: CN214085834U) that discloses a raw material storage device for nanomaterial research and development. The patent includes a cabinet, with rollers fixedly connected to the four corners of the bottom side of the cabinet. Slide rails are fixedly connected to the lower left and right sides of the inner wall of the cabinet. A sliding shelf mechanism is slidably connected to the upper side of the slide rails near the inner wall of the cabinet. A desiccant holder is fixedly connected to the lower middle part of the sliding shelf mechanism. A partition is hooped to the upper inner wall of the cabinet. An insulation layer is fixedly connected to the inner wall of the cabinet and the lower wall of the partition. A humid and hot air outlet pipe is fixedly connected to the left side of the partition.

[0004] When collecting carbon nanoparticles, the temperature of the carbon vapor needs to be controlled, and backflow of carbon vapor should be avoided to prevent poor collection quality. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a storage device for the production of carbon nanotubes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a storage device for the production of carbon nanotubes, comprising a connecting frame and multiple collection tanks, wherein an air supply mechanism is installed on the top of the connecting frame;

[0007] The bottom of the connecting frame has multiple connection ports, and a locking port is installed on the lower side of the lower surface of the connecting frame near each connection port.

[0008] The tops of all of the collection containers are embedded inside the locking port, and the top of the collection container is provided with an opening communicating with the connection port;

[0009] At least one set of cooling pipes is installed on the side of the connecting frame, and one end of each cooling pipe is connected to a one-way connecting pipe.

[0010] The one-way connecting pipe has multiple one-way connecting pipes inside, and the air inlets of the multiple one-way connecting pipes are all connected to the cooling pipe.

[0011] The cooling pipe has a cooling channel inside, and a cooling medium tank is provided inside the cooling pipe near the outside of the cooling channel to adjust the temperature inside the cooling channel.

[0012] An air inlet block and an air outlet block are respectively installed at both ends of the upper surface of the cooling pipe, and the air inlet block and the air outlet block are respectively connected to the two ends of the cooling pipe with smaller diameter and larger diameter.

[0013] Furthermore, the one-way connecting pipe has a frustum structure, and the end of the one-way connecting pipe with a smaller diameter faces the cooling pipe;

[0014] The diameter ratio of the two ends of the one-way connecting pipe is 1:0.2-0.1 to prevent carbon vapor from flowing back into the pipe body after passing through it.

[0015] Furthermore, the cooling medium tank has a spiral structure, and the diameter of the cooling medium tank increases proportionally from the unidirectional connecting pipe to the connecting frame;

[0016] As carbon vapor moves along the cooling channel, the rate of heat loss increases in the positive direction.

[0017] Furthermore, one end of the cooling pipe is equipped with an inclined air outlet pipe extending into the interior of the connecting frame;

[0018] The outlet of the inclined air duct is inclined downward, and the angle between it and the vertical direction is 50-75°.

[0019] Furthermore, the air outlet of the inclined air outlet pipe covers the upper side of each collection tank, and multiple connecting holes are opened inside the inclined air outlet pipe.

[0020] Furthermore, each of the collection tanks and the connection ports is equipped with a connecting valve; when replacing a collection tank, the corresponding connecting valve is closed to avoid carbon vapor leakage during replacement.

[0021] Furthermore, the inner wall of the locking port is provided with an inclined surface, and at least one set of electromagnetic components is installed on the side of the locking port near the inclined surface.

[0022] The top of the collection tank is provided with a side wall that fits against the inclined surface, and a magnetic component corresponding to the electromagnetic component is installed on the side wall of the top of the collection tank.

[0023] The number and distribution of magnetic components correspond to those of electromagnetic components.

[0024] Furthermore, at least one set of first positioning modules is installed at the inner top of the locking port, and a second positioning module corresponding to the first positioning module is installed at the top of the collection tank;

[0025] When the first positioning module and the second positioning module are adapted, the electromagnetic component is activated, and the magnetic component is used to adsorb and reinforce the collection tank.

[0026] Furthermore, the air supply mechanism has an air outlet on its side, and the air outlet has the following usage methods:

[0027] The air outlet is equipped with a filter, and the gas in the connecting frame and each collection tank overflows by self-flow.

[0028] The air outlet is connected to the air pump, and the gas in the connecting frame and each collection tank is transported by pumping.

[0029] Furthermore, the method of using the storage device includes the following steps:

[0030] Step 1: Install each collection container into its corresponding locking slot in sequence;

[0031] Step 2: Align the second positioning module on the top of each collection tank with the first positioning module in the locking port, activate the electromagnetic component in the corresponding locking port, and connect the collection tank to the locking port;

[0032] Step 3: Carbon vapor is transported through the various pipes in the one-way connecting pipe to the cooling channel in the cooling pipe;

[0033] Step 4: After the carbon vapor is cooled in the cooling medium tank, it is transported to the connecting frame;

[0034] Step 5: Inert gas is intermittently introduced into the connecting frame through the air supply mechanism, and the cooled carbon vapor is blown to each collection tank for recovery;

[0035] Step Six: When replacing the collection tank, close the corresponding connection port and electromagnetic components, remove the replacement collection tank, and assemble the new collection tank with the connecting frame by repeating the process in Step Two.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] In this application, the storage device is equipped with a one-way connecting pipe and a cooling pipe at the feeding section. The one-way connecting pipe can prevent backflow during carbon vapor recovery. At the same time, the cooling pipe can gradually reduce the temperature along the movement path of the carbon vapor, avoiding the problem of carbon vapor forming too quickly due to excessive temperature drop, which would lead to a decrease in conveying quality.

[0038] On the other hand, an air supply mechanism is provided on the upper side of the connecting frame. After the cooled carbon vapor enters the connecting frame, it can be blown into each collection tank, thereby quickly guiding the carbon vapor to the collection tank for recycling.

[0045] Reference Figures 1 to 5 As shown, a storage device for the production of carbon nanotubes includes a connecting frame 1 and multiple collection tanks 6. An air supply mechanism 2 is installed on the top of the connecting frame 1, and the air inlet of the air supply mechanism 2 is used to connect to an inert gas supply device.

[0046] The bottom of the connecting frame 1 has multiple connection ports 4, and the lower surface of the connecting frame 1 near each connection port 4 is equipped with a locking port 3.

[0047] The tops of multiple collection tanks 6 are all embedded inside the locking port 3, and the top of the collection tank 6 is provided with an opening communicating with the connection port 4;

[0048] At least one set of cooling pipes 7 are installed on the side of the connecting frame 1, and a one-way connecting pipe 8 is installed at one end of the cooling pipe 7;

[0049] Multiple one-way connecting pipes 8 are provided inside the one-way connecting pipe 8, and the air inlets of the multiple one-way connecting pipes 8 are all connected to the cooling pipe 7.

[0050] The cooling pipe 7 has a cooling channel 75 inside, and a cooling medium tank 71 is provided inside the cooling pipe 7 near the outside of the cooling channel 75 to adjust the temperature inside the cooling channel 75.

[0051] An air inlet block 72 and an air outlet block 73 are respectively installed at both ends of the upper surface of the cooling pipe 7. The air inlet block 72 and the air outlet block 73 are respectively connected to the two ends of the cooling pipe 7 with smaller and larger diameters.

[0052] An air outlet is provided on the side of the air supply mechanism 2. The air outlet is used in this embodiment as follows:

[0053] The air outlet is equipped with a filter, and the gas in the connecting frame 1 and each collection tank 6 overflows by self-flow.

[0054] Reference Figure 2 As shown, the one-way connecting pipe 8 has a frustum structure, and the end of the one-way connecting pipe 8 with a smaller diameter faces the cooling pipe 7.

[0055] The diameter ratio of the two ends of the one-way connecting pipe 8 is 1:0.2-0.1, preferably 0.12, to prevent carbon vapor from flowing back into the interior of the pipe body 81 after passing through it.

[0056] Reference Figure 3 As shown, the cooling medium tank 71 has a spiral structure, and the diameter of the cooling medium tank 71 increases proportionally from the one-way connecting pipe 8 to the connecting frame 1.

[0057] As the carbon vapor moves along the cooling channel 75, the rate of heat loss increases in the positive direction.

[0058] Reference Figure 4 As shown, one end of the cooling pipe 7 is equipped with an inclined air outlet pipe 74 that extends into the interior of the connecting frame 1;

[0059] The air outlet of the inclined air outlet 74 is inclined downward, and the angle between it and the vertical direction is 50-75°, preferably 72°.

[0060] Furthermore, the air outlet of the inclined air outlet pipe 74 covers the upper side of each collection tank 6, and multiple connecting holes 76 are opened inside the inclined air outlet pipe 74.

[0061] After carbon vapor enters the connecting frame 1 through the inclined air outlet duct 74, it will flow downwards due to the force and gravity of leaving the inclined air outlet duct 74.

[0062] Each collection tank 6 is equipped with a connecting valve 5 at the connection point between it and the connection port 4. When replacing the collection tank 6, the corresponding connecting valve 5 should be closed to avoid carbon vapor leakage during replacement.

[0063] Reference Figure 5 As shown, the inner wall of the locking port 3 is provided with an inclined surface 31, and at least one set of electromagnetic components 32 are installed on the side of the locking port 3 near the inclined surface 31.

[0064] The top of the collection tank 6 is provided with a side wall that fits against the inclined surface 31, and a magnetic component 61 corresponding to the electromagnetic component 32 is installed on the side wall of the top of the collection tank 6.

[0065] The number and distribution of magnetic components 61 correspond to those of electromagnetic components 32.

[0066] At least one set of first positioning modules 33 is installed at the top of the inside of the locking port 3, and a second positioning module 62 corresponding to the first positioning module 33 is installed at the top of the collection tank 6;

[0067] When the first positioning module 33 is adapted to the second positioning module 62, the electromagnetic component 32 is activated, and the magnetic component 61 adsorbs and reinforces the collection tank 6.

[0068] Working principle:

[0069] Install each collection tank 6 into the corresponding locking port 3 in sequence. During the initial installation, the time interval between each group of collection tanks 6 is 20 minutes.

[0070] And after the first set of collection tanks 6 is installed, the storage device starts to work to recover carbon vapor;

[0071] During installation, the side wall of the top of the collection tank 6 is attached to the inclined surface 31 of the locking port 3. Then, the collection tank 6 is rotated until the second positioning module 62 on the top of the collection tank 6 is aligned with the first positioning module 33 in the corresponding locking port 3. The electromagnetic component 32 in the corresponding locking port 3 is activated to connect the collection tank 6 to the locking port 3. After connection, the corresponding connecting valve 5 is opened to connect the collection tank 6 to the connecting frame 1.

[0072] Carbon vapor is transported to the cooling channel 75 in the cooling pipe 7 through the various pipes 81 in the one-way connecting pipe 8. When the carbon vapor moves along the pipe 81, the width of its movement path decreases. After flowing out from the end of the pipe 81 with the smaller diameter, it can avoid the problem of backflow. In addition, the flow rate increases and the contact area with the cooling medium tank 71 increases.

[0073] The cooling medium enters the cooling medium tank 71 through the air inlet block 72 and is discharged along the air outlet block 73. The diameter of the cooling medium tank 71 increases along the horizontal direction of the cooling channel 75. When the carbon vapor passes through the cooling channel 75, it is cooled by the cooling medium tank 71. The cooling rate increases with the length of the cooling channel 75. Finally, it is transported to the connecting frame 1 through the inclined air outlet pipe 74.

[0074] Inert gas is intermittently introduced into the connecting frame 1 through the air supply mechanism 2, and the cooled carbon vapor is blown to each collection tank 6 for recovery. Inert gas is delivered from the air supply mechanism 2 to the connecting frame 1 every 30 seconds, each time lasting for 3 seconds, with a flow rate of 700 ml / min, and the carbon vapor is guided to each collection tank 6 through the through-hole 76.

[0075] When replacing the collection tank 6, close the corresponding connection port 4 and electromagnetic component 32, remove the replacement collection tank 6, and assemble the new collection tank 6 with the connecting frame 1.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
