Description

Technical Field

[0001] The utility model relates to the technical field of nanotube production, and particularly relates to a flap-type nanotube production collector. Background Art

[0002] Carbon nanotubes are one-dimensional quantum materials with a special structure (radial dimension in the nanometer range, axial dimension in the micrometer range, and both ends of the tube are basically sealed). Carbon nanotubes are composed of several to dozens of coaxial circular tubes formed by carbon atoms arranged in a hexagonal pattern, and a fixed distance is maintained between layers. Carbon nanotubes are light in weight, have a perfect hexagonal structure connection, and have many abnormal mechanical, electrical, and chemical properties. In recent years, with the in-depth research on carbon nanotubes and nanomaterials, their broad application prospects have been continuously demonstrated.

[0003] The main preparation method of carbon nanotubes is chemical vapor deposition. Carbon nanotubes are light in weight, conductive, thermally conductive, and have a certain viscosity. In traditional processes, for carbon nanotubes grown on a silicon wafer substrate, carbon nanotubes are usually collected by manual scraping. Such a collection method not only requires a lot of manpower and time, but also the collected carbon nanotubes are easily entangled together, which affects subsequent use.

[0004] Based on this, the utility model designs a flap-type nanotube production collector to solve the above problems. Summary of the Utility Model

[0040] For better explaining the present utility model for easy understanding, the present utility model will be described in detail below with reference to the accompanying drawings through specific implementation modes.

[0041] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0042] In addition, in the present utility model, descriptions such as "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] In the present utility model, unless otherwise clearly specified and limited, terms such as "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; "connection" can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0044] See Figures 1 to 3 and Figures 5 to 7, the present utility model provides a flap - type nanotube production collector, which specifically includes a housing 1, a flap mechanism 2, a catalyst feeding mechanism 3, and an air inlet pipe 4. Among them, a discharge port is provided on the housing 1. Specifically, the housing 1 can preferably be a circular tube or a square tube, and can preferably be vertically arranged. The discharge port is located at the lower end of the housing 1, and the gas to be discharged can also flow through the discharge port. The flap mechanism 2 includes a flip - plate 21 and a drive assembly 23. The flip - plate 21 is installed in the housing 1 through a rotating shaft 22, and the drive assembly 23 can drive the flip - plate 21 to flip based on the rotating shaft 22. When the flip - plate 21 is in a horizontal state, the edge of the flip - plate 21 can block the inner wall of the housing 1. The flip - plate 21 can preferably be a circular plate or a square plate corresponding to the cross - sectional shape of the housing 1. The catalyst feeding mechanism 3 can penetrate the housing 1 to convey the catalyst onto the flip - plate 21 to facilitate the replenishment of the catalyst. The catalyst can accumulate on the flip - plate 21 to prepare nanotubes. The air inlet pipe 4 is connected to the inside of the housing 1 to introduce inert gas, reducing gas, and reaction carbon - source gas into the housing 1. Among them, the inert gas can be argon or helium, etc., and is preferably argon; the reducing gas is hydrogen, and the reaction carbon - source gas is any one of acetylene, methane, carbon monoxide, or ethylene, etc. In addition, a heating mechanism (not shown) for providing heat is provided outside the housing 1 to make the reaction temperature inside the housing 1 be between 600 and 900 °C, so that the preparation of nanotubes can proceed smoothly.

[0045] This device is applicable to the reaction and collection of nanotubes (such as carbon nanotubes). The reaction conditions are specifically as follows: the temperature is between 600 and 900 °C; hydrogen and acetylene are introduced into an argon atmosphere. After reaching the reaction conditions, the catalyst falls from the upper - end catalyst feeding mechanism 3 through the top wall of the housing 1 onto the flip - plate 21 and accumulates on the flip - plate 21. The air inlet pipe 4 directly provides the gas carbon - source into the housing 1. When in an argon environment, the gas carbon - source will crack into carbon atoms, and then deposit carbon nanotubes on the catalyst. After the reaction is completed, the drive assembly 23 can drive the flip - plate 21 to deflect based on the rotating shaft 22 so that the flip - plate 21 can flip. The carbon nanotubes on the flip - plate 21 naturally fall due to gravity and can be collected at the lower end of the housing 1. This collection method is very convenient and does not require too much manual intervention, thus greatly improving the preparation and collection efficiency of carbon nanotubes, which well meets the development needs of the nanotube industry. It should be noted that even if there is a small amount of carbon nanotubes remaining on the flip - plate 21, it will not affect the subsequent preparation of carbon nanotubes. After the carbon nanotubes fall, the drive assembly 23 can drive the flip - plate 21 to deflect in the reverse direction based on the rotating shaft 22 so that the flip - plate 21 can return to the horizontal state again, and the catalyst powder falling from above continues to accumulate on the flip - plate 21, and carbon nanotubes can be continuously prepared.

[0046] In a preferred embodiment, as Figure 4As shown in the figure, the driving component 23 includes a hinge seat 231, a push rod 233 and a slide rail 234. The hinge seat 231 is arranged on the turning plate 21. The first end of the push rod 233 is fixedly provided with a fixed block 232 with a chute 2321. The second end of the push rod 233 can penetrate through the housing 1 and be connected to an external motor assembly. The hinge shaft 2311 of the hinge seat 231 can slide in the chute 2321; the slide rail 234 can limit the push rod 233 to perform linear motion, and the sliding direction of the hinge shaft 2311 in the chute 2321 is perpendicular to the linear motion direction of the push rod 233. The slide rail 234 is sleeved on the push rod 233. Among them, the slide rail 234 can be installed on the inner wall of the housing 1 through an auxiliary bracket (not shown) to limit and guide the running direction of the push rod 233. The second end of the push rod 233 can penetrate through the housing 1 and be connected to an external motor assembly (not shown). The motor assembly can include a motor and a gear-rack set, or include a motor and a worm and worm gear set, so as to be able to drive the push rod 233 to perform linear reciprocating motion. The bottom of the housing 1 and the push rod 233 are in dynamic seal, which can not only maintain the sealing effect but also does not interfere with the linear motion of the push rod 233. When the push rod 233 moves up and down reciprocally in the vertical direction under the action of the motor assembly, the hinge shaft 2311 can slide in the chute 2321 to drive the turning plate 21 to deflect based on the rotating shaft 22. For example, referring to Figure 3 , when the push rod 233 moves upward along the slide rail 234, it will drive the fixed block 232 to move upward, and then drive the hinge shaft 2311 on the hinge seat 231 to move upward and move horizontally in the chute 2321, so as to realize the turning of the turning plate 21 based on the rotating shaft 22.

[0047] In addition, it should be noted that in other embodiments, the driving component 23 can also adopt other similar structures as long as it can realize the turning action of the turning plate 21. Referring to Figure 8 and Figure 9 , the end of the rotating shaft 22 that penetrates through the housing 1 and extends outside the housing 1 is an extension end, and a coupling 235 is arranged on the extension end. The coupling 235 can be connected to an external motor assembly. Among them, the side wall of the housing 1 and the rotating shaft 22 are in dynamic seal, which can not only ensure the sealing effect but also does not affect the rotation of the rotating shaft 22. The motor assembly can be a servo motor to control the state of the turning plate 21 according to actual working requirements.

[0048] In a preferred embodiment, the flip-type carbon nanotube production and collection device further includes a collection box 5. The collection box 5 is connected to the discharge port at the lower end of the housing 1. The collection box 5 can collect the dropped carbon nanotubes. An air outlet pipe 51 is opened on the collection box 5. There is only one air outlet pipe 51. Argon gas is continuously introduced from the air inlet pipe 4, and the excess gas is discharged from the air outlet pipe 51 to ensure a stable air pressure in the argon gas atmosphere.

[0049] For the convenience of arranging each structure, an inclined connecting pipe 11 (see Figures 1 to 3 ) or a vertical connecting pipe 11a (see Figures 5 to 7 ) is formed at the discharge port of the housing 1. The collection box 5 is docked with the lower end of the connecting pipe 11, and an air outlet pipe 51 is provided at the top of the collection box 5. Among them, flange edges can be formed at the docking positions of the collection box 5 and the connecting pipe 11, and the collection box 5 and the connecting pipe 11 are detachably connected by a clamp or a plurality of buckles. Specifically, it can be that the clamp surrounds and wraps the butted flange edge, or it can also be that a plurality of buckles on the collection box 5 can buckle the flange edge on the connecting pipe 11, so that the collection box 5 and the connecting pipe 11 are detachably connected, thereby facilitating the replacement of the collection box 5.

[0050] Furthermore, see Figure 1 , the end of the air inlet pipe 4 is docked with the air inlet in the middle of the housing 1; or, see Figure 2 and Figure 3 , the air inlet pipe 4a penetrates through the air inlet in the upper part of the housing 1 and extends along the inner wall of the housing 1 to the middle of the housing 1, so that the air outlet position of the air inlet pipe 4 is close to the catalyst accumulated on the turning plate 21, thereby being able to improve the production efficiency of carbon nanotubes. Among them, in actual production, different arrangement methods of the air inlet pipe 4 can be selected according to requirements.

[0051] In addition, the catalyst feeding mechanism 3 includes a hopper 31 and a material guiding pipe 32. The hopper 31 is located outside the housing 1, and the bottom of the hopper 31 is connected to the material guiding pipe 32. The material guiding pipe 32 penetrates through the top wall of the housing 1 to be able to convey the catalyst onto the turning plate 21 to meet the production requirements of carbon nanotubes.

[0052] It should be understood that the above description of the specific embodiments of the present invention is only for explaining the technical route and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, but the present invention is not limited to the above specific embodiments.
