[0002] Graphene is a two-dimensional carbon material with a single atomic layer thickness. Due to its excellent mechanical properties, high electrical conductivity, high thermal conductivity and electron mobility, it has broad application prospects in the fields of integrated circuits, battery energy, electrode materials, etc.

[0003] However, the preparation of graphene has always been the key technology that restricts the development of graphene. Most of the equipment for preparing graphene on the market currently have a series of physical and chemical methods, but there are problems such as slow preparation, small preparation amount, unstable performance, etc. The preparation equipment and production process are relatively complex, with poor uniformity, high preparation cost and high price, which is difficult to meet the large-scale market demand.

[0004] One of the graphene production methods is to place the carbon black raw material in a quartz tube, place the quartz tube on a fixed clamping device on a work platform, and then pressurize and energize the metal rods inserted at both ends of the quartz tube to achieve the conversion of the carbon source into graphene through high voltage and high current. However, most of the fixed clamping devices in the prior art cannot apply sufficient and appropriate clamping force to the quartz tube, resulting in the quartz tube being offset or even falling off due to insufficient clamping force or the quartz tube being broken due to excessive clamping force during the pressurization process, which ultimately leads to the failure of the graphene preparation process.

[0005] In view of the above problems existing in the prior art, it is urgently necessary to design a clamping assembly for graphene preparation so as to more firmly clamp the reaction container containing carbon black, thereby solving the above problems. Summary of the invention

In order to make the purpose, technical solution and advantages of the present application clearer, the implementation method of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0034] The present application embodiment provides a clamping assembly for graphene preparation, see Figure 1 to Figure 2, used for clamping a reaction container filled with carbon black raw materials, including a fixed base 10, a first clamping member 30, a second clamping member 20 and a plurality of buckle components 40, wherein the first clamping member 30 is arranged on the fixed base 10, a first receiving groove is provided on one side of the first clamping member 30, the second clamping member 20 is rotatably arranged on the fixed base 10, and can rotate close to or away from the first clamping member 30 with the fixed base 10 as an axis, a second receiving groove is provided on the second clamping member 20, and the second receiving groove is arranged opposite to the first receiving groove, when the first clamping member 30 and the second clamping member 20 are sufficiently close to each other, the first receiving groove and the second receiving groove are enclosed to form a clamping groove 50 adapted to the reaction container, the clamping groove 50 is used to clamp and fix the reaction container, and the buckle component 40 is used to connect the first clamping member 30 and the second clamping member 20, and enable the first receiving groove and the second receiving groove to remain closed.

[0035] Specifically, the graphene preparation process generally includes a pressurization step, and the pressurization method usually includes squeezing the metal plugs at both ends of the reaction container from the two ends of the reaction container to the carbon black raw material in the reaction container. During this process, the stability of the reaction container needs to be maintained to avoid the situation where the reaction container is damaged due to position displacement. Therefore, the clamping groove 50 formed on the clamping assembly is usually consistent with the moving direction of the pressure-applying device on both sides of the graphite preparation equipment. The first clamping member 30 is fixed and the second clamping member 20 is rotated to change the opening and closing state of the clamping assembly, so as to effectively reduce the position displacement caused by the movement of too many parts of the clamping assembly. In addition, the first receiving groove and the second receiving groove are respectively opened to facilitate the placement of the reaction container, thereby effectively ensuring the stability of the reaction container 70 during the actual pressurization operation, thereby effectively ensuring the stability of the preparation process.

[0036] It should be pointed out that, generally speaking, the reaction container is a tubular container. Therefore, the clamping groove 50 may correspond to a circular contour or an elliptical contour. The specific situation depends on the actual situation and is not limited here. In addition, when the first receiving groove and the second receiving groove just divide the clamping groove 50 equally, the placement operation of the reaction container is relatively most convenient.

[0037] In some embodiments, see Figure 1 to Figure 2 The buckle assembly 40 includes a hook 41 and a fixing seat 42. The fixing seat 42 is provided with a strip groove corresponding to the hook 41 so that the hook 41 can be buckled with the fixing seat 42. At least two first fixed ends are provided on the fixing seat 42. The two first fixed ends are respectively fixed to the same surface of the first clamping member 30 and the two ends corresponding to be away from the clamping groove 50. At least two second fixed ends are provided on the hook 41. The two second fixed ends are respectively fixed to the same surface of the second clamping member 20 and the two ends corresponding to be away from the clamping groove 50.

[0038] Specifically, the hook member 41 includes a fixing plate and a U-shaped hook 43, a back-pull structure is provided on the fixing plate, the U-shaped hook 43 is rotatably provided on the back-pull structure, and a strip groove is provided on the fixing seat 42. When the U-shaped hook 43 is rotated to a preset position, it can be correspondingly inserted into the strip groove, and then the back-pull structure is operated to make the U-shaped hook 43 stably in the strip groove, that is, the corresponding connection between the hook member 41 and the fixing seat 42 is realized, which has the advantages of simple structure and convenient operation. The other two first fixed ends are respectively correspondingly provided on the same surface of the first clamping member 30 and are away from each other. The two ends of the clamping groove 50 allow the fixing seat 42 to cover the same surface of the first clamping member 30 to a large extent, thereby effectively expanding the contact area between the fixing seat 42 and the first clamping member 30, and effectively strengthening the connection effect between the fixing seat 42 and the first clamping member 30. Similarly, it can be known that the second fixed ends are respectively fixed on the same surface of the second clamping member 20 and the two ends away from the clamping groove 50, which can also effectively strengthen the connection effect between the hook 41 and the second clamping member 20, providing a strong guarantee for the buckle assembly 40 to achieve a stable connection effect.

[0039] It should be pointed out that the hook 41 can also be installed on the first clamping member 30, and the corresponding fixing plate can be installed on the second clamping member 20. The specific situation can be determined according to actual needs and is not limited here.

[0040] In some embodiments, see Figure 1 and Figure 2 A rotation groove 11 is formed on the fixed base 10 , and the second clamping member 20 is rotatably disposed in the rotation groove 11 via a rotation axis, and the rotation axis is parallel to the extending direction of the clamping groove 50 .

[0041] Specifically, rotation holes are opened on the support walls on both sides of the rotating groove 11, and the rotating shaft passes through the second clamping member 20. At the same time, the two ends of the rotating shaft are correspondingly inserted into the two rotation holes, so that the second clamping member 20 can be rotatably set in the rotating groove 11. In addition, when the pressurization operation is performed, that is, when the carbon black raw material in the reaction container is squeezed, the two support arms can play an additional supporting and limiting role, further enhancing the stability effect of the clamping assembly.

[0042] In some embodiments, see Figure 1 and Figure 2 The second clamping member 20 is provided with an observation window 21 , which is directly opposite to and connected to the clamping groove 50 .

[0043] Specifically, by providing the observation window 21, the installation status of the reaction container can be directly observed so that the reaction container can be adjusted in time. In addition, the real-time situation in the reaction container during the graphene preparation process can be observed, thereby effectively ensuring the normal progress of the preparation process.

[0044] It should be noted that an observation window 21 may also be provided on the first clamping member 30 to enable real-time observation and recording of the reaction conditions in the reaction container during the graphene preparation process from another direction.

[0045] In some embodiments, see Figure 1 and Figure 2 A hand-held platform 44 is provided on one end of the second clamping member 20 away from the fixed base 10 , and the hand-held platform 44 extends in a direction away from the first clamping member 30 .

[0046] Specifically, a handheld platform 44 is provided to facilitate workers to rotate the second clamping member 20 more conveniently and effortlessly. In addition, the handheld platform 44 is provided at one end of the second clamping member 20 away from the fixed base 10, so that workers can operate more effortlessly, thereby effectively improving overall work efficiency.

[0047] In some embodiments, see Figure 1 and Figure 2 The number of buckle assemblies 40 is one group, the first fixed ends are fixedly arranged on a side of the first clamping member 30 away from the fixed base 10, and the second fixed ends are fixedly arranged on a side of the handheld platform 44 away from the fixed base 10.

[0048] Specifically, the buckle assembly 40 is disposed on a side of the first clamping member 30 away from the fixed base 10 , so that personnel can operate the buckle assembly 40 more conveniently and the clamping stability of the clamping assembly can be effectively enhanced.

[0049] It should be pointed out that the buckle components 40 can also be three groups, and the other two groups are respectively arranged on the two side sides of the two openings of the clamping groove 50 on the clamping component. By setting three groups of buckle components 40, the clamping effect of the clamping component can be further enhanced. The specific number of buckle components 40 can be determined according to actual needs.

[0050] An embodiment of the present application further provides a graphene preparation device, comprising a working platform, on which is disposed a clamping assembly for graphene preparation in any of the above embodiments.

[0051] Specifically, a graphene preparation device provided with the clamping assembly for graphene preparation described in any of the above embodiments has a stronger clamping effect on the reaction container, and can provide better guarantee for the normal progress of the graphene preparation process.

[0052] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and modifications of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and modifications.
