Description

Technical Field

[0001] This utility model relates to the field of mold steel processing technology, and in particular to an oxidation reaction vessel for graphene production. Background Technology

[0002] Graphene is a single-layer thin film material composed of carbon atoms arranged in a honeycomb two-dimensional lattice with sp² hybrid orbitals. It has high thermal conductivity, strong electrical conductivity and excellent mechanical strength, and is a typical two-dimensional nanomaterial.

[0003] In the production of graphene oxide and its derivative composites, an oxidation reactor is usually required to complete the liquid-phase oxidation and exfoliation of graphite. The oxidation reactor for graphene production utilizes a corrosion-resistant lining and a temperature-controlled stirring system to precisely control the reaction temperature, disperse graphite particles, and promote the uniform insertion of oxidant between graphite layers, thereby achieving efficient oxidation and exfoliation into monolayer graphene oxide.

[0004] However, existing oxidation reactors for graphene production have the following shortcomings:

[0005] In the existing technology, the oxidation reactor used for graphene production is usually fixed and sealed to the top cover with a large number of bolts when operating in a long-term highly corrosive environment. However, when cleaning and maintaining the stirring blades, lining or residual slurry inside the reactor, this method is difficult to disassemble due to bolt corrosion and stripped threads. Moreover, bolt disassembly and assembly are time-consuming and labor-intensive, resulting in low maintenance efficiency and extended downtime.

[0006] Therefore, we propose an oxidation reactor for graphene production to address the problems mentioned above. Utility Model Content

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, as shown in the attached document Figure 1 - Appendix Figure 5 As shown, this utility model provides a technical solution: an oxidation reactor for graphene production, including a reactor body 1, a fixing plate 2 fixedly connected to the outer wall of the reactor body 1, a support column 3 fixedly connected to the top of the fixing plate 2, a telescopic column 4 movably inserted into the inner wall of the support column 3, a connecting block 5 fixedly connected to the top of the telescopic column 4, a sealing cover 6 fixedly connected to the outer wall of the connecting block 5, a hydraulic cylinder 7 fixedly connected to the top of the fixing plate 2, and the bottom of the connecting block 5 fixedly connected to the telescopic end of the hydraulic cylinder 7, a set of fixing blocks 8 fixedly installed on the top of the sealing cover 6, each of the fixing blocks 8 having a limit groove 9 on one side of its outer wall, an installation ring 10 fixedly connected to the outer wall of the reactor body 1, and a set of positioning blocks 11 fixedly installed on the outer wall of the installation ring 10. A set of fixed blocks 8 are movably inserted into the interior of a set of positioning blocks 11. A circular groove 12 is provided on the outer wall of the mounting ring 10. A circular slider 13 is slidably embedded in the inner wall of the circular groove 12. A movable ring 14 is fixedly connected to the outer wall of the circular slider 13. A set of arc-shaped limiting blocks 15 is fixedly connected to the top of the movable ring 14. The outer wall of the set of arc-shaped limiting blocks 15 is movably inserted into the interior of a set of limiting grooves 9. A set of toothed grooves 16 is provided on the outer wall of the movable ring 14. A gear 17 is meshed with the inner wall of a plurality of the toothed grooves 16. A first protective box 18 is fixedly connected to the outer wall of the reactor body 1. A self-locking motor 19 is fixedly connected to the inner wall of the first protective box 18. The output end of the self-locking motor 19 is fixedly inserted into the interior of the gear 17.

[0027] The overall effect of Embodiment 1 is as follows: During use, when it is necessary to disassemble the sealing cover 6 to clean and maintain its internal stirring components, lining, residual slurry, etc., the self-locking motor 19 is started first. Its output end drives the gear 17 to rotate. Through the meshing transmission between the gear 17 and the tooth groove 16, and the sliding cooperation between the circular slide groove 12 and the circular slider 13, the movable ring 14 is rotated and drives a set of arc-shaped limiting blocks 15 to move in a circular motion, so that the set of arc-shaped limiting blocks 15 disengages from the corresponding limiting groove 9, thereby releasing the fixed constraint of the sealing cover 6. Then, the hydraulic cylinder 7 is started, and its telescopic end drives the telescopic column 4 and the connecting block 5 to move upward, lifting the sealing cover 6, so that the stirring blades and the inner lining of the reactor body 1 are lifted. With residual materials exposed in the operating space, maintenance personnel can easily perform inspections, cleaning, and component replacements. This structure replaces traditional bolt disassembly with mechanized linkage, enabling convenient disassembly and assembly of the sealing cover 6, significantly improving maintenance efficiency and reducing the risk of damage to the sealing surface. Conversely, when the sealing cover 6 needs to be installed, the hydraulic cylinder 7 is activated to make the sealing cover 6 make tight contact with the top of the reactor body 1. Then, the self-locking motor 19 is driven to reverse, causing a set of arc-shaped limiting blocks 15 to be inserted into a set of limiting grooves 9, so that the sealing cover 6 and the mounting ring 10 form a tight tenon and mortise connection, ensuring the pressure-bearing sealing performance and structural stability of the sealing cover 6 during use, while avoiding the risk of deformation of the sealing surface caused by stress concentration in traditional bolt connections.

[0028] Example 2, as Figure 2-5 As shown, a valve 20 is installed at the output end of the reactor body 1. Two support seats 21 are fixedly connected to the inner wall of the reactor body 1. A conveying pipe 22 is fixedly connected between the outer walls of the two support seats 21. A discharge pipe 23 is opened on the outer wall of the conveying pipe 22. A discharge pipe 24 is opened on the outer wall of the conveying pipe 22. The output end of the reactor body 1 is fixedly connected to the input end of the discharge pipe 24. Two bearings 25 are fixedly inserted into the inner wall of the conveying pipe 22. A rotating shaft 26 is fixedly inserted between the interiors of the two bearings 25. A spiral blade 27 is fixedly sleeved on the outer wall of the rotating shaft 26. A second protective box 28 is fixedly connected to one side of the outer wall of the conveying pipe 22. A drive motor 29 is fixedly connected to the inner wall of the second protective box 28. The outer wall of the rotating shaft 26 is fixedly connected to the output end of the drive motor 29.

[0029] The effect achieved by the entire embodiment 2 is as follows: After the oxidation reaction inside the reactor body 1 is completed, when the discharge operation is required, the discharge valve 20 is opened and the drive motor 29 is started. The graphene oxide slurry inside the reactor body 1 falls into the conveying pipe 22 through the discharge pipe 24. At this time, the output end of the drive motor 29 drives the rotating shaft 26 and the spiral blade 27 to rotate. During the rotation of the spiral blade 27, the material is pushed to move downward to the feed pipe 23, so that the material after the reaction is discharged at a uniform speed, thereby avoiding the slurry from being unable to be discharged due to its own weight accumulation. At the same time, through the quantitative control function of the spiral conveyor, the discharge process is ensured to be stable and controllable, and the connection efficiency of subsequent processes is improved.

[0030] The working principle of the entire equipment is as follows: When it is necessary to disassemble the sealing cover 6 to clean or replace the internal stirring components, temperature sensors, flow guide baffles, etc. of the reactor, the self-locking motor 19 is started first. Through the meshing transmission of gear 17 and tooth groove 16 and the sliding guidance of circular slide groove 12 and circular slider 13, the moving ring 14 drives a set of arc-shaped limiting blocks 15 to move circumferentially, causing the set of arc-shaped limiting blocks 15 to disengage from the corresponding limiting groove 9, thereby releasing the fixed constraint of the sealing cover 6. Then, the hydraulic cylinder 7 is started to lift the sealing cover 6, exposing the stirring components, inner wall deposits and heating elements inside the reactor body 1 to the maintenance space, making it convenient for maintenance personnel to perform full inspection. The process involves surface inspection, component replacement, and residue cleaning. Conversely, when installing the sealing cover 6, the hydraulic cylinder 7 makes the sealing cover 6 fit with the installation ring 10, and then drives the self-locking motor 19 to reverse, causing a set of arc-shaped limiting blocks 15 to engage with a set of limiting grooves 9 to form a tight multi-point tenon and mortise connection, ensuring the structural stability and sealing reliability of the sealing cover 6 during use. During the discharge stage, the discharge valve 20 is opened and the drive motor 29 is started. The reaction products in the reactor body 1 flow into the conveying pipe 22 through the discharge pipe 24. The spiral blades 27 rotate and push the material to move downwards into the material pipe 23, so that the material after the reaction is discharged at a uniform speed, thereby avoiding material accumulation and blockage, and ensuring that the discharge process is smooth and controllable.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
