Description

Technical Field

[0001] The present invention relates to the technical field of carbon aerogels, and specifically to a one-pot reaction processing device for carbon aerogels. Background Art

[0002] Carbon aerogels have excellent electrical conductivity, specific surface area, and pore structure, showing extensive application potential in multiple high-tech fields such as energy storage, catalysis, and adsorption. During their preparation process, one-pot reaction processing devices have gradually become important devices for preparing carbon aerogels due to advantages such as simplified process flow, lower energy consumption, and higher reaction efficiency. Such devices can usually continuously complete multiple steps such as precursor mixing, sol-gel conversion, drying, and carbonization in a single reaction vessel, avoiding energy waste and material transfer losses in traditional step-by-step operations, and helping to improve the consistency and preparation efficiency of products.

[0003] Existing one-pot reaction processing devices for carbon aerogels usually adopt a reaction kettle structure, combined with a temperature and pressure control system, and a stirring device to mix and react raw materials. The device is generally equipped with multiple temperature control zones and an inert gas protection system inside, which can realize an integrated processing process from precursor mixing, sol-gel reaction to drying and carbonization. However, there is generally a lack of an effective screening and control link for the particle size of raw materials before the reaction in the existing technology, resulting in raw materials with inconsistent particle sizes entering the reaction system, which easily causes problems such as particle blockage or equipment wear.

[0040] Among them, the crushing component includes a crushing box 3 and two crushing rollers 11. The legs of the crushing box 3 are fixedly connected to the top of the fixed frame 2. The side walls of the crushing rollers 11 are rotatably connected inside the crushing box 3. A transmission gear 12 is fixedly connected to one side of the crushing box 3.

The output end of the motor 14 is fixedly connected to one end of the crushing roller 11 on one side. By driving the crushing roller 11 to rotate with the motor 14, the extrusion crushing of the material is realized;

[0041] The screening component includes a screening plate 4. The screening plate 4 is arranged on top of the crushing box 3 to block materials with too large particle sizes and prevent them from directly entering the crushing component, causing equipment blockage or damage. A rotating block 6 is fixedly connected to the side wall of the screening plate 4, and a fixed frame 7 is fixedly connected to the side wall of the crushing box 3.

The conveying pipe 15 is communicated with the crushing box 3. The material crushed by the crushing mechanism can directly fall into the inside of the conveying pipe 15. One end of the rotating shaft 16 penetrates through the side wall of the conveying pipe 15 and is fixedly connected with a first sprocket 18. The output end of the first motor 14 is fixedly connected with a second sprocket 19. A chain 20 is arranged between the first sprocket 18 and the second sprocket 19. On the basis of driving the crushing roller 11, the first motor 14 can also drive the first sprocket 18 and, with the cooperation of the chain 20, synchronously drive the second sprocket 19 to rotate, realizing integrated power transmission, so that the material is propelled to the feeding pipe under the action of screw conveying and enters the reaction kettle 1 to realize automatic continuous feeding.

[0043] Please refer to the attached Figure 6 - attached Figure 8The inner wall of the reactor 1 is provided with a heating wire 23, and the side wall of the reactor 1 is provided with a controller 24. The controller 24 is electrically connected to the heating wire 23. The heating wire 23 is used to provide a uniform heat source with high heating efficiency and fast response. The reaction temperature can be accurately controlled according to the parameters set by the controller 24. The temperature is usually 40°C-90°C, inducing a cross-linking reaction between the precursor molecules. As the reaction time advances, the system gradually transforms into a wet gel with a three-dimensional network structure. The continuous rotation of the mixing mechanism ensures a uniform structure and prevents precipitation and phase separation, thereby optimizing the integrity of the gel network. After the gel is formed, it is further heated to a high temperature. The temperature is set at 400 °C and an inert gas such as nitrogen or a slightly positive pressure air flow is introduced into the air inlet 25 to achieve slow evaporation of the solvent. The dried wet gel is heated to 600-1200 °C by the electric heating wire 23 under a controlled atmosphere (such as nitrogen or argon) for carbonization. The carbonization process adopts an adjustable heating rate (such as 2-5 °C / min) to control the temperature of the reactor 1 to rise evenly, so that the organic components are thermally cracked into carbonaceous materials while retaining their original three-dimensional network skeleton, and finally converted into a carbon aerogel with a complete structure. The mixing mechanism includes a connecting rod 32 and a stirring blade 33. The stirring blade 33 is responsible for rotating and revolving the reactants. The reactor 1 is provided with a detachable reactor cover 26 on the top, a motor 29 is fixedly connected to the top of the reactor cover 26, an output end of the motor 29 passes through the side wall of the reactor cover 26 and is fixedly connected to a driving wheel 31, a planetary gear set is arranged at the bottom of the reactor cover 26, the planetary gear set includes a built-in gear ring frame 27, a driving wheel 31 and a driven wheel 34, a top support rod of the built-in gear ring frame 27 is fixedly connected to the lower surface of the reactor cover 26, the driving wheel 31 is fixedly connected to the side wall of the support rod 30, the driven wheel 34 is fixedly connected to the side wall of the connecting rod 32, the driving wheel 31 is meshed with the driven wheel 34, and the driven wheel 34 is meshed with the built-in gear ring frame 27. The connecting rod 32 is arranged in the inner cavity of the reactor 1, the top wall of the stirring blade 33 is fixedly connected to the bottom of the stirring blade 33, the driven wheel 34 is installed on the connecting rod 32 and meshes with the driving wheel 31 and the built-in gear ring frame 27 to realize the revolution and rotation of the connecting rod 32 and the stirring blade 33, and the multiple stirring blades 33 move synchronously. The rotational motion ensures that the component materials are fully mixed before the reaction and optimizes the gel structure. An annular groove 28 is opened inside the reactor cover 26, and a limiting block 35 is fixedly connected to the top of the connecting rod 32. The limiting block 35 is arranged inside the annular groove 28 to play a guiding and limiting role, thereby ensuring that the stirring motion trajectory is stable and consistent.

[0044] Working principle: When using this device for work, first send the raw materials into the interior of the crushing box 3 through the screening plate 4. The screening plate 4 will block large pieces of materials to prevent them from entering the device and damaging the device components. The blocked materials will stay on the top of the screening plate 4. At this time, by starting the hydraulic rod 10, under the action of the connecting block 9, it will gradually deflect itself and push the screening plate 4 upward, causing the screening plate 4 to deflect around the fixed frame 7 and pour the materials staying on the top downward, so that they fall into the storage box arranged at the bottom through the guiding plate 21 for reuse after being broken. After the materials fall into the interior of the crushing box 3, start the first motor 14 to drive the connected crushing roller 11 to rotate. Under the meshing action of the transmission gears 12, drive the crushing roller 11 on the other side to rotate and engage with each other, achieving the effect of crushing the material particles into fine particles. The crushed materials continue to fall downward into the interior of the conveying pipe 15. While driving the crushing roller 11 to rotate, the first motor 14 will also drive the second sprocket 19 to rotate. Under the action of the chain 20, synchronously drive the first sprocket 18 to rotate, and then drive the rotating shaft 16 to rotate. At this time, the auger blade 17 will push the materials in the conveying pipe 15 forward and enter the interior of the reaction kettle 1 through the ball shaft 22. After the material filling is completed, close the ball shaft 22 to ensure the sealing of the device. Then start the second motor 29 to drive the driving wheel 31 to rotate, drive the driven wheel 34 to rotate, and make the driven wheel 34 move along the internal tooth ring of the built-in tooth ring frame 27, thereby driving the connecting rod 32 to revolve around the support rod 30 while rotating itself, and achieving the effect of fully stirring the materials through the stirring blade 33. After the stirring is completed, control the heating wire 23 to heat the interior of the reaction kettle 1 through the controller 24, so that the raw materials mixed inside gradually gel and take shape, and send inert gas into the interior of the reaction kettle 1 through the inlet pipe 25, thereby performing high-temperature carbonization treatment on the raw materials.
