[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Referring to Figures 1-4, one embodiment of this utility model is provided: a raw material recovery device for carbon aerogel preparation, including a cylinder 1, which provides space for the distillation and separation of carbon aerogel raw materials. A material tank 15 is fixedly connected to one side of the top of the cylinder 1 for storing waste materials in the preparation of carbon aerogel. A steam pipe 18 is fixedly connected to one side of the top of the cylinder 1 for outputting steam generated during distillation, so as to separate the target components while avoiding excessive pressure. A geared motor 7 is fixedly installed in the middle of the top of the cylinder 1. The output end of the geared motor 7 passes through the inner wall of the cylinder 1 and is fixedly connected to a vertical shaft 8. After the geared motor 7 is started, it can drive the vertical shaft 8 to rotate. Stirring blades 9 are fixedly connected to the middle and bottom of the vertical shaft 8. The rotating stirring blades 9 can agitate the solvent to increase the heating efficiency during distillation. A cleaning component is installed on the surface of the vertical shaft 8. With the rotation of the vertical shaft 8, the cleaning component can clean the inner wall of the cylinder 1. A spiral tube 17 is fixedly connected to the inner wall of the material tank 15. The spiral tube 17 can increase the flow area and flow time of the medium.

[0032] Referring to Figures 2 and 3, the cleaning assembly includes two support rods 10, two grooves 13, two spring pieces 14, two connecting rods 11, and a brush 12. The two support rods 10 are fixedly connected to the top and bottom of the vertical shaft 8, respectively. A groove 13 is provided at one end of each of the two support rods 10. Spring pieces 14 are fixedly connected to the inner walls of the two grooves 13. Support rods 10 are fixedly connected to one end of each of the two spring pieces 14. Brushes 12 are fixedly connected to one end of each of the two support rods 10. Under the action of elastic force, the spring pieces 14 can push the connecting rods 11 to move outward from the grooves 13, thereby pushing the two ends of the brush 12 to press tightly against the inner wall of the cylinder 1. After the carbon aerogel raw material is distilled, the reduction motor 7 can be started to drive the brush 12 to rotate, which can effectively brush off the residue adhering to the inner wall of the cylinder 1.

[0033] Referring to Figure 2, vibration motors 20 are fixedly installed on both sides of the bottom of the cylinder 1. By starting the vibration motors 20, the falling of residue inside the cylinder 1 can be accelerated and blockage can be prevented.

[0034] Referring to Figure 4, the top end of the steam pipe 18 passes through the inner wall of the material tank 15 and is fixedly connected to the top end of the spiral tube 17. The bottom end of the spiral tube 17 is fixedly connected to the output pipe 19, and the output pipe 19 passes through the outer wall of the material tank 15. The steam generated during distillation is input into the spiral tube 17 inside the material tank 15 through the steam pipe 18 to increase the flow area and exchange heat with the carbon aerogel raw material, thereby achieving a preheating effect and utilizing the heat in the steam. Then the steam is sent to the subsequent condensation structure through the output pipe 19.

[0035] Referring to Figure 2, a heat insulation sleeve 2 is fixedly fitted at the bottom of the cylinder 1. An electric heating coil 3 is fixedly connected to the inner wall of the heat insulation sleeve 2. The solvent is heated by the electric heating coil 3. Due to the difference in boiling points, the target component is converted into vapor and separated. The rock wool heat insulation sleeve 2 can prevent heat loss and waste, and avoid burns.

[0036] Referring to Figure 1, a solenoid valve 6 is fixedly connected to the bottom end of the material tank 15, and the bottom end of the solenoid valve 6 is connected to the inside of the cylinder 1. By opening the solenoid valve 6, the solvent waste in the material tank 15 can flow into the cylinder 1 for distillation.

[0037] Referring to Figure 1, a butterfly valve 4 is fixedly connected to the middle of the bottom end of the cylinder 1. Three support legs 5 are fixedly connected to the bottom of the cylinder 1. The support legs 5 can raise the height of the cylinder 1, providing space for the installation of the butterfly valve 4. By opening the butterfly valve 4, the residue inside the cylinder 1 can be discharged for easy cleaning.

[0038] Referring to Figure 2, the brush 12 is attached to the inner wall of the cylinder 1, so that when the brush 12 rotates around the vertical axis 8, it can effectively brush off the distillation residue adhering to the inner wall of the cylinder 1.

[0039] Referring to Figure 4, the top of the material tank 15 is fixedly connected to the inlet 16, and the solvent waste generated during the preparation of carbon aerogel can be fed into the material tank 15 through the inlet 16.

[0040] Working principle: Solvent waste from the carbon aerogel preparation process is fed into material tank 15. By opening solenoid valve 6, it flows into cylinder 1. The solvent is heated by heating coil 3. Due to the difference in boiling points, the target component is converted into vapor and separated. After condensation, it is converted back into liquid, thus achieving recovery. The vapor generated during distillation in this recovery device is fed into spiral tube 17 inside material tank 15 via steam pipe 18 to increase the flow area and exchange heat with the carbon aerogel raw material, achieving preheating and utilizing the heat in the vapor, which is more energy-efficient. Simultaneously, during distillation... During the process, the geared motor 7 is started, driving the stirring blades 9 on the vertical shaft 8 to agitate the solvent, thereby rapidly heating it to improve the distillation efficiency. The two ends of the brush 12 in the cleaning assembly can be tightly pressed against the inner wall of the cylinder 1 under the action of the spring sheet 14. After the carbon aerogel raw material is distilled, the geared motor 7 can be started to drive the brush 12 to rotate, which can effectively brush off the residue adhering to the inner wall of the cylinder 1. After opening the butterfly valve 4, the vibration motor 20 can be started to accelerate the falling of the residue and prevent blockage, so as to achieve rapid cleaning of the inner wall of the recovery device and convenient maintenance. The rod of the brush 12 has a certain elasticity and can achieve small deformation.
