Description

Technical Field

[0001] The present invention relates to the field of graphene alloy material preparation, and in particular to a cleaning and drying device and a preparation method for graphene alloy material preparation. Background Art

[0002] Graphene alloy materials are composites of graphene and metal or alloy matrices to form new materials that combine the excellent properties of graphene with the good processability and ductility of metal matrices. During the preparation process, the materials need to be cleaned and dried. Drying of graphene alloy materials is a key link in the preparation process and directly affects the performance and stability of the materials.

[0003] The patent application with announcement number CN216868982U is a drying device for preparing graphene, specifically a drying device for preparing graphene, which uses hot air to remove moisture when drying graphene. The hot air heat dissipation flow rate inside the box is slow and the drying effect is poor. When collecting, some graphene will adhere to the inner wall of the placement plate, which is very inconvenient to collect. It includes a drying box, a placement plate is slidingly provided in the drying box, and graphene can be placed on the placement plate. Heaters are fixed on both sides of the inner wall of the drying box, and a moving mechanism is provided on the side of the drying box away from the placement plate. The drying fan is fixed on the moving block, and the moving block threaded on the threaded rod can be moved by the motor to drive the threaded rod to rotate, so that the moving block can drive the drying fan to move in the drying box, thereby increasing the output range. The heater in the drying box can heat the air in the drying box, and cooperate with the moving drying fan to increase the air flow rate in the drying box, thereby improving the drying effect.

[0004] During the drying process of the existing drying device, the graphene material is prone to agglomeration, which affects the overall drying effect and the quality of the material in subsequent processing. During the drying process, the graphene material is prone to adhesion to the inside of the drying equipment, resulting in the material being unable to be discharged in time. In addition, some larger particulate impurities may enter the material during transportation. If not cleaned, it is easy to affect the final processing quality.

[0053] A cleaning and drying method for preparing a graphene alloy material includes the cleaning and drying device for preparing a graphene alloy material as described above, and the specific processing steps are as follows:

[0054] S1: The graphene alloy raw material is placed into the drying drum 101 through the feed port 102. At this time, the external hot air is transported into the drying drum 101. At this time, the drying drum 101 is driven to rotate by the motor 202, so that the gear ring 1 401 drives the gear 1 404 to rotate, and the gear 1 404 drives the gear ring 2 408 to rotate, so that the comb shaft 2 409 rotates as a whole, and can rotate on its own under the action of the gear ring 3 411, so as to achieve the effect of stirring and drying the graphene alloy raw material, and the inner wall of the drying drum 101 will rotate along each group of comb shafts 1 403;

[0055] S2: When the drying is completed, the sliding frame 204 can be pushed by the electric push rod 1 205 to move, so that the sleeve 303 slides along the docking tube 306 to expose the sieve hole 307, and then the drying cylinder 101 is tilted on one side by the electric push rod 206. With continuous rotation, the graphene alloy raw material is screened from the sieve hole 307. In the stirring and drying process, the electric push rod 206 can be moved up and down separately to make the comb shaft 1 403 and the comb shaft 2 409 better stir the graphene alloy raw material.

[0056] like Figure 1-7 As shown, after the graphene alloy raw material is placed into the drying drum 101 through the feed port 102, the motor 202 is turned on to rotate the drying drum 101, and the external hot air is transported into the drying drum 101. At this time, the drying drum 101 drives the gear 1 404 to rotate through the gear ring 1 401, so that the comb shaft 1 403 rotates on its own. At the same time, the inner wall of the drying drum 101 rotates around the comb shaft 1 403, so as to avoid the graphene alloy raw material from adhering to the inner wall of the drying drum 101, and the gear 1 404 drives the rotating frame 406 to rotate through the gear ring 2 408, so that the comb shaft 2 409 rotates as a whole, and the gear 2 410 can slide along the gear ring 3 411, so that the comb shaft 2 409 can rotate on its own, so as to avoid the graphene The alloy raw material may agglomerate, and during this process, the electric push rod 206 can push up and down to realize the swing of one side of the drying cylinder 101, thereby improving the stirring effect. Finally, after the drying is completed, the electric push rod 1 205 pushes the sliding frame 204 to drive the sleeve 303 to move, so that the sieve hole 307 is exposed, and the inclination of the drying cylinder 101 cooperates with its rotation to discharge the internal graphene alloy raw material through the sieve hole 307. Through this structure, the graphene alloy raw material can be prevented from sticking to the equipment and agglomerating during the drying process, and the turning drying can improve its drying efficiency, and the swinging during the drying process can further improve the overall effect of stirring drying. Finally, the impurities inside the material can be effectively filtered through the sieve hole 307.

[0057] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
