Description

Technical Field

[0001] This invention relates to the field of metal material preparation technology, specifically to a preparation apparatus and method for graphene-coated metal materials. Background Technology

[0002] The preparation device for graphene-coated metal materials involves introducing airflow into the bottom of a tank to suspend and tumble the metal powder, and then introducing a small amount of carbon source gas to ensure that all metal powder particles come into contact with the carbon source gas, thereby forming a complete and uniform graphene coating layer on the surface of the metal powder particles.

[0003] Patent CN219464762U discloses a metal powder preparation apparatus, comprising: a melting chamber having a liquid outlet for preparing molten metal liquid; an atomizing chamber having a liquid inlet connected to the liquid outlet; a first ultrasonic component disposed in the atomizing chamber and located below the liquid inlet to provide a first vibration wave to the molten metal liquid to obtain primary droplets; and a second ultrasonic component disposed in the atomizing chamber and located below the first ultrasonic component to provide a second vibration wave to the primary droplets to obtain secondary droplets; wherein the particle size of the secondary droplets is smaller than that of the primary droplets. This patent effectively solves the technical problem that traditional metal powder preparation apparatuses are unable to prepare fine powder with a diameter of less than 50 μm due to the limitation of the vibration frequency of ultrasonic equipment.

[0004] However, current metal powder preparation devices have the following problems: uneven contact between the carbon source gas and the metal powder during the preparation of graphene-coated metal materials leads to substandard quality of the graphene-coated metal materials. Furthermore, the graphene-coated metal powder easily clogs the pores of the perforated tube, resulting in poor carbon source gas ejection. Additionally, the graphene-coated metal powder is prone to agglomeration, leading to poor output. Therefore, we propose a preparation device and method for graphene-coated metal materials.

When using this device, the operator connects the input pipe to the connector of the powder pipe 2 and the carbon source pipe to the connector of the graphene powder blowing pipe 12. The carbon source gas is input into the carbon source pipe and enters the graphene powder blowing pipe 12. The carbon source gas is then input into the perforated pipe 10 and blown out from the round hole of the perforated pipe 10. The operator turns on the electric powder spraying head 3 and simultaneously starts the heating ring 6. The heating ring 6 begins to heat up, and the metal powder sprayed from the electric powder spraying head 3 is heated by the heating ring 6.

The heating ring 6 heats the metal powder, and the carbon source gas comes into contact with the heated metal powder. The second motor 8 on the bracket 7 is then activated. The rotating shaft drives the disc rod 9 to rotate forward. The disc rod 9 rotates forward in the tank 1. The disc rod 9 drives the perforated tube 10 to rotate forward. The perforated tube 10 drives the perforated fan 11 to rotate forward. During the rotation of the perforated fan 11, the perforated fan 11 fans the metal powder sprayed from the electric powder spraying head 3 to suspend it, so that the carbon source gas can fully and evenly contact the surface of the metal powder. When the surface of the metal powder is coated, it falls downward. The rotating shaft of the motor 502 drives the sweeping disc 503 to rotate forward. The sweeping disc 503 sweeps the graphene-coated metal powder below the tank 1 into the discharge pipe 4. The discharge pipe 4 discharges the graphene-coated metal powder.

At the same time, the graphene powder blowing tube 12 supports the square frame 136. As the protruding post 135 rotates, the surface of the protruding post 135 contacts the protruding ring 139. Under the action of the extrusion force, the protruding ring 139 drives the sliding rod disk 137 to move to the right. The sliding rod disk 137 slides to the right in the square frame 136. The spring 138 on the sliding rod disk 137 begins to extend.
