Description

Technical Field

[0001] The present invention relates to the technical field of graphene, and more particularly to a grinding and stripping device for graphene slurry. Background Art

[0002] Graphene slurry is a liquid mixture formed by dispersing graphene in a liquid medium. It is mainly composed of graphene, dispersant and solvent (such as water, DMF or NMP). Graphene slurry inherits the excellent electrical and thermal properties of graphene and can be used to prepare high-performance conductive materials and heat dissipation materials.

[0003] At present, the graphene slurry on the market is made by adding graphene powder to a solvent, mixing the powder in the solvent, and then sending the mixed solvent into a circulating emulsification pump. The stator and rotor of the circulating emulsification pump shear the mixed solvent, and the shear force is formed by the rotor and the stator. The rotation of the rotor shears the graphene microsheets in the mixed solvent, and particle refinement is achieved through step-by-step enhanced fluid turbulence.

[0004] However, in the process of conveying the graphene mixed slurry to the circulating emulsification pump, there will be a need to adjust the flow rate and stop the conveying. At this time, a valve is needed. However, installing the valve in the middle of the pipeline will cause graphene microflakes to accumulate on the valve closing port when it is closed. The graphene mixed slurry usually has a high viscosity (generally in the range of 500-2000mPa·s). This high viscosity characteristic aggravates the adhesion of the microflakes to the valve sealing surface, which will affect the normal opening and closing of the valve. Summary of the invention

The magnetic coil 513 is energized in the circular ring formed by the first mounting ring 511 and the second mounting ring 512 to generate a magnetic field to control the graphene particles in the graphene mixed slurry. The control slider 55 is slidably installed on the control slide rail 54.

[0057] The feeding flange 41 is used for feeding in a closed manner, the valve body 43 is used for adjusting the flow rate of the graphene mixed slurry and stopping the feeding of the graphene mixed slurry, the valve controller 42 controls the flow or shutoff of the valve body 43, and the feeding mechanism 44 conveys the mixed graphene slurry into the valve body 43. After the graphene mixed slurry passes through the valve body 43 and the feeding flange 41, it is fed into the shearing mechanism 35.

[0058] The feeding mechanism 44 includes a feeding pipe 444 , which is provided with a through hole 443 , on which a closed flange 441 is mounted, and below which a material leveling component 442 is disposed. The material leveling component 442 is disposed in the middle of the feeding pipe 444 .

[0059] The feeding pipe 444 flows through the graphene mixed slurry, the closing flange 441 improves the sealing performance, and the mixing motor 45 provides driving force for the material leveling component 442.

[0060] The material leveling component 442 includes a stirring shaft 4425, one end of which passes through a closed flange 441 and is connected to an output end of a mixing motor 45, the other end of the stirring shaft 4425 is provided with an active bevel gear 4426, a driven bevel gear 4427 is meshed below the active bevel gear 4426, a material leveling shaft 4422 is provided on one side of the driven bevel gear 4427, a closing piece 4424 is sleeved on the outside of the active bevel gear 4426 and the driven bevel gear 4427, the closing piece 4424 is rotatably connected to the stirring shaft 4425 and the material leveling shaft 4422 through a bearing, stirring blades 4423 are equidistantly sleeved on the material leveling shaft 4422, and a connecting block 4421 is installed on the end of the material leveling shaft 4422 away from the driven bevel gear 4427, and the top of the connecting block 4421 is connected to the inner wall of the feeding pipe 444.

[0061] The mixing motor 45 drives the stirring shaft 4425 to rotate, the stirring shaft 4425 synchronously drives the active bevel gear 4426, the active bevel gear 4426 drives the driven bevel gear 4427 to rotate, the driven bevel gear 4427 synchronously drives the material leveling shaft 4422 to rotate, and a closed space is formed between the active bevel gear 4426 and the driven bevel gear 4427 through the closing piece 4424, the stirring blade 4423 rotates to stir the graphene particles in the graphene slurry, and the connecting block 4421 supports the material leveling shaft 4422.

[0062] See also Figures 2 to 11When the graphene mixed slurry is fed into the shearing mechanism 35, the stirring blade 4423 can be rotated to transport it more stably. The moving graphene slurry drives the stirring blade 4423 to rotate and stir during the transportation process to avoid the graphene sticking. When the graphene mixed slurry needs to stop being transported, the valve controller 42 controls the valve body 43 to close, and the mixing motor 45 works at the same time to drive the stirring blade 4423 to rotate to avoid the graphene mixed slurry from forming a sediment due to non-flow. During the stirring process of the graphene mixed slurry, the graphene near the valve part It is difficult to completely cover the mixed slurry, which will cause the graphene to stick to the valve, making it difficult to open and close the valve. At this time, the controller 52 controls the magnetic coil 513 to be energized, and uses the conductive properties of graphene to generate an eddy current effect to keep the particles suspended. The control motor 53 drives the control slider 55 to move toward the position of the stirring blade 4423, so that the graphene particles close to the valve can participate in the stirring process. When the valve body 43 is opened, the mixing motor 45 drives the stirring shaft 4425 to rotate, providing power for the flow of the graphene mixed slurry to avoid difficulty in starting.

[0063] During the stirring process, the slider 55 is controlled to drive the magnetic ring mechanism 51 to move back and forth, and the magnetic ring mechanism 51 drives the graphene particles at different positions to move, thereby achieving the effect of reducing the phenomenon of graphene agglomeration.

[0064] During the initial delivery of the graphene mixed slurry and the re-delivery after the valve is opened, the mixing motor 45 can drive the stirring blade 4423 to rotate, providing driving force for the delivery of the graphene mixed slurry, reducing the power of the emulsification pump motor 31, and improving the transmission efficiency.

[0065] By setting a magnetic coil 513 and passing electricity in the circular ring formed by the first mounting ring 511 and the second mounting ring 512 to generate a magnetic field, the conductive property of graphene is used to generate an eddy current effect, so that the graphene particles near the valve are kept in a suspended state, and the control slider 55 drives the magnetic ring mechanism 51 to move, and drives the graphene particles in the graphene mixed slurry to move to the position of the stirring blade 4423 for stirring, thereby achieving the effect of moving the graphene particles near the valve to the position of the stirring blade 4423 to participate in stirring and prevent accumulation.
