[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a graphene nano material mixer, such as Figure 1-Figure 4 As shown, the mixer includes a mixing barrel 1, a feed pipe 11 and a discharge pipe 12 fixedly installed on the top and bottom of the mixing barrel 1 and connected to the inside of the mixing barrel 1, and a stirring component 2 rotatably arranged in the mixing barrel 1 for material mixing; the stirring component 2 includes a main shaft 21 rotatably connected to the mixing barrel 1, a stirring blade 22 fixedly connected to the main shaft 21, a stirring rod 23 fixedly connected to the bottom of the main shaft 21, and a rotating motor 24 fixedly installed on the top of the mixing barrel 1 for driving the main shaft 21 to rotate.

[0028] In this embodiment, after the material mixed with the graphene nanomaterial is injected into the feed pipe 11 from the feed pipe 11, the main shaft 21 is driven to rotate by the rotating motor 24, so that the stirring blades 22 and the stirring rods 23 arranged on the main shaft 21 can fully stir and mix the materials in the mixing barrel 1, thereby achieving uniform mixing of the graphene nanomaterial, and the mixed graphene nanomaterial can be taken out from the discharge pipe 12.

[0029] Furthermore, in order to control the flow rate of inlet and outlet materials, a solenoid valve 13 is fixedly installed at one end of the feed pipe 11 and the discharge pipe 12 away from the mixing barrel 1; since the solenoid valve 13 can respond and adjust quickly, it can meet the demand for rapid adjustment of flow changes, and thus by starting and stopping the solenoid valve 13, the inflow and outflow speed of the material can be accurately controlled.

[0030] Furthermore, a disturbance component 3 for disturbing the material is rotatably arranged at a position below the feed pipe 11 in the mixing barrel 1; the disturbance component 3 includes a guide plate 31 rotatably arranged at a position below the feed pipe 11 for disturbing the material, a fixed box 32 fixedly installed at the top of the mixing barrel 1, and a driving member 33 arranged in the fixed box 32 for driving the guide plate 31 to rotate; the driving member 33 includes a rotating shaft 331 and a driving shaft 332 rotatably connected in the fixed box 32, and a driving motor 33 fixedly installed at the top of the mixing barrel 1 for driving the driving shaft 332 to rotate. 6 and a transmission member for power transmission arranged between the rotating shaft 331 and the driving shaft 332. The ends of the rotating shaft 331 and the driving shaft 332 away from the fixing box 32 both pass through the fixing box 32 and are fixedly connected to the guide plate 31 and the driving motor 336 respectively; the transmission member includes a transmission wheel A333 and a transmission wheel B335 fixedly mounted on the rotating shaft 331 and the driving shaft 332, and a transmission belt 334 arranged between the transmission wheel A333 and the transmission wheel B335. The transmission wheel A333 and the transmission wheel B335 are connected and transmit power through the transmission belt 334.

[0031] In this embodiment, after the driving shaft 332 is driven to rotate by the driving motor 336, the transmission wheel B335 on the driving shaft 332 will also rotate synchronously. At this time, the transmission wheel B335 can transmit the rotational power of the driving shaft 332 to the rotating shaft 331 installed on the transmission wheel A333 under the transmission action of the transmission belt 334, so that the rotating shaft 331 will drive the guide plate 31 to rotate, and the movement of the guide plate 31 will produce a certain shear force on the material entering the mixing barrel 1 from the feed pipe 11, so that the material is guided from the feed pipe 11 to other parts of the mixing barrel 1, so as to prevent the incoming material from accumulating at the lower position entering from the feed pipe 11, thereby helping to improve the mixing effect and efficiency.

[0032] Furthermore, in order to increase the stability of the equipment, brackets 14 are fixedly installed on all four sides of the outer side of the mixing barrel 1; the installation of the brackets 14 can provide solid support for the mixing barrel 1, thereby reducing the shaking or displacement of the mixing barrel 1 due to vibration during operation or other reasons, ensuring smooth operation of the equipment.

[0033] When in use, firstly, by opening the solenoid valve 13 on the feed pipe 11, the material for preparing the graphene nanomaterial can be quantitatively input from the feed pipe 11 to the mixing barrel 1. When the material is input, the drive motor 336 can drive the drive shaft 332 to rotate, and the drive shaft 332 can transmit the rotational driving force of the drive motor 336 to the rotating shaft 331 under the transmission action of the transmission member, so that the rotating shaft 331 can drive the guide plate 31 to rotate;

[0034] Then, the rotating guide plate 31 will generate a certain shear force on the material entering the mixing barrel 1 from the feed pipe 11, so that the material is guided from the feed pipe 11 to other parts of the mixing barrel 1;

[0035] However, while the guide plate 31 disturbs the material, the rotating motor 24 can be started to drive the main shaft 21 to rotate. At this time, the stirring blade 22 and the stirring rod 23 installed on the main shaft 21 can fully stir and mix the material in the mixing barrel 1 to achieve uniform mixing of the graphene nanomaterials;

[0036] Finally, after mixing, the mixed material can be taken out by opening the solenoid valve 13 on the discharge pipe 12 .

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
