[0002] Graphene powder is widely used in composite materials, energy devices, and other fields due to its excellent mechanical, electrical, and thermal properties. However, graphene powder particles are small and have high surface energy, making them prone to agglomeration and forming large aggregates.

Traditional mixing equipment lacks an effective sealing structure, and powder is prone to spilling out from the equipment gaps during the mixing process, resulting in excessively high dust concentration in the processing workshop, which not only pollutes the environment but also endangers the health of operators.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Example

[0023] like Figures 1-4As shown, this embodiment proposes a graphene powder pre-dispersion device, including a transport component 1. The transport component 1 includes a device base 101, with several casters 102 fixedly connected to the bottom of the device base 101. A push rod 103 is fixedly connected to the rear end of the device base 101. A stirring component 2 is provided at the top of the rear end of the device base 101. A stirring tank component 3 is also provided on the device base 101. The stirring component 2 disperses and stirs the graphene powder in the stirring tank component 3. The stirring component 2 includes a lifting slide. A servo motor 205 is fixedly connected to a lifting slide 204. The output end of the servo motor 205 passes through the lifting slide 204 and is fixedly connected to a pressing plate 206. Several stirring rollers 207 are fixedly connected to the side of the pressing plate 206 away from the servo motor 205. The stirring rollers 207 are evenly distributed circumferentially along the axis of the pressing plate 206. The stirring tank assembly 3 includes a storage tank 301, which is fixedly connected to the equipment base 101. A rotating groove 30 is formed on the upper inner wall of the storage tank 301. 4. A turntable 305 is rotatably installed inside the rotating groove 304. The turntable 305 rotates with the pressing plate 206. Several through holes are opened on the turntable 305, and the stirring rod 207 is located in the through holes. By using the servo motor 205 to drive the pressing plate 206 to rotate, the stirring rod 207 stirs and disperses the powder inside the storage tank 301. By setting the turntable 305, the powder can be prevented from overflowing from the storage tank 301 during the dispersion process, reducing dust generation in the processing workshop. At the same time, by pushing the transport component 1, This facilitates the transfer of the mixed graphene powder to the next processing position. The mixing tank assembly 3 also includes a cleaning component 307, of which several are fixedly connected to the through holes of the turntable 305 and to the side of the cleaning component 307 closest to the inner wall of the storage tank 301. The cleaning component 307 is a conical empty tank made of elastic material, with a through groove on its side wall, which allows the conical empty tank to be elastically expanded. When the stirring rod 207 is inserted from the large end of the cleaning component 307, the side wall of the empty tank is radially compressed by the steel pipe, and the groove expands outward, causing the entire empty tank to open. This allows the inner side wall of the cleaning component 307 to fit tightly against the surface of the stirring rod 207, reducing the possibility of powder leakage. When the stirring rod 207 moves, the inner side wall can clean the graphene powder on the surface of the stirring rod 207 through contact friction.

[0024] like Figure 2As shown, the stirring assembly 2 also includes a slide rail 201, which is fixedly connected to the top of the equipment base 101. A screw 202 is rotatably installed inside the slide rail 201. A stepper motor 203 is fixedly connected to one end of the slide rail 201, and the output end of the stepper motor 203 is fixedly connected to the screw 202. A lifting slide 204 is slidably connected to the slide rail 201 and is connected to the screw 202 via a threaded connection. By using the stepper motor 203 to drive the screw 202 to rotate, the lifting slide 204 is raised. During the raising of the lifting slide 204, the stirring roller 207 is also raised. During the raising of the stirring roller 207, the cleaning component 307 cleans the powder on the surface of the stirring roller 207.

[0025] like Figure 2 As shown, the stirring assembly 2 also includes a scraper 208, which is disposed on the side of the stirring roller 207 on the outer ring of the pressing plate 206, and the scraper 208 is located on the side where the stirring roller 207 contacts the inner wall of the storage tank 301, with the scraper 208 closely attached to the inner wall of the storage tank 301. By using the scraper 208, graphene powder on the inner wall of the storage tank 301 can be scraped off, reducing residue on the inner wall.

[0026] like Figure 3 As shown, the mixing tank assembly 3 also includes a discharge valve 306, which is fixedly connected to the bottom of the storage tank 301. A feed inlet 302 is provided on one side of the upper end of the storage tank 301. Powder is fed into the interior of the storage tank 301 through the feed inlet 302, and the powder is poured out by controlling the opening and closing of the discharge valve 306. An annular support plate 303 is fixedly connected to the side wall of the storage tank 301. Threaded holes are symmetrically provided on the support plate 303, and the support plate 303 is fixed to the equipment base 101 by bolts.

[0027] Working principle: First, the push rod 103 pushes the equipment base 101, and the universal wheels 102 at the bottom of the equipment base 101 move the equipment to the designated working position for loading and unloading graphene powder. Then, the storage tank 301 is fixed to the equipment base 101 by the annular support plate 303 on its side wall and bolts. The graphene powder to be dispersed is added into the storage tank 301 through the feed port 302 in the mixing tank assembly 3. Then, the stepper motor 203 is controlled to work, and the stepper motor 203 drives the screw 202 in the slide rail 201 to rotate. Through the threaded transmission between the screw 202 and the lifting slide 204, the lifting slide 204 is driven to move downward along the slide rail 201, so that the stirring roller 207 on the lifting slide 204 passes through the through hole of the turntable 305 and the cleaning part 307 and extends into the storage tank 301. At this time, the cleaning part 307 is radially squeezed by the stirring roller 207, and the inner side wall is tightly attached to the surface of the stirring roller 207. Then, the servo motor 20 is started. 5. The servo motor 205 drives the pressing plate 206 to rotate, which in turn causes the stirring roller 207 to rotate inside the storage tank 301, stirring and dispersing the graphene powder. During the dispersion process, the turntable 305 in the rotating groove 304 on the upper inner wall of the storage tank 301 effectively prevents powder from overflowing. At the same time, the scraper 208 on the side of the stirring roller 207 on the outer ring of the pressing plate 206 contacts the inner wall of the storage tank 301, scraping off the powder adhering to the inner wall and reducing residue. After stirring is completed, Stepper motor 203 rotates in reverse, driving lifting slide 204 to rise via screw 202, simultaneously pulling stirring roller 207 out of storage tank 301. At this time, the inner wall of cleaning component 307 rubs against the surface of stirring roller 207 to clean the powder residue on the surface of stirring roller 207. Finally, the device can be pushed by push rod 103 and caster wheel 102 to open the discharge valve 306 at the bottom of storage tank 301 and pour out the dispersed graphene powder.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
