This often necessitates multiple re-grinding processes, leading to low grinding efficiency. Furthermore, the filter plates used for screening after grinding are prone to clogging. Therefore, a graphene processing technology needs to be designed to solve these problems. Summary of the Invention

Detailed Implementation

[0035] A graphene processing technology, comprising the following steps:

[0036] Step 1: Crush the raw materials;

[0037] Step 2: Place the crushed raw materials into the screening device;

[0038] Step 3: Screen the raw materials;

[0039] Step 4: Making graphene.

[0040] The raw material used in step one is graphite.

[0041] See Figure 1-13 A schematic diagram of an embodiment of the present invention, in which four gears II 106 are driven to rotate by a motor 102, is shown. Further,

[0042] The screening device includes a top cover 101, a motor 102 fixedly connected to the top cover 101, and a gear I 103 fixedly connected below the motor 102; the output shaft of the motor 102 passes through the gear I 103, and a gear box I 104 is fixedly connected below the output shaft of the motor 102; four gears II 106 are rotatably connected inside the gear box I 104, and each gear II 106 is meshed with gear I 103; a box cover I 105 is fixedly connected to the gear box I 104.

[0043] The top cover 101 can support the motor 102; the motor 102 drives the gear box I 104 to rotate through the output shaft, and the rotation of the gear box I 104 can drive the four gears II 106 to rotate. The four gears II 106 mesh with the gear I 103, so that when the four gears II 106 and the gear I 103 rotate relative to each other, the gears II 106 themselves rotate; the cover I 105 can protect the four gears II 106 and the gear I 103.

[0044] See Figure 1-13 This shows a schematic diagram of an embodiment of the present invention in which the rotary drum 204 is driven to perform linear reciprocating motion by the turntable I107. Further,

[0045] Each gear II 106 is fixedly connected to a rotating shaft I, each rotating shaft I passing through a cover I 105. Each rotating shaft I is fixedly connected to a turntable I 107, each turntable I 107 is rotatably connected to a connecting rod 108, each connecting rod 108 is rotatably connected to a rotating shaft II, each rotating shaft II is fixedly connected to a slider 203, each rotating shaft II passes through a corresponding slider 203, and each rotating shaft II is rotatably connected to a rotating cylinder 204. Four cover II 201s and four gear boxes II 202s are fixedly connected to the outside of the gear box I 104, and each rotating cylinder 204 is slidably connected between a corresponding cover II 201 and a gear box II 202.

[0046] The rotating shaft I enables the corresponding turntable I 107 and gear II 106 to rotate synchronously; the rotation of turntable I 107 drives the connecting rod 108, which in turn pulls the rotating shaft II and the slider 203 to move; the cover II 201 and the gear box II 202 can restrict the rotating cylinder 204, the rotating shaft II and the slider 203 to only perform linear reciprocating motion within a limited range.

[0047] See Figure 1-13 A schematic diagram of an embodiment of the present invention in which the gear III 205 is driven to rotate by the rack 206 is shown. Further,

[0048] Each rotating drum 204 has a gear Ⅲ 205 fixedly connected to its outer side, and each gear box Ⅱ 202 has a rack 206 fixedly connected to its inner side. Each gear Ⅲ 205 is meshed with the corresponding rack 206.

[0049] When the rotating drum 204 moves back and forth in the inward and outward directions, it can drive the corresponding gear III 205 to move back and forth, and thus move relative to the rack 206. At this time, the gear III 205 rotates under the action of the rack 206; the rotation of the gear III 205 can drive the corresponding rotating drum 204 to rotate around the axis of the rotating drum 204 at the same time.

[0050] See Figure 1-13 The diagram shows an embodiment of the present invention in which multiple stirring rods I302 are driven to rotate by a turntable II301. Further,

[0051] Each of the said rotating shafts I passes downward through the gear box I104, and a turntable II301 is fixedly connected below each of the said rotating shafts I. Multiple stirring rods I302 are fixedly connected to each turntable II301.

[0052] The rotation of gear II 106 can drive the rotation of shaft I, which in turn drives the corresponding turntable II 301 to rotate; the rotation of gear II 106 can drive the corresponding stirring rod I 302 to rotate; the rotation of stirring rod I 302 can stir the graphene raw material near the inner side.

[0053] See Figure 1-13 A schematic diagram of an embodiment of the present invention, in which the stirring rod II 403 is driven to rotate by the turntable III 401, is shown. Further,

[0054] Each rotating drum 204 has a rotating disk Ⅲ401 fixedly attached below it, and four stirring rods Ⅱ403 are fixedly attached to each rotating disk Ⅲ401.

[0055] Each rotating drum 204 simultaneously revolves, rotates, and reciprocates linearly, thereby driving the corresponding stirring rod II 403 to perform the above three movements. The rotation of the stirring rod II 403 can stir the raw materials on the outside, and at the same time, the rotation and reciprocating motion can agitate the raw materials inside, which can further improve the stirring efficiency.

[0056] See Figure 1-13 This shows a schematic diagram of an embodiment of the present invention in which the interior of the stirring tank 204 is agitated by the agitator 405. Further,

[0057] Each of the rotating shafts II passes downward through the rotating cylinder 204 and the turntable III 401. A screw 402 is fixedly connected to the lower part of each rotating shaft II. A fixing plate 404 is fixedly connected to the lower part of each screw 402 and the corresponding four stirring rods II 403. A turning plate 405 is slidably connected to each of the four stirring rods II 403. The turning plate 405 is threadedly connected to the corresponding screw 402.

[0058] The screw 402 is fixed to the rotating shaft II, thus maintaining a relatively fixed state. When the turntable III 401 rotates, it can rotate relative to the screw 402, which in turn causes the tumbling plate 405 to rotate relative to the screw 402, thus enabling the tumbling plate 405 to move along the direction of the screw 402. Since the tumbling plate 405 follows the turntable III 401 and the rotating drum 204 to perform reciprocating motion and clockwise and counterclockwise alternating rotation, the tumbling plate 405 can perform reciprocating motion in the up and down direction, thereby turning over the inside of the mixing drum 109, thereby improving the mixing efficiency.

[0059] See Figure 1-13 The diagram shows an embodiment of screening via sieve plate 502 according to the present invention. Further,

[0060] A mixing drum 109 is fixedly connected below the top cover 101, and a sieve plate 502 is slidably connected inside the mixing drum 109; a storage cylinder 509 is fixedly connected below the mixing drum 109, and a discharge port 510 is fixedly connected below the storage cylinder 509; four support columns 511 are fixedly connected below the storage cylinder 509, and a base plate 512 is fixedly connected below the support columns 511.

[0061] The sieve plate 502 can screen the agitated raw materials, allowing the screened raw materials to enter the storage cylinder 509 below, and the raw materials can be taken out through the discharge port 510; the four support columns 511 and the base plate 512 can support the entire device.

[0062] See Figure 1-13 A schematic diagram of an embodiment of the present invention in which the sieve plate 502 is vibrated by protruding cylinder I 503 and protruding cylinder II 504 is shown. Further,

[0063] A rotating rod 501 is fixedly connected below gear I 103. The rotating rod 501 passes through the screen plate 502. A protruding cylinder II 504 is fixedly connected below the rotating rod 501. A protruding cylinder I 503 is fixedly connected below the screen plate 502. A sliding cylinder 506 is slidably connected to the outside of protruding cylinder I 503 and protruding cylinder II 504. The sliding cylinder 506 is fixedly connected to the bottom of the screen plate 502. An outer cylinder 508 is slidably connected to the outside of the sliding cylinder 506. The outer cylinder 508 is fixedly connected to the bottom of the storage cylinder 509. A spring 507 is fixedly connected between the bottom of the sliding cylinder 506 and the storage cylinder 509.

[0064] The rotating rod 501 can drive the convex cylinder II 504 to rotate, thereby causing the convex cylinder I 503 and the convex cylinder II 504 to rotate relative to each other; the spring 507 can pull the convex cylinder I 503 to keep the convex cylinder I 503 and the convex cylinder II 504 close together. At this time, the relative rotation of the convex cylinder I 503 and the convex cylinder II 504 can drive the convex cylinder I 503 to shake up and down, thereby driving the screen plate 502 to shake. The shaking of the screen plate 502 prevents the blockage caused by the raw materials.
