When the movable seat 14 moves up to the initial position, as the servo motor 52 drives the fourth rotating shaft 51 and the fixed box 54 to rotate again, the second guide block 67 located in the third guide groove 69 slides into the second guide groove 66. When the staff needs to collect the graphene in the collection box 10, the staff drives the collection box 10 to move upward to disengage the positioning sleeve 20 from the positioning block 73, and the collection box 10 can be removed, which is convenient for collecting the graphene in the collection box 10.

[0042] A method for preparing graphene by electric field stripping of intercalated graphite in this embodiment uses the above-mentioned device for preparing graphene by electric field stripping of intercalated graphite, comprising the following steps:

[0043] Step 1: injecting the graphene-containing solution into the water inlet shell 4 through the water inlet pipe 7, filtering the solution through the filter screen 3 located below the water inlet shell 4, and the filtered solution enters the first liquid collecting tank 8;

[0044] Step 2: The filtered solution is discharged through the drain pipe 11 on the first liquid collecting tank 8, and the filtered material remains on the filter screen 3;

[0045] Step 3: When the filtered material needs to be dried, the support ring 2 and the filter screen 3 located below the water inlet shell 4 are moved to the bottom of the drying shell 5 through the position adjustment component, the solution dripping from the filter screen 3 is collected by the second collecting tank 9, and the filtered material located below the drying shell 5 is dried by the stirring and drying structure;

[0046] Step 4: After drying, graphene is obtained, and the support ring 2, the filter screen 3 and the graphene located below the drying shell 5 are moved to the collection station through the position adjustment component, and the staff collects the graphene.

[0047] Working principle: During operation, a solution containing graphene is injected into the water inlet shell 4 through the water inlet pipe 7. The design of the water inlet shell 4 prevents the solution from splashing out of the support ring 2. The solution is filtered through the filter screen 3 located below the water inlet shell 4. The filtered solution enters the first liquid collecting tank 8. The filtered solution is discharged through the drain pipe 11 on the first liquid collecting tank 8. The filtered material stays on the filter screen 3. When the filtered material needs to be dried, the support ring 2 and the filter screen 3 located below the water inlet shell 4 are moved to the bottom of the drying shell 5 through the position adjustment component, and the second filter screen 3 is used to adjust the position of the filter screen 3. The liquid collecting box 9 collects the solution dripping from the filter screen 3, and the next unused support ring 2 and filter screen 3 are moved to the bottom of the water inlet shell 4, and the filter material under the drying shell 5 is dried by the stirring and drying structure. After the drying is completed, graphene is obtained, and the support ring 2, filter screen 3 and graphene under the drying shell 5 are moved to the collection station by the position adjustment component. The staff collects the graphene, and the staff does not need to transfer the filter material to the drying equipment, and can directly complete the filtering and drying of the graphene solution, thereby improving the production efficiency and facilitating practical use.

[0048] When the filtered material is located below the drying shell 5, the movable seat 14 is driven downward by the hydraulic telescopic rod 15, and the movable seat 14 drives the movable disk 13 to move downward through the first tooth plate 17 and the elastic member, and the movable disk 13 drives the first gear ring 36 and the first guide column 37 to move downward synchronously through the first support portion 39 and the first slider 40, and the movable disk 13 drives the second gear ring 41 and the second guide column 42 to move downward synchronously through the second support portion 44 and the second slider 45. When the movable disk 13 contacts the top of the support ring 2, the hydraulic telescopic rod 15 drives the movable seat 14 to continue to move downward, the movable disk 13 stops moving downward, and the first support portion 39 and the first slider 40 drive the first gear ring 36 and the first guide column 37 to move downward synchronously. A toothed plate 17 drives the fixed plate 46 to move downward relative to the movable disk 13, the compression spring 48 is in a compressed state, and the first toothed plate 17 moves vertically relative to the fixed disk 12, the first toothed plate 17 drives the first gear 25 and the second rotating shaft 24 to rotate, the second rotating shaft 24 drives the first bevel gear 23 and the support sleeve 19 to rotate through the second bevel gear 26, the support sleeve 19 drives the first rotating shaft 18 and the movable disk 13 to rotate relative to the fixed disk 12 and the support ring 2 through the first guide block 21, the movable disk 13 drives the third rotating shaft 30 and the rotating sleeve 33 to revolve around the first rotating shaft 18, and the second gear 34 is on the first gear ring The third gear 35 rolls on the second gear ring 41, so that the rotating sleeve 33 drives the rotating box 27 to rotate, and changes the position of the stirring blade 29 in the support ring 2. At the same time, the third rotating shaft 30 and the third bevel gear 31 rotate, and the third bevel gear 31 drives the first connecting shaft 28 and the stirring blade 29 to rotate through the fourth bevel gear 32. The stirring blade 29 stirs the filter in the support ring 2, and the heating plate 16 heats and dries the filter in the support ring 2. When the first tooth plate 17 descends to the preset position, the hydraulic telescopic rod 15 drives the movable seat 14 and the first tooth plate 17 to move up, and the movable disk 13 The height remains unchanged, the fixed plate 46 moves up relative to the movable disk 13, and the length of the compression spring 48 increases. When the first tooth plate 17 moves up to the preset height, and the movable disk 13 is still in contact with the support ring 2 at this time, the hydraulic telescopic rod 15 drives the movable seat 14 and the first tooth plate 17 to move down again, and by driving the first tooth plate 17 to move back and forth in the vertical direction, the stirring blade 29 can stir the filter in the support ring 2, change the position of the filter, and speed up the drying efficiency. When the drying is completed, the movable seat 14 is driven to move up to the initial height by the hydraulic telescopic rod 15, so that the stirring blade 29 is no longer located in the support ring 2;

[0049] The fourth rotating shaft 51 and the tray 50 are driven to rotate by the servo motor 52, and the tray 50 drives the support ring 2 and the filter screen 3 to rotate through the fixed box 54, and the second guide block 67 located above the fixed box 54 slides in the second guide groove 66 on the arc plate 65. When the support ring 2 and the filter screen 3 move to the collection station, the corresponding support ring 2 and the filter screen 3 are located above the collection box 10, and the corresponding second guide block 67 slides into the third guide groove 69 on the connecting block 68. When the hydraulic telescopic rod 15 drives the movable seat 14 to move downward, the movable seat 14 drives the connecting block 68 to move downward synchronously, and the connecting block 68 passes through the second guide groove 66. The block 67 drives the second tooth plate 60 to move downward, and the connecting block 68 enters the fixed box 54 through the avoidance hole 71, and the second tooth plate 60 drives the fixed block 61 to slide relative to the third guide column 62. The design of the fixed block 61 and the third guide column 62 allows the second tooth plate 60 to move smoothly in the vertical direction. At the same time, the second tooth plate 60 drives the fourth gear 59, the third connecting shaft 58 and the second damping plate 57 to rotate. The second damping plate 57 drives the first damping plate 56, the second connecting shaft 55 and the support ring 2 to flip through the friction force. When the support ring 2 flips 180 degrees, the graphene on the filter screen 3 falls into the collection box 1. 0, and the support block 63 on the first damping disc 56 contacts with a corresponding stop block 64. As the second tooth plate 60 continues to move downward, the second damping disc 57 cannot drive the first damping disc 56 to rotate synchronously by friction. The impact force generated by the collision between the support block 63 and the stop block 64 shakes the graphene adhered to the filter screen 3 into the collection box 10. When the hydraulic telescopic rod 15 drives the movable seat 14 to move upward, the second tooth plate 60 drives the fourth gear 59 to rotate in the opposite direction to make the support ring 2 flip in the opposite direction. When the support ring 2 flips in the opposite direction by 180 degrees, the support block 63 contacts with another ... The second tooth plate 60 continues to move upward, and the first damping disk 56 and the support ring 2 remain stationary, ensuring that the support ring 2 automatically stops after flipping to one hundred and eighty degrees. When the movable seat 14 moves up to the initial position, as the servo motor 52 drives the fourth rotating shaft 51 and the fixed box 54 to rotate again, the second guide block 67 located in the third guide groove 69 slides into the second guide groove 66. When the staff needs to collect the graphene in the collection box 10, the staff drives the collection box 10 to move upward to disengage the positioning sleeve 20 from the positioning block 73, and the collection box 10 can be removed, which is convenient for collecting the graphene in the collection box 10.
