Problems solved by technology

But it has the following disadvantages: it can only perform one transverse shear and one longitudinal shear on the graphite sheet at one time, and cannot change the shearing precision of the shearing mechanism along with the shearing process of the graphite sheet, and the shearing efficiency is low , the graphite material whose precision is not up to the standard cannot be sent back to the shearing working chamber for re-shearing in time, and it cannot be guaranteed that the output is the material with the precision up to the standard

Embodiment 1

[0034] Such as figure 1 A graphene multi-stage peeling device shown includes a fixed housing 14 supported on the ground by support legs 1, a fixed ring that is located in the middle of the inner side of the fixed housing 14 and is fixedly connected to the fixed housing 14 through the connecting plate 15 body 9, and the rotating sphere 7 embedded in the inner ring side of the fixed ring body 9, the inside of the rotating sphere 7 is provided with two shearing chambers 40 symmetrically distributed about its vertical center line, and the shearing chambers The longitudinal section of the profile of 40 is shuttle-shaped, and the shearing chamber 40 is provided with a fixed sphere 22 in the middle, surrounded by the second grinding body 30 outside the middle of the fixed sphere 22, and positioned on the upper and lower sides of the fixed sphere 22. The first grinding body 27, the first grinding body 27 adaptive cover is set on the corresponding side of the fixed ball 22, and the sid...

Embodiment 2

[0042] The difference between this embodiment and embodiment 1 is:

[0043] In this example, if image 3 As shown, the side wall of the shearing chamber 40 is fixed with a transverse fixed ring gear 24 corresponding to the area where the first grinding body 27 is located, and the circumferential side of the first grinding body 27 is fixed with a fixed ring gear that is interlocked with the transverse fixed ring gear 24. Combined transversely rotating ring gear 28; as Image 6 As shown, the inner surface of the second grinding body 30 is fixed with a longitudinally rotating ring gear 32 , and the outer surface of the fixed ball 22 is uniformly spread with longitudinally fixed ring gears 33 matching the longitudinally rotating ring gear 32 . The horizontally rotating ring gear 28 can rotate with the rotation of the first grinding body 27, while the horizontally fixed ring gear 24 is relatively fixed in the lateral direction. Strengthen the transverse shear ability to the graph...

Embodiment 3

[0046] The difference between this embodiment and embodiment 1 is:

[0047] In this example, if figure 1 and figure 2 As shown, the interior of the fixed sphere 22 is hollow to form a cooling cavity 29, and the fixed sphere 22 and the corresponding connecting rod are pierced with a coolant input pipe 12 that communicates with the cooling cavity 29 and penetrates to the outside of the fixed housing 14. . Fill the cooling cavity 29 with cooling water or liquid nitrogen through the cooling liquid input pipe 12 in advance, so that the graphite material and grinding parts can absorb heat and cool down during the working process of the device, so as to prevent the graphite material from being bonded by heat and ensure the graphite peeling effect , and is conducive to the protection of abrasive parts.

[0048] Others are with embodiment 1.

Abstract

The invention discloses a graphene multistage stripping device, which belongs to the technical field of graphene production, and comprises a rotating ball body driven by a motor and a fixed ring bodyarranged on the outer side of the rotating ball body, wherein the rotating ball body is internally provided with the fixed ball body, a second grinding body and a first grinding body, the first grinding body ring is used for transverse shearing, and the second grinding body is used for longitudinal shearing; a feeding through opening and a discharging through opening are formed in the top and thebottom of the fixed ring body respectively, a feeding opening and a discharging opening are formed in the two opposite sides of the rotating ball body respectively, and a filter screen is installed atthe upper end opening of the discharging through opening. The first grinding body is in linkage with the rotating ball body through an outer sleeve, a fixed conical gear ring and a walking conical gear, and lifting type movement is achieved through a rotating shaft, a fixed carrier ring, an electromagnet, a connecting circular plate and a permanent magnet. The shearing precision of the shearing mechanism can be changed along with the shearing process, and graphite materials with the precision not reaching the standard can be sent back into the shearing working cavity in time to be sheared again.

Description

technical field [0001] The invention relates to the technical field of graphene production, in particular to a graphene multistage stripping device. Background technique [0002] Graphene is the thinnest and hardest nanomaterial known in the world. It has good electrical, optical and thermal properties, as well as excellent mechanical strength and flexibility. It can be used in composite materials, coatings, supercapacitors and other fields. Graphene The production of graphene usually requires the use of graphene exfoliation equipment. [0003] At present, a graphene dry-state stripping device is disclosed in the patent with the authorized notification number CN 108855479 B, which uses an air pump to introduce the airflow mixed with graphite dry powder raw materials into the gap, and disperses graphene by airflow instead of traditional solvents. The graphite sheet is first sheared horizontally and then longitudinally sheared, so that the probability of the graphite dry powd...
