Description

Technical Field

[0001] The invention relates to the technical field of graphene coating processing, in particular to a graphene powder coating filtering device. Background Art

[0002] Graphene is an allotrope of carbon. Carbon atoms are bonded in sp² hybridization to form a single-layer hexagonal honeycomb lattice graphene. Graphene has excellent optical, electrical and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine and drug delivery. During transportation or storage, graphene powder often gets damp and agglomerated due to improper storage. Therefore, before it is put into use, the graphene powder needs to be screened so that the graphene powder meets the use requirements. The production process of graphene coatings is generally to add graphene powder to solvent-based coatings, and after uniform dispersion, a functional coating with anti-corrosion, conductive and other functions is obtained.

[0003] The existing device mainly screens the graphene powder through a filter screen. The existing technology is similar to a graphene material screening device. The structure of patent number CN118045759B includes a screening tank, and a feed hopper, a discharge pipe and a slag discharge pipe are respectively arranged at the upper end, the side wall and the lower end of the screening tank, and also includes: a screening shell rotatably connected in the screening tank, the upper and lower ends of the screening shell are both conical, and the lower end of the screening shell is evenly annularly provided with multiple screening nets. The conveying component conveys the material in the conveying pipe upward, and the large-particle agglomerated graphene material in the conveying pipe can be heated and dried by electric heating until the large-particle agglomerated graphene material moves to the feeding port. The secondary crushing component refines the material at the feeding port by conveying the material upward by the conveying component, and then crushes and refines the large-particle agglomerated graphene material flowing out of the feeding port, and the crushed graphene material falls into the screening shell from the arc-shaped material port along the upper end of the screening shell for further screening, but the device still has places that can be optimized.

[0004] The existing devices mainly use a flat screen to filter and screen the graphene powder, which makes it difficult for some devices to perform rotational screening on the graphene powder, resulting in some large-particle graphene powder easily accumulating on one side of the screen. Secondly, some devices mainly limit the cylindrical screen to be placed inside the body, which makes it difficult for some devices to drive the rotating cylindrical screen to vibrate synchronously, resulting in some devices being difficult to vibrate and screen the graphene powder. Finally, a large amount of agglomerates are easily present in some stored graphene raw materials, making it difficult for some devices to grind the agglomerated graphene powder, resulting in some devices easily discharging a large amount of large-particle graphene materials, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a graphene powder coating filtering device is proposed. Summary of the invention
