▎ 摘　　要

NOVELTY - Graphene/cement dispersing device comprises a pneumatic conveying station (1), a reducing joint (2), a first pneumatic quick-inserting air pipe joint (3), an air pipe, a second pneumatic quick-inserting air pipe joint, a first hose (6), an elliptical mixing device (7), a second hose and a pagoda-shaped joint. The outlet of the pneumatic conveying station is connected to the large-diameter end of the reducing joint. The small-diameter end of the reducing joint, the first pneumatic quick-inserting air pipe joint, the air pipe, the second pneumatic quick-inserting air pipe joint and first hose are sequentially connected. The first hose is connected to the inlet end of the elliptical mixing device. The second hose is connected to the outlet end of the elliptical mixing device. The second hose and inlet of the pneumatic conveying station are connected through the pagoda-shaped joint. The two ends of the elliptical mixing device have a small diameter and a large middle diameter. USE - The device is useful for preparing graphene modified cement base material and in the construction engineering (claimed). ADVANTAGE - The device utilizes high-speed airflow, which ensures countless collision and friction of graphene and cement particles in a limited space and thus achieves uniform dispersion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene modified cement base material, comprising dispersing graphene and cement in the dispersing device to obtain graphene-cement mixture, and mixing the graphene-cement mixture with water and stirring to form a graphene-modified cement substrate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene/cement dispersing device.
