NOVELTY - The suspension has a mixing chamber fixed on a left end of a high shear mixer (1). An inner end of the mixing chamber is provided with a screw thread. A lower screw thread of a rotating shaft (3) is fixed with a bottom plate (4). The bottom plate is fixedly installed on a lower screw threaded of the rotating shaft. An anti-overflow component comprises an annular track (28) embedded in the mixing cavity. A linkage ring (29) is wrapped on an outer end of an screw thread shaft. A movable fan-shaped plate is rotating in a mixing cavity (2). USE - High-shear preparation device for graphene of a suspension liquid. Uses include but are not limited to water wing propeller, ocean style mixing propeller and axial flow turbine. ADVANTAGE - The device reduces dispersing blade in the process of rotating, can ensure the high cutting of the suspension graphene more efficient, and ensures to avoid the energy consumption problem caused by the positive and negative screw thread of the rotating rod, and reduces the vortex after the dispersion blade is moved upwards. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a high-shear preparation device for graphene. 3Screw thread rotating shaft 4Bottom plate 6Inner locating rod 8Inner through hole 9Sliding ring 11Central shaft 16Bevel gear 17Linkage bevel gear rod 21Dispersing blade 22Inner sliding cylinder 23Locating sliding rod
