▎ 摘　　要

NOVELTY - A graphene lubricating oil grading filter device includes a base plate (1), where the base plate is provided with a support mechanism (2), and the support mechanism is provided with a coarse filter mechanism (3) for carrying out first coarse sieve to graphene and a fine filtering mechanism for performing second fine screening for graphene. The coarse filter mechanism is rotatably connected with a coarse filter frame (4) arranged on the base plate. The base plate is further provided with a driving mechanism (5) for driving coarse filter mechanism. The U-shaped frame is provided with a locking mechanism (6) for preventing the coarse filter mechanism from reversing. The fine filtering mechanism is provided with a second cluster discharging port, the bottom of the fine filtering mechanism is provided with a collecting mechanism (8) for automatically collecting the graphene after fine filtering, and the collecting mechanism is controlled by the self-weight change. USE - Graphene lubricating oil grading filter device. DETAILED DESCRIPTION - A graphene lubricating oil grading filter device includes a base plate, where the base plate is provided with a support mechanism, and the support mechanism is provided with a coarse filter mechanism for carrying out first coarse sieve to graphene and a fine filtering mechanism for performing second fine screening for graphene. The support mechanism has a drainage rack for draining rough-filtered graphene to inside of the fine-filtering mechanism. The coarse filter mechanism is rotatably connected with a coarse filter frame arranged on the base plate, the coarse filter frame includes a U-shaped frame, and the U-shaped frame is provided with a feeding port and first agglomerate discharging port, and the lower portion of the first agglomerate discharging port is provided with a first group polymer recycling box. The base plate is further provided with a driving mechanism for driving coarse filter mechanism. The U-shaped frame is provided with a locking mechanism for preventing the coarse filter mechanism from reversing. The fine filtering mechanism is provided with a second cluster discharging port, the lower portion of the second cluster discharging port is provided with a second cluster recycling box, the bottom of the fine filtering mechanism is provided with a collecting mechanism for automatically collecting the graphene after fine filtering, and the collecting mechanism is controlled by the self-weight change.
