The utility model belongs to the technical field of
graphene composite material preparation, and particularly relates to a
powder graphene lossless adding device, a main body structure comprises a
piston pump, a material cabinet and a filling gun, the material cabinet and the filling gun are respectively connected with the
piston pump, and the
piston pump is connected with the material cabinet through a suction pipeline and connected with the filling gun through a
discharge pipeline. The material cabinet is provided with a sealing cover, a filter screen and a swinger driven by a motor, the
piston pump structurally comprises a piston and an electro-hydraulic push-pull device connected with the piston, the filling gun is provided with a control trigger, the suction pipeline and the
discharge pipeline are both connected with the adjustable
constant pressure valve, and the sealing cover of the material cabinet is made of
silica gel materials. The flexible pipes in the suction pipeline and the
discharge pipeline are oil-resistant and acid-alkali-resistant PE high-strength flexible pipes, continuous and lossless addition of
graphene is achieved through
reciprocating motion of a piston in the
piston pump, loss, environmental
pollution and potential safety hazards in the graphene adding process can be eliminated, and powerful support is provided for large-scale production of graphene composite materials. The device is simple in structure, safe, environment-friendly and convenient to operate.
