example 1

[0073] Example 1. In this embodiment, the second bottle body 613 is provided with several through holes, and the partition plate 68 is inserted into the through holes to separate the inner space of the second bottle body 613 . In this embodiment, the inner wall of the second bottle body 613 is axially spaced with several slots, and one end of the partition plate 68 is snapped into the slot by passing through the through hole, and the other end is sealed and connected with the through hole to realize the second The partition of the inner space of the bottle body 613. A movable rubber sealing ring is sheathed on the partition plate 68 , and the partition plate 68 realizes the sealing connection with the through hole through the rubber sealing ring. When blanking is required, the partition plate 68 can be pulled away.

example 2

[0074]Example 2: In this embodiment, the partition plate 68 may also be rotatably connected to the inner wall of the second bottle body 613 through a rotating shaft assembly. More specifically, the shaft assembly is connected to the partition plate 68, and one end of the shaft assembly is connected to the second bottle body 613, and the shaft assembly is connected to the micro-drive assembly at the same time. The rotation of the rotating shaft assembly can be driven by the micro-drive assembly, and the partition plate 68 is turned over by the rotation of the rotating shaft assembly, so that the material falls downward; in this case, the through hole is detachably connected with a sealing strip.

[0075] In this embodiment, one end of the first bottle body 612 is provided with a first connector, and one end of the second bottle body 613 is provided with a second connector adapted to the first connector. A sealing gasket is provided between the first connecting head and the seco...

Description

technical field [0001] The invention belongs to the technical field of preparation of wave-absorbing materials, and more specifically relates to a device for rapidly and efficiently preparing graphene magnetic powder. Background technique [0002] The magnetic particle absorbing material has the advantages of strong magnetic loss capability, simple preparation process, and low cost. However, its application frequency is limited, and its shortcomings such as high density, low dielectric loss, and poor oxidation resistance make it difficult to meet the impedance matching characteristics of absorbing materials. [0003] The preparation methods of graphene / magnetic particle materials mainly include physical methods and chemical methods. The physical methods mainly include high-energy mechanical mixing ball milling method and ultrasonic modification method, and there are many chemical preparation methods, such as hydrothermal synthesis method, chemical co-precipitation method, s...
