Description

Technical Field

[0001] This utility model relates to the field of graphene dispersing technology, specifically to a dispersing device for graphene preparation. Background Technology

[0002] Graphene is a type of poly(phosphorus) 2 A novel material consisting of hybridized carbon atoms tightly packed into a single-layer two-dimensional honeycomb lattice structure, graphene is prone to agglomeration during its preparation. This agglomeration not only affects the dispersibility and uniformity of graphene but may also reduce its performance and application effectiveness. Therefore, a dispersing device uses mechanical force to break up and disperse the graphene raw materials or intermediates, making the graphene particles more uniform and finer. This helps improve the dispersibility and uniformity of graphene in subsequent preparation processes, thereby enhancing its performance and application effectiveness.

[0003] Existing dispersing devices may not be able to completely break down these agglomerates and cannot fully and thoroughly break down graphene particles, resulting in agglomerate residues. These agglomerates may be difficult to disperse in subsequent applications, affecting the performance of graphene.

[0004] For example, the patented patent CN219482257U discloses a pre-dispersion device for graphene processing slurry. This patent mainly relies on a dispersion mechanism to stir and disperse the graphene slurry. However, for tightly aggregated graphene particles, it may not be able to provide sufficient shear force and impact force to completely break the agglomerates. In order to achieve a certain dispersion effect, the device may need to run for a long time or increase the stirring speed, which will result in high energy consumption.

[0005] Therefore, it is necessary to invent a dispersing device for graphene preparation to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a dispersing device for graphene preparation, in order to solve the problem that the technology cannot completely break up these agglomerates and cannot fully and thoroughly break up the graphene particles, resulting in agglomerate residue.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dispersing device for graphene preparation, comprising a crushing box and a dispersing box. The crushing box is equipped with a crushing mechanism inside, and a feeding inclined plate is provided at the bottom of the crushing box. A dispersing box is provided on one side outside the crushing box, and a box cover is hinged to the top of the dispersing box. A high-speed dispersing mechanism is provided inside the dispersing box. The high-speed dispersing mechanism includes a rotating shaft, which is rotatably mounted inside the dispersing box through a bearing. Multiple dispersing blades are provided around the outer wall of the rotating shaft. The dispersing blades are designed with a blade structure. A second motor is provided on one side outside the dispersing box and located on a vertical frame. The output end of the second motor is connected to the rotating shaft.

[0008] Preferably, a support frame is provided at the bottom of the crushing box, and a feed inlet is provided at the top of the crushing box, which facilitates the introduction of the graphene raw material to be crushed into the crushing box.

[0009] Preferably, the crushing mechanism includes a first crushing roller and a second crushing roller, which are arranged in parallel inside the crushing box. The roller surfaces of the first and second crushing rollers cooperate with each other. The parallel arrangement and mutual cooperation of the roller surfaces of the first and second crushing rollers can effectively squeeze and shear the graphene raw material, thereby achieving the purpose of crushing.

[0010] Preferably, the crushing mechanism further includes a driving gear and a driven gear. The driving gear is connected to the shaft end of the second crushing roller, and the driven gear is connected to the shaft end of the first crushing roller. The driving gear and the driven gear mesh with each other to form a gear transmission pair. The meshing of the driving gear and the driven gear ensures that the first crushing roller and the second crushing roller can rotate synchronously in opposite directions, thereby improving the crushing effect.

[0011] Preferably, a No. 1 motor is provided on one side of the drive gear, and the output end of the No. 1 motor is connected to the drive gear through a coupling. The No. 1 motor provides a power source for the crushing mechanism, and the connection with the drive gear through the coupling ensures the effective transmission of power.

[0012] Preferably, the feeding inclined plate has multiple feeding holes, and the bottom end of the feeding inclined plate is tightly connected to a feeding hopper. The top opening of the feeding hopper is precisely aligned with the multiple feeding holes. The feeding hopper is designed in a conical shape, which facilitates the centralized collection and subsequent processing of materials and improves feeding efficiency.

[0013] Preferably, the feeding end of the feeding hopper is connected to a discharge pipe, and the feeding end of the discharge pipe is provided with a collection box located on the upright frame. The feeding hopper and the discharge pipe are connected, and the setting of the discharge pipe realizes the connection between the feeding hopper and the collection box, which facilitates the collection of the crushed graphene particles.

[0014] Preferably, the bottom surface of the dispersion box is provided with multiple discharge holes, and a movable collection box is provided at the bottom of the outer side of the dispersion box. The feed end of the top of the movable collection box is aligned with the multiple discharge holes. The discharge holes facilitate the dispersed graphene particles to fall into the movable collection box. The design of the movable collection box allows the dispersed material to be flexibly collected and stored, which is convenient for subsequent processing or transportation.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This invention employs a crushing mechanism and a high-speed dispersion mechanism. The crushing mechanism uses mechanical force to initially crush and disperse the graphene raw material, primarily targeting larger agglomerates and particles. However, due to the interlayer forces and agglomeration characteristics of graphene, some smaller agglomerates or incompletely dispersed particles may escape the crushing action of the crushing mechanism. At this point, the high-speed dispersion mechanism acts as a second line of defense, using high shear force and impact force to further disperse these remaining particles, ensuring that all agglomerated graphene raw materials are thoroughly dispersed. This dual dispersion mechanism significantly improves the dispersion effect of graphene. Through the continuous action of initial and fine dispersion, the particle size distribution of graphene particles becomes more uniform, and agglomeration is effectively suppressed, thereby improving the dispersibility and reinforcing effect of graphene in composite materials.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The diagram shows a dispersing device for graphene preparation, comprising a crushing box 1 and a dispersing box 10. The crushing box 1 has a crushing mechanism 4 inside and a feeding inclined plate 5 at its bottom. The dispersing box 10 is located on one side of the crushing box 1. A box cover 11 is hinged to the top of the dispersing box 10. A high-speed dispersing mechanism 12 is located inside the dispersing box 10. The high-speed dispersing mechanism 12 includes a rotating shaft 1201, which is rotatably mounted inside the dispersing box 10 via bearings. Multiple dispersing blades 1202 are arranged around the outer wall of the rotating shaft 1201. The dispersing blades 1202 have a blade structure design. A second motor 1203 is located on a support frame 2 on one side of the dispersing box 10. The output end of the second motor 1203 is connected to the rotating shaft 1201. Multiple discharge holes 13 are opened on the bottom surface of the dispersing box 10. A movable collection box 14 is located at the bottom of the dispersing box 10, with the feed end of the movable collection box 14 aligned with the multiple discharge holes 13.

[0026] In this embodiment, the high-speed dispersion mechanism 12 generates high shear force and impact force through the rotation of the rotating shaft 1201 and the dispersion blade 1202, which further disperses the graphene particles and improves the dispersion effect. As a result, the dispersed graphene particles fall from the discharge hole 13 on the bottom surface of the dispersion box 10 into the mobile collection box 14 for collection. The design of the mobile collection box 14 allows for flexible collection and storage of the dispersed material.

[0027] A support frame 2 is provided below the crushing box 1, and a feed inlet 3 is provided at the top of the crushing box 1. The crushing mechanism 4 includes a first crushing roller 401 and a second crushing roller 402, which are arranged parallel to each other inside the crushing box 1. The roller surfaces of the first crushing roller 401 and the second crushing roller 402 cooperate with each other. The crushing mechanism 4 also includes a driving gear 403 and a driven gear 404. The driving gear 403 is connected to the shaft end of the second crushing roller 402, and the driven gear 404 is connected to the shaft end of the first crushing roller 401. Driven gears 404 mesh with each other to form a gear transmission pair. A No. 1 motor 405 is provided on one side of the driving gear 403. The output end of the No. 1 motor 405 is connected to the driving gear 403 through a coupling. Multiple discharge holes 6 are provided on the discharge sloping plate 5. The bottom end of the discharge sloping plate 5 is tightly connected to the discharge hopper 7. The top opening of the discharge hopper 7 is precisely aligned with the multiple discharge holes 6. The discharge hopper 7 is designed in a conical shape. The discharge end of the discharge hopper 7 is connected to the discharge pipe 8. The discharge end of the discharge pipe 8 is provided with a collection box 9 and is located on the upright frame 2. The discharge hopper 7 is connected to the discharge pipe 8.

[0028] In this embodiment, the cooperation between the No. 1 crushing roller 401 and the No. 2 crushing roller 402 achieves effective compression and shearing crushing of graphene raw materials, improving the crushing effect. The design of the drive gear 403 and the No. 2 crushing roller 402 ensures that the No. 1 crushing roller 401 and the No. 2 crushing roller 402 can rotate synchronously in opposite directions, improving crushing efficiency and stability. The feeding inclined plate 5 can filter and screen the graphene in an agglomerated state that has not been dispersed by the crushing mechanism 4, so that the crushed graphene particles can fall evenly and smoothly. The crushed graphene particles are collected by the collection box 9, and those left on the feeding inclined plate 5 will be sent into the dispersion box 10 for secondary dispersion under the action of inertia. Thus, the structural design of this embodiment achieves efficient crushing and dispersion of graphene raw materials through the synergistic effect of the crushing mechanism 4 and the high-speed dispersion mechanism 12.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual appendix Figure 1-4When using this invention, firstly, start the first motor 405, which drives the drive gear 403 to rotate. Then, introduce the graphene raw material to be crushed into the crushing box 1. The drive gear 403 and the driven gear 404 form a gear transmission pair, which drives the first crushing roller 401 and the second crushing roller 402 to rotate synchronously in opposite directions. Therefore, the roller surfaces of the first crushing roller 401 and the second crushing roller 402 cooperate with each other to squeeze and shear the graphene raw material, achieving preliminary crushing and dispersion. The preliminarily crushed graphene particles... The particles fall through multiple feeding holes 6 on the feeding inclined plate 5. The feeding inclined plate 5 can filter and screen the agglomerated graphene that has not been fully dispersed by the crushing mechanism 4, so that the crushed graphene particles can fall evenly and smoothly. The initially crushed graphene particles falling through the feeding inclined plate 5 are collected by the feeding hopper 7 and then fall into the collection box 9 through the discharge pipe 8. The agglomerated graphene particles left on the feeding inclined plate 5 are sent into the dispersion box 10 for secondary dispersion under the action of inertia or the push of subsequent particles.

[0031] Refer to the instruction manual appendix Figure 5 When using this utility model, the second motor 1203 is then started. The second motor 1203 drives the rotating shaft 1201 and the dispersing blade 1202 to rotate. The rotation of the rotating shaft 1201 and the dispersing blade 1202 generates high shear force and impact force, which further disperses the agglomerated graphene particles that have entered the dispersing box 10. Through the continuous action of the high-speed dispersing mechanism 12, the particle size distribution of the graphene particles becomes more uniform, and the agglomeration phenomenon is effectively suppressed. The dispersed graphene particles fall from multiple discharge holes 13 on the bottom surface of the dispersing box 10 and are collected and stored by the mobile collection box 14.
