Description

Technical Field

[0001] The invention belongs to the technical field of graphene material processing, and in particular relates to a graphene safety production device. Background Art

[0002] As a new type of nanomaterial, graphene is widely used in electronic devices, energy storage, composite materials and other fields due to its excellent electrical conductivity, thermal conductivity, mechanical strength and chemical stability. However, some technical problems often occur in the preparation and processing of graphene, especially in the grinding, separation and transportation links.

[0003] For example, when traditional graphene grinding equipment is in operation, the impact force generated by the grinding cylinder at the moment of startup will cause a large load impact on the drive motor, which can easily cause motor damage or shorten the service life. In addition, the uneven distribution of particles during the grinding and grading process of graphene raw materials leads to unstable graphene quality. At the same time, since there is no effective partitioning device inside the grinding cylinder, graphene particles of different particle sizes are easy to mix together, and graphene materials with uniform particle sizes cannot be obtained.

[0069] In this embodiment, the design and use of a flexible connector 63 in a graphene safety production device are further optimized to improve the service life and work efficiency of the device.

[0073] The working principle of the present invention is:

[0074] When in use, the graphene raw material to be ground is put into the hopper 42, and the raw material in the hopper 42 enters the feed pipe 43 through the discharge port at the bottom thereof, and the second motor 44 drives the first auger shaft 45 located in the feed pipe 43 to rotate, and as the first auger shaft 45 rotates, the raw material falling into the feed pipe 43 is transported to the grinding cylinder 2;

[0075] The raw materials entering the grinding cylinder 2 will be ground as the grinding cylinder 2 rotates. After being ground to a suitable size, they will pass through a plurality of compartment plates 22 provided inside the grinding cylinder 2 in sequence. The compartment plates 22 can divide the inside of the grinding cylinder 2 into a plurality of grinding areas of different sizes.

[0076] As the grinding cylinder 2 rotates, the shovel bucket 23 will scoop up the ground materials. When the shovel bucket 23 with materials scooped up moves to the highest point, the materials in the shovel bucket 23 will fall into the receiving bucket 52. The third motor 53 drives the second auger shaft 54 ​​to rotate, and the materials in the receiving bucket 52 will be transported to the discharge pipe 51 and discharged through the discharge port 511.

[0077] At the moment of starting, the first motor 3 will first drive the driving gear 31 to rotate, and the driving gear 31 will mesh with the driven gear ring 62, thereby driving the driven gear ring 62 to rotate. At the moment of starting, the driven gear ring 62 will first pull the flexible connection member 63, and the flexible connection member 63 will be elastically deformed, and then the inner ring 61 will be driven to rotate through the flexible connection member 63. The inner ring 61 is fixed to one end of the grinding cylinder 2, so that as the inner ring 61 rotates, the grinding cylinder 2 can also rotate synchronously;

[0078] By providing the flexible connecting member 63, the first motor 3 can be protected at the moment when the grinding cylinder 2 is started, thereby reducing the damage to the first motor 3 at the moment when it is started.

[0079] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
