Description

Technical Field

[0001] The utility model relates to the technical field of graphite production, in particular to a classification device for expandable graphite production. Background Art

[0002] Graphite crystals have a hexagonal network planar layered structure composed of carbon elements. The carbon atoms on the layer plane are bonded by strong covalent bonds, while the layers are bonded by van der Waals forces, which are very weak and the interlayer distance is relatively large. Therefore, under appropriate conditions, various chemical substances such as acids, alkali metals, and salts can be inserted into the graphite interlayers. When this interlayer compound is heated to an appropriate temperature, it can decompose instantaneously and rapidly, generating a large amount of gas, causing the graphite to expand axially into a worm-like new substance, that is, expandable graphite. This unexpanded graphite interlayer compound is expandable graphite.

[0003] However, in the prior art, there are many classification devices for expandable graphite production, such as the one disclosed in CN220496862U, which includes a machine shell. Input ports and a first discharge port are respectively provided at both ends of the machine shell. A rotating drum is arranged inside the machine shell, and both ends of the rotating drum are respectively located at the input port and the first discharge port. Classification holes are provided on the side wall of the rotating drum, and a second discharge port is arranged below the classification holes. Graphite enters the rotating drum through the input port. Through the rotation of the rotating drum, the graphite is affected by the guiding pieces and moves inside the rotating drum. When the graphite moves to the classification holes, under the influence of the guiding pieces, the graphite gradually contacts classification holes with larger and larger apertures, so as to perform multi-stage classification on it. The graphite that cannot be output is output through the first discharge port. However, there are the following problems in use:

[0004] In the above technology, when in use, expandable graphite is put into the machine shell, and the expandable graphite is classified and screened by the rotation of the rotating drum. However, the screening efficiency is slow only by the rotation of the rotating drum, which cannot meet the supply when the demand for expandable graphite is large, and it is necessary to manually put the expandable graphite into the rotating drum, resulting in a waste of human resources.

One end of the feed pipe 4 is fixedly connected to a sleeve 5. A first driving motor 6 is fixedly connected to the upper part of the sleeve 5. The driving end of the first driving motor 6 is fixedly connected to a spiral blade 7. The spiral blade 7 is arranged inside the sleeve 5 and is rotatably arranged above the bottom plate 1. When the spiral blade 7 rotates, the expandable graphite at the lower part of the sleeve 5 is transported to the upper part of the sleeve 5 and then discharged from the feed pipe 8. A feed pipe 8 is arranged on the outer wall of the sleeve 5. The feed pipe 8 is made of flexible material to prevent damage to the feed pipe 8 caused by the shaking of the machine body 9. One end of the feed pipe 8 is fixedly connected to the machine body 9. Three rows of fixing rods 10 are fixedly connected to the inner wall of the machine body 9. A first sieve plate 11, a second sieve plate 12, and a third sieve plate 13 are respectively arranged above the three rows of fixing rods 10. The fixing rods 10 play a supporting role for the first sieve plate 11, the second sieve plate 12, and the third sieve plate 13. The first sieve plate 11, the second sieve plate 12, and the third sieve plate 13 are arranged inside the machine body 9, and the pore diameters of the first sieve plate 11, the second sieve plate 12, and the third sieve plate 13 decrease in sequence.
