Embodiment 1

[0031] Such as figure 1 As shown, the cyclone separator with powder shaping function of the present invention includes a cylinder 1, a conical cylinder 2 arranged below the cylinder 1, and a powder discharge pipe at the bottom of the conical cylinder 2 5. An air inlet pipe 3 is provided along the tangential direction on the side of the cylinder body 1, and an air outlet pipe 4 coaxial with it is provided in the middle of the cylinder body 1; several parallel pipes are provided on the inner wall of the cylinder body 1. The first grinding line 11, the extension direction of the first grinding line 11 is perpendicular to the rotation direction of the airflow in the cyclone separator.

[0032] The cyclone separator with powder shaping function in this embodiment is mainly used for the shaping and separation of graphite particles widely used in the lithium battery field; the distance between the grinding line and the grinding line is 500 μm, and the grinding line The groove depth ...

Embodiment 2

[0035] The cyclone separator with the powder shaping function concurrently as in embodiment 1. The difference is: the entire outer wall of the air outlet pipe 4 is provided with helical blades 41 with a pitch of 100mm, and the extension direction of the helical blades 41 is the same as the rotation direction of the airflow coming in from the air inlet pipe 3 on the inner wall of the cylinder body 1. The same; the helical blade 41 is provided with a second graining line 411 , and the extending direction of the second graining line 411 is perpendicular to the direction of the airflow coming in from the air inlet pipe 3 . The distance between the grain lines of the second grain lines 411 is also 500 μm, and the groove depth between the grain lines is also 500 μm. Others are the same as embodiment 1.

[0036] Using the cyclone separator with powder shaping function of this embodiment, under the same conditions as in Example 1, the graphite particles are shaped and separated, and ...

Abstract

The invention discloses a cyclone separator with a powder shaping function. A first abrasive line (11) is arranged on the inner wall of a cylinder (1) of the cyclone separator, and the extension direction of the first abrasive line (11) does not coincide with the airflow rotation direction in the cyclone separator. According to the cyclone separator with the powder shaping function, the powder can be shaped in the powder separation process.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a cyclone separator with the function of shaping powder. Background technique [0002] Graphite electrodes are widely used in the field of lithium batteries, and the raw materials used in the preparation of the graphite electrodes are spherical or quasi-spherical powder particles with an average particle size of 35-45 μm. Due to its macroscopic isotropy and smooth surface, spherical or quasi-spherical graphite particles can reduce the bridging between particles, increase the bulk density, and improve the conductivity of graphite electrodes. If graphite particles have burr edges and corners, it will cause voids due to bridging between particles, which will affect the conductivity of graphite electrodes. [0003] However, during the processing of graphite, after the raw graphite ore is pulverized into a powder with a specified particle size, there are often burrs and...
