Description
Technical Field
The invention belongs to the technical field of machinery, and particularly relates to a cyclone separator with a powder shaping function.
Background
Graphite electrodes are widely used in the field of lithium batteries, and spherical or spheroidal powder particles having an average particle diameter of 35 to 45 μm are used as a raw material for preparing the graphite electrodes. The spherical or spheroidal graphite particles have the macroscopically isotropic property and smooth surfaces, so that bridging among the particles can be reduced, the apparent density is improved, and the conductivity of the graphite electrode is improved. If the graphite particles have burr edges, cavities can be formed due to bridging among the particles, and the conductivity of the graphite electrode is affected.
However, in the processing of graphite, since a raw graphite ore is often subjected to burr edges after being pulverized into powder having a predetermined particle size by a pulverizer, it is necessary to shape the raw graphite ore to remove the burr edges. The prior art generally uses the crushing hammer head with a shaping effect to crush and shape graphite particles by carrying out morphology control on the graphite particles, and the patent CN109794324A uses a hammer head with an arc-shaped surface, a spherical surface and a plane to shape the graphite particles. However, the crushing hammer head is more and more complex to make, and the effect of shaping particles by using the crushing hammer head with the shaping function cannot be achieved; through detection, part of the crushed and shaped graphite particles still have a small number of burr edges and corners, and adverse effects are brought to subsequent use of the graphite particles.
In the powder industry, for example, continuous industrial production of graphite powder is also generally performed, and the powder is continuously transferred from one processing device to another processing device by a pneumatic conveying device, and before entering another processing device, gas-solid separation is often required to separate the graphite powder from the carrier gas.
A cyclone separator is a device for separating solid particles from an air flow by using the principles of gravity settling, centrifugal settling, cyclone separation and the like. The principle is that after gas carrying solid particles enters a cyclone separator from the tangential direction, the gas can rotate at high speed along the wall of the separator and make downward spiral motion to the bottom of the separator according to a spiral route to form downward spiral gas flow on the outer layer, the gas turns upwards after reaching the bottom to form upward spiral gas flow on the inner layer, and then the upward spiral gas flow is discharged from an exhaust port of the cyclone separator; and the solid particles are thrown onto the inner wall of the cyclone separator and slide down along the inner wall under the action of centrifugal force, are collected in the conical barrel below the cyclone separator and leave from the powder discharge pipe below the conical barrel, so that the aim of solid-gas separation is fulfilled. The cyclone separator in the prior art generally only plays a role in solid-gas separation.
The cyclone separator is designed into the cyclone separator with the powder shaping function for the first time, and the pulverized powder such as graphite particles are shaped in the separation process of the cyclone separator, so that the graphite particles are shaped into spheres or similar spheres.

As shown in fig. 1, the cyclone separator with powder shaping function of the present invention comprises a cylinder 1, a conical cylinder 2 arranged below the cylinder 1, and a powder discharge pipe 5 arranged at the lower part of the conical cylinder 2, wherein an air inlet pipe 3 is arranged at the side part of the cylinder 1 along the tangential direction, and an air outlet pipe 4 coaxial with the air inlet pipe is arranged at the middle part of the cylinder 1; a plurality of parallel first grinding lines 11 are arranged on the inner wall of the cylinder body 1, and the extending direction of the first grinding lines 11 is vertical to the rotating direction of the airflow in the cyclone separator.
The cyclone separator with the powder shaping function is mainly used for shaping and separating graphite particles of graphite electrodes widely used in the field of lithium batteries; the distance between the grinding lines is 500 μm, and the groove depth between the grinding lines is 500 μm. Wherein the height of the cylinder body 1 of the cyclone separator is 800mm, and the length-diameter ratio is 4: 2; the air inlet pipe 3 is a rectangle with the diameter of 100mm multiplied by 50mm, the length of the air outlet pipe 4 is 1200mm, and the inner diameter is 207 mm; the height of the conical cylinder body 2 is 800mm, and the inner diameter of the ash discharge opening of the conical cylinder body 2 is 100 mm.
The cyclone separator with powder shaping function of the embodiment is used for shaping and separating graphite particles, the air inlet speed at the air inlet pipe is 4m/s, and the carrier gas powder content is 15g/dm3As a result, as shown in fig. 4, it can be seen from fig. 4 that the graphite particles passing through the cyclone separator having the powder reforming function of the present example have substantially no burr edges.
Example 2
A cyclone separator having a powder shaping function similar to that of example 1. The difference is that: the outer wall of the whole air outlet pipe 4 is provided with spiral blades 41 with the pitch of 100mm, and the extension direction of the spiral blades 41 is the same as the rotation direction of the airflow coming from the air inlet pipe 3 on the inner wall of the cylinder 1; the spiral blade 41 is provided with a second grinding line 411, and the extending direction of the second grinding line 411 is perpendicular to the direction of the air flow entering the air inlet pipe 3. The pitch between the ground lines of the second ground line 411 is also 500 μm, and the groove depth between the ground lines is also 500 μm. The rest is the same as example 1.
The cyclone separator having the powder-shaping function of the present example was used to shape and separate graphite particles under the same conditions as in example 1, and the results are shown in fig. 5. As can be seen from fig. 5, the graphite particles treated by the cyclone separator with powder reshaping function of this embodiment are obviously spherical or spheroidal, and the graphite particles obviously have no burr edges; the effect is significantly better than that of the graphite particles obtained in example 1.
Comparative example
The cyclone separator of the same example 1 was a general cyclone separator, and the inner wall of the cylinder 1 had no abrasive grain lines and was a general smooth inner wall. The other conditions were the same as in example 1.
The graphite particles were separated using the general cyclone of this comparative example under the same conditions as in example 1, and the results are shown in fig. 3. As can be seen from fig. 3, the graphite particles separated by the conventional cyclone separator of the present comparative example substantially maintained the shape immediately after pulverization, and the burr edges and corners of the graphite particles were very noticeable. The cyclone separator of the comparative example only has the gas-solid separation function and has no shaping effect on graphite particles.
