[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

[0023] Refer to Figures 1-5 , a low-cost graphene steam kinetic energy mill for rapid classification of the present invention includes a pulse collector 1. A upper main machine 13 is arranged on the right side of the pulse collector 1. First flanges 17 are fixed at both the top and bottom of the upper main machine 13. An extended main machine 18 is arranged below the upper main machine 13. Second flanges 19 are fixed at both the top and bottom of the extended main machine 18. The second flange 19 at the top of the extended main machine 18 is connected to the adjacent first flange 17 by nuts and bolts. A plurality of steam pipelines 14 are arranged outside the upper main machine 13, and a group of steam pipelines 14 are also arranged outside the extended main machine 18. Uniformly distributed inclined nozzles 16 are penetrated and fixed above the steam pipelines 14, and the inclined nozzles 16 respectively penetrate and are connected to the upper main machine 13 and the extended main machine 18. Steam inlets 15 are penetrated and fixed on one side of the steam pipelines 14. The upper main machine 13 is connected to the pulse collector 1 through a classifier 12 above.

[0024] It should be noted that the steam pipeline 14 is divided into two parts, and from bottom to top, they can be the first layer, the second layer, the third layer, the fourth layer, and the fifth layer and above respectively. The uppermost part is the classifier 12;

[0025] Among them: The main function of the first layer is the rapid pulverization layer, which can quickly prepare materials within 40 microns (the carrier for exfoliating graphene) to about D50 of 1 micron. For example, taking a diameter of 1m as an example, more than 4 nozzles are used, and the nozzle size requirement is more than 2mm. In this design, 8mm is adopted;

[0026] The main function of the second layer is to accelerate the pulverization effect, realize the rapid treatment of graphite micropowder and the gas combination of polymer materials and carrier materials, and at the same time suppress the rapid rise of large particles, protect the raw materials at the inlet to be quickly processed when entering the bottom layer, and maximize the functional effect;

[0027] One of the main functions of the third layer is to feed materials, and it is also a convection reverse action layer. Larger particles of the material can be quickly formed into a vortex effect. Those that cannot withstand the vortex effect will quickly enter the laminar flow layer, and after a certain reaction efficiency in the laminar flow layer, they will be quickly transferred to the parallel vortex layer for ultra-fine pulverization; its role of connecting the preceding and the following is very obvious;

[0028] The fourth layer is the vortex manufacturing layer with an upward rotation angle. Due to the huge polymerization effect at the lower limit, a large amount of ultra-fine powder is aggregated after being pulverized by the bottom layer. The finer the powder, the more difficult it is to pulverize (mainly because it is impossible to capture and do work on it), and the micro-variation effect becomes very important. Creating a vortex effect can greatly solve this problem, so as to perform sonic boom treatment on the material through the formation of an upward vortex flow, and at the same time maximize the role of fluid mechanics;

[0029] The fifth layer is the vortex manufacturing layer with a downward rotation angle, mainly to cope with the re-action of the ultra-vortex cohesion force at the downward rotation angle, so that the action of the vortex force forms a new acting force, and the super-kinetic energy release effect of the steam reaches the extreme;

[0030] The sixth layer is the airtight digestion layer, which further optimizes the super-powerful acting force, so that the average particle size of the carrier material particles is about 120 - 150 nanometers, and the maximum particle size of the carrier material is about 900 - 980 nanometers;

[0031] The classifier effectively suppresses the material through the control of the air volume, realizes the maximum reverse action on the material, makes the carrier material carrying graphene itself become finer, and maximizes the effect of exfoliating graphite into graphene.

[0032] Therefore, the inclined nozzles 16 on the first-layer steam pipeline and the second-layer steam pipeline can quickly process the product of the raw material for exfoliating graphene with barium sulfate as the carrier and a particle size of 44 microns passing through completely, so that the maximum particle size Dmax of the product is within 10 microns, and D50 is within 1 micron. At the same time, the carrier material, the compounded graphite and plastics (particles or plastic recycled materials reach the nanoscale, with an average particle size of 20 - 50 nanometers) can achieve the nano or ultra-nano level and be completely coated on the carrier. After the material is processed in the first layer and the second layer, it enters the feeding system layer, that is, the third layer (the third layer and the fourth layer are double-vortex cyclone layers, and the requirements for the nozzles are divided into three parts: size, angle and design method are extremely high. The smaller the nozzle, the more obvious the crushing effect and the graphene preparation effect under greater pressure). It can accelerate the appearance of carrier materials with a particle size of 100 nanometers. After compounding graphite, the maximum particle is less than 5 microns. The fourth layer and the fifth layer form a relatively closed kinetic energy layer. The main function of the fourth-layer kinetic energy layer is to create a high-speed kinetic energy upper vortex flow effect and increase the characteristic effect of the steam kinetic energy of the lower two layers, so that the materials of the lower two layers are concentrated for sonic boom and ultra-high-speed physical property treatment, realizing the special effect function of preparing graphene from graphite. The fifth layer not only protects the stable operation of the lower four layers, but also plays a great accelerating force, so that the energy release is maximized, and the maximum particle size of the carrier material is controlled within 3 microns. The higher the proportion of graphene content. The sixth layer is the stratosphere, which re-accelerates all forces, greatly improving the average particle size, reducing it from 600 nanometers to 400 nanometers. In addition, it should be noted that only five layers are shown in this drawing. If more layers are needed, the extended main machine 13 can be spliced through a flange and locked and fixed with bolts and nuts. For details, please refer to the appendix Figure 3 , and expand downwards accordingly, and expand specifically according to actual needs.

[0033] At the top right side of the pulse collector 1, a hot air interface 9 penetrates and is fixed. Above the classifier 12, a second thermocouple 10 and a second pressure gauge 11 penetrate and are installed respectively.

[0034] A storage hopper 20 is arranged on the right side of the upper main machine 13. A second star-shaped discharge valve 21 is installed at the lower discharge end of the storage hopper 20. A feed inlet 24 penetrates and is fixed on the right side of the upper main machine 13. The feed inlet 24 is connected to the discharge end of the second star-shaped discharge valve 21 through a screw feeder 23.

[0035] Supports 22 are fixed on the outer sides of both the upper main machine 13 and the storage hopper 20.

[0036] A screw conveyor 8 is installed at the lower discharge end of the pulse collector 1. A first star-shaped discharge valve 7 is installed at the discharge port of the screw conveyor 8.

[0037] A blower 6 is provided on the left side of the pulse collector 1. The air outlet end of the blower 6 is connected to the pulse collector 1 through a return air pipe 2, and a silencer 5 is installed at the connection between the blower 6 and the return air pipe 2.

[0038] A first pressure gauge 3 and a first thermocouple 4 are respectively penetrated and installed above the return air pipe 2.

[0039] Graphene is conveyed into the upper main machine 13 through a spiral feeder 23 by a storage hopper 20, and the feeding amount is controlled by a second star-shaped discharge valve 21 during the feeding process. At the same time, steam is injected into the steam pipe 15 through a steam inlet 20, and then enters the interior of the main body 14 through an inclined nozzle 22. At the same time, the speed and the size of the kinetic energy steam beam are controlled through the inclined nozzle 22 to enable the material to perform effective work for a longer time. After the work is completed, it enters a classifier 12. The qualified products after classification are finally centrally collected in the pulse collector 1, while the unqualified products are pressed back into the upper main machine 13 for continuous peeling, and then the finished raw materials in the pulse collector 1 are uniformly sent to the finished product bin by a screw conveyor 8 through the opening of the blower 6, so that the wind blows into the pulse collector 1, thereby enabling the internal material to be sent into the finished product bin. Finally, the purified clean gas is discharged through the outlet of the silencer 5.
