[0002] Graphene has excellent optical, electrical and mechanical properties and has important application prospects in materials science, micro-nano processing, energy, biomedicine, drug delivery, etc. It is considered a revolutionary material in the future. In the production process of graphene, generally, graphite ore is refined into graphite particles, and then the graphite particles are sprayed and the precipitation is made more open, so that the expanded graphite is easier to peel off. At present, in the process of pulverizing graphite particles, generally, a fluidized bed type steam kinetic energy mill is used to pulverize the graphite particles.

[0003] Traditional graphene steam kinetic energy mills usually do not have the air pressure function similar to that of a blower. Since blowers are usually used to provide high-pressure gas or air flow in industrial and manufacturing processes to drive equipment or perform processing operations. Then, without the air pressure function of the blower, it is difficult for materials to do work effectively for a long time, and the dispersibility of ultra-fine or fine powder materials is poor.

[0004] In view of the above problems, for this reason, a graphene steam kinetic energy mill with multiple nozzles and high pulverization effect is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a graphene steam kinetic energy mill with multiple nozzles and high pulverization effect, which solves the problems in the background technique that without the air pressure function of the blower, it is difficult for materials to do work effectively for a long time, and the dispersibility of ultra-fine or fine powder materials is poor.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A graphene steam kinetic energy mill with multiple nozzles and high pulverization effect, including a pulse collector, a blower is arranged on the right side of the pulse collector, a wind pressure blade turntable is arranged inside the blower, a main machine is installed at the lower air outlet of the blower, the upper air outlet of the blower is connected to the right side of the pulse collector through a classifier, and a feed inlet penetrates and is fixed in the middle of the right side of the main machine.

[0007] As a further description of the above technical scheme: Five groups of steam pipelines are arranged outside the main machine, and uniformly distributed inclined nozzles penetrate and are fixed above the five groups of steam pipelines, and one end of each inclined nozzle penetrates and is connected to the main machine. Steam inlets penetrate and are fixed on one side of the five steam pipelines. A hot air interface penetrates and is fixed at the top right of the pulse collector. A second thermocouple and a second pressure gauge penetrate and are installed above the classifier.

[0008] As a further description of the above technical solution: A storage hopper is arranged on the right side of the main machine. A second star-shaped discharge valve is installed at the lower discharge end of the storage hopper. The feeding port is connected to the discharge end of the second star-shaped discharge valve through a screw feeder.

[0009] As a further description of the above technical solution: Brackets are fixed on the outer sides of both the main machine and the storage hopper.

[0010] As a further description of the above technical solution: A screw conveyor is installed at the lower discharge end of the pulse collector. A first star-shaped discharge valve is installed at the discharge port of the screw conveyor.

[0011] As a further description of the above technical solution: A blower is arranged on the left side of the pulse collector. The air outlet end of the blower is connected to the left side of the pulse collector through a return air pipe. A silencer is installed at the connection between the blower and the return air pipe.

[0012] As a further description of the above technical solution: A first pressure gauge and a first thermocouple are respectively penetrated and installed above the return air pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The graphene steam kinetic energy mill with multiple nozzles and high pulverization effect provided by the present utility model mainly has four functions through the pressure blower. First, it pressurizes the air to enable the material to perform effective work for a longer time (realize the maximization of graphene preparation); second, it enhances the dispersibility of the ultrafine powder; third, compared with the classifier, it is easier to make the material finer, and the maximum particle size can be controlled within 500 nanometers; fourth, when it is finer, the output increases, which is of great significance for the preparation of pure graphene powder. All wearing parts of this pressure blower are made of wear-resistant ceramics.

[0015] 2. The graphene steam kinetic energy mill with multiple nozzles and high pulverization effect provided by the present utility model can also reduce the average particle size of the exfoliated graphene carrier particles to 120 - 150 nanometers (graphene is coated on the carrier in a single-layer form) through the pressure blower, and the maximum particles can be reduced to 500 nanometers through the final classification.

[0016] 3. The graphene steam kinetic energy mill with multiple nozzles and high pulverization effect provided by the present utility model can generate a double-vortex air cyclone layer in the steam pipelines from the fourth to the fifth layer through the pressure blower. Therefore, the requirements for the inclined nozzles are higher compared with the equipment without a pressure blower. The more and smaller the inclined nozzles are, the greater the pressure, and the more obvious the pulverization effect and the graphene preparation effect will be.

[0017] 4. A graphene steam kinetic mill with multiple nozzles and high pulverization effect provided by the present utility model injects steam into the steam pipeline through the steam inlet, and then enters the main body through the obliquely installed nozzles. At the same time, the speed and the size of the kinetic energy steam beam are controlled through the obliquely installed nozzles to achieve the rapid treatment of graphite fine powder and the gas combination of polymer materials; at the same time, the large particles are suppressed from rising rapidly and kept at the bottom layer to continuously do work, protecting the raw materials at the inlet from quickly entering the eddy current layer for treatment when entering the bottom layer, and maximizing the functional effect.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings.

[0026] Refer to Figures 1 - 5, a graphene steam kinetic energy mill with multiple nozzles and high pulverization effect of the present utility model, includes a pulse collector 1. A pressure blower 13 is arranged on the right side of the pulse collector 1. A pressure air blade turntable 21 is arranged inside the pressure blower 13. The lower air outlet of the pressure blower 13 is installed with a main machine 14. The upper air inlet of the pressure blower 13 is connected to the right side of the pulse collector 1 through a classifier 12. A feed inlet 23 penetrates and is fixed in the middle of the right side of the main machine 14. Five groups of steam pipelines 15 are arranged outside the main machine 14. Uniformly distributed inclined nozzles 22 are penetrated and fixed above the five groups of steam pipelines 15. One ends of the inclined nozzles 22 all penetrate the main machine 14 and are connected thereto. The five groups of steam pipelines 15 are divided into upper and lower parts. Among them, the upper part has three layers, and the lower part has two layers or more. Steam inlets 20 are penetrated and fixed on one side of the five groups of steam pipelines 15.

[0027] The right topmost part of the right side of the pulse collector 1 penetrates and is fixed with a hot air interface 9. A second thermocouple 10 and a second pressure gauge 11 are respectively penetrated and installed above the classifier 12.

[0028] A storage hopper 16 is arranged on the right side of the main machine 14. A second star-shaped discharge valve 18 is installed at the lower discharge end of the storage hopper 16. The feed inlet 23 is connected to the discharge end of the second star-shaped discharge valve 18 through a screw feeder 17.

[0029] Supports 19 are fixed on the outer sides of the main machine 14 and the storage hopper 16.

[0030] 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 outlet of the screw conveyor 8.

[0031] A blower 6 is arranged on the left side of the pulse collector 1. The air outlet end of the blower 6 is connected to the left side of the pulse collector 1 through a return air duct 2. A silencer 5 is installed at the connection between the blower 6 and the return air duct 2.

[0032] A first pressure gauge 3 and a first thermocouple 4 are respectively penetrated and installed above the return air duct 2.

[0033] Specific implementation manner: Graphene is conveyed into the main machine 14 through the storage hopper 16 by the screw feeder 17, and the feeding amount is controlled by the second star-shaped discharge valve 18 during the feeding process. At the same time, steam is injected into the steam pipeline 15 through the steam inlet 20, and then enters the interior of the main body 14 through the 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. (The number of steam inlets is equal to the number of layers of the steam pipeline 15). In the middle is the air compressor 13, which compresses air to enable the material to perform effective work for a longer time (to maximize the preparation of graphene); to enhance the dispersibility of the ultra-fine powder; compared with the classifier 12, it is easier to make the material finer, and the maximum particle size can be controlled within 500 nanometers; therefore, when the material is finer, the output increases, which is of great significance for the preparation of pure graphene powder; the upper part is the classifier 12. The qualified products of the particles are finally centrally collected in the pulse collector 1 after classification, while the unqualified products of the particles are pressed back into the main machine 14 for continuous peeling. During the classification process, the effective suppression of the material can be achieved by controlling the air volume of the air compressor 13, realizing the maximum reverse effect on the material, making the carrier material carrying graphene itself become finer and finer, maximizing the effect of peeling graphite into graphene, and then the finished raw materials are uniformly sent through the screw conveyor 8. By opening the blower 6, the wind blows into the pulse collector 1, so that the internal material is sent into the finished product bin, and finally the purified clean gas is discharged through the outlet of the silencer 5.
