Description

Technical Field

[0002] In the prior art, metals are mixed with other materials by powder metallurgy, which produces metal powder or a mixture of metal powder and non-metallic powder as raw material, and then forms and sinters them to produce metal materials, composite materials and various types of products.

[0003] The above technologies have the problem of poor dispersion between different materials, especially the composite of graphene materials and metal materials. Currently, the most commonly used method for preparing graphene / metal composite materials is powder metallurgy, which includes the following methods:

[0004] 1. Powder mixing method: Mechanically mixing graphene with metal powder will cause graphene to agglomerate, making it difficult to completely disperse the graphene and metal powder evenly.

[0005] 2. Wet mechanical stirring and mixing: graphene and metal powder are mechanically stirred and mixed in an organic solvent, and the dispersion uniformity is poor.

[0006] 3. Surface modification and charge attraction method: by adding surfactants to improve the dispersibility of graphene and metal powder and the stability of the solution, the dispersion uniformity is poor.

[0007] 4. Ball milling method: The structure of graphene is often destroyed, thereby reducing the effect of graphene on improving the performance of composite materials. Summary of the Invention

[0039] The inert gas production equipment 2 is generally a gas generator, which is used to prepare inert gas.

[0040] Generally, the inert gas produced by the inert gas production equipment 2 is temporarily stored in the gas storage device 3 .

[0041] The inert gas storage device 1 and the inert gas production equipment 2 complement each other to ensure that the amount of inert gas can meet the use demand. Of course, only the inert gas storage device 1 or the inert gas production equipment 2 and the gas storage device 3 can be provided.

[0042] The material adding device is used to add material, and the material may be, for example, graphene powder or a dispersion formed by graphene powder, a swelling agent, an organic solvent, and the like.

[0043] The material adding device is a hopper 41 , through which the configured materials are directly added.

[0044] The material adding device may further include a powder adding device 44, a stirrer 43, a liquid tank 42, and a hopper 41 for preparing the materials. The powder adding device 44 is used to add powder, the liquid tank 42 is used to add liquid, and the stirrer 43 is used to stir the powder and liquid in the hopper 41.

[0045] The material adding device includes a gas interface for receiving inert gas. The gas interface is connected to the inert gas storage device 1 or the gas storage device 3. The inert gas enters the material adding device through the gas interface and flushes the material in the material adding device to the conveying pipeline 12.

[0046] The conveying pipeline 12 is connected to the material adding device and is used to convey the inert gas and materials.

[0047] A dryer 5 , a flow rate regulating device 6 , an ultrasonic processor 7 , an elastic energy storage bag 8 and a switch element 9 are sequentially arranged on the conveying pipeline 12 .

[0048] The dryer 5 is used to dry the material.

[0049] The flow rate regulating device 6 is used to regulate the flow rate of the inert gas and material in the conveying pipeline 12.

[0050] The ultrasonic processor 7 is used to pre-disperse the material.

[0051] The elastic energy storage bag 8 is used to temporarily store inert gas and materials to increase the impact force during injection.

[0052] The elastic energy storage pack 8 includes an air inlet pipe 84, an air outlet pipe 83, and an elastic air storage sidewall. The elastic air storage sidewall comprises an upper sidewall 81 and a lower sidewall 82. Of course, the elastic air storage sidewall can also be a single unit. In this embodiment, the air inlet pipe 84 is located on the upper sidewall 81, and the air outlet pipe 83 is located on the lower sidewall 82. The air inlet pipe 84 extends into the air storage cavity and is adjacent to the air outlet pipe 83.

[0053] The switch element 9 is generally a solenoid valve and is in a normally closed state. The switch element 9 is controlled to open when the internal pressure of the elastic energy storage pack 8 reaches a set pressure.

[0054] Specifically, the device has a controller, and a pressure detection unit is set in the elastic energy storage bag 8. The pressure detection unit detects the pressure of the elastic energy storage bag 8. When the pressure of the elastic energy storage bag reaches a set value, the controller controls the switch element 9 to open.

[0055] The injector 10 is connected to the end of the conveying pipeline 12 and is used to inject the inert gas and material in the conveying pipeline 12 into the molten metal.

[0056] The melting device 11 is used to melt metal. The melting device 11 can be a furnace or other equipment. When the melting device 11 melts the metal, a protective gas is filled into the melting device 11.

[0057] This embodiment includes a stirrer 14 for stirring the molten metal to facilitate sufficient dispersion of the material in the molten metal. The stirrer 14 has a driving motor.

[0058] The agitator 14 and the ejector 10 are designed to be liftable.

[0059] In order to improve the spraying effect of the material, the present embodiment designs the sprayer.

[0060] Specific as Figure 5-7 As shown, the injector 10 is conical in shape, including an apex, a conical surface, and a bottom surface.

[0061] The ejector 10 comprises a plurality of conical cylinders nested together, of course, the innermost layer being a cone.

[0062] The outer diameter of the inner conical cylinder 101 matches the inner diameter of the outer conical cylinder 102. A plurality of channels 103 are formed between the inner conical cylinder 101 and the outer conical cylinder 102 for the inert gas and materials to pass through.

[0063] Preferably, the channel 103 is a curve. Specifically, a curved groove is formed on the outer surface of the inner conical cylinder 101 and the inner surface of the outer conical cylinder 102. The curved grooves on the outer surface of the inner conical cylinder 101 and the inner surface of the outer conical cylinder 102 are connected to form the channel 103.

[0064] Of course, the curved groove may be formed only on the outer surface of the inner conical tube 101, and the inner surface of the outer conical tube 102 may be a smooth conical surface; or the curved groove may be formed on the inner surface of the outer conical tube 102, and the outer surface of the inner conical tube 101 may be a smooth conical surface.

[0065] In this embodiment, a clamping claw 104 is provided on the outer surface of the inner conical cylinder 101, and an L-shaped clamping groove 105 is provided on the inner surface of the outer conical cylinder 102. The clamping claw 104 is installed in the clamping groove 105 and rotated to achieve fixed assembly of the two.

[0066] Of course, adjacent conical cylinders can also be fixed together by welding or interference fit, or fixed together by providing a fixing structure on the bottom surface.

[0067] The inlet end of the channel 103 is located at the apex of the cone, the outlet end of the channel 103 is located at the bottom of the cone, and the apex of the cone is connected to the delivery pipeline 12. Therefore, the ejector 10 forms a divergent ejection effect.

[0068] The controller of this embodiment controls the injector 10 to intermittently and impactfully inject the material into the molten metal according to the set injection amount and injection time.

[0069] An inert gas pipeline is provided in the melting equipment 11 and is connected to the inert gas storage device 1 or the inert gas production equipment 2 .

[0070] During operation, the material is added through the material adding device 4 and then closed, the inert gas storage device 1 or the inert gas manufacturing equipment 2 is opened, the inert gas enters the material adding device 4 and carries the material into the conveying pipeline 12, and after being dried by the dryer 5, the flow rate regulating device 6 adjusts the flow rate, and the ultrasonic processor 7 performs ultrasonic pre-dispersion, it enters the elastic energy storage bag 8 for energy storage. When the elastic energy storage bag 8 reaches the set pressure, the controller controls the switch element 9 to open, and the material and gas are injected into the molten metal in the melting device 11 through the injector 10. The molten metal is protected by the inert gas discharged through the inert gas pipeline.
