Description

Technical Field

[0001] The present invention relates to the technical field of graphene preparation, and specifically to a device capable of realizing continuous growth of graphene. Background Technique

[0002] According to existing information, graphene is a high-performance new material with various excellent properties. Currently, the most commonly used method for extracting graphene is the oxidation-reduction method.

[0003] According to the Chinese patent: Authorization Publication No.: CN108928815B, Invention Name: A Method for Preparing High-Performance Graphene by a Multi-Step Weak Oxidation-Reduction Method, which proposes in paragraphs {0043} and {0044} of the specification: "5) Put the collected slurry into an electrothermal blast drying oven, perform drying treatment at 60°C, and then perform ball milling treatment for 3 hours to obtain a graphene powder precursor; 6) Put the graphene powder precursor into a high-temperature atmosphere furnace, and perform high-temperature sintering and thermal reduction at 1000°C under nitrogen protection for 10 hours to obtain high-performance graphene." The graphene powder precursor proposed therein is graphene oxide. In actual graphene preparation, most graphene oxide is directly stored, and when graphene is needed, graphene oxide is heated and reduced to graphene.

[0004] The following problems still exist in the daily use of existing authorized patents, existing equipment of the same technology, and similar equipment of the same type:

[0005] In the actual operation process of the above-mentioned authorized patent, an electrothermal blast drying oven is used for operation to dry the slurry and collect solid graphene oxide. However, the average particle size of graphene is 0.05 - 2.0 μm, and the extraction amount has a huge difference from the raw material ratio. In the process of large-scale extraction, a large amount of slurry needs to be dried to obtain a small amount of graphene oxide. Moreover, the principle of the electrothermal blast drying oven is only to accelerate the evaporation of the liquid by the action of hot air on the liquid surface. Only the liquid surface part is directly affected by the heat. Simply using the electrothermal blast drying oven to evaporate the liquid, the speed is very slow, and the cost invested in extraction has a large gap with the amount of graphene oxide obtained.

[0006] Currently, the evaporators available for large-scale operations separate the solution through multiple groups of perforated plates or metal tubes, increasing the heat transfer area of the solution and improving the evaporation rate. As the solution continuously evaporates, some of the solids or precipitated crystals in the solution will adhere to the perforated plates, making it difficult to collect and process them centrally. Moreover, the amount of graphene oxide obtained in the preparation process is extremely small in itself, and the adhesion and consumption with various components during the evaporation operation further reduce the yield obtained from the preparation. Such as rotary evaporators, freeze dryers, microwave evaporators, ultrasonic evaporators, some of which are experimental equipment and cannot be used for large-scale operations, and some are not convenient for collecting the dried graphene oxide. There is a need for a highly efficient evaporation device specifically applied to the evaporation of graphene oxide. Summary of the Invention

[0010] The evaporation component includes heat pipes, the heat pipes are fixed inside the evaporator main body, the evaporation component assists in dispersing the slurry, increases the surface area of the slurry, and improves the flow rate of hot air by pressurization;

[0011] The auxiliary component includes an air cover, the air cover is fixed at the top end of the evaporator main body, and the auxiliary component dries the humid hot air and heats the slurry in a reciprocating cycle.

[0012] Furthermore, the evaporation component further includes a connecting pipe, the connecting pipe is fixed and communicated with the bottom end of the heat pipe, the left end of the connecting pipe passes through the evaporator main body and extends to the outside of the evaporator main body, partition plates are uniformly and equidistantly fixed inside the heat pipe, and magnet blocks are fixedly connected to the bottom ends of the partition plates.

[0013] Furthermore, pressure blocks are arranged below the partition plates, the pressure blocks are hermetically slidably connected to the inside of the heat pipe, an air inlet hole is vertically penetrated inside the pressure block, and a magnet ball is slidably connected to the inside of the air inlet hole.

[0014] Furthermore, air grooves are evenly formed on the surface of the heat pipe. The positions and numbers of the air grooves respectively correspond to those of the partition plates, and the air grooves communicate between the heat pipe and the evaporator body.

[0015] Furthermore, the evaporation assembly further includes a liquid distribution plate which is fixedly connected to the inner wall of the evaporator body. The positions and numbers of the liquid distribution plates respectively correspond to those of the air grooves, and the bottom ends of the liquid distribution plates are flush with the bottom ends of the air grooves.

[0016] Furthermore, the liquid distribution plate is in a conical shape with a through middle part. Guide grooves are formed on the surface of the inner wall of the liquid distribution plate, liquid accumulation grooves are formed at the bottom ends of the liquid distribution plates, and communicating pipes are fixedly connected and communicated with the outer surfaces of the liquid accumulation grooves.

[0017] Furthermore, an annular liquid collection groove I is formed on the inner wall of the evaporator body. Four liquid collection grooves II are evenly formed at the top ends of the liquid collection groove I. The numbers of the liquid collection grooves II correspond to those of the communicating pipes, and the communicating pipes all extend into the liquid collection grooves II or the liquid collection groove I to communicate with each other.

[0018] Furthermore, the auxiliary assembly further includes a mounting frame which is fixed inside the air cover. Air holes are formed through the surface of the mounting frame.

In cooperation with the evaporation component, it ensures the efficient use of heat energy, further reduces energy consumption, and keeps the temperature in the evaporator main body at a predetermined temperature, increasing the contact degree between the continuously falling slurry and the hot air, and further improving the evaporation effect.

[0024] 4. The solid matter in the slurry is surrounded and centralized by the centralized frame, ensuring that the solid matter will not be carried away by the slurry, reducing the adhesion between the solid matter and the components, and avoiding a large amount of solid matter being adhered, which would lead to a decrease in the amount of graphene oxide obtained by drying. Through the connecting holes, the centrifugal force generated by the rotation of the liquid accumulation bottom cylinder is used to centralize the solid matter, ensuring that the difference between the amount of graphene oxide obtained from each evaporation operation and the predetermined amount is not too large. Compared with traditional evaporation equipment, this device has more advantages and is suitable for chemical preparation operations that require extracting solid matter from solid-liquid mixtures.

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.

[0039] Next, the present invention will be further described in conjunction with the embodiments.

[0040] A graphene device capable of realizing continuous growth in this embodiment, as Figures 1-9 shown, includes an evaporator main body 101. The bottom end of the evaporator main body 101 is connected to a liquid accumulation bottom cylinder 102 through a rotary seal. The bottom end of the liquid accumulation bottom cylinder 102 is fixedly connected and communicated with a conveying pipe 103. A pump body 104 is arranged on the right side of the evaporator main body 101. Conduits 105 are installed at both the upper and lower ends of the pump body 104, and the conduits 105 are respectively fixedly connected and communicated with the upper and lower positions inside the evaporator main body 101;

[0041] An evaporation assembly 200 is arranged inside the evaporator main body 101, and an auxiliary assembly 300 is arranged at the top end of the evaporator main body 101;

[0042] The evaporation assembly 200 includes a heat pipe 201. The heat pipe 201 is fixed inside the evaporator main body 101. The evaporation assembly 200 assists in the dispersion of the slurry, increases the surface area of the slurry, and improves the hot air flow rate by pressurization;

[0043] As a preferred implementation manner in this embodiment, as Figures 1-9As shown, the evaporation assembly 200 further includes a connecting pipe 202. The connecting pipe 202 is fixed and communicated with the bottom end of the heat pipe 201. The left end of the connecting pipe 202 passes through the evaporator main body 101 and extends to the outside of the evaporator main body 101. Partition plates 203 are evenly and equidistantly fixed inside the heat pipe 201. Magnet blocks 204 are fixedly connected to the bottom ends of the partition plates 203;

[0044] Below the partition plates 203, pressure blocks 205 are provided. The pressure blocks 205 are hermetically and slidably connected to the inside of the heat pipe 201. An air inlet hole 206 is vertically penetrated through the inside of the pressure block 205. A magnet ball 207 is slidably connected to the inside of the air inlet hole 206. The inner wall of the top end of the air inlet hole 206 includes iron sheets. The magnet ball 207 adsorbs the iron sheets to seal the top opening of the air inlet hole 206. The side of the magnet ball 207 opposite to the magnet block 204 is the same pole. The diameter of the magnet ball 207 is smaller than the inner diameter of the inner wall of the air inlet hole 206;

[0045] Air grooves 208 are evenly formed on the surface of the heat pipe 201. The positions and numbers of the air grooves 208 correspond to the partition plates 203 respectively. The air grooves 208 connect the heat pipe 201 and the evaporator main body 101, referring to Figure 5 , the air grooves 208 are located at the middle positions between the partition plates 203 and the pressure blocks 205;

[0046] As a preferred implementation manner in this embodiment, as Figures 1-9 shown, the evaporation assembly 200 further includes a liquid distribution plate 209. The liquid distribution plates 209 are fixedly connected to the inner wall of the evaporator main body 101.

[0047] The liquid distribution plate 209 is in a conical shape with a middle penetration. Guide grooves 210 are formed on the inner wall surface of the liquid distribution plate 209. Liquid accumulation grooves 211 are formed at the bottom ends of the liquid distribution plates 209. Communicating pipes 212 are fixedly connected and communicated with the outer surfaces of the liquid accumulation grooves 211. The bottom ends of the guide grooves 210 have openings for the slurry to flow out. The vaporized liquid in the slurry floats up with the hot air, condenses and liquefies after contacting the bottom surface of the liquid distribution plate 209, and is guided by the conical liquid distribution plate 209 and flows into the liquid accumulation grooves 211;

[0048] An annular liquid collection groove one 213 is formed on the inner wall of the evaporator main body 101. Four liquid collection grooves two 214 are evenly formed at the top ends of the liquid collection grooves one 213. The number of the liquid collection grooves two 214 corresponds to the communicating pipes 212. The communicating pipes 212 all extend into the liquid collection grooves two 214 or the liquid collection grooves one 213 and are communicated with each other.

[0049] Compared with the existing authorized patents and the equipment of the same technology, the equipment of the same type and similar technologies achieves the following effects:

[0050] The contact area between the slurry and the hot air is increased, the flow rate of the hot air is increased by pressurization, and the hot air is made to collide with the slurry to improve the evaporation rate, making this device more suitable for large-scale graphene preparation operations.

[0051] On other levels, this embodiment also provides a device for continuously growing graphene, as Figures 1-9 shown. The auxiliary component 300 includes an air cover 301, and the air cover 301 is fixed to the top of the evaporator main body 101. The auxiliary component 300 dries the humid hot air and reciprocally circulates to heat the slurry.

[0052] As a preferred implementation manner in this embodiment, as Figures 1-9 shown, the auxiliary component 300 further includes a mounting frame 302. The mounting frame 302 is fixed inside the air cover 301. Through holes 303 are all formed through the surface of the mounting frame 302. A trachea 304 is arranged on the right side of the evaporator main body 101. The top end of the trachea 304 is fixed and communicated with the air cover 301, and the bottom end of the air cover 301 is fixed and communicated with the lower part of the evaporator main body 101. An object for absorbing moisture in the gas, such as a superabsorbent resin, lime, etc., is loaded into the through holes 303, and it is ensured that the through holes 303 are not blocked.

[0053] As a preferred implementation manner in this embodiment, as Figures 1-9 shown, a concentrated frame 305 is fixedly connected to the bottom end of the liquid accumulation bottom cylinder 102. The concentrated frame 305 covers the upper end opening of the delivery pipe 103 therein. Communication holes 306 are evenly formed on the surface of the concentrated frame 305. The communication holes 306 are conical. The aperture of the communication holes 306 facing the outside of the concentrated frame 305 is larger than the aperture of the communication holes 306 facing the inside of the concentrated frame 305.

[0054] Compared with the existing authorized patents and the equipment of the same technology and similar equipment of the same type, the following effects are achieved:

[0055] With the assistance of the centrifugal force generated by the rotation of the liquid accumulation bottom cylinder 102 through the communication holes 306, the solid substances are concentrated, ensuring that the difference between the obtained graphene oxide and the predetermined amount in each evaporation operation will not be too large. Compared with traditional evaporation equipment, this device has more advantages and is suitable for chemical preparation operations that require extracting solid substances from solid-liquid mixtures.

[0056] The above complete working principle and working process are as follows:

[0057] Please refer to Figures 1-9 , it is known that in the process of graphene preparation, the solid-liquid mixed slurry generated, hereinafter referred to as slurry, has a solid content of only about 10%; the liquid accumulation bottom cylinder 102 is linked with the motor through a belt drive system, and the rotation of the liquid accumulation bottom cylinder 102 can be controlled by the motor.

[0058] In use, the user first connects the delivery pipe 103 to an external conduit through a rotary seal, and conveys the slurry to the inside of the liquid accumulation bottom cylinder 102 through the conduit for accumulation. The liquid level of the conveyed slurry needs to be below the heat pipe 201. After the slurry is conveyed, the delivery pipe 103 is closed, and then the external motor is started. The motor drives the liquid accumulation bottom cylinder 102 to rotate through a belt drive system. The liquid accumulation bottom cylinder 102 drives the slurry inside to rotate and generate centrifugal force, causing the solids in the slurry to gather towards the middle of the inner bottom end of the liquid accumulation bottom cylinder 102 due to the centrifugal force, while the liquid moves towards the surroundings under the force, resulting in the liquid level around the slurry rising. At this time, the pump body 104 is started, and the slurry is conveyed from the liquid accumulation bottom cylinder 102 to the upper part inside the evaporator main body 101 through the conduit 105. Due to the centrifugal force, the solid matter is concentrated in the middle, thereby minimizing the solids in the slurry being sucked into the pump body 104 as much as possible. The slurry first falls on the uppermost liquid distribution plate 209. Since the inner wall of the liquid distribution plate 209 is provided with spiral guide grooves 210, the slurry flows in the guide grooves 210, and the guide grooves 210 are spiral, which increases the residence time of the slurry inside the liquid distribution plate 209 and increases the surface area of the slurry in contact with the space through the guide grooves 210;

[0059] At this time, the user connects the connecting pipe 202 to an external heat source, and conveys hot air into the inside of the heat pipe 201 through the connecting pipe 202. It is known that the pressing block 205 is slidably and sealedly connected to the inside of the heat pipe 201, and the inner wall of the top end of the air inlet hole 206 includes iron sheets. The magnet ball 207 adsorbs the iron sheets to seal the top opening of the air inlet hole 206. The diameter of the magnet ball 207 is smaller than the inner diameter of the air inlet hole 206. The side of the magnet ball 207 opposite to the magnet block 204 is of the same pole. At this time, the pressing block 205 and the magnet ball 207 seal the space at the bottom end of the heat pipe 201. As hot air continuously enters from the bottom end of the heat pipe 201, the air pressure in the space at the bottom end of the heat pipe 201 continuously increases. The air pressure pushes the pressing block 205 and the magnet ball 207 inside it to move upward. As the magnet ball 207 continuously moves upward closer to the magnet block 204, the repulsive force between the two increases. By the magnetic force against the air pressure, the air pressure at the bottom end of the heat pipe 201 continuously increases. As the air pressure continuously increases, it pushes the pressing block 205 to move upward continuously. When the pressing block 205 moves upward to the air groove 208, the hot air pours outwards at high speed through the air groove 208. And because the position of the air groove 208 corresponds to the liquid distribution plate 209, the hot air directly impacts on the surface of the slurry in the guide grooves 210, causing the slurry to start to evaporate. And the general direction of the slurry in the guide grooves 210 is downward flow, while the hot air is guided by the inclined surface of the inner wall of the liquid distribution plate 209 to move obliquely upward, causing the hot air and the slurry to collide, accelerating evaporation. And affected by the air pressure and the size of the air groove 208, the hot air is ejected at high speed, further increasing the evaporation speed by accelerating the air flow;

[0060] Reference Figures 4-6, during the process that hot air inclines outward from the inside of the heat pipe 201 through the air groove 208, since the pressing block 205 is continuously pushed upward by air pressure, the magnet ball 207 moves downward under the magnetic repulsion of the magnet block 204, resulting in the magnet ball 207 no longer sealing the air inlet hole 206. At this time, part of the hot air inside the heat pipe 201 moves upward through the air inlet hole 206 and continues to move upward inside the heat pipe 201 via the partition plate 203, causing all the components above to repeat the above movement process;

[0061] It can be concluded that the above movement process separates the solid and liquid of the slurry through centrifugal force, restricts the movement of solid substances, avoids the continuous contact of solid substances with other components, causing consumption and reducing the yield of graphene oxide; divides the slurry into multiple flows, greatly increases the contact area between the slurry and hot air, increases the flow rate of hot air by pressurization, and makes the hot air collide with the slurry to improve the evaporation rate;

[0062] As the slurry continuously evaporates, the hot air in the evaporator main body 101 moves upward with water vapor and contacts the bottom surface of the liquid distribution plate 209. The relatively high-temperature water vapor contacts the relatively low-temperature liquid distribution plate 209, and a liquefaction reaction occurs, generating condensed water at the bottom of the liquid distribution plate 209. Guided by the conical bottom surface of the liquid distribution plate 209, the condensed water flows into the liquid accumulation tank 211 and enters the second liquid collection tank 214 and the first liquid collection tank 213 through the connecting pipe 212 and is discharged for centralized treatment, avoiding the condensed liquid from falling back into the slurry again, resulting in ineffective evaporation operations;

[0063] The hot air continuously moves upward with water vapor in the heat pipe 201 and the evaporator main body 101 and enters the inside of the installation frame 302 through the air permeable holes 303. It is known that highly absorbent resin or lime is added to the air permeable holes 303. When the hot air moves upward with water vapor through the air permeable holes 303, the water is absorbed, making the hot air discharged into the air cap 301 return to a dry state, and the hot air is input again to the lower part inside the evaporator main body 101 through the air pipe 304, thereby recycling the hot air for evaporation operations;

[0064] Reference Figure 9, it is known that the centralized frame 305 covers the upper end opening of the conveying pipe 103. The surface of the centralized frame 305 is evenly provided with communication holes 306. The communication holes 306 are conical. The aperture of the communication hole 306 facing the outside of the centralized frame 305 is larger than the aperture of the communication hole 306 facing the inside of the centralized frame 305. The slurry discharged from the conveying pipe 103 into the internal liquid accumulation bottom cylinder 102 surrounds the solid matter in the slurry through the centralized frame 305, and the communication holes 306 prevent the liquid from carrying the solid matter out of the centralized frame 305. When the liquid accumulation bottom cylinder 102 drives the slurry to rotate, the solid matter moves into the centralized frame 305 through the communication holes 306 with a large aperture facing the outside of the centralized frame 305. The communication holes 306 limit the overflow of the solid matter inside the centralized frame 305 through the openings with a small aperture on the inner side, ensuring that the solid matter is concentrated inside the centralized frame 305 to the greatest extent, thereby avoiding the large consumption of graphene oxide after drying and affecting the harvest. The user can continuously input the slurry into the liquid accumulation bottom cylinder 102 through the conveying pipe 103 and continuously carry out the evaporation operation to ensure the continuity of the graphene extraction work.
