Description

Technical Field

[0001] The present invention relates to the technical field of wire compounding machines, and more particularly to a graphene production device. Background Art

[0002] Graphene is a single-atom-thick layer of carbon atoms, a single-layer two-dimensional crystal in which carbon atoms are arranged in a honeycomb lattice of a hexagonal plane with a thickness of only a single layer of atoms formed by sp2 hybridized carbon atoms. Graphene is the thinnest known material and is also very strong and hard; as a simple substance, it conducts electrons faster at room temperature than all known conductors and semiconductors. At the same time, as a single-layer carbon atom structure, the theoretical specific surface area of graphene is as high as 3000 m2 / g. Such a high specific surface area makes graphene-based materials extremely promising active materials for energy storage and have good application prospects in aspects such as hydrogen storage, new lithium-ion batteries, supercapacitors, or fuel cells.

[0003] Currently, methods for preparing graphene include the oxidation-reduction method. The oxidation-reduction method usually oxidizes graphite into graphene oxide and then obtains graphene through chemical reduction or thermal reduction; during the oxidation-reduction process, graphene oxide needs to be dispersed in a solution (such as water or an organic solvent), and stirring can ensure uniform reaction, causing the solution to react to form a solution containing graphene. Finally, the solution is taken out for filtration and drying to obtain graphene. However, in today's preparation devices, when stirring the mixed solution, the stirring method is single, and some viscous particles containing graphene are likely to adhere to the inner wall of the device and cannot react completely. Moreover, the bottom-up heating method easily causes the solution at the bottom of the device to be heated faster than the solution at the top of the device, thus affecting the reaction rate of the solution. Summary of the Invention

[0004] The purpose of the present invention is to address the problems that existing graphene production devices cannot stir the mixed solution in multiple directions, remove some viscous particles adhering to the inner wall of the device, and the uneven heating of the solution affects the reaction rate.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0034] As Figures 1 to 3 shown, this embodiment provides a graphene production device, including a base 1 and a preparation cylinder 2 rotatably arranged on the top of the base 1. A mixing mechanism is provided on the top of the base 1. The mixing mechanism includes a lifting component 3 arranged on the top of the base 1, a driving component 4 arranged on the lifting component 3, a stirring component 5 arranged at the output end of the driving component 4 and whose disturbance radius can expand relative to the axis of the preparation cylinder 2, and a bouncing component 6 arranged on the lifting component 3 and capable of driving the stirring component 5 to move vertically back and forth relative to the preparation cylinder 2 when the stirring component 5 is working. A rotating mechanism is also provided on the top of the base 1. The rotating mechanism includes a rotating component 7 arranged on the top of the base 1 for driving the preparation cylinder 2 to rotate back and forth, and a pushing component 8 arranged on the lifting component 3 and capable of driving the rotating component 7 to rotate while the stirring component 5 is working. A heating mechanism 10 capable of evenly spraying hot air from the bottom up into the mixed solution through the preparation cylinder 2 is provided inside the preparation cylinder 2;

[0035] When preparing graphene by the redox method, graphite is first oxidized to graphene oxide, and then graphene oxide and a reducing agent are put into the reaction chamber inside the preparation cylinder 2 through the feed inlet at the top of the preparation cylinder 2. It should be noted that water or an organic solvent can be used as the reducing agent. After the graphene oxide and the reducing agent are mixed and reacted, a solution containing graphene can be generated. At this time, the lifting member 3 can be set to drive the stirring member 5 to move downward and extend into the preparation cylinder 2. The stirring member 5 can be expanded to contact the inner side of the preparation cylinder 2. Then, the driving member 4 drives the stirring member 5 to work to stir the mixed solution. At the same time, the driving member 4 can also drive the stirring member 5 to reciprocate up and down relative to the preparation cylinder 2 through the elastic member 6. Therefore, when the stirring member 5 rotates inside the preparation cylinder 2, it can also move up and down, disturbing the mixed solution from multiple directions. This can not only clean the inner wall of the preparation cylinder 2 with different diameters, preventing some viscous particulate matters from adhering to the inner wall of the preparation cylinder 2 and being incompletely reacted, but also improve the reaction rate of the mixed solution. Moreover, through the heating mechanism 10 provided, hot air can be evenly sprayed into the solution in the preparation cylinder 2 from the bottom up. This can not only blow up the precipitated particulate matters to make the reaction complete, but also cooperate with the stirring member 5 to stir the hot air to various positions inside the preparation cylinder 2, facilitating the uniform heating of the solution in the preparation cylinder 2 and further improving the reaction rate. Finally, when the solution reacts into a solution containing graphene, the pump body provided on the base 1 can work to pump out the solution inside the preparation cylinder 2, and then filter out the graphene in the solution and dry it to prepare graphene.

[0036] As Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 11 shown, as a preferred embodiment, on the basis of the above method, further, the lifting member 3 includes cylinders 301 arranged on both sides of the top of the base 1, piston columns 302 arranged at the output ends of the cylinders 301, a support frame 303 arranged at the tops of the two piston columns 302, a bracket 304 slidably arranged inside the support frame 303, and a first spring 305 arranged between the bottom of the bracket 304 and the inner bottom wall of the support frame 303;

[0037] The driving member 4 includes a motor 401 arranged on the side wall of the bracket 304, a driving bevel gear 402 arranged on the output shaft of the motor 401, a rotating column 403 rotatably arranged on the side wall of the bracket 304, and a driven bevel gear 404 arranged at the top of the rotating column 403;

[0038] The stirring component 5 includes a mounting cylinder 501 arranged at the bottom of the rotating column 403, two mounting seats 502 sleeved outside the mounting cylinder 501, a number of first pressing shafts 503 movably arranged on the side wall of the mounting seat 502, a disturbing plate 504 movably arranged on the side of the first pressing shaft 503 away from the mounting seat 502, a scraping blade 5041 arranged on the side wall of the disturbing plate 504, an electric push rod 505 arranged at the bottom of the mounting cylinder 501, and a number of second pressing shafts 506 movably arranged between the bottom of the electric push rod 505 and a number of disturbing plates 504;

[0039] The bouncing component 6 includes a rotating rod 601 rotatably arranged on the inner side wall of the bracket 304, a cam 602 arranged on the rod wall of the rotating rod 601, a connecting plate 603 fixedly arranged on the side wall of the support frame 303, a pulley 604 arranged on the top of the connecting plate 603 and in contact with the cam 602, a rotating shaft 606 arranged on the end face of the driving bevel gear 402, and a belt pulley 605 drivingly arranged between the rotating shaft 606 and the rotating rod 601;

[0040] After the graphene oxide and the reducing agent are placed inside the preparation cylinder 2, the cylinder 301 is started to work. The piston rod 302 drives the support frame 303 to move downward, so that the mounting cylinder 501 and the disturbance plate 504 on the support 304 extend into the preparation cylinder 2. The feeding port of the preparation cylinder 2 can be blocked by the cylinder cover arranged outside the rotating column 403. Then, the electric push rod 505 is started to stretch and drive a plurality of second pressing shafts 506 to move. Cooperating with a plurality of first pressing shafts 503, the disturbance plate 504 can be unfolded to contact the inner wall of the preparation cylinder 2. Then, the motor 401 is started to work to drive the driving bevel gear 402 to rotate. The driving bevel gear 402 will drive the rotating column 403 provided with the driven bevel gear 404 to rotate. The rotating column 403 will drive the mounting cylinder 501 and a plurality of disturbance plates 504 to rotate to stir the mixed solution. At the same time, the scraping blades 5041 on the side wall of the disturbance plate 504 can scrape off the viscous particulate matters adhering to the inner wall of the preparation cylinder 2 for continuous reaction, facilitating the complete reaction of the solution. Moreover, the driving bevel gear 402 will also drive the rotating rod 601 to rotate through the rotating shaft 606 and the pulley 605. The rotating rod 601 will drive the cam 602 to rotate. When the small head part of the cam 602 contacts the pulley 604, the support 304 will be lifted and the first spring 305 will be stretched. When the large head part of the cam 602 contacts the pulley 604, the first spring 305 will drive the support 304 to move downward to reset. Therefore, while the disturbance plate 504 rotates relative to the preparation cylinder 2, it can also reciprocate up and down, facilitating the agitation of the solution inside the preparation cylinder 2 from multiple directions, increasing the collision strength between the solutions, and thus being able to improve the reaction speed of the solution. Finally, when the solution reaction ends to generate graphene, the electric push rod 505 is driven to drive the disturbance plate 504 to contract and reset. Then, the cylinder 301 is driven to drive the support frame 303 and the support 304 to move upward, so that the mounting cylinder 501 and the disturbance plate 504 are separated from the preparation cylinder 2.

[0041] As Figure 3 , Figure 7 and Figure 8 shown, as a preferred embodiment, on the basis of the above method, further, the rotating member 7 includes a first support column 101 and a second support column 102 rotatably arranged on the top of the base 1, a first gear 701 sleeved on the rod wall of the first support column 101, a second gear 702 sleeved on the rod wall of the second support column 102, and a tooth ring 703 arranged on the outer wall of the preparation cylinder 2;

[0042] The pushing member 8 includes a sliding frame 801 arranged on the side wall of the support frame 303, a toothed plate 802 slid on the inner wall of the sliding frame 801, a push-pull column 803 movably arranged between the toothed plate 802 and the support 304, a worm 804 rotatably arranged at the bottom of the sliding frame 801, a third gear 805 sleeved on the end of the worm 804, and a worm gear 806 arranged on the top of the first support column 101;

[0043] When the support 304 bounces up and down, it can also push and pull the column 803 to squeeze the toothed plate 802 back and forth, causing the toothed plate 802 to slide reciprocally in the sliding frame 801. The toothed plate 802 will drive the worm 804 provided with the third gear 805 to rotate reciprocally. The worm 804 will drive the first support column 101 provided with the worm gear 806 to rotate reciprocally. The first support column 101 will then drive the second gear 702 to rotate through the first gear 701, and finally drive the preparation cylinder 2 provided with the toothed ring 703 to rotate reciprocally. Therefore, the preparation cylinder 2 can rotate reciprocally relative to the disturbance plate 504, causing the solution to generate convection, further increasing the collision force between the solutions, thereby increasing the mixing reaction speed of the solutions. Additionally, in order to prevent foreign objects from touching the toothed ring 703, the first gear 701, and the second gear 702 and affecting the rotation of the preparation cylinder 2, an anti-slip cover can also be provided between the outside of the preparation cylinder 2 and the first support column 101 and the second support column 102 to shield and protect the components of the rotating part 7 and avoid affecting the operation of the rotating part 7.

[0044] As Figure 8 shown, as a preferred embodiment, on the basis of the above method, further, a collision assembly 9 is also provided on the sliding frame 801. The collision assembly 9 includes a top column 901 provided at the end of the toothed plate 802 and extending outward through the sliding frame 801 and the support frame 303, an arc-shaped plate 902 provided at the end of the top column 901, and a plurality of rolling balls 903 rotatably provided on the inner side wall of the arc-shaped plate 902;

[0045] When the toothed plate 802 reciprocates, it can also drive the top column 901 to slide reciprocally. The top column 901 will drive the arc-shaped plate 902 to move back and forth and impact the preparation cylinder 2. The rolling balls 903 rotatably provided on the inner side of the arc-shaped plate 902 will roll when contacting the preparation cylinder 2, preventing jamming when the rotating preparation cylinder 2 contacts the arc-shaped plate 902. Therefore, the preparation cylinder 2 can be vibrated to shake off the viscous particulate matter adhering to the inner wall of the preparation cylinder 2, facilitating further complete reaction of the solution.

[0046] As Figure 4 , Figure 5 and Figure 9 shown, as a preferred embodiment, on the basis of the above method, further, a partition plate 201 is provided on the inner side wall of the preparation cylinder 2. The partition plate 201 divides the preparation cylinder 2 into a reaction chamber and a flow chamber. The heating mechanism 10 includes a hot air blower 1001 provided on the top of the base 1 and with its output end communicating with the flow chamber, a plurality of air inlet pipes 1002 provided on the top of the partition plate 201 and communicating with the flow chamber, and a U-shaped exhaust pipe 1003 provided on the top of the air inlet pipe 1002. The exhaust port of the U-shaped exhaust pipe 1003 faces vertically downward relative to the partition plate 201;

[0047] The heating mechanism 10 further includes a fixing ring 1004 fixedly arranged on the inner wall of the vertical section of the U-shaped exhaust pipe 1003, a sealing head 1006 slidably arranged on the inner wall of the vertical section of the U-shaped exhaust pipe 1003, and a second spring 1005 arranged between the sealing head 1006 and the fixing ring 1004;

[0048] While disturbing the solution, the hot air blower 1001 can be started to work. The hot air is first introduced into the flow cavity inside the preparation cylinder 2 and then enters the U-shaped exhaust pipe 1003 through the air inlet pipe 1002. The sealing head 1006 in the U-shaped exhaust pipe 1003 is squeezed by the gas and will slide downward to disengage from the exhaust port of the U-shaped exhaust pipe 1003. At this time, the hot air will be sprayed downward into the solution to heat the solution to improve the reaction speed of the solution, while the solution cannot flow back into the inside of the U-shaped exhaust pipe 1003. Therefore, through multiple U-shaped exhaust pipes 1003, the hot air can be evenly introduced into various positions inside the preparation cylinder 2. It can not only blow up the precipitated particulate matter for continuous reaction, but also cooperate with the stirring plate 504 to stir the hot air to various positions inside the preparation cylinder 2, facilitating the uniform heating of the solution at different positions and improving the reaction speed of the solution. After the solution mixing is completed, when the hot air blower 1001 is turned off, after the wind pressure on the sealing head 1006 stops, the second spring 1005 is released from the force and will drive the sealing head 1006 to move upward and reset to block the exhaust port of the U-shaped exhaust pipe 1003 again.

[0049] Working principle of the present invention: First, graphene oxide and a reducing agent are put into the preparation cylinder 2. The air cylinder 301 is started to work, driving the mounting cylinder 501 and the disturbance plate 504 on the bracket 304 to extend into the interior of the preparation cylinder 2. Then, the electric push rod 505 is started to stretch and drive a plurality of second pressing shafts 506 to move. Cooperating with a plurality of first pressing shafts 503, the disturbance plate 504 can be unfolded to contact the inner wall of the preparation cylinder 2. Then, the motor 401 is started to work to drive the driving bevel gear 402 to rotate. The driving bevel gear 402 will drive the rotating column 403 provided with the driven bevel gear 404 to rotate. The rotating column 403 will drive the mounting cylinder 501 and a plurality of disturbance plates 504 to rotate to stir the mixed solution. At the same time, the scraping blades 5041 on the side wall of the disturbance plate 504 can scrape off the viscous particulate matter adhering to the inner wall of the preparation cylinder 2 for continuous reaction, facilitating the complete reaction of the solution. Moreover, the driving bevel gear 402 will also drive the rotating rod 601 to rotate through the rotating shaft 606 and the pulley 605. The rotating rod 601 will drive the cam 602 to rotate. The cam 602 drives the bracket 304 to move downward and reset. Therefore, while the disturbance plate 504 rotates relative to the preparation cylinder 2, it can also reciprocate up and down, facilitating the agitation of the solution inside the preparation cylinder 2 from multiple directions and increasing the collision force between the solutions, thereby improving the reaction speed of the solution. And when the bracket 304 reciprocates up and down, it can also squeeze the toothed plate 802 back and forth through the push-pull column 803, causing the toothed plate 802 to reciprocate in the sliding frame 801. The toothed plate 802 will drive the worm 804 provided with the third gear 805 to rotate reciprocally. The worm 804 will drive the first support column 101 provided with the worm gear 806 to rotate reciprocally. The first support column 101 then drives the second gear 702 to rotate through the first gear 701, and finally drives the preparation cylinder 2 provided with the toothed ring 703 to rotate reciprocally. Therefore, the preparation cylinder 2 can rotate reciprocally relative to the disturbance plate 504, causing the solution to generate convection, further increasing the collision force between the solutions, and thus improving the mixing and reaction speed of the solution. At the same time, the hot air blower 1001 can be started to work. The hot air is first introduced into the flow chamber inside the preparation cylinder 2, and then enters the U-shaped exhaust pipe 1003 through the air inlet pipe 1002. The sealing head 1006 in the U-shaped exhaust pipe 1003 is squeezed by the gas and will slide downward to disengage from the exhaust port of the U-shaped exhaust pipe 1003. At this time, the hot air will be sprayed downward into the solution to heat the solution to improve the solution reaction speed, and the solution cannot flow back into the interior of the U-shaped exhaust pipe 1003. Therefore, through a plurality of U-shaped exhaust pipes 1003, the hot air can be evenly introduced into various positions inside the preparation cylinder 2. It can not only blow up the precipitated particulate matter for continuous reaction, but also cooperate with the disturbance plate 504 to stir the hot air to various positions inside the preparation cylinder 2, facilitating the uniform heating of the solution at different positions and improving the solution reaction speed. Finally, when the solution reacts to form a solution containing graphene, the pump body provided on the base 1 can be started to pump out the solution inside the preparation cylinder 2, and then the graphene in the solution is filtered out and dried to prepare graphene.
