DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] Please refer to Figures 1-7 An embodiment of the present application is: a heating and purification device for graphene slurry, an auxiliary device for keeping the feeding of graphene powder unobstructed, comprising an auxiliary device, and the auxiliary device further comprises;

[0033] The box 1 is used as a processing carrier for graphene powder, and a motor is vertically arranged on the top of the box 1.

[0034] The feed pipe 2 is fixedly installed on the top of the box 1, and is used as a feeding inlet for graphene powder.

[0035] The heater 3 is fixedly installed on the right side of the box 1, and is used for heating the graphene powder.

[0036] The rotating rod 401 is fixedly installed at one end of the output end of the motor, and the right-angle rod 402 is fixedly installed on the circumferential surface of the other end of the rotating rod 401. The right-angle rod 402 is used for stirring the graphene powder to avoid blockage. The L-shaped rod 403 is fixedly installed at the bottom of the right-angle rod 402, and is used for removing the possible "bridge" phenomenon, ensuring uniform heating of the graphene powder, and ensuring that all powder particles can uniformly absorb heat, avoiding local overheating or substandard heating caused by uneven heating, and significantly improving the stability of the heating process and the quality of the final product.

[0037] The auxiliary device further comprises a thin rod 404, a cuboid 405, a round rod 406 and a vibrating plate 407, one end of the thin rod 404 is fixedly installed at the other end of the rotating rod 401, the cuboid 405 is fixedly installed at the other end of the thin rod 404, the round rod 406 is fixedly installed at the bottom of the cuboid 405, and the vibrating plate 407 is fixedly installed on the inner wall of the feeding pipe 2. When the L-shaped rod 403 rotates, it will contact the vibrating plate 407, and when the L-shaped rod 403 contacts the vibrating plate 407, the vibrating plate 407 will vibrate. Due to the characteristics of graphene powder, the "bridge" phenomenon may occur during the transportation of graphene powder.

[0038] The circumference of the thin rod 404 is provided with a reciprocating spiral groove, and the L-shaped rod 403 contacts the vibrating plate 407. When the vibrating plate 407 vibrates, the "bridge" phenomenon of the graphene powder above the right-angle rod 402 is destroyed, so that the graphene powder can be transported smoothly and uniformly. When the rotating rod 401 rotates, the thin rod 404 rotates.

[0039] When the device works: start the heater 3 to heat the inside of the box 1, pour the graphene powder into the inside of the feeding pipe 2, and when the inside of the feeding pipe 2 is full of graphene powder, the inside of the feeding pipe 2 may be blocked due to the characteristics of graphene powder. Start the motor, which will drive the rotating rod 401 to rotate, and when the rotating rod 401 rotates, the right-angle rod 402 will rotate, which will dredge the graphene powder at the bottom of the inside of the feeding pipe 2. When the right-angle rod 402 rotates, the L-shaped rod 403 rotates, and when the L-shaped rod 403 rotates, it contacts the vibrating plate 407, which vibrates. Due to the characteristics of graphene powder, the "bridge" phenomenon may occur during the transportation of graphene powder. At this time, when the vibrating plate 407 vibrates, the "bridge" phenomenon of the graphene powder above the right-angle rod 402 is destroyed, so that the graphene powder can be transported smoothly and uniformly. When the graphene powder completely enters the top of the bottom plate 508, pour the acid liquid into the inside of the box 1, mix the graphene powder with the acid liquid to form graphene slurry, and when the rotating rod 401 rotates, the thin rod 404 rotates, which drives the cuboid 405 to rotate, and when the cuboid 405 rotates, the round rod 406 rotates, which stirs the graphene powder in the inside of the box 1, ensuring that the graphene powder is uniformly heated.

[0040] Please refer to Figures 1-7On the basis of the above-mentioned embodiments, in another embodiment of the present application, wherein the inside of the box 1 is provided with a gathering device for gathering the graphene powder scattered around and a shaking device for avoiding agglomeration and sticking to the bottom when recycling after heating is completed, the gathering device comprises a cross rod 501, a square box 502, a column rod 503 and a square rod 504, one end of the cross rod 501 is slidingly installed on the reciprocating spiral groove, the square box 502 is fixedly installed at the end of the cross rod 501 away from the thin rod 404, one end of the column rod 503 is fixedly installed at the bottom of the square box 502, the square rod 504 is fixedly installed at the other end of the column rod 503, effectively overcoming the adsorption force of the powder on the surface of the flap 505, allowing the agglomerated graphene powder to separate from the flap 505 and fall to the top of the cover plate 606, ensuring that the powder that may have been left is fully recycled, reducing material loss in detail and improving material utilization rate in the overall production process.

[0041] The gathering device further comprises a flap 505, a round block 506, an inclined block 507 and a bottom plate 508, the bottom plate 508 is fixedly installed on the inner wall of the box 1, the flap 505 is rotatably installed on the top of the bottom plate 508, the round block 506 is fixedly installed on the inner wall of the box 1, the inclined block 507 is fixedly installed on the top of the bottom plate 508, when the flap 505 is turned over, the graphene powder on the flap 505 will be poured into the top of the cover plate 606, when the graphene powder is on the cover plate 606, the round rod 406 will stir the graphene powder, and when the square box 502 moves, it will contact the round block 506.

[0042] The square rod 504 contacts the flap 505, the square box 502 contacts the round block 506, and the flap 505 contacts the inclined block 507, when the square box 502 vibrates, the square rod 504 will vibrate, when the square rod 504 vibrates, the flap 505 will shake, and when the flap 505 shakes, the graphene powder agglomerated on the flap 505 will fall to the top of the cover plate 606.

[0043] The shaking device comprises an elastic telescopic rod 601, a contact rod 602, a blocking rod 603, a tipping plate 604, a cylinder 605, a cover plate 606, a pull rod 607 and a bottom sliding plate 608. The bottom sliding plate 608 is slidingly installed at the bottom of the box body 1. The fixed end of the elastic telescopic rod 601 is fixedly installed at the bottom of the column rod 503. The tipping plate 604 is fixedly installed at the free end of the elastic telescopic rod 601. The contact rod 602 is fixedly installed at the free end of the elastic telescopic rod 601. The blocking rod 603 is fixedly installed at the inner wall of the box body 1. The cover plate 606 is rotatably installed at the inside of the bottom plate 508. The pull rod 607 is slidingly installed at the bottom of the bottom plate 508. The cylinder 605 is fixedly installed at the top of the tipping plate 604. The internal structure of the box body 1 is a metal structure. The heating temperature inside the box body 1 is above the melting point of impurities such as carbon, iron and silicon. The temperature that the metal structure inside the box body 1 can withstand is much greater than the heating temperature inside the box body 1, so that the structure inside the box body 1 is not affected by the temperature change inside the box body 1, preventing sudden temperature drop. The graphite powder may be affected by thermal expansion and contraction, resulting in a decrease in structural stability or performance. The heat preservation measure ensures that the heating effect of the powder is maintained from the perspective of environmental temperature control, reducing the quality loss caused by temperature drop.

[0044] The contact rod 602 is in contact with the blocking rod 603. The cover plate 606 is in contact with the pull rod 607. A clock spring is arranged between the cover plate 606 and the bottom plate 508. When the graphite powder falls onto the cylinder 605, it will first scatter around. When the elastic telescopic rod 601 moves upward, the tipping plate 604 will be driven to move upward.

[0045] When the thin rod 404 rotates, the cross rod 501 moves up and down on the circumference of the thin rod 404. When the cross rod 501 moves, the square frame 502 moves. When the square frame 502 moves, the column rod 503 moves. When the column rod 503 moves, the square rod 504 moves. When the square rod 504 moves, the flap 505 flips. When the flap 505 flips, it moves along the inclined block 507. When the flap 505 flips, the graphite powder on the flap 505 falls onto the top of the cover plate 606. When the graphite powder is on the cover plate 606, the round rod 406 stirs the graphite powder. When the square frame 502 moves, it contacts the round block 506. When the square frame 502 contacts the round block 506, the square frame 502 vibrates. When the square frame 502 vibrates, the square rod 504 vibrates. When the square rod 504 vibrates, the flap 505 shakes. When the flap 505 shakes, the graphite powder adhered to the flap 505 falls onto the top of the cover plate 606, avoiding waste caused by adhesion of the graphite powder.

[0046] When the column 503 is moving, the elastic telescopic rod 601 is also moving, the staff pulls the pull rod 607 outward, when the pull rod 607 moves outward, the cover plate 606 is released, when the cover plate 606 is released, the graphene powder accumulated on the cover plate 606 falls to the top of the bottom slide plate 608, when the cover plate 606 is opened, the heat above the bottom plate 508 enters between the bottom slide plate 608 and the bottom plate 508, which can effectively keep the heat and avoid the damage caused by the rapid cooling of the graphene powder just after heating, at the same time, when the graphene powder on the cover plate 606 falls onto the top plate 604, it will first fall onto the cylinder 605, when the graphene powder falls onto the cylinder 605, it will first scatter around, when the elastic telescopic rod 601 moves upward, it will first drive the top plate 604 to move upward, at the same time, when the elastic telescopic rod 601 moves, it will drive the contact rod 602 to move, when the contact rod 602 moves, it will contact the stop rod 603, when the elastic telescopic rod 601 continues to move, it will drive the contact rod 602 to bend so that the contact rod 602 moves above the stop rod 603, when the contact rod 602 moves above the stop rod 603, the limit of the elastic telescopic rod 601 is released, when the limit of the elastic telescopic rod 601 is released, the elastic telescopic rod 601 will quickly move upward, when the elastic telescopic rod 601 moves upward quickly, it will drive the top plate 604 to move quickly, when the top plate 604 moves upward quickly, the graphene powder on the top plate 604 will jump, when the elastic telescopic rod 601 moves upward, the contact rod 602 will contact the stop rod 603, at this time, the elastic telescopic rod 601 will be compressed, when the elastic telescopic rod 601 is compressed to the extreme, the contact rod 602 will bend to the bottom of the stop rod 603, at this time, the elastic telescopic rod 601 will quickly rebound downward, when the elastic telescopic rod 601 moves downward quickly, it will drive the top plate 604 to move downward quickly, when the top plate 604 moves, the graphene powder on the top plate 604 will jump, which avoids the graphene powder from sticking to the top plate 604 just after heating, when the temperature inside decreases and the acid liquid in the graphene slurry evaporates, the bottom slide plate 608 is extracted to take out the graphene powder inside.
