Description

Technical Field

[0001] The present invention relates to the technical field of non-metallic material preparation in metallurgical engineering, and in particular to a continuous arc purification device and method for artificial graphite. Background Art

[0002] Graphite possesses exceptional properties such as excellent electrical and thermal conductivity, wear resistance, lubricity, and thermal shock resistance. It is also resistant to high temperatures and chemically stable. Consequently, it is increasingly used in industries such as atomic energy, automotive, aerospace, metallurgy, chemical engineering, and machinery, particularly as anode material for lithium-ion batteries. Graphite has become an indispensable non-metallic material in modern industrial technology. The purity of graphite determines its application characteristics and performance; the higher the purity, the greater its application value.

[0003] However, during the cooling process after high-temperature treatment, the existing graphite purification device has a relatively simple internal air flow, which easily forms local air stagnation areas, resulting in uneven cooling, thereby affecting the cooling rate and final quality of the graphite. In addition, coking residues are easily generated on the surface of the material. These residues are easily attached to the inner wall of the cooling box, affecting the cooling effect and the long-term operation of the equipment. For this reason, we propose a continuous arc purification device and method for artificial graphite. Summary of the Invention

By setting a transfer mechanism, the cooling water can be self-circulated in the cooling pipe 14.

[0033] A continuous arc purification method for artificial graphite comprises the following steps:

[0034] S1. The prepared petroleum coke is fed into the furnace body 1 through the screw conveyor 10 and the feed hopper 8. After the two graphite electrodes 9 are energized, the graphitization furnace begins to heat up, and the generated steam and volatile matter are discharged through the dust collection pipe 11;

[0035] S2. After the graphitization of the material is completed, it enters the cooling box 5 at the bottom of the furnace body 1. The servo motor 17 is started to rotate its output shaft clockwise and counterclockwise. By setting a transfer mechanism, the self-circulation of cooling water can be achieved. By setting a rotating lifting mechanism and a stirring mechanism, the stirring rod 37 and the brush block 19 can be moved up and down and rotated and revolved. In this way, the material in the cooling box 5 can be stirred up and down and the attachments adhering to the inner wall of the cooling box 5 can be cleaned. By setting an exhaust mechanism, the air flow can be strengthened, making the air flow in the cooling box 5 more complex and comprehensive, avoiding the problem of uneven cooling caused by local air stagnation;

[0036] S3. Discharge the cooled material through the discharge pipe 4.

[0037] When the present invention is used, the prepared petroleum coke is fed into the furnace body 1 through the screw conveyor 10 and the feed hopper 8. After the two graphite electrodes 9 are energized, the graphitization furnace begins to heat up, and the generated steam and volatile matter are discharged through the dust collecting pipe 11. After the graphitization of the material is completed, it enters the cooling box 5 at the bottom of the furnace body 1. By setting the cooling pipe 14, the material in the cooling box 5 can be cooled. The servo motor 17 is started to rotate its output shaft clockwise and counterclockwise, thereby causing the threaded rod 16 and the rotating block 15 to rotate clockwise and counterclockwise. When the threaded rod 16 rotates clockwise and counterclockwise, the frame 13 and the first The connecting rod 22, the transfer plug 21, the round rod 18, the rotating shaft 36, the flip rod 37 and the brush block 19 move up and down. When the transfer plug 21 moves up and down, a suction effect is generated in the transfer cylinder 20, thereby partially sucking the cooling water in the cooling pipe 14 after absorbing heat into the transfer cylinder 20 through the pumping pipe 12. The cooling water in the transfer cylinder 20 is then squeezed into the refrigeration water tank 7 through the connecting pipe 24 for cooling and cooling. At the same time, the cooling water in the refrigeration water tank 7 after cooling enters the cooling pipe 14 through the water inlet pipe 6, thereby realizing the circulation of cooling water.

[0038] When the round rod 18 moves up and down, because the rotating block 15 is a rectangular block and the rotating block 15 and the rotating groove 28 can always cooperate with each other, the flip rod 37 and the brush block 19 can rotate clockwise and counterclockwise around the axis of the round rod 18. When the round rod 18 moves up and down, the poking rod 26 reciprocates relative to the poking cylinder 32. The poking groove 27 spirally arranged on the poking rod 26 cooperates with the poking block 34, so that the poking cylinder 32 and the second bevel gear 39 can rotate clockwise and counterclockwise. The second bevel gear 39 is meshed with the first bevel gear 38, thereby The flipping rod 37 and the brush block 19 can rotate clockwise or counterclockwise around the axis of the rotating shaft 36, that is, the flipping rod 37 and the brush block 19 can revolve clockwise or counterclockwise around the axis of the round rod 18 while also rotating clockwise or counterclockwise around the axis of the rotating shaft 36, and can also move up and down. In this way, the material can be flipped up and down and the attachments on the inner wall of the cooling box 5 can be cleaned up and down, thereby enhancing the uniformity of material cooling, accelerating the material cooling rate, and effectively removing dust or coke residues generated during the cooling process of the graphitized material, thereby maintaining the cooling efficiency.

[0039] While the rotating block 15 moves up and down, the second connecting rod 35 is provided to enable the exhaust plug 31 to reciprocate in the exhaust cylinder 33, thereby being able to draw the air in the cooling box 5 into the exhaust cylinder 33 through the intake pipe 30, and then discharge it back into the cooling box 5 through the outlet pipe 40. In conjunction with the up and down movement and rotation of the outlet pipe 40, the air flow can be strengthened, making the air flow in the cooling box 5 more complex and comprehensive, avoiding the problem of uneven cooling caused by local air stagnation, helping to dissipate heat more evenly, improving the overall cooling efficiency, and accelerating heat transfer through the flow of air. The flowing air constantly contacts the material and the inner wall of the cooling box 5, taking away heat and enhancing the heat exchange process.

[0040] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
