Description

Technical Field

[0001] The invention relates to the technical field of graphite chemical packaging and furnace discharging devices, in particular to graphite chemical packaging and furnace discharging equipment for negative electrode materials. Background Art

[0002] Graphite has become the most widely used negative electrode material in lithium-ion batteries due to its good conductivity, layered structure suitable for lithium embedding and de-embedding, and good cycle performance. However, carbon materials that have not been graphitized cannot fully exert their advantages as negative electrode materials. High-temperature graphitization treatment is required to rearrange the carbon atoms to form a hexagonal network layer stacking structure and transform them into graphite materials with excellent performance. Therefore, special graphitization furnace equipment is needed to realize this process in order to meet the performance requirements of negative electrode materials.

[0003] In the prior art, the mechanisms for the operation of clinker and raw material need to be set up separately, that is, the operation of clinker requires a separate set of mechanisms, and the operation of raw material also requires a separate set of mechanisms.

[0015] Working principle: When using this equipment, suction bin 2 sucks the raw material from the raw material bin into the suction bin 2, and suction bin 1 sucks the clinker in the graphitization furnace chamber into the suction bin 1 through the feed bin, and then starts motor 1. When motor 1 starts, it will drive gear 1 to rotate and then gear 2 to rotate. Gear 1 and gear 2 rotate in opposite directions, so screw 1 and screw 2 also rotate in opposite directions. When screw 1 rotates, it will cause slider 1 to move away from the graphitization furnace chamber and closer to the clinker bin. At the same time, the rotation of screw 2 will cause slider 2 to move toward the feed bin and away from the raw material bin. , when the suction bin 1 moves to the bottom of the clinker bin, the suction bin 2 also moves to the bottom of the feed bin. There is no need to set up operating structures for the suction bin 1 and the suction bin 2 respectively to realize the operation of clinker and raw material, which reduces the equipment investment cost, saves installation and commissioning costs, and enhances production coordination. At this time, the motor 2 can be started. The start of the motor 2 will cause the worm to rotate. The rotation of the worm will cause the worm wheel to drive the bidirectional screw to rotate inside the support plate, thereby causing the slider 3 to move outward, thereby causing the connecting rod to rotate on the outer walls of the slider 3 and the fixed seat respectively, and drive the rectangular bar to slide on the inner wall of the gear 2 through the fixed seat to move downward, thereby causing the rectangular bar to slide on the inner wall of the gear 2. The rectangular bar drives the rectangular frame downward through the connecting rod, and then the rectangular frame drives the suction bin 2 downward through the T-shaped block 2, and the connecting block 2 moves downward and slides on the inner wall of the cylinder 2. At the same time, when the rectangular frame moves downward, the T-shaped block 1 drives the suction bin 1 downward, so that the connecting block 1 slides on the inner wall of the cylinder 1, and then the suction bin 1 and the suction bin 2 move downward synchronously, so as to achieve the effect of simultaneous and synchronous lifting of the suction bin 1 and the suction bin 2 for loading and unloading, without waiting for the loading to be completed before unloading, which greatly reduces the time interval between loading and unloading, and improves the production efficiency. When the suction bin two moves downward to the limit synchronously, the suction bin one can transport the clinker to the inside of the clinker bin, and the suction bin two can transport the raw material sucked by the suction bin two from the inside of the raw material bin to the inside of the graphitization furnace chamber for graphitization processing again. When the clinker is transported to the next link, the motor three can be started to cause the first gear to rotate, drive the second gear to rotate, and then the movable barrel can rotate to drive the ring to rotate on the inner wall of the circular groove to adjust the material discharge angle, and then the conveying angle can be adjusted according to the actual situation, making the installation of the equipment more convenient and quick, and conducive to better alignment and connection with other equipment, to ensure the normal operation of the entire production line.

[0016] The present invention provides a graphite-loading furnace device for negative electrode materials. It has the following beneficial effects:

[0017] 1. The present invention causes the slider 1 to move away from the graphitization furnace chamber by rotating the screw rod 1 and the screw rod 2 in opposite directions. At the same time, the rotation of the screw rod 2 causes the slider 2 to move toward the direction of the feed bin. The operation of the clinker and the raw material can be realized without separately setting operating structures for the suction bin 1 and the suction bin 2, thereby reducing equipment investment costs, saving installation and debugging costs, and enhancing production coordination.

[0018] 2. When the rectangular frame moves downward, the present invention prompts the T-shaped block 1 to drive the suction bin 1 to move downward, so that the connecting block 1 slides on the inner wall of the cylinder 1, and then the suction bin 1 and the suction bin 2 move downward synchronously, thereby achieving the effect of simultaneous and synchronous lifting and lowering of the suction bin 1 and the suction bin 2 for loading and unloading, without waiting for the loading to be completed before unloading, which greatly reduces the time interval for loading and unloading, and improves production efficiency.

[0019] 3. The present invention starts the motor 3 to drive the first gear to rotate, which drives the second gear to rotate, and then the movable barrel rotates, which drives the circular ring to rotate on the inner wall of the circular groove to adjust the material discharge angle. Then, the conveying angle can be adjusted according to actual conditions, making the installation of the equipment more convenient and quick, and is conducive to better alignment and connection with other equipment, ensuring the normal operation of the entire production line.
