Description

Technical Field

[0001] This invention relates to the field of spherical graphite modification production technology, and more specifically, to an apparatus and method for producing spherical graphite modification with uniform particle size. Background Technology

[0002] Lithium-ion batteries are the next generation of rechargeable batteries that followed nickel-metal hydride batteries in the 1960s. In the past decade or so, with the widespread application and rapid development of various portable electronic devices and electric vehicles, lithium-ion batteries have gained immense popularity due to their superior performance, including high reversible capacity, high voltage, high energy density, high cycle stability, long cycle life, low self-discharge, no memory effect, and no environmental pollution. They are hailed as the green energy source and dominant power source of the 21st century. Research and development of lithium-ion battery anode materials has become a key focus and hot topic for scientific research institutions. Currently, using natural spherical graphite instead of artificial graphite in lithium battery anode materials has improved energy density and cycle life.

[0003] To improve the quality of existing spherical graphite, modifiers are usually used to modify the inside of the machine casing. The modified graphite can then be processed by cutting equipment to obtain the final spherical graphite. Most existing spherical graphite production devices directly pour the graphite into the cutting equipment for cutting. Furthermore, the existing cutting production equipment has a simple structure and uses a single cutting and crushing method, resulting in poor quality and inconsistent size of the final graphite.

The present invention will be further described below with reference to the embodiments.

[0033] Please see Figures 1-8 In one embodiment of this application, a production apparatus for producing spherical graphite with uniform particle size includes a support platform 1, a corner ladder 2, a processing barrel 3, a top box 5, and a feeding funnel 9.

The production apparatus also includes a top cover 18, a drive motor 8, a cutting system, and a bagging assembly. The top cover 18 is movably disposed on the top box 5, the drive motor 8 is disposed on the top box 5 and its output end is connected to the top cover 18, the cutting system is disposed inside the top box 5 and the processing barrel 3 and is connected to the top cover 18, and the top cover 18 controls the cutting system to work and cut the graphite raw material when the top cover 18 moves, and the bagging assembly is disposed inside the support platform 1 and located on one side of the discharge machine 4, for installing and sealing bags and receiving the produced spherical graphite.

[0034] The cutting system includes a cutting and crushing component and a dust removal component. The cutting and crushing component is installed in the top box 5 and the processing barrel 3 and is connected to the feeding hopper 9. It is used to receive the graphite raw material in the feeding hopper 9 and cut the graphite raw material. The dust removal component is installed on the support platform 1 and is connected to the cutting and crushing component. When the cutting and crushing component is working, it controls the dust removal component to work and absorbs the fine dust in the processing barrel 3.

[0035] In one specific embodiment, the cutting and crushing assembly includes a feeding hopper 19, a discharging hopper 33, a primary cutting unit, a secondary cutting unit, and a driving component. The feeding hopper 19 is mounted on a top cover 18 and communicates with a feeding funnel 9. The discharging hopper 33 is movably mounted inside a processing hopper 3, with one end slidably inserted into the feeding hopper 19. The driving component is mounted inside the processing hopper 3 and connected to both the feeding hopper 19 and the discharging hopper 33. When the driving component is working, it controls the feeding hopper 19 and the discharging hopper 33 to rotate in opposite directions. The primary cutting unit is located between the feeding hopper 19 and the discharging hopper 33 and is used to perform primary cutting of the graphite raw material. The secondary cutting unit is located between the processing hopper 3 and the driving component. When the driving component is working, it controls the secondary cutting unit to work and perform secondary cutting of the graphite raw material. The feeding hopper 19 has several windows arranged around its upper ring, and dust removal screens 20 are installed in the windows.

[0036] In another specific embodiment, the top box 5 is provided with an annular box 6, the feed hopper 9 is provided on the annular box 6, the inner side of the annular box 6 is open and movably provided with a sealing ring plate 7, the sealing ring plate 7 is connected to the feeding barrel 19, and the feeding barrel 19 is connected to the feed hopper 9 through the annular box 6.

[0037] In practical applications, graphite raw materials are poured into the feeding funnel 9 on the support platform 1. The graphite raw materials can enter the processing barrel 3 along the feeding funnel 9. By placing the packaging bag directly below the discharging machine 4, the packaging bag is installed and fixed by controlling the operation of the bagging assembly. By controlling the drive motor 8 to rotate, the top cover 18 rotates. During the rotation of the top cover 18, the feeding barrel 19 and the discharging barrel 33 can rotate with it. Under the action of the drive component, the rotation direction of the feeding barrel 19 and the discharging barrel 33 can be controlled to be opposite. The system controls the secondary cutting unit to perform primary cutting of the graphite raw material. On the other hand, it can drive the secondary cutting unit to perform secondary cutting of the pre-processed graphite, thereby achieving graded cutting of the graphite raw material and finally obtaining spherical graphite, which is discharged from the discharge machine 4. While the cutting and crushing components are working, the system can also control the dust removal components to work synchronously. When the dust removal components are working, they can absorb the fine particles in the graphite raw material, increasing the purity of the produced spherical graphite. By setting the discharge machine 4, the surface smoothness of the produced spherical graphite can be guaranteed.

[0038] Please see Figures 1-8In another preferred embodiment of this application, the driving component includes a gear ring 34, a second gear 22, a guide seat 35, and a slider 36. The guide seat 35 and the gear ring 34 are both disposed on the inner wall of the processing barrel 3. The guide seat 35 is located on the side of the gear ring 34 away from the loading barrel 19. The slider 36 is movably disposed inside the guide seat 35 and is movably connected to the unloading barrel 33. The second gear 22 is sleeved on the outer wall of the loading barrel 19 and is disposed on the inner side of the gear ring 34 and meshes with the gear ring 34.

[0039] In one specific embodiment, the primary cutting unit includes a plurality of cutting blades 21 and a primary cutting disc. The primary cutting disc is disposed on the feed hopper 33 and located inside the feed hopper 19. The plurality of cutting blades 21 are arranged in a ring around the inner wall of the feed hopper 19, and the cutting blades 21 cooperate with the primary cutting disc.

[0040] In another specific embodiment, the secondary cutting unit includes a secondary crushing seat 44, a crushing chamber 45, several discharge holes 46, a cutting seat 37, a fine cutting disc 38, a transmission disc 39, and a belt 41. The secondary crushing seat 44 is disposed inside the processing barrel 3 and located on the side of the gear ring 34 away from the feeding barrel 19. The secondary crushing seat 44 is provided with a crushing chamber 45, and several discharge holes 46 are arranged in an array inside the crushing chamber 45. The cutting seat 37 is movably disposed inside the crushing chamber 45 and is connected to the slider 36. Several transmission discs 39 are equidistantly disposed on the cutting seat 37 and are connected to each other by a belt 41. Each transmission disc 39 is provided with a fine cutting disc 38. A fourth gear 42 is movably disposed on the cutting seat 37. The fourth gear 42 and one of the fine cutting discs 38 are connected by a differential 40. A drive rack 43 that meshes with the fourth gear 42 is provided on the guide seat 35.

[0041] Of course, this embodiment is not limited to the cooperation between the slider 36 and the guide seat 35 to adjust the position of the fine cutting disk 38. A linear motor or an electric cylinder can also be used instead, which will not be listed here.

[0042] When the drive motor 8 is energized and rotates, it drives the top cover 18 to rotate, which in turn drives the loading bin 19 and the unloading bin 33 to rotate synchronously. Under the meshing action between the second gear 22 and the gear ring 34, the loading bin 19 rotates as it follows the rotation of the top cover 18. During this process, under the action of the slider 36 and the guide seat 35, the unloading bin 33 can be driven to rotate in the opposite direction to the rotation of the loading bin 19. This causes the rotation directions between the cutting blade 21 and the coarse cutting disc 32 to be opposite, thereby achieving the desired effect on the unloading bin. The graphite raw material in the feeding hopper 19 is subjected to coarse cutting processing. While the slider 36 reciprocates along the guide seat 35, it can drive the cutting seat 37 to reciprocate along the secondary crushing seat 44. Under the action of the fourth gear 42 and the drive rack 43, as well as the cooperation between the transmission disc 39 and the belt 41, the fine cutting discs 38 at different positions are driven to rotate, thereby realizing the secondary cutting processing of the graphite falling into the crushing chamber 45. Finally, the graphite that has been cut and meets the standards can fall into the discharge machine 4 through the discharge hole 46.

[0043] Please see Figures 1-8 In another preferred embodiment of this application, the dust removal assembly includes a dust collection bin 29, a dust collection seat 27, a ring pipe 26, a dust storage bin 31, a fan blade 30, and a power transmission structure. The dust collection bin is mounted on the support platform 1. There are two dust collection bins 29, which are mounted on the dust storage bin 31. Each dust collection bin 29 has a fan blade 30 movably mounted inside it, and adjacent fan blades 30 are coaxially connected. The dust collection seat 27 is mounted on the processing bin 3 and is connected to the dust collection bin 29 through the ring pipe 26. The power transmission structure is mounted inside the processing bin 3 and connects the loading bin 19 and the fan blade 30. When the loading bin 19 moves, the power transmission structure controls the fan blade 30 to rotate synchronously.

[0044] In one specific embodiment, the power transmission structure includes a sleeve 23, a guide rail 24, a dust removal rack 25, and a third gear 28. The sleeve 23 is movably fitted onto the feeding hopper 19, the guide rail 24 is mounted on the sleeve 23, the dust removal rack 25 movably passes through the processing hopper 3, one end of the dust removal rack 25 is slidably engaged with the guide rail 24, and the third gear 28 is movably mounted on the dust storage bin 31 and coaxially connected with the fan blade 30. The third gear 28 and the dust removal rack 25 mesh with each other.

[0045] In another specific embodiment, the bagging assembly includes a receiving seat 10, a lifting platform 15, an adjusting motor 11, a threaded rod 12, a bag locking rod 13, a limiting rod 14, a U-shaped rack 16, and a first gear 17. The receiving seat 10 is disposed inside the support platform 1 and located on one side of the discharge machine 4. The lifting platform 15 is movably disposed on the receiving seat 10. The adjusting motor 11 is disposed on the receiving seat 10. The U-shaped rack 16 is movably disposed on the receiving seat 10. The threaded rod 12 is movably disposed on the receiving seat 10. It is connected to the output end of the adjustment motor 11. The threaded rod 12 slides through the U-shaped rack 16 and the lifting platform 15. The threaded rod 12, the U-shaped rack 16 and the lifting platform 15 are all threadedly engaged and the threading directions are opposite. Two locking rods 13 are symmetrically and movably arranged on the lifting platform 15. Two limiting rods 14 are symmetrically arranged on each locking rod 13. A first gear 17 is movably arranged on the lifting platform 15 and the first gear 17 is coaxially connected to the locking rod 13. The first gear 17 meshes with the U-shaped rack 16.

[0046] In the installation of the packaging bag, by placing the bag opening directly below the limiting rod 14, the adjusting motor 11 is energized and rotated, which drives the lifting platform 15 to move down and the U-shaped rack 16 to move up. This causes the lifting platform 15 to move down close to the packaging bag. Under the meshing action between the U-shaped rack 16 and the first gear 17, the first gear 17 and the bag locking rod 13 can be driven to rotate, causing the limiting rod 14 to rotate into the inside of the packaging bag and abut against the inside of the packaging bag, thereby realizing the installation and fixing of the packaging bag. During the movement of the feeding barrel 19 in the processing barrel 3, the dust removal rack 25 can be driven to reciprocate horizontally in the processing barrel 3. Under the meshing action between the dust removal rack 25 and the third gear 28, the third gear 28 and the fan blade 30 are driven to rotate, thereby absorbing the dust particles mixed in with the graphite raw material falling into the feeding barrel 19 through the ring pipe 26 and the dust removal net 20, ensuring the purity of the final produced round graphite.

[0047] Please see Figures 1-8 In another embodiment of this application, a method for producing spherical graphite with uniform particle size is provided, comprising the production apparatus described in the above embodiments, and the specific steps of the production method are as follows:

[0048] S100: Pour the graphite raw material into the feed funnel 9 on the support platform 1. The graphite raw material can enter the processing barrel 3 along the feed funnel 9. And by placing the packaging bag directly below the discharge machine 4, the packaging bag is installed and fixed by controlling the operation of the bagging assembly.

[0049] S200: By controlling the drive motor 8 to rotate, the top cover 18 is rotated. During the rotation of the top cover 18, the cutting and crushing components can be driven to work and perform coarse and fine cutting on the graphite raw material entering the processing barrel 3, and finally obtain spherical graphite and discharge it from the discharge machine 4.

[0050] S300: While the cutting and crushing components are working, the dust removal components can also be controlled to work synchronously. When the dust removal components are working, they can absorb the fine particles in the graphite raw materials, increasing the purity of the produced spherical graphite.
