Description

Technical Field

[0001] This utility model relates to the technical field of battery negative electrode material preparation, specifically to a spherical graphite shaping device. Background Technology

[0002] Graphite, as a lithium-ion battery anode material, possesses advantages such as good conductivity, excellent charge / discharge voltage platform, and high specific capacity, and has been widely used in lithium-ion batteries. The shape, tap density, and specific surface area of ​​graphite particles are all closely related to the lithium intercalation performance of graphite materials. However, different graphite processing methods result in variations in these physicochemical properties. Effective control of the physicochemical indicators of graphite anode materials during research and production is crucial to obtaining graphite anode materials with excellent lithium intercalation performance.

[0003] The spheroidization of graphite particles is crucial for improving the electrical properties of natural graphite powder. Better sphericity results in higher tap density, better isotropy, and superior charge-discharge performance of the resulting battery. However, existing spherical graphite production processes are limited, leading to low efficiency, high energy consumption, and high costs. Furthermore, the sphericity of the produced graphite is often inconsistent, resulting in suboptimal product performance and failing to meet rapidly evolving market demands. Current graphite shaping equipment suffers from both complex structures and high energy consumption, while other equipment exhibits poor shaping results.

[0004] As can be seen from the above, existing graphite shaping equipment suffers from problems such as complex structure and poor shaping effect. Utility Model Content

The spherical graphite shaping device includes a housing, a first gear ring, a second gear ring, and a drive assembly. The housing has an inlet and an outlet. The first gear ring is fixedly disposed inside the housing, and the second gear ring is rotatably disposed inside the first gear ring. The first gear ring and the second gear ring each have protruding teeth facing each other. An annular gap is formed between the first gear ring and the second gear ring, and the gap communicates with the inlet and the outlet. The gap gradually decreases along the direction from the top to the bottom of the housing. The drive assembly is disposed on the housing and is drivenly connected to the second gear ring.

[0007] Furthermore, the first gear ring is a conical structure with a top opening diameter larger than the bottom opening diameter, and the second gear ring includes a surrounding plate and a baffle. The surrounding plate is a conical structure with a top opening diameter larger than the bottom opening diameter, and the baffle is disposed at the bottom opening of the surrounding plate. The drive assembly is drivenly connected to the baffle, and a gap is formed between the inner circumferential surface of the first gear ring and the outer circumferential surface of the surrounding plate of the second gear ring.

[0008] Furthermore, the first gear ring and the second gear ring are coaxial with the output shaft of the housing and the drive assembly; and / or the cone angle of the first gear ring is β, and the cone angle of the enclosure is α, where α and β satisfy α > β; and / or the cone angle of the enclosure is α, where α satisfies α ≤ 150°.

[0009] Furthermore, the second gear ring also includes a cover plate, which is detachably disposed at the top opening of the enclosure.

[0010] Furthermore, the gap is H, where H satisfies 2mm≤H≤30mm.

[0011] Furthermore, the outer shell includes a first shell, a second shell, and a third shell. The first shell has a feeding chamber that communicates with the top of the gap. The feeding port is located on the top surface of the first shell and communicates with the feeding chamber. The spherical graphite shaping equipment also includes a feeding hopper that is located on the top surface of the first shell and communicates with the feeding port. The second shell is located at the bottom of the first shell. The first gear ring is located inside the second shell. The third shell is located at the bottom of the second shell. The third shell has a discharge chamber that communicates with the bottom of the gap. The discharge port is located on the side wall of the third shell and communicates with the discharge chamber.

[0012] Furthermore, the second housing has a conical structure, and the diameter of the end where the second housing connects to the third housing is greater than the diameter of the end where the second housing connects to the first housing. The outer circumferential surface of the first gear ring is fitted and fixed to the inner circumferential surface of the second housing.

[0013] Furthermore, the drive assembly includes a drive component, a transmission component, and an output shaft. The drive component is located on the outside of the housing. The first end of the output shaft passes through the third housing and is driven to connect with the baffle of the second gear ring. The second end of the output shaft is located on the bottom side of the third housing. The transmission component is located at the second end of the output shaft. The drive component is driven to connect with the output shaft through the transmission component.

[0014] Furthermore, the spherical graphite shaping equipment also includes bearings and gaskets. The bearings are mounted on the third housing and located inside the discharge chamber. The bearings are sleeved on the output shaft, and the gaskets are abutted between the top surface of the bearing and the bottom surface of the baffle.

[0015] Furthermore, the tip of the convex tooth has a circular arc structure.

[0016] According to the technical solution of this utility model, the spherical graphite shaping equipment includes a shell, a first gear ring, a second gear ring, and a drive assembly. The shell has an inlet and an outlet. The first gear ring is fixedly disposed inside the shell, and the second gear ring is rotatably disposed inside the first gear ring. The first gear ring and the second gear ring each have protruding teeth facing each other. An annular gap is formed between the first gear ring and the second gear ring, and the gap communicates with the inlet and the outlet. The gap gradually decreases along the direction from the top to the bottom of the shell. The drive assembly is disposed on the shell and is drivenly connected to the second gear ring.

[0017] As can be seen from the above, the spherical graphite shaping equipment of this application uses a second gear ring rotating inside the first gear ring, creating a speed difference between the second and first gear rings. While the second gear ring rotates, it drives the graphite particles inside the gap to rotate synchronously. Under the action of the centrifugal force of the second gear ring, the graphite particles collide between the first and second gear rings, and then the graphite particles are kneaded by the convex teeth of the first and second gear rings to shape the graphite particles into spherical shapes. The structure of this application is simple and easy to operate. Furthermore, by repeatedly kneading the graphite particles rotating circumferentially along the first gear ring through the convex teeth of the first and second gear rings, the shaping effect of the graphite particles is improved.

[0018] The gap between the first and second gear rings in this application is designed to gradually decrease from top to bottom, which provides a certain resistance to the downward movement of graphite particles, delays the time it takes for graphite particles to pass through the gap, and is conducive to improving the shaping effect.

[0030] To address the problems of complex structure and poor shaping effect in existing graphite shaping equipment, this application provides a spherical graphite shaping device.

[0031] Among them, the spherical graphite shaping equipment is used to shape graphite particles into spherical graphite particles, thereby increasing the density of graphite particles and thus improving the performance of the battery.

[0032] like Figures 1 to 5 As shown, the spherical graphite shaping device includes a housing 10, a first gear ring 20, a second gear ring 30, and a drive assembly. The housing 10 has an inlet and an outlet 132. The first gear ring 20 is fixedly disposed inside the housing 10, and the second gear ring 30 is rotatably disposed inside the first gear ring 20. The first gear ring 20 and the second gear ring 30 respectively have convex teeth facing each other. An annular gap 40 is formed between the first gear ring 20 and the second gear ring 30. The gap 40 communicates with the inlet and the outlet 132. The drive assembly is disposed on the housing 10 and is drivenly connected to the second gear ring 30 to provide driving force for the rotation of the second gear ring 30.

[0033] In this process, graphite particles enter the interior of the outer shell 10 through the feed port at the top of the outer shell 10 and enter the gap 40. In the gap 40, the graphite particles are impacted and kneaded by the protruding teeth of the first toothed ring 20 and the second toothed ring 30 and gradually move downward. After the graphite particles form a spherical structure, they are discharged from the discharge port 132 at the bottom of the outer shell 10.

[0034] The spherical graphite shaping device of this application uses a second gear ring 30 rotating inside a first gear ring 20, creating a speed difference between the second gear ring 30 and the first gear ring 20. As the second gear ring 30 rotates, it drives the graphite particles inside the gap 40 to rotate synchronously. Under the centrifugal force of the second gear ring 30, the graphite particles collide between the first gear ring 20 and the second gear ring 30, and are thus kneaded by the convex teeth of the first gear ring 20 and the second gear ring 30, forming spherical graphite particles. This application has a simple structure, is easy to operate, and improves the shaping effect of graphite particles by repeatedly kneading the graphite particles rotating circumferentially along the first gear ring 20 through the convex teeth of the first gear ring 20 and the second gear ring 30.

[0035] In this embodiment, the ends of the protruding teeth of the first tooth ring 20 and the second tooth ring 30 facing each other are the tooth tips. The tooth tips of the two protruding teeth on the two tooth rings are both arc-shaped structures. The use of arc-shaped tooth tips is beneficial to kneading and shaping the graphite particles inside the gap 40 into a spherical structure.

[0036] like Figure 1 As shown, the gap 40 is formed on the outer periphery of the second gear ring 30 and located on the inner periphery of the first gear ring 20. The gap 40 is formed as an annular space along the circumference of the first gear ring 20 and the second gear ring 30 to accommodate graphite particles. The gap 40 gradually decreases in the direction from the top to the bottom of the outer shell 10.

[0037] Wherein, the gap 40 is the distance between the first gear ring 20 and the second gear ring 30, and the distance between the first gear ring 20 and the second gear ring 30 gradually decreases along the direction from the top to the bottom of the outer shell 10.

[0038] The gap 40 between the first toothed ring 20 and the second toothed ring 30 in this application adopts a structure that gradually decreases from top to bottom. This provides a certain resistance to the downward movement of graphite particles, delays the time it takes for the graphite particles to pass through the gap 40, and is beneficial to improving the shaping effect. Specifically, the gradually decreasing gap 40 in this application slows down the downward movement speed of the graphite particles, prolongs the shaping time of the graphite particles between the first toothed ring 20 and the second toothed ring 30, and also creates a speed difference in the downward movement of the graphite particles, increasing the probability of collision between the graphite particles, thereby improving the shaping effect.

[0039] In this embodiment, the gap 40 is H, as can be seen in... Figure 1 As shown, H satisfies 2mm≤H≤30mm. The minimum distance of the gap 40 in this application is 2mm, that is, the minimum distance between the first gear ring 20 and the second gear ring 30 is 2mm; the maximum distance of the gap 40 is 30mm, that is, the maximum distance between the first gear ring 20 and the second gear ring 30 is 30mm; specifically, the value of the gap 40H gradually decreases along the direction from the top to the bottom of the outer shell 10. It can be understood that the value of the gap 40H at different positions along the direction from the top to the bottom of the outer shell 10 in this application is different, specifically to form a structure in which the gap 40 gradually decreases.

[0040] Specifically, in this embodiment, when H satisfies 2mm≤H≤30mm, the graphite particles inside the gap 40 can be effectively shaped to form spherical particles. When H is too small, it is not conducive to the smooth movement of the particles to the discharge port 132, and jamming may occur, causing the equipment to malfunction. When H is too large, it affects the shaping efficiency of the graphite particles.

[0041] like Figure 1 , Figure 4 and Figure 5 As shown, the first gear ring 20 is a conical structure with a top opening diameter larger than the bottom opening diameter, specifically a frustum structure with top and bottom openings.

[0042] The second gear ring 30 includes a surrounding plate 310 and a baffle 320. The surrounding plate 310 is a conical structure with a top opening diameter larger than the bottom opening diameter. The baffle 320 is located at the bottom opening of the surrounding plate 310. The drive assembly is driven to connect with the baffle 320. A gap 40 is formed between the inner circumferential surface of the first gear ring 20 and the outer circumferential surface of the surrounding plate 310 of the second gear ring 30. The structure of the first gear ring 20 and the surrounding plate 310 is such that the top diameter is larger than the bottom diameter. Therefore, when the graphite particles move inside the gap 40, the resistance increases sequentially, generating a shaping force of squeezing and kneading on the graphite particles, causing the graphite particles to curl or become rounded after being subjected to force.

[0043] Among them, the enclosure 310 is a frustum structure with openings at the top and bottom, the baffle 320 is formed as the bottom surface of the frustum structure, the output shaft 70 of the drive component is fixedly connected to the baffle 320, so that the drive component drives the second gear ring 30 to rotate. The centrifugal force generated by the rotation of the second gear ring 30 increases from top to bottom, and the impact force between the graphite particles and the second gear ring 30 also increases from top to bottom, providing the power required for the spherical graphite particles to gradually curl or become rounded into spheres.

[0044] In this embodiment, the second gear ring 30 further includes a cover plate 330, which is detachably disposed at the top opening of the surrounding plate 310. The cover plate 330 blocks the top opening of the surrounding plate 310 to prevent graphite particles from entering the inner cavity of the second gear ring 30. Opening the cover plate 330 allows operation of the components inside the inner cavity of the second gear ring 30. The cover plate 330 may be fixed to the top surface of the second gear ring 30 by fasteners such as bolts.

[0045] In this embodiment, the first gear ring 20 and the second gear ring 30 are coaxial with the outer shell 10 and the output shaft 70 of the drive assembly. The coaxial arrangement of the first gear ring 20 and the second gear ring 30 ensures the uniformity of the gap 40, thereby ensuring that the graphite particles inside the gap 40 form round and uniform spherical particles. The coaxial arrangement of the output shaft 70 and the second gear ring 30 helps to ensure the stability of the rotation of the second gear ring 30, and also avoids the eccentric rotation of the second gear ring 30, which would cause uneven force on the graphite particles in the circumferential direction. The coaxial arrangement of the outer shell 10 and the first gear ring 20 helps to improve the stability of the overall structure.

[0046] like Figures 2 to 5 As shown, the cone angle of the first gear ring 20 is β, and the cone angle of the surrounding plate 310 is α. α and β satisfy α > β.

[0047] Specifically, the cone angle of the enclosure 310 is greater than the cone angle of the first gear ring 20, thereby ensuring that the gap 40 gradually decreases along the direction from the top to the bottom of the outer shell 10, so as to delay the time for graphite particles to pass through the gap 40, which is beneficial to improving the shaping effect.

[0048] Furthermore, the cone angle of the enclosure 310 is α, which satisfies α≤150° to ensure the stability of the graphite particles in the gap 40. When α is greater than 150°, it is not conducive to the movement of graphite particles in the gap 40, which makes it impossible to smoothly shape and discharge the graphite particles, thus affecting the efficiency of the equipment.

[0049] like Figure 1 As shown, the outer shell 10 also has a feed chamber 111 communicating with the top end of the gap 40. The feed chamber 111 is connected to the feed inlet to facilitate the storage of graphite particles supplied to the interior of the outer shell 10 by the feed inlet and to supply the graphite particles to the gap 40. The outer shell 10 also has a discharge chamber 131 communicating with the bottom end of the gap 40. The discharge chamber 131 is connected to the discharge outlet 132 and is used to accommodate the spherical graphite particles that will be shaped inside the gap 40.

[0050] Specifically, the outer casing 10 includes a first casing 110, a second casing 120 and a third casing 130 connected sequentially along the height direction. The first casing 110 and the second casing 120 are fixedly connected by fasteners such as bolts, and the second casing 120 and the third casing 130 are fixedly connected by fasteners such as bolts.

[0051] The first housing 110 is located above the second housing 120 and the third housing 130. The first housing 110 has a feeding chamber 111, which is connected to the top of the gap 40. The feeding port is located on the top surface of the first housing 110 and is connected to the feeding chamber 111. Graphite particles are supplied to the inside of the feeding chamber 111 through the feeding port.

[0052] The spherical graphite shaping equipment of this application also includes a feeding hopper 140, which is disposed on the top surface of the first housing 110 and communicates with the feed inlet. The feeding hopper 140 is formed as a funnel structure, and the bottom opening of the feeding hopper 140 is communicated with the feed inlet. The structural arrangement of the feeding hopper 140 is conducive to improving the convenience of graphite particle supply and improving the efficiency of equipment use.

[0053] In this embodiment, the first toothed ring 20 is disposed inside the second housing 120 and fixedly connected to the second housing 120. The second housing 120 has a conical structure, and the diameter of the end of the second housing 120 connected to the third housing 130 is larger than the diameter of the end of the second housing 120 connected to the first housing 110. The outer circumferential surface of the first toothed ring 20 is fitted and fixed to the inner circumferential surface of the second housing 120. Both the second housing 120 and the first toothed ring 20 are formed into conical structures, and the surface-to-surface fitting and fixing method between the second housing 120 and the first toothed ring 20 is beneficial to improving the stability of the fixing of the first toothed ring 20. At the same time, the conical structure of the second housing 120 helps to reduce space occupation.

[0054] The first gear ring 20 and the second housing 120 can be fixed by welding or by fasteners such as bolts.

[0055] like Figure 1 As shown, the third housing 130 has a discharge chamber 131, which is connected to the bottom end of the gap 40. The discharge port 132 is provided on the side wall of the third housing 130 and is connected to the discharge chamber 131 for discharging spherical graphite particles.

[0056] Specifically, the output shaft 70 passes through the discharge chamber 131 and is fixedly connected to the baffle 320 of the second gear ring 30.

[0057] In this embodiment, the drive assembly includes a drive member, a transmission member 80, and an output shaft 70. The drive member is disposed on the outside of the housing 10. The first end of the output shaft 70 passes through the third housing 130 and is driven to connect with the baffle 320. The second end of the output shaft 70 is disposed on the bottom side of the third housing 130. The transmission member 80 is disposed on the second end of the output shaft 70. The drive member is driven to connect with the output shaft 70 through the transmission member 80.

[0058] The driving component can be a motor, and the transmission component 80 can be a pulley. The motor drives the pulley to rotate via a belt, and the pulley drives the output shaft 70 to rotate. The transmission component 80 can also be a sprocket. The motor drives the sprocket to rotate via a chain, and the sprocket drives the output shaft 70 to rotate. The transmission component 80 can also be a first gear, and a second gear is fitted on the motor. The output shaft 70 is driven to rotate through the meshing of the first gear and the second gear.

[0059] In this embodiment, the spherical graphite shaping device also includes a bearing 50, which is disposed on the third housing 130 and located inside the discharge chamber 131. The bearing 50 is sleeved on the output shaft 70, and the baffle 320 of the second gear ring 30 is disposed on the top surface of the bearing 50.

[0060] Specifically, the bottom end of the bearing 50 is fixed to the bottom surface of the discharge chamber 131 by fasteners such as bolts. The bearing 50 is on the bottom surface of the baffle 320 that supports the second gear ring 30. The first end of the output shaft 70 passes through the baffle 320. A nut is rotatably provided on the first end of the output shaft 70. The nut abuts against the top surface of the baffle 320. The nut and the bearing 50 clamp and fix the baffle 320 of the second gear ring 30 along the height direction of the outer shell 10, thereby realizing the stable placement of the second gear ring 30 inside the outer shell 10.

[0061] In this embodiment, the spherical graphite shaping device further includes a shim 60, which is abutted between the top surface of the bearing 50 and the bottom surface of the baffle 320. The bearing 50 supports the baffle 320 of the second gear ring 30 through the shim 60. The shim 60 is a replaceable structural component; replacing it with shims of different thicknesses allows adjustment of the setting height of the second gear ring 30. Adjusting the setting height of the second gear ring 30 allows adjustment of the gap 40, thus adapting it to spherical graphite particles with corresponding diameter requirements, thereby increasing the applicability of the spherical graphite shaping device. Furthermore, this application only requires replacing the shim 60 to be applicable to the shaping of different spherical graphite particles, making operation simple, convenient, and improving operational efficiency.

[0062] The spherical graphite shaping equipment in this embodiment operates as follows: Graphite particles to be shaped are fed into the feeding chamber 111 through the feeding hopper 140. Under the influence of gravity, the graphite particles enter the gap 40 for shaping. The output shaft 70 of the drive assembly drives the second gear ring 30 to rotate. Under the impact force of the second gear ring 30, the graphite particles are repeatedly impacted and shaped by the first gear ring 20. The rubbing action of the protruding teeth of the first and second gear rings 20 shapes the graphite particles into a spherical structure. Because the second gear ring 30 is a conical structure with a top diameter smaller than its bottom diameter, the centrifugal force generated by the circumferential rotation of the second gear ring 30 from above... The centrifugal force increases sequentially downwards, slowing down the downward movement of the graphite particles. This prolongs the shaping time of the graphite particles between the first toothed ring 20 and the second toothed ring 30, and also creates a speed difference for the downward movement of the upper graphite particles, increasing the probability of collision between the graphite particles. Similarly, the gap 40 in this application, which is larger at the top and smaller at the bottom, also slows down the downward movement of the graphite particles, prolongs the shaping time of the graphite particles between the first toothed ring 20 and the second toothed ring 30, and also creates a speed difference for the downward movement of the graphite particles, increasing the probability of collision between the graphite particles. The shaped spherical graphite particles enter the discharge chamber 131 and are discharged through the discharge port 132.

[0063] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0064] The spherical graphite shaping device of this application uses a second gear ring 30 rotating inside a first gear ring 20, creating a speed difference between the second gear ring 30 and the first gear ring 20. As the second gear ring 30 rotates, it drives the graphite particles inside the gap 40 to rotate synchronously. Under the centrifugal force of the second gear ring 30, the graphite particles collide between the first gear ring 20 and the second gear ring 30, and are thus kneaded by the convex teeth of the first gear ring 20 and the second gear ring 30, forming spherical graphite particles. This application has a simple structure, is easy to operate, and improves the shaping effect of graphite particles by repeatedly kneading the graphite particles rotating circumferentially along the first gear ring 20 through the convex teeth of the first gear ring 20 and the second gear ring 30.

[0065] The gap 40 between the first gear ring 20 and the second gear ring 30 in this application adopts a structure that gradually decreases from top to bottom, which provides a certain resistance to the downward movement of graphite particles, delays the time it takes for graphite particles to pass through the gap 40, and is conducive to improving the shaping effect.
