[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with 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 of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0039] Graphite negative electrode materials are composed of artificial graphite and natural graphite. Data show that the comprehensive yield of spherical natural graphite is only about 40%. The factors limiting the yield are mainly related to particle size distribution, tap density, and specific surface area. In the existing technology, material processing equipment focuses on the crushing process, resulting in a low tap density of spherical graphite, which does not meet product specifications.

[0040] To solve this problem, the present application provides a material processing device. Figure 1 A schematic diagram of the structure of the material processing equipment provided in the embodiment of the present application, Figure 2 for Figure 1 A side view of a material processing device is shown, Figure 3 for Figure 2 The material processing equipment 100 is a schematic cross-sectional view along AA. The material processing equipment 100 includes a housing 10, and the housing 10 is provided with a processing chamber, and the processing chamber is used to accommodate the raw materials to be processed as a whole. A material feeding port is provided at the top of the housing 10, and the raw materials to be processed, such as a plurality of spherical graphite particles, can be fed through the material feeding port. The housing 10 includes a bottom wall 11, and the bottom wall 11 is arranged opposite to the material feeding port.

[0041] The material processing equipment 100 also includes a driving mechanism 20 and a crushing disc 30. The driving mechanism 20 includes a motor 21 and a driving shaft 22. The driving shaft 22 is penetrated through the bottom wall 11. The motor 21 is connected to the driving shaft 22 and is located on the side of the bottom wall 11 away from the processing chamber. Specifically, the motor can be located on one side of the housing 10. The motor 21 is a power source for the equipment and is used to provide a high speed for the equipment. The driving shaft 22 is used to drive the crushing disc 30 to rotate. The driving mechanism 20 also includes a driving shaft, a driving wheel, a driven wheel and a driven shaft. The motor 21 is connected to the driving shaft, the driving shaft is connected to the driving wheel, and the driven wheel is connected to the driving shaft 22. The driving shaft 22 is penetrated through the bottom wall 11. The driving wheel and the driven wheel are connected by a flexible transmission structure, which can be a belt or a chain.

[0042] The crushing disc 30 is arranged on the side of the bottom wall 11 facing the accommodating chamber, and the crushing disc 30 includes a disc body 31 and multiple groups of grinding block groups 32. The disc body 31 is connected to the drive shaft 22 and rotates around the drive shaft 22. The multiple groups of grinding block groups 32 are installed on the disc body 31. The number of grinding block groups 32 can be 2 groups, 3 groups, 4 groups, etc. Each group of grinding block groups 32 includes multiple grinding blocks 320 arranged at intervals. The multiple grinding blocks 320 of each group of grinding block groups 32 are arranged around the drive shaft 22, and the distances between the grinding blocks 320 of different grinding block groups 32 and the drive shaft 22 are different. A sleeve is provided in the middle of the crushing disk 30, and the driving shaft 22 is inserted into the sleeve and is rotatably connected to the crushing disk 30 through a bearing. The motor 21 rotates to drive the driving shaft 22 to rotate, thereby driving the crushing disk 30 to rotate. The crushing disk 30 has load-bearing and centrifugal functions. It uses high-speed centrifugal technology to achieve the goal of throwing the original material to the movement trajectory of the grinding block 320. The grinding block 320 can impact material particles with larger particle sizes to obtain material particles that meet the index particle size. The structure of multiple groups of grinding blocks 320 can increase the shear rate and eccentricity of the material, and achieve the purpose of shaping while ensuring the crushing effect, thereby solving the problem of low compaction density and obtaining the technical effect of both material crushing and shaping.

[0043] In some embodiments, the plurality of grinding block groups 32 at least include a first grinding block group 321 and a second grinding block group 322. The first grinding block group 321 is disposed on a side of the second grinding block group 322 away from the drive shaft 22. The first grinding block group 321 includes a plurality of first grinding blocks 3211, and the second grinding block group 322 includes a plurality of second grinding blocks 3221. Each first grinding block 3211 is disposed correspondingly between two adjacent second grinding blocks 3221, and each second grinding block 3221 is disposed correspondingly between two adjacent first grinding blocks 3211. Specifically, the first grinding block group 321 is disposed around the second grinding block group 322. In the circumferential direction of the first radius outward from the drive shaft 22 to the axis, the plurality of first grinding blocks 3211 are disposed at intervals. In the interval between two adjacent first grinding blocks 3211, a second grinding block 3221 is disposed correspondingly in the circumferential direction of the second radius from the axis, and the second radius is smaller than the first radius. The two adjacent first grinding blocks 3211 and second grinding blocks 3221 are arranged front and back, and the first grinding block group 321 and the second grinding block group 322 are staggered as a whole. The staggered structure can not only control the number of grinding blocks 320 to avoid the increase of cost and process, but also grind the material from multiple angles and directions to improve the crushing effect.

[0044] In some embodiments, the plurality of grinding block groups 32 further include a third grinding block group, the third grinding block group includes a plurality of third grinding blocks, a plurality of second grinding blocks 3221 are arranged at intervals, and in the interval between two adjacent second grinding blocks 3221, a third grinding block is correspondingly arranged in the circumferential direction of the third radius from the axis, and the third radius is smaller than the second radius. The two adjacent third grinding blocks and the second grinding blocks 3221 are arranged front and back.

[0045] See also Figure 4-Figure 6 , Figure 4 for Figure 1 A top view of the material processing equipment shown, Figure 5 for Figure 4 The schematic cross-sectional view of the material processing equipment along BB is shown. Figure 6 for Figure 5The enlarged schematic diagram of a part A of the material processing equipment 100 is shown. In some embodiments, the housing 10 includes a side wall 12, which is arranged around the bottom wall 11 to form a processing chamber. The material processing equipment 100 also includes a gear ring 40, which is arranged on the side of the side wall 12 facing the processing chamber. The gear ring 40 includes a ring body and a plurality of spaced protrusions 41, the ring body is attached to the side wall 12, and the plurality of protrusions 41 are connected to the side of the ring body facing the processing chamber, and are arranged around the plurality of grinding block groups 32. When the crushing disc 30 rotates at a high speed, a large centrifugal force is generated, and the material falls into the gap between the protrusion 41 and the grinding block 320. The grinding block 320 cooperates with the protrusion 41 to hit the material to obtain material particles that meet the index particle size. Among them, the crushing ability of the equipment is limited by the synergistic effect of the grinding block 320 and the protrusion 41. A large number of protrusions 41 will improve the crushing ability of the equipment, but the surface morphology of the material is easy to be broken. A small number of protrusions 41 will weaken the crushing ability of the equipment and increase the process cost. Since the grinding block 320 can continuously collide with the protrusion 41 during the rotation of the disk 31, the number of protrusions 41 can be greater than the number of grinding blocks 320. Those skilled in the art can set the number of protrusions 41 according to actual needs, and this application does not limit it here.

[0046] In some embodiments, each protrusion 41 includes an end face 411 facing the first grinding block 3211, and the first grinding block 3211 includes a first side face 3212 facing the protrusion 41, and the first side face 3212 is parallel to the end face 411. The end face 411 and the first side face 3212 are arranged in parallel, which helps to improve the flatness of particle grinding and avoid material morphology damage during material shaping, such as a situation where some parts are thicker and some parts are thinner. Among them, a gap is formed between the first grinding block 3211 and the gear ring 40. If the gap is too large, the material crushing standard cannot be met. If the gap is too small, the safety margin between the gear ring 40 and the first grinding block 3211 is insufficient, so the gap should be within a suitable range. Please refer to Table 1, which is a table of parameters of the gap between the grinding block and the gear ring in different situations in this application. The first line in the table is the index parameters of the material particle size Dmin (minimum particle size), D10 (particle size when the cumulative volume fraction is 10%), D50 (particle size when the cumulative volume fraction is 50%), D90 (particle size when the cumulative volume fraction is 90%), Dmax (maximum particle size), and TAP (tap density) produced by the material processing equipment. The second line in the table is the parameters of the particle size Dmin, D10, D50, D90, Dmax, and TAP of the graphite raw material to be processed. The third line in the table is the Dmin, D10, D50, D90, Dmax, and TAP parameters of the grinding block 320 and the gear ring 40 in the embodiment of the gap of 25 mm. The fourth line in the table is the Dmin, D10, D50, D90, Dmax, and TAP parameters of the grinding block 320 and the gear ring 40 in the embodiment of the gap of 20 mm. It can be seen that when the gap is within a suitable range, the particle size of the processed raw material can meet the requirements of various indicators.

[0047] Table 1

[0048]

[0049]

[0050] In some embodiments, the gap between the grinding block 320 and the gear ring 40 may be greater than or equal to 15 mm and less than or equal to 30 mm, so that the particle size of the processed raw material can meet various index requirements. Further, in some embodiments, the gap between the grinding block 320 and the gear ring 40 may be greater than or equal to 18 mm and less than or equal to 27 mm, so that the particle size of the processed raw material can meet various index requirements.

[0051] In some embodiments, when the gap between the grinding block 320 and the bump 41 is the first gap, the tap density of the raw material is increased by a first value. For example, when the gap between the grinding block 320 and the bump 41 is 25 mm, the tap density of the raw material is increased from 0.789 to 0.804. In some embodiments, the first gap may be greater than or equal to 23 mm and less than or equal to 27 mm, such as 23 mm, 23.5 mm, 24 mm, 24.5 mm, 26 mm, 26.5 mm, 27 mm, etc. In some embodiments, when the gap between the grinding block 320 and the bump 41 is the second gap, The tap density of the raw material is increased by a second value, the second gap is smaller than the first gap, and the second value is greater than the first value. For example, when the gap between the grinding block 320 and the bump 41 is 20 mm, the tap density of the raw material is increased from 0.789 to 0.819. In some embodiments, the second gap may be greater than or equal to 18 mm and less than or equal to 22 mm, such as the gap may also be 18 mm, 18.5 mm, 19 mm, 19.5 mm, 21 mm, 21.5 mm, 22 mm, etc. Compared with the first gap between the grinding block 320 and the bump 41, the tap density is significantly increased.

[0052] In some embodiments, along the direction away from the bottom wall 11, the inner diameter of the side wall 12 is inversely correlated with the distance of the side wall 12 from the bottom wall 11. Specifically, the side wall 12 surrounds the bottom wall 11 to form an opening, and the farther the opening is from the bottom wall 11, the larger the diameter of the opening. When the housing 10 rotates, the material rotating along the side wall 12 will slide down to the disc body 31, and slide to the gap between the end face 411 and the first side face 3212 under the action of centrifugation. Since the inner diameter of the side wall 12 is inversely correlated with the distance of the side wall 12 from the bottom wall 11, the multiple protrusions 41 of the gear ring 40 are arranged on the side wall 12 at an angle, so the end face 411 is arranged at an angle, and the first side face 3212 is also arranged at an angle.

[0053] In some embodiments, the first grinding block 3211 also includes a second side facing the second grinding block 3221, and the second side is perpendicular to the disc body 31. The second grinding block 3221 includes a third side facing the second side. The material collides between the first grinding block 3211 and the second grinding block 3221. In order to ensure the flatness of the material during crushing, the third side is parallel to the second side, that is, the third side is also perpendicular to the disc body 31.

[0054] See also Figure 7-Figure 9 , Figure 7 for Figure 1 The exploded diagram of the material processing equipment shown, Figure 8 for Figure 7 The enlarged schematic diagram of the material processing equipment part B is shown. Fig. 9 for Figure 7 In some embodiments, the material processing equipment 100 further includes a steel cage 50 and a tool holder 60. The steel cage 50 is disposed in the processing chamber to slow down the falling speed of the material and make the material shape uniform. The cylindrical tool holder 60 is sleeved outside the drive shaft 22 to cooperate with the grinding block 320 to complete the material shaping during the material processing process.

[0055] In some embodiments, each grinding block 320 includes a grinding plate 3201 and a mounting plate 3202, the mounting plate 3202 is fixed to the disc body 31 in the horizontal direction, and the grinding plate 3201 is connected to the side of the mounting plate 3202 away from the disc body 31 in the vertical direction. Specifically, the horizontal direction is a direction parallel to the disc body 31, and the vertical direction is a direction perpendicular to the disc body 31. The mounting plate 3202 includes a mounting surface, the mounting surface is attached to the disc body 31, and the grinding plate 3201 is perpendicular to the mounting surface. During the rotation of the disc body 31, the vertically arranged grinding plate 3201 can increase the direct contact area with the material and improve the crushing effect. In the related art, the grinding block 320 is a solid square structure. If the grinding block 320 is set as a solid structure, its weight is large. When the load increases, the motor 21 needs to generate a larger torque to drive the load to move. In order to meet the required torque, the current will increase accordingly, so the motor 21 will increase the current to achieve the required torque. When the mechanical load of the motor 21 is too large, the motor 21 will be overloaded, and the current will be large, and the internal parts of the motor 21 will be damaged or stop running directly. The structure of the grinding plate 3201 and the mounting plate 3202 can reduce the weight of the grinding block 320 and reduce the probability of equipment damage.

[0056] In some embodiments, each grinding block 320 further includes a reinforcing rib 3204, which is connected to the side of the grinding plate 3201 that is opposite to the rotation direction of the disc body 31. The reinforcing rib 3204 structure can improve the overall stability of the grinding block 320. Specifically, the grinding plate 3201 includes a first plane and a second plane that are arranged opposite to each other. When the disc body 31 rotates counterclockwise, the grinding plate 3201 rotates from the second plane to the first plane. The reinforcing rib 3204 is connected to the second plane. When the disc body 31 rotates at a high speed, the material rolls along the movement trajectory of the grinding block 320 and continuously hits the first plane. In some embodiments, when the disc body 31 rotates clockwise, the grinding plate 3201 rotates from the first plane to the second plane. The reinforcing rib 3204 is connected to the first plane. When the disc body 31 rotates at a high speed, the material rolls along the movement trajectory of the grinding block 320 and continuously hits the second plane.

[0057] In some embodiments, the reinforcing rib 3204 is connected to the mounting plate 3202, and the reinforcing rib 3204 and the mounting plate 3202 are connected to the same side of the grinding plate 3201, that is, the reinforcing rib 3204 is connected to the mounting plate 3202 and the grinding plate 3201 at the same time to improve the structural strength, wherein the reinforcing rib 3204 can be connected to the mounting plate by welding, bonding, etc.

[0058] In some embodiments, the grinding plate 3201 is connected to one end of the mounting plate 3202, and the reinforcing rib 3204 includes a first connecting edge and a second connecting edge that are perpendicular to each other, the first connecting edge is connected to the grinding plate 3201, and is extended from one end of the grinding plate 3201 to the other end of the grinding plate 3201, and the second connecting edge is connected to the mounting plate 3202, and is extended from one end of the mounting plate 3202 to the other end. Specifically, the reinforcing rib 3204 structure can be a right-angled triangle structure, the grinding plate 3201 and the mounting plate 3202 form an L-shaped structure, and the reinforcing rib 3204 is connected between the grinding plate 3201 and the mounting plate 3202. In some embodiments, the length of the first connecting edge is the same as the length of the grinding plate 3201, and the length of the second connecting edge is the same as the length of the mounting plate 3202. In some embodiments, the length of the first connecting edge may be smaller than the length of the grinding plate 3201, and the length of the second connecting edge may be smaller than the length of the mounting plate 3202, such as the first connecting edge extends from one end of the grinding plate 3201 to the middle of the grinding plate 3201, and the second connecting edge extends from one end of the mounting plate 3202 to the middle of the mounting plate 3202.

[0059] In some embodiments, the reinforcing rib 3204 is directly connected to the disc body 31 , and the mounting plate 3202 can be connected to a side of the grinding plate 3201 facing away from the reinforcing rib 3204 .

[0060] In some embodiments, the reinforcing ribs 3204, the grinding plate 3201 and the mounting plate 3202 may be an integrally formed structure, which may increase structural stability and save processing steps.

[0061] In some embodiments, the material processing equipment 100 further includes a plurality of fasteners. The mounting plate 3202 is provided with mounting holes 3203 on both sides of the reinforcing rib 3204. There is one mounting hole 3203 on each side, or there may be multiple mounting holes on each side. The disk body 31 is provided with through holes corresponding to the mounting holes 3203. Each fastener is correspondingly inserted through the mounting holes 3203 and the through holes so that the mounting plate 3202 is fixed to the disk body 31. The fasteners may be screws, studs, bolts, etc. In some embodiments, the mounting plate 3202 and the disk body 31 are connected by other detachable means, such as plug-in holes on both sides of the reinforcing rib 3204, and the disk body 31 is provided with plug-in columns, which are correspondingly plugged into the plug-in holes; in some embodiments, the mounting plate 3202 and the disk body 31 are also connected by non-detachable means such as welding, which is not limited in this application.
