Description

Technical Field

[0001] This utility model relates to the field of materials processing technology, and more specifically, to a materials processing device and a materials processing machine. Background Technology

[0002] With the increasing demand for industrial automation and precision manufacturing, material processing equipment is playing an increasingly important role in various fields such as chemical, pharmaceutical, and food processing. The main function of these devices is to process raw materials into particles with specific shapes and sizes to meet the needs of subsequent processes.

[0003] Taking the shaping and preparation of spherical graphite as an example, graphite is mainly divided into two categories: natural graphite and artificial graphite. Natural flake graphite materials, as lithium battery anode materials, have advantages such as good conductivity, excellent charge and discharge voltage platform, and high specific capacity, and have been widely used in commercial lithium-ion batteries. Compared with natural graphite, artificial graphite has a highly ordered layered crystal structure, a high degree of graphitization, regular interlayer arrangement, and fewer crystal defects. This structure makes the insertion / extraction of lithium ions between layers smoother, which is beneficial to improving the charge and discharge performance, cycle performance, and rate performance of the battery. However, artificial graphite is inferior to natural graphite in terms of morphology. Natural graphite has a more regular shape, a relatively smooth surface, and a relatively narrow particle size distribution; while the raw material of artificial graphite has poor toughness and is crushed and shaped by strong instantaneous mechanical force. Through further classification to achieve the target particle size, the morphology is irregular and has more surface edges. Therefore, the difference in morphology makes artificial graphite slightly inferior to natural graphite in terms of energy density, interfacial performance, and lithium-ion transport.

[0004] In existing methods for processing and preparing artificial graphite, single particles are typically stacked into spherical secondary particles by further granulating the pulverized material. However, the particle surfaces are relatively rough, resulting in poor processing quality.

[0005] As can be seen from the above, the existing technology has the problem of poor processing effect of particulate materials. Utility Model Content

[0006] The main objective of this invention is to provide a material processing device and a material processing machine to solve the problem of poor processing effect of particulate materials in the prior art.

[0007] To achieve the above objectives, according to one aspect of the present invention, a material processing apparatus is provided, comprising: a housing having a receiving cavity; a hammerhead disc rotatably disposed within the receiving cavity; and multiple hammerheads spaced circumferentially on the axial end face of the hammerhead disc, with the length direction of the hammerheads parallel to the radial direction passing through the center of the axial end face; each hammerhead includes a first working part and a second working part connected in sequence, the top end of the first working part being arc-shaped, and the width of the first working part being greater than the width of the second working part, the first working part protruding from the outer periphery of the hammerhead disc.

[0008] Furthermore, the second working part includes a first plate and a second plate, the first plate being connected to the axial end face, and the second plate being placed upright on the first plate.

[0009] Furthermore, at least one side of the first plate relative to the second plate is provided with a notch, and there are multiple notches, which are spaced apart along the length of the first plate.

[0010] Furthermore, the width of the end of the first plate that is connected to the first working part gradually increases in the direction close to the first working part.

[0011] Furthermore, the material processing device also includes a liner plate disposed on the inner wall surface of the housing. The liner plate includes a plurality of first grinding columns and a plurality of second grinding columns parallel to the rotation axis of the hammer head disk. The plurality of first grinding columns and the plurality of second grinding columns are arranged circumferentially along the inner wall surface of the housing. The first grinding columns and the second grinding columns have different shapes, and there is at least one first grinding column between two adjacent second grinding columns.

[0012] Furthermore, the first grinding column is a circular column, and the second grinding column is conical on the side facing the hammerhead.

[0013] Furthermore, the minimum distance d between the hammer head and the liner plate and the diameter D of the hammer head disk satisfy the following: 0.3% ≤ d / D ≤ 0.5%; and / or the minimum distance d between the hammer head and the liner plate is 5mm to 7mm.

[0014] Furthermore, the material processing device also includes a third grinding column, which is disposed on the inner wall surface of the housing and protrudes toward the hammer head disk.

[0015] Furthermore, the length L of the hammer head and the diameter D of the hammer head disc satisfy the following: 15% ≤ L / D ≤ ​​20%; and / or the diameter D of the hammer head disc is 1500mm to 2000mm.

[0016] According to another aspect of the present invention, a material processing machine is provided, comprising the material processing apparatus described above.

[0017] The present invention provides a material processing device comprising a housing, a hammer disk, and hammers. The housing has a receiving cavity, and the hammer disk is rotatably disposed within the receiving cavity. Multiple hammers are spaced circumferentially on the axial end face of the hammer disk, with the length direction of the hammers parallel to the radial direction passing through the center of the axial end face. Each hammer includes a first working part and a second working part connected sequentially. The top of the first working part is arc-shaped, and its width is greater than that of the second working part. The first working part protrudes from the outer periphery of the hammer disk. By providing rotatable hammers within the receiving cavity, and by having an arc-shaped top and a large width in the first working part protruding from the outer periphery of the hammer disk, the direction of the granular material's rebound after colliding with the hammers is increased. This increases the opportunities for compression, friction, and collision between granular materials, and between granular materials and the hammers and the inner wall of the housing after the granular material enters the receiving cavity. This improves the processing efficiency and effect of the granular material, solving the problem of poor processing effect of granular materials in the prior art. Attached Figure Description

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0030] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0031] To address the problem of poor processing effect of granular materials in existing technologies, this utility model provides a material processing device and a material processing machine.

[0032] In this embodiment, the material processing apparatus and process of this application will be specifically described using the shaping and preparation of graphite particles as an example. That is, in this embodiment, the material processing apparatus is a graphite particle shaping apparatus; it can be understood that when graphite particles are shaped and prepared, the particle material is graphite particles. Of course, the material processing apparatus can also be an apparatus for other purposes, and can be selected according to actual needs.

[0033] like Figures 1 to 5As shown, the material processing device includes a housing 10, a hammer disk 20, and hammers 30. The housing 10 has a receiving cavity. The hammer disk 20 is rotatably disposed within the receiving cavity. Multiple hammers 30 are arranged circumferentially on the axial end face of the hammer disk 20, with the length direction of each hammer 30 parallel to the radial direction passing through the center of the axial end face. Each hammer 30 includes a first working part 31 and a second working part 32 connected sequentially. The top end of the first working part 31 is arc-shaped, and the width of the first working part 31 is greater than the width of the second working part 32. The first working part 31 protrudes from the outer periphery of the hammer disk 20. It can be understood that the top end of the first working part 31 is the end protruding from the outer periphery of the hammer disk 20.

[0034] This application provides a rotatable hammerhead 30 within the accommodating cavity. The first working part 31 of the hammerhead 30, which protrudes from the outer periphery of the hammerhead disk 20, has an arc-shaped top and a large width. This increases the direction of the granular material's springback after colliding with the hammerhead 30, resulting in a higher chance of compression, friction, and collision between granular materials and between granular materials and the inner wall of the hammerhead 30 and the housing 10 after the granular material enters the accommodating cavity. This improves the processing efficiency and effectiveness of the granular material.

[0035] It should be noted that in this embodiment, the length direction of the hammer head 30 is... Figure 3 The left and right directions indicated by L in the middle correspond to the width direction of the hammer head 30. Figure 3 The up and down directions in the middle.

[0036] In this embodiment, the hammerhead 30 is made of alloy material.

[0037] Furthermore, such as Figures 3 to 5 As shown, the second working part 32 includes a first plate 321 and a second plate 322. The first plate 321 is connected to the axial end face of the hammerhead disk 20, and the second plate 322 is placed vertically on the first plate 321. Specifically, the second plate 322 is located in the middle of the first plate 321. It can be understood that the material processing device in this embodiment is horizontally arranged, that is, the rotation axis of the hammerhead disk 20 is a horizontal axis. Correspondingly, the first plate 321 is vertically arranged and fits against the axial end face of the hammerhead disk 20, while the second plate 322 is horizontally arranged and protrudes from the axial end face of the hammerhead disk 20. By setting the second working part 32 as a T-shaped structure, both the vertically arranged first plate 321 and the second plate 322 can collide with the graphite particles, thereby improving the crushing and shaping effect. Moreover, the second plate 322 can firmly connect the first plate 321 and the first working part 31 together, improving the structural strength of the hammerhead 30.

[0038] Furthermore, such as Figures 3 to 4As shown, at least one side of the first plate 321 relative to the second plate 322 is provided with a notch 3211, and there are multiple notches 3211, which are spaced apart along the length direction of the first plate 321.

[0039] In this embodiment, notches 3211 are provided on both sides of the first plate 321 relative to the second plate 322. This arrangement creates a concave-convex structure on both sides of the first plate 321, allowing the graphite particles to collide multiple times within this structure, thereby improving the pulverization effect. Alternatively, the notch 3211 can be provided on only one side of the first plate 321 relative to the second plate 322, depending on the specific requirements.

[0040] In this embodiment, the notch 3211 is rectangular. The rectangular notch 3211 has obvious edges and corners, which is beneficial for the collision of graphite particles in the uneven structure.

[0041] In this embodiment, the width of the end of the first plate 321 connected to the first working part 31 gradually increases along the direction close to the first working part 31. Specifically, both sides of the end of the first plate 321 connected to the first working part 31 are arc-shaped. This configuration allows the first plate 321 to be more firmly connected to the first working part 31, improving the overall structural strength of the hammer head 30. Furthermore, the second plate 322 is also connected and fixed to the bottom end face of the first working part 31, and the second plate 322 is flush with the outer surface of the first working part 31.

[0042] In the technical solution of this application, the first working part 31 with an arc shape at the front end of the hammer 30 is used to rebound the material, causing the material to collide in multiple directions, thereby achieving the effect of shaping graphite particles. The first plate 321 with an uneven structure at the rear impacts, shears, and crushes the graphite particles through multiple sharp edges. This crushing and shaping method using a two-stage hammer structure with cyclic impact provides high shaping strength and modifies the morphology, allowing the graphite particles to be gradually shaped from irregular amorphous particles into smooth, potato-like particles in the material processing device. This results in higher tap density and a smaller specific surface area, thereby improving the circulation performance of the graphite particles after processing.

[0043] like Figures 1 to 2 , Figure 6 As shown, the material processing apparatus also includes a liner 40. The liner 40 is disposed on the inner wall surface of the housing 10. The liner 40 includes a plurality of first grinding pillars 41 and a plurality of second grinding pillars 42 parallel to the rotation axis of the hammerhead disc 20. The plurality of first grinding pillars 41 and the plurality of second grinding pillars 42 are arranged circumferentially along the inner wall surface of the housing 10. The first grinding pillars 41 and the second grinding pillars 42 have different shapes, and at least one first grinding pillar 41 is located between two adjacent second grinding pillars 42.

[0044] It is understood that the number of first grinding pillars 41 is greater than or equal to the number of second grinding pillars 42. In this embodiment, there are three first grinding pillars 41 between adjacent second grinding pillars 42. Of course, the above-mentioned number setting is not limited and can be selected according to actual needs.

[0045] In this embodiment, the first grinding column 41 is a circular column, and the second grinding column 42 is conical on the side facing the hammerhead disk 20. In fact, the second grinding column 42 can be considered as being formed by cutting the side of the first grinding column 41 facing the hammerhead disk 20 with two cuts. Through this arrangement, the combination of the two grinding columns can simultaneously pulverize graphite particles and modify their morphology, improving the pulverization and shaping effect.

[0046] Furthermore, such as Figures 1 to 2 As shown, the material processing device also includes a third grinding column 50. The third grinding column 50 is disposed on the inner wall surface of the housing 10, and the third grinding column 50 protrudes toward the hammer head disk 20. It can be understood that the first grinding column 41 and the second grinding column 42 are horizontally arranged, while the third grinding column 50 is arranged along a vertical plane.

[0047] In this embodiment, as Figure 2 As shown, the minimum distance d between the hammerhead 30 and the liner plate 40 satisfies the following relationship with the diameter D of the hammerhead disc 20: 0.3% ≤ d / D ≤ 0.5%. Furthermore, the minimum distance d between the hammerhead 30 and the liner plate 40 is 5mm to 7mm. Through the above settings, the ratio in this embodiment is much smaller than the ratio of the distance between the hammerhead disc and the distance between the hammerhead disc in general crushing equipment, and the uniform distribution of the gaps around the edges improves the uniformity of graphite particle distribution in the material processing device, thereby increasing the shaping efficiency. At the same time, the reduced distance increases the probability of material collision, resulting in a better crushing and shaping effect.

[0048] In this embodiment, as Figures 2 to 3 As shown, the length L of the hammerhead 30 and the diameter D of the hammerhead disc 20 satisfy the following relationship: 15% ≤ L / D ≤ ​​20%. Furthermore, the diameter D of the hammerhead disc 20 is between 1500 mm and 2000 mm. Through the above configuration, the hammerhead 30 in this embodiment has a relatively larger size, thereby increasing the crushing and shaping efficiency.

[0049] The technical solution of this application features a more suitable shaping hammer, an optimized liner 40, and a narrower and more regular shaping spacing. This allows the material processing device in this embodiment to achieve both crushing and shaping effects on graphite particles, enabling the device to increase the tapped density to 0.65 g / cm³ with very few shaping passes. 3 above.

[0050] Furthermore, in this embodiment, there is only one hammerhead disc 20, and correspondingly, there is also only one accommodating cavity in the housing 10. This arrangement simplifies the equipment structure, reduces energy consumption, and increases the width of the accommodating cavity, thereby increasing the processing space of the material processing device.

[0051] like Figure 1 As shown, the material processing device also includes a feed inlet 60 and a discharge outlet 70. Graphite granules enter the receiving cavity through the feed inlet 60 and exit through the discharge outlet 70.

[0052] This application also provides a material processing machine, including the aforementioned material processing apparatus. Furthermore, the material processing machine further includes a weighing and feeding hopper, a main fan, a grading assembly, and a dust collector.

[0053] The processing procedure of the material processing machine in this application is as follows:

[0054] Start-up preparation: Before the graphite granules enter the equipment, start the blower and grading components to fill the shaping circulation path of the material processing machine with air.

[0055] 2. Material Path: Graphite granules are fed into the material processing machine through the weighing and feeding hopper. They are then carried by airflow through the pipeline to the classification chamber. Under the secondary washing action of the airflow in the classification chamber, the graphite granules begin to disperse into a vortex and rise to the vicinity of the classifier for classification. Fine powder passes through the classifier and is carried by the fan to the dust collector at the rear for storage. Particles with higher compaction density fall from the vacuum area in the middle of the classifier into the material processing device. The graphite granules are shaped within the material processing device, increasing their compaction density. During this process, new fine powder generated by the collisions of the material in the material processing device is also sucked out through the outlet passage at the other end and returned to the classification chamber for further classification. This achieves a cycle where fine powder circulates within the material processing machine, while coarse particles continue to be shaped within the material processing device, ultimately resulting in spherical graphite granules that meet the required specifications. After the system-set shaping time is completed, the airlock mechanism below the grading chamber will automatically shut off. The graphite particles in the material processing device will be drawn from the pipe below the feeding hopper to the conical funnel below the grading chamber for storage. The discharge valve will open, and the graphite particles will be released from the conical funnel, thus ending the entire shaping process.

[0056] The processing area of ​​the material processing device is in a circular accommodating cavity. During the flow of graphite particles, the rotating hammer disk 20 provides a reverse flow force to the graphite particles. This force is opposite to the flow direction of the graphite particles, confining the graphite particles in the material processing device and preventing large particles from entering the upper grading zone for classification. Large particles will repeatedly fall into the material processing device and be crushed and shaped in the material processing device.

[0057] In this process, after the graphite particles enter the material processing device, they are drawn and rotated by the hammer 30 within the device's accommodating cavity. This results in compression, friction, shearing, and collision between the particles and between the particles and the hammer 30, liner 40, and third grinding column 50. During this process, the flake graphite is broken down and compressed. Large particles gradually take on a potato-like shape after multiple collisions, while smaller particles, due to their lower collision intensity, cannot combine with the larger particles and are separated by the equipment, becoming the tailings. Throughout this process, large particles repeatedly undergo the main machine shaping → grading and screening → main machine shaping → grading and screening process, continuously being shaped and impacted to achieve the required tap density and specific surface area. The resulting finished product exhibits superior recyclability compared to conventional products.

[0058] The following are examples and comparative examples of materials processed by the material processing machine of this application.

[0059] Example 1

[0060] After being crushed, petroleum coke is obtained as a material with a particle size of 9-10μm (D50). The crushing equipment then enters the shaping equipment through a negative pressure conveying system.

[0061] In the material processing device, the material is subjected to impact from hammer 30, compression between hammer 30 and the third grinding column 50, and vortex generation between the material and the liner 40 for grinding, thereby increasing the material's compaction density and optimizing its specific surface area. During this process, new fine powder generated by the force and collision of the material in the material processing device is also sucked out through the outlet passage at the other end and returned to the classification chamber for reclassification. This achieves the circulation of fine powder in the equipment and the continuous shaping of coarse particles in the material processing device, ultimately modifying it into a shaped product that meets the requirements. After the shaping time set by the system ends, the compaction density of raw coke particles with D50 = 10-11μm can be increased to ≥0.65g / cm³ after shaping. 3 The specific surface area can be optimized to ≤1.0m². 2 / g.

[0062] After subsequent processes such as graphitization, the tap density of the product is increased to ≥1.4 g / cm³. 3 The specific surface area is reduced to ≤0.7m². 2 / g, magnetic substances and trace elements are normal, and the specific data are shown in Tables 1 to 3 below.

[0063] Comparative Example 1

[0064] After being crushed, shaped and classified by traditional process equipment such as airflow vortex pulverizers (e.g., QW30, LCR1000, etc.), raw coke is obtained as a material with a particle size of 9-10μm and a D50.

[0065] In the traditional crushing and shaping process, materials are subjected to the impact force of hammers and the collision between materials, which increases the material's compacted density and optimizes its specific surface area. Continuous crushing and shaping can increase the compacted density of particles with a D50 of 15-25μm to ≥0.5g / cm³. 3 The specific surface area is processed to <2.0m². 2 / g.

[0066] After undergoing graphitization and other subsequent processes, the finished product has particles with a D50 of 10-11 μm and a tap density increased to ≥1.0 g / cm³. 3 The specific surface area is reduced to ≤4m². 2 / g, magnetic substances and trace elements are normal, and the specific data are shown in Tables 1 to 3 below.

[0073] As can be seen from Tables 1 to 3, all performance indicators of the finished product in Comparative Example 1 are normal, while the performance indicators of the finished product in Example 1 are also normal, with better capacity and cycle performance. Therefore, the material processing machine of this application has excellent material processing performance.

[0074] Example 2

[0075] After being crushed, petroleum coke is obtained as a material with a particle size of 7-8μm (D50). The material is then fed into the shaping equipment via a negative pressure conveying system from the crushing equipment.

[0076] In the material processing device, the material is subjected to impact from hammer 30, compression between hammer 30 and the third grinding column 50, and vortex generation between the material and the liner 40 for grinding, thereby increasing the material's compaction density and optimizing its specific surface area. During this process, new fine powder generated by the force and collision of the material in the material processing device is also sucked out through the outlet passage at the other end and returned to the classification chamber for reclassification. This achieves the circulation of fine powder in the equipment and the continuous shaping of coarse particles in the material processing device, ultimately modifying it into a shaped product that meets the requirements. After the shaping time set by the system ends, the compaction density of raw coke particles with D50 = 8-9μm can be increased to ≥0.6g / cm³ after shaping. 3The specific surface area can be optimized to ≤1.2m². 2 / g.

[0077] After subsequent processes such as graphitization, the tap density of the product is increased to ≥1.6 g / cm³. 3 The specific surface area is reduced to ≤0.9m². 2 / g, magnetic substances and trace elements are normal, and the specific data are shown in Tables 4 to 6 below.

[0078] Comparative Example 2

[0079] After being crushed, shaped and classified by traditional process equipment such as airflow vortex pulverizers (e.g., QW30, LCR1000, etc.), raw coke is obtained as a material with a particle size of 7-8μm and a D50.

[0080] In the traditional crushing and shaping process, materials are subjected to the impact force of hammers and the collision between materials, resulting in an increase in compacted density and optimization of specific surface area. Continuous crushing and shaping can increase the compacted density of particles with a D50 of 8-9 μm to ≥0.48 g / cm³. 3 The specific surface area is processed to <2.2m². 2 / g.

[0081] After graphitization, the finished product has a tap density of ≥1.4 g / cm³ for particles with a D50 of 8-9 μm. 3 The specific surface area is reduced to ≤4.3m². 2 / g, magnetic substances and trace elements are normal, and the specific data are shown in Tables 4 to 6 below.

[0088] As can be seen from Tables 4 to 6, all performance indicators of the finished product in Comparative Example 2 are normal, while the performance indicators of the finished product in Example 2 are also normal, with better capacity and cycle performance. Therefore, it is evident that the material processing machine of this application has excellent material processing capabilities.

[0089] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The material processing device includes a housing 10, a hammer head disk 20, and hammer heads 30. The housing 10 has a receiving cavity, the hammer head disk 20 is rotatably disposed in the receiving cavity, and there are multiple hammer heads 30. The multiple hammer heads 30 are arranged at intervals along the circumference of the hammer head disk 20 on the axial end face of the hammer head disk 20, and the length direction of the hammer head 30 is parallel to the radial direction through the center of the axial end face. The hammer head 30 includes a first working part 31 and a second working part 32 connected in sequence. The top end of the first working part 31 is arc-shaped, and the first working part... The width of the first working part 31 is greater than the width of the second working part 32. The first working part 31 protrudes from the outer periphery of the hammer head disk 20. By setting a rotatable hammer head 30 in the accommodating cavity, and the first working part 31 protruding from the outer periphery of the hammer head disk 20 has an arc-shaped top and a large width, the direction of the granular material after colliding with the hammer head 30 can be increased. This increases the chances of extrusion, friction, and collision between granular materials and between granular materials and the inner wall of the housing 10 after the granular material enters the accommodating cavity, thereby improving the processing efficiency and effect of the granular material.
