Description
Technical Field
[0001] The utility model relates to the field of material crushing and processing, and specifically to a device for crushing a pitch hard carbon precursor. Background Art
[0002] In today's society, due to the booming electric vehicle industry, battery technology has been further developed in recent years. For example, rechargeable lithium batteries, also known as lithium-ion batteries, have been valued by major companies since their commercialization. At present, the backup energy of electric vehicles has gradually been replaced by lithium-ion batteries from traditional petroleum energy, but as lithium-ion batteries are more and more widely used in the market, the price of lithium is also getting higher and higher. Since sodium and lithium are elements in the same main group, there is also room for development in using sodium-ion batteries instead of lithium-ion batteries. Among them, sodium-ion batteries, as a highly anticipated new battery technology, have received much attention from researchers and the industry. Compared with traditional lithium-ion batteries, sodium-ion batteries have many potential advantages. First, as one of the abundant resources on the earth, sodium is more sustainable than scarce lithium resources, and its price is relatively stable, which is expected to bring greater stability and predictability to the battery industry. Secondly, sodium-ion batteries have more advantages in safety than lithium-ion batteries, and their lower cost and higher safety are expected to attract a wider market.
[0003] As one of the key elements affecting battery performance, hard carbon materials for the negative electrode of sodium-ion batteries have attracted much attention. Hard carbon materials have abundant resource sources and good cycle stability, making them suitable for use as negative electrode materials for sodium-ion batteries. Their excellent conductivity and stability make it possible to improve the performance of sodium-ion batteries. During the preparation process, the asphalt hard carbon precursor needs to be crushed before use. The crushing effect of the asphalt hard carbon precursor will directly affect the quality of the finished product of the sodium-ion battery. Therefore, it is necessary to develop a crushing device specifically for asphalt hard carbon precursors. Utility Model Content

[0025] First Exemplary Embodiment
[0026] Figure 1 A structural cross-sectional view of a pitch hard carbon precursor pulverizing device according to an exemplary embodiment is shown. Figure 1 The pitch hard carbon precursor pulverizing apparatus of this exemplary embodiment will be described.
[0027] In this exemplary embodiment, Figure 1As shown in , the asphalt hard carbon precursor crushing device mainly includes a housing 1, a graded crushing mechanism and a vibration mechanism 3. The graded crushing mechanism is arranged inside the housing 1. The vibration mechanism 3 is arranged on the outer wall of the housing 1. The graded crushing mechanism includes a large-diameter gear set 21 and a small-diameter gear set 22, and the large-diameter gear set 21 is arranged above the small-diameter gear set 22. When the asphalt hard carbon precursor is crushed, it is first crushed by the large-diameter gear set 21. The small-diameter gear set 22 performs secondary crushing on the asphalt hard carbon precursor crushed by the large-diameter gear set. In addition, multiple sets of gear sets can be added on this basis according to the crushing needs to complete the crushing work at one time, thereby improving the crushing efficiency and crushing effect. The diameter ratio of the large-diameter gear set to the small-diameter gear set can be 1:2. For example, the diameter of the large-diameter gear set can be 20 cm. Then the diameter of the small-diameter gear set can be 10 cm. By processing the asphalt material through two graded crushings, the obtained asphalt material has a smaller particle size and is more suitable for the preparation of sodium-ion batteries. In addition, the total length of the gears in the small diameter gear set can be equal to the length of the large diameter gear set, and the asphalt material crushed by the large diameter gear set can be transferred to the small diameter gear set for secondary crushing. The large diameter gear set and the small diameter gear set can be fixed side by side on the inner wall of the box.
[0028] In this exemplary embodiment, Figure 1 As shown in the figure, the large diameter gear set 21 and the small diameter gear set 22 can be horizontally distributed inside the housing 1. The large diameter gear set 21 and the small diameter gear set 22 can be arranged at a certain height. For example, the height can be set at a distance of 50 to 80 cm. The distance can reduce the friction between the gears and increase the service life of the gears.
[0029] In this exemplary embodiment, Figure 1 As shown in the figure, a plurality of first baffles 41 may be respectively arranged on the inner walls of both sides of the housing 1 above the large diameter gear set 21. The first baffle 41 is fixed on the inner wall of the housing 1 at an angle downward, so that the asphalt can slide smoothly down to the large diameter gear set 21 for crushing. A plurality of second baffles 42 may also be respectively arranged on the inner walls of both sides of the housing 1 between the large diameter gear set 21 and the small diameter gear set 22. The second baffle 42 is also fixed on the inner wall of the housing 1 at an angle downward, so that the asphalt passing through can slide smoothly down to the small diameter gear set 22 for crushing again. The angle between the lower side of the first baffle and the second baffle and the housing may be 60° to 80°, such as 71°, 74° or 79°. The angle between the upper side of the first baffle and the second baffle and the housing may be 100° to 120°, such as 101°, 106° or 109°.
[0030] In this exemplary embodiment, Figure 1As shown in , the bottom of the box body 1 may be provided with a plurality of support rods 11. For example, 2, 3, or 4. The support rods 11 can provide support for the entire device to prevent the device from collapsing.
[0031] In this exemplary embodiment, Figure 1 As shown in the figure, a feed port 12 may be provided at the top of the box 1, and a discharge port 13 may be provided at the bottom of the box 1. The feed port 12 is connected to the grading crushing mechanism. After the asphalt to be crushed is put into the feed port 12, it can be directly dropped by the baffle into the grading crushing mechanism for crushing. After the grading crushing mechanism crushes the asphalt, the asphalt falls through the discharge port 13. The crushed asphalt can be directly collected at the discharge port 13. The process is simple and convenient with a high degree of automation.
[0032] In this exemplary embodiment, both the grading and crushing mechanism and the vibration mechanism are connected to an external power source via a switch, and the operating states of the vibration mechanism and the grading and crushing mechanism can be controlled by the switch.
[0033] In this exemplary embodiment, the vibration mechanism can vibrate the asphalt adhering to the inner wall of the box, and then the asphalt is crushed by the classification crushing mechanism. The vibration amplitude of the vibration mechanism can be 50 to 60 Hz. For example, 53 Hz, 57 Hz or 59 Hz. Figure 1 As shown in , the vibration mechanism 3 can be fixedly arranged on both sides of the outer wall of the box body.
[0034] The crushing process of the asphalt hard carbon precursor crushing device of the utility model may include: firstly, the hard carbon precursor is placed in the feed port, and then the material slides through the baffle to the large diameter gear crushing group, the large diameter gear crushing group first crushes the larger asphalt for the first time, and then the crushed asphalt falls through the baffle to the small diameter gear crushing group, and then the small diameter gear crushing group crushes the asphalt again to make the particle size of the asphalt particles smaller. Finally, the crushed asphalt is collected at the discharge port. If the particle size of the crushed asphalt is too large, a new round of crushing process can be carried out again until the particle size that meets the requirements is obtained. In addition, if the asphalt material adhered to the inner wall of the box is cleaned, the vibration device can be started to vibrate the entire device to make the asphalt material adhered to the inner wall of the device fall off, and then the device is started again to crush the fallen asphalt to achieve material reuse.
[0035] In summary, the advantages of the present invention may include at least one of the following:
[0036] (1) The crushing device provided by the utility model has a long service life, the cleaning process after crushing the asphalt is convenient and efficient, and the crushing efficiency is high.
[0037] (2) The pulverizing device provided by the utility model has excellent pulverizing effect and can effectively ensure the product quality of sodium ion batteries;
