Description

Technical Field

[0001] This utility model relates to the field of graphite particle separation technology, specifically to a device for refining and separating spherical graphite particles. Background Technology

[0002] Spherical graphite, as a core raw material for lithium-ion battery anode materials, has been widely used in new energy, energy storage and other fields due to its excellent conductivity, high crystallinity and good charge and discharge performance. In the production and processing of spherical graphite, particle refinement and separation is a crucial step, and its separation effect directly affects the quality and performance of the final product. Existing separation devices lack effective impurity removal structures. Spherical graphite raw materials often contain light impurities such as dust and debris, resulting in a large amount of impurities remaining in the separated graphite particles, affecting the quality of subsequent processing. The screens of existing separation devices are prone to particle accumulation after long-term use, requiring frequent manual cleaning. This not only increases the labor intensity of operators but also leads to a decrease in screening efficiency due to untimely cleaning. Some separation devices have complex structural designs, making screen disassembly and assembly inconvenient and maintenance difficult. Furthermore, particles are prone to clogging the discharge channel during the separation process, further reducing production efficiency. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 6 This embodiment of a spherical graphite particle refining and separation device includes a housing 1. Two sets of grooves 3 extending into the interior are formed on the surface of the housing 1. A screen 2 is slidably connected in each groove 3. A first discharge chute 4 is located below the housing 1. A removal pipe 6 is connected to the bottom of the first discharge chute 4. A removable filter screen 5 is located above the removal pipe 6. A removal chamber 7 is connected below the removal pipe 6. A fan 8 is installed on the side of the removal chamber 7. A chamber door 9 is installed on the surface of the removal chamber 7. The removal process involves the fan 8... Continuous operation creates a negative pressure environment within the impurity removal chamber 7, effectively adsorbing and collecting lightweight impurities such as dust and debris that fall with the material, ensuring the purity of the spherical graphite particles and improving the overall quality of the product. The slidingly connected screen 2 not only facilitates quick disassembly and specification adjustment but also improves screening efficiency and flexibility. The first discharge chute 4 and the detachable filter screen 5 enable centralized discharge and secondary filtration of fine particles after screening. The chamber door 9 facilitates regular cleaning of impurities inside the chamber 7, maintaining the continuous and efficient operation of the impurity removal system.

[0018] The housing 1 has two cavities inside, each with a telescopic rod 12. The other end of each telescopic rod 12 is connected to a slider 13. The sides of the two sliders 13 are connected to a long rod 17, and the surface of the long rod 17 is connected to a scraper 18. Driven by the telescopic rod 12, the slider 13 drives the long rod 17 and the scraper 18 on its surface to move along the inner wall of the housing 1, pushing the material flowing down to the top for repeated filtration. It can also scrape off graphite particles attached to the housing wall, avoiding the decrease in screening efficiency and cleaning problems caused by particle accumulation.

[0019] The second discharge chute 10 is provided on the side of the box 1 above the screen 2. The second discharge chute 10 is equipped with a sliding door 11. Graphite particles of different sizes can smoothly enter the corresponding collection channel, avoiding particle mixing and improving the accuracy of separation. The flexible opening and closing of the sliding door 11 ensures the effective discharge of materials.

[0020] A telescopic baffle 16 is installed between the first discharge chute 4 and the box body 1. The telescopic baffle 16 enables flexible control of the opening and closing state of the first discharge chute 4. Two first guide plates 19 and a second guide plate 20 are installed inside the box body 1. The first guide plates 19 and the second guide plates 20 optimize the flow path of the material in the box body 1. They can not only guide the material to be evenly distributed on the screen 2 and improve the screening efficiency, but also effectively reduce the residence time of the material in the box body 1, avoid excessive friction and damage between particles, and ensure the integrity and quality of the spherical graphite particles.

[0021] The box 1 has a feed inlet 14 on the top, a cover plate 15 on the top of the feed inlet 14, and a handle 23 on the top of the cover plate 15. The handle 23 makes it easy to open or close the feed inlet 14 for material feeding and management. The cover plate 15 effectively prevents dust, debris and other impurities generated during the screening process from overflowing, maintaining a clean and safe working environment.

[0022] The bottom of the housing 1 is connected to four support legs 21, and the bottom of each support leg 21 is connected to a base 22. This structural design not only enhances the stability of the device, but also ensures the smooth operation of the device during the working process. The combination of the support legs 21 and the base 22 effectively disperses the pressure of the device on the ground, prevents problems such as ground subsidence or device tilting caused by long-term operation, and further extends the service life of the device.

[0023] The working principle of the above embodiment is as follows: In use, spherical graphite particles are poured into the box 1 through the feed port 14. The material is graded and screened by two sets of screens 2. Larger particles are intercepted by the upper screen 2, while fine particles fall to the bottom of the box 1 through the screen 2. By adjusting the opening degree of the telescopic baffle 16, the amount of fine particles discharged from the first discharge chute 4 can be controlled. The airflow generated by the blower 8 passes through the filter screen 5 and the impurity removal pipe 6, and draws light impurities such as dust and debris in the material into the impurity removal chamber 7 for collection, thereby achieving effective separation of impurities. The impurities in the impurity removal chamber can be cleaned by opening the chamber door 9. The telescopic movement of the telescopic rod 12 drives the slider 13 and the connected long rod 17 and scraper 18 to move. The scraper 18 can scrape along the inner wall of the box 1, pushing the material flowing down to the top for repeated filtration. It can also clean the residual material attached to the inner wall of the box 1, ensuring the cleanliness and efficient operation of the device.

[0024] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
