Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery material processing technology, and in particular to a wet ball milling and dispersion device for silicon-carbon anode materials. Background Technology

[0002] In the production and processing of silicon-carbon anode materials, wet ball milling dispersion is one of the key steps. Its purpose is to refine and uniformly disperse the silicon-carbon anode material particles to ensure the performance of subsequent products.

[0003] However, in existing technologies, the intense collisions and friction between materials and between materials and grinding balls during ball milling generate a large amount of heat. If this heat cannot be dissipated effectively and in a timely manner, it can affect the material properties and even lead to deterioration. Furthermore, in traditional ball mill dispersion devices, the cooling structure is often fixed in position, making it difficult to adjust flexibly according to the working state of the ball mill. This results in limited cooling effectiveness. The traditional cooling method is relatively simple and has low heat exchange efficiency, making it difficult to meet the stringent temperature control requirements of silicon-carbon anode materials. In addition, the adjustment of the cooling structure is not convenient or precise enough, resulting in poor adaptability and affecting the quality and efficiency of ball mill dispersion. The driving stability of the ball mill and the overall operational flexibility of the device also suffer from shortcomings. Utility Model Content

[0004] This invention provides a wet ball milling and dispersion device for silicon-carbon anode materials that facilitates improved cooling efficiency, ball milling quality, and operational flexibility.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wet ball milling and dispersion device for silicon-carbon anode materials, comprising a base plate, with positioning seats fixedly installed on the upper surfaces of both ends of the base plate, and a ball mill body rotatably installed between the two positioning seats. A cooling mechanism is fixedly installed on the upper surface of the base plate, and the cooling mechanism is symmetrically distributed on both sides of the ball mill body. The cooling mechanism includes a housing, one end of which is connected to a water inlet pipe, and the other end of which is connected to a water outlet pipe. An air-gathering groove is provided on the inner side wall of the housing, and exhaust components are provided on both sides of the housing. A fan is fixedly installed on the inner side of the exhaust component. The exhaust components are located on both sides of the air-gathering groove. The water inlet pipe introduces cooling medium into the housing, and the water outlet pipe discharges the used cooling medium. At the same time, the fans fixedly installed on the inner side of the exhaust components on both sides of the housing operate, cooperating with the air-gathering groove on the inner side wall, so that the airflow converges at the air-gathering groove and flows through the exhaust components, thereby enhancing the heat exchange efficiency between the cooling medium and the ball mill body.

[0006] Preferably, a geared motor is fixedly installed on one side of one of the positioning seats, and the output end of the geared motor is fixedly connected to the rotating shaft of the ball mill body, so that the geared motor provides stable power output to the ball mill body.

[0007] Preferably, a positioning base is fixedly installed on the upper surface of the middle section of the base plate, and an electric cylinder is rotatably connected to the top of the positioning base. The rotatable connection between the electric cylinder and the positioning base gives the electric cylinder the flexibility to adjust its angle, which can adapt to different working requirements and facilitate its better cooperation with other components of the device.

[0008] Preferably, an extension plate is fixedly installed on one side of the housing, and the extension plate is rotatably connected to the piston rod of the electric cylinder. The rotatable connection between the extension plate and the piston rod of the electric cylinder provides room for adjustment. As a connecting component, the extension plate realizes an effective connection between the housing and the electric cylinder.

[0009] Preferably, a sector gear is fixedly installed at the end of each of the two housing shells. The two sector gears mesh with each other. When one housing shell rotates under the drive of the electric cylinder through the extension plate, the sector gear at its end will drive the sector gear at the end of the other housing shell that meshes with it to rotate synchronously, thereby driving the other housing shell to rotate accordingly. The meshing connection of the two sector gears realizes the linkage of the two housing shells, ensuring that the two move in a coordinated manner during the adjustment process.

[0010] Preferably, the sector gear is rotatably connected to the base plate, and the housing is rotated around the sector gear as the center under the push of the electric cylinder to adjust its own angle. The rotation around the sector gear as the center makes the angle adjustment of the housing more controllable and can be precisely adjusted to a position that matches the ball mill body, thereby enhancing the cooling effect of the cooling mechanism.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, efficient cooling is achieved through the multiple cooling design of the cooling mechanism. The housing forms a cooling medium circulation through the water inlet and outlet pipes. At the same time, the fan in the exhaust component works with the air concentrator to enhance airflow and greatly improve heat exchange efficiency. This can effectively prevent the silicon-carbon anode material from being damaged by high temperature during ball milling. Compared with the traditional single cooling method, it can better guarantee material performance and ball milling quality.

[0013] 2. In this utility model, the synchronous angle adjustment of the two housing shells is achieved by means of the linkage structure of electric cylinder, extension plate and sector gear. The sector gear as the rotation center ensures that the adjustment is accurate and controllable. The cooling position can be flexibly adapted according to the working state of the ball mill body. The stable support of the positioning base for the electric cylinder and the rotation connection design of each component improve the flexibility and reliability of the device operation and solve the problems of fixed position and poor adaptability of traditional cooling structure.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a wet ball milling and dispersion device for silicon-carbon anode materials, including a base plate 1, with positioning seats 2 fixedly installed on the upper surfaces of both ends of the base plate 1, and a ball mill body 4 rotatably installed between the two positioning seats 2. A cooling mechanism 5 is fixedly installed on the upper surface of the base plate 1, and the cooling mechanism 5 is symmetrically distributed on both sides of the ball mill body 4. The cooling mechanism 5 includes a housing 51, one end of which is connected to a water inlet pipe 53, and the other end of which is connected to a water outlet pipe 54. An air-gathering groove 59 is formed on the inner side wall of the housing 51, and an exhaust assembly 58 is formed on both sides of the housing 51. A fan is fixedly installed on the inner side of the exhaust assembly 58, and the exhaust assembly 58 is located on both sides of the air-gathering groove 59. The base plate 1 provides the mounting foundation, and the positioning seats 2 on the upper surfaces of both ends are used to rotatably install the ball mill body 4, so that the ball mill body 4 can rotate to realize the wet ball milling and dispersion operation; the cooling mechanism 5 is fixedly installed on the upper surface of the base plate 1 and symmetrically distributed on both sides of the ball mill body 4. The cooling mechanism 5 utilizes a housing 51 to provide installation space for the cooling structure. A water inlet pipe 53 introduces cooling medium into the housing 51, while an outlet pipe 54 discharges the used cooling medium. Simultaneously, fans fixedly installed inside the exhaust components 58 on both sides of the housing 51 operate, working in conjunction with the air-gathering grooves 59 on the inner wall. This causes airflow to converge at the air-gathering grooves 59 and flow through the exhaust components 58, enhancing the heat exchange efficiency between the cooling medium and the ball mill body 4. The positioning seat 2 ensures stable rotation and installation of the ball mill body 4, guaranteeing the smooth operation of the wet ball milling dispersion process. The cooling mechanism 5, symmetrically distributed on both sides of the ball mill body 4, forms a cooling medium circulation system through the housing 51, water inlet pipe 53, and outlet pipe 54. Combined with the airflow enhancement structure formed by the exhaust components 58 with fans and the air-gathering grooves 59, it effectively cools the ball mill body 4, preventing excessively high temperatures from affecting the performance of the silicon-carbon anode material during ball milling and improving the quality and efficiency of ball milling dispersion.

[0022] according to Figure 1 As shown, a geared motor 3 is fixedly installed on one side of one of the positioning seats 2. The output end of the geared motor 3 is fixedly connected to the rotating shaft of the ball mill body 4. When the geared motor 3 fixedly installed on one side of one of the positioning seats 2 is working, its output end drives the rotating shaft of the ball mill body 4 fixedly connected to it to rotate, thereby driving the ball mill body 4 to rotate between the two positioning seats 2, realizing the wet ball milling and dispersion operation of silicon-carbon anode material. The geared motor 3 provides stable power output to the ball mill body 4, and the rotation speed of the ball mill body 4 can be adjusted through the deceleration effect, so that the ball mill body 4 can ball mill at a suitable speed, ensuring the effect and efficiency of wet ball milling and dispersion of silicon-carbon anode material. The positioning seat 2 provides installation support for the geared motor 3, ensuring its stable connection with the rotating shaft of the ball mill body 4, and ensuring the reliability of the entire driving process.

[0023] according to Figure 1 As shown, a positioning base 52 is fixedly installed on the upper surface of the middle section of the base plate 1. An electric cylinder 55 is rotatably connected to the top of the positioning base 52. The positioning base 52 fixedly installed on the upper surface of the middle section of the base plate 1 provides an installation base for the electric cylinder 55. The bottom of the electric cylinder 55 is rotatably connected to the top of the positioning base 52, so that the electric cylinder 55 can be rotated and adjusted around the positioning base 52. The positioning base 52 can stably support the electric cylinder 55 and ensure the stability of the electric cylinder 55 installation. The rotatable connection between the electric cylinder 55 and the positioning base 52 gives the electric cylinder 55 the flexibility of angle adjustment, which can adapt to different working requirements and facilitate its better cooperation with other components of the device, thereby improving the overall adaptability and practicality of the device.

[0024] according to Figure 2 and Figure 3 As shown, an extension plate 56 is fixedly installed on one side of the housing 51. The extension plate 56 is rotatably connected to the piston rod of the electric cylinder 55. When the electric cylinder 55 is working, the extension plate 56 fixedly installed on one side of the housing 51 of the cooling mechanism 5 is rotatably connected to the piston rod of the electric cylinder 55. When the electric cylinder 55 is working, the extension and retraction of its piston rod will drive the housing 51 to make corresponding position or angle adjustments through the extension plate 56. The rotatable connection between the extension plate 56 and the piston rod of the electric cylinder 55 provides room for such adjustment. As a connecting component, the extension plate 56 realizes the effective connection between the housing 51 and the electric cylinder 55, so that the electric cylinder 55 can smoothly drive the housing 51. The rotatable connection ensures the flexibility of the housing 51 during the adjustment process and avoids jamming or damage caused by rigid connection between components. At the same time, the adjustability of the position or angle of the housing 51 allows it to better fit the ball mill body 4, enhance the cooling effect, and improve the working efficiency and reliability of the device.

[0025] according to Figure 3 As shown, sector gears 57 are fixedly installed at the ends of both housings 51. The two sector gears 57 mesh with each other. When one housing 51 rotates under the drive of the electric cylinder 55 through the extension plate 56, the sector gear 57 at its end will drive the sector gear 57 at the end of the other housing 51 that meshes with it to rotate synchronously, thereby driving the other housing 51 to rotate accordingly. The meshing connection of the two sector gears 57 realizes the linkage of the two housings 51, ensuring that the two move in a coordinated manner during the adjustment process, and can move closer or further away from the ball mill body 4 at the same time, ensuring the uniformity and stability of cooling of the ball mill body 4, avoiding the impact of improper position of a single housing 51 on the cooling effect, and improving the overall working performance of the device.

[0026] according to Figure 3As shown, the sector gear 57 is rotatably connected to the base plate 1. Under the push of the electric cylinder 55, the housing 51 rotates around the sector gear 57 to adjust its angle. The sector gear 57 and the base plate 1 provide a pivot point for the rotation of the housing 51. When the electric cylinder 55 is working, its piston rod pushes the housing 51 through the extension plate 56, causing the housing 51 to rotate around the sector gear 57, thereby adjusting its angle. The rotatable connection between the sector gear 57 and the base plate 1 ensures the stability and accuracy of the housing 51 during rotation. The rotation method around the sector gear 57 makes the angle adjustment of the housing 51 more controllable, and can be precisely adjusted to a position that matches the ball mill body 4, enhancing the cooling effect of the cooling mechanism 5. At the same time, the push of the electric cylinder 55 provides stable power for angle adjustment, improving the convenience and flexibility of the device operation.

[0027] The operating method and working principle of this device are as follows: Upon startup, the position of the cooling mechanism 5 is first adjusted using the electric cylinder 55. The electric cylinder 55 rotates around the positioning base 52, and its piston rod drives one of the housing shells 51 to rotate around the sector gear 57 via the extension plate 56. Because the two sector gears 57 mesh, the other housing shell 51 rotates synchronously, adjusting the two housing shells 51 to a suitable angle to fit the ball mill body 4. Next, cooling medium is introduced into the housing shell 51 through the water inlet pipe 53. Simultaneously, the fan inside the exhaust assembly 58 is started, and the airflow converges through the air collection groove 59. The cooling medium is discharged through the outlet pipe 54 after it is used. Then, the geared motor 3 is started, and its output end drives the ball mill body 4 to rotate between the positioning seats 2 to carry out wet ball milling and dispersion of silicon-carbon anode materials. During the ball milling process, the cooling mechanism 5 works continuously. The electric cylinder 55 can adjust the angle of the housing 51 as needed to ensure the cooling effect. After the ball milling is completed, the geared motor 3 is turned off first. After the ball mill body 4 stops rotating, the cooling medium supply and the fan are turned off. Then, the electric cylinder 55 drives the housing 51 to reset. Finally, the processed material is taken out.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
