Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery manufacturing, and more specifically, to a dispersed transfer tank. Background Art

[0002] As the mainstream energy storage technology today, the development of lithium batteries has always received great attention from scientific researchers and engineers around the world. From portable electronic devices to electric vehicles, from wearable devices to energy storage systems, the widespread application of lithium batteries has greatly changed our lifestyle. However, despite significant progress, there are still many technical problems that need to be solved in the face of the actual needs of battery performance improvement and application development. Among them, the optimization and improvement of battery slurry preparation process is considered to be a key way to improve the performance of lithium batteries and reduce production costs. Battery slurry preparation involves multiple links, including mixing, grinding, stirring, coating and drying. In these links, the role of slurry transfer tank is crucial. The slurry transfer tank not only serves as a transfer station for stirring and coating, but also needs to maintain the stability of the slurry's physical properties such as viscosity, solid content and temperature for a long time. This is because these physical properties directly affect the fluidity and uniformity of the slurry during coating and drying, and then affect the morphology and performance of the electrode sheet. Therefore, how to design and select a transfer tank that can effectively ensure the stability of the slurry's physical properties is crucial.

[0003] However, most of the existing slurry transfer tanks use a single spiral structure of stirring paddle blades. This design can complete the stirring task to a certain extent, but there are some obvious problems. Due to its single stirring form, it is difficult to ensure the stability of the slurry stirring and dispersion, especially when a large amount of slurry in a single batch is pumped into the transfer tank and stirred for a long time without output, slurry precipitation is likely to occur, causing the viscosity and solid content of the slurry in the tank to gradually increase. Once this problem occurs, it may cause dimensional deviations in the subsequent coating process, thereby affecting the quality of the lithium battery. In addition, due to the limitations of the design and structure of the traditional stirring method, it often takes a lot of time for the slurry to reach the expected stirring and dispersion state, which not only leads to low slurry processing efficiency, but also may cause changes in the slurry properties, affecting the quality of the final product.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0022] Reference Figures 1 to 3As shown, the utility model discloses a dispersion transfer tank. Specifically, the device includes a stirring paddle assembly 10, a dispersion assembly 20 and a barrel body 30;

[0023] The barrel body 30 is provided with a barrel cover 301, and the stirring paddle assembly 10 includes a first motor 101, a reducer 102, a first bearing seat 103, a first coupling 104, and an anchor stirring paddle 105. The output end of the first motor 101 is connected to the reducer 102, and the two ends of the first bearing seat 103 are respectively connected to the reducer 102 and the barrel cover 301. The first coupling 104 is arranged inside the first bearing seat 103, and the two ends of the first coupling 104 are respectively connected to the output end of the reducer and the anchor stirring paddle 105; The component 20 includes a second motor 201, a second bearing seat 202, a second coupling 203 and a dispersion shaft 204. The two ends of the second bearing seat 202 are respectively connected to the second motor 201 and the barrel cover 301. The second coupling 203 is arranged inside the second bearing seat 202. The two ends of the second coupling 203 are respectively connected to the output end of the second motor 201 and the dispersion shaft 204. The dispersion shaft 204 is arranged on the inner side of the blade 106 of the anchor-type stirring paddle 105, and a plurality of dispersion disks 205 are arranged on the dispersion shaft 204, which can rotate to disperse the slurry. This dispersion transfer tank device combines the stirring and dispersing functions. A dispersion shaft 204 is added on the basis of the anchor-type stirring paddle 105. Different from the previous spiral stirring paddle structure, the dispersion disk 205 can make the slurry produce a small vortex, and the slurry particles are quickly diffused during the high-speed rotation of the dispersion disk 205. This design provides effective stirring and dispersing functions, which helps to improve the processing efficiency and quality of the slurry. Two sets of dispersion components 20 are placed on different axes in the dispersion transfer tank, and two sets of stirring motors are used to drive the motor speed and monitor the temperature in the tank according to the viscosity, solid content and other characteristics of the slurry, thereby improving the processing efficiency of the slurry and ensuring the quality requirements of slurry manufacturing. The reducer 102 is set to convert greater torque while reducing the rotation speed, so that the equipment can cope with greater loads and resistance. By reducing the speed of the motor through the reducer, the inertia of the motor load can be significantly reduced, thereby reducing the loss of the motor and improving the life and efficiency of the motor.

[0024] Furthermore, a plurality of dispersing teeth are arranged circumferentially on the edge of the dispersing disc 205, and part of the dispersing teeth is biased toward one side of the axial direction of the dispersing axis 204, and the remaining dispersing teeth are biased toward the other side of the axial direction of the dispersing axis 204. The dispersing teeth on the edge of the dispersing disc can generate strong stirring and shearing forces under high-speed rotation, so that the solid particles in the slurry are fully dispersed. The design of the teeth can increase the shearing force, so that the slurry can be mixed evenly in a shorter time. At the same time, since part of the dispersing teeth is biased toward one side of the axial direction and the other part is biased toward the other side of the axial direction, this arrangement can allow the slurry to generate vortices when it is dispersed, further enhancing the mixing degree of the slurry and improving the efficiency and quality of slurry preparation.

[0025] like Figure 3 As shown, the barrel body 30 is a double-layer structure, and there is a 65L cavity between the outer wall and the inner wall for storing cooling water. The dispersed transfer tank also includes a slurry feed port 40, a slurry discharge port 50, a cooling water inlet 60 and a cooling water outlet 70. The slurry feed port is installed on the barrel cover 301, and the slurry outlet passes through the inner and outer walls of the barrel body 30 and is arranged at the bottom of the barrel body 30. The cooling water inlet 60 is arranged at the bottom of the outer wall of the barrel body 30, and a cooling water circulation pipeline is also arranged at the cooling water inlet 60. The cooling water outlet is arranged on the side of the outer wall of the barrel body 30. One end of the temperature sensor 120 is installed on the barrel cover 301, and the other end is in the barrel body 30 to monitor the temperature of the slurry in the barrel in real time. First, the slurry is pumped into the slurry feed barrel from the slurry feed port 40. When the liquid level reaches the set height, the first motor 101 and the second motor 201 are used to drive and control the rotating anchor stirring paddle 105 and the dispersion shaft 204 respectively, and the rotation speed is adjusted to generate eddy flow direction. With continuous rotation, the slurry temperature rises. If the data monitored by the temperature sensor is greater than the set temperature upper limit parameter, it is fed back to the temperature control electrical module, and the cooling water circulation pipe at the bottom is automatically opened to inject the outer wall interlayer of the barrel from bottom to top, and the cooling water rises to the cooling water drain port 70 to discharge the cooling water, thereby achieving the effect of automatic cooling.

[0026] Further, see Figure 1As shown, the first bearing seat 103 is provided with a first positioning bearing 80 and a second positioning bearing 90, and the first positioning bearing 80 and the second positioning bearing 90 are sleeved on the anchor stirring paddle 105 to improve the concentricity of the anchor stirring paddle 105 and achieve better positioning. The second bearing seat 202 is provided with a third positioning bearing 100 and a fourth positioning bearing 110, and the third positioning bearing 100 and the fourth positioning bearing 110 are sleeved on the dispersion shaft 204 to improve the concentricity of the dispersion shaft 204 and reduce rotational jump. The above-mentioned dual-bearing positioning can significantly improve the concentricity of the anchor stirring paddle 105 and the dispersion shaft 204, ensure the stability and accuracy of the equipment during rotation, and improve the precision of stirring and dispersion. The dual-bearing positioning is more stable, so that the anchor stirring paddle 105 and the dispersion shaft 204 are more stable during operation, avoiding the adverse effects caused by the axis deviation.

[0027] Further, refer to Figures 1 to 3 As shown, the dispersion transfer tank also includes a barrel bracket 130, the middle of which can accommodate the barrel tank body 30. The design of the barrel bracket 130 enables the barrel tank body 30 to use space efficiently and save space. The bottom of the barrel bracket 130 is provided with a caster 1301 with a foot cup. When in use, the foot cup can fix the equipment, increase the stability of the equipment, reduce the vibration generated during the slurry stirring process, and help reduce the generation of bubbles and improve the quality of the coating. When the barrel tank body 30 needs to be cleaned, it can be quickly switched to the caster, so that the equipment has good maneuverability, can be easily moved, and is easy to clean and maintain. The dispersion transfer tank also includes a control cabinet 170 and a weighing detector 108. The control cabinet 170 is arranged on the side of the barrel tank body 30. The three weighing detectors 108 are evenly distributed on the side of the barrel tank body 30. The control cabinet 170 is arranged on the side of the barrel tank body 30, which can conveniently and quickly control the operation of the equipment. During high-speed rotation, the slurry level in the barrel may fluctuate, resulting in inaccurate monitoring data from conventional contact or ultrasonic sensors. This configuration can provide continuous and real-time weight monitoring of the slurry, ensure its accuracy during the batching process, avoid over- or under-dosing, and ensure production quality. Three weighing detectors 108 are evenly distributed on the sides of the barrel body 30, which can accurately measure and monitor the weight of the slurry in the barrel body 30. The control cabinet 170 and the weighing detector 108, combined with precise digital display and convenient operation design, can provide a better working environment, reduce operating errors, and enhance employee job satisfaction.

[0028] The barrel cover 301 is provided with a pressure gauge 140 and a visual window 150. The pressure gauge 140 can display the vacuum pressure in the barrel. Through the visual window 150, the operator can directly observe the material status in the barrel body 30, avoiding the trouble of repeatedly opening and closing the equipment, and is also conducive to the immediate discovery and handling of problems that may occur during the operation of the dispersion transfer tank. Through the pressure gauge 140 and the visual window 150 on the barrel cover 301, basic monitoring and observation work can be completed in the same position, which avoids the trouble of the operator running back and forth around the equipment, improves work efficiency, and also reduces safety risks at work. During the high-speed rotation process of the paint stirring, the equipment often generates a certain amount of noise. The establishment of a muffler 160 can reduce these noises, create a better working environment for the staff, and reduce the noise impact on the surrounding environment. For this reason, a muffler 160 is also provided on the barrel cover 301.

[0029] The beneficial effects of the utility model are as follows: the device improves the processing efficiency and quality of the slurry and ensures the stability of the slurry manufacturing environment.

[0030] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
