Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery production, and in particular to a lead-acid battery slurry stirring vessel. Background Technology
[0002] With the continuous development of lead-acid battery technology, the quality requirements for lead-acid battery slurry are becoming increasingly stringent. In the production process of lead-acid batteries, the uniformity and stability of the battery slurry are crucial. Battery slurry stirring equipment needs to ensure that various raw materials, such as positive and negative electrode active materials, conductive agents, and binders, are uniformly dispersed in the slurry, without localized areas of excessively high or low concentrations. The proportions of various components should remain consistent within every minute area to ensure stable performance of each part during subsequent battery manufacturing. Furthermore, solid particles such as active materials must be uniformly suspended in the slurry, preventing sedimentation or agglomeration. The size and distribution of particles should be as uniform as possible to avoid large particle aggregation or small particle sedimentation, ensuring battery consistency and performance stability. However, existing crushing devices still have some shortcomings in the cosmetics production field. For example, patent CN205965663U discloses a planetary stirring system, which has the following shortcomings in the stirring field: although the dead zone is small during stirring as a dual planetary stirring mechanism, it is difficult to disperse agglomerated materials during stirring, resulting in insufficient uniformity of the stirred slurry. Utility Model Content

Furthermore, through the stirring motion of the three planetary mixers, the batteries can be further uniformly integrated, greatly reducing the stirring dead zone of the stirring blades during the stirring process. This enables efficient, uniform, and stable stirring of the battery slurry, ensuring that the battery slurry achieves the required uniformity and stability.

Detailed Implementation
[0023] The following will refer to the appendix in the example of this utility model. Figure 1 - Appendix Figure 5 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] like Figure 1 As shown, this utility model provides a technical solution: a lead-acid battery slurry mixing vessel, including a frame 1, a motor 2 fixed to the upper end of the frame 1, a stirring mechanism 3 fixed to the lower end of the motor 2, and a hydraulic mechanism 4 fixed to the lower end of the stirring mechanism 3; the frame 1 provides stable support for the motor 2, the stirring mechanism 3, and the hydraulic mechanism 4, ensuring that the entire mixing vessel remains stable during operation, ensuring that each component is firmly installed, and preventing the stirring effect and safety from being affected by equipment shaking; the motor 2 provides power to the stirring mechanism 3, driving the transmission shaft in the stirring mechanism 3 to rotate, ensuring that the stirring mechanism 3 can operate at a sufficient speed to achieve efficient stirring of the battery slurry; the stirring mechanism 3 is mainly used to break up agglomerated substances in the battery slurry and to stir different substances evenly; the hydraulic mechanism 4 is used to lift the container 310, facilitating the disassembly and transportation of the container 310.
[0025] like Figure 2As shown, the stirring mechanism 3 includes an upper shell 301, a support frame 302 fixed to the upper end of the upper shell 301, a drive shaft 303 fixed to the center of the upper shell 301, a sun gear 304 fixed to the lower end of the drive shaft 303, planet gears 305 meshing with the outer side of the sun gear 304, a planetary support 306 meshing with the outer side of the planet gears 305, a rotating disk 307 fixed to the lower end of the planet gears 305, a fixing frame 308 fixed to the lower end of the rotating disk 307, a stirring wheel 309 fixed to the lower end of the fixing frame 308, and a container 310 installed at the lower end of the stirring wheel 309. The upper shell 301 protects the internal components of the stirring mechanism 3, prevents external impurities from entering, and also plays a certain role in sound insulation and heat insulation, ensuring that the internal environment of the stirring mechanism 3 is relatively stable and reducing the interference of external factors on the stirring process. The support frame 302 fixes the upper shell 301 and provides support for the connection between the frame 1 and the stirring mechanism 3. To ensure a secure connection between motor 2 and stirring mechanism 3, the power of the motor is stably transmitted to stirring mechanism 3. Drive shaft 303 transmits the power of motor 2 to sun gear 304, driving the entire stirring mechanism 3 to operate, thus achieving power transmission and enabling the stirring mechanism to function normally. Sun gear 304, acting as the central gear, meshes with planetary gears 305, driving planetary gears 305 to rotate. Through the cooperation with planetary gears 305, multi-planetary stirring motion is achieved, reducing dead zones and making the battery slurry more uniformly stirred. Planetary gears 305 rotate around sun gear 304, simultaneously driving rotating disk 307, fixed frame 308, and stirring wheel 309 to rotate. This planetary motion increases the complexity and uniformity of stirring, improving the stirring effect. Planetary support 306 supports planetary gears 305, ensuring their stable rotation around sun gear 304 and guaranteeing the stability of the planetary gears' trajectory during the stirring process. For reliability, the rotating disk 307 causes the stirring wheel 309 to move around the sun gear 304. The fixing frame 308 fixes the stirring wheel 309 to keep it stable during the stirring process, ensuring that the position of the stirring wheel 309 is fixed and preventing it from shaking or shifting, thus ensuring the stirring effect. The stirring wheel 309 directly stirs the battery slurry, breaking up agglomerated materials and making the battery slurry more uniformly fused. Through a special structural design, the cooperation of the stator 3091 and the rotor 3092 achieves efficient and uniform stirring, reduces material agglomeration, and improves the quality of the battery slurry. The container 310 holds the battery slurry and provides space for the stirring process.
[0026] like Figure 3 As shown, the stirring wheel 309 includes a stator 3091 fixed to the lower end of the rotating disk 307 and a rotor 3092 fixed to the lower end of the planetary gear 305. The stator 3091 is fixed below the rotating disk 307 and only moves around the center of the rotating disk 307 without rotating itself. The rotor 3092 rotates around the center of the rotating disk 307 and also rotates inside the stator 3091. Its upper end is connected to the planetary gear 305 and is directly driven to rotate by the planetary gear 305.
[0027] like Figure 4 As shown, the stator 3091 includes an outer wall 3093, a sealing plate 3094 fixed to the lower end of the outer wall 3093, and an inner wall 3095 fixed to the upper end of the sealing plate 3094. The outer wall 3093 and the inner wall 3095 form an annular region, providing space for the rotor 3092 to rotate. The sealing plate 3094 seals one end of the annular region, so that the slurry can only flow into the annular region through the first opening 3096, and after being stirred by the rotor 3092, it flows out through the through hole 3099 through the second opening 3098.
[0028] like Figure 4 As shown, a first opening 3096 is provided on the circumference of the outer wall 3093, and a notch 3097 is provided at the upper end of the outer wall 3093; when stirring, the slurry will flow into the stator 3091 through the first opening 3096 as the internal blades 3011 rotate.
[0029] like Figure 4 As shown, a second opening 3098 is provided on the circumference of the inner wall 3095; the slurry flows in from the first opening 3096 and out from the second opening 3098, so that the slurry is forced to pass through the blade 3011 and the gap between the inner wall 3095 and the outer wall 3093 each time it is stirred, and the strong turbulence will break up the agglomerated material.
[0030] like Figure 4 As shown, the sealing plate 3094 has a through hole 3099 in the center, which serves as a channel for the slurry to flow out.
[0031] like Figure 5 As shown, the rotor 3092 includes an upper fixing plate 3010, blades 3011 fixed at the lower end of the upper fixing plate 3010, and a lower fixing plate 3012 fixed at the lower end of the blades 3011. The upper fixing plate 3010 and the lower fixing plate 3012 fix the blades 3011, so that the blades 3011 remain stable when rotating. The upper fixing plate 3010 cooperates with the inner wall 3095, so that the slurry can only flow out from the through hole 3099.
[0032] like Figure 5 As shown, the lower fixed plate 3011 is annular, which restricts the rotation of the rotor 3092 within the annular area formed by the inner wall 3095 and the outer wall 3093, thus maintaining its stability during high-speed rotation.
[0033] In this battery slurry mixing vessel, the stator 3094 and rotor 3092 work together to play the following special roles:
[0034] I. Enhance the mixing effect
[0035] The outer wall 3093 and inner wall 3095 of the stator 3091 form an annular region, providing a specific rotational space for the rotor 3092. The movement of the rotor within this space generates strong shear force and turbulence on the flowing battery slurry, making it easier to break up agglomerated substances in the slurry. This special structural design ensures that the slurry can fully contact the stirring components during the stirring process, improving the stirring efficiency and uniformity.
[0036] The first opening 3096 on the outer wall 3093 of the stator 3091, the second opening 3098 on the inner wall 3095, and the through hole 3099 in the center of the sealing plate 3094 work together to guide the slurry to form a specific flow path between the stator 3091 and the rotor 3092. The slurry flows in through the first opening 3096, is agitated by the rotor 3092, flows out through the second opening 3098, and is then discharged through the through hole 3099. During this process, the slurry is forced through the gaps between the blades 3011 and the inner wall 3095 and the outer wall 3093, generating strong turbulence, which further enhances the dispersing effect on agglomerated materials.
[0037] II. Improve the uniformity of mixing
[0038] The combination of stator 3091 and rotor 3095 makes the stirring more complex and comprehensive. The rotation of rotor 3092 inside stator 3091 and its revolution around the center of rotating disk 307, combined with the overall movement of planetary gear 305, enable stirring wheel 309 to apply force to slurry in different directions, thereby greatly reducing the stirring dead zone and ensuring that the battery slurry can be uniformly mixed throughout the container 310.
[0039] The stationary position of the stator 3091 and the rotational motion of the rotor 3092 work together to continuously change the flow direction and speed of the slurry during the mixing process, which further promotes the mixing of different parts of the slurry and improves the uniformity of the mixing.
[0040] III. Ensure the stability of stirring.
[0041] The outer wall 3093, inner wall 3095, and sealing plate 3094 of the stator 3091 provide stable support and a closed working environment for the rotor 3092. The lower fixing plate 3012 is annular, restricting the rotor 3092 to rotate within the annular area and maintaining the stability of the rotor 3092 when rotating at high speed. This structural design can prevent the rotor 3092 from shaking or shifting during the stirring process, ensuring the reliability and stability of the stirring process.
[0042] Working principle:
[0043] The battery slurry is placed in container 310, and motor 2 is started. Motor 2 drives transmission shaft 303, which drives sun gear 304. Sun gear 304 transmits power to planet gear 305, which rotates around the sun gear 304 and also rotates on its own axis. Planet gear 305 drives rotor 3092 to revolve and rotate on its own axis. Slurry flows in from the first opening 3096 and flows out from the second opening 3098 through the through hole 3099 after being pushed by blade 3011. When the slurry passes through the gap between the outer wall 3093, the inner wall 3095, and the blade 3011, the agglomerated material inside is dispersed by turbulence, making the battery slurry more evenly stirred.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
