Description

Technical Field

[0001] This utility model relates to the field of lithium battery anode material mixing technology, and in particular to a differential speed homogenizer. Background Technology

[0002] Homogenization is one of the important processes in lithium battery manufacturing. Homogenization mainly uses high-speed rotating blades to provide high shear force to disperse the slurry. Existing raw material stirring methods generally use stirring blades and spiral shafts for stirring.

[0003] Existing mixing technologies are not ideal for thoroughly mixing raw materials within the mixing space, easily leading to uneven mixing. Furthermore, current mixing devices cannot adequately mix lithium battery negative electrode slurries, resulting in poor device performance. Current spiral shaft-type rapid homogenizing devices for lithium battery slurries tend to have slurry adhering to the inner walls during use, leading to material waste. Raw materials are also difficult to remove from the mixing equipment, increasing subsequent cleaning work. Moreover, the single mixing method results in insufficient mixing and uneven distribution.

[0004] Therefore, there is an urgent need for a differential speed homogenizer to make the homogenizer more uniform and reduce the residue on the inner wall. Utility Model Content

[0005] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a differential speed homogenizer.

[0006] The technical solution of this utility model is as follows:

[0007] A differential speed homogenizer includes a planetary gear mechanism, a material-turning agitator, and two or more material-scraping agitators. The planetary gear mechanism includes a sun gear, an internal gear ring, and two or more planet gears. The sun gear is located in the center of the internal gear ring, and the planet gears are arranged in a circumferential array and meshed between the sun gear and the internal gear ring. The gear shafts of the planet gears are rotatably connected to the same planet carrier. The material-turning agitator is connected to the sun gear, and each material-scraping agitator is connected to a planet gear.

[0008] Preferably, it also includes a geared motor, which is mounted upside down on a motor mounting bracket, which is fixedly mounted on an internal gear ring, and the drive shaft of the geared motor is connected to the sun gear via a coupling.

[0009] Preferably, the material-turning agitator is an agitator shaft with spiral blades, and the upper end of the material-turning agitator is fixedly connected to the sun gear.

[0010] Preferably, the scraper agitator is an agitator shaft with planar blades, and the upper end of the scraper agitator is fixedly sleeved with a planetary gear.

[0011] Preferably, the upper and lower side walls of the internal toothed ring are respectively provided with limiting baffles, and the edge of the internal toothed ring is embedded between the upper and lower limiting baffles.

[0012] Preferably, it also includes a stabilizing bracket, with the material-turning agitator and each scraping agitator rotatably mounted on the stabilizing bracket.

[0013] Preferably, the gap width d1 between the material-turning agitator and the material-scraping agitator is 5-8cm; the gap width d2 between the material-scraping agitator and the inner wall of the outer mixing container is 3-58cm.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model sets up a circumferential array of scraping and stirring paddles distributed around the outer periphery of the turning and stirring paddle, and with the help of the transmission action of the planetary gear mechanism, it can drive the central turning and stirring paddle to rotate with only one geared motor, while driving each of the surrounding scraping and stirring paddles to rotate on their own axis and revolve around the turning and stirring paddle. The structure is compact and the layout is reasonable.

[0016] 2. The material-turning stirring paddle of this utility model is designed with a spiral blade stirring shaft structure, which can turn the material from top to bottom during operation. At the same time, the material-scraping stirring paddle is designed with a planar blade stirring shaft structure, which can stir the material during operation. The two are combined to achieve horizontal stirring while also turning the material up and down, making the material mixing in the mixing container more efficient and uniform.

[0017] 3. The gap width between the scraping agitator and the turning agitator, as well as between the scraping agitator and the inner wall of the external mixing container, is specially set in this utility model. There is also a speed difference between the three. Therefore, when rotating, it can shear and mix the material, and has a better dispersion effect on agglomerated materials.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figures 1 to 5 A differential speed homogenizer includes a planetary gear mechanism 100, a material-turning agitator 200, and two or more scraper agitators 300. The planetary gear mechanism 100 includes a sun gear 110, an internal gear ring 120, and two or more planetary gears 130. The sun gear 110 is located at the center of the internal gear ring 120. Each planetary gear 130 is arranged in a circumferential array and meshed between the sun gear 110 and the internal gear ring 120. The gear shafts 140 of each planetary gear 130 are rotatably connected to the same planet carrier 150. The material-turning agitator 200 is connected to the sun gear 110, and each scraper agitator 300 is connected to the planetary gears 130. The material-turning agitator 200 is an agitator shaft with helical blades, and its upper end is fixedly sleeved with the sun gear 110. The scraper agitator 300 is an agitator shaft with planar blades, and its upper end is fixedly sleeved with the planetary gears 130.

[0027] See Figure 2 A differential homogenizer also includes a geared motor 400, which is inverted and mounted on a motor mounting bracket 410. The motor mounting bracket 410 is fixedly mounted on an internal gear ring 120. The drive shaft of the geared motor 400 is connected to the sun gear 110 via a coupling 420.

[0028] Furthermore, limit baffles are provided on both the upper and lower side walls of the internal gear ring 120. The edge of the internal gear ring 120 is embedded between the upper and lower limit baffles. The limit baffles can prevent the planetary gear 130 from derailing and increase the stability of the overall structure.

[0029] Furthermore, a differential slurry mixer also includes a stabilizing bracket 500, a material-turning mixing blade 200, and various scraping mixing blades 300, which are rotatably mounted on the stabilizing bracket 500, thereby enhancing the stability of the mixer.

[0030] Furthermore, the gap width d1 between the material-turning agitator 200 and the material-scraping agitator 300 is 5-8cm; the gap width d2 between the material-scraping agitator 300 and the inner wall of the outer mixing container is 3-58cm; this allows the material between the material-scraping agitator 300 and the material-turning agitator 200 to undergo secondary shearing, mixing and dispersion, thereby achieving a highly efficient differential speed homogenization mixing effect where the material-scraping agitator 300 provides lateral dispersion and mixing, the material-turning agitator 200 provides longitudinal dispersion and lateral shearing, and the two blades perform secondary dispersion.

[0031] Meanwhile, by specially setting the gap width between the scraper agitator 300 and the tilting agitator 200, as well as between the scraper agitator 300 and the inner wall of the outer mixing container, the special spacing setting can achieve a near-optimal mixing effect, reduce material residue on the inner wall, and thus reduce the difficulty of cleaning the inner wall. At the same time, there is a speed difference between the three, so when rotating, it can play a shearing and mixing role on the material, and has a better dispersion effect on agglomerated materials.

[0032] The working principle of this utility model:

[0033] In this invention, the material to be stirred is first placed into a stirring container, and then the device in this embodiment is placed inside. The geared motor 400 is inverted and mounted on a motor mounting bracket 410, which is fixedly mounted on an internal gear ring 120. The drive shaft of the geared motor 400 is connected to the sun gear 110 via a coupling 420. The geared motor 400 is started first, which in turn drives the sun gear 110 to rotate. By circumferentially distributing scraper-stirring paddles 300 around the turning-stirring paddle 200, and with the transmission of the planetary gear mechanism 100, only one geared motor 400 is needed to drive the central turning-stirring paddle 200 to rotate, while simultaneously driving the surrounding scraper-stirring paddles 300 to rotate on their own axes and revolve around the turning-stirring paddle. The turning-stirring paddle 200 is a spiral-shaped blade stirring shaft structure, capable of turning the material from top to bottom during operation. Simultaneously, the scraper-stirring paddle 300 is a planar blade stirring shaft structure, capable of stirring the material... The two materials, combined, achieve both horizontal stirring and vertical tumbling, resulting in more efficient and uniform mixing of materials in the mixing container. Furthermore, the gap width d1 between the tumbling mixing blade 200 and the scraping mixing blade 300 is 5-8 cm; the gap width d2 between the scraping mixing blade 300 and the inner wall of the outer mixing container is 3-58 cm. This allows for secondary shearing, mixing, and dispersion of materials between the scraping mixing blade 300 and the tumbling mixing blade 200, achieving a highly efficient differential speed homogenization mixing effect where the scraping mixing blade 300 provides horizontal dispersion and mixing, while the tumbling mixing blade 200 provides longitudinal dispersion and horizontal shearing. The gap widths between the scraping mixing blade 300 and the tumbling mixing blade 200, as well as between the scraping mixing blade 300 and the inner wall of the outer mixing container, are specially designed, and a speed difference exists between the three. Therefore, during operation, the blades can shear and mix the materials, resulting in better dispersion of agglomerated materials.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
