[0002] Ternary positive electrode materials usually use nickel cobalt manganese hydroxide as a ternary precursor, which is then sintered to obtain nickel cobalt manganese hydroxide as a ternary precursor material. The ternary precursor material needs to be mixed when used, and then a mixing reactor is used. The mixing reactor of the prior art usually includes a stirring motor, a reduction motor, a dispersion motor, a stirring shaft and a stirring paddle, etc. The stirring motor rotates the stirring shaft, and then the stirring shaft drives the stirring paddle to rotate, and the stirring paddle stirs and mixes the ternary precursor material. In recent years, with the expansion of the market and demand for power batteries, the ternary material industry chain is also in a state of rapid growth, which has brought about the vigorous development of the ternary precursor industry. Various ternary precursor manufacturers are expanding production. At present, the mass production reactors of ternary precursors are mostly 6m-10m. The dispersion of the reactor system has become a key point. As we all know, the precursor is agglomerated from primary particles into spherical secondary particles. During the process of stirring and mixing the materials in the reactor, the reactor body does not swing, and the stirring blades usually only rotate inside the reactor to stir and mix the materials. The fluidity of the materials is reduced, and the dispersion of the entire reaction system is poor, which makes the spherical secondary particles very easy to stick, affecting the mixing quality of the spherical secondary particles.

[0013] (1) In the ternary precursor material mixing reactor, during the process of rotating and mixing the internal materials in the reactor, the stirring shaft can rotate to drive the stirring rod to rotate to different positions inside the reactor to stir and mix the materials. The swing of the reactor can improve the fluidity of the materials, thereby improving the dispersion of the entire reaction system, so that the spherical secondary particles can move back and forth inside the reactor, preventing the spherical secondary particles from sticking to each other and improving the mixing quality of the spherical secondary particles.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0025] See also Figure 1-4 The utility model provides a technical solution: a ternary precursor material mixing reactor, comprising a circular ring base 1, the top of which is fixedly connected to two support shafts 2, the upper ends of the two support shafts 2 are fixedly connected to a clamping ring 3, and the interiors of the two clamping rings 3 are rotatably sleeved with a rotating shaft 4;
[0026] The two rotating shafts 4 have a rotating ring 5 fixedly connected to one end opposite to the other, and a reaction kettle 6 is rotatably connected to the inside of the rotating ring 5. A feed inlet 7 is provided on the top of the reaction kettle 6, and a sealing bottom cover 8 is slidably connected to the bottom of the reaction kettle 6.
[0027] The interior of the reaction kettle 6 is rotatably connected to a stirring shaft 9, a stirring rod 10 is fixedly sleeved inside the stirring shaft 9, and a rotating inclined plate 11 is fixedly connected to the upper end of the stirring shaft 9;
[0028] The surface of the annular base 1 is fixedly connected with a support rod 12 , the upper end of the support rod 12 is fixedly connected with a transmission motor 13 , and the output end of the transmission motor 13 is fixedly connected to the top of the rotating inclined plate 11 .
[0029] When the ternary precursor material mixing reactor is in use, the staff adds the material into the reactor 6 through the feed port 7, and then starts the transmission motor 13. The output end of the transmission motor 13 rotates to drive the rotating inclined plate 11 to rotate in a circle. The rotation of the rotating inclined plate 11 drives the stirring shaft 9 to rotate, and drives the reactor 6 to swing and rotate inside the rotating ring 5 through the stirring shaft 9. At this time, the reactor 6 rotates and drives the rotating ring 5 to swing up and down. The rotating ring 5 swings up and down and drives the two rotating shafts 4 to rotate inside the two clamping rings 3. During the process of the reactor 6 rotating to mix the internal materials, the rotation of the stirring shaft 9 can drive the stirring rod 10 to rotate to different positions inside the reactor 6 to stir and mix the materials. The swinging of the reactor 6 improves the fluidity of the materials, thereby improving the dispersibility of the entire reaction system, so that the spheroidal secondary particles move back and forth inside the reactor 6, preventing the spheroidal secondary particles from sticking to each other, and improving the mixing quality of the spheroidal secondary particles.
[0030] Among them, an annular groove 14 is opened inside the retaining ring 3, and a ball 15 is slidably connected inside the annular groove 14. The balls 15 are distributed in a circular shape and equidistantly inside the annular groove 14. A contact groove 16 is opened on the surface of the rotating shaft 4, and the balls 15 are slidably connected inside the contact groove 16.
[0031] As the swivel 5 swings up and down and drives the rotating shaft 4 to rotate inside the retaining ring 3, the rotating shaft 4 rotates and drives the ball 15 to roll inside the annular groove 14 through the friction between the inner wall of the surface contact groove 16 and the ball 15, thereby reducing the friction between the rotating shaft 4 and the retaining ring 3, thereby ensuring that the swivel 5 swings up and down stably.
[0032] Working principle: In the ternary precursor material mixing reactor, after the staff adds the material into the reactor 6 through the feed port 7, the transmission motor 13 is started. The transmission motor 13 drives the rotating inclined plate 11 to rotate in a circle. The rotation of the rotating inclined plate 11 drives the stirring shaft 9 to rotate, and drives the reactor 6 to swing and rotate inside the rotating ring 5 through the stirring shaft 9. At this time, the reactor 6 rotates and drives the rotating ring 5 to swing up and down. The rotating ring 5 drives the two rotating shafts 4 to rotate inside the two clamping rings 3. In the process of the reactor 6 rotating to mix the internal materials, the rotation of the stirring shaft 9 can drive the stirring rod 10 to rotate to different positions inside the reactor 6 to stir and mix the materials. The swinging of the reactor 6 improves the fluidity of the materials. In the process of the rotating ring 5 swinging up and down to drive the rotating shaft 4 to rotate inside the clamping ring 3, the rotating shaft 4 rotates and drives the rolling ball 15 to roll inside the annular clamping groove 14 through the friction between the inner wall of the surface contacting the clamping groove 16 and the rolling ball 15, thereby reducing the friction between the rotating shaft 4 and the clamping ring 3, thereby ensuring that the rotating ring 5 swings up and down stably.
[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
