[0002] Ternary precursors are the initial raw materials for preparing ternary cathode materials, mainly referring to nickel-cobalt-manganese or nickel-cobalt-aluminum hydroxides, which play an indispensable role in the production of new energy power batteries. The manufacturing process of ternary precursors mainly includes steps such as preparation, precipitation, washing, drying, and powder treatment. During the precipitation process, a reaction vessel is required to provide space for the reaction between the raw materials.

[0003] According to patent CN211964158U, a ternary material precursor reactor is disclosed, including a reactor body. The side wall of the reactor body is cylindrical, and the ratio of the height of the cylinder to the diameter of the cylinder is a, where 1.5 ≤ a < 2. The reactor body is equipped with an upper stirring paddle and a lower stirring paddle. The reactor body is also equipped with a feed liquid inlet pipe and an alkali liquid inlet pipe.

[0004] The above-mentioned solution improves the fluid motion state during the production of ternary material precursors, thereby increasing the sphericity of the precursor particles. However, during the implementation of the above-mentioned solution, it is difficult to ensure sufficient contact between materials, resulting in poor stirring effect of the device, which is not conducive to the fine crystallization. To address this issue, we provide a ternary material precursor reactor to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ternary material precursor reactor in order to solve the above-mentioned problems, thereby addressing the issue that the existing reactors have a relatively simple method of stirring materials, which is not conducive to crystal refinement and shaping.

[0008] Preferably, a limiting ring is fixedly connected to the outer surface of the rotating rod, and the ratchet ring is rotatably connected to the limiting ring. The limiting ring has the effect of supporting and limiting the ratchet ring.

[0009] Preferably, a connecting rod is rotatably connected to the top of the reactor body, and a telescopic rod is fixedly connected to the bottom surface of the connecting rod. The telescopic end of the telescopic rod is fixed to the rotating rod, and the telescopic rod serves as a transmission connection.

[0010] Preferably, a stirring motor is fixedly installed on the top surface of the reactor body, and the connecting rod is fixedly connected to the output shaft of the stirring motor, so that the stirring motor provides power for the stirring of the stirring blades.

[0011] Preferably, the bottom end of the reactor body is fixedly connected to a discharge pipe, and an electric valve is fixedly installed inside the discharge pipe, which can control the opening and closing of the discharge pipe.

[0014] This utility model provides a ternary material precursor reactor, which has the following beneficial effects:

[0015] 1. This utility model, by setting up components such as annular slides, spherical sliders, ratchet rings, and pawls, and through the transmission and cooperation between the rotating rod and the telescopic rod, enables the rotating rod to drive the stirring blades to rotate and move up and down while rotating. This enriches the stirring forms of the stirring blades, effectively improves the stirring effect of the device, ensures full contact between materials, increases the reaction rate of the device, and is conducive to the subsequent fine crystal formation. At the same time, it can also clean the inner wall of the reactor body, avoiding the waste of raw materials caused by the adhesion of crystals to the inner wall of the reactor body.

[0016] 2. This utility model effectively realizes the transmission connection between the connecting rod and the rotating rod through the setting of the telescopic rod, so that the rotating rod can also reciprocate up and down during rotation, thereby changing the stirring mode of the device. The device is not limited to simple rotational stirring, but can move up and down while rotating and stirring, which effectively improves the stirring effect of the device. Through the setting of the cleaning rod, the device can automatically clean the inner wall of the reactor body when the motor reverses, which greatly reduces the workload of the staff in cleaning the adhering crystals on the inner wall of the reactor body and reduces the waste of raw materials.

[0026] This utility model embodiment provides a ternary material precursor reactor.

[0027] Please see Figure 1 and Figure 2 The reactor includes a reactor body 1, with a feed pipe 9 and an vent pipe 10 fixedly connected to the top surface of the reactor body 1. A pressure relief valve 11 is fixedly installed at the top of the reactor body 1. The pressure relief valve 11 can automatically open and close according to the working pressure of the system, which can protect the equipment and pipelines, keep the pressure in the equipment and pipelines within the set pressure range, prevent accidents that may occur due to overpressure, and improve the safety of the device. The feed pipe 9 facilitates the staff to transport raw materials into the reactor body 1 for reaction.

[0028] The bottom end of the reactor body 1 is fixedly connected to the discharge pipe 6. An electric valve 7 is fixedly installed inside the discharge pipe 6. The electric valve 7 can automatically control the opening and closing of the discharge pipe 6 to facilitate the discharge of the mixture that has completed the reaction inside the reactor body 1. The electric valve 7, the pressure relief valve 11 and the stirring motor 5 are all existing technologies, and will not be described in detail in this application.

[0029] Please see Figure 2 The reactor body 1 is equipped with a rotating rod 2 inside, and a support plate 8 is fixedly installed inside the reactor body 1. The rotating rod 2 passes through the support plate 8 and is slidably connected to the support plate 8. The rotating rod 2 can slide in the rotating rod 2 and rotate in the support plate 8. The support plate 8 provides a certain degree of limitation and support for the rotation and sliding of the rotating rod 2. A retaining ring is fixed on the outer surface of the rotating rod 2 to prevent the rotating rod 2 from detaching from the support plate 8 during the reciprocating lifting and lowering process, which would reduce the stability of the rotating rod 2. The top surface of the support plate 8 has an inclined sliding surface design, which can reduce the probability of the mixed reactants accumulating on the top surface of the support plate 8.

[0030] Please see Figure 3 , Figure 4 and Figure 5 A set of stirring blades 3 are fixedly connected to the outer surface of the rotating rod 2. When the rotating rod 2 rotates inside the reactor body 1, it can drive the stirring blades 3 to rotate inside the reactor body 1. The rotation of the stirring blades 3 can stir the reactants inside the reactor body 1, thereby accelerating the mixing rate of the reactants. During the rotation process, the rotating rod 2 will also reciprocate and rise at a certain frequency under the action of the transmission mechanism 4, thereby improving the stirring and mixing effect of the stirring blades 3 and ensuring full contact between materials.

[0031] The reactor body 1 is equipped with a transmission mechanism 4. The transmission mechanism 4 includes a fixed sleeve 401 and a ratchet ring 405. The fixed sleeve 401 is fixed on the inner top wall of the reactor body 1. Through the transmission mechanism 4, the drive of the stirring motor 5 can be converted into the motion state of the rotating rod 2 rotating and reciprocating up and down. This allows the rotating rod 2 to drive the stirring blade 3 up and down and rotate, effectively increasing the stirring mode of the device, improving the stirring effect of the device, and facilitating the refinement and shaping of crystals.

[0032] Please see Figure 1 , Figure 2 and Figure 3 A stirring motor 5 is fixedly installed on the top surface of the reactor body 1. The connecting rod 404 is fixedly connected to the output shaft of the stirring motor 5. When the stirring motor 5 is started, it can drive the connecting rod 404 to rotate at the top of the reactor body 1. The rotation of the connecting rod 404 can provide a transmission effect for the rotation and lifting of the rotating rod 2, and provide power for the subsequent cleaning rod 407 to clean the inner wall of the reactor body 1.

[0033] Please see Figure 3 and Figure 4A connecting rod 404 is rotatably connected to the top of the reactor body 1. A telescopic rod 409 is fixedly connected to the bottom surface of the connecting rod 404. The telescopic end of the telescopic rod 409 is fixed to the rotating rod 2. The telescopic rod 409 has special existing structures such as protrusions and elastic pins inside, which can realize the function of only extending and not rotating during the transmission process. That is, when the connecting rod 404 rotates, it can drive the rotating rod 2 to rotate through the telescopic rod 409. Under the limiting action of the annular slide 402 and the spherical slider 403, the rotating rod 2 can also rise and fall while rotating, thereby driving the telescopic rod 409 to extend and retract.

[0034] The inner wall of the fixed sleeve 401 is provided with an annular slide rail 402. A spherical slider 403 is fixedly connected to the outer surface of the rotating rod 2. The spherical slider 403 is adapted to the annular slide rail 402. When the rotating rod 2 rotates with the telescopic rod 409, the spherical slider 403 will also rotate. Under the limiting action of the annular slide rail 402, the rotation of the spherical slider 403 can drive the rotating rod 2 to move up and down repeatedly, thereby changing the stirring mode of the device. This allows the device to move up and down while rotating and stirring, which effectively improves the stirring effect of the device.

[0035] Please see Figure 3 and Figure 5 A pawl 406 is fixedly connected to the outer surface of the rotating rod 2. The ratchet ring 405 is adapted to the pawl 406. The pawl 406 has a unidirectional rotation restriction effect, so that when the rotating rod 2 rotates forward, the pawl 406 can rotate normally inside the ratchet ring 405. When the rotating rod 2 rotates in reverse, the pawl of the pawl 406 will engage with the ratchet ring 405, thereby locking with the ratchet ring 405. At this time, the rotation of the rotating rod 2 can drive the ratchet ring 405 to rotate in reverse through the pawl 406, thereby providing power for the cleaning operation of the cleaning rod 407.

[0036] A set of cleaning rods 407 are fixedly connected to the outer surface of the ratchet ring 405. Each cleaning rod 407 is slidably connected to the reactor body 1. When the rotating rod 2 drives the ratchet ring 405 to rotate through the pawl 406, the ratchet ring 405 can drive the cleaning rods 407 to rotate inside the reactor body 1. Cleaning brushes are installed at both ends of the cleaning rods 407. The rotation of the cleaning rods 407 can clean the reaction mixture adhering to the inner wall of the reactor body 1, avoiding the waste of raw materials caused by the crystals adhering to the inner wall of the reactor body 1.

[0037] A limiting ring 408 is fixedly connected to the outer surface of the rotating rod 2. The ratchet ring 405 is rotatably connected to the limiting ring 408. The limiting ring 408 plays the role of supporting and restricting the ratchet ring 405, preventing the ratchet ring 405 from disengaging from the pawl 406, and ensuring that the transmission process of the device can proceed smoothly.

[0038] Working principle: When the operator wants to use this device to prepare ternary material precursors, the reaction materials are first fed into the reactor body 1 through the feed pipe 9. Then, the stirring motor 5 is started. The stirring motor 5 drives the connecting rod 404 to rotate. The rotation of the connecting rod 404 drives the rotating rod 2 to rotate through the telescopic rod 409. The rotation of the rotating rod 2 drives the stirring blade 3 to rotate inside the reactor body 1, thereby enabling the stirring blade 3 to stir the reaction mixture. When the rotating rod 2 rotates, the spherical slider 403 slides inside the annular slide 402, thereby enabling the rotating rod 2 to... The stirring blades 3 can be raised and lowered while rotating, which effectively enriches the stirring mode of the stirring blades 3. The stirring blades 3 can be raised and lowered back and forth while rotating and stirring, which fully ensures the contact between materials and improves the reaction efficiency. After the reaction is completed, the staff can clean the inner wall of the reactor body 1 by reversing the stirring motor 5. When the stirring motor 5 reverses and drives the rotating rod 2 to reverse, the pawl 406 will engage with the ratchet ring 405. At this time, the ratchet ring 405 will rotate inside the reactor body 1 with the rotation of the rotating rod 2, thereby driving the electric valve 7 to clean the inner wall of the reactor body 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
