Description

Technical Field

[0001] This utility model relates to the field of ternary cathode material preparation technology, and more specifically, to a quantitative feeding and isolation device for a ternary cathode material preparation reactor. Background Technology

[0002] In the fabrication of ternary precursor materials for lithium-ion batteries, co-precipitation is commonly used and carried out in a reactor. In the past, the amounts of each component of the ternary precursor were usually calculated in advance, then injected into the reactor, and mixed using the reactor's stirring device.

[0003] Traditional feeding methods may have problems such as inaccurate metering, material contamination or cross-contamination, especially when processing high-purity or highly active materials. Furthermore, after material injection, it is easy to cause uneven mixing of materials, increase reaction time, and reduce product quality. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figure 1-4 In this utility model, a quantitative feeding and conveying isolation device for a ternary cathode material preparation reactor includes a tank body 1. A servo motor 2 is fixedly installed on the top of the tank body 1. The output end of the servo motor 2 is fixedly connected to a stirring rod 3 via a coupling. The bottom end of the stirring rod 3 penetrates into the interior of the tank body 1 and is rotatably connected thereto. Three annularly distributed feed pipes 4 are inserted into the top of the tank body 1. An electronic metering valve 5 is installed on the feed pipes 4. A lifting mechanism 6 is fixedly installed inside the stirring rod 3. An isolation chamber 7, which is divided into three equal parts, is slidably installed on the outside of the stirring rod 3. Three funnel nozzles 8, which are respectively aligned and cooperate with the three feed pipes 4, are fixedly installed on the top of the isolation chamber 7. Three straight pipes 9, which are respectively connected and fixed to each inner cavity, are fixedly connected to the outside of the isolation chamber 7. The straight pipes 9 have evenly distributed drain holes 10 on their outer sides. An elastic sealing element 11 is installed inside the end of the straight pipe 9 away from the isolation chamber 7.

[0022] In this invention, the tank 1 serves as the main body of the device. During use, the lifting mechanism 6 is first activated to raise the isolation chamber 7, aligning and connecting the three funnels 8 with the three feed pipes 4. Then, the external feeding device is activated, injecting materials into the three separation spaces inside the isolation chamber 7 through the three feed pipes 4 to prevent cross-contamination. The feeding is precisely metered via the electronic metering valve 5. After feeding, the servo motor 2 is activated to rotate the stirring rod 3. The rotation of the stirring rod 3 causes the isolation chamber 7 to rotate synchronously. Under centrifugal force, the elastic sealing mechanism 11 moves outward and compresses, connecting the drain hole 10 with the interior of the isolation chamber 7. The materials inside are simultaneously and evenly ejected, resulting in a more uniform material distribution and mixing. This achieves the advantages of accurate feeding metering, cross-contamination prevention, and more uniform material distribution and mixing. It solves the problems of inaccurate metering, material contamination, or cross-contamination that may exist in existing feeding methods, especially when processing high-purity or highly active materials. Furthermore, it addresses the issue of uneven material mixing after injection, which increases reaction time and reduces product quality.

[0023] Please see Figure 2 The elastic sealing component 11 includes a sliding column 111, a spring 112, and a counterweight 113. One end of the sliding column 111 passes through and is slidably connected to the inside of the straight pipe 9, and the other end of the sliding column 111 is fixedly connected to the counterweight 113. The spring 112 is sleeved on the outside of the sliding column 111, and one end of the spring 112 is fixedly connected to the outside of the sliding column 111, while the other end of the spring 112 is fixedly connected to the inner wall of the straight pipe 9.

[0024] In this invention, the rotation of the isolation chamber 7 causes the counterweight 113 to pull the sliding column 111 and compress the spring 112 under the action of centrifugal force, so that the drain hole 10 is connected to the interior of the isolation chamber 7, and the internal material is thrown out under the action of centrifugal force.

[0025] Please see Figure 1 The isolation chamber 7 is fixedly connected to both the top and bottom with annular sealing rings 71, which are sleeved on the outside of the stirring rod 3 and slide in contact with it.

[0026] In this invention, two annular sealing rings 71 are used to seal the top of the isolation chamber 7 and the top of the chamber 7 with the stirring rod 3, respectively, thereby sealing the internal structure.

[0027] Please see Figure 2 In this design, the drain hole 10 has an inclined cross-section, with one end of the drain hole 10 tilted towards the end of the straight pipe 9 away from the isolation chamber 7. This tilt of the drain hole 10 towards the end of the straight pipe 9 away from the isolation chamber 7 allows for smoother liquid discharge along the direction of centrifugal force.

[0028] Please see Figure 1 The lifting mechanism 6 includes an electric push rod 61 and a sliding block 62. The electric push rod 61 is fixedly installed inside the stirring rod 3. The top of the electric push rod 61 is fixedly connected to the sliding block 62. The two sides of the sliding block 62 extend to the outside of the stirring rod 3 and are fixedly connected to the isolation chamber 7.

[0029] In this scheme, the electric push rod 61 is activated to drive the sliding block 62 to move vertically, thereby driving the isolation chamber 7 to adjust its height vertically along the outside of the stirring rod 3, so as to realize the docking and separation of the adjusting funnel nozzle 8 and the bottom end of the feed pipe 4.

[0030] Please see Figure 1 In this scheme, a discharge valve 12 is fixedly installed at the bottom of the tank body 1. The discharge valve 12 facilitates the discharge of material and slag after the reaction.

[0031] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
