Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ternary precursor preparation equipment, and in particular to a ternary precursor centrifuge discharge port anti-scattering device and a ternary precursor centrifuge. Background Art
[0002] The ternary precursor material is nickel cobalt manganese hydroxide Ni x Co y Mn (1-x-y) (OH)2, a precursor product of ternary composite positive electrode materials, is made of nickel salt, cobalt salt and manganese salt. The ratio of nickel, cobalt and manganese can be adjusted according to actual needs, and the finished product is a solid powder.
[0003] The preparation of positive electrode materials requires centrifugation of the ternary precursor slurry. The working principle of the centrifuge: The drum and distribution plate rotate at a pre-set appropriate speed. The ternary precursor slurry passes through the feed pipe to the distribution plate, where it gains centrifugal force and tends to the drum wall. The solid phase material is intercepted by the filter medium and accumulates on the inner wall of the drum to form a filter cake. Under the action of the centrifuge, the liquid phase passes through the filter cake and is thrown out of the drum through the small holes on the drum, achieving solid-liquid phase separation. When the solid-liquid separation meets the requirements, washing can be carried out according to the process requirements. After washing meets the requirements, the solid phase and the washing liquid are separated. After drying, the unloading stage begins. At this time, the centrifuge enters low-speed operation. The scraper cylinder pushes the scraper under the action of hydraulic oil to scrape off the filter cake and discharge it from the discharge port.
[0004] In the prior art, materials may leak during discharge from the discharge port.
[0005] In view of this, the present utility model is proposed. Utility Model Content

[0032] Example
[0033] Please refer to Figure 1 The anti-scattering device of the discharge port 6 of the ternary precursor centrifuge provided in this embodiment includes a material bag 3 and a clamp 5.
[0034] The upper end of the bag 3 is sealed and fitted over the centrifuge discharge port 6. A clamp 5 is looped around the upper end of the bag 3, securing it to the centrifuge discharge port 6. An elastic sealing ring 2 is positioned around the lower end of the bag 3, allowing the lower end of the bag 3 to be tightly fitted around buckets 1 of varying sizes.
[0035] The clamp 5 is looped around the upper end of the bag 3, securing it to the centrifuge discharge port 6. This ensures a tight and sealed fit between the upper end of the bag 3 and the centrifuge discharge port 6, while also ensuring a tight and sealed fit between the lower end of the bag 3 and the barrel 1. The elastic sealing ring 2, with its automatic tightening function, allows for compatibility with barrels 1 of varying sizes, significantly improving versatility and significantly reducing the risk of material dispersion and leakage. Overall, this improves the workshop production environment, saves costs, and increases production efficiency.
[0036] In some optional embodiments, the material bag 3 is a cloth bag. This type of material bag 3 is light, low-cost, and highly applicable.
[0037] In some optional embodiments, the clamp 5 is a clamp structure, and the bag 3 is locked to the centrifuge discharge port 6 through the cooperation of an annular plate and bolts.
[0038] In some optional embodiments, the elastic sealing ring 2 is a rubber band, which has the characteristic of good stretchability.
[0039] In some optional embodiments, the centrifuge discharge port 6 is provided with an annular material ring, which cooperates with the clamp 5 .
[0040] The clamp 5 can lock the material bag 3 onto the annular material ring, or lock it above the annular material ring. By utilizing the annular material ring, the clamp 5 can be prevented from loosening, which greatly improves the installation efficiency.
[0041] In some optional embodiments, the annular material ring may be made of polyvinyl chloride, also known as PVC.
[0042] In some optional embodiments, the centrifuge discharge port 6 can be made of polypropylene homopolymer (PPH). PPH is a thermoplastic material with advantages such as chemical resistance, wear resistance, and high temperature resistance. Setting the centrifuge discharge port 6 to PPH can also reduce costs.
[0043] In addition, in some other optional embodiments, it is not excluded that the centrifuge discharge port 6 adopts other mature materials in the prior art.
[0044] In some optional embodiments, the anti-dispersion device of the ternary precursor centrifuge discharge port 6 also includes a circular ring plate 4, which is used to be mounted on the centrifuge discharge port 6. The circular ring plate 4 is spaced apart from the clamp 5 and is located at the lower end of the clamp 5 and the centrifuge discharge port 6; the circular ring plate 4 is used to support the inner wall of the material bag 3 to prevent the lower end of the centrifuge discharge port 6 from contacting the material bag 3.
[0045] The annular plate 4 can be provided to prevent the centrifuge discharge port 6 from contacting the material bag 3, thereby preventing the material bag 3 from being wetted. The above arrangement is conducive to material discharge and improves production efficiency.
[0046] In some optional embodiments, the distance between the clamp 5 and the lower end of the centrifuge discharge port 6 can be 80mm to 100mm, for example, 80mm, 82mm, 85mm, 88mm, 90mm, 92mm, 95mm, 98mm or 100mm, or other values within the range of 80mm to 100mm.
[0047] The distance between the clamp 5 and the lower end of the centrifuge discharge port 6 should not be too large, otherwise the length of the bag 3 will be wasted; the distance between the clamp 5 and the lower end of the centrifuge discharge port 6 should not be too small, otherwise the centrifuge discharge port 6 will contact the bag 3.
[0048] In some optional embodiments, the distance between the annular plate 4 and the lower end of the centrifuge discharge port 6 may be 30 mm to 50 mm, for example, 30 mm, 32 mm, 35 mm, 38 mm, 40 mm, 42 mm, 45 mm, 48 mm, or 50 mm, or other values within the range of 30 mm to 50 mm.
[0049] The distance between the annular plate 4 and the lower end of the centrifuge discharge port 6 should not be too large, otherwise it will be difficult to open the material bag 3; the distance between the annular plate 4 and the lower end of the centrifuge discharge port 6 should not be too small, otherwise it will easily cause the centrifuge discharge port 6 to contact the annular plate 4, and the liquid flowing out of the centrifuge discharge port 6 may wet the material bag 3 through the annular plate 4.
[0050] In some optional embodiments, the diameter of the centrifuge discharge port 6 can be 300mm to 320mm, for example, 300mm, 302mm, 305mm, 308mm, 310mm, 312mm, 315mm, 318mm or 320mm, etc., or other values within the range of 300mm to 320mm.
[0051] Accordingly, the diameter of the annular plate 4 may be 390 mm to 410 mm, such as 390 mm, 392 mm, 395 mm, 398 mm, 400 mm, 402 mm, 405 mm, 408 mm or 410 mm, or other values within the range of 390 mm to 410 mm.
[0052] That is, the size of the annular plate 4 is slightly larger than the size of the centrifuge discharge port 6, so that the casing of the material bag 3 can be opened.
[0053] In some optional embodiments, an elastic sealing ring 2 is also provided around the upper end of the bag 3 so that the bag 3 is tightly sealed to the centrifuge discharge port 6 under the action of the clamp 5 .
[0054] It can be understood that the upper and lower openings of the material bag 3 are both wrapped with elastic sealing rings 2 to effectively seal the upper and lower ends of the material bag 3.
[0055] In some optional embodiments, the anti-scattering device of the discharge port 6 of the ternary precursor centrifuge further includes a plurality of barrels 1 of different sizes, and any one of the barrels 1 is adapted to the lower end of the bag 3 .
[0056] For example, Figure 1 The diameter of the barrel 1 shown is 860 mm. In other specific scenarios, a barrel 1 with a diameter of 840 mm or a barrel 1 with a diameter of 880 mm can also be used according to actual conditions.
[0057] In some optional embodiments, the bucket 1 is provided with a plurality of earrings. By providing the earrings on the bucket 1, it is convenient to lift the bucket 1.
[0058] For example, the earrings may also be made of PPH material.
[0059] For example, the earrings may be provided at the upper end or the lower end of the bucket 1 .
[0060] The number of earrings can be 4 for example, but it is not excluded that the number can be 2 or 6, etc.
[0061] In some optional embodiments, the bucket 1 can be equipped with wheels for easy pushing. In addition, when used, the bucket 1 can also be placed on a traveling vehicle for easy transfer.
[0062] Based on the above, the ternary precursor centrifuge provided in this embodiment has at least the following advantages:
[0063] The sealing operation at the upper and lower ends of the bag 3 prevents leakage from existing discharge ports, improves product productivity, and overcomes the leakage defects of existing material receiving devices. Furthermore, the design of the circular plate 4 and elastic sealing ring 2 in the bag 3 achieves a sealed and waterproof effect. By attaching the elastic sealing ring 2 to the lower end of the bag, it can accommodate buckets 1 of varying sizes.
[0064] In summary, the anti-scattering device for the discharge port 6 of a ternary precursor centrifuge provided by the present invention includes a material bag 3 and a clamp 5. The upper end of the material bag 3 is used to be sealed and fitted to the discharge port 6 of the centrifuge. The clamp 5 is looped around the upper end of the material bag 3, thereby fastening the upper end of the material bag 3 to the discharge port 6 of the centrifuge. The above method can make the upper end of the material bag 3 and the discharge port 6 of the centrifuge sealed and fastened. In addition, the lower end of the material bag 3 is provided with an elastic sealing ring 2, so that the lower end of the material bag 3 can be tightly sealed around the material barrels 1 of different sizes under the action of the elastic sealing ring 2. This setting can also make the lower end of the material bag 3 tightly fit with the material barrel 1; the elastic sealing ring 2 can use the automatic tightening function to match with the material barrels 1 of different sizes, which greatly improves the versatility and greatly reduces the probability of material dispersion and leakage. Overall, it can improve the workshop production environment, save costs, and improve production efficiency.
[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
