Specific implementation mode
[0030] Example 1, as Figure 1-8 shown, the present utility model provides a technical solution: a sealing bucket device for ternary battery precursor materials, including a frame 3 and a material receiving bucket 6. A blanking bucket 1 is fixedly installed at the top of the frame 3, a sealing device 5 is arranged on the upper part of the frame 3, and a filtration device 4 is arranged on the top of the sealing device 5.
[0031] During use, when the upstream equipment meets the requirements for blanking and blanking is needed, the operator places the material receiving bucket 6 directly below the frame 3, and the sealing device 5 moves downward, and the upper end of the material receiving bucket 6 is sealed; at this time, blanking is carried out through the blanking bucket 1, so that the ternary battery precursor material will fall into the material receiving bucket 6 under the action of gravity. After blanking, it is left standing for five minutes, and then the material receiving bucket can be forklifted away.
[0032] Refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8As shown in the figure, in this embodiment, the sealing device 5 includes four fixed plates 51 fixedly connected to the upper part of the frame 3. The inner walls of the four fixed plates 51 are all fixedly installed with cylinders 52. The lower parts of the four cylinders 52 are all fixedly connected with connecting blocks 53. One side of the four connecting blocks 53 is commonly fixedly connected with a first rectangular frame 54. One side of the first rectangular frame 54 is fixedly connected with a connecting plate 55. One side of the connecting plate 55 is fixedly connected with a second rectangular frame 56. A gasket slot 57 is opened on one side of the second rectangular frame 56, and a rubber gasket 58 is clamped on the inner wall of the gasket slot 57. By setting the sealing device 5, before the ternary precursor material in the feeding hopper 1 is fed, the cylinder 52 can be started, so that the cylinder 52 drives the connecting block 53 to move downward, and then the second rectangular frame 56 moves downward, and the rubber gasket 58 on the inner wall of the gasket slot 57 moves downward, so that the rubber gasket 58 can closely adhere to the top of the receiving hopper 6, so that there is no gap between the receiving hoppers 6, and the dust generated during the feeding process of the ternary precursor material will not overflow, and thus will not affect the health of the staff. A coating 101 is provided on the inner wall of the feeding hopper 1, and the material of the coating 101 is polytetrafluoroethylene material. By setting the coating 101 with the material of polytetrafluoroethylene, the ternary precursor material in the inner wall of the feeding hopper 1 can be prevented from sticking to the inner wall of the feeding hopper 1, and at the same time, the ternary precursor material can be prevented from rubbing against the inner wall of the feeding hopper 1. The cross-section of the inner wall of the gasket slot 57 is T-shaped, and the cross-section of the outer surface of the rubber gasket 58 is T-shaped. By setting the gasket slot 57 and the rubber gasket 58 to be T-shaped, the rubber gasket 58 can be clamped on the inner wall of the gasket slot 57, and the rubber gasket 58 can be prevented from falling off. A feeding hole 59 is opened on the top of the connecting plate 55, and a feeding ring 510 is fixedly connected to the inner wall of the feeding hole 59. The inner diameter of the inner wall of the feeding ring 510 is adapted to the outer diameter of the feeding hopper 1. Through the feeding ring 510, when the feeding ring 510 moves downward, the inner wall can always closely adhere to the outer surface of the feeding hopper 1, and thus the leakage of the ternary precursor material and the generation of dust can be effectively avoided.
[0033] Referring to Figure 6 and Figure 7 As shown in the figure, the filtering device 4 includes a cylinder 42. A circular hole 41 fixedly connected to the outer surface of the cylinder 42 is opened on the top of the connecting plate 55. A threaded groove 45 is opened on the outer surface of the cylinder 42. By setting the circular hole 41 and the cylinder 42, the air pressure in the receiving hopper 6 can be balanced when the material falls, and the imbalance of air pressure can be avoided. A circular ring 43 is threadedly connected to the outer surface of the threaded groove 45, and a filter cloth 44 is fixedly installed on the inner wall of the circular ring 43. By setting the filter cloth 44, the filter cloth 44 can effectively prevent the dust from flying out and at the same time realize air permeability.
[0034] Working principle: When in use, before the ternary precursor material in the feeding bucket 1 is fed, the air cylinder 52 can be started, so that the air cylinder 52 drives the connecting block 53 to move downward, and then the second rectangular frame 56 moves downward, and the rubber pad 58 on the inner wall of the gasket slot 57 moves downward, so that the rubber pad 58 can closely adhere to the top of the receiving bucket 6, so that there is no gap between the receiving buckets 6. At the same time, during the feeding process, the internal air pressure is greater than the external air pressure, and through the cylinder 42 and the filter cloth 44, the internal air pressure can be balanced.
