Description
Technical Field
[0001] This utility model belongs to the field of crucible filling technology, and in particular relates to an automatic filling device for graphitized square crucibles. Background Technology
[0002] In the carbonization process of lithium battery anode material preparation, artificial graphite powder or natural graphite powder needs to be placed in a crucible and calcined.
[0003] For example, patent CN217076295U discloses a graphitization crucible filling device, including a support, a buffer hopper, a motor, and a screw rod. The buffer hopper is fixed on the support and has an inlet and an outlet. The motor is located above the buffer hopper and connected to one end of the screw rod. The other end of the screw rod passes through the buffer hopper and is positioned at the outlet. A stirring blade is provided on the screw rod to stir the material in the hopper. The beneficial effects of this invention are: compared with the prior art, this invention has a simple structure, uses a screw to transport the material downwards, and has a stirring blade above the screw. The stirring blade stirs the material in the buffer hopper as the screw rod rotates, making the material entering the screw uniform. By combining the stirring blade with the screw, uniform material drop can be ensured, increasing the material density.
[0004] Existing automated filling devices for graphitized square crucibles typically require pushing the crucible directly below the filling port to meet dust-free requirements. However, the crucible's weight makes this difficult. Therefore, we propose an automated filling device for graphitized square crucibles. Utility Model Content
