Description

Technical Field

[0001] The invention belongs to the field of feeders, and in particular relates to a feeder for online multi-head feeding of crucibles. Background Art

[0002] Pre-carbonized or graphitized crucibles are generally carried on a flatbed truck with multiple arranged crucibles (for example: 4 rows and 4 columns, 5 rows and 6 columns, etc.) running along the set track to the charging station for charging, and after the charging is completed, they enter the kiln body for sintering. Since the charging of pre-carbonized or graphitized crucibles requires the charging to be filled, the existing charging stations generally use manual filling or vacuum charging systems to fill battery powder. During the vacuum conveying and charging process of the material, the gas content of the material increases due to the full mixing of the material and the air. After the conveying is stopped, the material continues to remain fluffy, the material bulk density decreases, the rear crucible cannot be filled with enough material, and the filling space utilization rate is reduced. Manual filling has extremely slow filling efficiency and increased labor intensity for workers. At the same time, the entire filling process is exposed to the outside, and the material is directly in contact with the atmosphere, causing material and air pollution. Summary of the invention
