[0025] The principle of this utility model This utility model features a rotary multi-distribution inlet ferrosilicon submersible furnace charging plate design that achieves uniform material distribution.

The speed and number of rotations of the motor are set according to the gear-ring transmission ratio, so that the raw material is periodically aligned with different feeding parts 5 through the bottom feeding hole 6, realizing dynamic distribution. Two-stage buffer feeding: The raw material in the annular storage hopper 4 enters the storage tank 8 through the first feeding pipe 9. The level gauge 13 monitors the storage volume in real time, and the switch valve 12 controls the opening and closing of the discharge port 10. The combination of buffer storage and real-time monitoring can accurately control the amount of material fed at one time, while preventing the raw material from spilling. The raw material is accurately dropped into the feed port of the electric arc furnace through the second feeding pipe 11, avoiding dust dispersion. The controller adjusts the timing of the switching valves based on the material level data, which can ensure that the feeding amount at each feed port is consistent and maintain a flat material surface inside the furnace.
