The submerged arc furnace is composed of a feeding system, a smoke hood, a furnace body, an electrode column, a secondary busbar and other systems; the feeding system is composed of a silo, a feeding pipe and the like. The silo stores the raw materials required for smelting. The raw materials are intermittently (or continuously) fed into the furnace body through the feeding pipe. The silo needs to be continuously replenished with raw materials.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2 In the embodiment of the utility model, a hopper circulation unloading mechanism of a material distribution system comprises an ore-heating furnace 1, an annular material distribution plate 2 and a material pipe 3. A plurality of material pipes 3 are installed in an annular manner with equal intervals above the ore-heating furnace 1. An annular material distribution plate 2 is installed above the material pipe 3. A fixing plate 4 is installed in the middle of the annular material distribution plate 2. A bearing seat 5 is installed in the middle of the fixing plate 4. A rotating shaft 6 is installed on the bearing seat 5. A rotating disk 7 is installed on the rotating shaft 6. A fixing frame 8 is installed on the rotating disk 7. A hopper 9 is installed on the fixing frame 8. A discharge valve 10 is installed at the bottom of the hopper 9. The discharge valve 10 is externally connected to a switch. The fixing frame 8 is connected to the material A material guide plate 11 is installed below the discharge port of the bucket 9. The material guide plate 11 is tilted, and the lower end of the material guide plate 11 is located directly above the material pipe 3 on one side of the ore-bearing furnace 1. The material guide plate 11 is designed in this way so that the material can slide smoothly on the material guide plate 11 into the corresponding material pipe 3. A large gear 12 is installed on the rotating shaft 6, and a servo motor 14 is installed on one side of the rotating shaft 6 on the fixed plate 4. The servo motor 14 is externally connected to a servo controller, and the servo controller is used to control the angle of each rotation of the servo motor 14. A small gear 13 is installed on the top of the servo motor 14, and the small gear 13 is meshed with the large gear 12.

[0021] See also Figure 1 and Figure 3A feeder 15 is provided on one side of the ore-generating furnace 1. The discharge port of the feeder 15 is located above the hopper 9. An upper limit switch 16 and a lower limit switch 17 are installed on the hopper 9. The upper limit switch 16 and the lower limit switch 17 are externally connected to a level controller. The level controller is connected to the feeder 15. The upper limit switch 16 and the lower limit switch 17 are both Spin-11A standard type paddle level switches. The upper limit switch 16 is in a normally open state, that is, there is material to give a signal. After power is turned on, the blade of the upper limit switch 16 When it starts to rotate, the blade encounters resistance and gives a signal. Its function is to prevent the material in the hopper 9 from overflowing. Through the detection of the material level switch, the material level can be accurately given, thereby effectively avoiding the occurrence of such situations. The lower limit material switch 17 is connected to a normally closed state, that is, it gives a signal when there is no material. After power is turned on, it starts to work, and the blade of the lower limit material switch 17 starts to rotate, but the blade is always in the material state. When the material resistance is eliminated, the switch gives a signal. Its function is to prevent the hopper 9 from having no material and affecting the normal unloading into the silo.

[0022] The working principle of the utility model is:

[0023] When in use, the servo motor 14 drives the small gear 13 to rotate, and the small gear 13 drives the rotating shaft 6 to rotate by meshing with the large gear 12. The rotating shaft 6 drives the hopper 9 to rotate through the turntable 7 and the fixed frame 8, and then drives the guide plate 11 to rotate. When the guide plate 11 rotates to above the material pipe 3, the unloading valve 10 is opened, and the material is discharged from the bottom of the hopper 9 onto the guide plate 11, and then discharged from the lower end of the guide plate 11 into the material pipe 3, and then enters the corresponding silo. Such cyclic rotation can realize cyclic unloading of different silos without manual assistance, saving time and effort, and making unloading more efficient. When the lower limit material switch 17 detects that the material level in the hopper 9 is too low, the material level controller controls the feeder 15 to automatically load the material. When the upper limit material switch 16 detects that the material level in the hopper 9 is too high, the material level controller controls the feeder 15 to close and stop loading the material.
