Technical Field

[0001] The utility model relates to the technical field of sponge iron canning, in particular to an iron scale material guiding device for sponge iron canning. Background Art

[0002] Sponge iron, also known as direct reduced iron, is mainly used to replace scrap steel in electric furnace steelmaking. When filling sponge iron cans, a soft material pipe is generally used to load the silicon carbide cans on the kiln car table. When filling iron scale, it is necessary to guide the material, so a sponge iron can iron scale guiding device is needed.

After the iron scale canning is completed, the staff needs to remove the guiding hopper for the next canning work. The excess material inside the guiding hopper cannot be recovered when it is removed and will be directly discharged to the outside, thus causing waste. Utility Model Content

When canning is required, the driving mechanism drives the blocking plate assembly to rotate a certain angle so that the blocking plate avoids the blanking hole, and then the iron scale is poured into the guide hopper. After the iron-phosphorus tank filling cavity is full, the driving mechanism drives the blocking plate assembly to rotate again so that the blocking plate blocks the blanking hole, thereby storing the excess iron scale in the guide hopper.

[0008] As an optimization, the driving mechanism includes a stepping motor, and the rotation of the blocking plate assembly is achieved by the stepping motor.

In this solution, the rotating shaft of the stepper motor drives all the blocking plates to rotate through the connecting rod.

[0014] As an optimization, the feeding mechanism further comprises a feeding hopper located at the upper end of the feeding tube, and the feeding hopper is fixedly connected to the feeding tube through a connecting block. The feeding hopper in this solution facilitates the filling of materials in the outer ring of the feeding tube.

[0015] As an optimization, the inner tube is fixedly connected to the feed tube via a plurality of circumferentially arranged connection plates. The connection plates in this solution realize the fixed connection between the inner tube and the feed tube.
