[0002] A smelting electric furnace is a device that uses electric energy for smelting. Its main working principle is to heat the metal material to above its melting point through resistance heating, thereby achieving the purpose of smelting.

[0003] At present, there are many ways and devices for feeding smelting electric furnaces, such as feeding with a basket. The feeding process is to load the charge into a basket with an iron chain pinned at the bottom according to certain requirements. When feeding, first lift the furnace cover, then use a crane to lift the basket from the top of the furnace into the furnace, and then pull the pin to unload the charge into the furnace. However, when the charge enters the furnace body, it is easy to form a conical pile of charge in the center of the furnace body, which cannot meet the requirement of uniform feeding in the smelting electric furnace, resulting in uneven heating of the charge in the electric furnace and increased power consumption. In view of this, we propose a feeding device for smelting electric furnaces. Utility Model Content

The multi-stage hydraulic cylinder 301 is provided with two groups. The movable end of the multi-stage hydraulic cylinder 301 is connected to a movable ring plate 302, and a barrel 303 is clamped inside the movable ring plate 302, wherein the movable ring plate 302 and the barrel 303 are fixedly connected, and the movable ring plate 302 forms a lifting structure with the supporting ring plate 2 through the multi-stage hydraulic cylinder 301, and a plurality of discharge pipes 304 are provided at the bottom of the barrel 303. Furthermore, the discharge pipes 304 are bent, and the plurality of discharge pipes 304 are evenly distributed in a ring shape at the bottom of the barrel 303. The utility model uses a multi-stage hydraulic cylinder 301 to effectively drive the movable ring plate 302 to move downward, so that the feed tube 304 enters the interior of the electric furnace body 1, and then the charge is poured into the barrel 303. The charge is evenly discharged through the feed tube 304 evenly distributed in an annular shape at the bottom of the barrel 303, and the charge is evenly fed to all directions of the electric furnace body 1, thereby avoiding increased power consumption caused by uneven heating of the charge.

[0025] It is worth noting that the auxiliary mechanism 4 includes a bracket 401, which is fixed to the middle end of the bottom of the barrel 303.
