Background Art

Smelting is a pyrometallurgical process in which metal materials and other auxiliary materials are put into a heating furnace to melt and temper. The materials in the high-temperature furnace undergo certain physical and chemical changes to produce crude metal or metal enrichment and slag.

During the smelting process, after the aluminum liquid is used, the aluminum liquid level drops. There are currently two ways to add aluminum ingots. One is the manual addition method, which is time-consuming and labor-intensive, and due to the high temperature in the smelting furnace, there is a risk of scalding when adding aluminum ingots; the second is to add materials by setting an automatic falling feeding device on the top of the smelting furnace. For example, the patent with application number CN201420265921.6 discloses a feeding device, which includes a base, a lifting cylinder is fixedly arranged on the upper part of the base, a rotating motor is fixedly arranged on the upper part of the lifting cylinder, a rotating shaft is fixedly arranged on the upper part of the rotating motor, a moving frame is slidably connected to the upper part of the rotating shaft, and the two ends of the moving frame are respectively connected to the middle axis of the roller, and the rollers are connected by a feeding belt.
