Abstract

Provided is a peripheral feeding and separating device of a direct current electric arc furnace for titanium slag smelting. From top to bottom, a separating mechanism is sequentially provided with a material collector (2), a blanking cup (3) with an adjustment handle (4), a round separating cone (5) and no less than one blanking port (6) annularly distributed on the round separating cone (5). The peripheral feeding and separating device has the advantages of being simple in structure, reliable to use and capable of uniformly distributing conveying materials onto a plurality of blanking points.

Description

technical field [0001] The invention relates to a material distribution device. Specifically, the invention relates to a peripheral feeding and distributing device of a DC electric arc furnace for smelting titanium slag. Background technique [0002] In the DC electric arc furnace smelting titanium slag technology, the feeding point is divided into two types: the hollow electrode feeding point and the peripheral feeding point. The quantity of peripheral feeding is generally 3-6, and it is required that each feeding point must be fed continuously, and the amount of feeding should be equal, and the ratio of reducing agent should also be considered. There is no domestic smelting of titanium slag using a material distribution device. In order to improve the thermal efficiency of the electric furnace and protect the furnace top equipment, it is necessary to use the peripheral material distribution method to feed the material into the electric furnace for smelting.
