Description

Technical Field

[0001] The utility model relates to the technical field of silicon ore production, in particular to a smelting furnace for silicon ore production. Background Art

[0002] Silicon ore refers to the ore entity of silicon that can be mined. Silicon ore has many varieties, is widely distributed, and its uses are the focus of people's attention. Silicon is widely used in people's daily life and industrial production. The above silicate ore is used as raw material to make water-soluble sodium silicate and water-insoluble silicon dioxide. It is also the raw material for glass, ceramics, cement, bricks and tiles. The use of silicon ore and the development of new uses have attracted more and more attention.

[0003] When silicon smelting is in progress, it is a continuous process in which the charge is continuously melted from the upper part of the furnace and sinks into the furnace for chemical reaction. Usually, personnel are required to intermittently add charge into the reaction chamber from the drop port. At the same time, the charge falls into the reaction chamber at the same time, which can easily lead to uneven smelting of the charge, affecting the smelting effect. Utility Model Content
