Description

Technical Field

[0001] The utility model relates to the technical field of industrial silicon smelting, in particular to a smoke hood used for a metallic silicon smelting furnace. Background Art

[0002] Industrial silicon is also called metallic silicon. The main component silicon element content is about 98%, and the remaining impurities are iron, aluminum, calcium, etc. When industrial silicon is produced and processed, a smelting furnace is needed for auxiliary operations. The smelting furnace is needed in the process of industrial silicon smelting. The smelting furnace exhausts smoke through a chimney, and a smoke hood is installed on the chimney.

[0003] For example, the utility model patent with application number 202222442705.1 discloses a smoke hood for a metal silicon smelting furnace, including a hood body and a mounting ring, a gear ring slidably connected to both the hood body and the mounting ring is arranged between the hood body and the mounting ring, a T-shaped limit ring rotatably connected to a T-shaped ring groove provided inside the hood body is fixedly connected at the upper end of the gear ring, a motor fixedly connected to the hood body through a fixed rod is arranged on one side of the hood body, a rotating gear meshingly connected to the gear ring is fixedly connected to the output end of the motor through a rotating shaft, a scraper slidably connected to the inner surface of the hood body is arranged inside the hood body, a mounting block fixedly connected to the inner surface of the gear ring is fixedly connected at the lower end of the scraper, and a circular mounting hood is fixedly connected at the lower end of the mounting ring.
