Description

Technical Field

[0001] This utility model relates to the field of metallurgical exhaust hood technology, specifically a movable furnace exhaust hood. Background Technology

[0002] The furnace fume hood is an innovative environmental protection device designed specifically to cope with the complex and ever-changing process conditions in the furnace smelting process. In the furnace smelting process, different process stages will generate smoke and dust of different sizes and in different ways, which puts forward extremely high requirements for smoke and dust collection. The furnace fume hood was developed to meet this need.

[0003] However, a search of publicly available information on existing technologies revealed that existing fume hoods typically require manual movement during the slag mixing process, which is inefficient. Furthermore, when in use, the connection between the conveying pipe and the flue is not tight enough, leaving gaps that allow some smoke and dust to leak out. Insufficient sealing further exacerbates environmental pollution. Summary of the Invention

[0004] The purpose of this utility model is to provide a movable fume hood for a shaking furnace to solve the problems mentioned in the background art.

The fume hood is fixed by the locking plug 503 and the locking socket 505, and a seal is achieved by squeezing the sealing gasket 404. The hose connection assembly 4 seals the connection between the fume hood and the flue. An external induced draft fan is connected to one end of the flue. When slag needs to be added, the induced draft fan is turned on, and the smoke and dust are discharged upward from the furnace shaking pit 102 due to low pressure. After the work is completed, the main fume hood 501 and the auxiliary moving frame 506 can be separated by unlocking for cleaning and maintenance.
