Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The external power supply of the feeding mechanism 2 is switched on, the feeding mechanism 2 starts to work to feed, the flue gas generated by the blast furnace carries mineral dust to enter a filter bin 5 through an air inlet pipe 6, the airflow pushes a scraper blade 9 to rotate around a bearing through a rotating shaft 7, the flue gas passes through a screen mesh 10 and is discharged through an air outlet pipe 4, the smoke dust is blocked and filtered out by the screen mesh 10, the scraper blade 9 rotates to scrape and clean the screen mesh 10, the scraper blade 9 is an arc-shaped mechanism, the smoke dust is scraped towards the middle and gathered through the centripetal force action of the arc-shaped structure, the smoke dust drops downwards under the action of gravity after being gathered to a certain amount, the rotating shaft 7 drives an arc-shaped plate 8 to rotate, the arc-shaped deflection direction of the arc-shaped plate 8 is opposite to the deflection direction of the scraper blade 9, so that the smoke dust is pushed to move through the radian of the arc-shaped plate 8, and the smoke dust is gathered at one side of a collection bin 3 under the action of centrifugal force, after long-time use, the cabin door of the collecting cabin 3 is opened to treat the smoke.
