After a period of operation, the filter screen in the filter chamber becomes clogged with fine particles. A drive motor then rotates the central plate, causing the first and second arc-shaped plates to rotate and their positions to be reversed. This allows the filter screen, originally located in the filter chamber, to enter the slag discharge chamber, replacing the existing filter screen. Airflow is then introduced through an airflow impact pipe, which forces the clogged filter screen in the slag discharge chamber to be discharged. The filter screen accumulates in the slag collection chamber and is subsequently discharged. This process repeats automatically, eliminating the need for manual replacement of the filter screen. The design is ingenious. Attached Figure Description
