The inverted cone cyclone dust remover makes use of the inlet wind to enter the dust remover along the tangent direction and rotate along the cylinder wall. By the action of Centrifugal Force, the dust particles gradually settle into the lower ash head of the dust remover. The body enters the next-stage dust collector along the air outlet at the upper part of the dust collector, and the dust in the ash head is discharged periodically by the ash discharge door.
