Cyclone dust analyzer for determining microdust content in fibers |
摘要 |
An apparatus for removing dust from a fiber sample for subsequent analysis is disclosed. A first upper cylindrical chamber containing a fiber sample has a tangential air jet and a radial air jet installed to swirl and tumble the fiber sample in a cyclonic fashion, thus liberating the dust from the sample when either a positive or a negative pressure is applied through the air jets. The liberated dust particles are then screened out through a 100 mesh screen filter and exhausted through a funnel. The device can be equipped with a second stage chamber containing a plurality of step-stage filters and a third stage plurality of microfilters to selectively screen the dust particles. A blow bottle containing an aqueous medium to absorb even the finest dust particles or gas can also be added as a fourth stage.
