Title:
個別に駆動されるインパクタープレートを備えるカスケード式インパクター
Document Type and Number:
Japanese Patent JP4519842
Kind Code:
B2
Abstract:
A cascade impactor apparatus has a series of vertically stacked impactor housing sections. Each of the impactor housing sections has an upper portion that supports a motor for driving an impactor plate that is positioned below a nozzle through which flow passes. Each housing section also has an outlet passageway leading to a lower impactor chamber for the next in a series of impactor chambers, except the last outlet passageway is coming through a filter to exhaust. The impactor chambers are defined by a skirt that seals on the neck of the next downstream housing section. The impactor plates are each driven by a separate motor, and held onto a hub on the motor output shaft with a magnetic coupling so the plates can be removed when the housings are separated.
