Abstract (en)
[origin: WO2006062472A1] The invention relates to a device for collecting particles in an airflow, comprising a casing (2) with a vacuum chamber (4) arranged at the top of the casing, which vacuum chamber has a connection (10) to a vacuum source and is connected to a cyclone device (6) for separating and transporting the particles from the airflow to a collection drum (8) arranged at the bottom of the casing. Said cyclone device (6) has an inlet (11) for the particle-containing airflow and an outlet (18) leading to the collection drum (8) . A bag (22) can be attached to said outlet (18) in the collection drum (8)which has a casing (30) , which can be closed off (32) in such a way that it provides a seal against the atmosphere around such an attached bag (22) . Said vacuum chamber (4) is connected to the collection drum (8) via a duct (36) , whereby a first pressure is created in a space between the casing (30) of the collection drum and the outside of the bag, and there is a second relatively higher pressure on the inside of the bag so that a pressure difference is created, by means of which the bag (22) is pressed into contact with the walls (24) and bottom (26) of the collection drum.
