Abstract

In an industrial vacuum cleaner with bag filters are used screw wound distension elements (22) for the filter bags (20). These elements are made as relatively soft springs, which, in operation, will be compressed if filter cakes (30) are formed on the bags, as this will cause an increased air pressure at the exterior dust side of the bags. However, in return the bags will be expanded by a noticeable movement each time the cleaner is stopped, this promoting a rejection of the filter cakes. This effect may be amplified by a sudden opening of a wide valve (34) in the wall of the suction chamber (26) above the filter bags, as the springs will be then straightened out almost impact-like by the associated rapid pressure increase in this chamber.
