ABSTRACT:
The filter assembly consists of a plurality of filter cartridges (30) each including a supporting ring (32) and a filter hose (36) connected to the same. At the end remote from the supporting ring (32) they are closed by a dish-like deflecting member (40). Each filter cartridge (30) contains an immersion tube (56) arranged coaxially with the filter hose (36) and terminating slightly spaced from a central bottom portion of the deflecting member (40). The immersion tube (56) is connected to a gas conduit (46) by means of which a gas may be introduced. Together with a piston (84) guided in the immersion tube (56) and at least one spring (34;88) the deflecting member (40) constitutes a system which is adapted to vibrate and periodically tightens the filter hose (36). In this manner the filter hose (36) may be cleaned of dust both thoroughly and carefully.
