Vorrichtung zum Bewegen und Behandeln von Teilchen

The apparatus having a downwardly opening filter housing (12) and including multiple processing gas outlets (28) and partition means dividing the interior of the filter housing (12) into individual downwardly-opening open-bottom compartments (22, 24) equal in number to the gas outlets (28). The partition means extends into a chamber (14) that is positioned below the filter housing (12) and serves for accommodating the particles to be moved and treated. Each gas outlet (12) is associated with a filter cartridge (70) that is disposed in the corresponding compartment (22, 24) and can filter the processing gas. Each gas outlet (28) is operatively associated with an on/off valve which may be individually opened and closed. Additionally, each gas outlet (28) and filter cartridge (70) has a cleaning gas supply structure operatively associated therewith so that cleaning gas under pressure my be supplied to the interior of a filter cartridge (70) for cleaning the same when the associated on/off valve is closed. Thus, the filter cartridges (70) can be cleaned simply and effectively by means that can be provided at low costs.
