Cell wheel sluice for conveying or controlled feed of bulk material in pneumatic conveyor conduit

摘要

In the housing (1) for ventilating the upwardly rotating chambers (9) of the cell wheel (5) at least one ventilating aperture (10) is arranged in the direction of rotation (6) before the feed shaft (2). The periphery of the ventilating apertures located on the cover surface of the housing bore has a number of bulge formations (11) directed against the direction of rotation of the cell wheel. The bulge formations are wedge-shaped, the points of which face against the direction of rotation of the cell wheel. The bulge formations can also be rectangular or wave-shaped.
