发明名称 A METHOD AND APPARATUS FOR CONTROLLING THE CONVEYING CONDITIONS IN A PNEUMATIC CONVEYOR PIPE LINE
摘要 The pneumatic transport system for flour is fitted with a centrifugal separator (2). The mixture of flour and air arrives by the pipe (7) which runs tangentially into the conical chamber (4) at the inlet (8). The flour falls downwards whilst the air is drawn upwards through the central pipe (11) and flows through the throttle valve (13) to the outlet duct (15). A fan in the outlet duct maintains the circulation of air through the system. This fan operates most efficiently at a constant pressure difference. This constant pressure difference is maintained by a flexible diaphragm (34) with one side exposed to the outlet pressure (21) of the centrifugal separator and the other side to the inlet pressure. Any change in this pressure difference acts on the diaphragm which actuates the throttle valve (13) to maintain a constant pressure differential.
