| 摘要 |
The invention refers to a feeder device for the output of flowing material from a tank. The feeder device contains a housing (1) with an intake part (2) and an outflow part (3). An axel (4) is attached into the housing (1), which is supported with by a pocket-equipped rotor (7) with an axial channel (5) and a radial channel (6), whose channels are connected with a source for compressed gas. The axel (4) supports around this a rotary gas-diverting valve (10) with a ring-shaped cavity (12), which by means of radial partitions (13) is divided into mutually separated sections (14) with different dimensions. The wall of the intake part (2) is equipped with a large number of holes (15), which are connected to each other via a main canal (17) and with that of the sections (14) of the sliding valve's (10) cavity (12), which is connected with the axle's (4) radial canal (6).<IMAGE> |
