| 摘要 |
The invention relates to a measuring device for pneumatically conveyed non-uniform substances, which, in order to increase measuring accuracy and to achieve a sturdy structure with a small cross section, has a vertical removal pipe (1), which is transversely mounted by means of bearings (4, 5) in a horizontal conveying pipe (2), through which the substance (3) flows. The removal pipe (1) has a plurality of collection and/or inlet openings (a) and an outlet and/or outflow opening (b) on the same generating and/or on the same longitudinally extending casing line, the inlet openings (a) being sealed off in the rest position by a metal sealing sheet (6) which is arranged downstream, and the removal pipe being periodically driven so as to rotate through 360 DEG by a motor (7) via a transmission system (8). As it rotates, the substance is removed through the inlet openings (a) via a blocking piece (10), the blocking piece (10) closing off the removal pipe (1) in the lower region of the latter. When the rest position of the removal pipe (1) has been reached, the substance flows out of the removal pipe (1) via an inclined surface of the blocking piece (10) through the outlet and/or outflow opening (b) and out through an inclined channel (c) of a fixed removal block (9), in which the removal pipe (1) is rotatably mounted.
