Abstract
As a particularly simple and compact metering apparatus for the continuous gravimetric metering of pourable material it is suggested to form a rotor (5) driven about a vertical rotational axis (4) and supported about a horizontal pivot axis (7) as a disk-type smooth-plane measuring disk and to arrange in the discharge region (6) a stripping-off element (10) extending over the radius of the measuring disk (9). In a preferred embodiment of the invention the pivot axis (7) extends - seen in plan view - centrally through the charge tunnel (3) and the stripping-off element (10).
Claims12
Metering apparatus for continuous gravimetric metering of pourable material, comprising:
- a rotor driven about a vertical rotational axis;
- a charge tunnel discharging pourable material onto the rotor;
- a discharge region, for removing said pourable material from the rotor, offset in a rotational direction to said charge tunnel;
- said rotor being supported pivotably about an essentially horizontal pivot axis and being connected to a force measuring device arranged at distance from said pivot axis;
- said rotor formed as a non-flexible disk-type, smooth-plane measuring disk;
- a stripping-off element provided in said discharge region and extending longitudinal over a radius of said measuring disk;
- and
- said horizontal pivot axis intersects said stripping-off element at a longitudinal center thereof.
