Abstract
A device for taking test samples from a fluid material including passing the material gravitationally downwardly through a first chamber and through a sample divider plate having a plurality of radially extending openings with a sample takeoff passage receiving a sample through one of the openings and directing the sample to a second chamber which is provided with a second sample divider plate also having openings and with a second sample takeoff receiving a sample from one of the openings and directing it to a third chamber having a sample divider with a plurality of openings and taking a sample through one of said openings with a third sample takeoff passage.
Claims10
A mechanism for continuously obtaining a representative sample from a fluid material such as from sludges or pulps comprising in combination:
- a circular chamber with an inlet opening and a main discharge opening;
- a sample divider in the chamber having a plurality of sample openings uniformly distributed circumferentially;
- said inlet opening discharging tangentially into the upper end of said chamber and creating a whirling circular motion in the material in the chamber so that the material has rotary turbulence in passing said sample openings;
- and
- a sample takeoff passage connected to at least one of said sample divider openings for a sample flow with the remaining flow through the chamber passing through the unconnected sample divider openings to said main discharge opening.
