Abstract
The present invention relates to a property determining apparatus for automatically determining in real time, properties of a slurry material such as of a sludge under treatment. The apparatus, being provided with a sampling cylinder 2, a quantitative sampling piston pair comprised of a rear piston 3 and a front piston 4, an air cylinder 5, a measurement tank 8, and a measuring means 10, is connected to a transfer pipe P and the like for a slurry material via a connecting opening 2w of the sampling cylinder 2. As a measuring operation, slurry material is first collected into the sampling cylinder 2 by a volume corresponding to the space S of the pistons 3,4 when the quantitative sampling piston pair is retracted from an initial position shown with a two-dot chain line, supplied to the measurement tank 8 when the space between the pistons are narrowed, then the properties of a slurry material is measured with the measuring means 10, and after that, the space of the pistons are returned to an original position so as to return the slurry material from the measurement tank into the sampling cylinder, and finally the quantitative sampling piston pair is returned to the original position…
