Title (EN) A SAMPLING DEVICE
(FR) DISPOSITIF D"ECHANTILLONNAGE
Abstract: front page image
(EN)A device for taking from a flowing suspension a sample-flow representative of said suspension comprises a first chamber (18) arranged to receive the flowing suspension, said first chamber communicating via a weir (23) with the upper part of a second chamber (22) having first and second openings (25, 26) arranged at the bottom thereof for removing the sample-flow and the remaining part of said suspension respectively. The openings (25, 26) are separated from each other by partition walls (27) which extend transversely of the weir over the whole length of the second chamber and communicate with a respective outlet (15, 20; 21). The openings (26) for receiving the said remaining part of the suspension communicate with the associated outlet (21) via a substantially U-shaped passage and a second weir (29) which is located substantially on the same level as the weir (23) of the first chamber. In order to prevent blockage of the U-shaped passage while maintaining requisite precision of the device, at least one of said partition walls (27) exhibits means for maintaining communication between said U-shaped passage and the sample-flow outlet (15, 20) in a region located beneath the uppermost level (33) of the connection (30) between the two legs of the U-shaped passage.
(FR)Un dispositif pour prelever depuis une suspension en ecoulement un echantillon representatif de cette suspension comprend une premiere chambre (18) concue pour recevoir la suspension, ladite premiere chambre communiquant via un deversoir (23) avec la partie superieure d"une seconde chambre (22) ayant une premiere et une seconde ouvertures (25, 26) disposees dans son fond pour retirer l"echantillon et la partie restante de ladite suspension, respectivement. Les ouvertures (25, 26) sont separees l"une de l"autre par des cloisons de separation (27) qui s"etendent transversalement par rapport au deversoir sur toute la longueur de la seconde chambre et communiquent avec une sortie respective (15, 20; 21). Les ouvertures (26) qui recoivent ladite partie restante de la suspension communiquent avec la sortie associee (21) via un passage sensiblement en U et un second deversoir (29) qui est situe sensiblement au meme niveau que le deversoir (23) de la premiere chambre. De maniere a eviter l"obstruction du passage en U tout en maintenant la precision requise du dispositif, au moins l"une desdites cloisons de separation (27) possede des moyens pour maintenir la communication entre ledit passage en U et la sortie d"echantillon (15, 20) dans une region situee sous le niveau le plus eleve (33) de la connection (30) entre les deux branches du passage en U.
