The invention relates to a device for delivering thick matter. The device comprises: a delivery cylinder (20); a material feed space (16), which is connected to the delivery cylinder (20) on the entry side; a delivery line (18), which is connected to the delivery cylinder (20) on the exit side; a delivery plunger (12), which can be displaced to-and-fro through the material feed space (16) and the delivery cylinder (20), and; a closing element (22), which is placed at the exit location of the delivery cylinder (20) or inside the delivery line (18) and which can be displaced between an open position and a closing position. In order to be able to separate foreign substances, which are contained in the flow of thick matter, out of the flow of thick matter before the actual processing step for the useful substances, the invention provides that the delivery cylinder (20) is perforated at least over a portion of its cylinder jacket (24). These measures make it possible to obtain a device that combines the features of a thick matter pump, a sieve and a press.
Dispositif de transport de matière consistante, qui comporte un cylindre de refoulement (20), une chambre d'alimentation en matière (16) raccordée au cylindre de refoulement (20) du côté de l'entrée, une conduite de transport (18) raccordée au cylindre de refoulement (20) du côté de la sortie, un piston d'alimentation (12) pouvant effectuer un mouvement de va-et-vient dans la chambre d'alimentation en matière (16) et le cylindre de refoulement (20) et un organe de fermeture (22) placé à la sortie du cylindre de refoulement (20) ou dans la conduite de transport (18) et pouvant être déplacé entre une position d'ouverture et une position de fermeture. L'objet de la présente invention est de séparer du flux de matière consistante les matières étrangères contenues dans ledit flux avant la phase de traitement proprement dite des matières utiles. A cet effet, le cylindre de refoulement (20) est perforé sur au moins une partie de son enveloppe (24). Cette configuration permet d'obtenir un dispositif qui combine les propriétés d'une pompe à matière consistante, d'un tamis et d'une presse.
