A screw press provided with a rear excess fluid outlet is described herein. The rear excess fluid outlet includes a circular screen (30) provided at a longitudinal end of the screw press body, near a material inlet. Scraper blade assemblies (34) are provided to prevent the screen (30) from clogging. The efficiency of excess fluid removal is thereby increased by the increased screen surface near the material inlet of the screw press. (See formula) For two-letter codes and other abbreviations, refer to the "Guid- ance Notes on Codes and Abbreviations"appearing at the begin- ning of each regular issue of the PCT Gazette.
La présente invention concerne une presse à vis, pourvue d'une sortie arrière pour l'excès de liquide. Cette sortie arrière pour excès de liquide comprend une grille circulaire (30), qui est montée à une extrémité longitudinale du corps de la presse à vis, à proximité d'une entrée de matière. Des ensembles lames racleuses (34) permettent d'empêcher l'obstruction de la grille (30). L'augmentation de la surface de grille à proximité de l'entrée de matière de la presse à vis permet d'améliorer le rendement d'élimination de l'excès de liquide.
