Title (EN) METHOD OF SEPARATING A SOLID AND A LIQUID PHASE OF A MASS
(FR) METHODE DE SEPARATION DES PHASES SOLIDES ET LIQUIDES D"UNE MASSE
Abstract:
(EN) This specification describes a method of separating a fine-grained close-packed solid material from a liquid with which the fine-grained material is saturated. The material may by way of example consist of grindings; metal-containing pickling bath deposits; or metal oxides from metallurgical venturi-filter. The most mixture (1) is packed in a container (2) which thereafter is closed and heated from underneath. The liquid is evaporated starting from the lower portions in the container and forces liquid from the upper portions towards the surface of the paste-like mixture, wherefrom collected liquid (9) can be removed. Common oil drums can be used as containers. When the liquid has been removed the containers with enclosures can be charged in metallurgical furnaces or can the material be dumped together with waste material without any effects detrimental to the environment.
(FR) Il est decrit une methode de separation d"un materiau solide en particules de granulometrie fine et de consistance compacte a partir d"un liquide sature par ce materiau. Celui.ci peut par exemple consister en des dechets de meulage, des residus de bain de decapage contenant du metal ou des oxydes metalliques provenant de filtres venturo metallurgiques. Le melange humide (1) est tasse dans un recipient (2) lequel est ensuite ferme et chauffe par en dessous. Le liquide est evapore a partir de la partie inferieure du recipient et propulse le liquide des parties superieures vers la surface de la masse pateuse d"ou le liquide (9) recueilli peut etre retire. Des futs a huile de type courant peuvent etre utilises comme recipients. Lorsque le liquide a ete retire les recipients et leurs contenus peuvent etre charges dans un four metallurgique. Le materiel peut aussi etre mis au rebut avec d"autres materiaux et cela sans dommage pour l"environnement.
