Abstract
Appareil de séparation sélective de particules d'un mélange de liquides et de solides contenant des particules solides de dimensions et de poids divers. Il comporte un conduit permettant l'introduction du mélange dans une chambre cylindrique à l'intérieur de laquelle tourne un cylindre perforé. Un deuxième conduit permet au trop-plein du mélange, contenant de fines particules solides, de s'écouler, et un troisième conduit permet à un courant inférieur du liquide, contenant des particules solides plus grosses, de s'écouler également. Une duse réglable communique avec au moins l'un des deuxième et troisième conduits afin de permettre un réglage sélectif des débits d'écoulement du trop-plein et du courant inférieur. Domaine d'application : épuration des fluides de forage.Apparatus for the selective separation of particles from a mixture of liquids and solids containing solid particles of various sizes and weights. It comprises a conduit allowing the introduction of the mixture into a cylindrical chamber inside which a perforated cylinder rotates. A second conduit allows the overflow of the mixture, containing fine solid particles, to flow, and a third conduit allows a lower stream of the liquid, containing larger solid particles, to flow as well. An adjustable choke communicates with at least one of the second and third conduits to allow selective adjustment of the overflow and underflow flow rates. Field of application: purification of drilling fluids.
