HYDRAULIC MULTICLONE Russian patent published in 2000 - IPC

FIELD: separation of liquid nonhomogeneous media under action of centrifugal forces; chemical, petroleum refining, mining and other industries. SUBSTANCE: proposed hydraulic multiclone includes coarse cleaning hydraulic cyclone and fine cleaning hydraulic cyclone. Multiclone has sand branch pipe cleaning unit made in form of hydraulic cylinder filled with flushing liquid and fixed on sand branch pipe; it is provided with valves located in through passage connected with hole of sand branch pipe and brought into communication with working space of hydraulic cylinder whose piston performs motion towards branch pipe; valves connected with hydraulic cylinder by means of holes open in anti-phase. Axis of hydraulic cylinder nay be perpendicular relative to axis of sand branch pipe. Valves are made in form of spring-loaded fluoroplastic balls. Diameter of through passage exceeds diameter of sand branch pipe by 2 to 3 times. EFFECT: enhanced reliability due to reduced hole cleaning time. 4 cl, 2 dwg
