CENTRIFUGAL SEPARATOR Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: spiral separation channel is formed by upper and lower semicylinders located opposite to each other. Dust bleed slots are located between the adjacent edges of the semicylinders. The radius of each upper semicylinder is equal to half the sum of the radiuses of two lower semicylinders adjacent to it. The channel depth is equal to the depth of an inlet branch pipe, the ratio of the channel width to its depth is no less than 5. The geometrical axis of the upper semicylinders is displaced in the horizontal plane relative to the axis of the lower semicylinders by a value no less than 0.5 of the channel depth, and the cross section area ratio of the inlet branch pipe and the outlet branch pipe is equal to 1:(3-5). EFFECT: improved structure. 7 dwg
