CENTRIFUGE Russian patent published in 2022 - IPC B04B1/14 B04B7/12 

FIELD: separation.

SUBSTANCE: invention relates to a centrifuge, in which a fluid initial product can be purified from solid substances during continuous operation in a centrifugal field in a rotating drum, wherein the drum has an upper drum part and a lower drum part, wherein the upper drum part or the lower drum part has a movable piston slide valve, by means of which outlet holes in the drum can be opened or closed, besides, one or more wear-protective elements are provided for protection against abrasive wear. At that, a) the drum has two or more first wear-protective elements on the axial annular surface of the upper part of the drum or the lower part of the drum, wherein the wear-protective elements are in the form of circular annular segments, b) the piston slide has two or more second wear-protective elements on the corresponding axial annular surface, wherein wear-protective elements have the form of circular annular segments, c) wherein each of the wear-protective elements together with one or two corresponding adjacent wear-protective elements has a corresponding butt edge with formation of a gap between the adjacent butt edges.

EFFECT: creation of additional structural methods of protection of elements of centrifuge drum and on this drum from abrasive wear.
