Distributor for a scroll screen centrifugal separator

A distributor for a scroll screen centrifugal separator comprising:

• a first plate;
• a second plate spaced apart from the first plate;
• at least one arm attached to at least one of the first plate and the second plate;
• at least one ring positioned adjacent the arm;
• the at least one arm and the at least one ring being positioned between the first plate and the second plate to define a labyrinth therein such that slurry received by an inlet of the distributor is passable through the labyrinth toward an outlet of the distributor for directing the slurry from the outlet to a screen assembly of a scroll screen centrifugal separator;
• wherein the at least one ring is comprised of a plurality of spaced apart rings comprising a first inner ring, a second intermediate ring, and a third outer ring,
• the first inner ring being attached to the second plate and positioned to define a first gap between a side of the first inner ring and the first plate such that the slurry is passable through the first gap as the slurry is moved from the inlet to the outlet,
• the second intermediate ring being attached to the first plate and positioned between the first and third rings, the second ring positioned to define a second gap between a side of the second ring and the second plate such that the slurry is passable through the second gap when the slurry is moved from the inlet to the outlet, and
• the third outer ring being attached to the second plate and positioned to define a third gap between a side of the third outer ring and the first plate such that the slurry is passable through the third gap as the slurry is moved from the inlet to the outlet.

A scroll screen centrifugal separator comprising:

• a housing;
• a feed conduit connected to the housing, the feed conduit having a mouth through which slurry is fed into a cavity of the housing;
• a screen assembly mounted within the cavity of the housing for driven rotation within the housing;
• a scroll assembly mounted for driven rotation within the cavity of the housing, the scroll assembly being positioned within the screen assembly, and
• a distributor positioned between the feed conduit and the scroll assembly, the distributor comprising:
• a first plate;
• a second plate spaced apart from the first plate;
• at least one arm attached to at least one of the first plate and the second plate;
• at least one ring positioned adjacent the arm;
• the at least arm and the at least one ring positioned between the first plate and the second plate to define a labyrinth therein such that the slurry received by an inlet of the distributor is passable through the labyrinth toward an outlet of the distributor for directing the slurry from the outlet to a screen assembly of a scroll screen centrifugal separator.
