Centrifugal separator with extended post

摘要

A centrifugal separator includes a separation barrel with an upper end, a lower end, a central axis, and a cylindrical wall defining a separation chamber. A spin plate extends substantially across the separation chamber adjacent to the lower end thereof. A post including a central passage extends from the spin plate along the central axis of the separation barrel. The post includes at least one opening for fluid to flow from the central passage of the post to the separation chamber. An inlet in fluid communication with the separation chamber allows solids-laden fluid to flow into the separation chamber. An outlet in fluid communication with the separation chamber allows substantially-clean fluid to flow out of the separation chamber and out of the device.

1. A centrifugal separator comprising:
a separation barrel with an upper end, a lower end, a central axis, and a circularly cylindrical axially extending wall defining a separation chamber; a spin plate extending substantially across said separation chamber adjacent to said lower end; a post comprising a central passage and extending from said spin plate Into the separation barrel and along the central axis thereof, the post defining at least one opening along the longitudinal wall thereof for allowing fluid to flow from the central passage of the post Into the separation chamber, wherein the upper end of said post is closed; an inlet in fluid communication with said separation chamber for allowing flow of a solids-laden fluid thereinto; a first conduit in fluid communication with said separation barrel for allowing flow of a substantially clean fluid out of said separation chamber; a cylindrical wall extending around the separation barrel and defining an acceptance chamber above the separation barrel and a collection chamber below the separation barrel; and a second conduit extending from a bottom of the post, and in fluid communication therewith, a top of said conduit being open such that fluid In said collection chamber can flow into the second conduit and be delivered to the separation chamber via the at least one opening along the longitudinal wall of the post.
