Abstract

An apparatus for separating solid matter from a liquid stream, where the apparatus includes a generally cylindrical separation panel surrounding an interior space, which is oriented so as to have a substantially vertical longitudinal axis. The separation panel has a plurality of vertically and horizontally spaced openings which are adapted to remove solid material larger than a predetermined size from liquid passing through the separation panel. The apparatus also includes a chamber surrounding the separation panel and providing a chamber portion into which the liquid passes after passing through the separation panel. The apparatus may further include an inlet positioned below the separation panel, through which the liquid stream is delivered from a bottom opening of the separation panel to the interior space and which is arranged such that the liquid circulates about the axis so as to pass the separation panel, and an outlet extending from the chamber portion.

Claims (8)

1. An apparatus for separating solid mater from a liquid stream, the apparatus comprising:

a generally cylindrical separation panel surrounding an interior space which is oriented so as to have a substantially vertical longitudinal axis, the separation panel having a perforated section between annular upper and lower sections of the panel, wherein the perforated section comprises a plurality of vertically and horizontally spaced openings which are adapted to remove solid material larger than a predetermined size from liquid passing through the perforated section of the separation panel, and wherein the annular lower and upper sections of the separation panel do not have the vertically and horizontally spaced openings;

a chamber surrounding the separation panel and providing a chamber portion into which the liquid passes after passing through the perforated section of the separation panel, the chamber extending the full height of the separation panel and providing an annual space between an outer wall of the chamber and each of the upper section, perforated section, and lower section of the separation panel to allow liquid therein;

an inlet extending into the interior space through an opening in a wall of the annular lower section of the separation panel, the inlet coupled to the annular lower section of the separation panel through which the liquid stream is delivered to said interior space of the separation panel, wherein the liquid stream circulates about the vertical axis in the interior space and rises from the annular lower section to contact the perforated section of the separation panel;

an outlet extending from said chamber portion, the outlet being positioned above the perforation section of the separation panel so that at least a portion of said perforated section is submerged; and

a sump receptacle to receive particular matter removed from the liquid stream by the separation panel, wherein the sump receptacle is positioned below the separation panel and in fluid communication with the interior space of the separation panel,

wherein said perforated section of the separation panel has a plurality of vertically and horizontally spaced deflective segments adjacent the openings and which project inwardly with respect to said space to inhibit particulate matter of at least said predetermined size from blocking said openings by the openings being positioned behind the deflective segments relative to the flow of the liquid there passed.

2. The apparatus of claim 1 wherein the sump receptacle is in fluid communication with the interior space of the separation panel via an opening in a laterally extending wall that separates the separation panel from the sump receptacle.
