Abstract

The embodiments of the present disclosure provide a system for removing particulates from liquid. The system may comprise a base, a tubular body extending upwardly from the base, a liquid quality device located above the base, a sump region located between the base and the liquid quality device, and a plurality of drag-inducing portions positioned in the sump region and projecting inwardly toward a central axis of the sump region. The tubular body may comprise an inlet and an outlet. The plurality of drag-inducing portions may comprise a first set of drag-inducing portions, a second set of drag-inducing portions, a third set of drag-inducing portions, and a fourth set of drag-inducing portions. The first, second, third, and fourth sets of drag-inducing portions may be positioned equidistant from each other and at a same height around a perimeter of the sump region.

First claim

What is claimed is:

1. A system for removing particulates from liquid, comprising:
a base;
a tubular body extending upwardly from the base, wherein the tubular body comprises an inlet and an outlet;
a liquid quality device located above the base wherein the liquid quality device comprises:
a first region comprising a funnel with a sump inlet aperture;
a second region comprising a sump outlet aperture; and
a weir positioned between the first region and the second region;

a sump region located between the base and the liquid quality device;
a plate positioned in the sump region between the liquid quality device and the plurality of drag-inducing portions, wherein the plate is attached to an internal surface of the tubular body and projects inwardly toward the central axis of the sump region; and
a plurality of drag-inducing portions positioned in the sump region and projecting inwardly toward a central axis of the sump region, wherein the plurality of drag-inducing portions comprise:
a first set of drag-inducing portions;
a second set of drag-inducing portions;
a third set of drag-inducting portions; and
a fourth set of drag-inducing portions,
wherein the first, second, third, and fourth sets of drag-inducing portions are positioned equidistant from each other and at a same height around a perimeter of the sump region.

2. The system of claim 1 , wherein the plate projects inwardly toward the central axis of the sump region such that the plate partially covers a horizontal, cross-sectional area of the sump region.

3. The system of claim 1 , further comprising:
a tube positioned below the sump inlet aperture, wherein the tube extends downwardly from the sump inlet aperture into the sump region.

4. The system of claim 1 , wherein:
the first region is configured to receive a flow of liquid from the inlet of the tubular body and transfer the flow of liquid through the sump inlet aperture of the funnel and into the sump region, and
the second region is configured to receive the flow of liquid from the sump region through the sump outlet aperture and transfer the flow of liquid to the outlet of the tubular body.

5. The system of claim 1 , wherein at least one of the first, second, third, or fourth sets of drag-inducing portions further comprises:
a first tooth;
a second tooth located below the first tooth;
and a third tooth located below the second tooth.

6. The system of claim 5 , wherein teeth of the first set of drag-inducing portions are positioned in a different orientation than teeth of the second set of drag-inducing portions.

7. The system of claim 1 , wherein the first, second, third, and fourth sets of drag-inducing portions are attached to respective supporting portions positioned proximate the tubular body in the sump region.

8. A system for removing particulates from liquid, comprising:
a base;
a tubular body extending upwardly from the base, wherein the tubular body comprises an inlet and an outlet;
a liquid quality device located above the base, wherein the liquid quality device comprises:
a first region comprising a funnel with a sump inlet aperture;
a second region comprising a sump outlet aperture; and
a weir positioned between the first region and the second region;

a sump region located between the base and the liquid quality device;
a plurality of drag-inducing portions positioned in the sump region and projecting inwardly toward a central axis of the sump region;
a plate positioned in the sump region between the liquid quality device and the plurality of drag-inducing portions wherein the plate is attached to an internal surface of the tubular body and projects inwardly toward the central axis of the sump region; and
a tube positioned below the sump inlet aperture, wherein the tube extends downwardly from the sump inlet aperture into the sump region.

9. The system of claim 8 , wherein the plurality of drag-inducing portions comprise:
a first set of drag-inducing portions;
a second set of drag-inducing portions;
a third set of drag-inducting portions; and
a fourth set of drag-inducing portions,
wherein the first, second, third, and fourth sets of drag-inducing portions are positioned equidistant from each other and at a same height around a perimeter of the sump region.

10. The system of claim 9 , wherein at least one of the first, second, third, or fourth sets of drag-inducing portions further comprises:
a first tooth;
a second tooth located below the first tooth;
and a third tooth located below the second tooth.

11. The system of claim 10 , wherein teeth of the first set of drag-inducing portions are positioned in a different orientation than teeth of the second set of drag-inducing portions.

12. The system of claim 9 , wherein the first, second, third, and fourth sets of drag-inducing portions are attached to respective supporting portions positioned proximate the tubular body in the sump region.

13. The system of claim 8 , wherein the plate projects inwardly toward the central axis of the sump region such that the plate partially covers a horizontal, cross-sectional area of the sump region.

14. The system of claim 8 , wherein:
the first region is configured to receive a flow of liquid from the inlet of the tubular body and transfer the flow of liquid through the sump inlet aperture of the funnel and into the sump region, and
the second region is configured to receive the flow of liquid from the sump region through the sump outlet aperture and transfer the flow of liquid to the outlet of the tubular body.

15. The system of claim 8 , wherein the tube is configured to extend between about 2 inches and about 20 inches downwardly from the sump inlet aperture into the sump region.

16. A system for removing particulates from liquid, comprising:
a base;
a tubular body extending upwardly from the base, wherein the tubular body comprises an inlet and an outlet;
a liquid quality device located above the base, wherein the liquid quality device comprises:
a first region comprising a funnel with a sump inlet aperture;
a second region comprising a sump outlet aperture; and
a weir positioned between the first region and the second region;

a sump region located between the base and the liquid quality device;
a plurality of sets of drag-inducing portions positioned equidistant from each other and at a same height around a perimeter of the sump region;
a plate positioned in the sump region between the liquid quality device and the plurality of sets of drag-inducing portions wherein the plate is attached to an internal surface of the tubular body and projects inwardly toward the central axis of the sump region; and
a tube positioned below the sump inlet aperture, wherein the tube extends downwardly from the sump inlet aperture into the sump region.
