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 and inducing drag in a liquid flow, wherein the system is configured for insertion into a manhole thereby creating a sump region below the system, wherein the system comprises:
a liquid quality device comprising:
a first region having a funnel with a sump inlet aperture;
a second region having a sump outlet aperture;
a weir positioned between the first region and the second region;

a plurality of drag-inducing portions located below the liquid quality device and projecting inwardly towards a central axis of the sump region, wherein the plurality of drag-inducing portions comprise at least:
a first set of drag-inducing portions;
a second set of drag-inducing portions;
a third set of drag-inducing portions; and
wherein each of the first, second, and third, sets of drag-inducing portions are positioned equidistant from each other and at a same height around a perimeter of the sump region; and

a plate positioned in the sump region between the liquid quality device and the plurality of drag-inducing portions wherein the plate projects inwardly toward the central axis of the sump region;
wherein the funnel in the first region, the weir, and the plurality of drag-inducing portions are integrated and formed into a single piece.

2. The system of claim 1 , wherein:
the liquid quality device further comprises a fourth set of drag-inducing portions; and
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.

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

4. The system of claim 3 , 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.

5. 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.

6. 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.

7. The system of claim 1 , wherein:
the first region is configured to receive a flow of liquid from the inlet of the manhole 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 manhole.

8. The system of claim 1 , wherein the weir comprises a constant curvature along a horizontal dimension.

9. The system of claim 1 , wherein the weir comprises a varying curvature along a horizontal dimension.

10. The system of claim 1 , wherein the liquid quality device further comprises a clean-out riser pipe extending upwardly from a clean-out aperture in the second region.

11. The system of claim 1 , further comprising a plurality of supporting portions, wherein the funnel in the first region, the weir, the supporting portions, and the plurality of drag-inducing portions are integrated and formed into a single piece.

12. The system of claim 1 , wherein the plate further comprises a plurality of plates, each of the plurality of plates being positioned above each of the plurality of sets of drag-inducing portions.

13. A system for removing particulates from liquid and inducing drag in a liquid flow, wherein the system is configured for insertion into a manhole thereby creating a sump region below the system, wherein the system comprises:
a liquid quality device comprising:
a first region having a funnel with a sump inlet aperture;
a second region having a sump outlet aperture;
a weir positioned between the first region and the second region;

a plurality of drag-inducing portions located below the liquid quality device and projecting inwardly towards 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-inducing 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;

a plate positioned in the sump region between the liquid quality device and the plurality of drag-inducing portions wherein the plate 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;
wherein the funnel in the first region, the weir, and the plurality of drag-inducing portions are integrated and formed into a single piece.

14. The system of claim 13 , wherein at least one of the first, second, or third sets of drag-inducing portions further comprises:
a first tooth;
a second tooth located below the second tooth; and a third tooth located below the second tooth.

15. The system of claim 14 , 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.

16. The system of claim 13 , 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.

17. The system of claim 13 , wherein:
the first region is configured to receive a flow of liquid from the inlet of the manhole 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 manhole.

18. The system of claim 13 , wherein the liquid quality device further comprises a clean-out riser pipe extending upwardly from a clean-out aperture in the second region.

19. The system of claim 13 , further comprising a plurality of supporting portions, wherein the funnel in the first region, the weir, the supporting portions, and the plurality of drag-inducing portions are integrated and formed into a single piece.

20. The system of claim 13 , wherein the weir comprises a constant curvature along a horizontal dimension.

21. The system of claim 13 , wherein the weir comprises a varying curvature along a horizontal dimension.

22. The system of claim 13 , wherein an orientation and an angle of the at least one drag-inducing portions are adjustable.
