Abstract

A liquid collection vessel for an air and liquid vacuum system of the type incorporating an air vacuum unit coupled to the vessel for drawing air and liquid therein. The vessel includes a generally cylindrical housing having an upper region. An ingress nozzle is disposed in the upper region of the housing and is adapted for receiving air and liquid there through and into the housing in response to low pressure created by the vacuum unit coupled thereto. The ingress nozzle is further disposed angularly within the housing for discharging air and liquid into the housing in a descending, tangential flow pattern. An air intake manifold is likewise disposed within the housing and coupled to the air vacuum unit for drawing air out of the housing.

Claims

1. A liquid collection vessel for an air and liquid vacuum system incorporating an air vacuum unit coupled to said vessel for drawing air and liquid therein, said vessel comprising:

a housing having generally cylindrical interior walls;

an intake fitting disposed in an upper region of said housing adapted for receiving air and liquid into said housing in response to said air vacuum unit coupled thereto;

an air intake manifold disposed within said housing and coupled to said air vacuum unit for drawing air out of said housing; and

an angulated conduit pivotally coupled with said intake fitting, wherein said conduit is disposed internally within said housing in downward acute angularity relative to the horizontal for tangentially dispersing air and liquid along said generally cylindrical interior walls, thereby creating a circumferentially descending vortex flow pattern, whereby said vortex facilitates increases water lift efficiency therein.

2. The apparatus as set forth in claim 1 wherein said housing further includes a liquid discharge port disposed therein.

3. The apparatus as set forth in claim 2 wherein said liquid discharge port of said housing is disposed in a lower region thereof.

4. The apparatus as set forth in claim 1 wherein said air intake manifold is vertically positioned above said ingress nozzle.

5. The apparatus as set forth in claim 4 wherein said air intake manifold further includes a filter screen disposed thereacross to inhibit the intake of objects carried by air passing there through.

6. The apparatus as set forth in claim 1 wherein said housing further includes a standpipe disposed therein and wherein an upper region of said standpipe forms said air intake manifold, and where a lower region of said standpipe is coupled to said air vacuum unit.

7. The apparatus as set forth in claim 6 wherein said housing has an aperture formed in a lower region thereof for coupling said standpipe in flow communication with said air vacuum unit.

8. The apparatus as set forth in claim 1 wherein said upper region of said housing includes a generally transparent dome upstanding therefrom and facilitating the positioning of said air intake manifold therebeneath and above said ingress nozzle to allow visible observation of a liquid level contained within said housing, while permitting said intake manifold to be disposed above said liquid level within said housing.

9. The apparatus as set forth in claim 1 wherein said intake fitting is constructed with an external coupling region projecting outwardly from said housing and being adapted for removable securement to and in flow communication with a vacuum system hose to facilitate the drawing of air and liquid therein in response to the creation of vortex air flow within said housing.

10. The apparatus as set forth in claim 1 wherein said housing is constructed with at least one circumferential indentation for the structural integrity thereof.

11. The apparatus as set forth in claim 1 wherein said downward acute angularity of said conduit is on the order of 30°

from the horizontal.

12. A method of collecting liquid in a vessel in an air and liquid vacuum system, said method comprising the steps of:

forming a housing having generally cylindrical interior walls for the collection of liquid therein;

providing an air vacuum unit coupled to said housing for drawing air and liquid therein;

providing an intake fitting in an upper region of said housing for removably coupling an angulated conduit to said intake fitting;

receiving air and liquid through said intake fitting and into said housing in response to low pressure created by said air vacuum unit coupled thereto;

providing an air intake manifold within said housing and coupled to said air vacuum unit for drawing air out of said housing; and

orienting said conduit angularly within said housing for tangentially dispersing air and liquid therein in a circumferentially descending vortex flow pattern along said generally cylindrical interior walls, whereby said vortex facilitates increased water lift efficiency therein.

13. The method as set forth in claim 12 and further including the step of forming a liquid discharge orifice having a valve in a lower region of said housing for selectively eliminating the liquid collected therein.

14. The method as set forth in claim 13 and further including the step of disposing said liquid discharge orifice of said housing in a lower region thereof.

15. The method as set forth in claim 12 and further including the step of positioning said air intake manifold vertically above said intake fitting.

16. The method as set forth in claim 15 and further including the step of providing a filter screen and securing said filter screen around said air intake manifold to inhibit the intake of objects carried by air passing there through.

17. The method as set forth in claim 16 and further including the step of providing a standpipe and disposing said standpipe within said housing wherein the upper region of said standpipe forms said intake manifold and a lower region of said standpipe is coupled to said air vacuum unit.

18. The method as set forth in claim 17 and further including the step of forming on said housing an aperture in a lower region thereof, and mounting said standpipe in flow communication with said aperture in said lower region of said housing for facilitating the coupling of said standpipe to said air vacuum unit.

19. The method as set forth in claim 12 and further including the steps of constructing said upper region of said housing with an opening for facilitating the positioning of said air intake manifold therein and above said ingress nozzle, providing a transparent dome, and mounting said dome over said opening to allow for visible observation of a liquid level contained within said housing, while permitting said intake manifold to be disposed above said liquid level within said housing.

20. The method as set forth in claim 12 and further including the steps of forming on said intake fitting an external coupling region projecting outwardly from said housing and being adapted for removable securement to and in flow communication with a vacuum system hose to facilitate the drawing of air and liquid therein in response to the creation of vortex air flow from within said housing.

21. The method as set forth in claim 12 wherein said housing is formed having an indentation region molded about the perimeter of said housing for increasing the structural integrity, thereby preventing said housing to collapse during operation of said air vacuum unit.

22. The method as set forth in claim 12 wherein said step of orienting said conduit includes the step of orienting said conduit downwardly on the order of 30°

from the horizontal.
