Abstract

A wash ring for cleaning a tank. The wash ring comprises a curved surface having an inner edge and an outer edge. The wash ring further comprises an inner wall having a first height and an outer wall located between the inner end and outer end and having a second height that is less than the first height. A plurality of notches is located at the outer edge of the curved surface. The wash ring has a feed pipe with an outlet located between the inner wall and outer wall.

First claim

The invention claimed is:

1. An apparatus comprising:
a curved surface having an inner edge and an outer edge;
an inner wall having a first height located at the inner edge of the curved surface;
an outer wall located between the inner edge and outer edge of the curved surface and having a second height that is less than the first height;
a plurality of notches located at the outer edge of the curved surface; and
a feed pipe having an outlet located between the inner wall and outer wall.

2. The apparatus set forth in claim 1 , wherein the outer edge of the curved surface is shaped to abut against an inner tank wall.

3. The apparatus set forth in claim 1 , wherein the curved surface has a constant radius.

4. The apparatus set forth in claim 1 , further comprising:
wherein the curved surface is less than 360 degrees and having first and second ends;
a first end cap located at the first end; and
a second end cap located at the second end.

5. The apparatus set forth in claim 4 , wherein the curved surface is semi-circular.

6. The apparatus set forth in claim 4 , further comprising a first flange extending from the first end having a first mounting hole.

7. The apparatus set forth in claim 6 , further comprising a second flange extending from the second end having a second mounting hole.

8. The apparatus set forth in claim 1 , further comprising a second feed pipe having an outlet located between the inner wall and outer wall.

9. The apparatus set forth in claim 1 , wherein the feed pipe further comprises a plurality of feed pipes.

10. The apparatus set forth in claim 1 , further comprising a L-shaped bracket coupled with the inner wall and a lip of a tank.

11. The apparatus set forth in claim 10 , further comprising a support bracket coupling the inner wall to an inner wall of the tank.

12. An apparatus, comprising:
a first semi-circular, curved surface that comprises:
a first inner edge, and a first outer edge,
a first end and a second end,
a first end cap at the first end of the first semi-circular, curved surface,
a second end cap at the second end of the first semi-circular, curved surface,
a first inner wall having a first height,
a first outer wall located between the first inner edge and the first outer edge and having a second height that is less than the first height,
a first plurality of notches located at the first outer edge of the first curved surface, and
a first feed pipe having an outlet located between the first inner wall and the first outer wall;

a second semi-circular, curved surface that comprises:
a second inner edge and a second outer edge,
a first end and a second end,
a first end cap at the first end of the second semi-circular, curved surface,
a second end cap at the second end of the second semi-circular, curved surface,
a second inner wall having a third height,
a second outer wall located between the first inner edge and the first outer edge and having a fourth height that is less than the third height,
a second plurality of notches located at the outer edge of the curved surface, and
a second feed pipe having an outlet located between the second inner wall and the second outer wall;

wherein the first and second curved surfaces are shaped to abut against an inner tank wall;
a first flange extending from the first end of the first semi-circular, curved surface having a first mounting hole;
a second flange extending from the second end of the first semi-circular, curved surface, having a second mounting hole;
a third flange extending from the first end of the second semi-circular, curved surface having a third mounting hole positioned to mate with the first mounting hole;
a fourth flange extending from the second end of the second semi-circular, curved surface having a fourth mounting hole positioned to mate with the second mounting hole;
a first fastener passing through the first mounting hole and second mounting hole coupling the first flange with the third flange; and
a second fastener passing through the second mounting hole and the fourth mounting hole coupling the first flange with the fourth flange.

13. The apparatus set forth in claim 12 , further comprising a third feed pipe having an outlet located between the first inner wall and first outer wall.

14. The apparatus set forth in claim 13 , further comprising a fourth feed pipe having an outlet located between the second inner wall and second outer wall.

15. The apparatus set forth in claim 12 , further comprising a first L-shaped bracket coupled with the first inner wall for mounting onto a lip of a tank.

16. The apparatus set forth in claim 15 , further comprising a second L-shaped bracket coupled with the second inner wall for mounting onto the lip of the tank.

17. The apparatus set forth in claim 16 , further comprising a first support bracket coupling the first inner wall to an inner wall of the tank.

18. The apparatus set forth in claim 17 , further comprising a second support bracket coupling the first inner wall to an inner wall of the tank.
