Abstract

A tank cleaning machine comprising a housing having an inlet and a stationary guide diverter disposed within the housing. A gearing mechanism is attached to the stationery flow diverter. A nozzle extends from the housing wherein the nozzle is in fluid communication with the inlet and the nozzle includes an inclined portion extending from a horizontal portion of the nozzle. A drag limiter extends into a hydraulic fluid reservoir to limit the rotation speed of the gear.

Claims

1. A turbo jet mixer comprising:

an inner housing having an inlet, the inner housing including a coupling section, a generally tubular section, and an end plate, the interior of the generally tubular section defining an inner chamber;

an outer housing positioned substantially about the inner housing, the outer housing being rotatably coupled to the inner housing, the outer housing having an inner wall;

a nozzle coupled to the outer housing, the nozzle coupled to an aperture in the outer housing to fluidly connect the inner chamber to the nozzle;

a continuously rotatable dashpot coupled to the inner housing;

a gearing mechanism coupled to the inner housing positioned to operatively couple a ring gear coupled to the outer housing to the dashpot.

2. The turbo jet mixer of claim 1, wherein the inner housing further comprises a flange positioned to fluidly couple the turbo jet mixer to a supply pipe.

3. The turbo jet mixer of claim 1, wherein the generally tubular section of the inner housing comprises a series of vanes connecting the coupling section and the end plate, so that the inner chamber is exposed to at least a portion of the nozzle throughout a full rotation of the outer housing.

4. The turbo jet mixer of claim 1, wherein the generally tubular section of the inner housing comprises a solid portion and a window, so that the solid portion prevents fluid communication between the inner chamber and the nozzle when the nozzle is substantially overlapping the solid portion, and the window allows fluid communication between the inner chamber and the nozzle when the nozzle is substantially overlapping the window through the rotation of the outer housing.

5. The turbo jet mixer of claim 1, wherein the nozzle is positioned to impart a rotational force on the outer housing through a resultant force from jetting fluid through the nozzle.

6. The turbo jet mixer of claim 5, wherein the nozzle is mounted at an angle to the outer wall of the outer housing.

7. The turbo jet mixer of claim 5, wherein the nozzle extends normally from the outer wall of the outer housing, and includes an angular deflection to impart the rotational force.

8. A turbo jet mixer comprising:

a housing having an inlet;

a stationery flow diverter disposed within the housing;

a gearing mechanism that is attached to the stationery flow diverter, at least a portion of the housing is attached to the gearing mechanism;

a nozzle extending from the housing, the nozzle positioned in fluid communication with the inlet, the nozzle including an inclined portion extending from a horizontal portion of the nozzle; and

a drag limiter that extends into a hydraulic fluid reservoir within the housing to limit the rotation speed of the gear.

9. The turbo jet mixer of claim 8, wherein the content of the hydraulic reservoir also lubricates the gearing mechanism;

10. The turbo jet mixer of claim 8, wherein the inclination between the horizontal portion of the nozzle and the inclined portion of the nozzle may be field adjusted.

11. The turbo jet mixer of claim 8, wherein the hydraulic fluid reservoir is sealed to facilitate installation on a side of a storage tank.

12. The turbo jet mixer of claim 8, wherein the flywheel is attached to an inner portion of the gearing.

13. The turbo jet mixer of claim 8, wherein the stationery flow diverter is attached to the inlet.

14. The turbo jet mixer of claim 8, wherein the stationery flow diverter diverts the flow of fluid toward the nozzle.

15. The turbo jet mixer of claim 8, wherein the housing rotates about the stationary flow diverter.
