Abstract

A cleaning apparatus is provided for cleaning an inner surface of a container. A spray head is arranged for operable fluid communication with a fluid pump and has a nozzle configured to disperse liquid in a mist. A mount carries the spray head and is removably supportable on a container having an inner surface to be cleaned. When removably supported on a container, the mount supports the spray head in a position within the container where the spray head can coat the inner surface of the container with mist.

Claims (25)

1. A cleaning apparatus for cleaning an inner surface of a container, the apparatus comprising:

a fluid pump;

a first spray head arranged for operable fluid communication with the fluid pump and having a nozzle configured to disperse liquid in a mist; and

a mount carrying the first spray head and configured to be removably supported on a container having an inner surface to be cleaned, and further configured to support the first spray head in a position within the container to be cleaned,

the pump being arranged to draw liquid from the container to be cleaned and to pump the liquid back into the container through the first spray head.

2. The cleaning apparatus of claim 1 in which the first spray head is configured to issue a mist comprising fine droplets of liquid on the order of a micron or less in diameter.

3. The cleaning apparatus of claim 1 in which the first spray head is arranged to operate in a closed recirculatory loop with the pump.

4. The cleaning apparatus of claim 3 in which the pump is configured to draw liquid from a pool of liquid formed in the container from liquid dispersed into the container by the first spray head, and to pump that liquid back to the first spray head in a recirculatory fashion.

5. The cleaning apparatus of claim 1 further comprising a heat source configured to heat liquid to be dispersed by the first spray head.

6. The cleaning apparatus of claim 5 in which the heat source comprises a steam line in operable communication with a pressurized air line.

7. The cleaning apparatus of claim 1 including an enzymatic solution arranged for fluid communication with the first spray head, the first spray head being configured to disperse the enzymatic solution in a mist.

8. The cleaning apparatus of claim 1 in which the first spray head is configured to disperse liquid in a mist in a pattern producing a fog-like atmosphere within a container to be cleaned.

9. The cleaning apparatus of claim 1 in which the first spray head comprises a plurality of spray nozzles, each configured to dispense liquid in a mist.

10. The cleaning apparatus of claim 1 in which the first spray head is configured to disperse liquid in a mist over a 360 degree circular spray pattern.

11. The cleaning apparatus of claim 1 in which the mount includes a lid configured to be removably supported over an opening in a container to be cleaned.

12. The cleaning apparatus of claim 1 in which the lid is configured to provide a liquid-tight seal with an opening in a container to be cleaned.

13. The cleaning apparatus of claim 1 further including a second spray head carried by the mount in a position to be disposed within a container to be cleaned when the mount is supported on such a container, the second spray head having a nozzle configured to dispense liquid in a high pressure liquid stream.

14. The cleaning apparatus of claim 13 in which the nozzle of the second spray head is in operable fluid communication with the pump.

15. The cleaning apparatus of claim 13 in which the nozzle of the second spray head is movably supported.

16. The cleaning apparatus of claim 13 in which the nozzle of the second spray head has a rifled bore configured to direct fluid passing through the nozzle into a vortical stream.

17. The cleaning apparatus of claim 13 in which the second spray head is arranged to operate in a closed recirculatory loop with the pump.

18. The cleaning apparatus of claim 13 including at least one chemical solution container arranged for fluid communication with at least one of the first and second spray heads.

19. The cleaning apparatus of claim 13 in which separate chemical solution containers are arranged for fluid communication with the respective first and second spray heads.

20. The cleaning apparatus of claim 1 in which the fluid pump is carried by the mount.

21. The cleaning apparatus of claim 1 in which the fluid pump is configured to provide liquid under pressure to be mixed with pressurized gas and dispersed through the first spray head into a container to be cleaned.
