US Patent:

7950530, May 31, 2011

Filed:

Feb 16, 2006

Appl. No.:

11/357660

Inventors:

Jerry McNaughton - Houston TX, US
Stanley W. Ellis - Bakersfield CA, US

International Classification:

B01D 21/26

US Classification:

2105121, 210498, 138114

Abstract:

A compound conduit containing inner and outer conduits with apertures in the former that are angled to direct jets of fluid in a rearward direction from the inner conduit into the annular space is used to draw sludge or undesirable material from a vessel without imposing a vacuum on the system. In conjunction with the compound conduit is a rotary tube seal that allows the conduit to be mounted to an orifice in a tank wall and pivoted or rotated over a range of angles. A tubing drive mechanism grasps the tubing at locations well removed from the distal end and causes the tubing to travel in the direction of the tubing axis. The gripping members in the mechanism engage the sides of the tubing and are capable of shifting position relative to each other to accommodate changes in the curvature of the tubing.
