Abstract
A cleaning head for cleaning elongated tubes having multiple separate paths for different cleaning fluids to be supplied in sequence, and an impeller adapted to throw a first portion of the cleaning fluid centrifugally onto the tube inner wall, and to pass a second portion axially of the tube for subsequent mergence with the first portion, and an outer plenum directing cleaning fluid onto the tube exterior, for cleaning the entire tube top to bottom and inside and out.
Claims21
Cleaning fluid distribution head for cleaning elongated tubes, comprising structure adapted for endwise reception in a tube to be cleaned, said structure defining a series of flow passages communicating respective sets of inlet and outlet ports for separate delivery of different fluids to the tube for tube cleaning, said outlet ports being of a number and position to direct said fluids generally axially of the tube without contact of the fluid with adjacent tube inner wall, and means carried by said structure within said tube adapted and arranged to rotate responsive to impingement of cleaning fluids thereon from any of said outlets and thereby to redirect a first portion of outlet port delivered fluids centrifugally laterally outward onto the adjacent tube inner wall for sheet flow thereon, and to pass a second portion of said delivered fluids axially of said tube for mergence beyond said means with said redirected fluid portion on the tube inner wall, whereby the entire tube inner wall is subjected to cleaning fluids.
