Abstract
A cleaning system for cleaning tubing by balls circulated with the fluid through tubing, includes a ball collector housing having an apertured partition permitting the fluid, but not the balls, to pass therethrough, so that the balls accumulate in the upper compartment and are recirculated into the tubing by controlling various valves. The upper compartment is closed by a removable cover to permit adding balls to the upper compartment or removing balls therefrom.
Claims18
A cleaning system for cleaning tubing used for conducting a fluid therethrough, which system includes balls circulated with the fluid through the tubing from its upstream side to its downstream side, separator means for separating the balls from the fluid at the downstream side of the tubing, and recirculating means for recirculating the balls back to the upstream side of the tubing;
- said recirculating means comprising:
- a ball collector housing having an interior containing an apertured partition permitting the fluid, but not the balls, to pass therethrough, and dividing the interior of the housing into an upper compartment and a lower compartment;
- a first passageway connecting one side of said upper compartment to the downstream side of said tubing;
- a second passageway connecting a first point on an opposite side of said upper compartment to a first point in the upstream side of said tubing;
- a third passageway connecting a second point on said opposite side of the upper compartment to a second point in the upstream side of said tubing to receive a pressure slightly lower than that at said first point in the upstream side of said tubing but higher than that at said downstream side of the tubing;
- a fourth passageway connecting said lower compartment to a source of lower pressure than that at said downstream side of the tubing as well as at said first and second points in the upstream side of the tubing;
- valves in said first, second, third and fourth passageways controlling the fluid flow therethrough;
- and a cover covering said upper compartment and removable therefrom to permit adding balls to said upper compartment or removing balls therefrom.

- a fourth passageway connecting said lower compartment to the atmosphere;
- valves in said first, second, third and fourth passageways controlling the fluid flow therethrough;
- and a transparent cover covering said upper compartment and removable therefrom to permit adding, removing and viewing the contents of said upper compartment.
