  • Cleaning system for cleaning fluid-conducting tubing
    Patent number: 5592990
    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.

  • Cleaning system for cleaning fluid-conducting tubing
    Patent number: 5176204
    Abstract: A cleaning system for cleaning tubing by circulating balls through the tubing includes a system for separating and recirculating the balls back to the upstream side of the tubing. The separator includes a hollow separator tube having perforations through its wall such that the balls accumulate in a chamber on the outer side of the hollow separator tube while the fluid flows through the interior of the hollow separator tube through a passageway to the atmosphere.

  • Cleaning system for cleaning fluid-conducting tubing
    Patent number: 5086833
    Abstract: A cleaning system for cleaning tubing by means of balls circulated with the fluid through the tubing includes a separator having a grid structure in a separator conduit, and an arrangement to move balls tending to accumulate on the upstream face of the grid structure towards a ball outlet at the separator conduit where they may be more effectively drawn into a recirculating conduit by a negative pressure at the inlet thereof.
