Cleaning system for cleaning tubing

摘要

According to one aspect of the invention, there is provided a cleaning system for cleaning tubing used for conducting a fluid therethrough, the tubing being connected between an inlet pipe and an outlet pipe, the cleaning system including: a receptacle; an apertured partition disposed within the receptacle and dividing the receptacle into a first compartment and a second compartment, at least one cleaning element disposed in the receptacle second compartment, wherein apertures of the apertured partition having a size allowing the fluid, but not the cleaning element to pass through the apertured partition; a fluid supply conduit connected to the receptacle first compartment for establishing fluid communication between the inlet pipe and the receptacle first compartment; a cleaning element supply conduit with a directional valve arranged therein, the cleaning element supply conduit being connected to the receptacle second compartment for establishing fluid communication between the receptacle second compartment and the inlet pipe, wherein the fluid supply conduit and the cleaning element supply conduit form a part of a fluid supply loop for supplying the cleaning element from the receptacle second compartment into the tubing via the inlet pipe; a cleaning element return conduit with a directional valve arranged therein, the cleaning element return conduit being connected to the receptacle second compartment for establishing fluid communication between the outlet pipe and the receptacle second compartment, a fluid return conduit connected to the receptacle first compartment for establishing fluid communication between the receptacle first compartment and the outlet pipe, wherein the cleaning element return conduit and the fluid return conduit form a part of a fluid return loop for returning the cleaning element from the tubing via the outlet pipe into the receptacle second compartment; and a valve arrangement operable to open/close the fluid supply loop and operable to open/close the fluid return loop.

1. A non-motorized cleaning system for cleaning tubing used for conducting fluid therethrough, the tubing being connected between an inlet pipe and an outlet pipe, the non-motorized cleaning system comprising:
a receptacle; an apertured partition disposed within the receptacle and dividing the receptacle into a first compartment and a second compartment, the apertured partition comprising a concaved surface; at least one cleaning element disposed in the receptacle second compartment, wherein apertures of the apertured partition having a size allowing the fluid, but not the cleaning element to pass through the apertured partition; a fluid supply conduit connected to the receptacle first compartment for establishing fluid communication between the inlet pipe and the receptacle first compartment, the fluid supply conduit comprising a tapered end with a tapered end surface within the inlet pipe; a cleaning element supply conduit with a directional valve arranged therein, the cleaning element supply conduit being connected to the receptacle second compartment for establishing fluid communication between the receptacle second compartment and the inlet pipe, the cleaning element supply conduit comprising a tapered end with a tapered end surface within the inlet pipe;
wherein the fluid supply conduit and the cleaning element supply conduit form a part of a fluid supply loop for supplying the cleaning element from the receptacle second compartment into the tubing via the inlet pipe; a cleaning element return conduit with a directional valve arranged therein, the cleaning element return conduit comprising an outlet portion being connected to the receptacle second compartment for establishing fluid communication between the outlet pipe and the receptacle second compartment, a fluid return conduit comprising an inlet portion being connected to the receptacle first compartment for establishing fluid communication between the receptacle first compartment and the outlet pipe, the fluid return conduit comprising a tapered end with a tapered end surface within the outlet pipe;
wherein the cleaning element return conduit and the fluid return conduit form a part of a fluid return loop for returning the cleaning element from the tubing via the outlet pipe into the receptacle second compartment; and a valve arrangement operable to open/close the fluid supply loop and operable to open/close the fluid return loop; wherein the inlet portion of the fluid return conduit is radially misaligned relative to the outlet portion of the cleaning element return conduit, wherein a longitudinal axis of the outlet portion of the cleaning element return conduit forms an angle with a longitudinal axis of the inlet portion of the fluid return conduit, wherein the longitudinal axis of the inlet portion of the fluid return conduit is substantially perpendicular to the apertured partition, wherein the concaved surface of the apertured partition faces the outlet portion of the cleaning element return conduit; wherein the tapered end surface of the fluid supply conduit faces downstream fluid flow in the inlet pipe, the tapered end surface of the cleaning element supply conduit faces away from downstream fluid flow in the inlet pipe, and the tapered end surface of the fluid return conduit faces away from downstream fluid flow in the outlet pipe.
