ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a delivery device for distributing a fluid on an inner surface of a bore of a pipeline, typically, for distributing a cleaning fluid, such as a cleaning liquid, a disinfecting, sanitising or sterilising liquid or gas on the inner surface of a bore of a pipeline.
BACKGROUND OF THE INVENTION
Pipelines which are used for conveying materials, in particular, food grade materials where the materials are conveyed by a conveying medium, for example, conveying air, require cleaning, and may also require sanitizing at predetermined intervals. Typically, it is necessary to coat the inner surface of the bore of a pipeline with a cleaning or sanitizing liquid. Filling the pipeline with the appropriate liquid has been used. However, such an operation requires a substantial volume of liquid, with attendant costs and disposal concerns.
There is therefore a need for a delivery device for distributing a fluid on an inner surface of a bore of a pipeline run.
SUMMARY OF THE INVENTION
According to the invention there is provided a shuttle-type delivery device, hereinafter referred to as a slug for distributing a fluid on an inner surface of a bore of a pipeline. The slug is adapted to slidably engage the bore of the pipeline, and includes a reservoir for the fluid that is to be distributed on the inner surface of the bore of the pipeline. The slug also includes an outlet or outlets which communicates with the reservoir for distributing the fluid onto the inner surface of the bore of the pipeline. In use, the reservoir is charged with the fluid, placed in the bore of the pipeline, and urged through the bore of the pipeline by the conveying medium so that fluid in the reservoir is dispensed by the discharge means along the inner surface of the pipeline bore.
The invention will be more clearly understood from the following description of embodiments thereof which are given by way of example only, with reference to the accompanying drawings.
