Abstract
A device or arrangement for cleaning a pipe separator () in which the separator body () includes an extended, tubular body with an inlet () and an outlet () having essentially the same diameter as the separator body. At the outlet, there is a bend or a loop () designed to maintain a fluid level in the separator. Just before the bend, there is an outlet () with an outlet pipe () for conducting fluid, e.g. water, from the separator. Sand or other particulate materials introduced into the outlet () are returned, using a pump () arranged on the outlet pipe (), together with the fluid from the outlet, to the separator after the bend () by means of reversal with a valve () via a return pipe (). In connection with the outlet (), there is a flushing device having a pipe loop () connected to the outlet pipe () for the return of fluid from the outlet to the nozzles () arranged in the outlet. The nozzles are designed to flush, in a direction downstream of the outlet, any particles having accumulated in the outlet chamber.
