Abstract (en)
[origin: ES8306968A1] Cleaning device for the internal peripheral surfaces of pipelines or hollow cylindrical vessels, including instrument carriers having at least one working head being fixable in a working position and being movable along defined feed paths through the interior of the pipelines or vessels which are invisible from the outside, and instruments mounted on the at least one working head, the instruments including rotatable brushes being mounted on said working head and being pressable against inner wall surfaces to be cleaned, at least one suction nozzle being mounted on the working head and being movable into alignment with a given brush engagement region of a pipeline or vessel, an injector having a suction side connected to the suction nozzle, a discharge side and a propulsion nozzle, a propellant line feeding the propulsion nozzle of the injector from outside the pipeline or vessel, and a dust collecting bag connected downstream of the discharge side of the injector.
