<p>Purging of dust separator filter hoses without any streaming interruption through the appts. is achieved by using only clean compressed air from outside directed in countercurrent on to the hoses from a ring of nozzles in axial direction and inclined to the hose inside sides. Such nozzle ring is located on the lower section of the hose socket, forming its outlet and attachment to the appts. It is pref. formed from the inner otherwise conical wall of a double walled hose socket by pressing out noses pointing in vertical direction, and having outlets in their approx. horizontal areas.</p> |
