Cleaning and spraying device for sieves in paper machines - has double wall tube with water inlet and hand-wheel operated dirt discharge

摘要

A cleaning/spraying device for sieves or felts in paper or cardboard machines is a double wall tube with a water inlet at one end and a bandwheel operated dirt discharge at the other end. The nozzles are arranged at the bottom of both tubes along a flattened segment of the outer tube. An internal brush cleaning mechanism keeps the nozzle inlets clear. ADVANAGE - This eliminates the risk of deflection or of eccentricity of the inner tube and keeps the nozzles free from obstructions.
