ABSTRACT:
The invention relates to a device for the removal of particles and/or screenings from a liquid running in a laundry. A screen with openings in the shape of a cylinder jacket reaches into the laundry and is tilted upwards. The screen is partly immersed in the liquid, and parallel haulage track for the material is provided. The track is located spaced from the screen, and has the form of a screw conveyor with a housing, a shaft and a conveyor helix. The conveyor helix moves alongside the screen and picks up the material and transports it upwards. The openings with their lengthwise direction are inclined relative to the axis of the cylindrical jacket-shaped screen so that they are situated approximately parallel to the effective direction of the total force exerted on the material by the conveyor helix.
