    摘要： The screening apparatus according to the invention is used for processing contaminated fibrous suspension, such as is produced during the preparation of waste paper. It has a housing (1) with a screen (3) which divides off an accepts chamber (2) from housing (1). A rotor (4) can be moved along close to the screen (3), by which the latter is kept free and, in addition, a rotational flow is produced. The housing (1) has a main part (7), which is cylindrical and of which the center is at an oblique angle (α) to the axis (12) of the rotor (4) which is between 1 and 60°, preferably between 5 and 25°. The typical position of use of this apparatus is the upright arrangement.

    摘要： A screening device for the wet screening of a paper fiber suspension comprising at least one screen plate having a plurality of screen openings, a support structure being detachably attachable to the screen plate, a rotor movable adjacent the screen plate and an outlet opening for a portion of the paper fiber suspension passing the screen openings The support structure of the device is characterized by an outer support ring and an inner support ring and at least one middle support element arranged radially between the inner and outer support rings to support the at least one screen plate. Elastic pre-stressing against the screen plate is generated, and as a result of the elastic pre-stressing, the screen plate exerts compressive forces on at least one radially intermediate support element and respectively exerts tensile forces both on the inner support ring and on the outer support ring.
