Abstract
1384414 Paper pulp screening device YHTYNEET PAPERITEHTAAT OY JYLHAVAARA 17 Aug 1972 [21 June 1972] 38351/72 Heading B1D Incoming paper pulp suspension is screened by inward flow through cylindrical screen 4, whose outer surface is swept by two hollow vanes 5 (Fig. 2, not shown) which pick up the rejected material from the screen and deliver it to space 13 inside a second screen 14, through which an acceptable fraction of the material is returned to the inlet space 2. Vanes 5 move close to screen 4 and remove material by centrifugal suction. Screen 14 is swept by similar vanes 15 which pick up and deliver the final rejects to outlet 20. Accepts is discharged through outlet 10. The two sets of vanes are connected by ring 8, the tops of vanes 5 being connected by diametral arm 6 to drive shaft 7. Flow directions and screen positions may be varied in alternative constructions.
