Abstract
The present invention concerns a feed and accept duct system (4) for hydrocyclones (1), comprising common feed and accept ducts (7,8) which have by connecting tubes been connected to the parallel hydrocyclones. This type of construction is used, for instance, in purifying fiber suspensions, in which process the suspension is fed into the hydrocyclones (1) and the purified suspension is removed therefrom as a so-called accept fraction into the accept duct (8). It is essential in the invention that the connecting tubes of the feed and accept ducts (7,8) have been so placed on the different hydrocyclones (1) that the tubes are located substantially in parallel, that the feed and accept ducts have been formed inside a common shell (5) by dividing the space confined by it into two parallel ducts by means of a zigzag partition (6), and that the ends of the connecting tubes (11,12) are located at the folds formed by the bights of the partition, the partition confining the feed duct connecting tubes to be on the feed duct side and the accept duct connecting tubes to be on the accept duct side.
