Published by No. 896. According to this, fine fragments of the waste paper suspension are discharged through holes in the peripheral wall of the drum, and coarse fragments are discharged through a connection located axially opposite the intake opening on the end face of the drum. Ru. However, this actually results in the discharge of waste liquid, which mainly has a relatively low fiber concentration, at the end face of the drum, and at the same time, on the other hand, because the diameter of the holes is chosen too large, it is discharged through the peripheral wall of the drum. There is a risk that high-quality paper stock may be relatively heavily contaminated.

することにある。Due to the different qualities of the waste paper introduced into the pulp disintegrator, which is generally connected upstream of the sorter drum, it is practically impossible to make suitable adjustments in this regard in all cases. The object of the invention is therefore to provide a drum that is adapted to different waste paper qualities in such a way that, on the one hand, a high-quality paper stock that is purified as well as possible is produced and, on the other hand, fiber losses in the discharge of waste liquid at the end faces of the drum are as low as possible. It's about doing.

The first drum part 2 adjacent to the drum part 2 is provided with fine perforations, i.e. has a small perforation diameter. In this case, the diameter of the holes is between 7 and 12.5 mm for the first drum part 2 of the fine holes.

It lies between 30m and 30m. [Wochenbl, Fuyua, Papier Elf Apricatio 7 (Wochenbl)

n) J 1981, pages 927-930, with a sorter drum similar to the present invention, a generally 18 mm hole relative to the hole in the sorter drum at stock concentrations of 4 to 6%. diameter has been provided. According to the invention, therefore, very small hole diameters are used on the intake opening side. According to the invention, it is also surprising that the intended and desired effect is produced by the arrangement of the drum part with fine holes on the intake opening side of the drum and the arrangement of the other drum part on the discharge opening side of the drum. Ta. Up to now, in all known sorting devices for waste paper recycling bins, it has been arranged to initially process with large hole diameters and step-by-step with smaller hole diameters.

により、懸濁液のドラム部分３への搬出が行なわれる。The waste paper suspension produced from waste paper is: 1. For example, it is supplied from a pulp disintegrator to a sorter drum via a chute 42. The sorter drum rotates about a horizontal axis and for this purpose is pivoted via rails 6 on running rollers 7, which are shown in dotted lines. In this case, the drive takes place by the motor 48 via a spur gear 47 and via a pinion 49 and an idler gear 50 in order to reduce the high motor speed. A counterroller 15, which rests on the front rail 6 above the drum, receives the bending moments caused by the drum and its contents. This means that the drum only needs to be supported at one end. The drum has within it rotating lips 11 parallel to its axis of rotation, each lip transporting the waste paper suspension upwards and thus disintegrating the sediment layer at the bottom of the drum. Damping of the suspension in the first drum part 2 takes place by means of a rotating swash plate 12 configured as an obliquely arranged ring, which acts as a partition between the two drum parts 2 and 3; Further, the suspension carried out by the rotating lip 11 in the vicinity of the rotating swash plate 12 overcomes the barrier constituted by the rotating swash plate 12 in the state shown in the figure, so that the suspension is carried out to the drum portion 3. It is done.

従って特に第一のドラム部分２において第二のドラム部

れた再生装置の最適な使用という結果を生じる。Through the relatively fine holes in the drum section 2, the relatively well purified quality stock is sorted into a corresponding compartment 13 of a water tank 30 arranged below the sorter drum. Aquarium 3
In the compartment 19 associated with the second drum section 3 of 0, due to the larger diameter of the holes, a highly soiled fine stock is obtained, which in a series of steps is suitable It must be further processed in a corresponding sorter device or a combined pulp disintegrator-sorter device with dust removal. It is also possible to send the quality paper stock discharged there through a device known as a dedusting device. On the other hand, the fine stock discharged from section 13 only needs to be reprocessed in a sorter device or a combined disintegrator-noter device, with the dust removal effect being at most a small amount. It's nothing more than that. This naturally results in an optimal use of playback devices developed for different purposes.

る。However, it is also possible to provide similar distribution pipes inside the sorter drum. The waste liquid discharged at the discharge opening side is carried out by a conveyor belt 51 attached to a roller 52. At this time, the guide plate 53 prevents the waste liquid from deviating. If the concentration of the waste liquid is too low, the conveyor belt 51 must of course be replaced by a water tank, from which the suspension can be pumped up.

なる。By arranging the rotating shaft of the drum at a slight downward inclination with respect to the discharge opening, the discharge of waste liquid is facilitated.
