    A sorter drum is constructed with a perforated casing and is rotatable around a horizontal axis, for sorting waste paper fibrous suspension containing coarsely pulped waste paper loaded with all the coarse impurities from the waste paper bales, and has perforation sizes of more than 5 mm diameter. The suspension is introduced via one end wall of the sorter drum and the liquid waste is extracted via the other end wall, while the good pulp stock is drawn off through the perforations. The casing of the sorter drum has at least two different sets of perforations, the hole width of which differs by more than 2.5 mm, following one after the other in the axial direction, the drum section (2) with the finer perforations being disposed at the inlet and (4) of the sorter drum (1). <IMAGE>

    专利说明:

    The invention relates to sorting drums with a perforated side surface of the shell and is intended primarily for sorting coarsely fluffed, contaminated fiber suspension from waste paper.
    The purpose of the invention is to improve the quality of the purified suspension and reduce fiber loss.
    The drawing schematically shows a sorting drum, a longitudinal section.
    The sorting drum contains a horizontally-mounted rotatably shell 1, made on its side surface with perforated holes for draining the cleaned slurry arranged in two zones 2 and 3 arranged in series. The perforations of the first zone 2 adjacent to the suspension inlet 4, located on one end of the drum, have a diameter of 7-12.5 mm, and the holes of the second zone 35 adjacent to the outlet 5 to release sorting waste located on the other end of the drum, have a diameter of 10 - 30 mm. The diameter of the perforation holes of the first one is smaller than the diameter of the holes of the second zone by at least 2.5 mm. The sorting drum contains. fins 6 which feed the slurry upwards and thus loosen the sludge located at the bottom of the drum. A partition 7 is installed between the zones of the perforations, implemented as an obliquely mounted ring, jcoTopoe retains the suspension in the first zone and transfers it to the second zone. The cleaned mass is rinsed off in section 8 and 9, the liquid needed to dilute the suspension in the drum, is fed through the distribution pipe 10 located outside the shell to the holes 11. The distribution pipes can be located inside the shell of the drum. The sorting drum is rotatably mounted on rails 12; It drives a drum-13 electric motor through gear 14 and
    The intermediate gear 15 is in contact with the rim 16, which is provided with end teeth. The mating wheel 17 mounted on top of the drum on the front rail 12 senses the bending moment formed by the drum. Therefore, it is necessary to support the drum from only one end.
    I
    Sorting drum works as follows.
    By means of the electric motor 13 and gears, the drum rotates around a horizontal axis.
    Through the inlet 4 suspended
    zi enters the shell in the first zone of 2 perforations with small perforations. The suspension is sorted and fed through an opening to section 8. Next, the unpurified suspension enters the second sorting zone 3, where the shell is formed with larger openings. In the second section, the mass is also sorted, in which there is still very
    many lumps and which are heavily polluted. The cleaned suspension enters section 9. The waste, through the opening 5, enters the transporting belt. The ribs 6 make it possible to eliminate stagnant zones at the bottom of the drum.
    Thus, the quality of purification of suspensin increases, since sorting occurs in several zones with different perforations, and fiber loss is reduced.

    SORTING DRUM mainly for sorting coarsely dissolved, contaminated fibrous slurry from waste paper containing horizontally rotatable casing made on the side surface with perforated holes with a diameter of more than 5 mm for draining the cleaned suspension, suspension inlet hole located at one end of the drum, hole for the release of sorting waste located on the other end of the drum, characterized in that, in order to improve the quality of the purified suspension In order to reduce and reduce fiber losses, it has at least two zones of perforation openings installed in series, the perforations of the first zone adjacent to the suspension inlet opening have a diameter of 7-12.5 mm, and the perforations of the second zone arriving to the hole for the discharge of sorting waste, have a diameter of 10 to 30 mm, while the diameter of the perforations of the first zone. Less than the diameter of the perforations of the second zone is at least 2.5 mm.
