Abstract

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>

Description

Изобретение относитс  к сортировочным барабанам с перфорированной боковой поверхностью обечайки и предназначено преимущественно дл  сортировани  грубо распушенной, загр зненной волокнистой суспензии из макулатуры .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.

Цель изобретени  - повышение качества очищенной суспензии и уменьшение потерь волокна.The purpose of the invention is to improve the quality of the purified suspension and reduce fiber loss.

На чертеже схематично изображен сортировочный барабан, продольный разрез.The drawing schematically shows a sorting drum, a longitudinal section.

Сортировочный барабан содержит установленную горизонтально с возможностью вращени  обечайку 1, выполненную по своей боковой поверхности с перфорированными отверсти ми дл  слива очищенной суспензии, расположенными в двух зонах 2 и 3, установленных последовательно. Перфорационные отверсти  первой зоны 2, прилегающей к отверстию 4 дл  впуска суспензии, расположенному на одном торце барабана , имеют диаметр 7 - 12,5 мм, а перфорационные отверсти  второй зоны 35 прилегающей к отверстию 5 дл  выпуска отходов сортировани , расположенному на другом торце барабана, имеют диаметр 10 - 30,мм. Диаметр перфорационных отверстий первой зо- меньше диаметра отверстий второй зоны, по меньшей мере, на 2,5 мм.Сортировочный барабан содержит . ребра 6, которые подают суспензию вверх и таким образом разрыхл ют отстой , наход щийс  на дне барабана. Между зонами перфорационных отверстий установлена перегородка 7,вьшолненна  в виде наклонно установленного кольца , jcoTopoe осуществл ет удержание суспензии в первой зоне и передачу ее во вторую зону. Очищенна  масса смываетс  в секции 8 и 9, Жидкость, необходима  дл  разбавлени  суспензии в барабане, подаетс  по распределительной трубе 10, расположенной вне обечайки, к отверсти м 11. Распределительные трубы могут быть расположены и внутри обечайки барабана. Сортировочный барабан установлен с возможностью вращени  по рельсам 12, Приводит в движение -барабан электродвигатель 13 через шестерню 14 иThe 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

гфомежуточную шестерню 15, контактирующую с венцом 16, снабженным торцовыми зубь ми. Сопр женное колесо 17, установленное сверху барабана на переднем рельсе 12, воспринимает образуемый барабаном изгибающий момент. Поэтому необходимо поддерживать барабан только с одного его конца.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.

II

Сортировочньш барабан работает следующим образом.Sorting drum works as follows.

Посредством электродвигател  13 и шестерен барабан вращаетс  вокруг горизонтальной оси.By means of the electric motor 13 and gears, the drum rotates around a horizontal axis.

Через впускное отверстие 4 суспенThrough the inlet 4 suspended

зи  поступает внутрь обечайки в первую зону 2 перфорационных отверстий с мелкой перфорацией. Суспензи  сор- тируетс  и поступает через отверстие в секцию 8. Далее неочищенна  суспензи  поступает во вторую зону 3 сортировани , где обечайка выполнена с более крупными отверсти ми. Во второй секции так же происходит сортирование массы, в которой еще оченьzi 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

много комков и котора  сильно загр знена . Очищенна  суспензи  поступает в секцию 9. Отходы, через отверстие 5 поступают на транспортирующую ленту. Ребра 6 позвол ют исключать застойные зоны на дне барабана.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.

Таким образом, качество очистки суспензин возрастает, так как сортировка происходит в нескольких зонах с различной перфорацией, а потери волокна уменьшаютс .Thus, the quality of purification of suspensin increases, since sorting occurs in several zones with different perforations, and fiber loss is reduced.
