Abstract

Устройство (10) содержит цилиндрический барабан (20), который поддерживается ободной конструкцией (21, 22) на валу (25). Наружная поверхность барабана (20) содержит несколько фильтровальных пластин (23), образующих цилиндрическую фильтрующую поверхность. Каждая фильтровальная пластина (23) прикреплена к ободной конструкции (21, 22) с помощью по меньшей мере трех мест (Р1, Р2, Р3) крепления. Первое углубление (46) проходит в фильтровальную пластину (23), а крепежный фланец (110) расположен, по меньшей мере частично, в первом углублении (46). Продольный крепежный элемент (120) с первой концевой части (121) прикреплен к крепежному фланцу (110), а со второй концевой части (122) прикреплен к ободной конструкции (21, 22). По меньшей мере одно защелкивающееся средство (140) расположено в крепежном фланце (110) или в ободной конструкции (21, 22), или в них обоих. Фильтровальная пластина (23) установлена на барабане (20) путем прижатия фильтровальной пластины (23) в радиальном направлении к барабану (20) так, что защелкивающееся средство (140) закрепляет фильтровальную пластину (23) на ободной конструкции (21, 22) барабана (20). Наружная поверхность фильтровальной пластины (23) не имеет разрывов, что приводит к большей эффективной фильтрующей площади в фильтровальной пластине (23).The device (10) contains a cylindrical drum (20), which is supported by a rim structure (21, 22) on the shaft (25). The outer surface of the drum (20) contains several filter plates (23), forming a cylindrical filter surface. Each filter plate (23) is attached to the rim structure (21, 22) with at least three attachment points (P1, P2, P3). The first recess (46) extends into the filter plate (23), and the mounting flange (110) is located at least partially in the first recess (46). A longitudinal fastener (120) is attached to the mounting flange (110) at the first end part (121), and attached to the rim structure (21, 22) at the second end part (122). At least one snap-fit means (140) is located in the mounting flange (110) or in the rim (21, 22), or both. The filter plate (23) is mounted on the drum (20) by pressing the filter plate (23) in the radial direction to the drum (20) so that the locking tool (140) secures the filter plate (23) on the rim (21, 22) of the drum ( 20). The outer surface of the filter plate (23) has no gaps, which leads to a larger effective filtering area in the filter plate (23).
