Abstract

Фильтр (1), предложенный в соответствии с изобретением, с вертикальными пластинами (2) содержит пластины (2), каждая из которых содержит трубку (200), соединенную с внешним коллектором (5, 50, 51, 52), причем указанный фильтр (1) отличается тем, что содержит по меньшей мере два внешних коллектора (5, 50, 51, 52), для всех пластин (2) две смежные пластины (2) соединены с двумя разными внешними коллекторами (5, 50, 51, 52), и каждая пластина (2) содержит по меньшей мере один фильтрующий элемент (22), причем каждый фильтрующий элемент (22) состоит по меньшей мере из двух сливных каналов (220) и ткани (221), содержащей отделения (222), в каждое из которых вставлен сливной канал (220). За счет отсутствия одновременной разгрузки двух смежных пластин (2) отделяют только один из двух обращенных друг к другу фильтрационных кеков (6), а не оба. Конструкция этих пластин (2) обеспечивает небольшое надувание фильтрующей ткани (221) во время разгрузки и, следовательно, ограниченное перемещение фильтрационного кека (6). Таким образом, можно уменьшить пространство, обеспечиваемое между пластинами (2), без риска создания застреваний, губительных для работы фильтра (1), при выпадении фильтрационных кеков, и без риска прижимания выгружаемых фильтрационных кеков (6) к пластинам (2) во время фильтрации. Это позволяет увеличить количество пластин (2) в фильтре (1).
