    • A filtering device (100′) for the large-area filtration of polymer melts comprises at least: a housing (20; 20′) with at least one inlet channel (23; 71′) and at least one outlet channel (26; 61′) and a filter carrier element (40, 40′), which can be moved longitudinally in relation to a housing bore and has at least one filter insert (10; 10′), which in a production position can be arranged in a filter chamber (24; 24′) between the inlet channel (23; 71′) and the outlet channel (26; 61′) of the housing (20; 20′), wherein the filter insert (10, 10′) has a main element (12, 12′) through which the flow can pass, and from which a fluid stream branches off to multiple individual filter elements (11, 11′) or in which multiple fluid streams from the individual filter elements are combined. The filter insert (10, 10′) is arranged on an end face of the filter carrier element (40, 40′). The filter chamber (24, 24) is formed by a housing bore, which extends up to a mouth (25) on an outer side of the housing and into which the filter insert (10, 10′) can be pushed by moving the filter carrier element (40, 40′), and a closure element (41, 41′), which can be placed onto the mouth (25) of the housing bore and/or can be inserted therein when the filter carrier element (40, 40′) is lowered into the housing bore or thereafter.
    • 用于聚合物熔体的大面积过滤的过滤装置(100')至少包括:具有至少一个入口通道(23; 71')和至少一个出口通道(26; 61')的壳体(20; 20') ')和过滤器载体元件(40,40'),其可以相对于壳体孔纵向移动并且具有至少一个过滤器插入件(10; 10'),其在生产位置可以布置在过滤器 在所述入口通道(23; 71')和所述壳体(20; 20')的出口通道(26; 61')之间的腔室(24; 24'),其中所述过滤器插入件(10,10')具有主体 流体可以通过该元件(12,12'),并且流体流从该元件(12,12')分支到多个单独的过滤器元件(11,11'),或者来自各个过滤器元件的多个流体流被组合。 过滤器插入件(10,10')布置在过滤器承载件(40,40')的端面上。 过滤室(24,24)由壳体孔形成,该壳体孔延伸到外壳的外侧上的口(25),并且过滤器插入件(10,10')可以通过移动过滤器 载体元件(40,40')和封闭元件(41,41'),当所述过滤器承载元件(40,40)能够被放置在所述壳体孔的所述口部(25)上时,和/ ')下降到壳体孔或其后。
