    • 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.

    • A device for filtering a thermoplastic melt, comprising a housing having at least one fluid feed channel and at least one fluid discharge channel and having at least two bores. The bores are in fluid communication with the fluid feed channel and the fluid discharge channel, and each houses a displaceable bolt provided with a filter unit having an inflow side and an outflow side. Each displaceable bolt can be moved at least between a filtering position and a back-flushing position. In a filling position, in which fluid flows from the outflow side of the filter unit to a storage cavity formed in the bore by the movement of the displaceable bolt. When the displaceable bolt moves into the back-flushing position, the fluid then again flows through the filter unit to the at least one back-flushing channel and thus escapes from the housing.
    • 一种用于过滤热塑性熔体的装置,包括具有至少一个流体供给通道和至少一个流体排放通道并具有至少两个孔的壳体。 孔与流体供给通道和流体排出通道流体连通,并且每个容纳设置有具有流入侧和流出侧的过滤器单元的可移位螺栓。 至少在过滤位置和后冲洗位置之间移动每个可移位的螺栓。 在填充位置,其中流体通过可移动螺栓的移动从过滤器单元的流出侧流到形成在孔中的储存腔。 当可移动螺栓移动到后冲洗位置时,流体再次流过过滤器单元至至少一个反冲洗通道,从而从壳体逸出。
