Embodiment Construction
[0042] exist figure 1 A discontinuously operating single filter plant 100 according to the invention is shown in .
[0043] The single filter device has a filter housing 20 with an inlet channel 23 , an outlet channel 26 and an internal filter chamber. In addition, a temperature adjustment hole for accommodating the electric heating cartridge is provided in the housing 20 , so as to realize uniform temperature adjustment of the entire housing 20 .
[0044] In the illustrated embodiment, the installed drive unit 45 comprises a hydraulically operated cylinder, by means of which the filter carrier element 40 is axially displaceable.
[0045] The filter carrier element 40 carries the filter insert 10 on its lower end side, which in the illustrated embodiment consists of a central, flow-through support profile 12 and a plurality of disk filter elements 11 stacked on top (so-called leaf filter elements ) is formed like a tower cake. The individual disk filter elements 11 each hav...

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.
Description
technical field [0001] The present invention relates to a filter device for filtering fluids over a large area, comprising at least: [0002] - a housing with at least one inlet channel and at least one outlet channel and [0003] - a filter carrier element movable along the housing bore with at least one filter element, which in the production state is to be arranged in the filter chamber between the inlet channel and the outlet channel of the housing, [0004] - wherein the filter insert has a flow-through base element from which a fluid flow branches off into a plurality of individual filter elements, or a plurality of fluid flows from the individual filter elements are combined in the filter device. Background technique [0005] In filter systems of the mentioned type, at a temperature of up to 350° C. and a pressure of up to 300 bar, the plastic melt flows through into a filter element arranged in a cylindrical filter housing, which implements Large area filters in th...
