摘要: A filtering device for removing dirt particles and contaminants from a plastic melt is disclosed. The filtering device includes a housing having a filter chamber, an inlet for feeding plastic melt, an outlet for channeling plastic melt out, and a dirt outlet for discharging dirt particles from the housing. The filtering device also includes a filter element arranged in the filter chamber to retain any dirt particles contained in the stream of melt, and a cleaning unit for cleaning the filter element of dirt particles retained by means of the filter element. The cleaning unit having a cleaning head with a scraper member for detaching dirt particles from the filter element. The scraper member is coupled to a servomechanism to press the scraper member onto the surface of the filter element. The servomechanism has at least one bellows cylinder including a foot section, a head section, a deformable bellows element, and a pressure chamber of variable volume.

摘要: 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.

摘要: A filter mesh assembly configured to control particulate material in a filter assembly of a plastic extruder. The filter mesh assembly includes a wire mesh filter having a square weave construction defining a predetermined pore size with the wire mesh filter having flattened surfaces of adjacent wires on the same plane and configured to allow a portion of the scraper to move across the wire mesh filter assembly. The assembly also includes a wire mesh supporter having a square weave construction and a characteristic of sufficient strength to support the wire mesh filter against a breaker plate. The wire mesh filter and the wire mesh supporter are diffusion bonded to each other as a unified structure and disposed in a housing between an inlet and breaker plate. The configuration allows passage of molten plastic through the breaker plate and lateral movement of material, parallel to the breaker plate.
