摘要

The support structure for a sieve unit (5) for the filtration of highly viscous medium such as rubber mixtures for separating the rubber mixture from foreign substances and impurities, comprises a frontal cross-sectional surface with hole for the placement of the sieve unit, and transverse channels, which flow into the cross-sectional surface. The channels facilitate the passage of the filtered medium through the support structure, which is laid out to be a two-component module and which is composed of a perforated plate (2) with holes and carrier (3). The support structure for a sieve unit (5) for the filtration of highly viscous medium such as rubber mixtures for separating the rubber mixture from foreign substances and impurities, comprises a frontal cross-sectional surface with hole for the placement of the sieve unit, and transverse channels, which flow into the cross-sectional surface. The channels facilitate the passage of the filtered medium through the support structure, which is laid out to be a two-component module and which is composed of a perforated plate (2) with holes and carrier (3). The holes of the perforated plate and the cross-sectional surface are joined with one another to form the channels for the passage of the filtered medium. The holes of the cross-sectional surface are smaller than the holes of the perforated plate. Dividing elements (8) are formed at the frontal surface of the carrier that faces the perforated plate. The edges of the dividing elements adjoin the perforated plate. The channels are formed by the holes of the cross-sectional surface. The dividing elements have a concentric profile. The holes of the plate are arranged between the dividing elements. A closable compressed air bore is present at the center of the carrier and is closed by a stopper (10) during the filtration of the medium. The perforated plate has a constant thickness. The surface of the carrier that is turned away from the perforated plate has a convex shape. Independent claims are included for: (1) filtration device for the filtration of rubber mixtures; (2) device for removing a block of a highly-viscous medium adhering to the carrier of the supporting structure; and (3) method for removing a block of a highly-viscous medium adhering to the carrier of the supporting structure.
