Abstract

The invention relates to a follower plate device for sealing and evacuating a container that has a cylindrical inner contour and contains a particularly paste-like liquid (6), said device comprising aseal (8) arranged on a periphery of the device (2) and designed so as to be able to to be inserted into the cylindrical inner contour of the container (4) such that it seals around the periphery, andmarking the boundary between an outer side (10) of the device (2) and an inner side (12) of the device (2), and a line (20) extending through from the inner side to the outer side of the follower plate device, arranged on the outer side (10) for connecting to a line connection (18) leading further to an evacuation pump (16). The invention is characterized by a replaceable open-pored porous component (22) through which the line (20) is guided.

Description

technical field

[0001] The invention relates to a bucket driven disk device for sealing and evacuating containers having a cylindrical inner contour and containing, in particular, viscous liquids. Background technique

[0002] This is a known process-technical task, for example in the manufacture and processing of multicomponent plastics, of viscous (highly viscous) During processing, pumps (usually special pumps for highly viscous liquids) are used to transport them from barrels. Because these materials are not always self-leveling, that is, they are so viscous that they form a flat, level liquid surface not just due to their own weight, so-called "bucket followers" are used: from The disc is a housing device or sealing device in the form of a cylindrical piston, which (after removal of the original drum housing) is inserted vertically into the drum from above and is provided with a sealing ring which completely seals the drum driven disc to the barrel wall. Thus, the ke...
