Problems solved by technology

This may cause serious injury to the user when the follower plate suddenly sinks or may also be splashed
[0005] From a production technology point of view, the air in the system is the most unfavorable factor, because after a certain number and size of air bubbles, the transfer pump may no longer be able to seal the material in the system, and / or because of the Air causing mixing ratio problems or even disrupting the production process

Embodiment Construction

[0022] The device 2 shown in the figures is used to seal and empty a container 6 of a particularly viscous liquid 4, or to apply air pressure to the liquid.

[0023] The device 2 has a cylindrical rubber seal 8 arranged on the circumference of the device 2 . The sealing part comprises 4 axially arranged one after the other, radially outward protruding, staggered outer diameter sheet seal rings 10 (however, all possible other sealing methods and forms can also be considered, for example with solid or hollow (hose type) cross-section of one or more sealing rings). Thus, the sealing portion 8 is adapted to be placed in the cylindrical inner contour 12 of the thin steel drum 6 and is also circumferentially sealed. The inner profile of the bucket 6 matched with the device 2 of the present invention extends to the outside of the thin steel lid bucket without narrowing the size to the bung mouth 16. In order to store and transport the high-viscosity liquid contained, the bung mouth ...

Abstract

The invention relates to a device (2) for sealing and evacuating or applying gas pressure to a paste-like liquid in a container, the interior chamber thereof having a cylindrical inner contour (12). Said device comprises: a seal (8) which is arranged on a circumference of the device (2) and is adapted to be inserted into the cylindrical inner contour (12) of a container in order to seal the circumference of said container, and which delimits the exterior (18) of the device (2) from the interior (20) of the device; a connection device (22) which is arranged on the exterior (18) of the device (2) and which is configured for connecting an evacuation pump; and an open-pored, porous wall (24) in the interior of the device (2), said wall having a conduit connection (25) to the connection device (22).

Description

technical field [0001] The present invention relates to a device for sealing and emptying (or applying gas pressure) especially high viscosity liquids in containers, the inner cavity of which has a cylindrical inner contour. Background technique [0002] For example, in the production and processing of plastics, it is a common technological task to pack viscous (high viscosity) materials (in most cases without (necessary) agitation and phase stability in usually cylindrical barrels for storage and transport) is pumped out of the barrel during further processing with a pump (usually a special pump for high viscosity liquids). Since such materials are not self-leveling, ie are too viscous to form a flat, level surface by their own weight alone, so-called "follower plates" are used (on which the transfer pump is usually mounted). These follower plates are cap-like devices which (after removal of the original bung lid) are fitted into the cask and are equipped with sealing ring...
