Device for mixing and degassing a free-flowing compound

Abstract

The device serves for mixing and degassing a free-flowing compound (5), in particular a casting resin containing filler. The device has an evacuable container (1, 6) of cylindrical design, the container axis (2) of which is aligned essentially in the vertical direction. Provided in the interior of the container is a rotatable plate (13), fastened on an axially guided shaft (12), for distributing compound (5) fed into the container (1, 6), as well as a thin-layer degassing system (14) which can be heated and cooled and degasses the compound (5) fed by the distributing plate (13). A stirrer homogenizes the degassed compound collected in the interior of the container. The thin-layer degassing system (14) occupies the major part of the space present between the shaft (12) and the wall of the container (1, 6). The stirrer has stirring arms (19, 20), which are fastened to the distributing plate (13) and are led into the bottom region of the container (1, 6) and which engage behind the thin-layer degassing system (14) on that side facing away from the distributing plate (13). The device has a high throughput of compound and, given suitable level control, can be operated with feed through.
