device for the manufacture of a fließfähigen, foam ausreagierenden mixture from fließfähigen components

摘要

In the production of a flowable mixture of flowable components which reacts to form a foam, deposition is avoided during the gas treatment of at least one of the components in a pressure tank (11) by means of a hollow stirrer (20), which simultaneously serves for the continuous circulation of the component in the pressure tank (11), by providing the intake opening (23) of the hollow stirrer (20) outside the pressure tank (11) and by connecting said opening to the gas space (47) of the pressure tank (11) via a gas line (46) in which a shut-off valve (48), which if appropriate is automatically operable, is arranged so that the hollow stirrer (20) can run continuously but the gas treatment process can be interrupted.
