Abstract

Ein Mischer zum Herstellen pumpfähiger Putzmassen aus Trockenmasse und Anmachwasser umfaßt ein Mischrohr (1), das eine Mischwendel (11) auf einer Mischwelle (12) umschließt. Letztere endet in einem Mitnehmer (13) für die Schnecke (21) einer dem Mischrohr (1) nachgeordneten Schneckenpumpe (2). Eine verbesserte Homogenisierung der so erzeugten Putzmassen läßt sich dadurch erreichen, daß im Naßbereich des Mischrohres (1) mindestens ein Stauring (161) angeordnet ist. Letzterer ist vorzugsweise drehfest mit der Mischwelle (12) verbunden.

Figure 00000001
A mixer for producing pumpable plasters from dry matter and mixing water comprises a mixing tube (1) which surrounds a mixing spiral (11) on a mixing shaft (12). The latter ends in a driver (13) for the screw (21) of a screw pump (2) arranged downstream of the mixing tube (1). Improved homogenization of the plasters produced in this way can be achieved by arranging at least one retaining ring (161) in the wet area of the mixing tube (1). The latter is preferably non-rotatably connected to the mixing shaft (12).
