Abstract

Es gibt eine Herstellung von Schaumbrei, bei der ein Mischgerät 11 mit einem Speicher 9 für Trockengut verbunden ist, mit einem Flüssigkeits-Anschlußstutzen 12 versehen ist und eine Abgabe von Anmachbrei aufweist, bei der ein Anschluß 3 für flüssiges Schäummittel, ein Anschluß 4 für Wasser und ein Anschluß 2 für Druckluft vorgesehen sind und bei der eine Pumpe 20 zum Drükken von Schaumbrei zu einer Abgabestelle 23 vorgesehen ist. Dabei ist es erwünscht, wenn sich auch dickflüssiger Schaumbrei erzeugen, d. h. an der Abgabestelle zur Verfügung stellen läßt. Dies ist erreicht, indem der Anschluß 3 für flüssiges Schäummittel, der Anschluß 4 für Wasser und der Anschluß 2 für Druckluft an einem Reinschaum-Erzeuger 1 vorgesehen sind, der einen Auslaß 5 aufweist, indem die Abgabe von Anmachbrei und der Auslaß von Reinschaum einer Mischeinrichtung 16, 17, 18, 19 zugeführt sind und indem die Pumpe 20 zwischen der Mischeinrichtung 19 und der Abgabestelle 23 vorgesehen ist. Es wird aus dem flüssigen Schäummittel, dem Wasser und der Druckluft ein Reinschaum kontinuierlich erzeugt, es wird der Reinschaum einem von Schäummittel noch freien Anmachbrei im Durchlauf pumpdruckfrei zugemischt und es wird der erzeugte Schaumbrei von diesem Mischvorgang zur Abgabestelle gepumpt.

Figure 00000001
There is a production of foam slurry, in which a mixer 11 is connected to a storage 9 for dry goods, is provided with a liquid connection piece 12 and has a delivery of mixing slurry, in which a connection 3 for liquid foaming agent, a connection 4 for water and a connection 2 for compressed air are provided and in which a pump 20 for pushing foam slurry to a delivery point 23 is provided. It is desirable if viscous foam slurry can also be produced, ie made available at the delivery point. This is achieved in that the connection 3 for liquid foaming agent, the connection 4 for water and the connection 2 for compressed air are provided on a clean foam generator 1 which has an outlet 5, by dispensing mixing paste and the outlet of clean foam of a mixing device 16, 17, 18, 19 are supplied and in that the pump 20 is provided between the mixing device 19 and the delivery point 23. A clean foam is continuously generated from the liquid foaming agent, the water and the compressed air, the pure foam is admixed to a mixing slurry that is still free of foaming agent in the passage without pump pressure, and the foam slurry produced is pumped from this mixing process to the delivery point.
