Description

Die Erfindung bringt ein neues Verfahren, um den seit über tausend Jahren bekannten Tonziegel ohne besondere Beimischung leicht und porös zu machen.The invention brings a new process that has been around for over a thousand To make clay bricks, known for years, light and porous without any special admixture.

Die Zeichnung stellt in skizzenhafter Weise die zu dem Verfahren erforderlichen Einrichtungen dar. i ist eine Einfüllvorrichtung (Schnecke) die gegen einen Überdruck arbeiten muß. a stellt ein geschlossenes Mischgefäß dar, mit Rührflügel 3, doppeltem Mantel q. für die Heizung, die mit Regel- und Kontrolleinrichtung 5 versehen ist, außerdem zeigt das Mischgefäß einen regelbaren Wasserzulauf sowie einen Auslaß 6, der für stufenweise Regelung eingerichtet ist. 7 stellt eine Vorrichtung zur Formgebung der Ziegel dar, 8 eine Transportanlage, 9 einen Trockentunnel mit seiner Heizeinrichtung io.The drawing is a sketchy representation of the equipment required for the process. I is a filling device (screw) that must work against excess pressure. a represents a closed mixing vessel, with agitator 3, double jacket q. for the heating, which is provided with a regulating and monitoring device 5, the mixing vessel also has a controllable water inlet and an outlet 6 which is set up for step-by-step regulation. 7 represents a device for shaping the bricks, 8 a transport system, 9 a drying tunnel with its heating device io.

Durch die Schnecke i wird trockener Ton in das Mischgefäß 2 geschafft. Erfindungsgemäß wird der Ton in dem Gefäß 2 mit Heißwasser (über ioo° C) zu einem Brei angerührt und weiter erhitzt, bis in der Trommel e ein gewisser Überdruck herrscht und die Temperatur des Tonbreis gleich der diesem Druck entsprechenden Dampftemperatur ist. Erfindunggemäß tritt nun dieser heiße, unter Druck stehende Tonbrei durch die mit einer stufenweisen Regelung versehenen Öffnung 6 ins Freie. Durch die Druckabnahme wird ein Teil der in dem Tonbrei enthaltenen Wärmeenergie frei und bewirkt, daß sich die im Brei enthaltenen Wasserteilchen in Dampf verwandeln, der Tonbrei wird schaumig. Dieser schaumige Brei wird nun bei seiner hohen Temperatur in die Form gestrichen und auf einem Förderband im Tunnel 9 vorgetrocknet, wobei erfindungsgemäß 'die Temperatur im Tunnel so hoch liegt, daß die im schaumigen Tonbrei herrschende Dampfspannung nicht absinkt.Dry clay is fed into the mixing vessel 2 through the screw i. According to the invention, the clay in the vessel 2 becomes one with hot water (over 100 ° C.) Mix the pulp and continue heating until there is a certain overpressure in the drum e and the temperature of the clay pulp is equal to the steam temperature corresponding to that pressure is. According to the invention, this hot, pressurized clay slurry now passes through the with a gradual regulation provided opening 6 to the outside. By the decrease in pressure a part of the thermal energy contained in the clay pulp is released and causes the water particles contained in the pulp transform into steam, which becomes clay pulp frothy. This foamy pulp is now in the mold at its high temperature painted and predried on a conveyor belt in the tunnel 9, according to the invention 'The temperature in the tunnel is so high that that prevailing in the foamy clay pulp Steam tension does not decrease.

Der vorgetrocknete Ziegel wird nun in bekannter Weise im Ofen gebrannt.The pre-dried brick is then kilned in the known manner.
