Description
Verfahren zur Herstellung von Filtersteinen durch Brennen geformter Gemische von Syenit, Ton und Kieselgur.Process for the production of filter stones shaped by firing Mixtures of syenite, clay and diatomaceous earth.
Die Erfindung betrifft eine besondere Ausführungsform des bekannten Verfahrens zur Herstellung von Filtersteinen durch Brennen geformter Gemische von Syenit, Ton und Kieselgur. The invention relates to a particular embodiment of the known Process for the production of filter stones by firing shaped mixtures of Syenite, clay and diatomaceous earth.
Die Herstellung von Filtersteinen war von jeher eine vielbebandelte Aufgabe und hat seit der Erkenntnis der Gefährlichkeit von Aliliroorganismen eine Schwierigkeit dadurch erfahren, daß man von dem Filterstein verlangte, er sollte nicht nur in dem Wasser schwebende Fremdkörper mineralischen oder auch organischen Ursprunges, sondern auch Mikroorganismen zurfickhalten. Daneben gingen Forderungen hinsichtlich der Leistungsfähigkeit der Filtersteine und ihrer mechanischen Festigkeit und Bearbeitungsfähigkeit. The manufacture of filter stones has always been a very busy one Task and has had a Experiencing difficulty by asking the filter stone to be not only mineral or organic foreign bodies floating in the water Origin, but also hold back microorganisms. There were also demands regarding the performance of the filter stones and their mechanical strength and machinability.
Der Zweck der vorliegenden Erfindung ist, einen Filterstein zu schaffen, der bei ausreichender Leistung keimfrei filtriert und dabei genügend fest und bearbeitungsfähig ist. Zur Beschaffung eines derartigen Filters ist es aber nicht ausreichend, die genannten Ausgangsmaterialien entsprechend zu wählen, sondern sie müssen auch in einem bestimmten hiengenverhältnis verwendet und unter den richtigen Bedingungen gebrannt werden. The purpose of the present invention is to create a filter stone, which, with sufficient performance, filters germ-free and is sufficiently firm and workable is. To obtain such a filter, however, it is not sufficient that the to choose the starting materials mentioned accordingly, but they also have to be in used in a certain relationship and under the right conditions to be burned.
Nach der Erfindung wird ein den Forderungen hinsichtlich Leistung und mechanischer Festigkeit und Bearbeitungsfäbigkeit genügender und dabei, wie durch Versuche nachgewiesen wurde, alle Mikroorganismen auffangenden, also keimfrei filtrierender Filterstein dadurch erhalten, daß man 4 bis 6 Teile Syenit, 3 bis 4 Teile Ton und I Teil Kieselgur vermischt und die daraus in bekannter Weise geformten Gegenstände bei heller Rotglut (800 bis goo0 C) brennt. According to the invention, one of the requirements for performance and mechanical strength and machinability more sufficient and how It has been proven by tests to capture all microorganisms, i.e. germ-free filtering filter stone obtained by adding 4 to 6 parts of syenite, 3 to 4 parts of clay and I part of kieselguhr mixed and molded from it in a known manner Objects burned in bright red heat (800 to goo0 C).
Das richtige Mischungsverhältnis ist sehr wesentlich. Nimmt man z. B. zu viel Kieselgur oder Syenit, so wird die Masse wenig plastisch und gibt keinen guten Filterstein, nimmt man zu wenig Kieselgur, so filtriert der Stein schlecht. The correct mixing ratio is very important. If you take z. B. too much kieselguhr or syenite, the mass is not very plastic and gives none good filter stone, if you take too little kieselguhr, the stone filters poorly.
Durch das angegebene Mischungsverhältnis (4 bis 6 Teile Syenit, 3 bis 4 Teile Kaolin, I Teil Kieselgur) jedoch erhält man eine gut plastische Masse, die sich wie Ton in Formen bringen läßt, und durch das Brennen der Formlinge bei verhältnismäßig niedriger Temperatur (helle Rotglut) erhält man Filtersteine von ausreichender Leistungsfähigkeit mit so feinen Poren, daß sie Mikroorganismen nicht durchlassen. Außerdem - wird die Masse beim Brennen so fest. daß man auch schwachwandige Rohre aus ihr bilden kann. The specified mixing ratio (4 to 6 parts Syenit, 3 up to 4 parts kaolin, 1 part kieselguhr), however, a good plastic mass is obtained, which can be shaped like clay, and by firing the moldings filter stones are obtained from at a relatively low temperature (bright red heat) sufficient capacity with pores so fine that they cannot contain microorganisms let through. Besides - becomes the crowd when burning so tight. that you can also make thin-walled pipes from it.
