Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Behufs Filtrirzwecke sind schon, mehrfach gebrannte Massen aus Kieseiguhr oder aus Asbest in Verbindung mit organischen oder anorganischen Substanzen hergestellt worden.For the purpose of filtering purposes are already, several times Burned masses from Kieseiguhr or from asbestos in connection with organic or inorganic substances have been produced.
Auch sind schon Mischungen aus Kieseiguhr und Asbest bekannt geworden, welche jedoch nur in ungebranntem Zustande als Isolirmaterial Verwendung finden sollen.Mixtures of Kieseiguhr and asbestos have also become known, but there are some should only be used as insulating material in the unfired state.
Vorliegende Erfindung beruht im Wesentlichen darauf, ein Brenngut aus einer Mischung aus Kieseiguhr und Asbest herzustellen, um eine allen gewünschten Anforderungen entsprechende feste Filtrirmasse zu erzeugen, die vorzugsweise zum Filtriren von Trinkwasser oder anderen Flüssigkeiten dienen soll, welche möglichst keimfrei bezw. keimfrei gewünscht werden.The present invention is essentially based on a material to be fired from a mixture to manufacture from Kieseiguhr and asbestos to meet all requirements to produce solid Filtrirmasse, which should preferably be used for the Filtriren of drinking water or other liquids, which as germ-free or as possible. aseptic are desired.
Alle bisher bekannten Filtrirmassen entsprechen nicht den gewünschten Anforderungen, da infolge ihrer Zusammensetzung besonders eine fortschreitende Verstopfung der Poren und demgemäfs ein fortschreitendes Sinken ihrer quantitativen Leistung stattfindet.All previously known filter media do not meet the desired requirements, because of their composition especially a progressive clogging of the pores and accordingly there is a progressive decline in their quantitative performance.
Um diese Uebelstände zu vermeiden, mufs die Masse besondere, bisher nicht erreichte physikalische Eigenschaften besitzen, und zwarIn order to avoid these evils, the mass must be special, not yet reached possess physical properties, namely
a) möglichst zahlreiche und gleichmäfsige feine Poren, so dafs die kleinsten, festen Stoffe, selbst Bakterien sicher zurückgehalten werden, wobei es besonders darauf ankommt, dafs das Porenvolumen so grofs ist, dafs das Maximum der quantitativen Leistung bei vollendeter qualitativer erreicht wird;a) as numerous and even fine pores as possible, so that the smallest, solid substances, even bacteria are safely retained, and it is particularly important that this is the case The pore volume is so great that the maximum of the quantitative output is achieved when the pore volume is complete is achieved more qualitatively;
b) mufs die Masse frei von Haarrissen sein, eine Bedingung, welche beim Brennen von Kieseiguhrmasse sehr schwer zu erfüllen ist;b) The mass must be free of hairline cracks, a condition which occurs when burning Kieseiguhrmasse is very difficult to meet;
c) mufs die Festigkeit der Masse eine ganz bestimmte sein. Für die Haltbarkeit der Masse ist hierbei die gröfste Festigkeit bezw. Härte erwünscht. Die vollkommene Reinigung der zur Filtration benutzten Fläche erfordert hingegen einen gewissen Grad von Weichheit der Masse. Eine vollkommene Reinigung ist nämlich nur zu erzielen, wenn eine ganz dünne Schicht der Oberfläche zugleich mit den abfiltrirten Schlickstoffen abgerieben wird. (Die Poren aller Filter, welche aus gebranntem Thon, Porzellanerde, natürlichem Sandstein, künstlichen Steinen u. s. w. hergestellt sind, setzen sich im Laufe des Gebrauches mehr und mehr zu; nach jeder Reinigung, sei es ,durch Abreiben oder Abspülung, bleibt ein gewisser Procentsatz der Poren verklebt, so dafs solche Filter in ihrer quantitativen Leistung beständig zurückgehen.) Sind die gebrannten Massen aus Kieseiguhr aber zu weich, so nutzt sich das Filter beim Reinigen zu schnell ab. Für die praktische Brauchbarkeit solcher Massen ist es mithin von gröfster Wichtigkeit, bei der Herstellung den richtigen Grad der Festigkeit zu treffen; c) the firmness of the mass must be quite definite. For the durability of the mass, the greatest strength is resp. Hardness desired. On the other hand, the complete cleaning of the surface used for filtration requires a certain degree of softness of the mass. Complete cleaning can only be achieved if a very thin layer of the surface is rubbed off at the same time as the filtered silt matter. (The pores of all filters, which are made of burnt clay, china clay, natural sandstone, artificial stones, etc., become more and more clogged in the course of use; after each cleaning, be it by rubbing or rinsing, a certain percentage remains Pores clogged up, so that such filters are constantly decreasing in their quantitative performance. For the practical usability of such masses it is therefore of the greatest importance to achieve the correct degree of strength during manufacture;
d) mufs das Brenngut für die mechanische Bearbeitung einen gewissen Grad von Zähigkeit haben, da die Brennkrusten, welche alle aus Kieseiguhr gebrannten Formstücke aufweisen — weil zu dicht und fest — entfernt werden müssen.d) The material to be fired must have a certain degree of toughness for mechanical processing because the burning crusts, which all have shaped pieces fired from Kieseiguhr - because too tight and tight - must be removed.
Alle diese für eine gut wirkende und haltbare Filtrirmasse erforderlichen Bedingungen, welche bei der Herstellung der bisher bekannten Filtrirmassen nicht erfüllt werden können, werden durch das vorliegende Verfahren sicherAll these conditions necessary for a well-functioning and durable filter mass, which cannot be met in the production of the previously known filter masses, become safe through the present procedure
