KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das Bestreben, Verbesserungen an dem unter dem Namen Fachfilterpresse bekannten Filterpressensystern zu treffen, wurde vorwiegend durch die, so unverhältnifsmäfsig schnell vor sich gehende Abnutzung der eigentlich wirksamen Bestandtheile, das sind die Filtertücher, veranlafst. Sehr viele Verbesserungen zielten demnach auf Entfernung der Filtertücher und Ersatz derselben durch andere Mittel ab.The endeavor to improve the filter press system known as the specialist filter press to hit, was mainly due to the disproportionately rapid wear and tear of the actually effective ones Components, i.e. the filter cloths, are initiated. A great many improvements were aimed at on removing the filter cloths and replacing them by other means.
Die hier vorliegende Erfindung unterscheidet sich betreffs ihres Zieles wesentlich von den eben gekennzeichneten Bestrebungen auf dem Gebiete des Fachfilterpressenbaues. Sie strebt, unter Aufrechterhaltung des Princips der Filtration mittelst Filtertücher, eine Vergrößerung der Widerstandsfähigkeit und somit der Dauerhaftigkeit dieser Tücher an, und erreicht ihr Ziel durch Anwendung eines Conservirungsverfahrens, welches sich als von eigenthümlicher Wirkung auf die Tücher und die Filtrationsarbeit erweist. The present invention differs substantially from the US Pat efforts in the field of specialist filter press construction. She strives while maintaining the principle of filtration by means of filter cloths, an enlargement the resilience and thus the durability of these towels, and you achieve Aim through the use of a conservation process, which turns out to be more peculiar Has an effect on the cloths and the filtration work.
Unter Benutzung der Eigenschaft des Indigos, in gewissem Mafse conservirend auf Pflanzenfasern einzuwirken, wird das zur Herstellung der Filtertücher dienende Garn einer Färbung mit Indigo unterworfen. Dieser in der Färberei bekannte Farbstoff durchdringt und umgiebt die einzelnen Fasern des Garnes in einer solchen Weise, dafs sie für den schädlichen Einflufs der in Filterpressen vorkommenden Säuren, scharfen Laugen aller Art weniger empfindlich werden.Using the property of indigo to act to a certain extent conservatively on vegetable fibers, this becomes the production the yarn used for filter cloths is subjected to dyeing with indigo. This one in the dye works known dye penetrates and surrounds the individual fibers of the yarn in such a Way that they are responsible for the harmful influence of the acids found in filter presses, sharp lyes of all kinds become less sensitive.
Das hiermit gekennzeichnete neue Verfahren wirkt in dem Mafse vortheilhaft auf die Tücher ein, dafs in der Weise conservirte Tücher eine lange Zeit in Benutzung gelassen werden können, gegenüber Filtertüchern gewöhnlicher Art, welche häufig nur wenige Tage in gebrauchsfähigem Zustande zu bleiben vermögen.The new process thus identified has the same beneficial effect on the wipes one that cloths preserved in this way can be left in use for a long time, compared to filter cloths of the usual type, which are often only usable for a few days To be able to stay in a state of affairs.
