Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Zur raschen Filtration trüber Flüssigkeiten ist es vorteilhaft, zuerst die groben und dann die feineren Trübungen abzuscheiden. Es ist daher zuerst eine locker gestopfte Filtermasse genügend, auf welche dann dichter gelagerte Filterschichten folgen.For the rapid filtration of cloudy liquids, it is advantageous to first use the coarse and then to separate the finer opacities. It is therefore first a loosely packed filter mass sufficient, which are then followed by more densely stored filter layers.

Da mit wachsender Dichte der Widerstand wächst und somit die Durchgangsgeschwindigkeit bezw. die Filtratmenge in der Zeiteinheit abnehmen würde, so muß die Filterflä'che proportional der Filtermassendichte zunehmen, um die gleiche Filtratmenge zu erhalten, die durch die lockere Filtermassenschicht geht.Because with increasing density the resistance increases and with it the speed of passage respectively the amount of filtrate would decrease in the unit of time, the filter area must be proportional increase the filter mass density in order to obtain the same amount of filtrate that is passed through the loose filter mass layer goes.

Dieses wird erzielt durch nachstehend beschriebenen Filterkörper, der in den Fig. 1 und 2 im senkrechten Schnitt bezw. Grundriß dargestellt ist.This is achieved by the filter body described below, which is shown in FIG and 2 respectively in vertical section. Floor plan is shown.

Der Filterkörper besteht aus einem aus feingelochtem Blech hergestellten Behälter a mit abnehmbarem Deckel b. Der Behälter α besitzt einen Eingangsstutzen c mit kegelförmiger Abdeckung d, unter welcher ungefähr in halber Höhe des Hohlkörpers α Bohrungen e nach außen führen.The filter body consists of a plate made of feingelochtem a container with removable lid b. The container α has an inlet connection c with a conical cover d, under which approximately halfway up the hollow body α holes e lead to the outside.

Die Abdeckung d überragt den Schaft des Eingangsstutzens c. Der Fuß des letzteren ist an seinem Umfang als Keilring ausgebildet.The cover d projects beyond the shaft of the inlet connection c. The foot of the latter is designed as a wedge ring on its circumference.

Das Hineinpressen des Filtermaterials in den Behälter α erfolgt in dem Rahmen g (Fig. 3 und 4) einer Presse C. The filter material is pressed into the container α in the frame g (FIGS. 3 and 4) of a press C.

Der Rahmen ist ungefähr doppelt so hoch als die Filterkörper und wird bis zum Rande mit breiförmiger Filtermasse gefüllt, worauf die Preßplatte h bis auf die Filterkörper niedergeschraubt wird.The frame is about twice as high as the filter body and is filled to the brim with pulp-shaped filter material, whereupon the pressure plate h is screwed down to the filter body.

Vermöge der konischen Abdeckung d wird beim Niedergehen der Preßplatte die über dem Eingangsstutzen stehende Filtermasse nach außen gegen die Wandung gepreßt, so daß hier eine dichte Schichtung der Filtermasse entsteht, während durch die Überdeckung die zentralen Masseschichten vom Druck entlastet sind und dennoch ihre erste lockere Schichtung behalten.By virtue of the conical cover d , when the pressure plate goes down, the filter material standing above the inlet nozzle is pressed outwards against the wall, so that a dense layering of the filter material is created here, while the cover relieves the pressure on the central layers of the material and yet their first loose layering keep.

Es wird also eine lockere zentrale Schichtung und eine nach außen zunehmende dichtere Lagerung der Filtermasse bei wachsender Filterfläche erzielt.So there will be a loose central stratification and an outwardly increasing density Storage of the filter mass achieved with increasing filter area.

Um ein dichtes Anlegen der Filtermasse gegen den Schaft und in die Ecken des Körpers α zu bewirken, ist der ringförmige Fuß desselben nach außen und innen keilförmig gestaltet. Hierdurch wird die Flüssigkeit gehindert, unfiltriert am Schaft des Eingangsstutzens herunterzulaufen.In order to bring about a tight application of the filter mass against the shaft and in the corners of the body α , the annular foot of the same is designed wedge-shaped outwards and inwards. This prevents the liquid from running down the shaft of the inlet connection unfiltered.

Um gleichmäßig gepreßte Filterkörper und damit gleichmäßiges Filtrieren zu erhalten, wird zweckmäßig eine größere Zahl von Körpern gleichzeitig in der Preßvorrichtung gepreßt. Die Körper werden in beliebiger Anzahl zu einem Gesamtfilter in geeigneter Weise an gemeinsamen Zugangsrohren vereinigt und die Deckel b gegen Herunterfallen gesichert.In order to obtain uniformly pressed filter bodies and thus uniform filtration, a larger number of bodies is expediently pressed simultaneously in the pressing device. The bodies are combined in any number to form an overall filter in a suitable manner on common access pipes and the cover b is secured against falling.
