Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Filter für streubares Filtermaterial, bei' denen durch das unter seinem natürlichen Böschungswinkel gelagerte Filtermaterial Hohlräume begrenzt werden, sind in der Praxis nur dann verwendbar, wenn die zu filtrierende Flüssigkeit eine durch die Schwere des Filtermaterials begrenzte geringe Durchflußgeschwindigkeit hat. Wird diese überschritten, dann wird das Filtermaterial anFilter for scatterable filter material, at ' those through the filter material stored at its natural angle of repose Cavities are limited, can only be used in practice if the to filtering liquid has a low flow rate limited by the gravity of the filter material Has. If this is exceeded, the filter material is activated
ίο den Austrittsflächen durch die Strömung aufgelockert und mit der zu filtrierenden Flüssigkeit fortgeschwemmt.ίο the exit surfaces by the flow loosened and washed away with the liquid to be filtered.
Ist dagegen das Filtermaterial nur auf einer Seite unter seinem natürlichen Böschungswinkel gelagert, während es auf der anderen Seite durch Siebe mit genügend feiner L'ochung gestützt ist, so daß es nicht ausweichen kann, so kann die Flüssigkeit, sobald ihre Geschwindigkeit eine bestimmte Grenze überschreitet, nur in einer Richtung hindurchgeleitet werden, bei der das Sieb die Austrittsseite darstellt. Bei umgekehrter Stromrichtung muß auch der vorerwähnte Übelstand wieder auftreten. Ein weiterer Ubelstand der Filter letzterer Art ist aber dadurch bedingt, daß sich das Filtermateria'l unmittelbar gegen die Siebfläche legt und teilweise in die Sieblöcher eindringt, wodurch diese verstopft werden und der Austritt der Flüssigkeit erschwert wird, und zwar Um so mehr, je feiner das Filtermaterial und je größer der durch die Materialsäule gegen das Sieb erzeugte Druck ist.If, on the other hand, the filter material is only below its natural one on one side Angle of repose stored, while it is on the other hand through sieves with enough is supported by a fine hole so that it cannot escape, so the liquid, as soon as their speed exceeds a certain limit, only in one direction are passed through, in which the sieve is the outlet side. With the reverse In the direction of the current, the above-mentioned inconvenience must also reappear. Another disadvantage of the filter of the latter type is due to the fact that the filter material lies directly against the screen surface and partially penetrates the sieve holes, thereby clogging them and the outlet the liquid is more difficult, the more the finer the filter material and the greater the pressure generated by the column of material against the screen.
Die erwähnten Übelstände möglichst zu vermeiden, ist Zweck der vorliegenden Erfindung. Diese besteht darin, daß die Hohlräume, die in bekannter Weise durch das unter seinem natürlichen Böschungswinkel gelagerte Filtermaterial mit den dasselbe stützenden Flächen α gebildet werden, durch an die Flächen α anschließende Siebe b abgeschlossen sind. Hierdurch wird verhindert, daß das Filtermaterial, auch bei erhöhter Strömungsgeschwindigkeit der Flüssigkeit, mit dieser fortgeschwemmt werden kann. Die Lage der Siebe b kann beliebig, horizontal, vertikal oder geneigt sein. Ebenso kann die Entfernung zwischen Filtermaterial und Sieben beliebig groß gewählt werden. Man hat es nun vollkommen in der Hand, die Strömungsgeschwindigkeit so zu regeln, daß entweder die Sieblöcher ganz frei bleiben und die Flüssigkeit unbehindert hindurchlassen, oder daß das Filtermaterial nur gelockert wird und sich mit leichtem Druck gegen die Siebflächen legt. In jedem Falle ist die Höhe der Filtermaterialsäule ohne Einfluß. Die Stromrichtung der Flüssigkeit kann beliebig sein.The purpose of the present invention is to avoid the above-mentioned inconveniences as much as possible. This consists in that the cavities, which are formed in a known manner by the filter material supported at its natural angle of repose with the surfaces α supporting the same, are closed off by sieves b adjoining the surfaces α. This prevents the filter material from being able to be washed away with the liquid, even if the flow rate of the liquid is increased. The position of the sieves b can be arbitrary, horizontal, vertical or inclined. The distance between the filter material and the sieves can also be selected as large as desired. It is now completely up to you to regulate the flow rate in such a way that either the sieve holes remain completely free and the liquid can pass through unhindered, or that the filter material is only loosened and gently presses against the sieve surfaces. In any case, the height of the filter material column has no effect. The direction of flow of the liquid can be any.
Fig. ι der Zeichnung stellt ein Filter dar, bei welchem die Stützflächen α geneigt und die Siebe b vertikal angeordnet sind. DieFig. Ι of the drawing shows a filter in which the support surfaces α are inclined and the sieves b are arranged vertically. the
Fig. 2 und 4 zeigen für geneigt angeordnete Stützflächen α horizontale bezw. geneigte Siebe b. In Fig. 3 ist ein Filter dargestellt, bei dem das Filtermaterial einerseits durch ein durchlaufendes Sieb c unmittelbar gestützt wird, während es andererseits unter seinem natürlichen Böschungswinkel gelagert ist und mit den vertikalen Stützflächen a und den geneigt liegenden Sieben b geschlossene Hohlräume bildet. Auch hier ist die Strömungsrichtung der Flüssigkeit beliebig und von der Filterkonstruktion unabhängig. Fig. 2 and 4 show for inclined support surfaces α horizontal respectively. inclined sieves b. In Fig. 3 a filter is shown in which the filter material on the one hand is directly supported by a continuous sieve c , while on the other hand it is mounted at its natural angle of slope and forms closed cavities with the vertical support surfaces a and the inclined sieves b. Here, too, the direction of flow of the liquid is arbitrary and independent of the filter design.
