AUGUSTE TIXIER in BILLANCOURT, Frankr:AUGUSTE TIXIER in BILLANCOURT, France:
auf Grund der Anmeldung in Frankreich vom 21. Oktober 1908 anerkannt.recognized on the basis of the registration in France on October 21, 1908.
Vorliegende Erfindung betrifft ein Filter für Flüssigkeiten mit einer aus Sand bestehenden Filtermasse. Diese Filtermasse ist in bekann ter Weise durch eine aus jalousie- oder rostartig zusammengesetzten wagerechten Leisten gebildete schräg verlaufende Wand begrenzt, deren Öffnungen für den Eintritt der zu filternden Flüssigkeit dient. Die Roststäbe oder Jalousiestreifen sind in bekannter Weise mit ihren Breitseiten annähernd senkrecht gestellt, und ferner ist ebenfalls in bekannter Weise in einigem Abstand von der durchbrochenen Wand diese von einer vollen Wand überdeckt.The present invention relates to a filter for liquids having a filter made of sand Filter mass. This filter material is in a well-known manner by a shutter or grate-like composite horizontal strips limited sloping wall, whose openings are used for the entry of the liquid to be filtered. The grate bars or Blind strips are placed with their broad sides approximately perpendicular in a known manner, and furthermore is also in a known manner at some distance from the perforated Wall this covered by a full wall.
Die Erfindung besteht nun darin, daß nicht, wie bei den bekannten Filtern dieser Art, das Herausspülen von Sand aus der jalousieartig durchbrochenen Wand durch diese bedeckende gelochte Bleche verhindert wird und daß durch einstellbare Ventile, ζ. B. Klappen, der zwischen den beiden schrägen Wänden liegende Kanal verschlossen werden kann. Durch das Hindurchführen eines Wasserstromes durch den Kanal von oben nach unten, z. B. beim Entleeren dieses Kanales, kann hierdurch der obere Teil der zwischen den Stäben sich befindenden Sandschicht weggespült und so das Filter gereinigt werden.The invention consists in that not, as with the known filters of this type, the Rinsing of sand from the blind-like perforated wall through this covering perforated sheet metal is prevented and that adjustable valves, ζ. B. flaps between the two sloping walls lying channel can be closed. By leading through a flow of water through the channel from top to bottom, e.g. B. when emptying this channel, this can The upper part of the sand layer between the bars was washed away and so that Filter to be cleaned.
In der Zeichnung ist das Filter in einem Ausführungsbeispiel dargestellt.In the drawing, the filter is shown in one embodiment.
α ist der Behälter für das Rohwasser, b der Behälter für das Reinwasser. Die beiden Behälter sind durch eine Scheidewand c voneinander getrennt, unter welcher eine Durchgangsstelle d freigelassen ist. Eine von unten schräg ansteigende Wand e bildet am Boden der Anlage den kurzen Arm' eines U-Rohres, an welcher Stelle die Filtermasse sich ansammelt, wobei die Filtermasse gegen die Spülwirkung der strömenden Flüssigkeit durch eine Schotterauflagerung g geschützt werden kann. An der Rohwasserseite ist die Filtermasse f von einer gebogenen, aus nahezu senkrecht stehenden Stäben gebildeten jalousie- oder rostartigen Wand h bedeckt. α is the container for the raw water, b the container for the pure water. The two containers are separated from one another by a partition c , under which a passage point d is left free. A wall e rising at an angle from below forms the short arm of a U-tube at the bottom of the system, at which point the filter material collects, whereby the filter material can be protected against the flushing effect of the flowing liquid by a ballast layer g. On the raw water side, the filter material f is covered by a curved louvre or grate-like wall h formed from almost vertical rods.
Eine der Form der Filteroberfläche entsprechend gebogene Wand i, die nach der Zeichnung dem Rost h parallel verläuft, bildet eine Kammer für den Zutritt des Rohwassers zum Filter. Das Wasser tritt unten durch eine mittels Klappe j verschließbare Öffnung in die Kammer ein. Vom unteren Teil der Kammer führt ein Entleerungsstutzen I abwärts, der durch eine Klappe k zu verschließen ist, bei Verschluß der Klappe / erfolgt nach Öffnung der Klappe k eine Entleerung der Filterkammer, wobei sich aus dem Behälter b eine Rückströmung des Rein wassers einstellt, welche die Ablagerungen auf dem Rost h und A wall i, which is curved according to the shape of the filter surface and which runs parallel to the grate h according to the drawing, forms a chamber for the access of the raw water to the filter. The water enters the chamber at the bottom through an opening which can be closed by means of flap j. From the lower part of the chamber an emptying nozzle I leads downwards, which is to be closed by a flap k , when the flap is closed / after the flap k is opened, the filter chamber is emptied, with the pure water flowing back from the container b, which the deposits on the grate h and
dem Filterbrett entfernen und durch den Stutzen I, der zu einem Klärbehälter führen kann, fortspült.remove it from the filter board and wash it away through the nozzle I, which can lead to a septic tank.
Zum Ersatz des bei der Spülung mitgerissenen Sandes ist eine entsprechende Nachfüllung erforderlich, welche durch die obere öffnung m des Filters vorzunehmen ist.To replace the sand entrained during flushing, a corresponding refill is required, which is to be carried out through the upper opening m of the filter.
Die Filtermasse ruht auf einer Unterlage,' welche von den beiden geneigten Wänden e The filter mass rests on a base, 'which e
ίο und« gebildet wird, an deren tiefster Stelle eine verschließbare Entleerungsöffnung ο angebracht ist und durch welche die gesamte Filterfüllung herausgespült werden kann. Die Leistung des Filters ist abhängig von der Höhe der wirksamen Wassersäule, d. h. von der Differenz der Wasserspiegel in den beiden Behältern b und a. Diese Differenz vergrößert sich während des Betriebes nach Maßgabe der allmählichen Verunreinigung des Filters. Der veränderliche Höhenunterschied der Wasserspiegel läßt sich in einfacher Weise dazu benutzen, um eine selbsttätig wirkende Einrichtung zu schaffen, welche bei Erreichung einer bestimmten Maximaldifferenz durch Umstellung der Klappen / und k eine Reinigung in der erläuterten Weise vornimmt.ίο and «is formed, at the lowest point of which a closable drainage opening ο is attached and through which the entire filter filling can be flushed out. The performance of the filter depends on the height of the effective water column, ie on the difference in the water level in the two tanks b and a. This difference increases during operation in accordance with the gradual contamination of the filter. The variable difference in height of the water level can be used in a simple manner to create an automatically acting device which, when a certain maximum difference is reached, carries out cleaning in the manner explained by changing the flaps / and k.
