Description

Filter mit körnigem Filtermaterial und einer aus Strahlrohr mit Spülschirm bestehenden Kreislaufwaschvorrichtung.Filters with granular filter material and one made of a jet pipe with a rinsing screen existing circuit washing device.

Die Erfindung betrifft ein Filter mit körnigem Filtermaterial und einer aus Strahlrohr mit Spülschirm bestehenden Kreislaufwaschvorrichtung. Um bei derartigen Filtern ein gleichmäßig gutes Filtrat zu erzielen und zu diesem Zweck das über den Spülschirm rieselnde Filtermaterial gleichmäßig im Filterraum zu verteilen, ist gemäß der Erfindung zwischen der Unterkante des Spülschirmes und der wirksamen Filteroberfläche ein Ringdach angeordnet, welches das darüberrieselnde Filtermaterial gleichmäßig verteilt. Zweckmäßig überdeckt dabei das Ringdach die ringförmige Ablaufrinne für die ausgewaschenen Verunreinigungen. The invention relates to a filter with granular filter material and a circuit washing device consisting of a jet pipe with a rinsing screen. To at such filters to achieve a uniformly good filtrate and for this purpose to distribute the filter material trickling over the washing screen evenly in the filter chamber, is according to the invention between the lower edge of the washing screen and the effective one Filter surface arranged a ring roof, which the filter material trickling over equally distributed. The ring roof expediently covers the annular drainage channel for the washed-out impurities.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung in senkrech tem Schnitt. The drawing illustrates an embodiment of the invention in vertical cut.

Das Waschwasser wird in bekannter Weise durch eine Düse 1 in das Strahlrohr 2 eingeführt, das an seinem unteren Ende von einem doppelkonischen Abienlçkörper 3 umgeben ist und das an seinem oberen Ende den Spülschirm 4 trägt. Unterhalb der Umfangskante dieses Spülschirmes ist ein Ringdach 5 angeordnet, dessen Scheitel zweckmäßig im wesentlichen senkrecht über der Eintrittsöffnung 7 des nur von geraden Halteblechen 6 durchs;etzten Raumes zwischen dem doppelkonischen Ablenkkörper 3 und dem konischen Boden 8 des Behälters 10 liegt, Das Filtrat wird abgezogen durch ein Sieb 9, welches den unteren Teil des Ablenkkörpers 3 bildet, und durch das Rohr II. Die die Zeichnung veranschaulicht, wird durch das Ringdach 5 das aus dem Strahlrohr 2 austretende Filtermaterial in zwei Ringströme zerteilt, wodurch auf der Oberfläche des Filtermaterials zwei Böschungen I2 gebildet werden. Da die zu filtrierende Flüssigkeit, ehe sie nach dem Ablauf g gelangt, stets die Ringöffnung 7 durchlaufen muß und die seitlichen Böschungsflächen des Filtermaterials im Querschnitt ungefähr auf einem Kreisbogen liegen, der um die Mitte der Öffnung 7 geschlagen wird, so sind die Wege, die die Flüssigkeit in dem ruhenden Filtermaterial zu durchlaufen hat, im wesentlichen alle gleich. Ein Einebnen der Oberfläche des Filtermaterials ist also nicht mehr nötig. Unterhalb des Ringdaches ist eine ringförmige Ablaufrinne 13 angeordnet, die durch das Ringdach 5 gegen eindringendes Filtermaterial geschützt ist und die ausgewaschenen Verunreinigungen sowohl an ihrer Innen- als auch Außenkante überlaufen läßt. Durch die Anordnung des Siebmantels g am unteren Teil des Ablenkkörpers 3 wird außerdem das Eintreten des Filtrates erleichtert, da auf diesem Siebmantel nicht wie bei der Anordnung im oberen Teil das Filtermaterial unter Druck aufruht. The washing water is in a known manner through a nozzle 1 into the Jet pipe 2 introduced, which at its lower end by a double-conical Abienlçkörper 3 is surrounded and which carries the rinsing screen 4 at its upper end. Below the A ring roof 5 is arranged on the circumferential edge of this flushing screen, its apex expediently essentially perpendicular to the inlet opening 7 of the straight line only Retaining plates 6 through the last space between the double-conical deflector 3 and the conical bottom 8 of the container 10 lies, the filtrate is drawn off through a screen 9 which forms the lower part of the baffle 3 and through the pipe II. Which the drawing illustrates, is through the ring roof 5 that from the jet pipe 2 exiting filter material divided into two ring currents, causing on the surface of the filter material two slopes I2 are formed. Since the liquid to be filtered, before it arrives after the sequence g, must always pass through the ring opening 7 and the lateral slope surfaces of the filter material in cross section approximately on one Arc, which is struck around the center of the opening 7, then are the paths, which the liquid in the filter material at rest has to pass through, essentially all the same. There is no longer any leveling of the surface of the filter material necessary. An annular drainage channel 13 is arranged below the ring roof, which is protected against penetrating filter material by the annular roof 5 and which washed-out impurities overflow on both their inner and outer edges leaves. The arrangement of the screen jacket g on the lower part of the deflector 3 the entry of the filtrate is also facilitated, since on this sieve jacket not as with the arrangement in the upper part, the filter material rests under pressure.
