Description
Das Patent 9I9408 betrifft eine vorzugsweise für Filter zur Wasseraufbereitung verwendete einstellbare Filterdüse, welche dadurch gekennzeichnet ist, daß die Düsenglocke heruntergezogen ist und die Schlitzbreite zu der Unterkante der Düsenglocke und dem Düsenboden einstellbar ist. The patent 9I9408 relates to one preferably for filters for water treatment used adjustable filter nozzle, which is characterized in that the nozzle bell is pulled down and the slot width to the lower edge of the nozzle bell and the nozzle base is adjustable.
Bei derartigen Düsen kann es vorkommen, daß mit Rücksicht auf die sehr kleine Körnung des Filtermaterials der einstellbare Spalt so klein gehalten werden muß, daß der DurchfluBwiderstand sehr groß wird. Durch die vorliegende Erfindung wird der Erfindungsbereich dieser Düse dadurch wesentlich erweitert, daß man im Düsenmantel parallel zum Düsenboden einen oder mehrere Schlitze anbringt, deren Breite von vornherein so klein ist, daß keine Gefahr besteht, daß Filtermaterial in dieselben eindringen kann. Dadurch, daß man diese Spalte möglichst nahe an den Düsenboden anbringt, wird erreicht, daß die Spülluft bzw. With such nozzles it can happen that with regard to the very small grain size of the filter material the adjustable gap is kept so small must be that the flow resistance is very large. Through the present invention the scope of the invention of this nozzle is significantly expanded by the fact that in Nozzle jacket attaches one or more slots parallel to the nozzle bottom, whose Width is so small from the start that there is no risk of filter material can penetrate into them. By keeping this column as close as possible to the Attaches the nozzle bottom, it is achieved that the purge air resp.
Regenerierflüssigkeit auch die untersten Schichten des Filtermaterials intensiv durchdringt.Regenerating liquid also the lowest layers of the filter material penetrates intensely.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt. An exemplary embodiment is shown in the drawing.
Abb. I zeigt eine Filterdüse im Schnitt und Abb. 2 eine eingeschraubte Filterdüse, deren Nippel aus einer durchbohrten Schraube besteht. Fig. I shows a section of a filter nozzle and Fig. 2 shows a screwed-in one Filter nozzle, the nipple of which consists of a cannulated screw.
Im unteren Teil der Düsenglocke 2 sind auf den Umfang verteilt parallel zum Düsenboden6 verlaufende Schlitze IO angeordnet. In the lower part of the nozzle bell 2 are distributed parallel to the circumference Slits IO extending to the nozzle bottom6 are arranged.
