Description
Es ist bekannt, Filterschläuche mit wandernden Spüldüsen abeureinigen. Bei einer senkrecht zur Schlauchachse liegenden, den Schlauch ringförmig umfassenden, geschlossenen Düse wird der Schlauch infolge des zwischen ihm und der Düse erforderlichen Anpreßdruckes auf einen kleineren Durchmesser als ober- und unterhalb der Ringdüse zusammengepreßt und dadurch das Schlauchmaterial sehr beansprucht. Hierbei können sich auch Falten in der Schlauchwand bilden. It is known to clean filter hoses with moving flushing nozzles. In the case of a tube that is perpendicular to the tube axis and encompasses the tube in a ring, closed nozzle is the hose as a result of the required between it and the nozzle Contact pressure to a smaller diameter than above and below the ring nozzle compressed and thereby the hose material is very stressed. Here you can wrinkles also form in the hose wall.
Um diesen Übelstand zu beseitigen, hat man vorgeschlagen, die Ringdüse in zwei gegeneinander federnde Halbkreisdüsen aufzuteilen. Dadurch wird der genannte Nachteil aber nur unvollkommen beseitigt und eine komplizierte Bauart verursacht, zumal die federnden Düsenhälften auch noch mit Spülluft versorgt werden müssen. Nach einem weiteuren Vorschlag ist der Düsenring in mehrere Teilstüabe: aufgeteilt, die in verschiedenen Querschnittsebenen des Schlauches gegeneinander versetzt angeordnet sind. Bei dieser bekannten Anordnung wird also in einer Ebene jeweils nur ein Teil des Schlauchumfanges beeinflußt. In order to remedy this drawback, it has been proposed to use the ring nozzle to be divided into two semicircular nozzles that spring against each other. This will make the said Disadvantage but only incompletely eliminated and causes a complicated construction, especially since the resilient nozzle halves also have to be supplied with purging air. According to another suggestion, the nozzle ring is divided into several parts: which are arranged offset from one another in different cross-sectional planes of the hose are. In this known arrangement, only one part is in each case in a plane the hose circumference influenced.
Die Erfindung bezieht sich auf die Weiterentwicklung einer derartigen Düse und besteht darin, daß das einstückige Düsenrohr einen zylindrischen Längsabschnitt des Schlauchmantels umschlingt, so daß in jeder Ebene senkrecht zur Schlauchachse nur ein Bruchteil des Schlauchumfanges nahezu punktförmig erfaßt wird. Dadurch wird eine größere Schonung des Schlauches bei gleichzeitig einfacher Bauweise erreicht. The invention relates to the further development of such a device Nozzle and consists in that the one-piece nozzle tube has a cylindrical longitudinal section of the hose jacket wraps around so that in each plane perpendicular to the hose axis only a fraction of the hose circumference is detected almost point-like. This will A greater protection of the hose with a simple construction at the same time.
Ein Düsenrohr dieser Art kann in verschiedener Form ausgebildet sein, z. B. als Wendel, die den Schlauchmantelabschnitt in einem Schraubengang umfaßt. Eine solche Wendeldüse ist nicht in sich geschlossen. Das ist aber der Fall, wenn das Düsenrohr nach Art eines Zylinderschnittes schräg zur Achse als Ellipse angeordnet ist. Das Düsenrohr kann auch zweimal auf- und absteigend um den Schlauchmantelabschnitt gelegt werden, wodurch sich eine Sattel- oder Wellenform ergibt. Ein mehrwelliges Düsenrohr ist bei größeren Schlauchdurchmessern vorteilhaft. Die Düsenrohre der einzelnen Schläuche können, wie üblich, zu einer Spülgruppe für mehrere Schläuche zusammengefaßt werden. A nozzle tube of this type can be designed in various shapes, z. B. as a helix that includes the hose jacket section in a screw thread. Such a spiral nozzle is not self-contained. But that's the case when the nozzle tube is arranged in the manner of a cylinder section at an angle to the axis as an ellipse is. The nozzle tube can also ascend and descend twice around the hose jacket section be laid, resulting in a saddle or wave shape. A multi-wave Nozzle tube is advantageous for larger hose diameters. The nozzle pipes of the As usual, individual hoses can be combined to form a rinsing group for several hoses be summarized.
