Description

Mischvorrichtungen, bei denen einer in einer Rohrleitung fließenden Flüssigkeit über eine Dosierpumpe eine andere Flüssigkeit über ein System von parallelgeschalteten Lochdüsen zugemischt wird, sind bekannt. Sie haben den Nachteil, daß bei Verstopfung einer oder mehrerer Lochdüsen zwar die zugemischte Flüssigkeitsmenge durch den steigenden Druck der Dosierpumpe praktisch konstant bleibt, jedoch durch die schlechtere Vertei­ lung die Mischqualität beeinträchtigt wird. Will man diese Störung beheben, muß die Verstopfung der Lochdüsen mechanisch beseitigt werden.Mixers where one in one Liquid flowing through a pipeline Dosing pump another liquid over a System of perforated nozzles connected in parallel are known. They have the disadvantage that if one or more perforated nozzles become blocked the admixed amount of liquid by increasing pressure of the dosing pump practically constant remains, but due to the poorer distribution mixing quality is impaired. If you want to remedy this problem, the constipation must the perforated nozzles are mechanically eliminated.

Die vorliegende Erfindung vermeidet diesen Nachteil dadurch, daß die parallelgeschalteten Lochdüsen im Falle einer Verstopfung durch einen Drehschieber einzeln und nacheinander mit der Dosierpumpe verbunden werden, so daß verstopfte Düsen durch den nun ansteigenden Druck der Dosierpumpe freige­ spült werden können.The present invention avoids this disadvantage characterized in that the perforated nozzles connected in parallel in the event of blockage by a rotary valve individually and one after the other with the dosing pump be connected so that clogged nozzles through the now release increasing pressure of the dosing pump can be rinsed.

Die Abbildung zeigt eine mögliche Ausführung dieser Er­ findung mit 3 Lochdüsen.The figure shows a possible execution of this Er with 3 perforated nozzles.

Durch das Mischrohr 1 fließt die Hauptflüssigkeit. In dem Mischrohr befindet sich das Düsen­ rohr 2 mit den Lochdüsen 3, 4 und 5. In dem Düsenrohr ist der Drehschieber 6 drehbar gelagert mit den Löchern 7, 8, 9, 10, 11 und 12. Die zugemischte Flüssigkeit wird durch die Bohrung 13 in den Hohlraum 14 des Drehschiebers 6 geleitet und von dort auf die Lüchdüsen 3, 4 und 5 verteilt. Die Teilschnitte a-a, b-b und c-c zeigen die Anordnung der Bohrungen im Düsenrohr 2 und im Drehschieber 6.The main liquid flows through the mixing tube 1 . In the mixing tube there is the nozzle tube 2 with the perforated nozzles 3, 4 and 5 . The rotary valve 6 is rotatably mounted in the nozzle tube with the holes 7, 8, 9, 10, 11 and 12 . The mixed liquid is passed through the bore 13 into the cavity 14 of the rotary valve 6 and from there distributed to the Lüchdüsen 3, 4 and 5 . The partial sections aa, bb and cc show the arrangement of the bores in the nozzle tube 2 and in the rotary valve 6 .

In der gezeichneten Darstellung fließt die zugemischte Flüssig­ keit gleichmäßig durch alle drei Lochdüsen 3, 4 und 5. Im Störungsfall durch Verstopfen einer oder mehrerer Düsen, der durch den erhöhten Druck der zugemischten Flüssigkeit ange­ zeigt wird, wird der Drehschieber 6 über seinen Antriebszap­ fen 15 zunächst um 90° im Uhrzeigersinn gedreht.In the illustration shown, the admixed liquid flows uniformly through all three perforated nozzles 3, 4 and 5 . In the event of a malfunction due to clogging of one or more nozzles, which is indicated by the increased pressure of the admixed liquid, the rotary valve 6 is first turned by its drive pin 15 by 90 ° clockwise.

Jetzt ist nur die Lochdüse 3 über die Bohrung 10 mit der zugemischten Flüssigkeit verbunden. Bei weiterer Drehung um 90° ist nur die Lochdüse 4 über die Bohrung 11 mit der zu­ gemischten Flüssigkeit verbunden und bei weiterer Drehung um 90° ist es die Lochdüse 5 über die Bohrung 12. Bei nochmaliger Drehung um 90° ist der gezeichnete Ausgangszustand wieder erreicht und die Störung behoben.Now only the perforated nozzle 3 is connected to the mixed liquid via the bore 10 . With a further rotation through 90 °, only the perforated nozzle 4 is connected to the liquid to be mixed via the bore 11 and with a further rotation through 90 ° it is the perforated nozzle 5 via the bore 12 . With a further rotation through 90 °, the drawn initial state is reached again and the fault is remedied.

Dieser Vorgang kann beispielsweise automatisch so ablaufen, daß bei auftretendem Störfall, angezeigt durch den erhöhten Druck der Dosierpumpe, der Drehschieber 6 um eine ganze Um­ drehung bewegt wird. Ist der Störfall dann noch nicht be­ seitigt, kann um mehrere volle Umdrehungen weitergefahren werden.This process can, for example, run automatically so that in the event of a malfunction, indicated by the increased pressure of the metering pump, the rotary valve 6 is moved by a whole rotation. If the malfunction has not yet been rectified, you can continue by several full revolutions.

Bei entsprechender Ausführung können auch zwei oder mehr als drei Lochdüsen verwendet werden.With a corresponding design, two or more can also be used can be used as three hole nozzles.

Claims (2)

1. Mischvorrichtung mit mehreren parallelgeschalteten Lochdüsen, dadurch gekennzeichnet, daß in einem Düsenrohr (2) mit den Lochdüsen (3), (4) und (5) ein Drehschieber (6) so angeordnet ist, daß er in seiner Normalstellung alle Loch­ düsen gleichzeitig mit der zugemischten Flüssigkeit versorgt aber durch je eine Teil­ drehung in der Lage ist, jede Düse auch einzeln nacheinander mit der zugemischten Flüssigkeit zu verbinden.1. Mixing device with a plurality of perforated nozzles connected in parallel, characterized in that in a nozzle tube ( 2 ) with the perforated nozzles ( 3), (4 ) and ( 5 ) a rotary slide valve ( 6 ) is arranged so that it nozzles in its normal position at the same time supplied with the mixed liquid but by rotating each part is able to connect each nozzle individually with the mixed liquid one after the other. 2. Mischvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß bei Verstopfung einer oder mehrerer Lochdüsen durch den dadurch ver­ ursachten erhöhten Druck der Dosierpumpe der Drehschieber (6) automatisch um eine oder mehrere volle Umdrehungen gedreht wird, bis die Verstopfung beseitigt ist.2. Mixing device according to claim 1, characterized in that in the event of blockage of one or more perforated nozzles by the increased pressure of the metering pump caused thereby, the rotary slide valve ( 6 ) is automatically rotated by one or more full rotations until the blockage is eliminated.
