Description

Strahlwäscher für das körnige Filtermaterial.Jet scrubber for the granular filter material.

Es sind Strahlwäscher für das körnige Filtermaterial in Filtern bekannt, bei denen neben dem Auslauf der Strahldüse ein Hilfsauslaß für das Treibmittel zu dem Zwecke angeordnet ist, das Filtermaterial rund um den Düsenauslauf in genügender Weise aufzulockern. Diese bekannten Hilfsauslässe haben aber einerseits den Nachteil, daß die Größe der wirksamen Durchtrittsöffnungen des Treibmittels verhältnismäßig klein ist und anderseits, daß sich diese Hilfsauslässe leicht verstopfen. Jet scrubbers are known for the granular filter material in filters, where in addition to the outlet of the jet nozzle an auxiliary outlet for the propellant too is arranged for the purpose, the filter material around the nozzle outlet in sufficient Way to loosen up. However, on the one hand, these known auxiliary outlets have the disadvantage that the size of the effective passage openings of the propellant is proportionate is small and, on the other hand, that these auxiliary outlets are easily clogged.

Diese überstände werden gemäß der Erfindung dadurch beseitigt, daß der Hilfsauslaß durch ein senkrechtes, vorzugsweise zylinderförmiges Sieb großer Oberfläche abgedeckt ist, das nach Art eines Nasensiebes mit schräg nach abwärts gerichteten und daher der Verstopfungsgefahr sehr wenig ausgesetzten Öffnungen - versehen ist. These overhangs are eliminated according to the invention in that the auxiliary outlet through a vertical, preferably large cylindrical screen Surface is covered, which is like a nasal sieve with an incline downwards directed and therefore very little exposed to the risk of clogging - is provided.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung an einem Strahlwäscher, dessen Strahldüse durch ein oberhalb eines festen Sandfängers liegendes Ventil abschließbar ist. Naturgemäß ist die Erfindung aber auch anwendbar auf andere Strahlwäscher mit abweichend gestalteten Abschlußeinrichtungen für diesStrahldüse. The drawing illustrates an embodiment of the invention on a jet scrubber, the jet nozzle of which passes through a fixed sand trap above lying valve is lockable. The invention is natural but also applicable to other jet scrubbers with differently designed locking devices for this jet nozzle.

Das Waschwasser wird einem zweiteiligen Krümmer 1 zugeführt, der in einem Aufsatz 2 die Strahldüse 3 trägt. Diese ist an ihrer der Treibmittelleitung 1 zugekehrten Öffnung durch einen Ventilkörper 4 abschließbar, der oberhalb eines fest eingebauten Sand fängers 5 liegt und dessen durch die Stopfbüchse 7 nach auswärts geführte Stange ihren Antrieb durch den an ihr bei 8 angelenkten Hebel 9 erfährt, der mittels des bei Ii am Gehäuse und bei 10 an dem Hebelg angelenkten Lenkers I2 geführt wird. The washing water is fed to a two-part manifold 1, the in an attachment 2, the jet nozzle 3 carries. This is on your propellant line 1 facing opening can be closed by a valve body 4 above a built-in sand catcher 5 is and its through the stuffing box 7 to the outside guided rod is driven by the lever 9 articulated to it at 8, by means of the link I2 articulated on the housing at Ii and on the lever at 10 to be led.

Der Aufsatz 2 ist von einem zylindrischen Nasensiebmantel I3 umgeben, der in einem Abstand von der Außenwand des Aufsatzes 2 liegt und dessen Öffnungen 14 schräg nach abwärts gerichtet und durch die nasenförmigen Ausdrückungen gegen das Eindringen von Sand geschützt sind. In den zwischen dem Nasensieb I3 und dem Aufsatz 2 gebildeten Raum wird durch den Kanal 15 von der Hilfsleitung I6 aus Wasser eingeführt, das sobald es durch die Sieböffnungen 14 ausge--treten ist, den Sand oberhalb der Düse 3 auflockert. Durch eine Öffnung 17 steht der Kanal 15 auch mit der Hauptleitung I des Treibmittels in Verbindung, so daß das Spülwasser je nach Bedarf aus der Hauptleitung I oder der Hilfsleitung I6 entnommen werden kann. The attachment 2 is surrounded by a cylindrical nasal sieve jacket I3, which is at a distance from the outer wall of the attachment 2 and its openings 14 directed obliquely downwards and by the nose-shaped expressions against the ingress of sand are protected. In the between the nasal strainer I3 and the Top 2 formed space is through the channel 15 of the auxiliary line I6 of water introduced, which as soon as it has emerged through the sieve openings 14, the sand loosens up above nozzle 3. The channel 15 also stands through an opening 17 the main line I of the propellant in connection, so that the rinse water depending on Need can be taken from the main line I or the auxiliary line I6.
