Description

Die Erfindung betrifft eine Nebeldüseneinrichtung, in welcher eine Mehrmediendüse innerhalb einer Nebeldüsen­kuppel an einem Adapterkopf angebracht ist, der sie mit den Medienzuleitungen verbindet.The invention relates to a mist nozzle device in which a multi-media nozzle is attached to an adapter head within a mist nozzle dome and connects it to the media supply lines.

Derartige Sprühdüsen, die Wasser nebelartig fein vertei­len können, werden in Schüttgutförderanlagen oder ande­ren staubhaltigen Räumen zum Niederschlagen des Staubs verwendet.Such spray nozzles, which can distribute water in a mist-like manner, are used in bulk material conveying systems or other dust-containing rooms for the precipitation of the dust.

Eine besonders gut einstellbare Wasservernebelung er­zielt man, wenn man Druckluft über eine sogenannte Reso­nanzkammer ausströmen läßt und dann Druckwasser ein­spritzt. Es entweichen dann nebelartige Wasserschwaden, die in besonderer Weise das Niederschlagen der Stäube oder geruchhaltiger Aerosole erreichen.Water nebulization can be set particularly well if compressed air is let out through a so-called resonance chamber and then pressurized water is injected. Mist-like water vapor then escapes, which in a special way causes the dust or odorous aerosols to deposit.

Infolge der Feinheit der Wassertropfen sind diese sehr empfindlich gegen störende Luftströmungen. Es ist daher wichtig, die Luftströmung im Düsenbereich zu stabilisie­ren und zu vergleichmäßigen und andererseits die Nebel­schwaden richtungsmäßig so in den zu entstaubenden Raum hineinzuleiten, daß eine optimale Nebelschwadenvertei­lung und Bindung des Staubes erzielt wird.Due to the fineness of the water drops, they are very sensitive to disturbing air currents. It is therefore important to stabilize and equalize the air flow in the nozzle area and, on the other hand, to direct the mist into the space to be dedusted in such a way that an optimal mist distribution and binding of the dust is achieved.

Zusätzlich soll die Düse gegen Beschädigung durch grobe Materialsplitter geschützt und auf einfache und sichere Weise inspiziert sowie in die Anlagen ein- und ausgebaut und an das Druckluft- und Druckwassernetz angeschlossen werden können. Ferner soll das Zubacken der Düse und der Nebeldüsenkuppel mit gebundenem und ggf. aushärtendem Staub vermieden werden.In addition, the nozzle should be protected against damage from coarse material splinters and inspected in a simple and safe manner, and installed and removed in the systems and connected to the compressed air and pressurized water network. The baking of the nozzle and the mist nozzle dome with bound and possibly hardening dust should also be avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Adapterkopf um eine Achse verschwenkbar ist, die mit der durch den Kuppelmittelpunkt verlaufenden Düsenmittel­achse einen Winkel von 15 bis 45° bildet.This object is achieved in that the adapter head is pivotable about an axis which forms an angle of 15 to 45 ° with the nozzle center axis running through the center of the dome.

Weiterhin ist vorgesehen, daß die Schwenkachse mit der Kuppelmittelachse einen Winkel von 15 bis 45° bildet.It is also provided that the pivot axis forms an angle of 15 to 45 ° with the central dome axis.

Beide Winkel können dabei vorteilhaft ca. 30° betragen. Durch Verdrehen des Adapterkopfes kann die Düsenachse damit von 0 bis 60° gegenüber der Kuppelmittelachse verschwenkt werden. Durch Rückdrehen der Kuppel kann die Düsenachse in ihrer Ebene bleiben.Both angles can advantageously be approximately 30 °. By turning the adapter head, the nozzle axis can be swiveled from 0 to 60 ° with respect to the central axis of the dome. By turning back the dome, the nozzle axis can remain in its plane.

Zum gerichteten und von Querströmungen ungestörten Aus­tritt des Nebels kann vorteilhaft die Nebeldüsenkuppel eine Halbschale bilden, die einen zylindrischen Rand aufweist, der eine Länge von etwa 5 % des Kuppeldurch­messers besitzen kann.For directed and undisturbed exit of the mist, the mist nozzle dome can advantageously form a half-shell which has a cylindrical edge which can have a length of approximately 5% of the dome diameter.

Zum Entfernen von Ablagerungen kann weiterhin innerhalb der Kuppel eine vorzugsweise mit Druckluftstößen beauf­schlagbare Düse angeordnet sein, deren Mittelachse eben­falls auf den Kuppelmittelpunkt gerichtet ist und wobei die Luftdüse einen mit der Kuppelinnenfläche einen Ring­spalt bildenden Rand aufweisen kann, unter dem zusätz­lich tangential Luft entlang der Kuppelinnenfläche aus­treten kann und wobei die Luftdüse mit einer Druckluft­speicherkammer mit Schnellentlüftungsventil verbunden ist.To remove deposits, a nozzle can preferably be arranged inside the dome, the center axis of which is also directed towards the center of the dome and the air nozzle can have an edge that forms an annular gap with the inner surface of the dome, under which additionally tangential air emerges along the inner surface of the dome can and wherein the air nozzle is connected to a compressed air storage chamber with quick exhaust valve is.

Die Luftdüse selbst kann dabei aus einem elastischen Ma­terial bestehen, das bei Aufbau eines Innendruckes ein automatisches Öffnen sowohl der zentralen Düsenöffnung als auch des Ringspaltes erlaubt.The air nozzle itself can consist of an elastic material that allows automatic opening of both the central nozzle opening and the annular gap when an internal pressure is built up.

Die Nebeldüsenkuppel kann vorteilhaft dadurch besonders leicht ein- und ausbaubar sein, wenn sie einen Befesti­gungsflansch aufweist, der aus einem Flachring und einem den Flachring und die Kuppel verbindenden Haltekragen besteht. Vorzugsweise ist dabei der Haltekragen fest mit der Kuppel verbunden, z.B. verschweißt, und der Flachring mit dem Gehäuse oder einer Wand eines zu ent­staubenden Raumes verbindbar bzw. verbunden und der Hal­tekragen und der Flachring sind unter Verdrehen der Kup­pel gegeneinander verschwenkbar und fixierbar, z.B. durch Verschrauben.The mist nozzle dome can advantageously be installed and removed particularly easily if it has a fastening flange which consists of a flat ring and a retaining collar connecting the flat ring and the dome. The holding collar is preferably firmly connected to the dome, e.g. welded, and the flat ring can be connected or connected to the housing or a wall of a space to be dedusted, and the retaining collar and the flat ring can be pivoted and fixed relative to one another by rotating the dome, e.g. by screwing.

Eine Weiterbildung der Erfindung sieht vor, daß zwischen dem Flachring und dem Haltekragen eine elastische Klemm­manschette angeordnet ist. Hierdurch werden die Montage und das Ausrichten der Nebeldüseneinrichtung verein­facht.A further development of the invention provides that an elastic clamping sleeve is arranged between the flat ring and the holding collar. This simplifies the assembly and alignment of the mist nozzle device.

Eine bevorzugte Ausgestaltung der Klemmanschette kenn­zeichnet sich dadurch, daß diese einen am Haltekragen fixierbaren inneren Teil aus zwei Klemmbacken aufweist, mittels welcher der Haltekragen beidseitig faßbar ist und welche nach Einsetzen des Haltekragens versteifbar sind, sowie dadurch, daß die Klemmamschette einen den Flachring aufnehmenden äußeren Teil aus einer festen, nur im Endbereich elastischen Backe und einer gelenk­artig angeschlossenen Backe aufweist, deren Hauptachse schräg auf den zu haltenden umlaufenden Flachring weist und zum Einsetzen des Flachringes durch diesen nach innen drückbar und nach dem Einsetzen elastisch rück­ federbar ist. Zur Versteifung kann beispielsweise eine Kardeele eingedrückt werden, um die Manschette dauerhaft und dicht mit dem Haltekragen zu verbinden. Die gelen­kige Backe erlaubt ein leichtes Eindrücken der Kuppel in die Öffnung des Flachringes oder auch in eine unmittel­bar in ein Gehäuse geschnittene Öffnung, wenn dessen Wanddicke etwa der Dicke des Flachringes entspricht. Weiterhin wird so erreicht, daß die Kuppel nur mit ver­größertem Kraftaufwand wieder aus der Manschette heraus­genommen werden kann. Bei kreisrunder Gestaltung von Haltekragen, Flachring und Manschette kann damit die Nebeldüsenkuppel sehr einfach in jede beliebige Ver­drehungsstellung gebracht werden und in ihrer Stellung zu Optimierungszwecken der Austrittsrichtung der Nebel­schwaden korrigiert werden. Selbstverständlich kann die Manschette dabei auch so gestaltet sein, daß die gelen­kige Backe nicht außen sondern innen liegt.A preferred embodiment of the clamping collar is characterized in that it has an inner part which can be fixed to the holding collar and consists of two clamping jaws, by means of which the holding collar can be gripped on both sides and which can be stiffened after the holding collar has been inserted, and in that the clamping collar has an outer part which receives the flat ring comprises a fixed jaw, which is only elastic in the end region, and a jaw which is connected in an articulated manner, the main axis of which points obliquely to the circumferential flat ring to be held and for inserting the flat ring can be pressed inwards by this and elastically back after insertion is resilient. For stiffening, for example, a card flange can be pressed in to permanently and tightly connect the cuff to the retaining collar. The articulated jaw allows the dome to be easily pressed into the opening of the flat ring or into an opening cut directly into a housing if the wall thickness corresponds approximately to the thickness of the flat ring. It is also achieved that the dome can only be removed from the cuff again with increased force. With a circular design of the holding collar, flat ring and sleeve, the mist nozzle dome can be very easily brought into any rotational position and its position can be corrected to optimize the direction of exit of the mist. Of course, the cuff can also be designed so that the articulated jaw is not on the outside but on the inside.

Die Verdrehung des Adapterkopfes gegenüber den Medienzu­leitungen wird letztlich vorteilhaft dadurch ermöglicht, daß der Adapterkopf außerhalb der Kuppel wenigstens einen als um die Schwenkachse verdrehbarer Überwurfring ausgebildeten Anschlußteil aufweist und daß in den sich gegeneinander verdrehenden Flächen zwischen dem Anschluß­teil und dem Kopf mindestens einseitig Ringkanäle mit Randabdichtungen zur Mediendurchleitung in den verschie­densten Stellungen vorhanden sind.The rotation of the adapter head relative to the media supply lines is ultimately advantageously made possible in that the adapter head has at least one connecting part outside the dome, which is designed as a coupling ring which can be rotated about the pivot axis, and that in the mutually rotating surfaces between the connecting part and the head, ring channels with edge seals are provided on at least one side Media transmission in various positions are available.

Die erfindungsgemäße Nebeldüseneinrichtung ermöglicht in besonders einfacher Weise eine beliebige Ausrichtung des Sprühstrahles und sehr guten Zugang von außen, was den Einsatz der Nebeldüsenkuppel wesentlich verbessert, ohne daß ein großer Aufwand vorliegt.The mist nozzle device according to the invention enables the spray jet to be oriented in a particularly simple manner and very good access from the outside, which considerably improves the use of the mist nozzle dome without a great deal of effort.

Im folgenden werden drei Ausführungsbeispiele der Erfin­dung anhand von Zeichnungen näher erläutert. Es zeigen:

  • Figur 1 schematisch einen Teilschnitt durch eine Nebeldüseneinrichtung,
  • Figur 2 die Einrichtung gemäß Figur 1 mit einer zusätz­lichen Luft-Reinigungsdüse und
  • Figur 3 die Einrichtung in einer dritten Ausführung.
In the following three embodiments of the invention are explained in more detail with reference to drawings. Show it:
  • FIG. 1 schematically shows a partial section through a mist nozzle device,
  • Figure 2 shows the device of Figure 1 with an additional air cleaning nozzle and
  • Figure 3 shows the device in a third embodiment.

Gemäß den Zeichnungen besteht die Nebeldüseneinrichtung aus einer Kuppel 4 in Form einer Halbschale aus steifem Material, welche einen zylindrischen Rand 5 aufweist, dessen Länge etwa 5 % des Schalendurchmessers beträgt. Die Kuppel 4 ist mittels eines Haltekragens 12 und eines Flachringes 11 in der Wandung eines zu entstaubenden Raumes montiert.According to the drawings, the mist nozzle device consists of a dome 4 in the form of a half-shell made of rigid material, which has a cylindrical edge 5, the length of which is approximately 5% of the shell diameter. The dome 4 is mounted by means of a retaining collar 12 and a flat ring 11 in the wall of a room to be dusted.

Innerhalb der Kuppel 4 ist auf einem Adapterkopf 1 eine Mehrmediendüse 14 angeordnet, deren Mittelachse 3, d. h. die Austrittsrichtung des Sprühmittels, immer auf den Mittelpunkt 40 der Kuppel 4 gerichtet und gegenüber der Adapterachse in den vorliegenden Ausführungsbeispielen um einen Winkel α von etwa 30° versetzt ist. Der Adapter­kopf 1 ist um eine ebenfalls den Mittelpunkt 40 durch­dringende Achse 2 verschwenkbar, die mit der Kuppelmit­telachse 41 einen Winkel β von ebenfalls ca. 30° bildet. Andere Winkel α und β im Bereich zwischen 15 und 45° sind ebenfalls je nach Bedarf möglich.Within the dome 4, a multi-media nozzle 14 is arranged on an adapter head 1, the central axis 3, d. H. the exit direction of the spraying agent is always directed to the center 40 of the dome 4 and is offset by an angle α of approximately 30 ° with respect to the adapter axis in the present exemplary embodiments. The adapter head 1 can be pivoted about an axis 2 which also penetrates the center point 40 and which also forms an angle β of approximately 30 ° with the central coupling axis 41. Other angles α and β in the range between 15 and 45 ° are also possible as required.

Der Adapterkopf ist gegenüber seinen Anschlußteilen 13 verdrehbar und derart ausgebildet, daß auch in den ver­schiedensten Drehstellungen der Durchtritt der Medien, vorzugsweise Luft und Wasser, gewährleistet ist. Die entsprechende Ausbildung liegt im Belieben des Fach­manns, sie kann z. B. über Ringnuten oder Ringkanäle er­folgen, die randseitig abgedichtet sind. Die Gegenfläche braucht dann lediglich im Bereich der Kanalöffnung bzw. Nut einen Austritt aufzuweisen. Die Befestigung des Adapterkopfes 1 gegenüber den verdrehbaren Anschlußtei­len 13 kann dann über eine Mutter 13′ erfolgen.The adapter head can be rotated relative to its connecting parts 13 and is designed such that the passage of the media, preferably air and water, is ensured even in the most varied of rotational positions. The appropriate training is at the discretion of the specialist. B. via ring grooves or ring channels that are sealed on the edge. The counter surface then only needs to have an outlet in the region of the channel opening or groove. The attachment of the Adapter head 1 with respect to the rotatable connecting parts 13 can then be done via a nut 13 '.

Gemäß Figur 2 kann innerhalb der Kuppel 4 noch eine wei­tere Luftdüse 6 angeordnet sein, die hier aus elasti­schem Material besteht und eine zentrale Düsenöffnung 10 sowie einen an der Kuppelinnenfläche 7 anliegenden Rand aufweist, wobei sich beim Aufbau von Innendruck die zen­trale Düsenöffnung 10 öffnet und der Rand 5 von der Kup­pelinnenfläche unter Bildung eines Ringspalts abgehoben wird. Über diese Düse kann eine Entfernung von Ablagerun­gen und dergleichen erfolgen, wenn entsprechend Druck­luft, vorzugsweise in Stößen, zugeführt wird.According to FIG. 2, a further air nozzle 6 can be arranged within the dome 4, which here consists of elastic material and has a central nozzle opening 10 and an edge abutting the inner surface 7 of the dome, the central nozzle opening 10 opening when the internal pressure builds up and the Edge 5 is lifted off the inner surface of the dome to form an annular gap. Deposits and the like can be removed via this nozzle if compressed air, preferably in shocks, is supplied accordingly.

Figur 3 zeigt die Nebeldüseneinricht in einer Ausführung mit einer zwischen dem Haltekragen 12 und einer hier den Flachring ersetzenden, kreisförmig ausgeschnittenen Be­hälterwand 11′ angeordneten elastischen Klemmanschette 15. An ihrer dem Haltekragen 12 zugewandten Innenseite weist die kreisförmig umlaufende Manschette 15 zwei relativ stabile und weitestgehend starre Backen 16 auf, die zwischen sich eine Nut zur Aufnahme des äußeren Teils des Haltekragens 12 bilden. Zur Sicherung der Verbindung zwischen Haltekragen 12 und Manschette 15 kann zwischen deren Backen 16 nach Einsetzen des Haltekragens 12 beispielsweise eine Kardeele eingepreßt werden.FIG. 3 shows the mist nozzle device in an embodiment with an elastic clamping sleeve 15 arranged between the holding collar 12 and a circular cut-out container wall 11 'replacing the flat ring here. The circular sleeve 15 has two relatively stable and largely rigid on its inside facing the holding collar 12 Jaws 16, which form a groove between them for receiving the outer part of the holding collar 12. To secure the connection between the holding collar 12 and the sleeve 15, for example a card flange can be pressed in between their jaws 16 after the holding collar 12 has been inserted.

An ihrem äußeren Umfang besitzt die Manschette 15 zwei unterschiedlich gestaltete Backen 17 und 18, wobei die Backe 17 von ähnlicher Form und Dimensionierung ist wie die Backen 16, während die Backe 18 gelenkartig ausge­bildet ist und eine Hauptachse aufweist, die schräg auf den zu haltenden umlaufenden Rand des Flachringes 11 weist.On its outer circumference, the sleeve 15 has two differently shaped jaws 17 and 18, the jaw 17 having a shape and dimension similar to that of the jaws 16, while the jaw 18 is articulated and has a main axis which is inclined to the circumferential to be held Edge of the flat ring 11 has.

Durch die besondere Gestaltung der Manschette 15 wird erreicht, daß die komplette Nebeldüseneinrichtung mit Adapterkopf 1 und Kuppel 4 einschließlich des Haltekra­gens 12 mit der auf diesen aufgesetzten Manschette 15 von der einen Seite, d. h. in Figur 3 von links her, in die in dem Flachring 11 vorhandene kreisförmige Öffnung eingedrückt werden kann. Während des Eindrückens weicht die Backe 18 elastisch nach innen zurück, um nach dem Eindrücken wieder in ihre in der Figur 3 sichtbare Stel­lung elastisch zurückzufedern. Für ein Herausziehen der Nebeldüseneinrichtung ist eine wesentlich größere Kraft erforderlich, da nun für die Verformung der Backe 18 größere Kräfte aufzuwenden sind.The special design of the cuff 15 achieved that the complete mist nozzle device with adapter head 1 and dome 4 including the retaining collar 12 with the sleeve 15 placed thereon from one side, ie in FIG. 3 from the left, can be pressed into the circular opening provided in the flat ring 11. During the pressing-in, the jaw 18 resiliently retracts inwards, in order to spring back into its position visible in FIG. 3 after the pressing-in. A considerably greater force is required to pull out the mist nozzle device, since greater forces are now to be exerted for the deformation of the jaw 18.

Durch Drehung des Adapters und der gesamten Kuppel kann die Ausströmachse in weiten Grenzen verstellt werden, so daß eine optimale Verteilung des Nebels im Staubgehäuse erzielt wird, wobei jederzeit eine nachträgliche Anpas­sung oder Optimierung in Abhängigkeit vom Förderstrom oder von der Strömung der staubhaltigen Luft erreicht werden kann.By rotating the adapter and the entire dome, the outflow axis can be adjusted within wide limits, so that an optimal distribution of the mist in the dust housing is achieved, whereby a subsequent adjustment or optimization depending on the flow rate or the flow of dusty air can be achieved at any time .

Die Anschlüsse der Wasser- und Luftkanäle des Adapters an die Wasser- und Luftleitung sind so gestaltet, daß diese ihre Richtung beibehalten können, unabhängig von der Position der Adaptereinstellung.The connections of the water and air channels of the adapter to the water and air line are designed so that they can maintain their direction, regardless of the position of the adapter setting.
