Description
Die Erfindung betrifft eine Filtervorrichtung für trockene, gasförmige und zum Teil funkenführende Medien. Beim Einsatz von solchen Filtervorrichtungen besteht die Gefahr, dass die bei diesen Filtervorrichtungen verwendeten Filterelemente durch Funkenflug Feuer fangen und sich entzünden können, insbesondere bei Anlagen zur Absaugung von Laser-Schneid-Anlagen. The invention relates to a filter device for dry, gaseous and partially spark-carrying media. When using such filter devices, there is a risk that the filter elements used in these filter devices can catch fire and ignite due to flying sparks, especially in systems for extracting laser cutting systems.
Es sind Umlenkeinrichtungen für gasförmige Medien in Form von Zyklonen bekannt, mit Hilfe derer Funken aus dem Luftstrom abgeschieden und dadurch eliminiert werden können. Derartige Zyklone haben den Nachteil, dass sie sehr gross bauen. Auch ist der bei ihrem Betrieb auftretende Druckverlust unerwünscht hoch.There are known deflection devices for gaseous media in the form of cyclones, with the help of which sparks can be separated from the air flow and thus eliminated. Such cyclones have the disadvantage that they are very large. The pressure loss that occurs during their operation is also undesirably high.
Es sind ferner Umlenkeinrichtungen in Form von Prallblechen bekannt. An diesen Prallblechen sollen die in dem Gasstrom enthaltenen Funkenteilchen durch Kontakt mit dem jeweiligen Prallblech soviel Energie verlieren, dass sie erlöschen. Der Wirkungsgrad solcher Prallbleche oder vergleich-barer Umlenkbleche ist wenig wirkungsvoll.Deflection devices in the form of baffle plates are also known. The spark particles contained in the gas flow are supposed to lose so much energy through contact with these baffle plates that they are extinguished. The efficiency of such baffle plates or comparable deflection plates is not very effective.
Es sind Vorrichtungen bekannt, unser Gebrauchsmuster 299 05 549.3 "Rotationsabscheider" vom 26.3.99. Als Vorabscheider und Funkenlöscher ist hier ebenfalls ein Horizontalzyklon vorgesehen.Devices are known, our utility model 299 05 549.3 "Rotational separator" dated March 26, 1999. A horizontal cyclone is also provided here as a pre-separator and spark extinguisher.

Der Unterschied besteht darin:The difference is:
Die Austragung des Staubes erfolgt über eine Schällippe über die Länge der Zylinderwand.The dust is removed via a peeling lip along the length of the cylinder wall.
♦ Der ausgetragene Staub wird in einem separaten Gefäss aufgefangen.♦ The discharged dust is collected in a separate container.
Der Zyklon ist einstufig.The cyclone is single-stage.
Die Zyklonwände sind parallel.The cyclone walls are parallel.
Ausgehend von dem Stand der Technik liegt der Erfindung die Aufgabe zugrunde:Based on the state of the art, the invention is based on the task:
a) eine Kompakteinheit zu schaffen, die auf kleinstem Raum die nachstehend aufgeführten Bauelemente beinhaltet.
Hierbei soll die Aussenhaut aus optischen Gründen glatt und ohne Vorsprung sein.a) to create a compact unit which contains the components listed below in the smallest possible space.
For optical reasons, the outer skin should be smooth and without any protrusions.
b) Die Vorabscheidung, d.h. die Funkenlöschung durch Vergrösserung der Kontaktflächen und der "Zyklonwirkung", soll verbessert werden.b) The pre-separation, i.e. the spark extinguishing by enlarging the contact surfaces and the "cyclone effect", should be improved.
c) Aus Wartungsgründen soll der Staub des Vorabscheiders wie auch des Feinfilters in ein Behältnis abgeworfen werden, d.h. es soll eine Lösung gefunden werden, dass nur ein Behältnis, bevorzugt Einwegbehälter, entsorgt werden muss.c) For maintenance reasons, the dust from the pre-separator and the fine filter should be thrown into a container, i.e. a solution should be found so that only one container, preferably a disposable container, has to be disposed of.
d) Des weiteren wurde gefordert, dass bei beschränkter Bauhöhe von 2000 - 2250 mm als Staubgefäss ein 200 Ltr. Normbehälter plaziert werden kann.d) Furthermore, it was required that with a limited construction height of 2000 - 2250 mm, a 200 litre standard container can be placed as a dust container.
Umwelttechnikenvironmental engineering
e) Die weitere Forderung war, das die Staubaustragestelle über ein Ventil geschlossen werden kann, so dass auch während des Betriebes die Staubbehältnisse gewechselt werden können.e) A further requirement was that the dust discharge point can be closed via a valve so that the dust containers can be changed even during operation.
f) Des weiteren wurde gefordert, dass das Staubbehältnis leicht transportiert werden kann und zwar auf Rollen oder mittels Gabelstapler.f) Furthermore, it was required that the dust container can be easily transported on rollers or by forklift.
Dieser Abscheider mit den vorstehend aufgeführten Eigenschaften ist in den Zeichnungsblättern 1, 2 und 3 dargestellt.This separator with the characteristics listed above is shown in drawing sheets 1, 2 and 3.
Zur Funkenlöschung und zur Abscheidung wärmeenergietragender Partikel ist dem Feinfilter ein ein- bzw. zweistufiger Horizontalzyklon (10) vorgeschaltet. Die staubbeladenen Gase treten tangential über den Stutzen (11) in die äussere Zyklonstufe, gebildet durch Zylinder (12) und (13) ein, durchströmen spiralförmig die 2. Zyklonstufe, gebildet durch Zylinder (13) und (14) und entweichen dann über das zentrische Tauchrohr (14) in das Feinfiltergehäuse (20).A one- or two-stage horizontal cyclone (10) is installed upstream of the fine filter to extinguish sparks and separate particles carrying heat energy. The dust-laden gases enter tangentially via the nozzle (11) into the outer cyclone stage, formed by cylinders (12) and (13), flow spirally through the 2nd cyclone stage, formed by cylinders (13) and (14), and then escape via the central immersion pipe (14) into the fine filter housing (20).
Durch die Rotationsströmung erfolgt eine intensive Wandberührung der gröberen Staubpartikel sowie eine Separation von Grob- und Feinstaub. Durch die Abgabe von Wärmeenergie an die Zyklonwand werden die Funken gelöscht. Die Konizität der Zyklonzylinder bewirkt einen besseren Staubtransport in der Grenzschicht in Richtung Staubaustrag.The rotational flow causes the coarser dust particles to come into intensive contact with the wall and separates coarse and fine dust. The release of heat energy to the cyclone wall extinguishes the sparks. The conicity of the cyclone cylinders improves dust transport in the boundary layer towards the dust discharge.
Über ein offenes Schlitzsegment (22) in Trennwand Filtergehäuse - Zyklon werden die wärmeenergietragenden grösseren Staubpartikel ausgetragen und separat über den Kanal (30) einem separaten Staubsammelgefäss (41) zugeführt, welches im grossen Staubbehälter (40) lose integriert ist.The larger dust particles carrying heat energy are discharged via an open slot segment (22) in the filter housing - cyclone partition wall and fed separately via the channel (30) to a separate dust collection container (41), which is loosely integrated in the large dust container (40).
Umwelttechnikenvironmental engineering
Der Feinstaub entweicht über das zentrische Tauchrohr (14) in das Feinfiltergehäuse (20). Das Feinfiltergehäuse ist mit Starrfilterkörpern (21) bestückt. Die Filterabreinigung erfolgt über Druckluftimpulse (23) im Gegenstrom. Der hier abgeschiedene Feinstaub fällt in den unten angeordneten Staubbehälter (40) ab und wird hier separat vom Grobstaub gelagert.The fine dust escapes through the central immersion pipe (14) into the fine filter housing (20). The fine filter housing is fitted with rigid filter bodies (21). The filter is cleaned using compressed air pulses (23) in countercurrent. The fine dust separated here falls into the dust container (40) located below and is stored there separately from the coarse dust.
Die gereinigten Gase entweichen über den nachgeschalteten Ventilator (50) und den Abluftkanal (60) mit Schalldämpfern (61) in den Arbeitsraum.The cleaned gases escape into the working area via the downstream fan (50) and the exhaust air duct (60) with silencers (61).
Der Staubbehälter (40) ist durch eine flexible Anpressvorrichtung (70) luftdicht mit dem Filtergehäuse (20) verbunden. Die Entkoppelung der Anpressvorrichtung (70) erfolgt mittels Stellhebel und Bowdenzug (71). Bei der Entkoppelung wird gleichzeitig ein Kegelventil (72) hochgedrückt und schliesst den Staubaustragestutzen (73), so dass zum Wechseln des Staubbehälters (40) die Absaug-Anlage nicht abgestellt werden muss.The dust container (40) is connected to the filter housing (20) in an airtight manner by a flexible pressure device (70). The pressure device (70) is decoupled using an adjusting lever and Bowden cable (71). During the decoupled process, a cone valve (72) is simultaneously pushed up and closes the dust discharge nozzle (73), so that the extraction system does not have to be switched off to change the dust container (40).
Der Staubbehälter (40), vorwiegend werden 200-Liter-Fässer als Einwegebehälter verwendet, ist auf einem fahrbaren Wagen (42) plaziert und in seiner Lage fixiert. Über eine Leitschiene (42a) wird die Lage des Wagens (42) für die Betriebsstellung positioniert. Nach Entkoppelung der Anpressvorrichtung durch Umlegen des Bedienhebels (71) kann der Wagen (42) mit dem Staubbehälter zur Wartung durch die Leitschiene leicht ein- und ausgefahren werden. Während dieser Zeit ist die Staubaustrittsöffnung (73) durch das Ventil (72) geschlossen.The dust container (40), mainly 200-litre drums are used as disposable containers, is placed on a mobile carriage (42) and fixed in position. The position of the carriage (42) for the operating position is positioned via a guide rail (42a). After uncoupling the pressing device by turning the operating lever (71), the carriage (42) with the dust container can be easily moved in and out for maintenance via the guide rail. During this time, the dust outlet opening (73) is closed by the valve (72).
Nach Einbringung des Staubwagens in die Betriebsstellung ist durch Umlegen des Stellhebels (71) der Staubbehälter wieder luftdicht mit dem Filtergehäuse verbunden. Gleichzeitig hat das Kegelventil (72) die Stauböffnung (73) wieder freigegeben.After the dust carriage has been brought into the operating position, the dust container is again connected to the filter housing in an airtight manner by turning the adjusting lever (71). At the same time, the cone valve (72) has released the dust opening (73) again.
Bei Einwegebehältern ist das integrierte Staubsammelgefäss (41) herausnehmbar, d.h. vor der Entleerung des grossen Behälters (40) oder vor der Neubestückung wird der kleine Behälter (41) nach oben herausgezogen. Dadurch, dass dieses Behältnis keinen Boden hat, fliesst der hier angesammelte Staub beim Herausnehmen in den grossen Behälter aus, so dass sich nur eine Entsorgungsstelle ergibt. Der neue oder entleerte Behälter wird dann wieder mit dem kleinen Behälter (41) bestückt. Die richtige Positionierung erfolgt durch eine Halterung (43), die an dem Adapter (44) befestigt ist.In disposable containers, the integrated dust collection container (41) is removable, i.e. before emptying the large container (40) or before refilling it, the small container (41) is pulled out upwards. Because this container has no bottom, the dust collected here flows out into the large container when it is removed, so that there is only one disposal point. The new or emptied container is then refilled with the small container (41). The correct positioning is achieved by a holder (43) that is attached to the adapter (44).

Zum Transport ist der Staubwagen (42) sowohl mit Rollen (45) als auch mit Staplerkufen (46) versehen. Als Haltegriff dient ein Bügel (47), in den ein Block (48) einrastet, der am Adapter (44) befestigt ist und so die Position für die Halterung (43) für den kleinen Behälter (41) fixiert.For transport, the dust cart (42) is equipped with both rollers (45) and forklift skids (46). A handle (47) serves as a handle, into which a block (48) snaps, which is attached to the adapter (44) and thus fixes the position for the holder (43) for the small container (41).
