Stand der TechnikState of the art
Es sind Strassenreinigungsmaschinen bekannt (CH-PS 582 281) , die sich aber für das Einholen feiner Stäube in Industriebetrieben nicht eignen, da diese Stäube, z.B.

Industriestaubsauger kommt wegen derer viel zu geringen Leistung für das Einholen solcher Stäube in technischen Betrieben nicht in Frage.Street cleaning machines are known (CH-PS 582 281), but they are not suitable for collecting fine dusts in industrial plants, since these dusts, e.g. Aluminum dust, only whirled up, but not picked up and deposited. The use of so-called industrial vacuum cleaners is out of the question because of their far too low performance for collecting such dusts in technical companies.

Beschreibung der EinzelfigurenDescription of the individual figures
Fig. 1 zeigt das Schaltschema einer Anlage 1 für das Aufnehmen von Alustaub, mit dem pneumatischen und dem Abscheidungssystem. Im pneumatischen System ist ein Hauptgebläse 3 mit einem Druckstutzen 4 vorgesehen, der sich in einen Hauptkanal 6 und einen Nebenkanal 7 teilt. Die Aufteilung der Förderluft erfolgt mittels einer um eine Achse 5 schwenkbaren Klappe 8, die von Hand über ein Gestänge oder mittels eines Stellmotors verstellt werden kann. Der Hauptkanal 6 mündet in ein Hauptmundstück 9 und versorgt eine Seitenringdü- se 10 - es können auch mehrere, sich über mindestens einen Teil des Umfanges erstreckende Düsen sein - mit Druckluft, die den vorhandenen Staub gegen das Zentrum des Hauptmundstückes 9 bläst. Dort saugt ein Hauptrohr 12 mit einer Saugdüse 13 (mittig oder aus- sermittig angeordnet) die mit Alustaub beladene Luft ab. Neben dem Hauptmundstück 9 ist eine Nebendüse 15 mit einem Trichter 16 und einem Saugkanal 19 vorge- sehen, der beweglich, z.B. als Schlauchrohr, ausgebil¬ det ist. Der Saugkanal 17 und das Hauptsaugrohr 12 vereinigen sich in einen Gemeinschaftskanal 19, wobei im Zusammenschluss eine Einstellklappe 20 angeordnet ist, um die Luftmengen entsprechend abstimmbar zu gestalten. Der Gemeinschaftskanal 19 setzt sich in - 4 -Fig. 1 shows the circuit diagram of a system 1 for receiving aluminum dust, with the pneumatic and the separation system. In the pneumatic system, a main blower 3 is provided with a pressure port 4, which is divided into a main duct 6 and a secondary duct 7. The conveying air is divided by means of a flap 8 which can be pivoted about an axis 5 and which can be adjusted manually via a linkage or by means of a servomotor. The main channel 6 opens into a main mouthpiece 9 and supplies a side ring nozzle 10 - there may also be several nozzles extending over at least part of the circumference - with compressed air which blows the dust present against the center of the main mouthpiece 9. There, a main pipe 12 with a suction nozzle 13 (arranged in the center or off-center) sucks off the air laden with aluminum dust. In addition to the main mouthpiece 9, a secondary nozzle 15 is provided with a funnel 16 and a suction channel 19, which is designed to be movable, for example as a tube. The suction duct 17 and the main suction pipe 12 merge into a common duct 19, an adjustment flap 20 being arranged in the union in order to make the air quantities correspondingly adjustable. The community channel 19 is in - 4 -

Dieses bremst die groben Teile wie Papier, Gesichtsmaskenteile o. dgl. ab,' während die Transportluft durch die Lochblechschaufeln 21 mit dema cyclone inlet piece 22. In this there is a rotating, for example, motor-driven impeller 23. This slows Trenn¬ o the coarse parts such as paper, facial mask parts. Like. Off 'while the transport air through the perforated plate 21 with the blades
Alustaub wenig behindert, auf drei Zyklone 24, 25 und 26 verteilt wird. Die Grobteile gelangen durch den Kanal 27 zur Entleerung, während die Feinteile, die im Multiklon ausgeschieden werden, im Sammelbunker 26 gesammelt und von dort abgeführt werden. Die drei Zyklone stecken in einem Sammelbunker 28. Die zentralen Absaugrohre 30, 31 und 32 der Zyklone 24, 25 und 26 münden in ein Zy¬ klon-Abzugsstück 34, das in eine Gebläse-Saugleitung 35 übergeht, die in den Saugstutzen des Gebläses 3 führt, üeber die Wirkungsweise dieses Multiklons wer¬ den hier keine Einzelheiten beschrieben, wie die Auf¬ teilung der Luft, die spiralförmige Zuführung in die Zyklone, die Tiefe der Tauchrohre, als Abzugsrohr be¬ zeichnet, u.dgl., da diese grundsätzlich zum Stande der Technik gehören.Little dust, aluminum dust is distributed over three cyclones 24, 25 and 26. The coarse parts are emptied through the channel 27, while the fine parts which are separated out in the multiclon are collected in the collecting bunker 26 and discharged from there. The three cyclones are located in a collecting bunker 28. The central suction pipes 30, 31 and 32 of the cyclones 24, 25 and 26 open into a cyclone discharge piece 34, which merges into a blower suction line 35 which flows into the suction port of the blower 3 The operation of this multiclone does not describe any details here, such as the division of the air, the spiral feed into the cyclones, the depth of the immersion tubes, as the exhaust tube, and the like, since these are basically used for State of the art belong.
Der Nebenkanal 7 führt zu einem Schlauchfilter 38 mit einer Kammer 39 und einem Austritt 40. In der Kammer 39 sind bekannterweise Filtersacke 41 nebeneinander, und gegebenenfalls hintereinander, aufgehängt. Das anfallen¬ de Feinpulver wird am Austritt 40 entladen, während die Abluft durch einen Abluftkanal 43 in ein Abluftgebläse 45 führt, das die praktisch von Aluminiumstaub gereinig¬ te Luft in die Atmosphäre ausbläst. Auch über das Schlauchfilter 38 werden keine näheren Einzelheiten be¬ kanntgegeben, wie beispielsweise das automatische Rei¬ nigen durch Schütteln der Filtersacke, deren Auswech¬ seln, die Verwendung der entsprechenden Gewebe usw. - da diese zum Stande der Technik gehören-. In Fig. 5 ist ein Vierradfahrzeug 50 mit einem Führer¬ stand 52 und einer Brücke 53 ersichtlich, auf welchem das Gebläse 3, das Hauptmundstück 9 sowie die Neben¬ düse 15 ersichtlich sind. Ferner ist der Sammelbunker 28 mit den Zyklonen schematisch dargestellt sowie der Schlauchfilter 38 mit den innengelegenen Filtersacken, das ganze Vierradfahrzeug 50 mit dem Fahrerstand 52 und der Brücke 53. Ferner ist eine Antriebsgruppe 55, die auch in den Fig. 2 - 4 ersichtlich ist, mit Hilfsaggre- gaten 57 gezeichnet. Die Nebendüse 15 ist aufgrund des beweglich ausgeführten Saugkanals 17 - z.B. in Schlauch¬ form - ortsverschiebbar angeordnet, wobei die normale Arbeitsstellung in Fig. 5 mit ausgezogenem Strich, für das Kehren von Nischen mit gestrichelten Linien und die Reinigungslage von erhöhten Absätzen, z.B.The secondary duct 7 leads to a bag filter 38 with a chamber 39 and an outlet 40. In the chamber 39, filter bags 41 are known to be hung next to one another and, if appropriate, one behind the other. The resulting fine powder is discharged at the outlet 40, while the exhaust air leads through an exhaust air duct 43 into an exhaust air blower 45 which blows the air, which has been practically cleaned of aluminum dust, into the atmosphere. Also, no further details are disclosed about the bag filter 38, such as, for example, the automatic cleaning by shaking the filter bag, its replacement, the use of the corresponding tissue, etc. - since these are part of the prior art. 5 shows a four-wheel vehicle 50 with a driver's cab 52 and a bridge 53 on which the blower 3, the main mouthpiece 9 and the secondary nozzle 15 can be seen. Furthermore, the collecting bunker 28 with the cyclones is shown schematically, as well as the bag filter 38 with the internal filter bags, the entire four-wheel vehicle 50 with the driver's station 52 and the bridge 53. Furthermore, a drive group 55, which can also be seen in FIGS. 2-4, drawn with auxiliary units 57.
