A sweeper solving said problem has in combination the following parts: - a main mouth (9) with at least one nozzle (10) blowing from outside against the middle of the mouth and a suction pipe (12) located inside; - a secondary nozzle (15) with a suction conduit (17) movable with respect to the main mouth (9); - a common conduit (19) into which the two suction conduits (12, 17) open; - a coarse separator (23) arranged before a cyclone multiple separator (24, 25, 26); - a conduit (34, 35) supplying air from the cyclone on the suction side of a fan (3); - a separation piece (4) on the exhaust side of the fan for dividing exhausted air, and for supplying a portion of that air to the nozzle (10) blowing in the main mouth (9) and the other portion to a separator (38); and - an evacuation fan (45) arranged at the outlet of the separator (38).

Description

Die vorliegende Erfindung betrifft ein Fahrzeug mit Kehrmaschine, insbesondere zum Einholen von staubförmigem Material.The present invention relates to a vehicle with a sweeper, in particular for collecting dusty material.

Stand der TechnikState of the art

Es ist ein Reinigungsgerät bekannt geworden, welches sich insbesondere zum Reinigen von Strassen und Landebahnen von Flughäfen eignet. Dieses Gerät hat einen Aufnehmer mit zwei Aufnehmerdüsen, deren gegenseitige Lage starr ist. Die aufgenommenen Grobanteile gelangen zur Ausscheidung in einer quaderförmigen Kammer, in welcher mit steigendem abgelagertem Material die durchstreichende Luft wachsende Geschwindigkeiten aufweist und daher nicht nur der Luftwiderstand in der Kammer wächst, sondern insbesondere der Abscheidungsgrad schlechter wird. Dieser Zustand kann auch durch nachgeschaltete Siebe und Abzug eines Teilluftstromes mit Rückführung in die Kammer nicht verbessert werden. Mehrere, im Aufbau äusserst komplizierte, horizontal angeordnete, parallel geschaltete Fliehkraftabscheider können sich das Eigengewicht der Teilchen zum endgültigen Trennen von Luft und Teilchen nicht zu Nutze machen. Das ungezügelte führungslose Ausströmen der Abluftströme aus den Zyklonen in und durch eine längliche Kammer und die durch keine Wände in ein Sauggebläse zweimal brüsk um je 90° umgelenkte Abluft tragen zur Verringerung der Strömungsverluste und der Leistungsverminderung des Antriebs wenig bei. Dieses Reinigungsgerät ist wegen seines komplizierten Aufbaus in jeder Beziehung unwirtschaftlich (DE-OS 1 924 054).A cleaning device has become known which is particularly suitable for cleaning streets and runways at airports. This device has a sensor with two sensor nozzles, the mutual position of which is rigid. The coarse fractions taken up are discharged into a cuboid chamber, in which, as the deposited material rises, the air passing through has increasing speeds and therefore not only does the air resistance in the chamber increase, but in particular the degree of separation deteriorates. This condition cannot be improved even by downstream screens and extraction of a partial air flow with recirculation into the chamber. Several, extremely complex, horizontally arranged, parallel centrifugal separators can not take advantage of the weight of the particles for the final separation of air and particles. The unbridled, uncontrolled flow of the exhaust air flows from the cyclones into and through an elongated chamber and the exhaust air, which is deflected twice briskly by 90 ° through no walls into a suction fan, make little contribution to reducing the flow losses and reducing the performance of the drive. This cleaning device is uneconomical in every respect because of its complicated structure (DE-OS 1 924 054).

Eine weitere Ausführungsart eines Sauggerätes für Staub, Späne, Kehricht und andere Abfälle, weist einen Aufnehmer in Form einer seitlich abgerundeten quaderförmigen Kammer auf, aus deren Deckelmitte eine schlitzförmige Saugdüse mit Leitung zu einem ersten Fliehkraftabscheider führt.Another embodiment of a suction device for dust, chips, rubbish and other waste has a sensor in the form of a laterally rounded cuboid chamber, from the center of which a slot-shaped suction nozzle with a line leads to a first centrifugal separator.

Vorn und hinten in der Kammer mündet je eine Schlitz-Blasdüse aus dem Deckel in die Kammer. Zwischen Blasdüsen und Zyklon befindet sich ein Gebläse, wobei von der Düsenleitung - d.h. von der Druckleitung vom Gebläse - eine Zweigleitung mit einem Feinabscheider und Regelventil abzweigt.In the front and in the back of the chamber, a slot blow nozzle opens out of the lid into the chamber. There is a blower between the blowing nozzles and the cyclone, whereby from the nozzle line - i.e. from the pressure line from the blower - a branch line with a fine separator and control valve branches off.

Dieses Sauggerät ist zwar im Aufbau sehr einfach, jedoch bezüglich Wirkung für Feinstäube kaum genügend; denn im Aufnehmer befindet sich nur eine einzige Düse. Auch ist die Luftaufteilung in Umluft und Abluft zu unbeweglich, da die Umluft nur indirekt und nicht zwangsläufig - z.B. mittels eines weiteren Gebläses - veränderbar ist. Daher ist dieses Sauggerät, als zu wenig wirkungsvoll für die Lösung der vorliegenden Aufgabe, unzweckmässig (FR-PS 1 057 157)The construction of this suction device is very simple, but it is hardly sufficient in terms of its effectiveness for fine dust; because there is only one nozzle in the sensor. The air distribution in the recirculating air and exhaust air is too immobile, since the recirculating air is only indirect and not inevitable - e.g. by means of another fan - is changeable. This suction device is therefore unsuitable because it is not effective enough to solve the problem at hand (FR-PS 1 057 157)

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 die 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 Seitenringdüse 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 aussermittig angeordnet) die mit Alustaub beladene Luft ab. Neben dem Hauptmundstück 9 ist eine Nebendüse 15 mit einem Trichter 16 und einem Saugkanal 19 vorgesehen, der beweglich, z.B. als Schlauchrohr, ausgebildet 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 einem Zyklon-Einlaufstück 22 fort. In diesem befindet sich ein sich drehendes, z.B. motorgetriebenes Trennschaufelrad 23. Dieses bremst die groben Teile wie Papier, Gesichtsmaskenteile o. dgl. ab, während die Transportluft durch die Lochblechschaufeln 21 mit dem 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 Zyklon-Abzugsstück 34, das in eine Gebläse-Saugleitung 35 übergeht, die in den Saugstutzen des Gebläses 3 führt. Über die Wirkungsweise dieses Multiklons werden hier keine Einzelheiten beschrieben, wie die Aufteilung der Luft, die spiralförmige Zuführung in die Zyklone, die Tiefe der Tauchrohre, als Abzugsrohr bezeichnet, u. dgl., da diese grundsätzlich zum Stande der Technik gehören.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 The conveying air is divided by means of a flap 8 which can be pivoted about the 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 middle 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 continues in a cyclone inlet piece 22. In this there is a rotating, for example motor-driven, separation paddle wheel 23. This brakes the coarse parts such as paper, face mask parts or the like, while the transport air is hardly obstructed by the perforated sheet metal blades 21 with the aluminum dust, distributed over three cyclones 24, 25 and 26 becomes. The coarse particles are emptied through the channel 27, while the fine particles which are separated out in the multiclon are collected in the collecting bunker 26 and discharged from there. The three cyclones are 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 leads into the suction port of the blower 3. About the mode of operation of this multiclone, no details are described here, such as the division of the air, the spiral feed into the cyclones, the depth of the immersion tubes, referred to as the exhaust tube, and the like. Like., Since these are fundamentally part of the prior art.

Der Nebenkanal 7 führt zu einem Schlauchfilter 38 mit einer Kammer 39 und einem Austritt 40. In der Kammer 39 sind bekannterweise Filtersäcke 41 nebeneinander, und gegebenenfalls hintereinander, aufgehängt. Das anfallende Feinpulver wird am Austritt 40 entladen, während die Abluft durch einen Abluftkanal 43 in ein Abluftgebläse 45 führt, das die praktisch von Aluminiumstaub gereinigte Luft in die Atmosphäre ausbläst. Auch über das Schlauchfilter 38 werden keine näheren Einzelheiten bekanntgegeben, wie beispielsweise das automatische Reinigen durch Schütteln der Filtersäcke, deren Auswechseln, die Verwendung der entsprechenden Gewebe usw. - da diese zum Stande der Technik gehören -. In Fig. 5 ist ein Vierradfahrzeug 50 mit einem Führerstand 52 und einer Brücke 53 ersichtlich, auf welchem das Gebläse 3, das Hauptmundstück 9 sowie die Nebendüse 15 ersichtlich sind. Ferner ist der Sammelbunker 28 mit den Zyklonen schematisch dargestellt sowie der Schlauchfilter 38 mit den innengelegenen Filtersäcken, das ganze Vierradfahrzeug 50 mit dem Führerstand 52 und der Brücke 53. Ferner ist eine Antriebsgruppe 55, die auch in den Fig. 2-4 ersichtlich ist, mit Hilfsaggregaten 57 gezeichnet. Die Nebendüse 15 ist aufgrund des beweglich ausgeführten Saugkanals 17 - z.B. in Schlauchform - 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. Ofenumrandungen, mit strichpunktierten Linien eingezeichnet sind.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 bags, their 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 filter bags inside, the entire four-wheel vehicle 50 with the driver's cab 52 and the bridge 53. Furthermore, a drive group 55, which can also be seen in FIGS. 2-4, drawn with auxiliary units 57. The secondary nozzle 15 is due to the movable suction channel 17 - e.g. in the form of a tube - arranged to be displaceable, the normal working position in FIG. 5 with a solid line, for sweeping niches with dashed lines and the cleaning position of raised heels, e.g. Oven borders are drawn with dash-dotted lines.
