The other channel walls (12, 19 and 20) are closed. An exhaust carriage (1) engages with a connection piece (6) below the lip (7) and in this way produces a flow connection to the exhaust channel (22) from an exhaust device which normally hangs downwards. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Absaugen von gasförmigen Schadstoffen, insbesondere von Abgasen aus Verbrennungsmotoren, mit einem stationären Saugkanal, an dem ein Saugwagen mit Absaugeinrichtung verfahrbar angeordnet ist und wobei der Saugkanal geschlossene Ober-, Rück- und Unterwände sowie eine freigebbare Kanalseitenwand aufweist.The invention relates to a device for suctioning gaseous pollutants, in particular exhaust gases from internal combustion engines, with a stationary suction channel on which a suction truck with suction device is arranged to be movable and wherein the suction channel has closed top, rear and bottom walls as well as a releasable channel side wall.

Ein derartiger Saugkanal ist aus der DE-PS 29 28 519 bekannt, der in einer senkrechten Seitenwand Gliederelemente aufweist, die ineinandergreifen und von dem Saugwaren derart angehoben werden, daß die Seitenwand immer nur im Bereich des Saugwagens geöffnet ist. Ein Nachteil dieser von der Fachwelt als Kulissen-Saugkanal bezeichneten Vorrichtung besteht darin, daß sich die einzelnen Gliederelemente verkanten können, was zu Betriebsstörungen führen kann. Außerdem ist die Herstellung eines Kulissen-Saugkanals wegen der Vielzahl ineinandergreifender Gliederelemente verhältnismäßig aufwendig.Such a suction channel is known from DE-PS 29 28 519, which has link elements in a vertical side wall which interlock and are lifted by the suction goods in such a way that the side wall is only ever open in the area of the vacuum truck. A disadvantage of this device, referred to in the art as the backdrop suction channel, is that the individual link elements can tilt, which can lead to malfunctions. In addition, the production of a backdrop suction channel is relatively complex because of the large number of interlocking link elements.

Ein einfacherer Saugkanal ist aus der US-A-2 693 749 bekannt, welche einen von einem Rohr gebildeten stationären Kanal zeigt. Das Rohr ist etwa in 8-Uhr-Stellung mit einem Längsschlitz versehen, der normalerweise durch zwei gegeneinander gerichtete Dichtlippen verschlossen ist. Wird an den Saugkanal Unterdruck gelegt, so werden die Dichtlippen gegeneinander gezogen und verschließen den Saugkanal. Ein Saugwagen ist an dem stationären Saugkanal so montiert, daß er mit einem Übergangsstück zwischen die Dichtlippen greift und somit eine Strömungsverbindung von einer Absaugvorrichtung zum Saugkanal herstellt. Ein Nachteil dieses bekannten Saugkanals besteht darin, daß zwei Dichtlippen erforderlich sind, die sich bei zunehmendem Gebrauch verschleißen und daher ausgetauscht werden müssen.A simpler suction channel is known from US-A-2 693 749, which shows a stationary channel formed by a tube. The tube is provided with a longitudinal slot at about 8 o'clock, which is normally closed by two sealing lips facing each other. If negative pressure is applied to the suction channel, the sealing lips are pulled against each other and close the suction channel. A suction truck is mounted on the stationary suction channel in such a way that it engages with a transition piece between the sealing lips and thus establishes a flow connection from a suction device to the suction channel. A disadvantage of this known suction channel is that two sealing lips are required, which wear out with increasing use and therefore have to be replaced.

Aus der US-A-2 923 227 ist ferner bereits ein Abgas-Saugkanal bekannt, bei welchem der im Querschnitt viereckige Saugkanal an drei Seiten geschlossen ist, jedoch in seiner Oberseite einen Längsschlitz aufweist, der von einer Kautschukbahn abgedeckt wird. Unter die Kautschukbahn greift ein Saugwagen, der auf diese Weise die Kautschukbahn teilweise von dem Saugkanal abhebt und damit eine Strömungsverbindung von einer Absaugvorrichtung zum Saugkanal herstellt. Diese Absaugvorrichtung ist jedoch verhältnismäßig aufwendig, da eine mehrfache Umlenkung des Saugschlauches von unten nach oben und wieder nach unten in den Saugkanal und ein aufwendiger Mechanismus zum Abheben der Kautschukbahn erforderlich sind.From US-A-2 923 227 an exhaust gas suction channel is also already known, in which the suction channel, which is square in cross section, is closed on three sides, but has a longitudinal slot in its upper side, which is covered by a rubber sheet. Under the rubber web engages a suction trolley which in this way partially lifts the rubber web from the suction channel and thus establishes a flow connection from a suction device to the suction channel. However, this suction device is relatively complex, since a multiple deflection of the suction hose from bottom to top and back down into the suction channel and a complex mechanism for lifting the rubber sheet are required.

Es ist Aufgabe der Erfindung, die beim Stand der Technik auftretenden Nachteile zu vermeiden und einen einfachereren Abgas-Saugkanal zu schaffen.It is an object of the invention to avoid the disadvantages occurring in the prior art and to create a simpler exhaust gas suction channel.

Zur Lösung dieser Aufgabe dient eine Vorrichtung der eingangs genannten Art, welche dadurch gekennzeichnet ist, daß die Kanalseitenwand von unter 30° bis 60°, vorzugsweise etwa 45° zur Kanalunterwand geneigten Gitterstäben, Gitterrosten, Gittern, Lochplatten o.ä. gebildet ist, die auf ihrer Außenseite von einer hochschwenkbaren Lippe abgedeckt sind, und daß der Saugwagen mit einem kanalseitigen Anschlußstück unter die Lippe greift.To solve this problem, a device of the type mentioned above is used, which is characterized in that the channel side wall is inclined at below 30 ° to 60 °, preferably about 45 ° to the channel bottom wall, grids, grids, perforated plates or the like. is formed, which are covered on the outside by a pivotable lip, and that the suction car engages with a channel-side connector under the lip.

Anstelle von Gitterstäben oder Gitterrosten lassen sich auch andere Einrichtungen wie Gitter, Netze, Lochplatten o.ä. verwenden, sofern sie nur einen Strömungsdurchtritt vom Saugwagen zum Saugkanal gestatten und andererseits eine Auflage für die die Seitenwand verschließende Lippe bilden.Instead of bars or gratings, other devices such as grids, nets, perforated plates or the like can also be used. use, provided that they only allow a flow passage from the suction vehicle to the suction channel and on the other hand form a support for the lip closing the side wall.

Gemäß Erfindung ist somit der Saugwagen seitlich neben einem stationären Abgaskanal aufgehängt, und zwar zweckmäßigerweise in einem Rahmengerüst, das an seiner Oberseite Laufräder aufweist, welche in eigens dafür vorgesehenen Schienen laufen. Die Schienen sind auf an sich bekannte Weise an einer Gebäudedecke zu befestigen, beispielsweise an einem oder mehreren Hauptträgern. Der Schlauchwagen trägt an seiner Unterseite einen senkrecht nach unten hängenden Absaugvorrichtung und lenkt somit die Abgasströmung um 90° in den Saugkanal um.According to the invention, the suction vehicle is thus suspended laterally next to a stationary exhaust duct, expediently in a frame structure which has wheels on its upper side which run in rails provided for this purpose. The rails are to be fastened to a building ceiling in a manner known per se, for example on one or more main girders. The hose trolley has a suction device hanging vertically downwards on its underside and thus deflects the exhaust gas flow through 90 ° into the suction channel.

Vorzugsweise ist an der Unterseite des Saugkanals in der Nähe von dessen Kanalunterwand ein weiterer Lippenstreifen vorgesehen, welcher die Unterseite des Saugwagen-Anschlußstücks abdichtet.A further lip strip is preferably provided on the underside of the suction channel in the vicinity of the bottom wall of the channel, which seals the underside of the suction vehicle connector.

In einer weiteren Ausführungsform ist an die geneigte und von der erwähnten Lippe verschließbare Kanalseitenwand ein unter die Lippe greifendes Anschlußstück vorgesehen, welches in einen verfahrbaren weiteren Saugkanal übergeht. Der weitere Saugkanal befindet sich dabei etwa auf der Höhe des stationären Saugkanals und verläuft zweckmäßigerweise im rechten Winkel dazu, obgleich auch eine andere Winkelausrichtung möglich ist. Der verfahrbare Saugkanal ist wiederum zweckmäßigerweise mit einer geneigten Kanalseitenwand versehen, die von einer Lippe abgedichtet wird. Greift nun unter die Lippe des verfahrbaren Saugkanals ein verfahrbarer Saugwagen der zuvor erwähnten Art, so kann dessen Absaugvorrichtung praktisch jeden beliebigen Punkt innerhalb eines Rechtecks erreichen, welches durch die Länge des stationären und des verfahrbaren Saugkanals beschrieben wird.In a further embodiment, a connection piece which extends under the lip and which merges into a movable further suction channel is provided on the inclined channel side wall which can be closed by the lip mentioned. The further suction channel is located approximately at the level of the stationary suction channel and expediently runs at right angles thereto, although a different angular orientation is also possible. The movable suction duct is in turn expediently provided with an inclined duct side wall which is sealed by a lip. Now engages under the lip of the movable suction duct a movable suction vehicle of the aforementioned A rt, its suction can reach almost any point within a rectangle which is determined by the length of the stationary and movable suction channel described.

Die Erfindung wird im folgenden anhand von Figuren näher erläutert; es zeigen:

  • Figur 1 eine Seitenansicht eines Ausführungsbeispiels;
  • Figur 2 eine Vorderansicht auf das Ausführungsbeispiel gemäß Figur 1; und
  • Figur 3 ein weiteres Ausführungsbeispiel mit zum Hauptkanal rechtwinkelig angeordnetem zweiten Saugkanal.
The invention is explained in more detail below with reference to figures; show it:
  • Figure 1 is a side view of an embodiment;
  • Figure 2 is a front view of the embodiment of Figure 1; and
  • Figure 3 shows another embodiment with the second suction channel arranged at right angles to the main channel.

Figur 1 zeigt einen Saugkanal 22 mit horizontaler Kanaloberwand 12 und dazu paralleler Kanalunterwand 19, die zusammen mit einer die beiden Wände verbindenden Kanalrückwand 20 einen geschlossenen Kasten bilden. Gegenüber der Kanalrückwand 20 ist eine Kanalseitenwand 18 durch schräge Gitterstäbe 11 gebildet, welche die Kanalunterwand 19 mit der Kanaloberwand 12 unter einem Winkel von 300 bis 60° vorzugsweise unter 45° verbinden. Anstelle der Gitterstäbe 11 können auch Lochplatten, Gitter, Siebbleche oder ähnliche luftdurchlässige Einrichtungen vorgesehen sein. Durch die Schrägstellung der Gitterstäbe 11 ist die Kanalunterwand 19 breiter als die Kanaloberwand 12. Letztere ist über Stehbolzen 21 an Hauptträgern 2 befestigt. Die Hauptträger 2 sind üblicherweise in der Nähe der Decke einer Werkshalle montiert und tragen somit den stationären Saugkanal 22.FIG. 1 shows a suction channel 22 with a horizontal channel top wall 12 and a channel bottom wall 19 parallel thereto, which together with a channel rear wall 20 connecting the two walls form a closed box. Opposite the channel rear wall 20, a channel side wall 18 is formed by oblique bars 11, which preferably connect the channel bottom wall 19 with the passage upper wall 12 at an angle of 30 0 to 60 ° at 45 °. Instead of the grid bars 11, perforated plates, grids, screen plates or similar air-permeable devices can also be provided. Due to the inclined position of the lattice bars 11, the channel bottom wall 19 is wider than the channel top wall 12. The latter is fastened to the main beams 2 by means of stud bolts 21. The main beams 2 are usually mounted near the ceiling of a factory building and thus carry the stationary suction channel 22.

In der Nähe der Kanaloberwand 12 ist eine Lippe 7 aus Gummi oder Kautschuk durch einen Haltestreifen 9 und Schrauben 8 an dem Saugkanal 22 befestigt, und zwar vorzugsweise unter einem mit den Gitterstäben 11 fluchtenden Flansch 25 des Saugkanals 22. Die Lippe 7 erstreckt sich über die gesamte Länge des Saugkanals 22 und verschließt normalerweise mit ihrem Unterrand frei auf den Gitterstäben 11 aufliegend die Kanalseitenwand 18 des Saugkanals 22. Dadurch ist die Lippe 7 von den Gitterstäben 11 abhebbar und die Kanalseitenwand 18 kann auf diese Weise in dem Bereich geöffnet werden, in dem die Lippe 7 von den Gitterstäben 11 abgehoben ist. Hierzu dient ein Saugwagen 1 mit einem Anschlußstück 6, das in Längsrichtung des Saugkanals 22 etwa Tropfenform hat und sich allmählich sanft nach oben wölbt, so daß es bei der Bewegung des Saugwagens l entlang dem Saugkanal 22 zunächst die Lippe 7 nur geringfügig von den Gitterstäben 11 abhebt, während eine maximale Abhebung der Lippe 7 von den Gitterstäben 11 und damit eine maximale Öffnung der Kanalseitenwand 18 in der Mittelebene des Saugwagens 1 erfolgt. Zweckmäßigerweise ist die Oberseite des Anschlußstücks 6 unter einem Winkel von etwa 10° bis 30° zur Horizontalen geneigt, um die Lippe 7 nicht übermäßig hochschwenken zu müssen.In the vicinity of the channel top wall 12, a lip 7 made of rubber or rubber is fastened to the suction channel 22 by means of a retaining strip 9 and screws 8, preferably under a flange 25 of the suction channel 22 which is aligned with the bars 11. The lip 7 extends over the entire length of the suction channel 22 and normally closes with its lower edge freely on the Lattice bars 11 resting on the channel side wall 18 of the suction channel 22. As a result, the lip 7 can be lifted off the lattice bars 11 and the channel side wall 18 can be opened in this way in the area in which the lip 7 is lifted off the lattice bars 11. For this purpose, a suction vehicle 1 with a connection piece 6, which has approximately the shape of a teardrop in the longitudinal direction of the suction channel 22 and gradually curves upwards, so that when the suction vehicle 1 moves along the suction channel 22, it initially only slightly removes the lip 7 from the bars 11 lifts off, while a maximum lifting of the lip 7 from the bars 11 and thus a maximum opening of the channel side wall 18 takes place in the central plane of the suction vehicle 1. The upper side of the connecting piece 6 is expediently inclined at an angle of approximately 10 ° to 30 ° to the horizontal so that the lip 7 does not have to be swung up excessively.

Der Saugwagen 1 besitzt einen aus Querträgern 13 und Längsträgern 14 gebildeten Rahmen, der über Streben 4 und Laufräder 3 in Schienen 23 verfahrbar ist. Die Schienen 23 sind auf an sich bekannte Weise beispielsweise an den Hauptträgern 2 montiert.The suction vehicle 1 has a frame formed from cross members 13 and longitudinal members 14, which can be moved in rails 23 via struts 4 and running wheels 3. The rails 23 are mounted in a manner known per se, for example on the main supports 2.

Unter dem Anschlußstück 6 ist ein weiterer Lippenstreif en 15 in Verlängerung der Kanalunterwand 19 durch einen Haltestreifen 16 und Schrauben 17 montiert, welcher die Unterseite des Saugwagen-Anschlußstücks 6 abdichtet. Hierzu weist das Anschlußstück 6 des Schlauchwagens 1 einen sanft gekrümmten Übergangsabschnitt von seiner der Kanalseitenwand 18 benachbarten Öffnung zu dem Abgasschlauch-Anschlußbereich 26 auf.Under the connector 6, another lip strip 15 is mounted in extension of the channel bottom wall 19 by a retaining strip 16 and screws 17, which seals the underside of the suction vehicle connector 6. For this purpose, the connection piece 6 of the hose carriage 1 has a gently curved transition section from its opening adjacent to the channel side wall 18 to the exhaust hose connection area 26.

Figur 2 zeigt eine Vorderansicht in Richtung des Pfeils A auf die Vorrichtung gemäß Figur 1, wobei der aus den Querträgern 13 und den Längsträgern 14 gebildete Rahmen des Schlauchwagens 1 erkennbar ist. Außerdem erkennt man die sanfte Wölbung des Anschlußstücks 6, welche die Lippe 7 allmählich von der Kanalseitenwand 18 bis zu dem in Figur 1 dargestellten Maximum abhebt. Figur 2 ist nur eine schematische Darstellung eines Ausführungsbeispiels, in welchem Einzelheiten aus Gründen der Übersichtlichkeit weggelassen sind. Gleiche Teile wie in den Figuren 1 oder 3 sind jedoch mit gleichen Bezugszeichen versehen.FIG. 2 shows a front view in the direction of arrow A on the device according to FIG. 1, the view from FIG Cross beams 13 and the longitudinal beams 14 formed frame of the hose carriage 1 can be seen. You can also see the gentle curvature of the connector 6, which gradually lifts the lip 7 from the channel side wall 18 to the maximum shown in FIG. FIG. 2 is only a schematic illustration of an exemplary embodiment, in which details have been omitted for reasons of clarity. The same parts as in Figures 1 or 3 are provided with the same reference numerals.

Figur 3 zeigt ein anderes Ausführungsbeispiel mit einem stationären Saugkanal 22, dessen schräge Kanalseitenwand 18 in zuvor erwähnter Weise durch eine Lippe 7 aus Kautschuk oder Kunststoff aufgrund ihres Eigengewichts und des Unterdrucks verschließbar ist. Zur Halterung der Lippe 7 dienen wiederum Gitterstäbe 11; es können jedoch auch Siebplatten, Lochbleche, Gitter oder ähnliche Einrichtungen zum Halten der Lippe 7 vorgesehen sein. Das Anschlußstück 6' ist bei diesem Ausführungsbeispiel nicht um 90o nach unten abgewinkelt, sondern setzt sich etwa gerade in einen verfahrbaren Saugkanal 22' fort, welcher bis auf die Verfahrbarkeit gleich wie der stationäre Saugkanal 22 gebaut ist. Zum Verfahren des verfahrbaren Saugkanals 22' dienen an sich bekannte Streben 4', welche an ihrem oberen Ende Laufräder 3' tragen, die in Schienen 23' laufen. Die Schienen 23' sind in der zuvor erwähnten und an sich bekannten Weise an der Decke einer Werkshalle oder an Hauptträgern 2 angebracht. Die schräge Seitenwand des verfahrbaren Saugkanals 22' wird wiederum von einer Lippe 7 überdeckt, unter welche der in Figur 3 nicht erkennbare Saugwagen 1 mit seinem Anschlußstück 6 auf die in Verbindung mit Figur 1 beschriebenen Weise greift. Die Ausführungsform gemäß Figur 3 besitzt den Vorteil, daß der Schlauchwagen 1 praktisch jeden Punkt eines Rechtecks erreichen kann, welcher durch die Länge der stationären und verfahrbaren Saugkanäle 22 und 22' definiert ist.Figure 3 shows another embodiment with a stationary suction channel 22, the inclined channel side wall 18 can be closed in the aforementioned manner by a lip 7 made of rubber or plastic due to its own weight and the negative pressure. Lattice bars 11 again serve to hold the lip 7; however, sieve plates, perforated plates, grids or similar devices for holding the lip 7 can also be provided. The connecting piece 6 'is not angled in this embodiment by 90 ° downward, but is made approximately straight in a movable suction channel 22' continues, which is built up on the movability of the same as the stationary suction channel 22nd For moving the movable suction channel 22 'are known struts 4', which carry at their upper end wheels 3 'which run in rails 23'. The rails 23 'are attached to the ceiling of a workshop or to main girders 2 in the manner known and known per se. The sloping side wall of the movable suction channel 22 'is in turn covered by a lip 7, under which the suction car 1 (not recognizable in FIG. 3) engages with its connector 6 in the manner described in connection with FIG. The embodiment according to FIG. 3 has the advantage that the hose cart 1 can reach practically any point of a rectangle which is defined by the length of the stationary and movable suction channels 22 and 22 '.

Es wird darauf hingewiesen, daß in einer anderen bevorzugten Ausführungsform das Anschlußstück 6 des Saugwagens 1 in seiner Form so abgeflacht ist, daß die Lippe 7 durch den Saugwagen nur halb-ellipsenförmig angehoben wird. Gegenüber der tropfenförmigen Abhebung der Lippe 7 bedeutet die halb-ellipsenförmige Abhebung keine Querschnittsverkleinerung für ein an den Saugwagen 1 angeschlossenes Absaugrohr. Auch bei dieser Ausführungsform gleiten die Lippenwand und der Saugwagen eng aufeinander.It is pointed out that in another preferred embodiment, the connector 6 of the suction vehicle 1 is flattened in its shape in such a way that the lip 7 is only raised semi-elliptically by the suction vehicle. Compared to the drop-shaped lifting of the lip 7, the semi-elliptical lifting means no cross-sectional reduction for a suction pipe connected to the suction vehicle 1. In this embodiment, too, the lip wall and the suction car slide closely on one another.
