Abstract

A suction-type street cleansing vehicle comprises a suction pipe 3 for conveying refuse to a refuse holder 2 having an inclined deflecting plate 11 for guiding the refuse after it leaves the suction pipe, the top of the refuse holder downstream of the deflecting plate being connected to a radial fan 9, and there being means for reducing pressure in the air stream at or adjacent the free edge of the plate 11 comprising a curved lip 12 whereby the air is urged to flow upwardly and the air and refuse are separated. The fan 9 supplies a blow pipe 5. <IMAGE>

Description

Die Erfindung betrifft ein selbstaufnehmendes Straßenkehrfahrzeug mit einer den Kehricht von einer Kehrfläche in einen Kehrichtsammelbehälter befördernden Saugleitung und einer den Kehricht nach dem Austreten aus der Saugleitung schräg zum Boden des Kehrichtsammelbehälters ablenkenden Prallplatte, hinter welcher die Oberseite des Kehrichtsammelbehälters an ein Radialgebläse angeschlossen ist.The invention relates to a self-picking up street sweeper with a suction line that conveys the rubbish from a sweeping area into a garbage collection bin and a baffle plate that deflects the garbage after exiting the suction line at an angle to the bottom of the garbage collection bin, behind which the top of the garbage collection bin is connected to a radial fan.

Bei den bisher bekannten Ausführungen dieser Art endet die Prallplatte abrupt in einer freien Kante. Nach der der Erfindung zugrundeliegenden Erkenntnis wird dabei die Luft wie in einem freien Strahl geradlinig nach schräg unten bis an den aus abgeschiedenem Kehricht und Sprühwasser bestehenden Sumpf mitgerissen. Dadurch kann schmutziges Wasser wieder mit hochgerissen werden, was zur Verschmutzung der austretenden Luft und Wirbelbildung führt. Solche unerwünschten Folgen können verstärkt auftreten, wenn zusätzlich Wasser in die Saugleitung eingespritzt wird, um mittels Agglomeration die Schmutzpartikel des Kehrichts besser abzuscheiden.In the previously known designs of this type, the baffle plate ends abruptly in a free edge. According to the knowledge on which the invention is based, the air is entrained as in a free jet straight downwards to the sump consisting of separated waste and spray water. This means that dirty water can be pulled up again, which leads to pollution of the escaping air and eddy formation. Such undesirable consequences can increase if there is additional water in the suction line is injected in order to better separate the dirt particles of the refuse by means of agglomeration.

Um diese Nachteile zu beseitigen, liegt der Erfindung die Aufgabe zugrunde, die Abscheidung der Schmutzteilchen des Kehrichts aus ihrer Transportluft zu verbessern und hinter der freien Kante der Prallplatte eine ruhige Luftaustrittsströmung zu gewinnen.In order to eliminate these disadvantages, the object of the invention is to improve the separation of the dirt particles of the refuse from their transport air and to obtain a calm air outlet flow behind the free edge of the baffle plate.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die freie Kante der Prallplatte nach oben so gekrümmt ist, daß die mit Kehricht beaufschlagte Luft ähnlich wie an einer Tragfläche abgelenkt wird, ohne daß der Kehricht selbst mitgerissen wird.According to the invention, this object is achieved in that the free edge of the baffle plate is curved upward in such a way that the air charged with waste is deflected similarly to a wing without the waste itself being carried away.

Bei der Erfindung entsteht durch die Krümmung am Ende der Prallplatte in der Strömung ein Unterdruck, der den Luftstrom ab- bzw. umlenkt, nicht aber das Weiterfliegen der Schmutzteilchen aufgrund ihrer Trägheit in der alten Richtung beeinträchtigt. Der Kehricht wird dabei also in den Sumpf geleitet, der Luftstrom dagegen vor Erreichen der Sumpfoberfläche zum größten Teil nach oben an den Anschluß der Oberseite des Kehrichtsammelbehälters an den Saugstutzen eines Radialgebläses abgelenkt. Eine weitgehend verbesserte Trennung der Schmutzteilchen von der Luft ist die Folge, ebenso auch eine ruhige Austrittsströmung der Luft; ein Hochreißen von Schmutzwasser wird vermieden. Die Nutzung aerodynamischer Regeln für die Gestaltung der freien Kante der Prallplatte im Rahmen der Erfindung läßt mit denkbar geringem technischen Aufwand überraschend große Vorteile für den Gegenstand der Erfindung gewinnen.In the invention, the curvature at the end of the baffle plate creates a negative pressure in the flow, which deflects or deflects the air flow, but does not impair the further flying of the dirt particles due to their inertia in the old direction. The garbage is thus directed into the sump, whereas the air flow is largely deflected upwards before reaching the sump surface at the connection of the top of the garbage collection container to the suction port of a radial fan. The result is a largely improved separation of the dirt particles from the air, as well as a quiet outlet flow of the air; wiping up dirty water is avoided. The use of aero dynamic rules for the design of the free edge of the baffle plate within the scope of the invention can surprisingly achieve great advantages for the subject matter of the invention with the least possible technical outlay.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt.An embodiment of the invention is shown schematically in the drawing.

Das komplett dargestellte Straßenkehrfahrzeug besteht im wesentlichen aus dem Fahrgestell mit Fahrerhaus lund einem Kehrichtsammelbehälter 2. Durch eine Saugleitung 3 wird der von einem Kehrbesen 4 aufgerissene Kehricht (schwarze Pfeile) mit Unterstützung einer Blasleitung 5 von der Straße weggesaugt und an einer Öffnung 10 der Saugleitung 3 in den Kehrichtsammelbehälter 2 geschleudert. Dabei wird der Luftstrom mit dem Kehricht an einer an der Oberseite des Kehrichtsammelbehälters 2 angebrachten schrägen Prallplatte 11, die bei 13 gerundet ist, umgelenkt. Der Kehricht wird dabei nach schräg unten abgetrieben und der vom Kehricht befreite Luftstrom entweicht über ein den Kehrichtsammelbehälter 2 abdeckendes Sieb 8 zu einem der Blasleitung 5 vorgeschalteten Radialgebläse 9.The street sweeper shown in its entirety consists essentially of the chassis with driver's cab and a rubbish collecting bin 2. The rubbish (black arrows) torn open by a broom 4 is sucked away from the street by a sweeper 4 and supported by a blower duct 5 and at an opening 10 of the suction line 3 thrown into the rubbish bin 2. The air flow with the rubbish is deflected at an inclined baffle plate 11 which is attached to the top of the rubbish collecting container 2 and is rounded at 13. The rubbish is driven obliquely downwards and the air stream freed of the rubbish escapes via a sieve 8 covering the rubbish collecting container 2 to a radial fan 9 upstream of the blow line 5.

Damit die Trennung von Luft und Kehricht möglichst optimal wird, ist die freie Kante 12 der Prallplatte 11 nach oben so gekrümmt, daß die mit Kehricht beaufschlagte Luft ähnlich wie an einer Tragfläche etwa in Richtung der dargestellten drei Pfeile abgelenkt wird, ohne daß der Kehricht selbst mitgerissen wird.So that the separation of air and rubbish is as optimal as possible, the free edge 12 of the baffle plate 11 is curved upwards in such a way that the air charged with rubbish is similar to a wing approximately in the direction of the three shown Arrows is deflected without the garbage itself being carried away.
