Abstract

A vehicle having a tank (2) which is connected to a water-jet pump used as a sludge pump and from whose compartment accommodating the sludge (21) a filter (14) separates off a rinsing water compartment (22) from which a low-pressure pump (4) which supplies the motive water for the water-jet pump (25) is fed via a fine filter, the novel feature being that the water-jet pump (25) is preceded on its suction side by a collector (29) for any relatively large solid parts (30) which may be produced, thus reducing the free cross-section of the water-jet pump (25). <IMAGE>

Description

Die Erfindung betrifft einen Schlammsaugewagen mit einem an eine als Schlammpumpe verwendete Wasserstrahlpumpe angeschlossenen Behälter, von dessen den Schlamm aufnehmenden Raumteil ein Filter einen Spülwasserraumteil separiert, aus welchem über einen Feinfilter eine das Treibwasser für die Wasserstrahlpumpe liefernde Niederdruckpumpe gespeist wird.The invention relates to a sludge suction vehicle with a container connected to a water jet pump used as a sludge pump, from the space part of which receives the sludge a filter separates a rinse water space part, from which a low pressure pump supplying the motive water for the water jet pump is fed via a fine filter.

Vorteilhaft an einem Fahrzeug mit der beschriebenen Ausrüstung (DE-PS 26 48 851) ist, daß sein Wasserbedarf weitgehend aus dem von ihm selbst mitführbaren Wasservorrat gedeckt werden kann, der ständig erneuert wird, so daß Hydranten zum Frischwassertanken höchst selten angesteuert und damit Arbeitsunterbrechungen in Kauf genommen werden müssen. Die Verwendung einer Wasserstrahlpumpe zum Hochsaugen des Schlamms hat gegenüber einer Evakuierung des gesamten Behälters den Vorzug, daß der Behälter nicht vakuumdicht gehalten werden muß. Für eingedickte Schlämme, die zum Aufsaugen erst mit Wasser verflüssigt werden müssen und wie sie z.B. in Sinkkästen vorkommen, oder andere trockene Sauggüter bringt der Einsatz dieser Fahrzeugausrüstung ebenfalls besondere Vorteile.An advantage of a vehicle with the equipment described (DE-PS 26 48 851) is that its water requirements can largely be met from the water supply it can carry itself, which is constantly renewed, so that hydrants for fresh water refueling are rarely activated and work breaks in Purchase must be made. The use of a water jet pump for sucking up the sludge has the advantage over evacuation of the entire container that the container does not have to be kept vacuum-tight. For thickened sludges that first have to be liquefied with water and how they e.g. occur in gullies, or other dry suction goods, the use of this vehicle equipment also brings special advantages.

In dem anfallenden Schlamm können - zumal bei dem angedeuteten weiten Einsatzbereich - auch größere Festteile, z.B. leere Büchsen oder Dosen, die als Wegwerfbehältnisse von Getränken gedient haben, wenn auch seltener, vorkommen. Ihre Abförderung würde die Auslegung der Wasserstrahlpumpe mit einem entsprechend großen freien Querschnitt erfordern. Nach der der Erfindung zugrundeliegenden Erkenntnis würde das die Installierung-einer Pumpenleistung erfordern, die zu der benötigten, auf die gesamte Betriebseinheit bezogenen Durchschnittsleistung in einem großen Mißverhältnis stehen würde. Außerdem würde damit eine Wassermenge angefördert werden, zu deren Aufnahme der Behälter zu klein wäre.Larger solid parts, e.g. in the indicated wide range of use, can also be found in the resulting sludge. empty cans or cans that have served as disposable beverage containers, albeit more rarely. Your removal would require the design of the water jet pump with a correspondingly large free cross section. According to the knowledge on which the invention is based, this would require the installation of a pump output which would be in a large disproportion to the required average output relating to the entire operating unit. It would also deliver a quantity of water that the container would be too small to hold.

Der Erfindung liegt deshalb die Aufgabe zugrunde, durch eine Ausrüstung des Fahrzeugs bei Verwendung einer Wasserstrahlpumpe die Möglichkeit zum Hochsaugen auch größerer Festteile mit der Installierung einer Pumpenleistung zu vereinigen, welche der benötigten Durchschnittsleistung etwa entspricht.The invention is therefore based on the object, by equipping the vehicle when using a water jet pump, to combine the possibility of sucking up even larger solid parts with the installation of a pump output which corresponds approximately to the required average output.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß der Wasserstrahlpumpe auf ihrer Saugseite ein Abscheider für möglicherweise anfallende größere Festteile vorgeordnet ist, bezüglich welcher der freie Querschnitt der Wasserstrahlpumpe vermindert ist. Diese größeren Festteile werden infolgedessen mit hochgefördert, brauchen aber nicht den freien Querschnitt der Wasserstrahlpumpe zu passieren, sondern werden vorher abgefangen.According to the invention, this object is achieved in that the water jet pump is preceded on its suction side by a separator for possibly occurring larger solid parts, with respect to which the free cross section of the water jet pump is reduced. As a result, these larger solid parts are conveyed upwards, but do not need to pass through the free cross-section of the water jet pump, but are intercepted beforehand.

Der Abscheider ist in den Schlammbehälterraumteil entleerbar, z.B. über eine Verschlußklappe, was zweckmäßig in den Saugpausen durch elektro-pneumatische Betätigung immer automatisch erfolgt, damit sich in dem Abscheider kein unkontrollierter Widerstand aufbaut.The separator can be emptied into the sludge compartment part, e.g. via a closing flap, which is always done automatically in the suction pauses by electro-pneumatic actuation, so that no uncontrolled resistance builds up in the separator.

Der Wasserstrahlpumpe kann auf ihrer Mischstromseite ein Ventil nachgeordnet sein, durch dessen Schließen der Treibwasserstrom durch den Abscheider umgeleitet werden kann, womit dessen Reinigung jederzeit möglich ist, bzw. auch eine völlige Entleerung des Behälters vom Spülwasser, z.B. für die Heim- oder für die Rückfahrt zur Deponie.A valve can be arranged downstream of the water jet pump on its mixed flow side, by closing which the motive water flow can be diverted through the separator, thus cleaning it is possible at any time, or even a complete emptying of the container from the rinsing water, e.g. for the home or for the return trip to the landfill.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung an einem zum Reinigen von Abwasserkanälen eingerichteten Schlammsaugewagen dargestellt. Es zeigt

  • Fig. 1 ein Fahrzeug in Seitenansicht
  • Fig. 2 in der Hinteransicht
  • Fig. 3 schematisch die Funktionsweise und
  • Fig. 4 eine Einzelheit aus der Hinteransicht.
An embodiment of the invention is shown in the drawing on a mud suction vehicle set up for cleaning sewers. It shows
  • Fig. 1 shows a vehicle in side view
  • Fig. 2 in the rear view
  • Fig. 3 shows schematically the operation and
  • Fig. 4 shows a detail from the rear view.

Auf einem Fahrgestell 1 sind ein Behälter 2, der zum Entleeren nach hinten kippbar ist, eine Hochdruck- und eine Niederdruckpumpe 3 bzw. 4, eine Kippvorrichtung 5 und Waschdüsen 6 montiert. Im Kanalschacht 7 sind ein Hochdruckwasserschlauch 8 mit einer Düse 9 und ein Saugschlauch 10 zu sehen. Am Behälterdeckel 11 sind eine Haspel 12 für den Hochdruckwasserschlauch 8 und eine Haspel 13 für den Saugschlauch 10 befestigt. Im Behälter 2 sind eine Filtertrennwand 14, Schwallwände 15 und eine weitere Trennwand 16 zur Bildung einer kleinen Vorratskammer 17 für Frischwasser eingebaut. Dieses Frischwasser steht besonders nach dem Entleeren des Behälters vom Schlamm für Reinigungsarbeiten am Fahrzeug zur Verfugung. Bei Beginn der Arbeitsfahrt wird die Vorratskammer 17 über die Einfüllvorrichtung 18 gefüllt, damit zugleich auch der Behälter 2 über die Verbindungsleitung 19 aus dem Vorratsbehälter 17. Die Hochdruckpumpe 3 entnimmt aus dem durch die Filtertrennwand 14 separierten Raumteil des Behälters 2 das Spülwasser und fördert es über den Hochdruckwasserschlauch 8 zur Düse 9.A container 2, which can be tilted backwards for emptying, a high-pressure and a low-pressure pump 3 or 4, a tilting device 5 and washing nozzles 6 are mounted on a chassis 1. A high-pressure water hose 8 with a nozzle 9 and a suction hose 10 can be seen in the manhole 7. A reel 12 for the high-pressure water hose 8 and a reel 13 for the suction hose 10 are fastened to the container lid 11. A filter partition 14, baffles 15 and a further partition 16 to form a small storage chamber 17 for fresh water are installed in the container 2. This fresh water is available for cleaning work on the vehicle, especially after emptying the container from the sludge. At the start of the work trip, the storage chamber 17 is filled via the filling device 18, so that the container 2 is also removed from the storage container 17 via the connecting line 19 the high pressure water hose 8 to the nozzle 9.

Für das Fördern des Schlamms ist die Niederdruckwasserpumpe 4 vorgesehen, mit der eine Wasserstrahlpumpe 25 betrieben wird. Das Wasser hierzu kann aus dem Behälter 2 oder Vorratskammer 17 entnommen werden. An der Wasserstrahlpumpe 25. ist der Saugschlauch 10 angeschlossen, der über die Haspel 13 gelagert und bewegt wird.The low-pressure water pump 4, with which a water jet pump 25 is operated, is provided for conveying the sludge. The water for this can be removed from the container 2 or storage chamber 17. The suction hose 10 is connected to the water jet pump 25 and is stored and moved via the reel 13.

Im Behälter 2 lagern sich die festen Bestandteile 21 am Boden ab, und das Schlammwasser 22 steht wieder zum Spülen zur Verfügung. Durch dieses Prinzip wird es je nach dem Wasserlauf im Kanal nicht mehr oder nur sehr selten notwendig sein, den SpHlwasservorrat am Hydranten zu ergänzen. Über einen weiteren Hochdruckschlauch 23 kann auch eine Spritzpistole 24 mit Hochdruckwasser zur Reinigung von Flächen oder Wänden versorgt werden.In the container 2, the solid components 21 are deposited on the bottom, and the sludge water 22 is again available for rinsing. Due to this principle, depending on the water flow in the canal, it will no longer be necessary, or only very rarely, to supplement the rinse water supply at the hydrant. A spray gun 24 can also be supplied with high-pressure water for cleaning surfaces or walls via a further high-pressure hose 23.

Durch die Niederdruckwasserpumpe 4 können für Reinigungsarbeiten auch noch andere Spritzvorrichtungen, z.B. die Waschdüsen 6 oder ein Strahlrohr 26 versorgt werden. Wenn es erforderlich ist, kann das Sauggut über ein Düsensystem 27 aufgelockert werden. Für dieses Düsensystem 27 wird vom Wasser für die Wasserstrahlpumpe 25 ein Teil abgezweigt. Die Verbraucher der Niederdruckwasserpumpe 4 können auch durch die Hochdruckwasserpumpe 3 versorgt werden. 28 ist ein Sicherheits- und Schaltventil.The low-pressure water pump 4 can also be used for other spraying devices for cleaning work, e.g. the washing nozzles 6 or a jet pipe 26 are supplied. If necessary, the suction material can be loosened via a nozzle system 27. For this nozzle system 27, part of the water for the water jet pump 25 is branched off. The consumers of the low pressure water pump 4 can also be supplied by the high pressure water pump 3. 28 is a safety and switching valve.

Wie aus Fig. 3 und 4 erkennbar ist, ist der Wasserstrahlpumpe 25 auf ihrer Saugseite ein Abscheider 29 für möglicherweise seltener anfallende größere Festteile 30 vorgeordnet, bezüglich welcher der freie Querschnitt der Wasserstrahlpumpe 25 vermindert ist. Der Abscheider 29 ist in den Schlammbehälterraumteil 2 entleerbar über eine Verschlußklappe 31, die von einem Pneumatikzylinder 32 mit Kolbenstange 33 über Kniehebel 34 bedienbar ist. Das erfolgt zweckmäßigerweise automatisch in den Saugpausen. Ein Ventil 35 auf der Mischstromseite der Wasserstrahlpumpe 25 läßt durch Schließen den Treibwasserstrom durch den-Abschneider 29 umleiten.As can be seen from FIGS. 3 and 4, the water jet pump 25 is preceded on its suction side by a separator 29 for larger solid parts 30 which may occur less frequently, with respect to which the free cross section of the water jet pump 25 is reduced. The separator 29 can be emptied into the sludge container space part 2 via a closure flap 31 which can be operated by a pneumatic cylinder 32 with a piston rod 33 via a toggle lever 34. This is conveniently done automatically in the suction breaks. A valve 35 on the mixed flow side of the water jet pump 25 allows the motive water flow to be diverted through the cutter 29 by closing.
