Description

Die Erfindung betrifft eine Vorrichtung zum Aufnehmen und Behandeln eines Schmutzsubstrats, insbesondere von bei der Kanalreinigung aufsaugbarem Schlamm, mit einem mit dem Schmutzsubstrat beaufschlagbaren, in einem vorzugsweise fassförmigen Behälter untergebrachten, entwässerbaren Schmutzaufnahmeraum, der im Bereich einer Seite einen bodennah angeordneten Feststoffausgang aufweist, dem ein Ausbringorgan zugeordnet ist, mittels dessen die Feststoffe aus dem Schutzaufnahmeraum heraustransportierbar sind.The invention relates to a device for recording and Treating a dirt substrate, especially when cleaning sewers absorbable sludge, with one with the dirt substrate actable, preferably in a barrel-shaped Container-housed, drainable dirt holding space, the solid outlet arranged near the ground in the area of one side has to which a discharge member is assigned, by means of the solids of which can be transported out of the protective receiving space are.

Eine Vorrichtung dieser Art, mittels welcher die im Schmutzsubstrat enthaltenen Sinkstoffe von den sie verunreinigenden Schwimmstoffen befreit und im gereinigten Zustand ausgetragen werden können, ist aus der deutschen Patentanmeldung 195 38 848 bekannt. Bei dieser bekannten Anordnung ist eine im unteren Scheitelbereich des fassförmigen Schmutzaufnahmeraums angeordnete, über die Länge des Schmutzaufnahmeraums durchgehende, dem Feststoffausgang zugeordnete Förderschnecke vorgesehen, die bei geöffnetem Feststoffausgang als Ausbringorgan und sonst als Misch- und Bewegungsorgan fungiert, durch welches die Durchmischung und Bewegung des Schmutzsubstrats unterstützt werden. Der untere Scheitelbereich des fassförmigen Schmutzaufnahmeraums ist dabei als der Förderschnecke zugeordnete Rinne ausgebildet. Die Seitenflanken dieser Rinne besitzen eine vergleichsweise flache Steigung, um bei einer vorgegebenen lichten Weite des Schmutzaufnahmeraums eine vorgegebene lichte Höhe nicht zu überschreiten. Die Folge davon ist, daß sich auf den Seitenflanken Ablagerungen bilden können, was beim Mischen einen schlechten Mischeffekt ergibt und beim Ausbringen zur Bildung von gewölbeartigen Brücken führen kann, wodurch eine vollständige Entleerung behindert wird.A device of this type, by means of which in the dirt substrate contained sediments from the contaminating them Floating substances freed and discharged in the cleaned state can be found in German patent application 195 38 848 known. In this known arrangement, one is in the lower Apex area of the barrel-shaped dirt holding space, continuous over the length of the dirt holding space screw conveyor assigned to the solids outlet provided when the solids outlet is open as a spreading device and otherwise as Mixing and movement organ acts through which the mixing and movement of the dirt substrate are supported. The lower part of the vertex of the barrel-shaped dirt holding space is here as a channel assigned to the screw conveyor educated. The side flanks of this gutter have a comparatively flat slope in order to achieve a given clear width of the Dirt receiving room does not have a predetermined clear height exceed. The consequence of this is that on the side flanks Deposits can form, which is bad when mixed Mixing effect results and when spreading to form vault-like Bridges can cause complete emptying is hindered.

Es wäre zwar denkbar, im Bereich der flachen Seitenflanken der Rinne Rütteleinrichtungen vorzusehen, um der Bildung von Ablagerungen entgegenzuwirken. Derartige Rütteleinrichtungen erweisen sich aber als sehr aufwendig und verschleißanfällig.It would be conceivable in the area of the flat side flanks Gutter vibrators should be provided to prevent the formation of deposits counteract. Such vibrators prove but proved to be very complex and prone to wear.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, daß eine hohe Betriebssicherheit und Störungsfreiheit erreicht werden.Based on this, it is therefore the task of the present one Invention, a device of the type mentioned with simple and inexpensive means to improve so that a high Operational safety and freedom from interference can be achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Ausbringorgan zumindest im Betrieb von wenigstens zwei unabhängig hiervon aktivierbaren, über die Länge des Schmutzaufnahmeraums durchgehenden, seitlichen Längsförderorganen flankiert ist, denen jeweils eine im Bereich des Bodens des Schmutzaufnahmeraums angeordnete Rinne zugeordnet ist, wobei die Rinnen im vorderen und hinteren Endbereich des Schmutzaufnahmeraums durch Querverbindungsschächte miteinander verbunden sind, und daß die Länge des Ausbringorgans zumindest der Breite des dem Feststoffausgang benachbarten Querverbindungsschachts entspricht.This object is achieved in that the Discharge device independent of at least two in operation of which can be activated over the length of the dirt holding space continuous, lateral longitudinal conveyor flanks is, each one in the area of the floor of the dirt holding space arranged gutter is assigned, the gutters in front and rear end portions of the dirt holding space are connected to one another by cross-connection shafts, and that the length of the discharge member is at least the width of the Solid exit corresponds to the adjacent cross-connection shaft.

Hiermit werden die eingangs geschilderten Nachteile des gattungsgemäßen Standes der Technik unter Beibehaltung seiner grundsätzlichen Vorteile und Wirkungsweise vermieden. Da mehrere, vorzugsweise zwei über die Länge des Schmutzaufnahmeraums durchgehende Längsförderorgane vorgesehen sind, ergeben sich in vorteilhafter Weise ohne Nachteil für das Fassungsvermögen des Schmutzaufnahmeraums vergleichsweise steile Seitenflanken der den genannten Längsförderorganen zugeordneten Rinnen, wodurch der Bildung von Ablagerungen entgegengewirkt wird, ohne daß Rütteleinrichtungen oder dergleichen benötigt würden. Zudem sind die erforderlichen Antriebsmomente geringer als bei lediglich einem mittleren Längsförderorgan. Bei Mischbetrieb können die seitlichen Längsförderorgane gegenläufig fördern. Im Bereich der endseitigen Querverbindungsschächte wird das geförderte Gut dabei von einem Längsförderorgan auf das andere übergeben, so daß sich insgesamt eine gute Durchmischung und intensive Bewegung des Inhalts des Schlammaufnahmeraums ergibt. Von der Bewegung nicht erfaßte, tote Nester und dergleichen sind nicht zu befürchten. Beim Ausbringen können die beiden seitlichen Längsförderorgane gleichgerichtet wie das Ausbringorgan fördern und als Zubringer für dieses fungieren.This eliminates the disadvantages of the generic type described above State of the art while maintaining its basic advantages and mode of action avoided. There several, preferably two, along the length of the dirt holding space continuous longitudinal conveyors are provided, result in an advantageous manner without disadvantage for the capacity the dirt holding room is comparatively steep Side flanks of the longitudinal conveying members mentioned Channels, which counteracts the formation of deposits is used without the need for vibrators or the like would. In addition, the required drive torques are lower than with only a medium longitudinal conveyor. In mixed operation can promote the lateral longitudinal conveyors in opposite directions. in the The area of the end cross-connection shafts is the funded Transfer well from one longitudinal conveyor to the other, so that overall there is good mixing and intensive Movement of the content of the sludge receiving space results. Dead nests and the like not covered by the movement not to fear. When spreading, the two side Convey longitudinal conveyors in the same direction as the spreading member and act as a feeder for this.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben. So kann zur Bildung der Querverbindungsschächte einfach im vorderen und hinteren Endbereich des Schmutzaufnahmeraums die auf der restlichen Länge zwischen den benachbarten Rinnen vorhandene Begrenzung fehlen. Diese ist zweckmäßig als dachförmiger Tunnelsteg ausgebildet. Hierdurch ergibt sich ein Aufnahmegehäuse, in welches das in axialer Richtung verschiebbare Ausbringorgan eingezogen werden kann. Hierdurch kann sichergestellt werden, daß bei Mischbetrieb jede Behinderung der Materialbewegung unterbleibt. Zum Ausbringen der gereinigten Feststoffe kann das Ausbringorgan soweit ausgefahren werden, daß es den zugeordneten Querverbindungsschacht überquert und weit in einen an den Feststoffausgang ansetzbaren Ausbringstutzen hineinreicht, so daß eine zuverlässige Ausbringung gewährleistet ist. Advantageous refinements and practical training of overriding measures are specified in the subclaims. So to form the cross-connection shafts simply in the front and rear end portions of the dirt holding space along the remaining length between the adjacent channels existing limit is missing. This is useful as a roof-shaped Tunnel bridge designed. This results in a receptacle housing in which the dispensing member is displaceable in the axial direction can be drawn in. This can ensure be that in mixed operation any hindrance to material movement omitted. For spreading the cleaned solids can be extended so far that the assigned cross-connection shaft and far into one spreading nozzle that can be attached to the solids outlet, so that a reliable application is guaranteed.

Eine weitere zweckmäßige Maßnahme kann darin bestehen, daß das Ausbringorgan und die seitlichen Längsförderorgane als wellenlose Förderschnecken ausgebildet sind. Hierdurch wird sichergestellt, daß auch vergleichsweise große Steine ohne Gefahr von Zwangskräften gefördert werden. Zudem besteht bei wellenlosen Schnecken keine Gefahr der Unterwanderung, wodurch der zu überwindende Widerstand vergleichsweise gering bleibt, so daß vergleichsweise geringe Antriebsmomente ausreichend sind.Another useful measure may be that Discharge device and the lateral longitudinal conveyors as shaftless Screw conveyors are formed. This ensures that even comparatively large stones without the risk of constraining forces be promoted. There is also a shaftless screw no danger of infiltration, making the one to be overcome Resistance remains comparatively low, so that comparatively low drive torques are sufficient.

Zweckmäßig können die die seitlichen Längsförderorgane bildenden Schnecken an ihren beiden Enden angetrieben werden, wodurch die Verwindung und damit die Beanspruchung auch bei leichter Bauweise in zulässigen Grenzen gehalten werden kann.The lateral longitudinal conveying elements can expediently form Screws are driven at both ends, causing the Distortion and thus the strain even with a light construction can be kept within permissible limits.

Eine weitere vorteilhafte Maßnahme kann darin bestehen, daß die die seitlichen Längsförderorgane bildenden Förderschnecken bei Ausbringbetrieb so angetrieben werden, daß ihre oberen Umfangshälften zur Querschnittsmitte des Schmutzaufnahmeraums hin drehen. Hierdurch ist sichergestellt, daß die äußeren Flanken der zugeordneten Rinnen zuverlässig abgeräumt werden.Another advantageous measure can be that the the lateral augers forming conveyor screws Spreading operations are driven so that their upper peripheral halves towards the cross-sectional center of the dirt holding space rotate. This ensures that the outer flanks of the assigned channels are reliably cleared.

Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben und aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung näher entnehmbar.Further advantageous refinements and practical training the overriding measures are in the rest Subclaims specified and from the example description below can be seen from the drawing.

Das den Zeichnungen zugrundeliegende Kanalreinigungsfahrzeug enthält eine auf einer Fahrzeugchassis 1 aufgenommene Behälteranordnung. Diese enthält einen mittleren, fassförmigen Behälter 2, der in einen über die ganze Fahrzeugbreite reichenden, kastenförmigen Behälter 3 teilweise eingelassen ist. Der kastenförmige Behälter 3 dient als Wassertank zur Aufnahme von Spülwasser, mittels dessen ein hier nicht näher dargestellter, in den zu reinigenden Kanal absenkbarer Räumschlauch beaufschlagbar ist.The sewer cleaning vehicle on which the drawings are based contains a container arrangement accommodated on a vehicle chassis 1. This contains a middle, barrel-shaped container 2, the box-shaped one that extends across the entire width of the vehicle Container 3 is partially embedded. The box-shaped container 3 serves as a water tank for holding rinse water, by means of one of which is not shown here, is to be cleaned Channel lowerable clearing hose can be acted upon.

Der fassförmige Behälter 2 enthält, wie die Figuren 2 und 3 zeigen, einen Schmutzaufnahmeraum 4, in den das bei der Kanalreinigung aus dem Kanal aufgesaugte Schmutz-Wasser-Gemisch eingeworfen wird, und eine durch ein Überlaufwehr 5 hiervon getrennte Rückführkammer 6, deren Funktion weiter unten näher beschrieben wird. Der als Spülwassertank fungierende Behälter 3 kann mit Wasser aus dem Schlammaufnahmeraum 4 nachgeladen werden, sofern eine mit einer entsprechenden Reinigungseinrichtung ausgestattete Nachladeeinrichtung vorgesehen ist. Die Funktionsweise und die hierfür erforderlichen Komponenten eines Kanalreinigungsfahrzeugs sind an sich bekannt und bedürfen daher im vorliegenden Zusammenhang keiner näheren Erläuterung mehr.As shown in FIGS. 2 and 3, the barrel-shaped container 2 contains a dirt receiving space 4, in which the sewer cleaning Thrown-in dirt-water mixture thrown in and a return chamber separated therefrom by an overflow weir 5 6, whose function is described in more detail below becomes. The container 3 acting as a rinsing water tank can also be used Water from the sludge receiving space 4 can be reloaded, if one is equipped with an appropriate cleaning device Reloading device is provided. How it works and the components of a sewer cleaning vehicle required for this are known per se and therefore need this No more detailed connection.

Der in den Schmutzaufnahmraum 4 eingebrachte Schmutz wird in Schwimmstoffe, bei denen es sich um Verunreinigungen wie Fäkalien und dergleichen handelt, und in Sinkstoffe, bei denen es sich um Sedimente wie Sand, Steine und dergleichen handelt, getrennt. Die Schwimmstoffe, die keine Gefahr bezüglich eines Zusetzens eines Kanals darstellen, werden in das Kanalsystem zurückgeführt. Die von den durch die Schwimmstoffe gebildeten Verunreinigungen befreiten Sedimente, die einen Kanal zusetzen würden, werden zurückgehalten. Diese können infolge ihrer Reinigung problemlos auf einer Deponie deponiert oder als Recycling-Material, beispielsweise im Straßenbau etc., verwendet werden.The dirt introduced into the dirt holding space 4 is in Floating substances that are contaminants like Faeces and the like, and in sediments where it are sediments such as sand, stones and the like, Cut. The floating substances that pose no danger to one Clogging of a channel represent in the channel system recycled. Those formed by the floating substances Contamination frees sediments that clog a channel would be held back. These can be the result of their cleaning easily deposited on a landfill or as recycling material, for example, used in road construction, etc.

Das in den Schmutzaufnahmeraum 4 eingebrachte Schmutz-Wasser-Gemisch wird zunächst entwässert. Hierzu wird das Wasser über einen Wasserauslaß 7 abgelassen. Dieses Wasser kann entweder ungeklärt in den Kanal zurückgeführt werden oder nach entsprechender Reinigung als Spülwasser Verwendung finden. Anschließend wird der zurückbleibende Schmutz mit sauberem Wasser gespült, sowie in starke Bewegung versetzt und vorzugsweise zusätzlich mit Luft beaufschlagt. Durch die Bewegung und vorzugsweise Luftbeaufschlagung ergibt sich ein Flotationseffekt. Hierbei lösen sich die Schwimmstoffe von den Sinkstoffen und schwimmen nach oben, wie in Figur 1 durch Pfeile 8 angedeutet ist. Die aufschwimmenden Schwimmstoffe bilden eine auf der Wasseroberfläche aufliegende Schwimmschicht 9. Wenn diese das Niveau der Überlaufkante des Überlaufwehrs 5 erreicht hat, wird der Behälter 2 oder hier die ganze Behälteranordnung am dem Überlaufwehr gegenüberliegenden Ende leicht angehoben, so daß die Schwimmschicht 9 über das Überlaufwehr 5 in die Rückführkammer 6 abfließt. Diese ist, wie aus den Figuren 2 und 3 entnehmbar ist, mit einem Auslaß 10 versehen, dessen Öffnung für Schwimmstoffe durchlässig ist. Über den Auslaß 10 kann der Inhalt der Rückführkammer 6 ablaufen bzw. abgedrückt und über geeignete Leitungen in den Kanal zurückgeführt werden.The dirt-water mixture introduced into the dirt-receiving space 4 is first drained. For this the water drained through a water outlet 7. This water can either unexplained can be returned to the canal or after appropriate cleaning can be used as rinsing water. Then the remaining dirt is cleaned with a clean one Rinsed water, set in motion and preferably additionally charged with air. Through the movement and preferably exposure to air results in a flotation effect. Here, the floating substances separate from the suspended matter and float upwards, as indicated by arrows 8 in FIG. 1. The floating floating substances form one on the water surface overlying floating layer 9. If this level has reached the overflow edge of the overflow weir 5, the container 2 or here the whole container arrangement on the overflow weir opposite end slightly raised so that the Floating layer 9 over the overflow weir 5 into the return chamber 6 flows off. This can be seen from FIGS. 2 and 3 is provided with an outlet 10, the opening for Floating substances are permeable. Via the outlet 10, the content the return chamber 6 run or depressed and suitable Lines are returned to the channel.

Der vorstehend beschriebene Kippvorgang zur Entfernung der Schwimmschicht 9 kann mehrmals wiederholt werden. Die Spülung mit sauberem Wasser wird solange aufrecht erhalten, bis nur noch sauberes Wasser in die Rückführkammer 6 überläuft.The tilting process described above to remove the Floating layer 9 can be repeated several times. The flush with clean water is maintained until only clean water overflows into the return chamber 6.

Zum Kippen der Behälteranordnung sind, wie Figur 1 weiter zeigt, Hubaggregate 11 vorgesehen, mittels welcher hier die gesamte Behälteranordnung anhebbar ist. Zweckmäßig können am vorderen und hinteren Ende der Behälteranordnung Hubaggregate 11 vorgesehen sein, so daß eine Schaukelbewegung erzielbar ist, durch welche die Bewegung des Inhalts des Schmutzaufnahmeraums 4 unterstützt wird. Als weitere Misch- und Bewegungseinrichtung sind im Schmutzaufnahmeraum 4 zwei über seine ganze Länge durchgehende, in nach oben offenen, bodenseitigen Rinnen 12 angeordnete Förderschnecken 13 vorgesehen. Die beiden voneinander distanzierten Rinnen 12 sind, wie aus den Figuren 2 und 3 entnehmbar ist, im Bereich des vorderen und hinteren Endes des Schmutzaufnahmeraums 4 durch Querverbindungsschächte 14 miteinander verbunden und dazwischen durch einen gemäß Figur 1 dachförmigen Tunnelsteg 15 voneinander getrennt. Dieser ist durch aus den Figuren 2 und 3 weiter ersichtliche Stirnplatten 15a verschlossen. Zur Bildung der Querverbindungsschächte 14 ist der Tunnelsteg 15 einfach endseitig um die Breite der Querverbindungsschächte verkürzt. Die seitlichen Flanken der Rinnen 12 steigen vergleichsweise steil an, wie in Figur 1 durch den Winkel α angedeutet ist. Gleichzeitig ergibt sich eine vergleichsweise große untere Breite des Behälters 2, so daß bei vorgegebener lichter Höhe ein vergleichsweise großes Fassungsvermögen erreicht wird.For tilting the container arrangement, as FIG. 1 further shows, Lifting units 11 are provided, by means of which the entire Container arrangement can be raised. Expediently can on the front and rear end of the container assembly lifting units 11 are provided be so that a rocking movement can be achieved by which is the movement of the contents of the dirt holding space 4 is supported. As another mixing and moving device are in the dirt holding space 4 two over its entire length continuous, in upwardly open, bottom-side channels 12 arranged conveyor screws 13 are provided. The two of each other are spaced channels 12, as in FIGS. 2 and 3 can be removed in the area of the front and rear ends of the Dirt receiving space 4 through cross-connection shafts 14 with each other connected and in between by one according to FIG. 1 roof-shaped tunnel web 15 separated from each other. This is through end plates 15a further shown in FIGS. 2 and 3 locked. To form the cross-connection shafts 14 is the Tunnel web 15 simply ends at the width of the cross-connection shafts shortened. The lateral flanks of the channels 12 rise comparatively steeply, as in Figure 1 by the angle α is indicated. At the same time, there is a comparatively large one lower width of the container 2, so that for a given clear height a comparatively large capacity is achieved.

Die Längsförderschnecken 13 sind als wellenlose Schnecken ausgebildet, die an ihren beiden Enden angetrieben werden, wie durch die in den Figuren 2 und 3 angedeuteten Antriebsaggregate 16 angedeutet ist. Dabei kann es sich um Hydraulikmotoren handeln. Die wellenlose Ausbildung der Längsförderschnecken 13 stellt sicher, daß Steine bis zu einem der Schneckensteigung entsprechenden Durchmesser problemlos transportierbar sind. Zudem ist sichergestellt, daß die Schnecken nicht unterwandert werden können, was den Widerstand vergrößern würde.The longitudinal conveyor screws 13 are designed as shaftless screws, which are driven at both ends, as by the indicated in Figures 2 and 3 drive units 16 is. These can be hydraulic motors. The shaftless design of the longitudinal conveyor screws 13 ensures that stones up to one corresponding to the screw pitch Diameters are easy to transport. It also ensures that the snails cannot be infiltrated what would increase the resistance.

Die Längsförderschnecken 13 sind reversierbar antreibbar. Zum Mischen und Bewegen des Inhalts des Schmutzaufnahmeraums 4 werden die beiden Längsförderschnecken 13 so angetrieben, daß sich gegenläufige Förderrichtungen ergeben. Im Bereich der Querverbindungsschächte 14 erfolgt dabei eine Übergabe des Förderguts, so daß sich eine Rundumförderung ergibt. Zum Einführen von Spülwasser und Luft in den Schmutzaufnahmeraum 4 sind von in einem oberen Behälterbereich angeordneten Sammelleitungen 17,18 abgehende, entlang der Behälterwandung nach unten geführte Stichleitungen 19,20 vorgesehen, deren Enden mit in die Rinnen 12 hineingerichteten, die Förderschnecken 13 tangential beaufschlagenden Düsen versehen oder als solche ausgebildet sein können. Durch diese Beaufschlagung der Rinnen 12 mit Spülwasser und/oder Luft ergibt sich eine besonders hochgradige Verwirbelung des Inhalts des von den Längsförderschnecken 13 bewegten Guts und damit ein besonders guter Flotationseffekt.The longitudinal screw conveyors 13 can be driven reversibly. To the Mixing and moving the contents of the dirt holding space 4 the two longitudinal screws 13 are driven so that opposite directions of funding arise. In the area of the cross-connection shafts 14 the conveyed goods are handed over, so that there is all-round funding. For introducing rinse water and air in the dirt holding space 4 are in one arranged in the upper container area manifolds 17, 18 outgoing, led down along the container wall Branch lines 19, 20 are provided, the ends of which also run into the channels 12 directed into it, tangentially affecting the screw conveyors 13 Provide nozzles or can be designed as such. By loading the channels 12 with rinsing water and / or air results in a particularly high degree of turbulence the content of the goods moved by the longitudinal screw conveyors 13 and therefore a particularly good flotation effect.

Nach Beendigung des Reinigungsvorgangs befinden sich im Schmutzaufnahmeraum 4 noch sauberes Wasser und die von den Schwimmstoffen gereinigten Sedimente. Das Wasser wird über den Auslaß 7 abgelassen. Dieses kann wie das ursprüngliche Schmutzwasser zur Nachladung des Spülwassertanks verwendet oder in den Kanal zurückgeführt werden. Die gereinigten Sedimente werden über einen am hinteren, dem Überlaufwehr 5 gegenüberliegenden Ende des Schmutzaufnahmeraums 14 vorgesehenen Feststoffauslaß 21 ausgetragen. Zur Bildung des Feststoffauslasses 21 ist die dem Überlaufwehr 5 gegenüberliegende Stirnwand des Behälters 2 mit einem bodennah angeordneten, mittigen Loch versehen, das mittels eines Schiebers 22 verschließbar ist. Der Schieber 22 ist innerhalb des Schmutzaufnahmeraums 4 angeordnet und mittels einer außerhalb hiervon angeordneten Schwenkeinrichtung 23 betätigbar. Dem den Feststoffausgang 21 bildenden Loch ist ein nach außen abstehender Anschlußstutzen 24 zugeordnet, an den zum Entleeren des Schmutzaufnahmeraums 4 ein Verlängerungsstutzen 25 ansetzbar ist, wie in Figur 3 gezeigt ist. After the cleaning process is finished Dirt storage room 4 still clean water and that of the Sediments cleaned of floating materials. The water is over the Outlet 7 drained. This can be like the original dirty water used to recharge the rinse water tank or in the Channel can be returned. The cleaned sediments are via one at the rear, opposite the overflow weir 5 End of the dirt-receiving space 14 provided solid outlet 21 carried out. To form the solids outlet 21 is the Overflow weir 5 opposite end wall of the container 2 with provided a central hole near the floor, which is connected by means of a slide 22 is closable. The slide 22 is inside the dirt receiving space 4 arranged and by means of an outside pivoting device 23 arranged therefrom can be actuated. the the hole forming the solids outlet 21 is an outwardly projecting hole Assigned connecting piece 24 to the for emptying the Dirt receiving space 4 an extension piece 25 can be attached is as shown in Figure 3.

Zur Beaufschlagung des Feststoffausgangs 21 ist eine zwischen den beiden über die ganze Länge des Schmutzaufnahmeraums 4 durchgehenden Längsförderschnecken 13 angeordnete, kürzere Ausbringschnecke 26 vorgesehen. Diese ist bei Mischbetrieb, wie Figur 2 zeigt, im dachförmigen Tunnelsteg 15 versenkt und wird zum Entleeren des Schmutzaufnahmeraums 4, wie Figur 3 zeigt, aus dem Tunnelsteg 15 soweit ausgefahren, daß sie über den ausgangsseitigen Querverbindungsschacht 14 hinweggeht und in den Feststoffausgang 21 hineinreicht. Beim der Figur 3 zugrundeliegenden Beispiel durchgreift die Ausbringschnecke 26 das den Feststoffausgang 21 bildende Loch, den hieran anschließenden Anschlußstutzen 24 sowie den hieran angesetzten Verlängerungsstutzen 25. Hierdurch wird ein zuverlässiger Vorförderer gebildet.To apply the solids outlet 21 is one between the two continuous over the entire length of the dirt holding space 4 Longitudinal screw conveyors 13 arranged, shorter discharge screw 26 provided. This is in mixed operation, as Figure 2 shows, sunk in the roof-shaped tunnel web 15 and becomes Emptying the dirt holding space 4, as shown in FIG. 3 the tunnel web 15 extended so far that it over the exit Cross-connection shaft 14 goes away and into the solids outlet 21 reaches into it. In the basis of Figure 3 For example, the spreading screw 26 penetrates the solids outlet 21 forming hole, the connecting piece connected to it 24 and the extension piece 25 attached to it. This forms a reliable pre-conveyor.

Zur Aufnahme der Ausbringschnecke 26 kann im vom Tunnelsteg 15 begrenzten Raum ein Rohr 27 angeordnet sein, das an eine entsprechende Öffnung der ausgangsseitigen Stirnplatte 15a des Tunnelstegs 15 anschließt. Die Ausbringschnecke 26 ist zweckmäßig ebenfalls als wellenlose Schnecke ausgebildet, in die der Antrieb am inneren Ende eingeleitet wird. Hierzu ist das innere Ende der Ausbringschnecke 26 über eine in das Aufnahmerohr 27 eingreifende Stange 28, deren äußere Länge etwa der axialen Verschiebbarkeit der Ausbringschnecke 26 entspricht, mit einem Antriebsmotor 29 verbunden, bei dem es sich ebenfalls um einen Hydraulikmotor handeln kann. Dieser ist auf einer Konsole 30 aufgenommen, die an einem hier als Hydraulikzylinder ausgebildeten Verschiebeaggregat 31 befestigt ist. Mit Hilfe des Verschiebeaggregats kann die Ausbringschnecke 26 in axialer Richtung in das Aufnahmerohr 27 eingerückt bzw. aus diesem ausgefahren werden.To accommodate the spreading screw 26 can in the tunnel web 15 limited space, a tube 27 may be arranged, which is connected to a corresponding Opening of the end plate 15a of the output Tunnel web 15 connects. The spreading screw 26 is useful also designed as a shaftless screw into which the Drive is initiated at the inner end. For this is the inner End of the spreading screw 26 into the receiving tube 27 engaging rod 28, the outer length of which is approximately axially displaceable corresponds to the spreading screw 26, with a Drive motor 29 connected, which is also a Hydraulic motor can act. This is on a console 30 added, which is designed here as a hydraulic cylinder Shift unit 31 is attached. With the help of the sliding unit can the spreading screw 26 in the axial direction in the receiving tube 27 indented or extended from this become.

Beim Ausbringen der gereinigten Sedimente aus dem Schmutzaufnahmeraum 4 fördern beide seitlichen Längsförderschnecken 13 in Richtung zum Feststoffausgang 21 hin. Die Längsförderschnecken 13 sind dabei so ausgebildet, daß ihre obere Umfangshälfte bei dieser Betriebsweise von der äußeren Rinnenflanke zur Behälterquerschnittsmitte hin dreht, wodurch die äußere Rinnenflanke zuverlässig abgeräumt wird. Die beiden Längsförderschnecken 13 fungieren dabei als Zubringer für die ausgefahrene, gleichläufig fördernde Ausbringschnecke 26.When removing the cleaned sediments from the dirt holding area 4 convey both lateral longitudinal screw conveyors 13 towards the solids outlet 21. The longitudinal conveyor screws 13 are designed so that their upper circumferential half in this mode of operation from the outer flank to The middle of the cross-section of the container turns, creating the outer flank flank is reliably cleared. The two longitudinal screw conveyors 13 act as feeders for the extended, co-feeding screw 26.

Die Erfindung ist nicht auf die dargestellte Ausführung beschränkt. So wäre es beispielsweise möglich, das Ausbringorgan zum Ausbringen der Feststoffe über den Feststoffausgang von außen in den Schmutzaufnahmeraum hineinzufahren.The invention is not limited to the embodiment shown. For example, it would be possible to use the dispensing member for dispensing the solids via the solids outlet from the outside into the Drive in the dirt holding space.
