Abstract

A new apparatus for extracting water from product or sewage sludge on the spot is provided. It is characterized by a frame matched to the dimensions of a low loader and having lifting supports which can be pivoted in and out and which have multi-step vertical adjustability. Filter presses of substantially higher capacity than those on known apparatuses employing a semitrailer can be used.

Description

Die Erfindung betrifft eine Einrichtung zum Entwässern von Produkt- oder Abwasserschlämmen vor Ort. Diese Einrichtung besteht aus einer handeisüblichen Plattenfilterpresse und einem diese aufnehmenden Rahmen, der mit verstellbaren Hubstutzen ausgerüstet ist.The invention relates to a device for dewatering product or sewage sludge on site. This device consists of a conventional plate filter press and a frame that accommodates it, which is equipped with adjustable lifting nozzles.

Plattenfilterpressen, die transportabel sind und zum Entwässern von Schlamm am Anfallort des Schlamms aufgestellt werden können, sind bekannt (Prospekt ACHEMA 1985 der Fa. SI Schlammpress-Technik und Industriereinigung GmbH & Co. KG/Dormagen). Dort ist auf einen handelsüblichen Sattelauflieger eine Plattenfilterpresse montiert. Der Sattelauflieger besitzt an den vier Ecken ausfahrbare Kubstützen, die den Sattelauflieger mit der Filterpresse in eine solche Höhe bringen, daß der Filterkuchen z.B. in einem darunter aufgestellten Transport-Müllcontainer aufgefangen und abtransportiert werden kann.Plate filter presses that are portable and can be set up to dewater sludge at the sludge point of origin are known (brochure ACHEMA 1985 from SI Schlammpress-Technik und Industrierreinigung GmbH & Co. KG / Dormagen). There a plate filter press is mounted on a standard semi-trailer. The semi-trailer has extendable cubic supports at the four corners bring the semi-trailer with the filter press to such a height that the filter cake can be collected and transported away, for example, in a transport waste container set up underneath.

Aus der DE-A-34 11 375 ist eine Entwässerungsanlage für Schlamme bekannt, deren Anlagenteile in Normcontainern untergebracht sind, die vor Ort zu der Entwässerungsanlage zusammengefügt werden. Normcontainer haben weder eine Hubvorrichtung zum Kochstellen der Plattenfilterpresse noch wird der durch ihre Außenabmessungen vorgesehene Raum optimal genutzt.From DE-A-34 11 375 a dewatering system for sludge is known, the system parts of which are accommodated in standard containers which are assembled on site to form the dewatering system. Standard containers neither have a lifting device for cooking the plate filter press nor the space provided by their external dimensions is used optimally.

Es bestand daher die Aufgabe, eine Transporteinrichtung für eine vor Ort einzusetzende Plattenfilterpresse zu entwickeln, die eine wesentlich höhere Kapazität aufweist. Hierzu ist es nötig, die Transportbreite und -höhe eines Schwertransporters möglichst weitgehend auszunutzen und den Rahmen, auf den die Plattenfilterpresse gestellt ist, so zu modifizieren, daß er aus eigener Kraft aufgestellt, angehoben und wieder abgebaut werden kann. Die Lösung dieser Aufgabe besteht darin, daß der Rahmen für den Transport durch einen Tieflader ausgebildet und mit hydraulisch mehrstufig ausfahrbaren Hubstützen versehen ist, die in ihrer eingezogenen Stellung in den Umriß des Rahmens eingeschwenkt werden können. Der Rahmen ist also nicht selbst Transportelement, sondern besitzt die Abmessungen und die Festigkeit für den Transport durch einen qängigen Tieflader. Da ein Tieflader eine wesentlich größere Bauhöhe der Filterpresse zuläßt als ein Sattelauflieger, kann eine kapazitätsgrößere Presse eingesetzt werden. Außerdem ist dann über dem Rahmen mehr Platz für die insgesamt dann auch höheren Hubstützen, die zudem noch seitlich schwenkbar sind und somit beim Transport nicht über die Kontur des Rahmens nach außen vorstehen. Im Betrieb wird die Pressenbedienung durch die dann nach außen geschwenkten Hubstützen nicht behindert. Der Raum unter der Filterpresse ist besser zugänglich für Filterkuchenbehälter.The task was therefore to develop a transport device for a plate filter press to be used on site, which has a significantly higher capacity. For this purpose, it is necessary to use the transport width and height of a heavy transporter as far as possible and to modify the frame on which the plate filter press is placed so that it can be set up, lifted and dismantled under its own power. The solution to this problem is that the frame is designed for transport by a low loader and is provided with hydraulically extendable jacks which can be swiveled into the outline of the frame in their retracted position. The frame is not itself a transport element, but has the dimensions and strength for transport by a large flatbed trailer. Since a low loader allows a much larger height of the filter press than a semi-trailer, a larger capacity press can be used. In addition, there is then more space above the frame for the then also higher lifting supports, which can also be pivoted laterally and thus do not protrude beyond the contour of the frame during transport. During operation, the press operation is not hindered by the lifting supports which are then pivoted outwards. The space under the filter press is more accessible for filter cake containers.

Aus der EU-A1-0 025 768 ist ein einen geschlossenen Aufsatz aufweisendes Transportsystem mit abkuppelbaren Fahrgestellen bekannt. Der Auflieger besitzt Hubstützen, mit denen der Aufsatz zwecks Herausziehen der Fahrgestelle angehoben und danach abgesetzt wird. Dieses Transportsystem weist nicht die Vorteile des vorbeschriebenen neuen Rahmens auf.From EU-A1-0 025 768 a closed system transport system with uncouplable chassis is known. The semi-trailer has lifting supports with which the attachment is lifted to pull out the chassis and then lowered. This transport system does not have the advantages of the new frame described above.

Die Schwenkeinrichtung für jede Hubstütze besteht vorzugsweise aus einem an einer Rahmenecke verankerten, vertikal nach oben abstehenden Lagerzapfen und einer über diesem Lagerzapfen schwenkbaren Lagerbuchse, die die Gleitführung für die Hubstütze an einem sehr kurzen Auslegerarm trägt. Hubstütze und Gleitführung haben dabei vorzugsweise einen rechteckigen oder quadratischen Querschnitt, so daß sich Drehsicherungen erübrigen. Die Lagerbuchse läßt sich vorzugsweise in den beiden Stellungen des Auslegerarms durch einen Querstift arretieren.The pivoting device for each lifting support preferably consists of a vertically upwardly projecting bearing pin anchored to a frame corner and a bearing bush which can be pivoted above this bearing pin and which carries the sliding guide for the lifting support on a very short extension arm. The lift support and sliding guide preferably have a rectangular or square cross section, so that there is no need for rotation locks. The bearing bush can preferably be locked in the two positions of the cantilever arm by a cross pin.

Weitere wesentliche Merkmale der neuen Entwässerungseinrichtung gehen aus den Unteransprüchen und der nachfolgenden Beschreibung einer bevorzugten Ausführungsform hervor. Es zeigen im einzelnen:

Wie insbesondere Fig. 3 zeigt, besteht der Rahmen 1 aus zwei Querhäuptern 2 und zwei Längsprofilen 3, die an den Ecken durch Knoten 4 verbunden sind. Die Plattenfilterpresse 5 sitzt mit ihren Ständern 6 nur auf den Querhäuptern 2 auf und wird dort durch Steckzapfen 7 positionsgenau gegen Verschieben gesichert. Die auf den Längsprofilen 3 vorgesehenen Dreieckshalter 8 dienen dazu, die Zugstangen 9 der Filterpresse 5 im unbelasteten Zustand am Durchhängen zu hindern.As shown in FIG. 3 in particular, the frame 1 consists of two crossheads 2 and two longitudinal profiles 3, which are connected at the corners by nodes 4. The plate filter press 5 sits with its stands 6 only on the crossheads 2 and is secured there by pin 7 against displacement. The triangular holders 8 provided on the longitudinal profiles 3 serve to prevent the tie rods 9 of the filter press 5 from sagging in the unloaded state.

Aus Fig. 4 und 5 ist die Ausbildung der Hubstützen-Schwenklager 10 zu ersehen. Als Lagerzapfen 11 dienen auf den Rahmenknoten 4 verankerte, vertikal nach oben abstehende Säulenstummel, die in entsprechend verrippten Konsolen 12 eingeschweißt sind. Ober sie ist eine mit enger Passung versehene Lagerbuchse 13 gesteckt, die einen kurzen Auslegerarm 14 mit Doppel-T-Profil trägt. Am freien äußeren Ende des Auslegerarms 14 ist die Gleitführung 15 für die aus Quadratrohr bestehende Hubstütze 16 befestigt. Beide Lagerelemente können durch Querstifte 17, 18 in der ausgeschwenkten Stellung der Gleitführung 15 arretiert werden. Die Lagerbuchse 13 besitzt auf ihrer Rückseite eine Zuglasche 19, die im ausgeschwenkten Zustand der Hubstütze 16 mit der Oberseite des Pressenständers 6 verschraubt werden kann. Auf diese Weise wird das Schenklager im aufgeständerten Zustand des Rahmens mit der Filterpresse zu einem druck- und zugsteifen Gebilde verbunden. Die Auflagerkräfte werden ohne Erzeugung von Biege- und Schermomenten in die Presse übergeleitet.4 and 5, the design of the lifting support pivot bearing 10 can be seen. Serving as bearing pins 11 on the frame knot 4, vertically projecting column stubs, which are welded into correspondingly ribbed brackets 12. Above it is fitted a bearing bush 13 with a close fit, which carries a short extension arm 14 with a double-T profile. At the free outer end of the cantilever arm 14, the slide guide 15 is attached for the lifting support 16 consisting of a square tube. Both bearing elements can be locked by transverse pins 17, 18 in the pivoted-out position of the slide guide 15. The Bearing bush 13 has on its rear side a pull tab 19 which can be screwed to the top of the press stand 6 when the lifting support 16 is pivoted out. In this way, the leg bearing is connected to the filter press in the raised state of the frame to form a structure that is resistant to pressure and tension. The support forces are transferred to the press without generating bending and shear moments.

Die Einrichtung zur Hubverstellung der Hubstütze enthält einen doppelt wirkenden Hydraulikkolben 20, eine Anlenkgabel 21 und einen mit der Hubstütze 16 verriegelbaren (Querstift 22) Gleitschuh 23, in dessen seitlicher Gabel 24 der Kopf der Kolbenstange 25 angelenkt ist. Der Gleitschuh 23 ist unten verschlossen und besitzt dort eine Steckbuchse 26 für den mit einem entsprechenden Steckzapfen versehenen Ständerfuß 27, der eine breite Fußplatte zum Aufsitzen auf einem vor Ort erstellten Fundament 28 aufweist. Die Steckbuchse 26 ist so dimensioniert, daß sie über den auf dem Längsprofil 3 des Rahmens sitzenden Steckzapfen 37 paßt und somit die Hubstützen im eingeschwenkten Zustand, in dem sie mit dem Lagerzapfen 11 nicht verstiftet werden kann, sicher arretiert.The device for the stroke adjustment of the lifting support contains a double-acting hydraulic piston 20, a coupling fork 21 and a lockable with the lifting support 16 (cross pin 22) slide shoe 23, in the side fork 24 of which the head of the piston rod 25 is articulated. The slide shoe 23 is closed at the bottom and there has a socket 26 for the stand base 27 provided with a corresponding plug pin, which has a wide base plate for sitting on a foundation 28 created on site. The socket 26 is dimensioned so that it fits over the spigot 37 sitting on the longitudinal profile 3 of the frame and thus securely locks the lifting supports in the pivoted-in state in which they cannot be pinned to the bearing pin 11.

Fig. 1 zeigt den Rahmen mit der Filterpresse 5 so, wie er vom Tieflader abgehoben ist. Die Presse nimmt beim Transport nur den strichpunktiert angedeuteten Raum 30 in Anspruch. Die Hubstützen 16 ragen über diese Kontur nicht hinaus. Nach dem Ausrichten des Rahmens über den Fundamenten werden die Hubstützen zunächst hydraulisch aus den Steckzapfen 7 gehoben und dann nach außen geschwenkt. In dieser Stellung erfolgt die Arretierung der Lagerbuchsen 13 durch die Querstifte 17. Nun werden alle vier Hubstützen 16 synchron ausgefahren und kurz vor Erreichen der Fundamente die Ständerfüße 27 untergesetzt. Jetzt werden die Jetzt werden die Geleitschuhe 23 der Kolbenstangenköpfe von den Hubstützen 16 durch Ziehen der Querstifte 23 gelöst und anschließend durch Einfahren der Kolbenstangen 25 nach oben gefahren. Dort werden sie mit den Hubstützen 16 in den Querlöchern 31 verstiftet. Danach können durch Beaufschlagen der Hydraulikzylinder in Hubrichtung die Querverstiftungen 18 der Gleitführungen 15 gelöst und die Hubstützen 16 bis in die oberste Stellung ausgefahren werden, in der sie erneut mit der Gleitführung verstiftet werden (Querbohrung 32). Der Tieflader kann herausgefahren und die Presse angeschlossen und in Betrieb genommen werden.Fig. 1 shows the frame with the filter press 5 as it is lifted from the low loader. The press only takes up the space 30 indicated by dash-dotted lines during transport. The lifting supports 16 do not protrude beyond this contour. After aligning the frame over the foundations, the jacks are first hydraulically lifted out of the plug pins 7 and then pivoted outwards. In this position, the bearing bushes 13 are locked by the cross pins 17. Now all four lifting supports 16 are extended synchronously and the stand feet 27 are placed shortly before the foundations are reached. Now they are Now the guide shoes 23 of the piston rod heads are released from the lifting supports 16 by pulling the cross pins 23 and then moved upwards by retracting the piston rods 25. There they are pinned in the cross holes 31 with the lifting supports 16. Thereafter, the cross pins 18 of the slide guides 15 can be loosened and the lifting supports 16 can be extended to the uppermost position in which they are pinned again with the slide guide (cross hole 32) by acting on the hydraulic cylinders in the stroke direction. The low loader can be pulled out and the press connected and put into operation.

Der Abbau erfolgt in umgekehrter Reihenfolge.The dismantling takes place in reverse order.
