Description

Vorrichtung zLim Aufbau einer flüssigkeitsdurch- lässigen Bodenbelagsplatte, Schachtabdeckung od.dgl. Device zL in the construction of a liquid-permeable floor covering plate, manhole cover or the like.
Die vorliegende Erfindung betrifft eine Vorrichtung zum Aufbau einer flüssigkeitsdurchlässigen Bodenbelagsplatte, Schachtabdeckung od.dgl.The present invention relates to a device for constructing a liquid-permeable floor covering plate, manhole cover or the like.
Derartige Vorrichtungen sind in Form von Kanaldeckeln, perforierten Bodenplatten, sogar speziellen Filterplatten bekannt. Beispielsweise ist aus der EP 0 651 835 des gleichen Autors ein mehrschichtiges Filterelement bekannt, bei welchem die freien Durchströmquerschnitte jeder Filterschicht von Schicht zu Schicht in Durchströmrichtung zunehmen. Bei den bekannten Filterelementen werden die Filterschichten aus porösen, fest gebundenen Materialien wie poröser Beton oder Asphaltschichten gebildet, die aneinandergrenzen.Such devices are known in the form of manhole covers, perforated base plates, even special filter plates. For example, EP 0 651 835 by the same author discloses a multilayer filter element in which the free flow cross sections of each filter layer increase from layer to layer in the flow direction. In the known filter elements, the filter layers are formed from porous, firmly bonded materials such as porous concrete or asphalt layers that adjoin one another.
Die Erfindung setzt sich zum Ziel, die bekannten Filterelemente so weiterzubilden, daß sie überaus einfach zu fertigen, befestigbar und frostunempfindlich sind und eine verbesserte selbstreinigende Wirkung besitzen. Dieses Ziel wird mit einer Vorrichtung erreicht, die sich auszeichnet durch zwei voneinander beabstandete, über eine Umfangswand miteinander verbundene, perforierte Platten, die zwischeneinander einen Aufnahmeraum bilden, wobei die lichte Weite der Perforationen der oberen Platte im wesentlichen kleiner als jene der unteren Platte ist.The aim of the invention is to further develop the known filter elements in such a way that they are extremely easy to manufacture, attachable and frost-resistant and have an improved self-cleaning effect. This goal is achieved with a device which is characterized by two spaced-apart, perforated plates which are connected to one another by a peripheral wall and form a receiving space between them, the clear width of the perforations of the upper plate being substantially smaller than that of the lower plate.
Das erfindungsgemäße Filterelement kann in Form einer runden, eckigen oder beliebig geformten Kassette, Patrone oder Platte gefertigt und beispielsweise in den Einlaß eines Abwasser- oder Abluftschachtes eingesetzt oder einfach als flüssig- keitsdurchlässige Bodenflächenbefestigung auf einen drainagierenden Untergrund aufgelegt werden. Die an sich bekannte Abfolge schichtweise zunehmender Durchströmquerschnitte gewährleistet prinzipiell, daß in der zu filternden bzw. abzufordernden Flüssigkeit enthaltene Feststoffe nur bis zu einer bestimmten Korngröße in die erste Platte eindringen können. Korngrößen, die gleich oder kleiner als die Perforationen der oberen Platte sind, werden in der Filtervorrichtung nicht zurückgehalten, sondern treten durch die untere Platte aus. Der zwischen den beiden Platten vorgesehene Aufnahmeraum ermöglicht eine freie Bewegung der eingetretenen Feststoffe, so daß diese durch das nachtretende Abflußwasser umspült und solange neuorientiert werden, bis sie jedenfalls durch die untere Platte austreten. Der zwischen den Platten liegende Aufnahmeraum verbessert daher entscheidend den Austrag allfällig eingeschwemmter Feststoffe aus dem Filterelement.The filter element according to the invention can be manufactured in the form of a round, angular or arbitrarily shaped cassette, cartridge or plate and, for example, inserted into the inlet of a waste water or exhaust air shaft or simply as a liquid permeable floor surface fastenings are placed on a draining surface. The known sequence of increasing flow cross sections increases in principle that solids contained in the liquid to be filtered or to be removed can only penetrate into the first plate up to a certain grain size. Grain sizes that are equal to or smaller than the perforations of the upper plate are not retained in the filter device, but emerge through the lower plate. The receiving space provided between the two plates allows the solids that have entered to move freely, so that they flow around the downstream drainage water and are reoriented until they emerge through the lower plate. The receiving space between the plates therefore decisively improves the discharge of any washed-in solids from the filter element.
Darüber hinaus kann der Aufnahmeraum in besonders vorteilhafter Weise mit einer Filterschicht aus Schotter, Kies, Betongranulat od.dgl. gefüllt werden, wobei die lichte Weite der zwischen den Granulatkörnern der Filterschicht verbleibenden Durchströmquerschnitte zwischen jener der oberen und jener der unteren Platte liegt. Mit anderen Worten kann die erfindungsgemäße Filtervorrichtung sowohl ohne als auch mit Befüllung nutzbringend angewendet werden.In addition, the receiving space can in a particularly advantageous manner with a filter layer made of crushed stone, gravel, concrete granules or the like. be filled, the clear width of the flow cross-sections remaining between the granules of the filter layer between that of the upper and that of the lower plate. In other words, the filter device according to the invention can be used both without and with filling.
Anstelle einer Filterschicht kann alternativ ein Filterkörper in den Aufnahmeraum eingelegt werden, bevorzugt aus Metall- oder Kunststoffwaben oder perforierten Noppenplatten, wobei die lichte Weite seiner Durchströmquerschnitte zwischen jener der oberen und jener der unteren Platte liegt. Die Filterschicht bzw. der Filterkörper kann an sich während der Fertigung der Vorrichtung bereits eingefüllt und bleibend in der Vorrichtung aufgenommen werden. Besonders vorteilhaft ist es jedoch, wenn gemäß einer bevorzugten Ausgestaltung der Erfindung in der Umfangswand eine verschließbare Öffnung zur Befüllung des Aufnahmeraumes vorgesehen ist. Alternativ kann bevorzugt zumindest eine der Platten an der Umfangswand in eine Offenstellung verschwenkbar gelagert sein. Eine weitere bevorzugte Variante besteht darin, daß zumindest eine der Platten über eine lösbare Steckverbindung mit der Umfangswand verbunden ist.Instead of a filter layer, a filter body can alternatively be inserted into the receiving space, preferably made of metal or plastic honeycombs or perforated knobbed panels, the clear width of its flow cross-sections being between that of the upper and that of the lower panel. The filter layer or the filter body per se can already be filled in during the manufacture of the device and permanently absorbed in the device. However, it is particularly advantageous if, according to a preferred embodiment of the invention, a closable opening for filling the receiving space is provided in the peripheral wall. Alternatively, at least one of the plates can preferably be pivotably mounted on the peripheral wall into an open position. Another preferred variant is that at least one of the plates is connected to the peripheral wall via a detachable plug connection.
Diese Ausführungsformen mit einem Aufnahmeraum, der geöffnet werden kann, sind auch von Vorteil, wenn das Filterelement ohne Befüllung verwendet wird, da sie den Zugang zum Aufnahmeraum zur Inspektion ermöglichen.These embodiments with a receiving space that can be opened are also advantageous if the filter element is used without filling, since they allow access to the receiving space for inspection.
Eine besonders verschleißfeste, robuste und dabei einfach zu fertigende Ausführungsform der Erfindung besteht darin, daß die Platten und die Umfangswand aus Metallblech gefertigt sind. Alternativ ist insbesondere auch eine Fertigung aus verschleißfesten Kunststoffplatten bzw. -elementen vorstellbar.A particularly wear-resistant, robust and easy to manufacture embodiment of the invention consists in that the plates and the peripheral wall are made of sheet metal. Alternatively, production from wear-resistant plastic plates or elements is also conceivable.
Die Erfindung wird nachstehend an Hand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. In den Zeichnungen zeigen die Fig. 1 bis 4 eine erste Ausführungsform der erfindungsgemäßen Vorrichtung in der Draufsicht, im Querschnitt, in der Untersicht und in der rechten Seitenansicht, und die Fig. 5 und 6 Querschnitte durch zwei alternative Ausführungsformen der Erfindung.The invention is explained in more detail below on the basis of exemplary embodiments illustrated in the drawings. 1 to 4 show a first embodiment of the device according to the invention in plan view, in cross section, in bottom view and in right side view, and FIGS. 5 and 6 show cross sections through two alternative embodiments of the invention.
Die in den Fig. 1 bis 4 dargestellte Filtervorrichtung besteht im wesentlichen aus zwei quadratischen, perforierten Platten 1, 2, die über eine rahmenförmig umlaufende Umfangswand 3 an ihrem Umfang miteinander verbunden sind und zwischeneinander einen Aufnahmeraum 4 bilden. Die lichte Weite der Perforationen 5 der oberen Platte 1 ist kleiner als die lichte Weite der Perforationen 6 der unteren Platte 2. Die Platten 1, 2 können aus beliebigen Materialien gefertigt sein, bevorzugt sind sie jedoch aus Lochblechen gebildet. Die Umfangswand 3 kann ebenfalls aus Metallblech gefertigt werden und mit den Platten 1, 2 verschweißt, vernietet, verschraubt verklebt, vergossen od.dgl. werden. Die Platten 1, 2 und die Umfangswand 3 können auch aus verschleißfesten Kunststoffplatten bzw. -ele enten gefertigt werden.The filter device shown in FIGS. 1 to 4 consists essentially of two square, perforated Plates 1, 2, which are connected to one another at their periphery via a peripheral circumferential wall 3 and form a receiving space 4 between them. The clear width of the perforations 5 of the upper plate 1 is smaller than the clear width of the perforations 6 of the lower plate 2. The plates 1, 2 can be made from any materials, but they are preferably formed from perforated sheets. The peripheral wall 3 can also be made of sheet metal and welded to the plates 1, 2, riveted, screwed, glued, cast or the like. become. The plates 1, 2 and the peripheral wall 3 can also be made of wear-resistant plastic plates or ducks.
Der Aufnahmeraum 4 kann frei bleiben oder, wie in Fig. 2 dargestellt, mit einer Filterschicht 7 aus granulärem Material wie Schotter, Kies, Betongranulat od.dgl. befüllt werden. Auch die alternative Verwendung eines Filterkörpers, z.B. aus porösem Beton, porösen Kunststoffen, einem Gitter, Metall- oder Kunststoffwaben, perforierten Noppenplatten, Vliesen od.dgl. kann in Betracht gezogen werden. Ein solcher Filterkörper kann vorgefertigt in den Aufnahmeraum 4 eingelegt oder eingeschoben werden. Wesentlich ist jedenfalls, daß die lichte Weite der zwischen den Granulatkörnern, Poren, Maschen usw. der Filterschicht 7 bzw. des Filterkörpers verbleibenden Durchströmquerschnitte zwischen jener der oberen Platte 1 und jener der unteren Platte 2 liegt, oder überhaupt größer als jene der oberen Platte 5 ist.The receiving space 4 can remain free or, as shown in Fig. 2, with a filter layer 7 made of granular material such as gravel, gravel, granular concrete or the like. be filled. The alternative use of a filter body, e.g. made of porous concrete, porous plastics, a grid, metal or plastic honeycomb, perforated studded panels, nonwovens or the like. can be considered. Such a filter body can be prefabricated inserted or inserted into the receiving space 4. In any case, it is essential that the clear width of the flow cross-sections remaining between the granules, pores, meshes etc. of the filter layer 7 or the filter body lies between that of the upper plate 1 and that of the lower plate 2, or is at all greater than that of the upper plate 5 is.
Die Filterschicht 7 bzw. der Filterkörper kann während der Fertigung in den Aufnahmeraum 4 eingebracht werden. Besser ist es jedoch, eine Öffnungsmöglichkeit vorzusehen, über welche die Filterschicht bzw. der Filterkörper nachträglich eingebracht bzw. bei Bedarf inspiziert, gereinigt oder ausgetauscht werden kann. Bei der Ausführungsform der Fig. 1 bis 4 ist zu diesem Zweck in der Umfangswand 3 eine Öffnung 8 ausgespart, welche hier die gesamte rechte Seite des Filterelementes einnimmt und mit Hilfe eines Schiebers 9, der in entsprechenden Führungen 10, 11 gleitet, verschlossen werden kann.The filter layer 7 or the filter body can be introduced into the receiving space 4 during manufacture. However, it is better to provide an opening option through which the Filter layer or the filter body can be introduced later or inspected, cleaned or replaced if necessary. In the embodiment of FIGS. 1 to 4, an opening 8 is recessed in the peripheral wall 3 for this purpose, which here occupies the entire right side of the filter element and can be closed with the aid of a slide 9 which slides in corresponding guides 10, 11 .
Die Fig. 5 und 6 zeigen alternative Ausführungsformen, um eine Öffnungsmöglichkeit für den Aufnahmeraum 4 zu schaffen. In Fig. 5 ist die obere Platte 1 mit Hilfe eines Gelenkes 12 an einer Seite der Umfangswand 3 in eine (nicht gezeigte) Offenstellung verschwenkbar gelagert. In Fig. 6 ist die obere Platte 1 über eine Steckverbindung 13 mit der Umfangswand 3 lösbar verbunden. Selbstverständlich kann die Öffnung auch an der Unterseite der Filtervorrichtung vorgesehen werden.5 and 6 show alternative embodiments in order to create an opening possibility for the receiving space 4. In Fig. 5, the upper plate 1 is pivotally supported by a hinge 12 on one side of the peripheral wall 3 in an open position (not shown). In Fig. 6, the upper plate 1 is detachably connected to the peripheral wall 3 via a plug connection 13. Of course, the opening can also be provided on the underside of the filter device.
Zur Verbesserung der Tragfähigkeit der Filtervorrichtung können zusätzlich Stützrippen 14 an der Unterseite der Platte 1 (Fig. 6) bzw. der Platte 2 (Fig. 5) vorgesehen werden.To improve the load-bearing capacity of the filter device, additional support ribs 14 can be provided on the underside of plate 1 (FIG. 6) or plate 2 (FIG. 5).
Die Erfindung ist selbstverständlich nicht auf die dargestellten Ausführungsbeispiele beschränkt, sondern kann in Form und Material im Rahmen der angeschlossenen Ansprüche beliebig abgewandelt werden. Beispielsweise kann die Umfangsform der Platten 1, 2 rund, oval, polygonal oder unregelmäßig sein, und ebenso die Form der Perforationen 5, 6. The invention is of course not limited to the exemplary embodiments shown, but can be modified as desired in terms of shape and material within the scope of the attached claims. For example, the peripheral shape of the plates 1, 2 can be round, oval, polygonal or irregular, as can the shape of the perforations 5, 6.
