Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Sammelbehältern aus Kunststoff für eine Abwasserhebeanlage. The invention relates to a method for producing collecting tanks made of plastic for a sewage lifting plant.

Abwasserhebeanlagen werden in Ein- und Mehrfamilienhäusern sowie Hotels, Schulen, Krankenhäusern u. dgl. eingebaut, um die Abwasser in ein höherliegendes Abwasserkanalsystem zu pumpen.Wastewater lifting plants are used in single and multi-family houses as well as hotels, schools and hospitals and the like installed in order to pump the sewage into a sewer system at a higher level.

Derartige Abwasserhebeanlage!) bestehen aus einem Sammelbehälter, Pumpen, die geeignet sind. Abwasser und Fäkalien zu fördern, einer wasserstandsabhängigen Niveauregulierung und einer Schalt- und Steuerungseinrichtung. Such sewage lifting system!) Consist of a collecting tank, pumps that are suitable. sewage and to convey feces, a water level-dependent level control and a switching and control device.

Es ist bereits bekannt, den gas-, geruch- und wasserdichten Sammelbehälter anstatt aus Stahl aus schlagfestem, glasfaserverstärktem Polyesterharz herzustellen. Andererseits ist z. B. aus der Zeitschrift »Heizung-Lüftung-Haustechnik«, 1969, S. 277 bis 281 bekannt, anstatt Dümmeren in der Sanitärtechnik thermoplastische Kunststoffe zu verwenden.It is already known to use the gas-, odor- and waterproof collecting container instead of made of steel to produce impact-resistant, glass fiber reinforced polyester resin. On the other hand, z. B. from the magazine "Heating-ventilation-building technology", 1969, pp. 277 to 281 known, instead of more stupid in the sanitary technology to use thermoplastics.

Die Herstellung der Sammelbehälter kann bei der Verwendung duromerer Kunststoffe im Handauflegeverfahren, Handspritzverfahren, Preßverfahren oder Wickel- und Schleuderverfahren erfolgen. Dieses wird bisher insbesondere bei der Herstellung geringer Stückzahlen oder sehr groß dimensionierter Formteile angewendet. Die Herstellung von rohrförmigen Körpern aus thermoplastischem Kunststoff, wie z. B. Polyäthylen, Polypropylen oder deren Mischpolymerisate, erfolgte bisher durch Extrudieren des rohrförmigen Körpers bzw. durch seitliches Hochführen eines endlosen Bandes über einen Kern und Schließen des Rohres durch eine Schweißnaht od. dgl. mit nachträglichem Ablängen. Der dafür notwendige Aufwand für ein teueres Werkzeug lohnt sich nur bei der Fertigung großer Serien. Dieses ist aber bei Sammelbehältern für Abwasserhebeanlagen, die unterschiedliche Abmessungen aufweisen können, nicht gegeben.The production of the collecting container can be done at the Use of duromer plastics in the hand lay-up process, Hand spraying processes, pressing processes or winding and centrifugal processes are carried out. This will so far especially in the production of small quantities or very large molded parts applied. The production of tubular bodies made of thermoplastic material, such as. B. Polyethylene, polypropylene or their copolymers were previously made by extruding the tubular Body or by laterally raising an endless belt over a core and closing the Pipe through a weld seam or the like with subsequent cutting to length. The effort required for a expensive tools are only worthwhile when producing large series. But this is in the case of collecting containers for Wastewater lifting plants that can have different dimensions are not available.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren aufzuzeigen, durch welches ein Sammelbehälter für eine Abwasserhebeanlage aus einem Kunststoff, an dem sich keine Ablagerungen von Schmutz- und Fettstoffen ansetzen können, mit einfachsten Mitteln hergestellt werden kann.The invention is therefore based on the object of showing a method by which a collecting container for a waste water lifting system made of a plastic, on which there are no deposits of dirt and fatty substances, can be produced with the simplest means.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Kunststoff Polyäthylen, Polypropylen oder deren Mischpolymerisate verwendet werden, die auf einer Walzenrundbiegemaschine kalt rundgewalzt und dann stumpf verschweißt werden.According to the invention, this object is achieved in that the plastic used is polyethylene, polypropylene or whose copolymers are used, which are cold-rolled on a roller bending machine and then butt welded.

Polyäthylen, Polypropylen oder deren Mischpolymerisate haben die gewünschten Eigenschaften für Sammelbehälter einer Abwasserhebeanlage. PE und PP liegt handelsüblich unter anderem in Plattenform vor. Diese Platten brauchen nur noch auf die gewünschte Größe des Sammelbehälters zurechtgeschnitten, auf einer Walzenrundbiegemaschine rundgebogen und die Plattenenden anschließend stumpf zusammengeschweißt werden. Deckel-, Boden- und andere Teile werden nach Schablonen ausgeschnitten und mit einem Extruder innen und außen geschweißt.Polyethylene, polypropylene or their copolymers have the desired properties for Collection tank of a sewage lifting plant. PE and PP are commonly available in sheet form, among other things. These plates only need to be cut to the desired size of the collecting container a round roll bending machine and then butt welded the plate ends together will. Lid, base and other parts are cut out according to templates and with a Extruder welded inside and out.

Durch ein derartiges Verfahren können Sammelbehälter aus Kunsts'.off für eine Abwasserhebeanlage auf einfachste We>se in unterschiedlichsten Größen hergestellt werden.Such a method allows collecting tanks made of plastic for a sewage lifting plant simplest ways can be produced in a wide variety of sizes.
