Abstract

Polyethylene, polypropylene or a copolymer in the form of sheets which is cut to the required size of the collecting tank, bent into a round shape on a roll bending machine, and the ends of the sheets butt welded. Covers, bottoms and other parts are cut out with templates and welded on the inside and outside with an extruder. Method allows very simple mfr. of plastic collecting tanks in the most varied sizes, and prevents deposition of dirt or grease on the tank surfaces.

Description

Durch ein derartiges Verfahren können Sammelbehälter aus Kunststoff für eine Abwasserhebeanlage auf einfachste Weise in unterschiedlichsten Größen hergestellt werden. Such a method can make collecting containers made of plastic for a sewage lifting plant produced in the simplest possible way in a wide variety of sizes will.

Patentanspruch: Verfahren zum Herstellen von Sammelbehältern aus Kunststoff für eine Abwasserhebeanlage, d a -durch gekennzeichnet, daß als Kunststoff Polyäthylen, Polypropylen oder deren Mischpolymerisate verwendet werden, die auf einer Walzenrundbiegemaschine kalt rundgewalzt und dann stumpf verschweißt werden. Claim: Method for producing collecting containers from Plastic for a sewage lifting plant, d a -characterized in that as plastic Polyethylene, polypropylene or their copolymers are used on the a roller bending machine can be cold rolled and then butt welded. Die Erfindung betrifft ein Verfahren zum Herstellen von Sammelbehältern aus Kunststoff für eine Abwasserhebeanlage. The invention relates to a method for producing collecting containers Made of plastic for a sewage lifting plant. Abwasserhebeanlagen werden in Ein- und Mehrfamilienhäusern sowie Hotels, Schulen, Krankenhäusern u. dgl. eingebaut, um die Abwässer in ein höherliegendes Abwasserkanalsystem zu pumpen. Sewage lifting systems are used in single and multi-family houses as well Hotels, schools, hospitals and the like built in to transfer the wastewater to a higher level Pump sewer system. Derartige Abwasserhebeanlagen bestehen aus einem Sammelbehälter, Pumpen, die geeignet sind, Abwasser und Fäkalien zu fordern, einer wasserstandsabhängigen Niveauregulierung und einer Schalt- und Steuerungseinrichtung. Such sewage lifting systems consist of a collecting tank, Pumps that are suitable for handling wastewater and faeces are dependent on the water level 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 Duromeren in der Sanitärtechnik thermoplastische Kunststoffe zu verwenden. It is already known, the gas, odor and water-tight collecting container instead of steel from impact-resistant, glass fiber reinforced polyester resin. On the other hand, z. B. from the magazine "Heating, Ventilation and Building Technology", 1969, S. 277 to 281 known, instead of thermosets in sanitary engineering thermoplastic Use plastics. 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 made when using duromer Plastics in the hand lay-up process, hand spray process, compression process or winding and centrifugal processes. This has so far been the case in particular during manufacture small quantities or very large molded parts applied. The production of tubular bodies made of thermoplastic such as polyethylene, Polypropylene or their copolymers have hitherto been carried out by extruding the tubular body or by laterally leading up an endless belt over a core and closing of the pipe by a weld or the like. With subsequent Cutting to length. The effort required for an expensive tool is only worthwhile for the production of large series. However, this is in the case of collecting tanks for wastewater lifting plants, which can have different dimensions are not given. 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 through which a collecting tank for a waste water lifting system made of a plastic, on which no deposits of dirt and grease can accumulate, with the simplest means can be produced. 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 Polyethylene, polypropylene or their copolymers are used on the a roller bending machine can be cold rolled 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 collecting tanks in a wastewater lifting plant. PE and PP is commercially available, among other things, in plate form. These panels just need still cut to the desired size of the collecting container, on one The roller bending machine is rounded and the plate ends are then butt welded together will. Lid, base and other parts are cut out according to templates and welded inside and outside with an extruder.
