Abstract

Die Erfindung betrifft eine modular aufgebaute Pumpe für Kleinanwendungen die für verschiedene Einsatzzwecke genutzt werden kann. Insbesondere durch die spezielle Bauart zur medienunabhängigen Schmierung des Motors können auch viskose bzw. feststoffhaltige Medien im Dauerbetrieb gefördert werden. Durch den modularen Aufbau kann die Pumpe außerdem an den Einsatzzweck angepasst werden, was unter anderem auch eine einfache Wartung ermöglicht.The invention relates to a modular pump for small applications that can be used for various purposes. In particular, the special design for media-independent lubrication of the engine and viscous or solids-containing media can be promoted in continuous operation. Due to the modular design, the pump can also be adapted to the intended use, which among other things also enables easy maintenance.

Description

Heutige Pumpensysteme nach Stand der Technik sind universell ausgeführt nicht veränderbar oder anpassungsfähig, d h. es gibt kaum spezielle Entwicklungen für die Biogasthematik bzw, eine Anpassungsmöglichkeit der Pumpen an Zusammensetzung und Konsistenz der Biomasse im Zersetzungsprozess.Today's pump systems according to the prior art are universally executed not changeable or adaptive, d h. There are hardly any special developments for the biogas issue or an adaptation of the pumps to the composition and consistency of the biomass in the decomposition process.

Technischer Stand der Technik von SubstratpumpenTechnical state of the art of substrate pumps

• Market available laboratory and pond pumps usually run on 220 V, are without speed control and also suitable only for lightly loaded liquids
• There are no standard products that can transport solids-containing media in the area of laboratory fermentation technology - if that is expensive special solution
• Also limits in dry matter and impurities, so very maintenance-prone, high wear and short life
• Lubrication and cooling via the medium to be pumped, resulting in heavy wear of the rotor or high cleaning effort
• Danger of overheating, as the medium itself is tempered up to 55 ° C (thermophilic) and higher, no dry-running properties

Um die Anpassungsfähigkeit herzustellen wird diese Vorrichtung einer modularen Pumpe vorgeschlagen. Eine Universalpumpe soll u. a. als wichtiges Bauteil für Biogas-Modul-Systeme wie z b das BIO-ORIX eingesetzt werden, mit dem so alle Überführungsvorgänge realisiert werden können. Die Konzeption sieht ein modulares System mit standardisierten Komponenten vor, mit dem der Medientransport stufenlos und automatisch gesteuert durchgeführt werden kann.To make the adaptability, this device is proposed a modular pump. A universal pump should u. a. used as an important component for biogas module systems such as the BIO-ORIX, with which all transfer processes can be realized. The concept provides for a modular system with standardized components, with which the media transport can be steplessly and automatically controlled.

Bisheriger Technischer Stand zusammengefasst: angestrebte technische Funktionalität für die modulare UniversalpumpePrevious technical status summarized: desired technical functionality for the modular universal pump

• 24 Volt alternating current instead of 220 V as usual, direction of rotation defined
• Use of a power supply instead of a transformer to save energy
• Encapsulated cooling and lubrication of the rotor with separate medium independent of the transport medium
• Development of a new rotor with a polished ceramic axis
• Development of a new intelligent stepless pump control
• Maintenance-free operation, variable pumping attachments for liquid to pulpy substrates
