Beschreibung description
Die Erfindung betrifft einen Fermenter in liegender bzw. horizontaler Anordnung nach dem Oberbegriff des Anspruchs 1. Die Erfindung findet insbesondere bei Grossraumfermentern Anwendung, vorzugsweise in Form von Fermentern zur Vergärung von Bioabfall, wie z.B. biogene, organische Küchen-und Gartenabfälle. The invention relates to a fermenter in a horizontal or horizontal arrangement according to the preamble of claim 1. The invention is used in particular in large-scale fermenters, preferably in the form of fermenters for fermenting bio-waste, such as biogenic, organic kitchen and garden waste.
Es ist bekannt, Bioabfall in horizontal gelagerten Fermentern, wie in EP-A 476 217 beschrieben, zu vergären. Zur Förderung der anaeroben Vorgänge im Bioabfall wird dieser ständig mittels eines Rührwerkes durchmischt. Das Rührwerk wird über eine Welle angetrieben. It is known to ferment biowaste in horizontally stored fermenters, as described in EP-A 476 217. To promote the anaerobic processes in the bio-waste, this is constantly mixed by means of an agitator. The agitator is driven by a shaft.
Ein hohes Aufkommen an zu vergärendem Bioabfall rechtfertigt den Bau entsprechend gross-volumiger Fermenter. Da aus Verfahrensgründen der Durchmesser eines Fermenters nur bedingt ver-grössert werden kann, führt dies zu einer erheblichen Zunahme der Länge des Fermenters und der Rührwerkswelle. Aus technischen und wirtschaftlichen Gründen ist es notwendig, derartig lange Wellen durch Mittellager abzustützen. A high volume of bio-waste to be fermented justifies the construction of large-volume fermenters. Since the diameter of a fermenter can only be increased to a limited extent for process reasons, this leads to a considerable increase in the length of the fermenter and of the agitator shaft. For technical and economic reasons, it is necessary to support such long shafts with central bearings.
Der Erfindung liegt nun die Aufgabe zugrunde, einen Fermenter der gattungsgemässen Art so weiter zu entwickeln, dass solche Mittellager im Betriebszustand des Fermenters zugänglich und ggf. auch auswechselbar sind. The invention is based on the object of further developing a fermenter of the generic type in such a way that such central bearings are accessible in the operating state of the fermenter and can also be replaced if necessary.
Die Lösung dieser Aufgabe erfolgt mittels der kennzeichnenden Merkmale des Anspruchs 1. Vorteilhafte Weiterbildungen der erfindungsgemässen Lösung sind Gegenstand der abhängigen Ansprüche. Die Erfindung gestattet es, ein solches Mittellager während des Anlagenbetriebs zu inspizieren und ggf. ohne Eingriff in den Fermenter selbst zu wechseln. Letzteres kann innerhalb weniger Stunden erfolgen. Der Wechsel eines von aussen unzugänglichen Lagers würde einen Anlagenstillstand von 1-2 Monaten bewirken. This object is achieved by means of the characterizing features of claim 1. Advantageous further developments of the solution according to the invention are the subject of the dependent claims. The invention makes it possible to inspect such a central bearing during plant operation and, if necessary, to change it without intervention in the fermenter itself. The latter can be done within a few hours. Changing a warehouse that is inaccessible from outside would result in a plant downtime of 1-2 months.
Die Erfindung ist nachfolgend an Hand einer Zeichnung näher beschrieben. In der Zeichnung zeigen die The invention is described below with reference to a drawing. In the drawing they show

Fig. 2: ein Schnittbild des Inspektionsschachtes mit den Lagerstellen des Mittellagers Fig. 2: a sectional view of the inspection shaft with the bearing points of the central bearing
Fig. 3: eine Schnittdarstellung eines Mittellagers 3 shows a sectional view of a central bearing
In der Zeichnung sind die erfindungswesentlichen Teile eines Fermenters 8, mit einer Länge von 25 m und einem Durchmesser von 4 m, dargestellt. Die Welle 1 eines nicht dargestellten Rührwerkes im Fermenter 8 ist auf Grund ihrer Länge geteilt ausgeführt. Die Teilung erfolgt bevorzugt mittig zur Längsrichtung des Fermenters 8. Beide Teile der Welle 1 sind jeweils zweifach gelagert. Die Lagerstellen 2, 3 der Mittellager 2' und 3' sind in einer Schachtkonstruktion achsfluchtend angeordnet. Der Innenraum des Fermenters 8 ist von diesem, senkrecht zur Längsachse der Welle 1 angeordnetem Lagerschacht 4 luft- und wasserdicht getrennt. Im Lagerschacht 4 kann sich eine Person normal bewegen und dabei die Mittellager 2' und 3' kontrollieren oder ggf. auch auswechseln. Zum Letztgenannten wird zunächst mittels einer Schraube 5 die Welle 1 in ihrer Lage fixiert. Nach dem Lösen der Schrauben 6 und Befestigen der Abziehvorrichtung 7 am Mittellager 2', 3' kann das Mittellager 2', 3' abgezogen werden. In umgekehrter Reihenfolge erfolgt die Montage eines neuen Lagers. In the drawing, the parts of a fermenter 8 essential to the invention are shown, with a length of 25 m and a diameter of 4 m. The shaft 1 of an agitator (not shown) in the fermenter 8 is divided because of its length. The division preferably takes place in the center of the longitudinal direction of the fermenter 8. Both parts of the shaft 1 are each mounted twice. The bearing points 2, 3 of the central bearings 2 'and 3' are arranged in a shaft construction in alignment with the axis. The interior of the fermenter 8 is airtight and watertight separated from this, arranged vertically to the longitudinal axis of the shaft 1 storage shaft 4. A person can move normally in the storage shaft 4, checking or, if necessary, replacing the central bearings 2 'and 3'. Finally, the shaft 1 is first fixed in its position by means of a screw 5. After loosening the screws 6 and attaching the pulling device 7 to the central bearing 2 ', 3', the central bearing 2 ', 3' can be removed. The assembly of a new bearing takes place in reverse order.
