  • the biogas produced in the anaerobic fermentation of the biomass is used to provide energy in the form of thermal and / or electrical energy, while the fermented biomass or the biogenic waste can be used as a fertilizer, inter alia in agriculture.
  • Such fermenters have a transverse agitator, which enables a graft-flow type operation of the fermenter with corresponding transport of the biomass, completely crossing the fermenter.
  • the agitator here has a stirrer shaft, which is arranged in the longitudinal direction in a horizontal fermenter.

  • the assembly time for the attachment of the stirring arms is reduced accordingly, causing the Fermenter is faster to build.
  • the blade shapes and / or the sizes of the blades must be adjusted. If the reduced number of blades must move the same amount of biomass, the forces acting on the blades, agitator arms and agitator shaft inevitably increase, which must be taken into account. Inevitably, more emphasis must be placed on the connection between the stirring arms and the agitator shaft. It would have to be used stirring arms with greater wall thickness and stabilized construction. So that these are also sufficiently firmly connected to the agitator shaft, the skilled person would attach even more welds and control accordingly.

Due to the extremely fast and reliable fixation of the stirring arms 2 on site on the agitator shaft 1, the total assembly time of the fermenter is greatly reduced.

Abstract

L'invention concerne un arbre agitateur (1) d'un fermentateur d'une installation de biogaz avec un volet d'agitateur (12) disposé sur une paroi ondulée (10), sur lequel au moins un bras d'agitation (2), comprenant un segment de fixation du bras d'agitation (20) et un support d'aubes (21), peut être relié par la fixation de deux plaques de fixation de bras d'agitation (200) du bras d'agitation (2) sur les volets d'agitateur (12). L'invention vise à proposer un procédé qui permette un montage simplifié et accéléré d'un arbre agitateur et l'intégration dans un fermentateur sur site, afin de réaliser des économies considérables lors du montage d'un fermentateur. A cet effet, des trous de fixation sont pratiqués dans les volets d'agitateur (12), et des trous débouchants sont pratiqués dans les plaques de fixation du bras d'agitation (200) de telle manière qu'une multiplicité de boulons sertis (3) peuvent être placés de manière à traverser complètement les trous de fixation et les trous débouchants et y être rivetés.
