AGITATOR SHAFT OF A FERMENTER AND METHOD FOR FASTENING AGITATING ARMS

摘要

In the case of an agitator shaft of a fermenter of a biogas plant, including agitator brackets, which are arranged on a shaft wall and on which at least one agitating arm, including an agitating arm fastening portion and a blade carrier can be connected to the agitator brackets by fastening two agitating arm fastening plates of the agitating arm, it is intended to provide a method that achieves easier and quicker assembly of an agitator shaft and integration in a fermenter in situ, whereby a considerable cost saving in the setting up of a fermenter is achieved. This is achieved by cutting out fastening holes in the agitator brackets and cutting out through-holes in the agitating arm fastening plates in such a way that a plurality of retaining ring bolts can be arranged so as to pass completely through the fastening holes and the through-holes and can be riveted therein.

主权项

1. An agitator shaft of a fermenter of a biogas plant with at least one agitator bracket arranged on a shaft wall and on which at least one agitating arm, comprising an agitating arm fastening portion and a blade carrier is connectable by means of fastening on at least one agitating arm fastening plate of the agitating arm on the at least one agitator bracket
wherein fastening holes are recessed in the at least one agitator bracket, and through-holes are recessed in the at least one agitating arm fastening plate so that a plurality of retaining ring bolts can be arranged so as to pass completely through the fastening holes and the through-holes and can be riveted therein.
