Abstract
A system and an associated method for starting up stirring machines in a sediment in a controlled manner are provided, which system has the following: a container for receiving materials to be processed; a stirring device with stirring blades for stirring the materials to be processed in the container; a purging device; and a device for operating stirring machines. The purging device is arranged in such a way and set up so as to feed a medium for purging to a deposited sediment. Furthermore, a control is provided which initiates controlled re-starting of stirring machines after purging.

A system for starting up a stirring machine in a sediment in a controlled manner, comprising:
- a container for receiving a material to be processed;
- a stirring device having stirring blades for stirring the material to be processed in the container;
- a purging device configured to convey to a deposited sediment a medium for purging the sediment;
- a device for operating the stirring machine;
- and
- a control configured to initiate a controlled re-start of the stirring machine after purging has been effected.
A method for starting up a stirring machine in a sediment in a controlled manner, comprising the steps in the order of:
- after ascertaining a malfunction of the stirring machine and an accompanied sedimentation of a material to be processed in a container, intermittently purging lances in a supply line with a purging medium;
- fluidizing the sediment by purging with pressurized air or with the purging medium;
- starting up the stirring machine in reverse mode during the fluidizing step;
- stopping the fluidizing step while continuing the reverse mode;
- briefly halting operation of the stirring machine and operating the stirring machine in a standard rotational direction;
- and
- operating the stirring machine in a normal mode.
