A stirring device, in particular an axially conveying stirring device, is proposed for stirring, mixing, homogenizing, dispersing and/or suspending in particular abrasive media, with at least one stirring blade which is configured to rotate about a rotary axis, and with a contour unit which is configured for reducing wear-down of the at least one stirring blade.

Stirring device

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 controller is provided which initiates controlled re-starting of stirring machines after purging.

System and method for starting up stirring machines in a sediment

A stirring device has at least one at least substantially metallic stirring blade carrier and a plurality of stirring blades, which are connected to the stirring blade carrier, wherein the stirring blades are at least substantially made of a non-metallic material, wherein the non-metallic material is a ceramic material, wherein the stirring blades are releasably connected to the stirring blade carrier, wherein it is possible to release and/or establish a mechanical, namely a negative-fit and/or positive-fit connection between the stirring blades and the stirring blade carrier in a damage-free and/or non-destructive manner, and wherein the stirring blade carrier comprises at least one recess, which is configured to at least partly accommodate at least one of the stirring blades. The recess comprises at least one partial region implemented in a contiguous fashion if viewed in parallel to a rotational axis of the stirring blade carrier.

An agitator, particularly for abrasive media includes a support disk to which agitator blades are connected substantially perpendicular to the support disk. The blades are arranged substantially in a radial direction. The support disk also includes a hub that receives an agitator shaft which is preferably motor-driven. The trailing faces of the blades of the agitator and/or the area of the blade connections to the support disk are designed to largely prevent vortex shedding. This is accomplished by implementing a specific geometry for the agitator blades, the support disk, and the connection of the blades to the support disk.
