Abstract
A stirring body has a hyperboloid-like or truncated cone-like form and a central connector piece for connection to a stirring shaft. To simplify the production of the stirring body and to reduce the transport outlay, it is proposed for the stirring body to be formed from a plurality of segments which are interconnected along joining zones extending from a peripheral edge in the direction of the connector piece.
Claims21
A stirring body having a hyperboloid or truncated form, comprising:
- a central connector piece for connecting to a stirring shaft;
- and
- a plurality of segments,
- wherein the stirring body has an upper side, a peripheral edge, and an underside,
- each of the plurality of segments has a first joining portion with a first joining profile on a longitudinal edge thereof and a second joining portion with a second joining profile on another longitudinal edge thereof,
- the first joining profile and the second joining profile form in an interconnected state joining zones extending from the peripheral edge to the connector piece,
- a contour of the second joining profile corresponds with a contour of the first joining profile in such a way that an underside of one of the plurality of segments connects with another underside of another one of the plurality of segments to form an overall flat contour forming the underside of the stirring body when the plurality of segments is assembled.
