The structure and connection relationship of the rest parts are the same as those described in any of the foregoing embodiments, and are not described herein again to avoid the tedious text.
On the basis of the above embodiments, the present invention continues to describe the technical features and functions of the technical features in the present invention in detail to help those skilled in the art fully understand the technical solutions of the present invention and reproduce them.
In the present invention, the connection flange a302 of the fixing base 3 and the connection flange B402 of the stirring blade 4 are reliably connected by a plurality of sets of bolt fasteners, and the contact surfaces of the positioning circular plate a303 and the positioning circular plate B401 can be pressed and attached by the connection pressure of the bolt fasteners. Axial displacement of the fixed seat 3 and the stirring blade 4 is limited by the plurality of groups of bolt fasteners, circumferential rotation of the fixed seat 3 and the stirring blade 4 is limited by friction force between contact surfaces of the positioning circular plate A303 and the positioning circular plate B401, and in the process that the stirring blade 4 rotates along with the fixed seat 3, radial load transmitted to the stirring blade 4 by stirring slurry increases friction force between the positioning circular plate A303 and the positioning circular plate B401, so that circumferential rotation between the fixed seat 3 and the stirring blade 4 is limited.
In the utility model, the inclination angle between the stirring blade 4 and the fixed seat 3 is adjusted by loosening the bolt fastener, and the bolt fastener 4 can be made of stainless steel materials so as to avoid the corrosion of the bolt fastener 4 in the slurry stirring process.

In order to avoid that the stirring blades 4 and the stirring shaft body 2 bear bending load, the inclination angles of the two stirring blades 4 which are separated by 180 degrees in the same group are the same.
Particularly, in order to avoid the deposition of the high-density materials to the bottom of the storage tank, the inclination angle of the stirring blade 4 close to the bottom of the charging bucket is properly increased to increase the stirring force relative to the stirring blade 4 far away from the bottom of the storage tank, so that the upward flowability of the high-density materials is increased.
Particularly, before slurry enters the storage tank, the stirring work is started, the slurry enters the storage tank while being stirred at a constant speed, and the stirring load is gradually increased, so that the phenomenon that the stirring power unit is damaged and driven due to overlarge load when the slurry is started in a full load manner is avoided.
Finally, although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description of the present description is for clarity reasons only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
