Description

Technical Field

[0001] The utility model relates to a material stirring device, in particular to a material stirring assembly with an inflow grinding structure. Background Art

[0002] Patent document CN212215369U discloses a stirring device, which includes a stirring barrel, a secondary barrel and a vertical stirring assembly. The top of the stirring barrel has a feeding port. The vertical stirring assembly is vertically arranged and rotatably installed in the stirring barrel. The secondary barrel is fixedly connected to the outer wall of the stirring barrel. One side of the bottom of the secondary barrel is communicated with the stirring barrel. The top of the secondary barrel is open, and one side of its upper part has a discharge port. The stirring process of the slurry is always under high liquid level and full barrel stirring. The well-mixed slurry flows into the secondary barrel through the lower part of the side wall of the stirring barrel by the pressure in the barrel. The liquid level of the slurry in the secondary barrel is kept the same as that in the stirring barrel. In this way, the residence time of the slurry in the stirring barrel can be effectively extended, and the mixing quality of the slurry can be enhanced. However, this stirring device only uses a stirring impeller to stir the material. When the material contains large particles, it is difficult to remove them, resulting in poor particle size balance of the material and affecting the product quality. Therefore, it is necessary to optimize its structure to overcome the above defects. Summary of the Utility Model
