Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a square paddle stirring device for a mixer. Background Art

[0002] Ribbon mixers are generally used for mixing sticky or cohesive powders and particles, and for adding liquids and paste-like materials to powders and particles. At the same time, due to the difficulty of cleaning sticky materials, they are suitable for mixing in situations where the output is large and the variety is not frequently changed. When the ribbon mixer rotates, the internal shaft rotates around the axis, thereby driving the square paddle blades to rotate, stirring and mixing the powder and liquid in the container. When the shaft rotates, the material will also rotate around the shaft in the container to form a vortex. Since the material rotates in the same direction as the shaft, this will cause local material dislocation and reduce friction, resulting in uniform mixing of local materials.

[0003] In the prior art, the problems of mixers are wear and tear and material turning. In the process of mixing materials, wear is inevitable. In addition, a screw belt is generally used to turn the materials, and the materials are mixed evenly through the screw belt. However, the work efficiency of turning the materials through the single method of screw belt is low, and it takes a long time to achieve the purpose of mixing evenly.
