Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a stirring paddle for a polymerization kettle. Background Art

[0002] In the field of chemical equipment, especially in the polymerization process (polymerization reaction is a chemical reaction that combines two or more monomer molecules into a polymer compound), the design of the agitator is of great significance for improving production efficiency, reducing costs and ensuring product quality.

[0003] Traditional agitators simply stir high-viscosity materials, resulting in low efficiency and uneven mixing, which in turn affects product performance. Utility Model Content

[0004] The purpose of the utility model is to provide a stirring paddle for a polymerization kettle, aiming to solve the technical problem in the prior art that the stirring paddle only simply stirs when processing high-viscosity materials, resulting in low efficiency and uneven mixing, which in turn affects product performance.

[0005] To achieve the above-mentioned purpose, the utility model adopts a stirring paddle for a polymerization kettle, comprising a connecting shaft, a transverse plate, multiple first connecting plates, multiple second connecting plates and several plow-type shovel plates, one end of the connecting shaft is connected to an external power source, the connecting shaft has a groove, the transverse plate is fixedly connected to the groove, multiple first connecting plates and multiple second connecting plates are all fixedly connected to the transverse plate, and are all located below the transverse plate, and multiple second connecting plates are located at the position where the multiple first connecting plates are rotated 180 degrees along the axial center line of the connecting shaft, the lengths of the multiple first connecting plates decrease successively from the midpoint of the transverse plate to one end, and the lengths of the multiple second connecting plates decrease successively from the midpoint of the transverse plate to the end away from the first connecting plate, and the multiple first connecting plates and the multiple second connecting plates are all fixedly connected with the plow-type shovel plates.

[0006] Wherein, the first connecting plate and the plurality of second connecting plates are all arranged on the transverse plate in a deflected manner along the axial center line of the connecting shaft.

[0007] The angle between the plow blade and the corresponding first connecting plate is an obtuse angle, and the angle between the plow blade and the corresponding second connecting plate is also an obtuse angle.

[0008] Wherein, a plurality of the first connecting plates are equidistantly arranged on the transverse plate, and a plurality of the second connecting plates are also equidistantly arranged on the transverse plate.

[0009] Wherein, the stirring paddle for the polymerization kettle further includes two reinforcing plates, and the two ends of the reinforcing plates are fixedly connected to the connecting shaft and the transverse plate respectively.

[0013] Beneficial effects of the utility model:

[0014] The decreasing length design of the plurality of first connecting plates and the second connecting plates allows the stirring paddle to stir at different depths during rotation, thereby facilitating uniform mixing and dispersion of materials in the polymerization kettle. The plow-type shovel plate is suitable for polymerization kettles with curved bottoms. The plow-type shovel plate enhances the turning and mixing of materials and shovels the materials from the bottom of the kettle to prevent the materials from adhering to the bottom of the kettle.

[0015] The connection between the transverse plate and the groove of the connecting shaft provides structural stability, ensuring the stability and reliability of the stirring paddle under high rotation speed or high load.

[0016] The first connecting plate and the second connecting plate are arranged to be offset along the axial centerline of the connecting shaft, which helps to distribute the load of the plurality of first connecting plates and the plurality of second connecting plates and reduce damage caused by local overload;

[0017] By forming an obtuse angle between the plow-type shovel plate and the first connecting plate and the second connecting plate, the resistance of the material during the mixing process can be reduced, while the turning effect of the material is increased, thereby improving the mixing efficiency;

[0018] The invention solves the technical problem in the prior art that the stirring paddle only performs simple stirring when processing high-viscosity materials, resulting in low efficiency and uneven mixing, which in turn affects product performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Beneficial effects of the utility model:

[0043] The decreasing length design of the plurality of first connecting plates 103 and the second connecting plates 104 allows the stirring paddle to stir at different depths during rotation, thereby facilitating uniform mixing and dispersion of materials in the polymerization vessel. Furthermore, the plow-type shovel plate 105 is suitable for polymerization vessels with curved bottoms. The plow-type shovel plate 105 enhances the turning and mixing of materials and shovels the materials from the bottom of the vessel to prevent the materials from adhering to the bottom of the vessel.

[0044] The connection between the transverse plate 102 and the groove 106 of the connecting shaft 101 provides structural stability, thereby ensuring the stability and reliability of the stirring paddle under high rotation speed or high load.

[0045] The first connecting plate 103 and the second connecting plate 104 are offset along the axial centerline of the connecting shaft 101, which helps to distribute the load of the multiple first connecting plates 103 and the multiple second connecting plates 104 and reduce damage caused by local overload;
