[0018] The utility model provides a stirring paddle for a polymerization kettle of viscous and dry materials, comprising a main shaft 1, a transverse plate 2, a plurality of left fixed plates 3, a plurality of right fixed plates 4, a plurality of left scrapers 5 and a plurality of right scrapers 6, wherein the transverse plate 2 is fixedly connected to the main shaft 1 and is located at the lower end of the main shaft 1, the plurality of left fixed plates 3 are respectively fixedly connected to the transverse plate 2 and are respectively located at the lower left end of the transverse plate 2, the plurality of right fixed plates 4 are respectively fixedly connected to the transverse plate 2 and are respectively located at the lower right end of the transverse plate 2, the plurality of left scrapers 5 are respectively fixedly connected to the lower ends of the corresponding left fixed plates 3, and the plurality of right scrapers 6 are respectively fixedly connected to the lower ends of the corresponding right fixed plates 4.

[0019] In this embodiment, the main shaft 1 is installed on the polymerization reactor, and the main shaft 1 rotates clockwise, driving the multiple left scrapers 5 and the multiple right scrapers 6 to stir the material inside the reactor. Since the multiple left scrapers 5 and the multiple right scrapers 6 are evenly arranged, when the multiple left scrapers 5 rotate to stir the material, the gaps between the multiple left scrapers 5 are exactly the paths for the multiple right scrapers 6 to rotate and stir, so that the multiple left scrapers 5 and the multiple right scrapers 6 are staggered and stirred respectively, thereby greatly improving the stirring efficiency and further improving the processing and production speed of the material.

[0020] Furthermore, the stirring paddle for the polymerization kettle of viscous and dry materials also includes two L-shaped rods 7, which are symmetrically arranged on both sides of the main shaft 1, and the lower ends of the two L-shaped rods 7 are fixedly connected to the upper ends of the horizontal plate 2; the bending angles of the multiple left scrapers and the multiple right scrapers are 35°-45°; the spacing L1 of the multiple left fixed plates is 8cm-10cm, the spacing L2 of the multiple right fixed plates is 8cm-10cm, the spacing L3 of the multiple left scrapers is 8cm-10cm, and the spacing L4 of the multiple right scrapers is 8cm-10cm.

When multiple left scrapers 5 or multiple right scrapers 6 rotate and stir for a long time, a large amount of material will accumulate on one side. At this time, the material will pass through the gap between the corresponding L-shaped rod 7 and the main shaft 1, and then flow to the other side of the horizontal plate 2 to continue stirring, thereby improving the stirring efficiency of the device.
