The top of the polymeric kettle body 5 is provided with a cover body 51, the top of the stirring shaft 1 is connected with a motor for driving the stirring shaft 1 to rotate around the central axis of the motor, and the motor is fixed on the cover body 51.

Referring to fig. 1, one end of the stirring blade 2 away from the stirring shaft 1 is fixedly connected with a fan blade 21, and the distance between one end of the fan blade 21 away from the stirring shaft 1 and the circumferential side wall of the polymeric kettle body 5 is less than 2 cm. The fan blades 21 rotate along with the stirring blades 2, the stirring range of the stirring paddle is expanded, the mixture close to the inner side wall of the polymerization kettle body 5 can be fully stirred, and the stirring uniformity is improved. The blade surface of the fan blade 21 is distributed with a plurality of through holes 22 in a rectangular array, so that the fluid resistance borne by the fan blade 21 is reduced.

In order to fully stir the mixture at the bottom of the polymerizer body 5, referring to fig. 1 and 2, a connecting block 4 is fixed at the bottom of the stirring shaft 1, an installation groove 42 extending in the vertical direction is formed in the top wall of the connecting block 4, a vertical rod 44 is welded to the bottom wall of the installation groove 42, and the vertical rod 44 is arranged in the vertical direction. The connecting block 4 is provided with a convex block 41, the top of the convex block 41 is hemispherical, and the bottom of the convex block 41 is inserted into the mounting groove 42 and slides along the depth direction of the mounting groove 42. The projections 41 are provided in plurality and uniformly distributed along the circumferential direction of the stirring shaft 1. The bottom wall of the projection 41 is provided with a sliding groove 45 along the vertical direction, and the upright 44 is inserted into the sliding groove 45 and is in sliding fit with the sliding groove 45. The upright rod 44 is sleeved with a spring 43, one end of the spring 43 is fixed with the bottom wall of the mounting groove 42, and the other end of the spring 43 is fixed with the bottom wall of the convex block 41. In the present embodiment, the spring 43 is preferably a compression spring. The projection 41 is pressed to compress the spring 43, and when the upright 44 abuts against the sliding groove 45, the rounded portion of the projection 41 is still located outside the mounting groove 42.

Referring to fig. 2 and 3, a sleeve 3 located above the connecting block 4 is sleeved on the stirring shaft 1, and the inner diameter of the sleeve 3 is larger than the diameter of the stirring shaft 1, so that the sleeve 3 can move on the stirring shaft 1. The outer side of the sleeve 3 is coaxially provided with a circular ring 31, the inner diameter length of the circular ring 31 is larger than that of the sleeve 3, and the distance between the outer circumferential side wall of the circular ring 31 and the inner circumferential side wall of the polymerization kettle is 3-5 cm. A plurality of connecting rods 32 with round longitudinal sections are arranged between the circular ring 31 and the sleeve 3, and the connecting rods 32 are arranged along the radial direction of the circular ring 31 and are uniformly distributed. The top position height of the bump 41 is higher than the bottom position height of the connecting rod 32, and the connecting rod 32 is in contact with the hemispherical side wall at the top of the bump 41. In this embodiment, the sleeve 3, the connecting rod 32, and the ring 31 are made of a metal material with a relatively high density, such as stainless steel.

After the motor is started, the stirring shaft 1 rotates, the connecting block 4 and the lug 41 rotate along with the rotating shaft, and the sleeve 3, the connecting rod 32 and the circular ring 31 are integrally provided with motion power through the fluid motion of the mixture, so that the rotating angular speed of the sleeve is smaller than that of the lug 41.
