[0029] Reference Figure 1In the embodiment, the bottom end and the middle position of the stirring shaft 22 are respectively provided with stirring paddles 23, and the synergistic effect of the double-layer stirring paddles 23 can generate more vortex and shear force, so that more complex flow patterns are formed in the mixing process of the materials, the mixing efficiency is improved, the materials are mixed in a full range of directions, a random optimal motion state is formed, higher mixing uniformity is achieved, and the mixing efficiency of the materials is improved. The outer edge of the stirring paddle 23 at the bottom end is provided with a draft tube 24, and the draft tube 24 can reduce the shear flow of the bottom end stirring paddle to a certain extent, fully utilize the axial flow and radial flow of the paddle, promote the up-down exchange of the fluid, form up-down circulating flow inside and outside the draft tube 24, reduce the bottom dead angle in the kettle body 10, fully utilize the effective volume in the kettle body 10, prevent liquid flow short circuit phenomenon, and enhance the circulating capacity.

[0030] Reference Figure 2 and Figure 4 In the embodiment, the baffle device 30 is provided with two sets of left and right, which are symmetrically arranged on the inner walls of the kettle body 10. Of course, the number of the baffle device 30 can be set according to the actual situation, which should belong to the protection range of the utility model.

[0031] Reference Figure 3 and Figure 6 The baffle device 30 comprises a support seat 31, an adjusting screw 32 and a baffle 33. The support seat 31 is provided with two and is fixedly arranged at the upper and lower ends of the inner wall of the kettle body 10. The adjusting screw 32 is rotatably installed on the support seat 31. The baffle 33 is in sliding fit with the support seat 31. Specifically, the baffle 33 is arranged in parallel with the axis of the kettle body 10. One side of the baffle 33 is in sliding connection with the support seat 31, so that the baffle 33 can move in the axial direction of the kettle body 10. By adjusting the position of the baffle 33 in the kettle body 10, the dead angle and blind area caused by the fixed position of the baffle 33 can be avoided, so as to ensure the normal reaction and avoid the occurrence of side reaction.

[0032] The baffle 33 is fixedly connected with an adjusting seat 34, and the adjusting screw 32 is in threaded connection with the adjusting seat 34. In actual use, by rotating the adjusting screw 32, the adjusting seat 34 can be moved up and down. Since the baffle 33 is in sliding connection with the support seat 31, the height of the baffle 33 in the kettle body 10 can be adjusted.

[0035] In the initial state, the heights of the baffles 33 in the two sets of baffle devices 30 in the kettle body 10 are preferably different, that is, the top end of one baffle 33 is higher than the top end of the other baffle 33. Through the arrangement of the high and low baffles 33, the material can form a circulating flow in the kettle body 10, thereby improving the mixing effect of the material, ensuring the mixing effect of the material, improving the reaction efficiency, avoiding the side reaction caused by uneven mixing of the material, making the chlorine content of the produced chlorinated polyethylene particles uniform, and improving the product quality.
