The mixing assembly 6 includes a mounting plate 61 arranged on the side wall surface of the reactor shell 1 and an open slot 62 opened on the surface of the mounting plate 61. A rotating part 63 is mounted on the inner side of the open slot 62. The middle position of the sub-packaging tank 4 is provided with a main pipe body 43. The main pipe body 43 is arranged and distributed with a connecting rod 44 on both sides. The number of the connecting rod 44 is consistent with the number of the sub-packaging tank 4. The main pipe body 43 corresponds to the fixed collar 42 through the connecting rod 44. The lower surface of the middle end of the main pipe body 43 is provided with a swing rod 45.

[0027] In this embodiment, the central part of the inner bottom surface of the accommodating chamber 2 is provided with a positioning plate 46.
