[0032] The mixing mechanism includes a sealing cover plate 3, which is fixedly connected to the top of the mixing tank 2. A frame 4 is fixedly connected to the top of the middle part of the sealing cover plate 3. A gearbox 5 is fixedly connected to the top of the frame 4. A stirring motor 6 is fixedly connected to the input end of the gearbox 5. A coupling 7 is fixedly connected to the output end of the gearbox 5. A stirring shaft 8 is fixedly connected to the end of the coupling 7 away from the gearbox 5. Two mounting seats 9 are fixedly connected to the middle of the stirring shaft 8. Multiple evenly distributed stirring paddles 10 are threadedly connected to the outer walls of the two mounting seats 9. A cavity 11 is opened on the outer side of the middle part of the mixing tank 2. A heating coil 12 is installed in the cavity 11.

Multiple evenly distributed gaskets 22 are arranged on the outer wall of the frame 4. A connecting bolt 23 is threadedly connected to the middle of each gasket 22.

[0033] Specifically, by setting multiple evenly distributed gaskets 22 on the outer side wall of the frame 4, and installing connecting bolts 23 in the middle of the gaskets 22 by threaded connection, the frame 4 and the equipment installed on its top are fixed to the sealing cover plate 3.

[0034] Referring to Figure 1, the conveying mechanism includes two reagent storage tanks 14, both of which are located on the left and right sides of the middle of the reactor body 1.
