The top of the device is fixedly connected to the output shaft of the motor 1. The stirring rod 11 passes through the support member 18 and is rotatably connected to the support member 18. An auxiliary ring 8 is fixedly connected to one side of the support member 18. An annular tube 17 is embedded inside the auxiliary ring 8. One end of the annular tube 17 is fixedly connected to a nozzle 19. One end of the nozzle 19 passes through the side wall of the auxiliary ring 8. A connecting pipe 16 is fixedly connected to the top of the annular tube 17. One end of the connecting pipe 16 passes through the side wall of the auxiliary ring 8 and the sealing cover 2 in sequence. A stirring blade 13 is inserted through the outer ring surface of the stirring rod 11. The stirring blade 13 is connected to the stirring rod 11 by bolts.

[0025] The support frame 10 can be used to reinforce the arc-shaped scraper 9. The connection between the stirring rod 11 and the support frame 10 can realize the synchronous rotation of the support frame 10 and the stirring rod 11. The motor 1 can provide power for the rotation of the stirring rod 11. The fixed block 14 can realize the connection between the scraper 15 and the support frame 10. The scraper 15 and the arc-shaped scraper 9 can increase the contact area with the inner wall of the mixing vessel body 5, thereby achieving scraping of the inner wall of the mixing vessel body 5 and reducing the accumulation and residue of materials on the inner wall of the mixing vessel body 5. The stirring blade 13 can assist in stirring the materials. The support member 18 can support the auxiliary ring 8. When the stirring rod 11 rotates, the support member 18 and the auxiliary ring 8 do not rotate. The auxiliary ring 8 can be used to reinforce the annular pipe 17 and the nozzle 19. The connecting pipe 16 can ensure a stable supply of water inside the annular pipe 17. The water discharged through the nozzle 19 can assist in cleaning the inside of the mixing vessel body 5.

[0026] Example 2: Figures 1-3 As shown, the bottom of the fixing block 14 is rotatably connected to the mixing vessel body 5. The bottom of the mixing vessel body 5 is fixedly connected to a discharge pipe. The outer ring surface of the mixing vessel body 5 is fixedly connected to an electrical control box 4 and an alarm 3. The electrical control box 4 and the alarm 3 are electrically connected. The alarm 3 is electrically connected to a temperature sensor 7. A reinforcing ring 12 is fixedly connected to one side of the temperature sensor 7. One side of the reinforcing ring 12 is connected to the inner wall of the sealing cover 2 by bolts.

[0028] The operating method and working principle of this device are as follows: First, the decabromodiphenyl ethane raw material to be processed is placed into the mixing tank body 5. The sealing cover 2 is installed on the top of the mixing tank body 5 and locked. The stirring rod 11 is driven by the motor 1 to rotate. The stirring blade 13 and the arc-shaped scraper 9 rotate with the stirring rod 11 to stir the raw material inside the mixing tank body 5. During stirring, the temperature sensor 7 is used to detect the temperature inside the mixing tank body 5. The controller inside the electrical control box 4 receives the signal. When the temperature is higher than the predetermined value, the alarm 3 sounds an alarm. When the air pressure inside the mixing tank body 5 is higher than the predetermined value, the pressure relief valve 6 automatically opens to relieve the pressure inside the mixing tank body 5.

[0029] After mixing, the material can be discharged by opening the discharge pipe at the bottom of the mixing vessel body 5. The motor 1 is started to continue mixing the material. The arc-shaped scraper 9 and the support frame 10 contact the inner ring surface of the mixing vessel body 5 to scrape the side wall of the mixing vessel body 5. When the scraper 15 rotates synchronously with the support frame 10, the bottom of the scraper 15 scrapes the bottom of the inner cavity of the mixing vessel body 5, reducing the material residue on the inner wall of the mixing vessel body 5. Then, the drain pipe on one side of the mixing vessel body 5 is opened, and water is supplied to the inside of the annular pipe 17 through the water source connected to the external water source of the connecting pipe 16. The water flow is sprayed out through the nozzle 19 to rinse the inside of the mixing vessel body 5 and the side wall of the arc-shaped scraper 9. The sewage is discharged through the drain pipe.
