[0042] The filter 5 can reduce the harmful substances in the exhaust gas in the inside of the reaction kettle body 1 directly discharged into the air, so as to play an environmental protection role.

[0043] The working principle of the present application is as follows: When the oxygen inside the reaction kettle body 1 needs to be discharged, the inert gas delivery fan (the inert gas delivery fan is not the improved technical solution of the present application, and the specific principle can be referred to the prior art) is connected with the inert gas delivery pipe 33, the storage tank for storing inert gas, and then the inert gas delivery fan is started.

The inert gas in the inside of the driving shaft 23 is delivered to the inert gas nozzle 35 through the inert gas delivery hose 36. The inert gas nozzle 35 delivers the inert gas to the inside of the reaction kettle body 1. As the inert gas in the inside of the reaction kettle body 1 gradually increases, the pressure in the inside of the reaction kettle body 1 gradually increases. When the pressure in the inside of the reaction kettle body 1 reaches a certain value, the oxygen and the mixed inert gas in the inside of the reaction kettle body 1 are discharged through the pressure relief device 50.

The bidirectional screw rod 44 drives the moving block 47 to move up and down along the guide rod 45. The moving block 47 drives the inert gas nozzle 35 to move up and down. In this way, the inert gas delivered to the inside of the reaction kettle body 1 is uniformly distributed. When the bidirectional screw rod 44 and the guide rod 45 rotate in a circle, the cleaning brush 49 on the one end position limiting wheel 48 of the bidirectional screw rod 44 and the guide rod 45 cleans the splashed reactants. The cleaned reactants are discharged from the limiting groove 410 through the discharge port 411. In addition, the bidirectional screw rod 44 drives the cleaning brush 49 on the one end position limiting wheel 48 of the bidirectional screw rod 44 to self-rotate in the process of rotating. The self-rotating cleaning brush 49 deeply cleans the inner side wall of the limiting groove 410 where the one end position limiting wheel 48 of the bidirectional screw rod 44 is located. The connecting plate 41 drives the stirring piece 8 to rotate in the process of rotating.
