[0002] The double-layer glass reactor is designed with double-layer glass. The inner layer can be placed in the reaction solvent for stirring reaction, and the interlayer can be connected to different cold and heat sources (refrigerated liquid, hot water or hot oil) for circulating heating or cooling reaction. Under the set constant temperature conditions, in the closed glass reactor, stirring reaction can be carried out under normal pressure or negative pressure conditions according to the use requirements, and the reaction solution can be refluxed and distilled. It is an ideal pilot and production equipment for modern fine chemical plants, biopharmaceuticals and new material synthesis.

[0003] After searching, the high and low temperature double-layer glass reactor with announcement number CN211051505U includes a reactor body, a motor is fixedly installed on the top of the reactor body, and the output end of the motor is fixedly connected to a stirring shaft, the other end of the stirring shaft passes through the top of the reactor body and extends downward, and the stirring shaft is rotatably connected to the top of the reactor body, and a plurality of evenly cross-distributed stirring paddles are fixedly welded on the outer wall of the stirring shaft, an aeration pipe is fixedly connected to the bottom end of the stirring shaft, and a plurality of evenly distributed aeration ports are fixedly connected to the top of the aeration pipe, and an aeration generator is fixedly installed on the outer wall of the reactor body, and the output end of the aeration generator is fixedly connected to a gas supply pipe, and the other end of the gas supply pipe passes through the reactor body and extends to its inner cavity. The utility model allows the raw materials in the double-layer glass reactor to be fully and evenly mixed, thereby effectively improving the reaction effect, and is convenient for filtering the generated solvent to avoid affecting the purity of the solvent;

[0004] Based on the above patent, by starting the motor and the aeration generator, the motor drives the stirring paddles evenly distributed on the stirring shaft to rotate, and at the same time, drives the connecting pipe connected to the aeration pipe and the gas pipe to rotate.
