Reaction kettle for processing hydroxyethyl methylacrylate

In the process of realizing the scheme, the inventor finds that the following problems in the prior art have not been well solved: 1. During the use of the device, when the reaction kettle is stirring and processing hydroxyethyl methacrylate, methyl Hydroxyethyl acrylate generates heat during the stirring process and easily produces hydroxyethyl methacrylate vapor. The lack of recovery control leads to low operational safety of the reactor when producing hydroxyethyl methacrylate; 2. During the use of the device The reaction kettle adopts a closed structure consisting of a shell cover and an outer shell, and cooperates with the first branch pipe, the second branch pipe, the first vacuum pump and the second vacuum pump to create a vacuum environment in the first reaction zone and the second reaction zone inside the reaction kettle. The operation process stops when the stirring shaft is working, and it is impossible to adjust the high-temperature boost that occurs during the stirring process of hydroxyethyl methacrylate, and the air pressure adjustment inside the reactor is insufficient; 3. During the use of the device, the hollow Ventilation holes and liquid outlets are set on the first stirring shaft and the second stirring shaft of the structure, resulting in low convenience for later use and maintenance of the rotating structural parts of the device, and there is a cleaning dead angle, which makes it impossible to complete quick maintenance and cleaning treatment
