Esterification reaction batching kettle

An esterification reaction batching kettle relates to the technical field of chemical engineering devices and comprises a barrel, an upper arc-shaped end cover and a lower arc-shaped end cover which are oppositely arranged are fixedly connected to an upper end opening and a lower end opening of the barrel respectively, a conical flow guide body is fixedly connected to the upper surface of the lower arc-shaped end cover, a rotating shaft is rotatably installed on the conical flow guide body, and bottom stirring blades are further arranged on the rotating shaft in a surrounding mode. The lower surface of the upper arc-shaped end cover is further coaxially and fixedly connected with a liquid separation ring pipe, and nozzles are arranged on the lower surface of the liquid separation ring pipe in a surrounding mode. The problems that in the prior art, a device is limited by the stirring mode, so that long-time reaction stirring is needed, and large working time is occupied are solved; the stirred materials are ea
