Chemical synthesis reaction kettle convenient for feeding

The utility model belongs to the technical field of reaction kettles, and particularly relates to a chemical synthesis reaction kettle convenient for charging, which comprises a kettle body, a kettle cover, a driving box, a driving pipe, a charging mechanism, a limiting mechanism, a stirring frame, an end cover, a sealing ring and a discharging cover, a driving pipe is mounted on the kettle cover through a bearing, a stirring frame is fixedly connected to the driving pipe, and a feeding mechanism is arranged in the driving box. According to the reaction kettle, the charging box, the air pump, the sealing cover and other structures are additionally arranged on the driving pipe, so that raw materials can be put into the charging box when charging is needed in the reaction process, and then the pressure in the charging box is increased through the air pump, so that the pressure in the charging box and the pressure in the kettle body are balanced; and then the electromagnetic valve is opened to feed the materials
