The oil liquid passing through the first double pipe 7 and the second double pipe 8 can be cold oil or hot oil according to actual requirements.

The pipeline of the double-pipeline reaction kettle is designed into two pipelines. According to the actual stirring condition, the reaction kettle only needs to stir a small amount of materials. When a small amount of materials are stirred, if the pipeline of the reaction kettle is designed as a pipeline. At this time, the upper pipeline is heated, and the heat of the upper pipeline cannot be transferred to the material. When the material discharging pipeline 21 discharges materials, a small amount of materials can be adhered to the upper pipeline, the upper pipeline cannot be cleaned, and the upper pipeline is damaged by the small amount of materials. Designing a two-way pipe to avoid such a situation avoids such a situation.

When a small amount of materials are stirred in the double-pipeline reaction kettle, only the second double pipeline 8 needs to be opened.

The heat preservation layer 9 is internally processed with a plurality of groups of heat preservation baffles 91 at uniform intervals. The heat-insulating layer 9 further comprises a heat-insulating liquid inlet and a heat-insulating liquid outlet.

The heat preservation liquid inlet is responsible for flowing into heat preservation fluid. The heat preservation liquid outlet is responsible for flowing out the heat preservation fluid. The heat preservation layer 9 plays a role in preserving heat for the bottom of the main body 2. The design of the multiple sets of heat-insulating baffles 91 can limit the flow of heat-insulating oil. The temperature of the heat preservation oil liquid can not drop suddenly.
