[0002] The stirring cooling reactor is a kind of equipment widely used in chemical, pharmaceutical, food and other industries. It is mainly used to stir and mix materials while cooling them. Constant temperature cooling media is injected through the reactor interlayer to refrigerate the materials in the reactor. The stirring reaction is carried out under normal pressure or negative pressure conditions according to the use requirements. The stirring device makes the materials fully mixed in the tank, increases the contact area between the materials, improves the reaction efficiency, and makes the cooling process more uniform.

[0038] Working principle of the present invention:

[0039] First, oil is transported to the mixing barrel through the oil inlet and outlet pipes. When the oil reaches a certain volume, the transport stops. The cold air enters the cavity between the mixing barrel and the second shell through the cold air inlet and outlet pipes. Part of the cold air enters the cooling stirring rod and the cooling stirring branch pipe through the cold air delivery pipe in the support base.

[0040] An external motor located at the bottom of the second shell drives the rotating rod. One end of the rotating rod penetrates the conveying base, the mixing barrel, the built-in base, and the cooling and stirring support rod, which in turn drives the internal stirring mechanism to cool and stir the oil in the middle. By setting up a hollow stirring mechanism in the mixing barrel, the loose cold air not only cools the periphery, but also adds a highly efficient cooling and stirring component inside the device. The outer wall of the mixing barrel is evenly wrapped with multiple layers of condenser tubes. The original traditional single cooling and stirring heat dissipation is expanded to multiple cooling and stirring methods, which improves the overall heat dissipation efficiency of the device.

[0041] Then, by arranging a shell part three in the reaction tank, a hot gas conveying pipe is fixedly connected to the side of the shell part three close to the shell part one, and a movable pressure valve is fixedly connected to the side of the shell part one away from the shell part two. When the oil is poured into the mixing barrel, a large amount of hot gas is generated in the upstream layer of the barrel. After the movable pressure valve is opened, the hot gas can be centrally evacuated through the hot gas conveying pipe, and it is not easy to bring out the oil particles generated by stirring in the mixing barrel. The hot gas in the hot gas conveying pipe is then extracted through the movable pressure valve on the top of the shell part one to fully reduce the pressure and temperature in the reaction tank.

[0042] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device that performs control such as a computer.
