What are the components of the stirred reactor?The stirred-type reactor was mainly composed of a stirrer and a kettle body. The agitators include the transmission device, the stirring shaft (including the shaft seal), and the impellers (stirring paddles); the kettle body includes the cylinder body, the jacket, the internal parts, the coil, the guide tube, etc. The reaction kettle could also be composed of a kettle cover, a transmission device, a shaft sealing device, a support, various pipes, and other parts. From its internal structure, it may include an electric motor, a decelerator, a frame, a manhole, a sealing device, a feed port, an upper head, a cylinder, a shaft, a stirring shaft, a jacket, a heat-carrying medium outlet, a baffling plate, a spiral guide plate, an axial-flow stirring device, a radial-flow stirring device, a gas dispenser, a lower head, a discharge port, a heat-carrying medium outlet, a gas outlet, etc.

Shaken Song MeaningThere were many songs called " Shaken," and the meaning of " Shaken " sung by different singers might be different. "Shaken," sung by Shiny Toy Guns, had lyrics such as "Running in circles, chasing pain of yesterday," which expressed the feeling of struggling in the pain of the past and waiting for relief. It was like waiting for things to pass despite being afraid, and also expressed the determination not to be affected by the outside world. M's "Shaken" didn't have a clear theme, but it was speculated from the lyrics that it might be related to a certain state of the individual's heart. Allan Jackson's "Shaken" didn't have enough information to show its exact meaning.

The difference between a reactor and a stirred tankThere were many differences between a reaction kettle and a stirred tank:
1. ** In terms of cost **: The reactor has a complex structure and a high cost, while the stirring tank has a simple structure and a relatively low cost.
2. ** In terms of structure **
- ** Top cover structure **: The top cover of the reaction kettle is a head structure or a conical structure; the top cover of the stirring tank can be a flat cover structure or a sealed structure.
- ** Overall structure **: The overall structure of the mixing tank is simpler than that of the reaction kettle. It is easy to manufacture and simple to use.
3. ** Sealing **: The reaction kettle has high requirements for sealing, so it needs to use mechanical seals; the sealing form of the stirring tank can be made into mechanical seals or packing seals according to requirements.
4. ** Operation observation **: The reaction kettle can only observe the materials in the tank with the assistance of the mirror, pressure gauge, level gauge and other accessories; the open-cover stirring tank can observe the materials in the tank through the opening of the cover or the manholes, and the observation range is larger than the observation range of the mirror of the reaction kettle.
5. ** Working conditions **
- ** Pressure **: The pressure resistance of the reactor is higher than that of the stirred tank. The reactor usually needs to work under a certain pressure. For example, the stirred reactor often needs to be installed with a mechanical seal to meet the requirements of vacuum packaging or work under a certain pressure. The stirred tank can be sealed with ordinary packing.
- ** Temperatures **: There is usually a reaction bed in the reactor and it can be treated at a high temperature to resist heat. For example, the temperature of the materials in the stainless steel reactor can reach 400 degrees Celsius, and the pressure in the reactor can be maintained at dozens of kilograms or even hundreds of kilograms. The stirred reactor is usually equipped with a constant temperature. The temperature of the materials in the porcelain reactor cannot exceed 200 degrees Celsius. If the temperature is too high, it will cause the glaze layer to melt.
- ** Function **: The reaction kettle can carry out reactions, and the reaction process is often accompanied by temperature changes. For example, the reaction kettle needs a heating jacket, or an air pipe to heat and cool; the stirring tank is generally only used as a stirring and mixing equipment, not involved in the reaction process, and usually does not need to be heated.
6. ** Stirring paddle types (related to the reaction kettle stirring equipment)**: The widely used stirring paddles in the reaction kettle include paddle type, propeller type, turbine type, anchor type, and frame type. Paddle-type agitators were mainly used to prevent solid settlement in solid liquids; propeller agitators were more commonly used in liquids with low stickiness; turbine agitators could basically complete all stirring operations and were suitable for fluids with a wider range of stickiness; anchor agitators and frame agitators had simple structures and were generally used in situations where mixing requirements were not too strict.
