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.

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.

Stirred Reaction Tank Selling PriceAccording to the reference materials, the price of the double-layer glass reactor was 3000 yuan. The price of the double-layer glass reactor was 1 yuan. The stainless steel double-layer reactor 5L high-pressure reactor in Zhengzhou was 7125 yuan. The second-hand 2000-liter porcelain reactor in Liangshan was 12,000 yuan. However, the price of stirred reactors of different types, specifications, and manufacturers would vary.

Silence is the reason for choosing silenceA person might choose to remain silent for the following reasons:
1. ** Mental state **
- ** Happiness and comfort **: When a person feels happy and comfortable in front of others, they may be talkative and talk a lot of nonsense. On the other hand, if a person spoke less nonsense, they might not be happy, but they might also choose to remain silent.
- Disappointment: When you are disappointed with someone or something, such as facing various situations and opinions, even if it is criticized and slandered, you are indifferent. It is not that you are not eloquent or unreasonable, but you are so disappointed that you don't want to talk. Silence becomes an expression.
- [Understand your position in the other person's heart: When you know that you are insignificant in the other person's heart, you will choose to remain silent when you feel that there is no point in talking to someone who doesn't care about you.]
- [Distrust: As your experience increases, you may no longer trust others easily. You can't speak your mind to anyone, so you choose to remain silent.]
- ** Don't want to disappoint yourself **: If you get a neutral response when you confide in someone, in order to avoid disappointment, you will no longer express yourself and remain silent.
2. ** In terms of interpersonal relationships **
- ** Weakened in a relationship **: Words are insignificant in a relationship, and they have even been criticized for speaking out. They will choose to remain silent in order to protect themselves.
- ** Disdain to care **: After experiencing many things, I feel that some things are not worth arguing about. In order to gain peace, I no longer care about them and remain silent.
- [Disdain to Explain]: Sometimes, the more you explain, the less trust you get. For those who deliberately doubt you, you don't need to explain. Just wait for the right time.
3. ** In terms of personal growth and accomplishment **
- [Too much stress in life: As I grow older, I have to take on many roles in my life. The pressure increases. I feel that talking will only increase my troubles and I can't express it. Therefore, I choose to recover in silence.]
- [Appearance of accomplishment and maturity: Knowing that there are some things you shouldn't say and some things you shouldn't say. Silence is a form of respect for others and also an expression of accomplishment and maturity.]
4. ** Mental defense mechanism **
- ** Silence Effect **: When some people were young, their needs were not responded to. When they said their needs, they were criticized instead, forming a vicious cycle. When they grew up, they might become silent because of this self-protection and self-digestion consciousness. They had something to say but did not know how to say it.
