[0002] In the modern chemical industry, closed chemical reactors occupy a vital position. It is one of the key equipment for various chemical reactions and is widely used in many fields. With the continuous development of the chemical industry, the requirements for reactors are also increasing. The emergence of closed reactors provides a stable, reliable and controlled reaction environment. The early reaction devices were relatively simple and had many deficiencies in control accuracy and safety. The closed chemical reactor effectively solves these problems through advanced design and technology. It has good sealing performance, can prevent the leakage of reactants and products, and ensure the safety and environmental friendliness of the production process. At the same time, it can accurately control the reaction conditions. However, the existing closed chemical reactors usually have sealing rings at the opening and closing for sealing. Due to the corrosiveness of chemicals, the sealing rings may age and crack over a long period of time, resulting in poor sealing, thereby causing gas leakage, reducing the safety and work efficiency of the reactor. In order to solve the deficiencies of the existing technology, we propose a closed chemical reactor. Utility Model Content
