[0002] Reactors are broadly understood as containers for physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions. The design conditions, processes, inspection, manufacturing, and acceptance must be based on relevant technical standards to achieve the heating, evaporation, cooling, and low-speed mixing reaction functions required by the process. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation. For example, reactors, reaction pots, decomposition pots, polymerization pots, etc. are generally made of carbon-manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials.

[0003] Existing deficiencies: Existing reactors usually adopt a method of evenly fixing multiple bolts on the outer ring of the reactor cover to achieve sealing and pressure resistance. However, the number of bolts in the bolt locking method of this type of reactor is too large, which makes the opening and closing of the reactor cumbersome and wastes a lot of time; secondly, the feeding inlet of the existing reactor is fastened with bolts, and the bolts need to be cumbersome to disassemble when feeding, which is not conducive to feeding.
