Description

Technical Field

[0001] The present application relates to the technical field of stirring equipment, in particular to a stirring device for synthesis of 2-bromo-4-nitroimidazole. Background Art

[0002] In the synthesis process of 2-bromo-4-nitroimidazole, the commonly used stirring equipment is mainly a stirring device matched with a reaction kettle. The reaction kettle is a common chemical synthesis equipment, and the stirring device inside it plays a key mixing role.

[0003] In the prior art, during the use of stirring equipment, a single mechanical stirring mode is mostly adopted. For working conditions involving multi-phase reactions, it is difficult to achieve efficient mass transfer and heat transfer. Reaction mixtures tend to accumulate in stirring dead corners, leading to excessive local reactions, increased by-products, and affecting product quality and yield. Therefore, we propose a stirring device for synthesis of 2-bromo-4-nitroimidazole to solve the above problems. Utility Model Content

[0011] Furthermore, a third sprocket is fixedly installed at the other end of the rotating rod, and a fourth sprocket is fixedly installed at one end of the spiral conveying rod. The third sprocket and the fourth sprocket are meshed with the same second chain. When the rotating rod rotates, the third sprocket drives the fourth sprocket to rotate through the second chain.
