Background

Norfloxacin, alternative names: licholruo, norfloxacin and linkexin. The chemical name of the compound is 1-ethyl-6-fluoro-1, 4-dihydro-4-oxo-7- (1-piperazinyl) -3-quinolinecarboxylic acid. The product is a third-generation quinolone antibacterial drug, can block the action of DNA gyrase of pathogenic bacteria in the digestive tract, block the DNA replication of the bacteria, and has an inhibiting effect on the bacteria. Is a common medicine for treating enteritis and dysentery. However, this drug has a delayed action on bone formation in juveniles and affects their development, so administration to juveniles is prohibited.

The production and preparation of norfloxacin require dichlorobenzene or nitrochlorobenzene to be mixed with various element materials and prepared by a series of chemical processes of nitration, reduction, reflux, heating, hydrolysis and the like, the chemical raw materials are usually powder, granule or liquid, when the norfloxacin is mixed, the traditional stirring and mixing equipment has large gaps between the stirring blades and the edge of the inner wall of a machine, the powder raw materials are easily accumulated at the gaps and cannot be well stirred, even if the stirring blades are lengthened, the powder raw materials cannot be too close to the inner wall of the machine due to circular motion during stirring, part of the raw materials cannot be stirred all the time, the stirring effect is undoubtedly reduced, the raw materials are poor in mixing, the subsequent preparation process is influenced, unnecessary waste is caused, and the production cost is increased.

The existing stirring equipment increases the performance of a stirring mechanism to improve the stirring quality, but the stirring mechanism can not stir all materials uniformly, so the most basic structure must be changed to ensure the stirring quality.
