[0002] Pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical products can be produced in ordinary chemical plants. As long as they reach a certain level, they can be used for drug synthesis. After years of development, the chemical raw materials and intermediates required for pharmaceutical production in my country are basically matched, and only a small part needs to be imported. In the production process of pharmaceutical intermediates, the solutions of pharmaceutical raw materials need to be mixed. At present, mixing devices are often used to mix pharmaceutical intermediates.

[0003] In the actual operation of mixing pharmaceutical raw materials, the agitator plays a vital role. However, with long-term use, a common and thorny problem gradually surfaced: some materials inevitably adhere to the stirring rod, which not only affects the stirring effect, but also poses a potential threat to the quality and purity of the medicine. The agitator usually works by fixing it on the output end of the motor. Although this installation method is stable and reliable, it also brings a series of operational inconveniences. Due to the complex structure of the agitator and the cumbersome disassembly process, users often face many difficulties in cleaning the adhered materials on the stirring rod. They have to spend a lot of time and energy, using various tools and methods to remove these stubborn materials, which not only increases the complexity of the operation, but also may affect the subsequent processing due to incomplete cleaning, and may even pose a potential risk to the quality and safety of the medicine.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
