Description

Technical Field

[0001] The present application relates to the technical field of medicine mixing, and in particular to a medicine efficient mixing device. Background Art

[0002] In the fields of environmental protection Fenton advanced oxidation, it is often necessary to mix multiple reagents to achieve a specific effect; efficient reagent mixing is crucial to ensure drug quality and production efficiency. The traditional manual mixing method is not only labor-intensive and inefficient, but also difficult to achieve precise control, which in turn affects the quality consistency of the final product. Therefore, in recent years, the application of automated reagent mixing devices has become more and more widespread, aiming to improve mixing efficiency while ensuring the stability and controllability of reagent quality.

[0003] Common automated pharmaceutical mixing devices mainly use a barrel structure and a stirring mechanism to achieve liquid mixing. Such devices usually include a barrel with a stirring blade, which is driven by an external motor to rotate to promote liquid mixing. Although these devices can basically meet daily production needs, there are still some shortcomings in actual application.

[0004] For example, existing pharmaceutical mixing devices often use a single-position feeding method when adding liquid ingredients, which can easily lead to uneven distribution of materials in the cylinder. Especially when dealing with viscous or complex pharmaceutical ingredients, simple feeding will lead to uneven mixing, affecting the quality and consistency of the final product.
