Description

Technical Field

[0001] The utility model relates to the technical field of drug production, and more specifically to a mixing device for drug production. Background Art

[0002] In the existing drug production and preparation process, many drug preparations are composed of two or more components. The physical mixing of drug preparations is a common technical means and process in the pharmaceutical process. Therefore, drug mixing devices are used in the drug production process to mix drugs of different types and forms.

[0003] For example, a mixing device for the production and processing of pharmaceutical preparations with announcement number CN220737221U includes a mixing box, a collecting box is arranged on the top of the mixing box, an exhaust assembly is arranged on the top of the collecting box, a hollow tube is penetrated and rotatably connected at the middle position of the top of the mixing box, a cleaning assembly 1 for cleaning the inner wall of the mixing box is arranged on both sides of the hollow tube, a driving assembly for driving the hollow tube to rotate is arranged on the top of the mixing box, and a partition is arranged inside the collecting box. The utility model can clean and collect the residual powder on the inner wall of the mixing box through the coordinated use of structures such as the collecting box, the hollow tube, the cleaning assembly 1, the collecting tube, the collecting drawer and the exhaust assembly, so as to facilitate the recycling of the residual powder on the inner wall of the mixing box, avoid the waste of medicinal materials, and reduce the pharmaceutical cost of the enterprise.

[0004] The drug mixing device proposed in the above patent document cannot pre-grind and crush the solid drug in actual use, which makes it difficult for some poorly soluble solid drugs to be internally fused with liquid raw materials in a short time, thus affecting the mixing processing speed of the drug. Therefore, it is necessary to improve the existing problems of the mixing device. Utility Model Content
