Description
Technical Field
[0001] The utility model relates to the technical field of pharmaceutical mixing devices, in particular to a pharmaceutical mixing device. Background Art
[0002] The production process of chemical drugs consists of two parts: raw material production and drug preparation production. The raw material is the material basis of drug production, but it must be processed into drug preparations suitable for consumption before it becomes a drug. In the pharmaceutical work, the drugs need to be mixed and processed, and the corresponding mixing equipment needs to be used during the mixing process.
[0003] When the existing pharmaceutical mixing device is installed and used, it is not convenient to crush and filter the agglomerated raw materials, and it is impossible to sieve them. If the agglomerated raw materials are not crushed, they will be mixed in and cause uneven stirring; when the length of the stirring rod is insufficient, the drugs are easy to hang on the inner wall of the mixing container or the drugs in the middle part of the container are not stirred sufficiently, and they are also easy to sink to the bottom, which easily leads to poor mixing effect; since the container cannot be driven to rotate, it is not easy to mix the drugs evenly with a simple stirring rod, and the mixing efficiency is slow, which brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a pharmaceutical mixing device. Utility Model Content
