Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a powder recovery device used for pharmaceutical production. Background Art

[0002] In the pharmaceutical production process, some incomplete granules or tablets need to be ground and then punched to form a new tablet. However, when the incomplete granules or tablets are ground, a large number of granules and tablets are difficult to recycle.

The powder recovery device for pharmaceutical production sucks the drug powder into the recovery bin through the suction head of the induced draft fan, the air blown out by the air pump fills the box, the heating rod in the box heats the cold air, and the hot air is transported to the recovery bin through the air outlet pipe. The stirring rod drives the blades to stir the drug powder so that it is fully exposed to the hot air and evenly dried. After drying, the valve of the pipeline connecting the recovery bin and the storage box is opened to make it fall on the filter plate, large particles of drugs are screened out, and fine drug powder falls into the lower layer, which solves the problem that a large amount of powder generated in drug production is exposed to the outside, absorbs moisture in the air and gets damp, and cannot be directly used after recovery, and is convenient for users to use.

[0004] The above-mentioned grinding of tablets in the form of stirring can crush the medicine, but it takes a long time to stir the medicine into powder, and thus there is a problem of low grinding efficiency. At the same time, when the medicine powder is recovered, a large amount of medicine powder will adhere to the inner wall of the feeding pipe, thereby causing a waste of resources. Therefore, the above problems need to be improved. Utility Model Content
