Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical intermediate processing, and particularly relates to a pharmaceutical intermediate concentration and filtering device. Background Art

[0002] Pharmaceutical intermediates are some chemical raw materials or chemical products used in the process of drug synthesis. Pharmaceutical intermediates may contain a certain amount of impurities. Therefore, pharmaceutical intermediates need to be concentrated and filtered to filter out the internal impurities before use.

[0003] When pharmaceutical intermediates are concentrated and filtered, they are usually first concentrated in a concentration tank and then discharged into a filter box for filtration. After concentration, the pharmaceutical intermediates will become very viscous. Since most devices discharge the concentrated pharmaceutical intermediates through smaller pipes, some of the pharmaceutical intermediates will remain in the concentration tank. When there are too many pharmaceutical intermediates remaining in the concentration tank, the concentration efficiency of the subsequent pharmaceutical intermediates that need to be concentrated will be reduced. Utility Model Content

By setting a discharge component, no concentrated pharmaceutical intermediate will remain in the concentration tank, which solves the problem that most existing devices discharge the concentrated pharmaceutical intermediates through smaller pipes, resulting in a portion of the pharmaceutical intermediates remaining in the concentration tank. When too much pharmaceutical intermediate remains in the concentration tank, the concentration efficiency of the pharmaceutical intermediates that need to be concentrated later will be reduced.
