Description

Technical Field

[0001] This utility model relates to the field of air classifier technology, specifically to an air classifier for traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine decoction pieces are prescription drugs that have been processed and can be directly used in clinical dispensing or preparation production in traditional Chinese medicine. During the production of traditional Chinese medicine decoction pieces, a large number of debris and impurities are mixed in, which need to be processed to improve the quality of traditional Chinese medicine decoction pieces.

[0003] In current methods of impurity removal from traditional Chinese medicine (TCM) decoction pieces, the TCM decoction pieces are typically poured into an air separator. The air separator removes debris and impurities. However, in practice, the large volume of decoction pieces results in small gaps between them, leading to incomplete removal of debris and impurities during air separation. This necessitates secondary or multiple processing steps, reducing the efficiency of debris and impurity removal and ultimately resulting in unsatisfactory performance. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a Chinese herbal medicine decoction piece air separator, which solves the problem that when Chinese herbal medicine decoction pieces are air-separated to remove impurities, a large number of important decoction pieces accumulate, resulting in less space between the decoction pieces and making it impossible to thoroughly clean debris and impurities. This requires secondary or multiple cleaning processes, which affects work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a traditional Chinese medicine decoction piece air separator, comprising an air separator box, a discharge port on one side of the air separator box, a connecting cover fixedly connected to the upper surface of the air separator box, a storage hopper fixedly connected to the upper surface of the connecting cover, a sliding groove on one side of the connecting cover, an adjusting plate slidably connected within the sliding groove, a connecting plate fixedly connected to one side of the adjusting plate, connecting blocks fixedly connected to both sides of the connecting plate, the connecting blocks slidably connected to the air separator box, an electric telescopic column fixedly connected to one side of the connecting blocks, a fixing block fixedly connected to the outer wall of the electric telescopic column, the fixing block fixedly connected to the air separator box, a collection box on one side of the air separator box, conveying pipes fixedly connected to both sides of the collection box, the conveying pipes communicating with the air separator box, an air outlet groove on the upper surface of the collection box, a filter screen provided at the air outlet groove, the filter screen fixedly connected to the collection box, a fan fixedly connected to the upper surface of the collection box, and a collection box movably connected to one side of the collection box.
