Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine processing equipment, in particular to a dust removal device and system for traditional Chinese medicine pieces. Background Art

[0002] Decoction pieces refer to Chinese medicines that are processed according to needs and are used for prescription, or can be directly used in clinical Chinese medicine. Chinese medicine decoction pieces are the essence of Chinese medicine. The medicinal properties and effects of medicinal materials will change after different processing methods, which is the characteristic and advantage of Chinese medicine. During the processing of Chinese medicine decoction pieces, in order to ensure the cleanliness of important decoction pieces, the Chinese medicine decoction pieces need to be pre-treated and dusted. However, most of the current pre-treatment dust removal devices have poor dust removal effect and low dust removal efficiency. Therefore, it is very necessary to provide a Chinese medicine decoction piece dust removal device with simple structure, good dust removal effect and high dust removal efficiency.

[0003] After searching, the patent document with application publication number CN112207074A discloses a dust removal device for Chinese herbal medicine slices. Although the device can process floating dust during use, it cannot process unpleasant gases, and the dust falling in the dust removal device body needs to be cleaned manually, which is troublesome. Also, the Chinese patent with authorization announcement number CN216397189U discloses a dust removal device for Chinese herbal medicine slices, which can effectively reduce unpleasant gases through a freshening mechanism, and does not need to manually clean dust through a cleaning mechanism, which is more time-saving and labor-saving.
