Description

Technical Field

[0001] The utility model belongs to the technical field of pulverizers, in particular to a multi-stage pulverizer. Background Art

[0002] Polygonatum sibiricum is a perennial herb, which is mainly used as a medicinal material or a raw material for pharmaceutical preparations. When Polygonatum sibiricum is used as a medicinal material or a raw material for pharmaceutical preparations, it needs to be processed.

[0003] The processing of polygonatum is a process involving multiple steps, mainly including washing, drying, steaming, frying or crushing. When crushing polygonatum, the polygonatum is first washed and dried, and then cut into suitable sizes, and the cut polygonatum pieces are put into a crusher for crushing. In the existing polygonatum crushing technology, when a multi-stage crusher is used to crush polygonatum, the upper-stage crushing component crushes the polygonatum, and then the polygonatum powder is filtered through a filter plate and enters the next-stage crushing component. The polygonatum powder accumulates on the filter plate, causing the filter plate to be blocked, affecting the speed of the polygonatum crushing process.

[0004] To this end, the utility model provides a multi-stage crusher. Utility Model Content

The polygonatum after initial crushing is sieved by the sieve plate 14, and the polygonatum powder with the required particle size falls on the surface of the guide plate 18 and slides into the next-level crushing mechanism for the next-level crushing. In this step, the polygonatum raw material is crushed in multiple stages through the arrangement of the crushing tool 13, the sieve plate 14, the fixing frame 15, the scraper 16, the first spring 17, and the guide plate 18. During the crushing, the particles on the sieve plate 14 are scraped up to reduce the blockage during the filtering of the polygonatum powder, improve the smoothness of the polygonatum crushing, and increase the speed of the polygonatum crushing.
