Self-cleaning mechanism and rotary kiln

The self-cleaning mechanism is used for the rotary kiln, the rotary kiln comprises a kiln barrel, the self-cleaning mechanism comprises a scraping piece movably arranged in the kiln barrel, the scraping piece comprises a body and a plurality of scraping claws, the body extends in the axial direction of the kiln barrel, and the scraping claws are arranged on the periphery of the body in a surrounding mode. And the scraping claws are used for scraping material scales on the inner wall of the kiln barrel. According to the technical scheme, the technical problem that the production efficiency of a traditional rotary kiln is low due to the fact that material scaling cleaning is tedious and time-consuming is effectively solved. 本公开涉及一种自清洁机构及回转窑，该自清洁机构用于回转窑，回转窑包括窑简体，自清洁机构包括活动设于窑简体内的刮件，刮件包括本体和多个刮爪，本体沿窑简体的轴向延伸，多个刮爪绕设于本体的外周，刮爪用于刮除窑简体内壁上的物料结垢。本公开技术方案有效解决了传统回转窑由于物料结垢清理繁琐耗时长，导致回转窑生产效率低的技术问题。
