本发明公开了一种基于奥氏体冷相变的金属碎屑运输分类车,包括滚筒碾压相变式冷轧金相组织磁化装置、柔性循环式钢碎屑磁吸刮板分拣集中装置、手推式运输行进装置、动态型自动分层式离心分拣装置和周期式碎料下料主动控制调节装置。本发明属于金属碎屑分类领域,具体是指一种基于奥氏体冷相变的金属碎屑运输分类车;本发明通过强力碾压使钢碎屑中的呈弱磁性或者无磁性的奥氏体组织转变为呈磁性的马氏体组织,为了避免碾压过程中金属碎屑相互交缠,在挤压之前,对金属碎屑进行破碎处理,配合基于密度的动态型自动分层式离心分拣装置,有效解决了目前的金属碎屑回收过程时间长、钢碎屑用磁吸法无法完全分拣以及分拣过程中碎屑容易相互交缠的问题。

    The invention discloses a metal scrap transporting and classifying vehicle based on austenite cold phase change. The metal scrap transporting and classifying vehicle comprises a roller rolling phase change type cold rolling metallographic structure magnetizing device, a flexible circulating type steel scrap magnetic suction scraper sorting and concentrating device, a hand-push type transporting and advancing device, a dynamic automatic layered centrifugal sorting device and a periodic crushed material discharging active control and adjustment device. The invention belongs to the field of metal scrap classification, and particularly relates to the metal scrap transporting and classifying vehicle based on austenite cold phase change. According to the metal scrap transporting and classifying vehicle based on austenite cold phase change, weak magnetic or non-magnetic austenite structures in the steel scraps are converted into magnetic martensite structures through powerful rolling, in order to avoid mutual intertwining of the metal scraps in the rolling process, the metal scraps are subjected to crushing treatment before extrusion, and through cooperation with the dynamic automatic layered centrifugal sorting device based on density, the problems that the time of the current metal scrap recycling process is long, the steel scraps cannot be completely sorted through a magnetic attraction method, and the scraps are prone to intertwining in the sorting process are effectively solved.
