Neodymium iron boron waste material screening device and using method

Abstract

The invention discloses a neodymium iron boron waste material screening device, and relates to the technical field of neodymium iron boron processing. The screening device comprises a base body, a placing part, a protective cover, a rotating part and a control part, wherein a containing space is formed in the base body; the placing part is connected with the base body, and the placing part comprises a connecting body arranged inside the base body; the protective cover is arranged above the base body, and the protective cover and the placing part have same axis; the rotating part is arranged inside the placing part, and the rotating part comprises a rotating shell arranged inside the placing part; and the control part is arranged on one side of the placing part, and the control part comprises a driven shaft, wherein the driven shaft is fixedly connected with the connecting body, the driven shaft penetrates through the rotating part, and the driven shaft and the rotating part have same axis. According to the neodymium iron boron waste material screening device, when being subjected to recovery treatment, a neodymium iron boron waste material is cleaned and screened first, so that theeffect of the treatment process is ensured; and meanwhile, impurities in the cleaned neodymium iron boron waste material are reduced, so that the workload during recovery treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of NdFeB processing, in particular to an NdFeB waste screening device and a use method. Background technique [0002] NdFeB waste is the main type of rare earth permanent magnet waste at present. NdFeB waste is generally powdery, granular, massive, muddy, some with high water content, some with less water content, and some soaked in liquid Among them, some samples showed different colors and odors, and most of the samples had low content of volatile components. The recovery of NdFeB waste is more convenient than the direct crushing of ore to obtain rare earth resources, because the content of rare earth in NdFeB waste is much higher than that of ore. [0003] Moreover, the waste generated after the processing of NdFeB products is probably produced in the following five situations: (1) The loss of various single raw materials such as metallic neodymium, pure iron, ferroboron, metal Dysprosium etc. (2) Seve...

Problems solved by technology

[0005] The purpose of the present invention is to provide a screening device for NdFeB waste, which is used to solve the problem that the NdFeB waste in the prior art cannot be completely separated from impurities during cleaning, and the separated impurities and waste cannot be separated quickly, resulting in Impurities will also stick to the waste, and the cleaning effect is poor
