Abstract

The invention discloses a device for removing impurities and extracting NdFeB waste, which includes a reaction pot, a filter box, an extraction tank, a saponification mixing tank, a stripping box and a collection box. A first feeding box is arranged on one side of the reaction pot. The inside of the extraction tank is provided with a material distributing mechanism, a stirring mechanism and a pre-stirring plate. One side of the extraction tank is provided with a secondary separation tank. One side is provided with a second outlet pipe, the bottom of the extraction tank is provided with a tee pipe, the inside of the extraction tank and the secondary separation tank are provided with turbidity sensors, and the top of the saponification mixing tank is provided with a second feeding box and The third feeding box. In the present invention, the filtrate is evenly sprayed on the multi-layer distribution board through the multi-layer spray plate and the atomizing nozzle to accelerate the saponification reaction, and the mixed liquid is discharged to the inside of the pre-stirring plate for preliminary stirring and mixing, and then enters the extraction tank for re-mixing to speed up the mixing. Uniformity and speed with increased extraction.

Description

technical field [0001] The invention relates to the field of NdFeB waste material removal and extraction, in particular to a NdFeB waste material removal and extraction device. Background technique [0002] When removing impurities and extracting existing NdFeB waste, the quality of the extracted rare earth elements is often reduced due to uneven mixing of materials, resulting in waste of materials, or the need for too long stirring time, resulting in low processing efficiency. [0003] Therefore, it is necessary to invent a NdFeB waste impurity removal and extraction device to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a kind of NdFeB waste impurity removal and extraction device, the filtrate is evenly sprayed on the multi-layer distribution board through the multi-layer spray plate and the atomizing nozzle, and the mixed liquid is discharged to the top distribution board, so that the filtrate Mix evenly...
