Description

Impurity separator for rare earth permanent magnet material for civil engineering
Technical Field
The invention relates to the technical field of impurity separation equipment for rare earth permanent magnet materials, in particular to an impurity separator for a rare earth permanent magnet material for civil engineering.
Background
The civil engineering refers to engineering entities for surveying, planning, designing, constructing, installing and maintaining various technical works and the like of newly-built, reconstructed or expanded buildings, structures, related supporting facilities and the like of various projects except house buildings.
The rare earth engineering is a direction and branch of civil engineering, wherein the rare earth is a permanent magnetic material, which refers to a material capable of keeping constant magnetism once magnetized. In practice, the permanent magnet material works in the second quadrant demagnetization part of the hysteresis loop after deep magnetic saturation and magnetization. The commonly used permanent magnet materials are classified into an aluminum-nickel-cobalt permanent magnet alloy, an iron-chromium-cobalt permanent magnet alloy, a permanent magnetic ferrite, a rare earth permanent magnet material, a composite permanent magnet material and the like. Wherein, the rare earth permanent magnetic material is a permanent magnetic material which accounts for a relatively large part in the market.
The rare-earth permanent-magnet material is neodymium-iron-boron Nd2Fe14B, the method is divided into the following three types according to different production processes:
(1) sintered NdFeB (Sintered NdFeB) -the Sintered NdFeB permanent magnet is ground by airflow
The powder is smelted, the coercive force value is very high, the magnetic performance is extremely high, and the maximum magnetic energy product (BHmax) of the powder is more than 10 times higher than that of Ferrite (Ferrite). The mechanical property of the cutting tool is quite good, and the cutting tool can be used for cutting and processing different shapes and drilled holes. The maximum working temperature of the high-performance product can reach 200 ℃. Because of its substance content, which easily leads to staining, the surface has to be subjected to different coatings according to different requirements. (such as zinc plating, nickel plating, environment-friendly zinc plating, environment-friendly nickel plating, nickel copper nickel plating, environment-friendly nickel copper nickel plating, etc.). Very hard and brittle, with high demagnetization resistance, high cost/performance ratio, not suitable for high operating temperatures (>200 ℃).
(2) Bonded neodymium iron boron (Bonded NdFeB) -Bonded neodymium iron boron is a composite neodymium iron boron permanent magnet prepared by uniformly mixing neodymium iron boron powder with binders such as resin, plastic or low-melting-point metal and the like and then using methods such as compression, extrusion or injection molding and the like. The product is formed in one step, does not need secondary processing and can be directly made into various complex shapes. The bonded neodymium iron boron has magnetism in all directions and can be processed into a neodymium iron boron compression mold and an injection mold. High precision, excellent magnetic performance, good corrosion resistance and good temperature stability.
(3) Injection-molded neodymium-iron-boron (Zhusu NdFeB), which has extremely high precision and is easy to be made into thin-wall rings or thin magnets with complicated anisotropic shapes.
Although the rare earth permanent magnet material has the most excellent magnetic performance, the rare earth permanent magnet material has serious weaknesses, one of which is that the corrosion resistance is poor, the electrochemical corrosion potential of the Nd-rich phase of the rare earth permanent magnet is extremely low, the rare earth permanent magnet is easy to oxidize and absorb hydrogen for hydrolysis, and therefore, the rare earth permanent magnet can be rapidly degraded under certain environment and loses the magnetic performance. If the rare earth permanent magnet materials degraded by corrosion are directly discarded, the waste of rare earth resources is caused, so that a method for regenerating a high-performance permanent magnet by using the waste rare earth permanent magnet materials is developed in succession.
However, in the process of recovering the waste rare earth permanent magnet material, impurity removal is an important part, and if manual picking is adopted, the waste rare earth permanent magnet material still has certain magnetism more or less, so that the impurities are difficult to strip, and the recovery efficiency is not high, so that the impurity separator for the rare earth permanent magnet material for civil engineering needs to be designed, and the impurity removal efficiency is improved.
