Rare earth macadam screening device for recovering rare earth wastes

Abstract

The invention relates to a rare earth macadam screening device and particularly relates to a rare earth macadam screening device for recovering rare earth wastes. The technical problem to be solved by the invention is to provide a rare earth macadam screening device for recovering rare earth wastes, and the rare earth macadam screening device is good in screening effect, high in screening speed, capable of adjusting the charging flow of a charging hopper, high in utilization ratio and capable of reducing economic loss and saving resources. In order to solve the technical problem, the invention provides such a rare earth macadam screening device for recovering rare earth wastes; the rare earth macadam screening device comprises a bottom plate, a screening barrel, a side plate, a vertical moving device, a first supporting rod, a first charging hopper, a box door, a first connecting rod, a slide block, a second connecting rod, a U-shaped magnet and the like; and the middle of the top of the bottom plate is provided with the screening barrel. According to the rare earth macadam screening device for recovering rare earth wastes, provided by the invention, the rare earth wastes in an iron screening plate are screened by rotating the iron screening plate.

Description

technical field [0001] The invention relates to a rare earth crushed stone screening device, in particular to a rare earth screening device for recycling rare earth crushed stone waste. Background technique [0002] Rare earths have the reputation of "industrial vitamins". Now it has become an extremely important strategic resource. Rare earth element oxides refer to 15 lanthanide oxides with atomic numbers from 57 to 71 in the periodic table, as well as 17 oxides of scandium and yttrium with similar chemical properties to lanthanides. Rare earth elements have been widely used in petroleum, chemical, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields. With the advancement of science and technology and continuous breakthroughs in application technology, the value of rare earth oxides will increase. [0003] In recent years, due to the over-exploitation of rare earth resources, it has not only caused great waste of resources, but also caused se...
