A sorting and screening device for rare earth oxides

Abstract

The invention relates to a screening device, in particular to a classifying and screening device for rare earth oxides, and aims to provide the classifying and screening device which is used for the rare earth oxides and is high in screening speed, uniform in screening and capable of consuming little manpower. The device comprises bases, a working box, an impact device, a discharging device, rollers, a filter net, a connecting rod and the like; the bases are symmetrically arranged on the left side and the right side of the bottom of the working box; an inlet is formed in the top wall of the working box; an outlet is formed in the back wall of the working box; the impact device is arranged at the inner bottom of the working box; sliding rails are symmetrically arranged on the left side and the right side inside the working box; and the sliding blocks are arranged on the sliding rails. The device realizes the effects of being high in screening speed, uniform in screening and capable of consuming little manpower; and with the device, the rare earth oxides in a first tank are impacted and screened by the aid of the impact device.

Description

Technical field [0001] The invention relates to a screening device, in particular to a rare earth oxide classification screening device. Background technique [0002] Rare earth oxides refer to 15 lanthanide oxides with atomic numbers 57 to 71 in the periodic table, and 17 oxides of scandium and yttrium, which are chemically similar to lanthanides. Rare earth elements have been widely used in petroleum, chemical industry, metallurgy, textiles, ceramics, glass, permanent magnetic materials and other fields. With the advancement of science and technology and continuous breakthroughs in application technology, the value of rare earth oxides will become greater and greater. In order to facilitate the use of rare earth oxides, rare earths need to be crushed during production and processing. After the crushing treatment, the particle sizes of the rare earth oxides are different. At this time, in order to better use the rare earth oxides, the large particles of rare earth oxides need t...
