A rare earth particle separation system

Abstract

The invention belongs to the technical field of separation devices and particularly relates to a rare earth particle separation system. The system comprises a box, a water inlet pipe, a drainage pipe,a drying box and a sieving module, wherein the sieving module comprises an elastic sieve, a rotating roll, a pull rope, a guide roll, a swing rod and a first scraping plate; one end of the elastic sieve is fixedly connected with the inner wall of the box, the other end of the elastic sieve is fixedly connected to the outer ring of the rotating roll, the rotating roll rotates forwards and backwards cyclically under the drive of a motor, one end of the pull rope is fixedly connected to the outer ring of the rotating roll, the other end of the pull rope is fixedly connected to one side of the swing rod after being guided by the guide roll, the upper end of the swing rod is hinged to the bottom of a top plate of the box, a sliding chute is formed in the lower end of the swing rod, and the first scraping plate is glidingly mounted in the sliding chute. The rotating roll of the sieving module rotates, rare earth particles in troughs of the elastic sieve are turned out and fall into a collecting box after being dried by a heating plate, separation and recovery of the rare earth particles are completed, and the recovery efficiency of the rare earth particles can be improved.

Description

technical field [0001] The invention belongs to the technical field of separation devices, in particular to a rare earth particle separation system. Background technique [0002] Rare earths are known as "industrial vitamins". Now it has become an extremely important strategic resource. Rare earth element oxides refer to oxides of 15 lanthanide elements with atomic numbers from 57 to 71 in the periodic table of elements, and oxides of scandium and yttrium, a total of 17 elements whose chemical properties are similar to lanthanide elements. Rare earth elements have been widely used in petroleum, chemical industry, 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 the rare earth treatment process, precipitation wastewater and leaching wastewater will be produced, and some rare earth p...

Problems solved by technology

[0005] This technical solution separates the rare earth particles in the waste water by vibrating the filter screen, and the rare earth particles attached to the filter screen are not easy to recover. This solution does not have a device for centralized recovery of the separated rare earth particles, which makes the separation and recovery efficiency of this solution low.
