A rare earth particle separation and recovery device

Abstract

The invention belongs to the technical field of separation and recovery devices and particularly relates to a rare earth particle separation and recovery device. The device comprises a casing, a wasteliquid tank, a filter net, a liquid inlet disc, a transition barrel, a discharging door, a gear ring, a rotating arm, a motor, a fixed sleeve, an electric cylinder and a material box. The left end ofthe liquid inlet disc is hinged to the inner wall of the left end of the casing, the right end of the discharging door is hinged to one end of the rotating arm through a spherical surface, the otherend of the rotating arm is fixedly connected with one end of a rotating shaft of the motor, gear teeth on the transition barrel are meshed with gear teeth on the gear ring, so that the transition barrel rotates around own rotating axis while rotating around the hinged position of the left end of the liquid inlet disc, constant rolling of a waste liquid in the filtering net is further guaranteed, the inner surface of the filtering net cannot extrude rare earth particles through constant rolling, the condition that the liquid cannot conveniently penetrate through the filtering net due to blockage of the filtering net by the rare earth particles is further prevented, separation of the liquid and the rare earth particles in the waste liquid is accelerated, and the rare earth separation and recovery efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of separation and recovery devices, in particular to a separation and recovery device for rare earth particles. 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. In the rare earth treatment process, precipitation wastewater and leaching wastewater will be produced,...

Problems solved by technology

[0004] This technical solution can realize the separation and recovery of rare earth particles in wastewater, but in this device, when the flow rate of wastewater flowing through the first filter screen is too large, or after the filter screen has been used for a period of time, the filter screen is blocked by rare earth particles, making the wastewater The separation ability of the liquid in the medium and the rare earth particles decreases, which in turn affects the separation effect and separation efficiency of the wastewater
