The invention relates to an extraction device, in particular to a flotation extraction device for rare earth. The invention provides a flotation extraction device for rare earth, which is low in manufacturing cost, simple and understandable to operate and applicable to small rare earth processing plants. The flotation extraction device for rare earth comprises a reaction tank and a first fixing sleeve, whererein the first fixing sleeve is arranged on the reaction tank; a rotating shaft which is rotatably arranged on the reaction tank, wherein the first fixing sleeve is rotatably connected with the rotating shaft, and first stirring rods are uniformly arranged on the rotating shaft; a defoaming mechanism which is arranged on the reaction tank; and a flotation mechanism which is arranged on the reaction tank. A connecting rod moves backwards to drive a defoaming plate to move backwards, so that a sliding sleeve is driven to move backwards, the defoaming plate moves backwards to scrape a foam product on the surface of rare earth slurry out of the reaction tank, and the defoaming effect is achieved.
Description
technical field [0001] The invention relates to an extracting device, in particular to a device for extracting rare earth by flotation. Background technique [0002] Rare earth is the abbreviation of a group of metals, which are widely used in many industries such as metallurgy, electronics and petrochemicals. Rare earths are industrial vitamins. Rare earths are widely used in civil and military applications. An indispensable raw material in the industry, the basic principle of flotation is to use the lattice defects on the crystal surface, and the outward hydrophobic end is partially inserted into the air bubbles, so that the air bubbles may take the specified mineral powder away during the flotation process , to achieve the purpose of beneficiation, in the existing rare earth flotation extraction device, the manufacturing cost is relatively high, and it is not suitable for small rare earth processing plants. [0003] Therefore, according to the above-mentioned situation, ...
