[0002] A sedimentation thickener is a device used for solid-liquid separation and concentration, and is commonly used in mining, chemical industry, environmental protection and other fields. Its working principle is to use gravity to make solid particles settle in liquid, thereby achieving solid-liquid separation and concentration. In the sedimentation thickener, the liquid mixture undergoes a series of treatment processes, including mixing, precipitation, filtration and separation, and finally obtains concentrated liquid and solid materials. Lithium is a light metal element with high specific energy and specific power, and is widely used in batteries, alloys, pharmaceuticals and other fields.

Therefore, the utility model provides a high-efficiency sedimentation thickener to solve the problems raised in the above-mentioned background technology. Utility Model Content
