Description

Technical Field

[0001] The utility model relates to the technical field of phosphogypsum purification treatment, in particular to a solid mixture mixing and settling device with continuous discharging. Background Art

[0002] The main component of the solid mixture is calcium sulfate, and other components include attached water, a small amount of organic matter, soluble potassium and sodium salts such as phosphate, fluoride, and chlorosulfate, as well as crystalline phosphorus, aluminum and magnesium. Add water to the mixture and stir and mix. After standing for a period of time, natural stratification will occur. The top layer is a black oil phase foam layer, a transparent clear solvent layer, a black mud phase layer, a gray mud phase layer, and the bottom layer is a gray solid phase layer. The principle is that the solid particles have different specific gravities in water and different sedimentation rates. Molecules with higher specific gravity will quickly settle to the bottom, and molecules with lighter specific gravity will settle more slowly.

[0003] After searching the existing public patent number: CN202222317260.4, the name of the public patent is: a solid mixture mixing and settling device with continuous discharge, a liquid spray ring is provided inside the settling tank, and a plurality of liquid spray nozzles are provided on the liquid spray ring, and the nozzles are arranged in an upward direction. A pressure liquid inlet is also provided on one side of the settling tank, and the pressure liquid inlet is connected to the liquid spray ring. The conical discharge port at the bottom of the settling tank is connected to the screw conveyor. The settling tank can be used in series to continuously process solid mixtures in batches. The purity of calcium sulfate dihydrate in the solid mixture is greatly improved, and the impurity content reaches the industrial gypsum standard, which can be widely used in the fields of building materials, cement retarders, etc.

[0004] However, the above device has poor liquid mixing effect during use. During the sedimentation process, most of the impurities are mixed in the solid phase layer, resulting in more impurities in the solid phase layer at the bottom, high cost of subsequent purification, and low purification efficiency and high economic cost in the industrial process.
