Abstract
Description
Technical Field
[0001] The utility model relates to a device for accurately adding phosphogypsum modified materials. Background Art
[0002] Phosphogypsum refers to the solid waste residue produced when phosphate ore is treated with sulfuric acid in phosphoric acid production. Its main component is calcium sulfate, and its pH value is between 2.5 and 4, which is weakly acidic. When used as a recycled building material, the pH value of phosphogypsum needs to be adjusted to above 6.0. Currently, quicklime is used as a modifier to adjust the pH value of phosphogypsum. The existing modified material is added during the transportation of phosphogypsum. The amount of modified material added is proportional to the speed of the conveyor belt for transporting phosphogypsum. However, the transportation amount of phosphogypsum is sometimes more and sometimes less and not constant, so the proportion of modified material added cannot be accurately controlled.
