In addition to calcium sulfate, there are also incompletely decomposed phosphate rock, residual phosphoric acid, fluoride, acid insoluble matter, organic matter, etc. Among them, the presence of fluorine and organic matter has the greatest impact on the resource utilization of phosphogypsum. The random discharge and accumulation of phosphogypsum has seriously damaged the ecological environment, not only polluting groundwater resources, but also causing waste of land resources. Therefore, various equipment is usually used to treat phosphogypsum, among which water washing and purification equipment is the most common equipment used for phosphogypsum treatment, which is mainly used to wash and purify phosphogypsum; The existing document with publication number CN117225801A discloses a solid waste phosphogypsum water washing and purification equipment, including a water washing box, a rotating plate is arranged outside the water washing box, a motor 2 is fixed to the lower wall of the rotating plate, a fixed plate is arranged outside the rotating plate, a motor 1 is fixed to the right wall of the fixed plate, a storage box is arranged at the upper left of the water washing box, a connecting pipe is arranged inside the water washing box, a movable plate is fixed to the lower end of the connecting pipe, and a through groove is opened on the outer peripheral wall of the lower end of the connecting pipe; However, it still has the following disadvantages in actual use: In the above-mentioned water washing and purification equipment, a storage box is provided on the upper left of the water washing box, and the phosphogypsum inside is washed and purified by the rotation of the water washing box, and the washing liquid is provided to the water washing box through the storage box.
