[0028] Working principle and usage process of this utility model:

[0029] Calcium magnesium phosphate fertilizer and related reactive compounds are fed into reaction cylinder 1 through feed pipe 4 and inlet 6, respectively. The regulating motor 9 is started, driving the connecting rod 10 to rotate, which in turn drives the connecting ring 12, stirring rod 13, and scraper 14 to rotate synchronously. The stirring rod 13 stirs the calcium magnesium phosphate fertilizer and reactive compounds in reaction cylinder 1 to improve the mixing and reaction efficiency. During stirring, the sieve ring 8 filters the material, causing impurities or solid particles to settle inside the sieve ring 8. Simultaneously, the scraper 14 moves against the sieve ring 8. The surface is cleaned to prevent clogging of the screen holes and ensure screening efficiency. The reacted and filtered liquid, as well as some impurities or particles, permeate and fall through the screen holes and then enter the next stage screen ring 8 with smaller screen hole diameter. The above process is repeated. After three screenings, precipitated particles and impurities accumulate in the screen ring 8. At this time, the sewage pump 16 is started to extract the particles and impurities retained in the screen ring 8 through the sewage pipe 15. The filtered liquid is sent out through the liquid outlet 17, thereby realizing the solid-liquid separation, liquid discharge, sewage discharge and screen cleaning functions of calcium magnesium phosphate fertilizer materials.
