[0002] Dried phosphogypsum offers the benefits of improved product performance, reduced environmental pollution, increased economic benefits, and easier storage and transportation.

The purpose of the grinding block 10 is to grind the phosphogypsum.

[0033] The front end of the drying tube 1 is fixedly connected to a hot air blower 11, which is designed here to heat air to evaporate the moisture in the phosphogypsum. The bottom end of the drying tube 1 is fixedly connected to a motor 3 12, which is designed here to serve as a power driving source for the stirring action. The driving end of the motor 3 12 is fixedly connected to an auger 13, which is designed here to turn and propel the phosphogypsum to ensure that the material is heated evenly.

The support columns 14 are designed here to provide firm support for the entire device to ensure its stability during operation.

[0034] Reference Figure 1 , Figure 4 The screening assembly includes a mesh screen 15, the top of which is slidably connected to the bottom of the drying tube 1. The mesh screen 15 is designed here to screen the dried phosphogypsum. The purpose of the mesh screen 15 is to screen the phosphogypsum into different sizes. The outside of the mesh screen 15 is fixedly connected to a round shell 16. The round shell 16 is designed here to protect the mesh screen 15 and enhance the stability of the structure. The outside of the round shell 16 is fixedly connected to a plurality of sliding blocks 17. The sliding blocks 17 are designed here to allow the round shell 16 to move. The outsides of the plurality of sliding blocks 17 are slidably connected to the same support frame 18. The support frame 18 is designed here to provide a stable support platform for the screening assembly. The bottom of the turntable 20 is rotatably connected to the top of the support frame 18.

[0035] The top of the support frame 18 is fixedly connected to a motor 4 19, which is designed here as a power source to drive the turntable 20 to rotate. The driving end of the motor 4 19 is fixedly connected to the turntable 20, which is designed here to drive the round shell 16 to slide. The top of the turntable 20 is fixedly connected to a rotating shaft 21, which is designed here to transmit power. The outer portion of the rotating shaft 21 is rotatably connected to a connecting shaft 22, which is designed here to pull the round shell 16 to slide as power transmission. The outer portion of the connecting shaft 22 is fixedly connected to the outside of the round shell 16. The bottom of the support frame 18 is slidably connected to a collecting box 23, which is designed here to collect and process the screened phosphogypsum.

[0036] Working principle: When it is necessary to grind large pieces of phosphogypsum into powder or small pieces for more thorough drying, pour the phosphogypsum from the top of the wheel cover 5, and the motor 13 drives the gear 4 to rotate, driving the wheel cover 5 threadedly connected to the feed block 2 to rise, thereby increasing the distance between the bottom of the wheel cover 5 and the grinding block 10, thereby controlling the amount and size of phosphogypsum that can enter the feed block 2. This step is crucial for the subsequent drying process, because too large or too small pieces of material may affect the drying efficiency and product quality. Start the motor 2 6, and the drive end drives the shaft gear 1 7 to rotate, thereby The meshing shaft teeth 2 9 are driven to rotate. During this process, the phosphogypsum is gradually reduced to the required particle size, thereby increasing its surface area. The shaft teeth 2 9 drive the grinding block 10 on the top to rotate, and squeeze the phosphogypsum and the feed block 2 inside the feed block 2, thereby reducing the phosphogypsum. The surface area of ​​the phosphogypsum after preliminary crushing is significantly increased, which allows the hot air to contact it more fully, thereby accelerating the evaporation rate of moisture. At the same time, since the phosphogypsum has been broken into smaller particles, its internal moisture is more easily carried away by the hot air, further improving the drying efficiency.

[0037] When it is necessary to screen out the dry phosphogypsum that has been ground and stirred into powder, the phosphogypsum flows out from the bottom of the drying tube 1 and falls on the top of the mesh 15, thereby ensuring that only phosphogypsum that meets the specific particle size requirements can pass through. When inside the circular shell 16, the driving end of the starting motor 19 drives the turntable 20 to rotate. The rotation of the turntable 20 is the power source of the entire screening action, so that the rotating shaft 21 drives the connecting shaft 22 to swing. When connected to the connecting shaft 22, the circular shell 16 is subjected to the tension from the connecting shaft 22. The multiple sliding blocks 17 on the outside fix the connecting shaft 22 while continuously sliding inside the support frame 18. As the circular shell 16 shakes, the sliding blocks 17 also slide inside the support frame 18, providing additional power and stability for the shaking of the circular shell 16, causing the circular shell 16 to shake, and the powdered phosphogypsum is screened out through the screening of the mesh 15 and flows into the collection box 23 for collection.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
