[0028] The operator pours the phosphogypsum into the storage tank 2. After the addition is completed, the heating plate 15 can be driven to generate heat, and then the heat generated by the heating plate 15 will pass through the storage tank 2 and the gauze 3 and contact the surface of the phosphogypsum, thereby dehydrating the phosphogypsum. During the dehydration process, the motor 13 can be driven to rotate the transmission wheel 15, because the transmission wheel 15 and the transmission wheel 2 6 are connected by the transmission belt 7, and then when the transmission wheel 15 rotates, the transmission belt 7 will drive the transmission wheel 2 6 to rotate, and then the transmission wheel 2 6 will drive the vertical rod 10 to rotate, and then the vertical rod 10 will drive the gear 11 to rotate, because the gear 11 and the gear ring 12 rotate, and then when the gear 11 rotates, it will drive the gear ring 12 to rotate inside the dehydration box body 1, and then the gear ring 12 will drive the connecting plate 14 and the heating plate 15 to rotate. Through the rotation of the heating plate 15, the phosphogypsum can be evenly dehydrated.
[0029] During the rotation of the transmission wheel 5, the transmission wheel 5 will drive the rotating rod 8 to rotate, and then the rotating rod 8 will drive the stirring paddle 9 to rotate.

[0035] Through the design of the annular groove 22 and the supporting ring 23, when the vertical rod 10 rotates, the supporting ring 23 will rotate inside the annular groove 22, thereby supporting and limiting the vertical rod 10 to avoid position displacement when the vertical rod 10 rotates; through the design of the discharge pipe 24 and the valve 25, after the dehydration of the phosphogypsum inside the storage tank 2 is completed, the valve 25 can be opened, and then the dehydrated phosphogypsum will be discharged from the inside of the discharge pipe 24.

After the phosphogypsum is added, the heating plate 15 can be driven to generate heat, thereby dehydrating the phosphogypsum inside the storage tank 2, and then the motor 13 can be driven to rotate the transmission wheel 1 5, and then the transmission wheel 1 5 will drive the transmission wheel 2 6 and the transmission belt 7 to rotate, and then the transmission wheel 2 6 will drive the vertical rod 10 and the gear 1 1 rotates, and then the gear 11 drives the gear ring 12 to rotate, and then the gear ring 12 drives the connecting plate 14 and the heating plate 15 to rotate. The rotation of the heating plate 15 can make the phosphogypsum evenly dehydrated, and when the transmission wheel 5 rotates, the rotating rod 8 and the stirring paddle 9 rotate accordingly, and then the stirring paddle 9 stirs the phosphogypsum inside the storage tank 2, thereby increasing the dehydration effect of the phosphogypsum. After the dehydration is completed, the valve 25 can be opened, and then the phosphogypsum inside the storage tank 2 will be discharged from the inside of the discharge pipe 24, and finally the operation process is completed.
