the outside of the second housing 2, when the material reaches the material receiving port 311 and reaches the inside of the extrusion outer pipe 312, then the extrusion motor 313 drives the spiral vane 314 to rotate, the water on the spiral vane 314 is filtered, the filtered water reaches the extrusion outer pipe 312 through the internal water filtering cylinder 315, then is discharged through the flow guide pipe 318 on the extrusion outer pipe 312, the material after the water filtering reaches the drying pipe 317, the material is discharged after the drying is dried, the material reaches the drying pipe 317, the material is discharged after the drying, the material reaches the spiral extrusion dehydration structure 31, the material is dehydrated, the second housing 2 is positioned at the bottom of the second housing 32, and the second housing 32 is fixed at the position of the outside of the spiral dehydration structure, and the material is located at the outside of the second housing 2.
The position that is located the aggregate plate 32 below on the inner wall of second shell 2 is fixed with crushing case structure 33, crushing case structure 33 smashes case structure 33 and includes crushing box 331, smash motor 332 and crushing puddler 333, crushing box 331 is fixed in the inside of second shell 2, smash motor 332 fixes the bottom at crushing box 331, smash puddler 333 rotates the inside at crushing box 331, smash the output shaft of motor 332 and the bottom mounting of crushing puddler 333, the material after the stoving is harder, need smash through this crushing case structure 33, smash the material that falls through smashing motor 332 rotation drive crushing puddler 333 high-speed rotation, make it be called powder and smash the discharge gate position ejection of compact through the bottom, the material sediment reaches crushing case structure 33 and smashes, the material sediment after smashing is through smashing the discharge gate position ejection of compact of crushing case structure 33 bottom, thereby accomplish the purpose of edulcoration purification, the operation can rise inside temperature under high pressure like this, make hardness great and wrap up with the desulfurization gypsum particle of impurity dilute, the material after the dilution is filtered again and can reach the edulcoration effect that is better, and after the edulcoration and the stoving gypsum can directly obtain the form through the improvement of the powder and directly obtains the form after the stoving gypsum.
