The reducing spiral auger 17 passes through the discharge port 4, and a truncated cone-shaped shaft end top block 13 which can move along the axial direction of the reducing spiral auger 17 is provided at the discharge port 4. A spring baffle 12 is fixedly connected to the outer side of the shaft end top block 13. The shaft end of the reducing spiral auger 17 is connected to a trapezoidal nut 10 through a spiral screwing. A compression spring 9 located between the spring baffle 12 and the trapezoidal nut 10 is sleeved on the reducing spiral auger 17. A drain port 18 is connected to the bottom side of the lower sheet metal 7. Spray pipes 3 are provided on both sides of the upper sheet metal 2. The extrusion net 16 is cleaned by the spray pipes 3. The output shaft of the driving motor 5 is transmission-connected to one end of the reducing spiral auger 17.

[0026] According to the requirement of the water content of the homogeneous organic material, the trapezoidal nut 10 is twisted to adjust the elastic force of the compression spring 9, adjust the pressure value of the shaft end top block 13, and then the drive motor 5 is started to drive the variable diameter spiral auger 17 to rotate slowly. After that, the crushed homogeneous organic material is put into the extrusion guide barrel 15 through the feed port 1, and the variable diameter spiral auger 17 is driven by the drive motor 5 to rotate. The water-containing material is compressed in volume under the action of the variable diameter spiral, so that the water in the liquid is quickly separated and removed through the filter hole and discharged through the drain port 18, and the water content of the solids gradually decreases under the action of continuous compression, and finally squeezes the shaft end top block 13 under the conveying action of the spiral and is discharged from the discharge port 4.

[0030] Working principle: When in use, according to the requirement of moisture content of homogeneous organic materials, twist the trapezoidal nut 10, adjust the elastic force of the compression spring 9, adjust the pressure value of the shaft end top block 13, and then start the drive motor 5 to drive the variable diameter spiral auger 17 to rotate slowly. After that, the crushed homogeneous organic materials are put into the extrusion guide barrel 15 through the feed port 1, and the variable diameter spiral auger 17 is driven by the drive motor 5 to rotate. The water-containing material produces volume compression under the action of the variable diameter spiral, so that the water in the liquid is quickly separated and removed through the filter holes and discharged through the drain port 18, and the water content of the solids gradually decreases under the action of continuous compression. Finally, under the conveying action of the spiral, the shaft end top block 13 is squeezed open and discharged from the discharge port 4. It is suitable for organic wet garbage that has been crushed and processed for solid-liquid separation.
