The spiral structure design with variable diameter and distance is adopted, and different compression ratios are adopted for different slurries. During the slurry movement, the volume gradually shrinks, and the extruded filtrate flows to the filtrate tank through filter plates in different pressing zones. Adjust the pressure of the backpressure device at the discharge end and the speed of the screw shaft to control the slurry concentration and yield. According to different structural design, it can be suitable for the extraction and concentration of black liquid of slurries such as chemical slurry, chemical slurry, waste paper slurry and other slurries.
