FDLJ Screw Type Sludge Dehydrator

FDLJ SCREW TYPE SLUDGE DEHYDRATOR

FDLJ screw type sludge dehydrator is suitable for the solid and liquid separation of the sewage treatment plant, food, pharmaceutical, beverage, chemical, petrochemical, paper, leather, metallurgy, printing and dyeing, livestock, coal chemical, mineral processing, acid washing and electroplating. It is mostly used in sewage treatment process (water content 95-97%) or low concentration sewage mud (water content 99.7%-97%) was further dehydrated to make mud cake (water content 30-85%).  

     The main body of the dehydrator mainly consists of the concentrated and dehydrating parts. When the concentrated sludge enters the main body of the dehydrator, the relative movement of the fixed ring and moving ring is used to make the filtrate expelled rapidly through the laminated gap, and the sludge is rapidly condensed, and the sludge goes to the dehydrating part. When the sludge enters the dehydrating part, the space in the filter cavity is continuously reduced. The internal pressure of the sludge is continuously enhanced, and the pressure regulating function of the pressure regulating plate is added to achieve high efficiency dehydration, and the sludge is continuously discharged out of the machine.
