Meal residue separating system

The invention discloses a meal residue separating system which communicates with an outlet of a centrifugal pump. The meal residue separating system consists of a housing, a filter assembly, a liquiddischarge tube, a sealing pad and a plugging mechanism, wherein the filter assembly consists of a primary filter element, a first fixing ring, a second fixing ring and a fine filter element which is wound at the outer side of the primary filter element; buckling holes are formed in the housing wall at the outlet end of the housing; the sealing pad sleeves the outside of the first fixing ring and the outside of the second fixing ring; and the plugging mechanism consists of a supporting base, locking rods, jacking rods, a supporting rod and an extruding plug which is positioned at the front endof the supporting rod for plugging the outlet of the primary filter element. The meal residue separating system is simple in structure, can be used for highly dewatering meal residue waste quickly, shortens the processing peri
