The invention discloses a vacuum suction-type screw-
extrusion solid-liquid
separation system. The vacuum suction-type screw-
extrusion solid-liquid
separation system comprises a screw extruding mechanism, a driving mechanism, a sealing box body, a vacuumizing
machine, an airtight water tank and a continuous liquid discharging mechanism, wherein the screw extruding mechanism is connected with a
continuous feeding mechanism and a continuous
solid discharging mechanism, the driving mechanism is used for providing the rotation power, the screw extruding mechanism is sealed inside the sealing box body, the vacuumizing
machine is communicated with the sealing box body through a pipeline and used for providing vacuum
suction force to the vacuum suction-type screw-
extrusion solid-liquid
separation system, the airtight water tank is connected onto a pipeline between the sealing box body and the vacuumizing
machine and used for collecting the liquid discharged from the screw extruding mechanism, and the continuous liquid discharging mechanism is arranged on the airtight water tank. By utilizing the integral vacuum suction principle, the vacuumizing machine which is arranged at the rear end is used for providing the vacuum
suction force to the entire internal space, the reliability is high, the flow is optimized, the continuous suction function, the continuous solid /
slag discharging function and the continuous liquid discharging function can be realized, the
sewage waste treatment time is effectively saved, and the
time cost and the labor cost can be greatly saved.
