THE SEPARATING SCREW DECANTER CENTRIFUGES HAVING DOUBLE ACCELERATION DISCHARGING COVER INSTALLED IN SCREW CONVEYER

摘要

It include the lid for accelerating to be formed among discharge auger conveyer in dual-stage the present invention relates to one screw-decane Ether type centrifuge, the discharge port that outlet pressure and violent vortex phenomenon of the object far from sludge dewatering unit pass completely through screw conveyor, which is ejected, removes solid and supernatant liquor by a centrifugal force since sludge is by preventing the vortex phenomenon of sludge from improving regeneration rate and precipitating to provide and a screw-decane Ether type centrifuge of water content can be improved directly be discharged, when it reaches pressure dehydration section boundary. ;By being vortexed the configuration of the invention prevented, the inside of 512 flowings of the screw conveyor for the sludge that sludge grout pipe by penetrating 501 in the axial direction is supplied not has a preset flight path and drives sludge by screw conveyor (512) not, the induction disk (1) that there is at least one discharge port 516 formed among the front of moving direction to be formed; Discharge port 516 is separated from each other preset distance, and discharge port 516, to the entrance in path, accelerate-increase and prevent simultaneously in peripheral direction vortex screw conveyor 512 not so that there is the constant direction of flowing by sludge, two form in the circular screw decane Ether type centrifuge that there is the dual-stage formed among discharge cover to accelerate, it is characterised in that screw conveyor is made of Accelerating Removal end pump cover (2).
