The separating screw decanter centrifuges having double acceleration discharging cover installed in screw conveyer

摘要

PURPOSE: A screw decanter centrifuge having a double acceleration discharge cover included on a screw conveyor is provided to improve settleability of sludge by preventing vortex of the sludge due to a direct discharge when the sludge arrives in a boundary point of a compressive dehydration unit. CONSTITUTION: A screw decanter centrifuge having a double acceleration discharge cover included on a screw conveyor comprises: one or more outlets(516) which passes through a screw inner driving conveyor(512) after making the flow of sludge supplied from a sludge input tube(501) constant; a conductive disc(1) which is included on the front surface of the moving direction of sludge; and a dual acceleration discharge cover(2) which is formed along the circumference of the screw inner driving conveyor and is apart from an outlet entrance.
