Screw extruder for separating liquids from suspension, particularly sludge- or fiber suspension, has casing having radially inner filter and radially outer supporting body, which is made of multiple axially spaced ring segments

摘要

#CMT# #/CMT# The screw extruder has a screw shaft (2) rotating in a cylindrical casing (1), where a suspension is pressed through an annular passage from an inlet opening (4) to an outlet opening (9). The casing has a radially inner filter (5) and a radially outer supporting body (6), which is made of multiple axially spaced ring segments that are connected with each other and are aligned perpendicular to the axis. The connection between the ring segments of respective supporting ring takes place exclusively by connecting elements extending in the peripheral direction of the supporting body. #CMT#USE : #/CMT# Screw extruder for separating liquids from a suspension, particularly sludge- or fiber suspension. #CMT#ADVANTAGE : #/CMT# The casing has a radially inner filter and a radially outer supporting body, which is made of multiple axially spaced ring segments that are connected with each other and are aligned perpendicular to the axis, and hence ensures low manufacturing cost of the screw extruder, as well as ensures high degree of stability associated with minimum weight at the support body. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic cross-sectional views of a screw extruder. 1 : Casing 2 : Screw shaft 4 : Inlet opening 5 : Inner filter 6 : Outer supporting body 9 : Outlet opening.
