摘要: Die vorliegende Erfindung betrifft einen Schneckenextruder (1) zum Extrudieren eines ersten Ausgangsstoffs, aufweisend eine in einem Gehäuse (2) ausgebildete Kavität (8), zumindest eine in der Kavität (8) angeordnete Extruderschnecke, eine an einem vorderen Ende (E.1) der Kavität (8) angeordnete erste Einlassöffnung (11.1) zum Einfüllen des zu extrudierenden ersten Ausgangsstoffs in die Kavität (8) und eine an einem hinteren Ende (E.2) der Kavität (8) angeordnete Extrusionsöffnung (13), wobei die Kavität (8) die zumindest eine Extruderschnecke in der Umfangsrichtung (U) im Wesentlichen umschließt, sodass zwischen der zumindest einen Extruderschnecke und dem Gehäuse (2) ein sich radial erstreckender Spalt ausgebildet ist und wobei der Spalt in einem sich von der ersten Einlassöffnung (11.1) erstreckenden ersten Längenbereich (L.1) der Kavität (8) eine Verjüngung aufweist. Die Erfindung betrifft weiterhin ein Gehäuse (2) für einen solchen Schneckenextruder (1).

摘要: A method of manufacturing a plurality of colors of bulked continuous carpet filament from a single multi-screw extruder which, in various embodiments, comprises: (A) passing PET through an extruder that melts the PET and purifies the resulting PET polymer melt; (B) adding a liquid colorant to the polymer melt using a liquid metering system; (C) using one or more static mixers (e.g., up to forty static mixers) to substantially uniformly mix (e.g., homogeneously mix) the polymer melt and the liquid colorant; and (D) feed the uniformly mixed and colored polymer melt into a spinning machine that turns the polymer into filament for use in manufacturing carpet, rugs, and other products.

摘要: The present invention provides an extruder configured to extrude a solid raw material containing moisture, the extruder comprising: a barrel having a hollow tubular shape in a longitudinal direction, wherein a hopper into which a raw material is put is coupled to one side of the barrel, a discharge port through which a dehydrated raw material is discharged is provided on the other side of the barrel, and a slot portion, through which the inside and outside of the barrel communicate each other, is provided in a specific section between the discharge port and the hopper; a rod-shaped screw provided with screw threads on an outer circumferential surface thereof so that the screw is mounted within the barrel to transfer a raw material put into the hopper to the discharge port while axially rotating in one direction; and a heater part mounted on the barrel to heat the raw material. The raw material introduced into the barrel through the hopper is gradually heated by the heater part while being transferred within the barrel through the screw. A kneading zone, in which raw materials transferred by the screw threads are compressed, is formed on the screw. Since the raw material is melted within the barrel so that at least a portion of the raw material is phase-changed into a liquid state, a heating temperature of the heater part and an axial rotation speed of the screw are controlled so that a sealing membrane that shields an inner transverse section of the barrel is formed from the liquid raw material in the kneading zone.
