Patent ES-369008-A1 (ES)
Title: Screw extruders with dual section ejection zone
IPC: B29C48/68
Filed: 1969-07-01
Abstract: A screw extruder, particularly intended for the working of thermoplastics such as polyethylene, polypropylene and polyamide, when of high viscosity, comprises a discharge zone C which has a section C 2 from 1-8 times the length of section C 1 wherein the thread depth is greater, preferably two to five times greater, than in section C,. As shown, the greater thread depth is achieved by a reduction in the screw core diameter and such a reduced core may have a constant diameter or taper downstream, see Fig. 3 (not reproduced). Alternatively barrel 1 may increase in internal diameter, see Fig. 4 (not reproduced), the thread increasing in depth on a constant diameter core. To further reduce shearing forces in section C 2 , the thread may be spaced a greater distance from the interior of the barrel than in section C 1 , see Figs. 2-4 (not reproduced). The thread pitch is preferably varied so as to give a constant throughput in particular the pitch is less in section C 2 than in section C 1 see Figs. 2-4 (not reproduced). Alternatively with constant pitch in section C 2 , the thread may be provided with breaks or perforations. Camlike projections or other mixing elements may be attached to the screw core. Melting of the thermoplastic material in zones A-B is both by frictional working and by supplying heat. Independently operable heating and/or cooling devices may be associated with section C 2 , as at (9), Fig. 4 (not shown).
