Description
(54) ЭКСТРУДЕР ДЛЯ ПЕРЕРАБОТКИ ПОЛИМЕРНЫХ МАТЕИИАЛОВ(54) EXTRUDER FOR PROCESSING POLYMER MATERIALS
Работает устройство следующим образом.The device works as follows.
Исходный материал в виде полимерной компоЗИ1ШИ из загрузочной горловины 3 поступает на черв к 7, захватываетс его витками и перемещаетс к конусу 8. Материал, попавший на конус 8, подогреваетс нагревателем 4, расплавл етс и перемещаетс прерывистой винтовой нарезкой на диск 11, который может совершать осевое перемещение в центральной полости 10 конуса 8. В зазоре между диском 11 и торцовой крышкой 5 материал смешиваетс , пластицируетс , гомогенизируетс и вьщавливаетс через экструзионное отверстие 6.The source material in the form of polymer composite from the loading neck 3 enters the screw to 7, is captured by its turns and moves to the cone 8. The material caught in the cone 8 is heated by the heater 4, melts and moves intermittently to a disk 11, which can be made axial movement in the central cavity 10 of the cone 8. In the gap between the disk 11 and the end cover 5, the material is mixed, plasticized, homogenized and pressed through the extrusion hole 6.
При увеличении подачи материала диск 11 входит в центральную полость 10 и открывает проходные окна 14, соедин ющие боковое межвитковое пространство 15 конуса с его центральной полостью 10. Фиксаци положений диска 11 в центральной полости осуществл етс при помощи узла 13, При уменьшении подачи материала диск 11, перемеща сь, перекрывает проходные окна 14.When the material supply is increased, the disk 11 enters the central cavity 10 and opens passage openings 14 connecting the lateral interturn space 15 of the cone with its central cavity 10. The positions of the disk 11 in the central cavity are fixed by means of the node 13. , moving, overlaps through the window 14.
Предлагаемый зкструдер позвол ет выбирать оптимальную величину рабочего зазора в зависимЬсги от неравномерности загрузки перерабатываемого материала в экструдер, что повышает производительность на 10-12 %.The proposed extruder allows you to select the optimum size of the working gap depending on the uneven loading of the material being processed into the extruder, which increases productivity by 10-12%.
Экономи«кска эффективность предлагаемого устройства заключаетс в устранении простоев оборудовани , св занных с переналадкой рабочего зазора , в стабилизации процесса зкструзии и в расширении возможностей регулировани технологических режимов экструзии.The economy of the proposed device is to eliminate equipment downtime associated with the changeover of the working gap, to stabilize the process of extrusion and to expand the possibilities of regulating the technological modes of extrusion.
