Description
Устройство содержит черв к 1, на конце которого закреплена коническа торпеда 2 с волнообразной наружной поверхностью и с каналами 3 и 4 дл перетока расплава, соедин ющими гребни наружной поверхности торпеды с ее впадинами. Каналы направлены таким образом, что позвол ют перемещать расплав с -большого диаметра наружной поверхности торпеды 2 на меньший диаметр соседней впадины и с меньшего диаметра этого же гребн на больший диаметр соседней впадины. Каналы 3 и 4 торпеды расположены под углом 30-45° к продольной оси черв ка 1, который размещен в гильзе 5, жестко соединенной с насадкой 6, образующей с наружной волнообразной поверхностью торпеды 2 рабочий зазор 7.The device contains a worm to 1, at the end of which a conical torpedo 2 is fixed with a wavy outer surface and with channels 3 and 4 for the melt flow connecting the ridges of the outer surface of the torpedo with its depressions. The channels are directed in such a way that they allow the melt to be moved from the large diameter of the outer surface of the torpedo 2 to the smaller diameter of the adjacent depression and from the smaller diameter of the same crest to the larger diameter of the neighboring depression. Channels 3 and 4 of the torpedo are located at an angle of 30-45 ° to the longitudinal axis of the screw 1, which is placed in the sleeve 5, rigidly connected to the nozzle 6, which forms a working gap 7 with the outer undulating surface of the torpedo 2.
Устройство работает следующим образом .The device works as follows.
Расплав, подаваемый черв ком 1 в гильзе 5, поступает к конической торпеде 2 с волнообразной поверхностью, имеющей каналы 3 и 4. Верхние слои расплава поступают по каналам 4, расположенным на большем диаметре гребн торпеды 2, к меньшему диаметру соседней впадины, а нижние слои расплава поступают по каналам 3, расположенным на меньшем диаметре гребн , к большему диаметру соседней впадины.The melt supplied by the worm 1 in the sleeve 5 enters the conical torpedo 2 with a wavy surface having channels 3 and 4. The upper layers of the melt flow through channels 4 located on the larger diameter of the ridge of the torpedo 2 to the smaller diameter of the adjacent depression and the lower layers the melt flows through the channels 3, located on a smaller diameter of the ridge, to a larger diameter of the adjacent depression.
Гомогенность расплава достигаетс благодар прохождению его по каналам на прот жении всей длины конической торпеды 2.Melt homogeneity is achieved by passing it through the channels over the entire length of the conical torpedo 2.
Данное устройство просто по конструктивному исполнению, не требует какихлибо серьезных затрат на его внедрение и обеспечивает эффективное перемешиваниеThis device is simple in design, does not require any serious costs for its implementation and provides effective mixing
и гомогенизацию расплава полимера. Iand homogenization of the polymer melt. I
