Description

Изобретение относитс  к переработке полимеров , в частпости касаетс  конструкции экструдеров-смесителей, используемых дл  получени  материалов с интенсивной и качественной гомогенизацией и равномерными физико-механическими свойствами при окра- нивании или смешивании двух или более полимеров с различными свойствами в химической промышленности, в машиностроении .The invention relates to the processing of polymers, in particular, to the design of extruders-mixers used to obtain materials with intensive and high-quality homogenization and uniform physicomechanical properties when coloring or mixing two or more polymers with different properties in the chemical industry, in engineering.

Цель изобретени  - повышение качества материалов за счет интенсификации их смешени  и гомогенизации.The purpose of the invention is to improve the quality of materials due to the intensification of their mixing and homogenization.

На фиг. 1 показан экструдер-смеситель, продольный разрез; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows an extruder-mixer, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

Экструдер-смеситель дл  полимерных материалов содержит цилиндрический корпус 1 с выходным отверстием 2, размещенный в корпусе 1, расплавитель 3 со смесительным приспособлением, выполненным в виде смон- тированны с возможностью вращени  (в данном случае за счет соединени  с рас- плавителем 3) черв ка 4 и охватывающей его перфорированной гильзы 5, которые расположены на конце расплавител  3 перед выходным отверстием 2. Расплавитель 3 снабжен набором перфорированных трубок 6,The extruder-mixer for polymeric materials contains a cylindrical case 1 with an outlet 2 placed in case 1, the melter 3 with a mixing device made rotatably mounted (in this case due to connection with the melter 3) a screw. 4 and the perforated sleeve 5 that surrounds it, which are located at the end of the melter 3 in front of the outlet 2. The melter 3 is provided with a set of perforated tubes 6,

заполненных статическими смесительными элементами 7 и неподвижно установленных ио диаметру между черв ком 4 и перфорированной гильзой 5.filled with static mixing elements 7 and fixedly mounted with the diameter between the screw 4 and the perforated sleeve 5.

Экструдер-смеситель работает следую- гцим образом.The extruder mixer works in the following manner.

Расплав, подаваемый раснлавителем 3, проходит через перфорированную гильзу 5, раздел  сь на отдельные потоки, затем пере- .мешиваетс  и гомогенизируетс  в полост х меж.ау перфорированной гильзой 5 и перфорированными трубками 6 и черв ком 4 за счет сдвиговых потоков между ними. Дальнейшее перемешивание расплава осу- п.ествл етс  за счет разделени  потоков расплава в перфорированных трубках 6 и размещенными в них статическими с.меси- тельными элементами 7.The melt supplied by the resolver 3 passes through the perforated sleeve 5, divided into separate streams, then mixed and homogenized in the cavity between the perforated sleeve 5 and the perforated tubes 6 and the worm 4 due to the shear flows between them. Further mixing of the melt is accomplished by separating the melt streams in the perforated tubes 6 and the static sizing elements 7 placed in them.

Таким образом, перфорированные трубки 6 и статические смесительные элементы 7  вл ютс  сдвиговым элементом между вра- ш,ающейс  перфорированной гильзой 5 и чер- 4. Кроме того, разделение и смен1е- пие потоков осундествл етс  как за счет перфорации перфорированных трубок 6, так и за счет значительного количества статических смесительных элементов 7, установленных в них.Thus, the perforated tubes 6 and the static mixing elements 7 are a shear element between the spigot, the perforated sleeve 5 and the black 4. In addition, the separation and replacement of the flow will be made through the perforations of the perforated tubes 6 and due to the significant number of static mixing elements 7 installed in them.
