Изобретение относитс  к области переработки полимерных материалов в экструдерах дл  переработки высоков зких полимеров .This invention relates to the field of processing polymeric materials in extruders for processing highly viscous polymers.

Известен экструдер дл  переработки полимерных материалов, содержащий черв к .и диск, образующий с корпусом рабочий .зазор 1.A extruder for processing polymeric materials is known, which contains a screw k. And a disk, which forms a working gap with the body.

Существенным недостатком указанного экструдера  вл етс  мала  эффективность переработки материала, так как она зависит от частоты оборотов пластицирующего элемента - диска, котора  ограничена ве .личиной забора материала, подлежащего пластицированию.A significant disadvantage of this extruder is the low efficiency of processing the material, since it depends on the frequency of revolutions of the plasticizing element — a disk, which is limited by the size of the intake of the material to be plasticized.

Наиболее близким к изобретению по техническому решению  вл етс  экструдер дл  переработки полимериых материалов, содержащий корпус, подающий щнек с приводом вращени , транспортирующий шнек и размещенный между щнеками пластицирующий элемент, выполненный в виде закрепленных на торцах щнеков двух дисков 2. Транспортирующий щнек приводитс  во вращение от привода подающего щнека.The closest to the invention according to the technical solution is an extruder for processing polymeric materials, comprising a housing, feeding rotary drives, transporting augers and a plasticizing element placed between the screws, made in the form of two screws fixed at the ends of the screws 2. drive feed screw.

Недостатком указанного экструдера  вл етс  плоха  переработка материалов с повышенной степенью в зкости, неэффективность переработки различных материалов с разными физико-механическими свойствами из-за малой величины поверхностей, ограничивающих пластицирующнй рабочий зазор и из-за посто нства числа оборотов пластицирующего элемента.The disadvantage of this extruder is the poor processing of materials with a high degree of viscosity, the inefficiency of processing various materials with different physicomechanical properties due to the small size of the surfaces that limit the plasticizing working gap and the constant number of revolutions of the plasticizing element.

Целью изобретени   вл етс  интенсификаци  процесса пластикации материала.The aim of the invention is to intensify the process of kneading the material.

Достигаетс  указанна  цель благодар  тому, что в экструдере дл  переработки полимерных материалов, содержащем корпус, подающий шнек с приводом вращени , транспортирующий щнек и размещенный между шнеками пластицирующий элемеит, выполненный в виде закрепленных на торцах щнеков двух дисков, согласно изобретению , один из дисков пластицирующего элемента выполнен с полостью, в которой размещен второй диск с образованием между ними рабочего зазора дл  расплаваThis goal is achieved due to the fact that in an extruder for processing polymeric materials, comprising a housing, a feed screw with a rotation drive, transporting a screw and a plasticizing element placed between the screws, made in the form of two disks mounted on the ends of the screws, the plasticizing element made with a cavity in which is placed the second disk with the formation between them of the working gap for the melt

материала, а транспортирующий щнек снабжен индивидуальным приводом вращени , уплотнением, расположенным между его нарезкой и диском, и выполнен с каналом дл  сообщени  рабочего зазора между дисками с межвитковым каналом транспортирующего шнека.material, and the transporting puppy is provided with an individual rotational drive, a seal located between its cutting and the disk, and is provided with a channel for communicating the working gap between the disks with the interturn channel of the transporting screw.

На чертеже изображен экструдер в разрезе . Экструдер состоит из корпуса 1, имеющего загрузочное отверстие 2 и отверстиеThe drawing shows the extruder in the section. The extruder consists of a housing 1 having a loading opening 2 and an opening
