Изобретение относитс к оборудованию дл переработки термопластов, про вл ющих при нагреве и сдвиге высокоэластичные свойства, оно может быть использовано в экструзионных установках, а также в качестве предпластикатора литьевой или выдувной машины.The invention relates to equipment for processing thermoplastics, which exhibits highly elastic properties during heating and shearing, it can be used in extrusion plants, and also as a preplasticizer for injection molding or blow molding machines.
Известен дисковый экструдер, содержаид,ий снабженный загрузочной воронкой и фильерой корпус, в котором соосно установлены полый черв к и диск, выступающий относительно торца черв ка и образующий с внутренней поверхностью корпуса рабочий зазор, и приводы дл вращени черв ка и диска. Недостатком известного экструдера вл етс плоха перемещивающа способность, чЮ приводит к получению некачественного издели и снижает производительность экструдера .A disk extruder is known, comprising a housing in which a hollow screw is coaxially mounted and a disk protruding relative to the end of the screw and forming a working gap with the inner surface of the housing, and drives for rotating the screw and the disk. A disadvantage of the known extruder is the poor displacement capacity, which results in a poor quality product and reduces the performance of the extruder.
С целью интенсификации процесса перемещивани в онисываемом дисковом экструдере на торце черв ка выполнены выступы, например в виде лопаток, а на боковой поверхностп выступающей части диска укреплены лопасти.In order to intensify the movement process in an on-disk extruder, protrusions are made at the end of the screw, for example, in the form of blades, and the blades are fixed on the side surface of the protruding part of the disk.
Предлагаемый экструдер показан па фиг. 1 и 2, где на фиг. 1 дан продольный разрез его, а на фиг. 2 - разрез экструдера по А-А на фиг. 1.The proposed extruder is shown pas FIG. 1 and 2, where in FIG. 1 is a longitudinal section of it, and in FIG. 2 is a section through an extruder along A-A in FIG. one.

The disk 8 is provided with blades 17, which are fixed on the side surface of its protruding part and with protrusions 14 form an offset displacement, g. On the screw worm 13 or disk 8, a sealing is made (left or right depending on the direction of rotation of the disk).
