Description

торого й1вл етс  радиально-упорный подшипник 5, Враше1ше валу передаетс  от внешнего привода (на чертеже не показан ). На боковой поверхности диска 1 выполнена вшгтова  нарезка 01 дл  првдотврашещ  попадаш1  k -ejSifaSa в . подшипника, В диске 1 и корпусе 2 на рабочей поверхности вьшолнены капил п рные каналы 6, которые выход т в полости 7 и 8, выполненные, в диске и корпусе. Полости 7 и 8 соединены при йомЬщи воздушного трубопровода 9 с системой iO регулировани  давлени  газа . Дл  загрузки перерабатываекфгр материала установлен буюсер 11, В корпусе 2 п6 оси вращени  диска 1 выполнено выходное отверстие 12,Secondly, the radial thrust bearing 5 is inserted into the shaft and transmitted to the shaft from an external drive (not shown). On the side surface of the disk 1, a pin-cutting 01 is made for a pre-assembly step 1 k -ejSifaSa c. the bearing, In the disk 1 and the housing 2 on the working surface there are made up the capillary channels 6, which extend into the cavities 7 and 8, made in the disk and housing. Cavities 7 and 8 are connected, when the air line 9 is located, to the iO system of gas pressure control. To load the material in process, a buoyser 11 is installed. In the case 2, p6 of the axis of rotation of the disk 1 an outlet 12 is made,

Работа устройства осуществл етс  следующим образом.The operation of the device is as follows.

Перерабатываемый материал из бункера 11 поступает в рабочий зазор 3 экструдера где он пластииируетс . Система 10 регулировани  давлетга  газа работает в режиме создани  разрежени  в рабочем зазоре, при этом расплав полимерного материала прит гиваетс  к рабочим поверхност м диска 1 и корпуса 2, Благодар  капилл рным силам не происходит затекани  расплава в капилл рные каналы,The processed material from the hopper 11 enters the working gap 3 of the extruder where it is plastified. The gas pressure control system 10 operates in the mode of creating a vacuum in the working gap, while the polymer melt is attracted to the working surfaces of the disk 1 and the housing 2. Due to capillary forces, the melt does not flow into the capillary channels,

В процессе работы дискового экструдера происходит также отсасывание газа Из расплава полимера.During the operation of a disk extruder, gas is also sucked from the polymer melt.

После окончани  работы производитс  переключение системы 10 регулировани  давлени  газа на режим Новышенц  давлени  в полость 7 и S, при очищакугс  капилл рные 6 и производитс  продувка рабочёгб зазор акстру ера.After completion of the work, the gas pressure control system 10 is switched to the Novyshents pressure mode in cavity 7 and S, with the capillary gas cleaned 6 and the working gap is filled with a gap.

Снабжение дискового экст)удера системой регулировани  давлени  газа и выполнение в корпусе и диске капилл рных каналов позволит регулировать произво . -ди ельность экструдера, не измен   скорости враи1е1ш  диска, что достигаетс Supplying the disk extruder system with a gas pressure regulating system and performing capillary channels in the housing and disk will allow production to be adjusted. -duality of the extruder, do not change the speed of the spinner disk, which is achieved

путем изменени  степени.разреже1ш  в рабочем зазоре экструдера, что создает услови  принудительного прилипашш перерабатываемого материала к рабочим поверхност м корпуса и диска и исключает возможность проскальзывани  матерйала имеющее место при .работе известных дисковых экструдеров. Принудительное прилипание приводит к увеличению напр жений сдвига в полимерном материале и, соответственно, к увеличению производительности при той же скорости вращени  диска. При создагога повышенного давлеш5Я, обеспечива. самоочистка рабочей зоны экстру- дера ol- перерабатываемого материала. Кроме того, в:ьшолнеЮ1е капилл рных каналов в корпусе и диске способствует удалегшю газов из расплава полимера, что повышает качество экструдера.by changing the degree of expansion in the working gap of the extruder, which creates conditions for the forced sticking of the processed material to the working surfaces of the housing and the disk and eliminates the possibility of material slippage that occurs during the work of known disk extruders. Forced adhesion leads to an increase in shear stresses in the polymer material and, accordingly, to an increase in productivity at the same speed of rotation of the disk. When creating increased pressure, providing. self-cleaning of the working zone of the extruder ol-recycled material. In addition, in: the wave of capillary channels in the housing and the disk contributes to the removal of gases from the polymer melt, which improves the quality of the extruder.
