Description

ЧЕРВЯЧНО-ДИСКОВЫЙ ЭКСТРУДЕР ДЛЯ ПЕРЕРАБОТКИ ПОЛИМЕРНЫХ МАТЕРИАЛОВ Известен черв чно-дисковый экструдер дл  переработки полимерных материалов, содержащий соосно установленные в корпусе и снабженные индивидуальными приводами полый транспортирующий черв к и диск, образующий с корпусом рабочий зазор. В описываемом устройстве полый транспортирующий черв к установлен на ступице неподвижного конуса, образующего с корпусом сужающуюс  щель, переход щую в рабочий зазор между корпусом И диском, благодар  чему стабилизируетс  1процесс экструзии. На чертеже изображен черв чно-дисковый экструдер. Черв чно-диоковый экструдер содержит -вращающийс  диск /, paз мeщeнный в неподвижном корпусе 2, в торцовой части которого расположен формующий инструмент . К фланцу корпуса 2 крепитс  неподвижный корпус 4 с загрузочным бункером 5. В корпусе 4 соосно с диском / расположен полый транспортирующий черв к 6. Между черв ком и вращающимс  диском расположен неподвижный конус 7, на ступице 8 которого установлен упом нутый черв к. Конус 7 с неподвижным KopnycoiM 4 образуют сужающуюс  щель а, переход щую в рабочий зазор б экструдера . Черв к 6 имеет индивидуальный при-вод 9.. Исходный материал из загрузочного бункера 5 поступает на вращающийс  транспортирующий черв к 6, который перемещает его в направлении неподвижного конуса 7. Далее материал поступает в сужающуюс  щель а, образованную конусом 7 и неподвижным корпусом 4, где он формуетс  в непрерывный кольцеобразный столб, уплотн етс  и направл етс  в экструдер одновременно по всему сечению его рабочего зазора б. Оптимальное число оборотов черв ка подбираетс  при помощи индивидуального привода 9. Подача материала в экструдер одновременно по всему сечению его рабочего зазора устран ет неравномерности загрузки и способствует стабилизации процесса экструзии. Предмет изобретени  Черв чно-дисковый экструдер дл  переработки полимерных материалов, содержащий соосно установленные в корпусе и снабженные индивидуальными приводами полый транспортирующий черв к и диск, образующий с корпусом рабочий зазор, отличающийс  тем, что, с целью стабилизации процесса экструзии, между дисками и черв ком расположен неподвижный конус, сна:бл{ен1ный ступицей, ;на который установлен черв к и образующий с корпусом сужающуюс  щель, переход щую в рабочий зазор.WARMER-DISK EXTRUDER FOR PROCESSING POLYMERIC MATERIALS A worm-disk extruder for processing polymeric materials is known, containing coaxially mounted in a housing and equipped with individual drives, a hollow transporting worm to and a disk forming a working gap with the housing. In the described device, a hollow transporting worm is mounted on the hub of a stationary cone, which forms a narrowing slit with the casing, which converts into the working gap between the casing AND the disk, thereby stabilizing the extrusion process. The drawing shows a screw-disk extruder. The screw-die extruder contains a rotating disk /, once placed in a stationary body 2, in the end part of which the forming tool is located. A fixed body 4 with a hopper 5 is fixed to the flange of the housing 2. In the housing 4 coaxially with the disk / there is a hollow transporting screw to 6. Between the screw and the rotating disk there is a fixed cone 7, on the hub 8 of which the mentioned worm is mounted. Cone 7 with a fixed KopnycoiM 4 they form a narrowing slit a, which passes into the working gap b of the extruder. Worm to 6 has an individual drive 9 .. Source material from loading hopper 5 enters the rotating conveyor worm to 6, which moves it in the direction of the fixed cone 7. Next, the material enters the narrowing slit a formed by the cone 7 and the fixed case 4, where it is molded into a continuous annular pillar, compacted and guided into an extruder simultaneously over the entire cross section of its working gap b. The optimum speed of the screw is selected using an individual drive 9. The feeding of the material into the extruder simultaneously over the entire cross section of its working gap eliminates uneven loading and contributes to the stabilization of the extrusion process. The subject of the invention is a screw-disk extruder for processing polymeric materials containing a hollow transporting screw worm coaxially mounted in a housing and equipped with individual drives and a disk forming a working gap with the housing, characterized in that, in order to stabilize the extrusion process, between the drives and the screw there is a fixed cone, sleep: a fucking hub, on which a screw is mounted and which forms a narrowing slit with the body, passing into the working gap.
