Description
(54) УСТРОЙСТВО ДЛЯ ПЕРЕРАБОТКИ ПОЛИМЕРНЫХ МАТЕРИАЛОВ(54) DEVICE FOR PROCESSING POLYMER MATERIALS
Изобретение относитс к оборудованию дл переработки полимерных МЗ териалов, а более конкретно, к устройству черв чных машин с одним черв ком , предназначенных дл разогрева гомогенизации, пластикации и приготовлени полимерной композиции. Известно устройство дл переработ ки полимерных материалов, содержащее корпус и установленный в нем черв к с нарезкой l. Недостатком устройст ва вл етс невысока степень гомогенизации , низкое качество получаемого продукта. Известно устройство дл переработ ки полимерных материалов, содержащее корпус, установленный в неМ черв к с основной нарезкой и дополнительной, выполненной на сердечнике черв ка между гребн ми основной нарезки с глубиной, меньше глубины основной нарезки 2. Недостатком устройства вл етс невысокое качество получаемого . Цель изобретени - интенсификаци процесса переработки и улучшение качества продукта. Поставленна цель достигаетс тем ITO в устройстве дл переработки полимерных материалов, содержащем корпус , установленный в нем черв к с основной нарезкой и дополнительной, выполненной на сердечнике черв ка между гребн ми основной нарезки с глубиной, меньше глубины основной нарезки, согласно изобретению, дополнительна нарезка выполнена на гребн х основной нарезкн, причем направление дополнительной нарезки выполнено противоположнь направлению основной нарезки . Изобретение по сн етс чертежом, где изобр 1жен общий вид устройства. Устройство содержит корпус 1, установленный в нем черв к 2 с основной нарезкой 3 и дополнительной 4, выполненной на сердечнике черв ка 2 между гребн ми основной нарезки 3. Дополнительна нарезка 4 выполнена и на гребн х основной нарезки 3, причем направление дополнительной нарезки 4 выполнено противоположным направлению основной нарезки 3. Полимерный материал с ингредие -: тами подают в загрузочную воронку {ра чертеже не показана). В процессе вращени черв ка 2 в корпусе 1 материал , нар ду с преимущественным движением от загрузочной воронки к головке (на чертеже не показана), заThe invention relates to equipment for the processing of polymeric MH materials, and more specifically, to the design of single-worm screw machines for heating up homogenization, kneading and preparation of a polymer composition. A device for processing polymeric materials is known, comprising a housing and a screw installed therein with a thread l. The disadvantage of the device is a low degree of homogenization, low quality of the product. A device for processing polymeric materials is known, comprising a casing installed in the core with a main thread and an additional one made on the core of the screw between the ridges of the main thread with a depth less than the depth of the main thread 2. A disadvantage of the device is the low quality of the product. The purpose of the invention is to intensify the processing process and improve the quality of the product. This goal is achieved by ITO in a device for processing polymeric materials, which contains a case, installed a worm with main cutting and an additional wound between the crests of the main cutting with a depth less than the depth of the main cutting made on the core of the worm, and additional cutting is performed on the ridge of the main thread, and the direction of the additional thread is made opposite to the direction of the main thread. The invention is illustrated in the drawing, where the image is a general view of the device. The device comprises a housing 1 installed in it a worm to 2 with a main thread 3 and an additional 4 made on the core of a worm 2 between the crests of the main carving 3. Additional carving 4 is also performed on the crests of the main carving 3, and the direction of the additional carving 4 is done opposite to the direction of the main cutting. 3. Polymer material with ingredia -: Tami are fed into the feed hopper (not shown in the drawing). In the process of rotation of the screw 2 in the housing 1, the material, along with the preferential movement from the hopper to the head (not shown),
счет основной нарезки 3 совершает возвратное перемещение и циркул цию за счет дополнительной нарезки 4 в пределах каждого витка основной нарезки 3 и приобретает необходимые свойства. По выходе из головки его срезают и подают на последу1с цие технологические операции, и таким образом непрерывно осуществл етс процес переработки.the account of the main thread 3 makes a return movement and circulation due to the additional thread 4 within each turn of the main thread 3 and acquires the necessary properties. Upon leaving the head, it is cut off and fed to the subsequent technological operations, and thus the processing is carried out continuously.
В результате возвратных потоков материалов и его циркул ции в пределах каждого витка основной нарезки (внешний перемешивающий эффект), а также вследствие дополнительных напржений сдвига, создаваемых дополнительной нарезкой (внутренний переме .шивающий эффект), устройство обеспечивает интенсификацию процесса перерботки и улучшение качества продукта, благодар более равномерному распределению ингредиентов во всей смешиваемой массе.As a result of the return flow of materials and its circulation within each turn of the main cutting (external mixing effect), as well as due to additional shear stresses created by additional cutting (internal mixing effect), the device provides an intensification of the recycling process and improvement of the product quality due to more uniform distribution of ingredients in the whole mix.
