Изобретение относитс к области переработки полимерных материалов и может быть использовано дл смешени полимерных композиций и полимеров с различными ингредиентами.The invention relates to the field of processing polymer materials and can be used to mix polymer compositions and polymers with various ingredients.
.Известен статический смеситель дл полимерных материалов, содержащий трубчатый корпус и смесительные элементы со сквозными каналами, установленные в корпусе .A static mixer for polymeric materials is known comprising a tubular body and mixing elements with through channels installed in the body.
Недостатком такого смесител вл етс низка гомогенность расплава, т.к. при сли нии потоков из отдельных сквозных каналов в единый поток, образуютс спаи неоднородности.The disadvantage of this mixer is the low homogeneity of the melt, because when the flows from separate through channels merge into a single stream, junctions of inhomogeneities are formed.
Известен статический смеситель дл полимерных материалов, состо щий из корпуса , в котором размещен пучок труб с прорез ми и насадками.A static mixer for polymeric materials is known, consisting of a housing in which a tube bundle with slots and nozzles is placed.
К недостаткам такого статического смесител следует отнести наличие застойных зон у перемычек между прорез ми, выполненными в трубах и на выходе из насадок, что приводит к ухудшению качества расплава .The disadvantages of such a static mixer include the presence of stagnant zones at the bridges between the slots made in the pipes and at the outlet of the nozzles, which leads to a deterioration in the quality of the melt.
Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс статический смеситель дл полимерных материалов, содержащий корпус и размещенный внутри него пучок труб с насадками. К недостаткам этого смесител следует отнести недостаточную разделительную способность вследствие малого количества дроблений лотока.The closest in technical essence and the achieved result to the invention is a static mixer for polymeric materials, comprising a housing and a bundle of pipes with nozzles placed inside it. The disadvantages of this mixer include insufficient separation ability due to the small number of crushing of the tray.
Целью изобретени вл етс повышение качества расплава.The aim of the invention is to improve the quality of the melt.

На фиг. 1 показан статический смеситель дл полимерных материалов; на фиг. 2 - в увеличенном масштабе трубка с насадкой .In FIG. 1 shows a static mixer for polymeric materials; in FIG. 2 - an enlarged scale tube with a nozzle.
Статический смеситель дл полимерных материалов содержит корпус 1, в котором размещен пучок труб 2, нижние части которых выполнены с пилообразными вырезами 3. При этом в нижней части труб 2 размещены насадки 4. выполненные конусообразными , обращенными вершинами вверх, а нижний конец 5 насадок 4 выполнен сферическим.The static mixer for polymeric materials contains a housing 1, in which a bundle of pipes 2 is placed, the lower parts of which are made with sawtooth cutouts 3. At the same time, nozzles 4. are placed in the lower part of the pipes 2. spherical.
Работа статического смесител дл полимерных материалов заключаетс в следующем . Поток расплава полимера с различными ингредиентами подаетс , например , из черв чного пресса (не показан) в корпус 1 статического смесител попадает в пучок труб 2, где раздел ютс на множе- СТЁО новых потоков, увеличива при этом число новых полос компонентов.The operation of a static mixer for polymeric materials is as follows. A polymer melt stream with various ingredients is supplied, for example, from a screw press (not shown) into the housing 1 of the static mixer and into a tube bundle 2, where it is divided into many new flows, increasing the number of new component bands.
Затем потоки расплава из каждой трубки 2 вытекают через пилообразные прорези в разные вырезы 3, не образу при этом застойных зон, т.к. между нижними концами вырезов 3, примыкающих к насадке 4, нет перемычек. Затем потоки расплава плавно стекают по сферическому концуThen, the melt flows from each tube 2 flow out through sawtooth slots into different cutouts 3, without creating stagnant zones, since between the lower ends of the cutouts 3 adjacent to the nozzle 4, there are no jumpers. Then the melt flows smoothly down the spherical end
насадки 4 в общий поток, причем поскольку поток обтекает сферический конец 5 насадки 4, не срываетс с цилиндра, то в этом месте отсутствуют застойные зоны расплава .nozzles 4 into the common stream, and since the stream flows around the spherical end 5 of nozzle 4, does not break from the cylinder, there are no stagnant melt zones at this point.
Сочетание пилообразных вырезов 3 на нижних концах труб 2 и коническо-сфериче- ских насадок 4 позвол ет получать систему мелких потоков с большой вновь образован- ной поверхностью при беззастойном течении .The combination of sawtooth cutouts 3 at the lower ends of the pipes 2 and conical-spherical nozzles 4 makes it possible to obtain a system of shallow flows with a large newly formed surface in an unstable flow.
Таким образом, в статическом смесителе данной конструкции достигаетс повышение качества расплава за счет отсутстви в нем застойных зон расплава. Смеситель также вл етс самоочищающимс , что особенно важно при переработке нетермоста- бильных полимерных материалов. Кроме того, предполагаетс получить экономиче- ский эффект за счет снижени потерь от брака при экструзии и литье под давлением полимерных материалов.Thus, in a static mixer of this design, an increase in the quality of the melt is achieved due to the absence of stagnant melt zones in it. The mixer is also self-cleaning, which is especially important when processing non-heat stable polymer materials. In addition, it is planned to obtain an economic effect by reducing losses from marriage during extrusion and injection molding of polymeric materials.
