Изббретение относитс к переработ ке полимерных материалов и может Оыть использовано в установках дл производства труб путем экструзии в химической промышленности.The avoidance relates to the processing of polymeric materials and can be used in installations for the production of pipes by extrusion in the chemical industry.
Целью изобретени вл етс повышение производительности процесса охлаждени трубчатых изделий, получае- мых путем экструзии расплава поли- мера через экструзионную головку.The aim of the invention is to increase the productivity of the process of cooling tubular products obtained by extruding a polymer melt through an extrusion die.
Способ включает распыление хлад- агента в полости перемещаемого из- дели и удаление образовавшихс при охлаждении газообразных продуктов из полости издели до их конденсации в направлении, противоположном перемещению издели , а также удаление образовавшихс при охлаждении газообразных продуктов отсосом через экструзионную головку.The method involves spraying the refrigerant in the cavity of the transported product and removing gaseous products formed during cooling from the product cavity prior to their condensation in the direction opposite to the product movement, as well as removing gaseous products formed during cooling by suction through the extrusion head.
На чертеже схематично изображено устройство дл осуществлени предлагаемого способа.The drawing schematically shows a device for carrying out the proposed method.
Устройство содержит экструзионнуго 25 головку 1, соосно с которой смонти- . рбван вакуумный калибратор 2, сообщенный посредством трубы 3 с вакуумным насосом f, камеры 5 охлаждени с раз- меиенными в ней коллектором 6 впрыска и коллектором 7 продувки, сооб- тенными соответственно трубами 8 и 9 с источниками воды и воздуха. Устройство содержит также смонтированную в полости вакуумного калибратора 2 форсунку 10, сообщенную трубами П и 12 соответственно с источниками воздуха и воды. Устройство оснащено смонтированным в экструзионной головке 1 трубопроводом 13, сообщенным с вентил тором 14. В стенке камеры 5 охлаждени выполнены вьшускные отверсти 15.The device contains extrusion 25 head 1, which is aligned with which is mounted. A vacuum calibrator 2, connected via pipe 3 to the vacuum pump f, cooling chamber 5 with the injection manifold 6 spaced therein and purge collector 7, and pipes 8 and 9 respectively with water and air sources, is connected. The device also contains a nozzle 10 mounted in the cavity of a vacuum calibrator 2, communicated with pipes P and 12, respectively, with sources of air and water. The device is equipped with a pipe 13 mounted in the extrusion head 1, communicating with a fan 14. In the wall of the cooling chamber 5, outlets 15 are made.
Устройство работает следующим образом.The device works as follows.
Полимерное погонажное трубчатое, например трубу 16 экстрагируют посредством экструзионной головки 1, пропускают через вакуумный калибратор 2 с приданием трубе 16 точной формы на наружной поверхности и че- 50 рез камеру 5 охлаждени . При этом на30A polymer molded tubular, for example, pipe 16 is extracted by means of an extrusion head 1, passed through a vacuum calibrator 2 to give the pipe 16 a precise shape on the outer surface and through a cooling chamber 5.

ружную поверхность трубы 16 охлаждают совместным действием подаваемой через коллектор 6 впрыска воды и подаваемого через коллектор 7 продувки воздуха. Отработанную водо- воздушную смесь удал ют из камеры 5 охлаждени через отверсти 15. Охлаждение внутренней поверхности трубы 16 осуществл ют совместным действием подаваемых в форсунку 10 воды и воздуха с одновременным уда - лением из полости трубы 16 образовавшихс при охлаждении газообразных продуктов по трубопроводу 13 через вентил тор 14. Удаление газообразных продуктов из полости трубы 16 в направлении, противоположном ее движению, способствует предотвращению их конденсации, что обеспечивает достижение повьш1енной производительности процесса охлаждени трубы 16.The outer surface of the pipe 16 is cooled by the joint action of the water injection through the collector 6 and the air blowing through the collector 7. The waste water-air mixture is removed from the cooling chamber 5 through the holes 15. Cooling the inner surface of the pipe 16 is carried out by the joint action of water and air supplied to the nozzle 10 while simultaneously removing the gas 16 from the cavity by cooling the gaseous products through the pipe 13 through the valve torus 14. Removal of gaseous products from the cavity of the pipe 16 in the direction opposite to its movement, helps prevent their condensation, which ensures the achievement of increased performance pipe cooling process 16.
Удаление образовавшихс при охлаждении газообразных продуктов отсосом через экструзионную головку способстствует наиболее интенсивному охлаждению экструдируемого издели .The removal of gaseous products formed by suction through a die leads to the most intensive cooling of the extruded product.
