Description
Изобретение относитс к переработке вулканизованной резины и может быть использовано дл измельчени изношенных пбкрышек.The invention relates to the processing of vulcanized rubber and can be used for grinding worn seals.
Цель изобретени - сокращение времени измельчени и уменьшение расхода охлаждающего агента.The purpose of the invention is to reduce the grinding time and reduce the consumption of the cooling agent.
На чертеже представлено устройство дл измельчени изношенных покрышек.The drawing shows a device for shredding worn tires.
Устройство представл ет собой технологическую линию, содержащую компрессорную систему подачи охлаждающего агента, включающую емкость 1, например, дл жидкого азота, холодильник 2, компрессор 3 и входной и выходной трубопроводы 4 и 5. рубашки 6 охлаждени , заключающие в себ подающий транспортер 7, снабженный устройством отбора металлических бортовых колец (не показано), узел предварительного измельчени - кузнечный молот 8 и установленную под ним мельницу 9 дл окончательного измельчени . Входы 10 и выходы 11 рубашек 6 охлаждени св заныThe device is a process line containing a compressor cooling agent supply system including a tank 1, for example, for liquid nitrogen, a cooler 2, a compressor 3 and inlet and outlet pipes 4 and 5. a cooling jacket 6 comprising a supply conveyor 7 equipped with a device for selecting metal side rings (not shown), a preliminary grinding unit - a forging hammer 8 and a mill 9 installed under it for final grinding. Inputs 10 and outlets 11 cooling shirts 6 are connected
соответственно с выходом емкости 1 и с входом компрессора 3 посредством трубопроводов 4 и 5. Под мельницей расположены сито 12 и отборочный транспортер 13.respectively, with the output of the tank 1 and with the inlet of the compressor 3 through pipelines 4 and 5. Under the mill are a sieve 12 and a selection conveyor 13.
Работа устройства осуществл етс следующим образом.The operation of the device is as follows.
Жидкий азот из емкости 1 подаетс по трубопроводу 4 на входы 10 рубашек 6 охлаждени , охватывающих подающий транспортер 7, кузнечный молот 8 и мельницу 9, и создает в них необходимую температуру. Испар сь, охлаждающий агент поступает через выходы 11 по трубопроводу 5 в компрессор 3, откуда через холодильник 2 вновь попадает в емкость 1.Liquid nitrogen from the tank 1 is fed through line 4 to the inlets 10 of the cooling shirts 6, covering the feed conveyor 7, the forging hammer 8 and the mill 9, and creates the required temperature in them. After evaporation, the cooling agent enters through the outlets 11 through line 5 to the compressor 3, from where it goes through the cooler 2 to the tank 1 again.
Затем цикл повтор етс .Then the cycle is repeated.
Наличие рубашек 6 охлаждени позвол ет осуществл ть посто нное охрупчивание резины. Полученна крошка через сито 12 подаетс на отборочный транспортер 13. При необходимости оставшуюс в сите 12 крошку можно подвергнуть повторной обработке .The presence of cooling shirts 6 allows for permanent rubber embrittlement. The resulting crumb is passed through a sieve 12 onto a selection conveyor 13. If necessary, the crumb remaining in a sieve 12 can be re-processed.

Таким образом, одновременное осуществление процессов замораживани и переработки позвол ет сократить длительность измельчени покрышек. Повторное использование охлаждающего агента позвол ет уменьшить его расход.Thus, the simultaneous implementation of the processes of freezing and processing reduces the duration of grinding tires. Re-use of the cooling agent reduces its consumption.
