Description

Изобретение относитс  к переработке отработанных резинотехнических изделий и может быть использовано при переработке изношенных покрышек колесных машин на регенераторных заводах.The invention relates to the processing of used rubber products and can be used in the processing of worn tires of wheeled vehicles in regeneration plants.

Целью изобретени   вл етс  повышение Технолоничности извлечени  металлической арматуры.The aim of the invention is to increase the Technolonicity of the extraction of metal reinforcement.

На фиг.1 показано начало обработки; на фит,2- покрышка после нагрева металлической арматуры и отделени  каркаса от протектора; на фиг.З - покрышка с разрезанным каркасом и протектором; на фиг.4-6-варианты выполнени  предложенного способа.Figure 1 shows the start of processing; on fit, 2- tire after heating the metal reinforcement and separating the frame from the tread; in Fig.Z - tire with a cut frame and tread; Figures 4-6 show embodiments of the proposed method.

Устройство дл  выполнени  способа содержит индуктор 1, выполненный из металлической трубки в виде петли, рабоча  часть 2 которого примыкает к поверхности каркаса 3 обрабатываемой покрышки 4.The device for carrying out the method comprises an inductor 1 made of a metal tube in the form of a loop, the working part 2 of which is adjacent to the surface of the frame 3 of the processed tire 4.

Между каркасом 3 и протектором 5 покрышки 4 расположён подушечный слой 6, который включает несколько слоев арматуры - обрезйненных стальных нитей 7.Between the frame 3 and the tread 5 of the tire 4 there is a pillow layer 6, which includes several layers of reinforcement - rubberized steel threads 7.

Индуктор 1 выполнен таким образом, что его рабоча  часть 2 перекрывает всю шину подушечного сло  6. Концы 8 индуктора 1 присоединены к источнику переменного электрического тока высокой частоты.The inductor 1 is designed in such a way that its working part 2 overlaps the entire tire of the pillow layer 6. The ends 8 of the inductor 1 are connected to a high frequency alternating current source.

По обе стороны зоны нагрева покрышки 4 вдоль ее поперечного сечени  могут быть установлены прижимы 9, которые прижимают каркас 3 к протектору 5 и тем самым герметизируют зону нагрева, что предотвращает выход газа, образующегос  при плавлении резины. Полость 10, образованна  между каркасом 3 и протектором 5, может быть соединена со специальной емкостью 11 при помощи полой иглы 12 и трубопровода 13.Clamps 9 can be installed on both sides of the heating zone of the tire 4 along its cross section, which press the carcass 3 against the tread 5 and thereby seal the heating zone, which prevents the escape of gas generated when the rubber melts. The cavity 10 formed between the frame 3 and the tread 5 can be connected to a special container 11 using a hollow needle 12 and a pipe 13.

Извлечение арматуры - стальных нитей 7 из покрышки 4 производ т следующим образом. При помощи индуктора 1 на покрышку 4 воздействуют электромагнитным полем высокой частоты, в результате чего в зоне, расположенной под индуктором 1, стальные нити 7 разогреваютс  и оплавл ют окружающую их резину. После расплаелеел СRemoving the reinforcement - steel threads 7 from the tire 4 is carried out as follows. Using the inductor 1, the tire 4 is exposed to a high frequency electromagnetic field, as a result of which, in the zone located under the inductor 1, the steel filaments 7 are heated and melted around their rubber. After melted C

ни  резины подушечного сло  6 исчезает св зь между протектором 5 и каркасом 3, который под действием газа, выдел ющегос  при пиролизе резины/вспучиваетс . Кроме того, стальные нити 7 в обработанной зоне остаютс  отделенными от резиновых элементов покрышки.Under the rubber of the cushion layer 6, the bond between the tread 5 and the carcass 3 disappears, which swells under the action of the gas released during the pyrolysis of the rubber. In addition, the steel yarns 7 in the treated area remain separated from the rubber elements of the tire.

После вспучивани  каркаса 3 покрышку 4 вращают вокруг своей оси. Поворот осуществл ют на угол, при котором к рабочей части индуктора приближаетс  непрогрета  зона покрышки. В результате вспучивани  каркаса 3 по всему периметру покрышки 4 между каркасом 3 и протектором 5 образуетс  кольцева  полость 10, внутри которой скапливаетс  газ, выделившийс  при пиролизе резины, и обнаженные стальные йити (фиг,2). После этого каркас 3 и протектор 5 разрезают вдоль всего периметра покрышки 4. в результате чего она раздел етс  на две части, из которых легко извлекаютс  стальные нити 7 (фиг.З).After the frame 3 has expanded, the tire 4 is rotated about its axis. The rotation is carried out at an angle at which the unheated tire zone approaches the working part of the inductor. As a result of the swelling of the carcass 3 around the entire perimeter of the tire 4, between the carcass 3 and the tread 5, an annular cavity 10 is formed, inside which gas released during the pyrolysis of the rubber and exposed steel yarns accumulate (Fig. 2). After that, the carcass 3 and the tread 5 are cut along the entire perimeter of the tire 4. as a result of which it is divided into two parts, from which the steel threads 7 are easily removed (Fig. 3).

Дл  ускорени  процесса отделени  каркаса от протектора по обе стороны от зоны нагрева устанавливают прижимы 9 (фиг.4 и 5). При этом выдел ющийс  газ сохран етс  в обрабатываемой зоне и интенсивно отрывает каркас 3 от протектора 5. Кроме того, в описанном случае предотвращаетс  полна  утечка газа из полости 10 через отверсти , которые могут встретитьс  а отдельных местах протектора или каркаса.To accelerate the process of separating the frame from the tread, clamps 9 are installed on both sides of the heating zone (Figs. 4 and 5). In this case, the evolved gas is stored in the treated area and intensively tears the frame 3 from the tread 5. In addition, in the described case, the complete leakage of gas from the cavity 10 through openings that may occur in certain places of the tread or frame is prevented.
